Means for Covering the Flange of a Waste Water Strainer

Abstract

A waste water insert has a cylindrical wall surrounding a vertical cylindrical bore. A horizontal flange extends outwardly from the upper end of the wall and has a lip formed on its outer periphery. The horizontal flange of the waste water insert is super-imposed over the horizontal flange of a waste water strainer located in a bathtub, sink or the like. The cylindrical wall of the insert extends downwardly through the cylindrical wall of the waste water strainer with the two walls being spaced from each other by virtue of the cylindrical wall of the insert having a smaller diameter than that of the strainer. One or more grooves are within the cylindrical wall of the insert and receive resilient rings that engage the cylindrical wall of the strainer.

1 . A waste water insert adapted to be associated with a strainer that includes a cylindrical wall having an inner surface of a first diameter, comprising:
 a flange;   a wall extending from said flange, said wall having a second diameter such that said wall is spaced from the inner surface of the strainer wherein no portion of said insert contacts the inner surface of the strainer;   and a resilient member associated with an outer surface of said wall and the inner surface of the strainer.   
   
   
       2 . The device of  claim 1  wherein said resilient member is an O-ring. 
   
   
       3 . The device of  claim 1  wherein said flange of said insert rests on a flange of the strainer wherein said wall extends downwardly into an opening defined by the cylindrical wall of the strainer. 
   
   
       4 . The device of  claim 4  wherein said wall includes a groove that receives the resilient member. 
   
   
       5 . The device of  claim 4  wherein said wall includes a second groove for receiving a second resilient member that engages the strainer. 
   
   
       6 . In combination with a fluid compartment having a bottom with a waste water strainer mounted in said bottom, said strainer having a first cylindrical wall with a bottom edge surrounding a cylindrical opening extending through the bottom of said compartment, and a first flange extending outwardly from a level above and adjacent to said cylindrical opening and positioned on the bottom of said compartment:
 a waste water insert comprising a second cylindrical wall, said second cylindrical wall defining a cylindrical bore and having an upper end with a second flange extending therefrom;   said second cylindrical wall being spaced from said first cylindrical wall wherein no portion of said second cylindrical wall contacts said first cylindrical wall;   and a resilient ring engaged on an outer surface of said second cylindrical wall and the strainer.   
   
   
       7 . The combination of  claim 6  wherein said insert has a groove that receives said resilient ring. 
   
   
       8 . The combination of  claim 7  wherein said insert includes a second groove for receiving a second resilient ring that engages the strainer. 
   
   
       9 . The combination of  claim 1  wherein said second flange rests on the first flange wherein said second cylindrical wall extends downwardly into the cylindrical opening defined by said first cylindrical wall. 
   
   
       10 . The combination of  claim 6 , wherein said second flange includes a lip that covers a portion of an outer edge of the first flange. 
   
   
       11 . A waste water insert adapted to be associated with a strainer mounted in a fluid compartment, comprising:
 a downwardly extending cylindrical wall that surrounds a center opening, said downwardly extending cylindrical wall having a diameter less than a diameter of a cylindrical wall of a waste water strainer adapted to receive said insert, said downwardly extending cylindrical wall extending into a cylindrical opening of said waste water strainer,   a circular flange extending outwardly from said central opening superimposable over a flange of the waste water strainer, said flange adapted to rest on the flange of said waste water strainer,   a resilient O-ring member fitted about the downwardly extending cylindrical wall and that contacts the cylindrical wall of the waste water strainer to hold the insert in place so that a space exists between the downwardly extending cylindrical wall and the cylindrical wall of the waste water strainer.   
   
   
       12 . The waste water insert of  claim 11  wherein said insert has a groove that receives the resilient O-ring member. 
   
   
       13 . The waste water insert of  claim 12  wherein said insert includes a second groove for receiving a second resilient O-ring member. 
   
   
       14 . The waste water insert of  claim 11  wherein said fluid compartment comprises a tub or a sink. 
   
   
       15 . The waste water insert of  claim 11  wherein said flange has a periphery terminating in a downwardly extending lip. 
   
   
       16 . The waste water insert of  claim 11  wherein said downwardly extending cylindrical wall is centered within the cylindrical wall of the waste water strainer.
