Description
La présente invention est relative au domaine de l'horlogerie, plus particulièrement à un dispositif de remontage d'un ressort de barillet d'un mouvement horloger automatique comportant un système de débrayage.The present invention relates to the field of watchmaking, more particularly to a device for winding a mainspring of an automatic watch movement comprising a disengaging system.
Il existe déjà des dispositifs de remontage d'une montre automatique qui se distinguent des dispositifs traditionnels par les moyens techniques utilisés pour transmettre l'énergie cinétique de la masse automatique à la roue d'armage.
C487440 porte sur un dispositif horloger d'accouplement limiteur de couple pour deux éléments coaxiaux dont l'un des éléments présente, sur sa face tournée en regard de l'autre élément une noyure dans laquelle est logé au moins un ressort-fil engagé par ses extrémités dans des logements ménagés à cet effet dans la paroi latérale de ladite noyure, La portée cylindrique du second élément est située dans ladite noyure, le ressort prenant appui sur elle par sa partie centrale.C487440 relates to a clutch coupling torque limiting device for two coaxial elements, one of the elements of which has, on its facing face facing the other element, a hole in which is housed at least one wire spring engaged by its ends in housings provided for this purpose in the side wall of said core, the cylindrical surface of the second element is located in said core, the spring bearing on it by its central portion.
L'état de la technique fait par ailleurs appel à des mécanismes indicateurs de la réserve de marche comportant un différentiel qui permet la prise de mouvement sur les deux entrées que sont la marche (rotation du barillet) et le remontage (rotation du rochet) sans qu'elles n'interfèrent l'une sur l'autre. Cela permet de visualiser le remontage du mouvement sans pour autant agir sur la marche.The state of the art also uses mechanisms indicating the power reserve including a differential that allows the movement of the two inputs that are walking (rotation of the barrel) and reassembly (rotation of the ratchet) without that they do not interfere with each other. This allows to visualize the reassembly of the movement without acting on the step.
Il est aussi connu de l'état de la technique différents mécanismes destinés à stopper l'armage du ressort de barillet avant que celui-ci atteigne sa tension maximum afin de permettre à la montre de fonctionner dans une plage idéale d'armage du ressort. Certaines pièces d'horlogerie disposent de mécanismes permettant le blocage de la masse oscillante lorsque le ressort de barillet est proche de la surtension. Toutefois, les contraintes sur le mécanisme et la platine causées par l'arrêt et le maintien d'une masse à moment d'inertie élevé ne se prêtent pas à tous les types de mouvement. Une alternative bien connue consiste à utiliser un dispositif de débrayage. Certains de ces dispositifs utilisent une bride glissante insérée entre la spire extérieure et le tambour du barillet et fixée à l'extrémité du ressort par un rivet.It is also known from the state of the art various mechanisms for stopping the winding of the mainspring before it reaches its maximum tension to allow the watch to operate in an ideal range of winding of the spring. Some timepieces have mechanisms for locking the oscillating mass when the mainspring is close to the overvoltage. However, the constraints on the mechanism and platinum caused by stopping and maintaining a mass with high moment of inertia do not lend themselves to all types of movement. A well-known alternative is to use a disengaging device. Some of these devices use a sliding flange inserted between the outer coil and the barrel drum and attached to the end of the spring by a rivet.
L'inconvénient de ce système résulte du fait que la bride d'une part, réduit le volume du barillet, et d'autre part induit une usure prématurée du tambour de barillet et une fatigue accrue du ressort qui se trouve constamment sollicité par le remontage automatique. La réserve de marche s'en trouve réduite.The disadvantage of this system results from the fact that the flange on the one hand, reduces the volume of the barrel, and on the other hand induces premature wear of the barrel drum and increased fatigue of the spring which is constantly solicited by reassembly automatic. The power reserve is reduced.
Ceci étant précisé, l'invention a pour but de proposer un dispositif de remontage d'une montre automatique comportant un système de débrayage qui n'exerce que peu de contraintes sur le mécanisme et qui par ailleurs ne réduit pas les performances du barillet.This being said, the object of the invention is to propose a device for winding an automatic watch comprising a disengaging system which exerts only few constraints on the mechanism and which moreover does not reduce the performance of the barrel.
L'invention a aussi pour but de proposer un dispositif de remontage adapté pour être couplé d'une part à un mécanisme d'automatique original et d'autre part, à un mécanisme indicateur de la réserve de marche.The invention also aims to propose a winding device adapted to be coupled on the one hand to an original automatic mechanism and on the other hand, to a mechanism indicating the power reserve.
Conformément à l'invention, ce but est atteint grâce à un dispositif de remontage d'un barillet d'un mouvement horloger automatique selon la revendication 1. Ce dispositif comporte une roue d'armage, un système d'armage comprenant au moins un bras d'armage, agencé pour actionner en rotation la roue d'armage, et un module de débrayage instantané susceptible de débrayer la roue d'armage lorsque le ressort de barillet ne travaille plus dans une plage de tension donnée. Le module de débrayage comporte part, un renvoi, une came et un organe de commande dit commande d'instantané montés coaxialement sur un axe, le renvoi étant agencé pour être entraîné en rotation autour de l'axe par un train de renvois en prise avec le barillet et avec le rochet du barillet, et d'autre part, un organe de débrayage collaborant avec la came et susceptible de débrayer le bras d'armage de la roue d'armage lorsque l'organe de commande est entraîné en rotation à l'unisson avec la came par l'action d'un sautoir.According to the invention, this object is achieved by means of a device for winding a barrel of an automatic watch movement according to

Selon la forme d'exécution préférentielle de la présente invention, le dispositif de remontage comprend, selon la

Dans cette forme d'exécution préférentielle, les rapports entre les divers renvois illustrés par la
Dans une variante d'exécution, d'autres rapports démultiplicateurs peuvent être utilisés afin que le module de débrayage 11 effectue non pas une rotation complète dans la période correspondant à la réserve de marche de la montre, mais parcourt un secteur angulaire d'un angle quelconque pendant cette période.In an alternative embodiment, other gear ratios can be used so that the clutch module 11 does not perform a complete rotation in the period corresponding to the power reserve of the watch, but runs through an angular sector of an angle during this period.
Comme on peut le voir à la
Au cours de la marche du mouvement ou pendant le remontage de celui-ci, le renvoi 17 entraine simultanément la commande d'instantané 19 et la came 18 par l'intermédiaire de la goupille 22.During the course of the movement or during reassembly thereof, the
Le caractère instantané de ce module est réalisé grâce à un sautoir d'instantané 25 agencé pour collaborer avec l'extrémité de la commande d'instantané 19. Cette extrémité comporte deux flancs 19a, 19b (
Afin de mieux comprendre le fonctionnement de ce module de débrayage 11, celui-ci est représenté par les

Selon la
La commande 19 est ensuite entraînée en rotation à l'unisson avec la came 18, par l'action du sautoir 25, d'un angle correspondant au jeu existant entre la circonférence de la goupille 22 et l'un des bords latéraux de l'oblong 23. La pente de la came 18 repousse ainsi le palpeur 15" du levier de débrayage 14 afin que celui-ci pivote autour de son axe de rotation 14' repoussant ainsi le bras 2' "crocheteur" du levier d'armage 1 sous l'action de la goupille 24 du levier 14 sur la portion 4" dudit bras 2' (
Dès le débrayage du dispositif de remontage, l'autre des flancs 19a, 19b de la commande d'instantané 19 se retrouve contre l'autre pente de la tête du sautoir 25. Lorsque le ressort de barillet se détend et ne se trouve plus dans une zone de fonctionnement proche sa tension maximum, la commande d'instantané 19 soulève à nouveau la tête du sautoir 25 (
Un mécanisme indicateur de la réserve de marche (IRM) est avantageusement couplé au dispositif de remontage. Lors du remontage de la montre, le barillet tournant toujours à la même vitesse, le mécanisme IRM doit permettre de visualiser le remontage de ladite montre sans pour autant agir sur la marche afin de pouvoir lire l'indication de la réserve de marche en temps réel par l'intermédiaire d'une aiguille, d'un disque, d'un guichet de tout autre moyen existant (non représenté).An indicator mechanism of the power reserve (IRM) is advantageously coupled to the winding device. When reassembling the watch, the barrel still rotating at the same speed, the IRM mechanism must allow to visualize the reassembly of said watch without acting on the step in order to read the indication of the power reserve in real time via a needle, a disk, a window of any other existing means (not shown).
