Description

L'invention concerne un mécanisme régulateur d'horlogerie comportant une platine et, montés mobiles au moins en mouvement de pivotement par rapport à ladite platine, un mobile d'échappement qui pivote autour d'un axe d'échappement et est soumis à un couple moteur, et au moins un premier résonateur comportant une première structure rigide reliée à ladite platine par des premiers moyens de rappel élastique, ladite première structure rigide portant au moins un bras inertiel dont un premier bras inertiel agencé pour coopérer avec ledit mobile d'échappement par l'intermédiaire de pistes magnétisées ou/et électrisées que comportent à la fois ledit au moins un premier bras inertiel et ledit mobile d'échappement, pour former un dispositif de synchronisation entre ledit mobile d'échappement et ledit au moins un premier résonateur.The invention relates to a timepiece control mechanism comprising a plate and, movably mounted at least in pivoting movement relative to said plate, an escapement that pivots about an exhaust axis and is subjected to a torque motor, and at least a first resonator comprising a first rigid structure connected to said plate by first resilient return means, said first rigid structure carrying at least one inertial arm including a first inertial arm arranged to cooperate with said exhaust mobile by intermediate magnetized tracks and / or electrified that comprise both said at least a first inertial arm and said exhaust mobile, to form a synchronization device between said exhaust mobile and said at least a first resonator.

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

L'invention concerne encore une pièce d'horlogerie comportant un tel mouvement ou un tel mécanisme régulateur.The invention also relates to a timepiece comprising such a movement or such a regulating mechanism.

L'invention concerne le domaine des mécanismes régulateurs d'horlogerie, notamment des mécanismes d'échappement d'horlogerie, et plus particulièrement, le domaine des échappements sans contact.The invention relates to the field of watchmaking mechanisms, in particular watchmaking exhaust mechanisms, and more particularly to the field of non-contact exhausts.

Arrière-plan de l'inventionBackground of the invention

Le mouvement de la montre mécanique que l'on connaît aujourd'hui est le résultat d'améliorations successives depuis trois siècles. Son échappement à ancre suisse se caractérise par sa robustesse aux chocs. C'est-à-dire que l'état de la montre est peu affecté par un choc ponctuel.The movement of the mechanical watch that we know today is the result of successive improvements for three centuries. Its Swiss lever escapement is characterized by its robustness to shocks. That is to say that the state of the watch is not affected by a punctual shock.

Par contre, le rendement de cet échappement n'est pas très bon (30% environ). D'autre part, l'échappement à ancre suisse ne permet pas d'utiliser des résonateurs dont la fréquence est élevée ou l'amplitude faible.By cons, the performance of this exhaust is not very good (about 30%). On the other hand, the Swiss lever escapement does not allow the use of resonators whose frequency is high or low amplitude.

On cherche donc un moyen de pouvoir utiliser des résonateurs présentant un facteur de qualité élevé, une fréquence élevée, et/ou des amplitudes faibles, tout en augmentant le rendement de l'échappement et sans pour autant abandonner sa robustesse aux chocs.We therefore seek a way to be able to use resonators having a high quality factor, a high frequency, and / or low amplitudes, while increasing the efficiency of the exhaust and without giving up its robustness to shocks.

Parmi les réalisations liées au domaine de l'invention, on connaît:

  • la pendulette à diapason de Clifford ;
  • le mouvement « Resonique® » de « De Bethune® »
  • la montre « Accutron® » de « Bulova®.
Among the achievements related to the field of the invention, we know:
  • Clifford's tuning clock;
  • the "Resonique®" movement of "De Bethune®"
  • the "Accutron®" watch from "Bulova®.

Chacune de ces réalisations présente des avantages particuliers, mais ces mouvements présentent le même inconvénient : ils ne sont pas résistants aux chocs. C'est-à-dire qu'en cas de choc, les aiguilles avancent rapidement.Each of these embodiments has particular advantages, but these movements have the same disadvantage: they are not resistant to shocks. That is to say that in case of shock, the needles advance quickly.

Dans une application particulièrement avantageuse, le mécanisme régulateur 200 constitue un mécanisme de régulation et d'échappement.In a particularly advantageous application, the regulator mechanism 200 constitutes a regulation and exhaust mechanism.

L'invention concerne encore un mouvement d'horlogerie 300 comportant au moins un tel mécanisme régulateur 200.The invention also relates to a clockwork movement 300 comprising at least one such regulating mechanism 200.

L'invention concerne encore une pièce d'horlogerie 400 comportant un tel mouvement 300, ou comportant au moins un tel mécanisme régulateur 200.The invention also concerns a timepiece 400 comprising such a movement 300, or comprising at least one such regulating mechanism 200.

L'avantage de l'invention est de pouvoir concilier le rendement élevé qu'offre un système de synchronisation magnétique (plus de 90%), tout en supprimant son principal défaut, à savoir, le décrochage en cas de couple élevé. La fiabilité est donc améliorée sans altérer les performances de rendement.The advantage of the invention is to reconcile the high efficiency offered by a magnetic synchronization system (more than 90%), while eliminating its main defect, namely, the stall in case of high torque. Reliability is therefore improved without impairing performance performance.

La solution apportée par cette protection en cas de surcharge de couple est peu coûteuse, et facile à combiner avec un mécanisme d'échappement magnétique ou similaire.The solution provided by this protection in case of torque overload is inexpensive, and easy to combine with a magnetic exhaust mechanism or the like.
