Hammer for a timepiece mechanism, timepiece mechanism, in particular striking mechanism, equipped with it, and timepiece comprising them

摘要

The hammer (10) has parts (12, 14) articulated between them, and an elastic unit (162) fixed on one of the parts. The parts are displaced with respect to each other between a stable configuration, in which the parts are maintained under the action of the elastic unit, and a hammer configuration, in which the parts are displaced against the action of the elastic unit. The part (12) is rotated rearward with respect to the part (14) maintained against a fixed stop for returning the hammer to the stable configuration.
