Title (EN) MECHANICAL TIMEPIECE WITH TIMED ANNULAR BALANCE ROTATING ANGLE CONTROL MECHANISM
(FR) PIECE D'HORLOGERIE MECANIQUE DOTEE D'UN MECANISME DE COMMANDE DE L'ANGLE DE ROTATION DU BALANCIER ANNULAIRE REGLE
Abstract:
(EN) A mechanical timepiece with timed annular balance rotating angle control mechanism, comprising a switch mechanism (168, 168a, 168b) outputting ON or OFF signals according to the rotating angle of a timed annular balance (140) and a circuit board (612) having a pattern providing conduction between a plurality of coils (180, 180a, 180b, 180c), wherein the coils (180, 180a, 180b, 180c) are structured so that they suppress the rotation of the timed annular balance by applying a magnetic force to a timed annular balance magnet (140e) when the switch mechanism (168, 168a, 168b) outputs ON signals, and do not apply the magnetic force to the timed annular balance magnet (140e) when the switch mechanism outputs OFF signals.
(FR) L'invention se rapporte à une pièce d'horlogerie mécanique dotée d'un mécanisme de commande de l'angle de rotation du balancier annulaire réglé. Cette pièce d'horlogerie comporte un mécanisme de commutation (168, 168a, 168b) délivrant des signaux ARRET et MARCHE en fonction de l'angle de rotation d'un balancier annulaire réglé (140) et une carte à circuits (612) ayant un motif assurant la conduction entre une pluralité de bobines (180, 180a, 180b, 180c). Ces bobines (180, 180a, 180b, 180c) sont conçues pour supprimer la rotation du balancier annulaire réglé par application d'une force magnétique à un aimant (140e) dudit balancier annulaire réglé lorsque le mécanisme de commutation (168, 168a, 168b) délivre des signaux MARCHE, lesdites bobines n'appliquant pas de force magnétique à l'aimant du balancier magnétique annulaire réglé (140e) lorsque le mécanisme de commutation délivre des signaux ARRET.
