Description
Serrure à commande électrique
La présente invention concerne une serrure à commande électrique du type comportant un contre-pêne de blocage d'un organe de commande de la serrure tel qu'une béquille, ledit contre-pêne coulissant dans le boîtier de la serrure et, en position de déverrouillage de l'organe de commande, étant logé au moins partiellement dans la gâche de la serrure à travers une ouverture de ladite gâche, l'extrémité libre dudit contre-pêne étant soumise à l'action d'un excentrique de verrouillage solidaire de l'arbre de sortie d'un moteur électrique logé dans la gâche de la serrure.Electrically operated lock
The present invention relates to an electrically operated lock of the type comprising a locking bolt for locking the lock control member such as a handle, said bolt sliding in the lock housing and, in the unlocked position. of the control member, being housed at least partially in the keeper of the lock through an opening of said keeper, the free end of said latch being subjected to the action of a locking eccentric secured to the output shaft of an electric motor housed in the strike plate of the lock.
On connaît déjà une serrure de ce type dans lequel l'excentrique, tel qu'un rouleau monté excentré sur un disque accouplé à l'axe de sortie du moiteur, agit de manière directe sur le contre-pêne pour le faire coulisser jusqu'à une position de verrouillage à laquelle il bloque un organe de commande de la serrure, ledit excentrique repoussant l'extrémité libre du contre-pêne hors de l'ouverture de la gâche, le contre-pêne pouvant occuper une position de déverrouillage à laquelle l'actionnement de l'organe de commande est débloqué, l'excentrique étant écarté de I'extrémité libre du contre-pêne qui est rappelé élastiquement de manière à se loger partiellement dans la gâche au travers de l'ouverture.A lock of this type is already known in which the eccentric, such as a roller mounted eccentrically on a disc coupled to the exit axis of the wetnesser, acts directly on the cons-bolt to make it slide until a locking position at which it blocks a control member of the lock, said eccentric pushing the free end of the latch out of the opening of the strike, the latch can occupy an unlocking position at which the actuation of the control member is released, the eccentric being spaced from the free end of the latch which is resiliently biased so as to be partially housed in the keeper through the opening.
Un tel dispositif, s'il est relativement satisfaisant, présente cependant l'inconvénient d'être accessible par l'extérieur de la gâche et, par conséquent, vulnérable. En effet, en position de verrouillage, il est possible d'intervenir sur l'excentrique à l'aide d'un outil tel qu'un tournevis dont la pointe est introduite entre la gâche et le boîtier de la serrure. Le tournevis agit de manière à entraîner en rotation l'excentrique de manière à l'écarter de l'extrémité libre du contre-pêne de telle sorte que ledit contre-pêne peut coulisser vers sa position de déverrouillage de l'organe de commande, libérant ainsi l'actionnement de la serrure.Such a device, if it is relatively satisfactory, however has the drawback of being accessible from the outside of the keeper and, consequently, vulnerable. Indeed, in the locked position, it is possible to intervene on the eccentric using a tool such as a screwdriver, the point of which is inserted between the keeper and the lock housing. The screwdriver acts so as to rotate the eccentric so as to move it away from the free end of the latch so that said latch can slide towards its unlocking position of the control member, releasing thus actuation of the lock.
Afin de pallier cet inconvénient, l'invention consiste en ce que l'ouverture de passage du contre-pêne dans la gâche est munie d'un volet escamotable vers l'intérieur de ladite gâche.In order to overcome this drawback, the invention consists in that the passage opening of the latch in the keeper is provided with a retractable flap towards the inside of said keeper.
Ainsi, de manière avantageuse, le volet escamotable obture l'ouverture de la gâche et se trouve alors interposé entre l'excentrique et l'extrémité libre du contre-pêne en position de verrouillage du contre-pêne, l'excentrique maintenant ledit volet en position de fermeture de l'ouverture de passage dans la gâche, l'extrémité du contre-pêne ayant été repoussée en coulissement hors de la gâche.Thus, advantageously, the retractable flap closes the opening of the strike and is then interposed between the eccentric and the free end of the latch in the locking position of the latch, the eccentric holding said flap in closed position of the passage opening in the keeper, the end of the latch having been pushed back in sliding out of the keeper.
En conséquence, le volet masque l'excentrique qui ne peut être actionné depuis l'extérieur par un quelconque outil.Consequently, the flap masks the eccentric which cannot be actuated from the outside by any tool.
Lors de l'entraînement en rotation de l'excentrique vers la position de déverrouillage du contre-pêne, l'excentrique s'écarte du volet escamotable et le contre-pêne rappelé élastiquement dans l'ouverture de la gâche repousse le volet escamotable vers l'intérieur.During the rotary drive of the eccentric to the unlocking position of the latch, the eccentric moves away from the retractable flap and the latch returned elastically in the opening of the strike pushes the retractable flap towards the inside.
Selon un mode de réalisation préféré de l'invention, le volet escamotable est rappelé élastiquement en position d'obturation de l'ouverture du passage de sorte que, lorsqu'on entraîne en rotation l'excentrique vers l'ouverture de manière à amener le contre-pêne à la position de verrouillage, l'excentrique repousse ledit contre-pêne mais également le volet escamotable. Celui-ci étant rappelé élastiquement vers sa position d'obturation de l'ouverture, il ne perturbe pas la manoeuvre. De même, lorsqu'en position de déverrouillage on actionne la serrure, le contre-pêne est entraîné en coulissement hors de l'ouverture de la gâche et le volet escamotable revient masquer ladite ouverture alors même que l'excentrique n'a pas été actionné par le moteur.According to a preferred embodiment of the invention, the retractable flap is resiliently returned to the closed position of the opening of the passage so that, when the eccentric is driven in rotation towards the opening so as to bring the counter-bolt in the locking position, the eccentric pushes said counter-bolt but also the retractable flap. The latter being resiliently returned to its closed position of the opening, it does not disturb the operation. Similarly, when in the unlocking position the lock is actuated, the latch bolt is slidably driven out of the opening of the keeper and the retractable flap returns to hide said opening even when the eccentric has not been actuated by the engine.
De préférence, la serrure à commande électrique est une serrure à fonction anti-panique du type à simple fouillot ou à double fouillot, le contre-pêne permettant le verrouillage et le déverrouillage de l'organe de commande de la serrure tel que la béquille situé du côté extérieur de la porte.Preferably, the electrically controlled lock is a lock with anti-panic function of the single follower or double follower type, the latch allowing the locking and unlocking of the control member of the lock such as the crutch located on the outside of the door.
On décrira maintenant plus en détail une serrure à commande électrique selon un exemple de réalisation de l'invention en référence au dessin annexé dans lequel les figures la et lb représentent une vue en coupe de la gâche et du contre-pêne d'une serrure selon l'état de la technique respectivement à la position de déverrouillage et la position de verrouillage dudit contre-pêne les figures 2a et 2b représentent une vue en coupe de la gâche et du contre-pêne d'une serrure selon l'invention respectivement à la position de déverrouillage et à la position de verrouillage dudit contre-pêne ; et la figure 3 représente une vue en perspective d'une gâche d'une serrure selon l'invention.An electrically controlled lock according to an exemplary embodiment of the invention will now be described in more detail with reference to the accompanying drawing in which FIGS. 1a and 1b show a sectional view of the keeper and the bolt of a lock according to the state of the art respectively in the unlocking position and the locking position of said latch FIGS. 2a and 2b represent a sectional view of the strike plate and the latch bolt of a lock according to the invention respectively unlocking position and the locking position of said latch; and Figure 3 shows a perspective view of a keeper of a lock according to the invention.
Le contre-pêne 1 d'une serrure à commande électrique permet de bloquer l'actionnement d'un organe de commande d'une serrure tel que la béquille, l'extrémité chanfreinée libre la dudit contre-pêne 1 pouvant coulisser à cet effet dans le boîtier de la serrure (non représenté) de manière à s'engager au travers d'une ouverture 2 ménagée en regard dans la gâche 3 de la serrure. L'extrémité la du contre-pêne 1 coopère avec un excentrique 4 de verrouillage solidaire de l'arbre de sortie 5 d'un moteur électrique logé dans ladite gâche 3.The latch 1 of an electrically controlled lock makes it possible to block the actuation of a control member of a lock such as the crutch, the free chamfered end 1a of said latch 1 being able to slide for this purpose in the lock housing (not shown) so as to engage through an opening 2 arranged opposite in the keeper 3 of the lock. The end 1a of the latch 1 cooperates with a locking eccentric 4 secured to the output shaft 5 of an electric motor housed in said keeper 3.
Cet excentrique 4 est constitué d'un rouleau 6 monté excentré sur un disque 7 solidaire de l'arbre de sortie 5 du moteur, l'axe de l'arbre de sortie 5 et l'axe x du rouleau 6 s'étendant orthogonalement à l'axe de translation du contrepêne 1.This eccentric 4 consists of a roller 6 mounted eccentrically on a disc 7 integral with the output shaft 5 of the motor, the axis of the output shaft 5 and the x axis of the roller 6 extending orthogonally to the axis of translation of the brace 1.
Comme on peut le voir à la figure la, lorsque le contre-pêne 1 est engagé dans l'ouverture 2 sous l'effet de moyens de rappel élastique, le rouleau excentré 6 est écarté de l'extrémité la dudit contre-pêne 1, l'actionnement de la béquille est alors libre.As can be seen in FIG. 1a, when the latch 1 is engaged in the opening 2 under the effect of elastic return means, the eccentric roller 6 is moved away from the end 1a of said latch 1, the actuation of the stand is then free.
Pour condamner l'actionnement de la béquille, il convient de faire passer le contre-pêne 1 à sa position de verrouillage, on entraîne alors le moteur en rotation dans le sens de la flèche A de sorte que le rouleau excentré 6 porté par le disque 7 vient buter contre le pan incliné de l'extrémité libre la du contre-pêne 1 et provoque le coulissement de ce dernier vers le boîtier de la serrure de sorte que ledit contre-pêne 1 ne traverse plus l'ouverture 2 de la gâche 3, comme cela est visible à la figure lb.To condemn the actuation of the stand, it is necessary to pass the latch 1 to its locked position, then the motor is rotated in the direction of the arrow A so that the eccentric roller 6 carried by the disc 7 abuts against the inclined face of the free end 1a of the latch 1 and causes the latter to slide towards the lock housing so that said latch 1 no longer crosses the opening 2 of the keeper 3 , as shown in Figure lb.
Cependant comme on peut le voir à la figure lb, l'utilisation d'un outil tel qu'un tournevis 8 permet d'agir sur le rouleau excentré 6 afin de provoquer l'entraînement en rotation de l'ensemble vers une position écartée de l'extrémité la dudit contre-pêne 1. De ce fait, le contre-pêne 1 rappelé élastiquement est libre de s'engager à nouveau au travers de l'ouverture 2 vers la position de déverrouillage du blocage de la béquille libérant ainsi l'actionnement de la serrure.However, as can be seen in FIG. 1b, the use of a tool such as a screwdriver 8 makes it possible to act on the eccentric roller 6 in order to cause the drive in rotation of the assembly towards a position separated from the end of said counter-bolt 1. As a result, the counter-bolt 1 which is resiliently recalled is free to engage again through the opening 2 towards the unlocking position of the crutch blocking thereby releasing the actuation of the lock.
Afin de protéger cette position de verrouillage, l'ouverture de la gâche d'une serrure selon l'invention est munie d'un volet escamotable 9 vers l'intérieur de ladite gâche 3.In order to protect this locking position, the opening of the strike plate of a lock according to the invention is provided with a retractable flap 9 towards the inside of said strike plate 3.
Ce volet 9 est monté pivotant par un de ses bords latéraux 9asur un côté de l'ouverture 2 de la gache 3 tandis que le bord latéral opposé 9b est, en position non escamotée, en butée contre le côté opposé de l'ouverture 2 à l'intérieur de la gâche 3, les dimensions du volet 9 étant telles que l'ouverture 2 est parfaitement obturée. De préférence, ledit volet 9 est monté dans l'ouverture 2 de maniere à être rappelé élastiquement en position d'obturation de ladite ouverture 2 par exemple à l'aide d'un moyen de rappel élastique approprié tel qu'un ressort 10.This flap 9 is pivotally mounted by one of its lateral edges 9 on one side of the opening 2 of the keeper 3 while the opposite lateral edge 9b is, in the not retracted position, in abutment against the opposite side of the opening 2 to inside the keeper 3, the dimensions of the flap 9 being such that the opening 2 is perfectly closed. Preferably, said flap 9 is mounted in opening 2 so as to be resiliently returned to the closed position of said opening 2, for example using an appropriate elastic return means such as a spring 10.
Ainsi, lorsque le contre-pêne 1 est à la position de déverrouillage de l'actionnement de la béquille (figure 2a), l'extrémité la dudit contre-pêne 1 repousse le volet 9 vers l'intérieur de la gâche 3, le rouleau excentré 6 étant écarté de ladite extrémité la du contre-pêne 1, et le volet 9 se trouve alors interposé entre ltextrémité la du contre-pêne 1 et le rouleau excentré 6.Thus, when the latch 1 is in the unlocking position of the actuation of the stand (FIG. 2a), the end 1a of said latch 1 pushes the flap 9 towards the interior of the keeper 3, the roller eccentric 6 being spaced from said end 1a of the latch 1, and the flap 9 is then interposed between the end 1a of the latch 1 and the eccentric roller 6.
Lorsqu'on amène le contre-pêne 1 à sa position de verrouillage de l'actionnement de la béquille (figure 2b), le rouleau excentré 6 est entraîné en rotation par l'intermédiaire du disque 7 selon le sens de rotation représenté par la flèche A et repousse l'extrémité la du contre-pêne 1. Le volet escamotable 9 toujours interposé entre ledit rouleau 6 et l'extrémité la ne s'oppose pas à ce mouvement puisque ceci correspond à son déplacement sous l'effet du rappel élastique vers l'obturation de l'ouverture 2.When the counter-bolt 1 is brought to its position for locking the actuation of the stand (FIG. 2b), the eccentric roller 6 is driven in rotation via the disc 7 according to the direction of rotation represented by the arrow A and pushes the end 1a of the counter-bolt 1. The retractable flap 9 always interposed between said roller 6 and the end 1a does not oppose this movement since this corresponds to its movement under the effect of the elastic return towards shutter opening 2.
De préférence afin de faciliter l'entraînement en rotation du rouleau excentré 6 autour de son axe x au cours des différents déplacements de celui-ci contre la face interne du volet 9, celui-ci présente une forme légèrement recourbée vers l'intérieur de la gâche à son extrémité libre 9b opposé à son bord latéral monté pivotant dans l'ouverture 2.Preferably in order to facilitate the rotational drive of the eccentric roller 6 around its axis x during the various displacements of the latter against the internal face of the shutter 9, the latter has a slightly curved shape towards the inside of the keeper at its free end 9b opposite its lateral edge pivotally mounted in the opening 2.
Ainsi, comme on peut le voir à la figure 2b, il n'est pas possible d'agir sur le rouleau excentré 6 lorsque le contrepêne 1 est en position de verrouillage du blocage de la béquille, le volet 9 masquant totalement l'intérieur de la gâche 3 et le rouleau excentré 6.Thus, as can be seen in FIG. 2b, it is not possible to act on the eccentric roller 6 when the brace 1 is in the locking position for locking the stand, the flap 9 completely masking the interior of keeper 3 and eccentric roller 6.
On obtient ainsi une serrure à commande électrique dont le blocage d'un organe de manoeuvre tel qu'une béquille obtenu par un contre-pêne est sûr. An electrically controlled lock is thus obtained, the blocking of an operating member such as a crutch obtained by a counter bolt is secure.
