ABSTRACT:
The present invention is a fast-erecting tent in which several open-ended arcuate interconnect via a single connector. The frame of the tent includes 1) a pair of resilient, planar open-end arcuate sections that form a filiform base loop; 2) a pair of resilent open-end arcuate sections that form a filiform upper loop; 3) a connector which links a terminal end of the first arcuate section of the base loop plus a terminal end of the first arcuate section of the upper loop to the terminal end of the second arcuate section of the base loop plus the terminal end of the second arcuate section of the upper loop; and 4) a segmented, internally biased, arch shaped tubular strut. The ends of the strut are slidably and rotatably connected to the arcuate sections of the base loop. The strut is connected to the arcuate sections of the upper loop by means of a twist clip. The fabric covering is wrapped around and attached to the frame by conventional means. The connector is a sleeve with a through-bore. Through-bar having a cross-section of multiple, parallel, partial, interconnected, right circular cylinders and is designed so that the terminal ends of the arcuate sections forming the filiforms loops can be retained in the through-bore mainly by friction. The terminal ends of the arcuate sections that form the filiform loops are permanently fixed within the through-bore at a first end of the connector but are free to slide, rotate, and swivel in and be detached from a second end of the through-bore. Both the base loop and upper loop can be either elliptical or semi-elliptical.
