Description

La présente invention a pour objet une clé pour la transmission d'un couple de serrage ou de desserrage à un dispositif de vis antivol, en particulier de roues de véhicules, du type où l'accouplement est réalisé au travers d'empreintes concordantes dont les caractéristiques de forme, de dimensions et de disposition sont aptes à constituer un code.The present invention relates to a key for the transmission of a tightening or loosening torque to an anti-theft screw device, in particular of vehicle wheels, of the type where the coupling is made through concordant impressions whose characteristics of shape, dimensions and layout are suitable for constituting a code.

De manière classique, la roue d'un véhicule automobile est fixée au moyen de vis dont la tête, qui permet la transmission du couple de serrage ou de desserrage, est de forme hexagonale.Conventionally, the wheel of a motor vehicle is fixed by means of screws whose head, which allows the transmission of the tightening or loosening torque, is of hexagonal shape.

Afin d'éviter qu'un tiers puisse enlever frauduleusement les roues, il est actuellement proposé que, pour chacune des roues, au moins l'une des vis présente une tête qui nécessite une clef particulière pour pouvoir être manoeuvrée.In order to prevent a third party from fraudulently removing the wheels, it is currently proposed that, for each of the wheels, at least one of the screws has a head that requires a particular key to be able to be maneuvered.

On connaît de nombreux dispositifs de vis ou analogue munis de moyens de codage, comme par exemple ceux décrits dans les documents GB 2.006.371 , FR 2.359.730 et FR 2.567.215 . Ces dispositifs comprennent d'une part une vis dont la tête présente soit des encoches périphériques et/ou faciales arrangées angulairement de manière irrégulière, et d'autre part une clef de type douille, munie de pions ou doigts disposés selon le même arrangement et destinés à coopérer avec lesdites encoches en vue de réaliser l'accouplement susceptible de permettre le transfert de couple.Many screw devices or the like are known, provided with coding means, for example those described in the documents GB 2.006.371 , FR 2,359,730 and FR 2,567,215 . These devices comprise on the one hand a screw whose head has either peripheral and / or facial notches arranged angularly irregularly, and on the other hand a socket-type key provided with pins or fingers arranged according to the same arrangement and intended to to cooperate with said notches in order to achieve the coupling capable of allowing the transfer of torque.

Il est toutefois possible à une personne malintentionnée voulant forcer une vis telle que précédemment décrite, de se procurer une clé d'origine identique à celle de ladite vis et présentant, de manière évidente, un code différent, et sachant qu'aléatoirement certains pions ou doigts peuvent être aux bons emplacements, de réussir par forçage à déformer ladite clé et de réaliser le dévissage de ladite vis.It is however possible for a malicious person wanting to force a screw as described above, to obtain a key of origin identical to that of said screw and obviously having a different code, and knowing that randomly some pieces or fingers can be at the good locations, to succeed by forcing to deform said key and to achieve the unscrewing of said screw.

Il est en effet possible de trouver une clé présentant deux pions ou doigts disposés selon un angle identique à celui que font entre elles deux encoches d'une vis à forcer, tandis que les autres pions ou doigts qui tombent en regard de la matière, matent celle-ci et contribuent à la transmission du couple.It is indeed possible to find a key having two pins or fingers arranged at an angle identical to that between them two notches of a screw to force, while the other pins or fingers falling opposite the material, matent this one and contribute to the transmission of the couple.

La présente invention a pour but de proposer une clé pour la transmission d'un couple de serrage ou de desserrage à un dispositif de vis antivol, en particulier de roues de véhicules, qu'il n'est pas possible d'utiliser de façon frauduleuse selon la manière décrite précédemment.The object of the present invention is to propose a key for the transmission of a tightening or loosening torque to an anti-theft screw device, in particular of vehicle wheels, which can not be used fraudulently. according to the manner previously described.

La clé pour la transmission d'un couple de serrage ou de desserrage à un dispositif de vis antivol en particulier de roues de véhicules selon l'invention, où ledit dispositif de vis comporte une tête qui présente des encoches périphériques et/ou faciales arrangées angulairement de manière irrégulière, tandis que la clé est de type douille munie intérieurement de pions ou doigts disposés selon le même arrangement et destinés à coopérer avec lesdites encoches périphériques et/ou faciales en vue de réaliser l'accouplement susceptible de permettre la transmission d'un couple, lesdits pions ou doigts étant montés mobiles en déplacement axial en sorte qu'ils puissent chacun lors d'une poussée frontale se rétracter dans un logement afin de prendre une position empêchant toute coopération avec les encoches de ladite tête si celles-ci sont disposées selon un autre arrangement, ladite clé se caractérise essentiellement en ce qu'elle comporte des moyens de liaison aptes à rendre tous les pions ou doigts solidaires en déplacement.The key for the transmission of a tightening or loosening torque to an anti-theft screw device, in particular of vehicle wheels according to the invention, wherein said screw device comprises a head which has angularly arranged peripheral and / or facial notches. irregularly, while the key is of the socket type internally provided with pins or fingers arranged in the same arrangement and intended to cooperate with said peripheral and / or facial notches in order to perform the coupling capable of allowing the transmission of a torque, said pins or fingers being movably mounted in axial displacement so that they can each during a front thrust retract into a housing to take a position preventing any cooperation with the notches of said head if they are arranged according to another arrangement, said key is essentially characterized in that it comprises connecting means able to make all the pawns or fingers solidarity moving.

La clé selon l'invention présente ainsi une empreinte bien définie correspondant à un code, empreinte délimitée par des pions montés rétractiles axialement, en sorte que si la vis ne présente pas l'empreinte correspondante, l'engagement de ladite clé sur cette dernière provoque la rétraction desdits doigts ou pions, et ne permet donc pas l'engrènement et donc la transmission d'un couple.The key according to the invention thus has a well defined footprint corresponding to a code, footprint delimited by pins mounted axially retractable, so that if the screw does not does not present the corresponding imprint, the engagement of said key on the latter causes the retraction of said fingers or pins, and therefore does not allow the meshing and therefore the transmission of a couple.

On notera qu' il est connu par les documents US 5 193 420 et WO 97/14539 , des clés pour la transmission d'un couple à une vis ou analogue, comprenant une multiplicité de pions, doigts ou aiguilles parallèles, rétractables longitudinalement et de manière indépendante, en sorte que par cette rétractabilité ladite clé puisse adopter un profil complémentaire de celui de ladite vis ou analogue en vue de permettre la transmission d'un couple. Une telle clé ne peut en aucun être utilisée comme clé pour vus antivol, elle présente en effet un objet inverse de celui de la présente invention où la rétractibilité des pions ou doigts a pour but d'empêcher une telle adaptabilité. Le document US 5193420 divulgue une clé selon la préambule de la revendication 1.It will be noted that it is known from the documents US 5,193,420 and WO 97/14539 keys for transmitting a torque to a screw or the like, comprising a multiplicity of pins, fingers or parallel needles, retractable longitudinally and independently, so that by this retractability said key can adopt a profile complementary to that of said screw or the like to allow the transmission of a torque. Such a key can not be used as a key for anti-theft, it indeed has an object opposite to that of the present invention where the retractability of the pins or fingers is intended to prevent such adaptability. The document US 5193420 discloses a key according to the preamble of claim 1.

La clé selon l'invention ne peut pas être forcée sur une vis, puisque la simple tentative d'approche de la clé d'une vis non adaptée provoque la rentrée du ou des pions ou doigts qui ne sont pas exactement en face des encoches. Cependant, on peut encore détourner l'utilisation d'une telle clé. En effet, si un seul pion ou doigt ne peut pas permettre de transmettre le couple nécessaire, puisqu'il n'y pas de centrage possible, il peut arriver que deux pions ou doigts soient disposés angulairement de manière à permettre une telle transmission.The key according to the invention can not be forced on a screw, since the simple attempt to approach the key of an unsuitable screw causes the return of the pawn or fingers that are not exactly in front of the notches. However, one can still hijack the use of such a key. Indeed, if a single pin or finger can not allow to transmit the necessary torque, since there is no centering possible, it may happen that two pins or fingers are angularly arranged to allow such transmission.

D'autre part, du fait des moyens de liaison qui rendent tous les pions ou doigts solidaires en déplacement, dès qu'un seul pion ou doigt ne s'engage pas dans un encoche, tous les pions ou doigts remontent en même temps dans la clé et il n'est plus possible de transmettre le moindre couple.On the other hand, because of the connecting means that make all the pins or fingers integral moving, as soon as a single piece or finger does not engage in a notch, all the pieces or fingers go back up at the same time in the key and it is no longer possible to transmit any torque.

Selon une forme de réalisation particulière de la clé selon l'invention, elle se présente sous la forme d'une douille comportant une cavité délimitée par une paroi dans la face interne de laquelle sont pratiqués des logements longitudinaux dimensionnés et formés chacun pour recevoir un doigt ou pion apte à s'y déplacer axialement, et apte à coopérer avec des encoches périphériques que comporte la tête de vis.According to a particular embodiment of the key according to the invention, it is in the form of a socket having a cavity defined by a wall in the inner face of which are formed longitudinally sized housing and each formed to receive a finger or pin capable of moving axially, and adapted to cooperate with peripheral notches that includes the screw head.

Selon une caractéristique additionnelle de la forme de réalisation particulière de la clé selon l'invention, elle incorpore dans la cavité un insert qui y est mobile en déplacement axial, et auquel les pions sont accrochés.According to an additional feature of the particular embodiment of the key according to the invention, it incorporates in the cavity an insert which is movable in axial displacement, and which the pins are hung.

Selon une autre caractéristique additionnelle de la forme de réalisation particulière de la clé selon l'invention, l'insert présente une forme générale tubulaire et comporte un rebord périphérique tandis que les doigts ou pions présentent chacun latéralement un cran ou analogue apte à coopérer avec ledit rebord en sorte d'y assurer un accrochage.According to another additional feature of the particular embodiment of the key according to the invention, the insert has a generally tubular shape and comprises a peripheral rim while the fingers or pins each laterally have a notch or the like adapted to cooperate with said edge so as to ensure a snap.

Selon une autre caractéristique additionnelle de la forme de réalisation particulière de la clé selon l'invention, les pions ou doigts sont de forme cylindrique, le cran d'accrochage consistant en une gorge périphérique.According to another additional feature of the particular embodiment of the key according to the invention, the pins or fingers are cylindrical in shape, the catch consisting of a peripheral groove.

Selon une autre caractéristique additionnelle avantageuse de la clé selon l'invention, les pions ou doigts et les logements dans lesquels ils sont montés mobiles, sont dimensionnés en sorte que lesdits pions ou doigts coopèrent étroitement avec lesdits logements, afin de générer suffisamment de frottement pour empêcher que la réversibilité de la rétraction puisse être réalisée par gravité.According to another advantageous additional feature of the key according to the invention, the pins or fingers and the housings in which they are mounted mobile, are dimensioned so that said pins or fingers cooperate closely with said housings, in order to generate sufficient friction for prevent the reversibility of the retraction can be achieved by gravity.

Quelle que soit la forme de réalisation de la clé selon l'invention, cette caractéristique rend encore plus difficile un usage malveillant de cette clé.Whatever the embodiment of the key according to the invention, this feature makes it even more difficult for malicious use of this key.

On notera toutefois qu'il peut être prévu une possibilité de retour des pions ou doigts par gravité ou bien aidé au travers de moyens ressorts.It should be noted, however, that a possibility of return of the pawns or fingers by gravity or assisted through spring means can be provided.

Les avantages et les caractéristiques de la clé selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the key according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

En référence à la figure 1 on peut voir un dispositif de vis antivol 1 destiné à être manoeuvré au moyen d'une clé selon l'invention.With reference to the figure 1 we can see an anti-theft screw device 1 to be operated by means of a key according to the invention.

Ce dispositif de vis antivol 1 comprend un corps fileté 10 surmonté d'une tête 11, laquelle comporte un fût cylindrique 12 muni d'encoches périphériques 13 arrangées angulairement de manière irrégulière, et destinées à permettre la transmission d'un couple de serrage ou de desserrage.This antitheft screw device 1 comprises a threaded body 10 surmounted by a head 11, which comprises a cylindrical drum 12 provided with peripheral notches 13 arranged angularly of irregularly, and intended to allow the transmission of a tightening torque or loosening.

En référence maintenant aux figures 2 et 3, on peut voir une clé 2 selon l'invention, qui en l'occurrence se présente sous la forme d'une douille adaptable, par exemple, sur un outil non représenté, et qui comporte à cet effet du côté opposé à celui ouvert, une empreinte mâle 24 destinée à coopérer avec un outil de type classique.Referring now to Figures 2 and 3 it is possible to see a key 2 according to the invention, which in this case is in the form of an adaptable socket, for example, on a tool not shown, and which for this purpose has the opposite side to the open one, a male footprint 24 intended to cooperate with a tool of the conventional type.

La clé 2 comporte du côté ouvert une cavité 20 délimitée par une paroi interne 21 dans laquelle sont pratiqués des logements 22, dont la répartition angulaire est identique à celle des encoches 13, et chacun en forme d'une gorge longitudinale de section sensiblement semi-circulaire.The key 2 has on the open side a cavity 20 delimited by an inner wall 21 in which are formed housing 22, whose angular distribution is identical to that of the notches 13, and each in the form of a longitudinal groove of substantially semicircular section. circular.

En référence aux figures 4 et 5, on peut voir que la clé 2 selon l'invention comprend un insert 3 destiné à être introduit dans la cavité 20, lequel comporte une partie 30 de forme tubulaire qui présente à une extrémité et extérieurement une nervure périphérique 31, et à l'autre extrémité un plot cylindrique axial 32 destiné à s'insérer dans un trou borgne 25 pratiqué dans la clé 2, dans le fond de la cavité 20. Les dimensions de la cavité 20 et celles de l'insert 3 permettent que ce dernier puisse se déplacer axialement, étroitement et librement dans la cavité 20, le coulissement du plot 32 dans le trou borgne 25 assurant un guidage supplémentaire.With reference to Figures 4 and 5 it can be seen that the key 2 according to the invention comprises an insert 3 intended to be introduced into the cavity 20, which comprises a portion 30 of tubular shape which has at one end and externally a peripheral rib 31, and at the other end an axial cylindrical stud 32 for insertion into a blind hole 25 formed in the key 2, in the bottom of the cavity 20. The dimensions of the cavity 20 and those of the insert 3 allow the latter to move axially, tightly and freely in the cavity 20, the sliding of the stud 32 in the blind hole 25 providing additional guidance.

Chaque logement 22 est destiné à recevoir un doigt 23 de forme générale concordante cylindrique et d'une longueur inférieure à celle du logement en sorte d'être apte à s'y déplacer axialement.Each housing 22 is intended to receive a finger 23 of generally cylindrical concordant shape and of a length less than that of the housing so as to be able to move axially.

Les doigts 23 comportent une gorge périphérique 26 d'une largeur permettant d'accueillir étroitement le rebord périphérique 31 de l'insert 3, en sorte de s'y accrocher, et ainsi lier tous les doigts 23 au déplacement de l'insert 3.The fingers 23 comprise a peripheral groove 26 of a width that can closely accommodate the peripheral rim 31 of the insert 3, so as to hang on, and thus bind all the fingers 23 to the displacement of the insert 3.

Dans le mode de réalisation représenté, les doigts 23 sont emmanchés étroitement dans les logements 22 pratiqués entre cuir et chair, en sorte de ne pas pouvoir s'y mouvoir librement par gravité, mais uniquement sous l'effet d'une poussée axiale, tandis que l'insert 3 est lui-même retenu dans la cavité 20 au travers des doigts 23.In the embodiment shown, the fingers 23 are fitted tightly into the housings 22 made between leather and flesh, so as not to be able to move freely by gravity, but only under the effect of an axial thrust, while that the insert 3 is itself retained in the cavity 20 through the fingers 23.

On comprendra que l'insert 3 peut ainsi se déplacer axialement et prendre deux positions extrêmes rentrée et sortie. Dans la position sortie, celle représentée sur la figure 4, les doigts 23 peuvent coopérer avec les encoches 13 de la tête 11 de la vis antivol 1, tandis que dans la position rentrée, où chacun des doigts 23 est rétracté dans son logement 22, il n'y pas de coopération possible avec les encoches 13.It will be understood that the insert 3 can thus move axially and take two extreme positions in and out. In the outward position, that represented on the figure 4 , the fingers 23 can cooperate with the notches 13 of the head 11 of the anti-theft screw 1, while in the retracted position, where each of the fingers 23 is retracted into its housing 22, there is no possible cooperation with the notches 13.

En cas de tentative d'utilisation d'une clé 2 sur une vis 1 de code différent, au moins l'un des doigts 23 non en regard d'une encoche 13 est repoussé dans son logement 22 et entraîne les autres par l'intermédiaire de l'insert 3, rendant la clé inutilisable, et ceci d'autant plus si les doigts 23 ne peuvent pas revenir automatiquement en position sortie.In case of an attempt to use a key 2 on a screw 1 of different code, at least one of the fingers 23 not facing a notch 13 is pushed into its housing 22 and leads the others through of the insert 3, making the key unusable, and all the more so if the fingers 23 can not automatically return to the extended position.

On notera qu'il est prévu de limiter la pénétration de la tête 11 dans la cavité 20, afin d'empêcher la coopération des doigts 23 avec les encoches 13 lorsque l'insert 3 vient buter dans la cavité 20, ce qui est obtenu par la coopération en butée du bord extrême 27 de la douille 2 et de la tête 11 ou plus exactement d'un épaulement périphérique 14 de celle-ci.Note that it is intended to limit the penetration of the head 11 into the cavity 20, to prevent the engagement of the fingers 23 with the notches 13 when the insert 3 abuts in the cavity 20, which is obtained by the cooperation abutting the end edge 27 of the sleeve 2 and the head 11 or more exactly of a peripheral shoulder 14 thereof.

On notera de plus que la vis peut ne pas comporter d'épaulement périphérique, et que dans ce cas il peut être prévu que le bord extrême 27 de la douille 2 vienne buter directement sur l'objet à solidariser par vissage.Note further that the screw may not have a peripheral shoulder, and that in this case it may be provided that the end edge 27 of the sleeve 2 abuts directly on the object to be joined by screwing.
