Optimized escapement with safety measures

摘要

The escapement mechanism (1) includes a stop member (3), the stop member (3) comprises a first actuator (31) cooperating with the resonator (2) and a second actuator And a second actuator (32) cooperating with the set (4), wherein the first actuator (31) comprises a magnetized or charged pole piece (310) and the resonator (2) is magnetized or Wherein the pole piece and / or the pole piece comprises a charged track and the pole piece and / or the track have a magnetic field or an electrostatic field in the air gap between the pole piece and the track, Wherein the magnetic field or the electrostatic field has a strength which guarantees the relative drive of the stop member and the resonator when the torque is lower than the reference torque and the stop member and / / Or the resonator (2) comprises stop means (211, 311) for limiting the relative movement between the actuator (31) and the resonator (2) if the torque is greater than the reference torque.BACKGROUND OF THE INVENTION
