发明名称 READILY DEPLOYABLE PORTABLE ESCAPE LADDER
摘要 A readily deployable, portable escape ladder includes nestable rungs maintained in a releasable, stacked state. The ladder includes a cover having a releasable fastening system which, when released, permits the ladder to move from the stacked state to an extended state. The rungs include integral standoff members to displace the ladder from the surface of a building when deployed. The rungs are spaced one from the other, along a flexible mounting member. The mounting member penetrates the rungs in a staggered orientation.
