LOCKING MECHANISM FOR TIMEPIECE DRIVE MODULE

摘要

PURPOSE: A locking mechanism for a timepiece drive module is provided to improve function and reduce total cost as a magnet is not required for putting a positioning torque into an idle state of a rest state. CONSTITUTION: A module comprises an actuator press-fitted with an active click(5) cooperating with a toothed wheel(7). The apparatus comprises a second finger and a first finger cooperating with the toothed wheel. As the first finger meshes with one of the toothed wheels, the first finger locks with the rotation of the toothed wheel. The second finger is arranged between a first stop member(10) and a second stop member(11). As the second finger goes in gear with one of the saw blades of the toothed wheel, a space between the stop members restricts each angular travel of the toothed wheel.
