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.

An emergency escape apparatus, which comprises: a plurality of modular column sections, each of which are axially aligned and mounted essentially contiguous to each other, to form a main column, each of said column sections having a slot along one side, said slots being maintained in a constant alignment whereby said aligned slots form a descent channel within said main column, said descent channel extending parallel to the longitudinal axis of said main column; a plurality of modular helical lead screw sections, each of which are axially aligned and mounted, essentially contiguous, to each other, to form a worm shaft, said worm shaft being generally centrally located, and rotatable, within said main column and extending parallel to the longitudinal axis of said main column; motive power means for rotating said worm shaft; at least one exit lead unit extending laterally to said main column, from an area adjacent said main column, and adapted to merge with said main column, said exit lead unit being slotted longitudinally along one side to form a feeder slot merging into said descent channel; a carrier means having a hook-up unit affixed thereto, said hook-up unit being adapted to ride within said feeder slot in said exit lead unit and, thence, ride within said descent channel in said main column, whereby as said worm shaft is rotated in the prescribed direction by said motive power means, said hook-up unit, while engaged in said descent channel, slides along the shoulders of said rotating worm shaft and thereby descends longitudinally within said descent channel, said rate of longitudinal movement of said hook-up unit thus being indirectly prescribed and governed by said motive power means; and an escapee support means connected to one end of said carrier means, said escape support means to be secured to a potential escapee, whereby as said hook-up unit descends in said descent channel, said escapee support means descends toward the bottom of said descent channel.
