ABSTRACT:
An extendible ladder includes a sealed housing for housing the ladder in a collapsed condition. The ladder mounts to a support wall such as the side of a home or an apartment building. The ladder is extendible during an emergency by opening the sealed housing which allows gravity to extend the ladder. Rollers are included with the ladder to prevent the support wall from interfering with the ladder as the ladder is extended. The housing may take the shape of an awning for mounting over a window in the support wall.
