  • Patent number: 5226440
    Abstract: Readily assemblable and disassemblable tent, awning and canopy frame structures incorporating conventional slip fit junction elements and beams and rafters of double tube form which enable greater spans between uprights and simplified structures for larger area tent or like frames, the configuration of the double tube beams and rafters being such that the double tube beam, rafter and upright components can be interchanged with single tube beams, rafters and uprights. The unique double tube forms are characterized by a cross-sectional configuration including two circular walls interjoined by two planar walls interconnected with the circular walls substantially at diametrically opposed circumferential locations in the circular walls and by increased strength-to-weight ratios.
