Curb-style drain filter kit

Abstract

A curb style drain filter kit has a length of flexible filter material of film or mesh with interstices sized to separate small particles from run-off water. The material is wrapped around a conduit which lays in the gutter and fits in a storm sewer inlet. The filter material extends outwardly from the conduit and covers the storm drain grate. An anchor is attached to the outer edge of the material to keep the material flat and covering the grate.

1 . A curb style drain filter kit for preventing silt and debris carried by run-off water from entering the storm drainage system comprising a sieve-like filter material having interstices sized to remove particles of silt from run-off water, said filter material having a first elongated edge and a second elongated edge opposite said first edge, a first open hem along said first edge and a second open hem along said second edge of said material.  
   
   
       2 . A curb style drain filter kit of  claim 1  comprising a tubular conduit telescoped in said first open hem.  
   
   
       3 . A curb style drain filter kit of  claim 2  comprising an anchor telescoped in said second open hem.  
   
   
       4 . A curb style drain filter kit of  claim 1  comprising an anchor telescoped in said second open hem.  
   
   
       5 . A curb style drain filter kit of  claim 1  comprising said material composed of multiple plies.  
   
   
       6 . A curb style drain filter kit of  claim 2  comprising said material composed of multiple plies.  
   
   
       7 . A curb style drain filter kit of  claim 3  comprising said material composed of multiple plies.  
   
   
       8 . A curb style drain filter kit of  claim 7  comprising said multiple plies have different interstice size.  
   
   
       9 . A curb style drain filter kit of  claim 1  wherein said conduit is perforated to allow additional filtering.  
   
   
       10 . A curb style drain filter kit for preventing silt and debris carried by run-off water from entering the storm drainage system comprising an elongated tubular conduit having a first end and a second end and of a length to span a storm drain inlet in a gutter, said first end of said conduit adapted to be disposed in the gutter on one side of the inlet and said second end of said conduit adapted to be disposed in the gutter on the other side of the inlet, a length of filter material having a first end and a free end, said first end wrapped about said conduit, said length adapted to fit beneath a storm drain grate, said filter material being pervious to run-off water whereby said material filters run-off water entering the inlet and said conduit provides a passageway for excess run-off water by-passing the inlet.  
   
   
       11 . A curb style drain filter kit of  claim 10  comprising an open hem in said first end of said material, said conduit telescoped into said open hem.  
   
   
       12 . A curb style drain filter kit of  claim 10  comprising an open hem in said free end of said material.  
   
   
       13 . A curb style drain filter kit of  claim 10  wherein said material is cut to fit a sewer grate.  
   
   
       14 . A curb style drain filter kit of  claim 10  wherein said conduit is cut to fit a sewer grate opening.  
   
   
       15 . A curb style drain filter kit of  claim 10  wherein said conduit is perforated to allow additional filtering.  
   
   
       16 . A curb style drain filter kit for preventing silt and debris carried by run-off water from entering the storm drainage system comprising an elongated tubular conduit having a first end and a second end; a length of filter material having a_first end and a free end, said first end secured along a length of said material forming an aperture sized to receive said conduit; whereby said conduit is cut at a job site to a length that spans a storm drain inlet in a gutter, said material is cut at the job site to a length that spans a storm drain grate, wherein said conduit is positioned with said aperture and said material is anchored to said drain upon placement beneath said grate, said filter material being pervious to run-off water whereby said material filters run-off water and said conduit provides a passageway for excess run-off water by-passing the inlet.
