Closet flange seal

Abstract

A water closet assembly and/or closet flange seal wherein the closet flange seal includes a horn section, a body section, and a sealing fin each formed of a material having a Shore A hardness of less than about 83. The horn section includes a connecting flange, a conical wall, and a ring end wall with the conical wall being integral with and interconnecting the connecting flange and ring end wall. The body section is integral with the horn section and includes a tubular body with an outer face, a first end integral with the horn section, and a second end. The sealing fin extends outwardly from the outer body face, circumscribes the body, and is oriented in a predetermined angle relative to the outer face.

1 . A closet flange seal comprising:

       2 . The closet flange seal of  claim 1  wherein the material has a Shore A hardness of between about 73 and about 81. 
   
   
       3 . The closet flange seal of  claim 1  wherein the material has a Shore A hardness of between about 73 and about 77. 
   
   
       4 . The closet flange seal of  claim 1  wherein the material has a Shore A hardness of about 75. 
   
   
       5 . The closet flange seal of  claim 1  wherein the conical wall thickness is approximately 52% of the body wall thickness between said sealing fin and horn section. 
   
   
       6 . The closet flange seal of  claim 1  wherein the sealing fin has an inner surface, an outer surface, a first end integral with the body, and a second free end and wherein the inner and outer surfaces converge toward the second free end. 
   
   
       7 . The closet flange seal of  claim 1  wherein the predetermined fin angle includes an inner surface being oriented relative to the outer face of the body at an angle of about 46 degrees. 
   
   
       8 . The closet flange seal of  claim 7  wherein the predetermined fin angle includes an outer surface relative to the outer face of the body wall at an angle of about 27 degrees. 
   
   
       9 . The closet flange seal of  claim 1  further including an adhesive positioned on said connecting flange to seal against the water closet. 
   
   
       10 . The closet flange seal of  claim 9  wherein the adhesive is a hot melt adhesive applied at an elevated temperature providing a mechanical bond with the connecting flange. 
   
   
       11 . A water closet assembly comprising:
 a water closet having a horn;   a discharge pipe;   a closet flange coupled to said water closet and said discharge pipe; and   a closet flange seal disposed between the horn and closet flange to provide a seal therebetween, said closet flange seal having a horn section, a body section, and a sealing fin extending outwardly from an outer face of said body section, each of the horn section, body section and sealing fin being formed of one piece of material having a Shore A hardness of less than about 83, wherein:   the body section is integral with the horn section and the body section includes a tubular body wall with an outer face, a first end integral with the horn section, and a second end, the body section further including a sealing fin extending outwardly from the outer face, circumscribing the body, and oriented at a predetermined angle relative to the outer face,   the sealing fin is formed of the same material as the body and horn sections,   the sealing fin sealingly engages an inner surface of the closet flange,   the horn section includes a connecting flange, a conical wall, and a ring end wall, the conical wall being integral with and interconnecting the connecting flange and ring end wall, and   the body wall has a substantially uniform thickness between said sealing fin and said ring end wall and the conical wall has a thickness less than the substantially uniform body wall thickness between said sealing fin and said ring end wall.   
   
   
       12 . The water closet assembly of  claim 11  wherein the material has a Shore A hardness of between about 73 and about 81. 
   
   
       13 . The water closet assembly of  claim 11  wherein the material has a Shore A hardness of between about 73 and about 77. 
   
   
       14 . The water closet assembly of  claim 11  wherein the material has a Shore A hardness of about 75. 
   
   
       15 . The water closet assembly of  claim 11  wherein the sealing fin has an inner surface, an outer surface, a first end integral with the body, and a second free end and wherein the inner and outer surfaces converge toward the second free end. 
   
   
       16 . The water closet assembly of  claim 15  wherein the predetermined fin angle includes an inner surface being oriented relative to the outer face of the body at an angle of about 46 degrees. 
   
   
       17 . The water closet assembly of  claim 16  wherein the predetermined fin angle includes an outer surface relative to the outer face of the body wall at an angle of about 27 degrees. 
   
   
       18 . The water closet assembly of  claim 11  wherein said closet flange couples the water closet and discharge pipe to a floor, wherein the horn section of the closet flange seal includes a connecting flange defining an upper sealing surface, and wherein the water closet assembly further includes a seal material sealingly engaging the connecting flange and water closet. 
   
   
       19 . The water closet assembly of  claim 11  wherein the horn section includes a connecting flange and the water closet assembly further includes an adhesive sealingly engaging said connecting flange and water closet. 
   
   
       20 . The water closet assembly of  claim 19  wherein the adhesive is a hot melt adhesive applied to said connecting flange at an elevated temperature to create a mechanical bond with the connecting flange.
