Claims (4)

1. An escape system for positioning between the floor of one story of a building and the ceiling of a story below the firstmentioned story, said system comprising: an escape means including a first frame means adapted to be positioned in a hole in the floor of the one story and a second frame means adapted to be positioned at the other end of said hole in the ceiling of the story below said firstmentioned story, an adjustable bellows type shell means extending between said first and said second frame means forming an escape passage for an evacuee, a cover member positioned over at least one of said frames for closing the hole when the system is not in use, and an escape unit secured adjacent said escape means and adapted to extend through at least part of said shell means when said cover member is open for use by the evacuee in passing through said escape means.
2. An escape system as claimed in claim 1 in which said shell means has a coating of a heat resistive material on the exterior thereof.
3. An escape system as claimed in claim 1 in which said shell means has a coating of an elastic buffer material on the interior surface thereof.
4. An escape system for use in a multi-story building comprising a plurality of escape means adapted to be positioned between the floor and ceiling of each of at least the majority of said stories, each of said escape means including a first frame means adapted to be positioned in a hole in the floor of one story and a second frame means adapted to be positioned at the other end of said hole in the ceiling of the story below said first-mentioned story, an adjustable bellows type shell means extending between said first and said second frame means forming an escape passage for an evacuee, a cover member positioned over at least one of said frames for closing the hole when the system is not in use, and an escape unit secured adjacent said escape means and adapted to extend through at least part of said shell means when said cover member is open for use by the evacuee in passing through said escape means.
