Abstract

The invention relates to a lock according to Claim 1 of the main patent. The lock according to the invention is characterised by the fact that it comprises a lever 18' articulated about a pin 19' integral with the keyplate and comprising a catch 4' interacting with a notch 17' of the stator 2', the said lever 18' being returned by a spring 5' towards the said stator 2'. Application to lock work.

Description

Serrure à bloc de sQreté rapporté, agencée pour empêcher son ouverture frauduleuse.Add-on security lock, designed to prevent fraudulent opening.

La présente addition concerne des perfectionnements à la revendication 1 du brevet principal.The present addition relates to improvements to claim 1 of the main patent.

Elle vise en particulier à simplifier la réalisation de la serrure du brevet principal, à en diminuer l'encombrement axial et à renforcer la solidarisation entre le rotor et le stator en cas de manoeuvre frauduleuse.It aims in particular to simplify the production of the lock of the main patent, to reduce its axial size and to strengthen the connection between the rotor and the stator in the event of fraudulent operation.

A cet effet, l'invention a pour objet une serrure selon la revendication 1 du brevet principal, caractérisée par le fait qu'elle comprend un levier articulé autour d'un axe solidaire du foncet et comportant un bec coopérant avec une encoche du stator, ledit levier étant rappelé par ressort vers ledit stator.To this end, the subject of the invention is a lock according to claim 1 of the main patent, characterized in that it comprises a lever articulated around an axis integral with the bolt and comprising a spout cooperating with a notch in the stator, said lever being returned by spring towards said stator.

Selon une forme de réalisation de l'invention, un verrou coulisse radialement dans un alvéole du stator, ledit verrou comportant une tête élargie biseautée coopérant avec un trou du capot, l'extrémité opposée dudit verrou pouvant coopérer avec un trou du rotor lorsque la tête du verrou est soulevée hors du trou du capot contre l'action d'un ressort de rappel.According to one embodiment of the invention, a lock slides radially in a cell of the stator, said lock comprising an enlarged beveled head cooperating with a hole in the cover, the opposite end of said lock being able to cooperate with a hole in the rotor when the head of the latch is lifted out of the cover hole against the action of a return spring.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au desssin annexe dans lequel la figure 1 représente une vue du dispositif en'élévation et coupe partielle, la figure 2 représente les positions relatives du rotor, du stator et du pêne en fonctionnement normal, la figure 3 represente les positions relatives des mêmes éléments en cas de tentative frauduleuse, la figure 4 est une coupe transversale suivant le plan AA du rotor et du stator en fonctionnement normal, et la figure 5 est une coupe transversale suivant le plan AA des mêmes organes en cas de manoeuvre frauduleuse.The invention will be clearly understood on reading the following description made with reference to the annexed drawing in which FIG. 1 represents a view of the device in elevation and partial section, FIG. 2 represents the relative positions of the rotor, of the stator and of the bolt in normal operation, Figure 3 shows the relative positions of the same elements in the event of fraudulent attempt, Figure 4 is a cross section along the plane AA of the rotor and the stator in normal operation, and Figure 5 is a cross section according to the AA plan of the same bodies in the event of fraudulent manipulation.

Les mêmes références qu'au brevet principal, affectées d'un indice, sont utilisées pour les pièces- similaires de la présente addition.The same references as in the main patent, assigned an index, are used for similar parts of this addition.

Le stator 2' est positionné dans le capot 3' solidaire du foncet 6' grâce à un cran 17' dans lequel est engagé le bec 4' d'un levier 18' articulé sur un axe 19' solidaire du foncet et rappelé par un ressort 5'. Ce système se substitue à l'ensemble bille 4, alvéole 4', ressort 5 et obturateur 15 de la figure 1 du brevet principal qui a l'inconvénient de faire une saillie importante en dehors du capot 3. Par ailleurs la solidarisation du rotor 1' et du stator 2' est obtenue au moyen d'un verrou 20' coulissant dans un alvéole 21' pratiqué radialement dans le stator 2'. Ce verrou porte une tête large 22' dont l'extrémité biseautée s'engage partiellement, en position normale, dans un trou 23' pratiqué dans le capot 3'.The stator 2 'is positioned in the cover 3' secured to the shack 6 'by means of a notch 17' in which is engaged the spout 4 'of a lever 18' articulated on an axis 19 'secured to the shack and returned by a spring 5 '. This system replaces the ball 4, cell 4 ′, spring 5 and shutter 15 assembly of FIG. 1 of the main patent which has the drawback of making a significant projection outside the cover 3. Furthermore, the attachment of the rotor 1 'and the stator 2' is obtained by means of a lock 20 'sliding in a cavity 21' formed radially in the stator 2 '. This lock carries a wide head 22 'whose beveled end partially engages, in the normal position, in a hole 23' made in the cover 3 '.

Dans ces conditions, l'extrémité du verrou 20' opposée à la tête 22' est en retrait par rapport à un trou 24' pratiqué dans le rotor 1', par l'action du ressort de compression 25', de sorte que le rotor 1' peut tourner librement sous l'action de la clé d'ouverture.Under these conditions, the end of the bolt 20 'opposite the head 22' is set back with respect to a hole 24 'made in the rotor 1', by the action of the compression spring 25 ', so that the rotor 1 'can rotate freely under the action of the opening key.

En cas de manoeuvre frauduleuse, le stator 2' tourne en même temps que le rotor 1' en raison des organes de liaison, pistons 12' et goupilles 13', en position de verrouillage.In the event of fraudulent operation, the stator 2 'rotates at the same time as the rotor 1' due to the connecting members, pistons 12 'and pins 13', in the locked position.

Le verrou 22' est repoussé en frottant sur la paroi interne du capot 3', contre l'action du ressort de compression 25', ce qui fait pénétrer son extrémite 20' dans l'alvéole 24' du rotor. La liaison entre le rotor 1' et le stator 2' est ainsi renforcée. The latch 22 'is pushed back by rubbing against the internal wall of the cover 3', against the action of the compression spring 25 ', which causes its end 20' to penetrate into the cavity 24 'of the rotor. The connection between the rotor 1 'and the stator 2' is thus reinforced.
