ABSTRACT:
A fire escape device incorporated into new buildings or added on to existing buildings by which occupants of the building may quickly and safely exit from the building in the case of fire or other emergency conditions. The fire escape device includes a vertical track or guide that slidably receives a slide in the form of a backpack attached to each person using the fire escape device. The slide or backpack includes an oscillatable control member that swings back and forth about an axis perpendicular to the track or guide and engages a plurality of stationary pins oriented in staggered spaced relation on opposite side of the guide or track and control members that control the speed of descent of the slide or backpack and the individual supported thereon. An interlock device is provided to control access to the track or guide to insure proper sequential use of this fire escape device by a plurality of individuals. The lower end of the fire escape device includes an angulated discharge chute or ramp or transversely aligned control pins to stop the slide or backpack just prior to reaching a bottom support surface to enable a person to safely use the fire escape device. The arrangement of the components also will stop succeeding users until the lower most user has exited from the fire escape device.
