Abstract
The subject invention is a device for use as a modular display system for ceiling fixtures and, in particular, electrical fixtures and the like such as lighting fixtures and ceiling fans. The invention includes adjacent horizontal trusses which are adjustably supported in a vertical direction upon upright frames that are erected to span specified aisle dimensions. The horizontal trusses provide a portable overhead ceiling for mounting electrical fixtures and the like which are to be displayed.
Claims15
An overhead display apparatus comprising:
- a plurality of adjacent pairs of opposing support frames, each support frame of said pairs of opposing support frames having a truss support extending vertically therefrom, each said truss support having a plurality of attachment points thereon;
- a plurality of substantially horizontal, vertically adjustable trusses, each of said trusses having a first end and a second end, said first end being coupled to said truss support at one of said plurality of attachment points of one support frame of one of said pairs of opposing support frames and said second end being coupled to said truss support at one of said plurality of attachment points of the other support frame of said pair of opposing support frames, said plurality of trusses thereby being adjacent in accordance with said plurality of adjacent pairs of opposing support frames;
- a plurality of purlins extending between adjacent trusses and attached thereto;
- and
- a plurality of fixture mounting bars extending across said purlins and attached thereto, said fixture mounting bars providing a mounting location for attaching at least one ceiling fixture.
