Abstract: A vehicle sun-shade of the louvre type formed from plastic wherein sagging due to high temperature imparted to the plastic is reduced by the use of a spacer rod passing through bushes in which it is frictionally engaged, the bushes being in the louvres and between their ends.

Abstract: Apparatus constituting a grill for use as a gate, door, window or the like, adjustable for fitting upon a frame to cover an opening.

Abstract: A series of upright, longitudinally extending baffles are supported in parallel array, with the transverse or secondary baffles being formed by twisting out of the webs of the primary baffles an area initially separated by slots which leave a stem connecting the secondary baffle with the web at two opposed positions, normally the top and bottom. When the secondary baffle is twisted, each of the webs is twisted, as to 90.degree., to support the secondary baffle transversely to the primary baffles. Normally, the secondary baffles extend the same distance to each side of the corresponding primary baffle. The secondary baffles of one primary baffle are normally interspaced with the secondary baffles of the adjacent primary baffles.

Abstract: A decorative grille having a substantially rectangular frame in which each of the side members includes a substantially C-shaped channel section and a mounting flange extending substantially coplanar with a leg of the channel section. A plurality of spaced, parallel rods extend between two parallel side members of the frame. The rods have end portions which extend into the channel sections of the side members and are secured thereto by screws extending through the base of the channel sections and threaded into the rods. A plurality of plastic decorative grille elements are mounted in rows between adjacent rods, and between each of the other two side members of the frame and the adjacent rods. The grille elements which are adjacent a rod are interconnected to each other through the rods.

Abstract: Two U-shaped clamps which are adapted to be fastened to spaced-apart mounting channels on the rear of a shutter are joined together by a pliable spacer strip which extends between the clamps and spaces them a predetermined distance apart to match the distance between the spaced channels. The spacer strip enables the clamps to be attached to a building wall in position to support the shutter without the necessity of measuring the distance between the clamps. The pliability of the spacer strip enables the clamps and the attached spacer strip to be conveniently carried in a pocket prior to installation. The spacer strip preferably extends beyond the side edge of the clamps to serve as a gauge to locate the shutter a selected distance from the window frame side.
