Description

La présente invention concerne un dispositif de commande comportant un mécanisme de point dur et actionnant des contacts électriques.The present invention relates to a control device comprising a hard point mechanism and actuating electrical contacts.

On connaît déjà, dans l'état de la technique, un dispositif de commande d'une fonction, notamment une fonction mise en oeuvre par un équipement électrique, du type comportant :

  • un organe de commande de fonction, monté déplaçable sur un support fixe entre une position de repos, une position active indexée et une position de sur-course temporaire opposée à la position de repos,
  • des moyens formant point dur, activés lors du déplacement de l'organe de commande de fonction depuis sa position de repos vers sa position active indexée par coopération élastique de cames complémentaires de point dur portées par l'organe de commande de fonction et le support,
    l'organe de commande de fonction étant destiné à coopérer avec un organe de commande de contact électrique par l'intermédiaire d'un organe d'entretoisement élastique lorsque l'organe de commande de fonction est entre sa position active indexée et sa position de sur-course. Le document DE-U-9416060 décrit un tel dispositif.
Already known in the state of the art, a device for controlling a function, in particular a function implemented by an electrical equipment, of the type comprising:
  • a function control member movably mounted on a fixed support between a rest position, an indexed active position and a temporary over-travel position opposite to the home position;
  • hard point means, activated during the movement of the function control member from its rest position to its indexed active position by elastic cooperation of complementary hard point cams carried by the function control member and the support,
    the function control member being adapted to cooperate with an electrical contact control member via an elastic bracing member when the function control member is between its indexed active position and its on position. -race. The document DE-U-9416060 describes such a device.

Un tel dispositif de commande est habituellement destiné à équiper un véhicule automobile, pour la commande d'une fonction telle que le verrouillage/déverrouillage des ouvrants de ce véhicule automobile.Such a control device is usually intended to equip a motor vehicle, for the control of a function such as locking / unlocking the doors of this motor vehicle.

Les moyens formant point dur ont une fonction ergonomique, permettant à un utilisateur de sentir une légère résistance au toucher lors de l'activation de l'organe de commande de fonction.The hard point means has an ergonomic function, allowing a user to feel a slight resistance to touch when activating the function control member.

Ces moyens formant point dur comportent des cames complémentaires habituellement formées par un doigt, porté par l'organe de commande de fonction, et un ressort complémentaire, porté par le support fixe.These hard point means comprise complementary cams usually formed by a finger, carried by the function control member, and a complementary spring carried by the fixed support.

L'organe de commande de contact électrique est monté déplaçable par rapport au support fixe entre des première et seconde positions. Généralement, dans le cas du verrouillage/déverrouillage d'ouvrants, la fonction commandée par le dispositif de commande est dans un premier état (ouvrant verrouillés) lorsque l'organe de commande de contact électrique est dans sa première position, et dans un second état (ouvrants déverrouillés) lorsque cet organe de commande de contact électrique est dans sa seconde position.The electrical contact control member is movably mounted relative to the fixed support between first and second positions. Generally, in the case of the locking / unlocking of sashes, the function controlled by the control device is in a first state (opening locked) when the electrical contact control member is in its first position, and in a second state (unlocked opening) when this electrical contact control member is in its second position.

L'organe d'entretoisement est destiné à transmettre les déplacements de l'organe de commande de fonction à l'organe de commande de contact électrique, de façon que l'organe de commande de contact électrique est dans sa première position lorsque l'organe de commande de fonction est dans sa position de repos, et dans sa seconde position lorsque cet organe de commande de fonction est dans sa position active.The spacer member is adapted to transmit the movements of the function control member to the electrical contact control member, so that the electrical contact control member is in its first position when the organ the function control is in its rest position, and in its second position when the function control member is in its active position.

L'indexage de l'organe de commande de fonction en position active nécessite habituellement que cet organe de commande de fonction puisse se déplacer au delà de la position active, jusqu'à sa position de sur-course temporaire.Indexing the function control member to the active position usually requires that the function control member be movable beyond the active position to its temporary over-travel position.

L'organe d'entretoisement est déformable élastiquement afin d'autoriser ce déplacement entre la position active et la position de sur-course.The spacer member is elastically deformable to allow this movement between the active position and the over-stroke position.

Habituellement, l'organe d'entretoisement est un ressort, une membrane en silicone ou une patte élastique en plastique, de raideur suffisante pour transmettre les déplacements de l'organe de commande de fonction à l'organe de commande de contact électrique.Usually, the spacer member is a spring, a silicone membrane or a plastic elastic tab, of sufficient stiffness to transmit the movements of the function control member to the electrical contact control member.

Le dispositif comporte donc de multiples éléments destinés à réaliser le point dur et l'entretoisement élastique entre l'organe de commande de fonction et l'organe de commande de contact électrique.The device therefore comprises multiple elements intended to achieve the hard point and the elastic bracing between the function control member and the electrical contact control member.

L'invention a notamment pour but de simplifier la structure d'un dispositif de commande du type précité, de façon à réduire le coût et l'encombrement de celui-ci, ceci en ne limitant ni la résistance des éléments de ce dispositif, ni la durée de vie de ce dispositif.The purpose of the invention is in particular to simplify the structure of a control device of the aforementioned type, so as to reduce the cost and the bulk thereof, by limiting neither the resistance of the elements of this device, nor the life of this device.

A cet effet, l'invention a pour objet un dispositif de commande d'une fonction du type précité, comprenant un organe élastique formant à la fois l'organe d'entretoisement élastique et une came élastique de point dur.For this purpose, the subject of the invention is a device for controlling a function of the aforementioned type, comprising an elastic member forming both the elastic bracing member and a hard point elastic cam.

Cet organe élastique est particulièrement avantageux, puisqu'il permet de s'affranchir des multiples éléments classiques formant l'organe d'entretoisement élastique et la came élastique de point dur.This elastic member is particularly advantageous, since it makes it possible to dispense with the multiple conventional elements forming the elastic bracing member and the hard point elastic cam.

La structure du dispositif est donc simplifiée, ce qui facilite la fabrication du dispositif et réduit son coût, puisque l'organe élastique peut être monté dans le dispositif en une seule opération.The structure of the device is simplified, which facilitates the manufacture of the device and reduces its cost, since the elastic member can be mounted in the device in a single operation.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés dans lesquels :

  • la figure 1 est une vue en coupe d'un dispositif de commande selon l'invention, dans lequel l'organe de commande de fonction est dans sa position de repos ;
  • la figure 2 est une vue similaire à la figure 1 du dispositif de la figure 1, dans lequel l'organe de commande de fonction est dans une position intermédiaire entre sa position de repos et sa position active indexée ;
  • la figure 3 est une vue similaire à la figure 1 du dispositif de la figure 1, dans lequel l'organe de commande de fonction est dans sa position active indexée ;
  • la figure 4 est une vue similaire à la figure 1 du dispositif de la figure 1, dans lequel l'organe de commande de fonction est dans sa position de sur-course.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings in which:
  • the figure 1 is a sectional view of a control device according to the invention, wherein the function control member is in its rest position;
  • the figure 2 is a view similar to the figure 1 of the device of the figure 1 wherein the function control member is in an intermediate position between its home position and its indexed active position;
  • the figure 3 is a view similar to the figure 1 of the device of the figure 1 wherein the function control member is in its indexed active position;
  • the figure 4 is a view similar to the figure 1 of the device of the figure 1 wherein the function control member is in its over-travel position.

On a représenté sur les figures 1 à 4 un dispositif de commande d'une fonction selon l'invention, désigné par la référence générale 10.We have shown on Figures 1 to 4 a device for controlling a function according to the invention, designated by the general reference 10.

Le dispositif de commande 10 est habituellement destiné à commander une fonction mise en oeuvre par un équipement électrique 11, telle que le verrouillage/déverrouillage des ouvrants de ce véhicule automobile.The control device 10 is usually intended to control a function implemented by an electrical equipment 11, such as the locking / unlocking of the opening of this motor vehicle.

Le dispositif de commande 10 comporte un organe de commande de fonction 12, monté déplaçable en translation sur un support fixe 14 entre une position de repos, représentée sur la figure 1, une position active indexée, représentée sur la figure 3, et une position de sur-course temporaire, opposée à la position de repos, représentée sur la figure 4.The control device 10 comprises a function control member 12 mounted movably in translation on a fixed support 14 between a rest position, represented on the figure 1 , an indexed active position, represented on the figure 3 , and a position of temporary over-stroke, opposite to the rest position, shown on the figure 4 .

Des moyens I d'indexation classiques de l'organe de commande de fonction 12 en position active sont agencés entre cet organe de commande de fonction 12 et le support 14.Conventional indexing means I of the function control member 12 in the active position are arranged between this function control member 12 and the support 14.

Des moyens élastiques 15 de rappel de l'organe de commande de fonction 12 vers sa position de repos sont également agencés entre l'organe de commande de fonction 12 et le support 14. De préférence, ces moyens élastiques 15 comportent un ressort de compression en appui sur un premier siège ménagé sur l'organe de commande de fonction 12 et un second siège ménagé sur le support 14.Elastic means 15 for returning the function control member 12 to its rest position are also arranged between the function control member 12 and the support 14. Preferably, these elastic means 15 comprise a compression spring in bearing on a first seat formed on the function control member 12 and a second seat formed on the support 14.

Le support fixe 14 forme un corps creux dans lequel est logé un organe élastique 16, de préférence en métal, en forme générale de bande pliée.The fixed support 14 forms a hollow body in which is housed an elastic member 16, preferably metal, generally shaped folded strip.

L'organe élastique 16 comporte une partie de fixation 17 sur le support 14, reliant des première 16A et seconde 16B parties de cet organe élastique 16. La partie de fixation 17 est par exemple fixée au support 14 par collage ou bouterollage.The elastic member 16 has a fastening portion 17 on the support 14, connecting first 16A and second 16B parts of the elastic member 16. The fixing portion 17 is for example fixed to the support 14 by gluing or pegging.

La première partie 16A forme un organe d'entretoisement élastique entre l'organe de commande de fonction 12 et un organe de commande de contact électrique 18 de l'équipement électrique 11, apte à se déplacer par rapport au support 14 entre une première position, dans laquelle l'équipement électrique 11 est dans un premier état, et une seconde position, dans laquelle l'équipement électrique 11 est dans un second état.The first part 16A forms a resilient bracing member between the function control member 12 and an electrical contact control member 18 of the electrical equipment 11, able to move relative to the support 14 between a first position, wherein the electrical equipment 11 is in a first state, and a second position, in which the electrical equipment 11 is in a second state.

L'organe d'entretoisement 16A a une forme générale de bande pliée en épingle déformable élastiquement de manière à former des première 20A et seconde 20B branches.The spacer member 16A has a general shape of elastically deformable pin-folded band so as to form first 20A and second 20B branches.

La première branche 20A de l'organe d'entretoisement 16A est destinée à coopérer avec une extrémité libre de coopération 22A d'un doigt 22 lorsque l'organe de commande de fonction 12 est entre sa position active et sa position de sur-course. Le doigt 22 est relié à l'organe de commande de fonction 12 par une extrémité de liaison 22B de ce doigt 22.The first branch 20A of the spacer member 16A is intended to cooperate with a free engagement end 22A of a finger 22 when the function control member 12 is between its active position and its over-stroke position. The finger 22 is connected to the function control member 12 by a connecting end 22B of the finger 22.

La seconde branche 20B de l'organe d'entretoisement 16A est destinée à coopérer avec l'organe de commande de contact électrique 18 lorsque l'organe de commande de fonction 12 est entre sa position active et sa position de sur-course.The second branch 20B of the spacer member 16A is intended to cooperate with the electrical contact control member 18 when the function control member 12 is between its active position and its over-stroke position.

On notera que l'écartement entre les première 20A et seconde 20B branches de l'organe d'entretoisement 16A est susceptible de varier élastiquement lorsque l'organe de commande de fonction 12 se déplace entre sa position active et sa position de sur-course.It will be noted that the spacing between the first 20A and second 20B branches of the spacer member 16A is likely to vary elastically when the function control member 12 moves between its active position and its over-stroke position.

La seconde partie 16B de l'organe élastique 16 forme une lame élastique, munie d'une extrémité de liaison à la partie de fixation 17 et d'une extrémité d'appui sur le doigt 22.The second portion 16B of the elastic member 16 forms an elastic blade, provided with a connecting end to the fixing portion 17 and a bearing end on the finger 22.

Des moyens 23 formant point dur sont agencés sur l'extrémité d'appui de cette seconde partie 16B de l'organe élastique 16 et le doigt 22.Hard point means 23 are arranged on the bearing end of this second part 16B of the elastic member 16 and the finger 22.

En effet, les moyens 23 formant point dur comportent un profil de came 24 de point dur, formant une came rigide de point dur, ménagé entre les extrémités de coopération 22A et de liaison 22B du doigt 22, destiné à coopérer avec une came élastique complémentaire 26 de point dur ménagée sur l'extrémité d'appui de la seconde partie 16B de l'organe élastique 16,Indeed, the hard point forming means 23 comprise a hard point cam profile 24, forming a hard point rigid cam, formed between the cooperation 22A and the connection 22B end of the finger 22, intended to cooperate with a complementary elastic cam. 26 of hard point formed on the bearing end of the second portion 16B of the elastic member 16,

Les cames complémentaires 24, 26 de point dur sont conformées pour que les moyens 23 formant point dur soient activés lors du déplacement de l'organe de commande de fonction 12 depuis sa position de repos vers sa position active.The complementary cams 24, 26 of hard point are shaped so that the means 23 forming hard point are activated during the movement of the function control member 12 from its rest position to its active position.

On notera que l'organe élastique 16 forme à la fois l'organe d'entretoisement élastique 16A et la came élastique de point dur 26.It will be noted that the elastic member 16 forms both the elastic bracing member 16A and the elastic hard point cam 26.

On précisera ci-dessous les principaux aspects du fonctionnement du dispositif de commande 10 liés à l'invention.The main aspects of the operation of the control device 10 related to the invention will be specified below.

On considère initialement le dispositif de commande 10 dans une position de repos représentée sur la figure 1, dans laquelle l'organe de commande de fonction 12 est dans sa position de repos.The control device 10 is initially considered in a rest position represented on the figure 1 in which the function control member 12 is in its rest position.

Dans cette position de repos, les cames complémentaires de point dur 24, 26 coopèrent entre elles de manière à générer un effet de point dur.In this rest position, the hard point complementary cams 24, 26 cooperate with each other so as to generate a hard point effect.

L'organe d'entretroisement 16A, fixé au support 14 par la partie de fixation 17, ne coopère ni avec l'organe de commande de contact électrique 18, ni avec l'extrémité de coopération 22A du doigt 22.The spacer member 16A, fixed to the support 14 by the fastening portion 17, cooperates neither with the electrical contact control member 18 nor with the engagement end 22A of the finger 22.

Lorsqu'un utilisateur actionne l'organe de commande de fonction 12, il sent une légère résistance au toucher due à l'effet de point dur.When a user actuates the function control member 12, he feels a slight resistance to touch due to the hard point effect.

Sous l'action de l'utilisateur, l'organe de commande de fonction 12 se déplace ensuite en translation vers sa position active, comme cela est représenté sur la figure 2.Under the action of the user, the function control member 12 then moves in translation towards its active position, as shown in FIG. figure 2 .

Les cames complémentaires de point dur 24, 26 glissent alors l'une sur l'autre jusqu'à ce que l'organe de commande de fonction 12 se soit déplacé d'une course prédéterminée, à partir de laquelle les cames complémentaires de point dur 24, 26 ne coopèrent plus entre elles. Dans ce cas, la came élastique 26 coopère avec une surface du doigt 22 parallèle à la direction de déplacement de l'organe de commande de fonction 12, et n'oppose donc plus de résistance au déplacement de cet organe commande de fonction 12.The hard point complementary cams 24, 26 then slide on each other until the function control member 12 has moved a predetermined stroke, from which the hard point complementary cams 24, 26 no longer cooperate with each other. In this case, the elastic cam 26 cooperates with a surface of the finger 22 parallel to the direction of movement of the function control member 12, and therefore no longer opposes the movement of this function control member 12.

Lorsque l'organe de commande de fonction 12 atteint sa position active, l'extrémité de coopération 22A du doigt 22 coopère avec la première branche 20A de l'organe d'entretoisement 16A.When the function control member 12 reaches its active position, the engagement end 22A of the finger 22 cooperates with the first branch 20A of the spacer member 16A.

Cet organe d'entretoisement 16A bascule alors autour de la partie de fixation 17, et la seconde branche 22B vient coopérer avec l'organe de commande de contact électrique 18, et le pousse jusqu'à sa seconde position. L'équipement électrique 11 passe alors dans son second état.This spacer member 16A then tilts around the fastening portion 17, and the second branch 22B cooperates with the electrical contact control member 18, and pushes it to its second position. The electrical equipment 11 then goes into its second state.

Afin d'indexer l'organe de commande de fonction 12 dans sa position active, il est nécessaire de déplacer cet organe de commande de fonction 12 au delà de cette position active, jusqu'à sa position de sur-course, représentée sur la figure 4.In order to index the function control member 12 in its active position, it is necessary to move this function control member 12 beyond this active position, to its over-stroke position, shown in FIG. figure 4 .

Dans cette position de sur-course, le doigt 22 continue de pousser l'organe d'entretoisement 16A vers l'organe de commande de contact électrique 18.In this position of over-stroke, the finger 22 continues to push the spacer member 16A towards the electrical contact control member 18.

L'organe d'entretoisement 16A se déforme alors élastiquement, l'écartement entre ses première 20A et seconde 20B branches diminuant de façon élastique.The spacer member 16A then deforms elastically, the spacing between its first 20A and second 20B branches decreasing elastically.

Dans cette position, la seconde branche 20B coopère toujours avec l'organe de commande de contact électrique 18, qui reste ainsi dans sa seconde position.In this position, the second branch 20B always cooperates with the electrical contact control member 18, which thus remains in its second position.

Conformément à un fonctionnement classique des moyens d'indexation I, lorsque l'utilisateur relâche l'organe de commande de fonction 12, celui ci remonte en position active grâce aux moyens de rappel élastique 15, cette position étant indexée grâce aux moyens d'indexation I.In accordance with a conventional operation of the indexing means I, when the user releases the function control member 12, the latter goes up to the active position thanks to the elastic return means 15, this position being indexed by the indexing means I.

Si l'utilisateur actionne à nouveau l'organe de commande de fonction 12 jusqu'à sa position de sur-course, puis le relâche, les moyens d'indexation I sont libérés et l'organe de commande de fonction 12 est alors rappelé dans sa position de repos telle que représentée sur la figure 1.If the user again actuates the function control member 12 to its over-travel position, then releases it, the indexing means I are released and the function control member 12 is then recalled in its rest position as shown on the figure 1 .

On notera enfin que l'invention n'est pas limitée au mode de réalisation précédemment décrit.Finally, it should be noted that the invention is not limited to the embodiment previously described.

Un dispositif de commande de fonction selon l'invention peut notamment être destiné à commander d'autres fonctions, telles que l'éclairage, le dégivrage d'une vitre, la climatisation, etc.A function control device according to the invention may in particular be intended to control other functions, such as lighting, defrosting a window, air conditioning, etc.
