Description

La présente invention concerne un dispositif électromécanique pour la commande à distance de l'ouverture d'une serrure et de la porte correspondante d'un véhicule automobile, comprenant un actionneur muni d'un moteur électrique, d'un moyen de démultiplication et d'un organe de commande actionné par lesdits moyens de démultiplication, ledit dispositif comprenant un organe primaire de manoeuvre déplaçable, relié à l'organe de commande et agissant sur un levier d'ouverture de la serrure, ledit organe primaire étant déplaçable à partir d'une position de repos. Par l'expression "commande à distance" on entend ici de se référer avec la plus grande amplitude à tout genre de commande effectuée sans connexion mécanique directe à la serrure de la porte, au moyen d'un interrupteur électrique installé n'importe où, ou bien au moyen d'une station centralisée installée, par exemple, sur le tableau d'instruments et agissant séparément ou collectivement sur les différentes serrures et portes du véhicule, ou même au moyen d'un appareil de véritable télécommande agissant de l'extérieur du véhicule.The present invention relates to an electromechanical device for the remote control of the opening of a lock and of the corresponding door of a motor vehicle, comprising an actuator provided with an electric motor, a gear reduction and a control member actuated by said reduction means, said device comprising a movable primary operating member, connected to the control member and acting on a lever for opening the lock, said primary member being movable from a rest position. By the expression "remote control" is meant here to refer with the greatest amplitude to any kind of control carried out without direct mechanical connection to the door lock, by means of an electric switch installed anywhere, or by means of a centralized station installed, for example, on the instrument panel and acting separately or collectively on the various locks and doors of the vehicle, or even by means of a real remote control device acting from the outside of the vehicle.

Des dispositifs électromécaniques destinés à effectuer à distance la commande de condamnation et de décondamnation de la serrure de la porte d'un véhicule automobile sont bien connus, et ils ont atteint une diffusion considérable. Ces dispositifs comprennent substantiellement un actionneur constitué par un moteur électrique, un engrenage de démultiplication entraîné par le moteur et une tige en forme di crémaillère actionnée par l'engrenage de démultiplication et reliée, par des moyens cinématiques appropriés, à un organe de la serrure qui, lors qu'il est déplacé dans un sens, donne lieu à la condamnation de la serrure, tandis que, lors qu'il est déplace dans le sens opposé, il pourvoit à la décondamnation de la serrure.Electromechanical devices intended to remotely control the locking and unlocking of the lock of the door of a motor vehicle are well known, and they have reached considerable diffusion. These devices substantially comprise an actuator constituted by an electric motor, a reduction gear driven by the motor and a rack-shaped rod actuated by the reduction gear and connected, by suitable kinematic means, to a member of the lock which , when it is moved in one direction, gives rise to the locking of the lock, while, when it is moved in the opposite direction, it provides for unlocking the lock.

On connait aussi, bien qu'ils n'ont pas une grande diffusion, des dispositifs électromécaniques destinés à effectuer à distance la commande de l'ouverture de la porte d'un véhicule, l'ouverture étant entendue dans le sens d'actionner les moyens d'ouverture de la serrure et, par conséquent, de la porte correspondante, non pas dans le sens de la décondamnation de la serrure. Un tel dispositif électromécanique d'ouverture, du type énoncé plus haut ou encore dans le préambule de la revendication 1, est - connu par le document de brevet EP-A-159.238. Comme les autres dispositifs de ce genre, ce dispositif ne pourvoit pas à la commande de la condamnation et décondamnation de la serrure. Tout au contraire, son fonctionnement serait empêché, en principe, par la présence d'un dispositif de condamnation de la serrure, par exemple du type à commande manuelle connu par le document de brevet GB-A-2,045,336, dans lequel un verrou retenant en position active les organes d'accrochage de la serrure ne peut pas être déplacé lors que le dispositif de condamnation est en activité. L'installation d'un tel dispositif d'ouverture de la porte serait d'une utilité très limitèe s'il ne serait pas accompagné aussi par un dispositif destiné à effectuer à distance la commande de la condamnation et de la décondamnation de la serrure. Cependant, l'application des deux dispositifs et, par conséquent, des deux actionneurs respectifs, porte à la formation d'ensembles très coûteux et encombrants, et cela jusqu'à présent a limité la diffusion des dispositifs électromécaniques d'ouverture de la porte. D'autre côté, une unification des deux dispositifs en question, et particulièrement de leurs actionneurs, n'a pas été réalisée jusqu'à présent, ni avait-elle été considerée possible pour la double raison que ces deux dispositifs doivent généralement pouvoir être commandés indépendamment l'un de l'autre, et qu'ils sont destinés à agir sur des organes différents de la serrure.We also know, although they do not have a wide distribution, electromechanical devices intended to remotely control the opening of the door of a vehicle, the opening being heard in the direction of actuating the means for opening the lock and, consequently, the corresponding door, not in the direction of unlocking the lock. Such an electromechanical opening device, of the type stated above or also in the preamble of claim 1, is - known from patent document EP-A-159,238. Like other devices of this kind, this device does not provide for the control of the locking and unlocking of the lock. Quite the contrary, its operation would be prevented, in principle, by the presence of a device for locking the lock, for example of the type with manual control known from patent document GB-A-2,045,336, in which a lock retaining in active position the latching members of the lock cannot be moved when the locking device is active. The installation of such a door opening device would be of very limited use if it were not also accompanied by a device intended to remotely control the locking and unlocking of the lock. However, the application of the two devices and, consequently, of the two respective actuators, leads to the formation of very expensive and bulky assemblies, and this has so far limited the diffusion of the electromechanical devices for opening the door. On the other hand, a unification of the two devices in question, and particularly of their actuators, has not been achieved so far, nor had it been considered possible for the double reason that these two devices must generally be able to be controlled independently of each other, and that they are intended to act on organs different from the lock.

Le but de la présente invention est de réaliser un dispositif électromécanique unique, capable d'effectuer à distance soit la commande de condamnation et de décondamnation de la serrure, soit la commande d'ouverture de la serrure et, par conséquent, de la porte d'un véhicule; à savoir, en d'autres termes, de réaliser un dispositif pour effectuer à distance la commande d'ouverture de la serrure et de la porte d'un véhicule, qui soit capable aussi, au moyen de son actionneur unique, d'effectuer aussi la commande de condamnation et de décondamnation de la serrure de la porte.The object of the present invention is to provide a unique electromechanical device capable of carrying out remotely either the locking and unlocking control of the lock, or the opening control. the lock and, therefore, the door of a vehicle; namely, in other words, to provide a device for remotely controlling the opening of the lock and the door of a vehicle, which is also capable, by means of its single actuator, of also performing the locking and unlocking control for the door lock.

Ce but est atteint, selon la présente invention, au moyen d'un dispositif électromécanique comme indiqué au principe, caractérisé en ce que l'organe primaire de manoeuvre est déplaçable à partir de ladite position de repos dans les deux sens, à savoir un sens pour effectuer l'ouverture de la serrure et le sens opposé; qu'un organe secondaire de manoeuvre est monté à coulissement sur ledit organe primaire de manoeuvre avec interposition d'un moyen élastique permettant à l'organe secondaire de manouvre, au moins pour un sens de déplacement de l'organe primaire de manoeuvre, de ne pas suivre le déplacement dudit organe primaire de manoeuvre sur toute sa course; et que l'organe secondaire de manoeuvre est relié à un organe de manoeuvre manuelle permettant la condamnation et la décondamnation manuelle de la serrure, un jeu étant prévu à la liaison entre l'organe primaire de manoeuvre et l'organe de manoeuvre manuelle, ledit jeu correspondant à la course opérationnelle de l'organe de condamnation et de décondamnation de la serrure.This object is achieved, according to the present invention, by means of an electromechanical device as indicated in principle, characterized in that the primary operating member is movable from said rest position in both directions, namely a direction to open the lock and the opposite direction; that a secondary operating member is slidably mounted on said primary operating member with the interposition of an elastic means allowing the secondary operating member, at least for a direction of movement of the primary operating member, not to not follow the movement of said primary operating member over its entire travel; and that the secondary operating member is connected to a manual operating member allowing the manual locking and unlocking of the lock, a clearance being provided at the connection between the primary operating member and the manual operating member, said clearance corresponding to the operational travel of the locking and unlocking member of the lock.

Grâce à ces caractéristiques, la présence de l'organe secondaire de manoeuvre n'empêche pas la commande manuelle de la condamnation et de la décondamnation de la serrure, laquelle est autorisée par ledit jeu mécanique correspondant à la course de l'organe de commande manuelle qui réalise ces opérations. Un déplacement de l'organe primaire de manoeuvre, déterminé par l'actionneur, dans le sens opposé au sens d'ouverture de la porte, est autorisé par la mobilité dans ce sens, prévue à cet effet dans le montage de l'organe primaire de manoeuvre, et ce déplacement n'agit pas sur le levier d'ouverture, mais il donne lieu à un déplacement de l'organe secondaire de manoeuvre, lequel entraîne avec soi l'organe di manoeuvre manuelle jusqu'à la position de condamnation de la serrure, si l'organe de manoeuvre manuelle ne se trouve pas déjà dans cette position. Si, au contraire, l'organe de manoeuvre manuelle se trouve déjà dans la position de condamnation, l'organe secondaire de manouevre se limite à parcourir le jeu mécanique prévu.Thanks to these characteristics, the presence of the secondary operating member does not prevent manual control of the locking and unlocking of the lock, which is authorized by said mechanical clearance corresponding to the stroke of the manual control member who performs these operations. A movement of the primary operating member, determined by the actuator, in the direction opposite to the direction of opening of the door, is authorized by mobility in this direction, provided for this purpose in the mounting of the primary member maneuver, and this movement does not act on the opening lever, but it gives rise to a movement of the secondary maneuvering member, which carries with it the manual di operating member to the locking position of the lock, if the manual operating member is not already in this position. If, on the contrary, the manual operating member is already in the locking position, the secondary operating member is limited to traversing the intended mechanical play.

Un déplacement de l'organe primaire de manoeuvre, produit par l'actionneur dans le sens d'ouverture de la porte, mais pour une extension inférieure à celle prévue pour cette opération, ne donne pas lieu à l'ouverture, mais il donne lieu à un déplacement de l'organe secondaire de manoeuvre, lequel entraîne avec soi l'organe de manoeuvre manuelle jusqu'à la position de décondamnation de la serrure, si l'organe de manoeuvre manuelle ne se trouve pas déjà dans cette position. Si, au contraire, l'organe de manoeuvre manuelle se trouve déjà dans la position de décondamnation, l'organe secondaire de manoeuvre se limite à parcourur le jeu mécanique prévu.A displacement of the primary operating member, produced by the actuator in the direction of opening of the door, but for an extension smaller than that provided for this operation, does not give rise to opening, but it gives rise to a movement of the secondary operating member, which carries with it the manual operating member to the unlocking position of the lock, if the manual operating member is not already in this position. If, on the contrary, the manual operating member is already in the unlocked position, the secondary operating member is limited to traversing the mechanical clearance provided.

Enfin, un déplacement de l'organe primaire de manoeuvre, déterminé par l'actionneur dans le sens d'ouverture de la porte, et pour toute l'extension prévue pour cette opération, détermine d'abord un déplacement de l'organe secondaire de manoeuvre, lequel entraîne avec soi l'organe de manoeuvre manuelle jusqu'à la position de décondamnation de la serrure, si l'organe de manoeuvre manuelle ne se trouvait pas dejà dans cette position, tandis qu'il se limite à parcourir le jeu mécanique prévu si l'organe de manoeuvre manuelle se trouvait déjà dans la position de décondamnation, et cela dans les limites de mouvement accordées à l'organe secondaire de manoeuvre, après quoi le moyen élastique interposé entre les organes de manoeuvre primaire et secondaire permet à l'organe secondaire de manoeuvre de s'arrêter, tandis que l'organe primaire de manoeuvre poursuit sa course, en chargeant le moyen élastique, jusqu'à la réalisation de l'ouverture de la serrure et de la porte, ouverture qui en tous cas a déjà été autorisée par la décondamnation précédemment effectuée.Finally, a movement of the primary operating member, determined by the actuator in the direction of opening of the door, and for the entire extension provided for this operation, first determines a movement of the secondary member of maneuver, which carries with it the manual operating member to the unlocking position of the lock, if the manual operating member was not already in this position, while it is limited to traversing the mechanical play provided if the manual operating member was already in the unlocked position, and this within the limits of movement granted to the secondary operating member, after which the elastic means interposed between the primary and secondary operating members allows the secondary operating member to stop, while the primary operating member continues to run, loading the elastic means, until the opening of the lock and of the por te, opening which in any case has already been authorized by the unlocking previously carried out.

De ce fait, grâce aux caractéristiques de l'invention, un actionneur unique est mis en condition de commander indépendamment les opéra-tions de condamnation de la serrure, de décondamnation et d'ouverture de la porte, en fonction du sens de déplacement pour lequel il est activé, et de l'amplitude du déplacement même. Il devient donc possible de réaliser des ensembles très compactes et économiques capables d'effectuer à distance toutes les opérations qui peuvent être requises sur la serrure d'une porte de véhicule, lesquelles peuvent être commandées par des postes de commande spécifiques pour chaque porte du véhicule, ou bien peuvent être commandées par un poste centralisé, collectivement pour toutes les serrures et les portes du véhicule même ou bien sélectivement pour les différentes serrures et portes, ou bien encore peuvent être commandées à l'aide d'un véritable dispositif de télécommande, de l'intérieur ou de l'extérieur du véhicule.As a result, thanks to the characteristics of the invention, a single actuator is placed in a condition to independently control the operations. for locking the lock, unlocking and opening the door, depending on the direction of movement for which it is activated, and the amplitude of the movement itself. It therefore becomes possible to produce very compact and economical assemblies capable of remotely carrying out all the operations which may be required on the lock of a vehicle door, which can be controlled by specific control stations for each vehicle door , either can be controlled by a centralized station, collectively for all the locks and doors of the vehicle itself or selectively for the different locks and doors, or else can be controlled using a real remote control device, from inside or outside the vehicle.

L'invention est représentée dans son application à un type particulier de serrure pour véhicules, connu en soi-même par le document de brevet GB-A-2,045,336, comportant deux organes d'accrochage à déplacement symétrique contrôlés par un verrou, mais on doit entendre que par des adaptations appropriées l'invention peut être appliquée à n'importe quel type de serrure pour véhicules. En particulier, à cet effet, des mécanismes d'inversion du mouvement peuvent naturellement être prévus lors que les organes de la serrure à manoeuvrer demandent un déplacement en sens opposé au sens de déplacement des organes du dispositif selon l'invention.The invention is represented in its application to a particular type of lock for vehicles, known in itself from the document of Patent GB-A-2,045,336, comprising two coupling members with symmetrical displacement controlled by a lock, but it should be understood that by appropriate adaptations the invention can be applied to any type of lock for vehicles. In particular, for this purpose, mechanisms for reversing the movement can naturally be provided when the members of the lock to be operated require movement in the opposite direction to the direction of movement of the members of the device according to the invention.

La serrure représentée comprend dans sa structure une plaque inférieure 1 et une plaque supérieure 3, cette dernière s'étendant de façon à former une console 4 pour supporter l'actionneur électromécanique. Les composants opérationnels de la serrure sont logés principalment entre les deux plaques 1 et 3. Dans la forme de serrure, connue en soi--même, représentée à titre d'exemple, les composants, comme il est montré particulièrement dans la figure 3, comprennent deux organes d'accrochage 7, pivotants sur des pivots 6 supportés par les plaques 1 et 3. Les organes d'accrochage sont représentés dans la condition de fermeture de la serrure, et ils sont pourvus de ressorts (non représentés) qui les poussent vers la condition d'ouverture. Le déplacement d'ouverture des organes d'accrochage est empêché par un verrou 9, qui est poussé par un ressort 8 et qui peut être retiré, ainsi l'éloignant des organes d'accrochage, en agissant sur un goujon 10 dont il est pourvu. Cette action est confiée à un levier d'ouverture 12, pivotant sur un pivot 11 supporté par les plaques 1 et 3, et ayant une oreille 13 sur laquelle agit la poignée extérieure d'ouverture de la porte, ainsi qu'un bras 14 avec lequel coopère un levier 16, qui est pivoté sur une partie pliée 2 de la plaque 1, et sur lequel agit la poignée intérieure d'ouverture de la porte. Le levier d'ouverture 12 est aussi pourvu d'un deuxième bras 15 destiné à déplacer le verrou 9.The lock shown comprises in its structure a lower plate 1 and an upper plate 3, the latter extending so as to form a console 4 for supporting the electromechanical actuator. The operational components of the lock are housed mainly between the two plates 1 and 3. In the form of lock, known per se, shown by way of example, the components, as shown particularly in FIG. 3, comprise two hooking members 7, pivoting on pivots 6 supported by the plates 1 and 3. The hooking members are shown in the lock closing condition, and they are provided with springs (not shown) which push them towards the opening condition. The opening movement of the hooking members is prevented by a latch 9, which is pushed by a spring 8 and which can be removed, thus moving it away from the hooking members, by acting on a stud 10 with which it is provided. . This action is entrusted to an opening lever 12, pivoting on a pivot 11 supported by the plates 1 and 3, and having an lug 13 on which the exterior door opening handle acts, as well as an arm 14 with which cooperates with a lever 16, which is pivoted on a folded part 2 of the plate 1, and on which the interior door opening handle acts. The opening lever 12 is also provided with a second arm 15 intended to move the lock 9.

Le déplacement du levier d'ouverture 12 peut être transmis au goujon 10 du verrou 9 par un organe de manoeuvre manuelle 17 qui préside à la condamnation de la serrure, qui est pivoté en 22 et qui peut être déplacé en direction longitudinale jusqu'à la position illustrée (serrure condamnée) ou bien jusqu'à une position déplacée vers le bas par rapport à la figure 3 (serrure décondamnée) sous l'action d'un levier 21 pivoté sur une partie pliée 5 de la plaque 3 et relié à l'organe de manoeuvre manuelle de la condamnation (habituellement un poussoir ou un levier). L'organe de manoeuvre manuelle 17 a une extrémité pliée 18 qui dans la condition de décondamnation coopère avec le bras 15 du levier d'ouverture 12, una fente 19 dans laquelle engage le goujon 10 du verrou 9, et une fente ultérieure d'éxtremité 20 pour la commande électromécanique. Dans la position de condamnation représentée, l'extrémité pliée 18 de l'organe 17 n'interfère pas avec la trajectoire du bras 15 du levier d'ouverture 12, et par conséquent le levier d'ouverture se déplace à vide et il ne peut pas donner lieu à l'ouverture de la porte. Lors que l'organe de manoeuvre manuelle 17 est déplacé vers le bas, l'extrémité pliée 18 fait face au bras 15 du levier d'ouverture 12, et par conséquent la manoeuvre de ce dernier fait déplacer l'organe 17, le goujon 10 et le verrou 9, ainsi libérant les organes d'accrochage 7 qui alors, poussés par leurs ressorts, passent à la position d'ouverture.The movement of the opening lever 12 can be transmitted to the stud 10 of the latch 9 by a manual operating member 17 which presides over the locking of the lock, which is pivoted at 22 and which can be moved in the longitudinal direction to the illustrated position (locked lock) or to a position moved down relative to FIG. 3 (unlocked lock) under the action of a lever 21 pivoted on a folded part 5 of the plate 3 and connected to the manual operating member of the lock (usually a pusher or a lever). The manual operating member 17 has a folded end 18 which in the unlocking condition cooperates with the arm 15 of the opening lever 12, a slot 19 in which engages the stud 10 of the bolt 9, and a subsequent end slot 20 for electromechanical control. In the locked position shown, the folded end 18 of the member 17 does not interfere with the trajectory of the arm 15 of the opening lever 12, and therefore the opening lever moves empty and it cannot not open the door. When the manual operating member 17 is moved downward, the folded end 18 faces the arm 15 of the opening lever 12, and therefore the operation of the latter causes the member 17, the stud 10, to move. and the latch 9, thus releasing the hooking members 7 which then, pushed by their springs, pass to the open position.

Pour l'actionnement électromécanique, sur la console 4 est monté un actionneur 23, décrit plus en détail par la suite, dont l'action se manifeste par le déplacement d'une tige interne 43, protégée par un soufflet 25 et se terminant par un oeillet 24.For electromechanical actuation, on the console 4 is mounted an actuator 23, described in more detail below, whose action is manifested by the displacement of an internal rod 43, protected by a bellows 25 and ending in a eyelet 24.

Sur la plaque 3 est monté un organe primaire de manoeuvre 27 pourvu de deux fentes 28 dans lesquelles engagent des goujons de guidage 26 montés sur la plaque 3. L'organe 27 a une appendice se terminant par un goujon 29, lequel est engagé dans l'oeillet 24 de l'actionneur 23 et reçoit de ce dernier les déplacements commandés par l'actionneur. L'organe 27 est aussi pourvu d'un doigt 30 au moyen duquel il peut agir sur le même bras 14 du levier d'ouverture 12, sur lequel agit aussi le levier 16 commandant l'ouverture effectuée de l'intérieur. Enfin, l'organe primaire de manoeuvre 27 est pourvu de deux brides 31, 32 qui supportent un organe secondaire de manoeuvre 33 ayant une partie élargie 34 qui, pour un sens de mouvement, prend appui contre la bride 32. Entre la bride 31 et la partie élargie 34 est disposé un ressort 36 partiellement comprimé. Enfin, l'organe secondaire de manoeuvre 33 a une partie pliée 35 qui engage dans la fente 20 de l'organe de manoeuvre manuelle 17.On the plate 3 is mounted a primary operating member 27 provided with two slots 28 in which engage guide studs 26 mounted on the plate 3. The member 27 has an appendage ending in a stud 29, which is engaged in the eyelet 24 of the actuator 23 and receives from the latter the movements controlled by the actuator. The member 27 is also provided with a finger 30 by means of which it can act on the same arm 14 of the opening lever 12, on which the lever 16 also controls the opening effected from the inside. Finally, the primary operating member 27 is provided with two flanges 31, 32 which support a secondary operating member 33 having an enlarged portion 34 which, for a direction of movement, bears against the flange 32. Between the flange 31 and the enlarged part 34 is disposed a spring 36 partially compressed. Finally, the secondary operating member 33 has a folded part 35 which engages in the slot 20 of the manual operating member 17.

L'organe primaire de manoeuvre 27 a une position de repos (à laquelle il est reconduit par l'actionneur 23 après chaque manoeuvre) qui est celle représentée et dans laquelle le doigt 30 fait face au bras 14 du levier d'ouverture 12 sans agir sur ce dernier; les fentes 28 sont disposées d'une façon telle que, à partir de cette position de repos, elles autorisent l'organe primaire de manoeuvre 27: à se déplacer dans un sens (le sens d'ouverture) de sorte que le doigt 30 agit sur le bras 14 du levier d'ouverture 12 pour une longue course, suffisante pour donner lieu à la rétraction du verrou 9 et donc à l'ouverture de la serrure et de la porte: ainsi qu'à se déplacer aussi dans le sens opposé pour une courte course, correspondante à la course opérationnelle de l'organe de manoeuvre manuelle 17. La partie pliée 35 de l'organe secondaire de manoeuvre 33 est disposée d'une façon telle que, dans cette position de repos de l'organe primaire de manoeuvre et si l'organe de manoeuvre manuelle est en position de condamnation (comme représenté), la partie pliée 35 se trouve à proximité de l'extrémité extérieure de la fente 20 de l'organe de manoeuvre manuelle 17.The primary operating member 27 has a rest position (to which it is renewed by the actuator 23 after each operation) which is that shown and in which the finger 30 faces the arm 14 of the opening lever 12 without acting on the latter; the slots 28 are arranged in such a way that, from this rest position, they allow the primary operating member 27: to move in one direction (the opening direction) so that the finger 30 acts on the arm 14 of the opening lever 12 for a long stroke, sufficient to give rise to the retraction of the lock 9 and therefore to the opening of the lock and of the door: as well as to move also in the opposite direction for a short stroke, corresponding to the operational stroke of the manual operating member 17. The folded part 35 of the secondary operating member 33 is arranged in such a way that, in this position of rest of the primary member of operation and if the manual operation member is in the locked position (as shown), the folded part 35 is located near the outer end of the slot 20 of the manual operation member 17.

Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.

A partir de la condition représentée, de repos avec condamnation de la serrure, une commande manuelle des leviers d'ouverture n'aurait aucun effet, car le bras 15 du levier d'ouverture 12 ne fait pas face à l'extrémité pliée 18 de l'organe de manoeuvre manuelle 17. Ce dernier, au contraire, peut être déplacé manuellement jusqu'à la position de décondamnation, en agissant sur le levier 21, après quoi l'ouverture manuelle devient possible; l'extension de la fente 20 engagée avec la partie pliée 35 de l'organe secondaire de manoeuvre autorise ce déplacement de l'organe de manouvre manuelle. Toujours à partir de ladite condition de repos, l'actionneur 23 pourrait (inutilement, par inadvertance, parce qu'il s'agit d'une opération sans effet) être actionné de façon à déplacer l'organe primaire de manoeuvre 27 dans le sens opposé au sens d'ouverture; dans ce cas, la partie pliée 35 de l'organe secondaire de manoeuvre 33 se limiterait à parcourir, sans effet, la longueur de la fente 20 de l'organe de manoeuvre manuelle 17. Si, au contraire, au moment de l'actionnement de l'actionneur 23 l'organe de manoeuvre manuelle se trouve dans la position de décondamnation, il est déplacé jusqu'à la position de condamnation, sous l'action de la partie pliée 35 de l'organe secondaire de manoeuvre 33. La condamnation de la serrure peut donc toujours être effectuée, soit manuellement, soit à l'aide de l'actionneur 23.From the condition shown, of rest with condemnation of the lock, manual control of the opening levers would have no effect, since the arm 15 of the opening lever 12 does not face the folded end 18 of the manual operating member 17. The latter, on the contrary, can be moved manually to the unlocking position, by acting on the lever 21, after which the manual opening becomes possible; the extension of the slot 20 engaged with the folded part 35 of the secondary operating member allows this movement of the manual operating member. Still from said rest condition, the actuator 23 could (unnecessarily, inadvertently, because it is an ineffective operation) be actuated so as to move the primary operating member 27 in the opposite direction to the opening direction; in this case, the folded part 35 of the secondary operating member 33 would be limited to traversing, without effect, the length of the slot 20 of the manual operating member 17. If, on the contrary, at the time of actuation from the actuator 23 the manual operating member is in the unlocked position, it is moved to the locked position, under the action of the folded part 35 of the secondary operating member 33. The locking the lock can therefore always be carried out, either manually or using the actuator 23.

A partir de la condition illustrée de repos avec condamnation, l'actionneur 23 peut, au contraire, être actionné dans le sens qui déplace l'organe primaire de manoeuvre 27 dans le sens d'ouverture, et pour une amplitude correspondante à la course de l'organe de manoeuvre manuelle 17: dans ce cas, la partie pliée 35 de l'organe secondaire de manoeuvre 33 entraîne avec soi l'organe de manoeuvre manuelle 17 en le conduisant à la condition de décondamnation. Par contre, le doigt 30, même s'il fait déplacer le levier d'ouverture 12, ne se déplace pas sur une course suffisante pour donner lieu à l'ouverture. Si, par contre, au moment de l'actionnement de l'actionneur 23 l'organe de manoeuvre manuelle se trouve déjà dans la position de décondamnation, la partie pliée 35 de l'organe secondaire de manoeuvre 33 se limite à parcourir, sans effet, la longueur de la fente 20 de l'organe de manoeuvre manuelle 17. De ce fait, la décondamnation de la serrure peut toujours être effectuée, soit manuellement, soit au moyen de l'actionneur 23.Starting from the illustrated condition of rest with condemnation, the actuator 23 can, on the contrary, be actuated in the direction which displaces the primary operating member 27 in the opening direction, and for an amplitude corresponding to the stroke of the manual operating member 17: in this case, the folded part 35 of the secondary operating member 33 carries with it the manual operating member 17 leading it to the unlocked condition. On the other hand, the finger 30, even if it moves the opening lever 12, does not move over a stroke sufficient to give rise to the opening. If, on the other hand, when the actuator 23 is actuated, the manual operating member is already in the unlocked position, the folded part 35 of the secondary operating member 33 is limited to traversing, without effect. , the length of the slot 20 of the manual operating member 17. Therefore, the unlocking of the lock can always be carried out, either manually, or by means of the actuator 23.

Enfin, à partir de la condition illustrée, de repos avec condamnation, l'actionneur 23 peut être actionné dans le sens qui déplace l'organe primaire de manoeuvre 27 dans le sens d'ouverture, et pour une amplitude correspondante à la course du levier d'ouverture 12: dans ce cas, dans la première partie de la course de l'organe primaire de manoeuvre 27, la partie pliée 35 de l'organe secondaire de manoeuvre 33 réalise l'opération, mentionnée auparavant, de porter l'organe de manoeuvre manuelle 17 jusqu'à la position de décondamnation, s'il ne s'y trouve pas déjà, après quoi son contact avec l'extrémité extérieure de la fente 20 empêche un déplacement ultérieur de l'organe secondaire de manoeuvre 33. Cependant, la course ultérieure de l'organe primaire de manoeuvre 27 n'est pas empêchée, car les brides 31 et 32 peuvent glisser sur l'organe secondaire de manoeuvre 33 désormais immobile, en chargeant le ressort 36. Par conséquent, le levier d'ouverture 12 peut être déplacé le long de toute sa course, en donnant ainsi lieu à l'ouverture de la serrure et de la porte. Comme déjà dit auparavant, l'actionneur 23 est prédisposé pour reconduire toujours l'organe primaire de manoeuvre 27 à sa position de repos après chaque manoeuvre, et en cette circonstance le ressort 36 se dècharge de nouveau et l'organe secondaire de manoeuvre 33 reprend sa position initiale par rapport à l'organe primaire de manoeuvre 27.Finally, from the illustrated condition, of rest with condemnation, the actuator 23 can be actuated in the direction which displaces the primary operating member 27 in the opening direction, and for an amplitude corresponding to the stroke of the lever. opening 12: in this case, in the first part of the stroke of the primary operating member 27, the folded part 35 of the secondary operating member 33 performs the operation, mentioned above, of bringing the manual operating member 17 to the unlocked position, if it is not already there, after which its contact with the outer end of the slot 20 prevents subsequent displacement of the secondary operating member 33. However, the subsequent stroke of the primary operating member 27 is not prevented, since the flanges 31 and 32 can slide on the secondary operating member 33 which is now stationary, by loading the spring 36. Consequently, the opening lever 12 can be moved along its entire stroke, thereby giving rise to the opening of the lock and of the door. As already said before, the actuator 23 is predisposed to always return the primary operating member 27 to its rest position after each operation, and in this circumstance the spring 36 unloads again and the secondary operating member 33 resumes its initial position relative to the primary operating member 27.

Par conséquent, avec référence au schéma illustré dans le figura 6, l'actionneur peut effectuer, à partir de la position de repos indiquée par R, une courte course dans un sens (F1) jusqu'à une position (B) de condamnation de la serrure, en retournant ensuite (F2) à la position de repos R; ou bien il peut effectuer, toujour à partir de la position de repos R, une courte course dans le sens opposé (F2) jusqu'à une position (S) de décondamnation de la serrure, en retournant ensuite (F4) à la position de repos R; ou bien, enfin, l'actionneur peut effectuer, à partir de la position de repos R, une longue course (F5) dans le dernier sens mentionné, jusqu'à una position (A) d'ouverture de la serrure et de la porte, en retournant ensuite (F4) à la position de repos R.Consequently, with reference to the diagram illustrated in FIG. 6, the actuator can carry out, from the rest position indicated by R, a short stroke in one direction (F1) to a position (B) for locking the lock, then returning (F2) to the rest position R; or else it can carry out, always from the rest position R, a short stroke in the opposite direction (F2) to a position (S) unlocking the lock, then returning (F4) to the position of rest R; or, finally, the actuator can carry out, from the rest position R, a long stroke (F5) in the last direction mentioned, up to a position (A) for opening the lock and the door , then returning (F4) to the rest position R.

L'actionneur 23 peut comprendre, comme il ressort particulièrement de la figure 4, un moteur électrique 37 avec un pignon 38 qui, à travers une chaîne de plusieurs engrenages de démultiplication 40 (necessaires pour obtenir la force relativement élevée nécessaire pour actionner le levier d'ouverture 12), commande une roue dentée 41 engrenant avec une crémaillere 42 qui fait partie d'une tige 43 se terminant par l'oeillet 24 déjà mentionné. Avantageusement, l'actionneur comprend aussi un électroaimant 46, inséré électriquement en parallèle au moteur 37, et disposé pour éloigner d'un tambour 39, supporté par l'axe du moteur 37, un patin de freinage 45 (figure 5) qui normalement est poussé par un ressort 47 à freiner le tambour 39. Cette disposition sert à assurer un arrêt rapide du moteur 37, et donc de la tige 42, lorsque l'alimentation électrique est interrompue. Sinon, la haute vitesse du moteur 37 pourrait donner lieu à une course supplémentaire de la tige 42 et, par conséquent, à une imprécision dans la position finale donnée par cette dernière à l'organe primaire de manoeuvre 27.The actuator 23 may comprise, as is particularly apparent from FIG. 4, an electric motor 37 with a pinion 38 which, through a chain of several reduction gears 40 (necessary to obtain the relatively high force necessary to actuate the lever of 'opening 12), controls a toothed wheel 41 meshing with a rack 42 which is part of a rod 43 ending in the eyelet 24 already mentioned. Advantageously, the actuator also comprises an electromagnet 46, inserted electrically in parallel with the motor 37, and arranged to move away from a drum 39, supported by the axis of the motor 37, a braking pad 45 (FIG. 5) which normally is pushed by a spring 47 to brake the drum 39. This arrangement serves to ensure a rapid stop of the motor 37, and therefore of the rod 42, when the electrical supply is interrupted. Otherwise, the high speed of the motor 37 could give rise to an additional stroke of the rod 42 and, consequently, to an imprecision in the final position given by the latter to the primary operating member 27.

Le commencement de l'alimentation électrique à l'actionneur 23 pour effectuer les différentes manoeuvres prévues peut être commandé au moyen d'un interrupteur à poussoir ou a levier de n'importe quel genre. L'interruption de l'alimentation lorsque les positions prévues ont été atteintes, et l'inversion de l'alimentation pour effectuer une course de retour, peuvent être commandées par des micro-interrupteurs coopérant avec les organes intéressés de la serrure, mais de préférence la tige 42 de l'actionneur 23 présente, dans sa partie interne, au moins une glissière profilée 44 coopérant avec des micro-interrupteurs 48 pour effectuer cette action de contrôle dans l'intérieur même de l'actionneur 23, de sorte à simplifier la structure et l'installation de l'ensemble.The start of the electrical supply to the actuator 23 for carrying out the various maneuvers provided can be controlled by means of a push-button or lever switch of any kind. The interruption of the supply when the intended positions have been reached, and the reversal of the supply for carrying out a return stroke, can be controlled by microswitches cooperating with the bodies concerned with the lock, but preferably the rod 42 of the actuator 23 has, in its internal part, at least one profiled slide 44 cooperating with microswitches 48 to perform this control action in the interior of the actuator 23, so as to simplify the structure and installation of the assembly.

Bien entendu, la série d'engrenages de démultiplication 40 pourrait être remplacée par un autre dispositif de démultiplication, par exemple par une vis sans fin.Of course, the series of reduction gears 40 could be replaced by another reduction device, for example by a worm.

On a dejà dit que des adaptations appropriées doivent être appliquées au dispositif décrit ci-dessus pour l'adapter à l'actionnement de types différents de serrures. En particulier, ces adaptations peuvent comprendre des mécanismes d'inversion du mouvement. En outre, d'autres modifications et toute substitution d'équivalents techniques peuvent être apportées dans le cadre de l'invention défini par les revendications.It has already been said that appropriate adaptations must be applied to the device described above to adapt it to the actuation of different types of locks. In particular, these adaptations may include mechanisms for reversing the movement. In addition, other modifications and any substitution of technical equivalents may be made within the scope of the invention defined by the claims.
