  • Patent number: 4286690
    Abstract: An escape device for allowing an individual to descend from a damaged building. A drum and cable is mounted in a housing. The free end of the cable is secured to a part of the building, allowing the user to descend as the cable plays out and the drum rotates. A multiple gear reduction train mounted to the drum automatically limits the descent speed. A coil spring shock absorber forms the connection between the drum and gear train to reduce shock. A strap is folded inside a separate compartment in the housing below the drum and gear train. The strap is placed about the user's body during the descent. A quick release door in the strap compartment provides access to the strap.
