ABSTRACT:
A portable and collapsible platform (10) designed to be hung to a set of attachment hooks (30) that are attached to a stationary structure such as a wall, beam or building eaves. The platform (10) includes a pair of inward vertical members (12), and a pair of outward vertical members (14) that are rotatably connected by a plurality of horizontal members (16) and a pair of angular support members (18). On top of the horizontal member pairs is placed a utility platform (20) that allows a worker to stand or sit. The collapsible feature of the invention is easily performed by pressing inwardly against the outward vertical members (14) until all the outward members (14), (16), (18)are nested within the inward vertical members (12). Once collapsed, the inward and outward vertical members (12), (14) are locked in place by a locking means. The platform (10) can also function as a multiple shelf by placing a platform (20) on each horizontal member pair or ladder rungs ( 20) may be inserted through the outward vertical members to allow the platform to function as a ladder.
