Definitions

  • This application relates generally to devices for connecting plumbing fixtures to waste drain conduits, and more particularly to the combination of a specially configured flexible sleeve and a closet flange, which mounts a water closet (toilet) on a supporting floor surface and also provides a tight sealed interconnection between the water closet (toilet) and the water waste drain pipe, allowing a good connection even between uneven outlets.
  • Water closets also called toilets, are waste disposal devices commonly installed in most bathrooms. These kinds of plumbing appliances generally have a water storing receptacle called a water tank that is attached to a siphon seat-shaped bowl called toilet bowl. Periodically, waste is removed from the toilet bowl by flushing, thereby allowing water to drain from the water tank through the toilet bowl and into a waste drainpipe. In order to work, however, the toilet bowl must be connected to the waste drainpipe by fluid carrying conduits. Typically, the toilet bowl will sit flat on a floor and connect with a water closet outer flange. The water closet outer flange in turn connects with conduits leading to a waste drainpipe.
  • Existing toilet flanges often include a conduit portion for passing the waste fluids through the floor (upon which the toilet sits), a number of openings to fasten the flange to the floor, and other openings to attach the toilet bowl to the flange itself. Additionally, there may be an appropriate seat for a toilet seal, which typically may be made either from wax or by a relatively high-density foam or rubber.
  • a problem associated with the previously described apparatuses is that even though they provide some flexibility, both are comprised of rigid connecting conduits, and therefore provide limited flexibility and depth connection distances.
  • U.S. Pat. No. 3,967,836 has a maximum offset of 13 ⁇ 4′′ (one and three quarter inches), which cannot be exceeded; and U.S. Pat. No. 6,052,839 requires a larger maximum offset.
  • the problem with the apparatus described in U.S. Pat. No. 6,052,839 is its minimum offset. More specifically, because it has a connecting rigid conduit in the shape of an elbow, its use is limited to angled connections. Moreover, this shape requires that the vertical distance between the toilet bowl discharge and the waste drain pipe outlet should be at least about 5-6 inches deep.
  • the improved flange has a flexible conduit (i.e. sleeve) portion for carrying fluids and connecting to the waste drain pipe outlet, and such a flexible sleeve will facilitate its installation even between offset, uneven or angular outlets.
  • a flexible conduit i.e. sleeve
  • an improved flange apparatus for connection to a plumbing fixture, such as a toilet
  • the improved flange may comprise an anchoring element or outer flange that is connected to a flexible conduit tube or flexible sleeve, to which is attached an O-ring type of gasket.
  • the improved flange can connect a toilet bowl outlet to a waste drainpipe outlet without any flow reduction between both connecting elements.
  • a further aspect of the improved flange allows the connection between a toilet bowl discharge and a waste drainpipe outlet that are not aligned with each other.
  • Another aspect of the improved flexible sleeve allows the connection between a toilet bowl discharge and a horizontal waste drainpipe outlet.
  • a further aspect of the flexible sleeve prevents any type of leakage or dripping between the toilet bowl discharge and the waste drainpipe outlet.
  • Another aspect of the flexible sleeve is an outer flange element able to firmly anchor a plumbing fixture to a surface.
  • Yet another aspect of the improved flange eliminates the need for using a wax seal or a rubber foam seal in the installation of a toilet, because of the seal provided by the joint between the toilet outlet and the flexible sleeve.
  • a further aspect of the improved flange is an O-ring type of gasket mounted on the flexible sleeve that provides a tight seal between the outer surface of the flexible sleeve and the inner surface of the waste drainpipe in which is connected.
  • the flexible sleeve can be implemented in a variety of sizes or diameters, including, for example, 3 inch (7.5 cm) and 4 inch (10 cm) diameters.
