Abstract
A strainer for a waste water aperture in a fluid compartment. The strainer has an upper end with a flange extending outwardly from the upper end and a downwardly extending wall. Positioned between the flange and the bottom of the fluid compartment is a compressible sealing member that secures the strainer to the fluid compartment.
Description
- A strainer in the plumbing field is the threaded fitting in the bottom of a sink, bathtub, or the like through which waste water flows from the receptacle. Strainers usually have valves or the like which control the gravity flow of water therethrough. All the valve assemblies are threadably mounted within a threaded aperture located in the strainer.
- Existing strainers have a vertically disposed externally threaded sleeve which engage corresponding threads on a fitting adjacent a vertically disposed aperture in the bottom of the water receptacle. The upper end of the sleeve terminates in a circular horizontal flange which engages and is sealed with plumber's putty to the bottom of the receptacle around the aperture in the bottom of the receptacle. A hub with a threaded bore and with radially extending spokes is often located in a horizontal plane in the bottom of the strainer to support various closure valves.
- Installation of the strainer can be a messy project. A plumber applies putty to the bottom surface of the strainer, inserts the sleeve into the aperture of the bottom of the receptacle, and pressure is applied to the flange to seal the strainer against the bottom of the receptacle. Due to the pressure, excess putty spreads outside the outer perimeter of the flange and must be wiped away. Thus, a need exists for a better way to install a strainer.
- Therefore, an object of this invention is to provide a strainer that is easier to install.
- This and other objects will become apparent to those skilled in the art.
- A strainer to be placed in the bottom of a fluid compartment. The strainer has an upper end with a flange extending outwardly from the upper end and a downwardly extending wall. The wall extends through an aperture in the bottom of the compartment. A compressible sealing member is positioned between the flange and the bottom of the fluid compartment to secure the strainer to the fluid compartment.
-
FIG. 1 is a partial perspective view of a bathtub with a waste water strainer located in the bottom thereof; -
FIG. 2 is a sectional view of a strainer; and -
FIG. 3 is a sectional view of a strainer. - Numeral 10 designates a fluid compartment or receptacle such as a tub or a sink.
Compartment 10 has abottom 12 with aninterior bottom surface 14. Awaste water aperture 16 is located inbottom 12 and in a preferred embodiment has a shoulder 18 that surrounds the lower portion of the aperture. - A waste water strainer 20 has an
upper end 22 from which a horizontalcircular flange 24 extends. Preferably, the outer perimeter 26 of theflange 24 engages theinterior bottom surface 14. The strainer 20 has a downwardly extendingcylindrical wall 28 andexternal threads 30. In a preferred embodiment the strainer 20 has a center hub 32 having a vertically disposed threaded aperture 34 that is located at the bottom of the strainer 20. A plurality of radially extending arms 36 connect the center hub 32 with the interior bottom portion ofcylindrical wall 28. - A
compressible sealing member 38 is positioned between theflange 24 of the strainer 20 and theinterior bottom surface 14 of thecompartment 10. The sealingmember 38 extends aroundwall 28 to form a seal between the strainer 20 and theaperture 16 of thecompartment 10. Preferably, the sealing member is made of an EVA® foam which compresses to nearly zero. In an alternative embodiment, other foams are used for the sealing member. -
FIG. 3 shows an alternative embodiment of thecompressible sealing member 38. In this embodimentcompressible sealing member 38 is positioned between theflange 24 of the strainer 20 and theinterior bottom surface 14 of thecompartment 10. The sealingmember 38 extends aroundwall 28 to form a seal between the strainer 20 and theaperture 16 of thecompartment 10. The sealingmember 38 additionally extends along the downwardly extendingcylindrical wall 28 and wraps around the bottom of the fluid compartment to engage the bottom surface of thebottom 12 ofcomponent 10 to form the sealing surface. Thus, the sealingmember 38 extends around thebottom 12 as one piece and extends aroundwall 28 to form a seal between the strainer 20 and thebottom 12 ofcompartment 10. - From the disclosure, a strainer that is easier to install has been shown. The use of the sealing member eliminates the need for messy plumber's putty.
- It will be appreciated by those skilled in the art that other various modifications could be made to the device without the parting from the spirit in scope of this invention. All such modifications and changes fall within the scope of the claims and are intended to be covered thereby.
