Self-Sealing Closet Flange

Abstract

A closet flange system with attached bolts on the anterior surface and a beveled edge on the posterior surface, a groove on the anterior surface for an O-ring to form a seal between the bottom of the toilet and the anterior edge of the closet flange. The anterior surface is connected to a midsection of the closet flange, which includes a keeper ring, securing the position of the closet flange within a drain pipe by preventing removal. An additional O-ring may be positioned on the midsection to block fluid and gas from the drain from rising to contact the keeper ring or escaping outside of the drain pipe. The beveled edge guides the end of the flange into the drain pipe. The system includes bolts which attach the closet flange to the bottom of the toilet before the system is attached to the drain pipe at the floor surface.

What is claimed: 
     
         1 . A closet flange system for connecting a toilet to a drain, said closet flange system comprising:
 a rim with at least one opening, wherein said rim consists of an upper surface and a lower surface;   a tube with a first end and a second end; and   at least one bolt.   
     
     
         2 . The closet flange system of  claim 1 , wherein said opening extends from the upper surface of said rim to the lower surface of said rim. 
     
     
         3 . The closet flange system of  claim 1 , wherein said first end of said tube is connectedly attached to said opening at said lower surface of said rim. 
     
     
         4 . The closet flange system of  claim 1 , wherein at least one of said bolts protrudes from said upper surface of said rim. 
     
     
         5 . The closet flange system of  claim 1 , wherein a first circular depression is positioned on said rim, outside said opening of said rim, wherein said first circular depression is positioned within the outer boundary of said rim. 
     
     
         6 . The closet flange system of  claim 1 , wherein said second end is a smaller diameter than said first end. 
     
     
         7 . The closet flange system of  claim 1 , wherein a band is positioned at a point between said first end of said tube and said second end of said tube, wherein said band lies at the exterior of said tube. 
     
     
         8 . The closet flange system of  claim 7 , wherein said band is comprised of at least one or more protrusions, wherein said protrusions contribute resistance to prevent the removal of said closet flange system from a drain pipe. 
     
     
         9 . The closet flange system of  claim 8 , wherein a second circular depression is positioned at a point between said first end of said tube and said second end of said tube, wherein said circular depression lies at the exterior of said tube. 
     
     
         10 . The closet flange system of  claim 1 , wherein a band is positioned at a point between said first end of said tube and said second end of said tube, wherein said band lies at the interior of said tube. 
     
     
         11 . The closet flange system of  claim 10 , wherein said band is comprised at least one or more protrusions, wherein said protrusions contribute resistance to prevent the removal of said closet flange system from a drain pipe. 
     
     
         12 . The closet flange system of  claim 11 , wherein a second circular depression is positioned at a point between said first end of said tube and said second end of said tube, wherein said circular depression lies at the interior of said tube. 
     
     
         13 . A method comprising
 a) Inserting an O-ring into a depression on the rim of a closet flange;   b) Inserting a number of bolts connectedly attached to the upper surface of a rim of said closet flange into holes precut into the bottom of a toilet;   c) Placing an O-ring around the exterior of said closet flange;   d) Placing a beveled second end of said closet flange into a drain pipe at a floor surface;   e) inserting said closet flange into said drain pipe until the bottom of said toilet is adjacent to said floor surface;   
     
     
         14 . A method comprising
 a) Inserting a number of bolts connectedly attached to the upper surface of a rim of said closet flange system into holes precut into the bottom of a toilet;   b) Placing an O-ring around the exterior of said closet flange;   c) Placing a beveled second end of said closet flange into a drain pipe at a floor surface;   d) Inserting said closet flange into said drain pipe until the bottom of said toilet is adjacent to said floor surface;   
     
     
         15 . A method comprising
 a) inserting an O-ring into a depression on the rim of a closet flange;   b) inserting a number of bolts connectedly attached to the upper surface of a rim of said closet flange into holes precut into the bottom of a toilet;   c) Placing a beveled second end of said closet flange into a drain pipe at a floor surface;   d) Inserting said closet flange into said drain pipe until the bottom of said toilet is adjacent to said floor surface;
