Description
VERROU A CLE PLATE A PISTONS ANTI-EFFRACTION. FLAT KEY LOCK WITH ANTI-INFRINGEMENT PISTONS.
L'invention concerne un verrou à clé plate à pistons résistant aux tentatives d'effraction. The invention relates to a flat key piston lock resistant to burglary attempts.
Les tentatives d'effraction de verrous sont habituellement de deux sortes. La première méthode consiste à tenter de faire tourner le rotor à force en lui appliquant un couple suffisant pour rompre les pistons et libérer le rotor. Cette rotation à force est opérée au moyen d'un outil introduit dans l'entrée du canal de clé. Une autre méthode consiste à crocheter le verrou en appliquant au rotor un léger couple pour accrocher les pistons ou les paillettes un par un successivement. Attempts to break in locks are usually of two kinds. The first method consists in trying to turn the rotor by force by applying sufficient torque to it to break the pistons and release the rotor. This force rotation is effected by means of a tool inserted into the entry of the key channel. Another method is to hook the bolt by applying a slight torque to the rotor to hook the pistons or the flakes one by one successively.
On a proposé, pour interdire de telles tentatives, de réaliser le rotor en deux parties bout à bout, de sorte que les tentatives de crochetage produisent une rotation de la partie antérieure du rotor sans la partie postérieure. Cependant, un tel verrou résiste mal aux tentatives de rotation du rotor à force au moyen d'un outil très résistant complètement enfoncé dans le canal et qui solidarise ainsi les deux parties du rotor. It has been proposed, to prohibit such attempts, to make the rotor in two parts end to end, so that the picking attempts produce a rotation of the front part of the rotor without the rear part. However, such a lock does not withstand attempts to forcely rotate the rotor by means of a very resistant tool completely inserted into the channel and which thus secures the two parts of the rotor.
La présente invention vise à interdire les tentatives d'effraction qui viennent d'être décrites, au moyen d'un nouveau verrou de construction simple et économique. The present invention aims to prohibit burglary attempts which have just been described, by means of a new lock of simple and economical construction.
A cet effet, le verrou selon l'invention est caractérisé par le fait que les pistons du rotor sont montés dans un logement coulissant par rapport au rotor sous l'action de la pression de la pointe de clé contre une butée dudit logement, ledit logement coopérant avec un entraîneur de manière à en être désolidarise avant introduction de la clé et à en être solidaire après introduction de la clé et coulissement sous la pression de la pointe de clé. To this end, the lock according to the invention is characterized in that the pistons of the rotor are mounted in a housing sliding with respect to the rotor under the action of the pressure of the key tip against a stop of said housing, said housing cooperating with a trainer so as to be detached from it before introduction of the key and to be integral thereto after introduction of the key and sliding under the pressure of the key tip.
Toute tentative d'effraction par rotation à force, qui ne provoque pas le coulissement du logement de pistons rotoriques, ne permet pas la rotation de l'entraîneur, donc le fonctionnement du verrou. Any attempt to break in by force rotation, which does not cause the rotor piston housing to slide, does not allow the rotation of the driver, therefore the operation of the lock.
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 ayant été introduite en position de libération du rotor, et
- la figure 3 est analogue aux figures 1 et 2, la clé 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:
FIG. 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 having been introduced in the rotor release position, and
- Figure 3 is similar to Figures 1 and 2, the key having been fully inserted into the rotor.
Le verrou à pistons représenté aux figures 1, 2 et 3 comprend un stator 1 comportant un alésage 2 et des logements 3 recevant les pistons statoriques 4 et les ressorts 5. The piston lock shown in FIGS. 1, 2 and 3 comprises a stator 1 comprising a bore 2 and housings 3 receiving the stator pistons 4 and the springs 5.
Un rotor antérieur 6 et un rotor postérieur ou entraîneur 7 sont montés tourillonnants dans l'alésage 2 adjacents par une face d'extrémité orthogonale. An anterior rotor 6 and a posterior or driving rotor 7 are mounted journalling in the adjacent bore 2 by an orthogonal end face.
Le rotor antérieur 6 est maintenu axialement par une clavette 8 et le rotor postérieur 7 porte la came de commande 9 du mécanisme de la serrure auquel est associé le verrou. Le rotor antérieur 6 possède un logement 13 pour les pistons rotoriques coulissant dans le rotor antérieur 6. Une butée 16 sur ce logement 13 sert de point d'application au bout de la clé 11. Le logement 13 est pourvu à sa face arrière d'un nez d'accouplement 14. La clé 11 étant retirée, les pistons supérieurs 4 viennent s'engager dans le logement de pistons 13 et verrouillent le rotor 6 en rotation et le logement de pistons 13 en translation. The front rotor 6 is held axially by a key 8 and the rear rotor 7 carries the control cam 9 of the lock mechanism with which the lock is associated. The front rotor 6 has a housing 13 for the rotor pistons sliding in the front rotor 6. A stop 16 on this housing 13 serves as an application point at the end of the key 11. The housing 13 is provided on its rear face with a coupling nose 14. With the key 11 removed, the upper pistons 4 engage in the piston housing 13 and lock the rotor 6 in rotation and the piston housing 13 in translation.
Au contraire (figure 2) lorsque la clé 11 est engagée dans le canal de clé 10, le rotor est libéré en rotation et le logement de pistons 13 peut opérer sa translation, les pistons inférieurs 12 étant alignés. On the contrary (Figure 2) when the key 11 is engaged in the key channel 10, the rotor is released in rotation and the piston housing 13 can operate its translation, the lower pistons 12 being aligned.
En figure 3, la clé est poussée à fond entraînant le logement de pistons 13. Le nez d'accouplement 14 du logement de pistons 13 vient s'encastrer dans l'évidement 15 rendant solidaires le rotor 6 et l'entraîneur 7. La rotation de la clé entraîne donc la rotation du rotor 6 et de l'entraîneur 7 et commande le mécanisme d'ouverture de la serrure. La poussée de la clé agit sur une butée dimensionnée pour résister à toute action normale mais devant se rompre sous toute action de force. In FIG. 3, the key is pushed to the bottom, driving the piston housing 13. The coupling nose 14 of the piston housing 13 is fitted into the recess 15 making the rotor 6 and the driver 7 integral. The rotation of the key therefore drives the rotation of the rotor 6 and of the driver 7 and controls the mechanism for opening the lock. The push of the key acts on a stop dimensioned to resist any normal action but having to break under any force action.
