Description

UNIVERSAL HEIGHT ABSORBING TOILET SEAL
TECHNICAL FIELD
[01] The present disclosure relates generally to a seal for connecting conduits, such as plumbing fixtures, to waste drain conduits, such as waste drainpipes.
More particularly, the present disclosure is related to a universal height absorbing toilet seal that provides a sealed interconnection between a toilet and a toilet flange.
Related methods for interconnecting conduits are also described.
BACKGROUND

[02] 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 must be connected to the waste drainpipe by fluid carrying conduits. Typically, the toilet bowl will sit flat on a finished flooring surface and will interface with a toilet flange that is connected to the waste drainpipe.

[03] However, there are many variables associated with the toilet installation process that may or may not lead to a proper seal between the toilet and the toilet flange. The toilet flange may interconnect with the waste drainpipe by either fitting inside or outside the waste drainpipe, and the toilet flange may have a variety of diameters, such as a diameter of 3 inches or 4 inches. Thus, there are four, or more, different types of toilet flanges that may be used, each of which requires its own installation considerations.

[04] In addition to the four different types of toilet flanges, there are additional installation variables related to height differences between the surface of the toilet flange and the finished flooring surface. The toilet flange may rest on top of the finished flooring surface, may be flush with the finished flooring surface, or may sit below the finished flooring surface. Each toilet bowl may also have a different toilet lip height that may require different installation techniques to create a desirable seal between the toilet and the toilet flange.
105] As a result, because of the different heights of toilet flanges, floor levels, and toilet lips, wax seals and/or modification of the waste drainpipes are typically needed to create a desirable seal between the toilet and the toilet flange.
The wax seals are typically a uniform thickness and proper sealing often requires multiple wax seals in order to create a seal between the toilet and the toilet flange. However, the wax seals do not provide sufficient feedback to an installer during installation and once the toilet is placed over the toilet flange, the installer cannot see if a proper seal has been formed and is forced to rely only on tactile feel to determine if there is a proper seal. Without compression of the wax seals, it can be difficult to determine if a proper seal has been created. These wax seals are also not reliable because the seal connection is not strong enough to prevent leakage and associated odors, and oftentimes they can be expensive and inefficient due to delays in the installation process. Further, once the wax seals are set, they may not be able to be reset in a new position.

[06] Therefore, an improved sealing system for addressing the above-described problems are desired. Related methods for installing a seal between the toilet and the toilet flange are also desired, BRIEF SUMMARY
[071 Disclosed herein is an exemplary embodiment of a universal height absorbing toilet seal flange system for providing a desirable seal between a toilet and a toilet flange as well as a conduit between a plumbing fixture discharge and a waste drainpipe outlet. The system may comprise a flexible sleeve, a compression member, one or more compressible spacers, and/or one or more spacers.

DETAILED DESCRIPTION
[41] Various aspects of a universal height absorbing toilet seal and related methods for installing a universal height absorbing toilet seal between a toilet = and a toilet flange according to the present disclosure are described. It is to be understood, however, that the following explanation is merely exemplary in describing the devices and methods of the present disclosure. Accordingly, any number of reasonable and foreseeable modifications, changes, and/or substitutions are contemplated without departing from the spirit and scope of the present disclosure.
[42] Referring to Figures 1-5, a universal height absorbing toilet seal 10 according to the present disclosure includes a flexible sleeve 12 depending downwardly from a flange member 14, and a compressible member 16 disposed underneath the flange member. As shown in Figure 2, in some embodiments, the flexible sleeve may have a cylindrical shape. However, in other embodiments, such as the embodiment depicted in Figure 19A, the flexible sleeve 12 may taper from an upper portion of the flexible sleeve to a lower portion of the flexible sleeve such that the upper end of the sleeve has a diameter that is larger than a diameter of the lower end of the sleeve. In this latter embodiment, the tapered or conical shape of the flexible sleeve 12 facilitates insertion of the flexible sleeve into a waste drainpipe outlet. The tapered shape of the flexible sleeve 12 in Figure 19A further permits stacking of two or more toilet seals 10, which saves space, as shown in Figure 19B. One or more compressible spacers and/or one or more spacers may optionally be provided with the seal 10 as will be described.

In some embodiments, the height absorbing seal 10 is made from a flexible material, such as rubber, foam or polyvinyl chloride (commonly referred to as "PVC").
[43] The flange member 14 includes an upper surface 22 that may comprise one or more seals 24 and an inwardly extending flexible lip 26 that surrounds an aperture 28 defined through the seal 10. In embodiments where multiple seals 24 are disposed along the upper surface 22 of the seal 10, the seals may be disposed concentrically relative to one another. The concentric seals 24 may comprise ring-shaped ridges that extend from the upper surface 22 of the seal 10. The one or more concentric seals 24 are operable to create a seal against a bottom surface of the toilet when the toilet is installed over the universal height absorbing toilet seal 10. In one embodiment, the universal height absorbing toilet seal 10 may comprise three concentric seals 24. Of course, the seals 24 may be provided in any number of ways.
Figure 28 illustrates an example where the seals 24 have a geometric pattern.
The seals 24 may also have a flared outermost rib (Figs. 29A, 30A), triangular ribs (Figs. 29B, 30B), dome shaped ribs (Figs. 29C, 30C), or square/rectangular ribs (Figs.
29D, 30D), with (Figs. 29A, 29B, 29C and 29D) or without (Figs. 30A, 308, 30C and 30D) bosses (discussed in more detail below),In some embodiments, the flared outermost rib (Figs.
29A, 30A) may have a greater height relative to the other ribs.
[44] The height absorbing seal 10 may further comprise one or more optional tabs 30 extending from the upper surface 22 that include setting holes 32 defined therethrough. The setting holes 32 may receive fasteners for securing the universal height absorbing toilet seal between the toilet and the toilet flange and waste drainpipe outlet. In one embodiment, two tabs may be provided that are spaced 180 apart from each other about an outer circumference of the height absorbing seal 10. Also, as depicted in the embodiment of Figures 20A and 20B, bosses 33 may be formed around the setting holes 32 to facilitate holding the fasteners in a generally vertical position to aid alignment of the fasteners with holes of the fixture. Figure 26 illustrates the setting holes 32 facilitating the vertical orientation of the fasteners 35, which extend upwardly from the toilet flange 50. With reference to Figures 27A and 27B, setting holes 32 may also be tapered (e.g., an inner diameter taper) respectively in an upward or downward direction to facilitate insertion and/or retention of the fasteners.
1451 The flexible sleeve 12 may accommodate varying diameters of waste drainpipe outlets and/or toilet flanges. In one embodiment, a diameter of the inner aperture 28 at the upper surface 22 may be substantially equal to or slightly larger than a diameter of the flexible sleeve, thus defining a conduit for waste to flow from the plumbing fixture discharge, through the universal height absorbing toilet seal 10 and toilet flange, and into the waste drainpipe outlet.
[46] Referring to Figure 2, the height absorbing seal 10 includes a lower surface 40, which is defined opposite the upper surface 22. The upper surface terminates at an outer circumference of the height absorbing seal 10. The height absorbing seal 10 further includes a downwardly depending annular portion 42, which is substantially orthogonal to the upper surface 22. However, in some embodiments such as that depicted in Figure 21, the annular portion 42 may be flared outward to allow flexure or bending outwards when the toilet seal 10 is compressed. This ensures the sealing surface of the compressible member 16 is not compromised. Also, while depicted as being substantially coextensive with the compressible member 16 in Figures 4-5, in some embodiments such as that depicted in Figure 22, the annular portion 42 may be shorter in length than the compressible member 16 such that the annular portion 42 flexes outward when the toilet seal 10 is compressed, thus accomplishing a similar function to that of the embodiment in Figure 21. In still further embodiments, the seal may not have a downwardly depending annular portion. The height absorbing seal 10 further includes a radiused wall 44, which extends from the lower surface 40 to the flexible sleeve 12. The diameter of the wall 44 is radiused from a larger diameter proximate to the lower surface 40 to a smaller diameter proximate to the flexible sleeve 12. The lower surface 40, annular portion 42 and radiused wall 44 cooperate to define a cavity 46. The cavity 46 may receive the compressible member 16 (Figures 3-4).
In embodiments with no annular portion, the lower surface 40 and radiused wall 44 cooperate to define the cavity 46.
[471 Referring to Figs. 3-5, the universal height absorbing toilet seal 10 may further comprise the compressible member 16. The compressible member 16 may comprise an internal aperture 48 defined therethrough operable to receive the flexible sleeve 12 and may be sized and shaped to be received within the cavity 46 defined in height absorbing seal 10. The compressible member 16 may be made from foam or a similar material and may be permanently affixed to the lower surface 40 of the seal 10 within the cavity 46 or may be removably connected to the seal 10. The compressible member 16 may be operable to be compressed between the height absorbing seal 10 and a top surface of a toilet flange 50 inserted into a waste drainpipe 51 (see, e.g., Figure 13).

[481 Referring to Fig. 6, the universal height absorbing toilet seal 10 may further comprise one or more modular spacers 52. In some embodiments, the spacers 52 are rigid and may be modified to include a pair of tabs 54 defining setting holes 56 (Fig. 7) for receiving securing fasteners (not shown). In such embodiments, the tabs 54 may be situated 180 from each other about an outer circumference of the spacer 52 and may be operable to align with the one or more tabs 30 of the height absorbing seal 10.
The spacer 52 may be formed of a variety of materials, such as rigid plastic or metal.
However, in some embodiments, the spacer 52 may be formed of a pliable or flexible material.
[49] The one or more spacers 52 may be used to raise the upper surface 22 of the height absorbing seal 10 relative to the toilet flange 50 and is operable to interact with and create a seal with the compressible member 16. In some embodiments, the spacer(s) 52 may be disposed above the seal 10 to itself accommodate a difference in height between the seal and the toilet flange 50. Like the compressible member 16, the one or more spacers 52 may include an inner aperture defined therethrough for receiving the flexible sleeve 12. In one embodiment, the spacer 52 may comprise one or more concentric seals 58 that may take the form of ring-shaped ridges that extend from an upper surface of the spacer 52 and may be located proximate to and centered about the inner aperture. The concentric seals 58 are operable to create a seal against a bottom surface of the compressible member 16. In one embodiment, the spacer 52 may comprise three concentric seals 58.
[50] In some embodiments, in addition to the concentric seals 58 formed on the upper surface of the spacer 52, the spacer may further comprise concentric seals formed on a lower surface of the spacer such as depicted in Figure 23. In still further embodiments such as that depicted in Figure 24, the spacer may only have concentric seals 58 formed on a lower surface thereof. The compressible member 16 may also have concentric ridges 59 formed in an upper and/or lower surface thereof as shown in Figure 25. While the concentric seals 58, 59 disclosed herein are radiused in profile, alternative ridge profiles are contemplated to fall within the scope of the present disclosure. See, for example, Figures 28-30.
[51] The universal height absorbing toilet seal 10 may further comprise one or more modular compressible spacers 60 that are positionable above or below the spacer 52. Similar to the one or more spacers 52, the one or more compressible spacers 60 may also be used to raise the upper surface 22 of the height absorbing toilet seal 10 relative to the toilet flange 50. In some embodiments, the modular compressible spacers 60 are of similar construct (e.g., made of foam) to the compressible member 16 disposed within the cavity 46. Each modular compressible spacer 60 may be operable to interact with and create a seal with the rigid spacer 52, the toilet flange 50, and/or another compressible spacer. Each compressible spacer may similarly comprise an inner aperture 62 defined therethrough for receiving the flexible sleeve 12.
[52] The compressible spacer 60 may further comprise one or more tabs 64 with optional setting holes 66 that are operable to receive securing fasteners (not shown). In one embodiment, the compressible spacer 60 may include two tabs situated 180 from each other about an outer circumference of the compressible spacer and may be operable to align with the two tabs 30 of the height absorbing toilet seal 10 and the two tabs 54 of the rigid spacer 52.

[53] Referring to Fig. 9, one spacer 52 may be affixed to one modular compressible spacer 60 in order to create a modular spacer 70, which may be used to raise the upper surface 22 of the height absorbing toilet seal 10 relative to the toilet flange 50. In the embodiment depicted in Fig. 9, the spacer 52 may not have tabs while the compressible spacer 60 may have tabs 64; however various combinations of tabs on the rigid spacer and the compressible spacer are contemplated.
[54] Accordingly, in some embodiments, and with reference to Figures 10-12, the height absorbing toilet seal 10 may include the flexible sleeve 12, the flange member 14 and the compressible member 16 in combination with the spacer 52 ancUor the modular compressible spacer 60. The embodiment of Figure 10 illustrates the compressible member 60 having tabs 64, while the embodiment of Figure 11 illustrates the spacer having tabs 54. Of course, other embodiments are contemplated in which each of the spacer 52 and compressible member 60 have tabs and in which no tabs are provided. Also, additional spacers 52 and compressible members 60 may be provided depending on the height adjustment desired.
[55] Referring to Figures 13-17, in operation, the toilet flange 50 may be inserted into the waste drainpipe outlet 51 in such an arrangement where an upper portion 80 of the toilet flange may be higher than, level with, or lower than a finished flooring surface 82. Typically, the waste drainpipe outlet 51 does not extend above a subflooring region 84. Accordingly, the height absorbing toilet seal 10 may be used to create a sealed conduit in conjunction with the waste drainpipe outlet 51 and thus a desirable seal between a toilet 86 and the toilet flange 50.

[56] In some embodiments, such as the one depicted in Figures 13-14, the height absorbing seal 10 may be used without rigid or modular spacers 52, 60.
For example, in some scenarios, the toilet flange 50 will be disposed above the finished flooring surface 82. The height absorbing seal 10 may be disposed into the toilet flange 50 such that the flexible sleeve 12 extends in a downward direction into the toilet flange. The flange member 14 and compressible member 16 of the height absorbing toilet seal 10 may thus rest on an upper surface of the toilet flange 50.
During installation, a horn section 92 of the toilet 86 may then be inserted into the height absorbing seal 10 such that it comes into contact with the inwardly extending flexible lip 26. As a result, the flexible lip 26 flexes downward when it comes in engagement with the toilet horn 92 and the flange member 14 and compressible member 16 are compressed in engagement with the toilet flange 50, thus providing a desirable seal.
Further, the concentric seals 24 disposed along the upper surface 22 of the flange member 14 of the height absorbing seal 10 come into sealed engagement with a lower surface of the toilet 86.
[57] Referring to Figure 15, the height absorbing seal 10 may be modified to include a rigid spacer 52 to accommodate for an increased height between the lower surface of toilet 86 and the toilet flange 50. This increased height may be due to a toilet having an increased size along a lower portion thereof, the toilet flange being disposed flush with the finished flooring or combinations of such factors. In practice, the horn section 92 of the toilet 86 may be inserted into the height absorbing seal 10 such that it comes into contact with the inwardly extending flexible lip 26. As a result, the flexible lip 26 flexes downward when it comes in engagement with the toilet horn 92 and the flange member 14 and compressible member 16 are compressed in engagement with the rigid spacer 52, which is disposed between the compressible member 16 and the toilet flange 50, thus providing a desirable seal. Further, the concentric seals 24 disposed along the upper surface 22 of the flange member 14 of the height absorbing seal 10 come into sealed engagement with a lower surface of the toilet 86. The concentric seals 58 of the rigid spacer 52 also seal into the compressible member 16 further strengthening the seal.
[58] In further embodiments, and with reference to Figures 16-17, the height absorbing seal 10 may be further modified to include both a rigid spacer 52 and a modular compressible member 60 to accommodate for situations where there is an increased distance between the lower surface of the toilet 86 and the toilet flange 50.
For example, the toilet flange 50 may be disposed against the subflooring region 84, while the toilet 86 rests against the finished flooring surface 82. In such arrangements, the height absorbing toilet seal may be modified to include both a rigid spacer 52 and a modular compressible member 60 to accommodate for the increased height between the lower surface of toilet 86 and the toilet flange 50. In some embodiments, the rigid spacer 52 may be coupled to the modular compressible member 60 to form a unitary rigid spacer/modular compressible member combination.
[59] In practice, the horn section 92 of the toilet 86 may be inserted into the height absorbing seal 10 such that it comes into contact with the inwardly extending flexible lip 26. As a result, the flexible lip 26 flexes downward when it comes in engagement with the toilet horn 92 and the flange member 14 and compressible member 16 are compressed in engagement with the rigid spacer 52 and the modular compressible member 60. The modular compressible member 60 is also compressed against the upper surface of the toilet flange, thus providing a desirable seal. Further, the concentric seals 24 disposed along the upper surface 22 of the flange member 14 of the height absorbing seal 10 come into sealed engagement with a lower surface of the toilet 86. The concentric seals 58 of the rigid spacer 52 also seal into the compressible member 16 further strengthening the seal.
[60] Referring to Figure 18, in yet another embodiment, the height absorbing seal 10 may be modified to exclude the rigid spacer 52, yet include a modular compressible member 60. The height absorbing seal 10 of Figure 18 thus provides a desired seal by sealing the concentric seals 24 against the lower surface of the toilet 86 and via compression of the compressible members 16, 60 against the upper surface of the toilet flange 50.
[61] It is to be appreciated that installations involving taller toilets, toilet flanges sunk below the finished flooring surface, or taller finished flooring surfaces, one or more rigid spacers 52 and/or modular compressible spacers 60 may be added as needed to raise the level of the universal height absorbing toilet seal 10 relative to the toilet flange 50.
[62] Advantageously, the universal height absorbing toilet seal 10 creates a desirable seal between the toilet 86 and the toilet flange 50 without the need for one or more wax rings. The universal height absorbing toilet seal 10 may be used with any type of toilet flange, all brands and models of toilets regardless of the height of the toilet, and works with toilet flanges sitting flush, above, or below the finished flooring surface. Further, during installation, the universal height absorbing toilet seal 10 can be moved to ensure a desirable seal and can be used more than once. In addition, the compressible nature of the universal height absorbing toilet seal 10 provides tactile feedback to the installer, ensuring that a proper seal has been created even when the toilet has been installed over the universal height absorbing toilet seal and the seal cannot be seen. The universal height absorbing toilet seal 10 also maintains sufficient support below the surface of the flexible sleeve 12 regardless of the number of rigid spacers 52 and/or modular compressible spacers 60 used.
[63] The breadth and scope of the present disclosure should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents. For example, in some embodiments, the height of the seals disclosed herein may be adjusted by providing an additional seal and stacking the additional seal on top of the original seal.
In such embodiments, the additional seal may be of similar construct to the original seal. Also, in some embodiments, the downwardly depending annular portion 42 of the seal 10 may be removed, and thus the compressible member 16 is disposed adjacent to the lower surface 40 of the flange member 14. Moreover, the above advantages and features are provided in described embodiments, but shall not limit the application of the claims to processes and structures accomplishing any or all of the above advantages.
[64] Additionally, the section headings herein are provided as organizational cues.
