ABSTRACT:
A novel escape system comprised of a plurality of escape devices each which resemble a window shutter, are mounted on the outside of a building, adjacent the windows vertically above the next lower escape device. Since these take up no space inside of the building, and are aesthetically pleasing, they are less likely to be removed or overridden making them functional a greater percentage of the time. Each is comprised of a frame to hold a plurality of slats connected to a collapsible vertical connecting means a predetermined distance apart from the others. In its storage position, the slats are held in the frame in an angled position resembling louvers. When in the operational position, the slats are allowed to drop down out of the frame and extend down to the next lower escape device with the slats acting as steps of a ladder. The bottommost end of the escape device connects to the top of the next lower escape device to create a continuous escape system allowing egress from any floor to the ground.
