Definitions
- the present invention relates to locks for motor vehicle and, more particularly, locks with electric lock.
- Such locks comprise, in a known manner, a latch fork intended to cooperate with a keeper, a pawl ensuring normally locking the bolt in the closed position, a locking mechanism release of the bolt comprising a control member undergoing a actuation movement in response to actuation, by the user, from the door handle.
- the controller can take an active position for which he acts, during his actuation movement, on the pawl to put it in position escapement, and an inhibited position for which, during its movement actuation, it has no effect on the ratchet.
- the lock has, in in addition, an electrical device responding at least to a signal unlocking by moving the control member until it is reached from its active position.
- this unlocking signal is generated by actuation of a lock cylinder.
- this unlocking signal is provided by electronic recognition in response to an infrared remote control signal or of radio remote control produced by the user by means of a suitable remote control.
- the present invention therefore relates to a lock for motor vehicle door, comprising: a fork bolt intended for cooperate with a striker; a ratchet normally ensuring blocking of the bolt in the closed position and can take an "escaped" position for which it no longer acts on said bolt; a release mechanism of the bolt comprising a control member, which, on the one hand, can take either an active position for which he acts, during his actuation movement, on the pawl to put it in position "breakaway” is an inhibited position for which, when actuation movement, it has no effect on the ratchet and, on the other hand, may be actuated in response to user actuation of the door handle; and a device electric responding at least to an unlocking signal in moving the control member from its inhibited position to reaching its active position, characterized in that the organ of control consists of a set of two articulated links between them by a kneepad, one of the rods, said first connecting rod, has a pushing surface which is positioned in such a way so that
- the lever conviction / unlocking has a fork at one end between the branches of which the axis of the toggle to allow actuation movement of the organ both in its inhibited position and in its active position.
- the lock comprises a opening catch-up means which, when the signal is emitted unlocking substantially at the end of the movement actuation of the control member, brings the pawl into position breakaway, the opening take-up means being carried out in the manner next: part of the thrust surface and the adjacent part of the perimeter surface of the pawl being shaped and positioned so as to form respectively a fulcrum and a pivot cooperating with each other when the control member substantially in the end position of actuation movement, the movement of the control member by the lever locking / unlocking up to the active driving position, thanks to the action of the fulcrum on the pivot, the pawl of the pawl up to put said pawl in the escaped position.
- the opening of the door is obtained by a single actuation of the door handle, and this despite the difference between the response time of the mechanism release, very fast, and that of the electrical device unlocking, slower.
- the device electric has an electric motor to drive a mechanism of transmission of the movement which acts on the end, opposite to the end cooperating with the toggle joint, of the lever locking / unlocking, this lever being articulated on a fixed axis of the lock at an eccentric point on the side opposite the end cooperating with the knee lever, to increase the lever arm on the side knee brace.
- the two rods of the control member are substantially aligned in direction of the pawl, and the locking lever / unlocking cooperates with the kneepad so as to allow its displacement in said direction, during actuation movement of the control unit.
- the first link is guided, during the actuation movement of the commands, both in its active position and in its inhibited position, to so as to maintain the thrust surface substantially in the direction of the pawl pin.
- the first link is guided, during the actuating movement of the control member, both in its active position than in its inhibited position, so that keep the thrust surface in line with the pawl pin and the articulation between the second link and the opening lever exterior.
- the knee brace is a bistable joint having two stable angular positions corresponding to inhibited and active positions of the control member.
- the signal unlocking is issued by recognition electronics which is electrically powered only during the action exerted on the door handle by the user, said electronics then identifying a user authorized by a radio emission exchanged according to a appropriate protocol with an electronic element carried by the user ; this avoids unnecessary consumption of electrical energy.
- recognition electronics which is electrically powered only during the action exerted on the door handle by the user, said electronics then identifying a user authorized by a radio emission exchanged according to a appropriate protocol with an electronic element carried by the user ; this avoids unnecessary consumption of electrical energy.
- This can be achieved by a microswitch (or any other system normally open, closing of which is ordered by the opening action on the door handle, this system of control closing a power supply circuit of recognition electronics.
- the lock represented in FIGS. 1 to 3 comprises a box (not shown), a fork bolt 1 hinged in 2 on the housing, and a pawl 3 hinged in 4 on the housing.
- the bolt 1 is intended to cooperate, in a known manner, with a keep not shown.
- the pawl 3, in a known manner, is associated with elastic means not shown urging it towards a position ensuring the locking of the bolt 1 in the closed position, such that shown in Figures 1 and 3, and can be set to the "escaped" position against said elastic means, by a release mechanism bolt, controlled by a door handle (or pallet), not represented.
- the bolt release mechanism includes a lever actuation 5, also called external opening lever, articulated in 6 on the housing, a link 7 articulated by its end lower at 8 on the left end of lever 5, and by its end upper at 10 on the lower end of another link 11.
- the articulation axis 10 constitutes a movable hinge between the two links 7 and 11 which together form a control member to toggle for the pawl 3.
- the two links 7 and 11 extend in a substantially vertical direction in FIGS. 1 and 2.
- the lever 5 is articulated by its right end at 12 to one opening rod not shown which is connected to a handle of door.
- the lever 5 is associated with elastic means urging it towards its rest position in which it has been represented in FIG. 1.
- the lever 5 is intended to abut against a projection 13 provided on the lock box, to limit the pivoting of the lever 5, in its actuating stroke of the control member.
- the axis of articulation of the toggle joint 10 is housed at sliding between the branches of a fork 14, shown schematically and only in FIG. 3, forming part of a electric device for locking / unlocking the lock.
- the fork 14 is provided at one end of a lever 15 which is articulated at 16 on a fixed axis on the housing B and which comprises at its end opposite another fork 17 between the branches of which is received a pin 18 projecting from a nut 19.
- the nut 19 is suitable for translate longitudinally on a worm 20, when rotational drive, said screw 20 being integral in rotation with a toothed wheel 21 which meshes tangentially with a pinion gear 22 which is driven in turn by the motor shaft 23 of a electric motor 24.
- the lever locking / unlocking 15 can take two fixed positions per report to the lock box.
- a so-called condemned position for the lever 15 is shown in Figure 3 and corresponds to a position so-called inhibited angularity of the toggle 10 and therefore of the ordered.
- the other so-called unlocking position of the lever 15 is not shown, but corresponds to the so-called active angular position of the toggle switch 10 and therefore of the control member, shown in the Figures 1 and 2.
- the motor 24 of the electric actuator is designed to respond to a condemnation signal and a signal of unlocking, axially translating the nut 19 on the screw without end 20, so as to move the lever 15 around its axis 16 between its locking position (and therefore the knee lifter 10 in its inhibited position), and in its unlocked position (and consequently, the knee switch 10 in its active position).
- the unlocking signal can be issued by a recognition electronics, not shown, forming part of a system known per se "hands-free vehicle access” not requiring not use a key or remote control to unlock the lock.
- the recognition electronics are equipped of a radio transmitter and is designed to be able to communicate with a radio device incorporated into a watch, or card, or a badge, worn by the user.
- Recognition electronics don't produces its unlocking signal only after identification of the correct owner.
- the link 11 has at its upper end a thrust surface 11a substantially planar and perpendicular to the vertical direction in Figures 1 and 2.
- the pawl 3 has on its face turned towards the link 11 a pin 25 projecting in the direction of said link 11.
- the lever 5 In the position illustrated in FIG. 3, the lever 5 is in actuated position, and the knee switch control unit retains substantially the angled shape which is visible in phantom on the FIG. 1.
- the joint 8 lifts and moves the link 7 upwards, and by next, the toggle 10, because the axis of the toggle 10 cannot escape laterally and is forced to move upward between the branches of the fork 14 of the lever 15, which also raises the link 11 which brings its thrust surface 11a just in contact with the pin 25 of the pawl 3.
- the thrust surface 11a serves as a fulcrum for the pin 25 which constitutes a pivot around which the thrust surface 11a which simultaneously raises the pin 25 towards the position illustrated in Figure 2.
- the part of the perimeter surface of the pin 25, adjacent to the thrust surface 11a is rounded to facilitate the pivoting of the thrust surface 11a on the pin 25.
- the upper end portion of the link 11 is housed at sliding in a guide piece which is itself articulated on a fixed axis on the housing, to maintain the thrust surface 11a in line with line L, while allowing the inclination of the link 11, as illustrated in broken lines in FIG. 1.
- the lock of the invention differs only in that the guide piece 26 for the link 11 is articulated on an axis 27 which is slidably received in a groove 28 in the housing, instead to be fixed relative to it. So, as seen in Figure 4, when the control member is moved to its inhibited position shown in phantom, the thrust surface 11a of the link 11 moves laterally to the right with respect to line L, to maintain said thrust surface 11a oriented towards the pin 25. In other words, the thrust surface 11a is maintained perpendicular to the line passing through the toggle 10 and the pin 25.
- the knee lifter 10 is angularly moved in the direction the arrow F around the joint 8, and the link 11 tilts towards the left while sliding down inside the room guide 26 which itself translates to the right along the groove 28.
- the guide piece 26 can be in the form a flat plate whose lateral edges 26a are stamped with so as to form lateral guide rails for the link 11a.
- Figure 1 shows the lock in a position of start, in which the control member is in the active position (unlocked lock), and lever 5 in the rest position. If in these conditions, we exert an action on the door handle, we do tilt lever 5, in the direction of arrow P, as visible on Figure 2, bringing up the hinge pin 8 and therefore the assembly two links 7 and 11 which, being in the active position, will act during their displacement, by the thrust surface 11a, on the pin 25 to rotate the pawl 3 counterclockwise until reaching its escaped position. The links 7 and 11 will have undergone a vertical translation, which translation is authorized by the lever 15, because the toggle 10 will have slid vertically between the branches of the fork 14.
- FIG 1 there is shown in broken lines a other starting position of the lock, in which the control is in the inhibited position (lock locked) and the lever 5 in rest position.
- a action on the door handle and, at the same time, the motor is activated electric 24 by the emission of a unlocking signal produced, by example, by approaching a badge with the lock we will first the situation shown in Figure 3: the action on the door handle will, as in the previous case, raise the hinge pin 8 and so the set of two links 7 and 11, but the tilting of the knee pad 10 from its inhibited starting position to its active position does not will realize that later, because the electrical device is slower as the release mechanism. So, until the end of the movement actuation of the control member, the latter will remain in inhibited position, so that the pushing surface 11a will come just in contact with pin 25 at the end of the movement stroke actuating.
- the portion of the lever 15 extending between the hinge pin 16 and the fork 14 is clearly longer than the portion of the lever 15 extending between the axis hinge 16 and fork 17, so that the lever arm of the side of the knee lifter 10 is much more important, which allows a reduction of the efforts to be provided by the electric motor 24.
- the angular travel of the toggle joint 10 is reduced compared to that of the fork 17.
- an actuation is sufficient single door handle to get the opening of this last, despite the difference in response times that exists between that of the release mechanism, very fast, and that of the slower electric locking / unlocking device.
- the electronics of recognition is electrically powered only during action exerted on the handle by the user to open the door, in order to avoid unnecessary consumption of electrical energy.
- a microswitch or any other control system not shown, normally open, closing of which is ordered by an action on the door handle, this closing microswitch an electrical supply circuit, not shown, for the electronics of recognition.

Description
La présente invention concerne les serrures pour porte de véhicule automobile et, plus particulièrement, les serrures à condamnation électrique.The present invention relates to locks for motor vehicle and, more particularly, locks with electric lock.
De telles serrures comportent, de façon connue, un pêne à fourche destiné à coopérer avec une gâche, un cliquet assurant normalement le blocage du pêne en position fermée, un mécanisme de libération du pêne comportant un organe de commande subissant un mouvement d'actionnement en réponse à l'actionnement, par l'utilisateur, de la poignée de porte. L'organe de commande peut prendre une position active pour laquelle il agit, au cours de son mouvement d'actionnement, sur le cliquet pour le mettre en position échappée, et une position inhibée pour laquelle, lors de son mouvement d'actionnement, il est sans effet sur le cliquet. La serrure comporte, en outre, un dispositif électrique répondant au moins à un signal de décondamnation en déplaçant l'organe de commande jusqu'à l'atteinte de sa position active.Such locks comprise, in a known manner, a latch fork intended to cooperate with a keeper, a pawl ensuring normally locking the bolt in the closed position, a locking mechanism release of the bolt comprising a control member undergoing a actuation movement in response to actuation, by the user, from the door handle. The controller can take an active position for which he acts, during his actuation movement, on the pawl to put it in position escapement, and an inhibited position for which, during its movement actuation, it has no effect on the ratchet. The lock has, in in addition, an electrical device responding at least to a signal unlocking by moving the control member until it is reached from its active position.
On connaít des systèmes de fermeture de porte de véhicule dans lesquels le signal de décondamnation est généré par l'actionnement d'un barillet de serrure. Dans d'autres systèmes connus, ce signal de décondamnation est fourni par une électronique de reconnaissance en réponse à un signal de télécommande infrarouge ou de télécommande radioélectrique produit par l'utilisateur au moyen d'une télécommande appropriée.We know vehicle door closing systems in which the unlocking signal is generated by actuation of a lock cylinder. In other known systems, this unlocking signal is provided by electronic recognition in response to an infrared remote control signal or of radio remote control produced by the user by means of a suitable remote control.
Ces systèmes connus ne donnent pas entièrement satisfaction parce qu'ils nécessitent l'utilisation soit d'une clef soit d'une télécommande, ces objets occupant une main de l'utilisateur.These known systems do not give entirely satisfaction because they require the use of either a key or of a remote control, these objects occupying a hand of the user.
C'est pourquoi on a proposé des systèmes dits "d'accès au véhicule main libre" ne nécessitant pas l'utilisation de clef ni de télécommande pour décondamner la serrure. Ces systèmes sont équipés d'une électronique de reconnaissance munie d'un émetteur radio et conçue pour pouvoir dialoguer avec un dispositif radioélectrique incorporé dans une montre, une carte de crédit, un badge, ou analogue, porté par l'utilisateur. L'électronique de reconnaissance ne produit son signal de décondamnation qu'après identification du bon propriétaire. This is why we have proposed so-called "access to hands-free vehicle "not requiring the use of a key or remote control to unlock the lock. These systems are equipped recognition electronics fitted with a radio transmitter and designed to be able to communicate with a radio device incorporated in a watch, credit card, badge, or the like, worn by the user. Recognition electronics only produce sound unlocking signal only after identification of the correct owner.
Dans de tels systèmes, l'émission du signal de décondamnation commandant le dispositif électrique, d'une part, et l'actionnement du mécanisme de libération, d'autre part, ont lieu simultanément.In such systems, the transmission of the signal unlocking commanding the electrical device, on the one hand, and the actuation of the release mechanism, on the other hand, take place simultaneously.
Or la différence entre le temps de réponse, relativement long, du dispositif électrique et celui, très court, du mécanisme de libération est telle que l'organe de commande a terminé son mouvement d'actionnement alors qu'il n'est toujours pas en position active, si bien que la première action de l'utilisateur sur la poignée de porte n'entraíne pas l'ouverture de cette dernière et que ledit utilisateur doit agir à nouveau sur la poignée de porte pour en obtenir l'ouverture.Now the difference between the response time, relatively long, of the electrical device and that, very short, of the release is such that the control unit has completed its movement while it is still not in the active position, so that the first action of the user on the door handle does not not opening it and that said user must act on again on the door handle to open it.
Cette nécessité d'une double action sur la poignée de porte constitue un inconvénient que la présente invention se propose de supprimer.This need for a double action on the door handle constitutes a drawback that the present invention proposes to remove.
La présente invention a donc pour objet une serrure de porte de véhicule automobile, comportant : un pêne à fourche destiné à coopérer avec une gâche; un cliquet assurant normalement le blocage du pêne en position fermée et pouvant prendre une position "échappée" pour laquelle il n'agit plus sur ledit pêne ; un mécanisme de libération du pêne comportant un organe de commande, qui, d'une part, peut prendre soit une position active pour laquelle il agit, au cours de son mouvement d'actionnement, sur le cliquet pour le mettre en position "échappée", soit une position inhibée pour laquelle, lors de son mouvement d'actionnement, il est sans effet sur le cliquet et, d'autre part, peut subir un mouvement d'actionnement en réponse à l'actionnement par l'utilisateur de la poignée de porte ; et un dispositif électrique répondant au moins à un signal de décondamnation en déplaçant l'organe de commande depuis sa position inhibée jusqu'à l'atteinte de sa position active, caractérisée par le fait que l'organe de commande est constitué d'un ensemble de deux biellettes articulées entre elles par une genouillère, dont l'une des biellettes, dite première biellette, comporte une surface de poussée qui est positionnée de telle sorte que, lorsque l'organe de commande est en position active, la surface de poussée rencontre et entraíne un pion prévu sur le cliquet, au cours du mouvement d'actionnement de l'organe de commande, jusqu'à mettre ledit cliquet en position échappée, et que, lorsque l'organe de commande est en position inhibée, la surface de poussée se rapproche au plus en contact avec ledit pion, au cours du mouvement d'actionnement de l'organe de commande, si bien que l'organe de commande est sans action sur le cliquet, et dont l'autre biellette, dite deuxième biellette, est articulée sur un levier d'ouverture extérieure de la serrure destiné à déplacer l'organe de commande dans son mouvement d'actionnement en réponse à l'actionnement par l'utilisateur de la poignée de porte, et par le fait que le dispositif électrique précité comporte un levier de condamnation/décondamnation coopérant avec la genouillère pour la faire pivoter autour de l'articulation entre la deuxième biellette et le levier d'ouverture extérieure, de façon à augmenter la distance séparant le pion du cliquet de la genouillère, donc de la surface de poussée, lorsque l'organe de commande est déplacé dans sa position inhibée. En prévoyant un organe de commande à genouillère, on peut réduire le nombre de pièces en mouvement dans la serrure, ce qui permet de réaliser une serrure plus compacte.The present invention therefore relates to a lock for motor vehicle door, comprising: a fork bolt intended for cooperate with a striker; a ratchet normally ensuring blocking of the bolt in the closed position and can take an "escaped" position for which it no longer acts on said bolt; a release mechanism of the bolt comprising a control member, which, on the one hand, can take either an active position for which he acts, during his actuation movement, on the pawl to put it in position "breakaway" is an inhibited position for which, when actuation movement, it has no effect on the ratchet and, on the other hand, may be actuated in response to user actuation of the door handle; and a device electric responding at least to an unlocking signal in moving the control member from its inhibited position to reaching its active position, characterized in that the organ of control consists of a set of two articulated links between them by a kneepad, one of the rods, said first connecting rod, has a pushing surface which is positioned in such a way so that, when the control member is in the active position, the thrust surface meets and drives a pin provided on the pawl, during the actuation movement of the control member, until putting said pawl in the escaped position, and that, when the control member is in the inhibited position, the thrust surface is as close as possible in contact with said pawn, during the movement actuation of the control member, so that the control member command has no action on the ratchet, and the other link, called second link, is articulated on an external opening lever of the lock intended to move the control member in its actuation movement in response to actuation by the door handle user, and the fact that the device electric aforementioned includes a locking / unlocking lever cooperating with the toggle to rotate it around the articulation between the second link and the opening lever outside, so as to increase the distance between the pin and the pawl of the toggle, therefore of the thrust surface, when the control is moved to its inhibited position. By planning a knee switch control, you can reduce the number of moving parts in the lock, which allows for a more compact lock.
Dans une forme de réalisation particulière, le levier de condamnation/décondamnation comporte à une extrémité une fourchette entre les branches de laquelle est logé à coulissement l'axe de la genouillère pour permettre le mouvement d'actionnement de l'organe de commande, tant dans sa position inhibée que dans sa position active.In a particular embodiment, the lever conviction / unlocking has a fork at one end between the branches of which the axis of the toggle to allow actuation movement of the organ both in its inhibited position and in its active position.
Selon une autre caractéristique, la serrure comporte un moyen de rattrapage d'ouverture qui, lorsqu'il y a émission du signal de décondamnation sensiblement en fin de course du mouvement d'actionnement de l'organe de commande, amène le cliquet en position échappée, le moyen de rattrapage d'ouverture étant réalisé de la façon suivante : une partie de la surface de poussée et la partie adjacente de la surface de pourtour du pion du cliquet étant conformées et positionnées de manière à former respectivement un point d'appui et un pivot coopérant l'un avec l'autre lorsque l'organe de commande se trouve sensiblement en position de fin de mouvement d'actionnement, le déplacement de l'organe de commande par le levier de condamnation/décondamnation jusqu'à la position active entraínant, grâce à l'action du point d'appui sur le pivot, le pion du cliquet jusqu'à mettre ledit cliquet en position échappée. According to another characteristic, the lock comprises a opening catch-up means which, when the signal is emitted unlocking substantially at the end of the movement actuation of the control member, brings the pawl into position breakaway, the opening take-up means being carried out in the manner next: part of the thrust surface and the adjacent part of the perimeter surface of the pawl being shaped and positioned so as to form respectively a fulcrum and a pivot cooperating with each other when the control member substantially in the end position of actuation movement, the movement of the control member by the lever locking / unlocking up to the active driving position, thanks to the action of the fulcrum on the pivot, the pawl of the pawl up to put said pawl in the escaped position.
Ainsi, grâce à l'invention l'ouverture de la porte est obtenue par un actionnement unique de la poignée de porte, et ceci malgré la différence qui existe entre le temps de réponse du mécanisme de libération, très rapide, et celui du dispositif électrique de décondamnation, plus lent.Thus, thanks to the invention the opening of the door is obtained by a single actuation of the door handle, and this despite the difference between the response time of the mechanism release, very fast, and that of the electrical device unlocking, slower.
Selon encore une autre caractéristique, le dispositif électrique comporte un moteur électrique pour entraíner un mécanisme de transmission du mouvement qui agit sur l'extrémité, opposée à l'extrémité coopérant avec la genouillère, du levier de condamnation/décondamnation, ce levier étant articulé sur un axe fixe de la serrure en un point excentré du côté opposé à l'extrémité coopérant avec la genouillère, pour augmenter le bras de levier du côté de la genouillère. On obtient ainsi une démultiplication de l'effort à fournir par le moteur électrique pour déplacer la genouillère, ce qui permet d'utiliser un moteur électrique moins puissant que dans une serrure classique.According to yet another characteristic, the device electric has an electric motor to drive a mechanism of transmission of the movement which acts on the end, opposite to the end cooperating with the toggle joint, of the lever locking / unlocking, this lever being articulated on a fixed axis of the lock at an eccentric point on the side opposite the end cooperating with the knee lever, to increase the lever arm on the side knee brace. This gives a reduction in the effort to supplied by the electric motor to move the toggle switch, which allows to use a less powerful electric motor than in a classic lock.
Avantageusement, dans la position active, les deux biellettes de l'organe de commande sont sensiblement alignées en direction du pion du cliquet, et le levier de condamnation/ décondamnation coopère avec la genouillère de façon à permettre son déplacement dans ladite direction, lors du mouvement d'actionnement de l'organe de commande.Advantageously, in the active position, the two rods of the control member are substantially aligned in direction of the pawl, and the locking lever / unlocking cooperates with the kneepad so as to allow its displacement in said direction, during actuation movement of the control unit.
Inversement, on peut prévoir que, dans la position inhibée, les deux biellettes de l'organe de commande forment entre elles un angle obtus, la genouillère étant décalée latéralement par rapport à la ligne passant par le pion du cliquet et l'articulation entre la deuxième biellette et le levier d'ouverture extérieure.Conversely, one can predict that, in the inhibited position, the two rods of the control member form between them a obtuse angle, the knee lifter being laterally offset from the line passing through the pawl pin and the joint between the second connecting rod and external opening lever.
Selon une autre caractéristique, la première biellette est guidée, au cours du mouvement d'actionnement de l'organe de commande, tant dans sa position active que dans sa position inhibée, de façon à maintenir la surface de poussée sensiblement en direction du pion du cliquet.According to another characteristic, the first link is guided, during the actuation movement of the commands, both in its active position and in its inhibited position, to so as to maintain the thrust surface substantially in the direction of the pawl pin.
Dans une autre variante, la première biellette est guidée, au cours du mouvement d'actionnement de l'organe de commande, tant dans sa position active que dans sa position inhibée, de façon à maintenir la surface de poussée dans l'alignement du pion du cliquet et de l'articulation entre la deuxième biellette et le levier d'ouverture extérieure.In another variant, the first link is guided, during the actuating movement of the control member, both in its active position than in its inhibited position, so that keep the thrust surface in line with the pawl pin and the articulation between the second link and the opening lever exterior.
Avantageusement, la genouillère est une articulation bistable ayant deux positions angulaires stables correspondant aux positions inhibée et active de l'organe de commande.Advantageously, the knee brace is a bistable joint having two stable angular positions corresponding to inhibited and active positions of the control member.
Il est avantageux de prévoir que le signal de décondamnation est émis par une électronique de reconnaissance qui n'est alimentée électriquement que lors de l'action exercée sur la poignée de porte par l'utilisateur, ladite électronique identifiant alors un utilisateur autorisé par une émission radioélectrique échangée selon un protocole approprié avec un élément électronique porté par l'utilisateur ; ceci évite une consommation inutile d'énergie électrique. Ceci peut être obtenu par un micro-interrupteur (ou tout autre système de commande) normalement ouvert, dont la fermeture est commandée par l'action d'ouverture sur la poignée de porte, ce système de commande fermant un circuit d'alimentation électrique de l'électronique de reconnaissance.It is advantageous to provide that the signal unlocking is issued by recognition electronics which is electrically powered only during the action exerted on the door handle by the user, said electronics then identifying a user authorized by a radio emission exchanged according to a appropriate protocol with an electronic element carried by the user ; this avoids unnecessary consumption of electrical energy. This can be achieved by a microswitch (or any other system normally open, closing of which is ordered by the opening action on the door handle, this system of control closing a power supply circuit of recognition electronics.

Selon le premier mode de réalisation, la serrure
représentée sur les figures 1 à 3 comprend un boítier (non représenté),
un pêne à fourche 1 articulé en 2 sur le boítier, et un cliquet 3 articulé
en 4 sur le boítier. Le pêne 1 est destiné à coopérer, de façon connue,
avec une gâche non représentée. Le cliquet 3, de façon connue, est
associé à des moyens élastiques non représentés le sollicitant vers une
position assurant le blocage du pêne 1 en position fermée, telle que
représentée aux figures 1 et 3, et peut être mis en position "échappée"
à l'encontre desdits moyens élastiques, par un mécanisme de libération
du pêne, commandé par une poignée (ou palette) de porte, non
représentée.According to the first embodiment, the lock
represented in FIGS. 1 to 3 comprises a box (not shown),
a fork bolt 1 hinged in 2 on the housing, and a
Le mécanisme de libération du pêne comprend un levier
d'actionnement 5, également appelé levier d'ouverture extérieure,
articulé en 6 sur le boítier, une biellette 7 articulée par son extrémité
inférieure en 8 sur l'extrémité gauche du levier 5, et par son extrémité
supérieure en 10 sur l'extrémité inférieure d'une autre biellette 11.
L'axe d'articulation 10 constitue une charnière mobile entre les deux
biellettes 7 et 11 qui forment ensemble un organe de commande à
genouillère pour le cliquet 3. Les deux biellettes 7 et 11 s'étendent dans
une direction sensiblement verticale sur les figures 1 et 2.The bolt release mechanism includes a
Le levier 5 est articulé par son extrémité droite en 12 à une
tringle d'ouverture non représentée qui est reliée à une poignée de
porte. Le levier 5 est associé à des moyens élastiques le sollicitant vers
sa position de repos dans laquelle il a été représenté sur la figure 1. Le
levier 5 est destiné à venir en butée contre une saillie 13 prévue sur le
boítier de serrure, pour limiter le pivotement du levier 5, dans sa
course d'actionnement de l'organe de commande.The
L'axe d'articulation de la genouillère 10 est logé à
coulissement entre les branches d'une fourchette 14, représentée
schématiquement et uniquement sur la figure 3, faisant partie d'un
dispositif électrique de condamnation/décondamnation de la serrure. La
fourchette 14 est prévue à une extrémité d'un levier 15 qui est articulé
en 16 sur un axe fixe sur le boítier B et qui comporte à son extrémité
opposée une autre fourchette 17 entre les branches de laquelle est reçu
un pion 18 prévu en saillie sur un écrou 19. L'écrou 19 est apte à se
translater longitudinalement sur une vis sans fin 20, lors de son
entraínement en rotation, ladite vis 20 étant solidaire en rotation d'une
roue dentée 21 qui engrène tangentiellement avec un pignon
d'engrenage 22 qui est entraíné à son tour, par l'arbre moteur 23 d'un
moteur électrique 24. L'ensemble des éléments 14 à 24 constitue le
dispositif électrique de condamnation/décondamnation. Le levier de
condamnation/décondamnation 15 peut prendre deux positions fixes par
rapport au boítier de serrure. Une position dite condamnée pour le
levier 15 est représentée sur la figure 3 et correspond à une position
angulaire dite inhibée de la genouillère 10 et donc de l'organe de
commande. L'autre position dite de décondamnation du levier 15 n'est
pas représentée, mais correspond à la position angulaire dite active de
la genouillère 10 et donc de l'organe de commande, représentée sur les
figures 1 et 2. Le moteur 24 de l'actionneur électrique est conçu pour
répondre à un signal de condamnation et à un signal de
décondamnation, faisant translater axialement l'écrou 19 sur la vis sans
fin 20, de manière à déplacer le levier 15 autour de son axe 16 entre sa
position de condamnation (et par suite, la genouillère 10 dans sa
position inhibée), et dans sa position de décondamnation (et par suite,
la genouillère 10 dans sa position active).The axis of articulation of the
Le signal de décondamnation peut être émis par une électronique de reconnaissance, non représentée, faisant partie d'un système connu en soi "d'accès au véhicule main libre" ne nécessitant pas l'utilisation de clef ni de télécommande pour décondamner la serrure. Dans ce système, l'électronique de reconnaissance est équipée d'un émetteur radio et est conçue pour pouvoir dialoguer avec un dispositif radioélectrique incorporé dans une montre, ou une carte, ou un badge, porté par l'utilisateur. L'électronique de reconnaissance ne produit son signal de décondamnation qu'après identification du bon propriétaire.The unlocking signal can be issued by a recognition electronics, not shown, forming part of a system known per se "hands-free vehicle access" not requiring not use a key or remote control to unlock the lock. In this system, the recognition electronics are equipped of a radio transmitter and is designed to be able to communicate with a radio device incorporated into a watch, or card, or a badge, worn by the user. Recognition electronics don't produces its unlocking signal only after identification of the correct owner.
Pour chaque position fixe du levier de
condamnation/décondamnation 15, lorsque l'on fait pivoter le levier
d'actionnement 5 dans le sens de la flèche P sur les figures 2 et 3, en
actionnant la poignée de porte, l'organe de commande subit un
mouvement dit d'actionnement, dirigé vers le haut, au cours duquel la
biellette 11 pourra ou ne pourra pas agir sur le cliquet 3 pour le mettre
en position "échappée" (position représentée sur la figure 2), comme
cela sera expliqué plus loin.For each fixed position of the
locking / unlocking 15, when the lever is pivoted
La biellette 11 comporte à son extrémité supérieure une
surface de poussée 11a sensiblement plane et perpendiculaire à la
direction verticale sur les figures 1 et 2. Le cliquet 3 comporte sur sa
face tournée vers la biellette 11 un pion 25 faisant saillie en direction
de ladite biellette 11.The
Les éléments 5 à 13 constituant le mécanisme de libération
du pêne, et le pion 25 du cliquet 3 sont agencés ensemble de telle sorte
que, lorsque l'organe de commande se trouve en position angulaire
active (figures 1 et 2), la biellette 11 puisse, lors de son mouvement
d'actionnement, agir sur le cliquet 3, par l'action de la surface plane de
poussée 11a sur le pion 25, pour mettre le cliquet 3 en position
échappée et que, lorsque l'organe de commande est en position
angulaire inhibée, lors de son mouvement d'actionnement, la biellette
11 soit sans effet sur le cliquet 3, la surface de poussée 11a restant
alors, tout au long du mouvement d'actionnement, sensiblement à
distance du pion 25 et venant juste en contact avec le pion 25 en fin de
course d'actionnement, dans la position illustrée sur la figure 3. La
position angulaire inhibée de l'organe de commande, lorsque le levier 5
est en position de repos, est représentée en traits mixtes sur la figure 1.
Dans cette position, on constate que la genouillère 10 a été
angulairement déplacée vers la droite, par pivotement autour de
l'articulation 8, sous l'action de la fourchette 14 du levier de
condamnation/décondamnation 15, la biellette 7 étant inclinée vers la
droite par rapport à la direction verticale, alors que la biellette 11 est
inclinée dans la direction opposée par rapport à la verticale, de façon à
maintenir la surface de poussée 11a sensiblement dans l'alignement
avec la ligne L passant par le pion 25 et l'articulation 8. Dans la
position illustrée en traits mixtes sur la figure 1, les deux biellettes 7 et
11 de l'organe de commande forment ensemble un angle sensiblement
obtus, mais on pourrait prévoir en variante qu'elles forment un angle
aigu, sans sortir du cadre de l'invention.
Dans la position illustrée sur la figure 3, le levier 5 est en
position actionnée, et l'organe de commande de la genouillère conserve
sensiblement la forme coudée qui est visible en traits mixtes sur la
figure 1. En effet, lors du pivotement du levier 5 autour de son axe 6,
l'articulation 8 se soulève et déplace vers le haut la biellette 7, et par
suite, la genouillère 10, car l'axe de la genouillère 10 ne peut échapper
latéralement et est forcé à se déplacer vers le haut entre les branches de
la fourchette 14 du levier 15, ce qui conduit à soulever également la
biellette 11 qui amène sa surface de poussée 11a juste en contact avec
le pion 25 du cliquet 3. Ainsi, lorsque l'organe de commande est
sensiblement en fin de mouvement d'actionnement, comme représenté
sur la figure 3, et que la genouillère 10 est entraínée par le levier 15
vers sa position active, la surface de poussée 11a sert de point d'appui
pour le pion 25 qui constitue un pivot autour duquel se déplace la
surface de poussée 11a qui, simultanément, soulève le pion 25 vers la
position illustrée sur la figure 2. La partie de la surface de pourtour du
pion 25, adjacente à la surface de poussée 11a est arrondie pour
faciliter le pivotement de la surface de poussée 11a sur le pion 25.In the position illustrated in FIG. 3, the
Bien que cela ne soit pas représenté sur les figures 1 à 3, la
portion d'extrémité supérieure de la biellette 11 est logée à
coulissement dans une pièce de guidage qui est elle-même articulée sur
un axe fixe sur le boítier, pour maintenir la surface de poussée 11a
dans l'alignement de la ligne L, tout en permettant l'inclinaison de la
biellette 11, comme illustré en traits interrompus sur la figure 1.Although not shown in Figures 1 to 3, the
upper end portion of the
Dans l'autre mode de réalisation représenté sur les figures
4 et 4A, la serrure de l'invention diffère uniquement par le fait que la
pièce de guidage 26 pour la biellette 11 est articulée sur un axe 27 qui
est reçu à coulissement dans une rainure 28 dans le boítier, au lieu
d'être fixe par rapport à celui-ci. Ainsi, comme visible sur la figure 4,
lorsque l'organe de commande est déplacé dans sa position inhibée
représentée en traits mixtes, la surface de poussée 11a de la biellette 11
se déplace latéralement vers la droite par rapport à la ligne L, pour
maintenir ladite surface de poussée 11a orientée en direction du pion
25. Autrement dit, la surface de poussée 11a est maintenue
perpendiculaire à la ligne passant par la genouillère 10 et le pion 25.
Ainsi, lorsque l'organe de commande est déplacé dans sa position
inhibée, la genouillère 10 est déplacée angulairement dans la direction
de la flèche F autour de l'articulation 8, et la biellette 11 s'incline vers
la gauche, tout en coulissant vers le bas à l'intérieur de la pièce de
guidage 26 qui, elle-même, se translate vers la droite le long de la
rainure 28.In the other embodiment shown in the figures
4 and 4A, the lock of the invention differs only in that the
La pièce de guidage 26 peut se présenter sous la forme
d'une plaquette plane dont les bords latéraux 26a sont emboutis de
manière à former des rails de guidage latéraux pour la biellette 11a.The
Le fonctionnement de la serrure représentée sur les figures 1 à 3 est le suivant.The operation of the lock shown in the figures 1 to 3 is as follows.
La figure 1 représente la serrure dans une position de
départ, dans laquelle l'organe de commande est en position active
(serrure décondamnée), et le levier 5 en position de repos. Si, dans ces
conditions, on exerce une action sur la poignée de porte, on fait
basculer le levier 5, dans la direction de la flèche P, comme visible sur
la figure 2, faisant remonter l'axe d'articulation 8 et donc l'ensemble
des deux biellettes 7 et 11 qui, se trouvant en position active, agiront au
cours de leur déplacement, par la surface de poussée 11a, sur le pion
25 pour faire pivoter le cliquet 3 dans le sens anti-horaire jusqu'à
l'atteinte de sa position échappée. Les biellettes 7 et 11 auront subi une
translation verticale, laquelle translation est autorisée par le levier 15,
car la genouillère 10 aura coulissé verticalement entre les branches de
la fourchette 14.Figure 1 shows the lock in a position of
start, in which the control member is in the active position
(unlocked lock), and
Sur la figure 1, on a représenté en traits interrompus une
autre position de départ de la serrure, dans laquelle l'organe de
commande se trouve en position inhibée (serrure condamnée) et le
levier 5 en position de repos. Si, dans ces conditions, on exerce une
action sur la poignée de porte et, en même temps, on active le moteur
électrique 24 par l'émission d'un signal de décondamnation produit, par
exemple, en approchant un badge de la serrure, on aboutira d'abord à
la situation représentée sur la figure 3 : l'action sur la poignée de porte
fera, comme dans le cas précédent, remonter l'axe d'articulation 8 et
donc l'ensemble des deux biellettes 7 et 11, mais le basculement de la
genouillère 10 de sa position inhibée de départ à sa position active ne se
réalisera que plus tard, parce que le dispositif électrique est plus lent
que le mécanisme de libération. Ainsi, jusqu'à la fin du mouvement
d'actionnement de l'organe de commande, ce dernier demeurera en
position inhibée, de sorte que la surface de poussée 11a viendra juste
en contact avec le pion 25 en fin de course de mouvement
d'actionnement.In Figure 1, there is shown in broken lines a
other starting position of the lock, in which the
control is in the inhibited position (lock locked) and the
Quand le dispositif électrique commence à agir en tirant
vers la gauche, sur la figure 3, la genouillère 10, grâce au point
d'appui réalisé par la surface de poussée 11a contre la forme arrondie
du pion 25 servant de pivot, il n'y aura pas blocage du pion 25 contre
la biellette 11, mais au contraire, le pion 25 se soulèvera entraínant,
par suite, le pivotement du cliquet 3 dans le sens anti-horaire, jusqu'à
amener ledit cliquet dans sa position échappée, telle que représentée sur
la figure 2, pour laquelle le cliquet n'agit plus sur le pêne à fourche 1,
autorisant ainsi l'ouverture de la porte.When the electrical device begins to act by pulling
to the left, in Figure 3, the
Comme visible sur la figure 3, la portion du levier 15
s'étendant entre l'axe d'articulation 16 et la fourchette 14 est nettement
plus longue que la portion du levier 15 s'étendant entre l'axe
d'articulation 16 et la fourchette 17, de sorte que le bras de levier du
côté de la genouillère 10 est bien plus important, ce qui permet une
démultiplication des efforts à fournir par le moteur électrique 24. En
effet, la course angulaire de la genouillère 10 est réduite par rapport à
celle de la fourchette 17.As shown in Figure 3, the portion of the
Ainsi, grâce à l'invention, il suffit d'un actionnement unique de la poignée de porte pour obtenir l'ouverture de cette dernière, et ceci malgré la différence des temps de réponse qui existe entre celui du mécanisme de libération, très rapide, et celui du dispositif électrique de condamnation/décondamnation, plus lent.Thus, thanks to the invention, an actuation is sufficient single door handle to get the opening of this last, despite the difference in response times that exists between that of the release mechanism, very fast, and that of the slower electric locking / unlocking device.
Il est avantageux de prévoir que l'électronique de reconnaissance n'est alimentée électriquement que lors de l'action exercée sur la poignée par l'utilisateur pour ouvrir la porte, ceci afin d'éviter une consommation inutile d'énergie électrique. Ceci peut être obtenu par un micro-interrupteur (ou tout autre système de commande) non représenté, normalement ouvert, dont la fermeture est commandée par une action sur la poignée de porte, ce micro-interrupteur fermant un circuit d'alimentation électrique, non représenté, de l'électronique de reconnaissance.It is advantageous to provide that the electronics of recognition is electrically powered only during action exerted on the handle by the user to open the door, in order to avoid unnecessary consumption of electrical energy. This can be obtained by a microswitch (or any other control system) not shown, normally open, closing of which is ordered by an action on the door handle, this closing microswitch an electrical supply circuit, not shown, for the electronics of recognition.
