Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved toilet sealing ring adapter assembly embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the toilet sealing ring adapter assembly 10 is comprised of a plurality of components. Such components in their broadest context include a sewer pipe 12, a rubber seal 14 and a toilet ring 16. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
More specifically, the toilet sealing ring adapter assembly 10 is adapted for use in association with a conventional toilet. The apparatus includes a sewer pipe 12. The sewer pipe is preferably of a four-inch diameter and is fabricated of any of the conventional materials for sewer pipes such as cast iron ABC, PVC, transit, lead, vitreous clay, etc. The pipe is fabricated in a plurality of different lengths and configurations to accommodate the requirements of different users. In most instances, the pipe will be positioned beneath the floor of a bathroom, with the pipe extending upward from the floor. The sewer pipe has a horizontally oriented open mouth with an upper periphery 20. In the operative orientation, a toilet is coupled to the open mouth of the pipe by use of the toilet sealing ring adapter assembly 10 and a formable elastomeric ring 22. Note FIG. 1.
A rubber seal 14 is formed in a generally cylindrical configuration with a central aperture 24. The outer diameter of the seal is approximately four and one quarter inches. The diameter of the aperture of the seal is approximately three inches. The height of the rubber seal is approximately one and one eighth inches. The rubber seal also has a plurality of internal female screw threads 26. The rubber seal has a smooth outer surface 28. This feature allows the user to place the seal within a pipe even if the internal screw threads of the pipe have been worn. The upper extent of the seal has a circumference and, and the embodiment of FIGS. 1 and 5, includes a lip 30 projecting outwardly from it. The lip allows the rubber seal to sit flush on top of the sewer pipe without falling into the interior of the pipe. The lower extent of the seal is adapted to be positioned within a four-inch cast iron sewer pipe with the lip positioned flush with the upper periphery of the pipe. Note FIGS. 1-3.
A toilet ring 16 is fabricated of cast iron or other suitable material and formed in a generally cylindrical configuration with a central aperture 32. The height of the toilet ring is approximately one and one half inches. In alternative embodiments of the apparatus, the toilet ring is fabricated of ABS plastic or PVC materials. The ring includes an upper region 34 and a lower region 36. The upper region has a larger inner diameter than the lower region with a gradually decreasing diameter therebetween. The diameter of the lower region of the central aperture is approximately two and three quarters inches. In the preferred embodiment, the toilet ring is fabricated of cast iron. The preferred embodiment is utilized for industrial applications. In an alternative embodiment, the toilet ring is fabricated of ABS plastic. This embodiment is utilized for the retail and do-it-yourself markets. Note FIGS. 1, 3 and 5.
The upper region includes a planar circular shaped ledge 38 extending from it. The ledge includes an upper surface 40 and a perimeter 42. The diameter of the ledge is approximately six and fifteen sixteenths inches. In one embodiment of the apparatus, the ledge is fabricated of cast iron. In another embodiment of the apparatus, the ledge is fabricated of an elastomeric substance, such as plastic or rubber. The ring has diametrically opposing closet bolt recesses 44 formed contiguously with the perimeter. Each recess 44 includes a closet bolt 46 extending through it and above the ledge. The closet bolts are adapted to be threadedly coupled to a toilet. The ledge also includes diametrically opposing elongated closet bolt apertures 48 extending therethrough. The apertures 48 permit the positioning of additional closet bolts therethrough. Note FIGS. 1, 2 and 4.
The ledge further includes four equidistantly spaced beveled holes 50 extending therethrough. The bevel holes permit the secure coupling of the ring to the floor of a bathroom or other mounting surface. The present invention can reduce the installation time of a toilet. This is due to the fact that mounting the toilet sealing ring assembly 10 to the interior eliminates the need for time consuming floor sawing around the pipe. Note FIGS. 1, 2 and 4.
The lower region includes a plurality of male external screw threads 52. The lower region is adapted to be threadedly coupled within the rubber seal. In one embodiment of the apparatus, the male external screw threads are fabricated of cast iron. In another embodiment, the male external screw threads are fabricated of an elastomeric substance, such as plastic or rubber. In an operative orientation, the upper surface of the ledge supports a toilet bowl, and the closet bolts secure the toilet bowl in place. Note FIGS. 1 and 4.
Alternate embodiments of the inventions are shown in FIGS. 6, 7 and 8. In the FIG. 6 embodiment, the seal is shown as being formed without the lip to maintain the seal at the upper edge of the sewer pipe. In such alternate embodiment, the lip is removed and the seal is located with its upper edge at the upper edge of the sewer pipe. In such alternate embodiment, there is no extender on the toilet ring as in the following embodiments of FIGS. 7 and 8. In the following embodiment as shown in FIG. 7, a cylindrical extender or spacer is formed between the ledge of the toilet ring and it threads. This allows for the coupling between the toilet ring and the flexible seal to be fully effective in the event that flooring or other material is on the floor surrounding and above the sewer pipe. In such FIG. 7 embodiment, the toilet is located as in the FIG. 6 embodiment but the ledge and toilet thereabove are at a slightly elevated location. In the FIG. 8 embodiment, the spacer or extender is of an extended length to allow for the positioning of the seal to a lower position within the sewer pipe and the toilet ring at a further elevated elevation.
More specifically, in light of the alternate embodiments, the present invention may also be considered as including a toilet sealing ring adapter assembly for use in association with a toilet and a sewer pipe. The toilet sealing ring adapter assembly thus comprises a flexible seal formed of a resilient material in a generally cylindrical configuration with a central aperture forming an upper region and a lower region and also forming an internal surface and an external surface, the external surface having a common diameter along its axial length and adapted to be positioned in contact with an interior surface of a sewer pipe, the interior surface being cone shaped in configuration with screw threads formed therein.
Also included as part of the assembly is a toilet ring formed of an essentially rigid material in a generally cylindrical configuration with a central aperture forming an upper region and a lower region and also forming an internal surface and external surface, the external surface being cone shaped in configuration with external screw threads formed thereon, the upper region including a planar ledge extending therefrom the ledge including a plurality of apertures to permit coupling to a toilet, the threads of the toilet ring being positionable within the threads of the seal whereby upon rotation of the ring with respect to the seal the toilet ring will be pulled into the seal and the seal will be expanded radially for securing the seal and toilet ring in a sewer pipe.
In the FIG. 6 embodiment, the toilet ring 56 is formed as in the primary embodiment. The seal 58 is formed in the primary embodiment except that the lip is removed whereby the upper edge of the seal is flush with the upper edge of the sewer pipe.
In the FIG. 7 embodiment, the toilet ring 62 further includes a cylindrical extender or spacer 64 formed in the toilet ring between the planar ledge and the threads. In such FIG. 7 embodiment, the axial length of the extender is between about 1/4 inch and 3/4 inch. The seal 58 is as in the prior embodiments. In the FIG. 8 embodiment, the extender or spacer 68 has an axial length of about 4 inches, plus or minus 10%. The ring is formed. as in the prior embodiments but is preferably located beneath the upper edge of the sewer pipe. In both embodiments of FIGS. 7 and 8, there is thus provided, by the extender or spacer, a space above the upper edge of the sewer pipe for additional flooring material. The length of the extender may thus be between about 0.25 inches and 4.4 inches as a function of the particular application.
The seal is preferably formed from an essentially resilient material selected from the class of essentially resilient material including an elastomeric material, natural rubber or synthetic, including blends thereof.
The toiler ring is preferably formed of an essentially rigid material selected from the class of essentially rigid materials including cast iron, ABS and PVC.
The threads of the seal and toilet ring in all embodiments are such that a complete coupling between the threads is affected by between about 2.5 and 4.5 rotations of the ring with respect to the seal.
The method of installing the toilet sealing ring adapter assembly as set forth above is afforded, first, by providing the abovementioned components. The user may start installation by separating the seal and the ring by rotating the seal counterclockwise with respect to the ring. This is necessary since the present invention is delivered to a user in an engaged orientation. The next step is to insert the seal concentrically into the sewer pipe so that the upper extent is situated above the lower extent. It is also important that the seal is flush with the open mouth of the sewer pipe. The closet bolts are then installed within the designated recesses. After such, the lower region of the toilet ring is inserted into the seal until contact is made whereat the toilet ring is rotated in a clockwise direction with respect to the seal until the toilet ring is secured within the seal. The following step consists of pressing the toilet ring and seal combination downwardly until the toilet ring is flush with the floor.
It should be noted that the closet bolts are, more than likely, improperly located after tightening the toilet ring within the seal. The closet bolts would inevitably effect skewed installation of the toilet if utilized in such position. As such, additional steps are required to ensure proper placement of the toilet with respect to an adjacent wall. Firstly, the seal and a floor surrounding the sewer pipe and the seal must be marked with a radial line thereby noting the position of the seal with respect to the sewer pipe and the floor. Next an angle must be determined that a line which the closet bolts define is offset from being parallel with the adjacent wall. Upon such determination, the toilet ring is separated from the seal by rotating the toilet ring counterclockwise with respect to the seal after which the seal is removed from the sewer pipe. The seal is then ready to be inserted within the sewer pipe again so that the marking on the floor and the marking on the seal are offset by said angle. After this, steps may be repeated to reinstall the toilet ring and subsequently secure the toilet in a proper orientation.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
