Abstract

A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel. The bowl has a closed jet pathway to maintain the jet channel in a primed state with fluid from the jet flush valve assembly to prevent air from entering the closed jet pathway. Flush valves may have back-flow preventer mechanisms and/or at least partly flexible valve covers, including specific valve cover structures. Flush activation assemblies may have a flush activation bar connected to the pivot rod and/or an adjustable flush connector located between the pivot rod and the flush activation bar. A kit providing one or more flush activation elements is included. The kit elements may be usable with the toilet systems and methods described.

First claim

We claim:

1. An adjustable flush connector for a flush toilet comprising
a first section having a first rotatable connector;
a second section; and
an adjustable connector having a second rotatable connector, the adjustable connector having a surface being longitudinally movable along and rotational positionable around a surface of the second section.

2. The adjustable flush connector according to claim 1 , wherein the flush toilet is a siphonic flush toilet.

3. The adjustable flush connector according to claim 1 , wherein a portion of a surface of the second section and an interior surface of the adjustable connector, defining a passage therethrough, are each threaded to allow the adjustable connector to be longitudinally and rotationally adjusted along the second section.

4. The adjustable flush connector according to claim 1 , wherein the first rotatable connector is configured so as to be connectable to a pivot rod.

5. The adjustable flush connector according to claim 1 , wherein the second rotatable connector is configured so as to be connectable to a flush activation bar.

6. The adjustable flush connector according to claim 1 , wherein the second rotatable connector is configured so as to be connectable to a flush activation bar comprising a first portion connected to a first valve assembly and a second portion connected to a second valve assembly.

7. A flush activation assembly for use in a flush toilet comprising
a flush activation bar comprising a first portion and a second portion, the first portion configured to be connected to a first valve assembly and the second portion configured to be connected to a second valve assembly;
a pivot rod; and
a connector positioned through an opening in the flush activation bar and positioned so as to operably connect the pivot rod and the flush activation bar.

8. The flush activation assembly according to claim 7 , wherein the connector is an adjustable flush connector, the adjustable flush connector comprising a first section, a second section and an adjustable connector,
wherein the adjustable connector comprises a second rotatable connector and the adjustable connector is longitudinally movable along the second section of the adjustable flush connector and rotationally positionable;
wherein the adjustable flush connector is connected to the pivot rod using a first rotatable connector located on the first section of the adjustable flush connector, and the adjustable flush connector is connected to the flush activation bar using the second rotatable connector of the adjustable connector.

9. The flush activation assembly according to claim 8 , wherein the flush toilet is a siphonic flush toilet.

10. The flush activation assembly according to claim 8 , wherein a portion of a surface of the second section of the adjustable flush connector and an interior surface of the adjustable connector, defining a passage therethrough, are each threaded to allow the adjustable connector to longitudinally and rotationally adjust along the second section of the adjustable flush connector.

11. The flush activation assembly according to claim 8 , wherein the first portion of the flush activation bar is configured to be connected to a rim valve assembly.

12. The flush activation assembly according to claim 8 , wherein the second portion of the flush activation bar is configured to be connected to a jet valve assembly.

13. The flush activation assembly according to claim 8 , wherein at least one of the first portion of the flush activation bar and the second portion of the flush activation bar is configured to connect to a valve assembly having a valve body and a valve cover comprising a seal and a rigid cover configured to be capable of bending the seal to gradually open the valve.

14. The flush activation assembly according to claim 13 , wherein the seal comprises a sealing surface and a locking surface, wherein the locking surface comprises a plurality of locking lugs positioned on the locking surface so as to engage a plurality of corresponding openings in the rigid cover.

15. The flush activation assembly according to claim 13 , wherein the seal comprises a sealing surface and a locking surface, and at least the sealing surface comprises silicone.

16. A siphonic flush toilet comprising
a toilet;
a toilet tank having a first tank outlet and a second tank outlet, the first tank outlet being separate from the second tank outlet;
a first valve assembly having a first outlet aligned with the first tank outlet;
a second valve assembly having a second outlet aligned with the second tank outlet; and
a flush activation assembly comprising
a flush activation bar comprising a first portion and a second portion, the first portion configured to be connected to the first valve assembly and the second portion configured to be connected to the second valve assembly;
a pivot rod; and
an adjustable flush connector positioned so as to operably connect the pivot rod and the flush activation bar, the adjustable flush connector comprising a first section, a second section of the adjustable flush connector and an adjustable connector, wherein the adjustable connector comprises a second rotatable connector and the adjustable connector is longitudinally movable along the second section and rotationally positionable, and the adjustable flush connector is connected to the pivot rod using a first rotatable connector located on the first section of the adjustable flush connector, and the adjustable flush connector is connected to the flush activation bar using the second rotatable connector of the adjustable connector.

17. The siphonic toilet according to claim 16 , wherein the first valve assembly is a rim flush valve assembly.

18. The siphonic toilet according to claim 16 , wherein the second valve assembly is a jet flush valve assembly.

19. An assembly kit for use in a flush toilet comprising
a first valve assembly;
a second valve assembly; and
a flush activation assembly comprising
a flush activation bar comprising a first portion and a second portion; and
an adjustable flush connector positioned so as to operably connect a pivot rod and the flush activation bar, the adjustable flush connector comprising a first section, a second section of the adjustable flush connector and an adjustable connector, wherein the adjustable connector comprises a second rotatable connector and the adjustable connector has a surface being longitudinally movable along and rotationally positionable around a surface of the second section, and the adjustable flush connector is configured to connect to the pivot rod using a first rotatable connector located on the first section of the adjustable flush connector and the adjustable flush connector is connected to the flush activation bar using the second rotatable connector of the adjustable connector.

20. An assembly kit according to claim 19 , wherein the flush toilet is a siphonic flush toilet.

21. An assembly kit according to claim 19 , wherein the second valve assembly comprises a float attachment.
