Abstract (en)
[origin: US2019163134A1] Timepiece wheel set with a unidirectional wheel rotating in only one direction in cooperation with a ratchet wheel, which is movable inside a ratchet wheel chamber, comprising a click that rotates integrally with this wheel, which forms a one-piece component comprising at least one spring-arm, at the end of which, on a first side, a beak cooperates directly with the toothing of a ratchet wheel in an operating position in which this spring-arm is free, and on a second side, a first hook can cooperate with a second hook of complementary shape, comprised in this one-piece click, in a rest position in which this spring-arm is in an extended position, the elasticity thereof allowing this first hook to be hooked or unhooked with respect to this second hook by the action of an operator, by maximum elongation of this spring-arm and/or by the tilting of this end.
