Abstract

A method of installing a sprayhead retraction assembly includes providing a portion of a hose in a groove defined by a first pulley, and coupling a first end of a constant-force spring to a first surface. The method further includes coupling a second end of the constant-force spring to a second pulley, and coiling the constant-force spring around the second pulley, wherein the second pulley is coupled to and offset from the first pulley.

First claim

What is claimed is:

1. A method of installing a sprayhead retraction assembly comprising:
providing a portion of a hose in a groove defined by a first pulley;
coupling a first end of a constant-force spring to a first surface;
coupling a second end of the constant-force spring to a second pulley; and
coiling the constant-force spring around the second pulley, wherein the second pulley is coupled to and offset from the first pulley.

2. The method of claim 1 , further comprising providing a portion of the hose in a groove defined by a third pulley, wherein the third pulley is configured to redirect the hose between a sprayhead disposed at an outlet end of the hose and the first pulley.

3. The method of claim 2 , further comprising providing a portion of the hose in a groove defined by a redirecting member, wherein the redirecting member is configured to redirect the hose between a valve disposed at an inlet end of the hose and the first pulley.

4. The method of claim 1 , further comprising feeding the hose through a second surface, the second surface configured to have a sprayhead mounted thereon.

5. The method of claim 4 , wherein feeding the hose through the second surface further comprises:
feeding a first end of the hose through the second surface; and
feeding a second end of the hose through the second surface.

6. The method of claim 5 , further comprising fluidly coupling the first end of the hose to a valve; and
fluidly coupling the second end of the hose to a sprayhead.

7. A method of installing a sprayhead retraction assembly comprising:
coupling a first end of a constant-force spring to a surface;
coupling a second end of the constant-force spring to a first pulley;
coiling the constant-force spring around the first pulley; and
engaging a hose with the first pulley.

8. The method of claim 7 , wherein the first pulley engages the hose through a first member.

9. The method of claim 8 , further comprising engaging the hose with a second pulley;
wherein the second pulley is coupled to the first member.

10. The method of claim 7 , further comprising providing a first member comprising a first projection extending perpendicularly from the first member; and
coupling the first pulley to the first projection.

11. The method of claim 10 , further comprising providing a second member defining a first opening configured to receive the first projection therein.

12. The method of claim 11 , further comprising providing the first projection in the first opening with an interference fit.

13. The method of claim 7 , further comprising providing a first member comprising first and second projections extending perpendicularly from the first member;
coupling the first pulley to the first projection;
coupling a second pulley to the second projection; and
providing a portion of the hose in a groove of the second pulley.

14. The method of claim 13 , further comprising coupling a second member to at least one of the first or second projections;
wherein the hose is provided in the groove of the second pulley before the second member is coupled to the first member.

15. The method of claim 13 , further comprising providing a second member defining a first opening configured to receive the first projection therein and a second opening configured to receive the second projection therein.

16. The method of claim 15 , further comprising providing at least one of the first projection in the first opening or the second projection in the second opening with an interference fit.

17. The method of claim 7 , further comprising coupling a first end of the hose to a faucet sprayhead;
coupling a second end of the hose to a water source; and
moving the faucet sprayhead toward a spout as the constant-force spring is coiled.

18. A method of installing a sprayhead retraction assembly comprising:
coupling a first pulley to a surface;
coupling a first end of a constant-force spring to the first pulley;
coupling a second end of the constant-force spring to a first member;
engaging a hose with the first member; and
coiling the constant-force spring around the first pulley.

19. The method of claim 18 , wherein the first member engages the hose through a second pulley.

20. The method of claim 18 , further comprising coupling a first end of the hose to a faucet sprayhead;
coupling a second end of the hose to a water source; and
moving the faucet sprayhead toward a spout as the constant-force spring is coiled.
