Shock-proof system with simplified assembly for timepiece

摘要

A shock-absorber bearing for a staff of a moving part of a timepiece, the bearing including: a support including a housing configured to receive a pivot module configured to cooperate with the staff; an elastic mechanism configured to exert at least one axial force on the pivot module to retain the pivot module in its housing, the pivot module and the housing having a geometry of revolution defined to have freedom of angular orientation, one relative to the other; and a fixing mechanism for fixing the elastic mechanism.

1. A shock-absorber bearing for a staff of a moving part of a timepiece, the bearing comprising:
a support including a housing configured to receive a pivot module configured to cooperate with the staff, the pivot module including at least one stone; an elastic mechanism configured to exert at least one axial force on a top of the at least one stone towards the staff to retain the pivot module in its housing, the pivot module and the housing having a geometry of revolution defined to have freedom of angular orientation, one relative to the other; a fixing mechanism to fix the elastic mechanism to the support; wherein at least the elastic mechanism has a geometry of revolution defined to have a 360° freedom of angular orientation relative to the pivot module and to the housing, and the fixing mechanism is configured to fix the elastic mechanism to the support whatever an angular orientation of the elastic mechanism relative to the pivot module and to the housing, allowing the bearing to be mounted vertically from top to down by placing elements of the bearing one on the other.
