Abstract
A frame of flexible hoops sets up automatically through spring tension. The frame has a first hoop and a second hoop attached to the first hoop at equally spaced apart quadrant points. The hoops can flex and twist relative to each other at the quadrant points, but cannot translate away from each other. Tension members hold the erected frame into an oblong shape. Fabric or elastic panels can form the floor, roof and sides, of a tent. The frame may be collapsed to a compact size by folding it into a series of spiralling hoops, against the spring force of the frame.
