  • Horology pawl system
    Patent number: 10890877
    Abstract: A pawl system (1) for a wheel (2) of a drivetrain for winding a horology barrel (3), including (i) a pawl (10) having at least one tooth (1a) intended to collaborate with a toothset (2a) of the wheel (2); and (ii) an element (6) for activating and deactivating the pawl, which is arranged so that, when it is in a first configuration, the at least one tooth (1a) of the pawl collaborates with the toothset (2a) directly or indirectly, notably under the effect of a return force returning the at least one tooth (1a) of the pawl against the toothset (2a), and, when the activation and deactivation element is in a second configuration, the at least one tooth (1a) of the pawl does not collaborate with the toothset (2a) or a return force returning the at least one tooth (1a) of the pawl against the toothset (2a) is reduced.
