Description

La présente invention concerne un verrou à clé plate à paillettes résistant aux tentatives d'effraction du type de celui, qui est, par exemple, destiné à équiper les véhicules automobiles. The present invention relates to a flat key lock with glitter resistant to burglary attempts of the type, which is, for example, intended to equip motor vehicles.

Un verrou de type classique comprend simplement un stator à l'intérieur duquel est disposé un rotor rendu solidaire du stator par des moyens rétractables tels que des paillettes. Le rotor comporte à son extrémité un ergot destiné à coopérer avec un logement complémentaire ménagé dans un dispositif entraîneur du mécanisme d'ouverture de la serrure. Cette coopération, entre rotor et dispositif entraîneur, est permanente. A conventional type lock simply comprises a stator inside which is arranged a rotor made integral with the stator by retractable means such as flakes. The rotor has at its end a lug intended to cooperate with a complementary housing formed in a device driving the opening mechanism of the lock. This cooperation, between rotor and driving device, is permanent.

De tels verrous sont insuffisamment résistants aux tentatives d'effraction qui sont habituellement de deux sortes. Une première méthode consiste à faire tourner le rotor à force en lui appliquant un couple suffisant pour rompre les paillettes et libérer le rotor, ou en entraînant l'ensemble du verrou en rotation par rapport à la porte sur laquelle il est monté, cette rotation à force s'opérant au moyen d'un outil introduit dans l'entrée du canal de clé. Une seconde méthode consiste à crocheter le verrou en appliquant au rotor un léger couple pour accrocher les paillettes une par une successivement. Such locks are insufficiently resistant to burglary attempts which are usually of two kinds. A first method consists in forcing the rotor to rotate by applying sufficient torque to it to break the flakes and release the rotor, or by driving the entire lock in rotation relative to the door on which it is mounted, this rotation at force operating by means of a tool inserted into the entry of the key channel. A second method consists in hooking the lock by applying a slight torque to the rotor to hang the sequins one by one successively.

On a proposé, pour interdire de telles tentatives, des verrous à stator débrayable permettant un désaccouplement du stator par rapport au corps dans lequel il est monté. It has been proposed, to prohibit such attempts, disengageable stator locks allowing uncoupling of the stator relative to the body in which it is mounted.

Dans de tels verrous, si la bonne clé n'est pas introduite et si l'on force sur le rotor, le stator tourne librement et n'actionne pas le dispositif entraîneur. Cependant, de tels verrous nécessitent des pièces supplémentaires et sont d'un assemblage particulièrement délicat, ce qui a pour conséquence une augmentation de coût compatible avec les nécessités économiques d'une fabrication en grande série comme c'est le cas, en particulier, dans le domaine automobile. In such locks, if the correct key is not inserted and if the rotor is forced, the stator turns freely and does not actuate the driving device. However, such locks require additional parts and are particularly delicate to assemble, which results in an increase in cost compatible with the economic necessities of mass production as is the case, in particular, in the automotive field.

La présente invention résoud ces problèmes et propose à cet effet un verrou à clé plate à paillettes comportant un stator présentant des rainures permettant le passage des paillettes et un alésage à l'intérieur duquel est monté tourillonnant un rotor antérieur équipé des paillettes, ledit rotor antérieur étant libre en rotation et bloqué en translation par les paillettes avant introduction de la clé, caractérisé en ce que le rotor antérieur peut coulisser dans l'alésage sous l'action de la pression de la pointe de clé contre un rotor postérieur adjacent au rotor antérieur et coopérant avec une came de commande de manière telle à ce que le rotor postérieur soit désolidarisé du rotor antérieur avant introduction de la clé et à en être solidaire après introduction de la clé et coulissement du rotor antérieur sous la pression de la pointe de clé. The present invention solves these problems and proposes for this purpose a flanged key lock comprising a stator having grooves allowing the passage of the flakes and a bore inside which is journalled a front rotor equipped with the flakes, said front rotor being free in rotation and locked in translation by the flakes before introduction of the key, characterized in that the front rotor can slide in the bore under the action of the pressure of the key tip against a rear rotor adjacent to the front rotor and cooperating with a control cam in such a way that the rear rotor is detached from the front rotor before introduction of the key and to be joined thereto after introduction of the key and sliding of the front rotor under the pressure of the key tip.

De cette manière, toute tentative d'effraction par rotation à force, qui ne provoque pas le coulissement du rotor antérieur ne permet pas la rotation du rotor postérieur et donc l'entraînement du mécanisme de la serrure qui est associé à la serrure. In this way, any attempt to break in by force rotation, which does not cause the sliding of the front rotor, does not allow the rotation of the rear rotor and therefore the drive of the lock mechanism which is associated with the lock.

L'invention sera mieux comprise avec la description qui va suivre en regard des dessins annexés dans lesquels
- la figure 1 est une vue schématique en coupe longitudinale d'un verrou selon l'invention ;
- la figure 2 est analogue à la figure 1, une fausse clé ayant été introduite
- la figure 3 est analogue aux figures 1 et 2, une bonne clé ayant été complètement enfoncée dans le rotor.
The invention will be better understood with the description which follows with reference to the appended drawings in which
- Figure 1 is a schematic view in longitudinal section of a lock according to the invention;
- Figure 2 is similar to Figure 1, a false key having been introduced
- Figure 3 is similar to Figures 1 and 2, a good key having been fully inserted into the rotor.

Le verrou à paillettes représenté aux figures 1 et 3 comprend un stator 11 présentant un alésage 12 et des rainures 13, au nombre de six dans l'exemple représenté permettant le passage des paillettes 14.  The glitter lock shown in FIGS. 1 and 3 comprises a stator 11 having a bore 12 and grooves 13, six in number in the example shown allowing the glitter 14 to pass.

Suivant un aspect de l'invention, l'ensemble rotorique est constitué de deux parties, un rotor antérieur 15 et un rotor postérieur 16 qui sont montés tourillonnants dans l'alésage 12 et qui sont adjacents par une face d'extrémité orthogonale. According to one aspect of the invention, the rotor assembly is made up of two parts, a front rotor 15 and a rear rotor 16 which are mounted journalled in the bore 12 and which are adjacent by an orthogonal end face.

Le rotor antérieur 15 est maintenu axialement par un cache de serrure 17 solidaire du stator 11. Ce rotor antérieur 15 présente un canal de clé 18 et des logements pour les paillettes 14. The front rotor 15 is held axially by a lock cover 17 secured to the stator 11. This front rotor 15 has a key channel 18 and housings for the flakes 14.

Le rotor antérieur 15 est prolongé par une portion cylindrique 19 et un nez d'accouplement 20. The front rotor 15 is extended by a cylindrical portion 19 and a coupling nose 20.

Le rotor postérieur 16 porte la came de commande 21 du mécanisme de la serrure auquel est associé le verrou et présente un logement 22 de forme complémentaire au nez d'accouplement 20 du rotor antérieur 15. The rear rotor 16 carries the control cam 21 of the lock mechanism with which the lock is associated and has a housing 22 of complementary shape to the coupling nose 20 of the front rotor 15.

Un ressort 23, présente une branche 24 verrouillant le rotor postérieur 16 sur le stator 11. A spring 23 has a branch 24 locking the rear rotor 16 on the stator 11.

On constate sur la figure 1 qu'aucune clé n'étant engagée, les paillettes 14 sont engagées dans les rainures 13 du stator 11, verrouillant ainsi le rotor antérieur 15 en translation mais le laissant libre en rotation. It can be seen in FIG. 1 that no key being engaged, the flakes 14 are engaged in the grooves 13 of the stator 11, thus locking the front rotor 15 in translation but leaving it free to rotate.

La figure 2 montre que l'introduction d'une fausse clé 25 ou d'un outil dans le canal de clé 18 permet au rotor antérieur 15 d'être toujours libre en rotation mais le bloque en translation par les paillettes 14 empêchant ainsi sa coopération avec le rotor postérieur 16. FIG. 2 shows that the introduction of a false key 25 or of a tool into the key channel 18 allows the front rotor 15 to be always free to rotate but blocks it in translation by the flakes 14 thus preventing its cooperation with the rear rotor 16.

Sur la figure 3, l'introduction d'une bonne clé 25 dans le canal de clé 18 fait que les paillettes 14 sont toutes à l'intérieur de l'alésage 12 libérant ainsi le rotor antérieur 15 en rotation et en translation. In FIG. 3, the introduction of a good key 25 into the key channel 18 means that the flakes 14 are all inside the bore 12 thus releasing the front rotor 15 in rotation and in translation.

Lorsque la clé 25 est poussée à fond, elle entraîne le rotor antérieur 15 en translation dont le nez d'accouplement 20 vient s'encastrer dans le logement 22 du rotor postérieur 16 rendant ainsi solidaires en rotation les rotors antérieur 15 et postérieur 16. When the key 25 is fully pushed, it drives the front rotor 15 in translation, the coupling nose 20 of which is embedded in the housing 22 of the rear rotor 16, thus making the front 15 and rear 16 rotors integral in rotation.

Simultanément, la translation du rotor antérieur 15 entraîne une compression du ressort 23 qui permet à sa branche 24 de sortir du stator 11 rendant ainsi le rotor postérieur 16 libre en rotation. Simultaneously, the translation of the front rotor 15 causes compression of the spring 23 which allows its branch 24 to exit the stator 11 thus making the rear rotor 16 free to rotate.

Une rotation de la clé 25 permet alors l'actionnement de la came de commande 21 du mécanisme de la serrure. A rotation of the key 25 then allows the actuation of the control cam 21 of the lock mechanism.

Bien entendu, la présente invention n'est nullement limitée à la forme de réalisation décrite cidessus et représentée sur les dessins, et l'homme de métier pourra y apporter toute variante ou modification conforme à son esprit. Of course, the present invention is in no way limited to the embodiment described above and shown in the drawings, and the person skilled in the art can make any variant or modification in accordance with his spirit.

En particulier, le nombre de paillettes 14 pourra être quelconque ainsi que les formes complémentaires du nez d'accouplement 20 et du logement 22 qui lui est associé sans pour cela sortir du cadre de l'invention.  In particular, the number of flakes 14 may be arbitrary as well as the complementary shapes of the coupling nose 20 and of the housing 22 associated therewith without thereby departing from the scope of the invention.
