Abstract

A faucet spray head includes a diverter valve that has a diverter stem constructed and arranged to control water flow patterns. The stem includes a neck and a head that is larger than the neck. A shell encloses the diverter valve, and the shell has an opening through which the stem extends. A pivot member is coupled to the shell, and a rocker arm is pivotally coupled to the pivot member. The rocker arm has a retention opening, and the retention opening is adapted to slidably receive and retain the head of the stem during assembly of the rocker arm to the pivot member.
The rocker arm is attached to the diverter valve in order to actuate the valve.
The spray head includes lock pins that are configured to engage a lock insert that is secured to a spout.

Claims (20)

1. An apparatus, comprising:
a faucet spray head including a diverter valve having a diverter stem constructed and arranged to control water flow patterns from said faucet spray head, said stem including a neck and a head that is larger than said neck, a shell enclosing the diverter valve, said shell having an opening through which said stem extends, a pivot member coupled to said shell, and a rocker arm pivotally coupled to said pivot member, said rocker arm having a retention opening, said retention opening being constructed and arranged to slidably receive and retain said head of said stem during assembly of said rocker arm to said pivot member.
2. The apparatus of claim 1, wherein said pivot member and said shell are separate components.
3. The apparatus of claim 2, wherein:
said shell defines a pair of lock tab openings; and said pivot member has a pair of lock tab arms engaged in said lock tab openings.
4. The apparatus of claim 1, wherein said shell includes a rocker arm flange surrounding said rocker arm to minimize tampering with said rocker arm.
5. The apparatus of claim 1, wherein said retention opening of said rocker arm includes an insertion portion sized to receive said head of said stem and a retention portion with retention ridges spaced apart to retain said head of said stem between said retention ridges.
6. The apparatus of claim 1, further comprising:
one or more lock pins extending from said spray head;
a spout; and a lock insert received in said spout, wherein said lock insert includes a lock pin socket constructed and arranged to receive and hold said lock pins of said spray head.
7. The apparatus of claim 6, wherein:
said spout defines a lock tab opening and an orientation notch; and said lock insert includes a lock tab coupled in said lock tab opening and an alignment tab received in said orientation notch.
8. The apparatus of claim 6, wherein said lock pin socket includes one or more lock pin openings having a bayonet shape.
9. The apparatus of claim 6, wherein said lock pin socket includes one or more lock pin openings configured for straight in and out docking of said faucet spray head.
10. An apparatus, comprising:
a spout defining a spout opening and a lock tab opening;
a supply hose slidably received in said spout opening;
a spray head coupled to said hose, said spray head having at least one lock pin;
and a lock insert received in said spout, said lock insert having a lock tab received in lock tab opening to secure said lock insert to said spout, said lock insert defining at least one lock pin opening constructed and arranged to detachably retain said lock pin of said spray head.
11. The apparatus of claim 10, wherein said lock pin opening has a bayonet shape.
12. The apparatus of claim 10, wherein lock insert includes a pair of lock arms that define said lock pin opening, said lock arms each having a retention flange that retains said lock pin in said lock pin opening.
13. The apparatus of claim 10, wherein:
said spout defines an orientation notch; and said lock insert includes an alignment tab received in said orientation notch to minimize rotation of said lock insert.
14. The apparatus of claim 13, wherein said lock pin opening has a bayonet shape.
15. The apparatus of claim 13, wherein lock insert includes a pair of lock arms that define said lock pin opening, said lock arms each having a retention flange that retains said lock pin in said lock pin opening.
16. The apparatus of claim 15, wherein said lock insert defines a retention flange to prevent said lock insert from being pushed further inside said spout during docking of said spray head.
17. The apparatus of claim 10, wherein said spray head includes:
a diverter valve having a diverter stem constructed and arranged to control water flow patterns from said spray head, said stem including a neck and a head that is larger than said neck;
a shell enclosing the diverter valve, said shell having an opening through which said stem extends;
a pivot member coupled to said shell; and a rocker arm pivotally coupled to said pivot member, said rocker arm having a retention opening, said retention opening being constructed and arranged to slidably receive and retain said head of said stem during assembly of said rocker arm to said pivot member.
18. A method of assembling a spray head, comprising:
attaching a pivot member to a spray head shell, the spray head shell having a diverter stem of a diverter valve extending therefrom, the stem including a neck and a head that is larger than the neck;
positioning a head opening defined in a rocker arm over the head of the diverter stem, the rocker arm having a retention opening proximal the head opening, the retention opening having a pair of retention flanges that define a gap that is larger than the neck and smaller than the head of the diverter stem;
securing the rocker arm to the diverter stem by sliding the neck of the diverter stem between the retention flanges; and mounting the rocker arm on the pivot member by pivotally securing the rocker arm to the pivot member.
19. The method of claim 18, wherein:
the pivot member includes a pair of lock tabs;
the spray head shell defines a pair of lock tab openings; and said attaching the pivot member includes locking the lock tabs of the pivot member into the lock tab openings.
20. The method of claim 19, wherein:
the pivot member has one or more pivot pins;
the rocker arm defines one or more pivot pin openings; and said mounting the rocker arm includes securing the pivot pins in the pivot pin openings.
