Abstract

A safety gear designed to be mounted on an elevator car (1) moving along guide rails (7), comprising a frame (4), an area of wedge housings (3d,6d) formed in the frame, and wedges (3,6) placed in the wedge housings on each side of the guide rail (7), said wedges gripping the guide rail when the safety gear is activated, the wedges being so placed relative to each other that the wider end of one wedge (3) points upwards while the wider end of the other wedge (6) points downwards. To allow safety gear action in both upward and downward directions, the safety gear is provided with an activating means (10) connected to and moving both wedges, and an overspeed governor or equivalent for controlling the activating means.
