<p>A collapsible escape ladder comprising a series of rigid rungs (12) which are joined together at spaced positions along a pair of outer vertical webbing strips (13), the rungs being connected to the strips by a series of spaced rods (16) located within webbing loops (15) in the end regions of the rungs (12). The webbing (13) passes through slots (14) in the end regions of the rungs. The assembly is retained in a folded condition by pivoted arms (18) with extension arms (19), and the arms (18) may be pivoted outwardly for location against the sides of an upper floor window opening to enable the latter to be suspended therefrom. A top member (10) is further retained by an adjustable hook-like member (21) which locates over the inner edge of an interior window sill.</p> |
