BACKGROUND OF THE INVENTION
(1) Field of the Invention
The invention generally relates to wax free toilet installation systems. More particularly, the invention relates to wax free means and methods of attaching a soil pipe to a toilet in new construction or in a retrofit configuration with use of springs and/or pop-up flexible seals or rubber gaskets.
(2) Related Art
Other wax free toilet installation systems and sleeve type configurations are known in the related art. But, the related art fails to provide a kit system providing a plumber means and methods of installing an adjustable height wax free system in either new construction and for retrofit applications. In the related art, existing pipe flange units are presented in various sizes and require a plumber to stock and transport a plethora of fittings. Also the related art fails to provide a seamlessly self-adjusting height system to comport with existing elevations of plumbing components.
The prior art fails to disclose, anticipate or suggest the use of lower seals to stop the flow of sewer gasses. For example, U.S. Pat. Nos. 1,335,056 and 1,594,350 would not be code compliant in modern construction, as the two patents fail to provide for, inter alia, sewer gas stoppage as now required in all current building codes.
In the related art, plumber may be presented with a 3, 3.5 or 4 inch soil pipe flange and thus need to purchase and transport hardware for all three sizes. Also, in the related art, a plumber may be presented with toilet heights of various sizes and thus needs to purchase and transport further hardware to fit such toilet heights. In repair or retrofit work soil pipe flange sizes and height requirements are often unknown before the plumber reaches the jobsite.
In the related art, in new construction or where a new soil pipe flange is desired, there are no known systems wherein a new soil pipe flange is specifically designed for wax free installations and there are no known pop-up seals that take advantage of a custom soil pipe flange.
Thus, there is a long felt need in the art for the presently disclosed embodiments.
BRIEF SUMMARY OF THE INVENTION
The present invention overcomes shortfalls in the related art by presenting an unobvious and unique combination and configuration of springs, soil pipe flanges and pop-up seals, and other components to artfully attach a toilet to a prior art soil pipe flange for a retrofit application and to install a new custom soil pipe flange and customized pop-up seal in a new construction environment.
The disclosed pop-up seals or new rubber gaskets overcome shortfalls in the art by providing an upward bias or upward pressure during attachment between a soil pipe flange and toilet horn. The upward bias of the pop-up seals makes the disclosed systems automatically adjust to varying soil pipe flange, floor and toilet heights. The upward bias may be achieved with or without springs or other added flexible component. In the prior art, such variables in elevation would require specialized tools and a multitude of fittings. The disclosed pop-up seals provide for quick and nondestructive height adjustments that are often needed in bathroom remodeling projects where finished floor heights are often subject to a home owner's fluid design choices.
Disclosed embodiments overcome shortfalls in the prior art by providing a new retrofit pop-up seal comprising extended fins in a lower seal area. The use of extended fins allows the retrofit pop-up seal to work with either smaller (three inch diameter) or larger (3.5 and 4 inch diameter) existing soil pipe flanges. When left in place, the extended fins fill an outer void and make the retrofit pop-up seal work large diameter closet flanges or soil pipe flanges without modification. For use with smaller diameter closet flanges, the extended fins are easily removed on site by use of a knife or other common cutting tool. Thus, for retrofit work, a plumber need purchase and transport just one retrofit pop-up seal. For further ease of installation, disclosed embodiments include both prefabricated pop-up seals for both larger and smaller diameter closet pipe flanges.
The disclosed retrofit system further overcome shortfalls in the related art by use of a new spring system, with springs that are wider in base and narrow on top. A wide base allows the bottom portions of the springs to rest upon the upper face of a preexisting soil pipe flange. The direct spring to soil pipe flange contact allows for greater ease in retrofit projects were the exact diameter of a soil pipe flange is unknown and where the top surface conditions of a soil pipe flange are also unknown. Thus, the wide bottom retrofit spring comports to any existing soil pipe flange while providing an upward bias to comport with unknown construction height requirements.
For new construction or remodeling wherein there is an opportunity to set a new soil pipe flange, a new soil pipe flange is disclosed and overcomes shortfalls in the prior art. The disclosed soil pipe flanges are well suited for use with either smaller or lager diameter soil pipes. On the bottom side, the disclosed soil pipe flanges are artfully configured to act as a male coupler for larger soil pipes or as a female coupler for smaller soil pipes. On the top side, the disclosed soil pipe flanges have an excellent inner bevel system that fits well with a new pop-up seal system. The new inner bevel system also overcomes shortfalls in the art by allowing the new pop-up seal system to flex downwardly into the inner bevel area which gives the pop-up seal a greater range of useable and adjustable height.
For new construction, the disclosed pop-up seal system overcomes shortfalls in the related art by a new spring system. The lower portion of a new spring system rests within a specially configured lower spring recess void defined within the pop-up seal. By allowing flexible tension within the new pop-up seal system, the pop-up seal remains firmly attached to the inside of the inner flange area of the new soil pipe flange. This configuration keeps the surface of the soil pipe flange clear and helps keep the pop-up seal centered within the soil pipe flange.
For new construction, the disclosed pop-up seal system overcomes shortfalls in the art by use of new lower seal section that may comprise an angle section to securely and compactly fit the pop-up seal into the inner confines of the new soil pipe flange.
These and other objects and advantages will be made apparent when considering the following detailed specification when taken in conjunction with the drawings.

FIG. 1 depicts generally a disclosed embodiment 100 for retrofit use.
FIG. 2 depicts generally a disclosed embodiment 150 for use in new construction or where there is an opportunity to change out a soil pipe flange. A new soil pipe flange 370 may comprise surface face 371 connected to an inner flange area 380. The inner flange area 380 may comport with an angle section 710 of a pop-up seal 600. The angle section 710 may also be disposed within the inner pipe section 383 of the soil pipe flange.
The inner flange area 380 may attach to a transition edge 382 and an inner pipe section 383 may attach to the transition edge. In some embodiments, a pop-up seal may comprise an angle section 710 that may comport with the inner pipe section 383.
The pop-up seal 600, as well as all other seals disclosed herein may function without use of a spring or other external member.
FIG. 2 further depicts a spring 250. All springs disclosed herein may take the form or be comprised of any resilient member or component. All springs may be integrated within a pop-up seal. All pop-up seals may have their own independent means of tension or resilience and may function without a separate spring.
FIG. 3 depicts a perspective view of a soil pipe flange 300 sometimes used in existing toilet installations. The depicted soil pipe flange may be used or found with larger 3.5 or 4 inch soil pipes.
FIG. 4 depicts a perspective view of a soil pipe flange 350 sometimes used in existing toilet installations. The depicted soil pipe flange may be used or found with smaller 3 inch soil pipes.
FIG. 5 depicts a perspective view of a pop-up seal 500 used in retrofit or existing construction. The pop-up seal may comprise a concentric flexible rib area 490 that assists in the seamless, toolless and nondestructive height adjustment of the upper sealing lip 480. A smooth barrel section 465 used in combination with the attached flexible rib area 490 and lower seal area 470 provides the correct balance of rigidity and flexible adjustment. The lower seal area 470 may comprise recessed sealing fins 472 and extended fins 471. For use in larger diameter soil pipe flanges, the extended fins 471 may be retained. For use in smaller diameter soil pipe flanges, the recessed sealing fins 472 may be used and the extended fins 471 are removed. This seal may operate with or without use of springs or other supplemental components.
FIG. 6 depicts either a custom pop-up seal manufactured without extended fins of FIG. 5 or the pop-up seal of FIG. 5 with the extended fins removed. Disclosed embodiments include the fabrication of both pop-up seals with extended fins and without extended fins.
FIG. 7 depicts a perspective view of a retrofit system 100 comprising a pop-up seal 450 for retrofit construction and a general existing soil pipe flange 325. The soil pipe flange is shown in attachment to a soil pipe 800.
FIG. 8 depicts a perspective view of a retrofit system, such as the system of FIG. 7, but with the addition of a spring 200. The spring 200 may rest upon an upper surface face 371 of the soil pipe flange.
FIG. 9 depicts a perspective view of a soil pipe flange 375 used in new construction or where a new soil pipe flange is needed. The new soil pipe flange overcomes shortfalls in the art by use of a new inner flange area 380 that comports or mates with an angle section 710 of a pop-up seal 600 as shown in FIG. 10. The angle section 710 may also be disposed within an inner pipe section of the soil pipe flange.
FIG. 10 depicts perspective view of a pop-up seal 600 for new construction used with a spring 250. Unlike the pop-up seal for retrofit construction, the pop-up seal for new construction features a lower seal section 700 that comprises or defines a spring recess 720 or void for retaining the lower coils of a spring. The use of a spring recess 720 provides advantages not found in the prior art as the spring 250 is contained within the pop-up seal and not subject to sliding upon the face of a soil pipe flange. The integration of the spring within the spring recess 720 allows the pop-up seal 600 to be deformed into a near flattened position, thus increasing the range of pop-up elevations. The pop-up seal overcomes shortfalls in the art by use of an upper sealing lip 680 that is larger in diameter than the lower seal section 700 which allows the pop-up seal to compactly compress within the confines of an inner flange area 380 of a soil pipe flange.
FIG. 11 depicts a new construction system and a perspective view of the components of FIG. 10 in an assembled condition. The configuration of the pop-up seal 600, spring 250 and a new construction soil pipe flange 375 allows for the spring and pop-up seal to be compressed within the inner voids of the soil pipe flange. In a most compressed position, the upper sealing lip 680 of the pop-up seal 600 may be disposed within the inner flange area 380. This feature overcomes shortfalls in the art by providing, if needed, a toilet installation flush with the upper surface or surface face 371 of the soil pipe flange. Thus, the disclosed configurations of the spring 250, pop-up seal 600 and soil pipe flange provide unique and new advantages that overcome shortfalls in the prior art.
FIGS. 12, 13 and 14 provide various views of a unique spring 200 used with the disclosed retrofit systems. The retrofit spring 200 has a wider base 205 and a narrower top end 207. This configuration overcomes shortfalls in the related art by allowing the bottom portion 255 of the spring to sit upon an upper surface or surface face of a soil pipe flange. Thus, the wider base allows for more versatility in retrofit systems were unknown sizes of soil pipe flanges will be encountered at jobsites. The narrow top end 207 overcomes shortfalls in the art by providing an artful integration with an upper sealing lip of a pop-up seal.
FIGS. 15, 16 and 17 provide various views of a unique spring 250 used with the disclosed systems for new construction. The new construction spring 250 has a top section 255 that is slightly wider than the bottom end 257 or base section. The top end 255 and the base section 257 may be considered substantially similar in width. This configuration overcomes shortfalls in the art as the spring 250 base section fits or integrates with the spring recess void 720 of the pop-up seal. This bottom side spring integration overcomes shortfalls in the art as the bottom side of the spring does not sit upon the top surface of a soil pipe flange, which could allow slippage, wear or damage to the spring or soil pipe flange top surface.
The top end 255 or top configuration of the spring 250 overcomes shortfalls in the related art by artfully integrating with or within a void 687 (FIG. 8 and FIG. 29) defined within the shoulder area 683 of the pop-up seal (FIG. 8 and FIG. 29) The void 687 or spring void may accept the top end 255 of the spring to urge the pop-up seal upwardly to create a seal with a toilet or toilet horn. The position of the spring void allows the spring to urge the pop-up seal in an advantageous outer and upper position against or into a toilet or toilet horn. This configuration overcomes shortfalls in the art by providing a secure wax-fee toilet installation.
FIG. 18 depicts a perspective view of a pop-up seal 450 used for retrofitting with an existing soil pipe flange. The retrofit pop-up seal comprises a smooth barrel section 465 which provides rigidity to enable a secure fit of the pop-up seal to a toilet or toilet flange. Pop-up seal 450 and all other seals and pop-up seals may be configured to operate with or without springs.
FIG. 19 depicts an elevation view of a pop-up seal 450 used for retrofitting with an existing soil pipe flange. The pop-up seal 450 may comprise an upper sealing lip 480, a concentric flexible rib area 490, a smooth barrel section 465 and a lower seal area 470.
FIG. 20 depicts a sectional view of FIG. 19 showing a pop-up seal used for retrofitting with an existing soil pipe flange.
FIG. 21 depicts an expanded view of the lower seal area 470 shown in FIG. 20. The lower seal area 470 may comprise recessed sealing fins 472, an indent void 473, and extended fins 471. The configuration of the extended fins 471 overcomes shortfalls in the art as the extended fins may be removed to configure the pop-up seal to comport with a smaller diameter soil pipe flange.
The configuration of the recessed sealing fins 472 overcomes shortfalls in the art by providing frictional attachment to larger diameter soil pipe flanges. In such a configuration, the extended fins are removed. The artful and unobvious combination of recessed fins 472 disposed in a superior or upper position and extended fins 471 disposed in an inferior or lower position overcomes shortfalls in the art as one pop-up seal may be used for either smaller or larger diameter soil pipe flanges. If the lower extended fins 471 are removed, the upper recessed fins 472 remain for frictional attachment to the inside of a pipe, soil pipe flange or other plumbing component.
FIG. 22 depicts an expanded view of the indent void 473 shown in FIG. 21. The indent void 473 may be defined by the lower portion of the recessed sealing fins, a flexible transition component 474 and an upper portion of the extended fins 471. The indent void 473 overcomes shortfalls in the prior art as the void may be used as a scoring section to detach the extended fins 471 from the pop-up seal. The lower seal area 470 overcomes shortfalls in the art by providing a flexible transition component 474 that allows the extended fins to flex or move without damage to the recessed fins.
FIG. 23 depicts an expanded view of components comprising an upper sealing lip 480 of a pop-up seal used for retrofitting with an existing soil pipe flange. An upper sealing lip 480 may comprise a top leg 491 of a concentric flexible rib area, a flexible transition component 482 attached to the top leg and shoulder area 483. The upper sealing lip 480 may further comprise a shoulder area 483 and the shoulder area may comprise an upper bezel 484, an upper protrusion 485 and an upper seal area 486. The shoulder area 483 may define a void 487, or spring void, the void sometimes used to accept a top end 207 of a spring 200. The void 487 or spring void is configured to urge or produce frictional attachment to a toilet or toilet horn as the shoulder area is urged upwardly. The configuration of the void 487 or spring void further overcomes shortfalls in the art as the void if defined at the outer circumference of the pop-up seal, thus securing the pop-up seal at the outer most edges of a toilet or toilet flange to achieve the best possible watertight seal.
The overall configuration of the upper sealing lip 480, flexible transition component 482 and top leg 491 of the concentric flexible rib area overcomes shortfalls in the related art by providing a flexible and secure pop-up seal that integrates with a spring. Moreover, the flexible transition component 483 may provide a displacement buffer to prevent the concentric flexible rib area from damaging the shoulder area 483.
FIG. 24 depicts an expanded view of a concentric flexible rib area 490. A concentric flexible rib overcomes shortfalls in the prior art by comprising concentric components or protrusions that are larger on the bottom and progressively smaller on top. Such a configuration allows for the compact compression of the pop-up seal. A concentric flexible rib area 490 may comprise or be attached to a top leg 491 and/or a flexible transition component 482.
FIG. 25 depicts a perspective view of a pop-up seal 600 or rubber gasket for new construction. The pop-up seal may comprise an upper seal area 686 found within a shoulder area 680. The upper seal area 686 overcomes shortfalls in the art by providing additional means of water tight attachment to a toilet and/or toilet horn. The upper sealing lip 680 overcomes shortfalls in the related art by providing rigid support of the upper seal area and/or a seal around the circumference of a toilet or toilet horn.
FIG. 26 depicts an elevation view of a pop-up seal 600 which may comprise a shoulder area 680, concentric flexible rib area 690 and an angle section 710.
FIG. 27 depicts a sectional view of FIG. 26 and depicts various components of a pop-up seal, which may comprise an upper sealing lip 680, a flexible transition component 682, a top leg 691 of a concentric flexible rib area and a lower seal section 700. The lower seal section 700 may comprise an angle section 710 and the lower seal section 700 may define a spring recess void 720.
FIG. 28 depicts an expanded view of a angle section 710 which may define a void 720 or spring recess void 720. The void 720 or spring recess void may accept the lower end 257 or narrow bottom side of a spring 250.
FIG. 29 depicts an expanded section view of a shoulder area 683 and other components of a pop-up seal. A shoulder area 683 may comprise an upper bezel 684, an upper protrusion 685, an upper seal area 686 and a void 687 or spring void defined within the shoulder area. The shoulder area may be in attachment with a flexible transition component 682 which may be attached or part of a top leg 691 of a concentric flexible rib area.
FIG. 30 depicts a sectional view of a concentric flexible rib area 690 which may comprise a top leg 691 and a flexible transition component 682. A concentric flexible rib area may also be or be referred to as flexible rib components.
