This invention is a structure encompassing a large volume of area used for traffic delineators, warning and instruction signs, and the like. It is characterized by being formed from materials specially formed and hinged in such manner as to be collapsible for storage and transport when not in use. The structure and the method involved comprises a multiplicity (preferably three) of flat items hinged together in an angular relationship to one another when assembled, to encompass a large volume, but at the same time, so as to collapse into a single flat configuration for storage and transportation, by folding two panels to opposite sides of a center panel.

The method for forming a portable and collapsed structure as follows: (1) defining upon a sheet of material having a thickness a first triangular shape having a first, second and third edge, each of which edges is at an angular relationship to each of the other edges; (2) defining upon the same sheet of material a second triangular shape of substantially the same size and shape as the first defined shape, said second shape having a first, second and third edge, each of which edges is at an angular relationship to each of the other edges and wherein the second edge of the second shape is the same as the third edge of the first triangular shape; (3) defining a third shape of substantially the same size and shape as the first shape upon said sheet of material, said third shape having a first, second and third edge, each of which edges is at an angular relationship to each of the other edges and wherein the second edge of the third shape is the same as the third edge of the second shape; (4) reducing the thickness of the article upon one of its sides along the common line of the third edge of the first shape and the second edge of the second shape; (5) reducing the thickness on the other side of said article along the line defining the third edge of the second shape and the second edge of the third shape; (6) forming interengageable portions on the second edge of the first shape and the third edge of the third shape whereby said second edge of the first shape and third edge of the third shape are engageable to form a pyramidal body; (7) folding the first shape against the second shape along the side opposite the side where thickness has been reduced between the said first and second shapes; and (8) folding the third shape against the second shape along the side opposite the side where thickness has been reduced between the said second and third shapes.
