Abstract
A fire ladder includes as opposite sides a pair of elongate flexible cables in the form of interwoven strands of wire. Hollow tubes flattened and scored on their upper surfaces extend rigidly between the cables to provide the ladder rungs. The rungs have initially open ends into which looped portions of the cables are inserted. One side wall of the rung is then crimped inwardly and pressed against the opposite wall to firmly clamp the cable within the rung. Hook-like arms secured to the ends of the cables serve to suspend the ladder from a window sill and may be folded by means of a hinge structure to a collapsed storage position occupying little space. A spring located within the hinge arms maintains the hook-like support arms spaced apart during use, while stops prevent the arms from pivoting excessively.
