Abstract
The present invention contemplates a descent device including a roller having an annular groove about its contact surface, a support structure to which the roller is rotatably attached, a pinion gear rotatably attached to the support structure, a rotor disk directly coupled to the pinion gear, a braking device coupled to the support structure for controlling the speed of rotation of the rotor, a hand held actuator for activating the brake device, and a sling attached to the support structure capable of supporting a person who can control his or her descent by actuating the brake device, enabling a person to escape from a building during emergency conditions. The present invention also contemplates the combination of the above-described descent device and a vertically extending rail-like support track which is fixedly secured to the exterior of a building wall. The track is shaped substantially like an I-beam in which one edge of the I-beam includes a plurality of recesses and projections to form a rack designed to correspond with the pinion gear of the descent device, while the other edge of the I-beam is straight and smooth and is designed to correspond with the roller whose contact surface contacts the smooth edge.
