Description

La présente invention concerne une clé utilisable par exemple pour l'actionnement des serrures de véhicules automobiles.The present invention relates to a key used for example for actuating locks of motor vehicles.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Il existe des clés 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. Une telle clé est par example connue du document US 2003/0000267 A1.There are keys having an integral end of 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. Such a key is known for example from US 2003/0000267 A1.

Dans ces clés, le poussoir de commande est emmanché à force dans le logement de la chape. Cet emmanchement à force engendre des déformations des pièces fragilisant celles-ci et nécessite l'utilisation d'un outillage spécifique relativement coûteux.In these keys, the control pusher is forced into the housing of the yoke. This force fitting causes deformations of the parts weakening them and requires the use of relatively expensive specific tooling.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Un but de l'invention est de fournir un moyen permettant un montage du poussoir ne présentant pas les inconvénients ci-dessus énoncés.An object of the invention is to provide a means for mounting the pusher does not have the disadvantages mentioned above.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

A cet effet, on prévoit, selon l'invention, une clé 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, et un poussoir de commande 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 au moins dans la position escamotée et une position de libération du pivotement de la chape, un ressort étant intercalé entre le boîtier et le poussoir de commande pour rappeler élastiquement la chape dans la position sortie de la clé et le poussoir de commande dans sa position de maintien, le poussoir de commande comprenant au moins un ergot reçu dans une rainure du logement, la rainure comportant 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.For this purpose, it is provided, according to the invention, a key having an integral end of a yoke 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, and a control pusher mounted in a housing of the yoke to be integral in pivoting thereof and to slide between a holding position of the yoke at least in the retracted position and a position of release of the pivoting of the yoke, a spring being interposed between the housing and the control pusher to elastically return the yoke in the output position of the key and the control pusher in its holding position, the control pusher comprising at least one lug received in a groove of the housing, the groove having 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 according to the pivot axis.

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.

Selon un mode de réalisation particulier, le tronçon d'entrée comprend au voisinage de sa première extrémité une portion s'étendant parallèlement à l'axe de pivotement, et au voisinage de sa deuxième extrémité une portion s'étendant selon une direction circonférentielle du logement.According to a particular embodiment, the inlet section comprises in the vicinity of its first end a portion extending parallel to the pivot axis, and in the vicinity of its second end a portion extending in a circumferential direction of the housing .

Le montage du poussoir dans la chape est alors particulièrement pratique.Mounting the pusher in the yoke is then particularly practical.

De préférence, la rainure comprend un tronçon additionnel s'étendant axialement pour déboucher d'une part dans le tronçon terminal et d'autre part sur une face externe de la chape opposée à la face externe sur laquelle débouche le tronçon d'entrée.Preferably, the groove comprises an additional section extending axially to open on the one hand in the terminal section and on the other hand on an outer face of the yoke opposite to the outer face on which the inlet section opens.

Ceci permet de simplifier la fabrication par moulage de la chape en utilisant lors du moulage un noyau mobile pénétrant dans le tronçon d'entrée et un noyau mobile pénétrant par le tronçon additionnel dans le tronçon terminal.This makes it possible to simplify the manufacture by molding the yoke by using during molding a mobile core penetrating into the inlet section and a movable core penetrating the additional section in the terminal section.

De préférence, le poussoir de commande comprend deux ergots et le logement comprend deux rainures, et avantageusement les ergots forment entre eux un angle inférieur à 180°.Preferably, the control pusher comprises two lugs and the housing comprises two grooves, and preferably the lugs form between them an angle less than 180 °.

L'effort d'appui du poussoir de commande sur la chape sous l'effet du ressort est ainsi équilibré tout en ayant un encombrement limité du poussoir de commande et de la chape.The support force of the control pusher on the yoke under the effect of the spring is thus balanced while having a limited space of the control pusher and the yoke.

Selon une caractéristique particulière, la clé comprend un élément d'articulation de la chape dans le boîtier, l'élément d'articulation étant intercalé entre le ressort et le boîtier et comprenant une extrémité montée fixe en rotation dans le boîtier et une extrémité opposée reçue à pivotement dans le logement recevant le poussoir de commande.According to a particular feature, the key comprises a hinge member of the yoke in the housing, the hinge element being interposed between the spring and the housing and comprising an end mounted fixed in rotation in the housing and an opposite end received pivotally in the housing receiving the control pusher.

Ceci permet de simplifier le montage de la chape dans le boîtier.This simplifies the mounting of the yoke in the housing.

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.Other characteristics and advantages will become apparent on reading the following description of a particular non-limiting embodiment of the invention.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La clé conforme à l'invention est ici décrite en tant qu'un dispositif d'actionnement de serrures telles que celles d'un véhicule automobile. En particulier, la clé 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 key according to the invention is here described as a device for actuating locks such as those of a motor vehicle. In particular, the key 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 (portières, de 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 to actuate remotely a centralized locking and unlocking device of the doors (doors, doors and windows). 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 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 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 élément d'articulation généralement désigné en 16 et un poussoir de commande généralement désigné en 17 entre lesquels s'étend un ressort 18.The housing 10 of the yoke 7 accommodates a hinge member generally designated 16 and a control pusher generally designated 17 between which extends a spring 18.

L'élément d'articulation 16 a une forme extérieure cylindrique à contour circulaire et possède une extrémité 19 reçue dans une cavité 20 de l'extrémité du renfoncement latéral 3 recevant la chape 7 et à l'opposé une extrémité 21 reçue à pivotement dans le logement 10 de la chape 7. L'extrémité 19 de l'élément d'articulation 16 et la cavité 20 possèdent des reliefs de forme complémentaire immobilisant l'élément d'articulation 16 en rotation par rapport au boîtier 2. L'extrémité 19 peut ainsi par exemple comprendre des méplats en contact avec des surfaces planes correspondantes de la cavité 20 ou une empreinte excentrée recevant un relief correspondant en saillie de la cavité 20. L'extrémité 21 a une forme extérieure sensiblement cylindrique à section circulaire.The hinge element 16 has a cylindrical outer shape with a circular contour and has an end 19 received in a cavity 20 of the end of the lateral recess 3 receiving the yoke 7 and on the opposite end 21 received pivotally in the housing 10 of the yoke 7. The end 19 of the hinge element 16 and the cavity 20 have reliefs of complementary shape immobilizing the hinge element 16 in rotation relative to the housing 2. The end 19 may thus for example comprise flats in contact with corresponding flat surfaces of the cavity 20 or an eccentric cavity receiving a corresponding relief projecting from the cavity 20. The end 21 has a shape substantially cylindrical outer ring.

Le poussoir de commande 17 a une surface extérieure cylindrique circulaire et possède une portion d'extrémité 22 reçue dans le logement 10 et une portion d'extrémité 23 opposée s'étendant en saillie du logement 10 et du couvercle 5 en passant par une lumière de ce dernier. Deux ergots 24 décalés angulairement l'un par rapport à l'autre de 170° s'étendent en saillie de la portion d'extrémité 22 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 de la portion d'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 control pusher 17 has a circular cylindrical outer surface and has an end portion 22 received in the housing 10 and an opposite end portion 23 projecting from the housing 10 and the cover 5 through a light of this last. Two lugs 24 offset angularly relative to each other by 170 ° project from the end portion 22 and are received in the end portions 14 of the grooves 12 to slide between a locking position of the pivoting of the the clevis 7 and a release position of the pivoting of the yoke 7. In the locking position, two lugs 25 projecting from the end portion 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.

L'élément d'articulation 16 et le poussoir de commande 17 définissent un axe d'articulation et de pivotement de la chape 7 par rapport au boîtier 2. Cet axe d'articulation est confondu avec l'axe central 11.The hinge element 16 and the control pusher 17 define an axis of articulation and pivoting of the yoke 7 with respect to the housing 2. This hinge axis coincides with the central axis 11.

Le ressort 18 a des extrémités immobilisées en rotation dans l'élément d'articulation 16 et 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 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 28 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 articulation member 16 and 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 by compared to the pusher. The spring 18 is a helical spring arranged to work in compression so that it tends to bring the control pushbutton 17 into 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 hold the pins 24 in abutment against the side 28 of the terminal sections 14, and thus to bring the yoke 7 into the extended position of the key 1.

On notera qu'en fonctionnement le poussoir de commande 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 pusher 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 delimited laterally 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 d'une part l'élément d'articulation 16 dans la cavité 20 et le logement 10 et d'autre part le poussoir de commande 17 dans le logement 10 en ayant interposé le ressort 18 entre l'élément d'articulation 16 et le poussoir de commande 17. 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.The mounting of the key 1 in the housing 2 is performed by introducing the clevis 7 equipped with the key 1 in the end of the lateral recess 3 of the receptacle 5 and disposing on the one hand the hinge element 16 in the cavity 20 and the housing 10 and secondly the control button 17 in the housing 10 having interposed the spring 18 between the hinge member 16 and the control pushbutton 17. The insertion of the pins 24 into the terminal sections 14 is achieved by first pivoting the control pushbutton 17 relative to the housing 2 and the yoke 7 to engage the pins 24 in the end portions 13.1 of the inlet sections 13. The direction of rotation 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 torsional prestressing 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 is slightly relaxed in torsion (the torsion must still be 180.degree. at its rest state) brings the pins 24 in the end sections 14 and relaxing in compression brings the control pushbutton 17 to its locking position.

On remarquera que le poussoir de commande 17 peut être démonté en effectuant les opérations inverses.It will be noted that the control pusher 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 portion 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 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 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 a V-shape, the inlet portion forming an acute angle with the blind end portion.

En outre, le boîtier 2 peut avoir d'autres formes 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 other shapes than the one 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 for example 90 ° or 120 °.

De plus, l'élément d'articulation peut être en une seule pièce avec le boîtier.In addition, the hinge member can be in one piece with the housing.
