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 , 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, for example, document is known EP 0 987 389 key housings comprising an electronic part for the identification by exchange of electromagnetic signals of a user of the vehicle and a mechanical part enclosing a spare key.

En outre, le document JP 2007 231604 A divulgue un boitier de clé de véhicule automobile comprenant un logement d'insert de forme longitudinale, destiné à recevoir un insert, et une tête de clé destinée à être fixée à l'insert et formant une clé. La tête de clé formant d'une part couvercle de fermeture du boitier de clé et d'autre part partie de préhension de la clé. Le boitier comporte des moyens d'enclipsage réversibles complémentaires portés d'une part par le boitier et d'autre part par la tête de clé. Le moyen d'enclipsage porté par le boitier est mobile en translation entre une position de repos et une position de libération, selon une direction sensiblement perpendiculaire à la position d'enclipsage de la tête de clé sur le boitier, et comporte un coulisseau comprenant deux rampes d'enclipsage dirigées dans la même direction et destinées à s'engager avec les moyens d'enclipsage complémentaires portés par la tête de la clé.In addition, the document JP 2007 231604 A discloses a motor vehicle key case comprising a longitudinally shaped insert housing for receiving an insert, and a key head for attachment to the insert and forming a key. The key head forming on the one hand closing lid of the key box and on the other hand gripping part of the key. The housing comprises complementary reversible clipping means carried on the one hand by the housing and on the other hand by the key head. The clipping means carried by the housing is movable in translation between a rest position and a release position, in a direction substantially perpendicular to the clipping position of the key head on the housing, and comprises a slide comprising two clipping ramps directed in the same direction and intended to engage with the complementary clipping means carried by the head of the 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 portion and a metal insert that can be used as 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.

Cependant, de tels boitiers sont soumis aux cahiers des charges des constructeurs automobiles qui imposent des conditions de résistances à la traction et aux chocs. Ainsi le maintien de la clé de secours dans le boitier de clé doit également répondre à ces conditions qu'un simple encliquetage ne peut remplir.However, such boxes are subject to the specifications of car manufacturers who impose tensile strength and impact conditions. Thus the maintenance of the emergency key in the key box must also meet these conditions that a simple snap can not fill.

Ainsi un des buts de l'invention est de fournir un boitier de clé amélioré et permettant un maintien de la clé de secours optimal.Thus one of the aims of the invention is to provide an improved key box and allowing maintenance of the optimal backup key.

La présente invention concerne donc un boitier de clé, notamment de véhicule automobile, comprenant :

  • un boitier comprenant un logement d'insert de forme longitudinale, destiné à recevoir un insert, et
  • une tête de clé destinée à être fixée à l'insert et formant une clé, ladite tête de clé formant d'une part couvercle de fermeture du boitier de clé et d'autre part partie de préhension de la clé,
  • ledit boitier de clé comportant des moyens d'enclipsage réversibles complémentaires portés d'une part par le boitier et d'autre part par la tête de clé, au moins un des moyens d'enclipsage étant mobile en translation entre une position de repos et une position de libération, selon une direction sensiblement perpendiculaire à la position d'enclipsage de la tête de clé sur le boitier,
  • la tête de clé comporte deux moyens d'enclipsage, chaque moyen d'enclipsage étant positionné à une des extrémités de ladite tête de clé, un premier moyen d'enclipsage comportant une première encoche positionnée sur un étrier à une extrémité de la tête de clé, un second moyen d'enclipsage comportant une seconde encoche positionnée dans une base de la tête de clé, destinée à recevoir l'insert,
  • les moyens d'enclipsage complémentaires mobiles placés sur le boîtier, comportent un coulisseau comprenant deux rampes d'enclipsage dirigées dans la même direction et destinées à s'insérer dans lesdites encoches. Selon un autre aspect de l'invention, le coulisseau est en métal.
The present invention thus relates to a key box, especially a motor vehicle, comprising:
  • a housing comprising a longitudinally-shaped insert housing for receiving an insert, and
  • a key head intended to be fixed to the insert and forming a key, said key head forming, on the one hand, the closure lid of the key box and, on the other hand, the key gripping portion,
  • said key box comprising complementary reversible clipping means carried on the one hand by the housing and on the other hand by the key head, at least one of the clipping means being movable in translation between a rest position and a release position, in a direction substantially perpendicular to the clipping position of the key head on the housing,
  • the key head comprises two clipping means, each clipping means being positioned at one end of said key head, a first clipping means having a first notch positioned on a stirrup at one end of the key head a second clipping means having a second notch positioned in a base of the key head for receiving the insert,
  • the mobile complementary clipping means placed on the housing, comprise a slide comprising two clipping ramps directed in the same direction and intended to be inserted in said notches. According to another aspect of the invention, the slider is made of metal.

Selon un autre aspect de l'invention, le coulisseau comporte en outre un moyen élastique de retour en position de repos.According to another aspect of the invention, the slider further comprises an elastic return means in the rest position.

Selon un autre aspect de l'invention, le moyen élastique de maintien est un ressort.According to another aspect of the invention, the elastic holding means is a spring.

Selon un autre aspect de l'invention, les moyens d'enclipsage comprenant les encoches comportent un premier plan incliné et les rampes d'enclipsage comportent un second plan incliné, de sorte que lors du positionnement de la tête de clé sur le boitier, le premier plan incliné de chaque moyen d'enclipsage comprenant les encoches appuie sur le second plan incliné de chaque rampe d'enclipsage, entrainant le déplacement en position de libération du coulisseau.According to another aspect of the invention, the clipping means comprising the notches comprise a first inclined plane and the clipping ramps comprise a second inclined plane, so that when positioning the key head on the housing, the first inclined plane of each clipping means comprising the notches presses on the second inclined plane of each clipping ramp, causing the displacement in the release position of the slide.

Selon un autre aspect de l'invention, le coulisseau comporte un moyen de déverrouillage permettant son passage, sous l'action d'un utilisateur, de sa position de repos à sa position de libération.According to another aspect of the invention, the slide comprises an unlocking means allowing it to pass, under the action of a user, from its rest position to its release position.

Selon un autre aspect de l'invention, le moyen de déverrouillage est un bouton coulissant relié au coulisseau.According to another aspect of the invention, the unlocking means is a sliding button connected to the slider.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante, donnée à titre d'exemple illustratif et non limitatif, et des dessins annexés parmi lesquels :

  • la figure 1 montre une représentation schématique éclatée en perspective d'un boitier de clé et de sa clé de secours,
  • la figure 2 montre une représentation schématique en perspective d'un boitier de clé et de sa clé de secours détachée dudit boitier,
  • la figure 3 montre une représentation schématique en perspective d'un boitier de clé et de sa clé de secours attachée audit boitier.
Other features and advantages of the invention will emerge more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings among which:
  • the figure 1 shows an exploded schematic representation in perspective of a key box and its emergency key,
  • the figure 2 shows a schematic representation in perspective of a key case and its spare key detached from said case,
  • the figure 3 shows a schematic representation in perspective of a key box and its emergency key attached to said case.

Les éléments identiques sur les différentes figures portent les mêmes numéros de références.The identical elements in the different figures bear the same reference numbers.

La figure 1 montre une représentation schématique éclatée en perspective d'un boitier de clé, ledit boitier de clé comporte notamment une clé 1 de secours et un boitier 7.The figure 1 shows an exploded schematic representation in perspective of a key case, said key case including a spare key 1 and a case 7.

La clé 1 de secours comporte, fixés l'un à l'autre, une tête de clé 3 formant partie de préhension et un insert 5 destiné à être inséré dans un verrou, notamment de secours, d'un véhicule en cas d'utilisation.The emergency key 1 comprises, fixed to one another, a key head 3 forming a gripping portion and an insert 5 intended to be inserted into a lock, including a spare, a vehicle when used .

Le boitier 7 comprend notamment un logement d'insert 9 de forme longitudinale, destiné à recevoir l'insert 5 en cas de non-utilisation de la clé 1. Le boitier 7 peut comporter deux demi-coques 7A ; 7B. La première demi-coque 7A, pouvant par exemple recevoir les équipements électroniques, et la seconde demi-coque de recouvrement 7B, pouvant par exemple comporter des boutons de commandes telles que l'ouverture et la fermeture électrique des portes du véhicule automobile.The housing 7 comprises in particular an insert housing 9 of longitudinal shape, intended to receive the insert 5 in case of non-use of the key 1. The housing 7 may comprise two half-shells 7A; 7B. The first half-shell 7A, which can example to receive the electronic equipment, and the second half cover shell 7B, for example may include control buttons such as opening and closing the doors of the motor vehicle.

Le boitier de clé comprend en outre des moyens d'enclipsage réversibles et complémentaires, portés d'une part par le boitier 7 et d'autre part par la tête de clé 3, afin que cette dernière reste fixée contre le boitier 7 lorsqu'il n'est pas nécessaire de l'utiliser.The key box further comprises reversible and complementary clipping means, carried on the one hand by the housing 7 and on the other hand by the key head 3, so that the latter remains fixed against the housing 7 when it is not necessary to use it.

Afin d'assurer la fixation de la tête de clé 3 sur le boitier 7 et que ladite tête de clé 3 puisse se libérer du boitier 7, au moins un des moyens d'enclipsage est mobile en translation entre une position de repos et une position de libération, selon une direction sensiblement perpendiculaire à la position d'enclipsage de la tête de clé 3 sur le boitier 7. En position de libération, le ou les moyens d'enclipsage mobiles ne sont pas en relation avec son ou ses moyens d'enclipsage complémentaires, ce qui induit que la tête de clé 3 n'est plus fixée au boitier 7 et qu'il est donc possible de la retirer. A l'inverse, en position de repos, si la tête de clé 3 est positionnée sur le boitier 7, le ou les moyens d'enclipsage mobiles sont en relation avec son ou ses moyens d'enclipsage complémentaires, ce qui induit que la tête de clé 3 est fixée au boitier 7.To ensure the fixing of the key head 3 on the housing 7 and said key head 3 can be released from the housing 7, at least one of the clipping means is movable in translation between a rest position and a position release, in a direction substantially perpendicular to the clipping position of the key head 3 on the housing 7. In the release position, or the movable clipping means are not related to his or her means of complementary clipping, which induces that the key head 3 is no longer attached to the housing 7 and it is possible to remove it. Conversely, in the rest position, if the key head 3 is positioned on the housing 7, the movable engagement means or clocks are in relation with its complementary clipping means or means, which induces that the head key 3 is fixed to the casing 7.

Comme le montrent les figures 2 et 3, la tête de clé 3 peut comporter deux moyens d'enclipsage 13A, 13B. Dans un mode de réalisation avantageux mains non limitatif, les deux moyens d'enclipsage sont chacun positionnés à une extrémité de ladite tête de clé 3. Un premier moyen d'enclipsage peut comporter une première encoche 13A, par exemple positionnée sur un étrier 14 à une extrémité de la tête de clé 3. Un second moyen d'enclipsage peut également être une seconde encoche 13B, par exemple positionnée dans une base 12 de la tête de clé 3, destinée à recevoir l'insert 5.As shown by Figures 2 and 3 , the key head 3 may comprise two clipping means 13A, 13B. In an advantageous non-limiting embodiment, the two clipping means are each positioned at one end of said key head 3. A first clipping means may comprise a first notch 13A, for example positioned on a stirrup 14 to one end of the key head 3. A second clipping means may also be a second notch 13B, for example positioned in a base 12 of the key head 3, intended to receive the insert 5.

Complémentairement aux deux moyens d'enclipsage 13A, 13B de la tête de clé 3, le boitier 7 comporte également deux moyens d'enclipsage 15A, 15B mobiles. Ces deux moyens d'enclipsage 15A, 15B peuvent être des rampes d'enclipsage 15A, 15B dirigées dans la même direction et portées par un coulisseau 11. En position de repos et lorsque la tête de clé 3 est positionnée sur le boitier 7, les rampes d'enclipsage 15A, 15B sont insérées dans les encoches 13A, 13B, fixant ladite tête de clé 3 sur le boitier 7.Complementarily to the two clipping means 13A, 13B of the key head 3, the housing 7 also comprises two movable clipping means 15A, 15B. These two clipping means 15A, 15B may be snap ramps 15A, 15B directed in the same direction and carried by a slider 11. In the rest position and when the key head 3 is positioned on the housing 7, the clipping ramps 15A, 15B are inserted in the notches 13A, 13B, fixing said head of key 3 on the case 7.

Le coulisseau 11, par exemple réalisé en métal, peut comporter une barre longitudinale 111 à partir de laquelle s'étend, à chacune de ses extrémités et perpendiculairement à ladite barre longitudinale 111, une extension 113A et 113B, chacune portant une rampe d'enclipsage 15A, 15B. Le coulisseau 11 peut également comporter, entre les extensions 113A et 113B une troisième extension 115 s'étendant perpendiculairement à la barre longitudinale 111.The slider 11, for example made of metal, may comprise a longitudinal bar 111 from which extends, at each of its ends and perpendicularly to said longitudinal bar 111, an extension 113A and 113B, each carrying an engagement ramp 15A, 15B. The slider 11 may also comprise, between the extensions 113A and 113B, a third extension 115 extending perpendicularly to the longitudinal bar 111.

Le fait d'avoir au moins deux points de fixations de la tête de clé 3 sur le boitier 7, permet une fixation plus solide et résistante aux chocs ainsi qu'aux efforts de tractions susceptibles d'être appliqués à la tête de clé 3. De plus, le fait que les points de fixations soient situés aux extrémités de la tête de clé 3 permet un positionnement de ladite tête de clé 3 sur le boitier 7 amélioré, les porte-à-faux étant évités.The fact of having at least two attachment points of the key head 3 on the housing 7, allows a stronger and resistant to shock and traction efforts that can be applied to the key head 3. In addition, the fact that the attachment points are located at the ends of the key head 3 allows positioning of said key head 3 on the improved housing 7, the cantilevers being avoided.

Bien entendu, il est possible d'imaginer une configuration différente de celle présentée dans la description et sur les figures, par exemple où les encoches 13A, 13B sont situées sur le boitier électronique 7 et où le coulisseau 11 est situé sur la tête de clé 3.Of course, it is possible to imagine a configuration different from that presented in the description and in the figures, for example where the notches 13A, 13B are located on the electronic box 7 and where the slider 11 is located on the key head 3.

Comme le montre la figure 1, le coulisseau 11 peut être en contact avec une des deux demi-coques 7A, 7B du boitier 7 par sa troisième extension 115 et au moins une des extensions 113A et 113B.As shown in figure 1 , the slider 11 may be in contact with one of the two half-shells 7A, 7B of the housing 7 by its third extension 115 and at least one of the extensions 113A and 113B.

Le coulisseau 11 est alors placé dans un guide 19, situé sur au moins une des deux demi-coques 7A, 7B. Le guide 19 permet le maintien du coulisseau 11 et limite également ses mouvements lors du passage de sa position de repos à sa position de libération. Plus précisément, les mouvements autorisés sont des mouvements de translations perpendiculaires à l'axe d'introduction et de retrait de la tête de clé 3 dans le boitier 7.The slide 11 is then placed in a guide 19, located on at least one of the two half-shells 7A, 7B. The guide 19 keeps the slider 11 and also limits its movements during the transition from its rest position to its release position. More specifically, authorized movements are movements of translations perpendicular to the axis of introduction and withdrawal of the key head 3 in the housing 7.

Le guide 19 peut être situé sur une seule des demi-coques 7A, 7B ou bien être présent sur les deux demi-coques 7A, 7B à la fois. Ledit guide 19 peut ainsi comporter deux éléments de guidage parallèles, entre lesquels le coulisseau 11 est positionné et entre lesquels ledit coulisseau 11 peut passer de sa position de repos à sa position de libération par un mouvement de translation. Ces éléments de guidages peuvent être une paroi ou une série de plots alignés formant élément de guidage et sur lesquels s'appui et translate le coulisseau 11.The guide 19 may be located on only one of the half-shells 7A, 7B or be present on the two half-shells 7A, 7B at a time. Said guide 19 may thus comprise two parallel guide elements, between which the slider 11 is positioned and between which said slider 11 can move from its rest position to its release position by a translational movement. These guide elements may be a wall or a series of aligned pins forming a guide element and on which supports and translates the slide 11.

Le coulisseau 11 peut également comporter un moyen élastique 17 permettant par défaut le retour dudit coulisseau 11 à sa position de repos. Ce moyen élastique 17 peut être par exemple un ressort placé entre une butée présente sur le boitier 7 et une des extensions 113A, 113B, 115 du coulisseau 11.The slider 11 may also comprise an elastic means 17 allowing by default the return of said slider 11 to its rest position. This elastic means 17 may be for example a spring placed between an abutment on the housing 7 and one of the extensions 113A, 113B, 115 of the slider 11.

Les moyens d'enclipsage comprenant les encoches 13A, 13B peuvent également comporter un premier plan incliné 21A et les rampes d'enclipsage 15A, 15B peuvent comporter complémentairement un second plan incliné 21B. Lors du positionnement de la tête de clé 3 dans le boitier 7 et d'une poussée d'un utilisateur, le premier plan incliné 21A de chaque moyen d'enclipsage comprenant les encoches 13A, 13B appuie sur le second plan incliné 21B des rampes d'enclipsage 15A, 15B, de sorte à entrainer le déplacement en translation du coulisseau 11 vers sa position de libération. Une fois les rampes d'enclipsage 15A, 15B en face des encoches 13A, 13B, les premiers plans inclinés 21A et les seconds plans inclinés 21B ne sont plus en contacts, et le moyen élastique 17 ramène le coulisseau 11 vers sa position de repos, les rampes d'enclipsage 15A, 15B s'insérant ainsi dans les encoches 13A, 13B.The clipping means comprising the notches 13A, 13B may also comprise a first inclined plane 21A and the clipping ramps 15A, 15B may additionally comprise a second inclined plane 21B. When positioning the key head 3 in the housing 7 and a thrust of a user, the first inclined plane 21A of each clipping means comprising the notches 13A, 13B presses on the second inclined plane 21B of the ramps clipping 15A, 15B, so as to cause the translational movement of the slide 11 to its release position. Once the clipping ramps 15A, 15B face the notches 13A, 13B, the first inclined planes 21A and the second inclined planes 21B are no longer in contact, and the elastic means 17 returns the slide 11 to its rest position, the clipping ramps 15A, 15B thus fitting into the notches 13A, 13B.

Le coulisseau peut en outre comporter un moyen de déverrouillage 27, permettant à un utilisateur le faire passer de sa position de repos à sa position de libération, afin de retirer la tête de clé 3 du boitier 7. Comme le montre la figure 1, le moyen de déverrouillage 27 peut être un bouton coulissant, relié au coulisseau 11 au niveau d'une de ses extensions 113A, 113B, 115, et manipulable au travers d'une ouverture (non représentée) pratiquée dans une des demi-coques 7A, 7B.The slider may further comprise an unlocking means 27, allowing a user to move it from its rest position to its release position, in order to remove the key head 3 from the housing 7. As shown in figure 1 , the unlocking means 27 may be a sliding button, connected to the slider 11 at one of its extensions 113A, 113B, 115, and manipulable through an opening (not shown) formed in one of the half-shells 7A , 7B.

Ainsi, on voit bien que le boitier de clé selon l'invention, du fait de ses moyens d'enclisages, permet un maintien optimal et résistant aux chocs de la clé 1 de secours au niveau du boitier 7, permettant ainsi de remplir les conditions définies par les constructeurs dans leur cahier des chargesThus, it is clear that the key box according to the invention, because of its locking means, allows an optimal and resistant to shock of the emergency key 1 at the housing 7, thus fulfilling the conditions defined by the manufacturers in their specifications
