DEVICE FOR FASTENING AN ACCESSORY TO A SUPPORT PART
A device for fastening an accessory to a support has a plug-in part (1) with a plug-in shaft (3) to be inserted into a recess in the support, and a head shaft (7) that has a head plate (8) and a counterplate (10) between which an engagement system (9) is developed. A guide strap (11) that has a guide recess (12) is formed on the counterplate (10), which is located on the side facing the head shaft (7). There is also a slider (2) that is mounted to be movable in the guide recess (12) toward the engagement system (9) and is made with a locking system (16) that is engaged with the engagement system (9) when the slider (2) is advanced into a locking position. This allows an accessory with a section located between the slider (2) and the counterplate (10) to be connected to the support.

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.
SUMMARY OF THE INVENTIONThe 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.
The above mentioned and other features and objects of this invention, and the manner of attaining them, will become more apparent and the invention itself will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings, wherein:
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.
DETAILED DESCRIPTIONOn 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
In the example of embodiment of
The slider 2 is also designed with a locking system in the form of fork-shaped locking arms 16 opposite one another that are formed on the guide plate 13 at the end of the guide plate 13 opposite the end plate 14, and extend in an extension of the guide plate 13. The dimensions of the locking arms 16 and the positioning of the guide recess 12 are aligned so that when the slider 2 slides toward the head shaft 7 into an advanced locking position, the locking arms 16 lie in the annular groove 9 with essentially no clearance in the radial direction, and the steep side of the locking lug 15 rests against the side of the guide strap 11 racing the head shaft 7.
While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
Claims
1-6. (canceled)
7. A device for fastening an accessory to a support, said device comprising:
- a plug-in part with a plug-in shaft having locking members formed thereon for fixing said plug-in part on the support;
- a head shaft connected to the plug-in shaft and including a head plate and a counterplate, and an engagement system formed between said head plate and said counterplate;
- a guide strap formed on said counterplate at a lateral distance from said head plate and having a guide recess, said guide recess located on a side of said guide strap facing said head shaft at a distance from said counterplate; and
- a slider mounted for sliding movement in said guide recess toward said engagement system, said slider including a locking system engaged with said engagement system when said slider is advanced into a locked position.
8. The device of claim 7, wherein a locking structure is formed on the slider, said locking structure preventing said slider from moving out of said engagement structure in said locked position.
9. The device of claim 8, wherein said engagement structure is an annular groove and said locking system has two fork-shaped locking arms disposed opposite one another, said locking arms positioned in said annular groove in said locked position.
10. The device of claim 9, wherein said slider includes a rectangular flat plate mounted in said guide recess, said flat plate having a flat face positioned parallel to said counterplate, said locking arms formed on one end of said flat plate.
11. The device of claim 10, wherein an end plate is formed on an end of said guide plate opposite said locking arms, at least a section of said end plate projecting beyond said guide plate.
12. The device of claim 11, wherein said locking structure is a locking lug projecting beyond said guide plate.
