Abstract

A water delivery system (10) includes a first component (52) coupled to a fluid transport member (20) and a second component (66) coupled to an aerator (34) for positioning within a faucet spout (26).

Claims

1. A water delivery system in fluid communication with at least one valve, the water delivery system comprising:

a spout including a discharge end;

an aerator for positioning adjacent the discharge end of the spout;

a fluid transport member having a fluid conduit with a first end in fluid communication with the at least one valve and a second end positioned proximate the discharge end of the spout;

a first component coupled to the fluid transport member, the first component including a side wall defining a fluid conduit extending along a longitudinal axis and in fluid communication with the fluid conduit of the fluid transport member, the first component further including at least one guide pin extending radially outwardly from the side wall;

a second component coupled to the aerator, the second component including a side wall defining a bore sealingly receiving the first component and having a channel to receive the at least one guide pin wherein the second component is rotatable relative to the first component between an unlocked position and a locked position, the at least one guide pin being free to move axially within to the channel when in the unlocked position and being restrained from axial movement within to the channel when in the locked position.

2. The water delivery system of claim 1, wherein the channel of the second component includes an axially extending portion and a circumferentially extending portion extending perpendicular to the axially extending portion.

3. The water delivery system of claim 1, further comprising at least one locking tab wherein the side wall of the second component includes a lip configured to engage the at least one locking tab and prevent rotational movement of the second component relative to the first component in a first direction.

4. The water delivery system of claim 1, wherein the first component is an overmold component coupled to the fluid transport member.

5. The water delivery system of claim 1, wherein the second component includes a first set of threads and the aerator includes a second set of threads, the first set of threads and the second set of threads cooperating to couple the aerator to the second component.

6. The water delivery system of claim 1, wherein a seal is positioned between the first component and the second component.

7. The water delivery system of claim 1, wherein the spout member includes a channel for receiving the fluid transport member, the channel including a portion receiving the second component.

8. The water delivery system of claim 7, wherein the second component is held in position relative to the spout by a downwardly facing surface of the spout engaging an upper surface of the second component.

9. The water delivery system of claim 1, wherein the fluid transport member is made of a non-metallic material.

10. The water delivery system of claim 9, wherein the fluid transport member is made of a PEX material.

11. A water delivery system in fluid communication with at least one valve, the water delivery system comprising:

a body defining a longitudinal axis;

a fluid transport member having an end positioned within the body and adapted to be in fluid communication with the at least one valve;

a holder supported by the body and including a fluid conduit having a first end and a second end, the end of the fluid transport member being received in the first end of the holder;

an aerator coupled to the second end of the holder; and

wherein the end of the fluid transport member is held within the fluid conduit of the holder by translating the holder along the longitudinal axis of the body in a first direction and then rotating the holder about the longitudinal axis in a second direction to a locked position, and the end of the fluid transport member is removable from within the fluid conduit of the holder by rotating the holder about the longitudinal axis in a third direction opposite the second direction and translating the holder along the longitudinal axis of the body in a fourth direction opposite the first direction to an unlocked position.

12. The water delivery system of claim 11, wherein the body comprises an overmold component coupled to the first end of the fluid transport member.

13. The water delivery system of claim 12, wherein the body is made of a non-metallic material.

14. The water delivery system of claim 13, wherein the body is made of a PEX material.

15. The water delivery system of claim 11, wherein the fluid transport member is made of a non-metallic material.

16. The water delivery system of claim 15, wherein the fluid transport member is made of a PEX material.

17. The water delivery system of claim 11, wherein the body includes a pair of diametrically opposed guide pins, and the holder includes a pair of diametrically opposed channels configured to receive the guide pins.

18. The water delivery system of claim 17, wherein the body includes a pair of diametrically opposed locking tabs, and the first end of the holder including a pair of lips configured to engage the locking tabs and prevent rotational movement of the holder relative to the body in the third direction.

19. A fluid coupling comprising:

a fluid transport member having a fluid conduit with an end;

a first component formed of a polymer overmolded about the end of the fluid transport member;

a second component including a bore having opposing first and second ends, the first end of the bore sealingly receiving the first component;

an aerator coupled to the second end of the second component; and

a bayonet coupling configured to axially and rotationally secure the first component to the second component.

20. The fluid coupling of claim 19, wherein the first component includes a side wall and at least one guide pin extending radially outwardly from the side wall;

the second component includes a side wall having at least one channel to receive the at least one guide pin, the second component being rotatable relative to the first component between an unlocked position and a locked position, the at least one guide pin being free to move axially relative to the channel when in the unlocked position and being restrained from axial movement relative to the channel when in the locked position.

21. The fluid coupling of claim 20, further comprising at least one locking tab wherein the side wall of the second component includes a lip configured to engage the at least one locking tab and prevent rotational movement of the second component relative to the first component in a first direction.
