This invention relates to an improved foldable wall-supporting subframe for fabric-covered collapsible tent walls and the like of the type forming the subject matter of my U.S. Pat. No. 3,810,482, such improvement consisting of attaching the strut sections of each jointed pair thereof to the connector in slightly overlapped transversely-spaced side-by-side relation so as to maximize the spacing between each axis of pivotal movement and the associated stop-forming abutment carried by said connector while, at the same time, minimizing the size of the latter. The invention also encompasses the collapsible tent structure which comprises a pair of the improved subframes hingedly interconnected at their adjacent corners cooperating with one another in fully unfolded condition and with the floor of the cover linking them together to define a free-standing assembly. The invention further encompasses certain of the unique connections by means of which the frame and fabric covering therefor are detachably interconnected to form a self-contained unitary tent structure.
