It is, in a way, to combine the respective advantages of known mechanisms using as resonator, or a balance-spiral assembly relatively insensitive to differences in position in space in its developments and most advanced montages but whose quality factor is strongly limited by the pivoting and the different losses, or a tuning fork with parallel blades which, free of pivoting, has a quality factor better than a sprung balance but is very sensitive to the position in space.

  • the Figures 1 to 17 illustrate examples with two primary resonators
  • the figure 19 illustrates an example with four primary resonators.

  • the main elastic connection 3 is straight.
  • the resilient flexible blades 6 are straight in the longitudinal direction X.
  • the centers of mass CM of the primary resonators 10 are considered in their alignment at rest. This arrangement guarantees the insensitivity to the positions of the isochronous oscillator mechanism 1 according to the invention, unlike a tuning fork of the conventional type with parallel branches which is much too sensitive to the positions in space if it is incorporated in a watch, and which can only be suitable for a piece of clock.
  • the residual defect after compensation of the displacements of the centers of mass in X is of very small value, of the same order of magnitude as the defect due to displacements of the centers of mass in Y, which is limited to 3 or 4 micrometers, for a blade of 1 mm long, the cumulative defect thus remains less than 6 seconds per day.

  • the crossbar 4 carries a pair 51, 52, masses 5, mounted symmetrically inside the crossbar 4 which forms a frame suspended by the first elastic connection 3 to the fixed structure 2, the masses 51, 52 extending substantially in the transverse direction Y.
  • Each of the masses 51, 52 is oscillatingly mounted around a virtual pivot axis of position determined relative to the crossbar 4, and recalled by an elastic flexible blade 6, respectively 61, 62, which is secured to one side of the frame forming the crossbar 4, the flexible blades 61, 62, extending linearly to the inside the frame.
  • FIG 21 illustrates, in this variant of crossbar 4 formed by a frame, adjacent to the invention, the pendulum fork horns goat.

  • Each of the masses 51, 52 is oscillatingly mounted about a virtual pivot axis of position determined with respect to the crossbar 4, and recalled by a spiral 8, respectively 81, 82, which is integral with one side of the frame forming the crossbar 4, these spirals 81, 82, extending inside the frame.
  • the masses 5, 5A, 5B, 51, 52, form rockers.
  • the masses 51, 52 comprise, for balancing adjustment, inertia and adjustment of oscillation frequency, flyweights 91, 92, and / or housing 93 for receive such flyweights, preferably in the areas farthest from the ends 41, 42 of the crossbar 4.
  • flyweights advantageously comprise an eccentric insert, for example platinum, to facilitate adjustment by pivoting the insert.

  • each primary resonator 10 is designed to minimize the displacement of the center of mass CM in the transverse direction Y of the symmetry plane PS of the tuning fork.
  • the symmetry plane PS of the tuning fork is chosen so that the operating errors due to the positions in the longitudinal direction X perpendicular to the transverse direction Y, cancel out between the two branches of the tuning fork constituted by the primary resonators 10, both sides of the crossbar 4.
  • tuning fork type limits the effect of reactions to embedding.
  • the invention minimizes the displacement of the center of mass CM of each primary resonator 10.
  • the invention makes it possible to obtain a perfectly isochronous oscillator, very compact, requiring no adjustment other than the inertia of the masses, and very easy assembly.
