Description

L'invention propose une clé de véhicule automobile.The invention provides a motor vehicle key.

L'invention propose plus particulièrement une clé, du type comportant une tige s'étendant selon une direction horizontale sensiblement longitudinale, et un boítier formant tête de manoeuvre de la clé qui comporte un logement longitudinal formant mortaise qui est ouvert longitudinalement vers l'avant et dans lequel est reçu un talon arrière de la tige formant tenon, du type comportant des moyens de verrouillage longitudinal du talon en position dans le logement qui sont aptes à se déformer élastiquement lors de l'insertion du talon dans le logement, et qui sont aptes à reprendre leur état de repos.The invention more particularly provides a key, of the type having a rod extending in a horizontal direction substantially longitudinal, and a housing forming a head operation of the key which comprises a longitudinal housing forming a mortise which is open longitudinally forward and in which is received a rear heel of the post-forming rod, type comprising means for longitudinal locking of the heel in position in the housing which are able to deform elastically when the heel is inserted into the housing, and which are able to return to their resting state.

Les clés de contact des véhicules automobiles actuels comportent, en plus de leur tige permettant de manoeuvrer manuellement une serrure, un émetteur électronique qui est contenu dans un boítier formant la tête de manoeuvre de la clé pour la commande à distance de certaines fonctions comme le verrouillage des portes ou la mise en route de l'alarme.The ignition keys of current motor vehicles have, in addition to their rod for maneuvering manually a lock, an electronic transmitter which is contained in a housing forming the operating head of the key for remote control of certain functions such as the locking the doors or activating the alarm.

Etant donné que les compétences requises pour réaliser la partie électronique diffèrent de celles requises pour la réalisation de la partie mécanique, le boítier et la tige sont parfois fabriqués indépendamment l'un de l'autre par deux fabricants différents. La clé est ensuite assemblée lors du montage du véhicule chez le constructeur de sorte que le récepteur associé à l'émetteur et la serrure associée à la tige soient montés sur le même véhicule.Since the skills required to perform the electronic part differ from those required for the realization of the mechanical part, the housing and the rod are sometimes manufactured independently of each other by two different manufacturers. The key is then assembled when mounting the vehicle at the constructor so the receiver associated with the transmitter and the lock associated with the rod are mounted on the same vehicle.

L'assemblage de certaines clés connues nécessite de démonter en partie le boítier pour pouvoir introduire une partie de la tige dans un logement complémentaire du boítier.The assembly of certain known keys requires partially disassemble the housing to be able to introduce part of the rod in a complementary housing of the housing.

On comprend aisément que de telles manipulations peuvent s'avérer relativement coûteuses, notamment car elles nécessitent un certain temps de montage.It is easy to understand that such manipulations can be relatively expensive, especially since they require some assembly time.

Il a été proposé dans le document EP-A-0.582.513 d'introduire le talon arrière de la tige dans une ouverture de la face avant du boítier. Le verrouillage en position de la tige est réalisé par un bossage de la coque inférieure du boítier qui est reçu dans une ouverture complémentaire du talon de la tige.It was proposed in document EP-A-0.582.513 introduce the rear heel of the upper into an opening in the front face of the case. The locking in position of the rod is produced by a boss of the lower shell of the housing which is received in a complementary opening in the heel of the upper.

Lors de l'insertion de la tige, la coque inférieure se déforme pour que le bossage s'efface, permettant ainsi le passage du talon.When inserting the rod, the lower shell deforms so that the boss disappears, allowing the passage of the heel.

La coque inférieure doit alors être conçue de sorte à comporter une zone déformable élastiquement qui est alors de résistance moindre et donc plus apte à la rupture.The lower shell must then be designed so that have an elastically deformable zone which is then lower resistance and therefore more apt to break.

Pour cela, l'invention propose une clé du type décrit précédemment, caractérisée en ce que les moyens de verrouillage comportent au moins une patte de verrouillage qui s'étend sensiblement longitudinalement vers l'arrière et qui est apte à s'escamoter dans un logement complémentaire du boítier lors de l'insertion longitudinale d'avant en arrière du talon dans le logement.For this, the invention provides a key of the type described previously, characterized in that the locking means have at least one locking tab which extends substantially longitudinally towards the rear and which is capable of retract into a complementary housing of the housing during longitudinal insertion from front to back of the heel in the housing.

Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence.In the description which follows, identical elements, similar or analogous will be designated by the same numbers reference.

On a représenté à la figure 1 une clé 10 qui permet de faire fonctionner le mécanisme d'une serrure (non représentée) d'un véhicule automobile qui comporte un boítier 12 et une tige 14 représentée sous forme schématique simplifiée.There is shown in Figure 1 a key 10 which allows operate the mechanism of a lock (not shown) of a motor vehicle which comprises a housing 12 and a rod 14 shown in simplified schematic form.

La clé 10 comporte aussi un dispositif électronique 16 qui est fixé à l'intérieur du boítier 12.The key 10 also includes an electronic device 16 which is fixed inside the housing 12.

Ce dispositif électronique 16 permet notamment de commander à distance le verrouillage et le déverrouillage des portières. Pour cela, il comporte des boutons de commande 18 de ses différentes fonctions qui s'étendent verticalement à travers la paroi supérieure du boítier 12.This electronic device 16 makes it possible in particular to remotely control the locking and unlocking of doors. For this, it includes control buttons 18 of its different functions which extend vertically across the upper wall of the housing 12.

Le boítier 12 forme la tête de la clé 10 et il permet de manoeuvrer la clé 10, notamment pour la faire pivoter dans la serrure autour de l'axe longitudinal de la tige 14. Il comporte une coque inférieure 20 qui est ouverte à sa face supérieure 22 pour permettre l'accès au dispositif électronique 16. Le boítier comporte aussi une coque supérieure 24 pour la fermeture de la face supérieure 22 de la coque inférieure 20.The case 12 forms the head of the key 10 and it allows operate the key 10, in particular to rotate it in the lock around the longitudinal axis of the rod 14. It has a lower shell 20 which is open at its upper face 22 for allow access to the electronic device 16. The housing also includes an upper shell 24 for closing the upper face 22 of the lower shell 20.

La tige 14 est fixée au boítier 12 par un assemblage du type tenon mortaise. Pour cela, la coque inférieure 20 comporte un logement 26 longitudinal ouvert longitudinalement vers l'avant et délimité par deux parois longitudinales verticales et opposées 38 et deux parois longitudinales horizontales opposées supérieure 40s et inférieure 40i, dans lequel est reçu un talon arrière 28 de la tige 14 de forme complémentaire. De plus, le logement 26 comporte une face d'extrémité arrière 41 contre laquelle l'extrémité longitudinale arrière du talon 28 vient en butée arrière. The rod 14 is fixed to the housing 12 by an assembly of the mortise tenon type. For this, the lower shell 20 has a longitudinal housing 26 open longitudinally forward and delimited by two vertical and opposite longitudinal walls 38 and two opposite horizontal longitudinal walls upper 40s and lower 40i, in which a rear heel 28 of the rod 14 of complementary shape. In addition, the accommodation 26 has a rear end face 41 against which the rear longitudinal end of the heel 28 comes into abutment.

Pour permettre l'entraínement en rotation de la tige 14, le logement 26 et le talon 28 sont de section transversale sensiblement rectangulaire.To allow the rotary drive of the rod 14, the housing 26 and the heel 28 are of cross section substantially rectangular.

La clé comporte une cheville 30 pour le verrouillage longitudinal du talon 28 de la tige 14 dans le logement 26.The key has a dowel 30 for locking longitudinal of the heel 28 of the rod 14 in the housing 26.

Comme on l'a représenté aux figures 4 et 5, la cheville 30 est une pièce en forme de U dont les deux branches parallèles 32 s'étendent verticalement vers le bas depuis la branche horizontale supérieure 34 du U. La cheville 30 chevauche le talon 28, et chaque branche 32 est reçue dans une gorge latérale 39 d'une paroi latérale 38 du logement 26.As shown in Figures 4 and 5, the pin 30 is a U-shaped piece with two parallel branches 32 extend vertically downward from the horizontal branch upper 34 of the U. The ankle 30 overlaps the heel 28, and each branch 32 is received in a lateral groove 39 of a side wall 38 of the housing 26.

Ainsi, puisque les branches verticales 32 de la cheville 30 sont reçues dans les gorges 39, la cheville 30 ne peut se déplacer longitudinalement.So, since the vertical branches 32 of the ankle 30 are received in the grooves 39, the ankle 30 cannot move longitudinally.

Pour sa mise en place, la cheville 30 est introduite verticalement vers le bas en traversant la paroi supérieure 40s délimitant le logement 26. A cet effet, la paroi supérieure 40s comporte une ouverture supérieure 42, représentée à la figure 2.For its installation, the dowel 30 is introduced vertically downward through the top wall 40s delimiting the housing 26. For this purpose, the upper wall 40s has an upper opening 42, shown in FIG. 2.

Cette ouverture 42 est de section horizontale complémentaire à la branche supérieure 34 du U de sorte à former une cavité complémentaire de la branche supérieure 34.This opening 42 is of horizontal section complementary to the upper branch 34 of the U so that form a complementary cavity of the upper branch 34.

Lorsque la coque supérieure 24 du boítier 12 est en position montée, c'est à dire lorsqu'elle ferme la face supérieure 22 de la coque inférieure 20, elle recouvre par la même occasion l'ouverture supérieure 42 de la paroi supérieure 40s.When the upper shell 24 of the housing 12 is in mounted position, i.e. when it closes the upper side 22 of the lower shell 20, it covers at the same time the upper opening 42 of the upper wall 40s.

Conformément aux enseignements de l'invention, la cheville 30 comporte des pattes de verrouillage 44 qui s'étendent chacune sensiblement horizontalement vers l'arrière, depuis une branche verticale 32 de la cheville 30. Chaque patte 44 est recourbée transversalement vers l'intérieur de la cheville 30 de sorte que leur extrémité longitudinale arrière libre 54 s'appuie contre la face transversale verticale 27 de la gorge 36 associée pour le verrouillage en position du talon 28. In accordance with the teachings of the invention, the dowel 30 has locking tabs 44 which extend each substantially horizontally backwards, from a vertical branch 32 of the ankle 30. Each tab 44 is bent transversely towards the inside of the ankle 30 of so that their free rear longitudinal end 54 is supported against the vertical transverse face 27 of the associated groove 36 for locking the heel in position 28.

Ainsi, l'extrémité longitudinale arrière 54 de chaque patte 44 s'appuie contre la face arrière 27 de la gorge 36 associée pour réaliser le verrouillage longitudinal du talon 28.Thus, the rear longitudinal end 54 of each leg 44 bears against the rear face 27 of the associated groove 36 for perform the longitudinal locking of the heel 28.

Les figures 1 à 3 représentent les étapes successives de l'assemblage de la tige 14 avec le boítier 20.Figures 1 to 3 show the successive stages of the assembly of the rod 14 with the housing 20.

Tout d'abord, comme représenté la figure 1, le boítier 12 est assemblé indépendamment de la fabrication de la tige 14. Lors de l'assemblage du boítier 12, la cheville 30 est introduite dans la coque inférieure 20 par l'ouverture 42.First, as shown in Figure 1, the housing 12 is assembled independently of the manufacture of the rod 14. During assembly of the housing 12, the dowel 30 is introduced in the lower shell 20 through the opening 42.

Ensuite, le talon 28 de la tige 14 est introduit à l'intérieur du logement 26 par la face avant 37 du logement 26 qui est ouverte.Then, the heel 28 of the rod 14 is introduced inside of the housing 26 by the front face 37 of the housing 26 which is opened.

Ensuite, le talon est inséré longitudinalement d'avant en arrière dans le logement.Then the heel is inserted longitudinally back and forth back in the housing.

Lors de l'insertion du talon 28, les pattes 44 se déforment élastiquement et s'escamotent à l'intérieur des gorges 39 pour permettre le passage du talon 28. Lorsque le talon est en position dans le logement 26, le pattes 44 reviennent élastiquement dans leur position initiale dans laquelle leur extrémités arrières 54 s'étendent respectivement à l'intérieur du logement 26 de sorte à s'appuyer contre les faces arrières 27 des gorges 36 du talon 28 pour assurer le verrouillage longitudinal du talon 28.When inserting the heel 28, the legs 44 deform elastically and retract inside the grooves 39 to allow passage of the heel 28. When the heel is in position in the housing 26, the lugs 44 return elastically in their initial position in which their rear ends 54 extend respectively inside the housing 26 so as to lean against the rear faces 27 of the grooves 36 of the heel 28 to ensure longitudinal locking of the heel 28.

Selon un mode de réalisation préféré de l'invention, les pattes 44 sont réalisées venues de matière avec la branche 32 de la cheville 30 associée, et elles sont réalisées par exemple par découpage puis par déformation d'une partie de la branche 32.According to a preferred embodiment of the invention, the legs 44 are made integrally with branch 32 of the associated pin 30, and they are produced for example by cutting then by deformation of a part of the branch 32.

Selon une variante de réalisation de l'invention représenté aux figures 6 à 8, la tige 14 est escamotable à l'intérieur du boítier 12. Ceci permet de protéger la tige 14 contre d'éventuelles agressions extérieures qui pourraient l'endommager, et ainsi empêcher le fonctionnement de la serrure. De plus, lorsque la tige 14 est en position escamotée, la clé 10 occupe un espace moins encombrant que lorsqu'elle est déployée à l'extérieur du boítier. According to an alternative embodiment of the invention shown in Figures 6 to 8, the rod 14 is retractable inside the case 12. This protects the rod 14 against possible external aggressions that could damage it, and so prevent the lock from working. In addition, when the stem 14 is in the retracted position, the key 10 occupies less space bulky only when it is deployed outside the case.

Pour cela, la clé 10 comporte un organe d'articulation 48 qui est monté articulé par rapport au boítier 12 autour d'un axe vertical A. L'organe d'articulation 48 comporte le logement 26 qui reçoit le talon 28 de la tige 14, et il est mobile en rotation entre une première position dans laquelle la tige 14 s'étend longitudinalement vers l'avant à l'extérieur du boítier 12, et une position repliée à 180° dans laquelle la tige 14 est entièrement escamotée dans le boítier 12.For this, the key 10 includes an articulation member 48 which is mounted articulated relative to the housing 12 about an axis vertical A. The articulation member 48 comprises the housing 26 which receives the heel 28 of the rod 14, and it is movable in rotation between a first position in which the rod 14 extends longitudinally forward outside the housing 12, and a 180 ° folded position in which the rod 14 is entirely retracted into the housing 12.

De plus, l'axe A de rotation de l'organe d'articulation 48 est décalé transversalement par rapport à l'axe longitudinal du logement 26 de sorte que lorsque la tige 14 est en position escamotée dans le boítier 12, elle est reçue dans un second logement 50 réalisé dans une extrémité transversale du boítier 12, ce qui permet de conserver une majeure partie du volume intérieur du boítier 12 qui reçoit le dispositif électronique 16.In addition, the axis A of rotation of the articulation member 48 is offset transversely to the longitudinal axis of the housing 26 so that when the rod 14 is in position retracted into the housing 12, it is received in a second housing 50 produced in a transverse end of the housing 12, which keeps most of the volume inside the housing 12 which receives the electronic device 16.

Il sera compris que les inversions mécaniques simples peuvent constituer des variantes de réalisation de l'invention. Par exemple, le logement 26 peut ne pas comporter de face arrière 41 de butée du talon 28, celui-ci venant en butée contre une face externe avant du boítier 12.It will be understood that simple mechanical inversions may constitute alternative embodiments of the invention. Through example, the housing 26 may not have a rear face 41 heel stop 28, the latter coming into abutment against one face external front of the housing 12.

L'utilisation des pattes 44 pour le verrouillage longitudinal du talon 28 dans le logement 26 permet un assemblage simple de la clé 10. De plus, le mode d'introduction du talon 28 étant selon une seule direction, cette opération est alors facilement automatisable, ce qui permet de réduire les coûts d'assemblage de la clé 10.Use of lugs 44 for longitudinal locking of the heel 28 in the housing 26 allows a simple assembly of the key 10. In addition, the method of introducing the heel 28 being according to only one direction, this operation is then easily can be automated, which reduces assembly costs of the key 10.
