  • Patent number: 5701703
    Abstract: An elevationally adjustable folding stage has a frame which folds from a storage position to use position. Stage panels form a stage surface and are reversibly and interchangeably mounted. Connectors insert into passages from the stage frame through the stage panels and provide quick connection without additional connector elements. The connectors rotate within the channel and compress an annular sleeve member axially, forcing the sleeve outward to engage the sides of the passage and secure the stage panel to the stage. The connectors are at or below the upper stage surface and are accessible axially from above by an actuator tool.

  • Patent number: 5349789
    Abstract: An elevationally adjustable folding stage has a frame which folds along a center of the stage from a storage position to a use position. Stage panels of interchangeable widths form a stage surface and are reversible and interchangeable. The stage may also support additional panels between stages extending therefrom to form an extended stage surface. The stage has a roller assembly which lifts the stage up so that rollers engage the floor for rolling between storage and use locations. Connectors between the frame and the stage offer quick connection without additional pieces. Connectors also provide for inserting risers to raise the height of one panel of the stage relative to the other. In addition to the risers, multi-panel 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 while in the use or folded position by hook members which rotate from a storage to a use position to retain the additional panels.
