Clockwork device for use in movement of e.g. wrist watch, has stop pin for blocking jumping wheel and releasing wheel at determined instant to allow pivoting element to be returned to initial position by return spring

摘要

#CMT# #/CMT# The device has a stop pin (60) blocking a jumping wheel i.e. hour wheel (46), and a pivoting element i.e. frame (47), armed by rotating a drive wheel i.e. hour wheel (45), and engaging between the drive wheel and one of satellite wheels (49, 50). The stop pin releases the jumping wheel at a determined instant while arming the pivoting element to allow the pivoting element to be returned to initial position by a return spring (48) to allow rotation jump of the jumping wheel by engaging between the wheel and the jumping wheel. #CMT#USE : #/CMT# Clockwork device for use in a movement of a time-piece e.g. wrist watch. #CMT#ADVANTAGE : #/CMT# The device utilizes reduced number of second wheels so as to realize a compact movement plane timepiece. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of a display device. 45, 46 : Hour wheels 47 : Frame 48 : Return spring 49, 50 : Satellite wheels 60 : Stop pin.
