Technical Field

The invention relates to an anchor fitting for anchoring in a workpiece, wherein the anchor fitting has a tie rod for arrangement in a connection recess of the workpiece and a support body for arrangement in a support recess of the workpiece, which is in communication with the connection recess, wherein the support body has a plug receptacle for insertion of a plug section of the tie rod along a plug axis and a support surface arrangement for support at the support recess of the workpiece, wherein at least one support surface of the support surface arrangement extends in particular substantially orthogonally, transversely to a longitudinal axis of the tie rod inserted into the plug receptacle, so that the tie rod is supported about its longitudinal axis at the support recess, wherein the anchor fitting has a clamping body for clamping the plug section of the tie rod in the plug receptacle, and wherein at least one support body of the anchor fitting has a flat profile with flat sides lying opposite one another and a narrow side extending between the flat sides, in particular rounded, for at least partially positive support in a connecting or support recess of the workpiece.

Background

Such an anchoring fitting is explained, for example, in DE 102015100199 a 1. Such an anchoring fitting relates to a connecting fitting for connecting two workpieces, for example furniture parts. The tie rod has a rod-shaped outer shape and thus extends along a longitudinal axis and can be inserted into the holder body. The support body has a flat shape and can be inserted in a rotationally fixed manner into the corresponding support recess. The tie rod is typically encased in a support body which has a flat profile which in principle geometrically corresponds to the profile of the support body, so that a robust, torsion-proof and substantially immovable fitting construction for accommodation in the two workpiece recesses (i.e. the connecting recess and the support recess) is obtained.

However, the machining must be carried out very precisely, so that the anchor fitting or the connection fitting actually fits into the workpiece recess and the counterpart (i.e. the other workpiece) can be connected accordingly.

DE 102009011845 a1 discloses a connection fitting with an anchor assembly and a tension element and a retaining body, which is joined to a first and a second section at the inner periphery of a first and a second receptacle to form a connecting workpiece.

DE 102006024265B 3 describes an accessory device for connecting two furniture parts by means of a tensioning means, which comprises a tensioning bolt and a tensioning element, which is mounted movably for the purpose of performing a tensioning movement in an accessory part of the accessory device, which accessory part has a plug-in recess for inserting the tensioning bolt.

DE 9490402U 1 describes a mechanism with a female part and a male part having an end section with an extension area for accommodation in the female part, wherein the extension area contains a plurality of conical sections for spreading apart the female part.

Disclosure of Invention

Starting from this, the object of the invention is to provide an improved anchor fitting.

In order to solve this problem, in an anchoring fitting of the type mentioned at the outset, it is provided that the plug receptacle, transversely to the plug axis, has an orientation transverse width which is suitable for the orientation of the tension rod with respect to the bearing body and which is greater than the movement play which is necessary for inserting the tension rod into the plug receptacle.

The movement play is essentially the distance between the plug receptacle and the plug section of the tie rod, which is required for the substantial insertion of the plug section into the plug receptacle. The movement gap is a clear span between the plug receptacle and the plug section of the tie rod, which is required for inserting the plug section into the plug receptacle. The transverse width of the plug receptacle must therefore be sufficient anyway to enable the plug section of the tie rod to be inserted into the plug receptacle.

The basic concept of the invention is as follows: the tie rod can be inserted into the support body in a manner known per se, but with a play of movement there which is greater than that which is necessary for inserting the tie rod into the plug receptacle. The tie rod can be oriented in the plug receptacle, so that, if appropriate, inaccurately arranged workpiece recesses, for example, holes for forming the connection recesses and/or the bearing recesses, are not critical. But also for the orientation of the two workpieces, i.e. the workpiece accommodating the anchoring fitting and the workpiece which can be fixed at the first workpiece by means of the anchoring fitting, not to the same extent as in the case of the prior art.

At least one support surface of the support surface arrangement extends transversely to the longitudinal axis of the tension rod inserted into the plug receptacle, for example orthogonally or approximately orthogonally, in particular at an angle of approximately 80 ° -100 °, preferably 85 ° -95 °.

Preferably, the oriented transverse width is at least 5%, preferably approximately 10% or even further preferably approximately 20-30% greater than the transverse width of the plug section of the tie rod. The clear span of the plug receptacle is therefore so large that the tie rod remains adjustable over a wide range with its plug section transverse to its longitudinal axis.

Expediently, the plug receptacle has a transverse height, in particular orthogonal, which is angled, in particular orthogonal, with respect to the longitudinal axis of the tie rod, transversely, in particular orthogonally, to its oriented transverse width. The ratio of the transverse height to the height of the plug-in section of the tie rod (which plug-in section fills or extends within the transverse height, as it were) is expediently smaller than the ratio of the oriented transverse width to the transverse width of the plug-in section of the tie rod. The transverse height expediently has a movement play which is sufficient for inserting the tie rod into the plug receptacle. The movement play is expediently approximately 1 to 5% of the height of the plug-in section of the tie rod. The transverse height extends, for example, between a base surface and a support surface opposite the base surface or a pair of support surfaces of the plug receptacle opposite the base surface.

One or more parts of the anchor fitting, in particular the support body and the tie rod and, expediently, the clamping body, are expediently composed of metal. However, it is also possible for one or more parts of the anchoring fitting to consist of plastic, in particular of a polyamide material or the like.

The clamping body is expediently adjustable with respect to the holder body along a clamping axis, wherein the orientation transverse width extends transversely to the clamping axis. The clamping axis and the longitudinal axis of the tension rod preferably extend orthogonally or at least transversely to one another when the tension rod is inserted into the plug receptacle. Thus, the longitudinal extension of the plug axis, the clamping axis and the transverse width or the transverse width expediently runs orthogonally to one another. However, an oblique arrangement is also possible, i.e. for example the clamping axis runs obliquely to the plug-in axis. Furthermore, it is conceivable that the clamping is not carried out by only one clamping body, but by a plurality of clamping bodies.

The clamping body is expediently arranged opposite the bottom surface of the plug receptacle. The clamping body is thus adjusted toward the bottom surface, i.e. when it is intended to assume its clamping position in which it clamps the tension rod in the plug receptacle.

The plug receptacle expediently has a bottom surface which is provided for receiving a plug section of the tie rod. The bottom surface may be said to form a counter-pressure surface or abutment for the clamping body.

The bottom surface and/or the bearing of the plug section of the tie rod for bearing on the bottom surface is expediently a flat or planar surface. It is particularly advantageous if the support and the base of the plug section of the tie rod rest against each other in a surface-like and/or tilt-proof manner. However, it is also possible for the tie rod to have, for example, a concave bearing surface which can bear on a corresponding convex bottom surface of the plug receptacle or, however, can also bear on a flat or planar bottom surface of the plug receptacle.

The clamping body expediently has a clamping inclination, for example a clamping cone, on its side facing the plug-in section of the tie rod, for example on its end side.

The clamping body expediently comprises or is formed by a clamping screw fastening. It is also possible that the clamping body does not have to be a clamping screw fastening, but another body, which however has a screw section for screwing into the holder body. A screw bore or a screw through-opening is expediently provided at the bearing body, which extends at an angle, in particular transversely or orthogonally, to the plug axis of the plug receptacle.

In addition, it is advantageous if the plug receptacle is wider than the base surface in the region between the clamping body and the base surface in order to provide the alignment transverse width. The plug receptacle thus has a relatively narrow bottom surface, but a raised portion or a plurality of raised portions is/are provided on the bottom surface or in the region between the bottom surface and the clamping body.

The plug receptacle expediently extends obliquely outward from the bottom face, for example in a curved manner, linearly or the like. The plug receptacle thus has a side wall surface which extends obliquely, in particular in a curved manner, outward from the bottom surface. It is possible that the plug receptacle has such a curved or obliquely extending side wall surface only on one side, while the opposite side wall surface can be, for example, inclined inwardly toward the bottom surface or orthogonal thereto.

The plug section of the tie rod expediently has a bearing surface for bearing on the base surface of the plug receptacle and at least one projection which projects in a plane parallel to the bearing surface and which projects in the direction of the orientation transverse width in front of the bearing surface. In this way, the tie rod is narrower in the region of the bearing surface than in the region of the at least one projection. The at least one projection can be formed, for example, by an actuating contour, for example an outer edge surface, for the assembly tool. It should be mentioned at this point that the plug section as a whole can be of polygonal, for example quadrangular, pentagonal, hexagonal or octagonal configuration. In this case, the bearing surface is formed on one of the surfaces between the edges.

The bearing surface arrangement of the bearing body expediently has at least two bearing surfaces which are arranged at mutually opposite sides and are provided for bearing at the bearing recess transversely, in particular substantially orthogonally, to the longitudinal axis of the tie rod. The support surface thus extends transversely to the longitudinal axis of the tie rod. The support surface can be a straight support surface or can be a planar support surface. Preferably, the support surface has a curved portion.

The support surface component of the support body expediently has at least one support rib and/or a rib structure for engaging into the workpiece in the region of the support recess. The support rib or the at least one support rib can penetrate into the workpiece, in particular a wood workpiece, for example, and an anti-rotation can be achieved there.

Furthermore, it is advantageous if the at least one support body has a support body receptacle for the support body, into which the support body engages in the assembled state of the anchor fitting. It should be mentioned at this point that the support body can form the support body, that is to say, for example, the support body itself has a flat profile with flat sides lying opposite one another and narrow sides extending between the flat sides, for example, rounded or straight.

It is also to be added that the flat side is wider, for example twice or three times wider, transverse to the longitudinal axis of the support body than the narrow side.

When the support body is a separate body from the support body, the support body has in an advantageous embodiment the previously mentioned support body receptacle. The support body receptacle can be, for example, a through-opening through which the support body can be plugged. Furthermore, it is possible that the support body receptacle is a blind hole or blind hole into which the support body can be inserted.

An embodiment is preferred in which the support body receptacle is provided between the fork-shaped projecting arm portions of the support body. The narrow side is suitably provided at an arm portion of the support body. The arm of the support body is rounded, in particular on the outside (that is to say away from the support body receptacle).

At least one arm of the support body, but for example also at both arms of the support body, a linear guide, for example a guide groove or a guide projection, is expediently provided for the introduction of the stand body into the stand body receptacle. At the support body itself there is a guide contour which cooperates with the linear guide, for example a guide projection for engaging into a guide groove or a guide receptacle for engaging or for receiving a guide projection of the arm. For example, the support body can be inserted transversely to an insertion axis of a support body already arranged in the support recess, by means of which the support body can be inserted into the support recess of the workpiece.

An anti-rotation contour, for example a polygonal anti-rotation contour, is expediently provided at the support body receptacle and/or the support body for the anti-rotation reception of the support body in the support body receptacle. In this way, the support body cannot twist when it is in the support body receptacle of the support body. This facilitates the handling of the clamping body, for example.

The support body receptacle is expediently arranged at least one flat side or extends between the flat sides of the support body. Thus, the support body can be inserted into the support body, for example from the flat side of the support body, or can be plugged through the support body.

In this connection, it is to be noted that the support body advantageously projects in front of the support body on at least one side, in particular a flat side, of the support body. Furthermore, it is expedient for the support body to project in front of the support body at mutually opposite sides, in particular flat sides, of the support body.

Furthermore, it is advantageous if the support body has a through-opening for the tie rod. The through-opening expediently has, at least in the region of the support body, a transverse width which enables the orientation of the tension rod in the plug receptacle. The lateral width can be substantially less than the directional lateral width. However, it is advantageous if the transverse width of the passage opening for the tie rod is greater than the oriented transverse width of the plug receptacle of the holder body.

The at least one support body is expediently provided or designed for arrangement in the connecting recess. The support body expediently has flat end faces. When the support body is inserted into the connecting recess and the anchor fitting is completely fitted, the flat end face can be aligned, for example, with the outer contour of the workpiece.

The tie rod expediently has at least one rotationally driving contour for the setting tool, for example a hexagonal contour or another polygonal contour. The rotational driving profile is suitable for use with a socket head wrench, for example. The rotational driving contour can be, for example, an inner contour. Preferably, the rotational driving profile comprises an outer peripheral profile of the pull rod. The assembly tool, for example a socket head wrench, an assembly nut, an assembly wrench or the like, can be brought into engagement with the rotational driving contour.

Preferably, as mentioned, the or a rotational driving profile is arranged at the outer periphery of the tie rod. Furthermore, it is preferred that the rotational driving contour is arranged in the region of the plug-in section. For example, an internal hexagon or other rotation-driving contour is provided on the end face of the longitudinal end at which the plug-in section is arranged or provided. The rotational driving contour can also be formed completely in the plug section or the plug section can be designed completely as a rotational driving contour at its outer periphery, in addition to the adjusting or tensioning or adjusting inclination explained below. The rotational driving contour can be provided, for example, for the plug-in section to be seated at least partially in a rotationally fixed manner in a plug-in receptacle of the support body.

An advantageous embodiment provides that the at least one rotational driving contour is arranged at the head or at the end face of the tie rod, in particular at the head at the end face.

An actuating recess for the at least one rotational driving contour is advantageously provided at the plug receptacle of the support body for the tie rod. By means of the actuating recess, the tie rod can be actuated when it is received in the plug receptacle, preferably at and/or from its end face, for example in the region of the pivot profile.

The plug receptacle of the support body for the tie rod is advantageously designed as a through-opening. The through-opening enables, for example, the manipulation of the rotational driving contour explained above.

The tie rod expediently has a helical section, for example for screwing into the anchor. The screw section and the plug section which can be inserted into the plug receptacle of the holder body are arranged at mutually opposite longitudinal end regions of the tie rod. Thus, one longitudinal end of the tie rod is provided for insertion into the holder body, and the other longitudinal end is provided for connection with a further body of the anchor fitting, for example an anchor body. However, the helical portion can also be provided for screwing into other workpieces. The helical section can, for example, have a thread cut in itself, which can be screwed directly into a workpiece, in particular a wood workpiece. Preferably, an inclined surface assembly is provided between the drawbar and the clamping body for longitudinally adjusting the drawbar with respect to the holder body in a direction of a longitudinal axis of the drawbar. The inclined surface arrangement can, for example, comprise or can be formed by the already mentioned clamping inclination, in particular the clamping cone, at the clamping body.

The inclined surface arrangement expediently comprises at least one adjusting inclined portion running obliquely to the longitudinal axis of the tie rod, which adjusting inclined portion is provided in particular at the tie rod itself, but can also be provided at the clamping body. It should be mentioned at this point that corresponding adjusting ramps or inclined surfaces can be provided at both, i.e. the tension rod and the clamping body. The at least one adjustment ramp can comprise a plurality of, for example two or three adjustment ramps which extend at an angle to one another in the sense of a deepening or a projection.

It should be mentioned at this point that the adjustment ramp arranged at the tie rod can be longer than the adjustment ramp arranged at the clamping body.

The inclined surface arrangement expediently extends transversely to the longitudinal axis of the tension rod with a transverse width which effects an orientation of the tension rod with respect to the support body in the region of the orientation transverse width of the plug receptacle. Thus, the adjustment ramp is not narrow along the longitudinal axis of the tie rod, but rather is relatively wide. The tie rod can be oriented within the plug receptacle, the engagement of the clamping body into the adjustment ramp of the tie rod being maintained at all times.

In this connection, it is preferred that the assembly is such that the inclined face at the tie rod is inclined only at an angle relative to the longitudinal axis of the tie rod, but not transverse thereto. However, it is also possible for the adjusting ramp or the ramp assembly to have at least one recess with a two-dimensionally extending ramp, for example a conical bore. Such a hole can be easily manufactured. Nevertheless, the holes are realized with corresponding flat, inclined portions transverse to the longitudinal axis of the tie rod: the tie rod remains able to be oriented within the plug receptacle in the region of the orientation transverse width.

In a preferred embodiment, the pull rod can be fixed in the plug receptacle by the clamping body in a form-fitting manner in the direction of the longitudinal axis of the pull rod or in the direction of the plug axis of the plug section in relation to the plug receptacle. Furthermore, it is advantageous if the pull rod can be fixed by the clamping body with a force fit with respect to the plug receptacle transversely to the longitudinal axis of the pull rod or transversely to the plug axis of the plug section. The tie rod can be additionally supported at the connecting recess, for example transversely to its longitudinal axis, by friction-fit abutment.

The abutment body is suitably arranged for anchoring the anchoring fitting in the first workpiece. The anchor fitting additionally comprises at least one retaining body, for example the already mentioned anchor body, into which a tie rod can be screwed for fixing in a retaining recess of the second workpiece. The holding body is connected, for example firmly connected, to the pull rod. However, the holding body can also be detachably connected to the pull rod by means of a fastening means. The fixing means for example comprise screw means and/or are formed by a screw connection. Furthermore, it is possible that the retaining body has a passage opening for at least one subsection of the tie rod. The tie rod can thus be inserted through the passage opening, for example, in a helical section, and connected to a further component, for example, a further tie rod.

The retaining body expediently has a flat profile with flat sides lying opposite one another and narrow sides extending between the flat sides, for at least partially positive support in the retaining recess, for example rounded. The retaining body expediently has an outer contour wrap which corresponds to the outer contour wrap of the at least one support body of the basic anchor fitting already explained. It should be mentioned at this point that the anchor fitting expediently has a part which can be inserted into the ring-shaped workpiece recess and which, in addition to the tie rod, otherwise has a body which has the aforementioned flat profile. The bodies with the outer peripheral geometry of the flat sides are expediently identical, so that all flat-profile recesses can be produced in the workpiece by means of a single drilling tool or a single adjustment of the drilling/milling tool.

However, the holding body can also be multi-part, for example two-part. The holding body can be inserted into the holding recess at the workpiece from two sides opposite to each other. The respective tie rod can be held, in particular releasably held, at the respective retaining body or at the retaining body portion.

The holding body expediently comprises a clamping body for clamping in a holding recess of the second workpiece or forms such a clamping body. As a result, the holding body can be fixed in the holding recess with a firm hold.

The holding body expediently has at least one gripper arm for clamping in a holding recess of the second workpiece. Particularly preferred are two gripper arms or a pair of gripper arms which are arranged at opposite sides and which can be clamped in a splayfoot-like manner (sprezfu beta atig) in the holding interspace. The at least one clamping arm or the pair of clamping arms can be adjusted, suitably by the tie rod itself or by a wedge which can be actuated via the tie rod, into a clamping position in which the holding body is clamped in the holding recess. The pull rod can be expediently inserted through the passage opening of the holding body and can be connected to the clamping body, for example can be screwed to the clamping body. When the pull rod is screwed on, for example by means of the rotational driving contour already mentioned, the pull rod adjusts the wedge between the base body of the holding body and the clamping arm or the two clamping arms in such a way that the clamping arm or the at least one clamping arm is spread apart from the base body of the holding body in order to clamp the holding body in the holding recess.

Furthermore, it is advantageous if the tie rod forms a first tie rod and the abutment body forms a first abutment body, and if the anchor fitting has a second tie rod and a second abutment body for arrangement in a second workpiece in this embodiment. The first and second tie rods can be detachably connected to one another, for example can be screwed, clamped or otherwise connected, at their longitudinal end regions remote from the respective support body. Thus, such an anchor fitting can be used to connect two workpieces to one another.

A preferred concept provides that the support body is substantially ring-shaped around its largest outer circumference and/or the envelope of the plug-in axis provided for insertion into the support recess. The holder body need not be completely circular, but only circular in its envelope. It is then possible for the bearing body to be insertable into the bearing recess when the bearing recess has a circular inner contour. Thus, the support recess preferably relates to a bore, while the connecting recess expediently has a flat profile, i.e. a height which is smaller than the width.

Detailed Description

The anchor fitting shown in fig. 1 and 2 can be anchored in a workpiece W2 and serves to connect the workpiece W2 with a workpiece W1. The workpieces W1 and W2 are, for example, wood workpieces, wood panels or the like. It is obvious that the anchoring fitting is also suitable for workpieces composed of other materials, for example plastic or metal. In the interconnected state, the workpieces W1 and W2 abut one another, for example, with their workpiece end sides WS1 and WS 2.

A holding recess HA is arranged in the workpiece W1 and a connecting recess VA is arranged in the workpiece W2, which are aligned with one another in the assembled state of the anchor fitting 10 or in the assembled state of the workpieces W1 and W2, see for example fig. 3 and 4. The carrier recess WA is arranged transversely, for example orthogonally, to the two recesses VA and HA in the workpiece W2. The support recess WA extends from the workpiece flat side WF2 of the workpiece W2 into the core region of the workpiece and communicates with the connecting recess VA, which extends orthogonally or at least transversely to the support recess WA.

For anchoring the anchor fitting 10 in the workpiece W2, a support body 20 is provided, which is designed, for example, in the form of a retaining nut (haltenus) or the like. The holder body 20 has a flat profile at the end sides 21 and 24 opposite to each other, while the front and rear front sides 23 extending between the end sides 21, 24 comprise rounded portions. Between the front sides 23, longitudinal sides 22 extend, which have a substantially flattened profile, i.e. are set back relative to the circular or ring-shaped envelope of the support body 20 in a viewing angle from one of the end sides 21 or 24 toward the support body 20. However, at said longitudinal side 22a guide projection 27 is provided, which has a rounded outer circumferential contour. In the plane of the guide projection 27, the holder body 20 has a substantially circular outer peripheral contour, in addition to support ribs 23A for supporting at the inner periphery of the holder gap WA.

The support body 20, i.e. on the basis of its substantially circular outer circumferential contour, can be inserted into a likewise circular support recess WA about a plug-in axis SW, along which it can be inserted. The support body 20 is substantially ring-shaped with respect to the wrapping portion of the plugging axis SW.

Now, a construction can be considered in which the stand body 20 is supported directly and/or only at the stand accommodation WA, but this is not currently the case.

Rather, the support body 20 is at least additionally supported by means of a support body 30, which is provided and designed for engaging or for insertion into the connection recess VA. The support body 30 has, in particular, a flat profile with narrow sides 32 and flat sides 34 extending between the narrow sides 32.

The support 30 has a base 31 from which arms 40 project. The flat side 34 is, as it were, free or interrupted in the region of the arm 40, since the support body receptacle 41 for the support body 20 is located there.

The narrow side 32 of the support body 30 is rounded on the outside, i.e. it extends convexly with respect to the flat side 34. Such a circular portion can be continuous, for example, as in particular in the region of the lead-in slope 42 at the arm portion 40. However, it is also possible that the rounded portions are not continuous, so that, for example, a deepening 38 is provided at the base body 31 in the region of the narrow side 32. However, the outer circumferential contour of the narrow side 32 is also substantially circular in the region of the base body 31.

The front side 33 of the front portion or end side of the arm 40 extends as far as the support recess WA, in which the support body 20 is arranged in the assembled state of the anchor fitting 10. When the support body 20 has been arranged in the support gap WA, the support body 30 can be inserted into the connection gap VA. It is effective in the sense that the insertion movement becomes easy that the guide projection 27 of the holder body 20 is engaged into the linear guide 39 of the support body 30. The linear guide 39 is formed, for example, by a guide groove or a guide deepening at the arm 40, into which a guide projection or guide contour 27 of the support body 20 can engage.

The support ribs 37, which project in a plane approximately parallel to the flat sides 34 in front of the narrow sides 32 and can be embedded, as it were, in the material of the workpiece W2, are responsible for improved retention of the support body 30 in the connecting recess VA.

The arm 40 has the lead-in ramp 42 on its side facing away from the support body receptacle 41, i.e. the arm 40 tapers and/or tapers toward its free end region or end side 33. The outer circumferential contour of the support body 30 is smaller in the region of the arm 40 than in the region of the base body 31. As a result, the support body 30 can be inserted into the connecting recess VA more easily, since it is narrower in the region of the end side 33 than in the region of the end side 34.

The end face 35 of the support body 30 facing away from the support body 20 or the support body receptacle 41 is expediently accommodated deepened in the connecting recess VA after the workpiece end face WS2 has been aligned with the workpiece W2 or retracted into the workpiece end face WS 2.

When the support body 20 is now arranged in the support recess WA and the support body 30 is arranged in the connection recess VA, the tension rod 50 can be inserted through the through-opening 36 of the support body 30 along the plug-in axis S as far as the plug-in receptacle 26 of the support body 20 and can be clamped in the plug-in receptacle 26 by means of the clamping body 60.

The clamping body 60 is received in the clamping body receiving part 25 of the holder body 20. A rotation driving contour 62, for example for a socket wrench, is provided on the end face 61 of the clamping body 60. The clamping body 60 can be rotationally actuated by means of the rotational driving contour 62, so that it can be screwed into the clamping body receptacle 25 or can be unscrewed therefrom. At the outer circumference 63 of the clamping body 60 (which is basically designed as a screw or clamping screw fastening), there is a screw contour or screw thread which is in engagement with a screw contour at the inner circumference of the clamping body reception 25. At the end face of the clamping body 60 opposite the end face 61, i.e. at the end face projecting into the plug receptacle 26, a clamping inclination 64, in particular a taper, is provided, by means of which the tension rod 50 can be clamped in the plug receptacle 26.

The pull rod 50 has a pull rod body 51. The tie rod 50 extends along or has a longitudinal axis L. A plug-in section 52 is provided at one longitudinal end region of the tension rod 50 for insertion into the plug-in receptacle 26 of the holder body 20. At the other longitudinal end region, a helical section 58 is provided. A step 59 is present between the helical section 58 and the plug section 52.

A rotary driving contour 54, 55 is provided on the tie rod 50, by means of which the tie rod 50 can be rotationally actuated about a rotational axis and/or its longitudinal axis L. The rotational driving contour 54 is arranged at the outer circumference of the tie rod 50, in particular in the plug-in section 52.

The rotational driving contour 55 can be said to be an inner contour, which is arranged at a longitudinal end of the plug section 52.

Between the longitudinal ends 56, 57 of the tie rod 50 (however at the plug-in section 52) an inclined surface arrangement 53 for the clamping body 60 is provided. The inclined surface assembly 53 comprises adjustment inclined portions 53A, 53B which extend one after the other in the form of a cavity or V-shaped configuration. A deepening portion or the deepest point may be provided between the adjustment inclined portions 53.

I.e. when the gripping body 60 is screwed along the gripping axis K so that it comes into engagement with the pull rod 50 and occupies a gripping position, the gripping inclination 64 slides along one of the adjustment inclinations 53 so that the pull rod 50 is adjusted axially along its longitudinal axis L or the plugging axis S, i.e. towards the holder body 20. This tensioning movement serves to tension the workpiece W2 with the workpiece W1, as will also become clearer subsequently:

the pull rod 50 can be connected to the holding body 70 in a detachable manner. The holding body 70 is provided for insertion into the holding receptacle HA of the workpiece W1. The holding body 70 has a base body 71 from which holding arm portions 73 project in a fork-like manner. Between the gripper arms 73, an actuating recess 79 is provided, into which a wedge 80 engages. The tie rod 50 can be connected to the wedge 80, i.e. can be screwed thereto. The spiral section 58 can be screwed into a spiral receptacle 83 on the end face 81 of the wedge 80, for example. Laterally next to the screw receptacle 83, an actuating ramp 82 is provided, which can slide along the inclined surface 78 or the inner side of the actuating recess 79, so that it opens the clamping arms 73 outward, as a result of which they come into clamping contact with the narrow side or the narrow inner side of the holding recess HA.

Ribs 77, in particular elastic ribs, are advantageously also provided at the clamping arms, which improve this form-fitting clamping abutment of the clamping arms 73.

The holding body 70 has a flat profile in principle, so that it, like the supporting body 30, has narrow sides 72 opposite one another, which are present in particular at the outer sides of the clamping arms 73. The flat sides 74 extend between the narrow sides 72, in particular in the region of the base body 71. Furthermore, the holding body 30 has a passage opening 76 which extends from an end face 75 facing the tie rod 50 or the supporting body 30 (which is currently designed as a flat side) to an actuating recess 79 between the clamping arms 73. The screw section 58 can be inserted through the through-opening 76 and can be screwed into the wedge 80. Thereby, the clamp arm portions 73 are opened.

In this connection, the function of the rotational entrainment profiles 54 and/or 55 is also clear. The operator can actuate the rotation driving profiles 54, 55, i.e. by means of an assembly tool, such as a socket wrench, an open-end wrench, a ring wrench or the like, in order to screw the pull rod 50, as it were, into the wedge 80 and thereby clamp the holding body 70 in the holding recess HA.

It is apparent that the longitudinal axis L of the tie rod 50 may thus be undesirably aligned with the center axis of the plug receptacle 26 (with respect to the plug axis S) of the holder body 20. However, this is without problems if the plug receptacle 26 has both a transverse width which allows the insertion of the plug section 52 of the tension rod 50 and a transverse correction.

The plug receptacle 26 has an orientation transverse width Q which is greater than the movement play which is necessary for the insertion of the plug section 52 into the plug receptacle 26 itself. This can be seen in particular in the illustration according to fig. 5. Within the plug receptacle 26, the plug projection 52 of the tie rod 50 can be positioned not only in the middle position PM, but also in lateral positions P1 or P2 offset from the middle position PM and advantageously in a plurality of positions in between.

The plug section 52 is ideally supported in the plug receptacle 26 opposite the clamping body 60. The plug section 52 is supported on the bottom face 28 of the plug receptacle 26 with a flat support face 52A (which is provided, for example, by one of the hexagonal outer sides of the polygonal rotation driving contour 54). The bottom surface 28 is opposite the clamping body 60 and thus ideally supports the tension rod 50 relative to the clamping body 60. Furthermore, it is apparent that the pivot profile 54 in principle prevents a lateral adjustment or alignment of the tie rod 50 within the directional transverse width Q, since the outer edge of the pivot profile 54 can project laterally in front of the bearing surface 52A (see fig. 5). In order to remedy this problem, the plug receptacle 26 widens outwardly away from the bottom face 28, so that the orientation transverse width Q is also obtained in the region of the projection 52B which is present from the bearing face 52A, i.e. in the region of the edge of the rotational driving contour 54.

Furthermore, the plug receptacle 26 has a transverse height H transverse to the orientation transverse width Q. The lateral height H is less than the orientation lateral width Q. Thus, the plug receptacle 26 has a flat profile. The transverse height H is the clear span of the plug receptacle 26 between the bottom face 28 and at least one support face 28A opposite the bottom face 28. The at least one support surface 28A is suitably a flat surface. The at least one support surface 28A expediently runs parallel to the bottom surface 28. Basically, there are two support faces 28A between which the clamping body 60 is arranged.

For a visually satisfactory covering of the anchoring fitting 10, in particular of the support body 20, a covering 90 is provided. The cover portion 90 includes, for example, a plate 91 that is substantially aligned with the workpiece flat side WF2 when the cover portion 90 is seated at the anchor fitting 10. The plate body 91 has a retaining projection 92 which can be brought into engagement with the support body 20, for example in the region of the receptacle 22A. The receptacle 22A is, for example, a recess or another deepened portion, which is arranged on the longitudinal side 22 or in the region between the longitudinal side 22 and the end side 21. Obviously, other anchoring solutions, such as variants not shown in the figures, with retaining projections, for example of the plug-in type, which can engage into the rotation driving contour 62 of the clamping body 60, can also be considered.

A variant of the anchoring fitting 10 is possible without problems and is shown, for example, in fig. 6. The tie rod 50 shown here has, for example, a thread 158, which is self-cutting and by means of which it can be screwed directly into a workpiece, for example, a wood workpiece.

The connection fitting 110 according to fig. 7 and 8 can be assembled in different ways. Identical or identical types of components are provided with the same reference numerals and are not explained in more detail. The anchor fitting 110 has, for example, a support body 20A, 20B corresponding to the support body 20, which support body 20A, 20B can be arranged in a support recess, not designated in greater detail, of the workpieces W4 and W5. Furthermore, the workpieces W4 and W5 have connecting recesses into which the supporting bodies 30 can be inserted respectively, which supporting bodies can be brought into engagement with the respective support body 20A, 20B.

The tie rods 50A, 50B, which are similar in principle to the tie rods 50, can be brought into a clamping connection with the holder bodies 20A, 20B. However, screw means are provided in the region of the longitudinal ends 57 at the tie rods 50A, 50B for screwing the tie rods 50A, 50B to one another. The screw means comprise, for example, the already mentioned screw section 58, which is suitable for screwing into the screw receptacle 158 of the further tension rod 50B. This screwing can be effected directly, as shown in fig. 8.

However, it is also possible to arrange a further workpiece W3, for example a side wall of a piece of furniture, in a sandwich-like manner between the workpieces W4 and W5. In this case, the workpieces W4 and W5 are, for example, the shelf bottom, the upper bottom or the lower bottom of a cabinet.

A holding recess of the type of the holding recess HA is provided in the workpiece W3, into which the holding body 170 can be inserted. The holder 170 has one sub-holder 171 and another sub-holder 172, which can be inserted into each other. The sub-holders 171, 172 are inserted into the holding space of the work W3 from the sides opposite to each other. In this case, the holding projection 175 of the sub-holder 171 can be inserted into the plug receptacle 176 of the other sub-holder 172.

At the end face assigned to the outside of the workpiece W3, the sub-holding bodies 171, 172 have, for example, projections 174 in order to limit the insertion movement into the holding receptacles of the workpiece W3.

The tie rods 50A, 50B can be preassembled at the sub-holders 171, 172. For example, in the region of the step 59 of the respective tie rod 50A, 50B, a latching contour 153, for example a latching projection, a latching receptacle or the like, is provided, which can be brought into latching engagement with a mating latching contour 173 at the sub-holders 171, 172.

The retaining body 170 has a through-opening 176, through which the tie rods 50A, 50B, i.e. in particular the spiral sections 158, 58 thereof, can be plugged. A sub-region of the through opening 176 is provided at each of the sub-holders 171, 172.
