Drainage fitting for a toilet

Abstract

A drainage fitting for use with a toilet having a toilet horn and with a toilet flange having a ledge upwardly adjacent an outlet includes an outer wall having a tapered-cylindrical or cylindrical configuration and defining a channel therethrough for receiving the horn of a toilet therein. The fitting includes an upper segment for receiving the horn and a lower segment configured to nest in the ledge of a toilet flange for interfacing the toilet with a plumbing drainpipe. The drainage fitting enables a toilet to be mounted to a drainpipe without using a wax ring. Alternatively, the drainage fitting may include an enlarged collar having upwardly extending toilet mounting bolts that eliminates the need to use a separate toilet flange.

 a tubular member having an outer wall defining open top and bottom ends and defining a channel therebetween;    a collar positioned between said top and bottom ends and extending outwardly from said outer wall for supporting said fitting in an upright configuration;    wherein said channel has a top diameter at said top end that is larger than a diameter of said channel at said collar; and    wherein the toilet horn is receivable in said channel top end.    
   
   
       2 . The fitting as in  claim 1  wherein said collar has a configuration complimentary to a configuration of the toilet flange ledge and said fitting bottom end has a configuration complimentary to a configuration of the toilet flange outlet, whereby said fitting is receivable in the toilet flange.  
   
   
       3 . The fitting as in  claim 2 , further comprising a seal located in said channel for sealing said fitting to the toilet horn when the toilet horn is received in said channel top end.  
   
   
       4 . The fitting as in  claim 1 , further comprising: 
 a plurality of toilet attachment bolts extending upwardly from said collar;    wherein said collar is attachable to a floor surface; and    wherein said fitting bottom end is attachable to a drain pipe.    
   
   
       5 . The fitting as in  claim 4 , further comprising a seal located in said channel for sealing said fitting to the toilet horn when the toilet horn is received in said channel top end.  
   
   
       6 . The fitting as in  claim 1 , further comprising a seal located in said channel above said collar for sealing said fitting to the toilet horn when the toilet horn is received in said channel top end.  
   
   
       7 . The fitting as in  claim 6 , wherein said seal is an O-ring.  
   
   
       8 . The fitting as in  claim 1 , wherein: 
 said collar separates said fitting into upper and lower segments; and    said channel includes a constant diameter throughout said lower segment.    
   
   
       9 . The fitting as in  claim 1 , wherein said top and bottom ends have annular configurations.  
   
   
       10 . The fitting as in  claim 8 , wherein the toilet horn has a tapered configuration that is complementary to a configuration of said fitting upper segment for smooth reception therein.  
   
   
       11 . The fitting as in  claim 1 , wherein the toilet horn has a cylindrical configuration.  
   
   
       12 . A drainage fitting for use with a toilet having a toilet horn, said fitting comprising: 
 a tubular member having an outer wall defining open top and bottom ends and defining a channel therebetween, said channel having a top diameter at said top end and a bottom diameter at said bottom end;    a collar being positioned between said top and bottom ends and extending outwardly from said outer wall for supporting said fitting in an upright configuration and dividing said tubular member into upper and lower segments;    wherein said channel has a tapered-cylindrical configuration at said upper segment and said channel has a cylindrical configuration at said lower segment, said channel top diameter being larger than a diameter of said channel at said collar; and    wherein the toilet horn is receivable in said tubular member upper segment through said channel top end.    
   
   
       13 . The fitting as in  claim 12  for use with a toilet flange having a ledge upwardly adjacent an outlet, wherein said collar has a configuration complimentary to a configuration of the toilet flange ledge and said fitting bottom end has a configuration complimentary to a configuration of the toilet flange outlet, whereby said fitting is receivable in the toilet flange.  
   
   
       14 . The fitting as in  claim 12 , further comprising: 
 a plurality of toilet attachment bolts extending upwardly from said collar for attachment to the toilet;    wherein said collar has a bottom face attachable to a floor surface; and    wherein said fitting bottom end is attachable to a drain pipe.    
   
   
       15 . The fitting as in  claim 12 , wherein the toilet horn has a configuration selected from the group consisting of cylindrical and tapered-cylindrical, said fitting further comprising a seal located in said channel above said collar for sealing said fitting to the toilet horn when the toilet horn is received in said channel top end.  
   
   
       16 . A drainage fitting for use with a toilet having a toilet horn, said fitting comprising: 
 a tubular member having an outer wall defining open top and bottom ends and a channel therebetween;    a collar extending outwardly from said outer wall, said collar being positioned between said top and bottom ends for supporting said fitting in an upright configuration;    wherein said outer wall includes a tapered configuration such that a diameter of said channel becomes smaller said top end to said collar; and    wherein the toilet horn is receivable through said channel top end.    
   
   
       17 . The fitting as in  claim 16  for use with a toilet flange having a ledge upwardly adjacent an outlet, wherein said collar has a configuration complimentary to a configuration of the toilet flange ledge and said fitting bottom end has a configuration complimentary to a configuration of the toilet flange outlet, whereby said fitting is receivable in the toilet flange.  
   
   
       18 . The fitting as in  claim 17 , wherein the toilet horn has a configuration selected from the group consisting of cylindrical and tapered-cylindrical, said fitting further comprising a seal located in said channel above said collar for sealing said fitting to the toilet horn when the toilet horn is received in said channel top end.  
   
   
       19 . The fitting as in  claim 16 , further comprising: 
 a plurality of toilet attachment bolts extending upwardly from said collar;    wherein said collar has a bottom face attachable to a floor surface; and    wherein said fitting bottom end is attachable to a drain pipe.    
   
   
       20 . The fitting as in  claim 19 , wherein the toilet horn has a configuration selected from the group consisting of cylindrical and tapered-cylindrical, said fitting further comprising a seal located in said channel above said collar for sealing said fitting to the toilet horn when the toilet horn is received in said channel top end.
