<p>Collapsible ladder assembly comprising a ladder storage container having, in closed condition, a fixed upright rear wall, an upright front wall and bottom and top walls joining the front and rear walls, a collapsible ladder being held within the container with its top end secured to the container rear wall. The top wall is made up of a rearward section solid with the rear wall and a frontward section projecting from the front wall, a mechanism releasably locking the top wall sections together. The bottom wall is hinged to the rear wall and to the front wall while the latter is also hinged to the frontward section of the top wall, the hinges allowing the walls to pivot about horizontal parallel axes when the locking mechanism is actuated to release the top wall sections from one another, allowing the container unretained walls and the ladder to unfold downwardly under gravity action.</p> |
