#CMT# #/CMT# The mechanism has a twenty-four hours wheel (1) i.e. toothed wheel, with an opening. A spring (2) has a central part (8) and a resilient arm (9) whose free end is provided with a finger cooperating with a date indicator (12) for changing a date (14). The twenty-four hours wheel and the spring are integrated to a shaft (19). The finger has a hole provided against a stationary abutment forming piece (3). The opening of the twenty-four hours wheel receives a portion of the finger. A part of a border of the opening permits to release the finger from the abutment forming piece. #CMT# : #/CMT# An independent claim is also included for a calendar implemented timepiece comprising teeth arranged close to a finger when the finger is stopped against an abutment forming piece. #CMT#USE : #/CMT# Mechanism for driving a date indicator in a calendar implemented timepiece (claimed). #CMT#ADVANTAGE : #/CMT# The driving mechanism has reduced number of parts, so that the mechanism does not require high consumption of energy during its operation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic diagram of a date indicator driving mechanism during a moment where winding of a spring is started. 1 : Twenty-four hour wheel 2 : Spring 3 : Stationary abutment forming piece 8 : Central part 9 : Resilient arm 12 : Date indicator 14 : Date 19 : Shaft. |
