Abstract: An escape system (10) for lowering a user mounted thereon in a vertical direction (12) at a predetermined rate of descent responsive to a user applied force in predetermined areas on a seat member (22). The escape system (10) includes a mounting bar member (16) which extends in a longitudinal direction (18). The mounting bar member (16) is secured to a base surface (14) which may be a wall of an edifice, or some other vertically directed surface. A seat member (22) extends in the longitudinal direction (18) which provides containment or a seat for the user. A pair of first and second pulley members (32 and 34) are displaceably coupled to the seat member (22) through a rope element (36) passing between first and second pulley members (32 and 34) and cooperating with seat member (22). A lever bar member (50) is rigidly secured to each of the pulley members (30 and 32) and also extends in longitudinal direction (18) and actuates rotation of the pulley members (30 and 32) when the user applies force load on a first longitudinal end (24) of the seat member (22). Additionally, terminating rotation of the pulley members (30 and 32) is effected when the user applies a force load on the second end (26) of the seat member (22). In this manner, the user by shifting his or her weight can control the actuation of the rotation of the pulley members (30 and 32) and consequently the rate of descent in the vertical direction (12).
