Claim 0:
1. A direct impulse free escapement mechanism for a timepiece, comprising:
an escapement wheel, extending in a plane P1 and rotatable about a first axis of rotation perpendicular to this plane P1 and provided with a series of peripheral teeth, said teeth defining by their ends during rotation of the escapement wheel a circular trajectory C,
a locking device comprising at least one locking pallet arranged to cooperate in abutment with one of said teeth of the escapement wheel in at least one locking position of said locking device,
at least one control pallet capable of being attached to a regulating organ pivoting about a second axis of rotation in order to cooperate with at least one complementary unlocking organ of the locking device in order to release the locking device from the escapement wheel in an unlocking position at each alternation of said regulating organ,
impulse pallets capable of being attached to said regulating organ to cooperate each on an impulse plane of one of the impulse pallets with the one of said teeth of the escapement wheel to transmit a direct impulse to said regulating organ;, wherein the locking device is arranged to undergo a draw by the escapement wheel in each locking position and that the teeth of the escapement wheel and the impulse pallets are configured and arranged such that the impulses occur outside the plane P1 of the escapement wheel.
