ABSTRACT:
A self storing fire escape ladder of foldable type, including a plurality of pivotally interconnected rung sections and enlarged hook means for engaging a window sill or similar structure during use. The hook means is of effective width less than that of the rung sections, and so contoured that when the rung sections are folded against each other to form a compact unit, the hook means may at least partially encircle the rung sections to hold them in mutually folded relation and form carrying handle means. Optional latching means is provided to prevent movement of the hook means relative to the compact unit when the former is employed as a carrying handle.
