Definitions

  • the present disclosure relates generally to devices for connecting conduits, such as plumbing fixtures to waste drain conduits, and more particularly to a flexible seal, including a specially configured flexible sleeve, which mounts to a closet flange and also provides a sealed interconnection between a water closet (toilet) and a water waste drain pipe.
  • a flexible seal including a specially configured flexible sleeve, which mounts to a closet flange and also provides a sealed interconnection between a water closet (toilet) and a water waste drain pipe.
  • Related methods for interconnecting conduits are also described.
  • Water closets also called toilets, are waste disposal devices commonly installed in most bathrooms. These kinds of plumbing appliances generally include a water-storing receptacle called a water tank that is attached to a siphon seat-shaped bowl called a 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 rigid water closet flange. The water closet 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.
  • Toilets are installed and located in accordance with interior decorating aesthetics of the bathroom. The location of the toilet is determined by the location of the waste drainpipe in the floor, and logically, this will determine the location of the toilet bowl discharge and hence the location of the outlet flange. In addition, toilets are placed on varying heights of a finished floor. However, in making openings through floors and in making the connection between the toilet bowl discharge and the waste drainpipe, there is some likelihood that the toilet bowl opening will be in an awkward or inconvenient place.

  • the flexible sleeve is operable to be connected to an upper surface of the member.
  • the modular spacer is operable to couple the modular spacer to the member..

  • FIGS 1A and IB illustrate a flexible seal apparatus 10 for connecting between a plumbing fixture discharge 12 and a waste drainpipe outlet 14 or a waste flange 15.
  • the seal apparatus 10 includes a supporting member 16 and a sleeve 18 disposed through an aperture of the supporting member 16.
  • the sleeve 18 is integrally formed with the supporting member 16 as a single piece, while in other embodiments, the sleeve 18 is removably seated on the supporting member 16.
  • the supporting member 16 may be ring shaped and may be constructed of a substantially rigid material.
  • One or more modular spacers 17 may be coupled to a lower surface of the supporting member 16. As shown in Fig. 1A, the modular spacer 17 may be separated circumferentially into a plurality of parts. As shown in Fig. IB, the modular spacer may be provided as a single part, which may be ring shaped.
  • the sleeve 18 includes an upper portion 30, which may be seated in a radial groove 34 defined in an upper surface of the supporting member 16.
  • the supporting member 16 includes a uniform upper surface with no radial grooves and the upper portion 30 of the sleeve 18 is seated on the substantially planar upper surface of the supporting member 16.
  • the inwardly-extending radial lip 36 may be provided at an upper surface of the sleeve 18.
  • the sleeve 18 further includes a lower portion 38 generally defined as the portion of the sleeve 18 extending below the upper surface of the supporting member 16.
  • the sleeve 18 is made of substantially uniform material, and thus, the lower portion 38 is sufficiently flexible to permit distortion of the lower portion to achieve non-negligible angles of deflection relative to a non- distorted longitudinal axis thereof.
  • a non-negligible angle of deflection may be ten degrees or more of deflection of one end of the sleeve 18 relative to an opposing end of the sleeve.
  • the sleeve 18 may be formed of various materials to permit non-negligible flexibility.
  • the sleeve 18 may be formed of materials having a hardness ranging from 35 shore A to 90 shore A, or from 35 shore A to 65 shore A, or more specifically about 50 shore A. As can be appreciated, the uniform nature of the sleeve 18 leads to a reduction in manufacturing costs and the likelihood of error during installation. In some embodiments the hardness of the sleeve 18 is less than the hardness of the supporting member 16. Also, the sleeve 18 may be of any suitable length. In one example, the sleeve 18 is 3-4 inches in length.
  • the sleeve 18 further includes one or more sealing elements 44 extending annularly about the sleeve.
  • the sealing elements 44 form a portion of the sleeve 18, and therefore, constitute a region of increased diameter relative to other regions of the sleeve.
  • the sealing element 44 may have a maximum diameter at its upper longitudinal end and generally decrease in diameter to its lower longitudinal end distal from the supporting member 16. In this manner, the sealing element 44 provides a tight water seal with a larger longitudinal coverage than other sealing structures. It is contemplated that the sealing elements 44 may take other shapes so long as they seal the interface between the sleeve 18 and a waste drainpipe or waste flange.
  • the sealing elements 44 may be modified to have a substantially uniform diameter, an increasing diameter from the lower longitudinal end to the upper longitudinal end of the sealing elements, or a varying diameter between longitudinal ends of the sealing elements.
  • the seal apparatus 10 is shown disposed between the plumbing fixture discharge 12 and the waste flange 15.
  • the waste flange 15 is provided as an inner flange disposed on the inside of the waste drainpipe outlet 14.
  • the plumbing fixture discharge 12 may be seated against the sleeve 18 such that an extended portion 42 of the plumbing discharge comes into contact with inwardly- extending lip 36, thereby deflecting the lip downwardly relative to the upper surface 24 of the supporting member 16.
  • the seal apparatus 10 may be disposed against the waste drainpipe outlet 14 and the waste flange 15 is provided as an outer flange disposed on an outside of the waste drainpipe 14.
  • the seal apparatus 10 may be disposed against the waste drainpipe outlet 14 and no waste flange is needed.
  • the flexible seal apparatus 10 has additional benefits, such as the ability to deform to fit undersized pipes.
  • the sleeve 18 may have a substantially circular cross section when not subjected to external forces. Such a configuration is desirable to accommodate connection to a circular- shaped waste flange 15 or waste drainpipe 14.
  • the sleeve 18 may accommodate connection to a variety of drainpipes of non-standardized schedules and to plastic or cast-iron drainpipes.
  • the sleeve 18 may accommodate connection to waste drainpipes having varying sizes.
  • the sleeve 18 can be implemented in waste drainpipes having 3 inch (7.5 cm) and 4 inch (10 cm) diameters because of the flexibility of the sleeve.
  • the flexible sleeve 18 can be implemented into either 3 inch or 4 inch drainpipes when utilizing an appropriately- sized seal, such as the seal 44.
  • the inward lip 36 may deflect downwardly beyond the upper surface 24 of the supporting member 16 when in contact with the plumbing discharge 12.
  • the lip 36 provides a tight seal that will prevent gas and fluids from leaking from the interconnection between the plumbing discharge 12 and the waste flange 15 and the seal is sufficient to not break even if the toilet becomes backed up.
  • the sealing protection provided by the lip 36 eliminates the need for separate additional elements, such as regular wax seals or foam rubber gaskets.
  • the sealing element 44 provides a tight seal between the sleeve 18 and the drainpipe 14, thereby preventing fluid and gases from traveling back up the sides of the sleeve when installed.
  • the seal apparatus 10 may be seated against a surface disposed between a plumbing fixture discharge and a waste drainpipe, such as a floor surface.
  • the sleeve 18 is flexible enough to permit installation between offset, misaligned, angled, or otherwise incongruous plumbing fixture discharges and waste drainpipe outlets.
  • the seal apparatus 10 may be used to connect a plumbing fixture discharge, such as the distal portion of a toilet, to a waste drainpipe, such as a sewage line. In facilitating this connection, the seal apparatus 10 provides a tight seal and reliable connection to prevent any undue leakage or other undesirable consequence of the connection.
  • the waste flange 15 may be installed connecting to a ground slab 50, which may be any type of structural flooring such as a concrete slab or wood decking.
  • the connection may be secured by disposing a plurality of connectors through a plurality of apertures in the waste flange 15.
  • a finished flooring 52 may be thicker than the waste flange 15 into which the seal apparatus 10 is to be installed.
  • An upper surface of the waste flange 15 may be positioned below the surface of the finished flooring 52 when the waste flange 15 is positioned directly on the ground slab 50.
  • the upper surface of the waste flange 15 is vertically offset from the surface of the finished flooring 52 by an offset distance 54.
  • An approach to compensate for the offset distance 54 is to install one or more wax rings stacked together or a standard wax ring combined with an extension ring.
  • preparing such a wax ring assembly is an inconvenient task for the installer, and more importantly, the addition of the wax ring parts to the installation introduces additional sources of leaks.
  • the exemplary seal apparatus 10 shown in Figures 2 and 3 allows the upper surface 24 of the supporting member 16 to be raised close to or above the surface of the finished flooring 52, which is installed on top of the ground slab 50.
  • the seal apparatus may include at least one modular spacer 17 that couples to the lower surface 26 of the supporting member 16 and raises the seal apparatus 10 so that the upper surface 24 of the supporting member 16 is close to or above the surface of the finished flooring 52. By raising the supporting member 16, the ease of installation may be improved.
  • the desired height of the plurality of modular spacers 17 may be substantially equal to the thickness of the finished flooring 52 when the modular spacer 17 is placed on the ground slab 50 or a height difference between the upper surface of the waste flange 15 and the surface of the finished flooring 52 when the spacer 17 is placed on the waste flange 15.
  • the modular spacer 17 may be seated directly on the ground slab 50 or the waste flange 15 and disposed beneath the lower surface of the supporting member 16.
  • the modular spacer 17 may include at least one projection operable to be received in a recessed area defined in the supporting member 16.
  • the modular spacer 17 may not include an projection, but may be shaped to fit in an recessed area defined in the lower surface of the supporting member 16.
  • the lower surface of the supporting member 16 may simply rest on top of the modular spacer 17 without mechanical couplings.
  • the seal apparatus 10 Due to the flexibility of the seal apparatus 10, it may be connected to many types of piping, such as piping made of cast iron, PVC, or ABS. It is to be appreciated that the use of the disclosed seal apparatus 10 together with the modular spacer of the present application allows for unexpected, synergistic results during the installation of the seal apparatus 10. Government regulations often require water or air tests to ensure the absence of any leakage in the waste drainpipe. Conducting such tests, however, sometimes requires a flange apparatus to be installed over the waste drainpipe and sealed either by an integral sealing element or an external plug. The installation of a conventional flange apparatus may involve cementing or laminating one end of the conventional flange apparatus to the waste drainpipe.
  • the seal apparatus 10 allows for the freedom to adjust for height after the finished flooring is laid down after the water or air test. It is to be appreciated that such height adjustments are effected without the use of wax rings, thereby eliminating additional sources of leaks and improving the ease of installation.
  • the seal apparatus 10 includes a plurality of modular spacers 17 that are stackable with each other.
  • the finished flooring 52 is thicker than the finished flooring 52 shown in Figure 3. Therefore, the supporting member 16 needs to be raised higher above the ground slab 50.
  • the plurality of modular spacers 17 may be stackable with each other to raise the supporting member 16 above the finish flooring surface 52 for receiving a discharge end of a plumbing fixture.
  • Figure 4A may be substantially equal to the thickness of the finished flooring 52. If the thickness of the finished flooring 52 is greater than the height of a first modular spacer 17a, the first modular spacer 17a may be placed directly on the ground slab 50 or the waste flange 15 and then a second modular spacer 17b may be placed on top of the first modular spacer 17a. The second modular spacer 17b may then engage with the lower surface 26 of the supporting member 16 and raise the upper surface 24 of the supporting member 16 above the surface of the finished flooring 52.
  • the height of the plurality of stacked modular spacers 17 in Figure 4A is substantially equal to the thickness of the finished flooring 52 when the modular spacer 17a is placed on the ground slab 50 or a height difference between the upper surface of the waste flange 15 and the surface of the finished flooring 52 when the spacer 17a is placed on the waste flange 15.
  • the finished flooring 52 is thinner than the finished flooring 52 shown in Figure 3. Therefore, the modular spacer 17 is not needed and the supporting member 16 may be placed on the waste flange 15.
