Description

Dispositif de fixation antivol de solidarisation d'une roue sur le moyeu d'un véhicule automobile.  Anti-theft fastening device for fastening a wheel to the hub of a motor vehicle.
La présente invention a pour objet un dispositif de fixation antivol de solidarisation d'une roue sur le moyeu d'un véhicule automobile, comportant une partie distale filetée, une partie de maintien destinée à être appliquée contre la jante de la roue à fixer, et une partie proximale d'entraînement, destinée à être enfouie dans un puits de ladite jante, et qui permet la transmission à ladite partie filetée d'un couple de serrage ou de desserrage au travers d'une clé ou analogue, l'accouplement de la clé ou analogue avec ladite partie d'entraînement étant réalisé au travers d'empreintes concordantes que comportent d'une part ladite partie d'entraînement et d'autre part ladite clé ou analogue, les caractéristiques de forme, de dimensions et de positionnement desdites empreintes constituant un code. The present invention relates to an antitheft fastening device for securing a wheel on the hub of a motor vehicle, comprising a threaded distal portion, a holding portion intended to be applied against the rim of the wheel to be fixed, and a proximal driving portion, intended to be buried in a well of said rim, and which allows the transmission to said threaded portion of a tightening or loosening torque through a key or the like, the coupling of the key or the like with said driving part being made through concordant impressions which comprise on the one hand said drive part and on the other hand said key or the like, the shape, dimensions and positioning characteristics of said fingerprints constituting a code.
De manière habituelle 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 .  Usually 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 très fréquent pour chacune des roues, qu'au moins l'une des vis de fixation présente une tête qui nécessite une clef particulière pour pouvoir être manœuvrée .  In order to prevent a third party from fraudulently removing the wheels, it is very common for each of the wheels, that at least one of the fastening screws has a head which requires a special key to be able to be maneuvered.
On connaît ainsi de nombreux dispositifs de vis ou analogue munis de moyens de codage, comme par exemple ceux décrits dans les documents GB 2.006.371, F 2.359.730 et FR 2.567.215 et WO 03/081057. 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. L'inviolabilité de ces dispositifs est accrue lorsque la jante de la roue est munie de puits étroits et profonds destinés à l'enfouissement des têtes de vis, interdisant leur préhension par une approche latérale au moyen d'un outil de serrage. Numerous screw devices or the like are thus known, provided with coding means, for example those described in documents GB 2.006.371, FR 2.359.730 and FR 2.567.215 and WO 03/081057. 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. The inviolability of these devices is increased when the rim of the wheel is provided with narrow and deep wells for burying the screw heads, preventing their grip by a lateral approach by means of a clamping tool.
Dans ce cas de figure, les tentatives frauduleuses contre ces dispositifs sont pratiquées en force, soit par une attaque axiale et légèrement de biais avec un burin, soit en utilisant une clé présentant un autre code, ou une partie du code, et en la matriçant axialement contre la tête codée.  In this case, the fraudulent attempts against these devices are practiced in force, either by an axial attack and slightly biased with a burin, or by using a key presenting another code, or a part of the code, and by stamping it axially against the coded head.
La présente invention a pour but de proposer un dispositif de fixation antivol de solidarisation d'une roue sur le moyeu d'un véhicule automobile permettant de remédier cet inconvénient .  The object of the present invention is to propose an antitheft fastening device for fastening a wheel to the hub of a motor vehicle, making it possible to overcome this disadvantage.
Le dispositif de fixation antivol de solidarisation d'une roue sur le moyeu d'un véhicule automobile selon l'invention, comporte une partie distale filetée, une partie de maintien destinée à être appliquée contre la jante de la roue à fixer, et une partie proximale d'entraînement, destinée à être enfouie dans un puits de ladite jante, et qui permet la transmission à ladite partie filetée d'un couple de serrage ou de desserrage au travers d'une clé ou analogue, l'accouplement de la clé ou analogue avec ladite partie d' entraînement étant réalisé au travers d'empreintes concordantes que comportent d'une part ladite partie d'entraînement et d'autre part ladite clé ou analogue, les caractéristiques de forme, de dimensions et de positionnement desdites empreintes constituant un code, et il se caractérise en ce que :  The antitheft fastening device for fastening a wheel to the hub of a motor vehicle according to the invention comprises a threaded distal portion, a holding part intended to be applied against the rim of the wheel to be fixed, and a part proximal drive, intended to be buried in a well of said rim, and which allows the transmission to said threaded portion of a tightening torque or loosening through a key or the like, the coupling of the key or analogous with said driving portion being achieved through concordant impressions that comprise on the one hand said drive portion and on the other hand said key or the like, the shape, dimension and positioning characteristics of said fingerprints constituting a code, and it is characterized in that:
- ladite partie proximale d'entraînement est choisie pour présenter un diamètre proche de celui interne dudit puits,  said proximal drive portion is chosen to have a diameter close to that inside said well,
- lesdites empreintes que comporte ladite partie proximale d' entraînement sont réalisées sur le pourtour de celui-ci en regard de la paroi interne dudit puits lorsque ledit dispositif de fixation est en position de maintenir ladite roue, et elles sont de faible profondeur, - ladite partie proximale d' entraînement est surmontée d'un élément qui la couvre et qui est apte à y pivoter librement et axialement . said indentations that comprise said proximal drive portion are formed on the periphery thereof opposite the inner wall of said well when said fixing device is in position to maintain said wheel, and they are shallow, - said proximal drive portion is surmounted by an element which covers and which is able to pivot freely and axially.
Selon une caractéristique additionnelle du dispositif selon l'invention, les empreintes que comporte ladite partie proximale d'entraînement se présentent sous la forme d'une alternance, en périphérie, de zones en creux et en relief, et formant des créneaux répartis sur le pourtour de la partie proximale d'entraînement.  According to an additional characteristic of the device according to the invention, the indentations that comprise said proximal drive portion are in the form of an alternation, peripherally, of recessed areas and in relief, and forming slots distributed around the periphery of the proximal training part.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, les zones en relief forment un segment tronconique partiel, c'est-à-dire que la paroi extérieure de chacune d'elles est biseautée, inclinée en direction de l'extrémité proximale.  According to another additional feature of the device according to the invention, the raised areas form a partial frustoconical segment, that is to say that the outer wall of each of them is tapered, inclined towards the proximal end.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, chaque zone en relief présente au moins un bord latéral, celui sur lequel doit être exercé le couple de desserrage, qui est biseauté, c'est-à-dire incliné par rapport de la zone creuse adjacente.  According to another additional characteristic of the device according to the invention, each zone in relief has at least one lateral edge, that on which the loosening torque must be exerted, which is beveled, that is to say inclined relative to the adjacent hollow area.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, la partie proximale comporte un prolongement axial cylindrique, sur lequel est enfilé l'élément apte à y pivoter librement et axialement, qui comporte à cet effet un canal axial dont l'orifice extrême présente un chanfrein, tandis que la partie extrême dudit prolongement comporte un trou borgne axial qui, après mise en place dudit élément, est évasé au travers d'une opération de sertissage, de manière que la partie extrême s'étende dans le chanfrein.  According to another additional feature of the device according to the invention, the proximal portion comprises a cylindrical axial extension, on which is threaded the element able to pivot freely and axially, which comprises for this purpose an axial channel whose extreme orifice has a chamfer, while the end portion of said extension comprises an axial blind hole which, after placement of said element, is flared through a crimping operation, so that the end portion extends into the chamfer.
Les avantages et les caractéristiques du dispositif 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 device 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.
Dans le dessin annexé :  In the attached drawing:

- la figure 4 représente une vue en perspective d'un outil permettant de manœuvrer en serrage ou en desserrage le dispositif antivol selon l'invention.  - Figure 4 shows a perspective view of a tool for maneuvering in tightening or loosening the antitheft device according to the invention.
En référence aux figures 1 et 2, on peut voir un dispositif antivol 1 selon l'invention.  With reference to FIGS. 1 and 2, an antitheft device 1 according to the invention can be seen.
Ce dispositif antivol 1 comprend une partie distale 2 filetée destinée à traverser la jante de la roue à fixer à un moyeu, et à être vissée dans ce moyeu ; une partie intermédiaire 3, qui se présente sous la forme d'un disque et destinée à venir être appliquée contre la jante, et en l'occurrence associée à une rondelle 30; et une partie proximale d'entraînement 4, qui permet la transmission à ladite partie distale filetée 2 d'un couple de serrage ou de desserrage au travers d'un outil 5 tel que celui représenté à la figure 4.  This antitheft device 1 comprises a distal threaded portion 2 intended to pass through the rim of the wheel to be fixed to a hub, and to be screwed into this hub; an intermediate portion 3, which is in the form of a disc and intended to be applied against the rim, and in this case associated with a washer 30; and a proximal drive portion 4, which allows the transmission to said threaded distal portion 2 of a tightening or loosening torque through a tool 5 such as that shown in FIG. 4.
La partie proximale d'entraînement 4 consiste en un prolongement du disque consistant en la partie intermédiaire de maintien 3, dans la face périphérique 40 duquel prolongement sont pratiquées des encoches 41, qui forment une empreinte concordante avec le profil de l'outil 5, de manière permettre la transmission d'un couple. La face périphérique 40 consiste en une paroi de profil tronconique, dont le diamètre rétrécit plus il est proche de la partie proximale 4.  The proximal drive portion 4 consists of an extension of the disk consisting of the intermediate holding portion 3, in the peripheral face 40 of which are made notches 41, which form a recess matching the profile of the tool 5, way to allow the transmission of a couple. The peripheral face 40 consists of a frustoconical profile wall whose diameter narrows more closely to the proximal portion 4.
On notera que les encoches 41 sont réalisées par forgeage à froid, ce qui évite de recourir à des opérations complexes d' usinage .  Note that the notches 41 are made by cold forging, which avoids resorting to complex machining operations.
Les encoches 41 créent une alternance de zones en creux et de zones en relief 42, pour former des créneaux. Le nombre et la répartition non régulière des encoches 41, créent code. En référence plus particulièrement à la figure 2, on peut voir une jante 6 destinée à être fixée au travers de dispositifs antivol 1 selon l'invention, et plus exactement une partie de cette jante 6, qui comporte un trou 60 pour le passage de la partie distale filetée 2, ce trou 60 étant pratiqué dans le fond d'un puits 61 apte à permettre l'enfouissement de la partie intermédiaire de maintien 3 et de la partie proximale 4. The notches 41 create an alternation of recessed areas and raised areas 42, to form slots. The number and non-regular distribution of the notches 41, create code. Referring more particularly to Figure 2, we can see a rim 6 to be fixed through anti-theft devices 1 according to the invention, and more precisely a portion of the rim 6, which has a hole 60 for the passage of the threaded distal portion 2, this hole 60 being formed in the bottom of a well 61 adapted to allow the burial of the intermediate holding portion 3 and the proximal portion 4.
Les dimensions transversales de la partie proximale 4, et plus exactement au niveau de la face périphérique 40, sont très proches de celles internes du puits 61.  The transverse dimensions of the proximal portion 4, and more exactly at the peripheral face 40, are very close to those internal to the well 61.
Par ailleurs, les encoches 41 sont de faible profondeur dans le sens radial, en sorte l'espace qui s'étend entre le fond 43 d'une encoche 41 et la paroi interne 62 du puits 61, est étroit, en sorte de rendre impossible l'introduction dans le puits 61 d'un outil de serrage.  Furthermore, the notches 41 are shallow in the radial direction, so that the space which extends between the bottom 43 of a notch 41 and the inner wall 62 of the well 61, is narrow, so as to make it impossible introducing into the well 61 a clamping tool.
D'autre part, chaque zone en relief 41 présente deux bords latéraux 44 biseautés, à savoir qu'ils ne s'étendent pas dans des plans radiaux, mais sont inclinés par rapport aux fonds 43 des encoches 41 adjacentes.  On the other hand, each raised area 41 has two beveled side edges 44, that is, they do not extend in radial planes, but are inclined relative to the bottoms 43 of the adjacent slots 41.
D'autre part encore, la partie proximale 4 est surmontée d'un élément 7 en l'occurrence en forme de bague, apte à pouvoir pivoter axialement de manière libre .  On the other hand, the proximal portion 4 is surmounted by an element 7 in this case in the form of a ring, able to pivot axially freely.
En référence également aux figures 3a, 3b et 3c on peut voir que la partie proximale 4 comporte un prolongement axial cylindrique 45, sur lequel est enfilé l'élément 7 par l'intermédiaire d'un canal axial 70 dont l'orifice extrême présente un chanfrein 71. La partie extrême 46 du prolongement 45 comporte un trou borgne axial 47 qui, après mise en place de l'élément 7 (figure 3b), est évasé (figure 3c) au travers d'une opération de sertissage, de manière que la partie extrême 46 s'étende dans le chanfrein 71, en sorte de réaliser le maintien, avec possibilité de pivotement axial, de l'élément 7.  With reference also to FIGS. 3a, 3b and 3c, it can be seen that the proximal portion 4 has a cylindrical axial extension 45 on which the element 7 is threaded via an axial channel 70 whose end orifice has a 71. The end portion 46 of the extension 45 comprises an axial blind hole 47 which, after placement of the element 7 (FIG. 3b), is flared (FIG. 3c) through a crimping operation, so that the end part 46 extends in the chamfer 71, so as to carry out the holding, with the possibility of axial pivoting, of the element 7.
En référence maintenant à la figure 4 on peut voir un outil ou clé 5, permettant le manœuvrement du dispositif antivol 1. Cette clé 5 se présente sous la forme d'un embout dont une extrémité 50 est conformée pour permettre son adaptation à un outil, en l'occurrence cette extrémité est, non limitativement , de forme hexagonale, et dont l'autre extrémité consiste en un manchon cylindrique 51, dont le bord extrême est découpé pour former une alternance de créneaux 52 et de dents 53, de manière complémentaire aux créneaux que forment les zones en creux 41 et les zones en relief 42. Referring now to Figure 4 we can see a tool or key 5, allowing the maneuvering of the antitheft device 1. This key 5 is in the form of a tip having an end 50 is shaped to allow its adaptation to a tool, in this case this end is, not limited to, hexagonal shape, and the other end consists of a cylindrical sleeve 51, the end edge is cut to form an alternation of crenellations 52 and teeth 53, so complementary to the slots formed by the hollow zones 41 and the relief zones 42.
On comprendra que le nombre, la répartition et la forme des zones en creux 41 constituent un code difficile à contourner, d'autant plus que la partie proximale 4 est enfouie au fond du puits 61, et que cela rend difficile la lecture de ce code .  It will be understood that the number, the distribution and the shape of the recessed areas 41 constitute a code that is difficult to circumvent, especially since the proximal portion 4 is buried at the bottom of the well 61, and that makes it difficult to read this code. .
Le fait que le diamètre de la partie proximale 4 et celui interne du puits 61 soient très proches, et que les zones en creux 41 soient de faible profondeur, rend impossible le saisissement du dispositif antivol 1 au moyen d'outil de serrage, d'autant plus que le saisissement de l'élément 7 est tout aussi inopérant puisqu'il tourne librement.  The fact that the diameter of the proximal portion 4 and the inner diameter of the well 61 are very close, and that the recessed areas 41 are shallow, makes it impossible to grip the antitheft device 1 by means of a clamping tool. as much as the seizing of element 7 is just as inoperative since it turns freely.
La forme des zones en relief 42, essentiellement les inclinaisons de la face 40 et des bords 44, empêche la transmission d'un couple au moyen d'une clé universelle, fabriquée pour l'occasion et ne comportant qu'une seule dent 53, laquelle ne pourrait qu'échapper lors d'une tentative d' entraînement .  The shape of the raised areas 42, essentially the inclinations of the face 40 and the edges 44, prevents the transmission of a torque by means of a universal key, manufactured for the occasion and having only one tooth 53, which could only escape during a training attempt.
Le pivotement libre de l'élément 7, empêche la mise en rotation du dispositif antivol 1 au moyen d'un burin.  The free pivoting of the element 7 prevents rotation of the antitheft device 1 by means of a chisel.
On notera également qu'il peut être envisagé d'utiliser une clé 5 d'un code donné pour forcer par sertissage une vis d'un autre code. Pour pallier ce problème, il est peut être avantageux que les vis soient traitées et dimensionnées pour casser lors d'une telle tentative de sertissage.  Note also that it may be envisaged to use a key 5 of a given code to force by crimping a screw of another code. To overcome this problem, it may be advantageous for the screws to be processed and dimensioned to break during such a crimping attempt.
