Abstract
Abstract A staging system including curtains, for use particularly around a portable stage unit, which includes movable support towers. A base on each tower is arranged to interlock with an adjacent base for convenience in transporting and compact storage. Horizontal trusses are provided to intergage endwise and be supported on and between support towers. For operative use the trusses are supported on the top elements of the towers. For storage, trusses or tubular supports are mounted on side support elements of the adjacent towers. The trusses or tubular supports have rails or slots, respectively, for supporting stationary and movable curtains to enclose a stage unit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
A staging curtain support assembly which includes a plurality of portable towers, each tower comprising: (a) a base frame having side edges, (b) a vertical support column mounted on said base frame, and (c) means on side edges of said base to intergage and interlock with adjacent base frames to permit said interlocked frames to be moved together as a unit for transport and storage, (d) said base frame being formed of a pipe shaped in a square and said means comprises a gap in said pipe on one edge of said square, and a short pipe section on another edge of an adjacent frame dimensioned to fit within said gap, and interlock means on said short pipe section to move into open ends of said pipe on each side of said gap to lock the adjacent frames together.
Claim 2
Dependent Claim
139 words
A staging curtain support assembly which includes a plurality of portable towers, each tower comprising: (a) a base frame having side edges, (b) a vertical support column mounted on said base frame, and (c) means on side edges of said base to intergage and interlock with adjacent base frames to permit said interlocked frames to be moved together as a unit for transport and storage, (d) said base frame being formed of a pipe shaped in a square and said means comprises a gap in said pipe on one edge of said square, and a short pipe section on another edge of an adjacent frame dimensioned to fit within said gap, and interlock means on said short pipe section to move into open ends of said pipe on each side of said gap to lock the adjacent frames together.
Claim 3
Dependent Claim
93 words
A staging curtain support assembly as defined in claim 1 in which saddle brackets are mounted atop each vertical support column, and at least one composite cross beam is shaped to rest in said saddle brackets of spaced support columns, said cross beam being formed as a truss with a plurality of parallel tubular horizontal runs connected by cross struts, and in which multiple trusses are aligned and each said truss has opposed ends with telescoping projections on one end and recesses at an opposite end to receive projections from an aligned truss.
Claim 4
Dependent Claim
110 words
A staging curtain support assembly as defined in claim 1 in which saddle brackets are mounted atop each vertical support column to support cross beams to rest in said saddle brackets, each said cross beam being formed as a truss with a plurality of tubular horizontal runs connected by cross struts, and in which multiple trusses may be disposed at an angle to each other, projections on at least one end of a truss, and hooks to mount on said projections at one end of a first truss to engage and receive support from a tubular horizontal run of a second truss disposed at an angle to said first truss.
Claim 5
Dependent Claim
40 words
A staging curtain support assembly as defined in claim 1 in which include a cross beam comprising a plurality of extruded sections hinged together to provide an extended beam, said sections having a longitudinally running slot to receive curtain slides.
Claim 6
Dependent Claim
31 words
A staging curtain support assembly as defined in claim 4 in which said extruded section is rectangular in crosssection and said slot is formed in the bottom side of said rectangle.
