Abstract: The disclosed invention is a collapsible ladder of simple construction and operation that can remain secure whilst being locked in the collapsed position to prevent unauthorised access. The ladder consist of a plurality of rungs pivotally connected to a pair of parallel rails. The key operated locking mechanism is designed to be tamper proof. The locking mechanism includes a rotatable latch that securely engages an opening in one of the rungs.

Abstract: The present invention relates broadly to a collapsible ladder (10) comprising a pair of opposing rails (12A) and (12B) interconnected with a plurality of rails (14A) to (14J). The collapsible ladder (10) can be moved or manipulated from a collapsed condition to an operative condition. In the collapsed condition the opposing pair of rails are (12A/B) locate adjacent or abut one another whereas in the operative position the rails (12A/B) are laterally spaced with the interconnecting rungs (14A) to (14J) being disposed substantially perpendicular thereto. Each of the rungs such as (14A) is at its opposing ends pivotally connected to respective of the opposing pair of rails (12A/B). This pivotal connection between the rungs such as (14A) and rails (12A/B) allows the ladder (10) to move from its operational to collapsed conditions.
