  • Patent number: 4109760
    Abstract: A device for emergency escape from an elevated position in a structure is disclosed which includes an elongated frame fixable at the bottom, either to the structure or adjacent to the structure. The elongated frame is removably fixable to the structure at the top near the elevated position. An elongated collapsible-extensible slide is affixed to the top of the elongated frame and is itself fixable to the structure by removable means so that release of the frame at the top extends the slide from near the elevated position on the structure into a useable form for escape. Escape is accomplished by an individual sliding down the extended slide.
