ROLL-FORMED FRAME FOR PORTABLE ENCLOSURES ABSTRACT OF THE DISCLOSURE A roll-formed frame is provided for portable enclosures of the type comprising a series of screened wall panels with flexible hinges interconnecting the upright edges of the same. The wall panels are arranged into a closed polygon configuration, and support a domed, fabric roof. A pair of flexible cables extend around the top and bottom of the wall panels with retainers interconnecting the same, and retain the wall panels and roof in position. Roll-formed frame segments are interconnected to form the rectangular margin of the wall panels, and include a roll- formed channel in the outer peripheral edge. The channel has a dovetailed shape to interchangeably receive and retain therein a bead portion of the hinge, the fastener cables, and a body portion of the retainers. Preferably, the beads on the flexible hinge have a wedge shape which fits loosely into the side channels, and the cable retainers are sym- metrical, so that they can be used on either end of the wall panels.
