Sky-slide emergency escape system

摘要

This invention relates to a rapid emergency escape system from an elevated structure which could be used as a fire-escape system from different levels of high rise building to its ground level. The sky-slide emergency escape system of the present invention includes a guide wire rope branching to at least two braking wire ropes wherein the upper end of the guide wire rope is secured to an elevated structure and each of the branching wire ropes reaching down to the ground level is reeled on each of a plurality of take-up reels equipped with a braking means for releasing the branching wire ropes under a preset tension and a means for rewinding the branching wire ropes on the reels. These take-up reels with braking means and rewinding means are widely separated from each other and immovably secured at the ground level. The person escaping from the elevated structure to the ground level wears a harness secured around one's torse and limbs which includes a sturdy tether with a strong clasp attached to the free end thereof. Upon hooking said clasp onto the guide wire rope depending from the elevated structure and branching to at least two braking wire ropes, which combination of wire ropes is tautly disposed into the shape of a pyramid because of the tension on the wire ropes generated by the reeling action of the take-up reels, the person wearing the harness jumps down, descends at a high speed following the guide wire rope, slows down as the braking action provided by the branching wire ropes takes place, and lands safely. As soon as the escaped person unhooks the clasp attached to the harness from the branching wire ropes, the take-up reels reel up the branching wire ropes automatically and puts the guide wire and the braking wires again in a taut condition readying itself for next descending person.
