Ensuite, après avoir inséré le ressort et le capuchon par un orifice prévu dans la paroi de dessus, il est nécessaire de fixer la demi-coquille de dessus pour que le mécanisme d'éjection soit fonctionnel. Le nombre de pièces du mécanisme d'éjection et le nombre d'étapes d'assemblage sont donc élevés.This device of the prior art has several disadvantages. Firstly, when assembling the ejection mechanism, it is necessary to pre-assemble the pin and the pivot piece to insert them together between the bottom wall and the top wall of the housing, and then to push the pin so as to plug it into a housing formed in the bottom wall. Then, after inserting the spring and the cap through a hole provided in the top wall, it is necessary to fix the top half-shell for the ejection mechanism is functional. The number of parts of the ejection mechanism and the number of assembly steps are therefore high.

L'invention a pour but de fournir un dispositif à clé escamotable qui ne présente pas au moins certains des inconvénients précités de l'art antérieur, et un procédé d'assemblage correspondant. En particulier, l'invention vise à fournir un dispositif à clé escamotable simplifié, dont le mécanisme d'éjection de clé ne nécessite qu'un nombre réduit de pièces et/ou d'étapes d'assemblage.The invention aims to provide a retractable key device that does not have at least some of the aforementioned drawbacks of the prior art, and a corresponding assembly method.

The pivot 5 has an inner housing 15 which has the side facing the bottom wall 3 a bottom opening 16 and a top opening 17 facing towards the top wall 17. The top opening 17 is substantially circular and comprises two pivot notches 22. At the bottom opening 16, the housing The inner housing 15 has a shoulder defining a pivot bearing surface 18.

Le mécanisme d'éjection de clé comprend également un bouton 10 de forme globalement cylindrique. Le bouton 10 comprend deux tenons 23 latéraux, diamétralement opposés, qui définissent des surfaces d'indexation de bouton 20. Le bouton 10 présente aussi un épaulement circulaire qui définit une surface d'appui de bouton 19. Le bouton 10 est agencé partiellement dans le logement intérieur 15 du pivot 5 et partiellement dans l'orifice de bouton 11 du boîtier 2. Les tenons 23 coopèrent avec les encoches de pivot 22 pour lier le bouton 10 et le pivot 5 en rotation, tout en autorisant un déplacement relatif axial du bouton 10 par rapport au pivot 5. Le déplacement axial du bouton 10 par rapport au pivot 5 est limité par l'arrivée en butée de la surface d'appui de bouton 19 contre la surface d'appui de pivot 18.The key ejection mechanism also includes a button 10 of generally cylindrical shape. The button 10 comprises two diametrically opposite lateral pins 23 which define button indexing surfaces 20. The button 10 also has a circular shoulder which defines a button bearing surface 19. The button 10 is arranged partially in the inner housing 15 of the pivot 5 and partially in the button hole 11 of the housing 2. The pins 23 cooperate with the pivot notches 22 to link the knob 10 and the pivot 5 in rotation, while allowing axial relative movement of the button Relative to the pivot 5. The axial displacement of the knob 10 relative to the pivot 5 is limited by the abutment of the button bearing surface 19 against the pivot bearing surface 18.

Le mécanisme d'éjection de clé comprend aussi un ressort 13 hélicoïdal et un axe 12. Le ressort 13 est agencé dans le logement intérieur 15 entre le bouton 10 et l'axe 12. Le ressort est fixé respectivement au bouton 10 et à l'axe 12 par pincement de ses extrémités 29 par des languettes 30 prévues à cet effet. L'axe 12 présente une forme globalement cylindrique et présente deux pattes 25 diamétralement opposées, parallèles à la paroi de fond 3. A l'extrémité de chaque patte 25 se trouve une dent 26 tournée vers la paroi de fond 3. Les dents 26 sont insérées dans les orifices de retenue 27 de la paroi de fond 3 de manière à fixer l'axe 12. L'axe 12 présente une portion de guidage 32 qui coopère avec une surface intérieure du logement intérieur pour guider le pivotement du pivot 5.The key ejection mechanism also comprises a helical spring 13 and an axis 12. The spring 13 is arranged in the inner housing 15 between the button 10 and the axis 12. The spring is fixed respectively to the button 10 and to the pin 12 by pinching its ends 29 by tabs 30 provided for this purpose. The axis 12 has a generally cylindrical shape and has two diametrically opposed lugs 25 parallel to the bottom wall 3. At the end each of the tabs 25 is a tooth 26 facing the bottom wall 3. The teeth 26 are inserted into the retaining apertures 27 of the bottom wall 3 so as to fix the axis 12. The axis 12 has a portion 32 which cooperates with an inner surface of the inner housing to guide the pivoting of the pivot 5.

L'assemblage du dispositif à clé escamotable 1 peut être réalisé de la façon suivante. Le pivot 5 est inséré latéralement dans le boîtier 2, entre la paroi de fond 3 et la paroi de dessus 4, avec les encoches de pivot 22 alignées avec les encoches de boîtier 24 et les encoches d'assemblage 31.The assembly of the retractable key device 1 can be carried out as follows. The pivot 5 is inserted laterally into the housing 2, between the bottom wall 3 and the top wall 4, with the pivot notches 22 aligned with the housing notches 24 and the assembly notches 31.

Ensuite, on insère le bouton 10 dans le logement intérieur 15 du pivot 5 en le faisant passer par l'orifice d'assemblage 14, les tenons 23 passant dans les encoches d'assemblage 31. On poursuit le déplacement du bouton 10 jusqu'à ce que la surface d'appui de bouton 19 arrive en butée contre la surface d'appui de pivot 18. Dans cette position, les tenons 23 coopèrent d'une part avec les encoches de pivot 22 pour lier le pivot 5 et le bouton 10 en rotation, et d'autre part avec les encoches de boîtier 24 pour lier le boîtier 2 et le bouton 10 en rotation.Then, the button 10 is inserted into the inner housing 15 of the pivot 5 by passing it through the assembly hole 14, the studs 23 passing through the assembly notches 31. The movement of the button 10 is continued. that the button bearing surface 19 abuts against the pivot bearing surface 18. In this position, the pins 23 cooperate on the one hand with the pivot notches 22 to bind the pivot 5 and the button 10 in rotation, and secondly with the housing notches 24 to bind the housing 2 and the knob 10 in rotation.

Ensuite, le ressort 13 est inséré dans le logement intérieur 15 en le faisant passer par l'orifice d'assemblage 14, jusqu'à ce que son extrémité 29 soit fixée au bouton 10 par les languettes 30. Puis, l'autre extrémité 29 du ressort 13 est fixée à l'axe 12 qui est inséré partiellement dans le logement intérieur 15 en passant par l'orifice d'assemblage 14, les pattes 25 passant par les encoches d'assemblage 31, jusqu'à ce que les pattes 25 et les dents 26 se trouvent dans la portion élargie 28 du logement intérieur 15. Dans cette position, le ressort 13 est comprimé axialement et il est possible de faire tourner l'axe 12 sur lui-même de manière à contraindre le ressort 13 en torsion. Quand le ressort 13 est suffisamment contraint, par exemple après un quart de tour ou plus, et que les dents 26 sont en regard des orifices de retenue 27, l'axe 12 est relâché, le ressort 13 pousse l'axe 12 vers la paroi de fond 3 et les dents 26 s'insèrent dans les orifices de retenue 27 de manière à fixer l'axe 12 au boîtier 2.Then, the spring 13 is inserted into the inner housing 15 by passing it through the assembly hole 14, until its end 29 is attached to the button 10 by the tabs 30. Then, the other end 29 of the spring 13 is fixed to the axis 12 which is inserted partially into the inner housing 15 through the assembly hole 14, the tabs 25 passing through the assembly notches 31, until the tabs 25 and the teeth 26 are in the enlarged portion 28 of the inner housing 15. In this position, the spring 13 is compressed axially and it is possible to rotate the shaft 12 on itself so as to constrain the spring 13 in torsion . When the spring 13 is sufficiently constrained, for example after a quarter turn or more, and the teeth 26 are opposite the retaining holes 27, the axis 12 is released, the spring 13 pushes the axis 12 towards the wall 3 and the teeth 26 fit into the retaining holes 27 so as to fix the axis 12 to the housing 2.

On obtient alors un dispositif à clé escamotable 1 fonctionnel, dont le fonctionnement est expliqué ci-dessous. Bien entendu, avant ou après les étapes d'assemblage décrites ci-dessus, les éléments électroniques appropriés sont insérés dans le logement de télécommande 8.A functional retractable key device 1 is thus obtained, the operation of which is explained below. Of course, before or after the assembly steps described above, the appropriate electronic elements are inserted into the remote control housing 8.

Le fonctionnement du dispositif à clé escamotable 1 est le suivant. Quand le pivot 5 se trouve dans une position dans laquelle l'insert de clé 9 est escamoté dans le logement d'insert 7, et que l'utilisateur relâche le bouton 10, le ressort 13 pousse le bouton 10 à distance de l'axe 12 de sorte que la surface d'appui du bouton 19 vient en butée contre la surface d'appui du pivot 18. Dans cette position, dite position neutre du bouton 10, les tenons 23 coopèrent avec les encoches de boîtier 24 de manière à empêcher une rotation du bouton 10 par rapport au boîtier 2. Le pivot 5, qui est solidaire en rotation du bouton 10, est donc maintenu dans sa position et l'utilisateur peut par exemple conserver le dispositif à clé escamotable 1 dans sa poche.The operation of the retractable key device 1 is as follows. When the pivot 5 is in a position in which the key insert 9 is retracted into the insert housing 7, and the user releases the button 10, the spring 13 pushes the button 10 away from the axis 12 so that the support surface of the button 19 abuts against the support surface of the pivot 18. In this position, said neutral position of the button 10, the pins 23 cooperate with the housing notches 24 so as to prevent a rotation of the knob 10 relative to the housing 2. The pivot 5, which is integral in rotation with the knob 10, is thus maintained in its position and the user can for example keep the retractable key device 1 in his pocket.

Si l'utilisateur appuie sur le bouton 10 de manière à l'enfoncer vers la paroi de fond 3 jusqu'à ce que les tenons 23 sortent des encoches de boîtier 24, alors le ressort 13 fait tourner le bouton 10, et donc le pivot 5 et l'insert de clé 9, par rapport à l'axe 12 et au boîtier 2, jusqu'à ce que le pivot arrive dans une position définie par une surface de butée non représentée, dans laquelle l'insert de clé 9 est sorti. Cette position correspond à une rotation d'un demi-tour du pivot 5. Les tenons 23 se retrouvent donc de nouveau face à face avec les encoches de boîtier 24 de sorte que si l'utilisateur relâche le bouton 10, alors le ressort 13 pousse les tenons 23 dans les encoches 24 du boîtier, ce qui permet de maintenir l'insert de clé en position sortie.If the user presses the button 10 so as to push it towards the bottom wall 3 until the studs 23 come out of the housing notches 24, then the spring 13 rotates the button 10, and thus the pivot 5 and the key insert 9, with respect to the axis 12 and the housing 2, until the pivot arrives in a position defined by an abutment surface, not shown, in which the key insert 9 is got out. This position corresponds to a rotation of a half turn of the pivot 5. The tenons 23 are thus found again face to face with the housing notches 24 so that if the user releases the button 10, then the spring 13 pushes the tenons 23 in the notches 24 of the housing, which keeps the key insert in the extended position.

De manière similaire, l'utilisateur peut appuyer sur le bouton 10, déplacer manuellement l'insert de clé 9, à l'encontre de l'action du ressort 13, dans le logement d'insert 7, et relâcher le bouton 10 pour maintenir l'insert de clé dans le logement d'insert 7.Similarly, the user can press the button 10, manually move the key insert 9, against the action of the spring 13, in the insert housing 7, and release the button 10 to maintain the key insert in the insert housing 7.

Alternativement au mode de réalisation qui vient d'être décrit, un dispositif à clé escamotable peut par exemple présenter une fixation de l'axe à la paroi de fond différente, une liaison en rotation du pivot et du bouton différente, une indexation du bouton par rapport au boîtier différente,... Le ressort pourrait être pré-assemblé avec le bouton et/ou l'axe, afin de faciliter la fixation de ses extrémités par les languettes.Alternatively to the embodiment just described, a retractable key device may for example have an attachment of the axis to the different bottom wall, a rotation connection of the pivot and the different button, a button indexing by compared to the different housing, ... The spring could be pre-assembled with the button and / or the axis, to facilitate the fixing of its ends by the tabs.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention revendiquée.Although the invention has been described in connection with a particular embodiment, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the claimed invention.
