Abstract
Description
VERROU A CLE PLATE A PISTONS ANTI-EFFRACTION.FLAT KEY LOCK WITH ANTI-INFRINGEMENT PISTONS.
La présente addition concerne un perfectionnement au verrou selon le brevet principal, assurant une sûreté plus élevée. The present addition relates to an improvement to the lock according to the main patent, ensuring higher security.
Le verrou selon la présente addition est caractérisé par le fait que les contrepistons coopérant avec les pistons du logement sont montés avec leurs ressorts de rappel dans le rotor. De cette manière, le rotor tourne librement dans le stator avec une fausse clé, sans que l'entraîneur puisse être actionné. The lock according to the present addition is characterized in that the counter pistons cooperating with the pistons of the housing are mounted with their return springs in the rotor. In this way, the rotor turns freely in the stator with a false key, without the driver being able to be actuated.
De préférence, le rotor est muni d'un dispositif d'indexation par rapport au stator. Ce dispositif d'indexation peut être constitué, de manière connue en soi, par une bille rappelée par ressort. Preferably, the rotor is provided with an indexing device relative to the stator. This indexing device can be constituted, in a manner known per se, by a ball returned by spring.
L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel:
- la figure 1 est une vue schématique en coupe longitudinale d'un verrou selon un exemple de réalisation de l'invention, clé enlevée;
- la figure 2 est analogue à la figure 1, la clé corres- pondant à la combinaison du verrou ayant été introduite en position de déverrouillage, et
- la figure 3 est analogue aux figures 1 et 2, la cle ayant été complètement enfoncée dans le rotor.The invention will be clearly understood on reading the following description made with reference to the appended drawing in which:
- Figure 1 is a schematic view in longitudinal section of a lock according to an exemplary embodiment of the invention, key removed;
FIG. 2 is similar to FIG. 1, the key corresponding to the combination of the lock having been introduced in the unlocked position, and
- Figure 3 is similar to Figures 1 and 2, the key having been fully inserted into the rotor.
Le verrou représenté aux figures 1, 2 et 3 comprend un stator 109 comportant un alésage 110. The lock shown in FIGS. 1, 2 and 3 comprises a stator 109 comprising a bore 110.
Un rotor antérieur 101 et un entraîneur 107 sont montés tourillonnants dans l'alésage 110, adjacents par une face d' extrémité orthogonale. A front rotor 101 and a driver 107 are mounted journalled in the bore 110, adjacent by an orthogonal end face.
Le rotor antérieur 101 est maintenu axialement par un cache et l'entraîneur 107 porte la came de commande 112 du mécanisme de la serrure auquel est associé le verrou. Le rotor antérieur 101 possède une clavette 102 (ou logement) dans laquelle sont logés les pistons inférieurs 105 qui viennent reposer sur un bossage 116 du canal de clé 113. Le rotor 101 comporte également des alésages 114, recevant les contrepistons 103 et leurs ressorts 104. Une butée 115 sert de point d'application au bout de la clé 106. La clavette 102 est pourvue a sa face arrière d'un nez d'accouplement. The front rotor 101 is held axially by a cover and the driver 107 carries the control cam 112 of the lock mechanism with which the lock is associated. The front rotor 101 has a key 102 (or housing) in which are housed the lower pistons 105 which come to rest on a boss 116 of the key channel 113. The rotor 101 also has bores 114, receiving the counter pistons 103 and their springs 104 A stop 115 serves as an application point at the end of the key 106. The key 102 is provided at its rear face with a coupling nose.
La clé étant retirée, les contre-pistons 103 viennent s'engager dans la clavette 102 et verrouillent celle-ci. With the key removed, the counter-pistons 103 engage the key 102 and lock the latter.
Au contraire (figure 2), lorsque la clé est engagée dans le canal de clé 113, la clavette 102 est libérée en translation les pistons inférieurs 105 étant alignés. On the contrary (Figure 2), when the key is engaged in the key channel 113, the key 102 is released in translation with the lower pistons 105 being aligned.
En figure 3, la clé est poussée a fond entraînant la clavette 102. Le nez d'accouplement 115 de cette clavette vient s' encastrer dans l'évidement 117 rendant solidaires le rotor 101 et l'entraineur 107. In FIG. 3, the key is fully pushed driving the key 102. The coupling nose 115 of this key comes to be embedded in the recess 117 making the rotor 101 and the driver 107 integral.
La poussée de la clé agit sur une butée dimensionnée de sorte que toute poussée anormale entraîne sa rupture. The thrust of the key acts on a stop dimensioned so that any abnormal thrust causes it to break.
La rotation du rotor 101 n'est pas liée au dispositif de sécurité que forme l'ensemble des pistons 104 et 105. The rotation of the rotor 101 is not linked to the safety device formed by all of the pistons 104 and 105.
Le fonctionnement du verrou est assuré par l'accouplement des deux pièces rotor 101 et entraîneur 107 qui est réalisé par la clavette 102 dont le coulissement est verrouillé par le dispositif de sécurité formé par les pistons 104 et 105. Le positionnement en rotation du rotor se fait par billage 108. The operation of the lock is ensured by the coupling of the two pieces of rotor 101 and driver 107 which is produced by the key 102, the sliding of which is locked by the safety device formed by the pistons 104 and 105. The rotational positioning of the rotor is made by billage 108.
