Abstract

Cet échappement comprend un balancier (3), une roue d'échappement (1), une bascule de détente (4) présentant un élément d'arrêt (4a) et un élément de dégagement élastique (4c), des moyens pour engager l'élément d'arrêt dans la trajectoire de la denture de la roue d'échappement (1), et un doigt de dégagement (7) solidaire en rotation du balancier (3) pour venir en prise avec l'élément de dégagement élastique (4c) de la bascule (4) une fois par période d'oscillation du balancier. Les moyens pour engager l'élément d'arrêt (4a) dans la trajectoire de la denture de la roue d'échappement (1) comportent une surface de glissement (4b) solidaire de la bascule de détente (4), disposée pour pénétrer dans la trajectoire de la denture de la roue d'échappement (1) lorsque l'élément d'arrêt (4a) en sort, cette surface de glissement étant conformée pour replacer l'élément d'arrêt (4a) en position de verrouillage.

This escapement comprises a rocker (3), an escape wheel (1), a trigger rocker (4) having a stop member (4a) and an elastic release member (4c), means for engaging the stop element in the path of the toothing of the escape wheel (1), and a release finger (7) integral in rotation with the rocker (3) to engage with the elastic release element (4c) of the rocker (4) once per oscillation period of the pendulum. The means for engaging the stop element (4a) in the path of the toothing of the escape wheel (1) comprise a sliding surface (4b) integral with the trigger rocker (4), arranged to penetrate the trajectory of the toothing of the escape wheel (1) when the stop element (4a) comes out of it, this sliding surface being shaped in order to replace the locking element (4a) in the locking position.
