Description

La présente invention concerne une serrure, notamment pour véhiclue automobile.The present invention relates to a lock, in particular for a motor vehicle.

Plus particulièrement, l'invention concerne une serrure du type comportant un boîtier solidaire d'une première partie du véhicule, et dans lequel est disposé un pène, et une gâche solidaire d'une seconde partie du véhicule et adaptée pour coopérer avec ledit pène, lesdites première et seconde parties du véhicule étant mobiles l'une par rapport à l'autre et le pène étant monté déplaçable entre une position de libération de la gâche et une position de verrouillage de celle-ci dans le boîtier.More particularly, the invention relates to a lock of the type comprising a housing secured to a first part of the vehicle, and in which a bolt is arranged, and a keeper secured to a second part of the vehicle and adapted to cooperate with said bolt, said first and second parts of the vehicle being movable relative to each other and the bolt being mounted movable between a release position of the keeper and a position of locking the latter in the housing.

Les serrures de l'état de la technique présentent un certain nombre d'inconvénients, notamment au niveau du verrouillage de la gâche par le pène qui nécessite un effort important, se traduisant par exemple par la nécessité de fermer vigoureusement le hayon du véhicule.The 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 significant effort, resulting for example in the need to vigorously close the tailgate of the vehicle.

Une serrure de ce type est par exemple décrite dans le document US-A 3 321 226. Les éléments intéressants de la solution proposée figurent dans le préambule de la revendication principale. Toutefois, du fait de la présence d'une sécurité à clé apparente cette serrure n'est pas exempte de risque face à des tentatives de vol.A lock of this type is for example described in document US-A 3 321 226. The interesting elements of the proposed solution appear in the preamble to the main claim. However, due to the presence of an apparent key security, this lock is not free from risk in the event of attempted theft.

Le but de l'invention est donc de résoudre ce problème en proposant une serrure qui permette de verrouiller en douceur la gâche dans le boîtier, tout en conservant l'efficacité du verrouillage 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 problem by proposing a lock which makes it possible to gently lock the keeper in the housing, while retaining the effectiveness of the locking and by allowing the user to actuate the means for unlocking the latter.

L'invention a pour objet une serrure du type de celle indiquée dans le préambule de la revendication principale et dont les particularités sont exposées notamment dans la partie caractérisante de celle-ci.The subject of the invention is a lock of the type indicated in the preamble to the main claim and the features of which are set out in particular in the characterizing part thereof.

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 gâche 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, comprend un boîtier 1 solidaire d'une première partie 2 du véhicule et dans lequel est disposé un pène 3. La serrure comporte également une gâche 4, adaptée pour coopérer avec le pène et solidaire d'une seconde partie 5 du véhicule, par exemple montée mobile par rapport à la première partie 2 de celui-ci, et déplaçable par l'utilisateur.As shown in this figure, a lock according to the invention, for a motor vehicle, comprises a housing 1 secured to a first part 2 of the vehicle and in which is provided a bolt 3. The lock also includes a keeper 4 , adapted to cooperate with the bolt and secured to a second part 5 of the vehicle, for example mounted movable relative to the first part 2 thereof, and movable by the user.

Le pène 3 comprend des moyens d'accrochage 6 de la gâche et est monté déplaçable le long d'un trajet à peu près parallèle au trajet de déplacement de la gâche au voisinage du boîtier, entre une position d'accrochage de la gâche, illustrée par la flèche A sur cette figure, l'accrochage étant réalisé par manoeuvre de ladite partie mobile du véhicule par l'utilisateur, et une position de verrouilage de la gâche, illustrée par la flèche B, par l'intermédiaire de moyens d'actionnement 7 commandés dans un sens, c'est à dire de la position d'accrochage A vers la position de verrouillage B, par des moyens d'indication de la présence de la gâche en position d'accrochage, et dans l'autre sens, c'est à dire de la position de verrouillage B vers la position d'accrochage A, par des moyens d'indication de l'actionnement de moyens de déverrouillage du pène.The bolt 3 comprises means for hooking the keeper 6 and is mounted movable along a path approximately parallel to the path for moving the keeper in the vicinity of the housing, between a position for hooking the keeper, illustrated by arrow A in this figure, the attachment being achieved by maneuvering said movable part of the vehicle by the user, and a position for locking the keeper, illustrated by arrow B, by means of actuation means 7 controlled in one direction, that is to say from the hooking position A towards the locking position B, by means of indicating the presence of the keeper in the hooking position, and in the other direction, that is to say from the locking position B to the hooking position A, by means of indication of the actuation of means for unlocking the bolt.

Ces moyens d'indication sont par exemple constitués par un interrupteur actionné par la gâche ou le pène lors de la venue de la gâche en position d'accrochage, pour les moyens d'indication de la présence de la gâche en position d'accrochage A, et par un interrupteur actionné par l'utilisateur lorsqu'il désire déverrouiller la serrure, 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 bolt when the strike comes in the hooked position, for the means of indicating the presence of the strike in the hooked position A , and by a switch actuated by the user when he wishes to unlock the lock, for the means for indicating the actuation of the bolt unlocking means.

Il est également à noter que des interrupteurs de fin de course sont prévus en positions d'accrochage A et de verrouillage B du pène, pour couper l'alimentation des moyens d'actionnement 7 et arrêter le déplacement du pène.It should also be noted that limit switches are provided in the hooking A and locking B positions of the bolt, to cut off the power supply to the actuating means 7 and stop the movement of the bolt.

Les moyens d'accrochage 6 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, et une position escamotée de manière à permettre l'accrochage ou la libération de la gâche.The attachment means 6 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, and a retracted position so as to allow the attachment or the release of the striker.

Le crochet 6 comporte par exemple une surface inclinée 6a avec laquelle coopère la gâche 4 pour déplacer celui-ci vers sa position escamotée lors de l'accrochage de cette gâche.The hook 6 comprises for example an inclined surface 6a with which the keeper 4 cooperates to move the latter towards its retracted position when this strike is hooked.

Par ailleurs, des moyens 8 d'escamotage du pène à la suite d'un actionnement des moyens de déve- rouillage de celui-ci sont également prévus. Ces moyens seront décrits plus en détail par la suite.Furthermore, means 8 for retracting the bolt following an actuation of the means for unlocking the latter are also provided. These means will be described in more detail below.

Le pène 3 présente la forme générale d'un S. L'une des extrémités de ce pène comprend les moyens d'accrochage 6 déjà mentionnés précédemment, et sa partie centrale est articulée sur un coulisseau 10 déplaçable dans le boîtier 1 par les moyens d'actionnement 7 de manière à entrainer un déplacement du pène entre ses deux positions.The bolt 3 has the general shape of an S. One of the ends of this bolt comprises the hooking means 6 already mentioned above, and its central part is articulated on a slide 10 movable in the housing 1 by the means d actuation 7 so as to cause a displacement of the bolt between its two positions.

A l'autre de ses extrémités, le pène comprend des surfaces de portée 3a, 3b adaptées pour coopérer avec une première surface de butée 1 a du boîtier et les moyens d'escamotage 8 mentionnés précédemment pour bloquer celui-ci en position de verrouillage et l'escamoter lors de son retour vers la position d'accrochage, respectivement.At the other of its ends, the bolt comprises bearing surfaces 3a, 3b adapted to cooperate with a first abutment surface 1a of the housing and the retraction means 8 mentioned previously to block the latter in the locked position and retract it when it returns to the hooking position, respectively.

A cet effet, les moyens d'escamotage 8 comprennent un organe de butée 9 articulé dans le boîtier entre une position active vers laquelle il est sollicité élastiquement, et une position escamotée. Cet organe de butée comprend des surfaces d'appui 9a, 9b adaptées pour coopérer avec les surfaces de portée 3a, 3b du pène pour déplacer ledit organe de butée vers sa position escamotée lors d'un déplacement du pène vers sa position de verouillage, à l'encontre de moyens élastiques 11 sollicitant l'organe de butée vers sa position active. Ainsi, lors d'un déplacement du pène de sa position d'accrochage A vers sa position de verrouillage B, l'extrémité correspondante du pène oblige l'organe de butée à s'escamoter jusqu'à ce que cette extrémité du pène ait franchi complètement l'organe de butée. Celui-ci revient ensuite dans sa position active. Dans cette position, l'organe de butée est en appui contre une seconde surface de butée 1 b du boîtier et la première surface de butée 1 a de celui-ci, bloque le pène en position de verrouillage.To this end, the retraction means 8 comprise a stop member 9 articulated in the housing between an active position towards which it is urged elastically, and a retracted position. This abutment member comprises bearing surfaces 9a, 9b adapted to cooperate with the bearing surfaces 3a, 3b of the bolt to move said abutment member towards its retracted position when the bolt moves towards its locking position, at against elastic means 11 urging the stop member towards its active position. Thus, during a displacement of the bolt from its hooking position A to its locking position B, the corresponding end of the bolt forces the abutment member to retract until this end of the bolt has crossed the stop member completely. It then returns to its active position. In this position, the stop member is in abutment against a second stop surface 1b of the housing and the first re abutment surface 1a thereof, blocks the bolt in the locked position.

Lorsque les moyens d'actionnement 7 sont commandés de manière à assurer un déplacement du pè- ne 3 de la position de verrouillage B vers la position d'accrochage A, l'extrémité correspondante du pè- ne et plus particulièrement la surface de portée 3a de celui-ci, vient en appui contre la surface d'appui 9b de l'organe de butée dont la surface d'appui 9a est elle-même en appui contre la surface de butée 1 b du boîtier. Le pène est alors contraint d'osciller autour de son axe d'articulation de manière à s'escamoter et libérer la gâche. Une fois cet organe de butée franchi, l'extrémité correspondante du pène est alors libérée et le pène retourne dans sa position active d'accrochage sous l'action des moyens élastiques le sollicitant vers cette position. A cet effet, il y a lieu de noter que ce pène est sollicité élastiquement vers sa position active par un ressort 12 dont l'une des extrémités est en appui sur le coulisseau 10 et l'autre sur le pène 3.When the actuating means 7 are controlled so as to ensure a displacement of the bolt 3 from the locking position B to the hooking position A, the corresponding end of the bolt and more particularly the bearing surface 3a of the latter, bears against the bearing surface 9b of the abutment member, the bearing surface 9a of which itself is in abutment against the abutment surface 1b of the housing. The bolt is then forced to oscillate around its axis of articulation so as to retract and release the keeper. Once this stop member has been crossed, the corresponding end of the bolt is released and the bolt returns to its active hooking position under the action of elastic means urging it towards this position. To this end, it should be noted that this bolt is urged elastically towards its active position by a spring 12, one end of which bears on the slide 10 and the other on the bolt 3.

Les moyens d'actionnement 7 mentionnés précédemment, comportent par exemple un moto-réducteur 13 dont l'arbre de sortie coopère avec des moyens d'entrainement 14, constitué par exemple par un système 15 à roue et vis sans fin irréversible, reliés à une bande d'entraînement 16 montée déplaçable dans une glissière 17 solidiare du boîtier et dont l'une des extrémités est solidaire du coulisseau 10. Il est également à noter que le coulisseau 10 est monté déplaçable dans cette glissière 17.The actuation means 7 mentioned above, for example comprise a geared motor 13 whose output shaft cooperates with drive means 14, constituted for example by a system 15 with an irreversible wheel and worm gear, connected to a drive band 16 mounted movable in a solid slide 17 of the housing and one of the ends of which is integral with the slide 10. It should also be noted that the slide 10 is mounted movable in this slide 17.

Il va de soi que d'autres modes de réalisa tion sont possibles. Ainsi par exemple, la bande d'entraï- nement peut être supprimée dans le cas où on utilise un système d'entraînement par bielle-manivelle relié au coulisseau 10 et au moto-réducteur pour assurer le déplacement du pène. Ceci permet d'utiliser un moteur à un seul sens de rotation, ce que n'est pas le cas pour le système à bande décrit précédemment.It goes without saying that other embodiments are possible. Thus, for example, the drive band can be omitted in the case where a drive system is used by crank-rod connected to the slide 10 and to the gear motor to ensure the displacement of the bolt. This allows the use of a motor with only one direction of rotation, which is not the case for the belt system described above.

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

Lorsque l'utilisateur déplace la partie mobile du véhicule sur laquelle est fixée la gâche vers la position d'accrochage A, cette gâche 4 coopère avec la surface inclinée 6a des moyens d'accrochage 6 du pène 3 pour déplacer celui-ci vers sa position escamotée et permettre à la gâche de franchir les moyens d'accrochage et d'arriver dans la position d'accrochage A.When the user moves the movable part of the vehicle on which the keeper is fixed towards the hooking position A, this keeper 4 cooperates with the inclined surface 6a of the hooking means 6 of the bolt 3 to move the latter towards its position retracted and allow the keeper to pass through the hooking means and arrive in the hooking position A.

Dans cette position, les moyens de détection de la présence de la gâche en position d'accrochage alimentent le moto-réducteur 13 dans un certain sens pour que celui-ci entraîne un déplacement de la bande d'entraînement 16 et donc du coulisseau 10 et du pène 3 vers la position de verouillage 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 geared motor 13 in a certain direction so that it causes a displacement of the drive belt 16 and therefore of the slide 10 and from bolt 3 to the locking position B of the keeper by the bolt.

Lors de ce déplacement, l'extrémité correspondante du pène oblige l'organe du butée 9 à s'escamoter jusqu'à ce que l'extrémité ait franchi cet organe.During this movement, the corresponding end of the bolt forces the member of the stop 9 to retract until the end has crossed this member.

En position de verrouillage B de la gâche, l'alimentation du moto-réducteur est coupée par l'interrupteur de fin de course correspondant et l'extrémité correspondante du pène est alors disposée sous l'organe de butée, en appui contre la première surface de butée 1 a du boîtier, de qui empêche le pène de basculer, étant donné que le système à roue et vis sans fin irréversible bloque le coulisseau en position.In the lock position B of the keeper, the power supply to the gear motor is cut by the corresponding limit switch and the corresponding end of the bolt is then placed under the stop member, pressing against the first surface stopper 1a of the housing, which prevents the bolt from tilting, since the irreversible worm and wheel system blocks the slide in position.

Lorsque l'utilisateur désire déverrouiller la gâche, il actionne un interrupteur de déverrouillage qui alimente le moto-réducteur de manière que le coulisseau et donc le pène se déplacent vers la position d'accrochage A. Lors de ce déplacement, l'extrémité correspondante du pène vient en appui contre l'organe de butée, qui est lui-même en appui contre la seconde surface de butée 1 b du boîtier, ce qui oblige le pène à osciller vers sa position escamotée de libération de la gâche. Le déplacement du pène se poursuit tant que son extrémité correspondante n'a pas franchi totalement l'organe de butée et que l'interrupteur de fin de course détectant la présence du pène en position d'accrochage de la gâche, n'a pas été actionné. Lorsque celui-ci est actionné, il coupe l'alimentation du moto-réducteur de manière à arrêter le déplacement du pène qui est alors prêt pour un autre cycle de verrouillage.When the user wishes to unlock the keeper, he actuates an unlocking switch which supplies the gear motor so that the slide and therefore the bolt move to the hooking position A. During this movement, the corresponding end of the bolt abuts against the stop member, which itself is pressed against the second abutment surface 1b of the housing, which forces the bolt to oscillate towards its retracted position for release of the keeper. The movement of the bolt continues until its corresponding end has not completely crossed the stop member and the limit switch detecting the presence of the bolt in the position where the strike plate is hung has not been operated. When the latter is actuated, it cuts the power supply to the gear motor so as to stop the movement of the bolt which is then ready for another locking 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.

Ainsi, la serrure selon l'invention permet un verrouillage en douceur de la gâche, le pène assurant un verrouillage automatique de la gâche.Thus, the lock according to the invention allows a soft locking of the strike, the bolt ensuring an automatic locking of the strike.
