An elevationally adjustable folding stage (100) has a frame (102) which folds along a center of the stage (100) from a storage position to a use position. Stage panels (104, 106) of interchangeable widths form a stage surface and are reversible and interchangeable. The stage (100) may also support additional panels between stages (100) extending therefrom to form an extended stage surface. The stage (100) has a roller assembly (118) which lifts the stage (100) up so that rollers (120) engage the floor for rolling between storage and use locations. Connectors (135) between the frame (102) and the stage (104, 106) offer quick connection without additional pieces. Connectors (135) also provide for inserting risers to raise the height of one panel (104, 106) of the stage (100) relative to the other. In addition to the risers, multipanel supporting bases may be used to support the panels extending from the edges of the stage between stages. The panels between the stages may be stored on the stage (100) while in the use or folded position by hook members (172, 174) which rotate from a storage to a use position to retain the additional panels. Folding of the stage (100) is assisted by a spring folding assist member which prevents closing of the stage (100) and assists in the initial opening of the stage (100) toward the folded position. Accidental folding of the stage (100) is also prevented by a locking linkage (155) and a spacing linkage (192) which lock the stage (100) in the use position to prevent accidental folding and also to maintain the stage (100) in the use position when elevationally adjusting the stage panels (104, 106). |
