Abstract

ABSTRACT OF THE DISCLOSURE

The present invention is directed toward a toy water gun which is operated by selectively releasing water from a water reservoir pressurized with air. The present invention has a manually operated pump incorporated into the design. As the pump is cycled, water and air is drawn from a water storage tank. Once drawn, the water and air are forced into a pressure reservoir. As the amount of water and air forced into the pressure reservoir increases, the pressure on the water within the pressure reservoir increases. The pressure of the water and air within the pressure reservoir increases with each cycle of the pump, until the pump can no longer overcome the pressure of the water and air within the pressure tank.
The pressurized water and air within the pressure tank has an avenue of release that is regulated by the trigger mechanism of the invention. When no force is applied to the trigger, the pressurized water and air are held at bay with no means of release. When force is applied to the trigger, the water is first released from the pressurized container and is channeled through a narrow nozzle. The escape of the water, under pressure, through the narrow nozzle creates a stream of propelled water that lasts as long as the trigger is engaged or until the air pressure propelling the water equals the ambient pressure.
