An escape chute made up of a framework which can be horizontally projected outward from a building; a double tubular body having an inner cylinder and an outer cylinder made of cloth, and a spiral slide cloth forming a slide surface which is fixed between the inner cylinder and the outer cylinder; an upper entrance at the top and an exit at the bottom; one or more intermediate access apertures and intermediate entrance passages made of cloth to permit entrance into the space between the inner cylinder and the outer cylinder wherein the height of the lower edge of the intermediate access aperture is higher than the spiral slide surface at the position so as to prevent a part of a person from becoming hung up upon the aperture. The intermediate entrance passages are held by ropes connected to the framework. One or more intermediate exits are formed on the side surface of the bottom outer cylinder at higher than the exit.

Escape chute

A fire escape comprises an escape device, a hardware which is expandable or foldable and hangs the escape device therefrom, a storage container for storing or accommodating the escape device and the hardware, and a brace frame which has the hardware provided in the storage container so as to be movable vertically from the inside of the storage container. With raising of the brace frame, a part of the escape device is thrown out and down from the storage container. The falling force of the escape device partly thrown out is used to pull out the remaining escape device and to deploy the hardware.
