Abstract:

A support structure for mounting and rollably supporting stage backdrop panels and the like is disclosed. A base frame includes a plurality of caster mounting members, with each mounting member rotatable relative to the base frame about an individual mounting member axis. A plurality of casters are rotatably carried by each mounting member, each caster being offset from the axis of its respective mounting member. Several of the mounting members can be attached to the base frame by telescoping fittings, allowing the height of the base frame to be adjusted without disengaging the casters from rollable engagement with the stage floor.
