ABSTRACT:
A highrise fire escape device gravity operated and particularly adaptable for use in highrise building and modern skyscraper structures as an escape apparatus from any floor of a building for use in the rescue of an occupant who may be trapped and prevented from using the conventional stairways or elevator due to a natural or man-made disaster such as fire, electrical or power failure, building collapse or personal injury of the occupants, etc.
The apparatus or device comprises the combination of a vertical skid track member attached to the wall of a building with a skid which is inserted into a guide channel located in the track. The skid track is designed to be attached to either a new or existing building with access to the skid track being available at the outside of the building at predetermined locations, such as, building corners or a plurality of locations intermediate to the corners between the building windows so as not to impede the architecture design of the building. The skid track has a back and guide portion with a plurality of spring loaded or hinged skid track doors which allows the insertion of a skid to which the occupant of a building may be attached. The skid is so designed to allow its movement down the vertical skid track with the occupant attached, with its rate of descent being controlled by a plurality of descent retarders suitably disposed along the skid tracks entire length. The descent retarder is disposed within the back section of the skid track and partially protrudes into the guide channel of said track. As the skid moves down the guide channel of the skid track it comes into fractional contact with the biased plane frictional surface of the plurality of protruding descent retarders disposed along its vertical axis causing the descent retarder to be displaced in a horizontal direction perpendicular to direction of the skid movement. The movement of the descent retarders in a horizontal direction is resisted by means just as a plurality of springs interposed between the rear of the descent retarders and the inside the back portion of the skid track. While the majority of the descent retarders are spaced uniformly along the entire length of the vertical skid track, there are some that are placed in a closer or cluster configuration near the end of the vertical skid track to more greatly impede the rate of descent or velocity of the occupant user so as to prevent forceful contact with the ground. During an emergency, a building occupant may put on a harness of any standard construction and attach it to the skid which can easily be inserted into the guide portion of the vertical skid track through any of the plurality of track doors disposed along said skid track.
