Patent number: 6530455Abstract: An escape ladder provides emergency egress from a dwelling and generally comprises a hook assembly connected to a ladder assembly. The hook assembly includes a pair of laterally spaced clamps and the ladder assembly includes a pair of straps attached to the clamps and a series of rungs extending between the straps. Each clamp comprises an upper hook and a lower hook connected via a hinge. The pair of clamps are connected via a collapsible stabilizer bar. The hinges and stabilizer bar permit the clamps of the hook assembly to be folded and compressed to form an un-deployed configuration of the hook assembly. The rungs are of common cross-sectional shape permitting them to be nested in an un-deployed configuration of the ladder assembly. The escape ladder of the present invention provides secure attachment to the dwelling, folds into an un-deployed package that small and compact for storage, yet is assembled to provide user-friendly deployment that can be reliably deployed in a high stress situation.Type: GrantFiled: August 11, 2000Date of Patent: March 11, 2003Assignee: Walter Kidde Portable Equipment, Inc.Inventors: Henry Arnette, Judd W.

Publication number: 20030037991Abstract: 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.Type: ApplicationFiled: August 1, 2002Publication date: February 27, 2003Inventors: Aldo J. Dibelardino, Andrew D. Ive, Ezio C. Dibelardino
