Folding, collapsible ladder assembly

摘要

A collapsible, foldable ladder of use as an emergency escape means such as a fire escape ladder, has a plurality of channel section rungs extending from side to side across the width of the ladder, and side support means extending between adjacent rungs at ends thereof. The side support means each comprise two pivotally connected, rigid sections, pivotally connected to the ends of upper and lower rungs. The ladder can be collapsed, whereupon the side support members fold inwardly and fit within the channel sections of the rungs, so that the rungs rest upon top of one another, and extended e.g. under its own weight when suspended by one end, whereupon the side support members are extended perpendicularly to the transverse extent of the rungs.
