Definitions

  • the present invention relates to a tuning fork mechanical resonator for a free escapement mechanical clock movement, comprising a tuning fork type oscillator, of which at least a first oscillating branch is intended to oscillate on either side of a first axis and carries at least a first pin associated with at least one first fork tine of an anchor, for pivoting the latter between first and second angular positions and alternately lock and release an escape wheel.
  • such a mechanism makes it possible, in relation with a source of mechanical energy, to maintain oscillations of the oscillator which is the tuning fork and thus to define a resonator.
  • the high quality factor of an oscillator as a tuning fork makes it attractive in the context of a watch application.
  • the present invention also relates to a watch movement provided with such a resonator and a timepiece, in particular but not exclusively of the wristwatch type, equipped with such a watch movement.
  • the patent FR 73414 A issued in the name of Louis-Institut-Clis Breguet on the basis of a request filed in 1866, describes a pendulum whose mechanical oscillator is a tuning fork.
  • a first branch of this tuning fork carries an anchor having two arms arranged to cooperate with an escape wheel, to alternately lock and release the latter.
  • the anchor does not rotate on the frame of the watch movement, as is usually the case, but has the same oscillating movement as the end of the branch of the tuning fork that carries it.
  • the escapement designed is not free type, since, on the one hand, the anchor has a permanent contact with the escape wheel and, on the other hand, the anchor ensures the attachment of the anchor on the branch of the tuning fork and therefore never leave the anchor.
  • Such an exhaust therefore has the corresponding disadvantages, namely greater wear and chronometric disruption than a free exhaust.
  • Max Hetzel is at the origin of a large number of patented inventions, relating to the implementation of a tuning fork as oscillator, which led to the production of the wristwatch.
  • Accutron (registered trademark) bracelet marketed by Bulova Swiss SA.
  • the Accutron watch however includes an electronic resonator since each branch of the corresponding tuning fork carries a permanent magnet associated with an electromagnet mounted fixed on the frame of the watch.
  • the operation of each electromagnet is controlled by the vibrations of the tuning fork, by means of the magnets which it carries, in such a way that the vibrations of the tuning fork are maintained by the transmission of periodic magnetic pulses from the electromagnets to the permanent magnets.
  • One of the branches of the tuning fork actuates a pawl for rotating the mobile wheels of the finishing gear of the watch. This construction does not lend itself to the use of the ratchet to ensure the maintenance oscillations of the tuning fork.
  • the patent CH 594201 describes a dual oscillator resonator system.
  • the frequency stability of the oscillations of a tuning fork is exploited, by magnetic interaction, to stabilize the oscillations of a balance of conventional shape, therefore having a lower quality factor than that of the tuning fork.
  • the branches of the tuning fork, on the one hand, and the balance, on the other hand carry permanent magnets arranged to cooperate with each other. The corresponding interaction makes it possible both to maintain oscillations of the tuning fork and to stabilize oscillations of the pendulum in frequency.
  • this mechanism is necessarily coupled to a mechanical escapement to convert the periodic oscillation of the balance into a unidirectional movement to ensure the drive of the mobile of a cog finishing.
  • the balance is coupled to a conventional mechanical escapement arranged to maintain the oscillations. Consequently, the mechanism described in this document makes it possible to improve the frequency stability of the oscillations of a balance wheel, but this is done at the cost of a complexity and a much larger space requirement compared to a conventional one-way mechanism. oscillator.
  • the high quality factor of the tuning fork is only partially used in the solution presented since, in the end, it is the pendulum which controls the movements of the finishing gear train, in a similar way to what is being done. works in classical systems.
  • a main object of the present invention is to overcome the disadvantages of tuning fork resonators known from the prior art, by proposing a resonator for a mechanical timepiece, in particular for a wristwatch, having a quality factor and isochronism high as well as an escapement of free type.
  • the frequency of the oscillations of a tuning fork is much greater than that of a balance-spring.
  • the aforementioned Accutron has its tuning fork that vibrates at a frequency of 360Hz, compared to the 4Hz balance springs of most current mechanical watches.
  • the adaptation of a conventional free escapement so that it operates in relation to a tuning fork is not obvious.
  • the higher vibration frequency of the tuning fork should result in greater energy expenditure and component wear than with a sprung balance.
  • the amplitude of the vibrations of a clock tuning fork is small.
  • the amplitude of the tuning fork vibrations of the Accutron is 0.036mm, compared to the amplitude of oscillations of the balance peg in a balance spring system, of the order of 2mm.
  • the higher operating frequency and the reduced amplitude imply that the corresponding exhaust should act on a larger portion of the oscillation of the tuning fork and the exhaust perturbation should therefore be greater than in the conventional case.
  • a further problem is that the oscillatory movement of the blades or branches of the tuning fork is almost linear, compared to the circular movement of the balance. Thus, the axial displacement of the end of the branch of a tuning fork is very small.
  • the lateral amplitude of the oscillations of a tuning fork branch is capable of strongly varying, up to 50% by average value according to Max Hetzel. Because of this variation, the ankle must be able to move out of the fork so as not to be disturbed during an additional arc greater than the average, that is to say to ensure that the vibration of the oscillator is free during the additional arc, a necessary condition for the realization of a free escape. We must therefore solve the difficulty related to the problem of entry and exit of the ankle with reference to the anchor fork.
  • the implementation of a tuning fork in a wristwatch involves a problem in terms of size.
  • the tuning fork used in the Accutron model has a length of 25mm, compared to the current diameter of a pendulum, of the order of 10mm.

  • the plateau pin integral with the oscillator and actuating the anchor to disengage the escape wheel, has a displacement amplitude axial, considering here the axis of the anchor when it is oriented towards the axis of the balance, greater than that of the anchor.
  • the oscillator is a tuning fork
  • the amplitude of the axial displacements of the ends of its blades is insufficient to ensure the entry of the anchor into the anchor fork, as well as its exit out of the fork.
