Abstract

A lock with a bolt (1) or slider operated by a rotary drive member (2) actuated by a key and rotary security element (4), such as a barrel or cylinder, has the drive member located with an angular clearance in a lengthwise slot (5) in a freely-rotating ring (6). The bolt or slider has a rectangular lengthwise cut-out (8) forming two end shoulders (9,10) with a central tooth (13). The drive member is located eccentrically relative to the ring and its pivot axis (3) is offset further from the slider than the axis of rotation of the ring. The length of the tooth is such that the trajectory of the free end of the drive member does not intersect the parallel to the slider's direction of travel at a tangent to the tooth's free end.

Description

La présente invention concerne une serrure à organe de commande de verrouillage, tel qu'un pêne ou un coulisseau de commande d'au moins un pêne, ledit organe de commande de verrouillage étant monté coulissant sous l'action d'un entraíneur rotatif actionné par une clé coopérant avec un organe de sécurité tel qu'un barillet, un cylindre profilé ou un canon, ledit entraíneur rotatif étant logé avec jeu angulaire dans une fente radiale d'une bague montée libre en rotation, ledit organe de commande de verrouillage comportant une découpure longitudinale sensiblement rectangulaire formant deux épaulements d'extrémité, une dent ou barbe étant formée sensiblement centralement dans ladite découpure entre les épaulements d'extrémité et ayant une hauteur supérieure à l'épaisseur de l'organe de commande de verrouillage autour de ladite découpure.The present invention relates to a lock with a locking member. locking control, such as a bolt or slide for controlling at least one bolt, said control member for lock being slidably mounted under the action of a rotary driver operated by a key cooperating with a security device such as a barrel, a profiled cylinder or a barrel, said rotary driver being accommodated with play angular in a radial slot of a free mounted ring in rotation, said locking control member comprising a substantially longitudinal cutout rectangular forming two end shoulders, one tooth or beard being formed substantially centrally in said cutout between the end shoulders and having a height greater than the thickness of the locking control around said cutout.

Dans une serrure connue de ce type (EP-B-0 659 227), la dent ou barbe forme avec les épaulements une portion de crémaillère coopérant avec l'espace de jeu de l'entraíneur dans la fente et avec les bords de la fente. In a known lock of this type (EP-B-0 659 227), the tooth or beard forms with the shoulders a portion of rack cooperating with the coach's play area in the slot and with the edges of the slot.

Ce fonctionnement spécifique de la serrure connue implique divers défauts de fonctionnement pouvant amener à des blocages.This specific operation of the known lock implies various malfunctions which can lead to blockages.

Un inconvénient est en particulier lié à l'inertie de la bague qui, lorsque la dent n'est pas insérée, peut venir bloquer la dent.One drawback is in particular related to the inertia of the ring which, when the tooth is not inserted, can come block the tooth.

Un autre inconvénient résulte de la coopération du panneton avec la dent, en particulier du fait des variations de cotes de l'organe de sécurité, en général un cylindre profilé dit "panneton européen", et en particulier de l'entraíneur ou panneton, une longueur excessive pouvant amener également un blocage de la serrure.Another disadvantage results from the cooperation of the bit with the tooth, especially due to variations in dimensions of the safety device, usually a cylinder so-called "European bit" profile, and in particular the coach or bit, an excessive length which may also bring a lock of the lock.

La présente invention vise en conséquence à pallier les inconvénients de la serrure connue par EP-B-0 659 227, grâce à un fonctionnement spécifique et une structure caractéristique différents évitant tout risque de blocage dû à l'inertie de la bague et/ou à la longueur de l'entraíneur.The present invention therefore aims to overcome the disadvantages of the lock known from EP-B-0 659 227, thanks to a specific operation and structure different characteristics avoiding any risk of blockage due to the inertia of the ring and / or the length of the coach.

A cet effet, la serrure selon l'invention est caractérisée en ce que l'entraíneur est excentré par rapport à la bague, l'axe de pivotement de l'entraíneur étant plus écarté de l'organe de commande de verrouillage que l'axe de rotation de la bague et la longueur de la dent est telle que la trajectoire de l'extrémité libre de l'entraíneur ne coupe pas la parallèle à la direction de coulissement de l'organe de commande de verrouillage tangente à l'extrémité libre de ladite dent.To this end, the lock according to the invention is characterized in that the coach is offset from the ring, the pivot axis of the coach being further away from the locking control member as the axis of rotation of the ring and the length of the tooth is such that the trajectory of the free end of the coach does not cut not parallel to the sliding direction of the organ tangent locking control at the free end of said tooth.

Contrairement à la serrure antérieure, la portion de crémaillère formée par les épaulements d'extrémité de la dent ne coopère pas avec le jeu angulaire de l'entraíneur dans la fente de la bague, la dent n'entrant jamais en contact avec l'entraíneur, ce qui évite tout risque de blocage. Unlike the front lock, the portion of rack formed by the end shoulders of the tooth does not cooperate with the angular play of the coach in the slot of the ring, the tooth never coming in contact with the coach, which avoids any risk of blocking.

On connaít par ailleurs (EP-A-0 041 217) un système d'entraínement d'un organe de verrouillage au moyen d'un pignon, dans lequel le pignon est en prise avec une bague à dents axiales, une fente recevant un panneton pivotant. Ce document prévoit que le panneton est excentré par rapport à la bague, afin de pouvoir augmenter le diamètre et/ou le nombre de dents de la bague.We also know (EP-A-0 041 217) a system for driving a locking member by means of a pinion, in which the pinion is engaged with a ring axial teeth, a slot receiving a pivoting bit. This document provides that the bit is eccentric with respect to the ring, in order to be able to increase the diameter and / or the number of ring teeth.

L'enseignement de ce document, concernant une serrure d'un type différent et résolvant un problème distinct, ne peut être utilisé, sans activité inventive, pour modifier la serrure selon EP-B-0 659 227, afin d'éviter le blocage de l'organe de verrouillage.The teaching of this document, concerning a lock of a different type and solving a separate problem, cannot be used, without inventive step, to modify the lock according to EP-B-0 659 227, in order to avoid blocking of the locking member.

L'invention sera bien comprise à la lecture de la description suivante, en référence au dessin annexé dans lequel les figures 1 à 6 représentent schématiquement, en vue de face, une partie d'une serrure selon un exemple de réalisation dans diverses positions de fonctionnement.The invention will be clearly understood on reading the following description, with reference to the attached drawing in which Figures 1 to 6 schematically represent, in front view, part of a lock according to an example of realization in various operating positions.

Dans l'exemple représenté, la serrure comprend un organe de commande de verrouillage 1, en pratique un pêne ou un coulisseau de commande, monté coulissant dans un boítier de serrure (non représenté). Un entraíneur 2, commandé en rotation autour de son axe 3 par une clé (non représentée), coopère avec un organe de sécurité constitué, dans l'exemple décrit, par un cylindre profilé 4 appelé également "panneton européen".In the example shown, the lock comprises a member for locking control 1, in practice a bolt or a control slide, slidably mounted in a housing lock (not shown). Coach 2, ordered in rotation around its axis 3 by a key (not shown), cooperates with a security organ constituted, in the example described, by a profiled cylinder 4 called also "European bit".

L'entraíneur 2 est logé avec jeu angulaire dans une fente radiale 5 d'une bague 6 montée libre en pivotement, dans le boítier de serrure, autour de son axe 7.Coach 2 is housed with angular play in a slot radial 5 of a ring 6 mounted to pivot freely, in the lock housing, around its axis 7.

L'organe 1 comporte, au voisinage de son extrémité de commande, une découpure longitudinale 8 sensiblement rectangulaire ménageant deux épaulements d'extrémité 9, 10 qui sont bordés respectivement par deux zones 11, 12 d'épaisseur réduite. Une dent 13, dont la hauteur est égale à toute l'épaisseur de l'organe 1, est formée dans la découpure 8 entre les épaulements 9 et 10.The member 1 comprises, in the vicinity of its end of control, a longitudinal cutout 8 substantially rectangular with two end shoulders 9, 10 which are bordered respectively by two zones 11, 12 reduced thickness. A tooth 13, the height of which is equal at the entire thickness of the member 1, is formed in the cutout 8 between shoulders 9 and 10.

Le dispositif est tel que la bague 6 peut pivoter autour de son axe 7 sous les zones 11, 12 et que, au cours de cette rotation, la fente 5 de la bague 6 peut coopérer avec la dent 13 pour déplacer l'organe de commande de verrouillage 1 en coulissement. La rotation de la bague 6 est commandée par l'entraíneur 2.The device is such that the ring 6 can pivot around its axis 7 under zones 11, 12 and that, during this rotation, the slot 5 of the ring 6 can cooperate with the tooth 13 to move the locking control member 1 sliding. The rotation of the ring 6 is controlled by coach 2.

Conformément à la présente invention, l'axe de pivotement 3 de l'entraíneur 2 est plus écarté de l'organe de commande de verrouillage 1 que l'axe de rotation 7 de la bague 6 de telle manière que l'extrémité libre de l'entraíneur 2 suive une trajectoire qui ne coupe pas la droite 14 parallèle à la direction de déplacement de l'organe 1 et tangente à l'extrémité libre de la dent 13. Cette condition est réalisée également du fait de la longueur réduite de la dent 13.According to the present invention, the pivot axis 3 of the coach 2 is further away from the control member lock 1 as the axis of rotation 7 of the ring 6 of so that the free end of the coach 2 follows a trajectory which does not intersect the straight line 14 parallel to the direction of movement of the member 1 and tangent to the free end of tooth 13. This condition is also achieved due to the reduced length of the tooth 13.

Le fonctionnement de la serrure qui vient d'être décrite est le suivant.The operation of the lock which has just been described is the next.

En position de verrouillage (figure 2), l'organe de commande 1 a été déplacé vers la gauche (sur le dessin) et la dent 13, en butée sur la périphérie de la bague 6, interdit tout mouvement vers la droite.In the locked position (Figure 2), the command 1 has been moved to the left (in the drawing) and the tooth 13, in abutment on the periphery of the ring 6, prohibits any movement to the right.

En partant de cette position, après introduction de la clé, on peut faire pivoter l'entraíneur 2 dans le sens de la flèche F (figure 3) jusqu'à ce que ledit entraíneur 2 entre en contact avec l'épaulement 10. La bague 6 est entraínée dans le même sens par l'entraíneur 2. Si, au cours de cette rotation, la bague 6 tourne plus que l'entraíneur (voir figure 4), il ne se produit aucun blocage de la serrure. Starting from this position, after entering the key, you can rotate the coach 2 in the direction of the arrow F (Figure 3) until said coach 2 enters in contact with the shoulder 10. The ring 6 is driven in the same direction by the coach 2. If, during this rotation, the ring 6 rotates more than the coach (see figure 4), there is no blocking of the lock.

En continuant la rotation de l'entraíneur 2 jusqu'à ce qu'il échappe à l'épaulement 10 (figure 5), on produit un premier déplacement de l'organe de commande de verrouillage d'une amplitude qui est habituellement de l'ordre de 10 mm. A cet instant, le bord avant (dans le sens de rotation) de la fente 5 de la bague 6 entre en contact avec la dent 13 et continue le déplacement de l'organe de commande 1 sur une course qui est également de l'ordre de 10 mm, jusqu'à ce que le bord avant échappe à la dent 13 (figure 6). A partir de cet instant, la dent 13 est en appui sur la périphérie de la bague 6, de sorte que l'organe 1 ne peut pas être repoussé vers la position de verrouillage. Une rotation inverse de l'entraíneur 6 produit une cinématique inverse de passage de l'organe de commande 1 de la position de déverrouillage (figure 5) à la position de verrouillage (figure 2).Continuing the rotation of coach 2 until that it escapes the shoulder 10 (Figure 5), we produce a first movement of the locking control member of an amplitude which is usually of the order of 10 mm. At this time, the front edge (in the direction of rotation) of the slot 5 of the ring 6 comes into contact with the tooth 13 and continues the movement of the control member 1 on a stroke which is also of the order of 10 mm, up to that the front edge escapes the tooth 13 (Figure 6). AT from this moment, tooth 13 is supported on the periphery of the ring 6, so that the member 1 cannot not be pushed back to the locked position. A reverse rotation of the trainer 6 produces kinematics reverse passage of the control member 1 from the position release (Figure 5) to the locked position (figure 2).

La figure 1, agrandie, ne correspond pas à une position effective de la serrure mais est destinée à mettre en évidence les caractéristiques de l'invention.Figure 1, enlarged, does not correspond to a position effective of the lock but is intended to the characteristics of the invention.

On notera que la dent 13, qui ne coopère qu'avec les bords de la fente 5, est à flans droits, ce qui assure une prise positive et sûre avec ces bords.Note that tooth 13, which only cooperates with the edges of slot 5, is at right sides, which ensures a grip positive and safe with these edges.

L'organe de commande de verrouillage 1 est usuellement constitué par une barre, les régions amincies 11, 12 étant usinées dans cette barre alors que la dent 13 occupe toute l'épaisseur de la barre.The locking control member 1 is usually consisting of a bar, the thinned regions 11, 12 being machined in this bar while tooth 13 occupies all the thickness of the bar.

En variante, les épaulements 11, 12 et la dent 13 peuvent être formés sur une pièce rapportée sur l'organe de commande de verrouillage 1.Alternatively, the shoulders 11, 12 and the tooth 13 can be trained on an attachment on the organ of lock control 1.

Afin d'éliminer toute rotation de la bague 6 par inertie, il est possible de lui associer un frein, par exemple sous forme d'un ressort.In order to eliminate any rotation of the ring 6 by inertia, it is possible to associate a brake, for example under form of a spring.
