Abstract

Mécanisme d'échappement pour l'entretien des oscillations d'un balancier (3) d'une pièce d'horlogerie comportant un bâti; ce mécanisme d'échappement comportant une roue d'échappement (1.2) et un plateau (7), solidaire d'un axe de balancier (3) comportant une cheville d'impulsion (7.7). Ce mécanisme d'échappement comporte encore:
- un mobile d'impulsion (2) pivoté sur le bâti du mouvement d'horlogerie comportant une fourchette d'impulsion (2.3) coopérant avec la cheville d'impulsion (7.7); un ressort d'impulsion (2.4); et un bras (2.5) terminé par un crochet (2.6) coopérant avec la roue d'échappement (1.2); et
- des moyens de pilotage (5, 6, 7.6, 7.10) libérant la roue d'échappement (1.2) d'un pas pendant des premières alternances du balancier (3), et dégageant le crochet (2.6) du mobile d'impulsion (2) de la roue d'échappement (1.2) pendant des secondes alternances du balancier (3).

Figure imgaf001
Exhaust mechanism for the maintenance of the oscillations of a pendulum (3) of a timepiece comprising a frame; this escapement mechanism comprising an escape wheel (1.2) and a plate (7), integral with a balance shaft (3) comprising a pulse pin (7.7). This escape mechanism also includes:
- a pulse wheel (2) pivoted on the frame of the clockwork comprising a pulse fork (2.3) cooperating with the pulse pin (7.7); a pulse spring (2.4); and an arm (2.5) terminated by a hook (2.6) cooperating with the escape wheel (1.2); and
- control means (5, 6, 7.6, 7.10) releasing the escape wheel (1.2) of a pitch during first half-waves of the pendulum (3), and releasing the hook (2.6) of the impulse mobile ( 2) of the escape wheel (1.2) during second alternations of the balance (3).
