Easily formable grid for windows and the like

Claim 1

A grid, having a size which is selectable to conform to a window opening, or the like, comprising: (a) multiple couplings having flat, parallel opposite side walls, and (b) elongated grid members having a slidable telescopic interfit with said couplings to define (i) peripheral frame members, and (ii) other members which extend between the frame members, (c) the grid members being hollow along their lengths, and having flat parallel opposite side walls, the widths of each of said grid members in directions parallel to said side walls being everywhere at least about three times the thickness of each of said grid members in directions normal to and between said flat side walls, said widths being between 1/2 and 1 inch, and said thicknesses being between 1/8 and 1/4 inch, (d) the couplings defining tongues telescopically closely slidably endwise interfitting the ends of said hollow grid members as the tongue slide endwise into the grid members, corresponding entire outer side walls of the couplings and members being co-planar, (e) the couplings and grid members consisting of polyvinylchloride material, the grid members being cuttable to desired lengths, (f) and including interengaged stop shoulders on said couplings and members limiting tongue reception into said members, each of said tongues extending from a plane of said coupling shoulder and defining a root end where said tongue meets said plane of said shoulder the said shoulders extending about the tongues at the root ends thereof, the couplings and members having exterior flush surfaces, (g) the tongues and grid members having interengaged flat slide surfaces at opposed sides thereof and interengaged curved slide surfaces along edges thereof, (h) and including a glass window pane at one side of which the grid is located to extend parallel to the pane, thereby to create a Colonial window appearance, certain tongues adjusted in said members so that the grid fits the elongated window pane, the grid members being attached to the pane.
