Technical Field

The invention relates to a conveying device for conveying conveyed goods in a conveying direction.

Background

Such conveying devices are used in the beverage industry for conveying discrete items and usually have a plurality of conveying elements, in particular also in the form of conveyor chains or articulated belt chains, which each form a closed loop and are driven in a swivelling manner. Such a conveying device is sufficiently known to the person skilled in the art. The conveying elements each form a common horizontal or substantially horizontal conveying plane or conveying surface with the length above them, which is supported against the at least one sliding guide, on which conveying plane or conveying surface the transported goods stand with their transported goods bottom or their standing bottom.

Such a conveying device is in particular a conveying carrier in the beverage industry, which has the effect of conveying, for example, more than 10000, preferably more than 50000, discrete items, for example containers, per hour.

Such a conveying device therefore usually comprises a support or machine frame on which the conveying elements are received, held and/or guided. In this case, the individual supports are usually matched in their respective length and/or width to a defined range of dimensions, so that the individual supports can be combined and the individual machines of the entire production plant within the beverage industry can be connected to one another. For this purpose, the support has a support body on which profile elements, for example M-profiles, U-profiles, flat profiles, tube profiles, in particular C-profiles, are arranged. On the upper side of the profile elements, conveying elements, preferably conveying chains, extend, wherein the conveying elements are moved by a drive motor in an infinitely revolving manner and are guided in a sliding manner on the profile elements.

It is also known to provide sliding elements, in particular sliding strips, which form a lining for the conveying elements with a low coefficient of friction in order to reduce the coefficient of friction between the profile elements and the conveying elements, in order to thereby reduce the wear on the conveying elements and the driving force required for conveying the elements.

The conveying element is moved in the conveying direction by a revolving sprocket. On the conveying element, discrete articles, in particular containers, stand. Due to the dead weight of the bulk goods and the conveying elements, a large tensile force acting in the conveying direction is exerted on the sliding elements. In order to design the individual chain links so as to be permanently alternated between the return and/or return path sections during the pivoting operation of the conveying element as material-saving as possible, entry fingers are therefore provided at the transition region between the return and/or return path sections.

In the prior art, the individual feed fingers and the sliding element are connected to one another, in particular screwed or riveted, by means of a screw connection in a complicated manner, which is very time-consuming and therefore expensive.

Detailed Description

The exemplary transport device, which is designated in the figures generally by 100, serves in particular for transporting transport articles 102 in at least one transport direction a between container processing machines and/or transfer stations, not shown in detail, for the packaging industry and/or the beverage industry, respectively. The conveying device 100 here particularly advantageously has the effect of conveying more than 10000, preferably more than 50000, discrete articles 102, for example containers, per hour.

In particular, the conveyor system 100 comprises at least one conveyor element 103, which forms a closed loop and is driven in an endless manner in the conveying direction a and which can be designed, for example, as a conveyor belt, a conveyor chain, a hinged belt chain or a conveyor mat. The length of the conveying element 103 supported with its upper side against at least one sliding bar 113 (shown in fig. 2 or 4) forms a horizontal or substantially horizontal conveying plane or conveying surface TE on which the conveying goods 102 stand with their conveying goods bottom or their standing bottom. As can be seen in particular from fig. 2 and 4, at least one conveying element 103 is guided in a sliding bearing manner on at least one slide 113 at least along a conveying section TS. A plurality of, for example, two, three, four or more conveying elements 103 may also be provided, which are arranged next to one another in a multidirectional manner, i.e. transversely or perpendicularly to the conveying direction a, so that the plurality of conveying elements 103 form a common conveying plane TE, at least with a portion of the respective upper length of their respective loops, on which conveying plane TE the transported articles 102 can stand at least partially with their bottom faces.

At a front end 1.11 with respect to the conveying direction a and a rear end 1.12 with respect to the conveying direction a, the at least one conveying element 103 is guided by the deflection devices 141, 142, respectively, wherein the at least one conveying element 103 is guided, in particular at its front end 1.11, by the front deflection device 141 and at its rear end 1.12 by the rear deflection device 142. Between the front and rear deflecting devices 141, 142, a conveying section TS for transporting the articles 102 is formed by means of at least one conveying element 103. The transport section TS on which the transport articles 102 can be transported is therefore configured in particular from the rear deflecting device 142 in the transport direction a to the front deflecting device 141.

It can also be provided here that the front and/or rear steering 141, 142 is designed to be drivable in a motor manner. The front and/or rear steering devices 141, 142 can be designed, for example, as electric motors, preferably gearless electric motors, for example in the form of direct-drive electric motors, preferably in the form of stepping motors, servomotors or torque motors.

Furthermore, as is only schematically illustrated in fig. 1, the conveyor system 100 has a machine frame 110, which forms a stand and on which all components of the conveyor system 100 are arranged or received and by means of which the conveyor system 100 stands on the ground BE via support elements 101 or legs.

At least one slide 113 is arranged at least in sections along the transport section TS on at least one profile element 112, which is connected to at least one carrier 111 of the machine frame 110.

As can be seen in more detail here, in particular from fig. 4, the machine frame 110 has at least one carrier body 111 which extends over the entire conveying element width, i.e. transversely to the conveying direction a, is designed as a base carrier for receiving further components and parts of the conveying installation 100 and on which two supporting elements 101 are arranged in a fixed manner. The carrier body 111 forms a carrier element, for example a U-shaped profile carrier made of stainless steel.

Preferably, the machine frame 110 comprises two or more carrier bodies 111, which are arranged, for example, distributed at uniform intervals over the entire length of the transport section TS and are each supported on the floor BE by at least two support elements 101. In this case, advantageously, at least one carrier body 111 is arranged in the region of the front end 1.11 of the transport device 100 and at least one further carrier body 111 is arranged in the region of the rear end 1.12 of the transport device 100.

The carrier body 111 has a preformed hole 20, in particular in a planar surface section 23, which has a geometry deviating from a circle, which may be formed, for example, by a leg of the U-shaped profile carrier 111. Fig. 6b shows a partially illustrated planar surface section 23 of the carrier 111 in a schematic top view, with the preformed hole 20. The preformed hole 20 can be embodied in particular as mirror-symmetrical and has two identical circular arc sections 20.1 and two identical rectangular sections 20.2.

As can be seen in particular from fig. 4, the carrier body 111 extending transversely to the conveying direction a can also have a plurality of prefabricated holes 20, which are each arranged substantially below a respective slide bar 113.

At least one transport element 103 is guided in a sliding bearing manner on at least one slide 113 at least along a transport section TS, wherein the at least one slide 113 is arranged parallel or substantially parallel in a plane below the transport plane TE. However, a plurality of sliding bars 113 is advantageously provided, in particular particularly advantageously along the entire transport section TS along which the transport element 103 is moved. In this case, a plurality of sliding bars 113 can be arranged below the conveying element 103 both transversely to the conveying section TS and longitudinally to the conveying section TS. For example, as shown in fig. 4, four sliding bars 113 arranged transversely to the transport path TS can be provided, which are arranged substantially parallel to one another in their respective longitudinal extent, i.e. in the transport direction a.

It is also possible to arrange a plurality of sliding bars 113 both transversely and longitudinally to the transport section TS, which are arranged directly adjacent to one another, preferably over the entire length of the transport section TS. Furthermore, the sliding bars 113 arranged in the longitudinal direction of the transport section TS are advantageously arranged flush with respect to one another, in particular in such a way that a row of sliding bars 113 lying in line one behind the other is formed which engage directly next to one another. It is also provided that the adjacently arranged sliding bars 113 are flush with respect to one another or are arranged.

Preferably, the sliding bar 113 has a surface with a low coefficient of friction on its upper side facing the conveying element 103, which may in particular be composed of plastic.

In this case, at least one profile element 112 is substantially C-shaped in its cross section shown in fig. 4. In this case, the at least one profile element 112 has three leg sections, namely a middle leg section 22.1 and two side leg sections 22.2. Here, a sliding bar 113 is assigned to the middle leg section 22.1. Such profile elements 112 are known to the person skilled in the art of conveying devices 100 in the beverage industry as C-profile elements or U-profile elements. These profile elements in turn extend in parallel planes below the plane developed by the sliding bar 113 and thus also in planes below the transport plane TE. The lateral leg sections 22.2 are oriented in their respective longitudinal extension of their cross section at an angle to the cross section of the central leg section 22.1, which angle is preferably configured to be less than 90 degrees, so that the respective free ends 22.3 of the two lateral leg sections 22.2 converge in cross section at an acute angle to one another in the imaginary extension of the free end 22.3. The middle leg section and the side leg sections 22.1, 22.2 bound, in their cross-section, a recess 21 which is open downward, i.e. in the direction of the carrier body 111, and from which it is accessible. The recess 21 is thus formed as a groove which is formed in its cross section as a truncated cone, i.e. tapers with two side leg sections 22.2 on the side facing away from the sliding bar 113.

The middle leg section 22.1 here essentially has a width transverse to the conveying direction a of: this width corresponds in cross section to the width of the at least one sliding bar 113 shown in fig. 4. The sliding bar 113, which is configured substantially rectangularly in a top view, not shown, on the upper side of the middle leg section, can have a length in the conveying direction a of: which corresponds to the length of the profile element 112. The profile element 112, in particular the middle leg section 22.1 thereof, can also be of substantially rectangular design in a plan view, not shown.

Fig. 2 shows a detail of the conveying device 100 in an enlarged and more detailed view, which is delimited in fig. 1 by a dashed circle in the front region 1.11, as can be seen in particular from fig. 2, at least one conveying element 103 is guided at least in sections by at least one entry finger 3 at least in the transition region from the front deflecting device 141 to the at least one sliding bar 113. The at least one entry finger 3 is designed to form a transition of the at least one conveying element 103 between the forward return and the return of the conveying device 100 that is as material-saving as possible. In particular, the at least one entry finger 3 forms a material-saving transfer of the at least one transport element 103 from the front deflecting device 141 onto the at least one slide bar 113. For this purpose, the at least one entry finger 3 is releasably connected to the at least one sliding bar 113 and/or the at least one profile element 112. The entry finger 3 is in particular formed in one piece.

According to the invention, the releasable connection of the at least one entry finger 3 to the at least one sliding bar 113 is designed as a snap-on connection RV and/or the releasable connection of the at least one entry finger 3 to the at least one profile element 112 is designed as a plug-in connection SV and/or the at least one entry finger 3 and the at least one profile element 112 are releasably connected to the at least one base carrier 111 by means of the quick-action fastening device 2.

The entry finger 3 has a guide section 4, which forms a bearing surface on its upper side 4.3 for the purpose of transferring the transport element 103 from the front deflection device 141 to the at least one slide bar 113 in a sliding bearing manner. The guide section 4 can BE rounded and/or inclined on its free end side 4.1 facing the front end 1.11, in particular with a surface section 4.2 pointing downwards, i.e. preferably at 90 degrees downwards compared to the upper side 4.3, towards the ground BE. In particular, the transition region between the upper side 4.3 and the surface section 4.2 is rounded and/or beveled. The guide section 4 is designed on its upper side 4.3 as a substantially planar, i.e., planar surface section and is made of a material having a low coefficient of friction, for example plastic.

Furthermore, the entry finger 3 may have a support section 5, which engages directly adjacent to the guide section 4 and is configured for forming a connection between the entry finger 3 and the slider 113. For this purpose, the bearing section preferably has at least one retaining element, for example at least one latching element 5.1, by means of which a latching connection RV can be established between the entry finger 3 and the sliding bar 113. The bearing section 5 is thus designed, for example, for the lockable bearing of the sliding bar 113. The detent element 5.1 can engage in a detent opening 113.1 provided in the slide bar 113, which can be embodied as a blind hole or as an opening which penetrates the slide bar 113 completely. The latching element 5.1 can be embodied in particular as a truncated cone and has an outer circumferential surface which is adapted to the inner circumferential surface of the latching opening 113.1 in such a way that the latching element 5.1 can be introduced into the latching opening 113.1 and locked in the latched position.

Furthermore, the entry finger 3 can have a receiving section 6, which in turn engages adjacently to the support section 5, for receiving the profile elements 112 in a releasable plug-in manner. The entry finger 3, in particular the receiving section 6 thereof, forms a releasable plug connection SV with the profile element 112 in that: the outer geometry of the receiving section 6 is adapted to the inner geometry of the profile elements 112 in such a way that the receiving section 6 is received in a form-fitting manner by the inserted profile elements 112. The plug connection SV between the entry finger 3 and the profile element 112 is thus established, in particular, by a form-fit connection of the two components. The inserted profile elements can be configured, in particular, as shown in fig. 4 and 5, in a C-shape in their cross section.

In this case, the receiving section 6, the bearing section 5 and the guide section 4 can each be arranged offset from one another in a stepped manner such that stop surfaces 7,8 are formed in the respective transition regions. In more detail, a first stop face 7 for a sliding bar 113 arranged on the support section 5 is formed between the guide section 4 and the support section 5. Furthermore, a second stop surface 8 for the profile element 112 inserted in a form-fitting manner onto the receiving section 6 is formed between the receiving section 6 and the bearing section 5.

Furthermore, the entry finger 3 can have a plug section 9, which in turn engages adjacently on the receiving section 6, by means of which the entry finger 3 can be releasably connected to the quick-action fastening device 2. The releasable connection of the quick-action fastening device 2 to the entry finger 3 can be designed in a force-locking and/or form-locking manner. The plug section 9 can be received in a form-fitting manner in a receptacle 2.1 provided in the quick-action fastening device 2, i.e. in a form-fitting and/or force-fitting manner in the form of a slot. The slot 2.1 can be designed as an opening which passes completely through the clamping body 30 of the quick-action fastening device 2 and which, in its inner geometry, is adapted to the outer geometry of the plug-in section 9 in such a way that a form-fit connection is formed when the plug-in section 9 is inserted into the slot 2.1. Furthermore, the plug section 9 can also have at least one latching projection 9.1 which latches in the recess 2.1 in the inserted state of the plug section 9, so that in addition to a form-locking connection, a force-locking connection can also be produced between the insertion finger 3 and the quick-action fastening device 2. The plug section 9 particularly advantageously has a length which corresponds at least to the width B of the quick-action fastening device 9 in the region of the slot 2.1.

The quick-action fastening device 2 is preferably designed to be adjustable between a locking position VP and a release position FP, in particular designed such that the quick-action fastening device 2 fixes, but releasably connects, the profile element 112 to the base carrier 111 in the locking position VP and releases, i.e. releases, in the release position FP.

Furthermore, it is advantageously provided that the quick-action fastening device 2 has fastening sections BA1, BA2, respectively, which extend along the central longitudinal axis MA of the quick-action fastening device 2 and are opposite one another and to which the profile elements 112 and/or the base carrier 111 can be connected. In particular, a first fastening section BA1 is provided, which can be connected to the profile element 112, and a second fastening section BA2 is provided, which can be connected to the base carrier 111.

Preferably, the first and/or second fixing section BA1, BA2 is/are configured for forming a force-locking and/or form-locking connection in the locking position VP of the quick-action fixing device 2.

In this case, it can also be provided that the first and/or second fastening section BA1, BA2 is inserted into the profile element 112 and/or the base carrier 111 in the locking position VP. The first and/or second fastening section BA1, BA2 can be inserted in particular in the locking position VP into the preformed hole 20 of the base carrier 111 and/or into the recess 21 of the profile element 112.

Therefore, it can also be provided that the first and/or second fastening section BA1, BA2 snaps into the profile element 112 and/or the base carrier 111 in the locking position VP. In particular, the first and/or second fastening section BA1, BA2 can have a locking element for this purpose, which in the locking position VP is snapped into the preformed hole 20 of the base carrier 111 and/or into the recess 21 of the profile element 112.

Furthermore, it can also be provided that the first and/or second fastening section BA1, BA2 is/are fixedly connected to the profile element 112 and/or the base carrier 111 in the locking position VP in such a way that: the first and/or second fastening section BA1, BA2 hooks with the locking element 25 the preformed hole 20 of the base carrier 111 and/or the recess 21 of the profile element 112.

Preferably, the quick-action fastening device 2 is configured to be rotatable about the central longitudinal axis MA between a locking position VP and a release position FP, in particular such that the quick-action fastening device 2 fixes, but releasably connects, the profile element 112 to the base carrier 111 in the locking position VP and releases, i.e. releases, in the release position FP. The quick-action fastening device 2 is particularly preferably designed as a twist-proof lock which establishes a force-locking and/or form-locking connection in the locking position VP.

In the exemplary embodiment of fig. 4, a plurality of, in particular four, quick-action fastening devices 2 are shown in more detail, which are each releasably connected by means of their first fastening section BA1 to a common base carrier 111 and by means of their second fastening section BA2 to the profile element 112. On the upper side of each profile element 112, a sliding bar 113 can be provided, which is releasably fastened to the respective profile element 112 by means of at least one latching connection RV. The conveying element 103 is in turn supported on a slide bar 113, which is guided in a sliding manner on the upper side of the slide bar 113. Further, left and right bracket plates 114 and 115 are provided on the side surfaces of the base carrier 111, respectively. The profile elements 112 and/or the sliding strips 113 and/or the carrier plates 114, 115 preferably extend over the entire length of the transport section TS and can be designed here in one piece or preferably in several pieces each.

Fig. 5 shows a schematic side view of an exemplary embodiment variant of the quick-action fastening device 2 according to the invention in a locking position VP, in which the profile element 112 is releasably connected to the base carrier 111 by means of the fastening device 2. In the side view shown in fig. 4, the quick-action fastening device 2 extends through a central plane ME of the central longitudinal axis MA, which is perpendicular to the plane of the drawing, i.e. the side view shown is oriented.

In particular, the first fastening section BA1 is in this case releasably brought into operative engagement with the base carrier 111, while the second fastening section BA2 is in releasable operative engagement with the profile elements 112, so that the base carrier 111 can be connected to one another via the first fastening section BA1 and the profile elements 112 can be connected to one another via the second fastening section BA 2.

Furthermore, the first fastening section BA1 has a first locking section VA1 on the free end side and/or the second fastening section BA2 has a second locking section VA2, by means of which the base carrier 111 can be held fixedly in the locking position VP by the quick-action fastening device 2 and released, i.e. released, from the quick-action fastening device 2 in the corresponding release position FP.

According to the embodiment variant of fig. 5, the carrier body 111 has, for at least releasable clamping fixation in the at least partially flat section 23, a preformed hole or opening 20 deviating from a circular shape, the cross section of which matches the longitudinal section of the first locking section VA1, in particular in such a way that the first locking section VA1 can be guided through the preformed hole 20 and the quick-action fastening device 2 can be clamped by the first fixing section BA1 on the carrier body 111 by twisting about the central longitudinal axis MA.

In addition to the first locking section VA1 on the free end, the first fastening section BA1 can also have a first abutment section a L1 that engages on the second fastening section BA2 along the central longitudinal axis MA in the direction of the latter, which preferably forms the receiving groove 24 extending perpendicularly to the central longitudinal axis MA, the first abutment section a L1 can in particular be arranged directly adjacent to the second fastening section BA2, in particular on the latter.

The receiving groove 24 is arranged here at least partially around the central longitudinal axis MA, preferably completely around the central longitudinal axis MA, and in the locking position VP forms an abutment face AF for the profile element 112 on a face section facing the carrier body 111. In particular, the receiving groove 24 is matched in terms of its dimensions to the preformed hole 20 in such a way that the receiving groove 24 cannot penetrate the preformed hole 20 or be guided through the preformed hole 20 in the locking position VP, but rather bears at least partially circumferentially around the preformed hole 20 on the flat section 23 on the side facing the second fastening section BA2, in particular in a contact-locking manner, against the flat section 23.

Furthermore, the first fastening section BA1 has at least one locking element 25 in the first locking section VA1, which is arranged on a section 27 coaxially surrounding the central longitudinal axis MA and extends radially outward from the central longitudinal axis MA and can be designed as a locking finger. Advantageously, a plurality of, in particular two, locking elements 25 are provided here, which are preferably arranged on opposite sides of the section 27 and each extend radially outward from the central longitudinal axis MA and are preferably each designed as a locking finger. The longitudinal extension of the section 27 can be adapted to the thickness of the carrier body 111 to be locked.

As can be seen in particular from fig. 6a, the at least one locking element 25 has an abutment surface 25.1 on its upper side facing the second fastening section BA2, which is inclined, in particular oriented at an acute angle, with respect to the central longitudinal axis MA.

In the locking position VP, the at least one locking element 24 is guided through the preformed hole 20 and is rotated, preferably by 40 °, relative to the carrier 111 from the release position FP into the locking position VP in such a way that the at least one locking element 25 hooks the preformed hole 20 and bears, in particular contacts-lockingly, against the flat section 23 at least partially circumferentially around the preformed hole 20 on the side of the front section 23 facing away from the second fastening section BA 2.

In more detail, the inclined contact surface 25.1 of the at least one locking element 25 is pressed by twisting the first locking section VA1 against the flat section 23 of the base carrier 111 on the side facing away from the second fastening section BA2 in a clamping and contact-locking manner in such a way that the base carrier 111 is pressed in the flat section 23 against the contact surface AF of the receiving groove 24 on the side facing the second fastening section BA2, and the flat section 23 is held in a clamping manner between the contact surface AF and the inclined contact surface 25.1.

As can be seen in particular from the planar surface section 23 of the base carrier 111, which is partially shown in fig. 6b in a schematic top view, the preformed holes 20 arranged in this surface section have a geometry deviating from a circular shape in a cross section in the top view. The pre-perforation 20 can be designed in particular as a mirror-symmetrical manner and has two identical circular-arc-shaped sections 20.1 and two identical rectangular sections 20.2, which are geometrically matched to the longitudinal cross section of the first locking section VA1 in such a way that the first locking section VA1, in particular the at least one locking element 25, can pass through the rectangular sections 20.2 and be prevented by the circular-arc-shaped sections 20.1 from being pulled out of the preformed hole 20 in the locking position VP by a rotation through 90 °. The preformed hole 20 in the planar surface section 23 can be produced here, for example, by laser, punching or drilling.

The planar surface section 23 of the base carrier 111 has an upper side 23.1 which is planar, i.e., is planar and faces the second fastening section BA2, and an underside 23.2 which is planar and faces away from the second fastening section BA 2. In particular, the upper side 23.1 and the lower side 23.2 in the planar section 23 open out planes which run parallel or substantially parallel to one another. In other words, the planar surface section 23 has a constant or approximately constant surface strength, in particular a surface thickness.

In this case, according to the embodiment variant of fig. 5, the profile element 112 has at least one profile section 22 forming a recess 21, the cross section of which matches the cross section of the second locking section VA2, in particular in such a way that, by twisting about the central longitudinal axis MA, the second locking section VA2 can be received in the recess 21 at least in sections in a form-fitting and/or force-fitting manner in order to releasably clamp the second fastening section BA2 to the profile element 112.

The quick-action fastening device 2 has in its second latching section VA2 a clamping body 30 which is essentially oval in its plan view, i.e. perpendicular to the center plane ME, and in this case tapers in the direction of the first fastening section BA1, i.e. has a comparatively smaller oval diameter, so that the clamping body 30 has a maximum length L in its side cross section facing the free end section 30.1 of the second component BT2 in its latching position VP, in particular, the clamping body 30 which is essentially oval in plan view has, in the region of the free end section 30.1, on at least two preferably opposite sides, straight contact surfaces 30.2, 30.3, by means of which the clamping body 30 in its latching position VP opens out in a clamping manner against the respective inner sides of the two side leg sections 22.2 and thus forms a side-clamping fit, the two side leg sections 22.2 can be elastically variably configured in such a way that they are deflected, i.e. bent away from the center plane ME, when the contact surfaces 30.2, 30.3 of the clamping body 30 deflect elastically from the latching position VP to the outer latching position ME.

Between the release position FP and the locking position VP, the second locking section VA2 of the quick-action fastening device 2 is preferably twisted by 40 degrees relative to the profile section 22. Fig. 5 shows the locking position VP, while fig. 6 shows the release position FP. Furthermore, the quick-action fastening device 2 can advantageously be designed in one piece, in particular in one piece, so that when the second fastening section BA2 of the quick-action fastening device 2 is twisted, the first fastening section BA1 is also twisted together, i.e. for example rotated from the release position FP into the locking position VP. The first and second fastening sections BA1, BA2 are therefore connected to one another in a force-locking manner.

In this case, the clamping body 30 has a width B in a lateral cross section in the release position FP, which width is adapted to the cross section of the profile section 22 in such a way that the clamping body 30 can be introduced into the recess 21 formed by the profile section 22 in its release position FP.

Furthermore, the clamping body 30 has such a length L in the region of the opposing contact surfaces 30.2, 30.3, i.e. the distance between the contact surfaces 30.2, 30.3, that the clamping body 30 in its locking position VP is open in clamping manner against the respective inner sides of the two side leg sections 22.2 of the second component BT2 and can thus produce a clamping fit, furthermore, the clamping body 30 is designed in such a way that it is pressed against the underside of the middle leg section 22.1 by being twisted from the release position FP into the locking position VP and, when the locking position VP is reached, bears against the underside of the middle leg section 22.1, so that a defined position of the fastening device 2 relative to the profile element 112 can be produced.

In particular, the length L and the width B of the clamping body 30 can be adapted to the dimensions of the profile section 22, in particular the middle leg section and the side leg sections 22.2.

As can be seen in particular from fig. 7a or 7b, the quick-action fastening device 2 has a through-guide in the form of an opening 28 which extends through the first and second fastening sections BA1, BA2 and which, in the region of the tube section 27, can have at least in sections an internal hexagon which forms an active surface for a tool, for example an internal hexagon wrench, so that a twisting movement between the release position FP and the locking position VP can be introduced onto the fastening device 2 by means of the tool.

The foregoing examples illustrate the invention. Of course, many variations and modifications are possible without departing from the inventive concept on which the invention is based.
