Title (EN) MECHANICAL TIMEPIECE COMPRISING A MOVEMENT OF WHICH THE OPERATION IS IMPROVED BY A CORRECTION DEVICE
(FR) PIECE D'HORLOGERIE MECANIQUE COMPRENANT UN MOUVEMENT DONT LA MARCHE EST AMELIOREE PAR UN DISPOSITIF DE CORRECTION
Abstract:
(EN) The invention relates to a mechanical timepiece provided with a movement comprising a mechanism indicating at least one time datum, a mechanical resonator (6) forming a slave oscillator that clocks the operation of the indicator mechanism, and a mechanical correction device (52) for preventing a potential time interval error in the operation of the indicator mechanism. The mechanical correction device is formed by a mechanical master oscillator (54) and a mechanical device (56) for braking the mechanical resonator, said braking device being arranged so as to be able to periodically apply mechanical braking pulses to the mechanical resonator at a braking frequency determined by the mechanical master oscillator. Then, the mechanical system, formed by the mechanical resonator and the braking device, is designed so as to allow the braking device to be able to begin the braking pulses preferably at any position of said mechanical resonator. Preferably, the duration of the braking pulses is shorter than a quarter of a nominal period.
(FR) La pièce d'horlogerie mécanique est munie d'un mouvement qui comprend un mécanisme indicateur d'au moins une donnée temporelle, un résonateur mécanique (6) formant un oscillateur esclave qui cadence la marche du mécanisme indicateur, et un dispositif mécanique de correction (52) pour prévenir une dérive temporelle éventuelle dans la marche du mécanisme indicateur. Le dispositif mécanique de correction est formé par un oscillateur mécanique maître (54) et un dispositif mécanique (56) de freinage du résonateur mécanique, ce dispositif de freinage étant agencé pour pouvoir appliquer périodiquement audit résonateur mécanique des impulsions de freinage mécanique à une fréquence de freinage déterminée par l'oscillateur mécanique maître. Ensuite, le système mécanique, formé dudit résonateur mécanique et du dispositif de freinage, est configuré de manière à permettre au dispositif de freinage de pouvoir débuter les impulsions de freinage de préférence à n'importe quelle position dudit résonateur mécanique. De préférence, les impulsions de freinage ont une durée inférieure au quart d'une période de consigne.
