Abstract
An internal, self-supporting, tent suppot framework. The collapsible framework includes a number of side and ridge support poles which mount to radially adjustable pole couplers. The couplers retain the support poles at preferred angular orientations in multiple wall planes as a support skeleton for an overlying fabric cover. Each coupler includes a pair of cast sleeves wherein a body piece includes a longitudinal bore, a projecting wing arm and a pair of hinge arms having transverse bores. A horizontal pole couples the hinge arms together in one plane, as a pair of other poles are supported to the longitudinal bores in a second plane at a splay angle established by the wing arms. The wing arms overlap and are retained with a fastener fitted between the arms.
