Description

[0017] Further expedient design embodiments and advantages of the invention are the subject matter of the following description of exemplary embodiments of the invention with reference to the figures of the drawing, wherein the same reference signs refer to functionally equivalent components, and wherein

[0018] FIG. 1 shows an exemplary embodiment of the fastening clamp according to the invention in a frontal view;

[0019] FIG. 2 shows a perspective view of the fastening clamp as per FIG. 1, said fastening clamp being assembled on an L-profile;

[0020] FIG. 3 shows a cross-sectional view of the fastening clamp according to FIG. 2; and

[0021] FIG. 4 shows the fastening clamp according to FIG. 3 from below.

[0022] FIG. 1 shows an exemplary embodiment of the fastening clamp 1 according to the invention in a frontal or front view. The fastening clamp has two clamping brackets 2 and 3 which in a clamping direction are mutually opposite, wherein two clamping screws 4 and 5 are provided as bracket contact pressure means in the clamping bracket 2. The clamping bracket 2 in the two lateral external regions thereof has two through openings which are provided with an internal thread (not illustrated). The clamping screws 4 and 5 have an external thread (likewise not illustrated in the figures) by way of which said clamping screws 4 and 5 engage in the internal thread of said through openings. The clamping brackets 2 and 3 delimit a clamping gap 6 which is provided for receiving a leg of a profiled support.

[0023] The clamping brackets 2 and 3 are rigidly interconnected by connection webs 7 and 8, said connection webs 7 and 8 in turn being rigidly interconnected by an upper transverse web 9 and a counter bearing 10.

[0024] FIG. 2 shows the fastening clamp 1 in a perspective view, wherein said fastening clamp 1 is fixedly clamped to an L-profile 11. The L-profile 11 has a free leg 12 by way of which the L-profile 11 extends into the clamping gap 6. A clamping force is generated by rotating the clamping screws 4 and 5. Moreover, a Z-profile 13 can be seen as a transverse clamping unit, wherein the Z-profile 13 has a clamping tongue 14 as the first free leg and a second free leg 15, the free ends of said legs facing away from one another. Clamping tongue contact pressure means 16 which are specified for generating a transverse clamping force are provided on the second free leg 15. The clamping tongue contact pressure means 16 in the exemplary embodiment shown are configured as a transverse clamping screw 16. The transverse clamping screw 16 has an external thread which is not illustrated in the figures. The external thread engages in the internal thread of a through opening which is provided in the second free leg 15. The fastening clamp 1 in the exemplary embodiment shown in FIG. 2 is shown in a position in which the transverse clamping screw 16 is in contact with the counter bearing 10. The second free leg 15 and the clamping tongue 14 are interconnected by way of a central portion, reference to the latter to be made in yet more detail below.

[0025] FIG. 3 shows the fastening clamp according to FIG. 2 in a cross-sectional lateral view. The construction of the Z-profile 13 can be particularly readily seen in this illustration. It is highlighted in particular that the Z-profile 13, besides the clamping tongue 14, has the second free leg 15, the former and the latter extending in different directions. A central portion 17 which connects the second free leg 15 to the clamping tongue 14 can moreover be seen. An elongate bore 18 is configured within the central portion 17. A holding shank 19 of a fastening screw 20 which engages in a clearance that is provided with an internal thread in the clamping bracket 4 extends through the elongate bore 18. A washer 22 can be seen between a fastening screw head 21 and the central portion 17 of the Z-profile 13. The elongate bore 18, the fastening screw 20, and the washer 22 provide the transverse guiding means which enable a movement of the Z-profile 13 in a transverse direction, said Z-profile 13 by rotating the transverse clamping screw 16 contacting the locationally fixed counter bearing 10, wherein the longitudinally guided clamping tongue 14 in FIG. 3 is moved to the left. If an L-profile is located in the clamping gap 6, the clamping tongue 14 engages the L-profile from behind, wherein finally a transverse clamping force is provided which extends orthogonally to the clamping force by way of which the free leg of the L-profile that is disposed in the clamping gap 6 is impinged.

[0026] It can moreover be seen that the connection webs 7 and 8 have in each case one clamping bracket portion 23 and 24, each fixedly connected to a clamping bracket 2 or 3, respectively. The clamping bracket portions 23 and 24 are interconnected by way of an arcuate central portion 25. In each case one fastening flange 26 and 27 is configured on the clamping bracket portions 23 and 24. Objects can be fastened to the fastening flange 26 or 27 and can thus be held by said profile.

[0027] FIG. 4 shows the counter bearing according to FIG. 3 in a view from below, in which the fastening flange 27 is particularly well highlighted. It can be seen in particular that the fastening flange 27 has assembly openings which serve for fastening an arbitrary object.
