Abstract

A portable and foldable platform stage assembly has two support panels movable from a collapsed position with panels closely adjacent each other to an operative position with the panels in a single plane, the inner edges in substantial contact. Roller wheels move from a storage position when the panels are in operative position to a floor contacting position when the panels are collapsed for storage or movement. Outer legs move from a storage position to a vertical operative position when the panels are shifted to operative position. A central support frame pivotally supports the inner edges of the platform panels in the two positions with shaped spaced support links which provide positive support in the operative position and adapt to a receiving position when the panels are moved to storage positions.

Dependent claims

A fold and roll platform assembly comprising:

(a) a pair of platform panels,
(b) outer legs on each said panels to support the outer edges in operative position,
(c) a central support frame to support the panels in storage position when said panels are disposed parallel to each other or in operative position when positioned inner edge to inner edge in a common plane, said support frame comprising:
(1) a base member on said frame extending in the same direction and spaced from said common plane,
(2) main support legs at each end of said frame extending upwardly and pivotally connected to said respective panels adjacent the respective inner edges of said panels, and pivotally connected to said base member,
(3) secondary support legs spaced from said main support legs each pivotally connected to said respective panels and said base member,
said main and secondary support legs being simultaneously movable to allow said panels to shift from a vertical upright storage position to a horizontal operative position, said main and secondary support legs acting in substantially parallel position to support the inner edges of said panels on said base member of said frame.
