Abstract:
A closet flange for connecting an outlet of a toilet bowl with a waste water drain conduit through an opening in a floor, the closet flange comprising:an outer flange having an upper surface and a lower surface and having at least two generally opposed first apertures which extend through said outer flange between the upper surface and the lower surface and which are adapted for retaining fasteners for securing the outer flange to a floor, wherein at least a portion of the lower surface is adapted to lie against said floor, and at least two second apertures extending from said lower surface to said upper surface and which are adapted for retaining fasteners connecting said outer flange to a toilet bowl; anda discharge tube rotatably connected to the outer flange, wherein said outer flange is rotatably connected to said discharge tube by a press catch connector, and wherein said press catch connector permits rotation of said discharge tube relative to said outer flange without raising or lowering of said discharge tube relative to said outer flange, said discharge tube including:an interiorly-positioned seal seat located proximate said outer flange, said seat having an inner diameter which defines a first substantially circular opening;a distal end for coupling to said waste water drain conduit; anda continuously curved non-edge bearing tubing section extending between said first substantially circular opening and said distal end to provide a smooth edge-uninterrupted transition therebetween thus sweeping discharge into said waste water drain conduit without clogging, said tubing section defining a curved centerline immediately below and continuously from said first substantially circular opening whereby a vertical distance between said distal end and said flange is minimized.
