Description

Domaine technique de l'inventionTechnical field of the invention

L'invention relève du domaine de l'horlogerie, et notamment des dispositifs de commande de mouvement horlogers de pièces d'horlogerie, telle que des montres.The invention relates to the field of watchmaking, and in particular devices for controlling the movement of timepieces, such as watches.

L'invention concerne en particulier un dispositif de commande d'un mouvement horloger avec retour tactile et une pièce d'horlogerie, notamment une montre, comprenant un tel dispositif de commande.The invention relates in particular to a device for controlling a watch movement with tactile feedback and a timepiece, in particular a watch, comprising such a control device.

Arrière-plan technologiqueTechnology background

Dans le domaine de l'horlogerie, les dispositifs de commande, tels que les boutons poussoirs ou les couronnes à poussoir, permettent la commande et/ou le réglage de mouvements horlogers mécaniques ou électroniques disposés à l'intérieur d'un boitier d'une pièce d'horlogerie, par exemple d'une montre.In the field of watchmaking, control devices, such as push buttons or push crowns, allow the control and/or adjustment of mechanical or electronic watch movements arranged inside a case of a timepiece, for example a watch.

Plus particulièrement, les dispositifs de commande peuvent être destinés, par exemple, au remontage, à la mise à l'heure ou au réglage de toute fonction d'un mouvement horloger.More particularly, the control devices can be intended, for example, for winding, setting the time or adjusting any function of a watch movement.

Les dispositifs de commande de l'état de la technique sont au moins déplaçables en translation par rapport au boitier entre une position active, de réglage et/ou de commande, et une position inactive, de repos. A cet effet, les dispositifs de commande comprennent généralement une tête s'étendant radialement à l'extérieur du boitier de sorte à pouvoir être manipulée par un utilisateur.The control devices of the state of the art are at least movable in translation relative to the housing between an active, adjustment and/or control position, and an inactive, rest position. For this purpose, the control devices generally comprise a head extending radially outside the housing so that it can be manipulated by a user.

Typiquement, la tête est reliée à la tige de réglage, qui est adaptée à agir, directement ou non, sur le mouvement horloger lors du déplacement de ladite tête.Typically, the head is connected to the adjustment rod, which is adapted to act, directly or indirectly, on the watch movement when said head moves.

Il existe un besoin pour l'utilisateur de ressentir lorsqu'il provoque le changement de position du dispositif de commande par la manipulation de la tête. Ce besoin est d'autant plus notable lorsque la pièce d'horlogerie comporte un mouvement horloger électronique.There is a need for the user to feel when causing the position of the controller to change by manipulating the head. This need is all the more notable when the timepiece includes an electronic watch movement.

En effet, généralement, les dispositifs de commande de mouvements horlogers mécaniques actionnent des mobiles dudit dispositif lorsqu'ils évoluent entre leurs positions active et inactive, de sorte que l'utilisateur ressente un retour tactile sous la forme d'une légère résistance.Indeed, generally, devices for controlling mechanical watch movements activate the mobiles of said device when they move between their active and inactive positions, so that the user feels tactile feedback in the form of a slight resistance.

Toutefois, cette résistance peut ne pas être suffisante pour provoquer un retour tactile remarquable pour l'utilisateur, c'est-à-dire qu'il peut ne pas le ressentir.However, this resistance may not be sufficient to cause remarkable tactile feedback for the user, i.e. they may not feel it.

Le document EP 3 245 563 B1 divulgue un dispositif de commande d'un mouvement horloger comprenant un module élastique.The document EP 3 245 563 B1 discloses a device for controlling a watch movement comprising an elastic module.

Résumé de l'inventionSummary of the invention

L'invention répond à ce besoin en fournissant une solution de dispositif de commande d'un mouvement horloger procurant un retour tactile à un utilisateur lorsque ce dernier modifie la position dudit dispositif de commande, ledit retour tactile étant d'une intensité suffisante pour être ressenti par un utilisateur.The invention meets this need by providing a solution for a device for controlling a watch movement providing tactile feedback to a user when the latter modifies the position of said control device, said tactile feedback being of sufficient intensity to be felt. by a user.

Plus précisément, l'invention concerne un dispositif de commande d'un mouvement horloger comportant d'une part, une première partie comprenant un tube de guidage en coulissement destiné à être fixe par rapport audit mouvement horloger, et d'autre part, une seconde partie mobile guidée en coulissement par le tube de guidage selon une direction dite « direction axiale », relativement à ladite première partie, entre une position active dans laquelle elle est apte à être solidaire, par le biais d'une tige de réglage, à un composant du mouvement horloger, et une position inactive dans laquelle ladite tige de réglage est destinée à libérer le composant du mouvement horloger.More precisely, the invention relates to a device for controlling a watch movement comprising on the one hand, a first part comprising a sliding guide tube intended to be fixed relative to said watch movement, and on the other hand, a second movable part guided in sliding by the guide tube in a direction called "axial direction", relative to said first part, between an active position in which it is able to be secured, by means of an adjustment rod, to a component of the watch movement, and an inactive position in which said adjustment rod is intended to release the component from the watch movement.

La seconde partie comprend une tête coiffant un module d'emboîtage élastique réversible fixé à la tige de réglage et agencé de sorte à occuper un état de repos lorsque la seconde partie occupe les positions active et inactive et étant sollicité par le tube de guidage lorsque la seconde partie évolue entre ces positions.The second part comprises a head covering a reversible elastic nesting module fixed to the adjustment rod and arranged so as to occupy a rest state when the second part occupies the active and inactive positions and being biased by the guide tube when the second part evolves between these positions.

Ainsi, lors de sa manipulation, en particulier sa translation, par un utilisateur, la seconde partie va à l'encontre d'efforts d'emboîtage élastique lors de son changement de position, ce qui provoque une sensation de retour tactile à l'utilisateur et plus précisément, une sensation d'indexation, indiquant à l'utilisateur le changement de position de la seconde partie.Thus, during its manipulation, in particular its translation, by a user, the second part goes against elastic nesting forces during its change of position, which causes a sensation of tactile feedback to the user and more precisely, a sensation of indexing, indicating to the user the change in position of the second part.

Par ailleurs, les efforts d'emboîtage élastique étant générés par le module d'emboitage élastique logé au sein du dispositif de commande, et plus particulièrement coiffé par la tête, le retour tactile est d'une intensité suffisante pour être ressenti par un utilisateur.Furthermore, the elastic nesting forces being generated by the elastic nesting module housed within the control device, and more particularly covered by the head, the tactile feedback is of sufficient intensity to be felt by a user.

Dans des modes particuliers de réalisation, lorsqu'il sollicite le module d'emboitage élastique, le tube de guidage exerce, par une saillie radiale, un effort allant à l'encontre d'une force de rappel élastique de direction radiale, cet effort étant à l'origine de l'effort d'emboitage élastique.In particular embodiments, when it biases the elastic fitting module, the guide tube exerts, through a radial projection, a force going against an elastic return force in a radial direction, this force being at the origin of the elastic nesting force.

Dans des modes particuliers de réalisation de l'invention, la saillie radiale est formée par une lèvre, par exemple annuaire, agencée à une extrémité du tube de guidage.In particular embodiments of the invention, the radial projection is formed by a lip, for example directory, arranged at one end of the guide tube.

Dans des modes particuliers de réalisation de l'invention, le tube de guidage présente une forme de cylindre étagé, comprenant une première portion cylindrique dont une surface périphérique externe guidé en translation par une paroi périphérique d'une cavité borgne de la tête, et comprenant une seconde portion cylindrique dont une surface périphérique interne est guidée en translation autour de la tige de réglage.In particular embodiments of the invention, the guide tube has the shape of a stepped cylinder, comprising a first cylindrical portion including an external peripheral surface guided in translation by a peripheral wall of a blind cavity of the head, and comprising a second cylindrical portion of which an internal peripheral surface is guided in translation around the adjustment rod.

Dans des modes particuliers de réalisation de l'invention, le tube de guidage comporte un épaulement entre ses deux portions cylindriques, la première portion recevant un organe élastique agencé en appui contre ledit épaulement et le module d'emboîtage élastique, ledit organe travaillant en compression de sorte à générer une force tendant à éloigner le module d'emboitage élastique du tube de guidage.In particular embodiments of the invention, the guide tube comprises a shoulder between its two cylindrical portions, the first portion receiving an elastic member arranged to bear against said shoulder and the elastic nesting module, said member working in compression so as to generate a force tending to move the elastic fitting module away from the guide tube.

Dans des modes particuliers de réalisation de l'invention, la première portion du tube de guidage comporte une creusure recevant le module d'emboitage élastique lorsque la seconde partie occupe la position active, ledit module d'emboitage élastique étant en retrait de ladite creusure lorsque la seconde partie occupe la position active.In particular embodiments of the invention, the first portion of the guide tube comprises a recess receiving the elastic nesting module when the second part occupies the active position, said elastic nesting module being set back from said recess when the second part occupies the active position.

Dans des modes particuliers de réalisation de l'invention, le module d'emboitage élastique est interposé entre la tige de réglage et la tête, de sorte que la tête soit fixée à tige de réglage par le biais du module d'emboitage élastique.In particular embodiments of the invention, the elastic fitting module is interposed between the adjustment rod and the head, so that the head is fixed to the adjustment rod via the elastic fitting module.

Dans des modes particuliers de réalisation de l'invention, le module d'emboitage élastique comprend une cage s'étendant entre deux parois d'extrémités reliées l'une à l'autre par une paroi périphérique, les parois d'extrémités étant respectivement fixées à la tête et à la tige de réglage.

Description détaillée de l'inventionDetailed description of the invention

Les figures 1 et 2 montrent un exemple préféré d'un dispositif de commande 10 d'un mouvement horloger selon la présente invention.THE figures 1 and 2 show a preferred example of a device 10 for controlling a watch movement according to the present invention.

Le dispositif de commande 10 peut prendre la forme d'une couronne à poussoir, couronne de remontoir ou toute couronne ou bouton permettant d'agir sur le mouvement horloger par une pression de l'utilisateur.The control device 10 can take the form of a push-button crown, winding crown or any crown or button allowing the watch movement to be actuated by pressure from the user.

Le dispositif de commande 10 est destiné à être engagé à travers une carrure d'un boitier d'une pièce d'horlogerie, en particulier d'une montre, de façon connue de l'homme du métier, dans lequel est logé le mouvement horloger.The control device 10 is intended to be engaged through a middle part of a case of a timepiece, in particular of a watch, in a manner known to those skilled in the art, in which the watch movement is housed .

Plus particulièrement, à cet effet, le dispositif de commande 10 selon l'invention comporte une première partie comprenant un tube de guidage 11 en coulissement destiné à être engagé fixement dans un orifice traversant s'étendant radialement dans la carrure. Autrement dit, le tube de guidage 11 est destiné à être fixe par rapport au mouvement horloger.More particularly, for this purpose, the control device 10 according to the invention comprises a first part comprising a sliding guide tube 11 intended to be fixedly engaged in an orifice crossing extending radially in the caseband. In other words, the guide tube 11 is intended to be fixed relative to the watch movement.

Par ailleurs, le dispositif de commande 10 comporte une seconde partie 12 comprenant une tige de réglage 120 s'étendant à travers le tube de guidage 11, ladite tige étant fixée, par l'une de ses extrémités, à un module d'emboîtage élastique 130 réversible. La seconde partie 12 comprend également une tête 140 coiffant le module d'emboitage élastique 130, comme décrit plus en détail ci-après.Furthermore, the control device 10 comprises a second part 12 comprising an adjustment rod 120 extending through the guide tube 11, said rod being fixed, by one of its ends, to an elastic nesting module 130 reversible. The second part 12 also includes a head 140 covering the elastic fitting module 130, as described in more detail below.

La tige de réglage 120 est engagée en coulissement selon une direction axiale à travers le tube de guidage 11, de sorte que la seconde partie 12 coulisse par rapport à la première partie entre une position active, représentée sur la figure 2, dans laquelle la tige de réglage 120 est apte à être solidaire d'un composant du mouvement horloger, et une position inactive, représentée sur la figure 1, dans laquelle la tige de réglage 120 est apte à libérer le composant du mouvement horloger, c'est-à-dire qu'elle n'est pas solidaire de ce dernier.The adjustment rod 120 is engaged in sliding in an axial direction through the guide tube 11, so that the second part 12 slides relative to the first part between an active position, shown on the figure 2 , in which the adjustment rod 120 is able to be integral with a component of the watch movement, and an inactive position, shown on the figure 1 , in which the adjustment rod 120 is capable of releasing the component of the watch movement, that is to say that it is not integral with the latter.

Ce changement de position de la seconde partie est provoqué par pression de la tête 140 par un utilisateur de la montre.This change in position of the second part is caused by pressure on the head 140 by a user of the watch.

En d'autres termes, lorsque la seconde partie 12 occupe la position active, elle est rétractée par rapport à la première partie et lorsque la seconde partie 12 occupe la position inactive, elle est déployée par rapport à la première partie.In other words, when the second part 12 occupies the active position, it is retracted relative to the first part and when the second part 12 occupies the inactive position, it is deployed relative to the first part.

Dans le présent texte, on entend par le terme « solidaire », que deux pièces sont reliées cinématiquement ensemble de sorte que l'une puisse transmettre un mouvement ou un effort à l'autre. Autrement dit, lorsque la tige de réglage 120 est solidaire du mouvement horloger, elle peut agir sur ce dernier.In the present text, the term “connected” means that two parts are kinematically connected together so that one can transmit a movement or an effort to the other. In other words, when the adjustment rod 120 is integral with the watch movement, it can act on the latter.

Avantageusement, le dispositif de commande 10 selon l'invention est configuré de sorte que le module d'emboîtage élastique 130 occupe un état de repos lorsque la seconde partie 12 occupe les positions inactive et active, et est sollicité, c'est-à-dire contraint, par le tube de guidage 11 lorsque la seconde partie 12 évolue entre ces positions.Advantageously, the control device 10 according to the invention is configured so that the elastic nesting module 130 occupies a rest state when the second part 12 occupies the inactive and active positions, and is requested, that is to say constrained, by the guide tube 11 when the second part 12 moves between these positions.

Grâce à cette caractéristique, lorsque l'utilisateur manipule, plus précisément presse, le dispositif de commande 10 de sorte à translater la seconde partie 12 jusqu'à sa position active, il va notamment ponctuellement à l'encontre d'efforts d'emboîtage élastique. L'utilisateur ressent donc une brève résistance mécanique, et ce jusqu'à ce que la seconde partie 12 atteigne sa positions active, dans laquelle un élément élastique, décrit en détail ci-après, n'exerce plus d'efforts d'emboitage élastique, l'utilisateur ressentant alors une libération de ces efforts.Thanks to this characteristic, when the user manipulates, more precisely presses, the control device 10 so as to translate the second part 12 to its active position, it goes in particular occasionally against elastic nesting efforts . The user therefore feels a brief mechanical resistance, until the second part 12 reaches its active position, in which an elastic element, described in detail below, no longer exerts elastic engagement forces. , the user then feeling a release from these efforts.

Ainsi, le dispositif de commande 10 provoque chez l'utilisateur, lorsqu'il manipule la seconde partie 12 telle décrit précédemment, une sensation de retour tactile, et plus précisément, une sensation franche d'indexation.Thus, the control device 10 causes in the user, when manipulating the second part 12 as described above, a sensation of tactile feedback, and more precisely, a clear sensation of indexing.

Un exemple particulier de réalisation de l'invention représenté sur les figures 1 et 2 est décrit plus en détail ci-après.A particular example of embodiment of the invention represented on the figures 1 and 2 is described in more detail below.

Comme le montrent les figures 1 et 2, la tête 140 présente une cavité 141 borgne de forme sensiblement cylindrique, définie par une paroi de fond 142 et par une paroi périphérique 143.As shown in the figures 1 and 2 , the head 140 has a blind cavity 141 of substantially cylindrical shape, defined by a bottom wall 142 and by a peripheral wall 143.

Avantageusement, la cavité 141 reçoit le module d'emboitage élastique 130, ce dernier étant fixé contre la paroi de fond 142, soit par chassage, soit par collage.Advantageously, the cavity 141 receives the elastic fitting module 130, the latter being fixed against the bottom wall 142, either by driving in or by gluing.

Le module d'emboitage élastique 130 comprend une cage de forme sensiblement cylindrique s'étendant entre deux parois d'extrémités 131 et 132 reliées l'une à l'autre par une paroi périphérique 133.The elastic nesting module 130 comprises a cage of substantially cylindrical shape extending between two end walls 131 and 132 connected to each other by a peripheral wall 133.

En particulier, la cage est fixée à la tête 140 par une première paroi d'extrémité 131, présentant préférentiellement une section droite de forme complémentaire de celle de la cavité 141, notamment de celle de la paroi de fond 142 de ladite cavité 141.In particular, the cage is fixed to the head 140 by a first end wall 131, preferably having a straight section of shape complementary to that of the cavity 141, in particular to that of the bottom wall 142 of said cavity 141.

La cage est fixée, par une seconde paroi d'extrémité 132, à la tige de réglage 120. Autrement dit, le module d'emboitage élastique 130 est interposé entre la tige de réglage 120 et la tête 140, de sorte que ladite tête 140 soit fixée à tige de réglage 120 par le biais dudit module.The cage is fixed, by a second end wall 132, to the adjustment rod 120. In other words, the elastic fitting module 130 is interposed between the adjustment rod 120 and the head 140, so that said head 140 is fixed to adjustment rod 120 via said module.

Par ailleurs, comme visible sur les figures 1 et 2, la cage reçoit un élément élastique s'étendant radialement à travers ladite cage et faisant sailli, par au moins l'une de ses extrémités, à travers la paroi périphérique 133.Furthermore, as visible on the figures 1 and 2 , the cage receives an elastic element extending radially through said cage and projecting, through at least one of its ends, through the peripheral wall 133.

Plus précisément, dans une forme de réalisation, l'élément élastique comporte une semelle 134 fixée à la paroi périphérique 133 et un coulisseau 135 engagé de manière mobile en translation dans un orifice traversant de la paroi périphérique 133, de sorte à s'étendre au-delà de ladite paroi périphérique 133.More precisely, in one embodiment, the elastic element comprises a sole 134 fixed to the peripheral wall 133 and a slide 135 engaged in a movable manner in translation in a through hole in the peripheral wall 133, so as to extend to the beyond said peripheral wall 133.

Le coulisseau 135 et la semelle 134 sont diamétralement opposés au sein de la cage et ledit coulisseau 135 est adapté à translater selon une direction perpendiculaire à la direction de coulissement de la tige de réglage 120.The slide 135 and the sole 134 are diametrically opposed within the cage and said slide 135 is adapted to translate in a direction perpendicular to the direction of sliding of the adjustment rod 120.

Le coulisseau 135 et la semelle 134 sont reliés l'un à l'autre par un organe élastique 136, lequel travaillant en compression soumet ledit coulisseau 135 à une force de rappel élastique tendant à l'éloigner de la semelle 134, ladite force de rappel élastique étant à l'origine de l'effort d'emboitage élastique.The slider 135 and the sole 134 are connected to each other by an elastic member 136, which working in compression subjects said slider 135 to an elastic restoring force tending to move it away from the sole 134, said restoring force elastic being at the origin of the elastic nesting effort.

Le coulisseau 135 présente une extrémité proximale par laquelle il est fixé à l'organe élastique 136 qui est formé, dans l'exemple préféré de réalisation représenté sur les figures 1 et 2, par un ressort à spires, et une extrémité distale par laquelle il fait sailli au-delà de la cage.The slide 135 has a proximal end by which it is fixed to the elastic member 136 which is formed, in the preferred embodiment shown on the figures 1 and 2 , by a coil spring, and a distal end through which it projects beyond the cage.

Entre l'extrémité distale et l'extrémité proximale, le coulisseau 135 comporte une collerette 137 radiale agencée en butée contre la paroi périphérique 133 de la cage, lorsque le module d'emboîtage élastique 130 occupe l'état de repos. Une autre fonction de la collerette 137 est de guider le coulisseau 135 en translation, ladite collerette 137 étant ajustée entre les première et seconde parois d'extrémités avec un jeu mécanique autorisant le déplacement du coulisseau 135.Between the distal end and the proximal end, the slide 135 comprises a radial flange 137 arranged in abutment against the wall peripheral 133 of the cage, when the elastic nesting module 130 occupies the rest state. Another function of the flange 137 is to guide the slide 135 in translation, said flange 137 being adjusted between the first and second end walls with a mechanical clearance allowing the movement of the slide 135.

Dans l'exemple préféré de réalisation, le coulisseau 135 est également guidé en translation par une portion cylindrique par laquelle il est engagé à travers la cage, et plus particulièrement, à travers un orifice de la cage, dont la section droite présente une forme complémentaire de celle de la section droite de la portion cylindrique.In the preferred embodiment, the slide 135 is also guided in translation by a cylindrical portion by which it is engaged through the cage, and more particularly, through an orifice of the cage, the cross section of which has a complementary shape of that of the straight section of the cylindrical portion.

Le coulisseau 135 comporte à son extrémité distale une forme hémisphérique 138 contre laquelle est destiné à venir en appui le tube de guidage 11 lors du déplacement de la seconde partie 12 par rapport à la première partie entre les positions active et inactive, comme décrit plus en détail ci-après.The slide 135 has at its distal end a hemispherical shape 138 against which the guide tube 11 is intended to bear during the movement of the second part 12 relative to the first part between the active and inactive positions, as described further below. detail below.

Dans une autre forme de réalisation de l'élément élastique représentée sur la figure 3, ce dernier comporte, à la place de la semelle 134, un autre coulisseau 135. Les deux coulisseaux 135 sont alors destinés à être sollicités de façon concomitante par le tube de guidage 11 lorsque la seconde partie 12 évolue entre les positions actives et inactives.In another embodiment of the elastic element shown in the Figure 3 , the latter comprises, in place of the sole 134, another slide 135. The two slides 135 are then intended to be urged simultaneously by the guide tube 11 when the second part 12 moves between the active and inactive positions.

Dans encore une autre forme de réalisation de l'élément élastique représentée sur la figure 4, le coulisseaux 135 est formé par une bille dépassant au-delà de la cage, ladite bille présentant un diamètre supérieur à celui de l'orifice à travers lequel elles sont engagées. Alternativement, l'orifice peut présenter des moyens de retenue de ladite bille, tel qu'une réduction de section.In yet another embodiment of the elastic element shown on the figure 4 , the slider 135 is formed by a ball projecting beyond the cage, said ball having a diameter greater than that of the orifice through which they are engaged. Alternatively, the orifice may have means for retaining said ball, such as a reduction in section.

Dans une autre forme de réalisation de l'invention, l'élément élastique comporte, à la place de la semelle 134, un autre coulisseau 135 et les coulisseaux sont formés par des billes.In another embodiment of the invention, the elastic element comprises, in place of the sole 134, another slide 135 and the slides are formed by balls.

La seconde paroi d'extrémité 132 de la cage comprend des moyens de fixation à la tige de réglage 120. Préférentiellement, ces moyens de fixation peuvent être formés par un trou taraudé central avec lequel coopère en vissage une extrémité, dite « extrémité proximale », filetée, de la tige de réglage 120, ou bien un alésage central traversant avec lequel coopère en ajustement serré ladite extrémité proximale de la tige de réglage 120.The second end wall 132 of the cage comprises means for fixing to the adjustment rod 120. Preferably, these fixing means can be formed by a central threaded hole with which one end, called the "proximal end", cooperates in screwing. threaded, of the adjustment rod 120, or else a central through bore with which cooperates in tight fit said proximal end of the adjustment rod 120.

A cet effet, la tige de réglage 120 peut, en outre, comporter au niveau de l'extrémité proximale, un épaulement annulaire 121 destiné à venir en butée contre la seconde paroi d'extrémité 132. Plus particulièrement, l'épaulement annulaire 121 est destiné à venir en butée contre un bossage s'étendant autour du trou taraudé ou de l'alésage central de la cage.For this purpose, the adjustment rod 120 may, in addition, comprise at the level of the proximal end, an annular shoulder 121 intended to abut against the second end wall 132. More particularly, the annular shoulder 121 is intended to abut against a boss extending around the tapped hole or the central bore of the cage.

Par ailleurs, la tige de réglage 120 comporte une butée distale 122, formée dans l'exemple préféré de réalisation de l'invention par un anneau élastique logé dans une gorge annulaire s'étendant radialement dans ladite tige de réglage 120.Furthermore, the adjustment rod 120 comprises a distal stop 122, formed in the preferred embodiment of the invention by an elastic ring housed in an annular groove extending radially in said adjustment rod 120.

Le tube de guidage 11 est en appui contre la butée distale lorsque la seconde partie 12 occupe la position inactive, comme le montre la figure 1.The guide tube 11 rests against the distal stop when the second part 12 occupies the inactive position, as shown in figure 1 .

Le tube de guidage 11 présente préférentiellement deux zones de guidage en translation par rapport à la seconde partie 12.The guide tube 11 preferably has two guide zones in translation relative to the second part 12.

Plus particulièrement, dans l'exemple préféré de réalisation de l'invention, le tube de guidage 11 présente une forme de cylindre étagé comprenant une première portion cylindrique et une seconde portion cylindrique. Comme illustré sur les figures, la première portion cylindrique présente un diamètre supérieur à la seconde portion cylindrique.More particularly, in the preferred embodiment of the invention, the guide tube 11 has the shape of a stepped cylinder comprising a first cylindrical portion and a second cylindrical portion. As illustrated in the figures, the first cylindrical portion has a diameter greater than the second cylindrical portion.

La première portion cylindrique est engagée dans la cavité 141 de la tête 140, ladite première portion cylindrique comportant une paroi périphérique 110 dont la surface externe coopère en coulissement par ajustement glissant avec la paroi périphérique 143 de la tête 140. En particulier, la paroi périphérique 110 peut comprendre une portée annulaire 111 prévue pour glisser contre la paroi périphérique 143 de la tête 140.The first cylindrical portion is engaged in the cavity 141 of the head 140, said first cylindrical portion comprising a peripheral wall 110 whose external surface cooperates in sliding by sliding fit with the peripheral wall 143 of the head 140. in particular, the peripheral wall 110 may comprise an annular surface 111 intended to slide against the peripheral wall 143 of the head 140.

La première portion cylindrique comprend une extrémité libre, opposée à la seconde portion cylindrique, comprenant une saillie radiale 112 prévue pour exercer un effort contre le coulisseau 135 allant à l'encontre de la force de rappel élastique exercé par l'organe élastique 136, lorsque le tube de guidage 11 sollicite le module d'emboîtage élastique 130.The first cylindrical portion comprises a free end, opposite the second cylindrical portion, comprising a radial projection 112 intended to exert a force against the slide 135 going against the elastic return force exerted by the elastic member 136, when the guide tube 11 biases the elastic nesting module 130.

Cet effort participe à générer les efforts d'emboitage élastique.This effort contributes to generating the elastic nesting forces.

Plus précisément, la saillie radiale 112 est formée par une lèvre s'étendant vers l'intérieur de la première portion cylindrique. On définit ici comme « l'intérieur » de la première portion cylindrique, le volume interne délimité par une surface interne de la paroi périphérique 110.More precisely, the radial projection 112 is formed by a lip extending towards the inside of the first cylindrical portion. We define here as “the interior” of the first cylindrical portion, the internal volume delimited by an internal surface of the peripheral wall 110.

Comme le montrent les figures 1 et 2, dans l'exemple préféré de réalisation de l'invention, la surface interne de la paroi périphérique 110 de la première portion cylindrique comprend une creusure 113 annulaire en regard du volume interne. Cette creusure 113 est destinée à dégager un volume suffisant pour loger le module d'emboitage élastique 130 lorsque la seconde partie 12 occupe la position active, comme représenté sur la figure 2.As shown in the figures 1 and 2 , in the preferred embodiment of the invention, the internal surface of the peripheral wall 110 of the first cylindrical portion comprises an annular recess 113 facing the internal volume. This recess 113 is intended to release a sufficient volume to accommodate the elastic fitting module 130 when the second part 12 occupies the active position, as shown in the figure. figure 2 .

La première portion cylindrique comprend une paroi de fond 114 par laquelle elle est reliée à la seconde portion cylindrique. Ladite paroi de fond 114 forme un épaulement contre lequel est avantageusement agencé en appui un organe élastique 115 logé à l'intérieur de ladite première portion cylindrique. L'organe élastique 115 est en outre agencé en appui contre le module d'emboîtage élastique 130 et travaille en compression de sorte à générer une force tendant à éloigner la tête 140 et le module d'emboitage élastique 130 du tube de guidage 11.The first cylindrical portion comprises a bottom wall 114 by which it is connected to the second cylindrical portion. Said bottom wall 114 forms a shoulder against which is advantageously arranged to bear an elastic member 115 housed inside said first cylindrical portion. The elastic member 115 is further arranged to rest against the elastic nesting module 130 and works in compression so as to generate a force tending to move the head 140 and the elastic nesting module 130 away from the guide tube 11.

Ainsi, lorsque l'utilisateur relâche la pression exercée sur la tête, la seconde partie 12 est entraînée vers la position inactive par l'organe élastique 115. L'utilisateur accompagnant la seconde partie 12 dans son déplacement jusqu'à la position inactive, il ressent les efforts d'emboitage élastique lorsque la saillie radiale 112 entre en contact contre le coulisseau 135 et contraint ponctuellement l'organe élastique 136, et par conséquent, il ressent la sensation de retour tactile.Thus, when the user releases the pressure exerted on the head, the second part 12 is driven towards the inactive position by the member elastic 115. The user accompanying the second part 12 in its movement to the inactive position, he feels the elastic nesting forces when the radial projection 112 comes into contact against the slide 135 and punctually constrains the elastic member 136, and hence he feels the sensation of tactile feedback.

La seconde portion cylindrique est emmanchée autour de la tige de réglage 120, ladite seconde portion cylindrique comportant une paroi périphérique 116 dont la surface interne coopère en coulissement par ajustement glissant avec ladite tige de réglage 120.The second cylindrical portion is fitted around the adjustment rod 120, said second cylindrical portion comprising a peripheral wall 116 whose internal surface cooperates in sliding by sliding adjustment with said adjustment rod 120.

En outre, la seconde portion cylindrique comporte un chambrage 117 recevant des joints d'étanchéité interposés entre la paroi périphérique de la seconde portion cylindrique et la tige de réglage 120.Furthermore, the second cylindrical portion includes a recess 117 receiving seals interposed between the peripheral wall of the second cylindrical portion and the adjustment rod 120.

Enfin, la seconde portion cylindrique comprend une extrémité libre opposée à la première portion cylindrique, laquelle est prévue pour venir en appui contre la butée distale de la tige de réglage 120 lorsque la seconde partie 12 occupe la position inactive.Finally, the second cylindrical portion comprises a free end opposite the first cylindrical portion, which is intended to come to bear against the distal stop of the adjustment rod 120 when the second part 12 occupies the inactive position.
