It will be noted that the second face 18B of the plate comprises a first housing 26, generally oblong, in which are arranged the means of reduction 24, and a second housing 28 in which the organ is arranged training 22.

Le premier logement 26 est délimité par une jupe 30 comportant une partie longitudinale 30L de séparation des premier 26 et second 28 logements.The first housing 26 is delimited by a skirt 30 comprising a part longitudinal 30L of separation of the first 26 and second 28 housings.

Le second logement 28 est délimité par un bord périphérique 18P de la platine interrompu par un orifice 32 faisant communiquer ce second logement 28 avec l'extérieur du corps 16. Cet orifice 32 forme un passage pour un bouton de commande 34 solidaire de l'organe d'entraínement 22.The second housing 28 is delimited by a peripheral edge 18P of the plate interrupted by an orifice 32 making this second housing 28 communicate with the outside of the body 16. This orifice 32 forms a passage for an integral control button 34 of the drive member 22.

Les moyens de démultiplication 24 comprennent une crémaillère mobile 36, liée à l'organe d'entraínement 22, une crémaillère fixe 38, solidaire de la seconde face 18B de la platine, et un pignon mobile étagé 40 muni d'une denture D1 de petit diamètre engrenant avec la crémaillère mobile 36 et d'une denture D2 de grand diamètre engrenant avec la crémaillère fixe 38.The reduction means 24 comprise a movable rack 36, linked to the drive member 22, a fixed rack 38, integral with the second face 18B of the plate, and a stepped movable pinion 40 provided with a teeth D1 of small diameter meshing with the movable rack 36 and a D2 toothing of large diameter meshing with the fixed rack 38.

L'organe d'entraínement 22 est relié à la crémaillère mobile 36 par une liaison pivot d'axe sensiblement perpendiculaire à la direction de translation de cet organe d'entraínement 22.The drive member 22 is connected to the movable rack 36 by a link pivot axis substantially perpendicular to the direction of translation of this member training 22.

La liaison pivot est matérialisé par un pion transversal 42, solidaire de l'organe d'entraínement 22, logé à rotation dans un oeillet 44, formant palier, solidaire de la crémaillère mobile 36. L'oeillet 44 s'étend à travers un passage 46 ménagé dans la paroi de séparation 30L de façon à faire communiquer entre eux les premier 26 et second 28 logements.The pivot link is materialized by a transverse pin 42, integral with the member 22, rotatably housed in an eyelet 44, forming a bearing, integral with the movable rack 36. The eyelet 44 extends through a passage 46 formed in the wall separation 30L so that the first 26 and second 28 communicate with each other housing.

On notera que la paroi de séparation 30L participe au guidage en translation de l'organe d'entraínement 22 et de la crémaillère mobile 26. On notera également que le bord périphérique 18P de la platine participe au guidage en translation de l'organe d'entraínement 22.Note that the partition wall 30L participates in guiding in translation of the drive member 22 and the movable rack 26. It will also be noted that the peripheral edge 18P of the plate participates in guiding in translation of the member training 22.

Le pignon étagé 40 est monté libre en rotation sur un arbre 48, représenté en détail sur la figure 2, d'axe orthogonal à la direction de translation du panneton 16. Cet arbre 48 comprend une première extrémité 48A de liaison avec le panneton 16, encastrée dans un orifice correspondant 50 ménagé dans ce panneton 16. L'arbre 48 comprend également une seconde extrémité de guidage 48B coopérant avec une rainure de guidage complémentaire 52 ménagé dans la face interne de la seconde coque 20B (voir figure 5). On notera donc que le panneton 16 est lié à l'arbre 48 autour duquel le pignon étagé 40 est monté librement rotatif.The stepped pinion 40 is mounted to rotate freely on a shaft 48, shown in detail in FIG. 2, of axis orthogonal to the direction of translation of the bit 16. This shaft 48 includes a first end 48A for connection with the bit 16, embedded in a corresponding orifice 50 formed in this bit 16. The shaft 48 comprises also a second guide end 48B cooperating with a groove of complementary guide 52 formed in the internal face of the second shell 20B (see figure 5). It will therefore be noted that the bit 16 is linked to the shaft 48 around which the pinion stepped 40 is mounted freely rotatable.

Les déplacements de l'organe d'entraínement 22 et de la crémaillère mobile 36 sont limités de façon connue en soi à l'aide de butées de fin de course ménagées sur la seconde face 18B de la platine. Les déplacements du pignon étagés 14 relativement notamment à la crémaillère fixe 38 sont limités par les extrémités du premier logement 26 délimitées par la jupe 30. The displacements of the drive member 22 and the movable rack 36 are limited in a manner known per se with the aid of limit stops provided on the second face 18B of the plate. Displacements of the stepped pinion 14 relatively in particular to the fixed rack 38 are limited by the ends of the first housing 26 delimited by the skirt 30.

En se référant aux figures 6 à 8, on voit que l'organe d'entraínement 22 est déplaçable entre sa première position, telle que représentée sur la figure 6, et sa seconde position, telle que représentée sur la figure 8, par franchissement d'un point dur matérialisé par un ressort bistable 54 reliant l'organe d'entraínement 22 et la platine 18. Ce ressort 54, par exemple en forme d'épingle, comprend une première branche 54A, emboítée dans une encoche 56 ménagée dans la platine 18, et une seconde branche 54B, logée dans un orifice transversal 58 ménagé dans l'organe d'entraínement 22.Referring to Figures 6 to 8, we see that the drive member 22 is movable between its first position, as shown in Figure 6, and its second position, as shown in Figure 8, by crossing a hard point materialized by a bistable spring 54 connecting the drive member 22 and the plate 18. This spring 54, for example in the form of a pin, comprises a first branch 54A, nested in a notch 56 formed in the plate 18, and a second branch 54B, housed in a transverse orifice 58 formed in the drive member 22.

La liaison pivot matérialisée par le pion 42 et l'oeillet 44 autorise, lorsque l'organe d'entraínement 22 est dans sa première position (panneton 16 en position d'utilisation), le basculement de cet organe d'entraínement 22 entre les deux positions représentées respectivement sur les figures 6 et 7.The pivot link materialized by the pin 42 and the eyelet 44 allows, when the drive member 22 is in its first position (bit 16 in position of use), the tilting of this drive member 22 between the two positions shown in Figures 6 and 7 respectively.

La position représentée sur la figure 6 correspond à une position d'arcboutement de l'organe d'entraínement 22 interdisant le déplacement en translation de cet organe d'entraínement 22 le long des moyens de guidage en translation formés par la paroi de séparation 30L et la paroi périphérique 18P de la platine. En effet, l'organe d'entraínement 22 est en appui contre une butée d'arc-boutement 60 ménagée dans la platine 18, plus particulièrement dans la paroi de séparation 30L.The position shown in Figure 6 corresponds to a bend position of the drive member 22 prohibiting movement in translation of this drive member 22 along the translational guide means formed by the partition wall 30L and the peripheral wall 18P of the plate. Indeed, the organ 22 is in abutment against a bracing stop 60 formed in the plate 18, more particularly in the partition wall 30L.

La position représentée sur la figure 7 correspond à une position d'alignement de l'organe d'entraínement 22 avec les moyens de guidage en translation formés par la paroi de séparation 30L et la paroi périphérique 18P de la platine.The position shown in Figure 7 corresponds to an alignment position of the drive member 22 with the translational guide means formed by the partition wall 30L and the peripheral wall 18P of the plate.

En se référant à la figure 6, on notera que, lorsque l'organe d'entraínement 22 est dans sa première position (panneton 16 en position d'utilisation), le ressort bistable 54 rappelle cet organe d'entraínement 22 vers sa position d'arc-boutement.Referring to Figure 6, it will be noted that when the drive member 22 is in its first position (bit 16 in use position), the bistable spring 54 recalls this drive member 22 to its bracing position.

On décrira ci-dessous les principaux aspects du fonctionnement de la clé 12 liés à l'invention.The main aspects of the operation of the key 12 will be described below. related to the invention.

Initialement, le panneton 16 de la clé est dans sa position d'utilisation telle que représentée sur les figures 1, 3 et 6. Par rapport à son mouvement de translation, l'organe d'entraínement 22 est dans sa première position correspondant à la position d'utilisation du panneton 16. Par rapport à son mouvement de basculement autour de l'axe géométrique matérialisé par le pion 42 et l'oeillet 44, l'organe d'entraínement 22 est dans sa position d'arc-boutement interdisant le déplacement en translation intempestif de cet organe d'entraínement 22 et donc du panneton 16.Initially, the bit 16 of the key is in its position of use such that represented in FIGS. 1, 3 and 6. With respect to its translational movement, the member 22 is in its first position corresponding to the position of use bit 16. Relative to its tilting movement around the axis geometric materialized by the pin 42 and the eyelet 44, the drive member 22 is in its bracing position preventing inadvertent translation movement of this drive member 22 and therefore bit 16.

Pour escamoter le panneton 16 dans le corps 14 de la clé, l'utilisateur appuie tout d'abord sur l'organe d'entraínement 22, à l'encontre de la force de rappel du ressort 54, de façon à faire basculer cet organe 22 vers sa position d'alignement avec les moyens de guidage en translation 30L, 18P, telle que représentée sur la figure 7. To retract the bit 16 in the body 14 of the key, the user presses first of all on the drive member 22, against the return force of the spring 54, so as to tilt this member 22 towards its position of alignment with the means in guiding in translation 30L, 18P, as shown in FIG. 7.

Puis, l'utilisateur pousse lorgane d'entraínement 22 en translation vers sa seconde position correspondant à la position escamotée du panneton 16, telle que représentée sur les figures 4 et 8.Then, the user pushes the drive member 22 in translation towards its second position corresponding to the retracted position of the bit 16, such that shown in Figures 4 and 8.

Au cours de ce déplacement en translation, l'organe 22 entraíne la crémaillère mobile 36 dans le même sens. Le déplacement de la crémaillère mobile 36 entraíne le pignon étagé 40 qui roule sur les crémaillères 36, 38. L'organe 22, la crémaillère mobile 36 et le pignon 40 se déplacent en translation dans le même sens. En effet, le déplacement du pignon 40 dans un sens opposé à celui de la crémaillère mobile 36 est interdit par la jupe 30 formant butée de fin de course en translation du pignon 40 (voir figure 3).During this translational movement, the member 22 drives the rack mobile 36 in the same direction. The movement of the movable rack 36 causes the stepped pinion 40 which rolls on the racks 36, 38. The member 22, the movable rack 36 and the pinion 40 move in translation in the same direction. Indeed, the displacement of the pinion 40 in a direction opposite to that of the movable rack 36 is prohibited by the skirt 30 forming end of travel stop in translation of the pinion 40 (see figure 3).

Compte tenu des diamètres différents des dentures D1, D2 engrenant respectivement avec les crémaillères mobile 36 et fixe 38, le déplacement du panneton 16 est démultiplié par rapport à celui de l'organe d'entraínement 22 d'un rapport dépendant du rapport des diamètres des dentures D1, D2.Taking into account the different diameters of the teeth D1, D2 meshing respectively with the movable and fixed racks 36, the displacement of the bit 16 is multiplied compared to that of the drive member 22 of a dependent report the ratio of the diameters of the teeth D1, D2.

Si l'utilisateur souhaite replacer le panneton 16 en position d'utilisation, il déplace l'organe d'entraínement 22 en translation, dans un sens opposé à celui décrit précédemment, vers sa première position telle que représentée sur la figure 6, dans laquelle cet organe d'entraínement 22 se place automatiquement en position d'arc-boutement sous l'effet de rappel élastique du ressort 54.If the user wishes to replace the bit 16 in the position of use, it moves the drive member 22 in translation, in a direction opposite to that described previously, towards its first position as shown in FIG. 6, in which this drive member 22 is automatically placed in the bracing position under the elastic return effect of the spring 54.

Les figures 9 et 10 concernent une clé selon, respectivement, des deuxième et troisième modes de réalisation de l'invention. Sur ces figures, les éléments analogues à ceux des figures 1 à 8 sont désignés par des références identiques.Figures 9 and 10 relate to a key according to, respectively, second and third embodiments of the invention. In these figures, elements similar to those of FIGS. 1 to 8 are designated by identical references.

Sur la figure 9, on a représenté schématiquement des moyens 24 de démultiplication de mouvement pour la clé selon le deuxième mode de réalisation de l'invention.In Figure 9, there is schematically shown means 24 of reduction of movement for the key according to the second embodiment of the invention.

Dans ce cas, les moyens de démultiplication 24 sont de type fluidique, plus particulièrement de type hydraulique.In this case, the reduction means 24 are of the fluid type, more particularly of hydraulic type.

Les moyens de démultiplication de mouvement 24 comprennent une chambre hydraulique étagée 60, dite chambre de démultiplication, comportant une extrémité 60A de grande section, dans laquelle coulisse un piston 62 de grand diamètre, et une extrémité de petite section 60B, dans laquelle coulisse un piston 64 de petit diamètre.The movement reduction means 24 include a chamber hydraulic stepped 60, called reduction chamber, having one end 60A of large section, in which slides a piston 62 of large diameter, and a end of small section 60B, in which slides a piston 64 of small diameter.

Le piston de grand diamètre 62 est relié à l'organe d'entraínement 22. Le piston de petit diamètre 64 est relié au panneton 16, par exemple au moyen d'un lien souple tel qu'un câble 66.The large diameter piston 62 is connected to the drive member 22. The small diameter piston 64 is connected to bit 16, for example by means of a link flexible such as a cable 66.

En variante, le piston de petit diamètre 64 pourrait être formé par une extrémité du panneton 16. Alternatively, the small diameter piston 64 could be formed by a end of bit 16.

De préférence, la chambre de démultiplication est ménagée dans le corps 14 de la clé par moulage.Preferably, the reduction chamber is formed in the body 14 of the key by molding.

Dans ce deuxième mode de réalisation de l'invention, le rapport de démultiplication de mouvement dépend du rapport des surfaces des pistons de grand 62 et petit 64 diamètres.In this second embodiment of the invention, the ratio of reduction in movement depends on the ratio of the surfaces of the pistons of large 62 and small 64 diameters.

Sur la figure 10, on a représenté schématiquement des moyens électriques pour une clé selon le troisième mode de réalisation de l'invention. Ces moyens électriques comprennent notamment un moteur électrique formant l'organe d'entraínement 22. L'arbre de ce moteur électrique 22 est couplé, de façon connue en soi, à la crémaillère mobile 44.In Figure 10, there is shown schematically electrical means for a key according to the third embodiment of the invention. These electrical means include in particular an electric motor forming the drive member 22. The shaft of this electric motor 22 is coupled, in a manner known per se, to the rack mobile 44.

Le moteur électrique 22 est piloté, par exemple, par un des boutons de commande B1 à B3. Ainsi, le bouton B1 par exemple peut être commun à la commande du moteur électrique 22 et à la télécommande d'au moins un organe du véhicule tel qu'un organe de verrouillage d'un ouvrant de ce véhicule.The electric motor 22 is controlled, for example, by one of the buttons command B1 to B3. Thus, the button B1 for example can be common to the command the electric motor 22 and the remote control of at least one member of the vehicle such as locking member of an opening of this vehicle.

Le moteur électrique 22 et le bouton de commande B1 sont reliés à des moyens électroniques classiques 68, portés par le corps 14, permettant de faire la discrimination entre une commande du moteur électrique 22 et une télécommande de l'organe de véhicule automobile par reconnaissance de durées de pressions ou de séquences de pressions exercées sur le bouton de commande B1.The electric motor 22 and the control button B1 are connected to conventional electronic means 68, carried by the body 14, making it possible to make the discrimination between a control of the electric motor 22 and a remote control of the motor vehicle body by recognition of durations of pressure or pressure sequences exerted on the control button B1.

En variante, le moteur électrique 22 peut être commandé par un bouton de commande spécifique à ce moteur 22.Alternatively, the electric motor 22 can be controlled by a button control specific to this engine 22.

Le cas échéant, le corps 14 de clé est muni de capteurs 70, 72 de fin de course du panneton 16, notamment du type à effet Hall.Where appropriate, the key body 14 is provided with sensors 70, 72 at the end of travel of the bit 16, in particular of the Hall effect type.

Parmi les avantages de l'invention, on notera que celle-ci permet, à l'aide de moyens simples et fiables, d'entraíner le panneton 16 entre ses positions d'utilisation et escamotée en évitant notamment à l'utilisateur d'avoir à agir sur ce panneton.Among the advantages of the invention, it will be noted that it allows, using simple and reliable means of driving the bit 16 between its positions of use and retracted, in particular avoiding the user having to act on this bit.
