RETAINER WHICH CAN BE FASTENED TO A STAND

Abstract

The invention relates to a retainer which can be fastened to a stand (1), having two jaws (2) which enclose the stand (1) in a clip-like manner and are guided displaceably relative to one another perpendicularly to their butt face (3) and, on the ends forming the butt faces (3), have connecting shoulders (4) which are opposite one another in pairs. In order to create advantageous design conditions, it is proposed that the connecting shoulders (4) form, on the side thereof facing away from the butt face (3), wedge faces (5) extending inclined relative to each other and each interact with a clamping shoe (8) surrounding the wedge-shaped connecting shoulders (4) in a wedge-shaped socket (9), and that the two jaws (2) each comprise, on the inside thereof, a guide ridge (6) which protrudes beyond the butt face (3) towards the other jaw (2) and engages in a guide groove (7) of the other jaw (2).

Claims

1. A retainer that is configured to be fastened to a stand, having said retainer comprising: two jaws that enclose the stand in a clip-like manner and are each guided for displacement relative to one another perpendicularly with respect to a butt face thereof and, on ends of the laws forming the butt faces, the laws have connecting shoulders opposite one another in pairs, wherein the connecting shoulders form, on sides thereof facing away from the respective butt face, wedge faces extending inclined relative to each other and each of said wedge faces interacting with a clamping shoe surrounding a wedge shape structure of the connecting shoulders in a wedge-shaped socket, and wherein the two jaws each comprise, on an inside thereof, a guide ridge that protrudes beyond the butt face towards the other of said jaws and engages in a guide groove of the other of said jaws.

2. The retainer according to claim 1, wherein the wedge-shaped socket of the clamping shoe forms an undercut guide groove in which the wedge shape structure of the connecting shoulders engage in a form-fitting manner.

3. The retainer according to claim 1, wherein the clamping shoe comprises a resilient latching tongue interacting with a latching toothing of the connecting shoulders.

4. The retainer according to claim 1, wherein the two jaws are provided with a friction lining on inner sides thereof facing the stand.

5. The retainer according to claim 1, wherein the clamping shoe is part of a structural element configured to be fixed to the stand.

6. The retainer according to claim 1, wherein the jaws have additional connecting shoulders with a wedge shape structure engaging a second clamping shoe with a wedge shaped socket.

7. The retainer according to claim 6, wherein the wedge-shaped sockets of the clamping shoes each form a respective undercut guide groove in which the wedge shape structures of the connecting shoulders engage in a form-fitting manner.

8. The retainer according to claim 6, wherein the clamping shoe comprises a resilient latching tongue interacting with a latching toothing of the connecting shoulders.

9. The retainer according to claim 6, wherein the two jaws are provided with a friction lining on inner sides thereof facing the stand.

10. The retainer according to claim 6, wherein at least one of the two clamping shoes is part of a structural element configured to be fixed to the stand.

11. The retainer according to claim 2, wherein the clamping shoe comprises a resilient latching tongue interacting with a latching toothing of the connecting shoulders.

Description

BRIEF DESCRIPTION OF THE INVENTION

[0013] In the drawing, the subject matter of the invention is shown by way of example, wherein:

[0014] FIG. 1 shows a side view of a retainer according to the invention,

[0015] FIG. 2 shows this retainer in section along line II-II of FIG. 1,

[0016] FIG. 3 shows the two jaws of the retainer pushed together in a side view without clamping shoes and

[0017] FIG. 4 shows a clamping shoe in a partially elevated view of the inside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The retainer according to the invention comprises two U-shaped jaws 2 enclosing a parallelepipedal, preferably wooden stand 1, which jaws are provided with connecting shoulders 4 at their mutually opposite ends forming butt faces 3. These connecting shoulders 4, which lie opposite one another in pairs, form wedge faces 5 on their side facing away from the butt faces 3, which wedge faces 5 extend in an inclined manner relative to one another, as can be seen in particular from FIG. 3.

[0019] For mutual guidance of the jaws 2, which are displaceable perpendicularly to the butt faces 3, each of the two jaws 2 is provided on its inner side with a guide ridge 6, which projects beyond the butt face 3 towards the other jaw 2 and engages in a guide groove 7, which is open towards the stand 1, of the respective other jaw 2.

[0020] Clamping shoes 8, which are provided with a wedge-shaped socket 9, serve to connect the two jaws 2. This socket 9 is designed in the form of an undercut guide groove which accommodates the wedge-shaped connecting shoulders 4 of the jaws 2 in a form-fitting manner, as can be seen in particular from FIG. 2.

[0021] In order that the respective clamping position of the clamping shoes 8 on the wedge-shaped connecting shoulders 4 can be secured in a simple manner, the clamping shoes 8 form a resilient latching tongue 10 which interacts with latching teeth 11 of the connecting shoulders 4.

[0022] To clamp the retainer to a stand 1, the two jaws 2 are joined together from opposite sides around the stand 1 so that the guide ridges 6 engage in the guide grooves 7. To clamp the jaws 2 to the stand 1, the clamping shoes 8 are then fitted onto the wedge-shaped connecting shoulders 4 so that their wedge faces 5 come into operative connection with the wedge-shaped socket 9 of the clamping shoes 8 and the jaws 2 are pulled towards one another until the jaw webs 12, which connect the limbs of the U-shaped jaws 2, rest against the mutually opposite sides of the stand 1 in a clamping manner under an appropriate pretension. The clamping position of the clamping shoes 8 is secured by the latching of the clamping shoes 8 relative to the connecting shoulders 4 by means of the latching tongues 10 engaging in the latching teeth 11, and can only be released when the latching tongue 12 is disengaged from the latching teeth 11.

[0023] In order to improve the frictional connection between the jaws 2 and the stand 1, at least the jaw webs 12 may be provided with a friction lining 13 on their inner side.
