Abstract:
A plastic self-relieving curb inlet filter, formed from a group of plasticized materials, for allowing fluids to pass and restricting the passage of debris, various sized sediment, small animals, children, and toys into a curb inlet opening having horizontal and vertical dimensions, a perimeter with boundaries and a front top inside wall, said plastic self-relieving curb inlet filter comprising:a molded plastic self-relieving curb inlet filter, of substantially the same boundaries as the perimeter of said curb inlet, having a top horizontal attachment panel, said top horizontal attachment panel, having thickness, depth, an adhesive surface, and an outer edge, wherein said top horizontal attachment panel has a horizontal dimension less than the horizontal dimension of said curb inlet opening; anda grid configuration of hydraulic openings, consisting of tubular horizontal members, of equal length and thickness of said top horizontal attachment panel, positioned parallel to and below said top horizontal attachment panel; andtubular vertical members, of equal thickness to said top horizontal attachment panel and said tubular horizontal members, positioned perpendicular to said tubular horizontal members, and joined at 90 degrees to said outer edge of said top horizontal attachment panel, and with vertical dimension less than the vertical dimension of opening of said curb inlet; andwhereas adhesive is fixed to said adhesive surface of said top horizontal attachment panel to attach said top horizontal attachment panel to said front top inside wall of said curb inlet opening, whereas said plastic self-relieving curb inlet filter can be configured with a plurality of said tubular horizontal and vertical members positioned for various sizes of said hydraulic openings; andwhereas the accumulation of debris or sediment moves said plastic self-relieving curb inlet filter from a fixed position to allow said debris or sediment to pass into said curb inlet opening, wherein said plastic self-relieving curb inlet filter returns to said fixed position, after allowing said debris or sediment to pass therethrough.
