Abstract
A grille for use as a sun screen, decorative facing, vision barrier or the like is made up of a multiplicity of modular pieces, each of which is of uniform cross section along its length and has walls having spaced-apart, parallel edges defining a base plane and a portion intermediate the edges spaced from the base plane in one direction. An edge flange extends from each edge of the walls of the piece in a direction generally perpendicular to the base plane and opposite from the said one direction, and a pair of spaced-apart slot flanges extends from the intermediate portion of the walls in the said one direction and generally perpendicular to the base plane. The slot flanges define between them a slot that opens generally away from the base plane, the slot having a width at a location nearer the base plane that is greater than its width at a location farther from the base plane. The configuration of the edge flanges is such that adjacent edge flanges of a side-by-side pair of pieces are received in the slot flange of a third piece. A nail-like element driven between the edge flanges of the adjacent pieces urges those edge flanges into tight frictional engagement with the slot flange on the third piece rigidly to interconnect the pieces.
