Within the prior art, most of the disclosed telescopically collapsible ladders (see for example U.S. Pat. No. 3,653,463) have stiles of open part. Such a development inevitably makes for a weaker structure and, in the popular embodiment of the invention, the stiles are of a daily closed part, being preferably shaped of round tubing.
The hazard of individuals being trapped on the first ground of a building has lengthy been recognised and varied proposals have been made to supply a collapsible ladder which might be stored easily and which doesn’t help unauthorised entry into the constructing by being completely prolonged.

When the uppermost part of the stiles is collapsed, then as it reaches its lowermost place, it releases the subsequent lower section thereby enabling the ladder to be collapsed from the highest downwards.
According to the present invention, there is supplied a collapsible ladder comprising two stiles fashioned of telescopically collapsible sections, a plurality of rungs every mounted between two sections of the respective stiles, and latch mechanisms located in the rungs for mechanically locking the sections of the stiles relative to 1 one other when the sections are prolonged, wherein the latch mechanisms in each rung are arranged to release the sections of the stiles related to the subsequent greater rung when the rung is collapsed in opposition to the next decrease rung.
