Abstract

The anti-theft device comprises a nut (3) operable only by a special driver (8). This driver may be turned by a spanner acting on the bolt head (9), to drive the nut by means of pegs (6) fitting into corresponding holes (5). The nut, with a cylindrical body, is tightened on the thread (2) to hold the wheel or item (4) against the seating surface (1). The pegs and holes are arranged in a pattern unique to the particular driver and nut set. A cup (10) is a loose fit around the neck of the nut, and prevents the use of any form of grips or pliers to turn the nut. A metal or plastics trim may be fitted over the mouth of the cup.

Description

DISPOSITIF ANTIVOL POUR ROUE DE VEHICULE OU ANALOGUE
La présente invention concerne un dispositif antivol pour roue de véhicule ou analogue, ce dispositif comportant un écrou, tête de boulon ou analogue ne pouvant être serré ou desserré que grâce à une clé personnelle spéciale, laquelle est propre à coopérer, par des ergots en saillie sur sa face frontale, avec des trous correspondants débouchant sur la face frontale dudit écrou, tête de boulon ou analogue, ce dernier ayant de préférence une surface latérale cylindrique.ANTI-THEFT DEVICE FOR VEHICLE WHEEL OR THE LIKE
The present invention relates to an anti-theft device for a vehicle wheel or the like, this device comprising a nut, bolt head or the like which can only be tightened or loosened by means of a special personal key, which is capable of cooperating, by projecting lugs on its front face, with corresponding holes opening onto the front face of said nut, bolt head or the like, the latter preferably having a cylindrical lateral surface.

La disposition des ergots en saillie sur la face frontale de ladite clé personnelle, disposition qui correspond évidemment à celle des trous qui débouchent sur la face frontale de l'écrou ou tête de boulon, peut avoir un grand nombre de configurations différentes, ce qui empêche, dans la pratique, qu'une clé destinée à un écrou ou tête de boulon, et qui est vendue en même temps, ne puisse s'adapter à un écrou ou tête de boulon appartenant à un jeu différent. The arrangement of the projecting lugs on the front face of said personal key, arrangement which obviously corresponds to that of the holes which open on the front face of the nut or bolt head, can have a large number of different configurations, which prevents , in practice, that a wrench intended for a nut or bolt head, and which is sold at the same time, cannot be adapted to a nut or bolt head belonging to a different set.

Ainsi seul le propriétaire légitime de la clé pourra desserrer les écrous ou têtes de boulon qui lui sont destinés. I1 s'agit donc là d'un dispositif antivol très efficace, utilisable notamment pour éviter les vols des roues des véhicules. Thus, only the legitimate owner of the key can loosen the nuts or bolt heads intended for it. I1 is therefore a very effective anti-theft device, usable in particular to prevent theft of vehicle wheels.

I1 reste cependant possible qu'un voleur équipé d'une forte pince puisse enserrer entre les mâchoires de celle-ci la surface latérale de l'écrou ou tête de boulon, puis en effectuer le desserrage, nonobstant le fait que pour limiter ce risque cette surface latérale, comme indiqué plus haut, est cylindrique. I1 remains however possible that a thief equipped with a strong clamp can enclose between the jaws of the latter the lateral surface of the nut or bolt head, then loosen it, notwithstanding the fact that to limit this risk this lateral surface, as indicated above, is cylindrical.

Le but de la présente invention est d'éviter ce risque d'opération illicite, et à cet effet, un dispositif antivol du type défini au début est caractérisé en ce qu'il comporte une cuvette montée folle sur ledit écrou, tête de boulon ou analogue, emprisonnée entre celui-ci et la pièce sur laquelle il est serré, cette cuvette entourant étroitement, au moins sur une majeure partie de sa hauteur, ledit écrou, tête de boulon ou analogue, en laissant un jeu minime autour de ladite surface latérale cylindrique. The object of the present invention is to avoid this risk of illicit operation, and for this purpose, an anti-theft device of the type defined at the start is characterized in that it comprises a bowl mounted madly on said nut, bolt head or similar, trapped between it and the part on which it is clamped, this bowl closely surrounding, at least over a major part of its height, said nut, bolt head or the like, leaving minimal play around said lateral surface cylindrical.

Ainsi toute tentative du genre décrit plus haut, même avec une forte pince, est vouée à l'échec, puisqu'elle n aurait pour effet que de faire tourner - inutilement ladite cuvette folle. Thus any attempt of the kind described above, even with strong pliers, is doomed to failure, since it would only have the effect of causing the idle bowl to spin - unnecessarily.

On peut se servir du bord de la cuvette folle comme d'un support pour un bouchon enjoliveur, encastré intérieurement ou extérieurement sur ce bord de la cuvette. One can use the edge of the mad bowl as a support for a decorative cap, embedded internally or externally on this edge of the bowl.

Dans les figures du dessin ci-annexé
- la figure 1 est une vue représentant en coupe axiale un dispositif antivol conforme à l'invention, mettant en oeuvre un écrou antivol vissé sur un goujon, et en vue extérieure la clé spéciale correspondante
- la figure 2 représente ce dispositif antivol vu de face
- la figure 3 représente en coupe axiale un dispositif antivol conforme à l'invention, mettant en oeuvre la tête antivol d'un boulon vissé dans un support, cette tête étant recouverte d'un bouchon enjoliveur encastré extérieurement sur le bord de la cuvette folle ; et
- la figure 3a représente en coupe axiale une variante avec un bouchon enjoliveur encastré intérieurement sur le bord de la cuvette folle.In the figures of the attached drawing
- Figure 1 is a view showing in axial section an anti-theft device according to the invention, using an anti-theft nut screwed onto a stud, and in external view the corresponding special key
- Figure 2 shows this anti-theft device seen from the front
- Figure 3 shows in axial section an anti-theft device according to the invention, using the anti-theft head of a bolt screwed into a support, this head being covered with a hubcap plug embedded externally on the edge of the mad bowl ; and
- Figure 3a shows in axial section a variant with an embellished cap internally embedded on the edge of the mad bowl.

Sur les figures 1 et 2 on a référencé en 1 un support quelconque, muni d'un goujon fileté 2. L'écrou spécial antivol est référencé 3 et est vissé sur le goujon 2 en enserrant entre lui et le support 1 un organe quelconque, qui peut être une jante 4 de roue de véhicule. Cet écrou, comme mieux visible sur la figure 2, possède une surface latérale cylindrique 17, et est pourvu de quatre trous 5 disposés selon une configuration irrégulière de sorte à rendre possible un très grand nombre de combinaisons différentes, selon le principe des clés.  In FIGS. 1 and 2 there is referenced at 1 any support, provided with a threaded stud 2. The special anti-theft nut is referenced 3 and is screwed onto the stud 2 by enclosing between it and the support 1 any member, which can be a vehicle wheel rim 4. This nut, as best seen in Figure 2, has a cylindrical side surface 17, and is provided with four holes 5 arranged in an irregular configuration so as to make possible a large number of different combinations, according to the principle of the keys.

Cette configuration correspond exactement à la disposition de quatre ergots 6 en saillie sur la face frontale 7 d'une clé personnelle spéciale 8 pourvue d'une tête hexagonale classique 9, par exemple pour clé courante de 17 ou de 19 mm. Ainsi on conçoit que seul le propriétaire de la clé 8 pourra serrer ou desserrer l'écrou 3 en orientant la clé 8 autour de son axe pour que les ergots s'introduisent tous dans les trous 5 de l'écrou. This configuration corresponds exactly to the arrangement of four lugs 6 projecting from the front face 7 of a special personal key 8 provided with a conventional hexagonal head 9, for example for a common key of 17 or 19 mm. Thus it is understood that only the owner of the key 8 can tighten or loosen the nut 3 by orienting the key 8 around its axis so that the pins are all introduced into the holes 5 of the nut.

La cuvette folle 10 disposée autour de l'écrou empêche qu'un tiers non autorisé ne procède à son desserrage, par exemple à l'aide d'une forte pince, puisque sans la clé spéciale 8 il n'est alors possible de faire tourner que la cuvette folle 10, ce qui est évidemment sans effet sur l'écrou 3. The crazy bowl 10 arranged around the nut prevents an unauthorized third party from loosening it, for example using a strong pliers, since without the special key 8 it is then possible to rotate than the crazy bowl 10, which obviously has no effect on the nut 3.

Le même avantage est obtenu grâce à la cuvette folle 11 montée de façon semblable autour de la tête 12 spéciale d'un boulon 13, lequel est utilisé ici (voir figure 3) pour serrer une pièce 14 sur un support 15. La cuvette folle 11 peut servir de support à un bouchon enjoliveur 16 ou 16' par exemple en matière plastique, encastré extérieurement sur le bord de la cuvette 11 (figure 3), ou intérieurement sur ce bord (figure 3a).  The same advantage is obtained thanks to the mad cup 11 similarly mounted around the special head 12 of a bolt 13, which is used here (see FIG. 3) to tighten a workpiece 14 on a support 15. The mad bowl 11 can serve as a support for an embellishing cap 16 or 16 ′, for example made of plastic material, embedded externally on the edge of the bowl 11 (FIG. 3), or internally on this edge (FIG. 3a).

Un tel bouchon pourrait aussi être monté sur la cuvette folle 10 du mode de réalisation des figures 1 et 2.  Such a plug could also be mounted on the mad cup 10 of the embodiment of FIGS. 1 and 2.
