Abstract

A lavatory fixture having a combination, urinal and hand wash faucet for public restrooms, particularly in high traffic locations such as airports, the lavatory fixture having a urinal and hand sink combined in a single lavatory unit with a self-activated hand faucet being positioned above a urinal catch basin, the hand faucet having an associated proximity sensor to activate a water flow for washing hands, when a user'"'"'s hands are placed proximate the faucet, and the urinal having an associated proximity sensor for sensing the presence of a user proximate the urinal to flush the urinal when the user moves away from the urinal, the lavatory fixture having a common drain and an optional hand soap dispenser.

Claims

1. A combination urinal and hand wash lavatory fixture comprising:

a urinal structure with an upper portion having a water supply, a lower portion having a waste water drain and a back wall extending from the upper portion to the lower portion wherein the water supply is mounted to a surface of said urinal structure which is integrally formed with the back wall,

a water faucet connected to the water supply located in the upper portion of the urinal structure, the faucet having means for automatically discharging faucet water in the upper portion directed toward the lower portion for disposal through the waste water drain wherein the means for automatically discharging faucet water includes a proximity sensor and an electronically operated valve between the water supply and the water faucet; and

,

separate flushing means for automatically discharging flushing water from the water supply against the back wall for disposal through the waste water drain.

2. The lavatory fixture of claim 1 wherein the urinal has a divider between the upper portion of the urinal structure and the lower portion of the urinal structure.

3. The lavatory fixture of claim 2 wherein the divider is sloped from the horizontal to direct faucet water to the back wall of the urinal structure.

4. The lavatory fixture of claim 1 wherein the urinal structure has side walls and a substantially open front.

5. The lavatory fixture of claim 4 wherein the lower portion of the urinal structure has a drain basin with the drain being located in the drain basin.

6. The lavatory fixture of claim 5 wherein the upper portion of the urinal structure has a top shroud.

7. The lavatory fixture of claim 1 wherein the water supply includes a heated water supply connected to the faucet, wherein the faucet discharges heated water.

8. The lavatory fixture of claim 1 wherein the flushing means includes electronic means for automatic discharge of flushing water.

9. The lavatory fixture of claim 8 wherein the electronic means for automatic discharge of flushing water includes a proximity sensor.

10. The lavatory fixture of claim 9 wherein the flushing means includes a flushing water discharge at the upper portion of the urinal structure, and the electronic means for automatic discharge of flushing water includes an electronically operated valve between the water supply and the flushing water discharge, wherein the electronically operated valve is set to activate when the proximity sensor detects a physical object proximate the urinal structure and activates discharging flushing water from the flushing water discharge when the detected physical object is thereafter not detected.

11. The lavatory fixture of claim 1 wherein the top portion of the urinal structure includes a soap dispenser.
