La demande de brevet CH640686 divulgue un mécanisme comprenant une tige de commande susceptible d'être positionnée selon deux positions axiales. Pour ce faire, un bec formé à une extrémité d'un ressort de tirette coopère avec un tenon solidaire d'une tirette. Plus particulièrement, un premier flanc du bec du ressort de tirette est en appui à l'encontre du tenon de tirette de sorte à définir une première position axiale de tige, tandis qu'un deuxième flanc du bec est susceptible de venir en appui à l'encontre de ce même tenon de tirette sous l'effet d'une traction de la tige, de sorte à définir une deuxième position axiale de tige. Dans ce mécanisme, le ressort de tirette est venu de matière avec une bascule de mécanisme, et le bec est venu de matière avec le ressort de tirette.The patent application CH640686 discloses a mechanism comprising a control rod capable of being positioned in two axial positions. To do this, a beak formed at one end of a pull spring cooperates with a tenon secured to a pull. More particularly, a first flank of the beak of the pull spring bears against the pull tenon so as to define a first axial rod position, while a second flank of the beak is capable of coming to bear against this same pull tenon under the effect of a pull of the rod, so as to define a second axial rod position. In this mechanism, the pull spring is integral with a mechanism rocker, and the beak is integral with the pull spring.

La demande de brevet WO2012175595 divulgue un mécanisme comprenant une tige de commande susceptible d'être positionnée selon trois positions axiales. Pour ce faire, un bec formé à une extrémité d'un ressort de tirette coopère avec un tenon d'une tirette. Le bec présente ici la particularité de comprendre un creux intercalé entre deux flancs de bec définissant les positions extrémales de la tige, de sorte à définir une position intermédiaire de tige. À l'instar du ressort de tirette du mécanisme du document CH640686 , le bec est également venu de matière du ressort de tirette.The patent application WO2012175595 discloses a mechanism comprising a control rod capable of being positioned in three axial positions. To do this, a beak formed at one end of a pull spring cooperates with a tenon of a pull. The beak here has the particularity of comprising a hollow interposed between two beak flanks defining the extreme positions of the rod, so as to define an intermediate rod position. Like the pull spring of the mechanism of the document CH640686 , the spout also came from the material of the pull spring.

La demande de brevet CH713526 divulgue un mécanisme comprenant un dispositif alternatif de tirette. Dans un premier mode de réalisation du dispositif de tirette, le ressort de tirette se présente sous la forme d'un composant monobloc. Il comprend un ressort-lame, ainsi qu'un bec pivoté en rotation à l'encontre d'un flanc cranté d'une tirette sous l'effet dudit ressort-lame. Dans des modes de réalisation alternatifs du dispositif de tirette, le bec se présente sous la forme d'un composant à part entière articulé sur un bâti d'un mouvement, qui est intercalé entre un ressort de tirette et une tirette.The patent application CH713526 discloses a mechanism comprising an alternative pull-tab device. In a first embodiment of the pull-tab device, the pull-tab spring is in the form of a single-piece component. It comprises a leaf spring, as well as a beak pivoted in rotation against a notched flank of a pull-tab under the effect of said leaf spring. In alternative embodiments of the pull-tab device, the beak is in the form of a separate component articulated on a frame of a movement, which is interposed between a pull-tab spring and a pull-tab.

Enfin, le document CH599594 fait état d'un mécanisme comprenant une tige de commande susceptible de présenter deux ou trois positions axiales selon la configuration d'un dispositif de tirette formé d'un ressort de tirette comprenant un bec et d'une tirette comprenant un tenon. Dans une première configuration du bec du ressort de tirette en regard du tenon de tirette, la face arrière du bec, formée de deux flancs distincts, est en appui à l'encontre du tenon de tirette, si bien que le dispositif de tirette permet de définir deux positions axiales pour la tige de commande. Dans une deuxième configuration du bec de tirette en regard du tenon de tirette, la face avant du bec, formée d'un premier flanc, d'un creux, et d'un deuxième flanc, est en appui à l'encontre du tenon de tirette, si bien que le dispositif de tirette permet de définir trois positions axiales pour la tige de commande. Le bec est ici venu de matière du ressort de tirette. Un tel mécanisme a pour avantage de rationaliser le nombre de composants dans la définition d'un mécanisme à deux ou trois positions. Néanmoins, le ressort de tirette est précontraint de deux manières différentes en fonction de la configuration du bec du ressort de tirette à l'encontre du tenon de tirette, si bien que les forces produites à la tige peuvent différer.Finally, the document CH599594 discloses a mechanism comprising a control rod capable of having two or three axial positions depending on the configuration of a pull device formed by a pull spring comprising a beak and a pull comprising a tenon. In a first configuration of the beak of the pull spring opposite the pull tenon, the rear face of the beak, formed by two separate flanks, bears against the pull tenon, such that the pull device makes it possible to define two axial positions for the control rod. In a second configuration of the pull beak opposite the pull tenon, the front face of the beak, formed by a first flank, a hollow, and a second flank, bears against the pull tenon, such that the pull device makes it possible to define three axial positions for the control rod. The beak is here made from the material of the pull spring. Such a mechanism has the advantage of rationalizing the number of components in the definition of a two or three position mechanism. However, the pull spring is preloaded in two different ways depending on the configuration of the pull spring beak against the pull tenon, so that the forces produced at the rod may differ.

Par ailleurs, il est possible qu'un horloger puisse faire une erreur d'assemblage lors de l'assemblage du mouvement auquel le mécanisme prend part ou lors d'une opération de rhabillage.Furthermore, it is possible that a watchmaker may make an assembly error when assembling the movement in which the mechanism takes part or during a re-assembly operation.

Le but de l'invention est de fournir un dispositif d'indexation de tirette permettant d'améliorer les dispositifs connus de l'art antérieur. En particulier, l'invention propose un dispositif d'indexation de tirette simple et fiable qui permet de définir différentes configurations d'indexation.The aim of the invention is to provide a pull tab indexing device that makes it possible to improve the devices known from the prior art. In particular, the invention provides a simple and reliable pull tab indexing device that makes it possible to define different indexing configurations.

Un premier mode de réalisation d'une pièce d'horlogerie 1000 est décrit ci-après en référence aux figures 1 à 9.A first embodiment of a timepiece 1000 is described below with reference to the Figures 1 to 9 .

La pièce d'horlogerie 1000 est par exemple une montre, en particulier une montre bracelet.The timepiece 1000 is for example a watch, in particular a wristwatch.

La pièce d'horlogerie 1000 comprend un mouvement horloger 700 destiné à être monté dans une boîte de pièce d'horlogerie afin de le protéger de l'environnement extérieur.The 1000 timepiece includes a 700 watch movement intended to be mounted in a timepiece case in order to protect it from the external environment.

Le mouvement horloger 700 peut être un mouvement électronique ou un mouvement mécanique, notamment un mouvement automatique.The 700 watch movement can be an electronic movement or a mechanical movement, especially an automatic movement.

Le mouvement horloger 700 comprend un mécanisme horloger 600. Notamment, le mécanisme horloger peut être un mécanisme mettant en oeuvre un dispositif de tirette. Le mécanisme horloger comprend un dispositif d'indexation 100 de tirette et un bâti 99 comprenant une ébauche. Par « indexation d'une tirette », on entend la définition de différentes positions stables de la tirette. Ces positions stables sont séparées par un continuum de positions intermédiaires instables. L'utilisateur fait passer, par une action mécanique, notamment une action mécanique sur une tige, la tirette d'une position stable à une autre, via un continuum de positions intermédiaires instables. Entre deux positions stables ou deux positions indexées ou deux positions d'indexations, la tirette passe transitoirement par un continuum de positions intermédiaires instables.The watch movement 700 comprises a watch mechanism 600. In particular, the watch mechanism may be a mechanism implementing a pull device. The watch mechanism comprises a pull indexing device 100 and a frame 99 comprising a blank. By "indexing a pull", we mean the definition of different stable positions of the pull. These stable positions are separated by a continuum of unstable intermediate positions. The user, by a mechanical action, in particular a mechanical action on a stem, moves the pull from one stable position to another, via a continuum of unstable intermediate positions. Between two stable positions or two indexed positions or two indexing positions, the pull transitorily passes through a continuum of unstable intermediate positions.

Le dispositif d'indexation 100 peut notamment comprendre un dispositif de levier pour tirette ou un dispositif de levier-ressort pour tirette. Dans le premier mode de réalisation, le dispositif d'indexation comprend un dispositif de levier-ressort 2 pour tirette 10.The indexing device 100 may in particular comprise a lever device for a pull tab or a spring lever device for a pull tab. In the first embodiment, the indexing device comprises a spring lever device 2 for a pull tab 10.

La tirette 10 est engagée, notamment par l'une de ses extrémités, dans une rainure d'une première tige 5 de commande. La tirette, notamment via une autre extrémité, commande une bascule 6 engagée dans une rainure d'un pignon coulant 7. La tirette 10 permet ainsi de piloter, au moins indirectement, la position du pignon coulant. La position de la tirette est indexée par un dispositif d'indexation prévu à cet effet.The pull rod 10 is engaged, in particular by one of its ends, in a groove of a first control rod 5. The pull rod, in particular via another end, controls a lever 6 engaged in a groove of a sliding pinion 7. The pull rod 10 thus makes it possible to control, at least indirectly, the position of the sliding pinion. The position of the pull rod is indexed by an indexing device provided for this purpose.

La tirette 10 est pivotée sur le bâti 99 selon un axe A1. Le mécanisme 600 comprend aussi un ressort 97 plaquant la tirette 10 à l'encontre du bâti, notamment à l'encontre d'une ébauche 99 du mécanisme 600.The pull tab 10 is pivoted on the frame 99 along an axis A1. The mechanism 600 also comprises a spring 97 pressing the pull tab 10 against the frame, in particular against a blank 99 of the mechanism 600.

La tige 5 de commande fait partie du mécanisme 600. La tige 5 de commande est mobile en translation dans un plan P perpendiculaire ou sensiblement perpendiculaire à l'axe A1 de tirette, selon une direction D. Cette tige 5 coopère classiquement avec la tirette 10 par le biais d'un plot 11 de tirette engagé dans une gorge 51 de la tige 5. Ainsi, un mouvement de translation de la tige 5 dans le plan P, selon la direction D, induit un mouvement de rotation de la tirette 10 autour de l'axe A1.The control rod 5 is part of the mechanism 600. The control rod 5 is movable in translation in a plane P perpendicular or substantially perpendicular to the pull rod axis A1, in a direction D. This rod 5 conventionally cooperates with the pull rod 10 by means of a pull rod stud 11 engaged in a groove 51 of the rod 5. Thus, a translational movement of the rod 5 in the plane P, in the direction D, induces a rotational movement of the pull rod 10 around the axis A1.

Le mécanisme 600 comprend aussi un dispositif de levier-ressort 2 de tirette. La tirette 10 est également prévue pour coopérer avec le dispositif de levier-ressort 2 pour constituer le dispositif d'indexation 100 de tirette, afin que ce dernier puisse définir des positions axiales de la tige 5. Autrement dit, le dispositif d'indexation comprend aussi la tirette.The mechanism 600 also comprises a lever-spring device 2 of the pull rod. The pull rod 10 is also provided to cooperate with the lever-spring device 2 to constitute the pull rod indexing device 100, so that the latter can define axial positions of the rod 5. In other words, the indexing device also comprises the pull rod.

Par « position axiale » de la tige 5 ou du pignon coulant 7, nous entendons une position particulière, selon l'axe D, de la tige 5 ou du pignon coulant 7 en regard du mouvement 700, suite à un déplacement de la tige 5 selon la direction D dans le plan P.By “axial position” of the rod 5 or the sliding pinion 7, we mean a particular position, along the axis D, of the rod 5 or the sliding pinion 7 with respect to the movement 700, following a movement of the rod 5 along the direction D in the plane P.

La tirette 10 est également prévue pour coopérer avec la bascule 6 de mécanisme pivotée selon un axe A6 et rappelée élastiquement par un ressort 98, de sorte à piloter la position axiale du pignon coulant 7. Le pignon coulant est par exemple agencé sur une deuxième tige 8. La deuxième tige 8 est par exemple parallèle ou sensiblement parallèle à la première tige 5. Pour ce faire, la bascule 6 est engagée dans une gorge 71 du pignon 7. Ce pignon 7 comprend également des première et deuxième dentures 72, 73, qui sont susceptibles de venir en prise avec une chaîne de réglage particulière du mécanisme 600 en fonction de la position axiale de la première tige 5.The pull rod 10 is also designed to cooperate with the mechanism rocker 6 pivoted along an axis A6 and elastically returned by a spring 98, so as to control the axial position of the sliding pinion 7. The sliding pinion is for example arranged on a second rod 8. The second rod 8 is for example parallel or substantially parallel to the first rod 5. To do this, the rocker 6 is engaged in a groove 71 of the pinion 7. This pinion 7 also comprises first and second teeth 72, 73, which are capable of engaging with a particular adjustment chain of the mechanism 600 depending on the axial position of the first rod 5.

La cinématique du pignon coulant 7 est comparable à celle du pignon coulant du mécanisme décrit dans la demande de brevet WO2012175595 :

  • Dans une première position axiale P1 de la première tige 5 et/ou du pignon coulant 7, les dentures 72, 73 sont hors de portée des roues prenant part aux différentes chaînes de réglage du mécanisme.
  • Dans une éventuelle position intermédiaire P2 de la première tige 5 et/ou du pignon coulant 7, la denture de chant 72 du pignon coulant 7 est en prise avec une denture d'une roue 20 d'une première chaîne 200 de réglage d'une indication horaire ou dérivée de l'heure, en particulier une indication calendaire telle qu'une indication des quantièmes.
  • Dans une troisième position P3 de la première tige 5 et/ou du pignon coulant 7, la denture frontale 73 du pignon coulant 7 est en prise avec une denture d'un pignon 30 d'une deuxième chaîne 300 de réglage d'une indication horaire ou dérivée de l'heure, en particulier de mise à l'heure du mouvement 700.
The kinematics of the sliding pinion 7 are comparable to those of the sliding pinion of the mechanism described in the patent application. WO2012175595 :
  • In a first axial position P1 of the first rod 5 and/or of the sliding pinion 7, the teeth 72, 73 are out of reach of the wheels taking part in the different adjustment chains of the mechanism.
  • In a possible intermediate position P2 of the first rod 5 and/or of the sliding pinion 7, the edge teeth 72 of the sliding pinion 7 are engaged with a toothing of a wheel 20 of a first chain 200 for adjusting a time indication or a time-derived indication, in particular a calendar indication such as a date indication.
  • In a third position P3 of the first rod 5 and/or of the sliding pinion 7, the front toothing 73 of the sliding pinion 7 is engaged with a toothing of a pinion 30 of a second chain 300 for adjusting a time indication or a time-derived indication, in particular for setting the time of the movement 700.

Par ailleurs, le pignon coulant 7 est ici susceptible d'être entraîné en rotation sous l'actionnement en rotation de la première tige 5 par l'intermédiaire d'un pignon 9 monté à carré sur la première tige 5, qui est en prise avec la denture de chant 72 du pignon coulant 7. Ainsi, le pignon coulant 7 est relié cinématiquement à la première tige 5, que ce soit en translation selon la direction D par l'intermédiaire de la tirette 10, de la bascule 6 et de son ressort de rappel 98, ou bien en rotation par l'intermédiaire du pignon 9.Furthermore, the sliding pinion 7 is here capable of being driven in rotation under the rotational actuation of the first rod 5 by means of a pinion 9 mounted square on the first rod 5, which is engaged with the edge teeth 72 of the sliding pinion 7. Thus, the sliding pinion 7 is kinematically connected to the first rod 5, whether in translation in the direction D by means of the pull rod 10, the rocker 6 and its return spring 98, or in rotation by means of the pinion 9.

Le mécanisme 600 comprend également une chaîne cinématique 500 de remontage du mouvement 700. Celle-ci comprend un pignon 55 monté à carré sur la première tige 5, qui est en prise avec une première roue 56 de couronne. Cette première roue 56 de couronne est susceptible de venir en prise avec une deuxième roue 57 de couronne en fonction de l'état d'un dispositif d'embrayage vertical commandé par le déplacement de la première tige 5 selon la direction D.The mechanism 600 also comprises a kinematic chain 500 for winding the movement 700. This comprises a pinion 55 mounted square on the first rod 5, which is engaged with a first crown wheel 56. This first crown wheel 56 is capable of engaging with a second crown wheel 57 depending on the state of a vertical clutch device controlled by the movement of the first rod 5 in the direction D.

Ce dispositif d'embrayage est comparable à celui décrit au sein de la demande de brevet WO2012175595 . En particulier, il comprend une troisième tige 58 disposée perpendiculairement à la première tige 5 ou sensiblement perpendiculairement à la première tige 5, qui est solidaire d'une deuxième roue 57 de couronne. La première tige 5 pilote la troisième tige 58 par le biais d'une gorge 52 usinée en son sein. Dans la première position axiale P1 de la première tige 5, une extrémité de la troisième tige 58 se situe dans le fond de la gorge 52 de la première tige 5, si bien qu'une denture Breguet de la deuxième roue 57 de couronne est en prise avec une denture Breguet de la première roue 56 de couronne sous l'effet d'un ressort 96 de rappel. Ainsi, dans le première position axiale P1 de la première tige 5, la chaîne cinématique de remontage du mouvement 700 est embrayée. Un déplacement de la tige 5 vers l'extérieur du mouvement 700, depuis la position P1 et selon la direction D, induit le soulèvement de la troisième tige 58 depuis le fond de la gorge 52 de la première tige 5, si bien que la denture Breguet de la deuxième roue 57 de couronne est hors de portée de la denture Breguet de la première roue 56 de couronne. Ainsi, dans les positions P2, P3 de la première tige 5, la chaîne cinématique de remontage du mouvement 700 est débrayée.This clutch device is comparable to that described in the patent application. WO2012175595 . In particular, it comprises a third rod 58 arranged perpendicular to the first rod 5 or substantially perpendicular to the first rod 5, which is integral with a second crown wheel 57. The first rod 5 controls the third rod 58 by means of a groove 52 machined therein. In the first axial position P1 of the first rod 5, one end of the third rod 58 is located in the bottom of the groove 52 of the first rod 5, so that a Breguet toothing of the second crown wheel 57 is engaged with a Breguet toothing of the first crown wheel 56 under the effect of a return spring 96. Thus, in the first axial position P1 of the first rod 5, the kinematic chain for winding the movement 700 is engaged. A movement of the stem 5 towards the outside of the movement 700, from the position P1 and in the direction D, induces the lifting of the third stem 58 from the bottom of the groove 52 of the first stem 5, so that the Breguet toothing of the second crown wheel 57 is out of range of the Breguet toothing of the first crown wheel 56. Thus, in positions P2, P3 of the first rod 5, the winding kinematic chain of the movement 700 is disengaged.

Le dispositif d'indexation 100, en particulier le dispositif de levier-ressort 2, comprend :

  • un corps d'indexation 4, et
  • un élément d'indexation 3 comprenant au moins deux jeux de flancs 31a, 31b, 31c; 32a, 32b de définition de positions d'indexation de tirette et monté sur le corps d'indexation 4.
The indexing device 100, in particular the spring lever device 2, comprises:
  • an indexing body 4, and
  • an indexing element 3 comprising at least two sets of flanks 31a, 31b, 31c; 32a, 32b for defining pull tab indexing positions and mounted on the indexing body 4.

Le corps d'indexation 4 et l'élément d'indexation 3 sont agencés ou configurés de sorte à définir au moins deux positions de fixation, de l'élément d'indexation 3 sur le corps d'indexation 4. En effet, l'élément d'indexation peut être monté sur le corps d'indexation :

  • dans une première configuration ou position pour définir, une fois que le dispositif d'indexation est intégré au mécanisme 600, un premier ensemble de positions indexées de la tirette correspondant à un premier ensemble de positions indexées de la tige et/ou à un premier ensemble de positions indexées de la bascule, ou
  • dans une deuxième configuration ou position pour définir, une fois que le dispositif d'indexation est intégré au mécanisme 600, un deuxième ensemble de positions indexées de la tirette correspondant à un deuxième ensemble de positions indexées de la tige et/ou à un deuxième ensemble de positions indexées de la bascule.
The indexing body 4 and the indexing element 3 are arranged or configured so as to define at least two fixing positions of the indexing element 3 on the indexing body 4. Indeed, the indexing element can be mounted on the indexing body:
  • in a first configuration or position to define, once the indexing device is integrated into the mechanism 600, a first set of indexed positions of the pull corresponding to a first set of indexed positions of the rod and/or to a first set of indexed positions of the rocker, or
  • in a second configuration or position to define, once the indexing device is integrated into the mechanism 600, a second set of indexed positions of the pull corresponding to a second set of indexed positions of the rod and/or to a second set of indexed positions of the rocker.

Dans ces première et deuxième configurations, le corps d'indexation et l'élément d'indexation sont fixés l'un à l'autre ou en liaison complète l'un avec l'autre. Selon une variante non revendiquée, la liaison peut aussi être une liaison maintenant certains degrés de liberté entre le corps d'indexation et l'élément d'indexation, tant que ce ou ces degrés de liberté ne nuisent pas à la fonction d'indexation. Par exemple, l'élément d'indexation peut s'ébattre perpendiculairement au plan P relativement au corps d'indexation. La liaison mécanique est réalisée lors de l'assemblage du mécanisme ou de la pièce d'horlogerie. Cette liaison n'est de préférence pas démontée pendant les modes d'utilisation normaux ou habituels de la pièce d'horlogerie. Cette liaison n'est de préférence démontée que lors d'une éventuelle opération de service après-vente. Ainsi, l'élément d'indexation est lié cinématiquement au corps d'indexation (notamment l'élément d'indexation et le corps d'indexation sont fixés l'un à l'autre en ce qui concerne les mouvements de rotation autour d'axes perpendiculaires au plan P et de translation selon des axes parallèles au plan P) lors de la manipulation de la première tige, notamment lors du déplacement de la première tige selon la direction D.In these first and second configurations, the indexing body and the indexing element are fixed to each other or in complete connection with each other. According to an unclaimed variant, the connection can also be a connection maintaining certain degrees of freedom between the indexing body and the indexing element, as long as this or these degrees of freedom do not interfere with the indexing function. For example, the indexing element may swing perpendicularly to the plane P relative to the indexing body. The mechanical connection is made during assembly of the mechanism or timepiece. This connection is preferably not dismantled during normal or usual modes of use of the timepiece. This connection is preferably only dismantled during a possible after-sales service operation. Thus, the indexing element is kinematically connected to the indexing body (in particular the indexing element and the indexing body are fixed to each other with regard to the rotational movements about axes perpendicular to the plane P and translational movements along axes parallel to the plane P) during manipulation of the first stem, in particular when moving the first stem in direction D.

Dans le mode de réalisation de mécanisme 600 décrit ci-après, le dispositif de levier-ressort 2 comprend le corps d'indexation 4 et le moyen d'indexation 3. Le corps d'indexation 4 est un corps 4 de levier-ressort. Ce corps est constitué par une première portion 41 rigide dont une première extrémité est articulée selon un axe A41 sur le bâti 99. Le corps de levier-ressort comprend aussi une deuxième portion 42 élastique dont une première extrémité est articulée selon un axe A42 sur le bâti 99. Les première et deuxième portions 41, 42 sont reliées entre elles au niveau de leurs deuxièmes extrémités respectives. Plus particulièrement, la deuxième portion 42 se présente sous la forme d'une lame recourbée formée dans la continuité de la première portion rigide 41. Le corps de levier-ressort présente globalement une forme de boucle ouverte avec les axes A41 et A42 disposés à proximité l'un de l'autre.In the embodiment of mechanism 600 described below, the spring lever device 2 comprises the indexing body 4 and the indexing means 3. The indexing body 4 is a spring lever body 4. This body is constituted by a first rigid portion 41, a first end of which is articulated along an axis A41 on the frame 99. The spring lever body also comprises a second elastic portion 42, a first end of which is articulated along an axis A42 on the frame 99. The first and second portions 41, 42 are connected to each other at their respective second ends. More particularly, the second portion 42 is in the form of a curved blade formed in the continuity of the first rigid portion 41. The spring lever body generally has the shape of an open loop with the axes A41 and A42 arranged close to each other.

La deuxième portion élastique 42 constitue un élément de rappel rappelant l'élément d'indexation et/ou le corps d'indexation dans une configuration de coopération avec la tirette 10.The second elastic portion 42 constitutes a return element recalling the indexing element and/or the indexing body in a configuration of cooperation with the pull tab 10.

L'élément d'indexation 3 se présente ici sous la forme d'une plaque ou d'une came fixée sur le corps 4, en particulier sur la première portion 41 rigide du corps 4 du dispositif de levier-ressort 2, dans une position choisie parmi au moins deux positions possibles.The indexing element 3 is here in the form of a plate or a cam fixed on the body 4, in particular on the first rigid portion 41 of the body 4 of the lever-spring device 2, in a position chosen from at least two possible positions.

Pour ce faire, l'élément d'indexation 3 est de préférence monté déplaçable sur le corps d'indexation 4, notamment monté déplaçable en rotation sur le corps d'indexation autour d'un axe A. Dans ce but, le dispositif d'indexation comprend avantageusement des éléments de positionnement 43, 33a, 33b comme des goupilles coopérant avec des trous, de sorte à positionner, en particulier fixer, l'élément d'indexation 3 dans une position choisie parmi au moins deux positions par rapport au corps d'indexation 4.To do this, the indexing element 3 is preferably mounted so as to be movable on the indexing body 4, in particular mounted so as to be movable in rotation on the indexing body around an axis A. For this purpose, the indexing device advantageously comprises positioning elements 43, 33a, 33b such as pins cooperating with holes, so as to position, in particular fix, the indexing element 3 in a position chosen from at least two positions relative to the indexing body 4.

Pour ce faire, une goupille 43 solidaire de la première portion 41 est prévue pour s'insérer dans une encoche choisie parmi les encoches 33a et 33b de la came 3, de sorte à indexer la came 3 en position en regard du corps 4 de levier-ressort, en particulier de la première portion 41 du corps 4 de levier-ressort. Alternativement, la goupille peut bien sûr être solidaire de la came 3, tandis que les encoches peuvent être formées sur le corps 4 de levier-ressort.To do this, a pin 43 secured to the first portion 41 is provided to be inserted into a notch chosen from the notches 33a and 33b of the cam 3, so as to index the cam 3 in position opposite the spring lever body 4, in particular the first portion 41 of the spring lever body 4. Alternatively, the pin can of course be secured to the cam 3, while the notches can be formed on the spring lever body 4.

Ainsi, le dispositif de levier-ressort 2 se présente sous la forme d'un assemblage comprenant un corps 4 de levier-ressort, ainsi qu'une came 3 indexée et fixée sur ledit corps 4, en particulier sur la première portion rigide 41 dudit corps 4.Thus, the spring lever device 2 is in the form of an assembly comprising a spring lever body 4, as well as a cam 3 indexed and fixed on said body 4, in particular on the first rigid portion 41 of said body 4.

La came 3 comprend une première surface fonctionnelle 31, ainsi qu'une deuxième surface fonctionnelle 32, l'une ou l'autre de ces deux surfaces étant prévue pour coopérer avec un premier doigt 12 de la tirette 10 en fonction de la position de la came 3 sur le corps 4 de levier-ressort.The cam 3 comprises a first functional surface 31, as well as a second functional surface 32, one or the other of these two surfaces being provided to cooperate with a first finger 12 of the pull rod 10 depending on the position of the cam 3 on the spring lever body 4.

La coopération de la première encoche 33a et de la goupille 43 permet de définir une première position de la came 3 sur le corps 4 de levier-ressort. Une fois le dispositif de levier-ressort 2 assemblé, la came 3 est fixée rigidement à la portion 41 du corps 4 de levier-ressort, par exemple par le biais d'une goupille 44. Un tel assemblage du dispositif de levier-ressort 2 peut être réalisé en amont de l'assemblage du mouvement 700, en particulier du mécanisme 600. Alternativement, la came 3 peut être simplement indexée angulairement par la goupille 43 sur le corps 4 du dispositif de levier-ressort 2 et délimitée verticalement par ledit corps 4 et une ébauche 99 du mouvement 700. Ainsi, l'assemblage de la came 3 sur le corps 4 de levier-ressort peut être réalisé lors de l'assemblage du mouvement 700, en particulier du mécanisme 600. L'élément d'indexation peut aussi être chassé sur le corps d'indexation 4.The cooperation of the first notch 33a and the pin 43 makes it possible to define a first position of the cam 3 on the spring lever body 4. Once the spring lever device 2 is assembled, the cam 3 is rigidly fixed to the portion 41 of the spring lever body 4, for example by means of a pin 44. Such an assembly of the spring lever device 2 can be carried out upstream of the assembly of the movement 700, in particular of the mechanism 600. Alternatively, the cam 3 can simply be angularly indexed by the pin 43 on the body 4 of the spring lever device 2 and delimited vertically by said body 4 and a blank 99 of the movement 700. Thus, the assembly of the cam 3 on the spring lever body 4 can be carried out during the assembly of the movement 700, in particular of the mechanism 600. The indexing element can also be driven onto the indexing body 4.

Dans cette première configuration du dispositif de levier-ressort 2, la première surface 31 de la came 3 est susceptible de coopérer avec la tirette, par exemple avec le premier doigt 12 de la tirette 10. Cette surface 31 comprend trois flancs 31a, 31b, 31c qui permettent, en coopération avec le doigt 12 de définir trois positions, notamment trois positions angulaires, stables ou indexées de la tirette. Ces positions stables ou indexées de la tirette permettent de définir :

  • trois positions axiales distinctes de la première tige 5, en l'occurrence les positions P1, P2 et P3 de la première tige 5, qui sont des positions stables ou indexées, et/ou
  • trois positions angulaires distinctes de la bascule 6, qui sont des positions stables ou indexées.
In this first configuration of the spring lever device 2, the first surface 31 of the cam 3 is capable of cooperating with the pull tab, for example with the first finger 12 of the pull tab 10. This surface 31 comprises three flanks 31a, 31b, 31c which make it possible, in cooperation with the finger 12, to define three positions, in particular three angular, stable or indexed positions of the pull tab. These stable or indexed positions of the pull tab make it possible to define:
  • three distinct axial positions of the first rod 5, in this case positions P1, P2 and P3 of the first rod 5, which are stable or indexed positions, and/or
  • three distinct angular positions of the rocker 6, which are stable or indexed positions.

Dans une première position P1, le premier flanc 31a de la came 3 est en appui à l'encontre du premier doigt 12 de la tirette 10 sous l'effet de la deuxième portion 42 élastique du corps 4 de levier-ressort, ce qui provoque l'appui de la tirette 10 à l'encontre d'une surface 99a de butée d'une ébauche 99 du mécanisme 600, comme représenté sur la figure 5. Dans cette première position P1, les dentures 72, 73 du pignon coulant 7 sont hors de portée des roues prenant part aux différentes chaînes de réglage du mécanisme, et ce grâce au positionnement de la bascule 6 dont une extrémité 61 est en appui à l'encontre d'une surface de butée 13 de la tirette sous l'effet du ressort 98. Par ailleurs, dans cette première position P1, la chaîne 500 de remontage est embrayée.In a first position P1, the first flank 31a of the cam 3 bears against the first finger 12 of the pull tab 10 under the effect of the second elastic portion 42 of the spring lever body 4, which causes the pull tab 10 to press against a stop surface 99a of a blank 99 of the mechanism 600, as shown in the figure 5 . In this first position P1, the teeth 72, 73 of the sliding pinion 7 are out of reach of the wheels taking part in the various adjustment chains of the mechanism, thanks to the positioning of the lever 6, one end 61 of which bears against a stop surface 13 of the pull rod under the effect of the spring 98. Furthermore, in this first position P1, the winding chain 500 is engaged.

Une traction de la première tige 5 vers l'extérieur du mouvement 700 depuis la position P1, selon la direction D, induit une rotation de la tirette 10 en sens antihoraire. Le premier doigt 12 agit alors à l'encontre de la première surface 31 de la came 3, et donc à l'encontre du corps 4 de levier-ressort, et ce jusqu'à ce que celui-ci se positionne dans un creux formé par le deuxième flanc 31b, comme représenté sur la figure 6. Dans cette deuxième position P2, la bascule 6 a pivoté vers l'extérieur du mouvement 700 (dans le sens horaire) sous l'effet du ressort 98, de sorte que la denture de chant 72 du pignon coulant 7 puisse engrener avec une denture d'une roue 20 d'une première chaîne 200 de réglage d'une indication horaire ou dérivée de l'heure, en particulier une indication calendaire telle qu'une indication des quantièmes. Dans cette deuxième position P2, l'extrémité 61 de la bascule a perdu le contact avec la tirette 10. Par ailleurs, la chaîne 500 de remontage est débrayée.A pull of the first rod 5 towards the outside of the movement 700 from the position P1, in the direction D, induces a rotation of the pull rod 10 in a counterclockwise direction. The first finger 12 then acts against the first surface 31 of the cam 3, and therefore against the body 4 of the spring lever, and this until the latter is positioned in a hollow formed by the second flank 31b, as shown in the figure 6 . In this second position P2, the lever 6 has pivoted towards the outside of the movement 700 (clockwise) under the effect of the spring 98, so that the edge teeth 72 of the sliding pinion 7 can mesh with a toothing of a wheel 20 of a first chain 200 for adjusting a time indication or a time-derived indication, in particular a calendar indication such as a date indication. In this second position P2, the end 61 of the lever has lost contact with the pull-out 10. Furthermore, the winding chain 500 is disengaged.

Une autre traction de la première tige 5 vers l'extérieur du mouvement 700 depuis la position P2, selon la direction D, induit une nouvelle fois une rotation de la tirette 10 en sens antihoraire. Le premier doigt 12 agit alors à l'encontre de la première surface 31 de la came 3, et donc à l'encontre du corps 4 de levier-ressort, et ce jusqu'à ce que celui-ci se positionne à l'encontre du troisième flanc 31c, comme représenté sur la figure 7. Dans sa rotation, la tirette agit sur l'extrémité 61 de la bascule 6 par le biais d'un deuxième doigt 14 afin d'entraîner celle-ci vers l'intérieur du mouvement 700 (dans le sens anti-horaire), à l'encontre du ressort 98, de sorte que la denture frontale 73 du pignon coulant 7 engrène avec un pignon 30 d'une deuxième chaîne 300 de réglage d'une indication horaire ou dérivée de l'heure, en particulier de mise à l'heure du mouvement 700.Another pull of the first rod 5 towards the outside of the movement 700 from the position P2, in the direction D, once again induces a rotation of the pull rod 10 in a counterclockwise direction. The first finger 12 then acts against the first surface 31 of the cam 3, and therefore against the body 4 of the spring lever, until the latter is positioned against the third flank 31c, as shown in the figure 7 . In its rotation, the pull rod acts on the end 61 of the rocker 6 by means of a second finger 14 in order to drive the latter towards the inside of the movement 700 (in the anti-clockwise direction), against the spring 98, so that the front teeth 73 of the sliding pinion 7 mesh with a pinion 30 of a second chain 300 for adjusting a time indication or a time-derived indication, in particular for setting the time of the movement 700.

La coopération de la deuxième encoche 33b et de la goupille 43 permet de définir une deuxième position de la came 3 sur le corps 4 du dispositif de levier-ressort 2.The cooperation of the second notch 33b and the pin 43 makes it possible to define a second position of the cam 3 on the body 4 of the spring lever device 2.

Dans cette deuxième configuration du dispositif de levier-ressort 2, la deuxième surface 32 de la came 3 est susceptible de coopérer avec la tirette 10, notamment avec le premier doigt 12 de la tirette 10. Cette surface 32 comprend deux flancs 32a, 32b qui permettent de définir deux positions axiales distinctes de la première tige 5, en l'occurrence les positions P1 et P3 de la première tige 5. Ces positions P1 et P3 de la première tige 5 sont par exemple identiques à celles évoquées précédemment.In this second configuration of the spring lever device 2, the second surface 32 of the cam 3 is capable of cooperating with the pull rod 10, in particular with the first finger 12 of the pull rod 10. This surface 32 comprises two flanks 32a, 32b which make it possible to define two distinct axial positions of the first rod 5, in this case the positions P1 and P3 of the first rod 5. These positions P1 and P3 of the first rod 5 are for example identical to those mentioned previously.

Dans la première position P1, le premier flanc 32a de la came 3 est en appui à l'encontre du premier doigt 12 de la tirette 10 sous l'effet de la deuxième portion 42 élastique du corps 4 de levier-ressort, ce qui provoque l'appui de la tirette 10 à l'encontre d'une surface 99a de butée d'une ébauche 99 du mécanisme 600, comme représenté sur la figure 8. Dans cette première position P1, les dentures 72, 73 du pignon coulant 7 sont hors de portée des roues prenant part aux différentes chaînes de réglage du mécanisme, et ce grâce au positionnement de la bascule 6 dont l'extrémité 61 est en appui à l'encontre d'une surface de butée 13 de la tirette sous l'effet du ressort 98. Par ailleurs, dans cette première position P1, la chaîne 500 de remontage est embrayée.In the first position P1, the first flank 32a of the cam 3 bears against the first finger 12 of the pull tab 10 under the effect of the second elastic portion 42 of the spring lever body 4, which causes the pull tab 10 to bear against a stop surface 99a of a blank 99 of the mechanism 600, as shown in FIG. figure 8 . In this first position P1, the teeth 72, 73 of the sliding pinion 7 are out of reach of the wheels taking part in the various adjustment chains of the mechanism, thanks to the positioning of the lever 6, the end 61 of which bears against a stop surface 13 of the pull rod under the effect of the spring 98. Furthermore, in this first position P1, the winding chain 500 is engaged.

Une traction de la première tige 5 vers l'extérieur du mouvement 700 depuis la position P1, selon la direction D, induit une rotation de la tirette 10 en sens antihoraire. Le premier doigt 12 agit alors à l'encontre de la deuxième surface 32 de la came 3, et donc à l'encontre du corps 4 de levier-ressort, et ce jusqu'à ce que celui-ci se positionne à l'encontre du deuxième flanc 32b, comme représenté sur la figure 9.A pull of the first rod 5 towards the outside of the movement 700 from the position P1, in the direction D, induces a rotation of the pull rod 10 in a counterclockwise direction. The first finger 12 then acts against the second surface 32 of the cam 3, and therefore against the body 4 of the spring lever, and this until the latter is positioned against the second flank 32b, as shown in the figure 9 .

Dans sa rotation, la tirette agit sur l'extrémité 61 de la bascule 6 par le biais du deuxième doigt 14 afin d'entraîner celle-ci vers l'intérieur du mouvement 700, à l'encontre du ressort 98, de sorte que la denture frontale 73 du pignon coulant 7 engrène avec un pignon 30 d'une deuxième chaîne 300 de réglage d'une indication horaire ou dérivée de l'heure, en particulier de mise à l'heure du mouvement 700.In its rotation, the pull-out acts on the end 61 of the lever 6 by means of the second finger 14 in order to drive the latter towards the inside of the movement 700, against the spring 98, so that the front teeth 73 of the sliding pinion 7 mesh with a pinion 30 of a second chain 300 for adjusting a time indication or a time-derived indication, in particular for setting the time of the movement 700.

L'amplitude angulaire parcourue par la tirette 10 entre les positions P1 et P3 de la tige, lorsque le dispositif de levier-ressort 2 se trouve dans cette deuxième configuration, correspond ici à la somme des amplitudes angulaires parcourues par la tirette entre les positions P1 et P2, et P2 et P3, lorsque le dispositif de levier-ressort 2 se trouve dans la première configuration. De manière analogue, l'amplitude du déplacement parcouru par la première tige 5 entre les positions P1 et P3, lorsque le dispositif de levier-ressort 2 se trouve dans cette deuxième configuration, correspond ici à la somme des amplitudes des déplacements parcourus par la première tige 5 entre les positions P1 et P2, et P2 et P3, lorsque le dispositif de levier-ressort 2 se trouve dans la première configuration.The angular amplitude traveled by the pull rod 10 between the positions P1 and P3 of the rod, when the spring lever device 2 is in this second configuration, corresponds here to the sum of the angular amplitudes traveled by the pull rod between the positions P1 and P2, and P2 and P3, when the spring lever device 2 is in the first configuration. Similarly, the amplitude of the displacement traveled by the first rod 5 between the positions P1 and P3, when the spring lever device 2 is in this second configuration, corresponds here to the sum of the amplitudes of the displacements traveled by the first rod 5 between the positions P1 and P2, and P2 and P3, when the spring lever device 2 is in the first configuration.

Comme vu précédemment, une première configuration ou position de l'élément d'indexation sur le corps d'indexation permet de définir trois positions de tirette relativement à un bâti 99 et une deuxième configuration ou position de l'élément d'indexation sur le corps d'indexation permet de définir deux positions de tirette relativement au bâti 99.As seen previously, a first configuration or position of the indexing element on the indexing body makes it possible to define three pull positions relative to a frame 99 and a second configuration or position of the indexing element on the indexing body makes it possible to define two pull positions relative to the frame 99.

Dans une variante non représentée de ce premier mode de réalisation, le dispositif de levier-ressort peut être remplacé par un ensemble dispositif de levier et élément de rappel, le dispositif de levier et l'élément de rappel étant réalisés en deux pièces distinctes et l'élément de rappel rappelant le dispositif de levier contre la tirette. Dans ce cas, le dispositif de levier comprend :

  • un corps d'indexation formé par un levier proprement dit, et
  • un élément d'indexation comprenant au moins deux jeux de flancs de définition de positions d'indexation de tirette et monté sur le corps d'indexation.
In a variant not shown of this first embodiment, the lever-spring device can be replaced by a lever device and return element assembly, the lever device and the return element being made in two separate parts and the return element recalling the lever device against the pull tab. In this case, the lever device comprises:
  • an indexing body formed by a lever itself, and
  • an indexing element comprising at least two sets of indexing position defining flanks of the pull tab and mounted on the indexing body.

Un deuxième mode de réalisation d'une pièce d'horlogerie 1000 est décrit ci-après en référence aux figures 10 à 17.A second embodiment of a timepiece 1000 is described below with reference to Figures 10 to 17 .

La pièce d'horlogerie 1000 est par exemple une montre, en particulier une montre bracelet.The timepiece 1000 is for example a watch, in particular a wristwatch.

La pièce d'horlogerie 1000 comprend un mouvement horloger 700 destiné à être monté dans une boîte de pièce d'horlogerie afin de le protéger de l'environnement extérieur.The 1000 timepiece includes a 700 watch movement intended to be mounted in a timepiece case in order to protect it from the external environment.

Le mouvement horloger 700 peut être un mouvement électronique ou un mouvement mécanique, notamment un mouvement automatique.The 700 watch movement can be an electronic movement or a mechanical movement, especially an automatic movement.

Le mouvement horloger 700 comprend un mécanisme horloger 600. Notamment, le mécanisme horloger peut être un mécanisme mettant en oeuvre un dispositif de tirette. Le mécanisme horloger comprend un dispositif d'indexation 100' de tirette et un bâti 99. Par « indexation d'un dispositif de tirette », on entend la définition de différentes positions stables du dispositif de tirette. Ces positions stables sont séparées par un continuum de positions intermédiaires instables. L'utilisateur fait passer, par une action mécanique, notamment une action mécanique sur une tige, le dispositif de tirette d'une position stable à une autre, via un continuum de positions intermédiaires instables. Entre deux positions stables ou deux positions indexées ou deux positions d'indexations, le dispositif de tirette passe transitoirement par un continuum de positions intermédiaires instables.The watch movement 700 comprises a watch mechanism 600. In particular, the watch mechanism may be a mechanism implementing a pull device. The watch mechanism comprises a pull indexing device 100' and a frame 99. By "indexing a pull device", we mean the definition of different stable positions of the pull device. These stable positions are separated by a continuum of unstable intermediate positions. The user moves, by a mechanical action, in particular a mechanical action on a rod, the pull device from one stable position to another, via a continuum of unstable intermediate positions. Between two stable positions or two indexed positions or two indexing positions, the pull device transitorily passes through a continuum of unstable intermediate positions.

Dans le deuxième mode de réalisation, le dispositif d'indexation 100' comprend un dispositif de tirette 10'. Le dispositif d'indexation de tirette comprend de préférence aussi un levier et un élément de rappel, comme un ressort. L'élément de rappel et le levier peuvent être constitués par un levier-ressort 2' comprenant un élément de rappel 42', comme représenté sur les figures 10 et 13 à 17.In the second embodiment, the indexing device 100' comprises a pull device 10'. The pull indexing device preferably also comprises a lever and a return element, such as a spring. The return element and the lever may be constituted by a spring lever 2' comprising a return element 42', as shown in the Figures 10 And 13 to 17 .

Le dispositif d'indexation, en particulier le dispositif de tirette, comprend :

  • un corps d'indexation 1', et
  • un élément d'indexation 3' comprenant au moins deux jeux de flancs 31 a', 31b', 31c' ; 32a', 32b' de définition de positions d'indexation de tirette et monté sur le corps d'indexation 1'.
The indexing device, in particular the pull device, comprises:
  • an indexing body 1', and
  • an indexing element 3' comprising at least two sets of flanks 31a', 31b', 31c';32a',32b' for defining pull tab indexing positions and mounted on the indexing body 1'.

De préférence, le deuxième mode de réalisation de la pièce d'horlogerie ne diffère du premier mode de réalisation de la pièce d'horlogerie que par la localisation de l'élément d'indexation et du corps d'indexation. Dans le premier mode de réalisation, l'élément d'indexation est monté sur un levier ou sur un levier-ressort qui constitue le corps d'indexation et l'élément d'indexation coopère avec un doigt prévu sur la tirette. Dans le deuxième mode de réalisation de la pièce d'horlogerie, la situation est inversée, c'est-à-dire que

  • l'élément d'indexation est monté sur le corps 1' d'un dispositif de tirette 10', le corps 1' constituant le corps d'indexation, et
  • l'élément d'indexation coopère avec un doigt prévu sur le levier ou sur le levier-ressort.
Preferably, the second embodiment of the timepiece differs from the first embodiment of the timepiece only in the location of the indexing element and the indexing body. In the first embodiment, the indexing element is mounted on a lever or on a spring lever which constitutes the indexing body and the indexing element cooperates with a finger provided on the pull. In the second embodiment of the timepiece, the situation is reversed, that is to say that
  • the indexing element is mounted on the body 1' of a pull device 10', the body 1' constituting the indexing body, and
  • the indexing element cooperates with a finger provided on the lever or on the spring lever.

Le corps d'indexation 1' de tirette 10' et l'élément d'indexation 3' sont agencés ou configurés de sorte à définir au moins deux positions de fixation, de l'élément d'indexation 3' sur le corps d'indexation 1'. En effet, l'élément d'indexation peut être monté sur le corps d'indexation :

  • dans une première configuration ou position, pour définir, une fois que le dispositif d'indexation est intégré au mécanisme 600, un premier ensemble de positions indexées du dispositif de tirette correspondant à un premier ensemble de positions indexées de la tige et/ou à un premier ensemble de positions indexées de la bascule, ou
  • dans une deuxième configuration ou position, pour définir, une fois que le dispositif d'indexation est intégré au mécanisme 600, un deuxième ensemble de positions indexées du dispositif de tirette correspondant à un deuxième ensemble de positions indexées de la tige et/ou à un deuxième ensemble de positions indexées de la bascule.
The indexing body 1' of the pull tab 10' and the indexing element 3' are arranged or configured so as to define at least two fixing positions of the indexing element 3' on the indexing body 1'. Indeed, the indexing element can be mounted on the indexing body:
  • in a first configuration or position, to define, once the indexing device is integrated into the mechanism 600, a first set of indexed positions of the pull device corresponding to a first set of indexed positions of the rod and/or to a first set of indexed positions of the rocker, or
  • in a second configuration or position, to define, once the indexing device is integrated into the mechanism 600, a second set of indexed positions of the pull device corresponding to a second set of indexed positions of the rod and/or to a second set of indexed positions of the rocker.

Dans ces premières et deuxièmes configurations, le corps d'indexation et l'élément d'indexation sont fixés l'un à l'autre ou en liaison complète l'un avec l'autre. Selon une variante non revendiquée, la liaison peut aussi être une liaison maintenant certains degrés de liberté entre le corps d'indexation et l'élément d'indexation, tant que ce ou ces degrés de liberté ne nuisent pas à la fonction d'indexation. Par exemple, l'élément d'indexation peut s'ébattre perpendiculairement au plan P relativement au corps d'indexation. La liaison mécanique est réalisée lors de l'assemblage du mécanisme ou de la pièce d'horlogerie. Cette liaison n'est de préférence pas démontée pendant les modes d'utilisation normaux ou habituels de la pièce d'horlogerie. Cette liaison n'est de préférence démontée que lors d'une éventuelle opération de service après-vente, si nécessaire. Ainsi, l'élément d'indexation est lié cinématiquement au corps d'indexation ou corps de tirette (notamment l'élément d'indexation et le corps d'indexation sont fixés l'un à l'autre en ce qui concerne les mouvements de rotation autour d'axes perpendiculaires au plan P et de translation selon des axes parallèles au plan P) lors de la manipulation de la première tige, notamment lors du déplacement de la première tige selon la direction D.In these first and second configurations, the indexing body and the indexing element are fixed to each other or in complete connection with each other. According to an unclaimed variant, the connection may also be a connection maintaining certain degrees of freedom between the indexing body and the indexing element, as long as this or these degrees of freedom do not harm the indexing function. For example, the indexing element may swing perpendicular to the plane P relative to the indexing body. The mechanical connection is made during the assembly of the mechanism or the timepiece. This connection is preferably not dismantled during normal or usual modes of use of the timepiece. This connection is preferably dismantled only during a possible after-sales service operation, if necessary. Thus, the indexing element is kinematically linked to the indexing body or pull body (in particular the indexing element and the indexing body are fixed to each other with regard to the rotational movements about axes perpendicular to the plane P and translational movements along axes parallel to the plane P) during the manipulation of the first rod, in particular during the movement of the first rod in the direction D.

Dans le mode de réalisation de mécanisme 600 décrit ci-après, le dispositif de tirette 10' faisant office de tirette comprend le corps d'indexation 1' et le moyen d'indexation 3'. Le corps d'indexation 1' est un corps 1 ' du dispositif de tirette. Ce corps 1' du dispositif de tirette 10' (ou corps 1' de tirette) est articulé selon un axe A1 sur le bâti 99In the embodiment of mechanism 600 described below, the pull device 10' acting as a pull comprises the indexing body 1' and the indexing means 3'. The indexing body 1' is a body 1' of the pull device. This body 1' of the pull device 10' (or body 1' of the pull) is articulated along an axis A1 on the frame 99

L'élément d'indexation 3' se présente ici sous la forme d'une plaque ou d'une came fixée sur le corps 1' dans une position choisie parmi au moins deux positions possibles.The indexing element 3' is here in the form of a plate or a cam fixed on the body 1' in a position chosen from at least two possible positions.

Pour ce faire, l'élément d'indexation 3' est de préférence monté déplaçable sur le corps d'indexation 1', notamment monté déplaçable en rotation sur le corps d'indexation autour d'un axe A'. Dans ce but, le dispositif d'indexation comprend avantageusement des éléments de positionnement 13', 33a', 33b' comme des goupilles coopérant avec des trous, de sorte à positionner, en particulier fixer, l'élément d'indexation 3' dans une position choisie parmi au moins deux positions par rapport au corps d'indexation 1'.To do this, the indexing element 3' is preferably mounted so as to be movable on the indexing body 1', in particular mounted so as to be movable in rotation on the indexing body about an axis A'. For this purpose, the indexing device advantageously comprises positioning elements 13', 33a', 33b' such as pins cooperating with holes, so as to position, in particular fix, the indexing element 3' in a position chosen from at least two positions relative to the indexing body 1'.

Par exemple, une goupille 13' solidaire du corps 1' est prévue pour s'insérer dans une encoche choisie parmi les encoches 33a' et 33b' de la came 3', de sorte à indexer la came 3' en position en regard du corps 1'.For example, a pin 13' secured to the body 1' is designed to be inserted into a notch chosen from among the notches 33a' and 33b' of the cam 3', so as to index the cam 3' in position opposite the body 1'.

Alternativement, la goupille peut bien sûr être solidaire de la came 3', tandis que les encoches peuvent être formées sur le corps 1'.Alternatively, the pin can of course be integral with the cam 3', while the notches can be formed on the body 1'.

Ainsi, le dispositif de tirette 10' se présente sous la forme d'un assemblage comprenant un corps 1' de tirette, ainsi qu'une came 3' indexée et fixée sur le corps 1' de tirette.Thus, the pull device 10' is in the form of an assembly comprising a pull body 1', as well as a cam 3' indexed and fixed on the pull body 1'.

La came 3' comprend une première surface fonctionnelle 31', ainsi qu'une deuxième surface fonctionnelle 32', l'une ou l'autre de ces deux surfaces étant prévue pour coopérer avec un premier doigt 12' du levier ou du levier-ressort 2' en fonction de la position de la came 3' sur le corps 1' de tirette.The cam 3' comprises a first functional surface 31', as well as a second functional surface 32', one or the other of these two surfaces being provided to cooperate with a first finger 12' of the lever or of the spring lever 2' depending on the position of the cam 3' on the body 1' of the pull tab.

La coopération de la première encoche 33a' et de la goupille 13' permet de définir une première position de la came 3' sur le corps 1 ' de tirette. Une fois le dispositif de tirette 10' assemblé, la came 3' est fixée rigidement au corps 1', par exemple par le biais d'une goupille 14'. Un tel assemblage du dispositif de tirette peut être réalisé en amont de l'assemblage du mouvement 700, en particulier du mécanisme 600. Alternativement, la came 3' peut être simplement indexée angulairement par la goupille 13' sur le corps 1' et délimitée verticalement par le corps 1 ' et une ébauche 99 du mouvement 700. Ainsi, l'assemblage de la came 3' sur le corps 1' peut être réalisé lors de l'assemblage du mouvement 700, en particulier du mécanisme 600. L'élément d'indexation 3' peut aussi être chassé sur le corps 1' de tirette.The cooperation of the first notch 33a' and the pin 13' makes it possible to define a first position of the cam 3' on the pull body 1'. Once the pull device 10' is assembled, the cam 3' is rigidly fixed to the body 1', for example by means of a pin 14'. Such an assembly of the pull device can be carried out upstream of the assembly of the movement 700, in particular of the mechanism 600. Alternatively, the cam 3' can be simply angularly indexed by the pin 13' on the body 1' and delimited vertically by the body 1' and a blank 99 of the movement 700. Thus, the assembly of the cam 3' on the body 1' can be carried out during the assembly of the movement 700, in particular of the mechanism 600. The indexing element 3' can also be driven onto the pull body 1'.

Dans une première configuration du dispositif de tirette 10', la première surface 31' de la came 3' est susceptible de coopérer avec le levier 2', par exemple avec le doigt 12' du levier. Cette surface 31' comprend trois flancs 31a', 31b', 31c' qui permettent, en coopération avec le doigt 12' de définir trois positions angulaires stables ou indexées du dispositif de tirette 10'. Ces positions angulaires stables ou indexées du dispositif de tirette 10' permettent de définir :

  • trois positions axiales distinctes de la première tige 5, en l'occurrence les positions P1, P2 et P3 de la première tige 5, qui sont des positions stables ou indexées, et/ou
  • trois positions angulaires distinctes de la bascule 6, qui sont des positions stables ou indexées.
In a first configuration of the pull device 10', the first surface 31' of the cam 3' is capable of cooperating with the lever 2', for example with the finger 12' of the lever. This surface 31' comprises three flanks 31a', 31b', 31c' which make it possible, in cooperation with the finger 12', to define three stable or indexed angular positions of the pull device 10'. These stable or indexed angular positions of the pull device 10' allow to define:
  • three distinct axial positions of the first rod 5, in this case positions P1, P2 and P3 of the first rod 5, which are stable or indexed positions, and/or
  • three distinct angular positions of the rocker 6, which are stable or indexed positions.

La coopération de la deuxième encoche 33b' et de la goupille 13' permet de définir une deuxième position de la came 3' sur le corps 1' de tirette.The cooperation of the second notch 33b' and the pin 13' makes it possible to define a second position of the cam 3' on the body 1' of the pull tab.

Dans cette deuxième configuration du dispositif de tirette 10', la deuxième surface 32' de la came 3' est susceptible de coopérer avec le levier 2', notamment avec le premier doigt 12' du levier 2'. Cette surface 32' comprend deux flancs 32a', 32b' qui permettent de définir deux positions axiales distinctes de la première tige 5, en l'occurrence les positions P1 et P3 de la première tige 5. Ces positions P1 et P3 de la première tige 5 sont par exemple identiques à celles évoquées précédemment.In this second configuration of the pull rod device 10', the second surface 32' of the cam 3' is capable of cooperating with the lever 2', in particular with the first finger 12' of the lever 2'. This surface 32' comprises two flanks 32a', 32b' which make it possible to define two distinct axial positions of the first rod 5, in this case the positions P1 and P3 of the first rod 5. These positions P1 and P3 of the first rod 5 are for example identical to those mentioned previously.

Comme vu précédemment, une première configuration ou position de l'élément d'indexation sur le corps d'indexation permet de définir trois positions de tirette relativement à un bâti 99 et une deuxième configuration ou position de l'élément d'indexation sur le corps d'indexation permet de définir deux positions de tirette relativement au bâti 99.As seen previously, a first configuration or position of the indexing element on the indexing body makes it possible to define three pull positions relative to a frame 99 and a second configuration or position of the indexing element on the indexing body makes it possible to define two pull positions relative to the frame 99.

Dans ce deuxième mode de réalisation, le dispositif d'indexation comprend un élément de rappel constitué par exemple par un ressort ou par une partie ressort 42' du levier-ressort 2', l'élément de rappel rappelant l'élément d'indexation 3' dans une configuration de coopération avec le levier-ressort 2'.In this second embodiment, the indexing device comprises a return element constituted for example by a spring or by a spring part 42' of the spring lever 2', the return element recalling the indexing element 3' in a configuration of cooperation with the spring lever 2'.

Dans les modes de réalisation décrits, l'élément d'indexation est fixé ou rapporté sur le corps d'une tirette ou sur le corps d'un levier ou sur le corps d'un levier-ressort. Dans un mode de réalisation alternatif de dispositif d'indexation de tirette, l'élément d'indexation peut être indexé ou fixé ou rapporté sur un élément intermédiaire disposé à l'interface d'un levier ou levier-ressort et d'une tirette.In the described embodiments, the indexing element is fixed or attached to the body of a pull tab or to the body of a lever or to the body of a spring lever. In an alternative embodiment of a pull tab indexing device, the indexing element may be indexed or fixed or attached to an intermediate element disposed at the interface of a lever or spring lever and a pull tab.

Bien entendu, selon le mode de réalisation de dispositif de tirette, le levier-ressort peut se présenter plus simplement sous la forme d'un ressort. Les doigts de tirette peuvent aussi, au besoin, être remplacés par des goupilles.Of course, depending on the embodiment of the pull device, the spring lever can be more simply in the form of a spring. The pull fingers can also, if necessary, be replaced by pins.

Dans les modes de réalisation et variantes décrits plus haut, les positions P1 correspondent à une position de remontage du mouvement 700. En alternative, quels que soient les modes de réalisation et variantes, les différentes positions P1 pourraient correspondre à des fonctions horlogères différentes.In the embodiments and variants described above, the positions P1 correspond to a winding position of the movement 700. Alternatively, whatever the embodiments and variants, the different positions P1 could correspond to different watch functions.

Dans les modes de réalisation et variantes décrits, le dispositif d'indexation permet de réaliser, selon la configuration de l'élément d'indexation, deux ou trois positions d'indexation de tirette. Bien entendu, un tel dispositif d'indexation peut être modifié pour permettre plus de deux configurations de l'élément d'indexation sur le corps d'indexation. Par exemple, l'élément d'indexation peut présenter trois surfaces ou plus, permettant de définir autant de jeux de positions d'indexation de tirette. De même, chaque surface peut définir une ou deux ou trois ou quatre positions d'indexation (ou plus encore). En outre, une première surface peut définir n premières positions d'indexation et une deuxième surface peut définir n deuxièmes positions d'indexation, les premières et deuxièmes positions d'indexations étant différentes les unes des autres ou l'une des premières positions étant différente de n'importe laquelle des deuxièmes positions, avec n un nombre entier naturel. Enfin, une première surface peut définir n premières positions d'indexation et une deuxième surface peut définir m deuxièmes positions d'indexation, avec n et m des nombres entiers naturels et n différent de m.In the embodiments and variants described, the indexing device allows, depending on the configuration of the indexing element, two or three pull tab indexing positions. Of course, such an indexing device can be modified to allow more than two configurations of the indexing element on the indexing body. For example, the indexing element can have three or more surfaces, allowing to define as many sets of pull tab indexing positions. Similarly, each surface can define one or two or three or four indexing positions (or more). Furthermore, a first surface can define n first indexing positions and a second surface can define n second indexing positions, the first and second indexing positions being different from each other or one of the first positions being different from any of the second positions, with n a natural integer. Finally, a first surface can define n first indexing positions and a second surface can define m second indexing positions, with n and m natural integers and n different from m.

Quel que soit le mode de réalisation ou la variante, l'élément d'indexation 3 ; 3' peut être délimité par le corps d'indexation 4 ; 1', d'une part, et par le bâti 99, d'autre part. En alternative, quel que soit le mode de réalisation ou la variante, l'élément d'indexation 3' peut être monté en liaison complète sur le corps d'indexation 4 ; 1'. Par exemple, l'élément d'indexation peut être chassé sur le corps d'indexation.Regardless of the embodiment or variant, the indexing element 3; 3' may be delimited by the indexing body 4; 1', on the one hand, and by the frame 99, on the other hand. Alternatively, regardless of the embodiment or variant, the indexing element 3' may be mounted in complete connection on the indexing body 4; 1'. For example, the indexing element may be driven onto the indexing body.

De préférence, quel que soit le mode de réalisation ou la variante :

  • une première position indexée de tirette permet le remontage du mouvement d'horlogerie, c'est-à-dire que la première position indexée de tirette définit des configurations et agencements de composants du mouvement liant la première tige à une chaîne de remontage du mouvement,
  • une deuxième position indexée de tirette permet une correction, notamment une correction rapide, d'une fonction dérivée de l'heure du mouvement d'horlogerie, c'est-à-dire que la deuxième position indexée de tirette définit des configurations et agencements de composants du mouvement liant la première tige à une chaîne de correction d'une fonction dérivée de l'heure du mouvement d'horlogerie, et
  • une troisième position indexée de tirette permet une mise à l'heure du mouvement d'horlogerie, c'est-à-dire que la troisième position indexée de tirette définit des configurations et agencements de composants du mouvement liant la première tige à une chaîne de mise à l'heure du mouvement d'horlogerie.
Preferably, regardless of the embodiment or variant:
  • a first indexed pull position allows the winding of the watch movement, that is to say that the first indexed pull position defines configurations and arrangements of components of the movement linking the first stem to a winding chain of the movement,
  • a second indexed pull position allows a correction, in particular a rapid correction, of a function derived from the time of the clockwork movement, that is to say that the second indexed pull position defines configurations and arrangements of components of the movement linking the first stem to a correction chain of a function derived from the time of the clockwork movement, and
  • a third indexed pull position allows the time to be set on the clockwork movement, i.e. the third indexed pull position defines configurations and arrangements of components of the movement linking the first stem to a time-setting chain of the clockwork movement.

De préférence, la première position de tirette correspond à une position de la première tige dans laquelle la tige est la plus enfoncée dans le mouvement. La deuxième position de tirette correspond à la première position indexée et stable de la première tige que l'on rencontre quand on exerce une action de traction sur la première tige alors qu'elle se trouve en première position. La troisième position de tirette correspond à la première position indexée et stable de la première tige que l'on rencontre quand on exerce une action de traction sur la première tige alors qu'elle se trouve en deuxième position.Preferably, the first pull position corresponds to a position of the first rod in which the rod is most deeply engaged in the movement. The second pull position corresponds to the first indexed and stable position of the first rod encountered when a pulling action is exerted on the first rod while it is in the first position. The third pull position corresponds to the first indexed and stable position of the first rod encountered when a pulling action is exerted on the first rod while it is in the second position.

L'invention porte encore sur un procédé de montage d'un dispositif d'indexation 100, 100' de tirette tel que décrit précédemment ou sur un procédé de montage d'un mécanisme 600 tel que décrit précédemment ou sur un procédé de montage d'un mouvement 700 tel que décrit précédemment ou sur un procédé de montage d'une pièce d'horlogerie telle que décrite précédemment.The invention also relates to a method of mounting an indexing device 100, 100' of a pull tab as described above or to a method of mounting a mechanism 600 as described above or to a method of mounting a movement 700 as described above or to a method of mounting a timepiece as described above.

Le procédé comprend les étapes suivantes :

  • une étape de fourniture du corps d'indexation 4 ; 1' ,
  • une étape de fourniture de l'élément d'indexation 3 ; 3',
  • une étape de montage de l'élément d'indexation 3 ; 3' sur le corps d'indexation 4 ; 1' :
    • dans une première position, ou
    • dans une deuxième position.
The process includes the following steps:
  • a step of providing the indexing body 4; 1',
  • a step of providing the indexing element 3; 3',
  • a step of mounting the indexing element 3; 3' on the indexing body 4; 1':
    • in a first position, or
    • in a second position.

Bien entendu, si l'élément d'indexation présente plus de deux surfaces, l'élément d'indexation peut alternativement être monté sur le corps d'indexation dans une troisième position.Of course, if the indexing element has more than two surfaces, the indexing element can alternatively be mounted on the indexing body in a third position.

Grâce aux solutions décrites précédemment, un élément d'indexation de tirette peut être choisi et configuré en amont de l'assemblage du mouvement de pièce d'horlogerie, de sorte que le dispositif de tirette puisse positionner la tige du mécanisme auquel il prend part selon notamment deux ou trois positions. Grâce à ces solutions, dans lesquelles un élément d'indexation de tirette peut être choisi et configuré en amont de l'assemblage du mouvement de pièce d'horlogerie, le risque qu'un horloger puisse faire une erreur d'assemblage lors de l'assemblage du mouvement auquel le mécanisme prend part, ou lors d'une opération de rhabillage, est annulé.Using the solutions described above, a pull tab indexing element can be selected and configured upstream of the assembly of the timepiece movement, such that the pull device can position the stem of the mechanism in which it takes part in particular according to two or three positions. Thanks to these solutions, in which a pull indexing element can be chosen and configured upstream of the assembly of the timepiece movement, the risk that a watchmaker could make an assembly error when assembling the movement in which the mechanism takes part, or during a re-dressing operation, is eliminated.

Les solutions décrites précédemment seront avantageusement mises en oeuvre, quand il s'agira, dans la construction de mouvements de pièce d'horlogerie, de constituer des familles de calibres, afin d'utiliser autant que possible les mêmes composants ou assemblages pour des mouvements dont la présentation finale est modulée par adjonction d'éléments propres à la complication désirée. Ainsi, à titre d'exemple, un mouvement à calendrier et un mouvement à fuseaux horaires d'une même famille pourront se partager un même mouvement de base et un dispositif d'indexation de tirette présentant les mêmes composants, ces composants, en particulier l'élément d'indexation, étant simplement configurés différemment pour définir les positions d'indexation de tirette adaptées aux deux mouvements. Ainsi, un dispositif d'indexation de tirette présentant les mêmes composants peut équiper des mouvements ou des pièces d'horlogerie très différents.The solutions described above will be advantageously implemented, when it comes to building watch movements, to constituting caliber families, in order to use as much as possible the same components or assemblies for movements whose final presentation is modulated by adding elements specific to the desired complication. Thus, for example, a calendar movement and a time zone movement of the same family may share the same base movement and a pull-out indexing device having the same components, these components, in particular the indexing element, simply being configured differently to define the pull-out indexing positions adapted to the two movements. Thus, a pull-out indexing device having the same components can equip very different movements or watch parts.

En particulier, les solutions décrites permettent de réaliser un dispositif de tirette configurable, qui permet notamment de mettre en oeuvre un mécanisme à deux ou trois positions selon le nombre de fonctions à corriger. Ces solutions permettent de maximiser le nombre de composants et d'assemblages communs aux mouvements d'une même famille.In particular, the solutions described make it possible to produce a configurable pull device, which in particular makes it possible to implement a two- or three-position mechanism depending on the number of functions to be corrected. These solutions make it possible to maximize the number of components and assemblies common to the movements of the same family.

Dans tout ce document, par « corps d'indexation », on entend de préférence un corps supportant un élément d'indexation, en particulier un corps supportant une came d'indexation.Throughout this document, by "indexing body" is preferably meant a body supporting an indexing element, in particular a body supporting an indexing cam.
