La figure 1 illustre un exemple de réalisation dans lequel le 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 lock stator 3 furthermore has a fastening means to the antitheft body 1, for securing the lock 2 with the antitheft body 1. FIG. 1 illustrates an exemplary embodiment in which the fastening means has an elastic stud 8, for example mounted on a spring, implanted on the surface of the stator 3 of the latch 2, cooperating with a corresponding orifice 9, of a shape substantially complementary 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. Mieux visible sur la figure 2, le cache 10 présente par exemple un palier interne 1 1 présentant une bordure périphérique externe 12, prévu pour recevoir une collerette 13 correspondante de la face avant du stator 3. Le cache 10 présente en outre une ouverture circulaire 14 pour rendre accessible l'entrée de clef 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 est un alliage à base de zinc, aluminium et magnésium avec parfois du cuivre).The lock 2 comprises a cover 10 intended to be fixed on the front face of the stator 3. Better visible in FIG. 2, the cover 10 has, for example, an internal bearing 1 1 having an external peripheral edge 12, designed to receive a corresponding collar 13 of the front face of the stator 3. The cover 10 also 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 of a material resistant to tearing for example Zamak type material (Zamak is 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 des moyens anti-arrachements s'avère 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 latch 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 the anti-tearing 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. 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 block axially the cover 10 on the stator 3 by positioning the cover 10 on the stator 3 and its subsequent pivoting on said stator 3. 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 locks the rotation of the cover 10 permanently. For this reason, the antitheft body 1 comprises an anti-unscrewing means of the cover 10 on the stator 3.
On prévoit en outre que le moyen anti-arrachement est configuré pour coopérer avec un moyen anti-dévissement du corps d'antivol 1 pour verrouiller la rotation du cache 10 dans le corps d'antivol 1.It is furthermore provided that the anti-tearing means is configured to cooperate with anti-loosening means of the anti-theft body 1 to lock the rotation of the cover 10 in the anti-theft body 1.
Par exemple, le cache 10 est fixé au stator 3 par un montage baïonnette, c'est-à-dire que le cache 10 est posé sur le stator 3 et pivote 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 baïonnette qui permet une meilleure tenue à l'arrachement.For example, the cover 10 is fixed to the stator 3 by a bayonet mounting, that is to say that the cover 10 is placed on the stator 3 and pivots to be retained in the 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 bayonet mounting which allows a better resistance to tearing.
Selon une réalisation, la collerette 13 de la face avant du stator 3 présente par exemple au moins deux évidements 22 et la bordure 12 du cache 10 présente deux crochets radiaux correspondants 23. Les crochets 23 coopèrent avec les évidements 22 pour retenir axialement le cache 10 par la collerette 13. Pour un meilleur assemblage, les évidements 22 et les crochets 23 sont disposés de manière diamétralement opposée respectivement sur la collerette 13 et la bordure 12. Les évidements 22 présentent par exemple respectivement un premier décrochement 22a pour le passage axial du crochet correspondant 23 et un deuxième décrochement 22b pour guider le cache 10 en rotation et retenir axialement le crochet 23. Les crochets 23 présentent en outre des butées latérales 24 pour stopper la rotation du cache 10 en fin de course. Les crochets radiaux 23 du moyen anti-arrachement sont en outre destinés à coopérer avec des logements 32 correspondant du moyen anti-dévissement.According to one embodiment, the flange 13 of the front face of the stator 3 has for example at least two recesses 22 and the edge 12 of the cover 10 has two corresponding radial hooks 23. The hooks 23 cooperate with the recesses 22 to axially retain the cover 10 by the collar 13. For a better assembly, the recesses 22 and the hooks 23 are arranged diametrically opposite respectively on the flange 13 and the edge 12. The recesses 22 have for example respectively a first recess 22a for the axial passage of the hook corresponding 23 and a second recess 22b to guide the cover 10 in rotation and axially retain the hook 23. The hooks 23 further have lateral stops 24 to stop the rotation of the cover 10 at the end of the race. The radial hooks 23 of the anti-tearing means are further intended to cooperate with corresponding housings 32 of the anti-loosening means.
A cet effet, le moyen anti-dévissement de l'antivol comporte par exemple deux logements latéraux 32, ménagés à proximité de l'embouchure du corps d'antivol 1 , diamétralement opposés et conformés pour recevoir les crochets radiaux correspondants 23 du cache 10 et les bloquer en rotation (figure 1 ).For this purpose, the anti-loosening means of the antitheft device comprises, for example, two lateral housings 32, formed near the mouth of the anti-theft body 1, diametrically opposite and shaped to receive the corresponding radial hooks 23 of the cover 10 and block them in rotation (figure 1).
Ainsi, les crochets 23 du montage baïonnette présentent, en plus de la fonction anti- arrachement du rotor, une fonction anti-dévissement du cache 10 lorsque le verrou 2 est inséré dans le corps d'antivol 1.Thus, the hooks 23 of the bayonet assembly have, in addition to the anti-tearing function of the rotor, an anti-loosening function of the cover 10 when the latch 2 is inserted into the antitheft body 1.
Le verrou 2 comporte en outre un élément de blocage en rotation 15 du cache 10 sur le stator 3. En plus du blocage en rotation du cache 10, l'élément de blocage en rotation 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.The latch 2 further comprises a rotational locking element 15 of the cover 10 on the stator 3. In addition to the rotational locking of the cover 10, the rotational locking element 15 makes it possible to make up any games that may exist between the cover 10 and the latch stator 3 and thus, to 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 .
L'élément de blocage en rotation 15 présente par exemple une forme générale en bande et comporte des moyens d'assemblage au stator 3 et au cache 10.The rotational locking element 15 has, for example, a generally strip-like shape and comprises means for assembling the stator 3 and the cover 10.
On prévoit par exemple que l'élément de blocage en rotation 15 présente une patte d'accrochage 16 destinée à coopérer avec la bordure 12 du cache 10. Ainsi l'élément de blocage en rotation 15 peut verrouiller le montage baïonnette par la position angulaire relative du cache 10 par rapport au stator 3 de sorte qu'un même mouvement manuel de rotation du cache 10 permet de fixer le cache 10 au stator 3 et de bloquer la rotation du cache 10.For example, the rotational locking element 15 has a hooking lug 16 intended to cooperate with the edge 12 of the cover 10. Thus, the rotational locking element 15 can lock the bayonet fitting by the relative angular position. of the cover 10 with respect to the stator 3 so that a same manual rotation of the cover 10 makes it possible to fix the cover 10 to the stator 3 and to block the rotation of the cover 10.
Selon un premier mode de réalisation illustré en figure 2, ladite patte d'accrochage 16 s'étend radialement vers une encoche correspondante 17 prévue dans ladite bordure 12 du cache 10 de sorte que l'élément de blocage 15 puisse être monté sur le verrou postérieurement au cache 10. L'élément de blocage en rotation 15 peut être fixé par encliquetage au stator 3 de verrou 2. On prévoit par exemple que l'élément de blocage en rotation 15 s'étend sur le stator 3 de verrou 2 sensiblement parallèlement à l'axe de rotation l-l du rotor 4 de verrou 2 et présente une première P1 et une deuxième P2 parties destinées à coopérer lesdites extrémités longitudinales correspondantes du stator 3 de verrou 2. Les première et deuxième parties P1 , P2 sont raccordées par un pontet 18 de l'élément de blocage en rotation 15. On prévoit un pontet 18 élastique, par exemple, formé par une bande courbée, pour rattraper les tolérances de jeux.According to a first embodiment illustrated in FIG. 2, said hooking tab 16 extends radially towards a corresponding notch 17 provided in said rim 12 of the cover 10 so that the locking element 15 can be mounted on the lock subsequently. to the cache 10. The rotational locking element 15 may be snap-fastened to the latch stator 3. For example, it is provided that the rotational locking element 15 extends over the latch stator 3 substantially parallel to the latch axis. rotation 11 of the rotor 4 lock 2 and has a first P1 and a second P2 parts for cooperating with said corresponding longitudinal ends of the stator 3 lock 2. The first and second parts P1, P2 are connected by a bridge 18 of the element Rotational lock 15. An elastic bridge 18 is provided, for example, formed by a curved strip, to make up the play tolerances.
Dans l'exemple représenté en figure 2, l'élément de blocage en rotation 15 présente la forme générale d'une bande s'étendant sur le stator 3 présentant une première partie P1 à l'arrière du verrou, un pontet 18 et une deuxième partie P2 à l'avant du verrou 2. Par exemple, la première partie P1 présente deux premiers bras élastiques d'encliquetage 19 disposés de part et d'autre de ladite bande centrale et un troisième bras élastique d'encliquetage disposé à l'arrière dudit stator de verrou. Les bras élastiques d'encliquetage 19 sont destinés à coopérer avec une rainure correspondante 20 prévue dans le stator 3 de verrou 2. La première partie P1 présente en outre un trou traversant 21 pour le passage du plot élastique 8 du moyen de fixation du stator 3. La deuxième partie P2 disposée à l'avant du verrou 2 présente deux bras élastiques d'encliquetage 19 disposés de part et d'autre de la bande centrale, ladite bande centrale se prolongeant vers l'avant du verrou 2 par la patte d'accrochage 16.In the example represented in FIG. 2, the rotational locking element 15 has the general shape of a strip extending on the stator 3 having a first portion P1 at the rear of the lock, a trigger guard 18 and a second P2 portion to the front of the latch 2. For example, the first portion P1 has two first resilient snap arms 19 disposed on either side of said central strip and a third resilient snap arm disposed at the rear said latch stator. The resilient snap arms 19 are intended to cooperate with a corresponding groove 20 provided in the latch stator 3. The first portion P1 furthermore has a through-hole 21 for the passage of the elastic stud 8 of the stator fixing means 3. The second part P2 disposed at the front of the latch 2 has two resilient snap arms 19 arranged on either side of the central strip, said central strip extending towards the front of the latch 2 by the lug of hanging 16.
On prévoit par exemple un élément de blocage en rotation 15 en matériau plastique.For example, a rotational locking element 15 made of plastics material is provided.
Pour faciliter le montage, on prévoit que la bordure 12 du cache 10 présente deux encoches 17 diamétralement opposées et à équidistance des deux crochets 23. Ainsi, le cache 10 présente un axe de symétrie permettant de définir deux positions angulaires du cache 10 dans lequel le cache 10 est fixé au stator 3 et verrouillé en rotation.To facilitate assembly, provision is made for the edge 12 of the cover 10 to have two notches 17 that are diametrically opposite and equidistant from the two hooks 23. Thus, the cover 10 has an axis of symmetry making it possible to define two angular positions of the cover 10 in which the cover 10 is fixed to the stator 3 and locked in rotation.
Au cours du montage du verrou 2, on commence par monter le cache 10 sur le stator 3 de verrou 2 (voir flèche 25 sur la figure 2). Pour cela, les crochets 23 du cache 10 sont insérés dans les premiers décrochements 22a des évidements 22. Puis, dans une deuxième étape, on fait pivoter le cache 10 sur la collerette 13 pour retenir axialement le cache 10 par la collerette 13 par les deuxième décrochements jusqu'à ce que leurs extrémités viennent en butée sur les crochets 23 (flèche 26).During assembly of the latch 2, we first mount the cover 10 on the stator 3 lock 2 (see arrow 25 in Figure 2). For this, the hooks 23 of the cover 10 are inserted into the first recesses 22a of the recesses 22. Then, in a second step, the cover 10 is pivoted on the collar 13 to axially retain the cover 10 by the flange 13 by the second recesses until their ends abut on the hooks 23 (arrow 26).
Et, dans une troisième étape, on fixe par encliquetage l'élément de blocage en rotation 15 au stator 3 de verrou 2 (flèche 27). La patte d'accrochage 16 coopère alors avec l'encoche 17 verrouillant la rotation du cache 10.And, in a third step, the rotational locking element 15 is fixed by snap-fastening to the latch stator 3 (arrow 27). The hooking lug 16 then cooperates with the notch 17 locking the rotation of the cover 10.
Selon un deuxième mode de réalisation représenté sur les figures 6 et 7, ladite patte d'accrochage 16 s'étend latéralement vers une attache correspondante 28 prévue dans ladite bordure 12 du cache 10 de sorte que ledit cache 10 puisse être monté sur le verrou postérieurement audit élément de blocage 15.According to a second embodiment shown in FIGS. 6 and 7, said hooking tab 16 extends laterally to a corresponding fastener 28 provided in said edge 12 of the cover 10 so that said cover 10 can be mounted on the lock later. to said blocking element 15.
Lors du montage du verrou 2, on commence donc par fixer l'élément de blocage en rotation 15 par encliquetage au stator 3 de verrou 2 (voir flèche 29 sur la figure 6).When mounting the latch 2, it starts by fixing the rotational locking element 15 snap to the latch stator 3 (see arrow 29 in Figure 6).
Puis, dans une deuxième étape, le cache 10 est monté sur le stator 3 de verrou 2 (flèche 30).Then, in a second step, the cover 10 is mounted on the stator 3 of latch 2 (arrow 30).
Ensuite, dans une troisième étape, on fait pivoter le cache 10 sur la collerette 13 (flèche 31 ) jusqu'à ce que la patte d'accrochage 16 coopère avec l'attache 28 verrouillant la rotation du cache 10.Then, in a third step, the cover 10 is pivoted on the flange 13 (arrow 31) until the hooking lug 16 cooperates with the fastener 28 locking the rotation of the cover 10.
L'insertion du verrou 2 dans le corps d'antivol 1 verrouille ensuite définitivement la rotation du cache 10. Le verrou 2 présente ainsi une tenue renforcée face à l'enfoncement ou à l'arrachement du rotor 4, et permet en outre une diminution significative des coûts de production et de montage. The insertion of the latch 2 in the antitheft body 1 then permanently locks the rotation of the cover 10. The latch 2 thus has a reinforced holding against the depression or tearing of the rotor 4, and also allows a reduction significant cost of production and assembly.
