Abstract

A hose nozzle allowing one hand control for water stream pattern and flow rate is disclosed. The hose nozzle has a tubular body having a connector end for mating with the connector end of a hose. A hand grip having a plurality of finger notches is located around the tubular body. The hand grip allows the nozzle to be held between a user'"'"'s fingers and palm. An outer sleeve member and an annular beveled collar are located in sufficient proximity to the hand grip to allow manual actuation by a user'"'"'s index finger and thumb. The outer sleeve member and the annular collar may be extended or retracted by rotation. The outer sleeve member has a closed end wall with an aperture. An inner stem is located within the outer sleeve and is in fluid communication with the tubular body. The inner stem has an orifice which allows water to flow out of the inner stem and through the aperture when the outer cylinder is extended. Water flow is controlled by rotating the annular collar to permit water to flow through the tubular body, the inner stem, orifice and out of the aperture of the outer sleeve member.

Claims

1. A hose nozzle for use with a hose having one end connected to a fluid source and an opposite connector end, the hose nozzle comprising:

a hollow body having a connector end mateable with the connector end of the hose and a hand grip shaped to fit a user'"'"'s hand;

a fluid flow pattern varying assembly in sufficient proximity to the hollow body to allow manual actuation by the index finger and thumb of the user'"'"'s hand wherein said fluid flow pattern varying assembly has a symmetrical cross section and a longitudinal axis perpendicular to said cross section;

an outlet member coupled to the fluid flow pattern varying assembly and the hollow body which permits fluid flow on the manual actuation of the fluid flow pattern varying assembly; and

a fluid passage extending through the hollow body permitting fluid to flow from the hose to the outlet member parallel to said longitudinal axis.

2. The nozzle of claim 1 wherein the hand grip is a resilient and soft material.

3. The nozzle of claim 2 wherein the hand grip is an elastomeric polymer.

4. The nozzle of claim 1 wherein the hand grip is rubber.

5. The nozzle of claim 1 wherein the hollow body is rigid plastic.

6. The nozzle of claim 1 wherein the hand grip has a top surface allowing the placement of a user'"'"'s palm and a bottom surface with three finger notches.

7. The nozzle of claim 1 wherein the hollow body is bent at an angle relative to the outlet member allowing the water flow to be directed by a user'"'"'s wrist when the user'"'"'s arm is in a substantially vertical position.

8. The nozzle of claim 1 wherein the fluid flow pattern varying assembly includes an outer sleeve member and an annular collar fixedly attached circumferentially around the outer sleeve member.

9. The nozzle of claim 8 wherein the annular collar has a beveled exterior surface having ridges to permit gripping by the user'"'"'s thumb and index finger.

10. The nozzle of claim 8 wherein the outlet member includes an inner stem member having a hollow area with fluid access to the fluid passage, further having a threaded exterior portion and an orifice allowing fluid passage through the inner stem member, wherein the inner stem member is located inside the outer sleeve member;

and

wherein the outer sleeve member has a threaded interior surface which meshes with the threaded exterior surface allowing the outer sleeve member and the annular collar to be extended or retracted by rotating the outer sleeve member in relation to the inner stem member.

11. The nozzle of claim 10 wherein the inner stem member includes a beveled cylinder having a cap, the beveled cylinder being located opposite the exterior threaded surface;

and

wherein the outer sleeve member has an end wall with an aperture with sufficient diameter for partial insertion of the beveled cylinder; and

wherein a cavity is formed between the inner stem and outer sleeve members with fluid access through the orifice in the inner stem member.

12. The nozzle of claim 10 wherein the inner stem and outer sleeve members are brass.

13. The nozzle of claim 8 wherein the annular collar is plastic.

14. A hose nozzle for controlling and varying a water stream from a hose having one end fluidly coupled to a pressurized water source and an opposite open end, the hose nozzle comprising:

a generally tubular body having a connector end coupled to the opposite open end of the hose, the tubular body having an interior cylindrical passage permitting flow of water from the hose through the tubular body and an exterior hand grip;

an inner stem member coupled to the opposite end of the tubular body from the connector end, the inner stem member having one open end permitting passage of water therethrough, an opposite closed end, and an orifice permitting passage of water therethrough proximate the opposite closed end, the inner stem member having a beveled cylinder on the closed end and a threaded exterior surface proximate the open end;

an outer sleeve member having an open end with a threaded interior surface intermeshed with the threaded exterior surface of the inner stem member permitting the outer sleeve member to be retracted or extended in relation to the inner stem member by rotation about the inner stem member, the outer sleeve member having an end wall opposite the open end with an aperture with a sufficient diameter to allow the passage of a portion of the beveled cylinder; and

wherein the hand grip is shaped to allow a user'"'"'s hand to hold the tubular body and rotate the outer sleeve member.

15. The hose nozzle of claim 14 further comprising an annular collar attached to at least a portion of the exterior surface of the outer sleeve member.

16. The hose nozzle of claim 15 wherein the annular collar has a beveled exterior surface and permits a user'"'"'s index finger and thumb to rotate the annular collar.

17. The nozzle of claim 14 wherein a cap is attached to the beveled cylinder on the end opposite the end attached to the open end of the inner stem.

18. The hose nozzle of claim 14 wherein the hand grip has a bottom surface with a plurality of finger notches and a top surface shaped to allow placement of a user'"'"'s palm.

19. The nozzle of claim 18 wherein the hand grip is an elastomeric polymer.

20. The nozzle of claim 18 wherein the hand grip is rubber.

21. The nozzle of claim 14 wherein the tubular body is bent at an angle relative to the inner stem and outer sleeve members allowing the water flow to be directed by a user'"'"'s wrist when the user'"'"'s arm is in a substantially vertical position.

22. The hose nozzle of claim 14 wherein the inner stem and outer sleeve members are brass.
