Abstract

The invention relates to an anti-theft nut. This nut consists of a body (1) which, at one end, exhibits a screw thread (2), immobilising spikes (3) and, at the other end, a lock (6). On the body (1), the component (8) is free to rotate and immobilised in translation by the stops (9). The component (8) exhibits a shoulder (4) for mounting the cap (5). The external shape of the component (8) is that of a hexagon head. When the owner turns the key (10), the lock (6) causes three entrainment fingers (7) to come out, which penetrate into the three cavities (11) in order to clamp or unclamp the anti-theft nut. When the owner turns the key (10) in the opposite direction, the three fingers (7) return into the body (1), thus releasing the component (8) in terms of rotation. The anti-theft nut is more particularly intended for the axles of motorcycle wheels, in order to prevent the theft of the wheels.

Description

L'Invention concerne un écrou antivol:
L'Ecrou antivol selon l'invention permet uniquement a son propriétaire de le serrer ou de le desserrer à l'aide d'une clef.The invention relates to an anti-theft nut:
The anti-theft nut according to the invention only allows its owner to tighten or loosen it using a key.

L'Ecrou antivol se compose d'un corps(l) présentant à une extrémité un filetage (2), des pointes de bloquage (3), et à l'autre extrémité une serrure (6).La pièce (8) se présente avec une forme six pans à l'extérieur, trois cavités(ll) et un épaulement (4). The anti-theft nut consists of a body (l) having at one end a thread (2), locking pins (3), and at the other end a lock (6). with a hexagonal shape on the outside, three cavities (ll) and a shoulder (4).

Montée sur le corps (1), la pièce(8) est libre en rotation et bloquée en translation par une butée (g) à chaque extrémité. Mounted on the body (1), the part (8) is free to rotate and locked in translation by a stop (g) at each end.

Lorsque le propriétaire introduit et tourne la clef dans la serrure (6) , il commande la sortie de trois doigts d'entrainement(7) qui viennent s'introduire dans les trois cavités (il) de la pièce(8),réalisant ainsi un ensemble solidaire, afin de pouvoir serrer ou desserrer l'écrou antivol(FIGURE 3). When the owner introduces and turns the key in the lock (6), he controls the exit of three drive fingers (7) which are introduced into the three cavities (il) of the part (8), thus achieving a integral, in order to be able to tighten or loosen the anti-theft nut (FIGURE 3).

Lorsque le propriétaire tourne la clef (10) dans le sens inverse, il commande la rentrée des trois doigts d'entrainement (7) dans le corps (1), libérant ainsi en rotation la pièce (8), afin de ne plus pouvoir serrer ou desserrer l'écrou antivol (FIGURE2). When the owner turns the key (10) in the opposite direction, he controls the reentry of the three drive fingers (7) in the body (1), thus freeing the part (8) in rotation, so that it can no longer be tightened or loosen the anti-theft nut (FIGURE2).

Après avoir retiré la clef de la serrure, 1' épaulement (4) permet le montage du chapeau (5), afin d'éviter toute pénétration d' eau ou poussières dans la serrure. After removing the key from the lock, the shoulder (4) allows the mounting of the cap (5), in order to avoid any penetration of water or dust into the lock.

L'écrou antivol, selon l'invention, peut etre monté sur les axes de roues de motocyclettes,afin d'éviter le vol des roues, ce type écrou pouvant etre Facilement adaptable pour les roues de voitures, camions The anti-theft nut, according to the invention, can be mounted on the wheel axles of motorcycles, in order to prevent theft of the wheels, this type of nut being easily adaptable for the wheels of cars, trucks.

Claims

I) Anti-theft nut characterized in that it comprises a body (1) having at one end a thread (2) and locking pins (3), and at the other end a lock (6).

On the body (1), the part (8), of external hexagonal shape,

is free to rotate, and locked in translation by stops (9).

The action in one direction of the key (10) in the lock (6), controls the exit of three drive fingers (7) which penetrate into the three cavities (11) of the part (8).

The parts (1) and (8) being integral, the nut can be tightened or loosened; when the key (10) is turned in the opposite direction, the lock (6) controls the reentry into the body (1) of the three dogits (7), thereby freeing the part (8) in rotation.

When the key (10) is removed, the cap (5) mounts on the shoulder (4) of the part (8).
