Technical Field

The invention relates to a holding element for a device for supporting and/or guiding a machine tool, a tool or a workpiece, wherein the device has an abutment body with an abutment surface for abutment against a work surface of the workpiece or a wall.

Background

An abutment body in the form of a guide rail along which a hand-held power tool can be guided is described, for example, in DE 102008059838 a 1. The guide rail is loosely placed on the workpiece, so to speak, wherein a friction-fit component, for example a rubber element or the like, is arranged as a holding element on its underside, as a result of which the guide rail is held in place to some extent.

A guide rail which is held magnetically on a workpiece is known from DE 202013104555U 1. The circular bore teaching is described in DE 202016003907U 1. DE 102007009641 a1 relates to a device for guiding a milling tool with a suction head.

However, for precise workpiece machining, for example for saw cutting, this treatment is not sufficient. It is then possible, for example, to screw the guide rail to the base or to punch a nail through the guide rail, for which purpose the guide rail shown in DE 102008059838 a1 has, for example, holes at its front and rear longitudinal ends, respectively. Accordingly, the processing is difficult. In addition, the workpiece is damaged by nails or threaded fasteners used to fix the guide rail.

Disclosure of Invention

In order to solve this object, provision is made in a retaining element of the type mentioned at the outset for the retaining element to have an adhesive means for adhering to the working surface and a fastening means for releasable retention at the abutment, wherein the fastening means comprises at least one positive-locking contour for positive-locking retention at a retaining element receptacle of the abutment.

The worn holding element can thus be replaced by another holding element that is not worn. The holding element, the adhesive surface of which is no longer adhered, can thus be replaced by another holding element, for example. However, the replacement of the alternatively operating or operating holding element is also simply carried out in this way. The holding element with the adhesive surface can thus be exchanged, for example, with a holding element with a suction section.

The retaining element can thus be fixed to the abutment in a form-fitting manner, wherein the form-fitting portion represents the fixing means. The fixation means can also comprise a plurality and/or different fixation means, as it becomes still clearer.

The basic idea is that the holding element fixes the contact body to the workpiece in a releasable manner, for which purpose an adhesive means is provided, which can be removed from the working surface, in particular without leaving residues, without damaging the working surface. This enables, for example, sensitive workpieces to be machined. Nevertheless, the abutment body has a fixed hold at the working surface, so that, for example, a tool machine, such as a saw, a milling cutter or the like, can be positioned, for example fixed, relative to the workpiece.

The abutment body is, for example, a component of a machine tool or is suitable for guiding a machine tool. However, the abutment can also be used for guiding a hand-held tool, in particular a cutting tool, to be operated manually, for example. Furthermore, the abutment body can support the workpiece.

The fastening means for fastening the holding element to the contact body can comprise a plurality of variants, for example form-fitting fastening, plug receptacles or the like. Furthermore, it is possible for the holding element to form, as it were, a latching element which can be latched to the abutment.

The fastening means advantageously has at least one form-fitting contour at the retaining element for form-fitting retaining at a retaining element receptacle, in particular a recess, and/or at least one rear gripping surface, for example a cutout, for the retaining element of the abutment body.

The contact body preferably has at least one holding element receiver for a holding element. The holding element receptacle preferably extends from the contact surface of the contact body to an upper side opposite the contact surface. Thereby, the holding element can be introduced into the holding element receptacle from the upper side. Preferably, the contact surface is arranged at the plate-shaped section of the contact body and/or next to the guide receptacle or guide projection and/or at the flat guide surface.

The at least one holding element receptacle of the abutment body is advantageously accessible from a side of the abutment body facing away from the abutment surface, in particular from a side opposite the abutment surface, or is open at said side or has an opening at said side.

The at least one holding element receptacle is preferably arranged next to and/or close to and/or outside a guide contour of the abutment body, which is provided for guiding a tool or a tool machine. The guide contour is or comprises, for example, a guide rib which projects forward of the upper side of the abutment body or guide rail, said guide rib preferably being open toward the abutment face.

The holding element preferably has a planar contour or a contour at which the tool or the tool machine is guided or supported at the abutment and/or can be guided movably over the holding element accommodated in the holding element accommodation, without projecting beyond a guide surface or a support surface, in the state accommodated in the holding element accommodation, when it fixes the abutment with respect to the working surface.

Preferably, the holding element is accessible from an upper side of the contact body opposite the contact surface, for example, for adjustment between the positioning state and the adhering state, but in the adhering state projects maximally far in front of the upper side at the upper side of the contact body, so that a tool or a machine tool can be guided along the upper side of the contact body parallel to the contact surface or across the holding element with a directional component parallel to the contact surface of the contact body. For example, the holding element projects with a predetermined maximum value in front of the upper side of the abutment body or is aligned with the upper side or is retracted behind the upper side.

The holding element can be brought directly into the adhesive state when introduced into the holding element receptacle of the abutment. However, it is also possible for the holding element to be able to be pre-positioned in the holding element receptacle or to occupy a pre-positioned state in which the holding element is at least partially held in the holding element receptacle and the adhesive means is still in the positioned state. The abutment body can then be adjusted relative to the working surface. In the pre-positioned state, for example, there is a spacing between the adhesive surface of the adhesive device and the work surface of the workpiece or wall. The pitch can be, for example, a parallel pitch. However, it is also possible for the holding element to be pivoted out of the holding element receptacle in the pre-positioned state and/or to have an arcuate course, in particular in the region of the adhesive surface of the adhesive means. The holding element is then accommodated in the holding element receptacle in a movable manner, for example in a pivotable and/or displaceable manner, in particular in a translatory or linear manner, and/or in a deformable manner, in order to adjust the adhesive means from the positioned state into the adhesive state.

Advantageously, the form-fitting contour has at least one rear gripping contour for at least one rear gripping surface of the holding element receptacle of the rear gripping abutment, wherein the rear gripping contour supports the rear gripping surface of the abutment when it is in abutment against the rear gripping contour in the sense of holding the abutment against the working surface by means of at least one supporting force component directed in the direction of the abutment surface. That is to say that the rear gripping surface runs, for example, parallel or obliquely to the contact surface. Preferably, the rear gripping contour has at least one rear gripping section which extends parallel or with a directional component parallel to an adhesion surface of the holding element, by means of which the holding element can be adhered at the work surface. For example, the rear gripping surface can run obliquely to the contact surface and the rear gripping contour can run obliquely to the adhesive surface.

The at least one rear gripping profile comprises, for example, a dovetail profile, a supporting tab, a hook or the like. The combination is feasible without problems. At the holding element receptacle of the contact body, there is a mating contour that cooperates with this, for example a support surface for supporting a projection, a hook receptacle or a support surface for supporting a hook of a hook. The dovetail profile engages positively into a complementary dovetail mating profile.

Preferably, the holding element receptacle has a rear gripping surface at the mutually opposite sides and the holding element has a rear gripping contour at the mutually opposite sides associated with the mutually opposite sides of the aforementioned holding element receptacle. The rear gripping surfaces can run obliquely towards one another, for example in the form of funnels, or parallel. For example, the rear gripping surface can be arranged on the side of the contact body opposite the contact surface. The rear grip contour can, for example, run obliquely to the adhesive surface of the adhesive means, but can also run parallel to said adhesive surface.

The holding element can be inserted and/or pivoted into the holding element receptacle, for example. Preferably, the holding element then bears with a form fit against at least two mutually opposite or opposing sides of the holding element receptacle. It is possible for the holding element to be mounted in the holding element receptacle so as to be displaceable along the opposite side. The cut-out at the holding-element receptacle prevents, for example, the holding element from being able to come out of the holding-element receptacle in the direction toward the device to which it is attached or in the direction toward the working surface.

The holding element receptacle can, for example, comprise a window or a passage opening, which extends between the contact surface of the contact body and an upper side opposite the contact surface. The holding element can be inserted into a through-opening, which in this respect represents an insertion opening or a plug receptacle, so that, for example, in the inserted state, the adhesive means lies in a plane with the contact surface or projects in front of the contact surface. The retaining element can be inserted along its insertion axis into the retaining element receptacle preferably at least with a directional component or overall at right angles to the contact surface of the contact body.

It is also possible for the holding element, when fitted or arranged in the holding element receptacle, to be able to be pivoted from the positioning state into the adhesive state. In this case, the holding element can have a pivot section and/or the holding element can pivot in the holding element receptacle when it is at least partially in engagement with the holding element receptacle. In this way, it is possible for the holding element to be received in a holding element receptacle of the abutment so as to be pivotable for adjustment from the positioning state to the adhering state.

It is possible that the holding element is accommodated in the holding element receptacle in a movable or displaceable manner, so that the holding element as a whole and/or the adhesive means can be brought, by an adjustment, in particular a displacement, in the holding element receptacle into an adhesive state, in which the adhesive means is not yet in contact with the working surface and/or is arranged after the contact surface, in which state the adhesive means adheres to the working surface and fixes the contact body at the working surface. It is possible that the holding element is flexurally flexible in the described embodiment and can be brought from the positioning state into the adhering state not only by its flexurally flexible but also by displaceability or adjustability in the holding element receptacle.

It is also possible, however, for the holding element to be flexurally rigid. The flexurally rigid holding element can advantageously be brought from the positioning state into the adhering state by means of an adjustment, in particular a displacement and/or a pivoting movement, within the holding element receptacle. For example, the holding element is displaceably and/or pivotably accommodated in the holding element receptacle with a directional component toward the contact surface of the contact body.

Furthermore, it is possible for the holding element receiver to have a longitudinal guide for guiding the holding element along a longitudinal axis, which extends, for example, parallel to the contact surface or has a directional component parallel to the contact surface. The longitudinal guides can be closed at the longitudinal ends, that is to say designed in the manner of notches. Preferably, the longitudinal guides are open at their longitudinal end regions, so that the holding element can be introduced into the same longitudinal guide at one longitudinal end region of the longitudinal guides and can be discharged from the longitudinal guides at the other longitudinal end region. This results in a bidirectional, almost unlimited displaceability of the abutment body relative to the retaining element, for example.

The at least one form-fitting contour of the holding element is preferably arranged at the side or upper side of the holding element opposite the adhesive means or the adhesive surface of the adhesive means.

The at least one form-fitting contour of the holding element can, for example, comprise one or more supporting projections.

Preferably, the holding element has at least one supporting projection extending transversely to the adhering means, in particular to the adhering surface of the adhering means, for supporting on a supporting contour of the adhering means which is parallel to the adhering surface or inclined at an angle of less than 90 ° to the adhering surface, for example, a parallel or substantially parallel orientation of the adhering means with respect to the adhering surface of the adhering means or for holding. The at least one supporting projection is for example a hook-like projection or comprises a hook-like projection.

The at least one support tab suitably forms an integral part of an assembly of a plurality of support tabs. Preferably, the holding element has at least one support projection at mutually opposite sides, respectively, but in particular a row of support projections arranged adjacent to one another. The supporting projection can be, for example, a hook projection or a supporting hook. The at least one support projection can, for example, engage into a rear gripping surface or a cut-out surface of the abutment. The rear gripping surface is arranged, for example, on the upper side of the contact body opposite the contact surface. The support projection therefore takes care, for example, that the contact body cannot be removed from the holding element in a direction of movement having a component of movement at right angles to the working surface or the contact surface.

The contact body expediently has an upper side opposite the contact surface, which forms or is arranged with a support contour. For example, the support contour is designed as an inclined surface at the holding element receptacle already described as a through-opening. However, it is also possible for the upper side itself to form the support contour, i.e. for example the hook-shaped projection or a further part of the support projection to bear directly on the upper side of the contact body.

Furthermore, the support contour can comprise a guide receptacle of the linear guide or form such a guide receptacle, while the at least one support projection forms a guide projection for linearly guiding the holding element at the abutment and engages into the guide receptacle. The guide receptacle can be designed, for example, in the form of a groove. Furthermore, the guide receptacle is advantageously designed in the form of a cut-out or a guide groove.

Preferably, the holding element has at least one support surface for supporting the contact body at an angle, for example at right angles, to the adhesive surface of the adhesive means, so that the contact body is supported at the holding element with respect to forces acting parallel to the contact surface. The support surface preferably relates to the already mentioned slide surface. At least one latching projection or a further latching contour is preferably arranged at or next to the support surface.

The at least one support surface preferably comprises a plurality of support surfaces, for example provided at mutually opposite sides of the holding element. The support surface is preferably arranged such that it supports the holding element against the contact body with respect to all forces acting parallel to the contact surface.

Preferably, the retaining element is designed as a latching element. Preferably, the latching assembly is provided as a securing means for latching the retaining element with the abutment body. The latching assembly can, for example, comprise a latching hook, a latching projection, a latching tongue or the like, which snaps into a corresponding latching receptacle. In other words, the latching assembly comprises, for example, a latching contour at the holding element, which latching contour can be brought into engagement with a latching counterpart contour at the abutment.

The latching assembly expediently has at least one latching contour for latching the retaining element with the abutment, wherein the latching contour has a sliding surface or is arranged on the sliding surface, by means of which the retaining element is mounted on the abutment in a manner that it can be displaced in a sliding manner between the positioning state and the adhering state. The holding element can be slid, for example, by means of at least one sliding surface (preferably provided with a plurality of sliding surfaces) along a holding element receptacle, for example a through-opening, of the already mentioned abutment, in order to be able to speak to pass through the abutment into abutting contact with the working surface and establish an adhering state.

The sliding surface is provided, for example, at the already mentioned supporting projections or supporting hooks.

It is also advantageous if the fastening means has or comprises an adhesive portion, by means of which the holding element is adhered to the contact body. In this case, the releasable bond is again advantageous, i.e., the holding element can be removed from the abutment without problems and the other bonded holding elements can be replaced.

In the case of an adhesive bonding of the holding element to the abutment, it is advantageous if the adhesive bond and the adhesive means are arranged on mutually opposite sides of the holding element. The holding element can thus be bonded, for example, to a surface next to the contact surface of the contact body, while the contact surface of the contact device or the contact device is aligned with the contact surface or lies in a plane with the same contact surface. Obviously, the adhesive means or the adhesive surface of the same adhesive means can also project slightly in front of the abutment surface.

Preferably, the holding element has at least one support or latching contour, by means of which the holding element is supported in the positioned state at a bearing or support contour of the holding element receptacle and which can be moved past the bearing or support contour of the holding element receptacle by force application of the holding element in the direction of the adhering state.

It is preferably provided that the adhesive means can be brought from a position state, in which the adhesive means is not in contact with the working surface and the working surface can be positioned relative to the working surface, into an adhesive state, in which the adhesive means adheres to the working surface and fixes the abutment on the working surface, with the abutment surface of the abutment abutting against the working surface.

In the following description, not only the above-described positioning state (in which the adhesive means is already arranged at the abutment, as it were) but also a state in which the retaining element is not arranged at all at the abutment, for example for the purpose of its transport but also covered by a cover or the like, is to be understood as a positioning state. The adhering state is a state in which the holding member is adhered at the abutting surface.

In the adhered state, the adhering means preferably lies in a plane with the contact surface or projects in front of the contact surface.

The adhesion surface and the abutment surface of the adhesion device are preferably parallel and/or in one plane when the adhesion device is in the adhesion state.

It is understood that the device can have not only a holding element but also a plurality of, for example two or three holding elements. The holding elements are arranged, for example, one after the other in a working direction, along which the tool can be guided along the abutment. It is understood that there can be holding element receptacles at the contact body for both the holding element and for a plurality of, for example two or three holding elements. The holding elements are arranged, for example, one after the other in a working direction, along which the tool can be guided along the abutment.

The holding element preferably has a plate-like or disk-like shape.

Preferably, the holding element is strip-shaped and/or has a longitudinal profile.

Preferably, the holding element is strip-shaped and/or has a longitudinal profile.

The holding element as a whole or at least one component of the holding element, for example the carrier body of the holding element, the adhesive means or the like, is preferably made of plastic and/or compostable or biologically decomposable.

The abutment body is preferably made of metal, in particular aluminum. Preferably, the abutment body is a profile body and/or an extruded profile.

Advantageously, the holding element has parallel-running, straight longitudinal sides. For example, the holding element is rectangular in plan view. However, at one or both longitudinal ends, the longitudinal sides can also be connected to one another by rounded sections, in particular overlapping sections or gripping sections. It is understood that also other outer circumferential geometries, such as circular, elliptical or polygonal holding elements, are possible without problems.

Several alternative and additional variants are conceivable for the design of the adhesive means. For example, adhesive devices have an adhesive surface for adhering to a work surface. The adhesive means can also have a suction section or a suction profile. For example, the adhesive device can also comprise a suction head, in particular an assembly of a plurality of suction heads, for sucking onto the work surface. The suction heads can be arranged adjacent to one another. In principle, it is also possible for the adhesive means to comprise or be formed by a hook-and-loop layer (Klettschicht). It is also possible for the adhesive surface to be divided or for there to be a plurality of adhesive surfaces.

The adhesive device can be designed for adhering to rough surfaces, such as wood material, stone or the like. For this purpose, the adhesive means preferably has an adhesive means or an adhesive surface. It is also advantageous, however, that the adhesive means is capable of adhering to smooth surfaces, such as slate, glass or the like. The adhesive device can also be provided with an adhesive surface, but can also be provided with a suction surface, in particular a suction head.

The design of the adhesive, i.e. the adhesive surface, is preferably such that the adhesive can be removed from the working surface without leaving residues. Preferably, the adhesive means has an adhesive strip or layer. For example, the adhesive means is formed by an adhesive that can be removed without residues, as described, for example, in WO 92/11332 a1 or in the references mentioned therein. It is particularly advantageous, that is to say that the adhesive does not realize a permanent adhesive bond, but a releasable adhesive bond, as is known, for example, in the case of adhesive notes, which can be removed from the base without residues and easily. It is clear that the adhesive is in the present case preferably somewhat more permanent, that is to say that detachment of the adhesive is somewhat more difficult. Nevertheless, the adhesive means is preferably designed such that it can be removed from the working surface without residues. Preferably, the adhesive means relates to a so-called foam adhesive.

Adherent devices include, for example, acrylate materials. In order to adhere the adhesive means to the carrier body of the holding element or directly to the contact body, it is advantageous, for example, to use a modified acrylate compound, so that the holding element is firmly adhered to the carrier body. The adhesive means advantageously comprises a so-called pure acrylate material at the side thereof which is provided for adhering to one of the working surfaces. The pure acrylate material can be removed from the working surface without residues.

The adhesive device or the holding element as a whole can be a sandwich-type adhesive device and/or have a plurality of layers, for example layers made of different acrylate materials, for example a modified acrylate material and a pure acrylate material. Furthermore, a reinforcing membrane, in particular a reinforcing membrane made of polyurethane, PET or the like, and/or a foam layer, in particular a foam layer made of polyurethane foam, can be provided at the adhesion device or the holding element.

The working surface relates, for example, to a workpiece surface, for example a workpiece surface of a wood workpiece, a plastic workpiece or the like. However, the adhesion at the wall, for example a building wall or a room wall, can also be achieved without problems in this way.

Basically, the contact body can also be displaced or adjusted without problems at the surface in the positioned state, i.e. the adhesive means can be regarded as inactive. The positioned state can also be referred to as an inactive or unactivated state of the adherent device. However, when the abutment is brought into the proper position relative to the working surface, the adhesive means is activated or brought into the activated state, as it were. In this way, the adhesive means is brought into an adhesive state in which it adheres to the work surface and is thereby fixed both to the work surface and to the abutment.

In order to adjust or bring the holding element from the positioned state into the adhered state, a number of possibilities are advantageous:

for example, it can be provided that the holding element is arranged on a part of the contact body that is movable with respect to the contact surface, for example, can be moved in a pivoting manner, can be moved in a displacing manner, or the like, so that the adhesion means can be adjusted from the positioned state into the adhesion state by actuating the movable part. However, the movable part can also be a flexurally flexible part of the abutment. In this way, for example, a flexurally flexible section or projection can be provided in the region of the working surface or next to the working surface at the contact body, at which section or projection an adhesive means is arranged. Thus, the abutment body can be said to form a component of the holding element itself or in any case a handling device for the same holding element.

However, it is also possible for the device to have a bearing mechanism for movably supporting the holding element, for example for adjusting the holding element from the positioned state into the adhering state or from the adhering state into the positioned state. However, it is also possible for the bearing means to be used to enable the holding element and the abutment to be positioned relative to one another. Thus, for example, it is possible for the holding element to be mounted on the contact body so as to be displaceable in a plane parallel to the contact surface, so that the contact body can be moved relative to the holding element when the holding element has been adhered to the working surface.

When supporting means are provided, fixing means, such as clamping means, latching means or the like, for fixing the holding element and the abutment relative to one another are preferably provided. The abutment body can then be fixed, for example, relative to the holding element, so that it retains its position.

The holding element is expediently mounted so as to be pivotable at the bearing means in order to pivot the adhesion means into the adhesion state towards the contact surface or the working surface and/or away from the contact surface or the working surface in the sense of disengaging the adhesion means from the working surface. For example, it is possible to position the abutment on the working surface and then to pivot the holding element in the direction of the adhering state, so that the entire arrangement comprising the abutment and the holding element is fixedly secured on the working surface. For the decoupling process, the pivot bearing is also advantageous. The adhesive means can thus be pivoted away from the working surface, for example, in a stripping process, so that the holding element and thus also the abutment are free of the working surface.

The bearing mechanism can, however, also comprise a displacement bearing at which the holding element is displaceably mounted toward the abutment. The displacement direction or displacement axial direction of the displacement support is preferably orthogonal to the abutment surface. For example, it is possible for the adhesive means to have an adhesive surface which is oriented parallel to the contact surface. The support means preferably effect a parallel displacement of the adhesive surface in the direction towards the abutment surface in order to establish an adhesive contact with the working surface. For example, the adhesive surface can be designed as an adhesive surface. However, it is also possible for the adhesive surface to be delimited, for example, by an outer circumferential contour of the suction portion, in particular of a free region of the suction head. When there are a plurality of adhesive surfaces, the adhesive surfaces are preferably arranged in or at the envelope surface or envelope plane.

The holding element can be flexurally rigid and/or flexurally flexible. For example, the holding element can be flexurally flexible or have flexurally flexible sections in one or more directions. It is also possible that the holding element as a whole is flexurally rigid in one or more directions. The holding element can have at least one flexurally rigid and at least one flexurally flexible section. For flexural rigidity, for example, one or more reinforcing ribs and/or a plate-like profile of the holding element or the carrier body or the like are advantageous. For the property of bending flexibility, for example, correspondingly bending-flexible materials of the holding element or the carrier body, such as plastics, and/or deformation pockets or the like at the holding element, are suitable.

It is furthermore possible for the holding element to be flexurally flexible for adjustment between the positioning state and the adhering state. The holding element can thereby be brought from the positioning state into the adhering state, for example, in a rolling or unwinding movement. The adhesive means is effective immediately here, i.e. it can be brought into adhesive contact with the working surface, so to speak continuously or in a smooth process, or can be brought into an adhesive state due to the bending flexibility of the retaining element.

The following embodiments are advantageous, in particular when the holding element is flexurally flexible:

the holding element can advantageously be transferred from the positioning state into the adhering state in the supporting state, in which the holding element is supported in part, for example at one or both of its longitudinal ends, on the abutment. For example, the holding element can be arched between its longitudinal ends away from the contact surface, which corresponds to the positioning state. By pressing in the direction of the contact surface in the section between the longitudinal ends, the holding element can be brought or can be transferred into an adhesive state in which the adhesive means is then in a plane with the contact surface.

Advantageously, the holding element can be rolled or unrolled in the direction of the working surface in the sense of rolling on or unrolling the adhesive means. For example, the holding element as a whole or an adhesive body comprising or having an adhesive means can be said to roll onto the working surface. Thereby, the holding element can be brought into the adhering state, for example, from the positioning state. However, it is also possible for this rolling movement to be used, for example, to disengage the retaining element from the working surface. The holding element can thus advantageously be rolled up rollingly away from the working surface in the sense of being rolled up or off the adhesive means.

A preferred concept provides that the holding element has at least one recess and/or at least one transverse reinforcement, in particular a transverse rib, transversely to its longitudinal extension or transversely to a rolling direction provided for the winding or rolling of the holding element. Preferably, the transverse ribs and/or transverse reinforcements and/or recesses extend over the entire transverse width of the retaining element. The recess facilitates a winding operation or a bending operation of the holding member in a direction toward or from the adhered state. The transverse ribs or transverse reinforcement reinforce the holding element transversely to the longitudinal extension thereof.

The adherent device can be exposed in the positioned state. Thereby, an adhering state can be obtained, for example, by adjusting the adhering means or the adhering surface thereof in a direction toward the abutting surface or the working surface. It is clearly advantageous that such an adhesive device is also protected, for example for transport purposes, in particular by a cover section which is explained later. The cover part can, for example, already be removed from the adhesive device in the positioned state, so that the adhesive device is in principle directly ready for establishing the adhesive contact. However, it is also possible for the adhesive device to be covered in the positioned state by a cover section which can be removed from the adhesive device for bringing to the adhesive state.

The cover portion is, for example, film-like or planar. Advantageously, the cover portion comprises a cover membrane. It is furthermore expedient for the cover to completely cover the adhesive means. Thus, the adhering device can be said to be ineffective as long as the covering portion is disposed on the adhering surface or the adhering device.

The cover expediently has a cover section which covers the adhesive means and an actuating section which can be manually actuated by an operator into the positioned state, by means of which actuating section the cover section can be removed from the adhesive means, for example by a pulling action, and can be brought into the adhesive state. At the actuating section, for example, a handle or a gripping section is present. The handling section as a whole can also present a gripping section. For example, the gripping section is designed in the type of holding tongue or gripping tongue for gripping. The gripping section can be clamped, for example, between two fingers of an operator in order to manipulate the gripping section.

When the holding element is arranged or fixed at the abutment and/or the abutment is already arranged at the working surface, the gripping section of the actuating section projects, for example, before projecting laterally into the abutment and/or through a recess of the abutment for gripping by an operator. For example, a window or similar further recess can be provided at the abutment through which the actuating section or the gripping section protrudes, so that the operator can grip the actuating section or the gripping section.

It is also advantageous if the gripping section projects in front of a carrier body of the holding element having or carrying the adhesive means, for example in the longitudinal end region thereof.

In the positioned state, it is advantageous if at least a part of the actuating section abuts the cover section, for example flatly. It is also advantageous if the cover has at least one deflecting section between the actuating section and the cover section. Both are possible in combination. For example, the actuating section and the cover section can thereby be placed against one another and connected to one another via the switching section. Thus, for example, a detachment or removal of the cover section is possible without problems, for example by pulling the actuating section.

That is, the masking segment can be removed from the adherent device in this way. This arrangement is therefore particularly advantageous, since the cover sections can be removed from the adhesive device in the sense of being detached or rolled off. The adhering means can be said to be continuously or gradually brought into an adhering state. The actuating section and the covering section are preferably made of the same material, in particular in the form of a film. Thereby, the adhesive means can for example already rest against the working surface as long as it is still in the positioned state. The operator can then remove, for example remove, peel off or the like the covering part from the adhesive device by actuating the actuating section. In this case, it is possible for the already mentioned reversing section to roll or move along the surface of the adhesive means, in particular the adhesive surface.

The adhesive body of the holding element carrying or forming the adhesive means suitably has a processing section which can be manually manipulated by an operator in the adhered state, said processing section being, for example, graspable by the operator. The adhesive body can be manipulated by means of the processing section for bringing the adhesive means from the adhering state into a release state in which it is removed from the work surface of the workpiece. This allows the adherend to be removed as a whole. Such a manipulation is preferably possible when the abutment is resting against the working surface and/or when it is removed from the working surface.

The adhesive means suitably extends along the longitudinal axis of the adhesive body. Advantageously, the adhesive body can be stretched in the direction of its longitudinal axis by a pulling manipulation of the treatment section for detaching the adhesive means from the work surface. By stretching the adhesive means, preferably the adhesion of the adhesive means at the working surface is changeable or removable.

When the holding element is arranged or fixed at the abutment, the treatment section of the adhesive body advantageously projects before laterally projecting into the abutment and/or projects through a recess of the abutment for gripping by an operator. In this case, in particular, the treatment section can also be gripped by the operator when the abutment is in contact with the work surface. In this way, the entire device can be released from the adhesion at the working surface, in such a way that the adhesion body can be manipulated, for example stretched, as it were. However, it is also possible for the adhesive body to be detached from the workpiece or the wall or its working surface in a peeling or rolling-off movement.

The gripping section of the covering element and the handling section of the adhesive body are arranged, for example, at mutually opposite sides of the holding element. This presents a further option when the gripping section and the handling section are arranged at the same side of the holding element, for example at the same longitudinal end. This is advantageous in particular when the two components of the covering element, i.e. the treatment section and the gripping section, do not protrude as far in front of the holding element, so that they can be gripped together. It is particularly advantageous if the gripping section of the covering element projects farther forward of the holding element than the handling section of the adhesive body.

It is advantageously provided that the adhesion means can be adjusted between the positioned state and the adhesion state, for example can be brought from the positioned state into the adhesion state or from the adhesion state into the positioned state, by adjusting the retaining element with respect to the abutment, for example by adjusting the retaining element in or at a retaining element receptacle, for example a pocket, of the abutment provided for accommodating the retaining element.

Furthermore, it is advantageously provided that the adhesive means can be brought from the positioned state into the adhesive state by introducing the holding element into a holding element receptacle, in particular a recess, of the abutment body, which is provided for receiving the holding element. For example, the holding element can be inserted into the holding element receptacle in order to adjust it from the positioning state into the adhesive state.

It is preferably provided that the holding element has at least one support or latching contour for supporting the holding element in the positioning state at the abutment contour, wherein the support or latching contour can be moved past the abutment contour of the holding element receptacle for adjusting the holding element in the direction of the adhering state. The retaining element can be supported at a support contour of the retaining element receiver by means of a latching contour or a support contour, wherein the retaining element is already received in the retaining element receiver, but is not yet in the positioned state. The state can also be referred to as a pre-bit state. The holding element is advantageously held in a form-fitting manner at the holding element receptacle by means of a support contour or latching contour, however, the adhesive means is not yet in the adhesive state. The operator can still adjust the holding element or the adhesive means from the positioned state into the adhesive state by a further operating action, for example by pressing on the holding element in the direction of the contact surface of the contact body.

Advantageously, the holding element has a control handle by means of which the adhesive means can be brought from the positioned state into the adhesive state by an operating operation, in particular a pressing operation in the direction of the contact surface or a pulling operation by an operator. The operating handle can, for example, be arranged at the side of the adhesive element opposite to the adhesive means. For example, the actuating handle can be arranged at the upper side of the adhesive element or formed by the upper side of the adhesive element. The actuating handle can, however, also comprise, for example, a pulling strap or similar other actuating elements.

In the case of the design and/or arrangement of the actuating handle, a plurality of possibilities are provided, for example when the holding element is arranged on the abutment body, in particular in a holding element receptacle of the abutment body, before the actuating handle projects laterally into the abutment body and/or is accessible for actuating the actuating handle from a side of the abutment body facing away from the abutment surface of the abutment body, in particular the opposite side.

Further possibilities for fastening the holding element to the base are provided by the following measures:

advantageously, the holding element has one or more through-openings for fixing pins, for example threaded fasteners or nails, by means of which the holding element can be connected to the work surface. In this connection, it should be mentioned that the described design of the holding element represents an independent invention, which can be detachably fixed, for example latched, connected by means of a plug connection or the like, by means of form-fitting fixing means, on a guide body for or as a component of the machine tool, for example a guide rail for the machine tool or a guide body of the machine tool, for example a support foot. An adhesive means for releasable adhesion to the work surface, such as an adhesive, a suction means or the like, is in this case optionally possible, but not necessary, in the holding element. This is a separate invention, but can also be a development or design of the invention mentioned at the outset, in particular if the holding element can be detachably fixed to the abutment or the guide body already in contact with the working surface, in particular in the case of the guide body already in contact with the working surface, and then the holding element can be connected to the working surface by means of a nail or another fixing pin.

The abutment body preferably forms a guide body, for example for a machine tool or a workpiece. For the function as a guide body, the abutment body preferably has at least one guide contour, for example a guide projection extending along its longitudinal extension. The guide body can also have or comprise a machine support which supports the machine tool on the guide body in a displaceable, pivotable or both manner. The machine support can for example have a pendulum support. The machine support can also have or comprise one or more guide elements, in particular at least one guide bar, which extend transversely, for example perpendicularly, to the contact surface. For example, at least one guide element forms part of a linear bearing, by means of which the machine tool can be moved in a direction toward the contact surface and thus toward the workpiece or the wall or away from the workpiece or from the wall.

The abutment body can be, for example, a guide body, such as a ruler or the like, for a tool, in particular a cutting tool, such as an indenter (Anritzer), a glass cutter or the like, which can be actuated manually.

Furthermore, it is possible for the abutment body to form a component of a tool machine, for example a work table, by means of which the tool machine can be arranged on the work surface. The holding element is responsible for fixedly holding the guide body at the working surface.

The tool machine and the abutment can also be components separate from one another, which are brought into contact with one another only for the purpose of a work operation, for example for the purpose of introducing a saw cut into a workpiece.

The guide body can also form a guide rail, the underside of which has or forms the contact surface of the contact body and the upper side of which, opposite the underside, has a sliding surface for displacing the machine tool. At or beside the sliding surface, for example, the already mentioned elongated guide profiles, for example guide grooves or guide projections or guide ribs, are advantageous. Thereby, the guide rail can be said to present a sliding rail for the tool machine.

Furthermore, a system comprising the abutment and the machine tool is preferred. The abutment can form part of a machine tool, such as a guide table, a machine base or the like.

A holding means, for example an angle surface, a support surface or the like, can be provided on the contact body for fixing a further object or the like for hanging on the object.

The abutment body can be plate-shaped. The abutment can be or comprise a guide rail.

However, the contact body can also have at least two legs which are angled relative to one another, wherein a holding element of the type mentioned above is arranged or can be arranged at least one of the legs. For example, a receptacle for the holding element, in particular a support receptacle or a holding receptacle, is provided at one of the legs. The abutment body can also have a plurality of legs which are angled relative to one another. For example the legs can form a U-shaped configuration. Furthermore, the contact body can have a base leg, at which a retaining element is or can be arranged, from which retaining element one or both side legs project. Furthermore, advantageously, a further lateral leg projects from one of the lateral legs, preferably parallel to the base leg of the abutment.

The tool machine can, for example, relate to a saw, in particular a circular saw, a plunge saw, a wire saw or the like. The tool machine can also be a drilling machine, a milling machine, in particular a milling cutter, or the like. The machine tool is preferably a hand-held machine tool. The power tool has a drive motor, for example an electric drive motor, for driving a tool receptacle, at which a working tool, for example a saw blade, a drilling head, a milling head or the like, is or can be arranged.

Detailed Description

The system 10A comprises a machine tool 20 having a guide element 21 and a drive unit 22 which is arranged, in particular pivotably supported, at the guide element 21. The drive unit 22 has a drive 23, for example a drive motor, which drives a working tool 24, for example a saw blade, directly or via a gear mechanism not shown in the figures.

It is now possible for the guide element 21 to be positioned directly on or along the workpiece W, for example, in order to introduce a saw cut into the working plane H. However, the accuracy in the case of such workpiece machining is not optimal.

It is therefore provided that the machine tool 20 is guided along the device 30, which in this respect forms a guide device, for example with an abutment 40, which is profiled in the form of a guide rail 41. The guide rail 41 and thus the abutment 40 have an abutment face 42 provided for abutment at the working face H and an upper side 43 opposite the abutment face 42, along which the guide element 21 and thus the tool machine 20 (in the present case a saw) can be guided. The abutment body 40 is plate-shaped and has elongate longitudinal sides 44, 45 and end or longitudinal end sides 46.

A schematically illustrated, manually or guidable or retainable tool 120 having a working tool 121, for example a scraping tool, can also be guided or supported at the abutment 40.

At the upper side 43, for example the sliding surface, a guide projection 48A, i.e. a guide contour 48, is furthermore provided for guiding the machine tool 20 along the longitudinal extension L of the abutment 40. For example, the guide projection 48A engages in the guide receptacle 25 at the guide element 21. The guide projection 48A is, for example, a longitudinal rib, and the guide accommodating portion 25 is a longitudinal groove.

The guide contour 48 projects in front of the plate-like section 54 of the abutment body 40.

For example, the tool machine 20 and/or the tool 120 can be guided along the abutment 40 along the working direction AR or the longitudinal extension L, in particular supported or guided at the guide contour 48 or the guide projection 48A.

Next to the guide contour 48, in particular in the region of the plate-shaped section 54, in particular a strip-shaped guide surface 54A is provided, which extends along the longitudinal extension L of the abutment 40 and on which the guide element 21 of the tool machine 20 slides when moving along the longitudinal extension L.

Work tool 24 is guided along longitudinal side 44. At the longitudinal side 44, for example, a lip 47 is provided which exhibits chip protection and is preferably cut off by means of the working tool 25 during the first saw cut.

When the abutment 40 is lowered onto the workpiece W, the contact surface of the lip 47 facing or associated with the working surface H lies on the working surface H. Furthermore, the abutment body 40 and thus the guide rail 41 are supported on the work surface H by a bearing element 49, for example a strip made of rubber or similar other elastic material. The bearing element 49 and the bearing surface of the lip 47 form the bearing surface 42 of the bearing body 40.

The bearing element 49 and the lip 47 are arranged on a profile body 50, on which the guide contour 48 and the upper side 43 or sliding side of the guide rail 41 are formed. The profile body 50 can also have further profile profiles for guiding or supporting the tool machine 20, but these are not discussed in more detail.

Advantageously, a receptacle 51 is also provided on the longitudinal side 45 of the contact body 40, which receptacle is suitable, for example, as a holding receptacle for a holding element to be described, for example, a fastening 861 for such a holding element. The fixing portion 861 is held by means of a clamping body 891, for example of the slider (Nutensteins) type, which can be introduced and/or engaged into the housing 51 and which can be clamped in the housing 851 by means of a clamping threaded fastener 892. The receptacle 51 is an elongated receptacle, so that the fastening part 861 or the holding element can be displaced along the longitudinal extension L of the abutment body 40 into different longitudinal positions.

Although the contact surface 42 is advantageously friction-fitted, that is to say the contact body 40 is held at the working surface H with a predetermined friction or holding force on account of the relatively soft and/or adhesive contact surface 42. However, particularly high forces can occur just during the saw cut into the workpiece W, so that the contact body 40 slides at the working surface H. The following measures are provided for remedy:

the abutment 40 can be provided, if necessary, with a holding element 60, which in turn has an adhesive means 70. The adhesion means 70 is for example an adhesive layer or comprises an adhesive layer. The adhesive face 71 of the adhesive means 70 is adapted to be releasably adhered to the working face H.

The adhesive means 70 are arranged on a respective carrier body 80 of the holding element 60, which carrier body can be connected in a form-fitting manner to the abutment body 40 in a releasable manner.

The carrier body 80 forms an insertion body and/or a clamping body and/or a latching body, which can be inserted into the contact body 40, i.e. the holding element receptacle 55 of the guide rail 41. The holding element receptacle 55 advantageously forms a plug receptacle 55A.

The holding element receptacles 55 have opposing long longitudinal sides 56 which extend between longitudinal end sides 57 of the respective holding element receptacle 55. The longitudinal sides 56 expediently run straight parallel to the longitudinal extension L of the abutment 40. The longitudinal end side 57 is, for example, round, linear or the like.

The holding element receptacle 55 is arranged, for example, at a distance from the end face or longitudinal end face 46 of the contact body 40. It is also possible without problems to provide additional or differently arranged holding element receptacles. Thus, for example, the retaining element receiver 55 does not necessarily have to run parallel to the longitudinal extension L, i.e., the longitudinal sides 56 run parallel to the longitudinal extension L. It is also possible without problems, for example, for the longitudinal sides 56 to run parallel to the longitudinal end sides 46 of the contact body 40.

Proceeding from the upper side 43 of the contact body 40, the edge of the holding element receiver 55 is inclined or has an inclined portion 58. This simplifies, for example, the insertion of the respective retaining element 60. For example, the inclined portion 58 runs funnel-like.

The upper side 43 of the abutment body 40 and the inclined portion 58 form a support contour 53, for example, for supporting a projection 85.

When the holding element 60 is inserted into the holding element receptacle 55, it is supported with its longitudinal side 66 at the longitudinal side 56 of the holding element receptacle 55 and with its longitudinal end 67 at the longitudinal end 57 of the holding element receptacle 55.

The longitudinal sides 66 and the longitudinal ends 67 or wall surfaces provided there form part of a form-fitting contour 90, by means of which the holding element 60 is supported in a form-fitting manner at the holding element receptacle 55 with a directional component parallel to the adhesive surface 71. The form-fitting contour 90 is, for example, a fastening means 90A.

In order to support the holding element 60 on the holding element receptacle 55 in a form-fitting manner with a directional component perpendicular to the adhesive surface 71, so that the contact body 40 is prevented from being able to be removed from the working surface H when the adhesive element 60 is adhered to the working surface H, a rear gripping contour 91 is provided. The rear gripping contour 91 is supported on the upper side 43 of the abutment body 40 or on a support surface or rear gripping surface 95 of the abutment body 40, which is explained below. The rear gripping contour 91 is provided at the support projection 85, more precisely at the hook-like projection 87 thereof.

The holding element 60 has a supporting projection 85 at its longitudinal side 66. The support protrusions 85 are arranged adjacent to each other in a row arrangement. The support tab 85 has a longitudinal leg 86 and a hook-like tab 87. The longitudinal leg 86 has a support surface 88 for positive support at the wall surface 59 of the abutment body 40 extending at the inner circumference of the retaining element receiver 55. The wall surface 59 extends from the inclined portion 58 toward the abutment surface 42 or the underside of the abutment body 40. The wall surface 59 is, for example, perpendicular to the abutment surface 42. The hook-shaped projection 87 is chamfered in its transition region to the support surface 88, so that it can bear in a form-fitting manner against an inclined portion 58 of the retaining element receptacle 55, at which a rear gripping surface 95 is provided.

Preferably, the support projection 85, in particular the longitudinal leg 86 thereof, is elastically yielding, so that the holding element 60 can be clamped into the holding element receptacle 55, as it were, i.e. the holding element 60 can be clamped with the holding element receptacle 55.

Furthermore, it is advantageous if a latching projection 89 is provided on the longitudinal leg 86 facing the wall surface 59, said latching projection being able to engage in a latching recess not shown in the drawings on the wall surface 59.

Advantageously, the latching or supporting projection 85 is integral with or formed by the carrier body 80.

The carrier body 80 is stiffer than the adherent means 70, but nonetheless is flexurally flexible. The carrier body 80 has transverse reinforcement 81, for example extending transversely to its longitudinal extension. The transverse reinforcement 81 preferably extends between the support projections 85 and is designed, for example, as a reinforcement rib. The transverse reinforcement 81 is arranged at the upper side 82 of the carrier body 80 and the adhesion means 70 is arranged at the lower side 83 thereof. Thus, between the transverse reinforcing bodies 81 there are recesses 84 which effect a rolling or bending movement of the carrier body 80 and thus of the holding element 60.

The positioning of the abutment body 40 on the working surface H takes place, for example, as follows:

first, the abutment body 40 or the guide rail 41 is positioned at the work surface H to a desired position so that its abutment surface 42 is in the desired position on the work surface H. The contact body 40 is then fixed to the working surface H by means of one or more holding elements 60, the adjustment of which between the positioning state PZ, as shown for example in fig. 2 and 4, and the adhering state HZ, as shown for example in fig. 6, can be effected in different ways.

The assembly possibility of the holding element 60 at the holding element receptacle 55 and thus at the contact body 40 is provided, for example, by first inserting a longitudinal end portion 61 at a longitudinal end of the holding element 60 into the holding element receptacle 55, wherein the longitudinal end portion 61 is supported and/or contacted at the longitudinal end 57 at the holding element receptacle 55. Between the adhering portion 63 of the holding element 60, where the form-fitting contour 90, in particular the supporting projection 85, is provided, and the longitudinal end portion 61, the holding element 60 is, for example, flexurally flexible. In this way, for example, in the region of the pivoting movement BS, pivoting can take place along the contact surface 42 facing the working surface H and thus the contact surface 40, as a result of which the adhesive part 63 comes into contact with the working surface H and finally the holding element 60 is supported with its longitudinal end part 62, which is arranged at the other longitudinal end of the adhesive element 60 opposite the longitudinal end part 61, at the other longitudinal end of the holding element receptacle 55 in a form-fitting manner. Then, the holding element 60 is swung into and inserted into the holding element receptacle 55.

Furthermore, the recess 84 of the carrier body 80 makes it possible for the holding element 60 to roll down onto the running surface H within a range of rolling or winding movements. When the adhering portion 63 is rolled onto the working surface H, as it were, so that the adhering face 71 adheres at the working surface H, for example, the longitudinal end portion 61 has already been received in the holding-element receiving portion 55 and supported at the longitudinal end side 57 of the same holding-element receiving portion in the assembly technique.

Other possibilities for fastening the holding element 60 to the working surface H are provided, for example, by the holding element 60 being brought into abutment with its longitudinal end sections 61, 62 at the longitudinal end side 57 of the holding element receptacle 55, wherein the adhesive portion 63 is first of all arched away from the abutment surface 62 and the working surface H, i.e. the adhesive surface 71 runs arcuately above the working surface H and thus does not adhere thereto (see, for example, fig. 5).

Then, the holding element 60, in particular the intermediate section or the adhesive portion 63 thereof, is acted upon with a pressing force BP, that is to say pressed against the upper side 82, so that the holding element 60 is deformed in the direction of the working surface H and the adhesive surface 71 adheres to the working surface H.

For example, the operator presses the holding element 60, in particular with a finger or a tool, with a pressing force BP onto the upper side 82, which for that matter exhibits or has a control handle 93, in order to adjust the holding element from the positioning state PZ into the adhering state HZ.

Furthermore, it is possible for the holding element 60 to be partially or completely inserted into the holding element receptacle 55, but there is no contact of the adhesive surface 71 of the adhesive means 70 with the working surface H, i.e. there is a distance d between these two surfaces. For example, the holding element 60 can also be accommodated in the holding element receptacle 55 so as to be displaceable in the direction of the contact surface 42 or the working surface H when it has been inserted into the holding element receptacle 55. By means of the pressing pressure or pressing force BP onto the upper side 82 of the holding element 60, the adhesive surface 71 is adjusted in the direction of the contact surface 42 or the working surface H, so that the holding element 60 adheres to the working surface H. In this case, it is also possible for the holding element 60 to be either flexurally flexible as in the present exemplary embodiment or else flexurally rigid, i.e. for example the carrier body 80 does not have a recess 84 and/or is flexurally rigid.

For example, the carrier body 80 has a schematically indicated reinforcement 92. The reinforcement 92, for example a reinforcement rib, extends, for example, in the longitudinal extension of the carrier body 80. The carrier body 80 is preferably flexurally rigid transversely to the plug-in axis SB, with which it can be inserted into the holding element receptacle 55 or the plug-in receptacle 55A. In any case, the previously mentioned plug-in mounting for adjusting the holding element 60 or the adhesive surface 71 with respect to the holding element receptacle 55 from the positioning state PZ into the adhesive state HZ is possible by means of the holding element 60 being flexurally rigid and flexurally flexible.

However, it is also possible for the flexurally flexible or also flexurally rigid holding element 60 (the carrier body of which, for example, has a reinforcement 92 or is plate-shaped) to be pivotable about a pivot axis SC into the holding element receptacle 55, as illustrated in fig. 2, in order to bring it from the retaining state PZ into the adhering state HZ.

Furthermore, it is possible to provide latching or supporting contours 64 (shown schematically) on the holding element 60, in particular on the sides of the holding element 60 which face one another, which are supported for holding the holding element 60 in the positioned state PZ on the abutment contours 58A, for example the inclined sections 58, of the holding element receptacle 55 and which, by force loading with a pressing or pressing force BP, move past the abutment contours 58A in order to thereby adjust the holding element 60 or the adhesive means 70 into the adhering state HZ. For example, a latching projection which projects laterally beyond the outer circumferential contour of the carrier body 80 between the adhesive surface 71 and the hook-shaped projection 87 and which is supported in the positioning state PZ at the inclined section 58 and thus at the abutment contour 58A of the holding element receiver 55 and then slides past the inclined section 58 when the holding element 60 is adjusted further in the direction of the adhesion state HZ can be provided as a support contour 64.

Instead of the holding element 60, however, a holding element 160 can also be arranged in the holding element receptacle 55. The retaining element 160 and the abutment 40 form the system 10B.

The holding element 160 has a carrier body 180 which, like the carrier body 80, has supporting projections 85 arranged in rows at its longitudinal sides. In other words, the carrier body 180 can thus also be inserted into the holding element receptacle 55, wherein its support projection 85 can be supported on the upper side 43 of the contact body 40. However, the holding element 160 does not have an adhesive means 70 (wherein this would be possible without problems), but rather has through openings 170, for example 3 through openings 170 through which nails or similar other fixing pins are punched, which penetrate into the working surface H. The through-openings 170 are arranged next to one another in a row and extend, for example, in the region of the central holding section 163 of the holding element 160, over a length approximately corresponding to the adhesive section 63. The through-opening 170 extends from the upper side 82 to the lower side of the carrier body 180. It is obvious that the through-opening can also extend through an adhesive means, for example an adhesive layer, which can alternatively or additionally be arranged at the underside of the carrier body 180.

In the system 10C, a holding element 260, which has a carrier body 280 that substantially corresponds to the carrier body 80, is releasably fastened to the already explained abutment body 40, i.e. to the guide rail 41. That is, the carrier body 280 has the already explained support projections 85 on its longitudinal sides, so that it can be supported in a form-fitting manner on the holding element receivers 55. Thus, the holding element 260 can be inserted into the holding element receptacle 55 instead of the holding element 60 or 160 and then supported at least its longitudinal side 266 at the longitudinal side 56 of the holding element receptacle 55. Advantageously, the longitudinal end sections 261, 262 of the holding element 260 are likewise supported at the longitudinal end side 57 of the holding element receptacle 55.

At the underside 83 of the carrier body 280 there is a suction head 271 as an adhesive means 270. The suction heads 271 are arranged one after the other or adjacent to each other in rows extending, for example, parallel to the longitudinal sides 66. The suction head 271 is used to suck at the work surface H. When the holding element 260 is inserted into the holding element receptacle 55, i.e. from the upper side 43 of the abutment 40, the suction head 271 comes into adhering or suction contact with the working surface H, so that it fixes the guide rail 41 or the abutment 40 at least in the direction of movement transversely to the working surface H.

In this way, at least the support surface 88 of the carrier body 280 bears laterally against the wall surface 59 of the holding element receiver 55. Preferably, however, a hook-like projection 87 is present at the carrier body 280, which hook-like projection bears against the upper side 43 of the abutment body 40.

The carrier body 280 is flexurally flexible like the carrier body 80 and has recesses 84, for example, between the support projections 85, which facilitate the winding or rolling movement. Without any problem, transverse reinforcements not shown in the drawings can be provided at the carrier body 280 in the type of transverse reinforcement 81.

It is clear that retaining elements of the type of retaining elements 60, 160, 260 can be fastened not only to curved rigid abutments or guide rails, but also, for example, to curved flexible guide rails 141, which represent the abutments 140 of the system 10D.

The guide rail 141 has, for example, an abutment surface 42 for bearing or abutting against the work surface H and has an upper side 143 opposite the abutment surface 42, which is suitable as a sliding surface for, for example, the machine tool 20. For its longitudinal guidance, a profile contour 148 is arranged on the upper side 143, which performs the function of the guide contour 48, i.e. can be engaged in the guide receptacle 25 of the machine tool 20. The guide contour 48 is realized, for example, by a guide rib which projects or is higher than the guide rib upstream of the upper side 143 and which, unlike the illustration shown in the figures, can also have a recess or slit of the type of the recess 84 of the carrier body 80, so that the rolling up or rolling up of the body 140 onto the winding element 151 is easier. Said recess extends, for example, from the free end region of the guide contour 148 in the direction of the upper side 143.

The guide profile 148 extends parallel to the longitudinal sides 144, 145 of the abutment body 140. Advantageously, the guide contour 148 also extends from one end side 146 of the abutment 40 to the other end side 146, i.e. over the entire longitudinal length of the abutment.

The contact body 140 has a raised strip or raised contour 147, which is designed in the manner of a friction strip, for example a plurality of raised contours 147 running parallel to its longitudinal extent. The arching profile 147 extends parallel to the longitudinal sides 144, 145. When the abutment is rolled up on the winding element 151, the arching profile 147 loses its arching transversely to the longitudinal extension of the abutment 140. Thereby, the winding member 151 is stabilized.

Although the abutment 140 provides optimum longitudinal guidance at the machine tool 20, it is relatively thin and light, which can lead to slippage at the working surface H even when a slip-inhibiting lining made of rubber or the like is provided on the underside of the abutment, i.e. at the abutment face 42. In this case, it is advantageous if the contact body 140 also has a holding element receiver 55 or a plurality of holding element receivers 55 for one of the holding elements 60, 160, 260.

In the state of assembly at the respective abutment 40, 140, i.e. when it is received in the respective retaining element receiver 55 and occupies the positioning state PZ, the retaining element 60, 160, 260 does not project or only projects so far in front of the guide face of the respective abutment 40, 140 that the longitudinal movement of the tool machine 20 or of the guide element 21 along the longitudinal extension L is not impeded. For example, the holding elements 60, 160, 260 are accommodated in the holding element receptacles 55, but do not project beyond the guide surface 54A relative to the contact surface 42.

The holding element 60, 160, 260 holds the contact body 40, 140 by means of a supporting force component SK directed in the direction of the contact surface 42 in the sense of holding the contact body 40, 140 at the working surface H.

The holding elements 60, 160, 260 hold the bearing bodies 40, 140 against the working surface H by means of a transverse force component SQ transverse to their longitudinal extension L and a transverse force component SQ2 parallel to their longitudinal extension L. By means of the transverse force components SQ, SQ2, the contact body 40, 140 is fixed against shearing movements transversely to the working plane H. It is to be understood that a holding against shear forces only, i.e. one or both of the transverse force components SQ, SQ2, can already be sufficient, i.e. a holding of the respective abutment 40, 140 by the holding element 60, 160, 260 by means of the supporting force component SK is advantageous, but not absolutely necessary. Only the fastening of the contact body 40, 140 parallel to the working surface H already presents a particularly great advantage.

In the embodiments described so far, the abutment body has been described as being implemented as a separate component from the machine tool or another object to be guided or supported. However, it is also possible for the abutment body or the guide body to form part of the machine tool, as will become clear later. It is particularly advantageous if such a machine tool is temporarily fixed by means of the holding element according to the invention at the work surface to be machined, in order to achieve optimum machining of the workpiece.

The tool machine 320, which is designed as a top milling cutter, for example, has an abutment 340, which is shaped like a table or a foot. The contact body 340 can be lowered with its underside forming the contact surface 342 onto a base, for example a workpiece W. On its upper side 343 facing away from the contact surface 342, the contact body 340 has a machine support 348. A drive unit 322 is mounted in a longitudinally displaceable manner on the machine support 348. The machine support 348 comprises, for example, a plurality of guide rods 349 which engage longitudinally displaceably into the guide receptacles 325 of the drive unit 322. The drive unit 322 has a drive 323 for a working tool 324. The working tool 324 is, for example, a milling head, a drill or the like. The drive unit 322 can be gripped by an operator, for example at the handles 326, 327, in order to adjust the work tool 324 in a direction toward or away from the work surface H by means of the machine support 348 (corresponding to the arrow direction LH).

The holding element receptacle 55 is arranged on the abutment 340. For example, the abutment 340 has a lateral section 344, at which the holding element receiver 55 is arranged. That is, the operator can first position the abutment 340 on the work surface H and then temporarily fix it with respect to the work surface H by means of one of the holding elements 60, 160, 260 for machining the work surface H or the workpiece W, for example by the already explained method of mounting the holding elements 60, 160, 260 on the abutment.

It is also possible without problems to provide a further holding element receptacle of the type holding element receptacle 55 at the abutment 340 or at a further section of the type of section 344 to be provided at the abutment.

As in the exemplary embodiments explained below, a longitudinal guide or insertion opening can also be provided in the machine tool or its support or guide body, into which one of the holder elements 60, 160, 260 can be inserted in a direction of movement parallel to its adhesive surface 71.

The holding element 60, 160, 260 can also be used at the abutment, which can be used independently of the machine tool, but can also be used in conjunction with the machine tool:

the contact body 440 has, for example, a holding element receiver 455. The holding element receiver 455 is arranged, for example, in the region of the contact surface 442 of the contact body 440.

The abutment 440 can be used, for example, with a manually actuable tool, in particular a cutting tool. The abutment 440 can thus be a guide, for example.

The abutment 440 has a base leg 444 from which side legs 445, 446 project in a U-shape. The retaining element receiver 455 is arranged on the base leg 444 on its underside facing away from the side legs 445, 446. The upper side 443 of the base leg 444 extends between the side legs 445, 446 and forms, as it were, a deeper bottom between the side legs 445, 446.

Support feet 447 project laterally from the side legs 446. The support leg 447 and the base leg 444 preferably run parallel to each other. The side legs 446 and support legs 447 are stepped with respect to the base leg 444.

The side leg 446 has a support surface 448 on its side facing away from the base leg 444. The support foot 447 has a support face 449 at its side facing the side foot 446. The bearing surfaces 448, 449 are angled relative to one another. When the contact surface 442 lies flat on the work surface H, a receptacle is formed between the support foot 447 and the side foot 446, into which a workpiece W2 can engage, for example, which is then supported on the contact body 440. The support feet 447 then form, for example, a hold-down. Instead of the workpiece W2, it is also obvious that further abutments, for example the abutment 340 of the tool machine 320, can be engaged into the aforementioned receptacle and/or held by the abutment 340.

The side of the side leg 445 facing away from the base leg 444 can also serve as a support and provide a support surface 450, for example.

Further, the U-shaped accommodation portion restricted by the base leg 444 and the side legs 445, 446 can serve as a support accommodation portion.

The holding member accommodating portion 455 has wall surfaces 459 at its longitudinal sides, however, is open at its longitudinal end 457. Between the walls 459, a base 456 of the holding element receiver 455 extends, on which the support lug 85 can be supported with its free end, that is to say with its longitudinal end furthest away from the underside 83 of the carrier body 80. The hook-shaped projection 87 of the holding element 60 forms a guide projection which engages into the guide receptacle 458 of the holding element receptacle 455. The guide receptacle 458 extends over the entire length of the retaining element receptacle 455, that is to say from one longitudinal end 457 to the other longitudinal end 457, but can also be shorter. In any case, the guide receivers 458, which extend from the base 456 of the holding element receiver 55 into the wall 459, form a cutout or rear gripping surface or have a rear gripping surface 495, at which the hook-like projections 87 are supported, which for this matter form a rear gripping contour 491. The hook-shaped projection 87 then holds the abutment 440 with a supporting force component SK directed in the direction of the abutment surface 442 in the sense of holding the abutment 440 at the working surface H.

The mounting of the contact body 440 on the holding element 60 can take place, for example, in such a way that the holding element is first glued to the working surface H and then the contact body 440 is pushed with its longitudinal guide, the holding element receptacle 455, parallel to the working surface H or the contact surface 442 onto the holding element 60, for example, in accordance with the displacement axis SA.

However, it is also possible for the contact body 440 to be positioned with the holding element 60 already accommodated in the holding element receptacle 455 at the working surface H, wherein first of all the adhesive surface 71 is also spaced apart from the working surface H and is remote therefrom. By way of example, the clearance of the hook-shaped projection 87 in the guide receptacle 458, it is possible for the adhesive surface 71 to be brought into contact with the work surface H by pressing on the base leg 444 with the aid of a force or pressing force BP, so that the abutment 440 is fixed on the work surface H.

The abutment body 440 is also suitable for supporting a workpiece, for example, to be mounted on a wall, i.e., as an assembly aid, the abutment body 440 is first fixed to the wall (i.e., the working surface H) and then the workpiece, for example, a picture to be hung, can be supported on one of its support surfaces. In addition, additional fastening contours can also be provided for the abutment body according to the invention, whereby, for example, schematically illustrated hooks 401 are provided.

The concept of the rear gripping contour and the rear gripping surface and the recess to achieve the winding or rolling of the holding element can also be achieved in other ways, which will become clear from the embodiments explained later.

The schematically illustrated abutment body 540 can be designed, for example, as a guide element of a machine tool or for a machine tool, similar to the abutment body 40. The bearing body 540 has, for example, longitudinal sides 544, 545 which extend between the end sides 546 of the bearing body. The upper side 543 of the abutment 540 can, for example, represent a sliding surface for a tool machine, a base for a machine support 348 or the like. At the lower side opposite the upper side 543, an abutment surface 542 is provided for example for placing on a work surface H. A sliding-resistant lining or the like can be provided on the underside or the contact surface 542, wherein preferably the fixed retention at the working surface H is or can be achieved by means of a retaining element 560.

In the region of the contact surface 542, the contact body 540 has a retaining element receptacle 555 for a retaining element 560. The holding element 560 has a carrier body 580, on the underside 583 of which an adhesive means 570 is arranged, which has an adhesive surface 571, for example an adhesive surface and/or a suction surface corresponding to the adhesive means 70, 270, whereby the holding element 560 can be adhered at the working surface H.

The holding element 560 can be inserted into the holding element receptacle 555 along the plug axis SA, i.e. forms a plug-in body. The retaining element receptacle 555 forms a longitudinal guide about the plug axis SA for the retaining element 560.

The retaining element 560 has a support surface 588 on its longitudinal side 566, which is adapted to lie flat against a wall surface 559 of the retaining element receptacle 555. The wall surface 559 and the support surface 588 run transversely to the plug axis SA, preferably at right angles to the adhesive surface 571. In other words, the abutment 540 is supported on the holding element 560 with respect to forces which are transverse to the plug axis a and parallel to the adhesive surface 571 or the abutment surface 542.

Furthermore, the holding element 560 is supported with the upper side 582 of the carrier body 580 at the bottom 558 of the holding element receptacle 555.

Although the carrier body 580 itself has a block-like shape, it is flexurally flexible. For this purpose, a recess 584 is provided on the carrier body 580, which extends transversely to the plug axis direction SA and thus makes a bending possible in the sense of a rolling or rolling movement of the carrier body 580.

With regard to the force direction which runs at an angle, for example at right angles, to the adhesive surface 571 or the contact surface 542, a support is provided by means of a positive-locking contour 590 which is designed as a dovetail contour. For example, the carrier body 580 has a dovetail positive contour at its upper side 582, i.e. the support projections 585 or the support projections 585 arranged in rows, which extend parallel to the plug axis SA, since the carrier body 580 is divided by the recesses 584.

The form-fitting contour 590 or the support projections 585 has a rear grip contour 591, i.e. an inclined surface, which extends obliquely between the upper side 582 of the respective support projection 585 and an end side or upper side 586 parallel to the upper side 582. The rear gripping contour can be brought into a form-fitting receptacle 597 at the holding element receptacle 555 in abutment with the rear gripping surface 595. It is possible, but not necessary, for the upper side 586 to bear against the bottom 596 of the form-fitting receptacle 597. By the rear grip of the rear grip contour 591 and the rear grip surface 595, the contact body 540 is held at the holding element 560 by means of the supporting force component SK in the sense of holding the contact body 540 at the working surface H.

The form-fitting contour 590 can extend between its longitudinal end sides 567 over the entire length of the retaining element 560, but can also extend over only a part of said length.

The bearing body 640, like the bearing body 540, has a holding element receptacle 655 which extends parallel to its longitudinal sides 644, 645. The retaining element receiver 655 has a wall surface 659 extending parallel to the longitudinal extent LE of the contact body 540 or parallel to the longitudinal sides 644, 645, and a bottom surface 658. In the region of the bottom face 658, a form-fitting receptacle 597 can be present, so that a holding element, for example of the type of a holding element 560, can be held in a form-fitting manner in the holding element receptacle 655.

The retaining element receiver 655 can extend over the entire length of the contact body 640, i.e. between its longitudinal end sides 646. However, it is also possible for the retaining element receiver 655 (likewise the retaining element receiver 555) to be designed in the manner of a blind hole, i.e. to have a base or end stop with respect to the plug axis SA.

The holding member accommodating portion 655 serves to accommodate the holding member 660 or 760. The holding elements 660, 760 have adhesive means 670, 770 with an adhesive surface 671, 771, for example an adhesive surface. The adhesion surfaces 671, 771 can extend over the entire length of the respective holding element 660, 760, that is to say between the mutually opposite longitudinal end sides 667, 767 or can also extend over only a part thereof.

At the longitudinal sides 666, 766 of the carrier bodies 680, 780 of the holding elements 660, 760, rear gripping contours 691, 791 are formed, for example inclined faces, which can be brought into rear gripping with the inclined wall surfaces 659 of the holding element receptacles 655. The bearing body 640 is thereby held at the respective holding element 660, 760 with a supporting force component SK transverse to the plug axis SA.

Recesses 684, 784 can be provided at the carrier bodies 680, 780, for example.

When the carrier body 680 is a solid, block-shaped carrier body, as it were, the carrier body 780 has a base foot 781 from which lateral feet and thus supporting projections 785 project laterally. The outer side or exterior face facing away from the base leg 781 forms a rear gripping contour 791.

The abutments 540 and 640 are preferably flexurally flexible at least in the region of their retaining element receptacles 555, 655, the contact body can be deformed in the direction of the working surface H and/or the contact surfaces 542, 642 by a contact pressure BP acting on its upper sides 543, 643 in the region of the retaining element receptacles 555, 655, so that the adhesive means 570, 670, 770 of the holding elements 560, 660, 760 can be adjusted from the positioning state PZ into the adhesive state HZ, in the positioned state, the adhesive means 570, 670, 770 and/or its adhesive surfaces 571, 671, 771 are retracted behind the abutment surfaces 542, 642 and/or are at a distance from the working surface H, in the adhesion state, the adhesion means 570, 670, 770 and/or its adhesion surfaces 571, 671, 771 are aligned with or project beyond the contact surfaces 542, 642 and/or are in fixed or adhesive contact with the working surface H. The abutments 540 and 640 are flexible, for example, because their material is flexurally flexible and/or have deformation recesses 547, 647, such as grooves, slits or the like, which facilitate or facilitate deformability or flexibility.

Like the abutment 40, the abutment 840 is designed as a guide rail 41. The basic design of the contour of the guide rail 41, and thus, for example, the profile body 50, the supporting element 49, the guide projection 48A and the guide contour 48, is the same in the case of the abutment 840 as in the case of the abutment 40.

Thus, the contact body 840 can be adhered to the work surface H with a friction fit when it is lying on the work surface H, but can nevertheless be displaced along the work surface H. In order to achieve a releasable retention of the abutment 840 at the working surface H in the case described, retaining elements 860, 960 are provided.

The holding element 860 comprises, for example, a fastening portion 861, which can be detachably connected to the abutment 840 in a form-fitting manner. For example, the fastening part 861 comprises a particularly plate-shaped carrier 862, which can be connected to the abutment 840 by means of a clamping mechanism 890. The clamping mechanism 890 comprises a clamping body 891 which can be positioned, for example, in the receptacle 51 at different longitudinal positions with respect to the longitudinal extension L of the abutment 840. The clamping body 891 is designed, for example, in the form of a slider which can be inserted into a groove-shaped or slot-shaped receptacle 51 and can be clamped in the receptacle 51 by means of a clamping screw fastening 892. Then, the securing portion 861 is secured at the abutment 840 with respect to the longitudinal extension L. It is clear that the fastening part 861 and therefore the holding element 860 can also be mounted on the abutment 40 by means of the clamping mechanism 890.

The carrier 862 has a bearing mechanism 866, by means of which the carrier body 880 is pivotably supported about the carrier 862 and thus about the bearing body 840 about the pivot axis SW in order to adjust the adhesive means 870 arranged at the carrier body 880 from a position state PZ, in which the bearing body 840 is displaceable at the working surface H despite a frictional fit between the bearing element 49 and the working surface H, into an adhesive state HZ, in which the adhesive means 870 adheres with its adhesive surface 871, for example comprising an adhesive or suction surface, to the working surface H and thus fixes the holding element 860 and ultimately the bearing body 840 with respect to the working surface H.

The carrier body 880 is preferably plate-shaped and has a support section 885 and a grip section 886, between which an adhesive portion 863 is present. The support section 885 has, for example, a support projection or support bracket for supporting the mechanism 866. At the grip section 886, the carrier body 880 can be gripped by an operator.

At the grip section 886 there is a latching profile 887 for latching with a latching counterpart profile 888 at the carrier 862. The detent profile 887 can latch with the detent counter profile 888 when adjusted from the detent state PZ into the adhered state HZ. In this case, it is possible that, in the latched state, the adhesive surface 861 arranged on the underside 883 of the carrier body 880 has already reached contact with the working surface H and thus secures the carrier body 880 and ultimately the contact body 840 on the working surface H. However, it is also possible that in a position in which the carrier body 880 has latched with the fastening part 861, there is still a distance between the adhesion surface 871 and the working surface H, i.e. the adhesion surface 871 is retracted with respect to the working surface H behind the contact surface 42. By pressing or pressing force BP, for example with fingers, onto the upper side 882 of the carrier body 880, the carrier body 880 is arched in the direction of the contact surface 42 and thus in the direction of the working surface H, as a result of which the adhesive means 870 can come into contact at the working surface H.

The detachment process of the adhesive means 870 from the work surface H is achieved simply by the operator grasping the carrier body 880 at the grasping section 886, which can also be referred to as a pendulum or pendulum position, whereby on the one hand the detent profile 887 comes out of engagement with the detent counter profile 888, but on the other hand the carrier body 880 pulls the adhesive means 870 from the work surface H, as it were, in a detachment movement. In this case, it is possible for the carrier body 880 to be able to be flexibly deformed in a bending manner in addition to the pivoting movement, so that the different sections of the adhesion surface 971 can be removed from the working surface H gradually or continuously.

Through openings 872 are preferably also provided at the carrier 862 for nails, threaded fasteners or similar other fixing pins for directly fixing the fixing portion 861 at the work surface H.

The retaining element 860 can be covered by a cover as with the retaining element 60, for example as is the case in the retaining elements 960A, 960B and 960C explained below.

It is also possible for the adhesive means 970 applied in the holding elements 960A and 960B to be used, for example, at the carrier 80 of the holding element 60.

The holding elements 960A, 960B can be directly bonded to the contact bodies 40, 140 or 840, for example, glued to the underside 52 of the profile body 50, in particular in the intermediate space between the support elements 49, in which the contact surface 42 projects in front of the underside 52 and thus, when the contact bodies 40, 840 lie on the working surface H, there is a distance between the contact bodies 40, 840 and the working surface H. The holding elements 960A, 960B can also be used without problems at the other illustrated abutments 340, 440, 540, 640, for which the adhesive surface 973 explained below is suitable.

The adhesion means 970 holding the elements 960A, 960B is double-sided adhesive. The adhesive means has an adhesive surface 971 for adhering to the working surface H and an adhesive surface 973 on its opposite side for adhering to another body, for example directly to the contact body 40, 140, 840 or, in the case of the holding element 960A, the carrier body 980A. The adhesion means 970 of the holding element 960A can also be adhered directly to the underside 52 of the abutments 40, 840.

The carrier body 980A can be inserted with a form fit into the holding element receiver 855A of the abutment body 840. The long and narrow sides thereof correspond to the support surfaces 88 of the carrier body 80 and lie against the wall surfaces of the holding element holder 855A when the carrier body 980A is inserted into the holding element holder 855A, which is designed as a plug-in holder. In particular, the longitudinal side 966 of the carrier body 980A bears with a form fit against the inner longitudinal side of the holding element receiver 855A. Furthermore, a longitudinal end side 967 of the carrier body 980A bears in a form-fitting manner against a longitudinal end side or a longitudinal end region of the holding element receiver 855. In other words, the contact body 840 is supported with its holding element receiver 855A on the carrier body 980A and thus on the holding element 960A in a force direction parallel to the contact surface 42 or the adhesive surface 971.

However, at the longitudinal end region of the carrier body 980A there is a recess 981, by means of which the handling section 992 of the cover 990A of the holding element 960A and the processing section 972 of the attachment means 970 project from the underside 983 to the upper side 982 of the carrier body 980A and can be grasped by an operator.

However, it is also possible in principle for carrier body 980A to be shorter than the longitudinal extension of holding element holder 855A, so that recesses 856A are present at their longitudinal end regions, by means of which actuating section 992 and/or treatment section 972 can project from the underside of abutment 40 to its upper side 43.

In the holding element 960B, it can be said that the adhesion means 970 itself forms its carrier body 980B. The adhesive portion 973 can be realized directly by the contact body 40, 840.

Preferably, the holding element 960B is adhesively bonded to the abutments 40, 840 in such a way that its handling section 972 and the handling section 992 project from the underside of the abutments 40, 840 to the upper side 43 before projecting laterally to the abutments 40, 840 or through the recess 856B. The recess 856B is preferably designed in the form of a window and/or as a through-opening, for example, which extends from the underside of the abutment 40, 840 to the upper side 43.

The height of the retaining elements 960A, 960B in the fixed state on the abutments 40, 840 is preferably measured such that the adhesive surface 971 of the adhesive means 970 of the retaining elements is aligned with the abutment surface 42 of the abutments 40, 840, for example.

In the positioning state PZ, the adhesion surface 971 is covered by the covering section 991 of the covering portions 990A, 990B of the holding members 960A, 960B. The cover portions 990A, 990B are preferably film-shaped and can be, as it were, removed from the adhesive surface 971, so that the adhesive surface 971 and thus the holding members 960A, 960B can be switched from the positioning state PZ into the holding state or the adhering state HZ.

At the cover section 991, a handling section 992 is articulated via a reversing section 993, the free end region of which forms a grip section 994. The cover portions 990A, 990B can now be lifted off or lowered from the adhesive surface 971 by a pulling operation (indicated by an arrow in fig. 27 and 29) of the gripping section 994, in the manner of a stripping movement. Thereby, the adhesion surface 971 is released and can adhere at the working surface H.

It is possible that after removal of the cover portions 990A, 990B, there is also a gap between the adhesion surface 971 and the working surface H. By means of a corresponding pressing action with the aid of the pressing force BP, for example, on the carrier body 980A or on the sections of the abutments 40, 840 in which the holding elements 960A, 960B are arranged, the adhesive surface 971 can be brought into adhesive contact with the working surface H.

The removal of the retaining elements 960A, 960B from the adhered state HZ is also possible without problems in the case of abutments 40, 840 lying on the working surface H. I.e. the adhesion means 970, has a treatment section 972 which can be grasped by an operator in order to stretch the adhesion means 970, whereby the adhesion of the adhesion surface 871 to the working surface H forming the abutment surface is eliminated, whereby the retaining elements 960A, 960B are detached, as it were, from the working surface H. The abutment 40, 840 is then free to move relative to the working surface H.

The treatment section 972 and the handling section 992 are arranged at opposite longitudinal end regions to each other in the case of the holding element 960A, and at the same longitudinal end region in the case of the holding element 960B. Here, it is advantageous that the handling section 992 of the cover portion 990B projects ahead of the processing section 972, so that it can be gripped relatively easily. This is due to the fact that (geschult) the cover 990B does first have to be removed by means of the actuating section 992 before the retaining element 960B is then deactivated, as it were, by actuating the treatment section 972.
