  • Patent number: 5826678
    Abstract: A fire escape parachute is provided and includes a center shaft, top ribs, stretcher ribs, a main runner, reinforcing ribs, an upper runner, a fabric and a safety belt. The function of the runner is to drive the stretcher ribs which in turn push the top ribs to open the fabric. The reinforcing ribs will tightly pull the outer ends of the top ribs, so that the top ribs are bent downwards to form an arc and such is secured by reinforcing ropes to effectively prevent reverse upward turning of the fabric and the top ribs. Thus, in case of fire in a high-rise building, the fabric can be controlled and opened directly by the escapee, who will use the fire escape parachute to slowly descend from the high-rise building.
