  • Collapsible ladder having highly nesting rungs with integral stand-off projections

    Issued US 6334510

    A collapsible ladder having rungs of a relatively strong and thin material with integral stand-off projections that allow the ladder to be safely descended and of a cross-section that allows the ladder rungs to nest to a high degree of compactness. The ladder is readily deployed by means of a cover having two sets of temporary fasteners. In an emergency, the ladder is deployed by partially unwrapping the cover to a first state which allows an attaching member to be removed and placed over a…

    A collapsible ladder having rungs of a relatively strong and thin material with integral stand-off projections that allow the ladder to be safely descended and of a cross-section that allows the ladder rungs to nest to a high degree of compactness. The ladder is readily deployed by means of a cover having two sets of temporary fasteners. In an emergency, the ladder is deployed by partially unwrapping the cover to a first state which allows an attaching member to be removed and placed over a window sill. After insuring that narrow fabric supports, which attach the attaching member to the rungs, are not twisted between the attaching member and a top rung of the ladder, the multiple rungs (still wrapped by the cover and secured by a second set of temporary fasteners) are supported using a handle 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 reliable deploy the ladder in its proper orientation. Also disclosed is an attaching plate, which may optionally be used to stabilize the attaching member to a wall surface beneath a window sill and to ensure that the attaching member will attach securely over any window sill, regardless of the thickness of the wall
