Magnetic coupling for sprayheads

1. A faucet comprising:

a supply hose adapted to supply water;

a faucet head fluidly coupled to the supply hose and adapted to dispense the water;

a faucet spout receiving the supply hose and adapted to support the faucet head;

a magnetic coupling to removably couple the faucet head to the faucet spout, the magnetic coupling including a first member supported for movement with the faucet head, and a second member supported by the faucet spout, at least one of the first member and the second member including a magnet, wherein the magnetic coupling requires between 2.0 and 12.0 pounds of force to pull the faucet head from the faucet spout; wherein:

the faucet head includes a user input and a valve controlled by the user input;

the first member includes a first magnet including multiple magnetic fields;

the second member includes a second magnet including multiple fields; and

at least one of the multiple magnetic fields of each of the first magnet and the second magnet is oriented in a first direction, and at least one of the multiple magnetic fields of each of the first magnet and the second magnet is oriented in second direction, the second direction is substantially opposite the first direction, such that the magnetic coupling exhibits alternate attracting and repelling modes of operation, and the magnetic coupling rotationally orients the faucet head relative to the delivery spout for locating the user input for a user.

2. The faucet of claim 1 , wherein the magnet has a magnetic field of between 400 and 2,000 gauss tested at 0.090 inches.

3. The faucet of claim 1 , wherein at least one of the first member and the second member includes an attracted member magnetically attracted to the magnet.

4. The faucet of claim 3 , wherein the first member includes the attracted member, and the second member includes the magnet.

5. The faucet of claim 3 , wherein the first member includes the magnet, and the second member includes the attracted member.

6. The faucet of claim 1 , wherein the magnetic coupling includes a coupling surface having an area of between 0.4 and 2.0 inches.

7. The faucet of claim 1 , wherein the magnet is at least partially overmolded with a polymer, the polymer being formed into a connector adapted to couple the magnet to one of the faucet head and the faucet spout.

8. The faucet of claim 1 , wherein the magnetic coupling further includes a backing member configured to increase a magnetic flux of the magnet.

9. The faucet of claim 1 , wherein the user input is a lever.

10. A faucet comprising:

a supply hose adapted to supply water;

a faucet head fluidly coupled to the supply hose and including a user input and a valve, the valve adapted to control the dispensing of water upon activation of the user input;

a faucet body adapted to support the faucet head and including a delivery spout, such that the faucet head extends from the faucet body;

a magnetic coupling to removably couple the faucet head to the faucet body, the magnetic coupling including a first member supported by the faucet head, and a second member supported by the faucet body, at least one of the first member and the second member including a magnet; and

cooperating orientation members to rotationally orient the faucet head relative to the delivery spout for locating the user input for a user.

11. The faucet of claim 10 , wherein the magnetic coupling requires between 2.0 and 12.0 pounds of force to pull the faucet head from the faucet spout.

12. The faucet of claim 11 , wherein the magnet has a magnetic field of between 400 and 2,000 gauss tested at 0.090 inches.

13. The faucet of claim 10 , wherein at least one of the first member and the second member includes an attracted member magnetically attracted to the magnet.

14. The faucet of claim 13 , wherein the first member includes the attracted member, and the second member includes the magnet.

15. The faucet of claim 13 , wherein the first member includes the magnet, and the second member includes the attracted member.

16. The faucet of claim 10 , wherein the magnetic coupling includes a coupling surface having an area of between 0.4 and 2.0 inches.

17. The faucet of claim 10 , wherein the magnet is at least partially overmolded with a polymer, the polymer being formed into a connector adapted to couple the magnet to one of the faucet head and the faucet spout.

18. The faucet of claim 10 , wherein the magnetic coupling further includes a backing member configured to increase a magnetic flux of the magnet.

19. The faucet of claim 10 , wherein the user input is a lever.

20. The faucet of claim 10 , wherein the cooperating orientation members comprise the first member and the second member of the magnetic coupling.

21. The faucet of claim 20 , wherein:

the first member includes a first magnet including multiple magnetic fields;

the second member includes a second magnet including multiple magnetic fields; and

at least one of the multiple magnetic fields of each of the first magnet and the second magnet is oriented in a first direction, and at least one of the multiple magnetic fields of each of the first magnet and the second magnet is oriented in second direction, the second direction is substantially opposite the first direction, such that the magnetic coupling exhibits alternate attracting and repelling modes of operation, and the magnetic coupling rotationally orients the faucet head relative to the delivery spout for locating the user input for a user.
