ESCAPEMENT MECHANISM FOR TIMEPIECE

The present invention relates to a direct escapement mechanism (1) having an escape wheel (2) provided with a series of peripheral teeth (3), and an anchor (4), having an entry-pallet (10) and an exit-pallet (11) each having a locking plane (10p, 11p) and also having a fork (43). It also comprises a pin (6) which can be rigidly connected to a regulating organ (5) to cooperate at each alternation of said regulating organ (5) with the fork (43) of the anchor in order to unlock at least partially said anchor from the escape wheel (2) as well as at least one impulse pallet (9) which can be rigidly connected to said regulating organ (5) to cooperate with a tooth (3) of the escape wheel to transmit a direct impulse to said regulating organ (5). Typically, at least the teeth (3) of the escape wheel or one of the entry-pallets or exit-pallets (11) comprises in the extension of said locking plane (10p, 11p) a inclined plane (3i, 10i, 11i) arranged to provide an indirect impulse to said regulating organ (5) during a movement of said pallet in the path C of the escape wheel (2) by rotating the anchor (4) on its axis (X3).The invention also relates to a timepiece incorporating such an escapement mechanism.
