  • the anchor 14 and the escape wheel 16 are arranged so that, in normal operation, one of the teeth 42 of the escape wheel experiences at least one impact on one or the other of the two mechanical paddles after the corresponding magnetic paddle has climbed any one of the increasing ramps of magnetic potential energy following a tilting of the anchor.
  • This shock occurs so as to at least partially dissipate a kinetic energy of the escape wheel acquired following said tilting.
  • the teeth of the escape wheel are designed to be able to absorb the kinetic energy of this escape wheel, with each step of the escape wheel, after an accumulation of magnetic potential energy in the escapement for a subsequent sustain pulse of the mechanical resonator, and thus to limit a terminal oscillation during each step of its step-by-step rotation.

  • the escape wheel 16 can stop in any angular position ⁇ d 'a plurality of ranges of angular positions, corresponding respectively to the plurality of teeth 42, for which one of the two mechanical paddles then abuts against one of these teeth before the anchor can reach the angular position of release of the pin, as shown in Figure 1B .
  • the Figure 1B shows a particularly unfavorable case where an end portion 48 of the mechanical pallet 29 is subjected to an impact on the top of the head 43 of a tooth 42 against which this mechanical pallet abuts.
  • the total force exerted by the anchor on the tooth 42 concerned is substantially radial, in a polar coordinate system associated with the escape wheel, so that the escape wheel is not driven in rotation and suffers a strong shock.
  • the significant shock in question does not relate only to the instant at which the mechanical pallet and the tooth come into contact, but it is about an impulse of radial force which has a certain duration since this shock takes place while the pin of the oscillating resonator is inserted between the two horns 19a and 19b of the fork 18 and a magnetic pulse is supplied to the anchor.
  • the radial force impulse has several components, firstly a component arising from the inertia of the moving anchor 14 which is stopped; secondly, a main component due to the mechanical energy stored in the oscillating mechanical resonator 2 which is stopped in its oscillation while its kinetic energy is almost maximum, via the coupling between the fork 18 and the pin 10; and thirdly a magnetic component resulting from the fact that the shock occurs while a magnetic pulse is supplied to the anchor (represented by an arrow at the Figure 1B ).
  • the anchor 14 is arranged so as to be able, during a tilting during which a shock described above occurs, to bend, in a general plane of the anchor parallel to the fork 18 (this is i.e. parallel, including coincident, to a general plane in which the horns of the fork extend), undergoing an elastic deformation under the action of a force F RO exerted by the ankle 10, engaged in the fork , on one of its two horns 19a, 19b while the mechanical pallet concerned abuts against a tooth and that the mechanical resonator is braked by the anchor.
  • this anchor has an elastic capacity, between each of the two mechanical paddles 18, respectively 29 and the fork 18, allowing it to elastically absorb, during said elastic deformation, a maximum mechanical energy that the mechanical resonator 2 can have during normal operation of the watch movement.
  • this elastic capacity has a certain safety margin, because during the impact there is a certain dissipation of energy in particular at the level of the bearings of the escape wheel, of the mechanical resonator and of the anchor, and also in the various structures concerned, in particular the plate 40. Any breakage or deterioration of the escapement and of the mechanical resonator can thus be avoided.
  • elastic capacity is understood an elastic energy absorption capacity. Thanks to the characteristics of the anchor according to the invention, a sudden shock is avoided and a progressive dissipation of the mechanical energy of the mechanical resonator is allowed.
  • the anchor undergoes an elastic deformation in order to be able to absorb the major part of the mechanical energy of the mechanical resonator, even if this mechanical energy corresponds to a nominal energy in normal operation of the watch movement.
  • the rod 20 which is designed to be able to substantially absorb said major part of the mechanical energy of the mechanical resonator.
  • the rod is designed to be curved, in particular with the general shape of a 'swan neck'. Other shapes are possible, also a substantially rectilinear rod.
  • the curved configuration has an advantage in that it generally makes it possible to increase the length of the rod between the connecting part 25 and the fork 18.
  • the 'gooseneck' shape allows a relatively long length of the rod, while having the fork relatively close to one of the two mechanical paddles.
  • those skilled in the art would connect the shortest fork with the arm 26, in the extension of the mechanical pallet 29.
  • a median geometric line of the anchor 14 between an end surface (terminal inclined plane) of each of the two mechanical pallets 28, 29 and the fork 18, has a total length, on the two sections 20a and 24a, respectively 20a and 26a which are defined by the mechanical pallet considered together with the corresponding arm 24 or 26 and by the rod 20 (see broken lines on Figure 1A ), which is at least twice the length of a straight line 52 between a point of the median geometric line 24a on the end surface closest to the fork and the middle of the bottom of a cavity defined by the two horns of this fork (see Figure 1B ).
  • the elastic deformation capacity can be provided over the entire total length defined above or only over parts of this total length.
  • the rod and the arms have an elastic deformation capacity, which may be different, while in a second variant, it is substantially the rod which has this elastic capacity.
  • it is substantially the arms 24 and 26 which have an elastic capacity.
  • the anchor must therefore have an elastic deformation capacity and a capacity large enough to absorb elastic energy, these associated capacities being a function of several parameters that a person skilled in the art will be able to select and determine in order to obtain the desired values.
  • the shape can play a role, as well as the length of the material path between the mechanical paddles and the fork.
  • Other parameters also play a role, including the material selected and the various cross sections. Note that the minimum cross section of the anchor also plays a role, which should not be too much small by promoting the flexibility of a portion of the anchor to the detriment of elastic energy absorption.
  • magnetic pulses for maintaining the oscillation of the mechanical resonator are generated at the level of the two mechanical vanes 28, 29 which respectively support two magnets 30, 32 forming two magnetic vanes.
  • the anchor 14 is arranged so as to be able, during normal operation of the watch movement and therefore of the escapement, to substantially transmit a torque of magnetic force, generated by each of the magnetic pulses, to its fork in order to maintain a oscillation of the mechanical resonator. It will be noted that this condition can easily be implemented owing to the fact that the quantity of energy in a magnetic pulse is much less than the mechanical energy possessed by the mechanical resonator 2 in normal operation.
  • the resonator having at this instant a nominal and therefore significant mechanical energy, essentially in the form of kinetic energy, it then presses against the horn 19a by exerting a decreasing force F RO while the anchor, here especially the rod 20, flexes in absorbing most of the kinetic energy of the resonator in the form of elastic energy.
  • the angle defined above therefore increases, as shown in Figure 1C where its value a2 is greater than the value a1, for example approximately one value double, the Figure 1C showing a configuration when the mechanical resonator has lost most of its speed (and therefore of its kinetic energy).
  • the mechanical resonator passes through an angular stop position and a premature reversal of the direction of its movement, as shown in Figure 1D where the resonator rotates counterclockwise whereas it previously rotated clockwise.
  • the resonator recovers the major part of the elastic energy stored in the anchor and it thus undergoes an acceleration which leaves it a certain amplitude of oscillation, although less than that. which he presented before the shock.
