Description

Description Clé à tige escamotable comportant des moyens d'entraînement de la tige vers une position déployée Description Retractable rod wrench comprising means for driving the rod to a deployed position
[001] L'invention propose une clé comportant une tige escamotable à l'intérieur de la tête de clé.The invention provides a key comprising a retractable rod inside the key head.
[002] L'invention propose plus particulièrement une clé, notamment de véhicule automobile, du type comportant une tige escamotable qui est montée pivotante par rapport à un boîtier formant tête de manœuvre de la clé, entre une position escamotée dans laquelle la tige s'étend selon une direction sensiblement longitudinale à l'intérieur d'un logement du boîtier, et une position déployée d'utilisation dans laquelle au moins un tronçon de la tige de clé s'étend à l'extérieur du boîtier, dans laquelle la tige comporte une première extrémité formant talon, par l'intermédiaire de laquelle elle est articulée par rapport au boîtier autour d'un axe vertical d'articulation orthogonal à l'axe de la tige.The invention more particularly provides a key, in particular for a motor vehicle, of the type comprising a retractable rod which is pivotally mounted relative to a housing forming the key operating head, between a retracted position in which the rod s' extends in a substantially longitudinal direction inside a housing of the housing, and a deployed position of use in which at least one section of the key rod extends outside the housing, in which the rod comprises a first end forming a heel, by means of which it is articulated relative to the housing about a vertical axis of articulation orthogonal to the axis of the rod.
[003] La clé proposée comporte, d'une part, des moyens pour le verrouillage angulaire de la tige en position escamotée, et d'autre part, des moyens pour le verrouillage angulaire de la tige en position déployée.The proposed key comprises, on the one hand, means for the angular locking of the rod in the retracted position, and on the other hand, means for the angular locking of the rod in the deployed position.
[004] L'ensemble formé par la tige de clé, aussi appelée "insert", et la tête de clé est relativement encombrant, lorsque la tige s'étend longitudinalement à l'extérieur de la tête de clé.The assembly formed by the key rod, also called an "insert", and the key head is relatively bulky, when the rod extends longitudinally outside the key head.
[005] De plus, lorsque la clé est placée dans la poche d'un vêtement, la tige de clé risque de provoquer une usure prématurée de cette poche, voir de former un trou, ce qui est for dommageable.In addition, when the key is placed in the pocket of a garment, the key rod may cause premature wear of this pocket, see forming a hole, which is highly damaging.
[006] Pour limiter cet inconvénient, il a été proposé de moyens permettant d'escamoter la tige à l'intérieur du boîtier formant la tête de la clé.To limit this drawback, means have been proposed for retracting the rod inside the housing forming the head of the key.
[007] Le document DE-A-39.02.537 décrit une clé comportant une tige escamotable, dans laquelle le mouvement de la tige de sa position escamotée vers sa position déployée d'utilisation est automatique.Document DE-A-39.02.537 describes a key comprising a retractable rod, in which the movement of the rod from its retracted position to its deployed position of use is automatic.
[008] La tige est montée articulée dans le boîtier par l'intermédiaire d'un élément d'articulation dans lequel sont agencés des moyens de verrouillage en position de la tige, ainsi que les moyens d'entraînement de la tige vers sa position déployée.The rod is mounted articulated in the housing by means of an articulation element in which are arranged locking means in position of the rod, as well as the means for driving the rod towards its deployed position. .
[009] Un tel montage de la tige nécessite donc d'utiliser un grand nombre de composants qui sont en outre relativement encombrants.Such an assembly of the rod therefore requires the use of a large number of components which are also relatively bulky.
[010] Ces composants monopolisent un volume important à l'intérieur du boîtier de la tête, et ils réduisent fortement le volume du boîtier disponible pour y agencer un dispositif électronique permettant par exemple de commander à distance le ver- rouillage des portières du véhicule.These components monopolize a large volume inside the housing of the head, and they greatly reduce the volume of the housing available to arrange an electronic device therefor for example to remotely control the rusting of vehicle doors.
[01 1] L'invention a pour but de proposer une clé comportant une tige escamotable, pour laquelle le nombre de composants nécessaires à l'articulation de la tige par rapport au boîtier, et à l'entraînement de la tige vers une position déployée, est réduit.[01 1] The invention aims to provide a key comprising a retractable rod, for which the number of components necessary for the articulation of the rod relative to the housing, and for driving the rod towards a deployed position , is reduced.
[012] Dans ce but, l'invention propose une clé du type décrit précédemment, caractérisée en ce que les moyens de verrouillage comportent un élément de verrouillage unique monté mobile à l'intérieur du boîtier, qui coopère directement avec le talon de la tige pour verrouiller la tige en position escamotée ou en position déployée.For this purpose, the invention provides a key of the type described above, characterized in that the locking means comprise a single locking element mounted movably inside the housing, which cooperates directly with the heel of the rod to lock the rod in the retracted position or in the deployed position.

[015] Pour la description de l'invention, on adoptera à titre non limitatif les orientations verticale, longitudinale et transversale selon le repère V, L, T indiqué aux figures.For the description of the invention, the vertical, longitudinal and transverse orientations will be adopted, without limitation, according to the reference V, L, T indicated in the figures.
[016] On adoptera aussi l'orientation d'avant en arrière comme étant la direction longitudinale et de gauche à droite en se reportant à la figure 1.We will also adopt the orientation from front to back as being the longitudinal direction and from left to right, referring to FIG. 1.
[017] Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence.In the description which follows, identical, similar or analogous elements will be designated by the same reference numbers.
[018] On a représenté à la figure 1 une clé 10 qui permet de faire fonctionner le mécanisme d'une serrure munie d'un verrou (non représentée) d'un véhicule automobile qui comporte un boîtier 12 et une tige de clé 14, aussi appelée "insert".FIG. 1 shows a key 10 which makes it possible to operate the mechanism of a lock provided with a lock (not shown) of a motor vehicle which comprises a housing 12 and a key rod 14, also called "insert".
[019] La clé 10 comporte aussi un dispositif électronique (non représenté) qui est fixé à l'intérieur du boîtier 12.The key 10 also includes an electronic device (not shown) which is fixed inside the housing 12.
[020] Le boîtier 12 forme la tête de la clé 10 et permet de manœuvrer la clé 10, notamment pour la faire pivoter dans le verrou de la serrure, autour de l'axe longitudinal de la tige 14.The housing 12 forms the head of the key 10 and makes it possible to operate the key 10, in particular to rotate it in the lock of the lock, around the longitudinal axis of the rod 14.
[021] La tige 14 est montée pivotante par rapport au boîtier 12 entre une position escamotée représentée à la figure 2, dans laquelle la tige s'étend à l'intérieur d'un logement 16 du boîtier 12, selon une orientation globalement longitudinale, et une position déployée d'utilisation, représentée à la figure 5, dans laquelle la tige 14 s'étend en partie à l'extérieur du boîtier 12.[021] The rod 14 is pivotally mounted relative to the housing 12 between a retracted position shown in Figure 2, in which the rod extends inside a housing 16 of the housing 12, in a generally longitudinal orientation, and a deployed position of use, shown in FIG. 5, in which the rod 14 partly extends outside the housing 12.
[022] Ici, lorsque la tige 14 est en position déployée, elle s'étend selon une orientation globalement transversale, c'est-à-dire qu'elle a pivoté d'un angle de 90 degrés par rapport à sa position escamotée. Cependant, il sera compris que l'invention n'est pas limitée à ce mode de réalisation et que la tige peut pivoter d'un angle plus ou moins important par rapport à sa position escamotée, notamment d'un angle de 180 degrés, dans quel cas la tige 14 s'étend selon une orientation globalement longitudinale à l'extérieur du boîtier 12.[022] Here, when the rod 14 is in the deployed position, it extends in a generally transverse orientation, that is to say that it has pivoted by an angle of 90 degrees relative to its retracted position. However, it will be understood that the invention is not limited to this embodiment and that the rod can pivot by a greater or lesser angle relative to its retracted position, in particular by an angle of 180 degrees, in in which case the rod 14 extends in a generally longitudinal orientation outside the housing 12.
[023] L'articulation de la tige 14 par rapport au boîtier 12 est réalisée par l'intermédiaire d'une première extrémité 18 de la tige 14 formant talon, qui est ici l'extrémité longitudinale avant de la tige 14, qui est traversée par un axe vertical 20.[023] The articulation of the rod 14 relative to the housing 12 is produced by means of a first end 18 of the rod 14 forming a heel, which is here the front longitudinal end of the rod 14, which is crossed by a vertical axis 20.
[024] Le logement 16, dans lequel la tige 14 est reçue lorsqu'elle est en position escamotée, est situé au niveau d'un bord latéral du boîtier 12, ici le bord latéral gauche, et il est ouvert et débouche vers l'extérieur le long du bord latéral gauche, pour permettre le passage de la tige 14 depuis ou vers sa position déployée.The housing 16, in which the rod 14 is received when it is in the retracted position, is located at a side edge of the housing 12, here the left side edge, and it is open and opens out towards the outside along the left side edge, to allow the passage of the rod 14 from or to its deployed position.
[025] Enfin, la clé 10 comporte des moyens pour le verrouillage de la tige 14 lorsqu'elle est en position escamotée et des moyens pour le verrouillage de la tige 14 lorsqu'elle est en position déployée.Finally, the key 10 includes means for locking the rod 14 when it is in the retracted position and means for locking the rod 14 when it is in the deployed position.
[026] Conformément à l'invention, ces moyens de verrouillage comportent un élément- de verrouillage unique 22 qui est monté mobile à l'intérieur du boîtier 12, et qui est apte à coopérer directement avec le talon 18 de la tige 14 pour réaliser le verrouillage de la tige 14 en position escamotée ou en position déployée.[026] According to the invention, these locking means comprise a single locking element 22 which is movably mounted inside the housing 12, and which is able to cooperate directly with the heel 18 of the rod 14 to achieve locking the rod 14 in the retracted position or in the deployed position.
[027] L'élément de verrouillage 22 comporte à cet effet un doigt de verrouillage 24 qui est apte à être reçu sélectivement dans une première encoche radiale 26 du talon 16, pour verrouiller la tige 14 en position escamotée, comme on l'a représenté à la figure 2, ou dans une deuxième encoche 28 du talon 16, pour verrouiller la tige 14 en position déployée, comme on l'a représenté à la figure 5.[027] The locking element 22 for this purpose comprises a locking finger 24 which is adapted to be received selectively in a first radial notch 26 of the heel 16, for locking the rod 14 in the retracted position, as shown in FIG. 2, or in a second notch 28 in the heel 16, for locking the rod 14 in the deployed position, as shown in FIG. 5.
[028] Pour permettre à la tige 14 de pivoter par rapport au boîtier 12, l'élément de verrouillage 22 est monté mobile par rapport au boîtier 12 entre sa position de verrouillage, dans laquelle le doigt de verrouillage 24 est reçu sélectivement dans la première encoche 26 ou dans la deuxième encoche 28, et une position de déverrouillage dans laquelle le doigt de verrouillage 24 s'étend hors de chaque encoche radiale 26, 28.[028] To allow the rod 14 to pivot relative to the housing 12, the locking element 22 is mounted movable relative to the housing 12 between its locking position, in which the locking finger 24 is selectively received in the first notch 26 or in the second notch 28, and an unlocking position in which the locking finger 24 extends out of each radial notch 26, 28.
[029] Le mouvement de l'élément de verrouillage 22 depuis sa position de verrouillage vers sa position de déverrouillage est actionné manuellement par l'utilisateur de la clé 10, par l'intermédiaire d'un élément de manœuvre 30 qui est une partie de l'élément de verrouillage 22, et qui s'étend en partie à l'extérieur du boîtier 12. [030] Ici, l'élément de manœuvre 30 traverse une ouverture 32 du boîtier 12, qui est réalisée au niveau du bord d'extrémité longitudinale avant du boîtier 12. [031] Le mouvement de l'élément de verrouillage 22 depuis sa position de déverrouillage vers sa position de verrouillage est par contre actionné par l'intermédiaire d'un élément élastique de rappel, ou ressort de rappel 34. [032] Ainsi, lorsque l'utilisateur commande le déverrouillage de la tige 14, il agit sur l'élément de manœuvre 30, à encontre de l'effort élastique de rappel exercé par le ressort de rappel 34 sur l'élément de verrouillage 22. [033] Lorsque la tige 14 est en position escamotée dans le logement 16 du boîtier 12, il est difficile de la saisir manuellement pour la faire ensuite pivoter vers sa position déployée. [034] C'est pourquoi la clé 10 comporte des moyens d'entraînement de la tige 14 depuis sa position escamotée vers une position intermédiaire, dans laquelle une partie de la tige 14 s'étend à l'extérieur du logement 16. [035] On a représenté aux figures 1 à 2D un premier mode de réalisation de l'invention selon laquelle les moyens d'entraînement de la tige 14 comportent un doigt d'entraînement 36 solidaire de l'élément de verrouillage 22, et qui est apte à coopérer avec le talon 18 de la tige 14. [036] Ici, le doigt d'entraînement 36 s'appuie contre une face verticale d'appui 38 du talon 18, qui s'étend radialement par rapport à l'axe 20 d'articulation, pour entraîner la tige 14. [037] Lorsque l'élément de verrouillage 22 est en position de verrouillage, comme on peut le voir à la figure 2, le doigt d'entraînement 36 s'étend à distance de la face d'appui 38. Ce jeu "j" qui est présent entre le doigt d'entraînement 36 et la face d'appui permet au doigt de verrouillage 24 de sortir de la première encoche 26, avant que l'élément de verrouillage 22 n'entraîne la tige 14. [038] Selon un mode de réalisation préféré de l'invention, la face verticale d'appui 38 est une portion de la deuxième encoche 28. [039] L'élément de verrouillage 22 est monté mobile par rapport au boîtier 12 en translation selon une direction horizontale transversale, et il comporte une partie 40 de forme globalement cylindrique, d'axe principal transversal, qui est guidée en translation dans un logement transversal complémentaire 42 du boîtier 12. [040] Pour sortir la tige 14 depuis sa position escamotée vers sa position déployée, dans un premier mouvement représenté à la figure 2A, l'utilisateur de la clé 10 agit sur l'élément de manœuvre 30 pour provoquer un déplacement de l'élément de verrouillage 22 depuis sa position de verrouillage, jusqu'à une position intermédiaire représentée à la figure 2B. [041] Dans cette position intermédiaire, le doigt de verrouillage 24 est sorti de la première encoche 26, et le doigt d'entraînement 36 est en appui contre la face d'appui 38 du talon 18.The movement of the locking element 22 from its locking position to its unlocking position is manually actuated by the user of the key 10, by means of an operating element 30 which is a part of the element of locking 22, and which extends partly outside the housing 12. [030] Here, the operating element 30 passes through an opening 32 of the housing 12, which is formed at the front longitudinal end edge of the housing 12. [031] The movement of the locking element 22 from its unlocking position to its locking position is however actuated by means of an elastic return element, or return spring 34. [032] Thus, when the user controls the unlocking of the rod 14, he acts on the operating element 30, against the elastic return force exerted by the return spring 34 on the locking element 22. [033 ] When the rod 14 is in the retracted position in the housing 16 of the housing 12, it is difficult to grasp it manually to then rotate it to its deployed position. This is why the key 10 includes means for driving the rod 14 from its retracted position to an intermediate position, in which a part of the rod 14 extends outside the housing 16. [035 There is shown in Figures 1 to 2D a first embodiment of the invention according to which the rod drive means 14 comprise a drive finger 36 secured to the locking element 22, and which is adapted to cooperate with the heel 18 of the rod 14. [036] Here, the drive finger 36 bears against a vertical support face 38 of the heel 18, which extends radially relative to the axis 20 of articulation, to drive the rod 14. [037] When the locking element 22 is in the locking position, as can be seen in FIG. 2, the drive finger 36 extends at a distance from the face of support 38. This clearance "j" which is present between the drive finger 36 and the support face allows the worm finger rusting 24 to come out of the first notch 26, before the locking element 22 drives the rod 14. [038] According to a preferred embodiment of the invention, the vertical support face 38 is a portion of the second notch 28. [039] The locking element 22 is mounted movable relative to the housing 12 in translation in a horizontal transverse direction, and it comprises a part 40 of generally cylindrical shape, of transverse main axis, which is guided in translation in a complementary transverse housing 42 of the housing 12. [040] To exit the rod 14 from its retracted position towards its deployed position, in a first movement shown in FIG. 2A, the user of the key 10 acts on the operating element 30 to cause movement of the locking element 22 from its locking position, to an intermediate position shown in FIG. 2B. [041] In this intermediate position, the locking finger 24 has come out of the first notch 26, and the drive finger 36 is in abutment against the bearing face 38 of the heel 18.
[042] Le doigt de verrouillage 24 étant sorti de la première encoche, la tige 14 est alors apte à pivoter par rapport au boîtier 12.[042] The locking finger 24 being removed from the first notch, the rod 14 is then able to pivot relative to the housing 12.
[043] Ensuite, comme on l'a représenté à la figure 2C, l'utilisateur continue d'agir sur l'élément de manœuvre 30 de manière à provoquer un déplacement supplémentaire de l'élément de verrouillage 22, au-delà de la position intermédiaire, jusqu'à ce que l'élément de verrouillage vienne en bout de course, par exemple par la butée de l'élément de manœuvre 30 contre un bord de l'ouverture 32.[043] Then, as shown in FIG. 2C, the user continues to act on the operating element 30 so as to cause additional displacement of the locking element 22, beyond the intermediate position, until the locking element comes to the end of its travel, for example by the stop of the operating element 30 against an edge of the opening 32.
[044] Ce déplacement supplémentaire de l'élément de verrouillage 22 provoque alors le pivotement de la tige 14 autour de l'axe 20, par la coopération du doigt d'entraînement 36 avec la face d'appui 38.[044] This additional movement of the locking element 22 then causes the rod 14 to pivot about the axis 20, by the cooperation of the drive finger 36 with the bearing face 38.
[045] L'utilisateur peut alors relâcher l'élément de manœuvre 30, le ressort 34 provoque alors le rappel de l'élément de verrouillage vers sa position de verrouillage, jusqu'à ce que le doigt de verrouillage vienne en butée contre la face cylindrique externe 18e du talon 18.The user can then release the operating element 30, the spring 34 then causes the locking element to return to its locking position, until the locking finger abuts against the face cylindrical outer 18th of the heel 18.
[046] Enfin, l'utilisateur saisit la partie de la tige 14 qui s'étend hors du logement 16, pour faire pivoter manuellement la tige vers sa position déployée d'utilisation représentée à la figure 2D.[046] Finally, the user grasps the part of the rod 14 which extends out of the housing 16, to manually rotate the rod towards its deployed position of use shown in FIG. 2D.
[047] Lors de ce mouvement manuel de la tige 14, la deuxième encoche 28 vient en vis- à-vis du doigt de verrouillage 24, le doigt de verrouillage 24 s'introduit alors dans la deuxième encoche 28, sous l'effort de rappel élastique du ressort 34, réalisant alors le verrouillage de la tige 14 en position déployée.[047] During this manual movement of the rod 14, the second notch 28 comes opposite the locking finger 24, the locking finger 24 is then introduced into the second notch 28, under the force of elastic return of the spring 34, then locking the rod 14 in the deployed position.
[048] Pour faire pivoter la tige 14 depuis sa position déployée vers sa position escamotée, l'utilisateur agit sur l'élément de manœuvre en provoquant le déplacement de l'élément de verrouillage 22 de manière que le doigt de verrouillage 24 sort hors de la deuxième encoche 28.[048] To pivot the rod 14 from its deployed position to its retracted position, the user acts on the operating element by causing the displacement of the locking element 22 so that the locking finger 24 comes out of the second notch 28.
[049] Ensuite, l'utilisateur fait pivoter manuellement la tige 14 vers sa position escamotée et il relâche son action sur l'élément de manœuvre, pour permettre au doigt de verrouillage 24 de pénétrer dans la première encoche lorsque la tige 14 est dans sa position escamotée.[049] Then, the user manually rotates the rod 14 to its retracted position and releases its action on the operating element, to allow the locking finger 24 to enter the first notch when the rod 14 is in its retracted position.
[050] On a représenté aux figures 3 à 5E un autre mode de réalisation de l'invention selon laquelle les moyens d'entraînement de la tige 14 comportent un élément élastique d'entraînement 44, qui exerce sur la tige 14 un effort élastique d'entraînement vers une position intermédiaire, lorsque la tige 14 est en position escamotée.FIGS. 3 to 5E show another embodiment of the invention according to which the means for driving the rod 14 comprise an elastic drive element 44, which exerts on the rod 14 an elastic force d drive to an intermediate position, when the rod 14 is in the retracted position.
[051] Ainsi, après que l'utilisateur a agit sur l'élément de verrouillage 22, de manière à provoquer la sortie du doigt de verrouillage 4 hors de la première encoche 26, l'élément d'entraînement 44 provoque automatiquement la sortie d'une partie de la tige 14.[051] Thus, after the user has acted on the locking element 22, so as to cause the locking finger 4 to exit from the first notch 26, the element drive 44 automatically causes part of the rod 14 to exit.
[052] L'utilisateur peut alors saisir la tige 14 pour la faire pivoter vers sa position déployée.[052] The user can then grasp the rod 14 to rotate it to its deployed position.
[053] Ici, comme on peut le voir à la figure 3, l'élément élastique d'entraînement 44 et le ressort de rappel 34 sont deux parties d'un ressort élastique 46 unique, qui est réalisé par découpe et pliage d'une bande métallique.[053] Here, as can be seen in FIG. 3, the elastic drive element 44 and the return spring 34 are two parts of a single elastic spring 46, which is produced by cutting and folding a metal strip.
[054] De plus, l'élément de verrouillage 22 consiste ici en un élément globalement cylindrique d'axe principal vertical, qui est monté coulissant par rapport au boîtier 12 selon une direction globalement verticale dans un logement cylindrique complémentaire du boîtier 12, dont l'axe principal B est décalé par rapport à l'axe 20 d'articulation de la tige 14.[054] In addition, the locking element 22 here consists of a generally cylindrical element with a vertical main axis, which is slidably mounted relative to the housing 12 in a generally vertical direction in a cylindrical housing complementary to the housing 12, the l the main axis B is offset relative to the axis 20 of articulation of the rod 14.
[055] Le doigt de verrouillage 24 s'étend radialement et verticalement le long d'une génératrice verticale de la face cylindrique externe 22e de l'élément de verrouillage 22.[055] The locking finger 24 extends radially and vertically along a vertical generatrix of the external cylindrical face 22e of the locking element 22.
[056] L'élément de verrouillage 22 est monté coulissant par rapport au boîtier 12 entre une position relevée de verrouillage représentée à la figure 5A, et une position basse de déverrouillage représentée à la figure 5B.[056] The locking element 22 is slidably mounted relative to the housing 12 between a raised locking position shown in Figure 5A, and a low unlocking position shown in Figure 5B.
[057] Pour réaliser le déverrouillage lorsque l'élément de verrouillage 22 est en position de déverrouillage, c'est-à-dire pour que le doigt de verrouillage 24 ne coopère pas avec la première encoche 26 ou la deuxième encoche 28, le doigt de verrouillage comporte une entaille 48 qui est traversée par le talon 18 de la tige 14 lors du pivotement de la tige 14 autour de l'axe 20.[057] To perform the unlocking when the locking element 22 is in the unlocking position, that is to say so that the locking finger 24 does not cooperate with the first notch 26 or the second notch 28, the finger of locking comprises a notch 48 which is crossed by the heel 18 of the rod 14 during the pivoting of the rod 14 about the axis 20.
[058] Pour pouvoir actionner manuellement l'élément de verrouillage 22, le logement de guidage 42 de l'élément de verrouillage 22 est débouchant à son extrémité supérieure, de manière que l'extrémité supérieure de l'élément de verrouillage débouche en partie à l'extérieur du boîtier 12 pour pouvoir être actionné manuellement, à la manière d'un bouton poussoir.[058] In order to be able to manually actuate the locking element 22, the guide housing 42 of the locking element 22 opens out at its upper end, so that the upper end of the locking element opens out in part at outside the housing 12 to be able to be actuated manually, in the manner of a push button.
[059] Pour le rappel de l'élément de verrouillage 22 vers sa position de verrouillage, le ressort de rappel 34 a lui aussi la forme d'une lame métallique qui est agencé au- dessous de l'élément de verrouillage, et exerce par conséquent un effort de rappel orienté verticalement vers le haut.[059] For the return of the locking element 22 to its locking position, the return spring 34 also has the form of a metal blade which is arranged below the locking element, and exerts by therefore a return effort oriented vertically upwards.
[060] On a représenté aux figures 5A à 5E les différentes étapes de fonctionnement de la clé 10.FIGS. 5A to 5E show the different stages of operation of the key 10.
[061] La figure 5 A représente la tige 14 dans son état initial, c'est-à-dire lorsqu'elle est repliée dans le logement ls.[061] Figure 5 A shows the rod 14 in its initial state, that is to say when it is folded into the housing ls.
[062] Selon un premier mouvement représenté à la figure 5B, l'utilisateur presse sur l'élément de verrouillage 22, de manière à le déplacer vers le bas, jusqu'à ce que l'entaille 48 soit à la hauteur du talon 18.[062] In a first movement shown in Figure 5B, the user presses on the locking element 22, so as to move it down, until the notch 48 is at the height of the heel 18 .
[063] La tige 14 n'est alors plus bloquée en pivotement, la lame 44 l'entraîne donc à l'extérieur du logement 16, comme on l'a représenté à la figure 5C. [064] Ensuite, comme on peut le voir à la figure 5D, l'utilisateur entraîne manuellement la tige 14 vers sa position déployée, c'est-à-dire jusqu'à ce que la deuxième encoche 28 vienne en vis-à-vis du doigt d'arrêt 24. [065] Alors, comme on peut le voir à la figure 5E, et dans un dernier mouvement, l'élément de verrouillage 22 est entraîné vers le haut par le ressort de rappel 34, de manière que le doigt d'arrêt 24 soit reçu dans la deuxième encoche 28, réalisant ainsi le verrouillage de la tige 14 dans sa position déployée. [066] Pour faire pivoter la tige 14 depuis sa position déployée vers sa position escamotée, l'utilisateur agit d'abord sur l'élément de verrouillage 22 de manière à le déplacer vers le bas, jusqu'à ce que l'entaille 48 soit à la hauteur du talon 18. [067] Ensuite, l'utilisateur fait pivoter manuellement la tige 14 vers sa position escamotée, à l'encontre de l'effort élastique de rappel de la lame 44, puis il relâche son action sur l'élément de verrouillage 22. [068] Le doigt de verrouillage 24 est alors apte à pénétrer de nouveau dans la première encoche 26, réalisant ainsi le verrouillage de la tige en position escamotée. [069] Une telle clé 10 comporte ainsi un nombre relativement de composants pour l'entraînement de la tige vers sa position déployée. [070] Ce faible nombre de composants permet d'agencer ces composants dans une partie d'une seule demi-coquille du boîtier 12, mettant une plus grande partie du volume intérieur du boîtier disponible pour agencer le dispositif électronique. [071] De plus, ce faible nombre de composants simplifie la fabrication de la clé 10, aussi bien en ce qui concerne la conception des différents composants, qu'en ce qui concerne leur assemblage. [072] Le coût de réalisation de la clé est par conséquent lui aussi réduit.[063] The rod 14 is then no longer pivotally blocked, the blade 44 therefore causes it to the exterior of the housing 16, as shown in FIG. 5C. [064] Then, as can be seen in FIG. 5D, the user manually drives the rod 14 to its deployed position, that is to say until the second notch 28 comes opposite. screw of the stop finger 24. [065] Then, as can be seen in FIG. 5E, and in a last movement, the locking element 22 is driven upwards by the return spring 34, so that the stop finger 24 is received in the second notch 28, thus realizing the locking of the rod 14 in its deployed position. [066] To pivot the rod 14 from its deployed position to its retracted position, the user first acts on the locking element 22 so as to move it downwards, until the notch 48 or at the height of the heel 18. [067] Next, the user manually rotates the rod 14 towards its retracted position, against the elastic return force of the blade 44, then releases its action on the 'locking element 22. [068] The locking finger 24 is then able to penetrate again into the first notch 26, thus realizing the locking of the rod in the retracted position. [069] Such a key 10 thus comprises a relatively number of components for driving the rod towards its deployed position. This low number of components makes it possible to arrange these components in a part of a single half-shell of the housing 12, putting a greater part of the interior volume of the housing available to arrange the electronic device. [071] In addition, this low number of components simplifies the manufacture of the key 10, both with regard to the design of the various components, as regards their assembly. The cost of producing the key is therefore also reduced.
[073] Enfin, malgré le fait que le mécanisme d'entraînement conforme au deuxième aspect de l'invention est plus encombrant verticalement, il est aussi plus simple d'utilisation. [074] En effet, l'actionnement de l'élément de verrouillage 22 ne s'effectue que par une pression verticale, de la même manière que l'utilisateur presse sur l'un des boutons du dispositif électronique. [073] Finally, despite the fact that the drive mechanism according to the second aspect of the invention is more bulky vertically, it is also easier to use. [074] Indeed, the actuation of the locking element 22 is effected only by vertical pressure, in the same way as the user presses on one of the buttons of the electronic device.
