DETAILED DESCRIPTION

[0070] FIG. 1 shows an embodiment of a toilet flange apparatus 100 having a flange portion 102 which has a flange circumferential groove 110 which receives a first O-ring 406 (shown in FIG. 4), where the flange portion 102 and the flange circumferential groove 110 and the first O-ring 406 cooperate to form a seal with a lower portion of a toilet 904 (shown in FIG. 9). An at least one fastener 106 is used to tighten the flange portion 102 to the lower portion of the toilet 904. Fasteners 106 may include bolts, other threaded fasteners, clips, pins, and any other mechanical fastening mechanisms known in the art. In some embodiments, the fasteners 106 are formed as a portion of the flange portion 102. Although an O-ring 406 is specifically noted, one skilled in the art will appreciate that any elastomeric sealing member may be used, and that the circumferential groove 112 may have a size and dimension to accommodate such sealing members. The toilet flange apparatus 100 may be made from metal, plastic, polymer, ceramic, composites, or any other material known in the art.

[0071] The toilet flange apparatus 100 includes a pipe portion 104 and a circumferential gripping ring 108 having plurality of gripping projections 114 that grip the inside of a drain pipe 908 (shown in FIG. 9). The pipe portion 104 also includes a side circumferential groove 112 for receiving a second O-ring 408 (shown in FIG. 4) that forms an air-tight and liquid-tight seal against the inside of the drain pipe 908. The gripping ring 108 may be made from metal, plastic, or any other material that may be flexibly biased.

[0072] Also shown are weld spots 118 on the circumference of the circumferential gripping ring 108. Although weld spots 118 are illustrated, it will be clear to those skilled in the art that other thermal processes, adhesives, and mechanical fasteners, are contemplated for attaching the circumferential gripping ring 108 to the channel guide ring 302. In some embodiments, the circumferential gripping ring 108 and the channel guide ring 302 are formed from the same piece of material.

[0073] In this embodiment, the pipe leading end 116 has a beveled leading end, with an inside pipe portion wall extending downward lower than an outside pipe portion wall, to provide easy insertion of the toilet flange apparatus 100 into the drain pipe 908 (shown in FIG. 9).

[0074] FIG. 2 shows an embodiment of a toilet flange apparatus 100 having a flange portion 102 which has a flange circumferential groove 110 which receives a first O-ring 406 (shown on FIG. 4), where the flange portion 102 and the flange circumferential groove 110 and the first O-ring 406 cooperate to form a seal with a lower portion of a toilet 904 (shown in FIG. 9). An at least one fastener 106 is used to tighten the flange portion 102 to the lower portion of the toilet 904.

[0075] The toilet flange apparatus 100 includes a pipe portion 104, and shown on the outside of the pipe portion 104 is the circumferential channel 202, having a circumferential channel deep portion 204, and an adjacent circumferential recess 206 to accommodate the circumferential gripping ring 108 (shown in FIG. 1 and FIG. 3). The circumferential channel 202 allows the circumferential gripping ring 108 to rotate with respect to the pipe portion 104. As a result, once the toilet flange apparatus 100 has been inserted into the drain pipe 908, the toilet flange apparatus 100 can be rotationally adjusted with respect to the drain pipe 908 (shown in FIG. 9) in the toilet flange apparatus 100 installation process. In particular, it will be appreciated that the toilet flange apparatus 100 can be rotationally adjusted with respect to the drain pipe 908 by 360 or more after the toilet flange apparatus 100 has been irreversibly connected to the drain pipe 908. Therefore, a toilet, once installed, will have 360 or more freedom of rotation, barring installation environment constraints, after being irreversibly connected to the drain pipe 908.

[0076] The pipe portion 104 also includes a side circumferential groove 112 for receiving a second O-ring 408 (shown in FIG. 4) that forms an air-tight and liquid-tight seal against the inside of the drain pipe 908. Although an O-ring 408 is specifically noted, one skilled in the art will appreciate that any elastomeric sealing member may be used, and that the circumferential groove 112 may have a size and dimension to accommodate such sealing members.
