Anti-theft device intended, in particular, for vehicle wheels

Abstract

The invention relates to an anti-theft device which is intended, in particular, for vehicle wheels. The inventive device comprises an assembly consisting of: an element (1), which can be mounted to the nuts and bolts of the wheels and which is fitted with coding means; and a key (3) which is equipped with complementary decoding means. The aforementioned element (1) comprises an essentially cylindrical head (10) which is bordered externally and co-axially at a certain distance by a flange (14) which, together with the head (10), defines an annular space (13) that is designed to house the annular end part (32) of the key (3) in a tight manner. Moreover, the periphery (19) of the aforementioned essentially cylindrical head (10) comprises longitudinal cavities (12) which are parallel to the axis of the head (10) and which are disposed at random angular locations in order to form the code. Said cavities are intended to co-operate with concordant cavities (34) disposed on the inner wall (33) of the annular end part (32).

Description

technical field [0001] The invention relates to an anti-theft device, in particular for vehicle tires, comprising an assembly comprising a mechanism that can be assembled on the nut bolts of said tyre, provided with its own code and A key, the shape of the key is adapted to said code, and can make this mechanism lock or loosen on the nut bolt of said tire. Background technique [0002] Now, this type of device is expensive and has been systematically installed on most luxury or large cylinder displacement vehicles with expensive wheels. Because these wheels include alloy rims and large size tires, they are often a target for theft. goal or attempt. [0003] Of course, if these anti-theft devices are not provided in series on vehicles of the relevant class, these devices can also form an optional equipment, or be installed later if necessary on old vehicles. [0004] Now, several embodiments of immobilizers of this type are known. The most common ones consist of an adapter...

AI Technical Summary

Problems solved by technology

[0014] Consequently, these devices are no longer reliable and no longer meet the safety standards required by users

[0015] In particular, some of these devices have particularly complex structures, which are complicated to manufacture and therefore expensive, and cannot be used systematically in vehicles of the middle class

[0016] Consequently, the result of these disadvantages is to inhibit consumer interest and commercial exploitation of these immobilizers
