Abstract: A peripheral support frame is provided over which to receive and for supporting a flexible canopy or tent cover. The frame includes a plurality of horizontally elongated peripheral frame members with peripherally adjacent frame members including a pair of adjacent ends and an upstanding leg assembly is disposed between and provided for support of each pair of adjacent frame member ends. Each leg assembly includes an upper head from which the adjacent peripheral frame member ends are removably supported against angular displacement relative to the associated leg assembly about axes extending longitudinally of the peripheral frame members with only a single shank-type fastener being secured between each peripheral frame member end and the associated leg assembly subject only to tensional forces.
