Scaffold structure

A scaffold structure comprising at least two rigid leg frames, each set of leg frames including a pair of spaced-apart legs and a top portion, upper collar elements each having an opening therethrough and being secured to said top portion with said openings extending vertically, a platform frame including a pair of parallel spaced-apart post members having cross-sections complementary to said collar openings whereby said posts are slidably, vertically received through said upper collars, respectively, a platform support including a pair of telescopically engaged platform members fixedly secured adjacent their distal ends to respective ones of the upper ends of said post members, post locking means for locking said posts in selected vertically displaced positions to said collar members with said platform members extending laterally between said leg frames in a plane generally perpendicular to the plane including said legs, support locking means for locking said support members in selected telescopically extended positions, a storage collar element fixedly secured to each of said leg frames, each said storage collar element having an opening therethrough, said openings having an axis disposed generally parallel to a plane including said legs, said storage collar openings being dimensioned to slidably receive said posts therethrough, the outer one of said platform members being open at both ends thereof, the inner one of said platform members being slidably receivable into either end thereof, whereby said leg frames can be vertically stacked in interlocking relationship upon one another, said platform support can be assembled with said posts in closely spaced-apart relationship with said posts being slidably received in said storage collar elements.
