A rigid, multipurpose, polyhedric structure which may be folded away on its own base has a base, a roof, vertical lateral surfaces (3), (4) and (5) provided with grooved fold lines extending along the diagonal of each lateral surface, and a side surface free on at least three sides, connected togeth
A rigid, multipurpose, polyhedric structure which may be folded away on its own base has a base, a roof, vertical lateral surfaces (3), (4) and (5) provided with grooved fold lines extending along the diagonal of each lateral surface, and a side surface free on at least three sides, connected together by a continuous flexible layer. The base and the roof may be provided with fold lines or grooves extending along a diagonal of each. The surfaces can be made either from a multilayer material consisting of a continuous, flexible layer and rigid parts fixed to said layer or from plastic material and can be partially open and bordered.

A polyhedric structure adapted to be folded down onto its own base, said structure comprising: a base consisting of a polygon; a roof consisting iof a polygon, said polygons of the base and the roof having an even number of sides; (n-1) first lateral surfaces, wherein n is the number of sides of the
A polyhedric structure adapted to be folded down onto its own base, said structure comprising: a base consisting of a polygon; a roof consisting iof a polygon, said polygons of the base and the roof having an even number of sides; (n-1) first lateral surfaces, wherein n is the number of sides of the base polygon, said first lateral surfaces joining said roof to said base and forming a prism, each of said first lateral surfaces having a diaginal line; a side surface free on at least three sides and affixable as an nth lateral surface of said prism, said side surface having a tilting door; and a groove extending along the diagonal line of each said first lateral surface, said grooves being inclined in the same direction, said first lateral surfaces having corners, said corners being connected by at last one continuous, flexible layer, the first lateral surfaces contiguous to said side surface being provided with auxiliary folding lines parallel to the base, placed in the middle of said first lateral surfaces and in contact with said diagonal lines.
