Abstract

A multi-lavatory system is preassembled to facilitate efficient installation with a minimum of connection points. The multi-lavatory system is connected to a single fluid supply line and a single drainage line. A fluid supply network conducts water from the single fluid supply line to a plurality of lavatory stations. Similarly, a drainage network conducts waste water from the plurality of lavatory stations to the single drainage line. Additionally, the multi-lavatory system includes a unitary lavatory subassembly having interconnected but spaced sink regions. Each sink region is disposed in one of the lavatory stations and is bounded at a frontal area by an upstanding contoured wall that creates an independent washing zone. This facilitates efficient production of the unitary lavatory subassembly and overall multi-lavatory system while providing each user of the system with a sense of privacy in their own independent washing zone.

Claims

1. A preassembled multi-lavatory system designed to be mounted along a wall and above a floor, the multi-lavatory system being configured for connection between a single fluid supply line and a single drainage line, comprising:

a base;

a generally unitary lavatory subassembly mounted on the base, comprised of at least two lavatory stations and a fluid flow channel extending therebetween, the fluid flow channel including a drain, each lavatory station including a sink region, each sink region being sloped so fluid entering therein flows towards the fluid flow channel, the sink regions and fluid flow channel being defined at least in part by a back wall and a front contoured wall, the front contoured wall including a front surface having at least two outwardly extending sections, each outwardly extending section defining the front of one sink region, and at least one connecting section extending between the outwardly extending sections and defining the front of the fluid flow channel, wherein the distance between the back wall and the connecting section is less than the maximum distances between the back wall and each outwardly extending section;

a shelf mounted over the generally unitary lavatory subassembly, the shelf including at least two outwardly extending portions and at least one connecting portion between the outwardly extending portions, each outwardly extending portion corresponding to one of the sink regions, wherein the distance between the back wall and the connecting portion is less than the maximum distances between the back wall and each outwardly extending portion;

a plurality of faucet mechanisms, each faucet mechanism supported by one of the outwardly extending portions and in communication with one of the lavatory stations; and

a fluid supply network in fluid communication with the single fluid supply line and the plurality of faucet mechanisms.

2. The preassembled multi-lavatory system as recited in claim 1, further comprising a drainage network configured to conduct fluid from the drain to the single drainage line.

3. The preassembled multi-lavatory system as recited in claim 1, wherein the fluid supply network is configured to be coupled to a hot water conduit and a cold water conduit of the single fluid supply line.

4. The preassembled multi-lavatory system as recited in claim 1, wherein the fluid supply network is configured to be coupled to a single conduit supplying a mixture of hot and cold water.

5. The preassembled multi-lavatory system as recited in claim 1, wherein the fluid supply network includes a plurality of connector lines, one line being connected to each of the faucet mechanisms.

6. The preassembled multi-lavatory system as recited in claim 5, further comprising a plurality of solenoid valves, wherein one solenoid valve is disposed in each connector line to selectively permit fluid flow therethrough.

7. The preassembled multi-lavatory system of claim 6, further comprising a plurality of sensors configured to sense when an individual'"'"'s hands are placed into one of the sink regions and to provide an output signal in response thereto, wherein one of the solenoid valves is connected to each sensor to permit fluid flow to that sink region in response to the signal.

8. The preassembled multi-lavatory system of claim 7, wherein the sensors are infrared sensing modules.

9. The preassembled multi-lavatory system of claim 1, wherein the base has an expanded portion and an inset portion beneath the expanded portion, the inset portion being sized to provide clearance to facilitate wheelchair access, and the base includes a framework surrounded by a shell, the framework being configured for attachment along the wall.

10. The preassembled multi-lavatory system as recited in claim 1, wherein the shelf includes a top, a bottom and an interior region disposed between the top and the bottom, and the plurality of faucet mechanisms and the fluid supply network are disposed within the interior region.

11. A preassembled multi-lavatory system designed to be mounted along a wall and above a floor, the multi-lavatory system being configured for connection between a single fluid supply line and a single drainage line, comprising:

a base;

a generally unitary lavatory subassembly mounted on the base, comprised of at least two lavatory stations and a fluid flow channel extending therebetween, the fluid flow channel including a drain, each lavatory station including a sink region, each sink region being sloped so fluid entering therein flows towards the fluid flow channel, the sink regions and fluid flow channel being defined at least in part by a back wall and a front contoured wall, the front contoured wall including a front surface having at least two outwardly extending sections, each outwardly extending section defining the front of one sink region, and at least one connecting section extending between the outwardly extending sections and defining the front of the fluid flow channel, wherein the distance between the back wall and the connecting section is less than the maximum distances between the back wall and each outwardly extending section, and wherein the generally unitary lavatory subassembly comprises a cast homogenous thermoset polymer alloy;

a shelf mounted over the generally unitary lavatory subassembly, the shelf including at least two outwardly extending portions and at least one connecting portion between the outwardly extending portions, each outwardly extending portion corresponding to one of the sink regions, wherein the distance between the back wall and the connecting portion is less than the maximum distances between the back wall and each outwardly extending portion;

a plurality of faucet mechanisms, each faucet mechanism supported by one of the outwardly extending portions and in communication with one of the lavatory stations; and

a fluid supply network in fluid communication with the single fluid supply line and the plurality of faucet mechanisms.

12. The preassembled multi-lavatory system as recited in claim 11, wherein the fluid supply network has one supply connection point.

13. The preassembled multi-lavatory system as recited in claim 11, further comprising a plurality of solenoid valves connected to the fluid supply network to regulate water flow to the lavatory stations.

14. The preassembled multi-lavatory system as recited in claim 13, further comprising a plurality of sensors connected to the plurality of solenoids, wherein the sensors detect when a person'"'"'s hands are inserted into one of the sink regions and provide an output signal to the appropriate cooperating solenoid to permit water flow to that sink region.

15. The preassembled multi-lavatory system as recited in claim 14, wherein the shelf includes a top, a bottom and an interior region disposed between the top and the bottom, and the solenoids and the sensors are disposed in said interior region.
