Description

La présente invention concerne de manière générale un dispositif d'arrêt pour un système oscillant d'un mouvement de montre, monté dans une montre, dans le domaine de l'horlogerie.The present invention relates generally to a stop device for an oscillating system of a watch movement, mounted in a watch, in the field of watchmaking.

Il est connu dans l'art antérieur des dispositifs d'arrêt de système oscillant, en particulier de balancier de montre. Le document EP1451647 décrit un dispositif d'arrêt de balancier comprenant un ressort à deux bras sensiblement en forme de V qui peut être appliqué sur un contour radialement périphérique du balancier.It is known in the prior art devices for stopping the oscillating system, in particular for a watch pendulum. The document EP1451647 describes a balance stop device comprising a spring with two arms substantially in the form of a V which can be applied to a radially peripheral contour of the balance.

En contrepartie, ce système présente notamment l'inconvénient de ne pas permettre d'arrêter ou de freiner un balancier sans serge de balancier (c'est-à-dire n'ayant pas de contour radialement périphérique). De plus, le dispositif d'arrêt entraîne l'application d'efforts sur le contour radialement périphérique, ce qui est dommageable pour le balancier, un arbre de balancier ou le montage de l'ensemble balancier et arbre dans le mouvement, perturbe le bon ajustement des jeux de fonctionnement et de géométrie, et provoque une usure prématurée des pièces du mouvement. Par ailleurs, l'arrêt du système oscillant est peu précis, lent et peu reproductible, à cause du glissement du ressort sur le contour radialement périphérique du balancier, et est encombrant.On the other hand, this system has the particular disadvantage of not making it possible to stop or brake a pendulum without the pendulum serge (that is to say having no radially peripheral contour). In addition, the stop device causes the application of forces on the radially peripheral contour, which is damaging for the balance, a balance shaft or the mounting of the balance and shaft assembly in movement, disturbs the good adjustment of the operating and geometry clearances, and causes premature wear of the movement parts. Furthermore, stopping the oscillating system is imprecise, slow and not very reproducible, due to the sliding of the spring on the radially peripheral contour of the balance, and is bulky.

Un but de la présente invention est de répondre aux inconvénients du document de l'art antérieur mentionné ci-dessus et en particulier, tout d'abord, de proposer un dispositif d'arrêt de système oscillant rapide, précis et fiable, applicable tant pour un balancier pourvu d'un serge que pour un balancier sans serge, avec un encombrement réduit.An object of the present invention is to respond to the drawbacks of the document of the prior art mentioned above and in particular, first of all, to provide a device for stopping the oscillating system fast, precise and reliable, applicable both for a pendulum provided with a serge only for a pendulum without serge, with a reduced bulk.

Pour cela, un premier aspect de l'invention concerne un dispositif d'arrêt pour un système oscillant d'un mouvement de montre, le système oscillant comprenant :

  • un arbre de balancier,
  • un balancier monté sur l'arbre de balancier,
  • un spiral,
  • un double plateau avec au moins un grand plateau, monté sur l'arbre de balancier,
le dispositif d'arrêt comprenant :
  • au moins un levier de commande d'arrêt de balancier,
caractérisé en ce que le dispositif d'arrêt comprend en outre un organe de freinage relié au levier de commande d'arrêt et agencé pour freiner le double plateau en entrant en contact avec le grand plateau du double plateau.For this, a first aspect of the invention relates to a stop device for an oscillating system of a watch movement, the oscillating system comprising:
  • a pendulum shaft,
  • a pendulum mounted on the pendulum shaft,
  • a hairspring,
  • a double plate with at least one large plate, mounted on the balance shaft,
the stop device comprising:
  • at least one pendulum stop control lever,
characterized in that the stop device further comprises a braking member connected to the stop control lever and arranged to brake the double plate by coming into contact with the large plate of the double plate.

Il est entendu que le double plateau comprend au moins un grand plateau et au moins un petit plateau. De plus, l'organe de freinage ou frein présente au moins deux positions, une première position dans laquelle le frein est à distance du grand plateau du double plateau et une deuxième position dans laquelle le frein est en contact avec le grand plateau du double plateau, de sorte à le freiner et l'arrêter.It is understood that the double tray comprises at least one large tray and at least one small tray. In addition, the braking or brake member has at least two positions, a first position in which the brake is at a distance from the large plate of the double plate and a second position in which the brake is in contact with the large plate of the double plate. , so as to brake and stop it.

Ceci permet de proposer un dispositif d'arrêt pour un système oscillant rapide, précis, fiable, évitant les à-coups, les glissements ou les coincements. De plus, comme l'application de l'effort de freinage n'est pas faite sur un contour radialement périphérique du balancier, le dispositif d'arrêt convient tant pour un balancier avec serge de balancier que pour un balancier sans serge de balancier. Plus encore, le dispositif réduit les contraintes mécaniques sur le balancier, sur l'arbre de balancier et sur les pièces du mouvement y afférentes, de sorte à garantir un bon comportement dans le temps et une conservation des performances sur le long terme. En outre, ceci permet de proposer un dispositif d'arrêt d'encombrement réduit.This makes it possible to propose a stop device for a rapid, precise, reliable oscillating system, avoiding jolts, slipping or jamming. In addition, since the application of the braking force is not made on a radially peripheral contour of the pendulum, the stop device is suitable both for a pendulum with balance rod and for a balance without balance rod. Furthermore, the device reduces the mechanical stresses on the balance wheel, on the balance shaft and on the associated movement parts, so as to guarantee good behavior over time and performance preservation over the long term. In addition, this makes it possible to propose a device for stopping reduced overall dimensions.

Avantageusement, l'arbre de balancier présente un axe de rotation, et l'organe de freinage est mobile en translation selon une direction parallèle à l'axe de rotation de l'arbre de balancier.Advantageously, the balance shaft has an axis of rotation, and the braking member is movable in translation in a direction parallel to the axis of rotation of the balance shaft.

Ceci permet de proposer un dispositif d'arrêt de système oscillant avec une grande précision et une application des efforts sans parasitage latéral, de sorte à assurer un freinage efficace et rapide, tout en préservant les pièces du mouvement d'efforts indus entraînant leur détérioration ou un jeu d'usure dégradant la précision du système oscillant.This makes it possible to propose a device for stopping the oscillating system with great precision and an application of the forces without lateral interference, so as to ensure efficient and rapid braking, while preserving the parts from the movement of undue forces causing their deterioration or wear and tear degrading the precision of the oscillating system.

Avantageusement, l'organe de freinage comprend au moins une portion d'anneau agencée pour entrer en contact avec le grand plateau.Advantageously, the braking member comprises at least one portion of a ring arranged to come into contact with the large plate.

Ceci permet de proposer un dispositif d'arrêt avec une bonne répartition des efforts de l'organe de freinage sur la pièce à freiner, de sorte à permettre un freinage efficace, précis et rapide.This makes it possible to propose a stop device with a good distribution of the forces of the braking member on the part to be braked, so as to allow efficient, precise and rapid braking.

Avantageusement, la portion d'anneau de l'organe de freinage comprend au moins deux portions de freinage agencées à 180° l'une de l'autre par rapport à l'arbre de balancier. Cela limite les couples de renversement sur l'arbre de balancier.Advantageously, the ring portion of the braking member comprises at least two braking portions arranged at 180 ° from one another relative to the balance shaft. This limits the overturning torques on the balance shaft.

Avantageusement, le double plateau comprend en outre un petit plateau, et un diamètre extérieur du grand plateau est plus grand qu'un diamètre extérieur du petit plateau.Advantageously, the double tray further comprises a small tray, and an outside diameter of the large tray is larger than an outside diameter of the small tray.

La figure 1 représente un dispositif d'arrêt pour un système oscillant d'un mouvement de montre selon la présente invention, dans une position à l'arrêt.The figure 1 shows a stop device for an oscillating system of a watch movement according to the present invention, in a stopped position.

En figure 1, le dispositif d'arrêt 100 est représenté dans une position dans laquelle il freine ou arrête le système oscillant 200, et est une vue en coupe C-C de la figure 7.In figure 1 , the stop device 100 is shown in a position in which it brakes or stops the oscillating system 200, and is a sectional view CC of the figure 7 .

Le système oscillant 200 comprend un arbre de balancier 9, un balancier 9.1 monté sur l'arbre de balancier 9, un spiral 9.5 non représenté ici pour des raisons de clarté de la figure (mais représenté en figure 9) coopérant avec le balancier 9.1 et permettant l'oscillation selon un principe bien connu en horlogerie. Le système oscillant 200 comprend en outre un double plateau 8 avec au moins un grand plateau 8.1 et un petit plateau 8.2, monté sur l'arbre de balancier 9. Le diamètre du grand plateau 8.1 est au moins deux fois, préférentiellement trois fois, très préférentiellement quatre fois le diamètre du petit plateau 8.2.The oscillating system 200 comprises a balance shaft 9, a balance 9.1 mounted on the balance shaft 9, a hairspring 9.5 not shown here for the sake of clarity in the figure (but shown in figure 9 ) cooperating with the pendulum 9.1 and allowing oscillation according to a principle well known in watchmaking. The oscillating system 200 further comprises a double plate 8 with at least one large plate 8.1 and a small plate 8.2, mounted on the balance shaft 9. The diameter of the large plate 8.1 is at least twice, preferably three times, very preferably four times the diameter of the small plate 8.2.

Le balancier 9.1 comprend au moins une masse d'équilibrage 9.2 et au moins une vis d'équilibrage 9.3, de sorte à assurer le bon équilibrage du balancier 9.1, et d'une manière plus globale, le bon équilibrage du système oscillant 200.The pendulum 9.1 comprises at least one balancing mass 9.2 and at least one balancing screw 9.3, so as to ensure proper balancing of the pendulum 9.1, and more generally, the proper balancing of the oscillating system 200.

Le dispositif d'arrêt 100 comprend au moins un levier de commande d'arrêt 6 et un organe de freinage 7 relié au levier de commande d'arrêt 6, et agencé pour freiner le double plateau 8 en entrant en contact avec le grand plateau 8.1 du double plateau 8.The stop device 100 comprises at least one stop control lever 6 and a braking member 7 connected to the stop control lever 6, and arranged to brake the double plate 8 by coming into contact with the large plate 8.1 of the double plate 8.

L'organe de freinage 7 comprend au moins une première portion d'anneau 7.4 agencée pour entrer en contact avec le grand plateau 8.1 du double plateau 8, un deuxième anneau 7.1 et au moins un arbre de liaison 7.3 agencé pour rendre solidaire la première portion d'anneau 7.4 et le deuxième anneau 7.1 et pour être en liaison glissière avec une base de cage 20 du mouvement de montre 301, la première portion d'anneau 7.4 et le deuxième anneau 7.1 étant situé de part et d'autre de la base de cage 20.The braking member 7 comprises at least a first portion of ring 7.4 arranged to come into contact with the large plate 8.1 of the double plate 8, a second ring 7.1 and at least one connecting shaft 7.3 arranged to make the first portion integral ring 7.4 and the second ring 7.1 and to be in sliding connection with a cage base 20 of the watch movement 301, the first portion of ring 7.4 and the second ring 7.1 being located on either side of the base cage 20.

La première portion d'anneau 7.4 est une partie d'anneau, lequel comprend un évidemment pour laisser le passage libre à un système d'échappement du mouvement de montre 301, coopérant avec le système oscillant 100, notamment le double plateau 8 et le balancier 9.1, laquelle coopération entre le système d'échappement et le système oscillant 200 est bien connue de l'homme du métier.The first ring portion 7.4 is a ring part, which includes a recess to allow free passage to an exhaust system of the watch movement 301, cooperating with the oscillating system 100, in particular the double plate 8 and the balance wheel 9.1, which cooperation between the exhaust system and the oscillating system 200 is well known to those skilled in the art.

Le deuxième anneau 7.1 est relié au levier de commande d'arrêt 6 afin de transmettre le mouvement de celui-ci. La liaison glissière entre l'arbre de liaison 7.3 et la base de cage 20 assure un mouvement de l'organe de freinage 7 parallèlement à l'axe de rotation de l'arbre de balancier 9.The second ring 7.1 is connected to the stop control lever 6 in order to transmit the movement thereof. The sliding link between the connecting shaft 7.3 and the cage base 20 provides movement of the braking member 7 parallel to the axis of rotation of the balance shaft 9.

En figure 1, la première portion d'anneau 7.4 de l'organe de freinage 7 est représentée en contact avec le grand plateau 8.1 du double plateau 8. En d'autres termes, lorsque levier de commande d'arrêt 6 reçoit une commande de freinage ou d'arrêt de la part de l'utilisateur, le levier de commande d'arrêt 6 est actionné vers le deuxième anneau 7.1 de l'organe de freinage 7 (c'est-à-dire vers le haut de la figure 1 telle que représentée) et entraîne l'organe de freinage 7 en translation. La première portion d'anneau 7.4 suit alors cette translation et entre en contact avec le grand plateau 8.1 afin de le freiner et de l'arrêter, arrêtant ainsi l'arbre de balancier 9 et le balancier 9.1.In figure 1 , the first ring portion 7.4 of the braking member 7 is shown in contact with the large plate 8.1 of the double plate 8. In other words, when the stop control lever 6 receives a brake command or d stop by the user, the stop control lever 6 is actuated towards the second ring 7.1 of the braking member 7 (that is to say towards the top of the figure 1 as shown) and drives the braking member 7 in translation. The first portion of ring 7.4 then follows this translation and comes into contact with the large plate 8.1 in order to brake and stop it, thus stopping the balance shaft 9 and the balance wheel 9.1.

Le mouvement de freinage en translation est transmis à l'arbre de balancier 9 qui vient en butée sur le pont supérieur de cage 10. Dans le présent mode de réalisation, le pont supérieur de cage 10 fait également office de porte-piton coopérant avec le spiral 9.5. L'arbre de balancier 9 comprend en outre une extrémité d'arbre de balancier 9.4 agencée pour être reçu ou logée par un amortisseur de choc 11, tel qu'un dispositif amortisseur de choc disponible dans le commerce, par exemple auprès de la société Incabloc, et tel qu'il sera décrit en figures 3 et 4, représentant un agrandissement de la zone D des figures 1 et 2.The translational braking movement is transmitted to the balance shaft 9 which abuts on the upper cage bridge 10. In the present embodiment, the upper cage bridge 10 also acts as a piton holder cooperating with the hairspring 9.5. The balance shaft 9 further comprises a balance shaft end 9.4 arranged to be received or housed by a shock absorber 11, such as a shock absorbing device available commercially, for example from the company Incabloc , and as it will be described in figures 3 and 4 , representing an enlargement of zone D of Figures 1 and 2 .

L'organe de freinage 7 comprend en outre un ressort de rappel 7.2 agencé pour rappeler l'organe de freinage 7. Le ressort de rappel 7.2 est relié à une première extrémité au deuxième anneau 7.1 et à une second extrémité à la base de cage 20. Le ressort 7.2 permet de rappeler l'organe de freinage 7 mais également d'éviter un freinage intempestif du balancier 9.1 en cas de choc ou de porté sportif de la montre, afin d'éviter toute dérive de l'indication temporelle de la montre et de la course des aiguilles.The braking member 7 further comprises a return spring 7.2 arranged to return the braking member 7. The return spring 7.2 is connected at one end to the second ring 7.1 and to a second end at the base of the cage 20 The spring 7.2 makes it possible to recall the braking member 7 but also to avoid inadvertent braking of the balance wheel 9.1 in the event of an impact or sporty wear of the watch, in order to avoid any drift in the time indication of the watch and needle stroke.

La figure 2 représente le dispositif d'arrêt de la figure 1, dans une position libre, c'est-à-dire sans freinage,The figure 2 represents the device for stopping the figure 1 , in a free position, that is to say without braking,

Le mode de réalisation de la figure 2 étant le même que celui de la figure 1, l'ensemble des éléments et signes de référence sont repris.The embodiment of the figure 2 being the same as that of the figure 1 , all the elements and reference signs are included.

Toutefois, la figure 2 se distingue de la figure 1 en ce qu'elle illustre l'organe de freinage 7 dans une position libre, c'est-à-dire sans freinage.However, the figure 2 stands out from the figure 1 in that it illustrates the braking member 7 in a free position, that is to say without braking.

La première portion d'anneau 7.4 n'est pas en contact avec le grand plateau 8.1 du double plateau 8. Il ne freine ni n'arrête donc pas le système oscillant 200, et le balancier 9.1 et l'arbre de balancier 9 sont ainsi libres de poursuivre leurs rotations périodiques.The first portion of ring 7.4 is not in contact with the large plate 8.1 of the double plate 8. It therefore does not brake or stop not the oscillating system 200, and the balance wheel 9.1 and the balance shaft 9 are thus free to continue their periodic rotations.

Le levier de commande d'arrêt 6 est tenu à distance du deuxième anneau 7.1 afin de pas freiner le système oscillant 200. Le ressort de rappel 7.2 assure le maintien du deuxième anneau 7.1, permettant ainsi d'éviter tout contact de l'organe de freinage 7 avec le grand plateau 8.1 du double plateau 8, notamment en cas de choc ou de porté sportif de la montre.The stop control lever 6 is held at a distance from the second ring 7.1 so as not to brake the oscillating system 200. The return spring 7.2 ensures the maintenance of the second ring 7.1, thus making it possible to avoid any contact with the braking 7 with the large plate 8.1 of the double plate 8, in particular in the event of an impact or sporty wearing of the watch.

La figure 3 représente un agrandissement du dispositif d'arrêt 100 selon la présente invention au niveau de l'extrémité de l'arbre de balancier 9.4, dans la position d'arrêt.The figure 3 shows an enlargement of the stop device 100 according to the present invention at the end of the balance shaft 9.4, in the stop position.

La figure 3 reprend le même mode de réalisation que la figure 1, dans la même position d'arrêt.The figure 3 uses the same embodiment as the figure 1 , in the same stop position.

L'amortisseur de choc 11 comprend au moins une cheminée 11.1, au moins un chaton 11.5, au moins un rubis 11.3 placé ou logé dans le chaton 11.5 ou porté par celui-ci, au moins un contre-pivot 11.4 et au moins un ressort d'amortissement 11.2.The shock absorber 11 comprises at least one chimney 11.1, at least one kitten 11.5, at least one ruby 11.3 placed, housed in or carried by the kitten 11.5, at least one counter-pivot 11.4 and at least one spring depreciation 11.2.

On entend par cheminée 11.1 un trou de guidage et/ou de passage dans l'amortisseur de choc 11 et une partie d'arrêt de l'amortisseur de choc 11 agencée en regard d'une portion de butée de l'extrémité de l'arbre de balancier 9.4.By chimney 11.1 is meant a guide and / or passage hole in the shock absorber 11 and a stop part of the shock absorber 11 arranged opposite a stop portion of the end of the balance shaft 9.4.

En figure 3, l'extrémité de l'arbre 9.4 est représentée en butée contre la cheminée 11.1, assurant ainsi le freinage et/ou l'arrêt de l'arbre de balancier 9. Il existe un jeu de fonctionnement entre l'extrémité de l'arbre 9.4 et le contre-pivot 11.4 de sorte à ne pas endommager l'extrémité de l'arbre de balancier 9.4.In figure 3 , the end of the shaft 9.4 is shown in abutment against the chimney 11.1, thus ensuring braking and / or stopping of the balance shaft 9. There is a clearance between the end of the shaft 9.4 and the counter-pivot 11.4 so as not to damage the end of the balance shaft 9.4.

Le ressort 11.2 permet de retenir le contre-pivot 11.4 en cas de choc et le rubis 11.3 guide l'extrémité de l'arbre de balancier 9.4 afin d'assurer un guidage avec le minimum de frottement possible.The spring 11.2 makes it possible to retain the counter-pivot 11.4 in the event of an impact and the ruby 11.3 guides the end of the balance shaft 9.4 in order to ensure guidance with the minimum possible friction.

La figure 4 représente l'agrandissement du dispositif d'arrêt 100 selon la présente invention au niveau de l'extrémité de l'arbre de balancier 9.4, dans la position libre.The figure 4 shows the enlargement of the stop device 100 according to the present invention at the end of the balance shaft 9.4, in the free position.

La figure 4 reprend le même mode de réalisation que la figure 2, dans la même position libre. Elle illustre la différence de position avec la figure 3.The figure 4 uses the same embodiment as the figure 2 , in the same free position. It illustrates the difference in position with the figure 3 .

La figure 4 montre un jeu prédéterminé 11.7 entre la partie d'arrêt de la cheminée 11.1 et la portion de butée 9.4. Ce jeu prédéterminé 11.7 est typiquement de l'ordre de 5/100e mm, et est inférieur à la course admissible de l'amortisseur de choc 11.The figure 4 shows a predetermined clearance 11.7 between the stop part of the chimney 11.1 and the stop portion 9.4. This predetermined clearance 11.7 is typically of the order of 5 / 100th mm, and is less than the admissible stroke of the shock absorber 11.

La course admissible de l'amortisseur de choc 11 est la course disponible avant l'ouverture du ressort d'amortissement 11.2, entre le rubis 11.3 et le contre-pivot 11.4, typiquement de l'ordre de 8/100e mm.The admissible stroke of the shock absorber 11 is the stroke available before the opening of the damping spring 11.2, between the ruby 11.3 and the counter-pivot 11.4, typically of the order of 8 / 100th mm.

La figure 5 représente le mouvement de montre selon la présente invention, dans la position à l'arrêt, vu en élévation.The figure 5 represents the watch movement according to the present invention, in the stopped position, seen in elevation.

La figure 5 reprend le même mode de réalisation que la figure 1, dans la position d'arrêt, l'ensemble des signes de référence restant identique.The figure 5 uses the same embodiment as the figure 1 , in the stop position, all the reference signs remaining identical.

La figure 6 reprend le même mode de réalisation que la figure 2, dans la position libre, l'ensemble des signes de référence restant identique.The figure 6 uses the same embodiment as the figure 2 , in the free position, all the reference signs remaining identical.

Le mouvement de montre 301 comprend en outre une bascule de levier 5 agencée pour coopérer avec le levier de commande 6 et une tige de remontoir 1 reliée à une couronne de remontoir 305 schématiquement représentée et opérable par l'utilisateur de la montre, et représentée schématiquement en figure 11.The watch movement 301 further comprises a lever rocker 5 arranged to cooperate with the control lever 6 and a winding rod 1 connected to a winding crown 305 schematically represented and operable by the user of the watch, and represented schematically in figure 11 .

Le mouvement comprend en outre une tirette 2, une bascule de tirette 3, un ressort de tirette 3.1 et un pignon coulant 4.The movement further includes a pull tab 2, a pull tab rocker, a pull spring 3.1 and a sliding pinion 4.

La tige de remontoir 1 coopère avec le levier de commande 6 par l'intermédiaire de la bascule de levier 5, de la tirette 2, de la bascule de tirette 3, du ressort de tirette 3.1 et du pignon coulant 4.The winding stem 1 cooperates with the control lever 6 by means of the lever rocker 5, the pull tab 2, the pull lever rocker 3, the pull spring 3.1 and the sliding pinion 4.

La tige de remontoir 1 présente ainsi une première position, dite position d'arrêt, dans laquelle elle permet d'actionner le levier de commande 6 et d'arrêter l'arbre de balancier 9 par l'intermédiaire de l'organe de freinage 7, comme représenté en figure 5.The winding stem 1 thus has a first position, called the stop position, in which it makes it possible to actuate the control lever 6 and to stop the balance shaft 9 by means of the braking member 7 , as shown in figure 5 .

La tige de remontoir 1 présente une deuxième position, dite position libre, dans laquelle elle laisse libre d'osciller l'arbre de balancier 9, en laissant l'organe de freinage 7 à distance du grand plateau 8.1 du double plateau 8, comme représenté en figure 6.The winding stem 1 has a second position, called the free position, in which it leaves free to oscillate the balance shaft 9, leaving the braking member 7 at a distance from the large plate 8.1 from the double plate 8, as shown in figure 6 .

Le mouvement comprend également un pont de bascule de levier 30 permettant le supportage et le pivotement de la bascule de levier 5.The movement also includes a lever rocker bridge 30 allowing the support and pivoting of the lever rocker 5.

La figure 7 reprend le même mode de réalisation que la figure 1, dans la position d'arrêt, l'ensemble des signes de référence restant identiques.The figure 7 uses the same embodiment as the figure 1 , in the stop position, all the reference signs remaining identical.

La figure 8 reprend le même mode de réalisation que la figure 2, dans la position libre, l'ensemble des signes de référence restant identique.The figure 8 uses the same embodiment as the figure 2 , in the free position, all the reference signs remaining identical.

En figure 7, la tige de remontoir 1 est dans la position d'arrêt, et détermine une position dite d'arrêt du pignon 4 le long d'un axe de la tige de remontoir 1. La bascule de levier 5 est donc pivotée suivant un premier angle correspondant à la position d'arrêt de la tige de remontoir 1. La bascule de levier 5 comprend deux bras répartis de part et d'autre d'un pivot 30.1 du pont de bascule de levier 30. Dans cette première position, le premier bras de la bascule de levier 5 est en prise avec le pignon coulant 4 et le deuxième bras de la bascule de levier 5 est en contact avec une portion de came 6.1 du levier de commande 6. Le premier bras de la bascule de levier 5 présente de préférence une longueur égale au tiers de la longueur du deuxième bras de la bascule de levier 5.In figure 7 , the winding stem 1 is in the stop position, and determines a so-called stop position of the pinion 4 along an axis of the winding stem 1. The lever rocker 5 is therefore pivoted at a first angle corresponding to the stop position of the winding stem 1. The lever lever 5 comprises two arms distributed on either side of a pivot 30.1 of the lever lever bridge 30. In this first position, the first arm of the lever lever 5 is engaged with the sliding pinion 4 and the second arm of the lever lever 5 is in contact with a cam portion 6.1 of the control lever 6. The first arm of the lever lever 5 preferably has a length equal to one third of the length of the second arm of the lever lever 5.

Le levier de commande 6 comprend en outre une extrémité d'attache 6.2, fixée à une platine fixe solidaire du boîtier de la montre 300 représentée schématiquement en figure 11, et une extrémité mobile agencée pour entrer en contact avec l'organe de freinage 7.The control lever 6 further comprises an attachment end 6.2, fixed to a fixed plate integral with the watch case 300 shown diagrammatically in figure 11 , and a movable end arranged to come into contact with the braking member 7.

La portion de came 6.1 du levier de commande 6 permet de transformer le mouvement de la bascule de levier 5 dans un plan en un mouvement dans un autre plan du levier de commande 6. En d'autres termes, une portion bizautée de la portion de came 6.1 permet de faire pivoter l'extrémité mobile du levier de commande 6 lorsqu'elle entre en contact avec la bascule de levier 5.The cam portion 6.1 of the control lever 6 makes it possible to transform the movement of the lever rocker 5 in one plane into a movement in another plane of the control lever 6. In other words, a curved portion of the portion of cam 6.1 allows the movable end of the control lever 6 to be pivoted when it comes into contact with the lever lever 5.

La portion de came 6.1 est située entre l'extrémité d'attache et l'extrémité mobile, à une distance au moins égale à un tiers d'une longueur mobile du levier de commande 6, comptée depuis l'extrémité d'attache.The cam portion 6.1 is located between the attachment end and the movable end, at a distance at least equal to one third of a movable length of the control lever 6, counted from the attachment end.

En figure 8, la tige de remontoir 1 est dans la position libre, et détermine la position dite libre du pignon coulant 4 le long de l'axe de la tige de remontoir 1. Dans cette position libre, la bascule de levier 5 est pivotée d'un deuxième angle autour de son axe de rotation du pivot 30.1 du pont de bascule de levier 30. Le deuxième bras de la bascule de levier 5 est positionné à distance de la portion de came 6.1 du levier de commande 6 et donc le levier de commande 6 n'entre pas en contact avec l'organe de freinage 7, laissant l'oscillation libre pour le balancier 9.1 et l'arbre de balancier 9.In figure 8 , the winding stem 1 is in the free position, and determines the so-called free position of the sliding pinion 4 along the axis of the winding stem 1. In this free position, the lever rocker 5 is pivoted by a second angle around its axis of rotation of the pivot 30.1 of the lever rocker bridge 30. The second arm of the lever rocker 5 is positioned at a distance from the cam portion 6.1 of the control lever 6 and therefore the control lever 6 does not come into contact with the braking member 7, leaving free oscillation for the balance wheel 9.1 and the balance shaft 9.

Le ressort de tirette 3.1 permet le rappel de la tirette 2.The pull tab spring 3.1 allows the pull back of the pull tab 2.

La figure 9 représente le mouvement de montre avec le boitier de montre selon la présente invention, dans une position libre, c'est-à-dire sans freinage, vu en élévation.
