ABSTRACT:
A normally retracted escape ladder assembly that includes a framework mountable on a building wall, a plurality of ladder sections movably interconnected and having at least one such section attached to the framework, a platform, and a latch maintaining the ladder sections in a collapsed condition and actuated to release the ladder sections upon application of weight to the platform. The framework includes a wall abutment section and a ladder support section projecting therefrom. The platform is carried by the framework and is pivotally attached to either the wall abutment section or the ladder support section of the framework. Connected to the platform and carried by the framework is a latch which engages at least one of the ladder sections to maintain the ladder sections in a collapsed condition. The application of weight to the platform allows the ladder sections to assume an extended condition. In one embodiment of the invention the plurality of ladder sections in their extended condition lock to form a rigid escape ladder. The use of the latch in cooperation with the platform provides for automatic quick and simple extension of the ladder sections to form an escape ladder.
