Abstract
Abstract A fire escape device adapted to be mounted to an external wall of a building below a window. A platform is pivotally mounted on a wall. The chain or wire ladder is connected to the platform. When the platform is folded up, it provides an enclosure for the folded ladder. When the enclosure is opened, the platform falls pivotally to a horizontal position. The platform has a trap door in it, operating on hinges that also allow it to pivot downward and release the ladder inside. The ladder descends to the ground.
