ABSTRACT:
The invention is directed to a novel fire escape system designed for use with multi-story buildings. The system comprises a generally cylindrical (or other suitable geometric shape) vertical column, preferably attached vertically adjacent to the outside of the building, which is longitudinally slotted on one side to form a main descent channel and which has mounted within it a series of helical lead screws which are fitted together to form one continuous worm shaft.
A carrier seat (or harness) unit, which comprises, in part, a seat unit in the form of a net, a hook-up unit in the form of a ball or other suitable geometric shape, is adapted to readily engage within, and descend, at a controlled rate in, the above-mentioned apparatus.
People responding to a fire alarm will step through the leg opening in the seat unit and then place the hook-up unit of the carrier seat (or harness) unit, into the slotted channel of a feeder tube (exit lead unit) which extends from an area inside the window to the main descent channel adjacent the window.
The carrier seat unit, while carrying the person by means of the net, is then designed to slide, by gravity, through the feed tube and to the main column. The carrier unit then indexes in the main descent channel within the column and descends along the shoulders of the motor-driven rotating helical screw until it nears the bottom of the slot at which time appropriate means are provided for disembarkation. The orderly means of escape described above can be accomplished without the use of existing stairs or elevators.
