Abstract
The present invention is an expandable bladder toy water gun. It includes a main housing having a barrel and water ejection nozzle, a handle and a trigger, as well as an inflatable bladder connected to the main housing, the bladder having an inlet and an outlet. There is also a storage tank for supplying water thereto, as well as a hand pump connected to both the storage tank and the bladder. The pump is physically connected to the housing and functionally connected to the storage tank and the bladder inlet. There is a bladder release valve having an upstream side and a downstream side, and it is connected to the bladder outlet at the valve's upstream side, and is connected to the trigger for opening and closing thereof, and is connected to the nozzle at the valve's downstream side for subsequent water ejection when the trigger is pulled.
Claims28
An expandable bladder toy water gun, which comprises:
- (a) a main housing having a barrel, a nozzle, a handle and a trigger located thereon;
- (b) an expandable bladder connected to said main housing, said bladder having an inlet and an outlet;
- (c) a water storage tank connected to said water gun and having an outlet connected to a pump;
- (d) a pump for pumping water from said tank to said bladder to expand and fill said bladder with water, resulting in an expanded bladder, wherein said expanded bladder provides a motive force for ejection of water from said toy water gun, said pump being physically connected to said housing and being functionally connected to said bladder inlet and said tank, said pump having sufficient pumping pressure to expand said bladder upon pumping water thereto, said pump having a one-way valve to permit pumping from said tank to said bladder;
- and,
- (e) a bladder release valve having an upstream side and a downstream side, and being connected to said bladder outlet at said valve's upstream side, and being connected to said trigger for opening and closing thereof, and being functionally connected to a nozzle for ejection of water at said valve's downstream side upon release of at least a portion of said expanded bladder, said valve having a first, closed position to maintain expanded bladder water containment, and a second, open position to effect bladder release.
An expandable bladder toy water gun which comprises:
- (a) a main housing having a barrel, a nozzle, a handle and a trigger located thereon;
- (b) an expandable bladder connected to said main housing, said bladder having an inlet and an outlet;
- (c) a water storage tank connected to said water gun and having an outlet connected to a pump;
- (d) a pump for pumping water from said tank to said bladder to expand and fill said bladder with water, resulting in an expanded bladder, wherein said expanded bladder provides a motive force for ejection of water from said toy water gun, said pump being physically connected to said housing and being functionally connected to said bladder inlet and said tank, said pump having sufficient pumping pressure to expand said bladder upon pumping water thereto, said pump having a one-way valve to permit pumping from said tank to said bladder;
- (e) a bladder release valve having an upstream side and a downstream side, and being connected to said bladder outlet at said valve's upstream side, and being functionally connected to said trigger for opening and closing thereof, and being connected to a nozzle for ejection of water at said valve's downstream side upon release of at least a portion of said expanded bladder, said valve having a first, closed position to maintain expanded bladder water containment, and a second, open position to effect bladder release;
- and,
- (f) said bladder having a predetermined expansion size to which it is capable of being expanded, and an enclosure provided around said bladder, said enclosure being of a size less than said predetermined expansion size to enhance a controlled expansion of said bladder during pumping and filling.
