A tenting structure with two angularly related sidewalls forming a roof and having at least one collapsible frame for externally supporting each of the sidewalls and where the frame includes a hub radially carrying a plurality of flexible struts whose distal ends are secured in external pockets positioned around the edges of each of the sidewalls and where the frame is sized and dimensioned in respect to the sidewalls that the frame members take on a compression induced dish shaped outward bow. The hub includes a plurality of pivotal strut mounting sockets which rotate about their pivotal axis to a discrete splayed position and to a definitive stowed position.

In a tenting structure: a sidewall and roof assembly comprising a pair of inclined pliant erectile skin members each having external and internal surfaces and at least one common straight edge; means interconnecting the skin members along their common straight edges wherein the erected skin members are adapted to be positioned so that the line defining their interconnection describes the vertex of the angle formed by the planes of the inclined skin members; at least one frame means for supporting the skin members, each of which frame means includes; a plurality of flexible struts; and hub means carrying the proximal ends of the struts, including a plurality of pivotal sockets carried by the hub to receive the proximal ends of the struts; releasable stop means engaging the said sockets to arrest the movement thereof at the extremes of approximately 100°of rotation about the pivotal axis of the sockets; a base member having a plurality of cavities, each having opposing side chambers defining bearing means at the forward end thereof; journal means integral with the pivotal sockets and disposed for rotation in the bearing means; and curvilinearly faced seats, one each disposed in the bottom of each cavity and engaging the pivotal sockets on the side thereof opposite the surface thereof engaging the bearing means; a plurality of pocket means integral with the skin members and disposed along the perimeter of the surface thereof to receive the distal ends of the struts, the straightline distance between opposing pocket means being less than the diameter defined by the hub means and a pair of diametrically opposed flexible rods so as to place the said pair of rods in compression, creating an outwardly distended bow in the said rods.
