ABSTRACT:
A foldable polyhedral structure is provided having a plurality of identical diamond-shaped polygons. A first set of diamond-shaped polygons radiates outwardly and downwardly from the top center of the structure and a second set of diamond-shaped polygons extends upwardly from ground level. The design of the polygonal faces is such that the structure folds into a flat compressed structure. A plurality of poles which extend along the edges of each diamond-shaped face will fold together with the structure. The structure may be used as a tent, a hat or as a supporting structure for solar collectors.
