ABSTRACT:
A fire escape chute for a home includes a housing secured to a building wall below a window having a first chamber for a compressed air tank having an outlet with a normally closed release valve and a second storage chamber. A yieldable chute support pan forms the bottom of the second chamber and is pivotally mounted upon the housing and retained in a horizontal position. A hollow double wall open ended collapsible chute is stacked within the second chamber upon the pan. A normally closed cover is pivotally mounted upon the housing and supportably retains the pan. A retracted expansion device within the second chamber is connected to the cover and when manually released tilts the cover to an upright position retainingly engaged by a latch. An air plenum on the cover having a plurality of outlets is connected to the air release valve. One end of the chute encloses and is secured to the plenum and communicates with its outlets. The cover outwardly opens upon release of the expansion device, triggers the air supply to the plenum and chute, the pan drops and the chute drops from its housing to instantly inflate.
