Title:
SECURE OPTIMIZED ESCAPEMENT
Document Type and Number:
WIPO Patent Application WO/2015/096975
Kind Code:
A3
Abstract:
The invention relates to an escapement mechanism (1) comprising a stop (3) that comprises a first actuator (31), engaging with a resonator (2), and a second actuator (32), engaging with an escapement train (4) subjected to a drive torque lower than a nominal torque. Said first actuator (31) comprises a magnetized or electrically charged pole shoe (310). Said resonator (2) comprises a magnetized or electrically charged track (21), and the pole shoe (310) or/and the track (21) create, within a pole gap (210) between the pole shoe (310) and the track (21), a magnetic or electrostatic field having a strength suitable for relatively driving the stop (3) and the resonator (2) when the torque is lower than the nominal torque. Moreover, the stop (3) or/and the resonator (2) comprise stopping means (211; 311) which restrict the relative range of movement between the actuator (31) and the resonator (2) when the torque is greater than the nominal torque.
