Abstract: A compact collapsible camping chair includes upper tubes, leg tubes, a molded central tube connector and a seat back. The tube connector is molded from aluminum, zinc or plastic reinforced with glass fiber. Lower ends of the upper tubes fit snugly into circular upper holes in the central tube connector, and upper ends of the leg tubes fit snugly into circular lower holes in the central tube connector. Upper ends of the upper tubes fit into tube receptacles in the seat back. The two longer upper tubes are bent, whereas the two shorter upper tubes are straight. Elastic cords pass from the upper tubes, through the tube connector and into the leg tubes and tend to pull the tubes into the holes in central tube connector. The upper tubes, leg tubes, central tube connector and seat back can be placed in a bag that is less than one foot long.

Abstract: A collapsible beach chair includes upper tubes, leg tubes, a central tube connector, a seat back and a fabric support base. Lower ends of the upper tubes fit into upper holes in the tube connector, and upper ends of the leg tubes fit into lower holes in the tube connector. Upper ends of the upper tubes fit into first tube receptacles in the seat back, and ground ends of the leg tubes bit into second tube receptacles in the support base. The upper holes are disposed in an upper portion of the tube connector that swivels over a lower portion into which the lower holes are bored. The upper portion and the attached upper tubes swivel about a shaft that passes through the upper and lower portions but does not extend above or below the tube connector. The fabric support base prevents the leg tubes from sinking into the sand.

Abstract: A compact collapsible chair includes upper tubes, leg tubes, a central tube connector and a seat back. The upper tubes are formed from detachable sections. Lower ends of the upper tubes are inserted into upper holes in the central tube connector, and upper ends of the leg tubes are inserted into lower holes in the central tube connector. Upper ends of the upper tubes fit into tube receptacles in the seat back. No part of the upper tubes other than the upper and lower ends contacts any part of the collapsible chair. The upper holes are disposed in an upper portion of the central tube connector that swivels over a lower portion into which the lower holes are bored. The upper portion and the attached upper tubes swivel about a cylinder that passes through the upper and lower portions but does not extend above or below the central tube connector.
