Sur toutes les figures, les éléments identiques portent les mêmes numéros de référence. La face avant du verrou est désignée par l'extrémité du verrou accessible par l'utilisateur depuis l'extérieur du véhicule automobile.In all the figures, the identical elements bear the same reference numbers. The front face of the lock is designated by the end of the lock accessible by the user from outside the motor vehicle.

Les figures 1, 2 et 3 illustrent un antivol à verrou insérable, destiné à être monté dans un véhicule automobile pour en sécuriser la direction. L'antivol comporte un corps de réception, 1, qui est un corps d'antivol selon le mode de réalisation illustré, présentant une première portion dans laquelle sont intégrés des moyens de verrouillage destinés à bloquer un élément mobile de la direction (non visibles). Le corps d'antivol 1 est également pourvu d'une seconde portion à l'intérieur de laquelle un verrou 2 est destiné à être inséré et solidarisé. Le verrou 2 comporte un stator 3 à l'intérieur duquel un rotor 4 est monté pour commander la mise en oeuvre des moyens de verrouillage, via un élément de liaison (non représenté). L'élément de liaison présente une extrémité conformée de manière à pouvoir s'emboîter dans une cavité correspondante à l'arrière du verrou 2 et ainsi coopérer par entraînement avec la partie rotor 4 du verrou 2.The figures 1 , 2 and 3 illustrate an insert lockable lock, intended to be mounted in a motor vehicle to secure the direction. The antitheft device comprises a receiving body, 1, which is an antitheft body according to the illustrated embodiment, having a first portion in which are integrated locking means for blocking a movable element of the direction (not visible) . The antitheft body 1 is also provided with a second portion inside which a latch 2 is intended to be inserted and secured. The latch 2 comprises a stator 3 inside which a rotor 4 is mounted to control the implementation of the locking means, via a connecting element (not shown). The connecting element has a shaped end so as to be able to fit into a cavity corresponding to the rear of the latch 2 and thus cooperate by driving with the rotor part 4 of the latch 2.

Le rotor 4 est susceptible d'être mobile en rotation selon l'axe longitudinal I-I à l'intérieur du stator 3 lorsque la clé conforme au verrou 2 est insérée dans le rotor 4 par l'entrée de clé 6 ménagée à l'extrémité avant du rotor 4, de manière à décondamner le système de verrouillage du véhicule automobile.The rotor 4 is able to be rotatable along the longitudinal axis II inside the stator 3 when the key according to the latch 2 is inserted into the rotor 4 by the keyway 6 provided at the front end. of the rotor 4, so as to unlock the locking system of the motor vehicle.

Il est entendu que, dans l'ensemble de ce texte, le terme rotor désigne très généralement tout sous-ensemble comprenant un corps de rotor à travers lequel sont ménagés des fentes radiales à même de recevoir des paillettes qui sont assemblées mobiles en translation radiale et qui sont couplées à des ressorts de rappel les entraînant en permanence dans des positions saillantes par rapport au corps du rotor.It will be understood that, throughout the text, the term "rotor" designates very generally any subassembly comprising a rotor body through which radial slots are formed capable of receiving flakes which are assembled in radial translation and which are coupled to return springs permanently driving them into protruding positions with respect to the rotor body.

Le stator de verrou 3 présente en outre un moyen de fixation au corps d'antivol 1, pour solidariser le verrou 2 avec le corps d'antivol 1. Selon un exemple de réalisation représenté, ce moyen de fixation présente un plot élastique 8, par exemple monté sur ressort, implanté à la surface du stator 3 du verrou 2, coopérant avec un orifice correspondant 9, de forme sensiblement complémentaire au plot 8, ménagé à l'intérieur de la seconde portion du corps d'antivol 1.The latch stator 3 furthermore has a fastening means to the antitheft body 1, for securing the latch 2 with the antitheft body 1. According to an exemplary embodiment shown, this fastening means has an elastic stud 8, for spring-loaded example, implanted on the surface of the stator 3 of the latch 2, cooperating with a corresponding orifice 9, of substantially complementary shape to the stud 8, formed inside the second portion of the antitheft body 1.

Le verrou 2 comporte un cache 10 destiné à être fixé en face avant du stator 3. Le cache 10 présente une ouverture circulaire 14 pour rendre accessible l'entrée de clé 6 ménagée à l'extrémité avant du rotor 4. Le cache 10 est réalisé en un matériau résistant à l'arrachement, par exemple en matériau de type Zamak, le Zamak étant un alliage à base de zinc, aluminium et magnésium avec parfois du cuivre.The latch 2 comprises a cover 10 intended to be fixed on the front face of the stator 3. The cover 10 has a circular opening 14 to make accessible the key inlet 6 formed at the front end of the rotor 4. The cover 10 is made in a material resistant to tearing, for example Zamak type material, Zamak being an alloy based on zinc, aluminum and magnesium with sometimes copper.

Le verrou 2 est implanté dans le corps d'antivol 1 de telle sorte que l'entrée de clé 6 soit accessible depuis l'extérieur du véhicule automobile.The latch 2 is located in the antitheft body 1 so that the keyway 6 is accessible from outside the motor vehicle.

Le verrou 2 comporte un moyen anti-arrachement porté par le cache 10 et le stator 3 pour fixer le cache 10 au stator 3 et retenir axialement le rotor 4 dans le stator 3. La présence d'un moyen anti-arrachement est indispensable pour assurer l'intégrité du rotor 4 du verrou 2, notamment vis-à-vis d'éventuelles tentatives d'effraction par arrachage ou défoncement du rotor 4.The lock 2 comprises an anti-tearing means carried by the cover 10 and the stator 3 to fix the cover 10 to the stator 3 and axially retain the rotor 4 in the stator 3. The presence of an anti-pullout means is essential to ensure the integrity of the rotor 4 of the lock 2, in particular with respect to possible attempts of break-in by tearing or breaking of the rotor 4.

Le moyen anti-arrachement est configuré pour bloquer axialement le cache 10 sur le stator 3 par le positionnement du cache 10 sur le stator 3 et son pivotement consécutif sur ledit stator 3 dans la position assemblée représenté sur la figure 1D. Le montage peut ainsi être réalisé manuellement de sorte qu'aucun outil spécifique ou poste de montage n'est nécessaire. Il en résulte une diminution significative des coûts de production et de montage.The anti-tearing means is configured to axially block the cover 10 on the stator 3 by positioning the cover 10 on the stator 3 and its subsequent pivoting on said stator 3 in the assembled position shown in FIG. figure 1D . The assembly can thus be performed manually so that no specific tool or mounting station is necessary. This results in a significant decrease in production and assembly costs.

L'insertion du verrou 2 dans le corps d'antivol 1 verrouille ensuite définitivement la rotation du cache 10. Pour cela, le corps d'antivol 1 comporte un moyen anti-dévissement du cache 10 sur le stator 3.The insertion of the latch 2 in the antitheft body 1 then permanently locks the rotation of the cover 10. For this purpose, the antitheft body 1 comprises an anti-unscrewing means of the cover 10 on the stator 3.

Selon le mode de réalisation préféré, le cache 10 est fixé au stator 3 par un montage de type baïonnette, c'est-à-dire que le cache 10 est posé sur le stator 3 et est pivoté pour être retenu en position de blocage axial. Le montage baïonnette forme un moyen anti-arrachement, en mesure de bloquer, en translation axiale, le rotor 4 à l'intérieur du stator 3 lorsque le verrou 2 est fixé à l'intérieur de l'antivol 1. La tenue du verrou face à l'enfoncement ou à l'arrachement du rotor est ainsi augmentée par le montage de type baïonnette qui permet une meilleure tenue à l'arrachement.According to the preferred embodiment, the cover 10 is fixed to the stator 3 by a bayonet type mounting, that is to say that the cover 10 is placed on the stator 3 and is pivoted to be retained in axial locking position . The bayonet mount forms an anti-tearing means, able to block, in axial translation, the rotor 4 inside the stator 3 when the lock 2 is fixed inside the lock 1. The holding of the lock face the driving or tearing of the rotor is thus increased by the bayonet type mounting which allows a better resistance to tearing.

Selon un mode de réalisation préféré, le stator 3 présente une nervure 22 de plan général perpendiculaire à l'axe longitudinal I-I et la bordure du cache 10 présente un crochet correspondant 23. Le crochet 23 coopère avec la nervure 22 pour retenir axialement le cache 10.According to a preferred embodiment, the stator 3 has a rib 22 of general plane perpendicular to the longitudinal axis II and the edge of the cover 10 has a corresponding hook 23. The hook 23 cooperates with the rib 22 to axially retain the cover 10 .

Par ailleurs, le cache comporte une nervure longitudinale 24 d'anti-dévissement destinée à coopérer avec un logement 32 ménagé à proximité de l'embouchure du corps d'antivol 1.Furthermore, the cover comprises a longitudinal rib 24 anti-unwinding intended to cooperate with a housing 32 formed near the mouth of the body of the lock 1.

Le verrou 2 comporte en outre un élément de rattrapage de jeu longitudinal 15 en matière plastique. Cet élément de rattrapage de jeu 15 permet de rattraper les éventuels jeux pouvant exister entre le cache 10 et le stator 3 de verrou 2 et ainsi, de supprimer le bruit occasionné par un mouvement relatif entre le cache 10 et le stator 3 lors du transport du verrou 2 sur la ligne de montage véhicule ainsi qu'une fois monté dans l'antivol. L'élément de rattrapage de jeu 15 présente par exemple une forme générale en bande et comporte des moyens d'assemblage au stator 3.The latch 2 further comprises a longitudinal play compensator 15 made of plastic. This play-catching element makes it possible to make up any games that may exist between the cover 10 and the latch stator 3 and thus eliminate the noise caused by a relative movement between the cover 10 and the stator 3 during the transport of the lock 2 on the vehicle assembly line and once mounted in the lock. The play-catching element 15 has, for example, a generally strip-like shape and comprises means of assembly to the stator 3.

L'élément de rattrapage de jeu 15 peut être fixé par encliquetage au stator 3 de verrou 2. Il comporte un pontet 18 élastique, par exemple, formé par une bande courbée, pour rattraper les tolérances de jeux, une patte longitudinale 16 portée par cet élément venant en butée contre le cache.The play-catching element 15 may be snap-fastened to the latch stator 3. It comprises an elastic bridge 18, for example, formed by a curved strip, to make up the play tolerances, a longitudinal lug 16 carried by this element abutting against the cache.

Selon l'invention, le verrou comporte également un moyen de blocage en rotation du cache 10 constitué d'une pièce 30 intercalée entre le cache 10 et la face avant du stator 3.According to the invention, the lock also comprises means for locking the cover 10 in rotation, consisting of a part 30 interposed between the cover 10 and the front face of the stator 3.

Selon le mode de réalisation illustré, cette pièce 30 et en forme de coupelle à fond ouvert et constitue un cache intermédiaire visible sur les figures 1A et 1B est représenté seul sur les figures 5A et 5B. Cette pièce 30 a alors également une fonction de blindage d'inviolabilité du rotor, en plus de sa fonction de blocage en rotation du cache 10, grâce à sa paroi frontale ouverte ou fond ouvert 30A qui vient recouvrir partiellement la face avant du rotor.According to the illustrated embodiment, this piece 30 and cup-shaped open bottom and is an intermediate cache visible on the Figures 1A and 1B is represented alone on the Figures 5A and 5B . This piece 30 then also has a tamper-proof function of the rotor, in addition to its locking function in rotation of the cover 10, with its open front wall or open bottom 30A which partially covers the front face of the rotor.

Ce cache intermédiaire 30 de forme cylindrique et avantageusement en acier, éventuellement inoxydable, comporte un moyen de solidarisation en rotation avec la face avant du stator 3 et un moyen de blocage en rotation du cache 10 actif dans la position assemblée représenté sur les figures 1D et 3.This intermediate cap 30 of cylindrical shape and advantageously made of steel, possibly stainless, comprises means for securing in rotation with the front face of the stator 3 and a means for locking in rotation of the active cover 10 in the assembled position shown in the Figures 1D and 3 .

Le cache intermédiaire comporte une bride annulaire périphérique 31 comportant au moins une patte élastique inclinée vers l'avant 32, 33 en position de repos, formant ce moyen de blocage, et destinée à coopérer avec des rainures 10A, 10B visibles sur les figures 4A et 4B et portée par la face arrière du cache 10, dans ladite position assemblée. Selon l'exemple représenté, ces pattes sont au nombre de deux ainsi que les rainures correspondantes.The intermediate cover comprises a peripheral annular flange 31 comprising at least one resilient lug forward 32, 33 in the rest position, forming this locking means, and intended to cooperate with grooves 10A, 10B visible on the Figures 4A and 4B and carried by the rear face of the cover 10, in said assembled position. According to the example shown, these tabs are two in number and the corresponding grooves.

La bride annulaire 31 du cache intermédiaire comporte au moins une rainure, ici deux rainures 34, 35, d'emboîtement longitudinal avec une nervure, ici deux nervures 36, 37, porté(es) par la face avant du stator, formant le moyen de solidarisation.The annular flange 31 of the intermediate cover comprises at least one groove, here two grooves 34, 35, longitudinal interlocking with a rib, here two ribs 36, 37, carried (es) by the front face of the stator, forming the means of joining.

L'assemblage d'un verrou 2 conforme à l'invention s'effectue de la façon suivante.The assembly of a lock 2 according to the invention is carried out as follows.

Comme illustré sur les figures 1A et 1B, le cache intermédiaire 30 est disposé sur la face avant du stator 3, par emboîtement des nervures 36, 37 de ce dernier dans les rainures 34, 35 portées par ce cache intermédiaire. Dans cette position, les pattes élastiques 32, 33 sont en position de repos, inclinées vers l'avant.As illustrated on Figures 1A and 1B , the intermediate cover 30 is disposed on the front face of the stator 3, by interlocking the ribs 36, 37 of the latter in the grooves 34, 35 carried by the intermediate cover. In this position, the elastic tabs 32, 33 are in the rest position, inclined forwardly.

Le cache 10 est ensuite appliqué sur ce cache intermédiaire 30, comme illustré sur la figure 1C, les pattes élastiques 32, 33 étant comprimées et sollicitées en position non inclinées comme illustré sur la figure 4A et le crochet 23 du cache 10 étant disposé en face de la nervure 22 du stator 3.The cover 10 is then applied to this intermediate cover 30, as illustrated on the figure 1C , the resilient tabs 32, 33 being compressed and urged in a non-inclined position as illustrated in FIG. Figure 4A and the hook 23 of the cover 10 being arranged in front of the rib 22 of the stator 3.

Le cache est enfin pivoté, pour venir emboîter le crochet 23 sur la nervure 22, comme représenté sur la figure 1D où le verrou est en position assemblée. Les pattes élastiques 32, 33 du cache intermédiaire 30 sont alors libérées en position inclinées dans les nervures 10A, 10B du cache 10, bloquant ce dernier en rotation.The cover is finally pivoted to engage the hook 23 on the rib 22, as shown in FIG. figure 1D where the lock is in the assembled position. The elastic tabs 32, 33 of the intermediate cover 30 are then released in inclined position in the ribs 10A, 10B of the cover 10, blocking the latter in rotation.

Ce verrou assemblé peut alors être inséré dans le corps de verrou 1 représenté sur la figure 2 où la rotation du cache 10 est verrouillée définitivement par emboîtement de la nervure longitudinale 24 d'anti-dévissement du cache dans le logement 32 du corps de verrou.This assembled lock can then be inserted into the lock body 1 shown in the figure 2 where the rotation of the cover 10 is locked permanently by interlocking the longitudinal rib 24 anti-unwinding of the cover in the housing 32 of the lock body.

Il est décrit ci-dessus un mode de réalisation préféré de l'invention mais l'invention définie par les revendications annexées englobe également d'autres modes de réalisation de la pièce 30 de blocage en rotation du cache.A preferred embodiment of the invention is described above, but the invention defined by the appended claims also encompasses other embodiments of the cache rotational locking member.

La fonction d'inviolabilité peut être assurée uniquement par le cache 10 et la pièce 30 être de forme semi cylindrique. Cette pièce peut alors être dépourvue de paroi frontale 30A.The inviolability function can be provided only by the cover 10 and the part 30 be of semi-cylindrical shape. This piece can then be devoid of front wall 30A.

Elle peut même être dépourvue de bride annulaire périphérique 31, et être constitué d'une simple couronne cylindrique. Ledit moyen de blocage peut être alors constitué d'au moins une patte élastique inclinée sur et par rapport à la paroi cylindrique de cette pièce, en position de repos, et destinée à coopérer chacune avec une rainure radiale portée par la face arrière dudit cache, dans ladite position assemblée. De même, ledit moyen de solidarisation peut être alors toujours constitué d'au moins une rainure d'emboîtement longitudinal, agencé à l'extrémité de cette paroi cylindrique, avec une nervure portée par la face avant du stator, formant ledit moyen de solidarisation. Dans ce cas, la pièce ne jouant pas de rôle de blindage, elle peut être en matière plastique.It may even be devoid of a peripheral annular flange 31, and consist of a simple cylindrical crown. Said locking means may then consist of at least one elastic tab inclined on and with respect to the cylindrical wall of this part, in the rest position, and intended to cooperate each with a radial groove carried by the rear face of said cover, in said assembled position. Similarly, said securing means may then always consist of at least one longitudinal interlocking groove, arranged at the end of this cylindrical wall, with a rib carried by the front face of the stator, forming said securing means. In this case, the piece does not play a shielding role, it can be plastic.

De façon générale, ledit moyen de blocage est constitué d'au moins une patte élastique inclinée en position de repos et destinée à coopérer chacune avec une rainure portée par la face arrière dudit cache (10), dans ladite position assemblée. Et ledit moyen de solidarisation est constitué d'au moins une rainure d'emboîtement longitudinal avec une nervure portée par la face avant du stator (3), formant ledit moyen de solidarisation.In general, said locking means consists of at least one resilient tab inclined in the rest position and intended to cooperate each with a groove carried by the rear face of said cover (10), in said assembled position.
