ABSTRACT:
An escape ladder for side rails with multilevel dwellings comprising a pair of side rails inverted "J" hooks which are pivotal outward to engage a window sill and inward to fold. The side rails extend downward sufficiently to support two or three more steps. Extendable below the rigid portion of the ladder are a second set of steps supported by a flexible support means such as rope with intermediate spacers between steps. Upon applying pressure to the upper one of the second set of steps, the lower portion of the ladder is rigidified. The ladder, after use, may be folded and stored in a bag with the hooks used as handles.
