Patent ID: 11480923

Abstract:
An escapement for a timepiece, comprising: —an escapement wheel pivotally mounted around a corresponding axis of rotation and intended to be driven by a drive source, said escapement wheel comprising a plurality of teeth; —a pallet fork pivotably mounted around a corresponding axis of rotation, said pallet fork comprising an entry pallet and an exit pallet, each pallet comprising a rest face arranged to block the escapement wheel, as well as a pulse face arranged to interact with the escapement wheel in order to transmit the pulses received from the latter to a regulating member arranged to perform oscillations, said pallet fork being arranged to free the escapement wheel periodically under the control of the regulating member, characterized in that at least one of the pulse faces is shaped in such a way that, on at least one portion of the pulse face, and considered at each point of contact (C′) between the escapement wheel and the pulse face, the tangent of the pulse face intersects the center-to-center distance between the escapement wheel and the pallet fork according to an angle (αorientation) that observes a particular relation.
