Device for correcting a timepiece display mechanism

摘要

The invention relates to a device for correcting a time indication given by a display mechanism for a timepiece of the type comprising a first display member, comprising:
a winding stem arranged to occupy at least one time indication correction position A,a pinion coupled in rotation to the winding stem,a correction motion transfer connected kinematically to the pinion when the stem is occupying the correction position A, anda correction wheel assembly engaging with the display member and operated by the correction motion transfer. According to the invention, the correction motion transfer is formed by a ring having an internal circumference and an external circumference, at least one of which is provided with teeth meshing at least indirectly with said correction wheel assembly.

主权项

1. A timepiece comprising:
(a) a first rotatable ring-shaped display member and a bottom plate; (b) a display mechanism for the timepiece; and (c) a device for correcting a time indication that is supplied by the display mechanism, wherein the device for correcting a time indication comprises
(1) a winding stem arranged to occupy at least one time indication correcting position;(2) a pinion mounted on the winding stem and secured thereto in rotation;(3) an intermediate corrector wheel kinematically connected to the pinion when the stem is occupying the at least one time indication correcting position; and(4) a corrector wheel set that cooperates with the first rotatable ring-shaped display member and is actuated by the intermediate corrector wheel, wherein the intermediate corrector wheel is a ring with an inner circumference and an outer circumference, wherein at least one of the inner circumference and the outer circumference has teeth that mesh, at least indirectly, with the corrector wheel set, wherein the ring has space at the centre thereof adapted for housing parts of the timepiece, and wherein a diameter of the intermediate corrector wheel is close to a diameter of the first rotatable ring-shaped display member, thereby freeing space for housing parts of the timepiece and freeing space for the corrector wheel set away from the immediate vicinity of the winding stem.
