Title (EN) FLEXIBLE ESCAPEMENT MECHANISM HAVING A PLATE-FREE BALANCE
(FR) MÉCANISME D'ÉCHAPPEMENT FLEXIBLE À BALANCIER SANS PLATEAU
Abstract: front page image
(EN)The invention relates to an escapement mechanism (120) for a timepiece, comprising a plate-free balance (300) and an escapement wheel (400) between which the transmission of pulses is carried out via a unitary flexible mechanism (500) connected, via at least one flexible blade (700), to a stationary structure (800) or to said wheel (400). The oscillation is sustained by a hairspring (121) ending in a stud (122) which is mobile during operation, which is guided by a flexible guide (123) having flexible blades (124), and the center of rotation (125) of which is coaxial to said balance (300), wherein said stud (122) receives a pin (127) that is mobile along a cam path (128) of said wheel (126). During the oscillations, said stud (122) moves relative to the rest position thereof due to the force exerted by said hairspring (121), and said pin (127) sustains and adjusts the oscillation.
(FR)Mécanisme d'échappement (120) d'horlogerie comportant un balancier (300) sans plateau et une roue d'échappement (400), entre lesquels la transmission d'impulsions est réalisée par un mécanisme flexible monobloc (500) relié par au moins une lame flexible (700) à une structure fixe (800), ou à ladite roue (400). L'entretien de l'oscillation est effectué par un ressort-spiral (121) terminé par un piton (122) mobile durant le fonctionnement, et qui est guidé par un guidage flexible (123) à lames souples (124), et dont le centre de rotation (125) est coaxial audit balancier (300), ledit piton (122) recevant une cheville (127) mobile dans un parcours de came (128) de ladite roue (126). Lors des oscillations, ledit piton (122) se déplace par rapport à sa position de repos sous l'action de la force exercée par ledit spiral (121), et ladite cheville (127) entretient et régule l'oscillation.
