发明名称 Fold and roll staging.
摘要 <p>A portable and foldable platform stage assembly has two support panels (20)(22) movable from a collapsed position with panels (20)(22) closely adjacent each other to an operative position with the panels (20)(22) in a single plane, the inner edges in substantial contact. Roller wheels (64) move from a storage position when the panels (20)(22) are in operative position to a floor contacting position when the panels (20)(22) are collapsed for storage or movement. Outer legs (30) move from a storage position to a vertical operative position when the panels (20)(22) are shifted to operative position. A central support frame pivotally supports the inner edges of the platform panels (20)(22) in the two positions with shaped spaced support links (72)(44) which provide positive support in the operative position and adapt to a receiving position when the panels (20)(22) are moved to storage positions.</p>
