  • FIG. 5 is a top view, partially broken away, of the assembly illustrated in FIG. 4.

La clef 10 illustrée sur la figure 1 est pour l'essentiel constituée par un corps de clef métallique 11 de forme générale allongée et dont l'extrémité libre 12, opposée à l'extrémité de la clef (non représentée) prévue pour être introduite dans un corps de verrou, présente une forme générale parallélépipédique rectangle qui s'étend dans un plan général parallèle à ses grandes faces 14 et parallèle à la direction longitudinale du corps de clef 11.The key 10 illustrated in FIG. 1 is essentially constituted by a metal key body 11 of generally elongated shape and the free end 12 of which, opposite the end of the key (not shown) intended to be introduced into a lock body, has a generally rectangular parallelepiped shape which extends in a general plane parallel to its large faces 14 and parallel to the longitudinal direction of the key body 11.

La clef 10 comporte également une tête de préhension 16 qui, dans le mode de réalisation illustré sur les figures, est constituée par un boîtier de commande à distance d'un système centralisé pour l'ouverture et la fermeture des portes et ouvrants d'un véhicule automobile.The key 10 also includes a gripping head 16 which, in the embodiment illustrated in the figures, is constituted by a remote control unit of a centralized system for the opening and closing of the doors and openings of a motor vehicle.

Selon une conception connue, le boîtier formant tête de préhension 16 (figures 4 et 5) est pour l'essentiel constitué par deux demi-boîtiers en matière plastique 18 et 20 reliés entre eux selon un plan de joint médian 22 et qui délimitent une chambre interne 24 qui reçoit notamment des piles 26, un circuit électronique de commande 28 et des commutateurs 30 commandés par des boutons 32 qui font saillie dans la face supérieure du demi-boîtier 18.According to a known design, the housing forming gripping head 16 (FIGS. 4 and 5) is essentially constituted by two plastic half-housings 18 and 20 connected together according to a median joint plane 22 and which delimit a chamber internal 24 which receives in particular batteries 26, an electronic control circuit 28 and switches 30 controlled by buttons 32 which project into the upper face of the half-housing 18.

A son extrémité avant 34, le boîtier 16 comporte un logement ouvert 36 de forme générale parallélépipédique rectangle dont la face ouverte de contour rectangulaire s'ouvre dans la face d'extrémité avant 34 du boîtier 16.At its front end 34, the box 16 comprises an open housing 36 of generally rectangular parallelepiped shape, the open face of rectangular outline opens in the front end face 34 of the box 16.

Le logement borgne 36 est délimité par un fond transversal 38 par deux petites faces latérales parallèles et opposées 40 et 42 ainsi que par deux grandes faces latérales parallèles et opposées 44 et 46.The blind housing 36 is delimited by a transverse bottom 38 by two small parallel and opposite lateral faces 40 and 42 as well as by two large parallel and opposite lateral faces 44 and 46.

Comme cela est représenté de manière plus précise sur la figure 4, les grandes faces latérales opposées 44 et 46 qui, en position montée du corps de clef 11, sont parallèles au plan des grandes faces 14 de ce dernier, comportent chacune une cavité concave arrondie dont l'axe est perpendiculaire à la direction longitudinale du corps 11.As shown more precisely in FIG. 4, the large opposite lateral faces 44 and 46 which, in the mounted position of the key body 11, are parallel to the plane of the large faces 14 of the latter, each have a rounded concave cavity whose axis is perpendicular to the longitudinal direction of the body 11.

Le fond 38 comporte une rainure 48 parallèle au plan général du corps de clef 11 qui se prolonge par une rainure 50 formée dans la petite face latérale 42.The bottom 38 has a groove 48 parallel to the general plane of the key body 11 which is extended by a groove 50 formed in the small lateral face 42.

Les rainures 48 et 50 sont toutes les deux situées dans un plan sensiblement médian du logement 36 qui est parallèle au plan général du corps de clef 11.The grooves 48 and 50 are both located in a substantially median plane of the housing 36 which is parallel to the general plane of the key body 11.

Afin de lui conférer une élasticité suffisante, la paroi supérieure 52 dont la face interne constitue la grande face latérale 46 du logement 36 est d'épaisseur réduite.In order to give it sufficient elasticity, the upper wall 52 whose internal face constitutes the large lateral face 46 of the housing 36 is of reduced thickness.

Le logement 36 qui vient d'être décrit en détail est prévu pour recevoir la portion d'extrémité 54 du corps de clef 11 qui est constitué par une pièce moulée en matière plastique rapportée sur ce dernier.The housing 36 which has just been described in detail is intended to receive the end portion 54 of the key body 11 which is constituted by a molded plastic part attached to the latter.

Le corps moulé 56 de la pièce 54 comporte, dans sa face arrière 58 opposée au logement 36 un réceptacle 60 de forme parallélélipédique rectangle qui reçoit l'extrémité de forme complémentaire 12 du corps de clef 11.The molded body 56 of the part 54 comprises, in its rear face 58 opposite the housing 36 a receptacle 60 of rectangular parallelepiped shape which receives the end of complementary shape 12 of the key body 11.

Dans l'exemple représenté, la solidarisation de la pièce 54 sur le corps de clef 11 est assurée au moyen d'une goupille transversale 64 qui traverse la pièce 54 et l'extrémité 12 du corps de clef 11. Cette solidarisation peut également être réalisée par surmoulage de la pièce 54 sur la clef 11.In the example shown, the attachment of the piece 54 to the key body 11 is ensured by means of a transverse pin 64 which passes through the piece 54 and the end 12 of the key body 11. This attachment can also be achieved by overmolding of the part 54 on the key 11.

La pièce 54 est délimitée par une face transversale d'extrémité 66 qui est sensiblement plane et perpendiculaire à la direction longitudinale du corps de clef 11, par deux petites faces latérales opposées 68 et 70, et par deux grandes faces latérales opposées 72 et 74.The part 54 is delimited by a transverse end face 66 which is substantially planar and perpendicular to the longitudinal direction of the key body 11, by two opposite small side faces 68 and 70, and by two opposite large side faces 72 and 74.

La face transversale d'extrémité 66 comporte une nervure 76 prévue pour être reçue dans la rainure 48 du logement 36 tandis que la petite face latérale 68 comporte une nervure 78 qui prolonge la nervure 76 et qui est prévue pour être reçue dans la rainure 50 du logement 36.The transverse end face 66 comprises a rib 76 intended to be received in the groove 48 of the housing 36 while the small lateral face 68 comprises a rib 78 which extends the rib 76 and which is intended to be received in the groove 50 of the housing 36.

Chacune des grandes faces latérales 72 et 74 comporte un renflement arrondi dont l'axe est perpendiculaire à la direction longitudinale du corps de clef 11 et qui est prévu pour coopérer avec les cavités correspondantes formées dans les grandes faces latérales 46 et 44 du logement 36.Each of the large lateral faces 72 and 74 has a rounded bulge whose axis is perpendicular to the longitudinal direction of the key body 11 and which is designed to cooperate with the corresponding cavities formed in the large lateral faces 46 and 44 of the housing 36.

L'assemblage du corps de clef 11 dans le logement 36 de la tête de préhension 16, après avoir assemblé les différents composants de cette dernière, s'effectue en emboîtant élastiquement la portion d'extrémité 54 solidaire du corps de clef 11 dans le logement 36 en exerçant un effort de poussée sur le corps de clef 11 selon la direction de la flèche F de la figure 1.The assembly of the key body 11 in the housing 36 of the gripping head 16, after having assembled the various components of the latter, is carried out by elastically fitting the end portion 54 integral with the key body 11 in the housing 36 by exerting a pushing force on the key body 11 in the direction of the arrow F in FIG. 1.

Cet effort de poussée a pour effet de provoquer une déformation élastique de la paroi 52 du logement 36 jusqu'à ce que les renflements des faces latérales 72 et 74 de la pièce 54 pénètrent dans les cavités arrondies 46 et 44 du logement 56 pour venir occuper la position montée illustrée à la figure 4 dans laquelle les nervures 76 et 78 sont en outre en position dans les rainures 48 et 50.This pushing force has the effect of causing an elastic deformation of the wall 52 of the housing 36 until the bulges of the lateral faces 72 and 74 of the part 54 penetrate into the rounded cavities 46 and 44 of the housing 56 to occupy it. the mounted position illustrated in FIG. 4 in which the ribs 76 and 78 are also in position in the grooves 48 and 50.

Dans la position assemblée illustrée à la figure 4, le corps de clef 11 est ainsi parfaitement solidarisé de la tête de préhension 16 et la clef peut être utilisée comme n'importe quelle clef de contact.In the assembled position illustrated in Figure 4, the key body 11 is thus perfectly secured to the gripping head 16 and the key can be used like any ignition key.

En cas de choc accidentel sur la tête de préhension 16, lorsque la clef est en position dans le dispositif antivol, il se produit un déboîtement automatique de la portion 54 hors du logement 36 qui est favorisé par les formes complémentaires arrondies de la portion 54 et du logement 56.In the event of accidental impact on the gripping head 16, when the key is in position in the anti-theft device, there is an automatic disengagement of the portion 54 from the housing 36 which is favored by the rounded complementary shapes of the portion 54 and housing 56.

Ce phénomène de déboîtement permet ainsi la désolidarisation automatique de la tête de préhension 16 du corps de clef 11 évitant ainsi toute blessure ou meurtrissure pour le corps du conducteur.This dislocation phenomenon thus allows the automatic separation of the gripping head 16 from the key body 11, thus avoiding any injury or bruising for the body of the driver.

Après la désolidarisation des deux éléments par déboîtement élastique, il est possible de remettre en place la tête de préhension 16 sur l'extrémité du corps de clef 11 en venant à nouveau emboîter élastiquement la pièce d'extrémité 54 dans le logement 36.After the two elements have been detached by elastic disengagement, it is possible to replace the gripping head 16 on the end of the key body 11 by coming again to resiliently fit the end piece 54 into the housing 36.
