Abstract
A collapsible ladder comprises two stiles formed of telescopically collapsible sections (10), a plurality of rungs (11) each mounted between two sections of the respective stiles, and latch mechanisms located in the rungs for automatically locking the sections (10) of the stiles relative to one another when the sections are extended. The latch mechanisms in each rung are arranged to release the sections of the stiles connected to the next higher rung when the rung is collapsed against the next lower rung.
