Abstract (en)
[origin: WO0008292A1] A collapsible escape ladder (1) having rungs (5) of a relatively strong and thin material with integral stand-off projections (6) that allow the escape ladder to be safely descended and of a cross section that allows the escape ladder rungs to nest to a high degree of compactness. The escape ladder is readily deployed by means of a cover (16) having two sets of temporary fasteners. In an emergency, the escape ladder is deployed by partially unwrapping the cover (16) to a first state which allows an attaching member (2) to be removed and placed over a window sill. After insuring that narrow fabric supports (4), which attach the attaching member to the rungs, are not twisted between the attaching member and a top rung of the escape ladder, the multiple rungs (still wrapped by the cover and secured by a second set of temporary fasteners) are supported using a handle (17) attached to the cover. The handle is then held outside the window and dropped. The momentum of the falling package of rungs is sufficient to open the second set of temporary fasteners and thereby reliably deploy the escape ladder in its proper orientation. Also disclosed is a mounting plate, which may optionally be used to stabilize the attaching member (2) to a wall surface beneath a window sill and to ensure that the attaching member (2) will attach securely over any window sill, regardless of the thickness of the wall.
