ABSTRACT:
A fire escape in the form of an elongated flexible member anchored at its upper end to a building structure or stationary device associated with the building structure with the flexible member being of sufficient length to reach the ground or some other lower level by which a person may safely escape from a fire in the building. An attachable and detachable slide is mounted on the flexible member for longitudinal sliding movement in relation thereto with the rate of descent being manually controlled by a person supported therefrom by a belt type sling. The slide includes a pair of hingedly attached members having partial grooves in their facing surfaces for engaging the flexible member and a screw-threaded bolt and nut assembly connecting the hingedly connected members for moving the facing surfaces toward and away from each other for varying the frictional engagement between the slide and the flexible member. The attachable and detachable slide facilitates a plurality of individuals escaping from the same building enclosure on a single flexible member. The slide includes a hook thereon over which the lower portion of the flexible member may be entrained so that a person on the ground may control descent of the slide by tensioning the flexible member.
