L'invention concerne encore un mouvement d'horlogerie comportant au moins un tel mécanisme de correction rapide.The invention also relates to a watch movement comprising at least one such rapid correction mechanism.

L'invention concerne encore une pièce d'horlogerie ou montre comportant au moins un tel mouvement et/ou au moins un tel mécanisme de correction rapide.The invention also relates to a timepiece or watch comprising at least one such movement and / or at least one such rapid correction mechanism.

L'invention concerne le domaine des mécanismes d'horlogerie, et plus particulièrement des mécanismes de correction rapide.The invention relates to the field of watch mechanisms, and more particularly to rapid correction mechanisms.

Arrière-plan de l'inventionBackground of the invention

Cette invention concerne les montres qui nécessitent un mécanisme de correction rapide (jour, mois, ou autre) de certaines fonctions, en particulier des fonctions d'affichage telles qu'un quantième (annuel, perpétuel, jour/date, ou autre), ou des indicateurs de phase de lune, de marée, d'affichage AM/PM, ou autres. Un exemple particulier d'un mécanisme de quantième annuel est décrit par le brevet EP1666991B1 au nom de ETA SA.This invention relates to watches that require a fast correction mechanism (day, month, or other) of certain functions, in particular display functions such as a calendar (annual, perpetual, day / date, or other), or moon phase, tide, AM / PM, or other indicators. A particular example of an annual calendar mechanism is described by the patent EP1666991B1 in the name of ETA SA.

Pour effectuer une correction du mois, l'utilisateur doit généralement effectuer une correction par le quantième. Dans les cas les plus défavorables, une telle manipulation peut s'avérer longue et fastidieuse. Il se peut que l'on doive effectuer une correction d'une année entière. De même si l'utilisateur se trompe lors de la correction, la manipulation doit être réitérée. L'exécution du mécanisme de correction par le quantième pourrait conduire à un emploi excessif et éventuellement créer des dysfonctionnements.To make a correction of the month, the user must generally make a correction by the date. In the most unfavorable cases, such manipulation can be long and tedious. It may be necessary to make a one-year correction. Similarly if the user is mistaken during the correction, the manipulation must be repeated. The execution of the correction mechanism by the date could lead to excessive use and possibly create malfunctions.

Les mécanismes de correction comportent souvent des bascules, qui sont des composants essentiels dans les mécanismes d'horlogerie, permettant de commuter un mécanisme entre plusieurs modes différents, en général entre deux positions distinctes. Une bascule d'horlogerie est souvent accompagnée d'un ressort de rappel pour assurer une transmission de mouvement correcte, ou un appui maintenu, selon le cas.The correction mechanisms often include flip-flops, which are essential components in clockwork mechanisms, making it possible to switch a mechanism between several different modes, generally between two distinct positions. A clock rocker is often accompanied by a return spring to ensure a proper movement transmission, or a support maintained, as appropriate.

Le document FR 2 289 947 A1 au nom de SCHILD décrit un mécanisme de remontoir et de mise à l'heure, avec une tige de commande rotative mobile en translation entre au moins deux positions axiales, une tirette pivotant lors de la translation de la tige, un renvoi de mise à l'heure agencé pour entraîner une roue de minuterie lorsque ladite tige est dans ladite position de mise à l'heure, et une roue de couronne montée baladeuse pour un engagement ou désengagement avec une roue à rochet selon le sens de rotation de la tige lorsque celle-ci est en position de remontage. Ce mécanisme comporte un pignon de transmission, solidaire en rotation de la tige, mais maintenu dans une position axiale fixe et en prise permanente avec la roue de couronne et le renvoi de mise à l'heure, et un dispositif de verrouillage commandé par la tirette, et qui maintient la roue de couronne dégagée de la roue à rochet quand la tige est en position de mise à l'heure, et un élément de liaison commandé par la tige pour découpler le renvoi de mise à l'heure de la roue de minuterie lorsque la tige est en position de remontage.The document FR 2 289 947 A1 in the name of SCHILD describes a mechanism for winding and setting time, with a rotating control rod movable in translation between at least two axial positions, a pivoting zipper during the translation of the rod, a setting back time arranged to drive a timer wheel when said rod is in said setting position, and a crown wheel mounted for a commitment or disengagement with a ratchet wheel in the direction of rotation of the rod when the one it is in the position of reassembly. This mechanism comprises a transmission pinion, integral in rotation with the rod, but maintained in a fixed axial position and in permanent engagement with the crown wheel and the time-setting return, and a pull-operated locking device, which holds the ratchet wheel free from the ratchet wheel when the rod is in the time-setting position, and a controlled link member by the rod to decouple the time setting of the timer wheel when the rod is in the winding position.

Il comporte une tige de commande mobile axialement, une tirette, un pignon-coulant, une bascule de pignon-coulant, et en renvoi de mise à l'heure. Le mécanisme comporte une bascule de correction unique, qui pivote à frottement gras sur un arbre solidaire du renvoi de mise à l'heure, lequel arbre est engagé dans une lumière d'une platine, et sa position dans cette lumière est déterminée par un bras de la bascule de pignon-coulant, qui coopère avec lui pour le déplacer dans cette lumière à l'encontre d'un ressort. Un mobile correcteur est monté pivotant sur la bascule de correction, de manière à être en prise de permanence avec le renvoi de mise à l'heure, et à engrener alternativement avec l'un ou l'autre des deux organes de calendrier.The document CH 589 880 B4 on behalf of SWITZERLAND WATCHING (SSIH) describes a control mechanism for a watch with two calendar organs indicating the day and date.

Une application particulière de l'invention concerne, tel que visible sur les figures 3 à 5, son intégration dans un mécanisme de quantième annuel tel que décrit par le brevet EP1666991B1 du même déposant.A particular application of the invention concerns, as visible on the Figures 3 to 5 , its integration into an annual calendar mechanism as described by the patent EP1666991B1 the same depositor.

Ce mécanisme comprend une roue entraîneuse indicateur quantième 1 équipée de deux doigts dont un premier doigt entraîne une fois par jour un anneau 'indicateur quantième 3 de 31 dents, et dont un deuxième doigt entraîne à la fin des mois de moins de 31 jours une came 2 disposée coaxialement à une étoile des mois 4 composée de 24 dents.This mechanism comprises a date-indicator driving wheel equipped with two fingers, a first finger of which once a day carries a date indicator ring 3 of 31 teeth, and a second finger of which at the end of months of less than 31 days produces a cam. 2 disposed coaxially to a star of the months 4 composed of 24 teeth.

A la fin des mois, l'anneau indicateur quantième 3 entraîne, au moyen d'un ergot, la roue entraîneuse 6 composée de deux étages et reliant l'étoile des mois 4 de 24 dents et un disque des mois 5 de 12 dents. A la fin des mois de moins de 31 jours, le doigt de la roue entraîneuse indicateur quantième 1 entraîne la came 2, et l'étoile des mois 4 entraîne de ce fait, d'une part la roue entraîneuse 6 et l'indicateur quantième 3 par son ergot, et d'autre part le disque des mois 5.At the end of the month, the date indicator ring 3 drives, by means of a pin, the driving wheel 6 composed of two stages and connecting the star of the 4 months of 24 teeth and a disc of the months 5 of 12 teeth. At the end of the months of less than 31 days, the finger of the driving wheel indicator date 1 drives the cam 2, and the star of the months 4 causes, on the one hand, the driving wheel 6 and the date indicator 3 by his ergot, and on the other hand the disc of the months 5.

Lorsque l'utilisateur actionne une tige de remontoir 17 pour effectuer une correction rapide du mois, le pignon coulant 16 classiquement associé à cette tige 17 entraîne un renvoi 10, qui entraîne un renvoi intermédiaire 11 reliant un baladeur à friction constitué par une bascule 100 selon l'invention, pouvant occuper plusieurs positions, et permettant d'effectuer une correction rapide.When the user actuates a winding stem 17 to effect a quick correction of the month, the sliding pinion 16 conventionally associated with this rod 17 causes a return 10, which causes an intermediate return 11 connecting a sliding player constituted by a rocker 100 according to the invention, can occupy several positions, and to perform a quick correction.

La bascule 100 comprend, tel que décrit plus haut: une planche roue correcteur 15, un moyeu 13, un doigt correcteur quantième 14, un renvoi correcteur 12, tous montés sur une plaque pivotante 8 comportant des lames flexibles 85 autour de rainures 83 et 84, ces lames flexibles 85 étant agencées pour pincer le moyeu de certains mobiles en établissant une liaison à friction. Cet agencement n'interdit pas le simple guidage en pivotement d'un moyeu, sans serrage, dans l'un des logements que comporte cette plaque pivotante définis par l'une des surfaces intérieures 81 ou 82.The flip-flop 100 comprises, as described above: a corrector wheel plate 15, a hub 13, a date correction finger 14, a corrector wheel 12, all mounted on a pivoting plate 8 having flexible blades 85 around grooves 83 and 84, these flexible blades 85 being arranged to clamp the hub of some mobile by establishing a friction connection. This arrangement does not prohibit the simple guidance in pivoting of a hub, without tightening, in one of the housings that includes this pivoting plate defined by one of the inner surfaces 81 or 82.

La planche roue correcteur 15 est montée sur un moyeu 13 qui comprend solidairement un doigt correcteur quantième 14 et un renvoi correcteur 12. Le ressort correcteur 8 pivote sur l'axe du renvoi intermédiaire 11 et maintient par pincement le moyeu 13 entraînant la bascule 100 dans l'une des positions selon le sens de rotation de la planche roue correcteur 15, afin de permettre une correction de l'indicateur quantième 3, ou du disque des mois 5 par la roue entraîneuse 6. Afin d'éviter une cassure, le moyeu 13 du correcteur quantième est maintenu par friction sur la planche roue correcteur 15, limitant ainsi le couple transmis.The correction wheel plate 15 is mounted on a hub 13 which comprises a date correction finger 14 and a corrector 12 integrally. The corrector spring 8 pivots on the axis of the intermediate return 11 and pinches the hub 13 driving the rocker 100 into position. one of the positions according to the direction of rotation of the corrective wheel board 15, to allow a correction of the date indicator 3, or the disc of months 5 by the driving wheel 6. In order to avoid a break, the hub 13 of the date corrector is held by friction on the corrector wheel plate 15, thus limiting the transmitted torque.

Naturellement d'autres complications peuvent être commandées de façon similaire à l'aide de la bascule selon l'invention.Naturally other complications can be similarly controlled using the rocker according to the invention.

Naturellement, si l'invention est décrite dans une utilisation particulière où la commande d'entrée est fait par le mobile d'entrée 2 ou par la plaque pivotante 8, pour transmettre un mouvement à l'un des mobiles récepteurs, il est clair qu'un tel mécanisme de correction rapide 200 peut être utilisé en mode réverse avec une sortie vers le mobile 2 ou la plaque pivotante 8.Naturally, if the invention is described in a particular use where the input control is made by the input mobile 2 or by the pivot plate 8, to transmit a movement to one of the mobile receivers, it is clear that such a fast correction mechanism 200 can be used in reverse mode with an output to the mobile 2 or the swivel plate 8.

Les avantages de l'invention sont multiples :

  • la bascule peut fonctionner sans ressort de rappel pour son mouvement de pivotement, même si naturellement un tel ressort peut être rajouté pour privilégier un retour à une position de repos, ou pour favoriser un engrènement par défaut avec un des mobiles récepteurs plutôt qu'un autre ;
  • dans une réalisation comportant des roues dentées, telle qu'illustrée par les figures, lors de l'engrènement d'un côté ou l'autre de la bascule, l'effort tend toujours à pousser les roues l'une contre l'autre, de façon constante, et un bon engrènement est ainsi favorisé, en même temps que tout dégrènement inopiné ou grattage du système est évité ;
  • quand le mobile émetteur d'entrée de la bascule est relié cinématiquement à une tige manoeuvrée par l'utilisateur, par l'intermédiaire par exemple d'un pignon coulant, le basculement entre les deux positions se fait sous l'action de l'effort imprimé par l'utilisateur à la tige, mais sans risque de casser un composant, grâce à la friction ;
  • le système est plus compact qu'un frein à friction ; il autorise la transmission d'un couple important compatible avec toutes les fonctions horlogères ;
  • les usinages de la plaque pivotante de bascule sont peu complexes ; sa conception se prête bien à une réalisation de type silicium, par procédé « MEMS », « LIGA », ou similaire.
The advantages of the invention are manifold:
  • the rocker can operate without return spring for its pivoting movement, although of course such a spring can be added to favor a return to a rest position, or to promote a default meshing with one of the mobile receivers rather than another ;
  • in an embodiment comprising gear wheels, as illustrated by the figures, when meshing with one side or the other of the rocker, the force always tends to push the wheels against each other, in a constant way, and a good meshing is thus favored, at the same time as any sudden unraveling or scraping of the system is avoided;
  • when the mobile transmitter input of the latch is kinematically connected to a rod operated by the user, for example via a sliding pinion, the tilting between the two positions is under the action of the effort printed by the user at the rod, but without the risk of breaking a component, thanks to the friction;
  • the system is more compact than a friction brake; it allows the transmission of a large torque compatible with all the watch functions;
  • machining of the tilting pivot plate is not very complex; its design lends itself well to a realization of silicon type, by "MEMS" method, "LIGA", or similar.

Le système de correction rapide avec baladeur à friction selon l'invention est facile à utiliser pour tout type de correction rapide : jours, mois, ou autres.The rapid correction system with frictional player according to the invention is easy to use for any type of quick correction: days, months, or other.
