PCT No. PCT/AU96/00329 Sec. 371 Date Jan. 22, 1998 Sec. 102(e) Date Jan. 22, 1998 PCT Filed Jun. 3, 1996 PCT Pub. No. WO96/41928 PCT Pub. Date Dec. 27, 1996A collapsible support structure for a covering. The support structure includes, at least, three apex poles with first ends pivotally connected together, so that, in use, the poles are able to be moved between a raised configuration, in which second opposite ends extend outwardly in different directions to create a pyramid-shaped frame and a collapsed configuration. The support structure also includes pairs of perimeter poles, with each pair forming an inverted "V" between the opposite ends of adjacent apex poles, when in the raised configuration, and a bracket device including struts, which extend between, and are pivotally attached to, respective apex poles intermediate their ends, along with a central flange element, in which the first connected ends of the apex poles and the central flange element may be pushed toward each other to obtain the raised configuration or pushed apart to obtain the collapsed configuration. The apex poles and the perimeter poles are pivotally connected so as to fold together into close, substantially parallel, positions when in the collapsed configuration. The covering is, preferably, attached to the support structure by a hook-and-loop attachment and the connected perimeter and apex poles are secured in an open position by a releasably operated telescopic brace device pivotally connected therebetween. |
