Plastic self-relieving curb inlet filter

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Two of the preferred embodiment of the invention are projected from the curb inlet as illustrated in FIG.
1 (isometric view) and depicted in-place in a curb inlet as illustrated in FIG.
2 (isometric view).
The typical embodiment is one-molded piece consisting of a screened grid configuration of vertical members 26 and tubular horizontal members 27 having a uniform cross section as illustrated in FIG.
3 (front view) and FIG.
4 (end view) and an adhesive panel 23.
As the flow/debris accumulation pressure increases, the invention will move/open inward from the fixed position to the self-religning 40 position as illustrated in FIG.
4.
As the flow/debris accumulation pressure decreases, the screened grid will move/return to the original position; all performed without the need for human assistance.
The screened grid configuration of the preferred embodiment consists of uniform sturdy, light-weight vertical members 26, and horizontal members 27 (FIGS.
3, 4, and 5), is typically 29 inches in length and 4 inches in height, such that 2 embodiments of the invention may accommodate the 5 feet.
times.
6 inch opening of a conventional curb inlet.
The adhesive panel 23 is typically 1/4 inches in thickness and projects 11/2 inches in depth.
The screened grid configuration of the preferred embodiment consists of uniform vertical 26 and horizontal 27 members typically 1/4 inches in diameter.
The outer ends of the horizontal members 27 are typically rounded to avoid snagging and personal injury.
Also, the screened grid configuration of rounded members 26 and 27 allow fluids to pass without any significant resistance.
The invention may be manufactured from various conventional light-weight and sturdy materials or resins in prior art regulations, such as polyethylene, polypropylene, acrylonitrile butadiene styrene, polyurethane, vinyl, nylon, rubber, various recyclable and elasticized materials, various plasticized or laminated fibrous materials and fiberglass-resins, foamed plastics of saturated polyester or foamed thermoplastic polyester resins, that can withstand various temperature changes, resist the prodding forces of street sweeping and vacuum cleaning equipment, withstand casual bending without fracturing and return to the original position
