Abstract: 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 symmetrical, so that they can be used on either end of the wall panels.

Abstract: A seating unit that includes two side support assemblies and a plurality of lateral connecting rods which are received in mounting apertures through the side assemblies. A securing clip is received inside the hollow ends of each lateral connecting rod to prevent the side assemblies from separating. Each clip has a pair of extending legs with a locking tab that seats in a recess within the lateral rod. The lateral rods flex under the weight of a person seated on the seating unit in order to create a frictional locking force between the lateral rods and side assemblies to prevent the side assemblies from sliding toward each other.

Abstract: A patio enclosure adapted for affixation to the exterior wall of an existing structure consisting of a plurality of side and front panels, a roof support structure and an overlying fabric roof. The roof support structure includes a series of rafters having centrally depending therefrom a cable receiving slotted finger. A cable extends between the rafter assembly from its point of affixation to the existing structure to its point of affixation to the front panels of the enclosure. The cable passes through the slot in the depending finger.

Abstract: A portable enclosure having a series of panels hingedly affixed together to form a closed polygon. A flexible linking member and a vinyl hinge or sealing strip fixed between adjacent pairs of panels interconnect the panels such that the enclosure can be folded. The pivot link at the upper and lower portions of the panels are basically identical and provide means for securing and retaining a roof structure at the top while the link located at the bottom provides a convenient means for fixing the enclosure to the ground.

Abstract: A support structure for a flexible cover such as is utilized on a portable enclosure wherein the tip of the supporting ribs or tubes engages the cover to maintain the same in position. The tip which is disclosed in this specification includes a shank section which is telescopically received by the tubular rib and a retaining section passable through a grommet in the cover. The tube is provided with a plurality of apertures and a resilient detent, forming a part of the tip, passes selectively thereinto to restrain telescopic movement of the tip with respect to the tube. The effective length of the rib can be altered by selectively positioning the detent in one of the apertures.
