Abstract

A device is provided for controlling the motion of a movable member such as a sliding door. The device comprises two springs. Each spring has its own catch for releasably holding it in a pre-loaded condition. The catches are releasable by motion of the door to apply force to its closing movement. The catches are arranged so that one of the springs will exert force on the door before the other.
