Abstract (en)
[origin: JP2017032564A] PROBLEM TO BE SOLVED: To stop bounces of a magnetic or electrostatic escapement device by adding a non-return device.SOLUTION: In a timepiece escapement mechanism 200, a stopper 2 forms a part of the escapement mechanism 200; an escape wheel 1 includes a succession of tracks carrying magnetic or electrostatic field potential ramps 6; the magnetic or electrostatic field potential ramps 6 are arranged to cooperate with a resonator 100 or individually with the stopper 2; the escapement mechanism 200 comprises a non-return device 5 arranged to oppose the recoil of the escape wheel 1; the stopper 2 cooperates, on the one hand, with a plate forming a part of the resonator mechanism and, on the other hand, with these magnetic or electrostatic field potential ramps 6 by at least one pole shoe 31, 32; the pole shoe 31, 32 forms a part of the stopper 2 and is arranged to move in the field corresponding to the magnetic or electrostatic field potential ramps 6.SELECTED DRAWING: Figure 7
