Definitions

  • the present invention relates to a magnetic resonator for a mechanical timepiece, in particular for a wristwatch.
  • 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.
  • an element producing a permanent magnetic field whatever the form, that is to say that it may be constituted by a portion of material taken into the mass and having undergone a treatment in order to present the required magnetic properties, by an insert, or even by a deposited layer, of a suitable magnetic material.
  • Max Hetzel is at the origin of a large number of patented inventions, relating to the implementation of a tuning fork as an oscillator, which led to the production of the Accutron wristwatch (brand filed), 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.
  • the patent CH 594201 describes a dual oscillator resonator system.
  • the frequency stability of the oscillations of a tuning fork is advantageously used, by magnetic interaction, to stabilize the oscillations of a balance of conventional shape, thus 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.
  • the present invention relates more particularly to a resonator of the type mentioned above, characterized in that the escape wheel is free and carries at least two permanent magnets, preferably at least four, arranged in such a way that the vibrations of the tuning fork branch, on the one hand, control the rotational speed of the escape wheel and, on the other hand, are maintained periodically by the magnetic interaction between the first permanent magnet of the tuning fork and the permanent magnets of the escape wheel, to define a free escape.
  • the resonator according to the present invention offers the full benefits of the high quality factor of the tuning fork, that is to say without the nature of the exhaust collaborating with it attenuating these benefits, as it does. is the case of known mechanisms of the prior art.
  • the nature of the interaction retained between the tuning fork and the escape wheel, as well as the possibility of adjusting the properties magnetic permanent magnets used as required, allow to optimize the operation of the resonator according to the invention, in particular for the legs of the tuning fork exert a control of the speed of rotation of the escape wheel, by their vibrations, while by recovering from the latter the amount of energy sufficient to ensure the maintenance of their vibrations with excellent isochronism.
  • This magnetic interaction between the permanent magnets positioned on the escape wheel and the permanent magnet placed on one of the branches of the tuning fork, is of very small amplitude and of a very short duration. It intervenes only when one of the permanent magnets of the escape wheel is arranged opposite the magnet of the tuning fork. The interaction is only of magnetic nature, a space remaining between the two permanent magnets arranged face to face.
  • the arrangement of the magnets of the escape wheel associated with the magnet or magnets positioned on the branches makes it possible to maintain the free oscillations of the branches of the tuning fork. These free oscillations are natural natural oscillations.
  • An advantage of this type of resonator with regard to the state of the art is the reduction of oscillations disturbances.
  • the weak interaction of the magnets makes it possible to achieve a free escape.
  • the merit of the Applicant lies in having designed the resonator according to the present invention, against all odds, in which the amplitude of the magnetic interaction occurring between the tuning fork and the escape wheel is substantially greater than that intervening in the mechanisms based on the principle of reluctance, which appears a priori to be unfavorable from the point of view of isochronism, this increase of the amplitude being compensated by the implementation of a shorter time of the concerned interaction, ie free escape as opposed to known mechanisms, leading overall to a more favorable result.
  • the magnetic exhaust mechanical resonator according to the present invention has a simplified construction and assembly compared to conventional free exhausts such as Swiss anchor escapements or expansion exhausts.
  • the conventional mechanical free exhausts are particularly more complex in the adjustment of the relative positions of their constituents.
  • the resonator according to the present invention has neither ratchet system nor mechanical contact.
  • the durability of such a resonator is therefore greater than that of conventional mechanical resonators.
  • the escape wheel carries 2n permanent magnets, n being at least 1, preferably less than or equal to 40. These magnets are advantageously evenly distributed near the periphery or at the periphery of the escape wheel, to ensure a regular rotation of the latter.
  • two adjacent magnets of the escape wheel are arranged relative to each other to present to the magnet of the tuning fork, or to each magnet of the tuning fork, respective inverted polarities, when the wheel exhaust turns on itself.
  • the respective movements of the tuning fork leg and the escape wheel are synchronized in such a way that, when the tuning fork branch deviates from the escape wheel, the latter has a magnet giving rise to a repulsion in relation to the magnet of the branch, while, when the branch is close to the escape wheel, the latter has a magnet giving rise to an attraction in relation to the magnet of the branch.
  • the escape wheel can be arranged between the branches of the tuning fork, the second branch then being preferably provided with a second permanent magnet defining a second magnetic field.
  • the magnets of the tuning fork are preferably diametrically opposed with reference to the escape wheel.
  • the magnets of the escape wheel are advantageously arranged, in this case, in such a way that they are diametrically opposed to each other. two by presenting magnetic orientations such that they present interactions of the same nature with the magnets of the tuning fork.
  • Such a relative arrangement of the magnets makes it possible to ensure that the tuning fork oscillates according to its first mode of vibration, namely that its two branches move away from each other and approach each other simultaneously. .

  • the escape wheel may be located outside the branches of the tuning fork.
  • the mechanism according to the invention comprises a first escape wheel, associated with a first leg of the tuning fork for rotating with a first rotation speed, as well as a second transmission wheel. exhaust, associated with the other branch of the tuning fork, to rotate with a second speed of rotation.
  • one of the escape wheels may be associated with display members of the current time, while the other may be associated with short time display members, in particular by means of a chronograph type function.
  • FIG. 1 represents a simplified front view of a magnetic exhaust mechanical resonator, in a first configuration, comprising an escape wheel placed between the legs of a U-shaped tuning fork;
  • the figure 2 represents a simplified front view of the resonator of the figure 1 in a second configuration
  • the figure 3 represents a simplified front view of the resonator of the figure 1 in a third configuration

  • Figures 8a and 8b represent a simplified perspective view of a resonator according to a third embodiment variant.
  • FIGS. 1 to 3 illustrate, schematically and in a simplified manner, the operation of a tuning fork mechanical resonator according to a preferred embodiment of the present invention, in respective first, second and third configurations.
  • the resonator comprises a U-shaped tuning fork 1 having a pair of branches 2, 3 each of which carries a permanent magnet 4, 5 near its free end defining first and second magnetic fields.
  • Each magnet is disposed on its branch with its poles arranged in a direction substantially perpendicular to the longitudinal direction of the branch.
  • the magnets 4 and 5 are substantially aligned and oriented here in the same way, that is to say by presenting each other opposite poles.
  • An escape wheel 6 is schematically illustrated on the Figures 1 to 3 , this being arranged between the two branches 2 and 3 of the tuning fork 1.
  • the escape wheel 6 here carries six permanent magnets 61 to 66 regularly arranged at its periphery with their poles substantially aligned in radial directions. Two adjacent magnets of the escape wheel have opposite orientations, from the point of view of the magnetic field produced, with reference to the center of the escape wheel. In other words, two adjacent permanent magnets of the escape wheel are arranged relative to one another to present to a given magnet of the tuning fork, when the escape wheel rotates, respective reversed polarities when they are located in look at it.
  • the escapement wheel 6 is kinematically connected to a power source (not shown) via a conventional finishing train, with a predefined gear ratio and, the implementation of which will not pose no particular difficulty to the skilled person.
  • the escape wheel preferably carries an exhaust pinion arranged in engagement with a first mobile of the work train. Through this kinematic connection, the escapement wheel undergoes a permanent force tending to rotate it in a predefined direction of rotation (clockwise on the figures 2 and 3 ).
  • the escape wheel 6 and its magnets 61 to 66 are sized such that the latter are located within range of the magnets 4, 5 of the tuning fork, so that the magnetic fields of each other can interact.
  • the amplitude of the vibrations of its branches is of the order of 5 hundredths of a millimeter.
  • each of the magnets of the tuning fork alternately undergoes attractions and repulsions with reference to the escape wheel.
  • the escape wheel 6 is free to turn on itself, in the direction of clockwise rotation, as a consequence of the permanent force that it undergoes from the energy source of the corresponding timepiece. .
  • the tuning fork can advantageously be secured to the frame of a watch movement in a conventional manner, that is to say by an arm secured to the frame by a first end and from the point situated in the middle of the base 8 of the tuning fork by its other end.
  • the tuning fork vibrates according to its first vibratory mode, that is to say with its branches presenting exactly opposite displacements.
  • the two branches 2 and 3 deviate and move closer to each other.
  • the configuration illustrated on the figure 2 corresponds, at first, to a mutual approximation of the two branches 2 and 3.
  • the branches 2 and 3 of the tuning fork are attracted towards the wheel exhaust 6 defining a transfer of energy from the escape wheel to the tuning fork, aiming to maintain the vibrations of the latter.
  • the tuning fork acts as a magnetic brake on the escape wheel by slowing down its rotation induced by the force exerted by the energy source of the watch movement.
  • the escape wheel 6 continues its rotational movement at the same time, which brings it to its position of the figure 3 , while the branches 2, 3 are still in their phase of relative spacing.
  • the magnets facing each other have opposite polarities mutually, which results in the generation of a repulsive force between the branches 2, 3 of the tuning fork and the escape wheel.
  • This repulsion defines a new transfer of energy from the escape wheel to the tuning fork, aiming to maintain the vibration of the latter.
  • the escape wheel advances two steps during each complete oscillation of the tuning fork.
  • the frequency of the pitch of the escape wheel is double compared to the frequency of vibration of the tuning fork, whereas its frequency of rotation is of f / n Hz when it carries 2n permanent magnets, f being the frequency of vibration of the tuning fork.
  • the vibration frequency of the tuning fork can be adjusted according to the needs, in a conventional manner, in particular by modifying the distribution of the masses in its branches or its material.
  • the vibration frequency of the tuning fork present in the resonator according to the invention is substantially between 2 and 1000 Hz.
  • a vibration frequency higher than the oscillation frequencies of conventional balance wheels can, for example, be used in applications such as short time measurements.
  • the escape wheel must advance at least one hundredths of a second. It must therefore have a step frequency of 100 Hz (or a multiple of 100 Hz), which corresponds to a vibration frequency of the tuning fork of 50 Hz (or a multiple of 50 Hz).
  • Such operating frequencies can not be envisaged today in wristwatches using a spring-balance type oscillator for short and well-defined durations. Note that the realization of a mechanical exhaust operating at such frequencies is not without problems, especially in terms of wear.
  • the escape wheel Since the escape wheel is the end part of a mechanical gear train, it is preferable that it operates with a low frequency of rotation, for the same reasons of wear and mechanical simplicity. This is possible by providing a suitable number of magnets. By way of example, if twelve magnets are provided on the escape wheel, with a vibrating tuning fork at 50 Hz, the escape wheel rotates with a rotation frequency of 8.33 Hz, similar to that which it presents in known watch movements, while allowing the measurement of hundredths of a second.
  • the escape wheel carries 2n permanent magnets, n being at least 1, preferably less than or equal to 40.
  • These magnets are advantageously evenly distributed near the periphery or at the periphery of the escape wheel, to ensure a regular rotation of the latter.
  • the diameter of the escape wheel can influence the number of magnets that it comprises. Too many magnets is undesirable because it tends to give rise to a quasi-continuous interaction between the escape wheel and the tuning fork, detrimental to the isochronism of the resonator according to the invention.
  • escape wheel 6 may be arranged outside the tuning fork to cooperate with a single branch of the tuning fork, without departing from the scope of the present invention.

  • the escape wheels 40 and 50 are different from each other, in particular that they carry different numbers of permanent magnets, without departing from the scope of the present invention.
  • the gear ratios of the display gearings respectively associated with one and the other of the escape wheels may be different, in such a way, for example, that one is associated with the display. of the current time, while the other is associated with a chronograph function.

  • the figure 8b illustrates a position of the escape wheel 60 in which another of its magnets interacts with the tuning fork magnet to give rise to mutual repulsion.
  • the structure of the tuning fork is such that the magnetic interaction of only one of its branches with the escape wheel is sufficient to sustain its vibrations satisfactorily.
