Contactless cylinder escapement mechanism for timepieces
First Claim
1. A timepiece escapement mechanism, comprising:
- an escape wheel subjected to a rotational torque, having a lower or equal moment to a nominal moment, about a first pivot axis; and
a resonator integral with a regulating wheel set mounted to pivot about a second real or virtual pivot axis;
the escape wheel including a plurality of actuators regularly spaced on a periphery thereof and each arranged to cooperate directly with at least a first track of the regulating wheel set;
wherein each actuator includes first magnetic or electrostatic stopping means forming a barrier and arranged to cooperate with the first track which is magnetically, or respectively electrically charged, or ferromagnetic, or respectively electrostatically conductive, to exert on the first track a torque having a moment greater than the nominal moment; and
wherein each actuator further includes second stopping means arranged to constitute an end-of-travel stop, arranged to constitute an autonomous escapement mechanism with at least a first complementary stop surface included in the regulating wheel set.

Abstract
An escapement mechanism including an escape wheel subjected to a rotational torque and a resonator integral with a pivotally mounted regulating wheel set. The escape wheel includes plural actuators regularly spaced on a periphery thereof, each arranged to cooperate directly with at least a first track of the regulating wheel set. Each actuator includes a first magnetically, or respectively electrically charged, or ferromagnetic or respectively electrostatically conductive surface, to cooperate with the first track which is magnetically, or respectively electrically charged, or ferromagnetic or respectively electrostatically conductive, to repel or attract each first surface of the actuator, and each actuator includes a mechanical stop member to cooperate, in an end-of-travel stop arrangement, with at least a first complementary stop surface included in the regulating wheel set to constitute therewith an autonomous escapement mechanism.
