Description
- The present invention relates generally to plumbing fixtures and to the component parts that are used in them, including fill valves, tubular inlet risers for fill valves and assemblies for flush systems used in gravity flush toilets. More specifically, it relates to an improved connection device of the type that is used to secure one end of an inlet water line to the tubular inlet riser of a toilet fill valve, the tubular inlet riser of the fill valve being typically anchored at the bottom of a toilet water tank.
- Conventional toilets typically employ a number of essential components. First, a porcelain water tank is mounted immediately above a porcelain bowl from which a quantity of water is rapidly drained in order to flush waste from the bowl into the sewer system. One very common design uses a flapper valve made of an elastomeric material that covers the drain outlet of the tank. When the flush handle on the outside of the tank is manually depressed the flapper valve is lifted via a chain or other connecting means and the head of water in the tank drains through the drain outlet, the outlet being normally covered by the flapper valve. The flapper valve is typically designed with an inverted air chamber so that it initially floats as it is lifted away from the drain outlet in the bottom of the tank. This allows sufficient flushing water to flow into the bowl even if the user immediately releases the flush handle. When the water level in the tank drops, the tank is automatically refilled through a fill valve that is connected to a high pressure water supply line.
- The typical fill valve for the tank comprises a tubular inlet riser that extends through an opening in the bottom of the tank and is connected to the pressurized water line. Current connections that are available include female compression to female compression with braided stainless steel hose extending between them; female compression to female compression with woven synthetic polyvinyl chloride (“PVC”) hose; copper, stainless steel or rigid PVC tubing with compression style female fittings, and Cross-linked polyethylene, commonly abbreviated PEX, piping with a threaded nut for attachment to the threaded tubular inlet riser.
- When the tank drains, a float connected to the ballcock or pilot fill valve descends. This activates the ballcock or pilot fill valve and it begins to refill the tank with water via the inlet riser at a rate that is much slower than the rate at which water flows through the drain outlet. When the tank is nearly empty, the flapper valve closes. The tank continues to refill as the float connected to the ballcock or pilot fill valve rises. At the same time water from the ballcock or pilot fill valve enters an overflow tube and refills the bowl to the normal standing water level to provide a trap seal. Once the float reaches a predetermined height indicating that the tank is full, the ballcock or pilot fill valve completely turns off and the flow of water through the inlet riser stops.
- The foregoing general conventional arrangement is still widely used today. In the experience of this inventor, however, there is a need to provide an improved water inflow quick connect device that would make it easier for home owners and plumbers to install the in-flow connection tubing to the tubular inlet riser of the fill valve at the point where the tubular inlet riser of the fill valve is anchored to the tank floor.
- In accordance with the foregoing, several constructs for making an improved in-flow connection to the tubular inlet riser of a fill valve have been devised by this inventor. In two constructs presented in this application, a male insert comprises a first end and a second end. The first end is configured in such a way that it can be captured at the bottom-most portion of the tubular inlet riser. A cone washer and a coupling nut are used to retain a peripheral flange of the male insert to that bottom-most portion of the inlet riser. The peripheral flange separates the first and second ends of the male insert. The bottommost end of the male insert, in turn, connects with one end of a conventional outer quick connect type hose, which pushes onto the fill valve outside of the male connector. The other end of the hose connects to the water outlet at the wall or floor to the rear of the toilet.
- In another construct, a “half cartridge” insert is welded in place at the bottom-most portion of the tubular inlet riser of the fill valve. A separate conventional half cartridge assembly, comprised of a pair of O-rings, a retainer and a locking collar, is used in conjunction with the welded half cartridge insert to complete a similar assembly wherein an end of in-flow connection tubing is secured within the half cartridge insert and the half cartridge assembly.
- The foregoing and other features of the quick connect device and assembly of the present invention will be apparent from the following detailed description when read in conjunction with the accompanying drawings.

FIG. 1 is a cross sectioned side elevation view of the tubular inlet riser of a fill valve with which a first embodiment of the male insert of the present invention is to be used with an in-flow connection tubing end. -
FIG. 2 is a cross sectioned side elevation view of the tubular inlet riser of a fill valve with which a second embodiment of the male insert of the present invention to be used with an in-flow connection tubing end. -

FIG. 4 is a cross sectioned view of the tubular inlet riser illustrated inFIG. 3 but showing the fill valve and quick connect device as assembled, but without showing the in-flow connection tubing. - Referring now to the drawings in detail, wherein like-numbered elements refer to like elements throughout,
FIG. 1 illustrates a first preferred embodiment of a quick connect assembly, generally identified 10, that is constructed in accordance with the present invention. Theassembly 10 comprises a tubular inlet riser 1 of the type that would be mounted within a toilet tank (not shown). A main control valve assembly (also not shown) would typically be mounted on the upper end of the inlet riser 1. The inlet riser 1 comprises aninner riser bore 5. Fill water passes through the inner riser bore 5 when the tank empties in accordance with the main control valve assembly. Thebottom-most portion 2 of the inlet riser 1 comprises an outer threaded portion 3. Though not shown, this threaded portion 3 of the inlet riser 1 is also used to secure the riser 1 to the floor of the toilet tank via a seal and a nut. Those elements are not illustrated, but mentioned for purposes of understanding why the threaded portion 3 extends as far up the bottom-most portion of a tubular inlet riser 1 as it does. Lastly, the inlet riser 1 comprises abottom seat 4. - In the
assembly 10, astandard coupling nut 12 is also provided, thecoupling nut 12 comprising aside wall 14 and anend wall 15. Inside of theside wall 14, thecoupling nut 12 comprisesinternal threads 13 that mesh with the threaded portion 3 of the inlet riser 1. The inside of thecoupling nut 12 further comprises a flatinner surface 16 of theend wall 15. Theend wall 15 further comprises a centrally-disposedcircular aperture 17. Thisassembly 10 further includes acone washer 6 which can be a pliable conforming rubber or TPE (Thermal Plastic Elastomer). Thecone washer 6 comprises a centrally-disposed circular aperture 7 and a rampedshoulder 8 that extends downwardly from the aperture 7 to a verticalouter sidewall 9. Thecone washer 6 further comprises a substantiallyflat bottom surface 11. - Lastly, the
assembly 10 of this first preferred embodiment comprises a substantiallytubular male insert 21 having anupper portion 22 and alower portion 23, thelower portion 23 having an outercylindrical surface 27. Theinsert 21 further comprises a substantially cylindrical inner bore 25. Disposed between the upper andlower portions male insert 21 is a flatperipheral flange 24, theflange 24 having atop surface 26 and abottom surface 28, thetop surface 26 having two radial rings which seal with thecone washer 6. In thisassembly 10, theupper portion 22 of themale insert 21 is intended to be placed within the aperture 7 of thecone washer 12 and thelower portion 23 is intended to extend through theend wall aperture 17 of thecoupling nut 12. Themale insert 21 is connected with a conventional outer quick connect type hose (not shown). The other end of the hose connects to the water outlet (also not shown). - In application, the
cone washer 6 is mounted onto theupper portion 22 of themale insert 21. Thelower portion 23 is inserted into theend wall aperture 17 of thecoupling nut 12. Thecoupling nut 12 is then introduced to the bottom-most threaded portion 3 of the inlet riser 1. As thecoupling nut 12 is rotated, thecone washer shoulder 8 moves into contact with thebottom seat 4 of the inlet riser 1. Ultimately, thecoupling nut 12 is rotated to the point where thecone washer 6 is captured between thebottom seat 4 of the inlet riser 1 and thetop surface 26 of the flatperipheral flange 24 of themale insert 21, thesurface 26 having two radial rings which seal with thecone washer 6. This also seals themale insert 21 to thebottom 2 of the fill valve riser 1. Themale insert 21 is connected to a conventional outer quick connect type hose end (not shown) that is pushed onto themale insert 21, the conventional outer quick connect type hose end having barbs that engage and hold themale insert 21, and the other end of the hose connects to the water outlet. As previously alluded to, push connect fittings of this type are what are typically provided for such plumbing connections and are easier for the home owner user or plumber to install, but also provide a secure seal for the pressurized water supply that theassembly 10 is connected to. Further, it is desirable that themale insert 21 be made of a relatively rigid plastic material. - Referring now to
FIG. 2 , it illustrates a second preferred embodiment of a quick connect assembly, generally identified 20, that is constructed in accordance with the present invention. For all intents and purposes, the structural elements are virtually identical between the firstpreferred embodiment 10 and this secondpreferred embodiment 20, the major difference being the size of themale insert 21 a which, in the secondpreferred embodiment 20, comprises a reducingtaper 23 a. This allows the firstpreferred embodiment 10 to be used with one end of a one-half inch diameter outer quick connect type hose and the secondpreferred embodiment 20 to be used with one end of a three-eighths inch diameter outer quick connect type hose. - Referring now to
FIG. 3 , it illustrates a third preferred embodiment of a quick connect assembly, generally identified 30, that is constructed in accordance with the present invention. Thisassembly 30 likewise comprises a tubular inlet riser 1 of the type that would be mounted within a toilet tank where a main control valve assembly would be mounted on the upper end of the inlet riser 1. The inlet riser 1 comprises an inner riser bore 5 and fill water passes through thisbore 5 when the tank empties in accordance with the main control valve assembly. Thebottom-most portion 2 of the inlet riser 1 comprises an outer threaded portion 3 and abottom seat 4. In thisassembly 30, a halfcartridge adapter structure 32 is hermetically bonded to thebottom seat 4 of the inlet riser 1 and extends upwardly into thebore 5 of the riser 1. Theadapter structure 32 comprises a cylindrical uppertube stop cavity 33, a cylindrical medial O-ring cavity 34 and a cylindricallower cartridge cavity 35. - Complementary to this
adapter structure 32 is a conventional half cartridge subassembly, generally identified 40, for insertion into the O-ring andlower cartridge cavities cartridge subassembly 40 comprises a pair of O-rings retainer 43 and alocking collar 44. Theretainer 43 further comprises a plurality of capturingshoulders 45 and the lockingcollar 44 comprises a complementary internalcircumferential ridge 46. When theshoulders 45 are urged over theridge 46, theretainer 43 is held firmly in place by the lockingcollar 46. Referring now toFIG. 4 , it shows thehalf cartridge subassembly 40 fully inserted into theadapter structure 32. - In assembly, one end of a tube, hose or conduit (not shown) is inserted into the
retainer 43. In the preferred embodiment, the tube, hose or conduit would comprise PEX (a form of polyethylene with cross-links) tubing. The pair of O-rings ring cavity 34 and the lockingcollar 44 is inserted into thelower cavity 35. Theretainer 43, with the tube, hose or conduit attached, is inserted into the lockingcollar 44 sufficiently that the end of the tube, hose or conduit extends upwardly into theadapter structure 32 and theretainer 43 engages the lockingcollar 44, which exerts clamping pressure on the tube, hose or conduit to capture it and hold it in place. The O-rings assembly 30. Again, seeFIG. 4 . - In accordance with the foregoing, it will be apparent that several constructs for making an improved in-flow connection to the tubular inlet riser of a fill valve have been devised—two of them utilizing a male insert assembly and one of them utilizing a half cartridge assembly.
