Abstract

A toilet includes a base configured to engage a floor in a bathroom, the base defining a rear wall. The toilet further includes a plurality of openings defined in the rear wall configured to couple the rear wall to at least one of a wall in a bathroom or a wall carrier. The toilet further includes a cavity formed in the rear wall and a bowl defining a sump. The toilet further includes a discharge pipe defining a discharge pipe inlet disposed at the sump and a discharge pipe outlet disposed in the cavity. The toilet further includes a lower trapway having an upper section configured to receive the discharge pipe outlet therein and a lower trapway outlet configured to be fluidly coupled to a wall carrier.

First claim

What is claimed is:

1. A toilet, comprising:
a base comprising a lower surface configured to engage a floor in a bathroom, the base defining a rear wall;
a plurality of openings defined in the rear wall configured to couple the rear wall to a wall carrier configured to be disposed on a bathroom wall;
a cavity formed in the rear wall;
a bowl defining a sump;
a discharge pipe defining a discharge pipe inlet disposed at the sump and a discharge pipe outlet disposed in the cavity; and
a trapway assembly includes an upper trapway configured to be fluidly connected to the discharge pipe outlet and a lower trapway, the lower trapway comprising:
a lower trapway outlet configured to be fluidly coupled to the wall carrier configured to be disposed on the bathroom wall; and
a mounting plate formed at the lower trapway outlet, the mounting plate comprising an annular groove configured to receive the wall carrier therein;

wherein the trapway assembly is adjustable to increase and/or decrease height of the upper trapway in a vertical direction relative to each of the discharge pipe outlet and the lower surface of the base such that, in a first installation configuration, the lower trapway is configured to be coupled to the wall carrier at a first height relative to the floor, and to be coupled to the wall carrier at a second height relative to the floor that is different from the first height, in a second installation configuration; and
wherein a height of the discharge pipe outlet relative to the floor is the same in each of the first installation configuration and the second installation configuration.

2. The toilet according to claim 1 , wherein the discharge pipe outlet defines a substantially vertical axis.

3. The toilet according to claim 1 , wherein the discharge pipe outlet is adjustably received in the upper trapway.

4. The toilet according to claim 1 , further comprising a gasket disposed annularly about the discharge pipe proximate the discharge pipe outlet;
wherein the gasket is compressed between and sealingly engages the discharge pipe and the upper trapway.

5. The toilet according to claim 1 , wherein the cavity is configured to conceal the discharge pipe outlet and the lower trapway from view when the rear wall is disposed against a wall in a bathroom.

6. The toilet according to claim 1 , further comprising a wall carrier seal received in the annular groove and disposed between and configured to sealingly engage the mounting plate and the wall carrier.

7. The toilet according to claim 6 , wherein the wall carrier seal is compressed between the mounting plate and the wall carrier when the rear wall of the base is coupled to the wall carrier.

8. The toilet according to claim 1 , wherein the plurality of openings are a plurality of vertically elongated slots.

9. The toilet according to claim 1 , wherein the rear wall is coupled directly to at least one of the wall in the bathroom or the wall carrier.

10. The toilet according to claim 1 , wherein both of the rear wall and the lower trapway are coupled directly to the wall carrier.

11. A toilet, comprising:
a base comprising a lower surface configured to engage a bathroom floor, the base defining a rear wall;
a plurality of vertically elongated openings defined in the rear wall configured to couple the rear wall to a wall carrier configured to be disposed on a bathroom wall, wherein each opening is accessible from within an interior of a bathroom when the base is positioned along the bathroom wall and is configured to receive a fastener at a plurality of heights relative to the bathroom floor;
a cavity formed in the rear wall;
a bowl defining a sump;
a discharge pipe defining a discharge pipe inlet disposed at the sump and a discharge pipe outlet disposed in the cavity; and
a trapway assembly including an upper trapway configured to be fluidly connected to the discharge pipe outlet and a lower trapway, the lower trapway comprising:
a lower trapway outlet configured to be fluidly coupled to the wall carrier configured to be disposed on the bathroom wall; and
a mounting plate formed at the lower trapway outlet, the mounting plate comprising an annular groove configured to receive the wall carrier therein;

wherein the trapway assembly is adjustable to vary the relative position of the upper trapway with respect to the lower trapway so that the lower trapway outlet is configured to be coupled to the wall carrier and is vertically offset from the lower surface of the base by a first distance when the lower trapway is in a first installation configuration, and is vertically offset from the lower surface of the base by a second distance, different than the first distance, when the lower trapway is in a second installation configuration.

12. The toilet according to claim 11 , wherein the interaction between the base and the bathroom floor is configured to support a load of a user sitting on the toilet assembly.

13. The toilet according to claim 11 , wherein the bathroom wall defines a plurality of mounting points configured to support a wall-mounted toilet; and
wherein the rear wall is coupled to the bathroom wall with a plurality of fasteners extending through the plurality of openings and the plurality of mounting points.

14. The toilet according to claim 11 , further comprising a wall carrier seal received in the annular groove and disposed between and configured to sealingly engage the mounting plate and the wall carrier.

15. The toilet according to claim 14 , wherein the wall carrier seal is compressed between the mounting plate and the wall carrier when the rear wall is coupled to the bathroom wall.

16. A method of providing a floor-mounted toilet for use with a wall carrier, comprising:
providing a trapway assembly comprising an upper trapway and a lower trapway having a lower trapway outlet at a downstream end, and a mounting plate extending outward at the lower trapway outlet, the mounting plate comprising an annular groove configured to receive a wall carrier therein;
positioning the lower trapway outlet proximate the wall carrier;
coupling the mounting plate to the wall carrier by receiving the wall carrier in the annular groove;
providing a floor-mounted toilet with a discharge pipe having a discharge pipe outlet disposed in a cavity formed in a rear wall of the toilet;
lowering the discharge pipe outlet into the upper trapway, wherein the relative position of the upper trapway with respect to the lower trapway is variable; and
coupling the rear wall of the toilet to the bathroom wall using a fastener inserted into an elongated opening defined within a front surface of the rear wall and towards the bathroom wall;
wherein the lower trapway is supported entirely independent of the floor of the bathroom via the coupling of the mounting plate to the wall carrier wherein the elongated opening is configured to allow the fastener to be inserted into the front surface of the rear wall and towards the rear surface of the rear wall when the base is positioned against the bathroom wall.

17. The method according to claim 16 , wherein the mounting plate and the rear wall are coupled to the bathroom wall at mounting points configured to support a wall-mounted toilet.

18. The method according to claim 16 , further comprising compressing a wall carrier seal between the wall carrier and the mounting plate and receiving the wall carrier seal in in the annular groove.

19. The method according to claim 16 , further comprising:
providing a gasket disposed annularly about t
