Abstract

A faucet includes a spout base having a first end mounted to a mounting surface and a second end opposite the first end that includes an elbow, more than one water supply line within the spout base, and a hub containing a mixing valve. The hub includes an inlet end and an outlet end. The second end of the spout base and the inlet end of the hub connect together. The inlet end of the hub connects to the water supply lines. The mixing valve is approximately midway between the elbow and a dispensing end of the faucet.

First claim

What is claimed is:

1. A faucet for mounting to a mounting surface, the faucet comprising:
a spout base having a first end, a second end, and a first elbow located between the first and second ends, wherein the first end is configured to mount to the mounting surface;
a hub including a mixing valve, an exterior inlet end coupled to the second end of the spout base, and an exterior outlet end opposite from and coaxial with the exterior inlet end;
a spout outlet including a first portion extending from the exterior outlet end of the hub, a second portion having a fluid outlet, and a second elbow located between the first and second portions; and
a plurality of water supply lines received within the spout base and fluidly coupled to the mixing valve through the exterior inlet end of the hub.

2. The faucet of claim 1 , wherein the first portion of the spout outlet extends generally horizontally from the exterior outlet end of the hub and the second portion extends generally vertically downward from the first portion when the faucet is mounted to the mounting surface.

3. The faucet of claim 2 , wherein the mixing valve is located within a bore in a top portion of the hub.

4. The faucet of claim 3 , wherein the top portion includes a cylindrical wall that extends generally vertically upward and an opening at the top to receive the mixing valve therethrough.

5. The faucet of claim 4 , further comprising a fastener that threads to the cylindrical wall to secure the mixing valve within the hub.

6. The faucet of claim 5 , further comprising a handle coupled to a stem of the mixing valve for controlling a flow rate of water through the mixing valve to the fluid outlet.

7. The faucet of claim 6 , further comprising:
an escutcheon rotatably supporting the handle and closing the opening at the top of the cylindrical wall; and
a nut coupling the escutcheon to the cylindrical wall.

8. The faucet of claim 1 , wherein the hub is located approximately midway between the first elbow and the second elbow.

9. The faucet of claim 1 , further comprising a handle coupled to a stem of the mixing valve for controlling a flow rate of water from the plurality of water supply lines to the fluid outlet, wherein the stem extends generally vertically upward when the faucet is mounted to the mounting surface such that the handle is above the hub, the spout base, and the spout outlet.

10. The faucet of claim 9 , further comprising a pin to secure each water supply line to the hub by engaging a connector of each water supply line.

11. The faucet of claim 10 , wherein the pin extends through an opening in the hub in a direction generally parallel to the stem of the mixing valve.

12. The faucet of claim 10 , wherein the pin further secures a plug within an outlet hole fluidly connecting the hub and the spout base, and wherein the plug is configured to prevent water from flowing from the hub back to the spout base.

13. A faucet for mounting to a mounting surface and configured to receive a supply of hot water from a first supply line and a supply of cold water from a second supply line, the faucet comprising:
a spout base having an inlet section, an outlet section, and a first elbow located between the inlet and outlet sections of the spout base, wherein the inlet section is configured for mounting to the mounting surface;
a spout outlet including an inlet section, an outlet section having a fluid outlet, and a second elbow located between the inlet and outlet sections of the spout outlet;
a hub having an exterior inlet end coupled to the outlet section of the spout base and an exterior outlet end that is opposite from and coaxial with the exterior inlet end and is coupled to the inlet section of the spout outlet; and
a mixing valve disposed within the hub for receiving the hot water and the cold water and for outputting hot water, cold water, or a mixture thereof to the fluid outlet.

14. The faucet of claim 13 , wherein each elbow of the first and second elbows is configured to position the associated outlet section at about ninety degrees relative to the associated inlet section.

15. The faucet of claim 13 , wherein the outlet section of the spout base extends along a longitudinal axis and the inlet section of the spout outlet extends along the longitudinal axis.

16. The faucet of claim 13 , wherein the mixing valve is received in a bore extending through a top surface of the hub.

17. The faucet of claim 16 , further comprising a handle assembly comprising:
a handle coupled to a stem of the mixing valve for controlling a flow rate of hot water, cold water or a mixture thereof to the fluid outlet;
an escutcheon rotatably supporting the handle and closing the bore in the top surface of the hub; and
a fastener coupling the escutcheon to the hub to retain the mixing valve in the bore and to couple the handle assembly to the hub.

18. A faucet for mounting to a mounting surface and configured to receive a supply of hot water from a first supply line and a supply of cold water from a second supply line, the faucet comprising:
a spout base comprising:
a first section having an inlet, an outlet, and at least one elbow located between the inlet and the outlet of the first section;
a second section having an inlet, an outlet, and at least one elbow located between the inlet and the outlet of the second section, wherein the inlet is coupled to the outlet of the first section;
a hub having an exterior inlet end, which is coupled to the outlet of the second section, and an exterior outlet end, which is opposite from and coaxial with the exterior inlet end;
a spout outlet including an inlet section, an outlet section having a fluid outlet, and at least one elbow located between the inlet and outlet sections of the spout outlet, wherein the inlet section is coupled to the exterior outlet end of the hub; and
a first valve disposed within the hub for controlling the flow of water from the hub to the spout outlet.

19. The faucet of claim 18 , further comprising a second valve for mounting to the mounting surface, wherein the second valve is coupled to the inlet of the first section of the spout base and controls the flow of water into the spout base.

20. The faucet of claim 19 , wherein one of the first and second valves is a flow control valve and the other of the first and second valves is a mixing valve, and wherein the first and second supply lines are configured to be coupled to the mixing valve.
