Claims (5)

Description [0001] On connaît, tel que visible sur lafig. 1, un résonateur 10 de type rotatif issu de la mise en série de deux oscillateurs 01 et 02 à guidage flexible comportant chacun une masse M1, M2, celle M1 du premier oscillateur 01 étant suspendue par des premières lames flexibles L1 à une structure fixe P telle qu’une platine. Le premier oscillateur 01 oscille essentiellement selon une première direction linéaire Y. La première masse mobile M1 de ce premier oscillateur 01 sert d’ancrage aux deuxièmes lames flexibles L2 d’un deuxième oscillateur 02, qui oscille essentiellement selon une deuxième direction linéaire X, perpendiculaire à la première direction linéaire Y. La deuxième masse mobile M2 du deuxième oscillateur 02 comporte une goupille 2, qui coopère avec une rainure 1 que porte un mobile 3 soumis à un couple, typiquement une roue d’échappement. [0002] Les forces de rappel ne sont pas exactement proportionnelles aux déplacements, car les guidages flexibles L1, L2 utilisés dans un tel résonateur sont très courts, ce qui entraîne une non-linéarité de la force du ressort en fonction du déplacement, ce qui introduit un défaut d’isochronisme. [0003] Pour rendre le système isochrone, on agence de façon particulière la rainure 1 qui sert de guidage à la goupille 2 fixée sur la deuxième masse M2 du deuxième oscillateur 02. [0004] Selon l’invention, on donne à cette rainure 1 une forme créant une force radiale, qui corrige la variation de la constante du ressort des lames du guidage flexible. [0005] Cette force peut être dirigée vers le centre ou vers l’extérieur, en fonction de la forme de la rainure. [0006] Une première exécution est une rainure entièrement courbe, tel que visible sur la fig. 2. [0007] Dans une variante avantageuse, la concavité de cette rainure 1 décroit progressivement depuis l’axe de rotation du mobile porteur de cette rainure. [0008] Une deuxième exécution, tel que visible sur la fig. 3, est une rainure 1 comportant une première partie intérieure radiale par rapport à l’axe de rotation D du mobile 3 porteur de cette rainure 1, qui est tangente à une deuxième partie courbe de concavité constante ou décroissante en s’éloignant de cet axe de rotation D de façon à compenser les défauts d’isochronisme. [0009] Dans une autre variante, la rainure 1 est droite mais non radiale. [0010] Ainsi l’invention concerne un mobile 3 d’application d’un couple à un résonateur 10 comportant un premier oscillateur 10 linéaire selon une première direction Y par rapport auquel oscille un deuxième oscillateur 20 linéaire selon une deuxième direction X orthogonale à ladite direction Y, ledit deuxième oscillateur 20 comportant une deuxième masse M2 porteuse d’une goupille 2 coopérant sans jeu avec une rainure 1 comportant au moins une partie courbe. [0011] L’invention concerne encore un tel résonateur 10 équipé d’un tel mobile 3 avec une rainure 1 telle que décrite ci-dessus, un mouvement équipé d’un tel résonateur, une montre équipée d’un tel mouvement. RevendicationsDescription [0001] As is known from LaFig. 1, a resonator 10 of rotary type from the series connection of two oscillators 01 and 02 with flexible guide each having a mass M1, M2, the M1 of the first oscillator 01 being suspended by first flexible blades L1 to a fixed structure P such as a platinum. The first oscillator O1 oscillates essentially in a first linear direction Y. The first mobile mass M1 of this first oscillator O1 serves to anchor the second flexible blades L2 of a second oscillator O2, which oscillates essentially in a second linear direction X, perpendicular at the first linear direction Y. The second mobile mass M2 of the second oscillator O2 comprises a pin 2, which cooperates with a groove 1 which carries a mobile 3 subjected to a torque, typically an escape wheel. The restoring forces are not exactly proportional to the displacements, because the flexible guides L1, L2 used in such a resonator are very short, resulting in a non-linearity of the force of the spring as a function of displacement, which introduces a defect of isochronism. In order to make the isochronous system, the groove 1 which serves as a guide for the pin 2 fixed on the second mass M2 of the second oscillator 02 is arranged in a particular way. [0004] According to the invention, this groove 1 is given to this groove 1 a shape creating a radial force, which corrects the variation of the spring constant of the blades of the flexible guide. This force can be directed towards the center or towards the outside, depending on the shape of the groove. A first embodiment is a fully curved groove, as shown in FIG. 2. [0007] In an advantageous variant, the concavity of this groove 1 decreases progressively from the axis of rotation of the mobile carrier of this groove. A second embodiment, as shown in FIG. 3, is a groove 1 having a radial first inner portion with respect to the axis of rotation D of the mobile 3 carrying the groove 1, which is tangential to a second curve portion of constant concavity or decreasing away from this axis rotation D to compensate for isochronism defects. In another variant, the groove 1 is straight but not radial. Thus the invention relates to a mobile 3 for applying a torque to a resonator 10 having a first linear oscillator 10 in a first direction Y relative to which oscillates a second linear oscillator 20 in a second direction X orthogonal to said direction Y, said second oscillator 20 having a second mass M2 carrying a pin 2 cooperating without play with a groove 1 having at least one curved portion. The invention also relates to such a resonator 10 equipped with such a mobile 3 with a groove 1 as described above, a movement equipped with such a resonator, a watch equipped with such a movement. claims 1.
