Mechanical horological movement provided with an escapement comprising an anchor

A horological movement comprising:

• a mechanical resonator;
• and
• an escapement which is connected to said mechanical resonator, the escapement comprising an escapement wheel, which has a plurality of projecting parts, and an anchor which is separated from the mechanical resonator and which has a single geometric axis of rotation;
• the mechanical resonator being coupled to the anchor such that when said mechanical resonator is maintained in oscillation, the anchor is subject to an alternative rocking movement between first and second rest positions wherein the anchor rests alternatively during successive time intervals,
• wherein the anchor comprises:
• a single pivoting axis centered on said single geometric axis of rotation,
• a rigid connecting portion to which the pivoting axis is fixed,
• two arms connected, at firsts ends thereof, to the connecting portion and having respectively, at a second end thereof, a mechanical pallet which is each able to come into contact with any projecting part of the plurality of parts projecting from the escapement wheel and which are arranged to cooperate with the projecting parts at least in a start-up phase or during normal functioning of the horological movement,
• a fork having two horns and arranged to cooperate with the mechanical resonator via a pin integral with an axis of said mechanical resonator, and
• a stick with a first end connected to said connecting portion and a second end connected to the fork, said stick being free between the first end thereof and the second end thereof;
• wherein, during rocking of the anchor from the first rest to the second rest position while the escapement wheel is positioned in any angular position of a plurality of ranges of angular positions corresponding respectively to said plurality of projecting parts, one mechanical pallets abuts against one of the projecting parts before the anchor can reach an angular position of disengagement of the pin from a side of the second rest position,
• wherein the anchor is arranged, during said rocking of the anchor, to be able to bend in a general plane of the anchor parallel to the fork, by being subjected to elastic deformation from the action of a force exerted by the pin engaged in the fork on one of the two horns of the fork while said one of the mechanical pallets abuts against said one of the projecting parts and the mechanical resonator is braked by the anchor;
• said anchor having an elastic capacity, between each of the mechanical pallets and the fork, enabling the anchor to absorb elastically, during said elastic deformation, a maximum mechanical energy which the mechanical resonator can have during the normal functioning of the horological movement;
• and
• wherein the escapement comprises a magnetic system magnetically coupling the escapement wheel and the anchor, the magnetic system including a magnet supported at each of the mechanical pallets, and a periodic magnetized structure arranged on a disk, the periodic magnetized structure being provided on the escapement wheel.
