Description

Serrure à came batteuse à rattrapage de ieu.Cam cam threshing lock.

L'invention concerne une serrure à came batteuse du type comprenant un rotor tourillonnant dans un stator sous l'action d'une clé codée, l'extrémité dudit rotor opposée à l'entrée de clé portant une came d'ouverture-fermeture d'un battant.The invention relates to a cam-type lock of the type comprising a rotor swiveling in a stator under the action of a coded key, the end of said rotor opposite the key entry carrying an opening-closing cam of a fighter.

Les serrures de ce type sont en particulier utilisées, sous la forme simple décrite ci-dessus, pour verrouiller directement une porte, par exemple de boite à lettres ou d'un coffret quelconque, ainsi que sur des porte-objets (par exemple porteskis, porte-vélos, etc.) montés sur un véhicule automobile et/ou pour verrouiller lesdits objets sur un tel porte-objets.Locks of this type are in particular used, in the simple form described above, to directly lock a door, for example of a letterbox or any other box, as well as on object holders (for example portekis, bicycle carriers, etc.) mounted on a motor vehicle and / or for locking said objects on such an object carrier.

Dans le cas par exemple d'un coffret, la serrure est montée sur la porte et la came batteuse vient se verrouiller derrière un retour du boîtier de coffret. La serrure peut également être montée sur la partie fixe, la came batteuse coopérant alors avec une languette de verrouillage solidaire à une de ses extrémités de la porte et montée parallèle à cette porte.In the case for example of a cabinet, the lock is mounted on the door and the cam comes to lock behind a return of the cabinet housing. The lock can also be mounted on the fixed part, the threshing cam then cooperating with a locking tab secured to one of its ends of the door and mounted parallel to this door.

Ce type de verrouillage présente l'inconvénient que les tolérances de fabrication du coffret ou du porte-objet, qui impliquent des variations de cotes, et/ou les jeux produits en utilisation, par exemple par les vibrations du véhicule, ne sont pas absorbées par la came, rendue solidaire du rotor en général par un écrou ou par sertissage. I1 en résulte donc des nuisances telles qu'une mauvaise fermeture de porte ou l'apparition de bruits pour les dispositifs à usage automobile.This type of locking has the disadvantage that the manufacturing tolerances of the box or the object holder, which involve variations in dimensions, and / or the clearances produced in use, for example by vehicle vibrations, are not absorbed by the cam, made integral with the rotor in general by a nut or by crimping. I1 therefore results in nuisances such as poor door closing or the appearance of noise for devices for automotive use.

La présente invention a en conséquence pour but de supprimer ces inconvénients en permettant d'absorber les jeux de construction et/ou d'usage du dispositif à fermer.The object of the present invention is therefore to eliminate these drawbacks by making it possible to absorb the construction and / or use clearances of the device to be closed.

A cet effet, la serrure selon l'invention est caractérisée en ce que la came batteuse est fixée de manière élastique au rotor et/ou possède une élasticité propre.To this end, the lock according to the invention is characterized in that the threshing cam is fixed elastically to the rotor and / or has its own elasticity.

L'élasticité de la came batteuse par rapport au rotor permet d'absorber les jeux en permettant une fermeture toujours parfaite et l'absence de vibrations génératrices de bruit.The elasticity of the threshing cam with respect to the rotor makes it possible to absorb the clearances by allowing always perfect closing and the absence of vibrations generating noise.

De préférence, la came batteuse est fixée au rotor par un clip élastiquement déformable monté dans une gorge de ladite extrémité du rotor et en appui sur ladite came batteuse. Le montage de la came batteuse est en outre fortement simplifié par rapport à une fixation par écrou nécessitant la pose de rondelles et le serrage de l'écrou.Preferably, the threshing cam is fixed to the rotor by an elastically deformable clip mounted in a groove of said end of the rotor and in abutment on said threshing cam. The mounting of the cam is also greatly simplified compared to a fixing by nut requiring the installation of washers and the tightening of the nut.

I1 est également possible de prévoir que la came batteuse est élastiquement déformable, par exemple constituée par un ressort-lame précambré.  It is also possible to provide that the threshing cam is elastically deformable, for example constituted by a precambered leaf spring.

L'invention sera bien comprise à la lecture de la description suivante faite en référence au dessin annexé dans lequel
La figure 1 est une vue en élévation latérale d'une
serrure selon un exemple de réalisation de l'invention,
en position de verrouillage sans absorption de jeu,
la figure 2 est analogue à la figure 1, pour une
position de verrouillage avec absorption d'un jeu
maximal, et
la figure 3 est une vue en coupe selon la ligne III-III
de la figure 1.The invention will be clearly understood on reading the following description made with reference to the accompanying drawing in which
Figure 1 is a side elevational view of a
lock according to an exemplary embodiment of the invention,
in the locked position without backlash absorption,
Figure 2 is similar to Figure 1, for a
locking position with clearance absorption
maximum, and
Figure 3 is a sectional view along line III-III
of figure 1.

La serrure comprend un stator 1 fixé par un écrou 2 sur une ouverture d'une paroi mobile 3 telle qu'une porte.The lock comprises a stator 1 fixed by a nut 2 on an opening of a movable wall 3 such as a door.

Un rotor 4 tourillonne dans le stator 1 sous la commande d'une clé (non représentée) introduite par l'extrémité externe 5 du rotor 4. L'extrémité interne du rotor 4 comporte une gorge 6 à section transversale non circulaire, par exemple de forme approximativement rectangulaire, la portion saillante 7 du rotor 4 ayant alors une forme en section transversale également rectangulaire de même largeur.A rotor 4 pivots in the stator 1 under the control of a key (not shown) introduced by the outer end 5 of the rotor 4. The inner end of the rotor 4 has a groove 6 of non-circular cross section, for example of approximately rectangular in shape, the projecting portion 7 of the rotor 4 then having a cross-sectional shape also rectangular of the same width.

Une came batteuse 8 comporte une ouverture traversante 9, de dimensions légèrement supérieures à celles de la section transversale de la portion saillante 7 du rotor 4, qui est logée sur la gorge 6. La came 8 est fixée au rotor 4 par un clip 10 à deux bras élastiquement déformables 11, précambrés, le clip 10 formant une fourchette qui est logée sur la gorge 6 entre la came 8 et le bord de la portion saillante 7 du rotor 4. L'extrémité libre de la came 8 coopère, en position de verrouillage avec une rampe 12 du dormant 13.A threshing cam 8 has a through opening 9, of dimensions slightly greater than those of the cross section of the projecting portion 7 of the rotor 4, which is housed on the groove 6. The cam 8 is fixed to the rotor 4 by a clip 10 to two elastically deformable arms 11, precambered, the clip 10 forming a fork which is housed on the groove 6 between the cam 8 and the edge of the projecting portion 7 of the rotor 4. The free end of the cam 8 cooperates, in the position of locking with a ramp 12 of the frame 13.

En l'absence de jeu (figure 1), l'extrémité libre de la came 8 s'appuie au sommet de la rampe 12 sans déformation de la fourchette 10, la distance A entre le dormant 13 et la came 8 étant la longueur de construction.In the absence of play (FIG. 1), the free end of the cam 8 rests on the top of the ramp 12 without deformation of the fork 10, the distance A between the frame 13 and the cam 8 being the length of construction.

Par contre, si cette distance A a augmenté, du fait de jeux, jusqu'à une valeur maximale A1 (figure 2), la came 8 s'incline sur la gorge 6 en déformant élastiquement les branches 11 de la fourchette 10 et en venant buter contre le corps de la fourchette 10 appuyé sur le bord interne de la partie saillante 7 du rotor 4.On the other hand, if this distance A has increased, due to play, to a maximum value A1 (FIG. 2), the cam 8 inclines on the groove 6 by elastically deforming the branches 11 of the fork 10 and coming abut against the body of the fork 10 supported on the internal edge of the projecting part 7 of the rotor 4.

Il est ainsi possible d'absorber un jeu allant jusqu a une valeur maximale A1 - A en garantissant une fermeture complète du battant 3 qui est ainsi appliqué contre le dormant 13 par la pression élastique des bras 11 du clip ou fourchette 10.It is thus possible to absorb a play going up to a maximum value A1 - A while guaranteeing a complete closing of the leaf 3 which is thus applied against the frame 13 by the elastic pressure of the arms 11 of the clip or fork 10.

Bien entendu, dans le cas d'une serrure montée sur le dormant 13, la fourchette 10 est montée entre la came 8 et le bord opposé de la gorge 6, la came 8 pouvant alors pivoter dans le sens inverse des aiguilles d'une montre (sur le dessin).Of course, in the case of a lock mounted on the frame 13, the fork 10 is mounted between the cam 8 and the opposite edge of the groove 6, the cam 8 then being able to pivot anticlockwise (on the drawing).

Comme on l'a indiqué, la came 8 peut être elle-même élastiquement déformable, en étant montée rigidement sur le rotor ou par l'intermédiaire d'un organe élastique tel que la fourchette 10. La came 8 peut alors être constituée d'un ressort-lame cambré. As indicated, the cam 8 can itself be elastically deformable, by being rigidly mounted on the rotor or by means of an elastic member such as the fork 10. The cam 8 can then be made of a curved leaf spring.
