Abstract

The invention relates to a device for controlling a pivoting lever (42) which remains free in each of its two positions; this device comprises a fixed guide (15) having a first cam profile (21), a slide (22) having a second cam profile (38) and a support bearing (39), a screw (10) capable of being driven in both directions of rotation by an electric motor (7), a nut (11) comprising, on the one hand, a driver (12) which cooperates with the first and second cam profiles (21 and 38) and, on the other hand, two teeth (13, 14). The bearing of the driver (12) on one or other of the cam profile slopes (21, 38) causes a pivoting of the nut (11) about its axis through an angle which ensures the release of the lever from the teeth of the nut. The slide (22) cooperates with a micro-contact inserted in the electrical power supply circuit of the motor. The pivoting lever (42) controls the locking or unlocking of a motor vehicle door lock. The invention also relates to a motor vehicle door lock comprising this device. <IMAGE>

Description

La présente invention a trait à un dispositif de commande d'un levier pivotant devant être amené dans l'une ou l'autre de deux positions tout en restant libre dans chacune de ces deux positions; elle concerne également une serrure comportant ce dispositif. Un tel dispositif est, en effet, utile pour la commande de condamnation et de décondamnation d'une serrure de portière de véhicule automobile car, même lorsque cette commande est assurée électriquement, il est nécessaire de pouvoir condamner ou décondamner manuellement la serrure, de sorte que le levier qui assure la commande de condamnation à partir d'un moteur électrique doit être découplé de son entrainement pour permettre la manoeuvre manuelle.The present invention relates to a device for controlling a pivoting lever to be brought into one or the other of two positions while remaining free in each of these two positions; it also relates to a lock comprising this device. Such a device is, in fact, useful for controlling the locking and unlocking of a motor vehicle door lock because, even when this control is provided electrically, it is necessary to be able to manually lock or unlock the lock, so that the lever which provides the locking command from an electric motor must be decoupled from its drive to allow manual operation.

On sait que l'on considère maintenant comme souhaitable de commander électriquement les serrures de portière de véhicules automobiles. Pour ces serrures, la gâche est généralement constituée d'un axe porté par la carrosserie du véhicule et le pêne de la serrure a la forme d'une fourche; ce pêne est retenu en position de fermeture par un cliquet, dont la manoeuvre en rotation permet de commander l'ouverture de la serrure. Pour assurer la condamnation ou la décondamnation d'une telle serrure, on vient bloquer ou débrayer dans sa position de fermeture l'un des organes de la serrure et ce blocage ou débrayage est généralement obtenu en faisant pivoter autour d'un axe fixe de la serrure une pièce qui assure le blocage ou le débrayage. La condamnation ou la décondamnation électrique de la serrure s'obtient donc en commandant électriquement un pivotement. Mais pour le cas où il y aurait une panne de l'alimentation électrique, il faut, bien entendu, que la serrure puisse être manoeuvrée manuellement, par exemple, en agissant sur la clé associée au barillet de sûreté de la serrure: il en résulte que la pièce, qui commande électriquement le pivotement, doit nécessairement être libre aux deux extrémités de sa course, pour permettre sa manoeuvre manuelle.It is known that it is now considered desirable to electrically control the door locks of motor vehicles. For these locks, the strike generally consists of an axis carried by the vehicle body and the bolt of the lock has the form of a fork; this bolt is retained in the closed position by a pawl, the rotary operation of which allows the opening of the lock to be controlled. To ensure the locking or unlocking of such a lock, one comes to block or disengage in its closed position one of the organs of the lock and this blocking or disengaging is generally obtained by pivoting around a fixed axis of the one-piece lock that locks or disengages. The electrical locking or unlocking of the lock is therefore obtained by electrically controlling a pivoting. But in case there is a breakdown of the power supply, it is, of course, necessary that the lock can be operated manually, for example, by acting on the key associated with the safety barrel of the lock: it follows that the part, which electrically controls the pivoting, must necessarily be free at the two ends of its travel, to allow its manual operation.

En outre, les serrures de portière de véhicule sont généralement équipées d'organes de verrouillage manuel, dits "tirettes de frise", grâce auxquels on vient manuellement, de l'interieur du véhicule, mettre la serrure en position condamnée ou décondamnée. Si l'on ferme et condamne un véhicule, il est évidemment possible, en brisant la vitre de portière, d'agir sur la tirette de frise pour décondamner la serrure; on a donc imaginé de commander électriquement une inhibition de l'action de la tirette de frise sur la serrure pour que, dans un tel cas, l'auteur de l'effraction, en agissant sur la tirette de frise, ne puisse pas décondamner la serrure. Bien entendu, il faut que cette "supercondamnation" puisse être supprimée électriquement par le propriétaire du véhicule; mais il faut également, pour le cas où il y aurait une panne électrique, que le shunt de cette inhibition puisse résulter d'une action manuelle faite sur la serrure par l'intermédiaire du barillet de ladite serrure.In addition, vehicle door locks are generally equipped with manual locking members, called "frieze pulls", by means of which one comes manually, from inside the vehicle, to put the lock in the locked or unlocked position. If you close and lock a vehicle, it is obviously possible, by breaking the door window, to act on the frieze zipper to unlock the lock; it has therefore been imagined to electrically control an inhibition of the action of the frieze zipper on the lock so that, in such a case, the perpetrator, by acting on the frieze zipper, cannot unlock the lock. Of course, this "super-conviction" must be able to be removed electrically by the owner of the vehicle; but it is also necessary, in the event that there is an electrical failure, that the shunt of this inhibition may result from a manual action made on the lock by means of the barrel of said lock.

Pour réaliser toutes ces fonctions, on a déjà proposé de nombreux dispositifs, mais l'invention a pour but de proposer une réalisation, qui est à la fois particulièrement fiable et plus économique que les dispositifs antérieurs.To achieve all these functions, numerous devices have already been proposed, but the object of the invention is to propose an embodiment, which is both particularly reliable and more economical than prior devices.

La présente invention a donc pour objet un dispositif de commande d'un levier pivotant devant être amené dans l'une ou l'autre de deux positions tout en restant libre dans chacune de ces deux positions, ce dispositif comportant un système vis/écrou dont la vis est susceptible d'être entrainée dans les deux sens de rotation par un moteur électrique et dont l'écrou commande le pivotement dudit levier par appui simple contre une zone d'entraînement dudit levier, caractérisé par le fait qu'il comporte un guide fixe dans lequel est pratiqué un premier orifice dont le contour fermé constitue un premier profil de came, l'écrou du système vis/écrou comportant, d'un côté d'un plan diamétral, un entraîneur qui pénètre dans le premier orifice et coopère avec son profil de came et, de l'autre côté dudit plan diamétral, deux dents sensiblement symétriques par rapport à un axe perpendiculaire audit plan diamétral, chacune des dents pouvant venir en appui contre l'une des deux faces opposées de la zone d'entraînement du levier, le premier orifice comportant deux rainures rectilignes, dont les lignes moyennes, sensiblement parallèles à l'axe de la vis, sont décalées perpendiculairement à l'axe de ladite vis, les bordures de ces deux rainures étant reliées entre elles par deux rampes parallèles obliques par rapport aux lignes moyennes desdites rainures, l'une desdites rampes reliant les deux bordures de rainure les plus proches de l'axe de rotation du levier et l'autre reliant les deux autres bordures, l'appui de l'entraîneur sur l'une ou l'autre desdites rampes provoquant un pivotement de l'écrou autour de son axe d'un angle qui assure l'échappement de celle des dents de l'écrou, qui est en appui sur la zone d'entraînement du levier, quand l'entraîneur arrive sur ladite rampe, sans que l'autre dent vienne buter sur le levier.The present invention therefore relates to a device for controlling a pivoting lever which must be brought into one or the other of two positions while remaining free in each of these two positions, this device comprising a screw / nut system. whose screw is capable of being driven in both directions of rotation by an electric motor and whose nut controls the pivoting of said lever by simple pressing against a drive zone of said lever, characterized in that it comprises a fixed guide in which a first orifice is made, the closed contour of which constitutes a first cam profile, the nut of the screw / nut system comprising, on one side of a diametrical plane, a driver which penetrates into the first orifice and cooperates with its cam profile and, on the other side of said diametral plane, two teeth substantially symmetrical with respect to an axis perpendicular to said diametral plane, each of the teeth being able to come to bear against one of the two opposite faces of the zone of driving the lever, the first orifice comprising two rectilinear grooves, the mean lines of which, substantially parallel to the axis of the screw, are offset perpendicular to the axis of said screw, the b refuse of these two grooves being connected to each other by two parallel ramps oblique to the mean lines of said grooves, one of said ramps connecting the two groove edges closest to the axis of rotation of the lever and the other connecting the two other edges, the support of the coach on one or the other of said ramps causing the nut to pivot about its axis at an angle which ensures the escape of that of the teeth of the nut, which is in abutment on the drive zone of the lever, when the coach arrives on said ramp, without the other tooth coming up against the lever.

Selon un mode de réalisation avantageux, le premier profil de came est dispose sensiblement dans un plan parallèle à l'axe de la vis; l'entraîneur de l'écrou est un téton cylindrique; l'une au moins des positions d'arrêt de l'écrou est déterminée par un micro-contact inséré sur l'alimentation électrique du moteur et commandé, directement ou non, par la position de l'écrou.According to an advantageous embodiment, the first cam profile is arranged substantially in a plane parallel to the axis of the screw; the nut driver is a cylindrical nipple; at least one of the nut stop positions is determined by a micro-switch inserted in the motor's power supply and controlled, directly or indirectly, by the position of the nut.

Un tel dispositif de commande permet d'assurer électriquement la condamnation et la décondamnation d'une serrure. Si l'on désire, en outre, assurer une super-condamnation, il sera expliqué dans la description ultérieure, qu'il suffit, après avoir commandé la condamnation de la serrure, d'assurer la rotation d'un bras pivotant et son maintien en position, pour que cette simple rotation permette d'obtenir l'inhibition d'une action de décondamnation effectuée à partir de l'organe de verrouillage manuel dit "tirette de frise". On a donc prévu d'assurer cette fonction complémentaire avec le dispositif de commande ci-dessus défini. Dans un tel mode de réalisation, le dispositif selon l'invention comporte, en outre, un coulisseau susceptible de se déplacer en translation par rapport au guide parallèlement à l'axe de la vis, un deuxième orifice étant pratiqué dans ledit coulisseau et définissant par son contour fermé un deuxième profil de came, l'entraîneur de l'écrou pénétrant aussi dans le deuxième orifice et coopérant avec le deuxième profil de came, ce deuxième orifice comportant une rainure sensiblement rectiligne au niveau de chacune des rainures du premier orifice, les deux rainures du deuxième orifice étant, comme pour le premier orifice, reliées entre elles par des rampes obliques sensiblement parallèles à celles du premier orifice et écartées l'une de l'autre de la même distance, ledit coulisseau coopérant, à une extrémité dite "active" de sa course, avec un bras pivotant pour constituer une cale pour ledit bras, celle des rampes du coulisseau qui se trouve du côté opposé à ladite extrémité active comportant, dans sa zone de raccord avec celle des rainures du deuxième orifice où se trouve l'entraîneur pour ladite extrémité active de course, une portée d'appui permettant à l'entraîneur d'assurer la translation du coulisseau, les rampes du deuxième orifice étant légèrement décalées par rapport à celles du premier orifice pour que l'entraîneur vienne en appui sur la rampe du premier orifice quand le coulisseau est poussé vers l'extrémité dite "inactive" de sa course, la longueur de la rainure du premier orifice située du côté de l'extrémité active de la course du coulisseau étant supérieure à celle de la rainure correspondante du deuxième orifice.Such a control device electrically ensures the locking and unlocking of a lock. If one wishes, moreover, to ensure a super-locking, it will be explained in the subsequent description, that it suffices, after having ordered the locking of the lock, to ensure the rotation of a pivoting arm and its maintenance in position, so that this simple rotation makes it possible to obtain the inhibition of an unlocking action carried out from the manual locking member known as a "frieze pull tab". Provision has therefore been made to provide this additional function with the control device defined above. In such an embodiment, the device according to the invention further comprises a slide capable of moving in translation relative to the guide parallel to the axis of the screw, a second orifice being formed in said slide and defining by its closed contour a second cam profile, the nut driver also entering the second orifice and cooperating with the second cam profile, this second orifice comprising a substantially rectilinear groove at each of the grooves in the first orifice, the two grooves of the second orifice being, as for the first orifice, connected to each other by oblique ramps substantially parallel to those of the first orifice and spaced from one another by the same distance, said slide cooperating, at one end called " active "of its stroke, with a pivoting arm to constitute a wedge for said arm, that of the ramps of the slide which is on the opposite side at said active end comprising, in its zone of connection with that of grooves of the second orifice where the coach is located for said active end of travel, a bearing surface allowing the coach to ensure the translation of the slide, the ramps of the second orifice being slightly offset from those of the first orifice so that the trainer comes to bear on the ramp of the first orifice when the slide is pushed towards the so-called "inactive" end of its travel, the length of the groove of the first orifice located on the side of the active end of the travel of the slide being greater than that of the corresponding groove of the second orifice.

Dans un mode de réalisation avantageux, les longueurs des rainures des premier et deuxième orifices situées du côte de l'extrémité inactive de la course du coulisseau sont voisines; à l'extrémité inactive de sa course, le coulisseau coopère avec un micro-contact inséré sur l'alimentation électrique du moteur; le coulisseau comporte un frein coopérant avec le bâti pour arrêter sa translation rapidement après la coupure de l'alimentation électrique du moteur.In an advantageous embodiment, the lengths of the grooves of the first and second orifices located on the side of the inactive end of the travel of the slide are close; at the inactive end of its travel, the slide cooperates with a micro-contact inserted on the electrical supply of the motor; the slide comprises a brake cooperating with the frame to stop its translation quickly after the power supply to the engine is cut off.

On peut prévoir que le bras pivotant du dispositif qui vient d'être décrit agisse sur un élément d'un mécanisme qui assure la condamnation ou la décondamnation d'une serrure de portière de véhicule automobile comportant un barillet à clé, ledit élément coopérant avec un organe de verrouillage manuel, le bras pivotant, lorsque le coulisseau vient à l'extrémité active de sa course, amenant par son mouvement ledit élément dans une position où l'organe de verrouillage manuel ne peut plus coopérer avec lui, la décondamnation de la serrure ne pouvant alors intervenir que par l'action du barillet de ladite serrure sur le mécanisme.Provision may be made for the pivoting arm of the device which has just been described to act on an element of a mechanism which ensures the locking or unlocking of a motor vehicle door lock comprising a key cylinder, said element cooperating with a manual locking member, the pivoting arm, when the slider comes to the active end of its travel, bringing its movement through said element into a position where the manual locking member can no longer cooperate with it, unlocking the lock can then only intervene by the action of the barrel of said lock on the mechanism.

On peut aussi prévoir que le levier pivotant du dispositif ci-dessus défini commande la condamnation ou la décondamnation d'une serrure de portière de véhicule automobile.It can also be provided that the pivoting lever of the above defined device controls the locking or unlocking of a motor vehicle door lock.

Le dispositif selon l'invention peut avantageusement être utilisé en combinaison avec un mécanisme de débrayage de l'organe de verrouillage manuel associé à une serrure de portière de véhicule automobile et disposé sur la face intérieure de ladite portière, ladite serrure pouvant prendre soit une configuration "condamnée" où la manoeuvre extérieure est impossible, soit une configuration "décondamnée" dans laquelle la serrure peut être manoeuvrée aussi bien de l'extérieur que de l'intérieur du véhicule, le passage d'une configuration à l'autre s'effectuant par rotation d'une platine autour d'un axe fixe de la serrure, ladite platine étant commandée par au moins un organe de manoeuvre manuel distinct de l'organe de verrouillage manuel précité, ledit organe de verrouillage manuel ne pouvant prendre que deux positions, l'une dans laquelle il met la platine en position décondamnée et l'autre dans laquelle il la met en position condamnée, l'action de l'organe de verrouillage sur la platine pouvant être inhibée quand la platine est en position "condamnée". Dans un tel mécanisme de débrayage, l'organe de verrouillage a une extrémité active, qui coopère avec un équipage coulissant susceptible d'une translation libre par rapport à la platine, ledit équipage comportant une rainure-glissière, où se déplace l'extrémité d'un poussoir susceptible de pivoter autour d'un axe fixe de la serrure, ledit équipage étant soumis à l'action d'un ressort de rappel qui le force vers une première extrémité de sa course, alors que le pivotement du poussoir peut l'amener vers la deuxième activité de sa course de translation, ledit équipage coulissant comportant une fenêtre traversée par l'extrémité active de l'organe de verrouillage, ladite fenêtre comportant côte-à-côte deux zones, la première, de faible longueur, où se trouve l'extrémité active de l'organe de verrouillage quand l'équipage coulissant est à la première extrémité de sa course, la deuxième, de plus grande longueur, où se trouve l'extrémité active de l'organe de verrouillage quand l'équipage coulissant est à la deuxième extrémité de sa course, la longueur de cette deuxième zone étant suffisante pour que la manoeuvre manuelle de l'organe de verrouillage n'entraîne aucun contact efficace entre l'organe de verrouillage et l'équipage coulissant, alors que la longueur de la première zone est suffisamment faible pour que la manoeuvre manuelle de l'organe de verrouillage entraîne une rotation de la platine et son passage de la position de condamnation à la position de décondamnation ou inversement.The device according to the invention can advantageously be used in combination with a mechanism for disengaging the manual locking member associated with a door lock of a motor vehicle and arranged on the interior face of said door, said lock being able to take either a configuration "locked" where exterior operation is impossible, ie a "unlocked" configuration in which the lock can be operated both from outside and from inside the vehicle, the passage from one configuration to the other taking place by rotation of a plate around a fixed axis of the lock, said plate being controlled by at least one manual operating member distinct from the abovementioned manual locking member, said manual locking member being able to assume only two positions, one in which he puts the plate in the unlocked position and the other in which he puts it in the locked position, the action of the locking on the plate which can be inhibited when the plate is in the "locked" position. In such a declutching mechanism, the locking member has an active end, which cooperates with a sliding element capable of free translation relative to the plate, said element comprising a groove-slide, where the end moves. 'A pusher capable of pivoting about a fixed axis of the lock, said assembly being subjected to the action of a return spring which forces it towards a first end of its travel, while the pivoting of the pusher can lead to the second activity of its translational stroke, said sliding assembly comprising a window crossed by the active end of the locking member, said window comprising two zones side by side, the first, of short length, where the active end of the locking member is located when the sliding assembly is at the first end of its stroke, the second, of greater length, where the active end of the locking member is located when the sliding assembly is at the second end of its stroke, the length of this second zone being sufficient for manual operation of the locking member does not cause any effective contact between the locking member and the sliding assembly, while the length of the first zone is small enough that the manual operation of the locking member causes a rotation of the plate and its passage from the locking position to the unlocking position or vice versa.

Dans un mode de réalisation préféré de ce mécanisme de débrayage, la platine est solidaire d'un moyen qui assure sa commande électriquement; l'organe de manoeuvre manuelle de la platine est le barillet de sûreté de la serrure; l'équipage coulissant a une forme rectangulaire et se déplace en translation entre deux prolongements parallèles de la platine; la fenêtre de l'équipement coulissant est constituée de deux zones rectangulaires accolées ayant sensiblement la même largeur, les petits côtés de ces rectangles étant sensiblement parallèles au prolongement de la platine; la rainure-glissière comporte une bordure rectiligne parallèle aux longueurs des deux zones de fenêtre et une bordure circulaire centrée sur l'axe de pivotement de la platine; l'extrémité du poussoir est sensiblement circulaire et a un diamètre sensiblement égal à la distance minimum entre les deux bordures de la rainure-glissière.In a preferred embodiment of this declutching mechanism, the plate is secured to a means which ensures its control electrically; the manual operating member of the plate is the safety barrel of the lock; the sliding assembly has a rectangular shape and moves in translation between two parallel extensions of the plate; the sliding equipment window consists of two contiguous rectangular zones having substantially the same width, the short sides of these rectangles being substantially parallel to the extension of the plate; the groove-slide has a rectilinear border parallel to the lengths of the two window zones and a circular border centered on the pivot axis of the plate; the end of the pusher is substantially circular and has a diameter substantially equal to the minimum distance between the two edges of the groove-slide.

Bien entendu, l'invention a également pour objet une serrure de portière de véhicule automobile comportant un dispositif de commande à écrou basculant tel que ci-dessus défini.Of course, the invention also has for subject a motor vehicle door lock comprising a tilting nut control device as defined above.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire maintenant, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the invention, we will now describe, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawing.

En se référant au dessin, on voit que la serrure est contenue dans un boîtier 1, dont le plan moyen est dispose sensiblement parallèle au plan de la portière sur laquelle est fixée la serrure. Le boîtier 1, parallèlépipèdique, est constitué d'une face avant 2, d'une face arrière 3 sensiblement parallèle à la face avant 2, d'une face latérale droite 4, d'une face latérale gauche 5 sensiblement parallèle à la face latérale droite 4, et d'une face supérieure 6. Le plan de coupe I-I est un plan vertical. Pour simplifier la description, on supposera que la serrure décrite est logée dans un boîter 1 vertical, dont la face 6 est la face supérieure.Referring to the drawing, it can be seen that the lock is contained in a housing 1, the mean plane of which is arranged substantially parallel to the plane of the door on which the lock is fixed. The box 1, parallelepipedal, consists of a front face 2, a rear face 3 substantially parallel to the front face 2, a right side face 4, a left side face 5 substantially parallel to the side face straight line 4, and an upper face 6. The section plane II is a vertical plane. To simplify the description, it will be assumed that the lock described is housed in a vertical box 1, the face 6 of which is the upper face.

La serrure selon l'invention comporte un dispositif de commande électrique constitué d'un moteur électrique 7 muni d'un pignon 8, qui engrène sur une roue dentée 9 pour constituer un réducteur. L'axe B de la roue dentée 9 est une vis 10 munie d'un écrou 11.The lock according to the invention comprises an electrical control device consisting of an electric motor 7 provided with a pinion 8, which meshes on a toothed wheel 9 to constitute a reduction gear. The axis B of the toothed wheel 9 is a screw 10 provided with a nut 11.

L'écrou 11, de forme cylindrique, comporte sur sa surface externe, d'un côté d'un plan diamétral P, un entraîneur 12 et de l'autre côté dudit plan P, deux dents 13 et 14 sensiblement symétriques par rapport à un axe A perpendiculaire audit plan P comme le montre la figure 3. L'entraîneur 12 de l'écrou 11 est un téton cylindrique. Les dents 13, 14 sont délimitées respectivement par deux faces 131, 132; 141, 142 perpendiculaires au plan P et perpendiculaires à l'axe B, une face 133, 143 perpendiculaire au plan P et parallèle au plan contenant l'axe A et l'axe B, et une face oblique 134; 144. L'extrémité de chacune des dents 13, 14 est limitée par une face 135, 145 perpendiculaire à l'axe A. Les dents 13, 14 sont solidaires du cylindre de l'écrou 11.The nut 11, of cylindrical shape, comprises on its external surface, on one side of a diametrical plane P, a driver 12 and on the other side of said plane P, two teeth 13 and 14 substantially symmetrical with respect to a axis A perpendicular to said plane P as shown in Figure 3. The driver 12 of the nut 11 is a cylindrical stud. The teeth 13, 14 are delimited respectively by two faces 131, 132; 141, 142 perpendicular to the plane P and perpendicular to the axis B, a face 133, 143 perpendicular to the plane P and parallel to the plane containing the axis A and the axis B, and an oblique face 134; 144. The extremity of each of the teeth 13, 14 is limited by a face 135, 145 perpendicular to the axis A. The teeth 13, 14 are integral with the cylinder of nut 11.

Le dispositif de commande comporte aussi un guide 15 fixe porté par le boîtier. Les sommets du guide 15 définissent un rectangle (figure 3). Dans le guide 15 est pratiqué un orifice 16, dit "premier orifice", comprenant une rainure supérieure 17, une rainure inférieure 18 et deux rampes 19, 20. Les lignes moyennes des deux rainures 17, 18 rectilignes sont sensiblement parallèles à l'axe B de la vis et sont décalées perpendiculairement à cet axe B. Les bordures des deux rainures 17, 18 sont reliées entre elles par deux rampes 19, 20 parallèles, obliques par rapport aux lignes moyennes desdites rainures. La rampe 19 relie la bordure inférieure de la rainure supérieure 17 et la bordure inférieure de la rainure inferieure 18. La rampe 20 relie la bordure supérieure de la rainure supérieure 17 et la bordure supérieure de la rainure inférieure 18. Le bord du premier orifice 16 sert de profil de came pour l'entraîneur 12, qui vient s'appuyer dessus: le contour fermé de ce premier orifice 16 constitue un premier profil de came 21. Le premier profil de came 21 est disposé sensiblement dans un plan parallèle à l'axe B de la vis. La face du guide 15, vis-à-vis de l'écrou 11, est creusée de sorte que, lorsque l'écrou se loge dans le creux, l'axe B de la vis se rapproche de la face arrière 3 du boîtier 1. L'entraîneur 12 pénètre dans le premier profil de came 21, comme le montre la figure 2.The control device also includes a fixed guide 15 carried by the housing. The vertices of the guide 15 define a rectangle (Figure 3). In the guide 15 is made an orifice 16, called "first orifice", comprising an upper groove 17, a lower groove 18 and two ramps 19, 20. The mean lines of the two rectilinear grooves 17, 18 are substantially parallel to the axis B of the screw and are offset perpendicular to this axis B. The edges of the two grooves 17, 18 are interconnected by two ramps 19, 20 parallel, oblique to the midlines of said grooves. The ramp 19 connects the lower edge of the upper groove 17 and the lower edge of the lower groove 18. The ramp 20 connects the upper edge of the upper groove 17 and the upper edge of the lower groove 18. The edge of the first orifice 16 serves as a cam profile for the driver 12, which comes to rest on it: the closed contour of this first orifice 16 constitutes a first cam profile 21. The first cam profile 21 is disposed substantially in a plane parallel to the axis B of the screw. The face of the guide 15, opposite the nut 11, is hollowed out so that, when the nut is housed in the recess, the axis B of the screw approaches the rear face 3 of the housing 1 The driver 12 enters the first cam profile 21, as shown in FIG. 2.

Le dispositif comprend également un coulisseau 22 (figure 3). Le coulisseau 22 est constitué d'un parallèlépipède rectangle délimité par une face avant 220, une face arrière 221, un côté latéral droit 222, un côté latéral gauche 223, un côté supérieur 224 et un côté inférieur 225. Le côté supérieur 224 comporte à son extrémité gauche deux paliers décalés 29, 30. Une patte 31 se trouve sur le côté inférieur 225, solidaire du parallèlépipède rectangle. La patte 31 est un parallèlépipède rectangle dont le grand axe est perpendiculaire à la face avant 220 du coulisseau 22. Un deuxième orifice 32 est pratiqué dans le coulisseau 22. Le deuxième orifice 32 comporte une rainure supérieure 33 terminée à son extrémité gauche (sur la figure 3) par une butée 34 et une rainure inférieure 35. Les rainures 33 et 35 sont rectilignes et sensiblement au niveau de chacune des rainures 17, 18 du premier orifice 16. Dans le deuxième orifice 32, une rampe 36 relie le bord inférieur de la rainure supérieure 33 et le bord inférieur de la rainure inférieure 35; une rampe 37 relie le bord de la butée 34 et le bord supérieur de la rainure inférieure 35. Les rampes 36, 37 sont obliques, sensiblement parallèles aux rampes 19, 20 du premier orifice 16 et écartées l'une de l'autre de la même distance; elles sont légèrement décalées par rapport aux rampes 19, 20 du premier orifice 16 dans le sens de la ligne moyenne des rainures. La rainure supérieure 17 du premier orifice 16 est plus longue que la rainure supérieure 33 du deuxième orifice 32. Le bord du deuxième orifice 32 sert également de profil de came pour l'entraîneur 12 qui vient s'appuyer dessus: le contour fermé de ce deuxième orifice 32 constitue un deuxième profil de came 38. Le coulisseau 22 comporte également une portée d'appui 39 solidaire par sa base de la face avant 220. Un côte de la portée 39 est au droit du côte latéral 222; le côte opposé est au droit du fond de la rainure 33. Le coulisseau 22 possède, sur son côté supérieur 224, un frein 40 (figure 3). La face avant 220 du coulisseau 22 est parallèle à la face arrière du guide 15 et en contact avec elle. La portée d'appui 39 du coulisseau 22 pénètre dans la rainure supérieure 17 du premier orifice 16 du guide 15. Le guide 15 et l'écrou 11 se situent au-dessus de la patte 31.The device also includes a slide 22 (Figure 3). The slide 22 consists of a rectangular parallelepiped delimited by a front face 220, a rear face 221, a right lateral side 222, a left lateral side 223, an upper side 224 and a lower side 225. The upper side 224 has at its left end two offset bearings 29, 30. A tab 31 is located on the lower side 225, integral with the rectangular parallelepiped. The tab 31 is a rectangular parallelepiped whose major axis is perpendicular to the front face 220 of the slide 22. A second hole 32 is made in the slide 22. The second hole 32 has an upper groove 33 terminated at its left end (on the Figure 3) by a stop 34 and a lower groove 35. The grooves 33 and 35 are rectilinear and substantially at each of the grooves 17, 18 of the first orifice 16. In the second orifice 32, a ramp 36 connects the lower edge of the upper groove 33 and the lower edge of the lower groove 35; a ramp 37 connects the edge of the stop 34 and the upper edge of the lower groove 35. The ramps 36, 37 are oblique, substantially parallel to the ramps 19, 20 of the first orifice 16 and spaced from one another from the same distance; they are slightly offset from the ramps 19, 20 of the first orifice 16 in the direction of the mean line of the grooves. The upper groove 17 of the first orifice 16 is longer than the upper groove 33 of the second orifice 32. The edge of the second orifice 32 also serves as a cam profile for the driver 12 which comes to bear on it: the closed outline of this second orifice 32 constitutes a second cam profile 38. The slide 22 also includes a bearing surface 39 secured by its base to the front face 220. A side of the range 39 is in line with the lateral side 222; the opposite side is to the right of the bottom of the groove 33. The slide 22 has, on its upper side 224, a brake 40 (Figure 3). The front face 220 of the slide 22 is parallel to the rear face of the guide 15 and in contact with it. The bearing surface 39 of the slide 22 enters the upper groove 17 of the first orifice 16 of the guide 15. The guide 15 and the nut 11 are located above the tab 31.

Le dispositif de commande comprend également un micro-contact 41 inséré sur l'alimentation électrique du moteur 7 et fixé à l'intérieur du boîtier 1 de façon à coopérer avec les paliers décalés 29 et 30 du coulisseau 22.The control device also comprises a microswitch 41 inserted on the electrical supply of the motor 7 and fixed inside the housing 1 so as to cooperate with the offset bearings 29 and 30 of the slide 22.

Le dispositif de commande électrique, qui vient d'être décrit, est destiné, dans la serrure selon l'invention, à manoeuvrer un dispositif de condamnation simple des organes de fermeture de la serrure et un dispositif de super-condamnation. Ces deux fonctions doivent, bien entendu, être assurées de façon réversible pour que l'utilisateur puisse décondamner électriquement un véhicule dont il a condamné l'accès. Mais, en outre, la décondamnation doit pouvoir être assurée manuellement pour le cas où il y aurait une panne électrique. On va décrire, ci-après, les mécanismes qui assurent ces deux fonctions, les organes de fermeture proprement dit n'étant pas décrits et étant ceux de l'état de la technique, à savoir: un pêne pivotant en forme de fourche et un cliquet pivotant apte à retenir le pêne dans une position, où la gâche portée par la carrosserie du véhicule, est maintenue entre les deux dents du pêne.The electrical control device, which has just been described, is intended, in the lock according to the invention, to operate a simple device for locking the locking members of the lock and a super-locking device. These two functions must, of course, be provided in a reversible manner so that the user can electrically unlock a vehicle to which he has blocked access. However, in addition, unlocking must be able to be carried out manually in the event of an electrical failure. We will describe, below, the mechanisms which perform these two functions, the closure members proper not being described and being those of the state of the art, namely: a swivel bolt in the form of a fork and a pivoting pawl capable of retaining the bolt in a position, where the keeper carried by the vehicle body is held between the two teeth of the bolt.

Le dispositif de condamnation simple comprend un levier 42 fixé à une platine 44 par un arbre 43 dont l'axe est fixe dans la serrure. Comme on le voit sur la figure 2, le levier 42 comporte un retour en équerre 420 parallèle à l'axe de l'arbre 43; le levier 42 est sensiblement plan et il est disposé parallèlement aux faces 2 et 3 du boîtier. La platine 44 possède un orifice 45 et deux prolongements 46 disposés de part et d'autre de l'arbre 43. Le plan moyen de la platine 44 est parallèle à la face avant 2 du boîtier 1.The simple locking device comprises a lever 42 fixed to a plate 44 by a shaft 43 whose axis is fixed in the lock. As can be seen in FIG. 2, the lever 42 has a square return 420 parallel to the axis of the shaft 43; the lever 42 is substantially planar and it is arranged parallel to the faces 2 and 3 of the housing. The plate 44 has an orifice 45 and two extensions 46 arranged on either side of the shaft 43. The mean plane of the plate 44 is parallel to the front face 2 of the housing 1.

Le dispositif de super-condamnation comprend un bras 47 relié à un poussoir 48 par un arbre 49, dont l'axe est fixe dans la serrure; le poussoir 48 coopère avec une coulisse 50 portée par la platine 44.The super-locking device comprises an arm 47 connected to a pusher 48 by a shaft 49, the axis of which is fixed in the lock; the pusher 48 cooperates with a slide 50 carried by the plate 44.

La coulisse 50 est de forme sensiblement rectangulaire: son petit côté est parallèle à la longueur des prolongements 46 de la platine 44 (figure 1). La coulisse 50 est située entre les deux prolongements 46, qui lui servent de glissières; elle présente une fenêtre 51 constituée de deux zones rectangulaires ayant sensiblement la même largeur, les petits côtés étant sensiblement parallèles aux prolongements 46 de la platine 44. La zone la plus proche de l'arbre 43 a une longueur supérieure à celle de l'autre zone; les deux petits côtés les plus proches de l'axe B sont dans le prolongement l'un de l'autre. Une extrémité de tirette de frise 55 vient se loger dans la fenêtre 51. La coulisse 50 comporte également une rainure-glissière 52 délimitée par une bordure rectiligne 53, sensiblement perpendiculaire aux prolongements 46 de la platine 44, et par une bordure circulaire 54 centrée sur l'axe de l'arbre 43 de la platine 44.The slide 50 is of substantially rectangular shape: its short side is parallel to the length of the extensions 46 of the plate 44 (Figure 1). The slide 50 is located between the two extensions 46, which serve as slides; it has a window 51 consisting of two rectangular zones having substantially the same width, the short sides being substantially parallel to the extensions 46 of the plate 44. The zone closest to the shaft 43 has a length greater than that of the other zoned; the two short sides closest to the B axis are in line with one another. A frieze zipper end 55 is housed in the window 51. The slide 50 also includes a groove-slide 52 delimited by a straight edge 53, substantially perpendicular to the extensions 46 of the plate 44, and by a circular edge 54 centered on the axis of the shaft 43 of the plate 44.

Le bras 47 et le poussoir 48 sont sensiblement parallèles à la face avant 2 du boîtier 1. Le poussoir 48 est soumis à l'action d'un ressort de rappel, qui est schématisé par le ressort 56 des figures 14 à 17. Le poussoir 48 a une extrémité arrondie, dont le diamètre correspond sensiblement à la largeur minimum de la rainure-glissière 52 et qui est logé dans ladite rainure-glissière 52.The arm 47 and the pusher 48 are substantially parallel to the front face 2 of the housing 1. The pusher 48 is subjected to the action of a return spring, which is shown diagrammatically by the spring 56 in FIGS. 14 to 17. The pusher 48 has a rounded end, the diameter of which corresponds substantially to the minimum width of the groove-slide 52 and which is housed in said groove-slide 52.

On va expliquer, ci-après, le fonctionnement de la serrure qui vient d'être décrite.We will explain, below, the operation of the lock which has just been described.

Sur la figure 7, la serrure est représentée en position de décondamnation. Le levier 42 est à la première extrémité de sa course. Le coulisseau 22 est en position telle que le deuxième profil de came 38 est presqu'au droit du premier profil de came 21. L'entraîneur 12 de l'écrou 11 se situe à l'extrémité gauche des rainures inférieures 18, 35. L'écrou 11 se trouve basculé vers le haut, comme le montre la figure 4. Le palier 29 du coulisseau 22 est en contact avec le micro-contact 41. La platine 44 est à une première extrémité de sa course correspondant à la décondamnation.In Figure 7, the lock is shown in the unlocked position. The lever 42 is at the first end of its travel. The slide 22 is in position such that the second cam profile 38 is almost to the right of the first cam profile 21. The driver 12 of the nut 11 is located at the left end of the lower grooves 18, 35. The nut 11 is is tilted upwards, as shown in FIG. 4. The bearing 29 of the slide 22 is in contact with the micro-contact 41. The plate 44 is at a first end of its travel corresponding to the unlocking.

Lorsque la condamnation de la serrure est commandée électriquement, par exemple, par une commande infrarouge, le moteur électrique 7 est alimenté. Le moteur électrique 7 met en rotation le pignon 8 dont le mouvement de rotation est transmis à la vis 10 par la roue dentée 9. La rotation de la vis 10 provoque le déplacement de l'écrou 11 vers la droite, parallèlement à l'axe B, comme l'indique la flèche de la figure 8. L'écrou 11 entre en contact, par la face 131 de la dent 13, avec le retour en équerre 420 du levier 42. L'écrou 11 entraîne, pendant sa translation, le levier 42 qui pivote autour de l'axe de l'arbre 43. Pendant la translation illustrée par le passage de la figure 7 à la figure 8, l'entraîneur 12 de l'écrou 11 longe la bordure inférieure des rainures inférieures 18, 35, de sorte que l'écrou 11 reste basculé vers le haut, comme sur la figure 4. Lorsque l'entraîneur 12 se trouve à l'extrémité droite des rainures inférieures 18, 35, comme le montre la figure 8, le levier 42 a subi la rotation nécessaire pour faire basculer la platine 44 autour de l'arbre 43, dans la direction qui l'amène vers la deuxième extrémité de sa course, à savoir celle correspondant à une condamnation de la serrure.When the locking of the lock is electrically controlled, for example, by an infrared control, the electric motor 7 is supplied. The electric motor 7 rotates the pinion 8, the rotational movement of which is transmitted to the screw 10 by the toothed wheel 9. The rotation of the screw 10 causes the nut 11 to move to the right, parallel to the axis B, as indicated by the arrow in FIG. 8. The nut 11 comes into contact, through the face 131 of the tooth 13, with the square return 420 of the lever 42. The nut 11 drives, during its translation, the lever 42 which pivots around the axis of the shaft 43. During the translation illustrated by the passage from FIG. 7 to FIG. 8, the driver 12 of the nut 11 runs along the lower edge of the lower grooves 18, 35, so that the nut 11 remains tilted upwards, as in FIG. 4. When the driver 12 is at the right end of the lower grooves 18, 35, as shown in FIG. 8, the lever 42 underwent the rotation necessary to tilt the plate 44 around the shaft 43, in the direction which brings it towards the second end of its travel, namely that corresponding to a locking of the lock.

Ensuite, l'entraîneur 12 de l'écrou 11 longe les rampes droites 19, 36 des deux profils de came 21 et 38, provoquant la rotation de l'écrou 11, comme le montre le passage de la figure 4 à la figure 5. La face 131 de la dent 13 de l'écrou 11 n'est alors plus en contact avec le levier 42: le levier 42 est libre. Lorsque l'entraîneur 12 de l'écrou 11 arrive en haut des rampes 19, 36 des deux profils de came 21, 38, il pénètre dans les rainures supérieures 17, 33. L'écrou 11 a subi une rotation supplémentaire et se trouve basculé vers le bas, comme le montre la figure 6. La dent 13 passe sous le retour en équerre 420 du levier 42.Then, the driver 12 of the nut 11 runs along the straight ramps 19, 36 of the two cam profiles 21 and 38, causing the rotation of the nut 11, as the shows the passage from Figure 4 to Figure 5. The face 131 of the tooth 13 of the nut 11 is then no longer in contact with the lever 42: the lever 42 is free. When the driver 12 of the nut 11 arrives at the top of the ramps 19, 36 of the two cam profiles 21, 38, it enters the upper grooves 17, 33. The nut 11 has undergone an additional rotation and is tilted downwards, as shown in FIG. 6. The tooth 13 passes under the square return 420 of the lever 42.

Puis, l'entraîneur 12 se déplace dans les rainures supérieures 17, 33, parallèlement à l'axe B de la vis 10. A l'extrémité droite de la rainure supérieure 33 du deuxième profil de came 38, l'entraîneur 12 de l'écrou 11 prend appui sur la portée d'appui 39 du coulisseau 22. Le coulisseau 22, entraîné par l'écrou 11, se déplace parallèlement à l'axe B, vers la droite, comme le montre la figure 10. Lorsque le coulisseau 22 se déplace en translation, la coopération du coulisseau 22 avec le micro-contact 41 n'est plus assurée, l'alimentation électrique du moteur est coupée et le frein 40 du coulisseau 22 fonctionne pour arrêter la translation. La figure 10 montre le dispositif arrêté, lorsque la serrure est en position de condamnation: le levier 42 est libre.Then, the driver 12 moves in the upper grooves 17, 33, parallel to the axis B of the screw 10. At the right end of the upper groove 33 of the second cam profile 38, the driver 12 of the nut 11 is supported on the bearing surface 39 of the slide 22. The slide 22, driven by the nut 11, moves parallel to the axis B, to the right, as shown in Figure 10. When the slide 22 moves in translation, the cooperation of the slide 22 with the microswitch 41 is no longer ensured, the electrical supply to the motor is cut off and the brake 40 of the slide 22 operates to stop the translation. FIG. 10 shows the device stopped, when the lock is in the locked position: the lever 42 is free.

Lorsque la super-condamnation est commandée électriquement, le coulisseau 22 et l'écrou 11 continuent leur translation, l'entraîneur 12 longeant la bordure inférieure des rainures supérieures 17, 33. La figure 11 montre le dispositif en fin de course: pendant la phase finale de translation, la patte 31 entre en contact avec le bras 47, le bras 47 pivote autour de l'axe de l'arbre 49, puis l'extrémité du bras 47 vient en contact avec la face inférieure de la patte 31, bloquant le bras 47 dans sa position. La serrure est en position de super-condamnation.When the superlatching is electrically controlled, the slider 22 and the nut 11 continue their translation, the driver 12 running along the lower edge of the upper grooves 17, 33. FIG. 11 shows the device at the end of the stroke: during the phase final translation, the lug 31 comes into contact with the arm 47, the arm 47 pivots about the axis of the shaft 49, then the end of the arm 47 comes into contact with the underside of the lug 31, blocking the arm 47 in its position. The lock is in the super-locking position.

Lorsqu'on supprime, par commande électrique, la super-condamnation puis la condamnation de la serrure, l'écrou 11 et le coulisseau 22 décrivent un mouvement de translation dans le sens inverse au mouvement décrit précédemment. Pour cela, le moteur électrique 7 commande, par l'intermédiaire du pignon 8 et de la roue dentée 9, un mouvement de rotation, de sens inverse au précédent, de la vis 10. Dans un premier temps, l'écrou 11 se déplace vers la gauche parallèlement à l'axe B comme l'indique la flèche de la figure 12; l'entraîneur 12 de l'écrou 11 se déplace le long de la bordure supérieure de la rainure supérieure 33 du coulisseau 22. Dans un deuxième temps, l'entraîneur 12 vient en appui sur la butée 34 du deuxième profil de came 38 du coulisseau 22 (figure 12): l'écrou 11 entraîne alors le coulisseau 22 dans un mouvement de translation vers la gauche, parallèlement à l'axe B. Pendant cette translation, dans un premier temps, la patte 31 libère le bras 47 qui pivote sous l'action de son ressort de rappel 56 et se retrouve dans sa position initiale de la figure 10: on a ainsi supprimé la super-condamnation de la serrure. Dans un deuxième temps, la dent 14 prend contact, par sa face 142, avec le levier 42, comme le montre la figure 13. L'entraîneur 12 continue de longer la bordure supérieure de la rainure supérieure 17 du premier profil de came 21, en prenant toujours appui sur la butée 34 du deuxième profil de came 38. L'écrou 11, dans sa translation, entraîne le levier 42 qui pivote autour de l'axe de l'arbre 43. Lorsque l'entraîneur 12 arrive à l'extrémité gauche de la rainure supérieure 17 du premier profil de came 21, le levier 42 est revenu au voisinage de la première extrémité de sa course, comme le montre la figure 13.When removing, by electrical control, the super-locking then the locking of the lock, the nut 11 and the slide 22 describe a translational movement in the opposite direction to the movement described above. For this, the electric motor 7 controls, by means of the pinion 8 and the toothed wheel 9, a rotational movement, in the opposite direction to the previous one, of the screw 10. First, the nut 11 moves to the left parallel to the axis B as indicated by the arrow in Figure 12; the driver 12 of the nut 11 moves along the upper edge of the upper groove 33 of the slider 22. In a second step, the driver 12 comes to bear on the stop 34 of the second cam profile 38 of the slider 22 (Figure 12): the nut 11 then drives the slide 22 in a translational movement to the left, parallel to the axis B. During this translation, at first, the tab 31 releases the arm 47 which pivots under the action of its return spring 56 and is found in its initial position in FIG. 10: the super-locking of the lock has thus been eliminated. In a second step, the tooth 14 makes contact, by its face 142, with the lever 42, as shown in FIG. 13. The driver 12 continues to follow the upper edge of the upper groove 17 of the first cam profile 21, while still bearing on the stop 34 of the second cam profile 38. The nut 11, in its translation, drives the lever 42 which pivots around the axis of the shaft 43. When the driver 12 arrives at the left end of the upper groove 17 of the first cam profile 21, the lever 42 has returned to the vicinity of the first end of its travel, as shown in FIG. 13.

Ensuite, l'entraîneur 12 de l'écrou 11 longe les rampes 20, 37 des premier et deuxième profils de came 21, 38, engendrant le basculement de l'écrou du bas (figure 6) vers le haut (figure 4) en passant par la position intermédaire illustrée par la figure 5. La dent 14 passe au-dessus du levier 42. Le levier 42 se trouve alors libre et la serrure est décondamnée.Then, the driver 12 of the nut 11 runs along the ramps 20, 37 of the first and second profiles of cam 21, 38, causing the nut to tilt from the bottom (Figure 6) upwards (Figure 4) passing through the intermediate position illustrated in Figure 5. The tooth 14 passes over the lever 42. The lever 42 is then free and the lock is unlocked.

Enfin, l'entraîneur 12 longe le bord supérieur des rainures inférieures 18, 35. L'écrou 11 et le coulisseau 22 achèvent leur mouvement de translation à l'extrémité gauche des rainures inférieures 18, 35, dans la position illustrée par la figure 7.Finally, the driver 12 runs along the upper edge of the lower grooves 18, 35. The nut 11 and the slide 22 complete their translational movement at the left end of the lower grooves 18, 35, in the position illustrated in FIG. 7 .

En se reportant à la figure 14, on voit que la serrure est en position de décondamnation. Le poussoir 48 est dans sa première position. Lorsque le levier 42 pivote, il provoque la rotation de la platine 44 autour de l'axe de l'arbre 43, engendrant le déplacement de la coulisse 50 par rapport au poussoir 48, comme le montre la figure 15; l'extrémité arrondie du poussoir 48 se trouve alors dans la largeur minimale de la rainure-glissière 52 de la coulisse 50. La serrure se trouve ainsi en position de condamnation.Referring to Figure 14, we see that the lock is in the unlocked position. The pusher 48 is in its first position. When the lever 42 pivots, it causes the rotation of the plate 44 around the axis of the shaft 43, causing the displacement of the slide 50 relative to the pusher 48, as shown in FIG. 15; the rounded end of the pusher 48 is then in the minimum width of the slide groove 52 of the slide 50. The lock is thus in the locked position.

La serrure peut être décondamnée en commandant électriquement comme ci-dessus expliqué, par exemple avec une commande infrarouge, le pivotement du levier 42. Si le dispositif de commande électrique est en panne, le levier 42 étant libre, la décondamnation peut s'opérer manuellement. De l'extérieur du véhicule, on agit sur la clé associée au barillet de sûreté de la serrure, ce qui provoque la rotation de la platine 44 ainsi que celle du levier 42. De l'intérieur du véhicule, on agit manuellement sur la tirette de frise; l'extrémité 55 de cette tirette de frise se trouve dans celle des zones de la fenêtre 51 qui constitue un rectangle de petite longueur car le poussoir 48 maintient, sous l'action de son ressort de rappel 56, la coulisse 50 dans sa position la plus proche de l'axe de l'arbre 43. En conséquence, l'extrémité 55 agit sur la bordure inférieure de la fenêtre 51, ce qui entraîne une rotation de la platine 44, illustrée par le passage de la figure 15 à la figure 14.The lock can be unlocked by electrically controlling, as explained above, for example with an infrared control, the pivoting of the lever 42. If the electrical control device is faulty, the lever 42 being free, unlocking can be carried out manually . From the outside of the vehicle, the key associated with the safety barrel of the lock is acted upon, which causes the rotation of the plate 44 as well as that of the lever 42. From the interior of the vehicle, one acts manually on the zipper frieze; the end 55 of this frieze zipper is in that of the zones of the window 51 which constitutes a rectangle of small length because the pusher 48 maintains, under the action of its return spring 56, the slide 50 in its position closest to the axis of the shaft 43. Consequently, the end 55 acts on the lower edge of the window 51, which causes a rotation of the plate 44, illustrated by the passage from FIG. 15 to Figure 14.

La serrure étant condamnée (figure 15), elle peut être amenée en position de super-condamnation (figure 16) par commande électrique. Le bras 47, entraîné par le dispositif de commande électrique pivote et le poussoir 48, à l'encontre de son ressort de rappel 56, se déplace et se trouve alors dans sa deuxième position (figure 16). Le déplacement du poussoir 48 provoque la translation de la coulisse 50 parallèlement aux prolongements 46 de la platine 44. Dans ce cas, l'extrémité 55 de la tirette de frise se trouve dans la zone de plus grande longueur de la fenêtre 51. En agissant manuellement sur la tirette de frise, on ne provoque pas la rotation de la platine 44 car l'extrémité 55 n'a qu'un mouvement dont l'amplitude ne lui permet pas de venir en contact avec la bordure inférieure (sur la figure 16) de la fenêtre 51; on ne peut donc pas décondamner la serrure, ce qui assure la fonction de super-condamnation.The lock being locked (Figure 15), it can be brought into the super-locked position (Figure 16) by electrical control. The arm 47, driven by the electrical control device pivots and the pusher 48, against its return spring 56, moves and is then in its second position (Figure 16). The movement of the pusher 48 causes the translation of the slide 50 parallel to the extensions 46 of the plate 44. In this case, the end 55 of the frieze zipper is in the region of greatest length of the window 51. By acting manually on the frieze zipper, the plate 44 is not caused to rotate because the end 55 has only one movement whose amplitude does not allow it to come into contact with the lower edge (in FIG. 16 ) from window 51; therefore, the lock cannot be unlocked, which provides the super-locking function.

La serrure étant en position de super-condamnation (figure 16), elle peut être ramenée, par commande électrique, en position de condamnation puis de décondamnation. Pour ramener la serrure à sa position de condamnation, le dispositif de commande électrique libère le bras 47 en déplaçant la cale, que constitue la patte 31, et le poussoir 48, grâce à l'action du ressort de rappel 56, revient à sa première position (figure 15), provoquant dans son déplacement, la translation de la coulisse 50 parallèlement aux prolongements 46 de la platine 44. L'extrémité de la tirette de frise 55 se loge dans la zone de plus petite longueur de la fenêtre 51 (figure 15). Pour ramener la serrure à sa position de décondamnation, le dispositif de commande électrique fait pivoter le levier 42 de sa deuxième extrémité de course à sa première extrémité de course, engendrant la rotation de la platine 44 autour de l'axe de l'arbre 43 pour ramener tous les éléments dans la position qu'ils occupent sur la figure 14.The lock being in the super-locking position (FIG. 16), it can be brought back, by electrical control, to the locking and then unlocking position. To return the lock to its locked position, the electrical control device releases the arm 47 by moving the wedge, which constitutes the tab 31, and the pusher 48, thanks to the action of the return spring 56, returns to its first position (Figure 15), causing in its displacement, the translation of the slide 50 parallel to the extensions 46 of the plate 44. The end of the frieze zipper 55 is housed in the region of shorter length of the window 51 (Figure 15). To return the lock to its unlocking position, the electrical control device pivots the lever 42 from its second stroke end to its first stroke end, causing the rotation of the plate 44 about the axis of the shaft 43 to bring all the elements back to the position they occupy in figure 14.

Si le dispositif de commande électrique est en panne, le levier 42 étant libre, la serrure super-condamnée peut être décondamnée, par voie manuelle, en agissant sur la clé associée au barillet de sûreté de la serrure, ce qui ramène la serrure en position de décondamnation par commande mécanique de la rotation de la platine 44 autour de l'axe de l'arbre 43. Le bras 47 et le poussoir 48 sont maintenus dans leur position par appui sur la patte 31 du dispositif de commande électrique. La coulisse 50 reste à l'extrémité des prolongements 46 de la platine 44 et l'extrémité 55 de la tirette de frise reste dans la zone de plus grande longueur de la fenêtre 51. Le dispositif de super-condamnation de la serrure (figure 17) sera ramené à sa position de décondamnation (figure 14) lors de la réparation du dispositif de commande électrique.If the electric control device is faulty, the lever 42 being free, the super-locked lock can be unlocked, by manual way, by acting on the key associated with the safety barrel of the lock, which brings the lock back into position. unlocking by mechanical control of the rotation of the plate 44 around the axis of the shaft 43. The arm 47 and the pusher 48 are held in their position by pressing on the tab 31 of the electrical control device. The slide 50 remains at the end of the extensions 46 of the plate 44 and the end 55 of the frieze zipper remains in the zone of greatest length of the window 51.
