    Background of the invention
    [0005] Most of today's mechanical watches include a Swiss lever escapement. The two main functions of the exhaust are:maintenance of the comings and goings of the resonator, constituted by a pendulum-balance assembly;Counting these back and forth.
    In addition to these two functions, the exhaust must be robust, and withstand shocks, and formed so as to avoid trapping the movement (overturning).
    The Swiss lever escapement has a low energy efficiency, of the order of 30%. This low yield is due to the fact that the movements of the exhaust are jerky, and that several parts are transmitted their movement via inclined planes that rub against each other.

    Detailed Description of the Preferred Embodiments
    The invention relates to a mechanical watch 200 provided with balanced resonators, out of phase and maintained continuously.
    The invention relates to a watch oscillator 1 comprising a structure 2 and / or a frame 4, and a plurality of primary resonators 10 and distinct.
    These primary resonators 10 are out of phase temporally and geometrically. They each comprise at least one inertial mass 5, which is biased towards the structure 2, or the frame 4, by an elastic return means 6. In effect, it is meant by "distinct resonators" that each primary resonator 10 has its own inertial mass. 5 and its own elastic return means 6, in particular a spring.
    According to the invention, this watch oscillator 1 comprises coupling means 11, which are arranged to allow the interaction of the primary resonators 10. These coupling means 11 comprise motor means 12, which are arranged to drive in motion a mobile 13. This mobile 13 comprises driving and guiding means 14, which are arranged to drive and guide, preferably in a prisoner manner, a control means 15. This control means 15 is articulated with a plurality of means 16, each articulated, away from the control means 15, with an inertial mass 5 of a primary resonator 10.
    In addition, the primary resonators 10 and the mobile 13 are arranged in such a way that the axes of the joints of any two of the primary resonators 10 and the axis of articulation of the control means 15 are never coplanar. In other words, the projections of these axes in a common perpendicular plane are never aligned. It is understood that the axes of articulation may, in some embodiments, be virtual pivot axes.
    In the non-limiting embodiments illustrated in FIGS. 1 to 9, the motor means 12 are arranged to drive the mobile 13 in a rotational movement about an axis of rotation A. In a particular variant embodiment, the driving and guiding means 14 consist of a groove 140 in which slides a finger 150 which comprises the control means 15. Preferably, this groove 140 is substantially radial with respect to the axis of rotation A of the mobile 13.
    It is understood that the mobile 13 is substituted for a conventional escape wheel, and is preferably downstream of a finishing gear powered by a barrel or the like.
    The transmission means 16 may in particular be made in the form of rods 160, each having a first hinge 161 with the control means 15, and a second hinge 162 with the inertial mass 5 considered. The first hinge 161 and the second hinge 162 together define a rod direction. According to the invention, all the rod directions are two by two, at any time, an angle other than zero or tt. Otherwise formulated, the vector product of the two directions of rods is different from zero.
    In a particular application, the transmission means 16 are non-collinear connecting rods 160. The mobile 13, subjected to a driving torque, and the coupling means 11 have an interaction geometry, which allows to essentially transmit tangential forces to these rods 160.
    Hereinafter elementary resonators are called resonators constituting a primary resonator together: they are mounted in tuning fork, so that the reactions and errors cancel each other out. When a number n of elementary resonators together constitute a primary resonator, they are out of phase with each other by 2π / n.
    FIG. 1 illustrates a general case of two elementary resonators 10A and 10B mass-spring type oscillating linearly and in different directions, and whose masses 5A and 5B are articulated to connecting rods 16A and 16B, which cooperate together in an articulated manner with a finger 150, which constitutes the control means 15, which runs through a groove 140 of a wheel constituting the mobile 13, the motor means being shown in FIG. 4 which shows a detail at the articulation of the connecting rods on the control means 15.
    In a particular preferred application, but not limited to, and illustrated by the figures, the primary resonators 10 are rotary resonators.
    Fig. 3 2 illustrates such an example, where the primary resonators 10A, 10B, are balance-spiral assemblies, where the spirals 6A, 6B are attached at their outer turn to the structure 2, and at their inner turn to the pendulums 5A 5B, which are articulated with ends 162A, 162B, of rods 16A, 16B, arranged similarly to those of FIG. 1.
    To obtain a better quality factor, the oscillator 1 is arranged so that the forces and the reaction couples of the primary resonators 10 on the support 2 (or on the frame 4 if they are all fixed on such a framework) cancel each other out. The forces cancel out because the center of mass does not move, when the axis of rotation passes through the center of mass. The pairs cancel each other because each component in rotation is compensated by another component in inverse rotation. The coupling between the resonators can be done via a flexible recess as in a tuning fork or via the connecting rods 160, or, more generally, the transmission means 16. The coupling of the primary resonators 10 with respect to each other is then performed by a flexible embedding of each of the primary resonators 10 with respect to the common structure 2 or to the frame 4.
    Thus, preferably, the resultant of the efforts and reaction torques of the primary resonators 10 with respect to the common structure 2 or the frame 4, to which they are attached, is zero.
    For optimum operation, the primary rotary resonators 10 are arranged so that their centers of mass remain in a fixed position, at least during the normal oscillations of these primary resonators 10. The watch oscillator 1 preferably comprises stop means for limiting their stroke in case of shock or the like.
    Preferably, these primary resonators 10 have at least one identical resonance mode, they are arranged to vibrate according to a phase shift between them of the value 2Tr / n, where n is their number, and they are arranged according to a symmetry in the space such that the resultant of the forces and torques applied by the primary resonators 10 on the structure 2, or on a frame 4 which supports them, is zero.
    In a particular application, as shown in the figures, the primary resonators 10 are even in number, and they constitute two by two pairs in which the inertial masses 5 are in phase shift of π with respect to the other.
    In a particular arrangement, as visible in FIGS. 3 and 5, at least one of the primary resonators 10 consists of a plurality of n elementary resonators 810. These elementary resonators 810 each comprise at least one elementary mass 805 carried by a flexible elastic elementary blade 806, constituting an elastic return means , and which is arranged to work in bending, and which is embedded in a cross 804.
    These elementary resonators 810 have at least one identical resonance mode, and are arranged to vibrate in a phase shift between them of the value 2π / n, where n is the number of elementary resonators 810. They are arranged according to a symmetry in the space, such that the resultant of the forces and torques applied by the elementary resonators 810 on the cross member 804 is zero.
    This cross member 804 is fixed to the fixed support 2 by an elementary main elastic connection 803, whose rigidity is greater than the rigidity of each elastic flexible elemental blade 806, and whose damping is greater than the damping of each blade elementary flexible 806. And the elementary resonators 810 are arranged in space so that the resultant of their operating errors due to gravitation is zero.
    More particularly, at least one of the primary resonators 10 consists of a pair of such elementary resonators 810. In this pair, the elementary inertial masses 805 are in phase shift of π relative to each other.
    More particularly, this pair consists of identical elementary resonators 810, which are geometrically opposite and phase relative to each other.
    In the particular case of FIGS. 3 and 5, each primary resonator 10 consists of such a pair of elementary resonators 810.
    In the variant of FIG. 3, each primary resonator 10A, 10B, thus forms, by the combination of two elementary resonators 8101, 8102, respectively 8103, 8104, an isochronous oscillator mechanism of tuning fork type said horns goat. A cross member 40A, respectively 40B, is fixed to the fixed support 2 by a main elastic connection 3A, respectively 3B, whose rigidity is greater than the rigidity of each resilient flexible blade 61A, 62A, respectively 61B, 62B. And the damping of this main elastic connection is greater than that of each flexible blade. These characteristics provide a coupling between the elementary resonators 8101 and 8102, respectively 8103 and 8104.
    For each primary resonator 10A, 10B, at least the main elastic connection 3A, respectively 3B, the cross member 40A, respectively 40B, the elastic flexible blades 61A, 62A, respectively 61B, 62B, together form a primary monolithic structure planar, silicon, or oxidized silicon, or quartz, or DLC, or the like, which, in the rest position of the isochronous oscillator mechanism 1, is symmetrical with respect to a plane of symmetry. Advantageously, the fixed support 2 forms a monolithic assembly with these two primary monolithic structures.
    The cross 40A, respectively 40B, carries a pair of masses 5, 51A and 52A marked, respectively 51B and 52B, mounted symmetrically on either side of the fixed support 2 and the main elastic linkage 3A , respectively 3B. Each of these masses is mounted oscillatingly and biased by an elastic flexible blade 61 A, 62A, respectively 61B, 62B, which is a spiral, or a spiral assembly. These spirals are each linked directly or indirectly to a mass at their inner turn, and attached to the cross 40A, respectively 40B, by its outer turn. Each mass pivots around a virtual pivot axis of position determined relative to the cross 40A, respectively 40B. Each virtual pivot axis is, in the rest position of the isochronous oscillator mechanism 1, coinciding with the center of mass, of the respective mass. The masses extend substantially parallel to each other in the rest position, in a transverse direction. To limit the displacement of the centers of mass to a transverse stroke relative to the crossbar 4, as small as possible in this transverse direction Y, and to a longitudinal race in a longitudinal direction (perpendicular to this transverse direction) which is greater than this transversal stroke, each spiral has a section or variable curvature along its development.
    The variant of FIG. 5, is a structure similar to that of FIG. 3, where each primary resonator 10A, 10B forms, by the combination of two elementary resonators 8101, 8102, respectively 8103, 8104, an isochronous oscillator mechanism of tuning fork type said in H. The flexible flexible blades 6: 61 A, 62A, respectively 61B, 62B, are no longer constituted by spirals, but by straight blades and short, that is to say a length less than the smallest value between four times their height or thirty times their thickness, this short blade characteristic for limiting the movements of the center of mass concerned, and arranged on either side of a cross 40A, respectively 40B, with which it forms the horizontal bar of an H whose masses form the vertical bars . Due to the symmetry and the alignment, the longitudinal arrangement of the elastic flexible blades makes it possible to compensate the direction of greater displacement of the centers of mass, which move symmetrically with respect to the plane of symmetry.
    Each primary resonator 10A, 10B, thus rendered isochronous by one of these particular combinations of elementary resonators, advantageously comprises rotational stops, and / or translational limit stops in the longitudinal and transverse directions, or / and translation limiting stops in a direction perpendicular to the two preceding ones. These stroke limiting means can be integrated, be part of a one-piece construction, and / or be reported. The masses comprise, advantageously, stop means arranged to cooperate with complementary abutment means that the sleepers 40A, 40B comprise, to limit the displacement of the resilient flexible blades relative to these sleepers, in case of shocks or similar accelerations .
    FIG. 5 also illustrates an advantageous variant where the transmission means 16A, 16B, are resilient flexible blades. It is then possible to make a monolithic assembly comprising the structure 2, the primary resonators 10 as described above, in particular complete, and these resilient flexible blades, and the finger 150.
    Figs. 6 and 7 illustrate variants where the connecting rods are beams having collars at both ends in place of the hubs. Fig. 6 illustrates a case of coupling two primary resonators, FIG. 7 of three such resonators. The transmission means 16 thus comprise at least one monolithic rod arranged to cooperate with both the control means 15 and at least two inertial masses 5 of as many primary resonators 10, and comprise at least one flexible neck at the of each articulation zone.
    Figs. 1, 2, 3 and 5 illustrate a clock oscillator 1 comprising two primary resonators 10.
    FIG. 8 illustrates a clock oscillator 1 comprising three primary resonators 10. This figure shows the application of the coupling of FIG. 7 to the inertial masses 5A, 5B, 5C, of the three primary resonators 10A, 10B, 10C.
    FIG. 9 illustrates a clock oscillator 1 having four resonators. These four resonators may be four primary resonators 10. They may also be four elementary resonators, constituting two by two primary resonators: one composed of the elementary resonators 10A and 10C, phase shifted by tt, the other of the elementary resonators 10B and 10D , also out of phase with π.
    Figs. 10, 12 and 13 illustrate a variant where at least one elastic return means 6 also constitutes a rotary guide, which avoids the friction inherent in the use of pivots.
    FIG. 10 shows a transmission means 16 constituted by a flexible blade, in the configuration of FIG. 9. This figure also shows angular stops: 71, 72, 710, 720, 76 on the mass 5, the respective complementary abutment surfaces 73, 74, 730, 740, 77 at the frame 4 on which is attached a short flexible blade 6, and an anti-shock abutment surface 75 on the mass 5, arranged to cooperate with a complementary surface 750 at the frame 4.
    In the variants shown, the motor means 12 are arranged to drive the mobile 13 in a rotational movement, and the mobile 13 and the drive and guiding means 14 are arranged to apply to the control means 15 a force substantially tangential to the rotation of the mobile 13.
    FIG. 11 illustrates a variant where the mobile 13 comprises a resilient structure 130 deformable, forming a radially rigid and rigid guide tangentially, this deformable structure 130 comprises a housing 140 for cooperating with the finger 150 of the control means 15 at the main joint.
    In the various variants described herein, preferably the elastic return means 6 of the primary resonators 10 comprise flexible blades, and the primary resonators 10 and / or the common structure 2, and / or the frame 4, comprise stops. radial and / or angular and / or axial arranged to limit the deformations of the flexible blades and to prevent breakage in case of shocks or motor torque too high.
    In an advantageous embodiment, the watch oscillator 1 comprises a monolithic structure which groups together a common structure 4 towards which the inertial masses 5 are recalled by their elastic return means 6, the control means 15 and its articulations with the means transmission 16, and the transmission means 16 with their joints to the inertial masses 5.
    [0054] Advantageously, this monolithic structure also comprises the stops.
    Preferably, the orientation of the elastic return means 6 of the primary resonators 10 is optimized so that the operating errors due to gravity vanish between the primary resonators 10.
    In a variant not shown, the elastic return means 6 of the primary resonators 10 are cross-leaf virtual pivots.
    In a particular variant of the watch oscillator 1 according to the invention, the primary resonators 10 are isochronous.
    The advantages of the invention are numerous:a grooved wheel, unlike an elastic link on a crank, does not add a parasitic biasing force to the resonators when the amplitude changes. It follows a better isochronism;the use of rotary resonators whose center of rotation coincides with the center of mass prevents the center of mass from moving in the gravitational field, and thus avoids that the period is affected by a change of orientation of the shows. The same argument explains that our system is less affected by shocks in translations.preferably, the resonators are all identical and connected in parallel. The movements of one are not likely to interfere with the inertia of the other, unlike series editing;the use of two or more completely distinct resonators, that is to say with an inertial mass specific to each primary or elementary resonator, makes it possible to optimize the isochronism of the resonators separately, and to play on their orientation for that positional errors and flush responses cancel each other out. This is a great advantage to obtain an oscillator independent of the positions of the watch, and having a very high quality factor.the design allows a very simple manufacture of the integrated version;the invention allows achievements in the purest watchmaking tradition since one can simply use two sprung balance assemblies connected to the escape wheel by very light rods or flexible blades.
