Title (EN) ROTARY RESONATOR WITH A FLEXIBLE GUIDE SYSTEM BASED ON A DETACHED LEVER ESCAPEMENT
(FR) RESONATEUR ROTATIF A GUIDAGE FLEXIBLE ENTRETENU PAR UN ECHAPPEMENT LIBRE A ANCRE
Abstract:
(EN) Timepiece regulating member (300) comprising a detached escapement mechanism (200) with a lever (7) and a resonator (100) having a Q quality factor, comprising an inertial element (2) with a pin (6) rigidly secured to the inertial element (2) and interacting with a fork (8) of the lever (7), the inertial element (2) being acted upon by elastic return means (3) fastened directly or indirectly to the plate (1) and being arranged to interact indirectly with an escapement wheel (4) that is part of the escapement mechanism (200); the resonator mechanism (100) is a rotary resonator with a virtual pivot, pivoting about a main axis (DP), and has a flexible guide system subjected to the elastic return of at least two flexible blades (5) fastened to the plate (1), together defining a virtual pivot with a main axis (DP), the lever (7) pivoting about a secondary axis (DS).
(FR) Régulateur (300) d'horlogerie, comportant un mécanisme d'échappement (200) libre à ancre (7), et un résonateur (100) de facteur de qualité Q comportant un élément inertiel (2) comportant une cheville (6) solidaire d'un élément inertiel (2) et coopérant avec une fourchette (8) de l'ancre (7), cet élément inertiel (2) étant soumis à l'action de moyens de rappel élastique (3) fixés directement ou indirectement à la platine (1) et étant agencé pour coopérer indirectement avec un mobile d'échappement (4) que comporte le mécanisme d'échappement (200), ce mécanisme résonateur (100) est un résonateur rotatif à pivot virtuel, autour d'un axe principal (DP), à guidage flexible soumis au rappel d'au moins deux lames flexibles (5) fixées à la platine (1), définissant ensemble un pivot virtuel d'axe principal (DP), l'ancre (7) pivotant autour d'un axe secondaire (DS).
