Abstract: A multipurpose adjustable panel system having support beams continuously adjustable between zero pitch and a pitch exceeding zero, wherein support beam pitch is influenced by vertical adjustment of support post assemblies and by horizontal spacing of support post assemblies. Multiple mounting fixtures are incorporated to accommodate beam pitch adjustment including pivotable beam support fixtures adjustably and positionably secured along the bottoms of the beams and pivotable panel support node fixtures adjustably and positionably secured along the tops of the beams, the pivotable beam support fixtures and the pivotable panel support node fixtures enabling ready adjustment of the pitch of the beams.

Abstract: A portable platform-support system provides an external platform comer for supporting a platform surface structure; the system having a rigid comer-support apparatus having a non-integrating outer-facing portion with opposing outer edges, an inner portion, and a recessed pocket; a channel member having an elongated shape, a slot aligning with the recessed pocket, and an upper surface to provide support to the platform surface structure; and a reinforcement member securely coupled to and extending from the inner portion with the reinforcement member to securely support the channel member.

Abstract: A portable platform-support provides an external platform corner for supporting a platform surface structure. The external platform corner employs a rigid corner-support apparatus that is connectable to other components. The rigid corner-support apparatus includes a non-integrating outer-facing portion with opposing outer edges and an inner portion. A channel member has an elongated shape and an upper surface adapted to provide support to the platform surface structure, and a reinforcement member is securely coupled to and extending from the inner portion with the reinforcement member being adapted to securely support the channel member.

Abstract: One-piece staging support for use in staging which can be horizontally collapsed. Cylindrical pivot supports are supported at a common level about a centrally located cylindrical body for the support of pivoted stage support members.

Abstract: Stage system having lightweight and interchangeable support framework members and components at various levels which support lightweight high strength platform panels of composite construction having a composite wood and high density foam core surrounded by a bottom pan and a top pan. The bottom pan and top pan engage each other as a closed container to completely surround and enclose the composite wood and high density foam core.
