Description

Domaine technique de l'inventionTechnical field of the invention

L'invention relève du domaine de l'horlogerie, et notamment des mouvements horlogers.The invention relates to the field of watchmaking, and in particular watch movements.

Plus particulièrement, l'invention concerne un mouvement horloger comportant une fonction « stop seconde » actionnable à partir de deux organes de commande distincts.More particularly, the invention relates to a watch movement comprising a “stop seconds” function operable from two separate control members.

Arrière-plan technologiqueTechnology background

La fonction « stop seconde » est une complication horlogère bien connue et permet d'immobiliser l'afficheur des secondes afin de pouvoir mettre à l'heure une montre de façon plus précise.The “stop seconds” function is a well-known horological complication and makes it possible to immobilize the seconds display in order to be able to set the time of a watch more precisely.

Cette fonction est mise en œuvre par l'immobilisation du régulateur de la montre par un mécanisme d'arrêt adapté, suite à la sollicitation par un utilisateur d'une couronne de la montre. Une fois la montre mise à l'heure, le régulateur est libéré, par une autre sollicitation de la couronne.This function is implemented by the immobilization of the regulator of the watch by a suitable stop mechanism, following the request by a user of a crown of the watch. Once the watch has been set, the regulator is released by pressing the crown again.

Dans certains mouvements horlogers de l'état de la technique, la fonction « stop seconde » est associée à une mise à une position de référence de l'afficheur des secondes, la position de référence correspondant généralement à la position zéro, c'est-à-dire 12h00.In certain state-of-the-art watch movements, the "stop seconds" function is associated with setting the seconds display to a reference position, the reference position generally corresponding to the zero position, i.e. i.e. 12:00 p.m.

L'association de ces fonctions permet de mettre à l'heure encore plus précisément la montre.The combination of these functions makes it possible to set the time even more precisely.

Il existe toutefois un besoin, pour certaines applications, non couvert par les dispositifs de l'état de la technique, consistant à disposer d'une montre dont les fonctions stop seconde et de remise à zéro de l'afficheur des secondes puissent être mise en œuvre par des moyens distincts, et ce dans une conception la plus simple possible.There is however a need, for certain applications, not covered by the devices of the state of the art, consisting in having a watch whose stop-seconds and reset-to-zero functions the seconds display can be implemented by separate means, and this in the simplest possible design.

Résumé de l'inventionSummary of the invention

L'invention résout les inconvénients précités.The invention solves the aforementioned drawbacks.

À cet effet, la présente invention concerne un mouvement horloger comprenant un mobile d'un afficheur d'une valeur temporelle, tel qu'un mobile des secondes, une source d'énergie reliée à ce mobile d'un afficheur pour l'entraîner en rotation, et un régulateur destiné à réguler le mouvement de ce mobile d'un afficheur, ledit mouvement horloger comprenant un mécanisme de contrôle adapté à occuper un état actif dans lequel il coopère avec le régulateur pour l'immobiliser, et un état inactif dans lequel il libère le régulateur de sorte que ce dernier soit apte à régulariser le mouvement du mobile d'un afficheur d'une valeur temporelle.To this end, the present invention relates to a horological movement comprising a moving part of a display of a time value, such as a seconds moving part, an energy source connected to this moving part of a display to drive it in rotation, and a regulator intended to regulate the movement of this moving part of a display, said watch movement comprising a control mechanism adapted to occupy an active state in which it cooperates with the regulator to immobilize it, and an inactive state in which it releases the regulator so that the latter is capable of regulating the movement of the mobile of a display of a time value.

Le mécanisme de contrôle comporte deux modules de transmission de mouvement chacun destiné à être relié à un organe de commande propre, chacun desdits modules étant configuré pour entraîner le mécanisme de contrôle entre son état inactif et son état actif sur sollicitation de l'organe de commande auquel il est relié.The control mechanism comprises two motion transmission modules each intended to be connected to its own control member, each of said modules being configured to drive the control mechanism between its inactive state and its active state on request from the control member to which it is connected.

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 also include one or more of the following characteristics, taken separately or in all technically possible combinations.

Dans des modes particuliers de réalisation, le mécanisme de contrôle est adapté à occuper un état actif dans lequel il coopère avec le mobile d'un afficheur d'une valeur temporelle pour l'entraîner en rotation dans une position prédéfinie, et un état inactif dans lequel il libère le mobile d'un afficheur d'une valeur temporelle de sorte à autoriser son déplacement.In particular embodiments, the control mechanism is suitable for occupying an active state in which it cooperates with the mobile of a display of a time value to drive it in rotation in a predefined position, and an inactive state in which it releases the mobile from a display of a time value so as to authorize its movement.

Dans des modes particuliers de réalisation, le mécanisme de contrôle comporte :

  • un levier stop agencé mobile en rotation et occupant une position active dans laquelle il repose en appui contre le régulateur lorsque le mécanisme de contrôle occupe l'état actif ;
  • une bascule de transmission portant une bascule satellite configurée de sorte à relier les modules de transmission avec le levier stop et à occuper une position active, lorsque le mécanisme de contrôle occupe l'état actif, dans laquelle ladite bascule satellite entraîne ledit levier stop dans sa position active.
In particular embodiments, the control mechanism comprises:
  • a stop lever arranged to move in rotation and occupying an active position in which it bears against the regulator when the control mechanism occupies the active state;
  • a transmission latch carrying a satellite latch configured so as to connect the transmission modules with the stop lever and to occupy an active position, when the control mechanism occupies the active state, in which said satellite latch drives said stop lever in its active position.

Dans des modes particuliers de réalisation, le mécanisme de contrôle comporte un marteau agencé mobile en rotation, la bascule satellite étant configurée de sorte à relier les modules de transmission et le marteau de sorte que ledit marteau occupe une position active dans laquelle il repose en appui contre une came cœur solidaire du mobile d'un afficheur d'une valeur temporelle lorsque la bascule satellite occupe la position active.In particular embodiments, the control mechanism comprises a hammer arranged mobile in rotation, the satellite rocker being configured so as to connect the transmission modules and the hammer so that said hammer occupies an active position in which it rests against a heart cam secured to the moving part of a display of a time value when the satellite flip-flop occupies the active position.

Dans des modes particuliers de réalisation, le levier stop, le marteau et la bascule de transmission sont mobiles en rotation autour d'un même axe de rotation.In particular embodiments, the stop lever, the hammer and the transmission rocker are rotatable around the same axis of rotation.

Description détaillée de l'inventionDetailed description of the invention

La présente invention concerne une montre 10 comprenant un mouvement horloger doté d'une fonction « stop seconde » tel que schématiquement représenté sur la figure 1. Il y a lieu de noter que la montre 10, dans une application préférée de la présente invention, est une montre sympathique destinée à coopérer avec une pendule sympathique.The present invention relates to a watch 10 comprising a watch movement provided with a “stop seconds” function as shown schematically in the figure 1 . It should be noted that the watch 10, in a preferred application of the present invention, is a sympathetic watch intended to cooperate with a sympathetic clock.

Le mouvement horloger selon la présente invention comprend un mobile d'un afficheur d'une valeur temporelle, tel qu'un mobile des secondes, destiné à porter un afficheur des secondes 11, tel qu'une aiguille des secondes.The horological movement according to the present invention comprises a wheel set for a time value display, such as a seconds wheel set, intended to carry a seconds display 11, such as a seconds hand.

Le mouvement horloger comprend, en outre, une source d'énergie, tel qu'un barillet 12, reliée au mobile des secondes pour l'entraîner en rotation, de façon connue par l'homme du métier, et un régulateur 13 destiné à réguler le mouvement du mobile des secondes, comme visible sur la figure 1.The watch movement further comprises an energy source, such as a barrel 12, connected to the seconds wheel to drive it in rotation, in a manner known to those skilled in the art, and a regulator 13 intended to regulate the movement of the seconds wheel, as seen on the figure 1 .

Le mouvement horloger comprend également un mécanisme de contrôle 20, tel qu'illustré sur les figures 2 à 6, adapté à occuper un état actif dans lequel il coopère, d'une part, avec le régulateur 13 pour l'immobiliser, et d'autre part, avec le mobile des secondes pour l'entraîner en rotation dans une position prédéfinie. Le mécanisme de contrôle 20 est par ailleurs adapté à occuper un état inactif dans lequel il libère, d'une part, le régulateur 13 de sorte que ce dernier soit apte à régulariser le mouvement du mobile des secondes, et d'autre part, le mobile des secondes de sorte à autoriser son déplacement.The watch movement also includes a control mechanism 20, as illustrated in the figures 2 to 6 , adapted to occupy an active state in which it cooperates, on the one hand, with the regulator 13 to immobilize it, and on the other hand, with the mobile of the seconds to drive it in rotation in a predefined position. The control mechanism 20 is also suitable for occupying an inactive state in which it releases, on the one hand, the regulator 13 so that the latter is capable of regulating the movement of the seconds mobile, and on the other hand, the mobile seconds so as to authorize its movement.

Avantageusement, le mécanisme de contrôle 20 comporte deux modules de transmission de mouvement chacun destiné à être relié à un organe de commande propre, lesdits modules de transmission étant l'un et l'autre configurés pour entraîner le mécanisme de contrôle 20 entre son état inactif et son état actif, sur sollicitation de l'organe de commande auquel ils sont reliés.Advantageously, the control mechanism 20 comprises two motion transmission modules each intended to be connected to its own control member, said transmission modules being both configured to drive the control mechanism 20 between its inactive state and its active state, upon request from the control device to which they are connected.

Plus particulièrement, le mécanisme de contrôle 20 comporte un levier stop 21 agencé de façon mobile en rotation et occupant une position active dans laquelle il repose en appui contre le régulateur 13 lorsque le mécanisme de contrôle 20 occupe l'état actif. Plus précisément, comme le montrent les figures 1 à 6, le levier stop 21 comprend un bras d'appui 210 destiné à reposer en appui par son extrémité libre contre un balancier du régulateur 13, et un bras de transmission 211 destiné à recevoir des efforts entraînant le déplacement du levier stop 21.More particularly, the control mechanism 20 comprises a stop lever 21 arranged in a rotatable manner and occupying an active position in which it bears against the regulator 13 when the control mechanism 20 is in the active state. More specifically, as shown by the figures 1 to 6 , the stop lever 21 comprises a support arm 210 intended to bear by its free end against a balance of the regulator 13, and a transmission arm 211 intended to receive forces causing the movement of the stop lever 21.

Le mécanisme de contrôle 20 comporte également un marteau 22 agencé de manière mobile en rotation, et occupant une position active dans laquelle il repose en appui contre une came cœur 110 solidaire du mobile des secondes lorsque le mécanisme de contrôle 20 occupe l'état actif.The control mechanism 20 also comprises a hammer 22 arranged in a rotatable manner, and occupying an active position in which it rests against a heart cam 110 integral with the seconds wheel set when the control mechanism 20 is in the active state.

Par ailleurs, le mécanisme de contrôle 20 comprend une bascule de transmission 23 portant une bascule satellite 261 configurée de sorte à relier les modules de transmission avec le levier stop 21 et le marteau 22, et de sorte à occuper une position active lorsque le mécanisme de contrôle 20 occupe l'état actif dans laquelle ladite bascule entraîne ledit levier stop 21 et ledit marteau 22 dans leur position active. Autrement dit, lorsque l'un des organes de commande est sollicité, il entraîne le déplacement du module de transmission auquel il est relié, et l'entraînement du levier stop 21 et du marteau 22 par l'intermédiaire de la bascule de la bascule satellite 261.Furthermore, the control mechanism 20 comprises a transmission rocker 23 carrying a satellite rocker 261 configured so as to connect the transmission modules with the stop lever 21 and the hammer 22, and so as to occupy an active position when the mechanism of control 20 occupies the active state in which said rocker drives said stop lever 21 and said hammer 22 into their active position. In other words, when one of the control members is activated, it causes the movement of the transmission module to which it is connected, and the driving of the stop lever 21 and of the hammer 22 via the rocker of the satellite rocker. 261.

La bascule satellite 261 est fixée de manière mobile en rotation sur la bascule de transmission 23.The satellite rocker 261 is fixed in a rotatable manner on the transmission rocker 23.

Préférentiellement, tel que représenté sur les figures 1 à 6, le levier stop 21, le marteau 22 et la bascule de transmission 23 sont mobiles en rotation autour d'un même axe de rotation. Cette caractéristique permet avantageusement de simplifier le mécanisme de contrôle 20.Preferably, as represented on the figures 1 to 6 , the stop lever 21, the hammer 22 and the transmission rocker 23 are rotatable around the same axis of rotation. This characteristic advantageously makes it possible to simplify the control mechanism 20.

Le mécanisme de contrôle 20 comprend un ressort 24 permettant de contraindre le mécanisme de contrôle 20 vers son état actif. Plus précisément, le ressort 24 est configuré de sorte à solliciter le marteau 22 et le levier stop 21 vers leur position active respective, ces derniers étant agencés en butée contre un élément de retenu porté par la bascule satellite 261. Autrement dit, le ressort 24 applique un effort de rappel sur le marteau 22 qui le transmet au levier stop 21 et à la bascule de transmission 23 par le biais de l'élément de retenu.The control mechanism 20 comprises a spring 24 making it possible to force the control mechanism 20 towards its active state. More specifically, the spring 24 is configured so as to urge the hammer 22 and the stop lever 21 towards their respective active position, the latter being arranged in abutment against a retaining element carried by the satellite rocker 261. In other words, the spring 24 applies a return force to the hammer 22 which transmits it to the stop lever 21 and to the transmission lever 23 via the retaining element.

Par ailleurs, dans ces exemples de réalisation de l'invention, le marteau 22 est interposé entre le levier stop 21 et la bascule de transmission 23.Furthermore, in these embodiments of the invention, the hammer 22 is interposed between the stop lever 21 and the transmission rocker 23.

L'un des modules de transmission, dit « premier module de transmission », comporte un levier de transmission 25 s'étendant entre deux extrémités et étant relié à l'un des organes de commande, dit « premier organe de commande » au niveau d'un pivot 250 agencé entre lesdites extrémités. Il y a lieu de noter que les caractéristiques du premier module de transmission sont identiques dans les deux exemples de réalisation de l'invention représentés sur les figures.One of the transmission modules, called "first transmission module", comprises a transmission lever 25 extending between two ends and being connected to one of the control members, called "first control member" at the level of a pivot 250 arranged between said ends. It should be noted that the characteristics of the first transmission module are identical in the two exemplary embodiments of the invention shown in the figures.

Le premier organe de commande est préférentiellement formé par un actionneur de la montre 10, tel qu'un poussoir 14, adapté à coopérer avec un actionneur d'une pendule sympathique. Ces actionneurs ne sont pas décrits plus en détail dans le présent texte dans la mesure où ils ne constituent pas en tant que tels l'objet de la présente invention.The first control member is preferably formed by an actuator of the watch 10, such as a pusher 14, adapted to cooperate with an actuator of a sympathetic clock. These actuators are not described in more detail in this text insofar as they do not constitute as such the object of the present invention.

Le levier de transmission 25 est mobile en rotation au niveau d'une de ses extrémités et comprend à son autre extrémité une excroissance 251 par laquelle il coopère avec la bascule de transmission 23 de sorte à l'entraîner en rotation lorsqu'il est sollicité par le premier organe de commande. L'excroissance 251 peut prendre la forme d'un tenon et prend appui, comme l'illustrent les figures, sur l'un des bras, dit « premier bras » 230, de la bascule de transmission 23 de sorte à s'opposer à l'effort exercé par le ressort 24 tendant à entraîner ledit levier stop 21 et ledit marteau 22 dans leur position active.The transmission lever 25 is rotatable at one of its ends and comprises at its other end a protrusion 251 by which it cooperates with the transmission rocker 23 so as to drive it in rotation when it is urged by the first controller. The protrusion 251 can take the form of a tenon and rests, as shown in the figures, on one of the arms, called "first arm" 230, of the transmission rocker 23 so as to oppose the force exerted by the spring 24 tending to drive said stop lever 21 and said hammer 22 into their active position.

Dans les exemples de réalisation de l'invention représentés sur les figures, l'autre module de transmission, dit « second module de transmission », est agencé de façon opposé au premier module de transmission relativement à la bascule de transmission 23, au marteau 22 et au levier stop 21. Autrement dit, la bascule de transmission 23, le marteau 22 et le levier stop 21 sont interposés entre les deux modules de transmission.In the exemplary embodiments of the invention shown in the figures, the other transmission module, called "second transmission module", is arranged opposite to the first transmission module relative to the transmission rocker 23, to the hammer 22 and to the stop lever 21. In other words, the transmission rocker 23, the hammer 22 and the stop lever 21 are interposed between the two transmission modules.

Comme représenté sur les figures 3 et 5, le second module de transmission comporte une bascule de liaison 260 destinée à être reliée à l'un des organes de commande, dit « second organe de commande ». La bascule de liaison 260 et la bascule satellite 261 sont reliées l'une à l'autre par une bielle 262, ladite bielle 262 permettant de transmettre à la bascule satellite 261 un mouvement de la bascule de liaison 260 généré par la sollicitation du second organe de commande.As shown on the figure 3 And 5 , the second transmission module comprises a link rocker 260 intended to be connected to one of the control elements, called the “second control element”. There link rocker 260 and the satellite rocker 261 are connected to each other by a connecting rod 262, said connecting rod 262 making it possible to transmit to the satellite rocker 261 a movement of the connecting rocker 260 generated by the actuation of the second order.

Le second organe de commande est préférentiellement formé par une couronne 15 de la montre 10, destinée à être manipulée par l'utilisateur de ladite montre 10. De façon connue en soi, la couronne 15 peut être reliée par une tige mobile en translation à une tirette, non représentées sur les figures. La tirette est avantageusement configurée pour transmettre un mouvement de rotation à la bascule de liaison 260 suite à une translation de la couronne 15. Par exemple la tirette peut être reliée à la bascule de liaison 260 par un pivot.The second control member is preferably formed by a crown 15 of the watch 10, intended to be manipulated by the user of said watch 10. In a manner known per se, the crown 15 can be connected by a rod movable in translation to a pull tab, not shown in the figures. The pull tab is advantageously configured to transmit a rotational movement to the link rocker 260 following a translation of the crown 15. For example the pull tab can be connected to the link rocker 260 by a pivot.

La bascule satellite 261 est agencée pour coopérer avec le marteau 22 et le levier stop 21 de sorte que, lorsque le second organe de commande est sollicité pour entraîner le mécanisme de contrôle 20 dans son état inactif, elle s'oppose à l'effort exercé par le ressort 24 tendant à entraîner ledit levier stop 21 et ledit marteau 22 dans leur position inactive, et ce, sans provoquer la rotation de la bascule de transmission 23.The satellite rocker 261 is arranged to cooperate with the hammer 22 and the stop lever 21 so that, when the second control member is urged to drive the control mechanism 20 in its inactive state, it opposes the force exerted by the spring 24 tending to drive said stop lever 21 and said hammer 22 into their inactive position, and this, without causing the rotation of the transmission rocker 23.

A l'inverse, la bascule satellite 261 est agencée pour coopérer avec le marteau 22 et le levier stop 21 de sorte que, lorsque le second organe de commande est sollicité pour entraîner le mécanisme de contrôle 20 dans son état actif, elle permette la libération dudit levier stop 21 et dudit marteau 22 vers leur position active sous l'effet de l'effort exercé par le ressort 24, et ce, sans provoquer la rotation de la bascule de transmission 23.Conversely, the satellite rocker 261 is arranged to cooperate with the hammer 22 and the stop lever 21 so that, when the second control member is urged to drive the control mechanism 20 into its active state, it allows the release said stop lever 21 and said hammer 22 towards their active position under the effect of the force exerted by the spring 24, and this, without causing the rotation of the transmission rocker 23.

Plus précisément, dans les exemples de réalisation représentés sur les figures 2 à 6, la bascule satellite 261 est fixée de manière mobile en rotation, par exemple à la manière d'un mobile satellite, sur la bascule de transmission 23, et plus particulièrement sur un des bras de cette dernière dit « second bras » 231.More precisely, in the examples of embodiment represented on the figures 2 to 6 , the satellite rocker 261 is fixed in a rotatable manner, for example in the manner of a mobile satellite, on the transmission rocker 23, and more particularly on one of the arms of the latter called "second arm" 231.

En résumé, les deux modules de transmission sont liés au marteau 22 et au levier stop 21 par la bascule de transmission 23 et par la bascule satellite 261, par exemple à la manière d'un rouage différentiel.In summary, the two transmission modules are linked to the hammer 22 and to the stop lever 21 by the transmission rocker 23 and by the satellite rocker 261, for example in the manner of a differential gear train.

Avantageusement, comme l'illustrent les figures 3 et 5, la bielle 262 est articulée à une première aile 263 de la bascule satellite 261, ladite première aile 263 étant opposée à une seconde aile 264 comprenant l'élément de retenu contre lequel le marteau 22 et le levier stop 21 sont agencés en appui.Advantageously, as illustrated by the figure 3 And 5 , the connecting rod 262 is hinged to a first wing 263 of the satellite rocker 261, said first wing 263 being opposed to a second wing 264 comprising the retaining element against which the hammer 22 and the stop lever 21 are arranged in support.

On comprend ici que la sollicitation du levier de transmission 25 par le premier organe de commande, de sorte à libérer le mécanisme de contrôle 20 dans vers son état actif, libère ledit levier pour un déplacement angulaire dans un premier sens de rotation permettant la rotation de la bascule de transmission 23 sous l'effet de l'effort généré par le ressort 24, ledit effort étant transmis à ladite bascule de transmission 23 par l'appui du marteau 22 sur la seconde aile 264 de la bascule satellite 261.It is understood here that the actuation of the transmission lever 25 by the first control member, so as to release the control mechanism 20 into its active state, releases said lever for an angular displacement in a first direction of rotation allowing the rotation of the transmission rocker 23 under the effect of the force generated by the spring 24, said force being transmitted to the said transmission rocker 23 by the support of the hammer 22 on the second wing 264 of the satellite rocker 261.

En d'autres termes, le premier organe de commande est agencé de sorte à provoquer le pivotement de la bascule de transmission 23, alors que la bielle 262 et la bascule de liaison 260 sont immobiles, ce qui contraint la rotation de la bascule satellite 261 par rapport à l'extrémité de la bielle 262 à laquelle la première aile 263 est reliée, et entraine le marteau 22 et le levier stop 21 par le tenon 270.In other words, the first control member is arranged so as to cause the pivoting of the transmission rocker 23, while the connecting rod 262 and the connecting rocker 260 are stationary, which constrains the rotation of the satellite rocker 261 relative to the end of the connecting rod 262 to which the first wing 263 is connected, and causes the hammer 22 and the stop lever 21 by the tenon 270.

A l'inverse, la sollicitation du levier de transmission 25 par le premier organe de commande, de sorte à entraîner le mécanisme de contrôle 20 dans l'état inactif, contraint ledit levier à un déplacement angulaire dans un second sens de rotation ayant pour effet d'entraîner la rotation de la bascule de transmission 23 à l'encontre de l'effort généré par le ressort 24, ledit effort étant transmis à ladite bascule de transmission 23 par l'appui du marteau 22 sur la seconde aile 264 de la bascule satellite 261.Conversely, the actuation of the transmission lever 25 by the first control member, so as to drive the control mechanism 20 in the inactive state, forces said lever to an angular displacement in a second direction of rotation having the effect to cause the rotation of the transmission rocker 23 against the force generated by the spring 24, said force being transmitted to said transmission rocker 23 by the support of the hammer 22 on the second wing 264 of the rocker satellite 261.

Par ailleurs, la sollicitation de la bascule de liaison 260 par le second organe de commande, de sorte à entraîner le mécanisme de contrôle 20 dans l'état actif, libère le pivotement, par rapport à la bascule de transmission 23 et dans un premier sens de rotation, de la bascule satellite 261 par le biais de la bielle 262, permettant libérer la rotation du marteau 22 et du levier stop 21 sous l'effet de l'effort généré par le ressort 24.Furthermore, the actuation of the link rocker 260 by the second control member, so as to drive the control mechanism 20 in the active state, releases the pivoting, relative to the transmission rocker 23 and in a first direction of rotation, of the satellite rocker 261 by means of the connecting rod 262, allowing to release the rotation of the hammer 22 and of the lever stop 21 under the effect of the force generated by the spring 24.

En d'autres termes, le second organe de commande est agencé de sorte à provoquer le pivotement de la bascule de liaison 260, alors que le levier de transmission 25 et la bascule de transmission 23 sont immobiles, ce qui contraint la rotation de la bascule satellite 261 par rapport à la bascule de transmission 23 et entraine le marteau 22 et le levier stop 21 par le tenon 270.In other words, the second control member is arranged so as to cause the pivoting of the link rocker 260, while the transmission lever 25 and the transmission rocker 23 are stationary, which constrains the rotation of the rocker satellite 261 with respect to the transmission rocker 23 and drives the hammer 22 and the stop lever 21 by the tenon 270.

A l'inverse, la sollicitation de la bascule de liaison 260 par le second organe de commande, de sorte à entraîner le mécanisme de contrôle 20 dans l'état inactif, contraint le pivotement, par rapport à la bascule de transmission 23 et dans un second sens de rotation, de la bascule satellite 261 par le biais de la bielle 262, permettant d'entraîner la rotation du marteau 22 et du levier stop 21 à l'encontre de l'effort généré par le ressort 24.Conversely, the actuation of the link rocker 260 by the second control member, so as to drive the control mechanism 20 into the inactive state, constrains the pivoting, with respect to the transmission rocker 23 and in a second direction of rotation, of the satellite rocker 261 via the connecting rod 262, making it possible to drive the rotation of the hammer 22 and of the stop lever 21 against the force generated by the spring 24.

En particulier, dans l'exemple de réalisation représenté sur les figures 4 à 6, l'élément de retenu est formé par un tenon 270 s'étendant depuis une surface de la seconde aile 264 de la bascule satellite 261 et s'engageant dans une cavité 271 que comporte le bras de transmission 211 du levier stop 21.In particular, in the exemplary embodiment shown in the figures 4 to 6 , the retaining element is formed by a tenon 270 extending from a surface of the second wing 264 of the satellite rocker 261 and engaging in a cavity 271 that comprises the transmission arm 211 of the stop lever 21.

Plus précisément, comme le montre en détail la figure 6, dans cet exemple de réalisation, la cavité 271 est de forme oblongue de sorte à autoriser le coulissement du tenon 270 au sein de ladite cavité 271. Une telle translation est occasionnée par exemple lorsque la bascule satellite 261 est entraînée en rotation par rapport à la bascule de transmission 23, sous la sollicitation du second organe de commande.More specifically, as detailed in the figure 6 , in this exemplary embodiment, the cavity 271 is oblong in shape so as to allow the sliding of the tenon 270 within said cavity 271. Such a translation is caused for example when the satellite rocker 261 is rotated relative to the transmission rocker 23, under the influence of the second control member.

Il y a lieu de noter que la cavité, dans d'autres exemples de réalisation, peut être réalisée sur seconde aile 264 de la bascule satellite 261 et que le tenon 270 peut s'étendre depuis une surface du bras de transmission 211 du levier stop 21.It should be noted that the cavity, in other exemplary embodiments, can be made on the second wing 264 of the satellite rocker 261 and that the tenon 270 can extend from a surface of the transmission arm 211 of the stop lever 21.

De manière plus générale, il est à noter que les exemples de réalisation considérés ci-dessus ont été décrits à titre d'exemples non limitatifs, et que d'autres variantes sont par conséquent envisageables.More generally, it should be noted that the embodiments considered above have been described by way of non-limiting examples, and that other variants are therefore possible.

Notamment, le premier et le second organe de commande peuvent être formés par tout élément approprié, tel qu'une lunette, un poussoir, un levier, etc.In particular, the first and the second control member can be formed by any appropriate element, such as a bezel, a pusher, a lever, etc.
