Abstract

Mouvement pour pièce d'horlogerie présentant une fonction chronographe et comportant notamment un compteur de secondes (11), ainsi que des moyens d'entraînement (10,14) et des moyens de blocage (40) sélectifs de ce compteur de secondes, destinés à être actionnés au moyen d'un organe de commande extérieur. Le mouvement comporte également des moyens de remise à zéro (30,34) également destinés à être actionnés par un organe de commande extérieur pour être déplacés entre une position de repos et une position active. Le mouvement de chronographe comprend en outre un levier de dégagement (45) remplissant une pluralité de fonctions dont, la neutralisation des moyens de blocage lors des phases d'activation des moyens de remise à zéro, ou encore, le verrouillage de l'organe de commande extérieur destiné à actionner les moyens de remise à zéro (30,34) lors des intervalles de mesures de temps.

Movement for a timepiece having a chronograph function and comprising in particular a seconds counter (11), as well as drive means (10, 14) and selective blocking means (40) for this second counter, for be actuated by means of an external control member. The movement also comprises reset means (30,34) also intended to be actuated by an external control member to be moved between a rest position and an active position. The chronograph movement further comprises a release lever (45) filling a plurality of functions including, the neutralization of the locking means during the activation phases of the resetting means, or the locking of the locking member. external control for actuating the reset means (30,34) during the time measurement intervals.
