Abstract

A fluid pumping device is disclosed. The fluid pumping device includes a housing having a front end and a rear end, a fluid discharge opening in the front end of the housing, a pump assembly, a crank assembly rotatably connected to the pump assembly wherein the crank assembly operates the pump assembly, and a fluid storage reservoir connected to the gear housing from which fluid is drawn into the gear housing to be pumped through the fluid discharge opening.

First claim

What is claimed is:

1. A fluid pumping device comprising:
a housing having a top;
a fluid discharge opening in the housing;
a pump assembly;
a fluid storage reservoir connected to the pump assembly;
a fluid path connected to the fluid storage reservoir and the fluid discharge opening; and
a plurality of nozzles on the top of the housing wherein the nozzles are not fluidly connected to the fluid path and wherein the plurality of nozzles configured to be placed over the fluid discharge opening.

2. The fluid pumping device of claim 1 wherein the pump assembly comprising:
a first gear; and
a second gear, wherein the first gear is larger in diameter than the second gear and wherein the gear ratio between the first gear and the second gear is 15:1.

3. The fluid pumping device of claim 1 further comprising a crank assembly rotatably connected to the pump assembly wherein the crank assembly operates the pump assembly.

4. The fluid pumping device of claim 1 wherein the crank assembly further comprising:
a crank arm; and
a crank handle connected to the crank arm.

5. The fluid pumping device of claim 4 wherein the crank arm further comprising at least one notch and wherein the crank handle may be connected to the crank arm through the at least one notch.

6. The fluid pumping device of claim 5 wherein the crank arm further comprising at least two notches and wherein the crank handle may be connected to the crank arm through any one of the at least two notches whereby the length of the crank arm is determined by the position of the crank handle.

7. The fluid pumping device of claim 1 further comprising at least two removable nozzles, each nozzle having a different diameter opening.

8. The fluid pumping device of claim 7 wherein the at least two removable nozzles are stored on the device housing.

9. The fluid pumping device of claim 1 wherein the pump assembly comprising at least one pair of gears, wherein each pair of gears having a large gear and a pinion gear.

10. The fluid pumping device of claim 9 wherein the gear at least one pair of gears having a gear ratio of 4:1.

11. A toy water gun comprising:
a housing having a front end and a top;
a fluid discharge opening in the front end of the housing;
at least one removable nozzle removably attached to the fluid discharge opening in the front end of the housing;
a fluid storage reservoir;
a fluid path connected to the fluid storage reservoir and the fluid discharge opening; and
a plurality of nozzles on the top of the housing wherein the nozzles are not fluidly connected to the fluid path and wherein the plurality of nozzles configured to be placed over the fluid discharge opening.

12. The toy water gun of claim 11 wherein the gear at least one pair of gears having a gear ratio of 4:1.

13. The toy water gun of claim 11 wherein the gear ratio between the at least one pair of gears 15:1.

14. The fluid pumping device of claim 11 further comprising a crank assembly rotatably connected to the pump assembly wherein the crank assembly operates the pump assembly.

15. The toy water gun of claim 11 wherein the crank assembly further comprising:
a crank arm; and
a crank handle connected to the crank arm.

16. The toy water gun of claim 15 wherein the crank arm further comprising at least one notch and wherein the crank handle may be connected to the crank arm through the at least one notch.

17. The toy water gun of claim 16 wherein the crank arm further comprising at least two notches and wherein the crank handle may be connected to the crank arm through any one of the at least two notches whereby the length of the crank arm is determined by the position of the crank handle.

18. The toy water gun of claim 11 further comprising at least two removable nozzles, each nozzle having a different diameter opening.

19. The toy water gun of claim 18 wherein the at least two removable nozzles are stored on the device housing.

20. The toy water gun of claim 11 further comprising a pump assembly.
