Abstract

L’invention concerne un régulateur de vitesse (30) d’un ascenseur comportant un câble de régulateur (6) enroulé autour de poulies de régulateur. Le régulateur (30) comprend : un socle (1) ; une poulie de régulateur (2) montée dans le socle (1) sur un arbre rotatif (3) et entraînée en rotation par actionnement du câble de régulateur (6) enroulé autour d’elle ; une masselotte (8) montée sur une face latérale de la poulie de régulateur (2) et dotée d’une griffe rotative (13) ; et un rochet rotatif (12) formé sur l’arbre rotatif (3) et susceptible de s’encliqueter sur la masselotte (8). Un levier d’inspection rotatif (42) est monté sur le socle (1) au moyen d’une broche rotative (41) placée à l’extérieur de la griffe (13) ; et un fil (43) est rattaché au levier d’inspection (42) pour l’entraîner en rotation. Une force de traction appliquée au fil (43) entraîne le levier d’inspection (42) en rotation pour comprimer la griffe (13) et l’encliqueter sur le rochet (12).
