Abstract: The collapsible shelter structure comprises a series of panels held in angularly spaced relationship to define a shelter structure. The framework of each panel comprises a pair of generally parallel bars held in spaced relationship by a single central strut. Corresponding ends of the bars are tied together by flexible means, such as a sheet of fabric, preventing the bars from moving out of parallel. The fabric is slightly stretched by the strut. Conveniently, a single bar is common to adjacent panels similarly formed. In order to determine the angularity of adjacent panels, each intermediate bar is provided with a link piloted on the central portion of the bar, the link having two angularly spaced rigid plugs, one detachably telescoped into the brace of one panel and the other detachably telescoped into the brace of the adjacent panel. A solid, but readily erected and collapsed shelter structure results.

Abstract: The collapsible shelter structure comprises a pair of composite frame sections corresponding, generally, to front and back walls of the shelter. The front and back frame sections are held in spaced relationship by struts that themselves may be foldable as by a retractable splint structure. The struts are external of the fabric or other flexible walls forming the shelter and all of the frame elements remain connected to the companion elements when the structure is collapsed. In a tent configuration, the front and rear frame sections each include rafters that pivotally connect together to form a weather stable arrangement even absent a ridge pole.
