Abstract

The present invention is a toy water gun which is operated by selectively releasing water from a water reservoir that is pressurized with air. The gun has amanually operated air pump which pressurizes a water reservoir and consequently pressurizes any water therein. The pressurized water has an avenue of release that is regulated by a trigger mechanism. When no force is applied to the trigger, the pressurized water is held at bay with no means of release. When force is applied to the trigger, water is released from the pressurized reservoir and is channeled through a narrow nozzle. The escape of the pressurized water through the narrow nozzle creates a stream of propelled water that lastas as long as the trigger is engaged or until the pressure on the water in the reservoir equals the ambient air pressure. Water is added to the present invention via at least one fill opening on the water reservoir. The reservoir itself is non-detachable from the gun housing. There is an orifice on the water reservoir separate from the fill opening which is connected to the housing and serves as both the entrance point of pressurized air from the air pump, and the exit point of the pressurized water.

Claims20

Dependent claims

A high pressure, self-contained, air pressured toy water gun, which comprises:

(a) a housing;
(b) an extended handle connected to said housing;
(c) a trigger located on said housing adjacent said handle;
(d) a barrel portion of said housing extending outwardly away from said handle;
(e) at least one high pressure, non-detachable water storage reservoir externally attached to said housing, said reservoir having a fill port, and said reservoir having an orifice with connection means connected to said housing;
(f) an attachment means located on said water gun housing for attaching said water storage reservoir to said water gun housing by attachment of said connection means of said orifice to said attachment means, and, when said water storage reservoir is attached to said housing, said attachment means seals said orifice to said housing with a seal impervious to water and air;
(g) a pressurizing means with a slider, operably connected to said reservoir for pressurizing said reservoir with air, said means being an integral part of said water gun housing and being remotely located from said reservoir and said attachment means;
(h) an elongated avenue of release for water displaced by said pressurized air, said avenue of release extending from said attachment means and running the length of said barrel;
(i) a water release means for regulating the fluid flow through said avenue of release, said water release means being operable by said trigger of said water gun and functionally connected to said avenue of release;
and,
(j) a nozzle at the end of said barrel, said nozzle being connected to said avenue of release.
