Description

La présente invention concerne une serrure pour véhicule automobile.The present invention relates to a lock for a motor vehicle.

Plus particulièrement, l'invention concerne une serrure du type comportant un boitier solidaire d'une première partie du véhicule, dans lequel est disposé un pène associé à des moyens de verrouillage et/ou de déverrouillage, et une gäche solidaire d'une seconde partie du véhicule, adaptée pour coopérer avec le pène, l'une desdites première et seconde parties du véhicule étant mobile par rapport à l'autre et le pène étant monté articulé entre une position de libération et une position de verrouillage de la gäche.More particularly, the invention relates to a lock of the type comprising a box secured to a first part of the vehicle, in which is disposed a bolt associated with locking and / or unlocking means, and a lock secured to a second part of the vehicle, adapted to cooperate with the bolt, one of said first and second parts of the vehicle being movable relative to the other and the bolt being mounted articulated between a release position and a latching position.

Les serrures de l'état de la technique présentent un certain nombre d'inconvénients notamment au niveau du verrouillage de la gäche par le pène qui nécessite un effort important, se traduisant par exemple par la nécessité de fermer vigoureusement le hayon du véhicule.Locks of the state of the art have a certain number of drawbacks, in particular with regard to the locking of the keeper by the bolt which requires considerable effort, resulting for example in the need to vigorously close the tailgate of the vehicle.

Le document US 3 321 226 illustre une solution pour la fermeture automatique d'une partie mobile de véhicule à l'aide d'une serrure motorisée. Dans cette solution, un seul et unique constituant, à savoir une gäche mobile, qui est entraînée à l'aide d'un moteur, assure à la fois et l'accostage/accrochage d'un pène solidaire de la partie mobile et le verrouillage de ce pène lorsque cette partie mobile est fermée. Il y a lieu d'observer que cette gäche lorsqu'elle assure le verrouillage du pène peut aussi être commandée manuellement à l'aide d'une clé ce qui ne met pas la serrure à l'abri des tentavives d'effraction.Document US 3,321,226 illustrates a solution for the automatic closing of a moving part of a vehicle using a motorized lock. In this solution, a single and unique component, namely a movable keeper, which is driven using a motor, ensures both the docking / hooking of a bolt secured to the movable part and the locking of this bolt when this movable part is closed. It should be noted that this strike when it secures the bolt can also be controlled manually using a key, which does not protect the lock from tampering.

Le but de l'invention est donc de résoudre ce genre d'inconvénients en proposant une serrure qui permette de verrouiller en douceur la gäche dans le boltier, tout en conservant l'efficacité du verrouilage et en permettant à l'utilisateur d'actionner à tout moment les moyens de déverrouillage de celle-ci.The object of the invention is therefore to solve this kind of drawback by proposing a lock which allows the lock to be locked gently in the boltier, while retaining the effectiveness of the locking. and allowing the user to activate the unlocking means at any time.

A cet effet, l'invention a pour objet une serrure d'un type analogue à celui exposé dans ce document et dont ceux des constituants nécessaires à l'invention sont rappelés dans le préambule de la revendication principale alors que les particularités distinctives de l'invention ressortent notamment de la partie caractérisante de cette revendication.To this end, the subject of the invention is a lock of a type similar to that set out in this document and of which those of the constituents necessary for the invention are recalled in the preamble to the main claim while the distinctive features of the invention emerge in particular from the characterizing part of this claim.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant au dessin annexé qui représente une vue en coupe d'une serrure selon l'invention, la gäche étant montrée dans plusieurs de ses positions.The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawing which represents a sectional view of a lock according to the invention, the keeper being shown in several of its positions.

Ainsi qu'il est représenté sur cette figure, une serrure selon l'invention, pour véhicule automobile, comporte un boltier 1 solidaire d'une première partie 2 du véhicule et dans lequel est disposé un péne 3 associé à des moyens de verrouillage et/ou de déverrouillage 4. La serrure comporte également une gäche 5, adaptée pour coopérer avec le pène et solidaire d'une seconde partie 6 du véhicule par exemple montée mobile par rapport à la première partie 2 de celui-ci.As shown in this figure, a lock according to the invention, for a motor vehicle, comprises a bolt holder 1 secured to a first part 2 of the vehicle and in which a latch 3 is arranged associated with locking means and / or unlocking 4. The lock also includes a keeper 5, adapted to cooperate with the bolt and secured to a second part 6 of the vehicle, for example mounted movable relative to the first part 2 thereof.

Ainsi qu'il est connu, le pène est monté articulé entre une position de libération et une position de verrouillage de la gäche. Le pène comporte par exemple deux épaulements 3a et 3b destinés à coopérer avec une surface de butée 7 d'un organe de verrouillage 8 du pène, le pène étant sollicité vers sa position de libération de la gäche par des moyens élastiques (non représentés). Cet organe de verrouillage 8 présente la forme générale d'un U articulé en 8a dans le boitier et sollicité vers le pène pour définir les deux positions de celui-ci. Une tringle d'actionnement 9 permet de dégager la surface de butée 7 de l'organe de verrouillage de l'épaulement 3a du pène définissant la position de verrouillage du pène, de manière à assurer la libération de la gäche.As is known, the bolt is mounted articulated between a release position and a locking position of the strike. The bolt comprises for example two shoulders 3a and 3b intended to cooperate with an abutment surface 7 of a locking member 8 of the bolt, the bolt being urged towards its position for releasing the latch by means elastic (not shown). This locking member 8 has the general shape of a U articulated at 8a in the case and urged towards the bolt to define the two positions of the latter. An actuating rod 9 makes it possible to release the abutment surface 7 from the locking member of the shoulder 3a of the bolt defining the locking position of the bolt, so as to ensure the release of the keeper.

La serrure selon l'invention comporte également, disposé dans le boitier, un organe 10 de déplacement de la gäche 5. Cet organe de déplacement comprend des moyens d'accrochage 11 de cette gäche, et est monté déplaçable, ainsi qu'il est illustré sur cette figure, entre une position d'accrochage A de la gäche, cet accrochage étant réalisé par manoeuvre de la partie mobile du véhicule par l'utilisateur, et une position de verrouillage 8 de la gäche par le pène. Ce déplacement est assuré par l'intermédiaire de moyens d'actionnement 12 commandés dans un sens, c'est à dire de la position d'accrochage A de la gäche 5 par les moyens d'accrochage 11 de l'organe de déplacement vers la position de verrouillage 8 de la gäche par le pène, par des moyens d'indication de la présence de cette gäche en position d'accrochage, et dans l'autre sens, c'est à dire de la position de verrouillage 8 de la gäche par le pène vers la position d'accrochage A, par des moyens d'indication de l'actionnement des moyens de verrouillage 4 du pène.The lock according to the invention also comprises, arranged in the housing, a member 10 for moving the strike 5. This movement member comprises means 11 for hooking this strike, and is mounted to be moved, as illustrated. in this figure, between a latching position A of the striker, this latching being produced by maneuvering the movable part of the vehicle by the user, and a locking position 8 of the striker by the bolt. This movement is ensured by means of actuation means 12 controlled in one direction, that is to say from the hooking position A of the keeper 5 by the hooking means 11 of the movement member towards the locking position 8 of the strike by the bolt, by means of indicating the presence of this strike in the hooked position, and in the other direction, that is to say of the locking position 8 of the strike by the bolt towards the hooking position A, by means of indication of the actuation of the locking means 4 of the bolt.

Ces moyens d'indication sont par exemple constitués par un interrupteur actionné par la gäche ou l'organe de déplacement lors de la venue de la gäche en position d'accrochage, pour les moyens d'indication de la présence de la gäche en position d'accrochage A et par un interrupteur actionné par lesdits moyens de déverrouillage lors de leur actionnement, pour les moyens d'indication de l'actionnement des moyens de déverrouillage du pène.These indication means are for example constituted by a switch actuated by the strike or the displacement member when the strike comes in the hooked position, for the means of indicating the presence of the strike in position d 'hooking A and by a switch actuated by said unlocking means during their actuation, for the means for indicating the actuation of the bolt unlocking means.

Il est également à noter que des interrupteurs de fin de course en positions d' accrochage A et de verrouillage B, de l'organe de déplacement, sont prévus pour couper l'alimentation des moyens d'actionnement 12.It should also be noted that end-of-travel switches in the hooking A and locking B positions of the displacement member are provided to cut off the supply to the actuating means 12.

Les moyens d accrochage 11 de l organe de déplacement 10 comprennent un crochet, déplaçable entre une position active vers laquelle il est sollicité élastiquement et dans laquelle il s'étend dans le trajet de déplacement de la gâche 5, et une position escamotée de manière à permettre l'accrochage ou la libération de la gâche.The hooking means 11 of the displacement member 10 comprise a hook, movable between an active position towards which it is resiliently stressed and in which it extends in the path of movement of the keeper 5, and a retracted position so as to allow the latching or release of the keeper.

Le crochet comporte par exemple une surface inclinée 11a avec laquelle coopère la gâche 5 pour déplacer celui-ci vers sa position escamotée, lors de l' accrochage de la gâche.The hook comprises for example an inclined surface 11a with which the keeper 5 cooperates to move the latter towards its retracted position, when the strike is hooked.

Par ailleurs, des moyens 13 d'escamotage de l'organe de déplacement sont également prévus pour escamoter celui-ci lors d'un actionnement des moyens de déverrouillage 4 du pène. Ces moyens sont par exemple constitués par une came 14 articulée sur le pène 3 et reliée aux moyens de déverrouillage 4 du pène par une tringle de manoeuvre 15.Furthermore, means 13 for retracting the displacement member are also provided for retracting the latter when the unlocking means 4 of the bolt are actuated. These means are for example constituted by a cam 14 articulated on the bolt 3 and connected to the unlocking means 4 of the bolt by an operating rod 15.

L'organe de déplacement 10 présente la forme générale d'un S. L'une des extrémités de celui-ci comprend les moyens d'accrochage 11 tels que décrits précédement, et l'autre est articulée en 11b sur un coulisseau 16 monté déplaçable dans le boîtier 1 par les moyens d' actionnement 12, de manière à entrainer un déplacement de l'organe de déplacement 10 de la gâche entre les deux positions mentionnées précédemment.The displacement member 10 has the general shape of an S. One of the ends thereof comprises the hooking means 11 as described above, and the other is articulated at 11b on a slide 16 mounted movable in the housing 1 by the actuating means 12, so as to cause a displacement of the movement member 10 of the keeper between the two positions mentioned above.

Il est à noter que l'organe de déplacement 10 est sollicité élastiquement vers sa position active par un ressort 17 dont l'une des extrémités est en appui sur le coulisseau 16 et l'autre, sur l'organe 10.It should be noted that the displacement member 10 is resiliently biased towards its active position by a spring 17, one end of which bears on the slide 16 and the other on the member 10.

Les moyens d actionnement 12 mentionnés précédemment, comportent par exemple un moto-réducteur 18 dont l'arbre de sortie coopère avec des moyens d'entraînement 19 de l'organe de déplacement 10 pour le déplacer entre ses deux positions. Ces moyens d entraînement 19 comportent une roue dentée 20 solidaire de l'arbre de sortie du moto-réducteur 18 et destinée à coopérer avec des formes complémentaires d'une bande d'entraînement 21 montée déplaçable dans une glissière 22 solidaire du boitier 1, une extrémité de cette bande étant solidaire du coulisseau 16. Il est à noter que cette glissière 22 s'étend entre les deux branches de l'organe de verrouillage 8. Il va de soi que d'autres modes de réalisation sont possibles. Ainsi, le coulisseau peut être venu de matière avec la bande.The actuation means 12 mentioned above, for example comprise a geared motor 18 whose output shaft cooperates with drive means 19 of the movement member 10 to move it between its two positions. These drive means 19 comprise a toothed wheel 20 integral with the output shaft of the geared motor 18 and intended to cooperate with complementary forms of a drive band 21 mounted movably in a slide 22 integral with the housing 1, a end of this strip being integral with the slide 16. It should be noted that this slide 22 extends between the two branches of the locking member 8. It goes without saying that other embodiments are possible. Thus, the slide may have come integrally with the strip.

Le fonctionnement d'un tel dispositif est le suivant.The operation of such a device is as follows.

Lorsque l'utilisateur déplace par exemple la partie mobile du véhicule sur laquelle est fixée la gâche vers la position d'accrochage A, la gâche coopère avec la surface inclinée 11a du crochet de l'organe de déplacement 10 pour déplacer celui-ci vers sa position escamotée et permettre à la gâche de franchir le crochet et d'arriver dans la position d' accrochage.When the user moves for example the mobile part of the vehicle on which the keeper is fixed towards the hooking position A, the keeper cooperates with the inclined surface 11a of the hook of the movement member 10 to move the latter towards its retracted position and allow the keeper to cross the hook and arrive in the hooking position.

Dans cette position, les moyens de détection de la présence de la gâche en position d'accrochage alimentent le moto-réducteur 18 dans un certain sens pour que celui-ci entraîne un déplacement de la bande d'entrainement 21 et donc du coulisseau 16 et de l'organe de déplacement 10 vers la position de verrouillage B de la gâche par le pène.In this position, the means for detecting the presence of the keeper in the hooking position feed the gear motor 18 in a certain direction so that it causes a displacement of the drive belt 21 and therefore of the slide 16 and from the movement member 10 to the locking position B of the striker by the bolt.

L'organe de déplacement amène alors automatiquement la gâche 5 en position de verrouillage B, dans laquelle l'épaulement 3a du pène coopère avec la surface de butée 7 de l'organe de verrouillage 8 pour bloquer la gâche en position de verrouillage. Lorsque la gâche est dans cette position de verrouillage, un interrupteur de fin de course détecte cette présence et coupe l'alimentation du moto-réducteur 18 de manière à arrêter le déplacement de l'organe de déplacement 10.The movement member then automatically brings the keeper 5 into the locked position B, in which the shoulder 3a of the bolt cooperates with the abutment surface 7 of the lock member 8 to block the keeper in the locked position. When the keeper is in this locking position, an end-of-travel switch detects this presence and cuts off the power to the gear motor 18 so as to stop the movement of the movement member 10.

Lorsque l'utilisateur désire déverrouiller la gâche, il actionne les moyens 4 de déverrouillage du pêne par l'intermédiaire de la tringle de manoeuvre 9, ce qui entraîne un relâchement du pène vers sa position de libération de la gâche, un actionnement de la came 14 par la tringle 15 solidaire des moyens de déverrouillage, pour escamoter l'organe de déplacement et libérer totalement la gâche et enfin une alimentation du moto-réducteur 18 dans le sens opposé au précédent de manière à permettre une remontée de l'organe de déplacement vers la position d'accrochage. Un interrupteur de fin de course détecte l'arrivée de l' organe de déplacement dans la position d'accrochage et coupe l'alimentation du moto-réducteur de manière à arrêter le déplacement de l'organe de déplacement qui est alors prêt pour un autre cycle de verrouillage.When the user wishes to unlock the keeper, he actuates the means 4 for unlocking the bolt by means of the operating rod 9, which results in a relaxation of the bolt towards its strike release position, an actuation of the cam 14 by the rod 15 secured to the unlocking means, to retract the displacement member and completely release the keeper and finally a supply of the gear motor 18 in the opposite direction to the previous one so as to allow the displacement member to be raised towards the hanging position. A limit switch detects the arrival of the movement member in the latching position and cuts the power to the gear motor so as to stop the movement of the movement member which is then ready for another lock cycle.

Dans la description, les différents interrupteurs de détection et de fin de course n'ont pas été décrits dans le détail car ces types d'interrupteurs sont bien connus en soi et ne présentent pas de difficultés particulières de mise en oeuvre,In the description, the various detection and limit switches have not been described in detail since these types of switches are well known per se and do not present any particular difficulties of implementation,

L'organe de déplacement 10 constitue donc des moyens d'assistance au déplacement de la gâche entre une position d'accrochage dans laquelle la gâche est amenée par l'utilisateur en manoeuvrant par exemple la partie mobile du véhicule, dont est solidaire cette gâche, et une position de verrouillage de cette gâche dans le boitier de serrure, par le pène.The movement member 10 therefore constitutes means for assisting the movement of the keeper between a hooking position in which the keeper is brought by the user by maneuvering for example the mobile part of the vehicle, of which this strike is integral, and a position for locking this strike in the lock box, by the bolt.

Par ailleurs, et ainsi que cela a été décrit, l'utilisateur peut à tout moment du cycle de verrouillage, libérer la gâche en actionnant les moyens de déverrouillage du pène.Furthermore, and as has been described, the user can at any time during the locking cycle, release the keeper by actuating the means for unlocking the bolt.
