Abstract

The present invention is a flush valve adapter that will provide a dual flush. This is installed within a new or existing flush tank. The discharge opening is in communication with the flush tank outlet and the inlet opening of the toilet bowl. Separate operator handles are provided for the flush valve adapter so that the appropriate flush handle can be selectively used to dispose of waste material. The present invention can be used in two circumstances:

- 1. As shown in FIG. 2 used in conjunction with the existing flush valve.
- 2. Use with new tank construction and eliminate FIG. 3 and FIG. 4 by adding a second handle hole in the tank wall. Standard commercial handles and levers can be used.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

See patent application Ser. No. 10/614705—July, 07, 2003 Filed by myself, Paul B. McKee, for a Dual Flush Valve patent on Jun. 30, 2003 using the same flush handles to be used on existing toilet tanks as shown in this patent application for a Dual Flush Valve. See FIGS. 5 and 6.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to the field of toilet devices, and more particularly to a dual flush toilet that conserves water.
2. Description of Related Art
As can be seen by reference to the U.S. Pat. Nos. 5,067,180-5,111,537-5,887,292 and 6,173,456. The prior art is replete with myriad and diverse bathroom fixtures designed to conserve water.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformaly deficient with respect to their failure to provide a simple, efficient and practical toilet that effectively conserves water. My “FLUSH VALVE ADAPTOR” will correct all of these deficiencies. As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved “DUAL FLUSH TOILET ADAPTER” and the provision of such a construction is a stated objective of the present invention.

BRIEF SUMMARY OF THE SEVERAL VIEWS OF THE DRAWINGS

FIG. 1 is a top plan view of the flush valve adapter.
FIG. 2 is a front elevation sectional view of the flush valve adapter when it is used with the existing flush valve or built into a new flush tank.
FIG. 3 shows a 2× size view of the flush handles on the exterior of the existing tank.
FIG. 4 shows full scale view of flush handle levers on the interior of the existing tank.
Note:
For FIG. 3 and FIG. 4

- In new tank construction a second handle hole is opened in the wall of the new tank, then standard commercial flush handles and levers may be used thereby eliminating DET's 15 thru 27 in FIGS. 3 and 4.

BRIEF SUMMARY OF THE INVENTION

As can be seen by reference to the drawings and in particular to FIG. 1 and FIG. 2 the flush valve adapter that forms the basis of the present invention is designated generally by the reference FIG. 1 and FIG. 2.
The float 1 (and 2 which threads 1) and can be moved up or down to provide float adjustment to desired setting for float 3.
Chain 12 attaches to lever 24 and latch 9 and flap 14. Disc 5 (2 req.) thread onto 2. Use one disc 5 to push down flap 14 if needed. Float 3 and 4 are cemented together. 7 is secured to existing flush valve 13 by screw 10. Pin 8 (2 req.) is pressed into 7 and slips into 9 which in turn slips into 7. 11 (scr.) is used to attach 12 to 9. Chain 27 attaches to 14 and 25.
The existing flush tank has a water supply inlet that provides water to the existing toilet tank and float shut-off valve 13.
As best shown in FIG. 3, this 2× size view shows handles on exterior of existing tank. See 15 thru 21 in FIG. 3.
As best shown in FIG. 4 the levers are installed thru the existing square hole in the existing wall from the exterior to the interior of existing tank. See 22 thru 27 in FIG. 4.
See note for FIG. 3 and FIG. 4 on page 5 of Brief Summary.
Although only an exemplary embodiment of the invention has been described in detail above, those skilled in the art will readily appreciate that many modifications are possible without materially departing from the novel teachings and advantages of this invention accordingly, all such modifications are intended to be included within the scope of this invention as defined in the following claims.
The float 3 moves with the water flow to close flap 14 to provide a partial flush when handle 15 and lever 24 are activated.
When the existing fill valve re-opens to provide water to replace the water used in the partial flush the float valve 3 will rise until the float 3 and 4 locks itself in place under latch 9. Float 3 rises on 13 against 1.
When a full flush is required and the handle 16 and lever 25 is activated and the float valve 3 is locked in place by 9 and can not be released until the partial flush handle 15 is activated.
The present invention provides a flush toilet valve adapter within a flush tank. The valve flap 14 works independently with the required flush handle.
The discharge opening is in communication with the flush tank outlet and the inlet opening of the toilet bowl.
Two operator handles are provided for the separate flush choices (full or partial) so that the appropriate flush valve flap 14 can be selectively opened to dispose of waste material.
The partial flush float 3 will conserve many gallons of water each day and result in significant savings. This design may be adapted to existing toilet tanks or can be provided as original equipment.

Claims

1. This invention to be used with existing and new flush tanks that have a water supply and a Float shut-off valve.

2. Float 3 moves with water flow and locks in the up position by 9 so full flush can be obtained.

3. Partial flush is activated by handle 15 and lever 24 to release float 3 which is held in the up position by 9 which is chained to 12 and lever 24.

4. Float is adjustable by threads in 1 & 2.

5. I claim that the basis of this invention is to provide an inexpensive device that will save both water and money.

6. I claim that there is no need to disconnect any plumbing.

7. This invention can be adjusted to determined amount of water to be flushed

Note:

The partial flush valve adapter (claim 3) will be used 80 to 85 percent of the flushings (estimated).
