Definitions
- the present invention relates generally to the field of gaskets positioned between the toilet base and toilet flange.
- the standard gasket is produced from pliable wax. If the toilet has to be removed for repair, the plumber must manually remove and scrape off the wax gasket prior to installation of a new gasket. Further, the gasket is difficult to observe when the toilet is positioned upon the floor drain providing for the possibility that the gasket will not be aligned with respect to the toilet base and the flange on the floor drain. What is needed is a gasket that exhibits flexibility while maintaining a seal even if the toilet is rocked relative to the floor and which also minimizes degradation of the gasket in the event the gasket is stored or used in a relatively high temperature environment. Further, it is desirable to have a gasket that is repositionable and reusable in the event the toilet must be removed from the floor and reinstalled.

Description
- 1. Field of the Invention
- The present invention relates generally to the field of gaskets positioned between the toilet base and toilet flange.
- 2. Description of the Prior Art
- A gasket is positioned between the outlet base of a toilet and the upwardly facing toilet flange provided on the floor drain. The object of the gasket is to provide a water and gas seal; however, many of the prior art gaskets develop leaks. Frequently a gasket is stored in a high temperature environment prior to installation of the gasket thereby causing the gasket to degrade. In the event the gasket is subjected to high temperatures or if the toilet is rocked back and forth then leaks may develop.
- The standard gasket is produced from pliable wax. If the toilet has to be removed for repair, the plumber must manually remove and scrape off the wax gasket prior to installation of a new gasket. Further, the gasket is difficult to observe when the toilet is positioned upon the floor drain providing for the possibility that the gasket will not be aligned with respect to the toilet base and the flange on the floor drain. What is needed is a gasket that exhibits flexibility while maintaining a seal even if the toilet is rocked relative to the floor and which also minimizes degradation of the gasket in the event the gasket is stored or used in a relatively high temperature environment. Further, it is desirable to have a gasket that is repositionable and reusable in the event the toilet must be removed from the floor and reinstalled.
- Currently there are a number of solutions for a toilet flange gasket. Some of these solutions use a wax ring, but these solutions fail to meet the need of the industry because the wax is not resilient. Other solutions attempt to use open cell foam encased in wax. This is similarly unable to meet the industry needs. Still other solutions attempt to use a pvc extension which is glued to the bottom of the toilet around the horn. While this solution is wax-less, there are multiple flange outlet sizes that need to be known to match the proper gasket to the flange, also it will not stick well to the bottom of a toilet that has been previously positioned on a wax ring. Therefore, its suitability is primarily limited to use on new toilet installation and not easily used in repositioning an existing toilet.
- A number of U.S. patents have been granted on toilet gaskets. U.S. Pat. No. 6,694,537 issued to Telles discloses a polyethylene foam gasket having resilience and the ability to recover substantially its original shape and thickness after compression loading. The U.S. Pat. No. 6,691,331 issued to Telles discloses an elastomeric gasket located between the toilet bowl and the floor. The U.S. Pat. No. 3,821,820 issued to Thompson discloses a toilet gasket having a ring of wax-like material. The U.S. Pat. No. 4,482,161 issued to Izzi, discloses a toilet gasket designed to replace the conventionally used wax sealing rings and having a main body of rubber like material, such as polyvinyl chloride. The U.S. Patent Publication 2006/0225195 discloses an anti-microbial package for use in toilet wax gaskets. U.S. Pat. No. 5,114,980 issued to Lii et al. discloses a polyurethane integral skin foam for use in producing various products.
- The present invention is superior when compared to other known devices and solutions because the present invention provides a suitable seal without the use of wax. Furthermore, the present invention is repositionable, can be used over a wide temperature range, provides a seal on various flange configurations relative to floor grade and is antimicrobial. In addition, the present invention can be stacked to provide a seal when the gap is too large for one gasket. For additional protection, the gaskets can be siliconed together or coated with plumbers grease. The present invention is unique in that it is structurally different from other known devices and solutions. More specifically, the present invention is unique due to being made of integral skin polyurethane foam.
- A wax-less, repositionable gasket provides a liquid and gas seal between a toilet base and a toilet flange that is provided on a drain conduit to which the toilet base is mountable. The gasket has a main body of polyurethane foam construction that extends throughout the main body. It has a ring shaped upper portion for acting as a seal between a toilet base and a toilet flange on a drain conduit and a truncated conical extension integral with the ring shape. The extension is positioned into the drain conduit to direct liquid flow. The main body has an outer skin integral therewith providing structural stability to the construction maintaining a seal despite varying loads thereon by the toilet base and despite repositioning thereof.
- It is an object of the present invention to provide a new and improved gasket for positioning between a toilet base and flange of a floor drain.
- A further object of the present invention is to provide a wax-less repositionable toilet gasket.
- In addition, it is an object of the present invention to provide a wax-less toilet gasket having a main body with an outer skin insuring structural integrity.
- Related objects and advantages of the present invention will be apparent from the following description.

FIG. 3 is a cross-sectional view taken along the line 3-3 ofFIG. 2 and viewed in the direction of the arrows. -
FIG. 4 is a side view of a pair ofidentical gaskets - For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
- Referring now more particularly to the drawings, there is shown a wax-less repositionable
toilet flange gasket 15 positioned between atoilet flange 16 attached to thefloor drain conduit 17 and thetoilet base 18, in turn, attached to the toilet. -
Gasket 15 includes amain body 19 of polyurethane foam construction which extends throughout the main body.Main body 19 includes a ring shapedupper portion 20 integrally attached to a truncatedconical extension 21 that is extendable into thetoilet flange 16, in turn, extended into and fixedly attached to thedrain conduit 17.Extension 21 directs liquid flow intotoilet flange 16 andconduit 17. - Ring shaped upper portion includes a outer top
curved surface 22 extending downwardly to avertical surface 23 with bothsurfaces longitudinal center axis 24.Upper portion 20 forms ahollow interior 25 receiving the fluid from the downwardly extendingextension 26 oftoilet base 18.Base extension 26 fits intohollow interior 25 that is formed by a top innercurved surface 27 that extends downwardly to aplanar surface 29 extending through the length ofextension 21.Planar surface 29 andcurved surface 27 extend continuously aroundaxis 24. The junction of the outercurved surface 22 and the innercurved surface 27 forms an upwardly facingtop surface 28 that contacts the downwardly facingflat surface 30 offlange 31 oftoilet base 18 effecting a liquid and gas tight seal betweentoilet base 18 andgasket 15. The gasket, toilet base and toilet flange are shown in separated positions in the drawings in order to more clearly show the various components; however, it is to be understood that in use,base 18 is in contact withgasket 15 which, in turn, is in contact withtoilet flange 16. - A downwardly facing flat or
planar surface 33 extends continuously aroundextension 21 being joined at its outer edge portion to surface 23 and on its inner edge portion toextension 21.Extension 21 is a truncated, downwardly extending, cone forming a hollow passage through which the liquid and gas flow.Extension 21 has an outsidecontinuous surface 34 parallel to the inner continuousflat surface 29. The outside diameter of the extension formed bysurface 34 along with the inside diameter of the extension formed bysurface 29 both decrease in diameter as the extension extends downwardly.Surface 29 is blended into innercurved surface 27 whereas the outsidecontinuous surface 34 is at an oblique angle toplanar surface 33. - Building floor 40 may include a bottom
wood floor frame 41 having positioned thereon afinished floor 42 of suitable material, such as tile.Toilet flange 16 has a continuous ring shapedflange 43 integrally joined to acylindrical pipe extension 44, in turn, extending intodrain conduit 17.Extension 44 is sealed toconduit 17 by any number of conventional means. Floor 40 includes a hole through whichextension 44 extends withflange 43 then being positioned atop floor 40 or in some cases being recessed into the floor. - A pair of
conventional bolts heads 48 extended intoholes 49 provided 180 degrees apart onflange 16 with onesuch hole 49 being shown inFIG. 1 . A pair of accurate shaped slots extend from eachhole 49 with each slot having a counter bore or enlargedlower opening 50 enabling thehead 48 of each bolt to be extended throughopenings 49 while the shank of the bolt is extended upwardly. The shanks may be moved along the lengths of the accurate slots to distance the bolt head apart fromhole 49 preventing accidental disengagement of the bolt from the flange. Each bolt shank then extends through bolt holes 52 and 53 located 180 degrees apart on the upper portion of the gasket.Holes curved surface 22 and the downwardly facingplanar surface 33 of the ring shaped configuration. Outercurved surface 22 is positioned radially outward ofextension 21. - Once the gasket is installed to the toilet flange by the extending
extension 21 intoextension 44 and with the bolt shanks passing throughholes toilet base 18 is mounted to the bolts.Toilet base 18 includes a pair of bolt holes 56 and 57 located 180 degrees apart with the bolt shanks then extending aboveflange 31 whereat conventional hexagonally shaped nuts 59 (FIG. 1 ) are threadedly mounted to the bolt shanks thereby forcingtoilet base 31 ontogasket 15 and, in turn, the gasket ontotoilet flange 16 compressing the gasket and providing the liquid and gas seal between the toilet andconduit 17. Planar surface 33 contacts the upwardly facing surface offlange 43 affecting a liquid and gas seal between the gasket and thetoilet flange 16. - The truncated conical shaped
extension 21 ofgasket 15 is particularly useful in allowing gaskets to be stacked together. For example, top gasket 70 (FIG. 4 ) includes anextension 71 extending down through the ring shaped upper portion and intoextension 73 oflower gasket 72. In the event the distance betweentoilet base 18 andtoilet flange 16 is greater than the height 80 (FIG. 2 ), then a pair ofgaskets 70 and 72 (FIG. 4 ) identical to gasket 15 may be stacked together. In such a case, thetop surface 28 seals againsttoilet base 18 whereas the bottomplanar surface 33 oftop gasket 70 seals against thetop surface 28 ofbottom gasket 72 and the bottomplanar surface 33 ofbottom gasket 72 seals againsttoilet flange 16 in a manner identical to that described forgasket 15. - The combination shown in the drawing consisting of the toilet base, drain conduit, building floor and gasket is particularly advantageous to accommodate variations and positioning of the
flange 43 oftoilet flange 16. That is,flange 43 may be positioned completely on top of theupper floor layer 42 or may be recessed as shown inFIG. 3 with the top surface of thetoilet flange 16 being located slightly above the top surface offloor layer 42. Likewise, the top surface offlange 43 may be positioned beneath the top surface offloor layer 42 while still allowing the gasket to ensure a tight seal between the toilet base and toilet flange. This is true since the thickness of the ring shaped main body is sufficient to allow for variations in the positioning oftoilet flange 16. In one embodiment, the thickness 80 (FIG. 2 ) has a thickness of at least one inch to accommodate variations and positioning of the toilet base relative to the upper surface offloor layer 42. By ensuring thatdimension 80 is at least one inch between thetop surface 28 andplanar surface 33, the seal is accomplished withtoilet flange 43 regardless of variations and positioning of thetoilet flange 43 relative to thebuilding floor 42 even throughflange 43 is above or below the top surface offloor layer 42 providing the distance betweenbottom surface 30 oftoilet base 18 andtoilet flange 16 is not greater than one inch. -
Gasket 15 is composed throughout of a self skinning polyurethane foam (polyurethane integral skin foam). Integral skin foam is flexible on the inside but tough on the outside. It has been used for athletic equipment and office seating applications. Such a product is available from Renosol of Saline, Minn. 48176. The material is also available from Jones & Vining, Inc. of Brockton, Mass. The polyurethane may be composed of the reaction product of a polyether polyol blend and an isocyanate. The polyol blend consists of a combination of polyether polyols (polyhydroxyl or polyamine compounds), surfactants, chain extenders, catalysts and any single or combination of physical and/or chemical blowing agents. The isocyanate may be either an MDI (diphenylethane diisocanate) or TDI (toluene diisocynate) or any combination thereof. The molded density of the product skin should be between 0.04 and 0.40 gm/cc. The product will perform over a temperature range of 0 to 200 degrees Fahrenheit. One integral skin foam is available under the name Poly 900 IS/Bayflex 976 A Iso from BayOne Urethane Systems LLC, St. Louis Mo. with parts typically molded to a density of 14-20 pcf. The polyurethane integral foam may be polyether based having BHT (butylated hydroxyl-toluene) providing an anti-microbial construction for the gasket. - While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected. For example, plumbers grease may be applied to the top surface of the gasket
main body 19 and/or thebottom surface 33 of the gasket main body to achieve a superior seal.
