the beak 13 of that other tooth 12 leaves the impulse pallet stone 4 at its impulse beak 20 fig1 and 18 also illustrate the cooperation between the pin 7 and the fork 5 the thrust from the escapement pallet 2 on the sprung balance is then interrupted and the plate 6 freely continues its movement preceding the next escapement function this then results in a drop phase in which the escape wheel 1 which is momentarily free finishes its travel with a bearing of another tooth 12 on the other rest pallet stone 3 u2032 there is then another rest phase fig2 illustrates the escapement mechanism according to the invention during a rest phase and fig2 and 22 illustrate enlargements a and c of the escapement system during that second rest phase fig2 illustrates another example embodiment of the escapement system according to the invention in the second impulse phase in this example embodiment the escape wheel 1 includes eleven teeth 12 the escapement mechanism according to the invention is advantageously integrated into a timepiece of the bracelet watch or other type furthermore the body 2 a has straight sectors 2 c favoring the guiding and sliding of the escapement pallet 2 on bearing points secured to the frame of a timepiece box or platen the escapement mechanism therefore comprises means for guiding the sliding of the body 2 a arranged to cooperate with bearing elements secured to a frame of a timepiece the timepiece for example comprises bearing element secured to the frame arranged to cooperate with means for guiding the sliding of the body 2 a during its alternating translational movements according to another example embodiment of the escapement mechanism according to the invention illustrated in fig2 the.
