ABSTRACT:
A safety escape chute for assisting in rescue of persons from burning buildings and the like has a generally U-shaped chute mounted on a vehicle and having a length to reach from the ground to the highest level required. The system includes extensible supports which may be hydraulically operated to extend the upper end of the chute adjacent a window from which persons are to be evacuated. The chute includes a water inlet at the upper end and a drain manifold partway down the chute. Water is pumped out the water inlet so as to form a thin flow of water down the center of the chute which is collected at the drain and returned to the source. This water flow will accelerate persons entering the chute. The vertical side portions of the chute adjacent the water flow are lined with an anti-friction material such that the person may utilize this material to control his rate of descent. Below the drain, the remainder of the chute is covered with anti-friction material to decelerate the person so that he may alight safely on the ground. The system is preferably mounted to a turntable on the vehicle so that it may be rotated to the most advantageous angle for approach to a building.
