Water closet flange hub assembly

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.

1 . A water closet flange hub assembly for use with a floor comprising: 
 an annular base having a central through opening, said base adapted to be mounted to the floor,    a water closet hub having a tubular and cylindrical pipe dimensioned to be slidably and adjustably positioned through said base through opening, and an outwardly extending toilet mounting flange at one end of said pipe,    means for securing said hub relative to the floor at an adjusted position relative to said annular base.    
   
   
       2 . The invention as defined in  claim 1  and comprising at least one seal disposed between said base and said water closet hub.  
   
   
       3 . The invention as defined in  claim 2  wherein said at least one seal comprises a resilient O-ring.  
   
   
       4 . The invention as defined in  claim 3  wherein said water closet hub includes an annular groove formed around an outer surface of said cylindrical pipe, said seal being positioned in said annular groove.  
   
   
       5 . The invention as defined in  claim 3  and comprising at least two resilient O-rings, said O-rings being positioned around an outer surface of said cylindrical pipe of said water closet hub at axially spaced positions.  
   
   
       6 . The invention as defined in  claim 1  wherein said securing means comprises a threaded fastener.  
   
   
       7 . The invention as defined in  claim 6  wherein said threaded fastener threadably engages the floor.  
   
   
       8 . The invention as defined in  claim 6  wherein a portion of the floor overlaps a portion of said annular base and wherein said threaded fastener threadably engages the floor.  
   
   
       9 . The invention as defined in  claim 1  wherein said water closet hub is made of plastic.  
   
   
       10 . The invention as defined in  claim 9  where said water closet hub is of a one-piece construction.  
   
   
       11 . The invention as defined in  claim 1  wherein said toilet mounting flange includes a pair of diametrically opposed slots dimensioned to receive toilet retaining fasteners.  
   
   
       12 . A water closet flange hub assembly for use with a floor comprising: 
 an annular base having a central through opening, said base adapted to be mounted to the floor,    a water closet hub having a tubular and cylindrical pipe dimensioned to be slidably and adjustably positioned through said base through opening, and an outwardly extending toilet mounting flange at one end of said pipe,    fasteners which secure said hub relative to the floor at an adjusted position relative to said annular base.
