ABSTRACT:
A portable collapsible frame structure for tents, shelters, temporary buildings and the like is disclosed. The frame includes a plurality of elongate, rigid frame members connected by pivotable joints to each other in end-to-end relation such that alternating joints are articulatable in opposite directions to permit folding of the frame members into side-by-side, parallel relation for ease of transportation. The frame structure is held in its erected position by tensile elements which are arranged to apply a compressive force to the abutting ends of the frame members and thereby rigidify the joints of the frame structure.
