Abstract

The invention relates to an automatic-return cam lock, of the type which comprises a rotor (2) which pivots in a stator (1) by the operation of a key, said stator (1) being fixed to a locking wall, said cam (4) being loosely angularly mounted at the opposite end of the rotor (2) to the key opening, and the rotor (2) returning in relation to the stator (1) by means of a tension spring (3). According to the invention, the lock is characterized in that said cam (4) comprises a locking catch (9) which cooperates with a projection (5) from the stator (1) and a means for rotatably driving the cam (4) from the outside to a position of locking between the catch (9) and the projection (5), the rotor (2) of the lock being in locked position, the angular position of the locked cam (4) being beyond the angular unlocked position in the opening direction of the lock.

Description

Serrure à came pouvant être neutralisée.Cam lock can be neutralized.
L'invention concerne une serrure à came à rappel automa¬ tique pouvant être neutralisée.The invention relates to a cam lock with automatic return which can be neutralized.
De telles serrures sont utilisées par exemple dans des distributeurs de papier, dans les toilettes publiques ou d'entreprises, dans les stations service, etc.; de tels distributeurs comprennent un dispositif d'encliquetage, indépendant de la serrure, pour l'ouverture et la ferme¬ ture du distributeur en vue de son rechargement.Such locks are used for example in paper dispensers, in public or company toilets, in service stations, etc .; such dispensers include a latching device, independent of the lock, for opening and closing the dispenser for recharging.
Certains utilisateurs préfèrent ne pas utiliser une ser¬ rure afin de faciliter l'accès et l'entretien. Cependant, construire un distributeur sans serrure est un problème pour le fabricant qui doit augmenter ses stocks.Il se¬ rait donc utile que l'utilisateur puisse neutraliser la serrure quand il désire laisser libre accès au disposi¬ tif sur lequel elle est montée.Some users prefer not to use a lock to facilitate access and maintenance. However, building a distributor without a lock is a problem for the manufacturer who must increase his stocks. It would therefore be useful for the user to be able to neutralize the lock when he wishes to allow free access to the device on which it is mounted.
L'invention vise en conséquence à atteindre ce but par des moyens simples, efficaces et faciles à utiliser.The invention therefore aims to achieve this goal by simple, effective and easy to use means.
A cet effet, l'invention a pour objet une serrure à came à rappel automatique, du type comprenant un rotor touril- lonnant dans un stator sous l'action d'une clé, ledit stator éτ.ant solidaire d'une paroi à verrouiller, ladite came étant montée à jeu angulaire à l'extrémité du rotor opposée à l'entrée de clé, le rotor étant rappelé par rapport au stator au moyen d'un ressort de torsion, ca¬ ractérisée en ce que ladite came comporte un bec d'encli¬ quetage coopérant avec une saillie du stator et un moyen d'entraînement en rotaτion de la came depuis l'extérieur jusqu'à la position d'encliquetage du bec avec la sail¬ lie, le rotor de la serrure étant en position de ver¬ rouillage, la position angulaire de la came encliquetée étant au-delà de la position angulaire de déverrouillage dans le sens d'ouverture de la serrure.To this end, the subject of the invention is an automatic return cam lock, of the type comprising a revolving rotor in a stator under the action of a key, said stator being integral with a wall to be locked , said cam being mounted at angular play at the end of the rotor opposite the key entry, the rotor being biased relative to the stator by means of a torsion spring, ca¬ characterized in that said cam has a spout locking mechanism cooperating with a protrusion of the stator and a means for driving the cam in rotation from the outside to the position of snap-fitting of the spout with the sail-lie, the rotor of the lock being in position of ver¬ rusting, the angular position of the snapped cam being beyond the angular unlocking position in the direction of opening of the lock.
On amène ainsi facilement la came dans une position dans laquelle elle n'a plus d'action de verrouillage par rota¬ tion du barillet.The cam is thus easily brought into a position in which it no longer has a locking action by rotation of the barrel.
Selon une forme de réalisation de l'invention, le bec d'encliquetage de la came est rigide et la saillie est élastiquement déformable.According to one embodiment of the invention, the cam latching spout is rigid and the projection is elastically deformable.
En variante, le bec d'encliquetage de la came est élasti¬ quement déformable et la saillie est rigide.As a variant, the snap-fit spout of the cam is elastically deformable and the projection is rigid.
L'invention sera bien comprise à la lecture de la des¬ cription suivante faite en se référant au dessin annexé dans lequel:The invention will be clearly understood on reading the following description made with reference to the appended drawing in which:
La figure 1 est une vue schématique en élévation la¬ térale d'une serrure selon un exemple de réalisation de l'invention; la figure 2 est une vue schématique en coupe axiale et élévation de la serrure de la fi¬ gure 1; la figure 3 est une vue de bout de la serru¬ re, côté came, en position de verrouillage; la figu¬ re 4 est analogue à la figure 3, pour la position de déverrouillage, et la figure 5 est analogue aux figu¬ res 3 et 4 , pour la position de neutralisation.Figure 1 is a schematic view in la¬ teral elevation of a lock according to an exemplary embodiment of the invention; Figure 2 is a schematic view in axial section and elevation of the lock of the fi¬ gure 1; Figure 3 is an end view of the lock, cam side, in the locked position; Figure 4 is similar to Figure 3, for the unlocked position, and Figure 5 is similar to Figures 3 and 4, for the neutralization position.
La serrure comprend un stator 1 dans lequel tourillonne un rotor 2 rappelé par un ressort de torsion 3. L'extré¬ mité du rotor 2 opposée à l'entrée de clé porte une cameThe lock comprises a stator 1 in which a rotor 2 journalled by a torsion spring 3. The end of the rotor 2 opposite the key entry carries a cam
4.4.
Dans la position de verrouillage (figure 3), la came 4 est en butée sur un épaulement 5 du stator 1 mais peut pivoter par rapport au rotor 2 grâce à une encoche 6 de 90' d'angle ménageant un jeu angulaire correspondant en- tre la came et l'excentrique 7 du rotor 2.In the locked position (FIG. 3), the cam 4 is in abutment on a shoulder 5 of the stator 1 but can pivot relative to the rotor 2 by virtue of a notch 6 of 90 ′ angle providing a corresponding angular play in- be the cam and the eccentric 7 of the rotor 2.
En position de déverrouillage (figure 4), la came 4 a su¬ bi une rotation d'un angle A dans le sens de la flèche F, sous la poussée de l'excentrique 7.In the unlocked position (FIG. 4), the cam 4 has su¬ bi a rotation of an angle A in the direction of the arrow F, under the thrust of the eccentric 7.
Pour mettre la serrure hors service à partir de la posi¬ tion de verrouillage, il suffit d'introduire un outil à travers un évidement de la paroi à verrouiller (non re¬ présentée) pour qu'il vienne en appui contre la came et à faire ainsi tourner la came 4 d'un angle de 90*. Un bec 9 de la came 4 vient s'encliqueter sur la saillie 5 du sta¬ tor 1. Le bec 9 ou la saillie 5 peut à cet effet être élastiquement déformable. To put the lock out of service from the locking position, it suffices to introduce a tool through a recess in the wall to be locked (not shown) so that it comes to bear against the cam and thus rotate the cam 4 by an angle of 90 * . A spout 9 of the cam 4 snaps onto the projection 5 of the sta¬ tor 1. The spout 9 or the projection 5 can for this purpose be elastically deformable.
