Description

La présente invention concerne un boîtier de clé, notamment pour véhicule automobile, présentant une clé, notamment de secours, comprenant d'une part, une tête de clé et un insert et d'autre part, un logement d'insert pour recevoir l'insert en cas de non-utilisation de la clé.The present invention relates to a key box, especially for a motor vehicle, having a key, including a key, comprising firstly, a key head and an insert and secondly, an insert housing for receiving the insert in case of non-use of the key.

Dans le domaine l'automobile, on connaît, par exemple, du document EP 0 987 389 au nom de la Demanderesse, des boîtiers de clé comprenant une partie électronique servant à l'identification par échange de signaux électromagnétiques d'un utilisateur du véhicule et une partie mécanique enfermant une clé de secours.In the automotive field, there is known, for example, from EP 0 987 389 in the name of the Applicant, key housings comprising an electronic part serving for the identification by exchange of electromagnetic signals of a user of the vehicle and a mechanical part enclosing a spare key.

De tels boîtiers sont particulièrement pratiques car ils permettent de dissimuler la clé dans la structure même du boîtier qui la protège. Ceci est très avantageux, car l'utilisateur n'a besoin de cette clé de secours qu'en cas de panne électrique, par exemple panne batterie de la partie électronique ou panne batterie du véhicule.Such boxes are particularly practical because they allow to hide the key in the very structure of the housing that protects it. This is very advantageous because the user only needs this backup key in case of power failure, for example battery failure of the electronic part or battery failure of the vehicle.

Cette disposition évite de plus que l'insert de clé ne s'accroche dans les poches de l'utilisateur et n'endommage ses vêtements. Cet arrangement permet, en outre, de réduire de manière significative l'encombrement du boîtier.This arrangement further prevents the key insert from catching in the user's pockets and damaging his clothes. This arrangement also makes it possible to significantly reduce the size of the housing.

Dans le document EP 0 987 389 cité ci-dessus, la clé de secours comporte une tête formant partie de préhension et un insert métallique qui peut être utilisé comme clé mécanique de secours, la tête étant fixée perpendiculairement à l'insert métallique de façon rigide.In the document EP 0 987 389 cited above, the emergency key comprises a head forming a gripping part and a metal insert which can be used as a mechanical backup key, the head being fixed perpendicularly to the metal insert rigidly .

Pour loger cette clé de secours, le boîtier comporte le long d'un de ses bords un logement formant fourreau destiné à recevoir l'insert et la tête de clé est encliquetée sur une ouverture correspondante du boîtier.To house this emergency key, the housing comprises along one of its edges a housing forming a sleeve for receiving the insert and the key head is snapped onto a corresponding opening of the housing.

Toutefois, étant donné que le nombre de fonctions réalisées par la partie électronique augmente constamment, ce qui nécessite plus de composants électroniques, il est nécessaire de réduire l'encombrement de l'insert de secours au maximum.However, since the number of functions performed by the electronic part is constantly increasing, which requires more electronic components, it is necessary to reduce the size of the spare insert to the maximum.

De plus, étant donné qu'il n'y a pas de séparation hermétique entre la partie électronique et la partie mécanique, on doit prévoir des moyens d'étanchéité spécifiques, ce qui tend à augmenter le coût du boîtier.In addition, since there is no hermetic separation between the electronic part and the mechanical part, there must be specific sealing means, which tends to increase the cost of the housing.

La présente invention vise à pallier ccs divers inconvénients en proposant un boîtier de clé comportant une clé, notamment de secours, ayant un encombrement réduit.The present invention aims to overcome these various drawbacks by providing a key housing comprising a key, including emergency, having a small footprint.

A cet effet, l'invention propose un boîtier de clé, notamment de véhicule automobile, comprenant :

  • une clé , notamment de secours, comportant, fixés l'un à l'autre, une tête de clé formant partie de préhension et un insert destiné à être inséré dans un verrou, notamment de secours, d'un véhicule en cas d'utilisation, et
  • un logement d'insert de forme longitudinale, destiné à recevoir l' insert en cas de non-utilisation de la clé,
For this purpose, the invention proposes a key case, in particular a motor vehicle, comprising:
  • a key, including a spare, comprising, fixed to one another, a key head forming a gripping portion and an insert intended to be inserted into a lock, in particular of emergency, of a vehicle in case of use, and
  • an insert housing of longitudinal shape, intended to receive the insert in case of non-use of the key,

la clé pouvant être séparée du boîtier en cas d'utilisation,the key can be separated from the case when used,

Les figures 1 à 3 présentent des vues en perspective du boîtier de clé 1 selon l'invention selon divers angles, et sa clé, notamment de secours, 3.Figures 1 to 3 show perspective views of the key housing 1 according to the invention at various angles, and its key, including relief, 3.

La clé, notamment de secours, 3 comporte, fixés l'un à l'autre, une tête de clé 5 formant partie de préhension et un insert 7, présentant un axe longitudinal, destiné à être inséré dans un verrou de secours (non représenté) d'un véhicule en cas d'utilisation.The key, including emergency key 3 comprises, fixed to each other, a key head 5 forming a gripping portion and an insert 7, having a longitudinal axis, intended to be inserted into an emergency lock (not shown ) of a vehicle when used.

La géométrie de l'insert de clé, semblable à une lame allongée, permet de définir une longueur (L), une largeur (1) et une épaisseur (e) de l'insert ainsi que des axes associés s'étendant selon ces différentes directions.The geometry of the key insert, similar to an elongate blade, makes it possible to define a length (L), a width (1) and a thickness (e) of the insert as well as associated axes extending according to these different directions.

Dans l'exemple de réalisation décrit ci-après, l'insert 7 est un insert de secours réalisé sous la forme traditionnelle d'un insert métallique mais, dans un but économique, l'insert peut également être réalisé sous la forme d'un insert plastique.In the embodiment described below, the insert 7 is an emergency insert made in the traditional form of a metal insert but, for economic purposes, the insert can also be made in the form of a plastic insert.

Selon un aspect de l'invention, la tête de clé 5 est fixée à l'insert 7 par une articulation 9.According to one aspect of the invention, the key head 5 is fixed to the insert 7 by a hinge 9.

Ainsi, la tête de clé 5 peut être déplacée entre une position de repos (figure 3) dans laquelle elle est sensiblement parallèle à l'insert de clé 7 et une position d'utilisation (figures 1 et 2) dans iaqueiie elle est sensiblement perpendiculaire à l'axe longitudinal de l'insert de clé 7.Thus, the key head 5 can be moved between a rest position (FIG. 3) in which it is substantially parallel to the key insert 7 and a position of use. (Figures 1 and 2) in iieiie it is substantially perpendicular to the longitudinal axis of the key insert 7.

De préférence, l'axe 11 de pivotement de l'articulation 9 est perpendiculaire à un plan 13 défini par l'axe longitudinal de l'insert et la tête de clé en position d'utilisation.Preferably, the axis 11 of pivoting of the articulation 9 is perpendicular to a plane 13 defined by the longitudinal axis of the insert and the key head in the use position.

Pour plus de commodité pour l'utilisateur et pour conférer une meilleure stabilité à la clé de secours 3, en particulier en position d'utilisation, l'articulation 9 est pourvue de moyens d'indexage (non représentés) des positions de repos et d'utilisation.For convenience for the user and to provide a better stability of the emergency key 3, particularly in the use position, the hinge 9 is provided with indexing means (not shown) of the rest positions and 'use.

Avantageusement, l'articulation 9 comprend un embout plastique 15 surmoulé sur l'extrémité arrière 17 de l'insert et portant deux pions, respectivement 19 et 21, diamétralement opposés.Advantageously, the hinge 9 comprises a plastic tip 15 overmolded on the rear end 17 of the insert and carrying two pins, respectively 19 and 21, diametrically opposed.

L'extrémité arrière 18 de la tête de clé 5 comprend deux parois 23 et 25 parallèles au plan 13 et pourvues d'orifices 27 et 29.The rear end 18 of the key head 5 comprises two walls 23 and 25 parallel to the plane 13 and provided with orifices 27 and 29.

Ces deux parois 23 et 25 enferment l'embout plastique 15.These two walls 23 and 25 enclose the plastic tip 15.

Les deux pions 19 et 21 forment l'axe 11 de pivotement et coopèrent avec les orifices 27 et 29 correspondants de la tête de clé 5.The two pins 19 and 21 form the axis 11 of pivoting and cooperate with the orifices 27 and 29 corresponding to the key head 5.

Comme visible sur les figures 1 et 2, l'axe 11 de pivotement est orthogonal à l'axe longitudinal de l'insert et parallèle à un axe s'étendant sur la largeur (1) de l'insertAs can be seen in FIGS. 1 and 2, the pivot axis 11 is orthogonal to the longitudinal axis of the insert and parallel to an axis extending over the width (1) of the insert

Pour assembler la tête de clé 5 avec l'insert métallique 7, on réalise les parois 23 et 25 avec une épaisseur et un matériau assez souple pour s'écarter légèrement afin de permettre la mise en place de l'embout 15.To assemble the key head 5 with the metal insert 7, the walls 23 and 25 are made with a thickness and a material that is flexible enough to move slightly apart so as to enable the end piece 15 to be fitted.

Selon une autre variante avantageuse non représentée, les parties de l'articulation 9 portées d'une part par la tête de clé 5 et d'autre part par l'insert 7 sont assemblés par encliquetage.According to another advantageous variant not shown, the parts of the articulation 9 carried on the one hand by the key head 5 and on the other by the insert 7 are assembled by snapping.

Pour faciliter la séparation de la clé de secours du boîtier, la tête de clé 7 comporte au niveau de l'articulation 9 une partie concave 31 destinée à coopérer avec un doigt d'un utilisateur.To facilitate the separation of the emergency key from the housing, the key head 7 has at the hinge 9 a concave portion 31 for cooperating with a finger of a user.

En cas de non-utilisation, la clé de secours 3 doit être repliée de façon que la tête de clé 5 et l'insert 7 soient sensiblement parallèles l'un par rapport à l'autre, et être fixée, de préférence, par des moyens d'encliquetage complémentaires portés d'une part par la tête de clé et d'autre part par le boîtier de clé 1, dans ledit boîtier.In case of non-use, the emergency key 3 must be folded so that the key head 5 and the insert 7 are substantially parallel to each other, and preferably fixed by complementary latching means carried on the one hand by the key head and on the other hand by the key housing 1, in said housing.

A cet effet, le boîtier 1 comprend un logement d'insert 33 de forme longitudinale, destiné à recevoir l'insert métallique 7 en cas de non-utilisation de la clé de secours 3. Ce logement 33 est partiellement couvert par la paroi externe 34 du boîtier.For this purpose, the housing 1 comprises an insert housing 33 of longitudinal shape, intended to receive the metal insert 7 in case of non-use of the emergency key 3. This housing 33 is partially covered by the outer wall 34 of the case.

Ainsi qu'on le voit sur la figure 3, lorsque la clé de secours 3, en position de repos, à savoir repliée, est insérée dans son logement dans le boîtier 1, la tête de clé 5 forme une partie de la paroi externe 34 du boîtier 1.As can be seen in FIG. 3, when the emergency key 3, in the rest position, namely folded, is inserted into its housing in the housing 1, the key head 5 forms part of the outer wall 34 of the case 1.

Enfin, le boîtier 1 comporte un logement (non visible) pour l'électronique de communication. Cette électronique de communication comporte par exemple un transpondeur et/ou une télécommande, ou encore une électronique de communication radiofréquence du type mains-libres. Sur les figures, on a représenté à titre d'exemple deux boutons 35 et 37 de télécommande pour la condamnation et décondamnation du véhicule.Finally, the housing 1 comprises a housing (not visible) for the communication electronics. This communication electronics comprises, for example, a transponder and / or a remote control, or a radiofrequency communication electronics of the hands-free type. In the figures, there is shown by way of example two buttons 35 and 37 remote control for the conviction and unlocking of the vehicle.

Avantageusement, le logement pour l'électronique est séparé de façon hermétique du logement de la clé de secours. Ceci peut par exemple être réalisé en soudant de façon étanche deux demi-coques pour former un boîtier après avoir disposé la carte portant les composants électroniques dans une des demi-coques.Advantageously, the housing for the electronics is hermetically separated from the housing of the emergency key. This can for example be achieved by sealingly sealing two half-shells to form a housing after arranging the board carrying the electronic components in one of the half-shells.

L'utilisation du boîtier de clé est simple et agréable pour un utilisateur de véhicule.The use of the key case is simple and enjoyable for a vehicle user.

En effet, lorsque le boîtier 1 et la clé de secours 3 sont assemblés tel que représentés à la figure 3, il suffit de pousser dans la partie concave 31 pour sortir la clé de secours 3. La clé de secours est donc complètement séparée du boîtier 1.Indeed, when the housing 1 and the emergency key 3 are assembled as shown in Figure 3, just push in the concave portion 31 to exit the emergency key 3. The emergency key is completely separated from the housing 1.

Puis, on déploie la tête de clé 5 par rapport à l'insert 7 par simple pivotement autour de l'axe 11 et on peut l'insérer dans un verrou de secours du véhicule et actionner celui-ci.Then, it deploys the key head 5 relative to the insert 7 by simply pivoting about the axis 11 and can be inserted into a backup lock of the vehicle and actuate it.

Les figures 4 et 5 représentent un second mode de réalisation de l'invention pour lequel on a représenté la tête de clé et son insert en position d'utilisation et une partie du boîtier de clé accueillant la tête de clé et son insert en position de repos ou repliée.FIGS. 4 and 5 show a second embodiment of the invention for which the key head and its insert are shown in the use position and a part of the key housing accommodating the key head and its insert in the position of rested or folded.

Les références identiques au premier mode de réalisation sont indiquées par les mêmes numéros.The references identical to the first embodiment are indicated by the same numbers.

Comme visible sur la figure 4, la tête de clé 5 est fixée à l'insert 7, réalisé dans l'exemple décrit sous la forme d'un insert métallique, par l'articulation 9 de sorte que la tête de clé 5 peut être déplacée entre une position de repos dans laquelle elle est sensiblement parallèle à l'insert de clé 7 et une position d'utilisation (figure 4) dans laquelle elle est sensiblement perpendiculaire à l'axe longitudinal de l'insert de clé.As can be seen in FIG. 4, the key head 5 is fixed to the insert 7, made in the example described in the form of a metal insert, by the hinge 9 so that the key head 5 can be moved between a rest position in which it is substantially parallel to the key insert 7 and a position of use (Figure 4) in which it is substantially perpendicular to the longitudinal axis of the key insert.

Dans la position d'utilisation, tout comme dans le premier mode de réalisation représenté aux figures 1 et 2, l'axe 11 de pivotement de l'articulation 9, ou axe d'articulation, est perpendiculaire au plan 13 défini par l'axe longitudinal de l'insert et la tête de clé en position d'utilisation. Cependant, ici, l'axe d'articulation 11 est orthogonal à un axe correspondant à la largeur (1) de l'insert.In the position of use, just as in the first embodiment shown in FIGS. 1 and 2, the axis 11 of pivoting of the articulation 9, or axis of articulation, is perpendicular to the plane 13 defined by the axis length of the insert and the key head in the use position. However, here, the hinge axis 11 is orthogonal to an axis corresponding to the width (1) of the insert.

Cette caractéristique d'agencement de l'axe 11 de pivotement est particulièrement avantageuse car elle permet d'obtenir une grande robustesse de l'articulation 9 formant la liaison insert / tête de clé.This arrangement feature of the axis 11 of pivoting is particularly advantageous because it allows to obtain a high strength of the joint 9 forming the insert connection / key head.

Comme dans le mode de réalisation précédent, l'articulation 9 comprend un embout plastique 15 surmoulé sur l'extrémité arrière 17 de l'insert 7 et portant deux pions, respectivement 19 et 21, diamétralement opposés et formant l'axe 11 de pivotement.As in the previous embodiment, the hinge 9 comprises a plastic tip 15 overmolded on the rear end 17 of the insert 7 and carrying two pins, respectively 19 and 21, diametrically opposed and forming the axis 11 of pivoting.

L'extrémité arrière 17 de la tête de clé 5 comprend deux parois 23 et 25 parallèles au plan 13, enfermant l'embout plastique 15, et pourvues d'orifices 27 et 29 dans lesquels s'engagent respectivement les deux pions 19 et 21.The rear end 17 of the key head 5 comprises two walls 23 and 25 parallel to the plane 13, enclosing the plastic end 15, and provided with orifices 27 and 29 in which engage respectively the two pins 19 and 21.

En cas de non-utilisation, la clé de secours 3 est repliée de sorte que la tête de clé 5 et l'insert 7 sont sensiblement parallèles, l'un par rapport à l'autre et retenu en position de repos par des moyens d'encliquetage complémentaires 20, 22 portés d'une part par la tête de clé et d'autre part par le boîtier de clé, dans le boîtier 1.In case of non-use, the emergency key 3 is folded so that the key head 5 and the insert 7 are substantially parallel, relative to each other and held in the rest position by means of complementary clipping 20, 22 carried on the one hand by the key head and on the other hand by the key housing, in the housing 1.

De façon préférentielle, les parois 23 et 25 s'étendent le long de l'axe longitudinal de la tête de clé 5 et présentent des rainures de positionnement 24 pour assurer un positionnement correct de l'insert 7 lorsque celui-ci est replié parallèlement à la tête de clé en position de repos.Preferably, the walls 23 and 25 extend along the longitudinal axis of the key head 5 and have positioning grooves 24 to ensure correct positioning of the insert 7 when the latter is folded parallel to the key head in the rest position.

L'assemblage de l'insert 7 sur la tête de clé 5 peut être fait de manière semblable à celle décrite dans le cadre du premier mode de réalisation de l'invention.The assembly of the insert 7 on the key head 5 can be done in a manner similar to that described in the context of the first embodiment of the invention.

Comme présenté à la figure 5, lorsque la clé 3 est en position de repos, elle peut être stockée dans le logement d'insert 33 que présente, par exemple, la demi-coque inférieure 36 du boîtier de clé. Ce logement d'insert 33 est de forme longitudinale et est destiné à être partiellement couvert par la paroi externe du boîtier (non représentée) formée par la demi-coque inférieure 36 et la demi-coque supérieure (non représentée) du boîtier lorsque celles-ci sont assemblées.As shown in Figure 5, when the key 3 is in the rest position, it can be stored in the insert housing 33 that has, for example, the lower half-shell 36 of the key housing. This insert housing 33 is of longitudinal shape and is intended to be partially covered by the outer wall of the housing (not shown) formed by the lower half-shell 36 and the upper half-shell (not shown) of the housing when these ci are assembled.

La demi-coque inférieure 36 comporte un logement 32 pour une électronique de communication (non représentée) qui comprend, par exemple, un transpondeur et/ou une télécommande, ou encore une électronique de communication radiofréquence du type mains-libres.The lower half-shell 36 comprises a housing 32 for a communication electronics (not shown) which comprises, for example, a transponder and / or a remote control, or a radio frequency communication electronics of the hands-free type.

Pour faciliter la séparation de la clé de secours du boîtier, la tête de clé 7 comporte, au niveau de l'articulation 9, une partie concave 31 destinée à coopérer avec un doigt d'un utilisateur.To facilitate the separation of the emergency key from the housing, the key head 7 has, at the hinge 9, a concave portion 31 for cooperating with a finger of a user.

Par ailleurs, il est également possible de prévoir au niveau de la tête de clé 5, à son extrémité opposée à l'articulation 9, une encoche de préhension destinée à coopérer avec un doigt d'un utilisateur pour manipuler la tête de clé 5.Furthermore, it is also possible to provide at the key head 5, at its end opposite the articulation 9, a gripping notch intended to cooperate with a finger of a user to manipulate the key head 5.

Un troisième mode de réalisation de l'invention est représenté aux figures 6 à 8 qui montrent respectivement le boîtier avec sa clé de secours en position d'utilisation, la clé de secours en position de repos et la clé de secours en position de repos logée dans la demi-coque inférieure du boîtier de clé.A third embodiment of the invention is shown in Figures 6 to 8 which respectively show the housing with its emergency key in the use position, the emergency key in the rest position and the emergency key in the rest position housed in the lower half-shell of the key case.

Selon un aspect de l'invention, la tête de clé 5 est fixée à l'insert 7, réalisé sous la forme d'un insert métallique ou plastique, par une articulation 10 et la tête de clé 5 peut être déplacée entre une position de repos (figures 7 et 8) dans laquelle elle est sensiblement parallèle à l'axe longitudinal de l'insert de clé 7 et une position d'utilisation (figure 6) dans laquelle elle est sensiblement perpendiculaire à l'axe longitudinal de l'insert de clé 7.According to one aspect of the invention, the key head 5 is fixed to the insert 7, made in the form of a metal or plastic insert, by a hinge 10 and the key head 5 can be moved between a position of rest (Figures 7 and 8) wherein it is substantially parallel to the longitudinal axis of the key insert 7 and a position of use (Figure 6) in which it is substantially perpendicular to the longitudinal axis of the insert of key 7.

Dans la position d'utilisation, l'axe 11 de pivotement de l'articulation 10 est perpendiculaire à un plan 13 défini par l'axe longitudinal de l'insert et la tête de clé en position d'utilisation de sorte que l'axe 11 de pivotement est agencé perpendiculairement à un axe s'étendant sur la largeur (1) de l'insert.In the position of use, the axis 11 of pivoting of the articulation 10 is perpendicular to a plane 13 defined by the longitudinal axis of the insert and the key head in the use position so that the pivot axis 11 is arranged perpendicularly to an axis extending over the width (1) of the insert.

Cette caractéristique d'agencement de l'axe de pivotement est particulièrement avantageuse car elle permet d'avoir une grande robustesse de l'articulation 10 formant la liaison insert / tête de clé.This characteristic of arrangement of the pivot axis is particularly advantageous because it allows a high strength of the joint 10 forming the insert / key head connection.

Dans ce mode de réalisation, l'insert de clé 7 et la tête de clé 5 sont fixés l'un à l'autre par l'articulation 10 qui permet, par sa structure, que l'insert 7 et la tête de clé 5 soient manoeuvrables l'un par rapport à l'autre d'une part, en rotation et d'autre part, en translation.In this embodiment, the key insert 7 and the key head 5 are fixed to each other by the hinge 10 which, by its structure, allows the insert 7 and the key head 5 are maneuverable relative to each other on the one hand, in rotation and on the other hand, in translation.

A cet effet, l'extrémité arrière 17 de l'insert 7 présente un embout surmoulé 15 pourvu de pions 19 et 21 formant l'axe 11 de pivotement de l'articulation 10 et coopérant avec des orifices 27, 29 de la tête de clé 5.For this purpose, the rear end 17 of the insert 7 has an overmolded tip 15 provided with pins 19 and 21 forming the axis 11 of pivoting of the articulation 10 and cooperating with orifices 27, 29 of the key head. 5.

La tête de clé 5 se présente, quant à elle, sous la forme d'une pièce en U 26 de forme longitudinale qui enferme l'extrémité arrière 17 de l'insert 7. Les orifices 27, 29 forment chacun une lumière 28a respectivement 28b qui s'étend selon l'axe longitudinal de la tête de clé 5 de sorte que, en coopération avec les pions 19, 21, ces lumières permettent une translation de l'articulation 10 le long de l'axe longitudinal de la tête de clé 5 en vue de préparer le positionnement de l'insert 7 en position de repos.The key head 5 is, in turn, in the form of a U-shaped piece 26 of longitudinal shape which encloses the rear end 17 of the insert 7. The orifices 27, 29 each form a light 28a respectively 28b which extends along the longitudinal axis of the key head 5 so that, in cooperation with the pins 19, 21, these lights allow translation of the hinge 10 along the longitudinal axis of the key head 5 to prepare the positioning of the insert 7 in the rest position.

De préférence, les mouvements de translation et de rotation de la tête de clé 5 par rapport à l'insert 7 sont réalisés de manière successive c'est à dire qu'il faut d'abord avoir fait glisser la tête de clé 5 de sa position d'utilisation vers une position intermédiaire dans laquelle les pions 19 et 21 se trouvent à l'extrémité arrière 18 de la tête de clé, avant d'effectuer la rotation de la tête de clé 5 vers l'insert 7 en vue de la positionner en position de repos.Preferably, the translational and rotational movements of the key head 5 with respect to the insert 7 are carried out successively, that is to say that the key head 5 of its key must first be slid. use position to an intermediate position in which the pins 19 and 21 are at the rear end 18 of the key head, before rotating the key head 5 to the insert 7 for the purpose of position in the rest position.

On peut également prévoir d'avoir une articulation 10 conformée pour permettre de réaliser les mouvements de translation et de rotation, de la tête de clé 5 par rapport à l'insert 7, de manière simultanée. L'axe 11 de pivotement est donc mobile et se déplace toujours parallèlement à lui-même.It is also possible to have a hinge 10 shaped to allow to perform the translation and rotation movements of the key head 5 relative to the insert 7, simultaneously. The axis 11 of pivoting is mobile and always moves parallel to itself.

Selon un aspect pratique de l'invention, les différentes parties formant l'articulation 10, portées d'une part, par la tête de clé 5 et d'autre part, par l'insert 7, sont assemblées par encliquetage.According to a practical aspect of the invention, the various parts forming the hinge 10, carried on the one hand by the key head 5 and on the other hand by the insert 7, are assembled by snapping.

Lorsque la clé 3 est en position de repos (figure 7), elle peut être logée dans un logement d'insert 33, de forme longitudinale, formé à partir de deux logements réalisés dans chacune des demi-coques du boîtier de clé 1. Ce logement d'insert, une fois les deux demi-coques assemblées, est partiellement couvert par la paroi externe 34 du boîtier de clé 1. La figure 8 présente, plus particulièrement, la clé 3 en position de repos, logée dans une partie du logement d'insert 33 formée dans la demi-coque inférieure 36 du boîtier de clé 1.When the key 3 is in the rest position (FIG. 7), it can be housed in an insert housing 33, of longitudinal shape, formed from two housings formed in each of the half-shells of the key case 1. This insert housing, once the two half-shells assembled, is partially covered by the outer wall 34 of the key housing 1. Figure 8 presents, more particularly, the key 3 in the rest position, housed in a part of the housing insert 33 formed in the half-shell lower 36 of the key case 1.

La demi-coque inférieure 36 comporte un logement 32 pour l'électronique de communication 39 qui comprend, par exemple, un transpondeur et/ou une télécommande, ou encore une électronique de communication radiofréquence du type mains-libres, et qui est pourvue de moyens accumulateurs d'énergie 40. Dans le cas présent, le logement 32 pour l'électronique est séparé de façon hermétique du logement de la clé de secours par la présence de moyens d'étanchéité, par exemple un joint d'étanchéité.The lower half-shell 36 comprises a housing 32 for the communication electronics 39 which comprises, for example, a transponder and / or a remote control, or a radio-frequency communication electronics of the hands-free type, and which is provided with means energy accumulator 40. In this case, the housing 32 for the electronics is hermetically separated from the housing of the emergency key by the presence of sealing means, for example a seal.

Par ailleurs, pour faciliter la réalisation du mouvement de translation de la tête de clé 5 par rapport à l'insert 7 ou encore le retrait de la clé 3 de son logement d'insert 33, la tête de clé 5 présente sur son extrémité opposée à l'articulation 10 une encoche de préhension 30 pour les doigts de l'utilisateur (figure 6).Furthermore, to facilitate the realization of the translational movement of the key head 5 relative to the insert 7 or the removal of the key 3 from its insert housing 33, the key head 5 has on its opposite end. at the articulation 10 a gripping notch 30 for the fingers of the user (Figure 6).

En cas de non-utilisation, la clé de secours 3 doit être repliée, dans sa position de repos, de façon que la tête de clé 5 et l'insert 7 soient sensiblement parallèles l'un par rapport à l'autre, et être fixée, de préférence, par des moyens d'encliquetage complémentaires portés d'une part par la tête de clé et d'autre part par le boîtier de clé, dans le boîtier 1. Des moyens d'encliquetage 22, portés par la tête de clé 5, sont représentés à la figure 7.In case of non-use, the emergency key 3 must be folded, in its rest position, so that the key head 5 and the insert 7 are substantially parallel to each other, and be preferably fixed by complementary snap-fastening means carried on the one hand by the key head and on the other hand by the key housing, in the casing 1. Snap-fastening means 22, carried by the locking head, key 5, are represented in FIG.

Ainsi, grâce à l'invention, on a réalisé un boîtier de clé particulièrement simple d'utilisation et permettant d'intégrer une clé de secours.Thus, thanks to the invention, a key box has been made particularly easy to use and to integrate a backup key.

On comprend également que le boîtier de clé selon l'invention permet avantageusement de réduire l'encombrement pour la partie mécanique et de loger une clé de secours, qui peut être parfaitement utilisable en cas de besoin lorsque qu'elle est agencée en position d'utilisation.It is also understood that the key box according to the invention advantageously reduces the space requirement for the mechanical part and houses a spare key, which can be perfectly usable when needed when it is arranged in a position of use.

De plus, grâce à l'invention, la clé de secours peut être montée ultérieurement sur le boîtier, ce qui présente un avantage industriel important lorsque les moyens de fabrication de l'électronique et de l'insert avec les verrous correspondants se trouvent à des endroits éloignés géographiquement.In addition, thanks to the invention, the emergency key can be mounted later on the housing, which has a significant industrial advantage when the manufacturing means of the electronics and the insert with the corresponding latches are at geographically distant places.
