Abstract
This invention relates to a rapid emergency escape system from elevated structures such as the fire-escape system from the top of a sky scraper to the ground level, which rapid descending system includes a vertical wire rope securely anchored to an over-hanging structure secured to the desired level of the elevated structure wherein said wire rope branches to at least two wire ropes with the lower ends of each reaching down to the ground level. The lower end of each of the branching wire ropes includes a connecting means and is connected to the free end of each of the horizontal wire ropes wherein each of the horizontal wire ropes is reeled up into two reels immovably secured and widely separated from each other. The reels include braking means for releasing the horizontal wire ropes while maintaining a certain level of the controlled tension on the wire ropes and means for rewinding the wire ropes back into the reels. The person escaping from the elevated structure to the ground level wears a harness secured around one's torso and limbs which includes a sturdy tether with a strong clasp attached to the free end of the tether. Upon hooking said clasp onto the vertical wire rope with the branching wire ropes stretched tight into the shape of a pyramid as the horizontal wire ropes are reeled up by the reels, the person wearing the harness jumps down, descends, and lands on the ground safely as the tension on the branching wire ropes and the controlled release of the horizontal wire ropes slows down the descending velocity to a safe point as the person approaches the ground level.
