Abstract

A wall hung toilet is described which has a toilet body having a toilet body inlet, a back plate having at least a first and a second lower fastener opening therethrough, a toilet body outlet, a bowl and a base. The bowl has an interior surface defining a interior area for receiving fluid, an inlet for introducing fluid to the interior area of the bowl and a bowl outlet. A trapway for passing fluid from the bowl outlet to the toilet body outlet is also included. The base of the toilet body extends from a front bowl portion of the base to a rear portion of the base that contacts the back plate, and the base is configured so as to distribute load bearing forces when applied to the bowl in use towards each of a first area around the first fastener opening and a second area around the second fastener area.

First claim

We claim:

1. A wall hung toilet, comprising
a toilet body having a toilet body inlet, a back plate having at least a first and a second fastener opening therethrough which are situated on a lower portion of the back plate, a toilet body outlet, a bowl and a base;
wherein the bowl has an interior surface defining a interior area for receiving fluid, an inlet for introducing fluid to the interior area of the bowl and a bowl outlet; and
a trapway for passing fluid from the bowl outlet to the toilet body outlet,
wherein the base of the toilet body has a lower surface with a generally V-shaped configuration in lower plan view, said base having a first angled wall and a second angled wall which each extend from a front bowl portion of the base to a rear portion of the base that contacts the back plate, wherein the first and second angled walls meet the back plate at a distance measured transversely from an exterior surface of the first or second angled wall along the back plate to a longitudinal axis through a center of the first or second fastener opening closest to the first or second angled wall of less than about 5 cm such that the base distributes load bearing forces when applied to the bowl in use towards each of a first area around the first fastener opening and a second area around the second fastener opening.

2. The wall hung toilet according to claim 1 , wherein the toilet body inlet is configured to receive a flushing fixture.

3. The wall hung toilet according to claim 1 , wherein the toilet body further comprises a jet and a rim inlet, each for receiving fluid passing through the toilet body inlet.

4. The wall hung toilet according to claim 3 , wherein the bowl is a rimless bowl and the rim inlet feeds water directly into the bowl along the interior surface of the bowl.

5. The wall hung toilet according to claim 1 , wherein the toilet body further comprises a rim that extends substantially around the upper periphery of the bowl and defines a rim channel, and wherein the rim has an inlet in fluid communication with a manifold beneath the toilet bowl inlet and the rim has at least one rim outlet for allowing fluid to pass from within the rim channel to the interior area of the bowl.

6. The wall hung toilet according to claim 5 , wherein the jet defines a jet path therethrough and the jet has an inlet in fluid communication with the manifold and a jet outlet in fluid communication with the interior area of the bowl in a sump area.

7. The wall hung toilet according to claim 1 , wherein the fastener openings are bolt holes and are each configured for receiving a mounting bolt.

8. The wall hung toilet according to claim 1 , having at least four fastener openings, wherein each of the fastener openings is a bolt hole configured for receiving a mounting bolt.

9. The wall hung toilet according to claim 8 , wherein two of the at least four fastener openings are in an upper portion of the back plate.

10. The wall hung toilet according to claim 1 , wherein the distance from the exterior surface of the first angled wall to the longitudinal axis through the center of the closest fastener opening is less than about 3 cm.

11. The wall hung toilet according to claim 1 , wherein the toilet is capable of bearing a load of at least 1500 pounds in use when fully installed on a wall.

12. The wall hung toilet according to claim 11 , wherein the toilet is capable of bearing a load of at least 2,000 pounds in use when fully installed on a wall.

13. A wall hung toilet, comprising
a toilet body having a toilet body inlet, a back plate having at least a first and a second fastener opening therethrough in a lower portion of the back plate, a toilet body outlet, a bowl, a jet, a rim inlet, a manifold and a base, wherein the manifold is beneath the toilet body inlet for dividing flow between the jet and the rim inlet;
wherein the bowl has an interior surface defining a interior area for receiving fluid, an inlet for introducing fluid to the interior area of the bowl and a bowl outlet; and
a trapway for passing fluid from the bowl outlet to the toilet body outlet,
wherein the base of the toilet body has a lower surface with a generally V-shaped configuration in lower plan view, said base having a first angled wall and a second angled wall which each extend from a front bowl portion of the base to a rear portion of the base that contacts the back plate, wherein the first and second angled walls meets the back plate at a distance measured transversely from an exterior surface of the first or second angled wall along the back plate to a longitudinal axis through a center of the first or second fastener opening closest to the first or second angled wall of less than about 5 cm such that the base distributes load bearing forces when applied to the bowl in use towards each of a first area around the first fastener opening and a second area around the second fastener opening.

14. The wall hung toilet according to claim 13 , wherein the toilet body inlet is configured to receive a flushing fixture.

15. The wall hung toilet according to claim 13 , wherein the rim extends substantially around the upper periphery of the bowl and defines a rim channel, and wherein the rim has an inlet in fluid communication with the manifold and at least one rim outlet for allowing fluid to pass from within the rim channel to the interior area of the bowl.

16. The wall hung toilet according to claim 13 , wherein the jet defines a jet path within the jet and the jet has an inlet in fluid communication with the manifold and a jet in fluid communication with the interior area of the bowl in a sump area.

17. The wall hung toilet according to claim 13 , wherein the fastener opening is configured for receiving a mounting bolt.

18. A wall hung toilet, comprising
a toilet body having a toilet body inlet, a back plate having at least a first and a second fastener opening therethrough in a lower portion of the back plate, a toilet body outlet, a bowl and a base;
wherein the bowl has an interior surface defining a interior area for receiving fluid, an inlet for introducing fluid to the interior area of the bowl and a bowl outlet; and
a trapway for passing fluid from the bowl outlet to the toilet body outlet,
wherein the base of the toilet body has a lower surface with a generally angled V-shaped or curved V-shaped configuration in lower plan view, said base having a first angled wall and a second angled wall which each extend from a front bowl portion of the base to a rear portion of the base that contacts the back plate, wherein the first and second angled walls meet the back plate at an area near the first or second fastener opening that is closest thereto such that the base distributes load bearing forces when applied to the bowl in use towards each of a first area around the first fastener opening and a second area around the second fastener opening.

19. The wall hung toilet according to claim 18 , wherein the toilet is capable of bearing a load of at least 1500 pounds in use when fully installed on a wall.

20. The wall hung toilet according to claim 19 , wherein the toilet is capable of bearing a load of at least 2,000 pounds in use when fully installed on a wall.
