Abstract
Abstract A portable tent-like shelter comprises an open frame made of tubular elements which slip fit together to form a roof portion. The frame has four elongated legs extending downwardly from the corners to cause the frame to be free-standing. A fabric cover is placed over the roof portion of the frame and the cover has boxed ends and sides which extend downwardly from the roof portion of the open frame. Elongated, narrow, fabric leg panels are attached to the fabric cover at each of its corners and extend downwardly along the legs of the frame. The leg panels are releasably attached to the legs at the lower ends to place tension through the leg panels to the cover to hold it in place on the frame.
