Disclosed is an escapement mechanism with a locking anchor for a timepiece including a sprung-balance regulating organ, including an escapement wheel provided with a series of peripheral teeth, and a locking anchor including first and second locking pallets arranged respectively at one end of first and second arms to allow alternately engaging a tooth of the escapement wheel at each rotation step of the escapement wheel and of the anchor about their respective axis of rotation. This mechanism includes an impulse pallet adapted to be fixed to one the regulating organ to transmit an impulse by sliding a tooth of the escapement wheel on an impulse plane of the impulse pallet once at least every two oscillations of the regulating organ while the locking anchor includes a connecting member for permanent kinematic engagement in rotation to the regulating organ. Also disclosed is a timepiece incorporating such an escapement mechanism.

The present invention relates to a mechanical timepiece regulator comprising a constant force escapement and an oscillator; the oscillator comprising a balance connected to an elastic return element of the balance returning the balance into a plane of oscillation such that the balance is able to oscillate; the escapement comprising an escapement wheel and an anchor part, integrated in the balance, an entry pallet lever and an exit pallet lever, each of the pallet levers being mounted on a pallet lever elastic return element configured to be wound by the escapement wheel; the pallet levers being configured to block or release the escapement wheel between two windings of the pallet lever elastic return elements and to cooperate with the anchor part so as to transmit to the balance the energy stored in the pallet lever elastic return elements with each oscillation alternation of the balance.

The micromechanical clockwork part is cut from a plate-like silicon substrate. The cut edges of the part include portions intended to serve as contact surfaces arranged to slide against corresponding contact zones of another micromechanical part in a clockwork piece. The cut edges have a ribbed surface including an alternating set of ribs and furrows, the ribs and the furrows being straight and each contained in a plane parallel to the plate. Moreover, the ribs and furrows which the cut edges have form a stepped pattern on the cut edge, with first intervals in which the spacing separating the ribs from one another is equal to a first distance, and at least one second interval in which the spacing between the ribs is equal to a second distance different from the first distance.
