Abstract
A water closet flange hub assembly for use with a floor. The assembly includes an annular base having a central through opening and which is mounted to the floor. A water closet hub includes a tubular and cylindrical pipe which is dimensioned to be slidably and adjustably positioned within the base opening. The hub also includes an outwardly extending toilet mounting flange at one end of the pipe. A fluid seal is disposed between the pipe of the water closet hub and the annular base to fluidly seal the base and hub together at an adjusted position of the water closet hub. The water closet hub is then secured to the floor by fasteners.
Description
- This application claims priority of U.S. Provisional Patent Application Ser. No. 60/501,239 filed Sep. 8, 2003, which is incorporated herein by reference.
- I. Field of the Invention
- The present invention relates to plumbing fittings and, more particularly, to a water closet flange hub assembly.
- II. Description of Related Art
- The previously known water closet flange typically comprise a tubular and cylindrical plastic pipe having an outwardly extending flange adjacent its upper end. The pipe is secured, typically by chemical welding, to the waste plumbing system of the structure so that the flange is level with the building floor. A toilet is then secured to the flange by conventional fasteners.
- In some situations, for example where a new floor covering is installed, the level of the floor changes from its prior level. When this occurs, the flange is no longer even with the floor surface. When this occurs, it has been previously necessary to replace the entire closet flange. Such replacement is highly labor intensive and therefore expensive.
- The present invention provides a water closet hub assembly which overcomes all of the above-mentioned disadvantages of the previously known devices.
- In brief, the water closet flange hub assembly is designed for use with a floor and includes an annular base having a central through opening. This base is adapted to be mounted to the floor and is typically constructed of plastic. Once the base is secured to the floor, the circular through opening faces upwardly through the floor. The lower portion of the base is fluidly connected to the waste system for the structure.
- A water closet hub includes a tubular and cylindrical pipe which is dimensioned to be slidably and adjustably positioned through the base through opening. This water closet hub includes an outwardly extending toilet mounting flange adjacent one end. With the cylindrical pipe of the water closet hub positioned within the base throughbore, the lower surface of the toilet mounting flange abuts against the top of the floor.
- At least one and preferably two resilient O-rings are positioned in between an outer surface of the water closet hub pipe and an inner surface of the base around the through opening. The O-ring seals thus fluidly seal the annular base to the water closet hub at any adjusted position of the water closet hub relative to the base.
- With the cylindrical pipe of the water closet hub positioned within the base, the toilet mounting flange is then secured to the floor using conventional fasteners.
- A better understanding of the present invention will be had upon reference to the following detailed description, when read in conjunction with the accompanying drawing, wherein like reference characters refer to like parts throughout the several views, and in which:
-
FIG. 1 is a perspective exploded view illustrating a preferred embodiment of the present invention; -
FIG. 2 is a longitudinal sectional view illustrating the annular base mounted to a floor; -
FIG. 3 is a longitudinal partial sectional view of a preferred embodiment of the water closet flange; and -
FIG. 4 is a longitudinal sectional view illustrating the assembled water closet flange hub assembly. - With reference first to
FIG. 1 , a preferred embodiment of the water closetflange hub assembly 10 of the present invention is shown. The water closetflange hub assembly 10 includes both anannular base 12 as well as awater closet hub 14. Both theannular base 12 andwater closet hub 14 are preferably of a one-piece plastic construction. - With reference now particularly to
FIG. 2 , theannular base 12 is shown in greater detail and includes a centralcylindrical throughbore 16. Theannular base 12, furthermore, is generally tubular and cylindrical in shape and includes a radially outwardly extendingflange 20 at a position spaced downwardly from an upperopen end 22 of thebase 12. Alower end 24 of thebase 12 is fluidly connected to a waste system 26 (only partially illustrated) of a structure. Typically, thewaste system 26 is also constructed of plastic and thebase 12 is secured to thewaste system 26 by chemical welding. - Still referring to
FIG. 2 , thehub 12 is installed relative to afloor 28 of a structure such that anupper surface 30 of theflange 20 flatly abuts against alower surface 32 of thefloor 28. Theflange 20, and thus thebase 12, is then secured to thefloor 28 by any conventional means, e.g. threadedfasteners 36, which extend throughopenings 38 in theflange 20 and into thefloor 28. - With reference now to
FIGS. 1 and 2 , preferably a plurality of circumferentially spacedopenings 38 are formed through theflange 20 in order to provide a firm attachment of theflange 20, and thus thebase 12, to thefloor 28. Additionally, as best shown inFIG. 1 , oneside 40 of theflange 20 may be removed to enable thebase 12 to fit closely adjacent a building framing member. - With reference now particularly to
FIG. 3 , thewater closet hub 14 is illustrated in greater detail. Thewater closet hub 14 includes acylindrical pipe 50 having an outside diameter less than the inside diameter of the base opening 22 (FIG. 2). A radially outwardly extendingtoilet mounting flange 52 extends radially outwardly from anupper end 54 of thewater closet hub 14. A plurality of circumferentially spacedthroughbores 56 are formed through theflange 52. - Still referring to
FIG. 3 , at least one and preferably twoannular grooves 58 are formed around anouter periphery 60 of thepipe 50 adjacent alower end 62 of thepipe 50. Thegrooves 58 are axially spaced from each other and a resilient O-ring seal 64 is disposed within eachgroove 58. - With reference now to
FIG. 4 , the operation of the present invention will now be described. With thebase 12 secured to thefloor 28 by thefasteners 36 as previously described, the through opening 22 of thebase 12 faces upwardly and adjacent, or slightly recessed, from an upper surface of thefloor 28. Thelower end 62 of thewater closet hub 14 is then inserted through the through opening 22 until thetoilet mounting flange 52 abuts against the top of thefloor 28. Thetoilet mounting flange 52 is then secured to thefloor 28 by conventional fasteners. - Upon insertion of the
water closet hub 14 into thebase 12, the resilient O-rings 64 are compressed in between an outer periphery of thepipe 50 of thewater closet hub 14 and an inner surface of thebase 12. In doing so, theseals 64 fluidly seal thewater closet hub 14 andbase 12 together. - When it is desired or necessary to alter the height of the
toilet mounting flange 52, the fasteners securing thetoilet mounting flange 52 to thefloor 28 are removed and thehub 14 is then removed from thebase 12. After theflooring 28 has been finished, e.g. by adding additional flooring, such as tile, to the top of thefloor 28, thewater closet hub 14 is then reinserted into thebase 12. In doing so, since the height of thefloor 28 has varied, the degree of insertion of thewater closet hub 14 into thebase 12 will vary in accordance with the height of thenew floor 28. However, regardless of the insertion of thewater closet hub 14 into thebase 12, thefluid seals 64 will maintain the seal between thewater closet hub 14 andbase 12 regardless of the adjusted position of thewater closet hub 14 relative to thebase 12. - From the foregoing, it can be seen that the present invention provides a water closet hub assembly in which the height of the toilet mounting flange may be varied as desired to accommodate floors in which the height of the floor has been changed, e.g. by the addition of new flooring. Having described my invention, however, many modifications thereto will become apparent to those skilled in the art to which it pertains without deviation from the spirit of the invention as defined by the scope of the appended claims.
