Abstract: A mobile canopy system providing shelter from the sun, rain, and wind. The canopy system contains at least two canopy system sections, each containing one centrally located support structure. A truss system is attached to the support structure, perpendicularly extending the length of the canopy system section. Canopy framing systems are perpendicularly connected to, and intervally spaced along, the truss system.

Abstract: A knockdown portable shelter includes two spaced supports each formed of elongated members that can be separated from each other at couplings securing the elongated members to each other. The elongate members include leg portions and a roof portion. A sheet like covering material extends between the roof portion of the spaced supports and at least parts of the leg portions. The covering material is substantially more pliable along the direction extending between the two spaced supports than along a perpendicular direction. Hinges allow folding of the material along lines extending between corresponding couplings. Disconnection of elongate members at the couplings allows the covering material to be folded along the hinges and rolled up along the direction extending between the supports. One example of a suitable covering material is single face corrugated hollow core material. The elongate members are preferably hollow plastic tubes and the couplings are hollow plastic elbows made of PVC.

Abstract: A tent is fabricated from a seamless spherical shell. The floor of the tent is established as a plane interiorly dividing the shell into two chambers. The floor peripherally contacts the inner surface of the shell, and is sealed against the inner surface of the spherical shell. The larger chamber serves as the living chamber, while a smaller air tight chamber is formed between the floor and the shell. The air tight chamber is provided with a valve communicating with the outside environment. When the tent is disassembled, and with the valve opened, the spherical shell will completely deflate and collapse. During erection of the tent, the air chamber valve remains open, and the shell's cap over the floor is manually pulled out away from the tent floor causing a vacuum to form in the smaller airtight chamber. Air immediately flows through the valve filling the air chamber, and by closure of this valve the air is trapped. The air cushions the floor to provide a self inflated air mattress.

Each yoke connector also has a flange extending between tubular members, with an eye in the flange. The fabric enclosure hangs tautly from the frame through the use of one or more loops, one or more pole sleeves, and connectors releasably engageable with the eyes in the flanges attached to the yoke connectors.

Abstract: A retractable dual solar screen which is supported by adjustable poles above the tanner or sun bather and selectively screens out harmful UV radiation and/or provides shade without UV screening. The first screen filters UV radiation and the second screen filters a broad spectrum of sunlight.

The coil spring is sufficiently flexible so that the coil spring can be folded to allow the first and second pole sections to be in side-by-side relationship.

Abstract: A multi-season, reversible tent adapted to accommodate prevailing solar conditions. Selected walls are constructed to include insulated liners and solar reflective and absorptive surfaces which cooperate with a longitudinal access opening. The walls assemble to an irregular triangular shape and can be reversed to optimally collect and reflect solar and thermal radiation in relation to one or more occupants and the prevailing conditions.

Multi-section, shock corded, end support frames are permanently contained at hemmed edges of the end walls. Adjoining pole ends are hinged to one another and longitudinal poles extend between eyelets at the hinge joints. Removeable cover, screen and window panels are supported to the door periphery. Rotating vents with overlapping apertures control interior temperature.
