Description

La présente invention concerne un ensemble de clé et boîtier utilisable par exemple pour l'actionnement des serrures de véhicules automobiles. De tels ensembles sont par exemple décrits par le document Brevet DE60016508 T2 .The present invention relates to a set of key and housing used for example for actuating locks of motor vehicles. Such sets are for example described by the patent document DE60016508 T2 .

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Il existe des clés comme celle du document brevet FR2 816 976 ayant une extrémité solidaire d'une chape montée dans un boîtier pour tourner autour d'un axe de pivotement entre une position escamotée de la clé dans le boîtier et une position sortie de la clé. Un poussoir de commande est monté dans un logement de la chape pour être solidaire en pivotement de celle-ci et pour coulisser entre une position de maintien de la chape dans la position escamotée et une position de libération du pivotement de la chape. Un ressort est intercalé entre le boîtier et le poussoir de commande pour rappeler élastiquement la chape dans sa position sortie et le poussoir de commande dans sa position de maintien.There are keys like the patent document FR2 816 976 having an end secured to a clevis mounted in a housing for rotation about a pivot axis between a retracted position of the key in the housing and an extended position of the key. A control pusher is mounted in a housing of the yoke to be integral in pivoting thereof and for sliding between a holding position of the yoke in the retracted position and a release position of the pivoting of the yoke. A spring is interposed between the housing and the control pusher to elastically return the yoke in its extended position and the control pusher in its holding position.

Le poussoir de commande sert de pivot pour la clé et transmet des efforts de torsion du boîtier vers la clé lorsque la clé est utilisée pour actionner une serrure. Le poussoir de commande doit être dimensionné pour supporter de tels efforts.The control pushbutton serves as a pivot for the key and transmits twisting forces from the housing to the key when the key is used to actuate a lock. The control pusher must be sized to withstand such efforts.

En outre, dans certaines clés, le poussoir de commande est pourvu d'ergots en saillie externe pour coopérer avec des rainures de la chape et des encoches du boîtier. Le poussoir a ainsi une structure relativement complexe et est réalisé en matériau thermoplastique injecté pour rester relativement peu coûteux à produire. Le matériau thermoplastique utilisé doit donc être adapté au mode de fabrication et présenter une résistance mécanique suffisante pour supporter les efforts mis en oeuvre lors de l'actionnement de la serrure. Un tel matériau s'avère relativement coûteux.In addition, in some keys, the control pusher is provided with lugs projecting externally to cooperate with grooves of the yoke and notches of the housing. The pusher thus has a relatively complex structure and is made of injected thermoplastic material to remain relatively inexpensive to produce. The thermoplastic material used must therefore be adapted to the method of manufacture and have sufficient mechanical strength to withstand the forces involved in operating the lock. Such a material proves relatively expensive.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Un but de l'invention est de fournir un ensemble avec une clé rétractable ayant un pivot de résistance améliorée tout en restant de coût modéré.An object of the invention is to provide an assembly with a retractable key having an improved resistance pivot while remaining moderate cost.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

A cet effet, on prévoit, selon l'invention, un ensemble selon la revendication 1.For this purpose, there is provided, according to the invention, an assembly according to claim 1.

Ainsi, la chape est maintenue dans le boîtier par le pivot dont les extrémités sont reçues dans les joues du boîtier. Les efforts exercés sur la clé par l'intermédiaire du boîtier sont repris par le pivot et non par le bouton de commande. Le pivot, qui n'a qu'une fonction de guidage en rotation et de reprise d'efforts, peut être en un matériau résistant et par exemple en métal, tandis que le poussoir de commande n'assure que sa fonction de maintien en position de la chape ou de libération du pivotement de celle-ci. En outre, cet agencement n'introduit que peu, ou pas, de modifications sur le boîtier de sorte que les boîtiers de l'art antérieur peuvent être utilisés sans adaptation majeure. On économise ainsi la réalisation d'un nouveau moule.Thus, the yoke is held in the housing by the pivot whose ends are received in the cheeks of the housing. The forces exerted on the key through the housing are taken over by the pivot and not by the control button. The pivot, which has only a function of guiding rotation and effort recovery, can be made of a resistant material and for example metal, while the control pushbutton ensures only its function of holding in position the clevis or release of the pivoting thereof. In addition, this arrangement introduces little or no changes to the housing so that the housings of the prior art can be used without major adaptation. This saves the creation of a new mold.

Avantageusement, les extrémités du pivot sont ouvertes et un ressort s'étend dans le pivot avec des extrémités solidaires du poussoir de commande et de la joue du boîtier opposée au poussoir de commande pour rappeler élastiquement la chape dans la position sortie et le poussoir de commande dans sa position de maintien.Advantageously, the ends of the pivot are open and a spring extends in the pivot with ends integral with the control pusher and the cheek of the housing opposite to the control pusher for resiliently returning the yoke in the extended position and the control pusher in its holding position.

Ce mode de réalisation est particulièrement simple et compact.This embodiment is particularly simple and compact.

De préférence, la rainure comporte un tronçon d'entrée débouchant par une première extrémité sur une face externe de la chape et débouchant par une deuxième extrémité dans un tronçon terminal en formant un angle avec celui-ci, le tronçon terminal s'étendant selon l'axe de pivotement.Preferably, the groove comprises an inlet section opening through a first end on an outer face of the yoke and opening through a second end in a terminal section at an angle thereto, the terminal section extending along 'axis pivoting.

Ainsi, le tronçon terminal accueille l'ergot du poussoir de commande en opération et permet son coulissement entre sa position de maintien et sa position de libération. Le tronçon d'entrée permet d'introduire l'ergot dans le tronçon terminal sans qu'il soit nécessaire de déformer le poussoir de commande, l'ergot ou la chape. Le montage est ainsi particulièrement simple et aisé et n'occasionne pas de sollicitations excessives des pièces.Thus, the terminal section receives the lug of the control pusher in operation and allows it to slide between its holding position and its release position. The input section makes it possible to introduce the lug into the terminal section without it being necessary to deform the control pusher, the lug or the yoke. The assembly is thus particularly simple and easy and does not cause excessive stresses parts.

D'autres caractéristiques et avantages ressortiront à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention définie par les revendications annexées.Other features and advantages will emerge on reading the following description of a particular non-limiting embodiment of the invention defined by the appended claims.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

L'ensemble conforme à l'invention est ici décrit en tant qu'un dispositif d'actionnement de serrures telles que celles d'un véhicule automobile. En particulier, l'ensemble est utilisable pour le verrouillage et le déverrouillage des ouvrants (portières, de la malle, ...) de l'interrupteur d'allumage et de la colonne de direction.The assembly according to the invention is here described as a device for actuating locks such as those of a motor vehicle. In particular, the assembly is used for locking and unlocking the opening (doors, trunk, ...) of the ignition switch and the steering column.

La clé, généralement désignée en 1, est montée dans un boîtier 2 pour pivoter entre une position escamotée dans un renfoncement latéral 3 du boîtier 2 et une position sortie dans laquelle la clé 1 s'étend à 180° par rapport à sa position escamotée. Le boîtier 2 est ici formé d'un réceptacle 4 fermé par un couvercle 5 et renferme ici un module électronique de télécommande agencé de manière connue en elle-même pour actionner à distance un dispositif centralisé de verrouillage et déverrouillage des ouvrants (les portières, la malle) du véhicule automobile.The key, generally designated 1, is mounted in a housing 2 for pivoting between a retracted position in a lateral recess 3 of the housing 2 and an extended position in which the key 1 extends 180 ° relative to its retracted position. The housing 2 is here formed of a receptacle 4 closed by a cover 5 and here encloses an electronic remote control module arranged in a manner known per se for remotely actuating a centralized locking and unlocking device for the doors (the doors, the trunk) of the motor vehicle.

La clé 1 comprend une extrémité 6 fixée dans une chape généralement désignée en 7 et montée dans une extrémité du renfoncement latéral 3 entre des joues 20 du boîtier 2 pour pivoter entre la position sortie et la position escamotée de la clé 1.The key 1 comprises an end 6 fixed in a clevis generally designated 7 and mounted in one end of the lateral recess 3 between the cheeks 20 of the housing 2 to pivot between the extended position and the retracted position of the key 1.

La chape 7 possède deux faces externes 8, 9 parallèles et opposées l'une à l'autre. La chape 7 comporte un logement 10 ayant un axe central 11 perpendiculaire à la direction longitudinale de la clé 1 et aux faces externes 8, 9. Le logement 10 présente une section transversale circulaire et débouche sur les faces externes 8, 9.The yoke 7 has two external faces 8, 9 parallel and opposite to each other. The yoke 7 comprises a housing 10 having a central axis 11 perpendicular to the longitudinal direction of the key 1 and the outer faces 8, 9. The housing 10 has a circular cross section and opens on the outer faces 8, 9.

Des rainures 12 sont ménagées dans le logement 10. Les rainures 12 sont décalées angulairement l'une par rapport à l'autre d'un angle α valant ici 170° environ. Ce décalage angulaire inférieure à 180° permet d'éviter qu'une des rainures n'empiète sur la zone de la chape 7 dévolue à l'extrémité 6 de la clé 1 tout en ayant une chape 7 relativement compacte.Grooves 12 are formed in the housing 10. The grooves 12 are angularly offset relative to each other by an angle α which is approximately 170 °. This angular offset less than 180 ° prevents one of the grooves impinge on the area of the clevis 7 devolving at the end 6 of the key 1 while having a relatively compact clevis 7.

Chaque rainure 12 comprend un tronçon d'entrée 13 débouchant par une portion d'extrémité 13.1 sur la face externe 8 de la chape 7 et par une portion d'extrémité 13.2 dans un tronçon terminal 14 ici borgne.Each groove 12 comprises an inlet section 13 opening through an end portion 13.1 on the outer face 8 of the yoke 7 and an end portion 13.2 in a terminal section 14 here blind.

Le tronçon d'entrée 13 a ici une forme en L, c'est-à-dire que la portion d'extrémité 13.1 s'étend parallèlement à l'axe central 11 et la portion d'extrémité 13.2 s'étend selon une circonférence du logement 10. La portion d'extrémité 13.2 n'est ici délimité latéralement que par un flanc situé du côté de la face externe 8, pour simplifier la fabrication de la chape 7 (ceci sera explicité plus loin).The inlet section 13 here has an L shape, that is to say that the end portion 13.1 extends parallel to the central axis 11 and the end portion 13.2 extends along a circumference of the housing 10. The end portion 13.2 is here delimited laterally only by a sidewall on the side of the outer face 8, to simplify the manufacture of the yoke 7 (this will be explained later).

Le tronçon terminal 14 s'étend parallèlement à l'axe central 11 et est situé derrière la portion d'extrémité 13.1 par référence au sens de pivotement de la clé 1 de sa position escamoté vers sa position sortie. Le tronçon terminal 14 possède du côté opposé à la portion d'extrémité 13.2 un flanc 28 qui s'étend axialement dans le logement 10.The end section 14 extends parallel to the central axis 11 and is located behind the end portion 13.1 with reference to the pivoting direction of the key 1 from its retracted position to its extended position. The end section 14 has on the side opposite to the end portion 13.2 a flank 28 which extends axially in the housing 10.

Le logement 10 de la chape 7 accueille un pivot généralement désigné en 16 et un poussoir de commande généralement désigné en 17 entre lesquels s'étend un ressort 18 (le ressort 18 est visible sur la figure 1 mais n'a pas été représenté sur la figure 6 pour ne pas surcharger cette figure).The housing 10 of the yoke 7 accommodates a pivot generally designated 16 and a control pusher generally designated 17 between which extends a spring 18 (the spring 18 is visible on the figure 1 but was not represented on the figure 6 not to overload this figure).

Le pivot 16 a une forme extérieure cylindrique à contour circulaire et possède des extrémités 19, 21 ouvertes reçues à pivotement dans des logements des joues 20 du boîtier 2. Le pivot 16 définit un axe d'articulation et de pivotement de la chape 7 par rapport au boîtier 2. Cet axe d'articulation et de pivotement est confondu avec l'axe central 11. Le pivot 16 est ici en métal.The pivot 16 has a cylindrical outer shape with a circular contour and has ends 19, 21 open pivotally received in housings 20 of the flanges 20 of the housing 2. The pivot 16 defines an axis of articulation and pivoting of the yoke 7 relative to to the housing 2. This axis of articulation and pivoting coincides with the central axis 11. The pivot 16 is here made of metal.

Le poussoir de commande 17 a une surface extérieure cylindrique circulaire et possède une extrémité pourvue de portions terminales 22 qui s'étendent en saillie axiale et sont reçues dans le logement 10 et une extrémité 23 opposée dont une portion s'étend en saillie du logement 10 et du couvercle 5 en passant par une lumière de ce dernier.The control pusher 17 has a circular cylindrical outer surface and has an end provided with end portions 22 which extend in axial projection and are received in the housing 10 and an opposite end 23, a portion of which projects from the housing 10. and the lid 5 through a light of the latter.

Les portions terminales 22 sont reçues à coulissement parallèlement à l'axe central 11 dans des encoches 30 ménagées dans l'extrémité 19 du pivot 16. Les encoches 30 ont une largeur ajustée à la largeur des portions 22 pour limiter au minimum le jeu angulaire entre le pivot 16 et le poussoir de commande 17. Les flancs des encoches 30 et des portions 22 sont parallèles à la direction de coulissement du poussoir de commande 17 (c'est-à-dire parallèle à l'axe central 11). Le poussoir de commande 17 et le pivot 16 sont ainsi liés en rotation. Les portions terminales 22 sont pourvues chacune d'un ergot 24. Les deux ergots 24 sont décalés angulairement l'un par rapport à l'autre de 170° et sont reçus dans les tronçons terminaux 14 des rainures 12 pour coulisser entre une position de blocage du pivotement de la chape 7 et une position de libération du pivotement de la chape 7. Dans la position de blocage, deux ergots 25 s'étendant en saillie radiale de l'extrémité 23 en retrait de la face terminale de celle-ci sont engagés dans deux encoches 26 ménagées au voisinage de la lumière du couvercle 5 du boîtier 2 à 180° l'une de l'autre. Dans la position de libération du pivotement de la chape 7, le poussoir de commande 17 est enfoncé et les ergots 25 sont dégagés des encoches 26.The end portions 22 are slidably received parallel to the central axis 11 in notches 30 in the end 19 of the pivot 16. The notches 30 have a width adjusted to the width of the portions 22 to minimize the angular play between the pivot 16 and the control pusher 17. The sides of the notches 30 and portions 22 are parallel to the direction of sliding of the control pushbutton 17 (that is to say parallel to the central axis 11). The control pusher 17 and the pivot 16 are thus connected in rotation. The end portions 22 are each provided with a lug 24. The two lugs 24 are offset angularly relative to each other by 170 ° and are received in the end sections 14 of the grooves 12 to slide between a locking position of the pivoting of the yoke 7 and a position of release of the pivoting of the yoke 7. In the locking position, two lugs 25 projecting radially from the end 23 set back from the end face thereof are engaged in two notches 26 formed in the vicinity of the light of the cover 5 of the housing 2 180 ° from one another. In the position of release of the pivoting of the yoke 7, the control pusher 17 is depressed and the lugs 25 are disengaged from the notches 26.

Le poussoir de commande 17 est ici en matériau thermoplastique injecté.The control pusher 17 is here injected thermoplastic material.

Le ressort 18 a des extrémités immobilisées en rotation dans le boîtier 2 dans le poussoir de commande 17. Le poussoir de commande 17 comprend ici une fente 27 recevant l'extrémité correspondante du ressort 18 pour immobiliser cette extrémité en rotation par rapport au poussoir. Le ressort 18 a une extrémité opposée en appui contre un rebord interne de l'extrémité 19 et du pivot 16 engagée dans une rainure 29 ménagée dans un pion s'étendant en saillie de la joue 20 correspondante à l'intérieur de l'extrémité 19 du pivot 16. Le ressort 18 est un ressort hélicoïdal agencé pour travailler en compression de manière qu'il tend à ramener le poussoir de commande 17 dans sa position de blocage. En outre, lorsque la chape 7 est dans la position escamotée, le ressort 18 a subi une torsion d'au moins 180° par rapport à son état de repos. Le ressort 18 est ainsi également agencé pour travailler en torsion de manière qu'il tend à maintenir les ergots 24 en appui contre le flanc des tronçons terminaux 14, et ainsi à ramener la chape 7 dans la position sortie de la clé 1.The spring 18 has ends immobilized in rotation in the housing 2 in the control pusher 17. The control pusher 17 here comprises a slot 27 receiving the corresponding end of the spring 18 to immobilize this end in rotation relative to the pusher. The spring 18 has an opposite end bearing against an inner rim of the end 19 and the pivot 16 engaged in a groove 29 formed in a pin projecting from the corresponding cheek 20 inside the end 19 16. The spring 18 is a helical spring arranged to work in compression so that it tends to return the control pusher 17 to its locking position. In addition, when the yoke 7 is in the retracted position, the spring 18 has undergone a twist of at least 180 ° with respect to its rest state. The spring 18 is thus also arranged to work in torsion so that it tends to maintain the lugs 24 resting against the side of the end portions 14, and thus bring the yoke 7 into the extended position of the key 1.

On notera qu'en fonctionnement le poussoir de commande 17 dans sa position de blocage assure aussi bien le maintien de la chape 7 dans la position sortie de la clé 1 que dans la position escamotée de la clé 1. Si les encoches 26 sont délimitées latéralement par des flancs parallèles à la direction de coulissement, il est nécessaire d'enfoncer le poussoir de commande 17 dans sa position de libération pour ramener la clé 1 de sa position sortie à sa position escamotée ou inversement. En revanche, si l'on veut pouvoir ramener la clé 1 de sa position sortie à sa position escamotée sans devoir actionner le poussoir de commande 17, le flanc des encoches 26 se trouvant du côté de la position escamotée (c'est à dire le flanc contre lequel chaque ergot 25 vient en butée lorsqu'on tente de ramener la clé 1 de sa position sortie à sa position escamotée) peut être incliné pour former par glissement sur l'ergot 25 une came de déplacement du poussoir de commande 17 dans sa position de libération.Note that in operation the control pushbutton 17 in its locking position ensures both the maintenance of the yoke 7 in the output position of the key 1 as in the retracted position of the key 1. If the notches 26 are laterally delimited by flanks parallel to the direction of sliding, it is necessary to push the control button 17 in its release position to return the key 1 from its extended position to its retracted position or vice versa. On the other hand, if it is desired to be able to return the key 1 from its extended position to its retracted position without having to actuate the control push-button 17, the side of the notches 26 lying on the side of the retracted position (ie the side against which each lug 25 abuts when attempting to return the key 1 from its extended position to its retracted position) can be inclined to form by sliding on the lug 25 a cam of displacement of the control pusher 17 in its release position.

Le montage de la clé 1 dans le boîtier 2 est réalisé en introduisant la chape 7 équipée de la clé 1 dans l'extrémité du renfoncement latéral 3 du réceptacle 5 et en disposant le pivot 16, le ressort 18 et le poussoir de commande 17 dans le logement 10. L'introduction des ergots 24 dans les tronçons terminaux 14 est réalisée en faisant préalablement pivoter le poussoir de commande 17 par rapport au boîtier 2 et à la chape 7 pour engager les ergots 24 dans les portions d'extrémité 13.1 des tronçons d'entrée 13. Le sens de pivotement est le même que celui qui permet à la chape 7 d'aller de la position sortie à la position escamotée : ce pivotement doit être supérieur à 180° pour exercer une précontrainte en torsion sur le ressort 18. Le poussoir de commande 17 est ensuite enfoncé pour amener le poussoir de commande 17 dans la portion d'extrémité 13.2 du tronçon d'entrée 13. Le ressort 18 se détendant légèrement en torsion (la torsion doit encore être de 180° par rapport à son état de repos) amène les ergots 24 dans les tronçons terminaux 14 et se détendant en compression ramène le poussoir de commande 17 vers sa position de blocage. Le poussoir de commande 17 peut être démonté en effectuant les opérations inverses.The mounting of the key 1 in the housing 2 is carried out by introducing the yoke 7 equipped with the key 1 into the end of the lateral recess 3 of the receptacle 5 and arranging the pivot 16, the spring 18 and the control pusher 17 in the housing 10. The introduction of the lugs 24 in the end sections 14 is achieved by first pivoting the control pusher 17 relative to the housing 2 and the yoke 7 to engage the lugs 24 in the end portions 13.1 sections The pivot direction is the same as that which allows the yoke 7 to go from the extended position to the retracted position: this pivoting must be greater than 180 ° to exert a torsional prestress on the spring 18 The control pusher 17 is then depressed to bring the control pusher 17 into the end portion 13.2 of the inlet section 13. The spring 18 which relaxes slightly in torsion (the torsion must still be 180 ° with respect to its rest state) brings the pins 24 in the end sections 14 and relaxing in compression brings the control pusher 17 to its locking position. The control pushbutton 17 can be disassembled by performing the reverse operations.

On notera par ailleurs que chaque rainure 12 comprend en outre un tronçon additionnel 15 débouchant par une extrémité sur la face externe 9 et par l'autre extrémité dans le tronçon terminal 14 et dans la portion d'extrémité 13.2 de telle manière que la portion d'extrémité 13.2 ne comporte qu'un flanc situé du côté de la face externe 8. Le tronçon additionnel 15 n'a d'autre fonction que de faciliter la fabrication par moulage de la chape 7. Lors du moulage de la chape 7, le logement 10 est réalisé au moyen de deux noyaux mobiles coaxiaux dont les extrémités sont amenées en contact. L'un des noyaux comporte des languettes en saillie externe pour former les portions d'extrémité 13.1 et l'autre des noyaux comporte des languettes en saillie externe pour former les portions d'extrémité 13.2 et les tronçons terminaux 14. Les tronçons additionnels 15 permettent le passage des languettes formant les tronçon terminaux 14 et les portions d'extrémité 13.2.Note further that each groove 12 further comprises an additional section 15 opening at one end on the outer face 9 and the other end in the end section 14 and in the end portion 13.2 so that the portion of end 13.2 has only one flank located on the side of the outer face 8. The additional section 15 has no other function than to facilitate the manufacture by molding of the yoke 7. When molding the yoke 7, the housing 10 is made by means of two coaxial mobile cores whose ends are brought into contact. One of the cores comprises tongues projecting externally to form the end portions 13.1 and the other of the cores comprises tabs projecting externally to form the end portions 13.2 and the terminal sections 14. The additional sections 15 allow the passage of the tabs forming the terminal sections 14 and the end portions 13.2.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiment described and variants may be provided without departing from the scope of the invention as defined by the claims.

En particulier, bien que la rainure ait été représentée avec une forme en J, la rainure peut avoir une autre forme et par exemple une forme en V, le tronçon d'entrée formant un angle aigu avec le tronçon terminal borgne.In particular, although the groove has been shown with a J shape, the groove may have another shape and for example a V shape, the input section forming an acute angle with the blind terminal section.

En outre, le boîtier 2 peut avoir une autre forme que celle représentée et par exemple une forme cylindrique et les positions escamotée et sortie de la clé peuvent être décalées angulairement l'une de l'autre d'un angle différent de 180° et par exemple 90° ou 120°.In addition, the housing 2 may have a shape other than that shown and for example a cylindrical shape and the retracted and exit positions of the key can be angularly offset from each other by an angle other than 180 ° and by example 90 ° or 120 °.
