ABSTRACT:
This invention relates to an improved free-standing tent frame having at least three four-sided collapsible subframes linked together in side-by-side relation and angled relative to one another so as to stand alone while leaving a gap between the endmost subframes, and a triangularly-segmented roof frame having one more triangular segment than there are subframes in the wall structure. The invention is also characterized by a hub assembly for the subframes of the wall assembly that comprises a series of three or more strut-receiving socket subassemblies hingedly interconnected to produce a closed polygon in which those having four or more sides are self-adjusting to accommodate various included angles between adjacent struts without the latter having to bow or bend. The invention further encompasses the socket subassemblies which employ the hinge pins at opposite ends of the hinge member as keepers to retain the pivot pin of the socket-receiving element in place while the wedge-actuated fingers of the latter releasably grip the hollow strut end without the need for adhesives or more conventional fasteners.
