Abstract

A lavatory includes a basin including a bottom surface, the basin configured to hold a volume of water; and a drain opening disposed in the bottom surface of the basin. The bottom surface of the basin includes a substantially horizontally extending projection formed integrally with the bottom surface of the basin. The horizontally extending projection is disposed over the drain opening such that the drain opening is at least partially obscured from a view of a user.

First claim

What is claimed is:

1. A lavatory comprising:
a basin comprising a bottom surface, the basin configured to hold a volume of water;
a drain opening disposed in the bottom surface of the basin; and
a drain assembly comprising:
a pipe moveable from a first position to a second position;
a first connector comprising a first end portion comprising an inner diameter and a second end portion comprising an inner diameter and an outer diameter; and
a second connector comprising a first end portion comprising an inner diameter configured to fit over and around the outer diameter of the second end portion of the first connector,

wherein in the first position an end of the pipe is configured to be housed within an inner surface of the first connector and in the second position the end of the pipe is configured to be housed within an inner surface of the second connector,
wherein the bottom surface of the basin comprises a horizontally extending projection formed integrally with the bottom surface of the basin,
wherein the horizontally extending projection is disposed over the drain opening such that the drain opening is at least partially obscured from a view of a user,
wherein the basin further comprises a chamber disposed beneath and in fluid communication with the drain opening,
wherein the chamber is configured to receive a first fluid flow from the drain opening and provide a second fluid flow to a waste,
wherein the chamber is configured to house at least a portion of the pipe, the pipe in fluid communication with the waste, and
wherein the first end portion of the first connector is configured to be connected to the fluid outlet of the chamber.

2. The lavatory according to claim 1 , further comprising:
a connecting rod connected to the overflow pipe and extending at least partially from the overflow pipe; and
a pop-up rod assembly connected to the connecting rod, the pop-up rod assembly being configured to control a movement of the overflow pipe.

3. The lavatory according to claim 1 , wherein the first connector is configured to be fluidly sealed to a fluid outlet of the chamber.

4. The lavatory according to claim 3 , wherein the second connector is configured to be fluidly sealed to the first connector and further configured to be connected to the waste.

5. A lavatory system comprising:
a basin configured to hold a volume of water, the basin comprising:
a bottom surface; and
a drain opening disposed in the bottom surface of the basin; and

a hidden chamber disposed beneath the basin, the hidden chamber comprising a fluid inlet, and a fluid outlet, the hidden chamber configured to receive a fluid flow from the drain opening of the basin; and
a drain assembly comprising:
an overflow pipe comprising a first end and a second end, the overflow pipe being moveable from a first position to a second position;
a waste in fluid communication with the fluid outlet of the hidden chamber;
a first connector comprising a first end portion comprising an inner diameter and a second end portion comprising an inner diameter and an outer diameter; and
a second connector comprising a first end portion comprising an inner diameter configured to fit over and around the outer diameter of the second end portion of the first connector,

wherein the first end portion of the first connector is configured to be connected to the fluid outlet of the hidden chamber,
wherein in the first position an end of the overflow pipe is configured to be housed within an inner surface of the first connector and in the second position the end of the overflow pipe is configured to be housed within an inner surface of the second connector, and
wherein in the first position of the overflow pipe, fluid flows from the hidden chamber into the waste without flowing through the overflow pipe, and in the second position of the overflow pipe, fluid flow flows from the hidden chamber into the waste via the overflow pipe.

6. The lavatory system according to claim 5 , wherein the basin is configured to hold a volume of water when the overflow pipe is in the second position.

7. The lavatory system according to claim 5 , wherein the bottom surface of the basin comprises a horizontally extending projection formed integrally with the bottom surface of the basin, and
wherein the horizontally extending projection is disposed over the drain opening such that the drain opening is at least partially obscured from a view of a user.

8. The lavatory system according to claim 5 , wherein the first end of the overflow pipe is housed within the hidden chamber.

9. The lavatory system according to claim 5 , further comprising a connecting rod connected to the overflow pipe and extending at least partially from the second end of the overflow pipe.

10. The lavatory system according to claim 9 , further comprising a pop-up rod assembly connected to the connecting rod, the pop-up rod assembly being configured to control a movement of the overflow pipe from the first position to the second position.

11. A lavatory system comprising:
a basin configured to hold a volume of water, the basin comprising
a bottom surface; and
a drain opening disposed in the bottom surface of the basin;

a hidden chamber disposed beneath the basin, the hidden chamber comprising a fluid inlet and a fluid outlet and configured to receive a fluid flow from the drain opening of the basin; and
a drain assembly comprising:
a pipe configured to receive the fluid flow, the pipe being moveable from a first position to a second position;
a first connector comprising a first end portion comprising an inner diameter and a second end portion comprising an inner diameter and an outer diameter; and
a second connector comprising a first end portion comprising an inner diameter configured to fit over and around the outer diameter of the second end portion of the first connector and a second end portion configured to be connected to a first waste,

wherein the first end portion of the first connector is configured to be connected to the fluid outlet, and
wherein in the first position an end of the pipe is configured to be housed within an inner surface of the first connector and in the second position the end of the pipe is configured to be housed within an inner surface of the second connector.

12. The lavatory system according to claim 11 , wherein in the first position of the pipe, the drain assembly is configured to allow a fluid flow from the drain opening into the first waste without flowing through the pipe, and
wherein in the second position, the drain assembly is configured to allow a fluid flow from the drain opening into the first waste via the pipe.

13. The lavatory system according to claim 11 , wherein the outer diameter of the second end portion of the first connector comprises a thread and the inner diameter of the first end portion of the second connector comprises a thread configured to mate with the thread of the outer diameter of the second end portion of the first connector.

14. The lavatory system according to claim 11 , further comprising a second waste configured to be housed within an inner surface of the second connector.

15. The lavatory system according to claim 11 , wherein at least a portion of the pipe is configured to be housed in the hidden chamber.

16. The lavatory system according to claim 11 , wherein the first waste is connectable to an external plumbing system.

17. The lavatory system according to claim 11 , further comprising a pop-up rod assembly;
wherein the pipe includes a connecting rod connected to the
