Abstract

The door release (10) has an actuating bar (46) that is mobile and switches supply to an electric motor (12) which operates the lock through a linkage (14). The actuator connects supply to the motor when the manual door release button (16) is moved to the open position. At the end of the lock release part of the operating linkage (24) displaces the actuating bar to interrupt the motor supply.

Description

L'invention concerne un dispositif motorisé perfectionné pour l'ouverture d'une serrure de véhicule automobile.The invention relates to a motorized device improved for opening a vehicle lock automobile.

L'invention concerne plus particulièrement un dispositif motorisé d'ouverture d'une serrure de véhicule automobile, du type comportant un organe de commande qui peut être amené par un utilisateur d'une position de repos à une position d'ouverture dans laquelle il commande l'alimentation d'un moteur électrique qui entraíne une tringlerie selon un cycle d'ouverture de la serrure.The invention relates more particularly to a motorized device for opening a vehicle lock automobile, of the type comprising a control member which can be brought by a user from a rest position to a open position in which it controls the supply of an electric motor which drives a linkage according to a lock opening cycle.

Dans un tel dispositif, il n'y a plus de liaison mécanique directe entre l'organe de commande, qui seul est accessible à l'utilisateur depuis l'extérieur du véhicule, et la serrure proprement dite qui maintient en position fermée un ouvrant du véhicule.In such a device, there is no longer a connection direct mechanics between the control unit, which alone is accessible to the user from outside the vehicle, and the lock proper which keeps a closed position opening the vehicle.

Par ailleurs, cette absence de liaison directe permet de se dispenser des systèmes de verrouillage classiques faisant par exemple appel à des verrous rotatifs à barillet. En effet, il est possible de soumettre la mise en marche du moteur, lorsque l'utilisateur manipule l'organe de commande, à la condition qu'une information de déverrouillage ait été précédemment transmise, par exemple par liaison radiofréquence, infrarouge ou ultrasonore, à une centrale antivol du véhicule. L'utilisateur est alors muni d'un badge, d'un transpondeur ou d'une télécommande grâce à laquelle il peut déterminer un état verrouillé ou déverrouillé du dispositif d'ouverture de la serrure.Furthermore, this absence of direct connection allows to dispense with conventional locking systems making for example using rotary barrel locks. Indeed, it is possible to submit the engine start-up, when the user manipulates the control unit, at the provided that unlock information has been previously transmitted, for example by radio frequency link, infrared or ultrasonic, to an anti-theft control unit in the vehicle. The user is then provided with a badge, a transponder or a remote control with which it can determine a state locked or unlocked the opening device of the lock.

Cependant, les dispositifs motorisés d'ouverture connus jusqu'à présent nécessitent la présence d'un circuit électronique de commande du moteur électrique relativement complexe. En effet, il faut habituellement détecter la position de l'organe de commande, gérer le démarrage du moteur, détecter une position d'ouverture de la tringlerie dans laquelle la serrure a libéré l'ouvrant, inverser le sens de rotation du moteur électrique pour ramener la serrure dans un état de fermeture et dètecter l'arrivée de la tringlerie dans cet état.However, the known motorized opening devices so far require the presence of an electronic circuit relatively complex electric motor control. In effect, you usually have to detect the position of the organ , manage engine start, detect a position opening of the linkage in which the lock released the sash, reverse the direction of rotation of the electric motor to return the lock to a closed state and detect the arrival of the linkage in this state.

Le circuit électronique de commande doit donc utiliser des capteurs de fin de course agencés judicieusement dans le dispositif et comporter des moyens de temporisation et d'inversion du sens du courant d'alimentation du moteur électrique.The electronic control circuit must therefore use limit switches sensibly arranged in the device and include timing means and reversing the direction of the motor supply current electric.

L'invention a donc pour objet de proposer un dispositif motorisé d'ouverture qui permet notamment de simplifier au maximum le circuit électronique de commande du véhicule.The object of the invention is therefore to propose a device motorized opening which allows in particular to simplify the maximum electronic control circuit of the vehicle.

Dans ce but, l'invention propose un dispositif motorisé d'ouverture d'une serrure de véhicule automobile, du type comportant un organe de commande qui peut être amené par un utilisateur d'une position de repos à une position d'ouverture dans laquelle il commande l'alimentation d'un moteur électrique qui entraíne une tringlerie selon un cycle d'ouverture de la serrure, le dispositif d'ouverture comportant un actionneur qui est mobile entre une position d'alimentation, dans laquelle le moteur est alimenté électriquement, et une position de coupure dans laquelle l'alimentation du moteur est coupée, l'actionneur étant amené de sa position de coupure à sa position d'alimentation par l'organe de commande lorsque ce dernier est amené par l'utilisateur de sa position de repos à sa position d'ouverture et, en fin de cycle d'ouverture de la serrure, la tringlerie ramène l'actionneur vers sa position de coupure, caractérisé en ce que l'actionneur est porté par l'organe de commande sur lequel il est mobile entre une position relative avancée, qu'il occupe lorsque l'actionneur et l'organe de commande sont simultanément dans leur position respectivement de coupure et de repos ou simultanément dans leur position d'alimentation et d'ouverture, et une position relative reculée qu'il occupe lorsque l'organe de commande est en position d'ouverture et que l'actionneur est ramené en position de coupure.To this end, the invention provides a motorized device opening a motor vehicle lock, of the type comprising a control member which can be brought by a user from a rest position to an open position in which it controls the supply of an electric motor which leads to a linkage according to an opening cycle of the lock, the opening device comprising an actuator which is movable between a feeding position, in which the motor is electrically powered, and a cut-off position in which the motor supply is cut off, the actuator being brought from its cut-off position to its position supply by the control unit when the latter is brought by the user from its rest position to its position opening and, at the end of the lock opening cycle, the linkage brings the actuator back to its cut-off position, characterized in that the actuator is carried by the control on which it is movable between a relative position advanced, which it occupies when the actuator and the control are simultaneously in their respective positions of cut off and rest or simultaneously in their position supply and opening, and a relative position moved away that it occupies when the control member is in position the actuator is returned to the position break.

Le dispositif 10 qui est illustré sur les figures est destiné à assurer l'ouverture d'une serrure (non représentée) qui maintient en position fermée un ouvrant de véhicule automobile.The device 10 which is illustrated in the figures is intended to ensure the opening of a lock (not shown) which keeps a vehicle leaf in the closed position automobile.

Le dispositif 10 est motorisé en ce qu'il comporte un moteur électrique 12 qui, lorsqu'il est alimenté, provoque le passage d'une tringlerie de commande 14 de la serrure d'un état de fermeture à un etat d'ouverture dans lequel la serrure libère l'ouvrant qui peut être alors ouvert.The device 10 is motorized in that it comprises a electric motor 12 which, when powered, causes the passage of a control linkage 14 of the lock of a state closing in an opening state in which the lock releases the opening which can then be opened.

Le moteur électrique 12 commande aussi le retour de la tringlerie 14 vers un état initial de fermeture dans lequel la serrure est amenée dans un état dans lequel elle est susceptible de nouveau de maintenir l'ouvrant en position fermée.The electric motor 12 also controls the return of the linkage 14 to an initial closing state in which the lock is brought into a state in which it is susceptible again to keep the sash in the closed position.

Dans le dispositif 10, l'utilisateur provoque l'ouverture de la serrure en amenant un organe de commande, ici réalisé sous la forme d'un poussoir 16, d'une position longitudinale reculée de repos, illustrée par exemple aux figures 2 et 3, à une position longitudinale avancée d'ouverture illustrée par exemple aux figures 5 et 6. Le poussoir 16 est donc monté coulissant selon un axe longitudinal A1 dans un boítier 18 qui est illustré plus particulièrement à la figure 2 et qui est destiné à être fixé sur un élément de carrosserie du véhicule de telle manière que le poussoir 16 soit accessible depuis l'extérieur du véhicule.In device 10, the user causes the opening of the lock by bringing a control member, here produced in the form of a pusher 16, from a position longitudinal retracted from rest, illustrated for example in Figures 2 and 3, in an advanced longitudinal opening position illustrated for example in Figures 5 and 6. The pusher 16 is therefore slidably mounted along a longitudinal axis A1 in a box 18 which is illustrated more particularly in Figure 2 and which is intended to be fixed to a body element of the vehicle in such a way that the pusher 16 is accessible from outside the vehicle.

La tringlerie 14, qui est agencée longitudinalement en avant d'une paroi transversale avant 20 du boítier 18, comporte essentiellement une roue de commande 22, un levier de renvoi 24 et une tringle de liaison 26.The linkage 14, which is arranged longitudinally in front of a front transverse wall 20 of the housing 18, comprises essentially a control wheel 22, a return lever 24 and a connecting rod 26.

La roue 22 est montée à rotation autour de son axe longitudinal A2, parallèle à l'axe A1 de coulissement du poussoir 16, et elle est susceptible d'être entraínée en rotation par le moteur électrique 12 dont l'arbre moteur, d'axe A3 parallèle à l'axe A2, porte un pignon 28 qui engrène avec une surface cylindrique externe dentée 30 de la roue 22.The wheel 22 is rotatably mounted about its axis longitudinal A2, parallel to the sliding axis A1 of the pusher 16, and it is likely to be driven in rotation by the electric motor 12 including the motor shaft, of axis A3 parallel to axis A2, carries a pinion 28 which meshes with a external cylindrical toothed surface 30 of the wheel 22.

Le levier de renvoi 24 est monté pivotant autour d'un axe A4, parallèle aux axes A2 et A3 de la roue 22 et du moteur 12, dans un plan agencé longitudinalement en arrière de la roue 22 mais en avant de la paroi transversale avant 20 du boítier 18. The return lever 24 is pivotally mounted around a axis A4, parallel to axes A2 and A3 of wheel 22 and of the motor 12, in a plane arranged longitudinally behind the wheel 22 but in front of the front transverse wall 20 of the housing 18.

Le levier 24 comporte un doigt de palpage 32 qui est destiné à coopérer avec une came 34 qui est agencée en relief sur une surface transversale arrière 36 de la roue 22. Comme on peut le voir plus particulièrement sur les figures 15 et 16, la came 34 comporte une surface latérale 38 qui est excentrée par rapport à l'axe A2 de rotation de la roue et le levier 24 est sollicité en rotation autour de son axe A4 par des moyens élastiques (non représentés) de telle manière que son doigt de palpage 32 soit en appui, radialement par rapport à l'axe A2, contre la surface latérale 38 de la came 34. De la sorte, lorsque la roue 22 est entraínée en rotation autour de son axe A2, le doigt de palpage 32 suit le profil de la surface de came 38 qui tourne avec la roue 22 et, en fonction de ce profil, provoque la rotation du levier de renvoi 24 autour de son axe A4.The lever 24 includes a feeler finger 32 which is intended to cooperate with a cam 34 which is arranged in relief on a rear transverse surface 36 of the wheel 22. As is can be seen more particularly in FIGS. 15 and 16, the cam 34 has a lateral surface 38 which is offset by relative to the axis A2 of rotation of the wheel and the lever 24 is rotated around its axis A4 by means elastic (not shown) so that his finger probing 32 is in abutment, radially with respect to the axis A2, against the lateral surface 38 of the cam 34. In this way, when the wheel 22 is rotated about its axis A2, the probing finger 32 follows the profile of the cam surface 38 which rotates with the wheel 22 and, according to this profile, causes the return lever 24 to rotate about its axis A4.

La tringle 26 est reliée par une de ses extrémités 40 en rotation autour d'un axe A5, parallèle aux axes A4 et A2, au levier 24 si bien que, lorsque celui-ci pivote autour de son axe A4, la tringle 26 est animée sensiblement d'un mouvement de translation selon sa direction d'allongement. L'autre extrémité (non représentée) de la tringle 26 étant reliée à la serrure de l'ouvrant, le dispositif 10 est ainsi susceptible de commander l'ouverture de la serrure grâce à la tringlerie 14.Rod 26 is connected by one of its ends 40 rotating around an axis A5, parallel to axes A4 and A2, at lever 24 so that when it pivots about its axis A4, the rod 26 is driven substantially by a movement of translation according to its direction of elongation. The other extremity (not shown) of the rod 26 being connected to the lock of opening it, the device 10 is thus capable of controlling the opening of the lock thanks to the linkage 14.

Comme on peut le voir sur la figure 1, le moteur électrique 12 et la roue 22 sont destinés à être reçus dans un carter avant 42 fixé en avant du boítier 18.As can be seen in Figure 1, the motor electric 12 and the wheel 22 are intended to be received in a front housing 42 fixed in front of the housing 18.

Comme on peut le voir sur les figures 15 et 16, le profil de la surface de came 38 de la came 34 est tel qu'un cycle d'ouverture de la tringlerie de commande 14 de la serrure, qui comporte le passage d'un état de fermeture à un état d'ouverture et - un retour à l'état de fermeture initial, correspond à un tour complet de la roue 22.As can be seen in Figures 15 and 16, the profile of the cam surface 38 of the cam 34 is such that a opening cycle of the control linkage 14 of the lock, which involves the transition from a closed state to a state opening and - a return to the initial closing state, corresponds to one complete revolution of wheel 22.

Ainsi, selon une première caractéristique de l'invention, le moteur électrique 12 est commandé toujours dans le même sens de rotation puisque, après un tour complet de la roue 22, le doigt de palpage 32 se retrouve en appui contre une portion de la surface de commande 38 qui correspond à l'état de fermeture de la serrure; après avoir parcouru l'intégralité du profil de la surface 38 qui provoque son passage par une position d'ouverture illustrée à la figure 16.Thus, according to a first characteristic of the invention, the electric motor 12 is always controlled in the same direction of rotation since, after a full revolution of the wheel 22, the feeler finger 32 finds itself in abutment against a portion of the control surface 38 which corresponds to the state of closing the lock; after going through the entire profile of the surface 38 which causes it to pass through a open position illustrated in Figure 16.

Par ailleurs, l'alimentation électrique du moteur électrique 12 est commandée par un interrupteur 44 qui, lorsqu'il est dans un état ouvert, interrompt l'alimentation du moteur 12 qui reste alors à l'arrêt, et qui, dans un état fermé, permet le passage du courant dans le circuit d'alimentation du moteur 12, lequel provoque alors la rotation du pignon de commande 28 et donc de la roue 22.In addition, the power supply to the motor electric 12 is controlled by a switch 44 which, when in an open state, interrupts power to the motor 12 which then remains stopped, and which, in a closed state, allows current to flow through the supply circuit of the motor 12, which then causes the pinion to rotate control 28 and therefore of the wheel 22.

Bien entendu, le circuit d'alimentation du moteur 12 comportera de préférence un deuxième interrupteur qui sera commandé par exemple par une centrale électronique d'antivol en fonction d'une information de verrouillage ou de déverrouillage fournie à la centrale par l'utilisateur au moyen par exemple d'une télécommande. Ainsi, le moteur électrique 12 ne sera alimenté en courant que si les deux interrupteurs, par exemple agencés en série dans le circuit d'alimentation, sont simultanément dans leur état fermé correspondant à un ordre préalable de déverrouillage puis à un ordre d'ouverture de la serrure.Of course, the power circuit of the motor 12 preferably include a second switch which will controlled for example by an electronic anti-theft control unit in function of locking or unlocking information supplied to the control panel by the user, for example a remote control. Thus, the electric motor 12 will only supplied with current only if the two switches for example arranged in series in the supply circuit, are simultaneously in their closed state corresponding to an order prior to unlocking and then to an order to open the lock.

Selon un autre aspect de l'invention, le poussoir 16 n'agit pas directement sur l'interrupteur 44, mais par l'intermédiaire d'un actionneur 46. L'actionneur 46 comporte essentiellement un corps principal allongé selon la direction longitudinale A1 de coulissement du poussoir 16 et il est mobile en coulissement selon cette direction entre une position longitudinale reculée de coupure et une position longitudinale avancée d'alimentation dans laquelle il coopère par une extrémité longitudinale avant 48 avec l'interrupteur 44 pour amener celui-ci à son état fermé dans lequel il est susceptible d'alimenter le moteur électrique 12 en courant. Par son extrémité longitudinale arrière 50, qui est reçue à l'intérieur du boítier 18, en arrière de la paroi transversale avant 20 de celui-ci, l'actionneur 46 est monté coulissant selon la direction longitudinale A1 dans le poussoir 16.According to another aspect of the invention, the pusher 16 does not act directly on switch 44, but by via an actuator 46. The actuator 46 comprises essentially a main body elongated in the direction longitudinal A1 for sliding the pusher 16 and it is movable sliding in this direction between a position longitudinal cut-off and a longitudinal position feed forward in which it cooperates by a front longitudinal end 48 with switch 44 for bring it to its closed state in which it is susceptible to supply the electric motor 12 with current. By its rear longitudinal end 50, which is received inside of the housing 18, behind the front transverse wall 20 of this one, the actuator 46 is slidably mounted according to the longitudinal direction A1 in pusher 16.

Par rapport au poussoir 16, l'actionneur 46 peut donc occuper une position relative avancée, lorsque l'actionneur 46 et l'organe de commande 16 sont simultanément et respectivement dans leur position de coupure ou de repos ou, simultanément dans leur position d'alimentation et d'ouverture. L'actionneur 46 peut aussi occuper, par rapport à l'organe de commande 16, une position relative reculée dans laquelle il se trouve lorsque l'organe de commande 16 est en position d'ouverture et que l'actionneur 46 est ramené en position de coupure.Compared to the pusher 16, the actuator 46 can therefore occupy an advanced relative position, when the actuator 46 and the control member 16 are simultaneously and respectively in their cut-off or rest position or, simultaneously in their feeding and opening position. The actuator 46 can also occupy, with respect to the control member 16, a relative relative position in which it is located when the control member 16 is in the open position and that the actuator 46 is returned to the cut-off position.

Des moyens élastiques bistables sont interposés entre l'actionneur 46 et le poussoir 16 pour solliciter l'actionneur 46 vers l'une ou vers l'autre de ces deux positions relatives par rapport au poussoir 16.Bistable elastic means are interposed between the actuator 46 and the pusher 16 to urge the actuator 46 towards one or the other of these two relative positions relative to pusher 16.

Ainsi, le dispositif 10 comporte une épingle 52 à deux branches 54, 56 repliée en U. Les deux branches 54, 56 s'étendent sensiblement parallèlement selon une direction transversale perpendiculaire à la direction de coulissement A1 du poussoir 16 et de l'actionneur 46. Une première des branches 54 est engagée dans un orifice 58 correspondant aménagé dans le poussoir 16 de telle manière que l'épingle 52 n'a pas d'autres possibilités que de pivoter autour de cette première branche 54 par rapport à l'organe de commande 16. La seconde branche 56 est reçue à la fois dans un orifice correspondant 60 aménagé dans l'actionneur 46 et dans une fenêtre longitudinale 62 aménagée dans le poussoir 16. Ainsi, comme on peut le voir plus particulièrement sur les figures 4 et 14, la course de l'actionneur 46 par rapport au poussoir 16 est limitée par l'arrivée en butée de la seconde branche 56 de l'épingle 42 contre l'une des extrémités longitudinales avant 64 et arrière 66 de la fenêtre 62 du poussoir 16.Thus, the device 10 comprises a pin 52 with two branches 54, 56 folded in a U. The two branches 54, 56 extend substantially parallel in one direction transverse perpendicular to the direction of sliding A1 pusher 16 and actuator 46. A first of the branches 54 is engaged in a corresponding orifice 58 arranged in the pusher 16 so that the pin 52 has no other possibilities that to pivot around this first branch 54 relative to the control member 16. The second branch 56 is received at the same time in a corresponding orifice 60 arranged in the actuator 46 and in a longitudinal window 62 fitted in pusher 16. So, as we can see more particularly in Figures 4 and 14, the travel of the actuator 46 relative to the pusher 16 is limited by the arrival in abutment of the second branch 56 of the pin 42 against one of the front longitudinal ends 64 and rear 66 of window 62 of pusher 16.

Par ailleurs, lorsque l'actionneur 46 se déplace par rapport au poussoir 16, il provoque donc une rotation de l'épingle 52 autour de sa première branche 54, mais il provoque aussi une déformation élastique de cette épingle 52 par rapprochement de ses deux branches 54, 56.Furthermore, when the actuator 46 moves by compared to pusher 16, it therefore causes a rotation of the pin 52 around its first branch 54, but it causes also an elastic deformation of this pin 52 by bringing together its two branches 54, 56.

Comme on peut le voir sur les figures, l'orifice 58 dans lequel est engagée la première branche 54 est agencé longitudinalement sensiblement au même niveau que le milieu de la fenêtre 62 dans laquelle se déplace la seconde branche 56. De la sorte, lorsque la seconde branche 56 est longitudinalement au milieu de la fenêtre 62, l'épingle 52 est dans son état de déformation maximale si bien que le système constitué du poussoir 16 de l'épingle 52 et de l'actionneur 46 est alors dans une position d'équilibre instable, l'épingle 52 ayant alors tendance, en se détendant, à provoquer le déplacement de l'actionneur 46 vers l'une ou l'autre de ses positions relatives avancée ou reculée par rapport au poussoir 16.As can be seen in the figures, the orifice 58 in which is engaged the first branch 54 is arranged longitudinally substantially at the same level as the middle of the window 62 in which the second branch 56 moves. so, when the second branch 56 is longitudinally at middle of window 62, pin 52 is in its state of maximum deformation so that the system consisting of pusher 16 of pin 52 and actuator 46 is then in an unstable equilibrium position, the pin 52 then having tendency, by relaxing, to cause the displacement of actuator 46 to either of its relative positions forward or backward relative to pusher 16.

Selon encore un autre aspect de l'invention, l'actionneur 16 comporte deux bras transversaux avant 68 et arrière 70 qui sont destinés à coopérer avec la roue 22. Le bras transversal avant 68 s'étend dans un plan transversal qui est agencé longitudinalement en avant d'une face transversale avant 72 de la roue 22. Comme on peut le voir par exemple sur les figures 2 à 4, la roue 22 comporte, sur cette face transversale avant 72, une collerette 74 d'axe A2 qui est aménagée en relief sur la face 72 et qui est pourvue d'une encoche 76.According to yet another aspect of the invention, the actuator 16 has two front transverse arms 68 and rear 70 which are intended to cooperate with the wheel 22. The arm transverse before 68 extends in a transverse plane which is arranged longitudinally in front of a front transverse face 72 of wheel 22. As can be seen for example on the Figures 2 to 4, the wheel 22 has, on this transverse face before 72, a flange 74 of axis A2 which is arranged in relief on the face 72 and which is provided with a notch 76.

En fonction de la position angulaire de la roue 22, le bras transversal avant 68 est agencé longitudinalement en regard soit de la collerette 74, soit de l'encoche 76. La collerette 74 présente une épaisseur longitudinale telle que, lorsque le bras 68 est en regard de la collerette, l'actionneur 46 ne peut être ramené vers l'arrière vers sa position de coupure. Il ne peut être ramené vers cette position que lorsqu'il est en regard de l'encoche 76 aménagée dans la collerette 74.Depending on the angular position of the wheel 22, the front transverse arm 68 is arranged longitudinally opposite either from the collar 74, or from the notch 76. The collar 74 has a longitudinal thickness such that, when the arm 68 is facing the flange, the actuator 46 cannot be brought back towards its cut position. He can not be brought back to this position only when it is next to the notch 76 fitted in the collar 74.

Par ailleurs, lorsque l'actionneur 46 est en position reculée de coupure, le bras transversal avant 68 est engagé dans l'encoche 76 de la collerette 74 et le bras 68 empêche ainsi la roue 74 de pouvoir pivoter autour de son axe A2 en venant en appui contre les bords de l'encoche.Furthermore, when the actuator 46 is in position cut back, the front transverse arm 68 is engaged in the notch 76 of the collar 74 and the arm 68 thus prevents the wheel 74 to be able to pivot around its axis A2 coming in press against the edges of the notch.

Le bras arrière 70 de l'actionneur 46 s'étend dans un plan transversal qui est agencé en arrière de la face transversale arrière 36 de la roue 22. Le bras arrière 70 comporte un tronçon transversal à l'extrémité libre duquel est agencé un tronçon longitudinal 78 qui s'étend vers l'avant.The rear arm 70 of the actuator 46 extends in a transverse plane which is arranged behind the face rear transverse 36 of the wheel 22. The rear arm 70 has a transverse section at the free end of which is arranged a longitudinal section 78 which extends forward.

Comme on peut le voir par exemple sur la figure 1, la face transversale arrière 36 de la roue 22 comporte une gorge périphérique annulaire 80 d'axe A2 qui est aménagée en creux. Lorsque l'actionneur 46 est en position avancée d'alimentation, le tronçon longitudinal 78 du bras arrière 70 est engagé dans la gorge 80. Par ailleurs, la roue 22 comporte une rampe 82 qui est aménagée dans la gorge 80 et qui est destinée à coopérer avec le tronçon longitudinal 78 du bras arrière 70 pour provoquer le recul de l'actionneur 46 vers sa position reculée de coupure lorsque la rampe 82 de la roue 22 arrive en coïncidence avec le bras arrière 70As can be seen for example in Figure 1, the rear transverse face 36 of the wheel 22 has a groove annular device 80 of axis A2 which is hollowed out. When the actuator 46 is in the advanced feed position, the longitudinal section 78 of the rear arm 70 is engaged in the groove 80. Furthermore, the wheel 22 has a ramp 82 which is arranged in the groove 80 and which is intended to cooperate with the longitudinal section 78 of the rear arm 70 to cause the retraction of the actuator 46 to its retracted cut-off position when the ramp 82 of the wheel 22 arrives in coincidence with the rear arm 70

Le fonctionnement du dispositif 10 selon l'invention va maintenant être décrit plus particulièrement en regard des figures 2 à 12.The operation of the device 10 according to the invention will now be described more particularly with regard to Figures 2 to 12.

Lorsque le dispositif 10 est en position de repos illustrée sur les figures 2 à 4, le poussoir 16 et l'actionneur 46 sont tous les deux dans leur position reculée, respectivement de repos et de coupure. L'actionneur 46 est alors en position relative avancée par rapport au poussoir 16 comme le montre la figure 4 dans laquelle on peut voir que la seconde branche 56 de l'épingle 52 est en appui contre l'extrémité longitudinale avant 64 de la fenêtre 62.When the device 10 is in the rest position illustrated in FIGS. 2 to 4, the pusher 16 and the actuator 46 are both in their remote position, respectively rest and break. The actuator 46 is then in position relative advanced compared to pusher 16 as shown in the Figure 4 in which we can see that the second branch 56 of the pin 52 is in abutment against the front longitudinal end 64 of window 62.

On peut voir aussi que le bras transversal avant 68 est reçu dans l'encoche 76 de la collerette 74 de manière à bloquer la rotation de la roue 22. Enfin, on peut voir sur la figure 3 que l'extrémité avant 48 de l'actionneur 46 ne coopère pas avec l'interrupteur 44 qui est alors dans son état ouvert dans lequel le moteur électrique 12 n'est pas alimenté en courant.We can also see that the front transverse arm 68 is received in the notch 76 of the collar 74 so as to block the rotation of the wheel 22. Finally, we can see in Figure 3 that the front end 48 of the actuator 46 does not cooperate with the switch 44 which is then in its open state in which the electric motor 12 is not supplied with current.

A partir de cette position de repos, l'utilisateur peut, pour provoquer l'ouverture de la serrure, appuyer sur le poussoir 16 afin de l'amener vers sa position avancée d'ouverture ainsi que cela est représenté sur les figures 5 à 7. On remarque alors que, du fait de l'action de l'épingle 52 qui est dans une position d'équilibre stable, le poussoir 16 provoque le déplacement de l'actionneur 46 longitudinalement vers l'avant vers sa position d'alimentation dans laquelle, comme on peut le voir sur la figure 6, l'extrémité avant 48 de l'actionneur 46 provoque le passage de l'interrupteur 44 à son état fermé. L'actionneur 46 reste donc dans sa position relative avancée par rapport au poussoir 16.From this rest position, the user can, to cause the opening of the lock, press the pusher 16 in order to bring it to its advanced position as shown in Figures 5 to 7. We notice then that, due to the action of the pin 52 which is in a stable equilibrium position, the pusher 16 causes the actuator 46 to move longitudinally forward towards its feeding position in which, as can be seen in Figure 6, the front end 48 of the actuator 46 causes the switch 44 to pass to its closed state. The actuator 46 therefore remains in its relative position advanced relative to pusher 16.

A ce moment-là, comme on peut le voir notamment sur la figure 7, le bras transversal avant 68 est dégagé de l'encoche 76 tandis que le tronçon longitudinal 78 du bras arrière 70 est engagé dans la gorge 80.At that time, as can be seen in particular on the Figure 7, the front transverse arm 68 is released from the notch 76 while the longitudinal section 78 of the rear arm 70 is engaged in throat 80.

Le moteur électrique étant alimenté en courant et le bras transversal avant 68 étant dégagé de la fente 76, la roue 22 est donc entraínée en rotation autour de son axe A2.The electric motor being supplied with current and the front transverse arm 68 being released from slot 76, the wheel 22 is therefore rotated about its axis A2.

Il peut se produire alors deux types de situations. Dans une première situation, illustrée aux figures 8 et 9 l'utilisateur peut relâcher immédiatement le poussoir 16 et celui-ci, sollicité par un ressort de rappel 84, tend à être ramené vers sa position de repos. Cependant, l'actionneur 46 est alors en position avancée par rapport au poussoir 16 de sorte que l'épingle 52, dont la seconde branche 56, solidaire longitudinalement de l'actionneur 46, est en appui contre l'extrémité longitudinale avant 64 de la fenêtre 62 du poussoir 16, empêche que le poussoir 16 ne recule vers sa position de repos sans entraíner avec lui l'actionneur 46. Or, la roue 22 ayant commencé de pivoter autour de son axe A2 sous l'action du moteur 12, le bras transversal avant 68 de l'actionneur 46 est alors en regard de la collerette 74 et, sous l'effet du ressort de rappel 84, le bras transversal avant 68 est sollicité en appui longitudinalement vers l'arrière contre la collerette 74 qui empêche l'actionneur 46 de retourner vers sa position de coupure, empêchant par là même au poussoir 16 de retourner vers sa position de repos. Ainsi, même si l'utilisateur ne soumet le poussoir 16 qu'à une brève impulsion, une fois que le cycle d'ouverture de la serrure est entamé, il se poursuit jusqu'à sa fin. En effet, l'actionneur 46 étant maintenu par la collerette 74 en position d'alimentation, le moteur électrique 12 continue de faire tourner la roue 22 par l'intermédiaire du pignon de commande 28.Two types of situations can then occur. In a first situation, illustrated in Figures 8 and 9 the user can immediately release button 16 and this, biased by a return spring 84, tends to be returned to its rest position. However, the actuator 46 is then in the advanced position relative to the pusher 16 so that the pin 52, including the second branch 56, secured longitudinally of the actuator 46, is pressed against the front longitudinal end 64 of the window 62 of the pusher 16, prevents the pusher 16 from moving back to its position of rest without driving the actuator 46 with it. However, the wheel 22 having started to pivot around its axis A2 under the action of the motor 12, the front transverse arm 68 of the actuator 46 is then opposite the flange 74 and, under the effect of the spring 84, the front transverse arm 68 is stressed in longitudinally backwards against the flange 74 which prevents the actuator 46 from returning to its position of cut, thereby preventing the pusher 16 from returning to its rest position. So even if the user does not submit the push button 16 only at a short pulse, once the cycle opening of the lock is started, it continues until its end. Indeed, the actuator 46 being held by the flange 74 in the feed position, the electric motor 12 continues to rotate the wheel 22 via the pinion of command 28.

Bien entendu, si l'utilisateur maintient la pression sur le poussoir 16, le cycle d'ouverture se déroule normalement ainsi que cela est représenté aux figures 10 et 11.Of course, if the user maintains the pressure on push-button 16, the opening cycle proceeds normally as shown in Figures 10 and 11.

Dans le cas où l'utilisateur a relâché sa pression sur le poussoir 16, le poussoir 16 et l'actionneur 46 vont pouvoir regagner leur position respective de repos et de coupure dès que la roue aura effectué un tour complet de telle manière que la fente 76 se présente de nouveau en regard du bras transversal avant 68 de l'actionneur 46. L'ensemble du poussoir 16 et de l'actionneur 46 peut alors reculer sous l'action combinée du ressort de rappel .84 et de la rampe 82 qui, lorsqu'elle arrive au contact du tronçon longitudinal 78 du bras arrière 72, tend à repousser l'actionneur 46 vers l'arrière.In case the user has released his pressure on pusher 16, pusher 16 and actuator 46 will be able to regain their respective rest and cut-off positions as soon as the wheel will have made a full revolution in such a way that the slot 76 again presents itself opposite the transverse arm front 68 of actuator 46. The assembly of pusher 16 and the actuator 46 can then move back under the combined action of the return spring .84 and ramp 82 which, when it arrives in contact with the longitudinal section 78 of the rear arm 72, tends to push the actuator 46 backwards.

Dès que l'actionneur 46 a regagné sa position de coupure, le moteur électrique 12 n'est plus alimenté en courant et il s'arrête de tourner. Le dispositif 10 a alors regagné son état de repos et il est directement prêt à effectuer une nouvelle opération d'ouverture de la serrure.As soon as the actuator 46 has returned to its position disconnection, the electric motor 12 is no longer supplied with current and it stops spinning. The device 10 then regained its state of rest and it is directly ready to perform a new operation to open the lock.

Selon un autre aspect de l'invention, il est résolu le problème de pouvoir arrêter le moteur électrique 12 en fin de cycle d'ouverture même si l'utilisateur maintient le poussoir 16 enfoncé en position d'ouverture.According to another aspect of the invention, it is resolved on problem of being able to stop the electric motor 12 at the end of opening cycle even if the user maintains the button 16 pressed in the open position.

En effet, comme on peut le voir plus particulièrement sur les figures 12 à 14, en fin de cycle d'ouverture, la rampe 82 tend à repousser l'actionneur 46 vers l'arrière. Si le poussoir 16 est maintenu enfoncé, l'actionneur 46 va pouvoir malgré tout reculer vers sa position de coupure en se déplaçant relativement par rapport au poussoir 16 vers sa position axiale reculée. En effet, l'orifice 58 de l'actionneur 46 entraíne alors la seconde branche 56 de l'épingle 52, longitudinalement vers l'arrière, dans la fenêtre 62 du poussoir 16. Dans un premier temps, ce recul de l'actionneur 46 va provoquer un rapprochement des deux branches 54, 56 de l'épingle 52, jusqu'à la position d'équilibre instable décrite plus haut, puis l'épingle 52 va tendre à participer elle aussi au recul de l'actionneur 46 jusqu'à ce que sa seconde branche 56 vienne en appui contre l'extrémité longitudinale arrière 66 de la fenêtre 62. Par rapport au poussoir 16, l'actionneur 46 est alors dans sa position relative reculée et, par rapport au dispositif 10, il est dans sa position de coupure dans laquelle l'alimentation électrique du moteur 12 est interrompue provoquant l'arrêt de la rotation de la roue 22.Indeed, as we can see more particularly in Figures 12 to 14, at the end of the opening cycle, the ramp 82 tends to push the actuator 46 backwards. If the pusher 16 is held down, actuator 46 will be able to despite everything back to its cut position by moving relatively relative to the pusher 16 towards its axial position steephead Valley. Indeed, the orifice 58 of the actuator 46 drives then the second branch 56 of the pin 52, longitudinally backwards, in window 62 of pusher 16. In a first, this retraction of the actuator 46 will cause a bringing together the two branches 54, 56 of the pin 52, until the unstable equilibrium position described above, then the pin 52 will tend to participate also in the decline of the actuator 46 until its second branch 56 comes in support against the rear longitudinal end 66 of the window 62. With respect to the pusher 16, the actuator 46 is then in its relative position moved back and, relative to the device 10, it is in its cut-off position in which the power supply the electric motor 12 is interrupted causing the stop of the wheel rotation 22.

On notera d'ailleurs que, tant que l'utilisateur maintient le poussoir 16 enfoncé, rien ne se passe. Au contraire, dès que l'utilisateur relâche le poussoir 16, le ressort de compression 84 repousse ce dernier vers sa position de repos et il se produit alors un basculement de l'épingle 52, l'actionneur 46 ne pouvant reculer plus loin que sa position de coupure notamment du fait que son bras transversal avant 68 vient en appui contre la face transversale avant 72 de la roue 22.Note also that, as long as the user keeps push button 16 pressed, nothing happens. At on the contrary, as soon as the user releases the pusher 16, the compression spring 84 pushes the latter back to its position of rest and there then occurs a tilting of the pin 52, the actuator 46 cannot move back further than its position of cut in particular of the fact that its front transverse arm 68 abuts against the front transverse face 72 of the wheel 22.

Dès que le poussoir 16 a atteint sa position de repos, l'actionneur 46 se retrouve alors dans sa position relative avancée par rapport au poussoir 16 et le dispositif est de nouveau prêt à provoquer une nouvelle ouverture de la serrure.As soon as the pusher 16 has reached its rest position, the actuator 46 then finds itself in its relative position advanced relative to pusher 16 and the device is again ready to cause the lock to open again.

Il a été vu que, dans le mode de réalisation de l'invention qui vient d'être décrit, un cycle complet d'ouverture et de fermeture de la serrure correspond à un tour complet de la roue 22. Cependant, on peut aussi prévoir qu'un cycle complet ne corresponde qu'à une fraction de la rotation de la roue 22, par exemple un demi-tour. Dans ce cas, il est nécessaire que la roue 22 comporte une came adaptée, qui sera en l'occurrence symétrique autour de l'axe A2, ainsi que deux encoches et deux rampes 82 diamétralement opposées.It has been seen that in the embodiment of the invention which has just been described, a complete cycle opening and closing of the lock corresponds to one turn complete of wheel 22. However, one can also provide that a complete cycle only corresponds to a fraction of the rotation of the wheel 22, for example a U-turn. In this case, it is wheel 22 must have a suitable cam, which will be the symmetric occurrence around the axis A2, as well as two notches and two diametrically opposite ramps 82.

Dans tous les cas, le dispositif selon l'invention permet de simplifier considérablement le circuit de commande du moteur électrique. Il n'y a en effet pas à prévoir la prise en compte d'informations en provenance de capteurs de fin de course. Il n'y a pas non plus à prévoir de temporisation de fonctionnement du moteur ou de dispositif d'inversion du courant d'alimentation.In all cases, the device according to the invention considerably simplifies the control circuit of the electric motor. There is indeed no provision for taking account of information from end-of-life sensors race. There is also no provision for a time delay operation of the motor or current reversing device feed.

Le dispositif 10 selon l'invention se révèle simple et économique à mettre en oeuvre, tout en assurant les mêmes fonctions que les dispositifs de l'art antérieur.The device 10 according to the invention proves to be simple and economical to implement, while ensuring the same functions than the devices of the prior art.
