Device for fastening an accessory to a support part

1. Field of the Invention

This invention relates to a device for fastening an accessory to a support.

2. Description of the Related Art

One known device for fastening an accessory to a support is disclosed by DE 199 63 721 A1. In this device for fastening an accessory to a support, there is a plug-in member that has a plug-in shaft on which are formed means of locking in the form of spring arms placed on both sides of a central strap and in a foot area on the central strap, to fix the plug-in member on the support, and that has a head shaft that is connected to the plug-in member and has a head plate and a counterplate, between which is formed an engagement system. A head member movable laterally relative to the plug-in member is engaged with the engagement system after first latching irreversibly, to which in turn an accessory can be fastened essentially with zero clearance by a detachable snap connector. This allows the accessory to be fastened to the support with a certain tolerance.

The task underlying the invention is to describe a device for fastening an accessory to a support with which the accessory can be very strongly fastened to the support.

Because of the existence in the device pursuant to the invention of a slider movable in a guide recess of a guide strap formed on the counterplate, which has a locking system that is engaged with the engagement system in a locked position, the accessory can be locked with the device pursuant to the invention with an appropriate configuration of the accessory, so that the accessory is connected with extremely high strength to the support in the absence of destructive force effects.

Corresponding reference characters indicate corresponding parts throughout the several views. Although the exemplifications set out herein illustrate embodiments of the invention, in several forms, the embodiments disclosed below are not intended to be exhaustive or to be construed as limiting the scope of the invention to the precise forms disclosed.

FIG. 1 in perspective view shows an example of embodiment of the device pursuant to the invention made of a hard elastic synthetic material that has a plug-in part 1 and a slider 2. The plug-in part 1 equipped with a cylindrical plug-in shaft 3, on which two diametrically opposite spring tabs 4 are formed as means of locking in this example of embodiment. Each spring tab 4 is bonded to a foot area 5 of the plug-in shaft 3 and projects diagonally radially away from the foot area 5 beyond the plug-in shaft 3. The plug-in part 1 has a cover shield 6 on the end of the plug-in shaft 3 opposite the foot area 5, which extends radially over the plug-in shaft 3 and is crowned toward the foot area 5 of the plug-in shaft 3.

On the side of the cover shield 6 opposite the plug-in shaft 3, the plug-in part 1 has a head shaft 7 that carries on its end facing away from the cover shield 6 a head plate 8 as a head terminal, which borders on the end an annular groove 9 adjacent to it introduced into the head shaft 7 as an engagement system. A counterplate 10 is formed opposite the head plate 8, which extends radially outward away from the head shaft 7 beyond the cover shield 6. A guide strap 11 oriented essentially at a right angle to the counterplate 10 is formed on the end of the counterplate 10 away from the head shaft 7 extending to the side of the counterplate 10 facing the head shaft 7, in which is made a rectangular guide recess 12 whose long side is oriented at a distance from and parallel to the counterplate 10, and into which the slider 2 is inserted movably in the illustration according to FIG. 1.
