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 to 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 technologiqueTechnological 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 may 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 as to be able to 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 is moved.

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 he causes the change in position of the control device 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 atteignent leurs positions active et/ou inactive, de sorte que l'utilisateur ressente un retour tactile sous la forme d'une légère résistance, tel que divulgué dans les documents CH716210A2 ou CH707634A2 par exemple.Indeed, generally, mechanical watch movement control devices actuate mobiles of said device when they reach their active and/or inactive positions, so that the user feels tactile feedback in the form of a slight resistance, as disclosed in the documents CH716210A2 Or CH707634A2 For example.

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 elicit noticeable tactile feedback for the user, i.e., the user may not feel it.

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 control device for 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 caractérisé en ce qu'il comporte d'une part, une première partie comprenant un tube de guidage en coulissement destiné à être fixe par rapport audit mouvement horloger et un module d'activation, 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, ladite seconde partie comprenant un coulisseau fixé à la tige de réglage et coopérant avec le module d'activation de sorte qu'ils exercent l'un sur l'autre des contraintes mécaniques lorsque la seconde partie évolue entre les positions active et inactive, et de sorte que ces contraintes mécaniques soient libérées lorsque la seconde partie atteint l'une des positions active ou inactive.More specifically, the invention relates to a device for controlling a watch movement, characterized in that it comprises, on the one hand, a first part comprising a sliding guide tube intended to be fixed relative to said watch movement and an activation module, and on the other hand, a second movable part guided in sliding by the guide tube in a direction called the "axial direction", relative to said first part, between an active position in which it is capable of being secured, by means of an adjustment stem, to a component of the watch movement, and an inactive position in which said adjustment stem is intended to release the component of the watch movement, said second part comprising a slide fixed to the adjustment stem and cooperating with the activation module so that they exert mechanical stresses on each other when the second part moves between the active and inactive positions, and so that these mechanical stresses are released when the second part reaches one of the active or inactive positions.

Ce changement d'état contraint et non contraint lors du déplacement de la seconde partie provoque une sensation de retour tactile à l'utilisateur et plus précisément, une sensation d'indexation.This change of constrained and unconstrained state when moving the second part causes a tactile feedback sensation to the user and more precisely, a sensation of indexing.

Dans des modes particuliers de réalisation, l'invention peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises isolément ou selon toutes les combinaisons techniquement possibles.In particular embodiments, the invention may further comprise one or more of the following features, taken alone or in any technically possible combination.

Dans des modes particuliers de réalisation, le module d'activation exerce des contraintes mécaniques sur le coulisseau en réponse au déplacement dudit coulisseau lorsque la seconde partie évolue entre les positions active et inactive et libère les contraintes mécaniques lorsque la seconde partie atteint la position inactive.In particular embodiments, the activation module exerts mechanical constraints on the slider in response to movement of said slider when the second part moves between the active and inactive positions and releases the mechanical constraints when the second part reaches the inactive position.

Dans des modes particuliers de réalisation de l'invention, le module d'activation comporte un fourreau fixé au tube de guidage coopérant avec le coulisseau de sorte à le guider en translation sans degré de liberté en rotation, le module d'activation comprenant en outre un manchon relié cinématiquement avec le fourreau selon une liaison hélicoïdale et étant configuré, sous l'action d'un organe élastique à appliquer des contraintes mécaniques au coulisseau lorsque la seconde partie évolue entre les positions active et inactive.In particular embodiments of the invention, the activation module comprises a sheath fixed to the guide tube cooperating with the slider so as to guide it in translation without a degree of freedom in rotation, the activation module further comprising a sleeve kinematically connected to the sheath according to a helical connection and being configured, under the action of an elastic member, to apply mechanical stresses to the slider when the second part moves between the active and inactive positions.

Dans des modes particuliers de réalisation de l'invention, la fente du manchon débouche par une ouverture sur une extrémité dudit manchon et comporte, au niveau de cette ouverture, un profil de guidage formé par une augmentation de section de la fente, le profil de guidage étant configuré de sorte que lorsque la seconde partie se déplace depuis la position inactive vers la position active, la tige radiale exerce des efforts contre le profil de guidage entraînant un déplacement du manchon à l'encontre d'efforts exercés par l'organe élastique.In particular embodiments of the invention, the slot of the sleeve opens through an opening on one end of said sleeve and comprises, at this opening, a guide profile formed by an increase in the section of the slot, the guide profile being configured so that when the second part moves from the inactive position to the active position, the radial rod exerts forces against the guide profile causing the sleeve to move against forces exerted by the elastic member.

Dans des modes particuliers de réalisation de l'invention, le fourreau comporte une collerette radiale à l'une de ses extrémités dans le prolongement de la fente ladite collerette radiale étant ajourée de sorte à recevoir la tige radiale lorsque la seconde partie est en position inactive.In particular embodiments of the invention, the sheath comprises a radial collar at one of its ends in the extension of the slot, said radial collar being perforated so as to receive the radial rod when the second part is in the inactive position.

La collerette peut avantageusement constituer une butée contre laquelle s'appuie le manchon lorsque la seconde partie est en position inactive.The collar can advantageously constitute a stop against which the sleeve rests when the second part is in the inactive position.

Dans des modes particuliers de réalisation de l'invention, le fourreau et le tube de guidage définissent un volume annulaire dans lequel est agencé le manchon.In particular embodiments of the invention, the sheath and the guide tube define an annular volume in which the sleeve is arranged.

Dans des modes particuliers de réalisation de l'invention, le manchon comporte préférentiellement au moins un suiveur s'étendant radialement vers le fourreau ledit fourreau comportant au moins une lumière hélicoïdale agencée de sorte à recevoir ledit suiveur et constituant un chemin de coulissement dudit suiveur.In particular embodiments of the invention, the sleeve preferably comprises at least one follower extending radially towards the sheath, said sheath comprising at least one helical slot arranged so as to receive said follower and constituting a sliding path for said follower.

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 paroi périphérique est guidé en translation par une paroi périphérique d'une cavité borgne de la tête et comprenant une seconde portion cylindrique dont une paroi périphérique guidant en translation la tige de réglage le module d'activation étant logé dans le volume interne de la première portion cylindrique.In particular embodiments of the invention, the guide tube has the shape of a stepped cylinder, comprising a first cylindrical portion, a peripheral wall of which is guided in translation by a peripheral wall of a blind cavity of the head and comprising a second cylindrical portion, a peripheral wall of which guides the adjustment rod in translation, the activation module being housed in the internal volume of the first cylindrical portion.

Description détaillée de l'inventionDetailed description of the invention

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

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

Le dispositif de commande 10 est destiné à être engagé à travers une carrure d'un boitier (non représenté) 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 case middle of a case (not shown) of a timepiece, in particular 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 100 comprenant un tube de guidage 101 en coulissement destiné à être engagé fixement dans un orifice traversant s'étendant radialement dans la carrure. Autrement dit, le tube de guidage 101 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 100 comprising a sliding guide tube 101 intended to be fixedly engaged in a through-hole extending radially in the caseband. In other words, the guide tube 101 is intended to be fixed relative to the watch movement.

La première partie 100 comprend en outre un module d'activation 120, représenté en détail sur les figures 3 à 6, permettant la génération d'une sensation de retour tactile d'un utilisateur, tel que décrit plus loin en détail.The first part 100 further comprises an activation module 120, shown in detail in the Figures 3 to 6 , enabling the generation of a tactile feedback sensation from a user, as described in detail below.

Par ailleurs, le dispositif de commande 10 comporte une seconde partie 200, mobile, comprenant une tige de réglage 201 s'étendant à travers le tube de guidage 101. Ladite tige est fixée, à l'une de ses extrémités, par l'intermédiaire d'un coulisseau 202, à une tête 203 coiffant le tube de guidage 101.Furthermore, the control device 10 comprises a second, movable part 200, comprising an adjustment rod 201 extending through the guide tube 101. Said rod is fixed, at one of its ends, by means of a slide 202, to a head 203 covering the guide tube 101.

La tige de réglage 201 est engagée en coulissement selon une direction axiale à travers le tube de guidage 101, de sorte que la seconde partie 200 coulisse par rapport à la première partie 100 entre une position active, représentée sur la figure 2, dans laquelle la tige de réglage 201 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 201 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 201 is slidably engaged in an axial direction through the guide tube 101, such that the second part 200 slides relative to the first part 100 between an active position, shown in the figure 2 , in which the adjusting rod 201 is able to be secured to a component of the watch movement, and an inactive position, represented on the figure 1 , in which the adjustment rod 201 is capable of releasing the component of the watch movement, that is to say that it is not integral with the latter.

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 201 est solidaire du mouvement horloger, elle peut agir sur ce dernier.In this text, the term "solid" means that two parts are kinematically connected together so that one can transmit a movement or force to the other. In other words, when the adjustment rod 201 is solid with the watch movement, it can act on the latter.

Plus particulièrement, lorsque la seconde partie 200 occupe la position active, elle est rétractée, telle que visible sur la figure 2, et lorsque la seconde partie 200 occupe la position inactive, elle est déployée, telle que visible sur la figure 1.More particularly, when the second part 200 occupies the active position, it is retracted, as visible in the figure 2 , and when the second part 200 occupies the inactive position, it is deployed, as visible on the figure 1 .

Le changement de position de la seconde partie 200 est provoqué par un utilisateur par le déplacement de la tête 203 le long de la direction axiale. Plus particulièrement, dans l'exemple préféré de réalisation de l'invention, la seconde partie 200 est entraînée en position inactive par un organe élastique 208 décrit en détail dans la suite du texte, et est destinée à être entraînée en position active sur pression de l'utilisateur.The change of position of the second part 200 is caused by a user by the movement of the head 203 along the axial direction. More particularly, in the preferred embodiment of the invention, the second part 200 is driven into the inactive position by an elastic member 208 described in detail in the remainder of the text, and is intended to be driven into the active position upon pressure from the user.

Avantageusement, le coulisseau 202 coopère avec le module d'activation 120 de sorte qu'ils exercent l'un sur l'autre des contraintes mécaniques lorsque la seconde partie 200 évolue entre les positions active et inactive, et de sorte que ces contraintes mécaniques soient libérées lorsque la seconde partie 200 atteint l'une des positions active ou inactive, en particulier la position inactive dans l'exemple préféré de réalisation décrit dans le présent texte.Advantageously, the slider 202 cooperates with the activation module 120 so that they exert mechanical stresses on each other when the second part 200 moves between the active and inactive positions, and so that these mechanical stresses are released when the second part 200 reaches one of the active or inactive positions, in particular the inactive position in the preferred embodiment described in the present text.

Grâce à cette caractéristique, lorsque l'utilisateur presse la tête 203 de sorte à translater la seconde partie 200 jusqu'à sa position active, il va agir à l'encontre des efforts résultant des contraintes mécaniques que le coulisseau 202 et le module d'activation 120 exercent l'un contre l'autre. L'utilisateur ressent donc une résistance mécanique tout au long de la course de la seconde partie 200.Thanks to this feature, when the user presses the head 203 so as to translate the second part 200 to its active position, it will act against the forces resulting from the mechanical constraints that the slider 202 and the activation module 120 exert against each other. The user therefore feels mechanical resistance throughout the stroke of the second part 200.

Par ailleurs, lorsque l'utilisateur relâche la pression qu'il exerce sur la tête 203, ou tire ladite tête 203, selon la présence ou non d'un organe de retour élastique, de sorte à déplacer la seconde partie 200 vers la position inactive, il ressent une résistance tout au long de la course de la seconde partie 200, jusqu'à ce que ladite seconde partie 200 atteigne la position inactive, les contraintes mécaniques étant alors subitement libérées, l'utilisateur ressent un relâchement soudain de ces efforts.Furthermore, when the user releases the pressure that he exerts on the head 203, or pulls said head 203, depending on the presence or absence of an elastic return member, so as to move the second part 200 towards the inactive position, he feels a resistance throughout the travel of the second part 200, until said second part 200 reaches the inactive position, the mechanical constraints then being suddenly released, the user feels a sudden release of these forces.

Ainsi, le dispositif de commande 10 provoque chez l'utilisateur, lorsqu'il manipule la seconde partie 200 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 he manipulates the second part 200 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 à 6 est décrit plus en détail ci-après.A particular example of embodiment of the invention shown in the Figures 1 to 6 is described in more detail below.

Comme le montrent les figures 1 et 2, la tête 203 présente une cavité 204 borgne de forme sensiblement cylindrique de révolution, définie par une paroi de fond 205 et par une paroi périphérique 206.As shown in the Figures 1 and 2 , the head 203 has a blind cavity 204 of substantially cylindrical shape of revolution, defined by a bottom wall 205 and by a peripheral wall 206.

Le coulisseau 202 présente une forme cylindrique de révolution et relie la tête 203 et la tige de réglage 201 par chacune de ses extrémités. Avantageusement, le coulisseau 202 est logé dans la cavité 204 et est fixé contre la paroi de fond 205, par vissage et/ou collage, ou par tout autre moyen approprié.The slide 202 has a cylindrical shape of revolution and connects the head 203 and the adjustment rod 201 by each of its ends. Advantageously, the slide 202 is housed in the cavity 204 and is fixed against the bottom wall 205, by screwing and/or gluing, or by any other suitable means.

Le coulisseau 202 comporte des organes d'arrêt en rotation agencés pour coopérer avec des organes complémentaires d'arrêt en rotation du module d'activation 120 de sorte à interdire la rotation du coulisseau 202, notamment lors du déplacement de la seconde partie 200.The slider 202 comprises rotation stop members arranged to cooperate with complementary rotation stop members of the activation module 120 so as to prevent rotation of the slider 202, in particular during movement of the second part 200.

Dans l'exemple préféré de réalisation de l'invention représenté sur les figures 1 à 6, les organes d'arrêt en rotation sont formés par au moins une tige radiale 207, préférentiellement deux tiges radiales 207 diamétralement opposées.In the preferred embodiment of the invention shown in the Figures 1 to 6 , the rotation stop members are formed by at least one radial rod 207, preferably two diametrically opposed radial rods 207.

Le tube de guidage 101 présente préférentiellement deux portées de guidage en translation par rapport à la seconde partie 200.The guide tube 101 preferably has two guide surfaces in translation relative to the second part 200.

Plus particulièrement, dans l'exemple préféré de réalisation de l'invention représenté sur les figures 1 et 2, le tube de guidage 101 présente une forme de cylindre étagé comprenant une première portion cylindrique 102 et une seconde portion cylindrique 103. Comme visible sur les figures 1 et 2, la première portion cylindrique 102 présente un diamètre supérieur à la seconde portion cylindrique 103.More particularly, in the preferred embodiment of the invention shown in the Figures 1 and 2 , the guide tube 101 has a stepped cylinder shape comprising a first cylindrical portion 102 and a second cylindrical portion 103. As visible in the Figures 1 and 2 , the first cylindrical portion 102 has a diameter greater than the second cylindrical portion 103.

La première portion cylindrique 102 est engagée dans la cavité 204 de la tête 203, ladite première portion cylindrique 102 comportant une paroi périphérique dont la surface externe coopère en coulissement par ajustement glissant avec la surface interne de la paroi périphérique 206 de la tête 203. En particulier, la paroi périphérique peut comprendre une portée annulaire 104 prévue pour glisser contre la paroi périphérique 206 de la tête 203.The first cylindrical portion 102 is engaged in the cavity 204 of the head 203, said first cylindrical portion 102 comprising a peripheral wall whose external surface cooperates in sliding by sliding fit with the internal surface of the peripheral wall 206 of the head 203. In particular, the peripheral wall may comprise an annular bearing surface 104 intended to slide against the peripheral wall 206 of the head 203.

La première portion cylindrique 102 comprend une paroi de fond 105 par laquelle elle est reliée à la seconde portion cylindrique 103. Ladite paroi de fond 105 forme un épaulement et définit, avec la paroi périphérique de la première portion cylindrique 102, un volume interne.The first cylindrical portion 102 comprises a bottom wall 105 by which it is connected to the second cylindrical portion 103. Said bottom wall 105 forms a shoulder and defines, with the peripheral wall of the first cylindrical portion 102, an internal volume.

Dans cet exemple de réalisation, tel qu'illustré sur les figures 1 à 6, le module d'activation 120 est logé dans le volume interne de la première portion cylindrique 102.In this exemplary embodiment, as illustrated in the Figures 1 to 6 , the activation module 120 is housed in the internal volume of the first cylindrical portion 102.

Le module d'activation 120 comporte un fourreau 121 présentant une forme cylindrique de révolution, fixé de façon concentrique au tube de guidage 101. Le fourreau 121 comporte une paroi périphérique 122 sur laquelle sont agencés des organes complémentaires d'arrêt en rotation coopérant avec ceux du coulisseau 202. Ces organes complémentaires d'arrêt en rotation sont, dans l'exemple de réalisation représenté sur les figures 1 à 6, sous la forme d'au moins une fente 123, préférentiellement deux fentes, s'étendant axialement de sorte à guider les tiges radiales 207 en coulissement lors du déplacement de la seconde partie 200 entre les positions active et inactive.The activation module 120 comprises a sheath 121 having a cylindrical shape of revolution, fixed concentrically to the guide tube 101. The sheath 121 comprises a peripheral wall 122 on which are arranged complementary rotation stop members cooperating with those of the slide 202. These complementary members rotation stop are, in the embodiment shown in the Figures 1 to 6 , in the form of at least one slot 123, preferably two slots, extending axially so as to guide the radial rods 207 in sliding during the movement of the second part 200 between the active and inactive positions.

Plus particulièrement, les tiges radiales 207 s'étendent à travers et au-delà des fentes 123.More particularly, the radial rods 207 extend through and beyond the slots 123.

Dans l'exemple de réalisation préféré, les fentes 123 sont diamétralement opposées l'une de l'autre et débouchent sur une extrémité du fourreau 121 orientée vers la tête 203, ladite extrémité étant appelée « extrémité distale » dans la suite du texte.In the preferred embodiment, the slots 123 are diametrically opposite one another and open onto one end of the sheath 121 oriented towards the head 203, said end being called “distal end” in the remainder of the text.

Les termes « distal » et « proximal » sont relatifs dans le présent texte à l'éloignement vis-à-vis du mouvement horloger.The terms “distal” and “proximal” relate in this text to the distance from the watch movement.

L'extrémité distale est opposée à une extrémité proximale fixée au tube de guidage 101, plus particulièrement à la paroi de fond 105.The distal end is opposite a proximal end fixed to the guide tube 101, more particularly to the bottom wall 105.

Le fourreau 121 comprend une collerette radiale 124 à son extrémité distale formant un épaulement. La collerette radiale 124 est ajourée radialement, dans le prolongement des fentes 123, de sorte à recevoir les tiges radiales 207 lorsque la seconde partie 200 est en position inactive, comme le montrent les figures 1 et 3.The sheath 121 comprises a radial collar 124 at its distal end forming a shoulder. The radial collar 124 is perforated radially, in the extension of the slots 123, so as to receive the radial rods 207 when the second part 200 is in the inactive position, as shown in the figures 1 And 3 .

La collerette radiale 124, la paroi de fond 105, et les parois périphériques respectives de la première portion cylindrique 102 et du fourreau 121 définissent un volume annulaire dans lequel est agencé un manchon 125.The radial collar 124, the bottom wall 105, and the respective peripheral walls of the first cylindrical portion 102 and the sheath 121 define an annular volume in which a sleeve 125 is arranged.

Le manchon 125 est relié cinématiquement avec le fourreau 121 selon une liaison hélicoïdale. Plus spécifiquement, comme le montrent les vues éclatées des figures 4 et 6, le manchon 125 comporte préférentiellement au moins un suiveur 126 sous la forme d'un téton, s'étendant radialement vers le fourreau 121. Par ailleurs, le fourreau 121 comporte au moins une lumière hélicoïdale 127 agencée dans sa paroi périphérique de sorte à recevoir le suiveur 126, et constituant un chemin de coulissement dudit suiveur 126.The sleeve 125 is kinematically connected to the sheath 121 by a helical connection. More specifically, as shown in the exploded views of the Figures 4 and 6 , the sleeve 125 preferably comprises at least one follower 126 in the form of a nipple, extending radially towards the sheath 121. Furthermore, the sheath 121 comprises at least one helical light 127 arranged in its peripheral wall so as to receive the follower 126, and constituting a sliding path for said follower 126.

Préférentiellement, le manchon 125 comporte deux suiveurs 126 diamétralement opposés, engagés respectivement dans deux lumières hélicoïdales 127 du fourreau 121.Preferably, the sleeve 125 comprises two diametrically opposed followers 126, engaged respectively in two helical slots 127 of the sheath 121.

Les deux lumières hélicoïdales 127 sont symétriques l'une de l'autre selon un axe de révolution du fourreau 121.The two helical lights 127 are symmetrical to each other along an axis of revolution of the sheath 121.

Le manchon 125 comporte en outre, comme le montrent les figures 1 à 6, au moins une fente 128 s'étendant axialement, destinée à recevoir une tige radiales 207. Ladite au moins une fente 128 débouche par une ouverture sur une extrémité du manchon 125, dite « extrémité distale », en vis-à-vis de la collerette radiale 124.The sleeve 125 further comprises, as shown in the Figures 1 to 6 , at least one slot 128 extending axially, intended to receive a radial rod 207. Said at least one slot 128 opens through an opening on one end of the sleeve 125, called the “distal end”, opposite the radial collar 124.

Préférentiellement, le manchon 125 comporte deux fentes 128 diamétralement opposées, lesdites fentes 128 comportant, au niveau de l'ouverture, un profil de guidage 129 formé par un pan incliné ou un congé. Comme l'illustrent les figures 3 à 6, le profil de guidage 129 permet d'évaser lesdites fentes 128.Preferably, the sleeve 125 comprises two diametrically opposed slots 128, said slots 128 comprising, at the opening, a guide profile 129 formed by an inclined face or a fillet. As illustrated in Figures 3 to 6 , the guide profile 129 makes it possible to flare said slots 128.

Avantageusement, le manchon 125 est soumis à un effort élastique généré par un organe élastique 130 tendant à déplacer ledit manchon 125 vers la collerette radiale 124. Autrement dit, l'organe élastique 130 tend à déplacer le manchon 125 vers l'extrémité distale du fourreau 121. Par voie de conséquence, l'effort élastique tend également à pivoter le manchon 125, du fait de la liaison hélicoïdale, de sorte que la fente 128 soit angulairement décalée par rapport à celle du fourreau 121, c'est-à-dire de sorte que les deux fentes ne soient pas en vis-à-vis l'une de l'autre.Advantageously, the sleeve 125 is subjected to an elastic force generated by an elastic member 130 tending to move said sleeve 125 towards the radial collar 124. In other words, the elastic member 130 tends to move the sleeve 125 towards the distal end of the sheath 121. Consequently, the elastic force also tends to pivot the sleeve 125, due to the helical connection, so that the slot 128 is angularly offset relative to that of the sheath 121, that is to say so that the two slots are not opposite each other.

L'organe élastique 130 est agencé en appui contre la paroi de fond 105 du tube de guidage 101 et contre une extrémité proximale du manchon 125, opposée à l'extrémité distale dudit manchon 125. L'organe élastique 130 travaille en compression et est préférentiellement formé par un ressort hélicoïdal.The elastic member 130 is arranged to bear against the bottom wall 105 of the guide tube 101 and against a proximal end of the sleeve 125, opposite the distal end of said sleeve 125. The elastic member 130 works in compression and is preferably formed by a helical spring.

Grâce à ces caractéristiques, lorsque la seconde partie 200 est entraînée depuis la position inactive vers la position active, les tiges radiales 207 se déplacent depuis l'extrémité distale du fourreau 121, le long de la fente 123 dudit fourreau 121, et dans le même temps, contre le profil de guidage 129 du manchon 125, qui les entraîne progressivement dans les fentes 128 dudit manchon 125, de sorte que les tiges coulissent le long desdites fentes 128.By virtue of these features, when the second part 200 is driven from the inactive position to the active position, the radial rods 207 move from the distal end of the sheath 121, along the slot 123 of said sheath 121, and at the same time, against the guide profile 129 of the sleeve 125, which gradually drives them into the slots 128 of said sleeve 125, so that the rods slide along said slots 128.

Le déplacement des tiges radiales 207 contre le profil de guidage 129 entraîne un pivotement du manchon 125, comme le montrent en particulier les figures 3 et 5, et donc un déplacement des suiveurs 126 au sein des lumières hélicoïdales 127, et par voie de conséquence, une translation du manchon 125 à l'encontre de la force élastique générée par l'organe élastique 130.The movement of the radial rods 207 against the guide profile 129 causes the sleeve 125 to pivot, as shown in particular by the Figures 3 and 5 , and therefore a movement of the followers 126 within the helical slots 127, and consequently, a translation of the sleeve 125 against the elastic force generated by the elastic member 130.

La force élastique est ainsi à l'origine d'efforts générés par le manchon 125 sur les coulisseaux 202 ; ces derniers étant engagés dans les fentes 123 du fourreau 121, ils génèrent des efforts antagonistes à ceux générés par le manchon 125. Ainsi, le coulisseau 202 et le module d'activation 120 exercent l'un contre l'autre des contraintes mécaniques réciproques tendant à freiner la course de la seconde partie 200 entre ses positions active et inactive.The elastic force is thus at the origin of forces generated by the sleeve 125 on the slides 202; the latter being engaged in the slots 123 of the sheath 121, they generate forces antagonistic to those generated by the sleeve 125. Thus, the slide 202 and the activation module 120 exert against each other reciprocal mechanical stresses tending to slow the travel of the second part 200 between its active and inactive positions.

Autrement dit, le but de la liaison hélicoïdale entre le manchon 125 et le fourreau 121 est de transformer l'effort linéaire de la force élastique en effort de torsion tendant à freiner la course de la seconde partie 200 entre ses positions active et inactive.In other words, the purpose of the helical connection between the sleeve 125 and the sheath 121 is to transform the linear force of the elastic force into a torsional force tending to slow the travel of the second part 200 between its active and inactive positions.

Par ailleurs, lorsque la seconde partie 200 est entraînée depuis la position active vers la position inactive, les tiges radiales 207 se déplacent, à travers les fentes 123 et 128 respectives du fourreau 121 et du manchon 125, vers leur extrémité distale respective. Ceci jusqu'à atteindre le profil de guidage 129, contre lequel elles sont entraînées en appui par la rotation du manchon 125 provoquée par la liaison hélicoïdale entre le fourreau 121 et ledit manchon 125, sous l'action de la force élastique.Furthermore, when the second part 200 is driven from the active position to the inactive position, the radial rods 207 move, through the respective slots 123 and 128 of the sheath 121 and the sleeve 125, towards their respective distal end. This until reaching the profile of guide 129, against which they are driven in support by the rotation of the sleeve 125 caused by the helical connection between the sheath 121 and said sleeve 125, under the action of the elastic force.

La seconde partie 200 est entraînée en translation dans la position inactive par un organe élastique 208 constitué, dans l'exemple représenté sur les figures, par un ressort de compression.The second part 200 is driven in translation into the inactive position by an elastic member 208 constituted, in the example shown in the figures, by a compression spring.

A cet effet, la tige de réglage 201 comporte une butée distale, formée dans l'exemple préféré de réalisation de l'invention, par un épaulement radial résultant d'une réduction de section. Grâce à cette réduction de section, un volume annulaire est formé entre la tige de réglage 201 et le fourreau 121, permettant l'agencement du ressort de compression.For this purpose, the adjustment rod 201 comprises a distal stop, formed in the preferred embodiment of the invention, by a radial shoulder resulting from a reduction in section. Thanks to this reduction in section, an annular volume is formed between the adjustment rod 201 and the sheath 121, allowing the arrangement of the compression spring.

Plus particulièrement, le ressort de compression est agencé en appui contre la paroi de fond 105 et contre l'épaulement radial, de sorte à générer une force tendant à éloigner la tête 203 et le coulisseau 202 du tube de guidage 101.More particularly, the compression spring is arranged to bear against the bottom wall 105 and against the radial shoulder, so as to generate a force tending to move the head 203 and the slide 202 away from the guide tube 101.

La tige de réglage 201 comporte une butée proximale, formée dans l'exemple préféré de réalisation de l'invention par un anneau élastique 209 logé dans une gorge annulaire s'étendant radialement dans ladite tige de réglage 201.The adjustment rod 201 comprises a proximal stop, formed in the preferred embodiment of the invention by an elastic ring 209 housed in an annular groove extending radially in said adjustment rod 201.

Le tube de guidage 101 est en appui contre l'anneau élastique 209 lorsque la seconde partie 200 occupe la position inactive, comme le montre la figure 1.The guide tube 101 bears against the elastic ring 209 when the second part 200 occupies the inactive position, as shown in figure 1 .

Ainsi, lorsque l'utilisateur relâche la pression exercée sur la tête 203, la seconde partie 200 est entraînée vers la position inactive par l'organe élastique 208. L'utilisateur accompagnant la seconde partie 200 dans son déplacement jusqu'à la position inactive, il ressent le relâchement des contraintes mécaniques exercées entre le manchon 125 et le coulisseau 202 en fin de course, et par conséquent, il ressent une sensation de retour tactile lui indiquant que la seconde partie 200 a atteint la position inactive.Thus, when the user releases the pressure exerted on the head 203, the second part 200 is driven towards the inactive position by the elastic member 208. The user accompanying the second part 200 in its movement to the inactive position, he feels the release of the mechanical constraints exerted between the sleeve 125 and the slider 202 at the end of the stroke, and consequently, he feels a tactile feedback sensation indicating to him that the second part 200 has reached the inactive position.

La seconde portion cylindrique 103 du tube de guidage 101 est emmanchée autour de la tige de réglage 201, ladite seconde portion cylindrique 103 comportant une paroi périphérique 116 dont la surface interne coopère en coulissement par ajustement glissant avec ladite tige de réglage 201.The second cylindrical portion 103 of the guide tube 101 is fitted around the adjustment rod 201, said second cylindrical portion 103 comprising a peripheral wall 116 whose internal surface cooperates in sliding by sliding adjustment with said adjustment rod 201.

En outre, la seconde portion cylindrique 103 comporte un chambrage 131 recevant des joints d'étanchéité interposés entre la paroi périphérique de la seconde portion cylindrique 103 et la tige de réglage 201.Furthermore, the second cylindrical portion 103 comprises a recess 131 receiving sealing gaskets interposed between the peripheral wall of the second cylindrical portion 103 and the adjustment rod 201.

Enfin, la seconde portion cylindrique 103 comprend une extrémité libre opposée à la première portion cylindrique 102, prévue pour venir en appui contre la butée distale de la tige de réglage 201 lorsque la seconde partie 200 occupe la position inactive.Finally, the second cylindrical portion 103 comprises a free end opposite the first cylindrical portion 102, intended to come to bear against the distal stop of the adjustment rod 201 when the second part 200 occupies the inactive position.
