  • the rest plan of the stopping pallet closest to the escape wheel is in effect before the tooth, and prevents him from continuing on his way.
  • the patent EP 1 708 046 on behalf of WATCHES BREGUET SA discloses a safety finger fixed on the balance plate, and arranged to cooperate with the teeth of the escape wheel and block if the pulse pallet was to be released by accident of the teeth of wheel. This arrangement prevents any panic of the escape wheel in the event of shock resulting in the reversal of the direction of rotation of the trays at the precise moment of the impulse of the wheel. The encounter of a tooth of the wheel with this safety finger blocks the wheel, brings back the trays in the correct direction of rotation.
  • a first mobile is subjected to a periodic torque, obtained for example by a rotor mounted in a stator.
  • This first mobile comprises, firstly in a base plane a first wheel having teething gaps on its periphery, and secondly on a second plane a first blocker having a plurality of fingers and adapted to block a release lever that includes a balance plate, in a first pivoting direction of this last.

  • the locking pieces, or of shape, or the teeth cooperate with each other, so that the device has, for each revolution of rotation of the first axis, four stable locking positions, between which it has so many unlocking positions.
  • the combination of two locking means and two means of unlocking the mechanical torque, and the particular sequence imposing an unlocking operation between two blocking operations realize the prevention of any runaway or gallop in case of impact on the mechanism.
  • Such a mechanism is complex, relatively expensive, and unfolds in several planes, which makes its thickness significant.
  • a large platform of the balance typically carries a pulse pallet, preceded by a first recess, and followed by a second recess, to allow the release of the pallet rest when the release pallet rotates the trigger rocker.
  • the choice of a particular geometry both in terms of the positioning of the pallet of rest and the pallet of impulse in quasi-symmetry of the line of the centers of the escape wheel and the pendulum during the phase of rest, which 'at the fork formed by the finger and the free end of the leaf spring, limit the disruptive effect related to the inertia of the trigger on the pendulum oscillations.
  • the amplitude of the pivoting movements of the trigger in case of shock, is limited by the interaction of the pallet rest and large plateau.
  • this mechanism comprises an anti-gallop rocker, in the vicinity of the small plate, pivotally mounted on the movement between two stable end positions held by a jumper on stops with which can cooperate a first end, and a fork-shaped second end interacts with the release pallet: at each passage through the fork, the release pallet exerts pressure to tilt the anti-gallop rocker from one to the other of its stable positions.
  • the fork is thus two stops for the small plateau in case of galloping, and prevents the pendulum to do more than one turn in pivoting.
  • the document EP 1 860 511 in the name of Christophe Claret SA describes a moving bridge movement, providing protection against side impacts of a detent escapement.
  • This movable bridge carries the pivot axis of the sprung balance, the pivot axis of the escape wheel, the pivot axis of the trigger, and a part of the finishing gear. It is rotated elastically on the axis of one of the wheels of the cogwheel finishing, for example the second wheel. Forces, such as a side impact, capable of disengaging the pallet of rest, then drive the movable bridge in its entirety, and the relative positions of the trigger and the escape wheel are maintained. Thus, a constant step of the exhaust is ensured.
  • This movable bridge can, again, be damped by a damping system that allows to dissipate some of the energy due to impact.
  • the patent application CH 700 091 in the name of Christophe Claret SA describes a detent escapement, with a trigger rocker pivotally mounted on a spiral spring and cooperating at the other end with a first recessed spring blade in the vicinity of the pivot.

This cam is arranged to cooperate the cam spring-blade, or in a first state with the end of the load-bearing latch of the leaf spring, or in a second state with the pallets of release of the balance.
  • the first release pallet is arranged to cooperate with the first leaf spring and operate the trigger when the first paddle crosses the first blade in a first direction, and to cooperate only with the first blade and without actuating the trigger when it crosses in the opposite direction.
  • the cam in its first state, cooperates with the trigger to limit the movements thereof.
  • the second clearance pallet is arranged to move the cam into its second state where the trigger is free to perform its release and release the exhaust wheel tooth of the pallet rest.
  • the two clearance pallets are close together, and arranged in such a way that the cam is brought into its second state just before the detent makes its release.
  • the spiral return cam spring stronger than the cam spring blade, tends to return the cam to its first state.
  • the cam in its first state, is positioned to oppose everything inadvertent movement of the trigger that would result in an untimely release of the pallet rest, and the exhaust is less sensitive to the effects of a shock.

Its trigger rocker is arranged in a particular way, pivoting between two stops, it has, turned towards the escape wheel, a finger successively comprising a stop surface serving as a pallet of rest, a safety surface which, depending on the position of pivoting of the rocker, interferes or not with the trajectory of the escape wheel, and a sliding surface which forces the rocker to tilt, during the pivoting of the escape wheel, in order to reduce the sliding surface and therefore the stop surface in the interference zone with the escape wheel to stop the pivoting thereof.
  • the balance plate conventionally comprises a pulse pallet and a release finger.
  • the rocker During the alternation in a first pivoting direction of the balance, the rocker is in a first pivoted position in abutment which leaves the passage to the release finger, while in the other alternation in the other direction of pivoting, the pivoted rocker in another abutment position encounters, at a resilient clearance element that it comprises, the release finger.

  • the rocker remains braced on its stop, and the stop surface of the rocker slides on the tooth of the escape wheel that keeps it in stop.
  • the safety of this mechanism is ensured by the arrangement of the finger of the rocker, with a stop surface and a sliding surface which penetrate alternately in the path of the toothing of the escape wheel.
  • the length of the safety surface between the stop surface and the sliding surface corresponds to the angle traveled by the wheel to communicate the driving energy to the balance, to prevent the premature return of the stop element in the path of the wheel , which constitutes a complementary security. Part of the energy of the cylinder is however consumed in friction during the sliding phase.
