Abstract

A skirted toilet assembly, comprising a toilet bowl having a sump outlet; and a wall extending around the bowl from a first rear edge to a second rear edge; wherein the wall, the first rear edge, and the second rear edge define a space within the wall, the sump outlet is configured to couple to a trapway, the trapway is configured to fluidly couple the sump outlet with a sewer outlet, and the trapway is configured to be disposed within the space. A trapway may be a thermoplastic and the sump outlet a ceramic.

First claim

The invention claimed is:

1. A toilet assembly, comprising
a toilet bowl having a sump outlet;
a wall extending around the bowl from a first rear edge to a second rear edge; and
a trapway,
wherein
the wall, the first rear edge, and the second rear edge define a space within the wall,
the sump outlet comprises a substantially horizontal portion which extends outward from a toilet bowl substantially vertical portion,
the sump outlet substantially horizontal portion and the toilet bowl substantially vertical portion are coupled to the trapway via a sump connection,
the trapway is configured to fluidly couple the sump outlet with a sewer outlet,
the trapway is disposed within the space,
the sump connection comprises a primary seal and a secondary seal, the primary seal being formed with a sump outlet substantially horizontal portion exterior surface and a trapway interior surface, and the secondary seal being formed with a toilet bowl substantially vertical portion surface and a trapway upstream end, or
the sump connection comprises a flexible sleeve coupled to a sump outlet adapter and to the trapway, the sump outlet adapter coupled to the sump outlet substantially horizontal portion exterior surface and to the toilet bowl substantially vertical portion surface, and the flexible sleeve coupled to a sump outlet adapter exterior surface and to a trapway exterior surface, and
the trapway comprises a plastic and the toilet bowl and sump outlet comprise a ceramic.

2. The toilet assembly according to claim 1 , wherein the sump connection comprises the primary seal and the secondary seal.

3. The toilet assembly according to claim 2 , wherein the primary seal comprises a discrete ring positioned between the sump outlet substantially horizontal portion exterior surface and the trapway interior surface.

4. The toilet assembly according to claim 2 , wherein the primary seal comprises a first gasket and the secondary seal comprises a second gasket.

5. The toilet assembly according to claim 1 , wherein the sump connection comprises the sump outlet adapter and the flexible sleeve.

6. The toilet assembly according to claim 5 , wherein the flexible sleeve comprises a feature configured to receive a hose clamp.

7. The toilet assembly according to claim 1 , comprising a bridge extending from the first rear edge to the second rear edge and configured to support the trapway.

8. The toilet assembly according to claim 1 , wherein the sump outlet substantially horizontal portion extends from about 8 mm to about 100 mm outward from the toilet bowl.

9. The toilet assembly according to claim 1 , wherein the sump connection is configured to allow for movement of the trapway.

10. The toilet assembly according to claim 1 , wherein the sump connection comprises a flexible joint.

11. The toilet assembly according to claim 1 , wherein the sump connection comprises an adhesive.

12. The toilet assembly according to claim 1 , wherein the trapway is concealed within the space.

13. The toilet assembly according to claim 7 , wherein the trapway is coupled to the bridge.

14. The toilet assembly according to claim 1 , comprising a drain connection configured to couple the trapway to a sewer outlet, wherein the drain connection is configured to couple to the wall.

15. The toilet assembly according to claim 1 , comprising a jet channel pipe extending from a jet channel inlet to a jet channel outlet.

16. The toilet assembly according to claim 15 , wherein the jet channel pipe comprises a rubber and/or a thermoplastic.

17. The toilet assembly according to claim 7 , wherein the bridge comprises a recess configured to receive a heel of the trapway.

18. The toilet assembly according to claim 7 , wherein the trapway comprises a flange, and wherein the assembly comprises one or more fixing parts configured to mate with and couple to the flange.

19. The toilet assembly according to claim 18 , wherein the one or more fixing parts are coupled to the bridge.
