Des clés de véhicule sont généralement connues. Elles sont notamment destinées par exemple à verrouiller ou à déverrouiller des ouvrants du véhicule, par exemple des portes, commander un hayon, un antivol et/ou un démarreur du véhicule.Vehicle keys are generally known. They are intended for example to lock or unlock the opening of the vehicle, for example doors, control a tailgate, a lock and / or a starter of the vehicle.

Par ailleurs, des clés de véhicule sont connues, notamment d'après la demande de brevet française FR 2 815 521 A1 , qui comprennent un corps de clé et un panneton monté sur ce corps de clé de façon à être capable de pivoter autour d'un axe de rotation, d'une part, entre une position d'utilisation, et d'autre part, une position de rangementMoreover, vehicle keys are known, in particular according to the French patent application FR 2 815 521 A1 , which comprise a key body and a bit mounted on said key body so as to be able to pivot about an axis of rotation, on the one hand, between a position of use, and on the other hand, a storage position

Habituellement, le corps de la clé forme un boîtier pour des moyens électroniques de télécommande de moyens de verrouillage des ouvrants du véhicule. Le corps de la clé peut présenter des formes variées dépendant notamment de l'effet esthétique recherché.Usually, the body of the key forms a housing for electronic means remote control locking means of the opening of the vehicle. The body of the key may have various shapes depending in particular on the desired aesthetic effect.

Un inconvénient de telles clés, selon l'art connu, consiste dans la nécessité de prévoir des éléments de renforcement pour garantir que le panneton reste dans sa position d'utilisation malgré le fait qu'une force mécanique considérable soit appliquée, par exemple le poids d'un porte-clé lorsque la clé est positionnée dans le barillet de démarrage de la voiture.A disadvantage of such keys, according to the prior art, is the need to provide reinforcing elements to ensure that the bit remains in its position of use despite the fact that a considerable mechanical force is applied, for example the weight a key ring when the key is positioned in the car's starter barrel.

La présente invention a notamment pour but de palier aux inconvénients de l'art connu, et notamment ceux cités ci-dessus, et a également pour but de proposer un module mécanique pour une clé d'un véhicule ainsi qu'une clé qui permet de réaliser la clé de véhicule de manière peu coûteuse, de très petite taille, et de manière robuste.The present invention is intended in particular to overcome the drawbacks of the prior art, particularly those mentioned above, and also aims to provide a mechanical module for a vehicle key and a key that allows realize the vehicle key inexpensively, of very small size, and robustly.

Suivant l'invention, ce but est atteint par un module mécanique pour clé comportant un corps de clé et un panneton monté sur ce corps de clé de façon à être capable de pivoter autour d'un axe de rotation entre une position d'utilisation et une position de rangement, le module mécanique étant du type comprenant un support pivotant, portant le panneton et coopérant avec un bouton de commande, le bouton de commande comportant un premier moyen mécanique d'immobilisation en rotation capable de coopérer avec un deuxième moyen mécanique d'immobilisation en rotation d'un élément de boîtier du corps de clé, le bouton de commande étant capable d'être positionné dans une position normale et dans une position enfoncée de manière parallèle à l'axe de rotation, le premier moyen mécanique coopérant avec le deuxième moyen mécanique au moins à quatre endroits autour de l'axe de rotation lorsque le bouton de commande est dans sa position normale.According to the invention, this object is achieved by a mechanical key module comprising a key body and a bit mounted on the key body so as to be able to pivot about an axis of rotation between a position of use. and a storage position, the mechanical module being of the type comprising a pivoting support, carrying the bit and cooperating with a control button, the control button comprising a first mechanical means of immobilization in rotation capable of cooperating with a second mechanical means immobilization in rotation of a body member of the key body, the control knob being capable of being positioned in a normal position and in a depressed position parallel to the axis of rotation, the first cooperating mechanical means with the second mechanical means at least four places around the axis of rotation when the control knob is in its normal position.

Ainsi, il est avantageusement possible de réaliser l'ensemble de la clé de véhicule et notamment le module mécanique d'une manière très solide. Une force qui tend à pivoter le panneton lorsque le bouton de commande est dans sa position normale peut être absorbée à au moins quatre endroits autour de l'axe de rotation ce qui permet d'obtenir une solidité augmentée de l'immobilisation en rotation entre le panneton d'une part et le corps de clé d'autre part lorsque le bouton de commande n'est pas enfoncé.Thus, it is advantageously possible to make the whole of the vehicle key and in particular the mechanical module in a very solid manner. A force that tends to pivot the bit when the control knob is in its normal position can be absorbed at at least four locations around the axis of rotation which provides increased strength of immobilization in rotation between the bit on the one hand and the key body on the other hand when the button is not pressed.

Un perfectionnement préféré de l'invention réside dans le fait que le deuxième moyen mécanique d'immobilisation en rotation est positionné autour d'une ouverture de l'élément de boîtier.A preferred improvement of the invention lies in the fact that the second mechanical means of immobilization in rotation is positioned around an opening of the housing element.

Un autre perfectionnement préféré de l'invention réside dans le fait que le deuxième moyen mécanique d'immobilisation en rotation de l'élément de boîtier est prévu de manière intégrée avec l'élément de boîtier, et comprenant notamment le même matériau que l'élément de boîtier.Another preferred development of the invention lies in the fact that the second mechanical means for immobilizing the housing element in rotation is provided in an integrated manner with the housing element, and comprising in particular the same material as the element. of housing.

Ainsi, il est avantageusement possible de réduire le coût de revient du module mécanique et de la clé de véhicule car le deuxième moyen mécanique d'immobilisation en rotation peut être réalisé en plastique.Thus, it is advantageously possible to reduce the cost of the mechanical module and the vehicle key because the second mechanical means of immobilization in rotation can be made of plastic.

Selon un autre mode de réalisation préféré, le bouton de commande est rappelé élastiquement parallèle à l'axe de rotation vers sa position normale.According to another preferred embodiment, the control button is biased resiliently parallel to the axis of rotation towards its normal position.

Un autre perfectionnement préféré de l'invention réside dans le fait que le bouton de commande comporte un troisième moyen mécanique de guidage axial et d'immobilisation en rotation du bouton de commande par rapport au support pivotant, et que le support pivotant comporte un quatrième moyen mécanique de guidage axial et d'immobilisation en rotation du bouton de commande par rapport au support pivotant.Another preferred development of the invention lies in the fact that the control button comprises a third mechanical means for axial guidance and immobilization in rotation of the control knob relative to the pivoting support, and that the pivoting support comprises a fourth means. mechanical axial guide and immobilization in rotation of the control knob relative to the pivoting support.

Ainsi, il est avantageusement possible de réaliser un fonctionnement simple et efficace du module mécanique de la clé.Thus, it is advantageously possible to achieve a simple and effective operation of the mechanical module of the key.

Encore un autre perfectionnement préféré de l'invention réside dans le fait que les troisième et quatrième moyens mécaniques comprennent au moins un coulisseau solidaire du bouton de commande coopérant avec une rainure complémentaire ménagée dans le support pivotant.Yet another preferred development of the invention lies in the fact that the third and fourth mechanical means comprise at least one integral slider of the control knob cooperating with a complementary groove formed in the pivoting support.

Par une telle réalisation, il est avantageusement possible que le mouvement relatif entre le support pivotant d'une part et le bouton de commande d'autre part peut être réalisé de manière simple et très solide en vue d'une période d'utilisation prolongée.By such an embodiment, it is advantageously possible that the relative movement between the pivoting support on the one hand and the control button on the other hand can be achieved in a simple and very solid manner for a prolonged period of use.

Selon un autre mode de réalisation préféré, le module comprend des moyens de limitation de la course axiale du bouton de commande parallèle à l'axe de rotation.According to another preferred embodiment, the module comprises means for limiting the axial stroke of the control button parallel to the axis of rotation.

Ainsi, il est avantageusement possible de limiter la plage sur laquelle le bouton de commande peut être enfoncé.Thus, it is advantageously possible to limit the range on which the control button can be depressed.

Par ailleurs, la présente invention concerne également une clé, notamment une clé de véhicule, la clé comprenant un module mécanique selon la présente invention.Furthermore, the present invention also relates to a key, in particular a vehicle key, the key comprising a mechanical module according to the present invention.
