ABSTRACT:
A grille for use as a sunscreen, decorative facing, vision barrier and the like is made up of a multiplicity of modular pieces, each of which is of uniform cross section along its length. Each piece has walls terminating in spaced-apart parallel edges that define a base plane of the piece, and each piece is paired with another piece by bringing the edges of the two pieces together to produce a closed cell. An edge flange extends outwardly from a portion of the walls adjacent each edge of the piece, and a pair of closely-spaced, parallel slot flanges extend outwardly from a portion of the walls and define an outwardly open slot that is centered on a medial plane perpendicular to the base plane and parallel to the edges of the piece. The slot is, moreover, spaced from the line of intersection between the base plane and the medial plane, which line may be considered the axis of the piece, a distance substantially equal to one-half the perpendicular distance between the edge flanges. The two pieces that form each cell are interconnected by reception of the edge flanges of that cell in the slots of adjacent cells, the flanges when placed together matching the slot in cross section and being urged apart into tight frictional engagement with the slot flanges by a nail-like element.
