In an alternate embodiment, the bladder may be worn around the user's waist.
Description




TECHNICAL FIELD




This invention relates generally to toy water shooters, and more particularly to a novelty toy water shooter that may be concealed under the user's clothing.




BACKGROUND OF THE INVENTION




Young people of all ages enjoy water fights with toy water guns. As such, it is not surprising there are many, many different types of water shooters available. These run from simple hand-held squirt guns that use trigger-activated pumps to eject water, to more complicated and sophisticated shooters that rely upon pressurized tanks to shoot a stream of water a significant distance.




A concealed water gun adds an extra dimension of fun to water fights. Among other advantages available when the water gun is hidden, the gun may go unnoticed until it is used to douse its target, and if the shooter is clever enough and the concealment good enough, even after the target has been hit. U.S. Pat. No. 4,997,110 discloses a prior concealed water shooter. While the gun disclosed in the '110 patent may be concealed, it relies upon an electric pump powered by batteries and activated by an electric switch to eject water from the nozzle, and such electrical components add complexity to what is essentially a toy novelty.




There is a need therefore for improved toy water shooters, and in particular, concealable water guns.




SUMMARY




A pressurizable bladder is configured for attachment to a user's arm in a concealed position. The bladder has a refill tube for adding water, and an air inlet that is attached to a hand pump for pressurizing the bladder. A nozzle and valve are fluidly connected to the bladder and a trigger is operable to selectively open and close the valve.




In a second illustrated embodiment the pressure bladder is configured for attachment to the user's waist, and the other components are modified accordingly. The hand pump and bladder-refill tube are connected to the bladder with conduits—the hand pump conduit may be extended from the bladder down the user's sleeve and held in one hand, and the nozzle and trigger are held in the user's other hand.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS




With reference to

FIG. 1

, a water shooter


10


is seen as it may be worn on a user's right arm


12


. As seen in

FIGS. 1 and 2

, water shooter


10


, which at times herein is referred to as a water gun, comprises three basic components, each of which will be described in detail, namely, a hand piece


14


, a wrist piece


16


and an arm piece


18


.




Hand piece


14


is ergonomically designed to fit in the palm area


25


of the user's right hand


22


as shown in FIG.


1


. Of course, the hand piece may be designed just as well to fit in a user's left hand. Hand piece


14


includes a pressure bulb


24


that is preferably rubber and which is connected to a trigger housing


26


, which is preferably a resilient plastic material. A trigger


28


is connected to housing


26


in a position such that the user may activate the trigger with his or her thumb


30


to selectively open and close a valve, as detailed below, to selectively induce or stop a flow of water through a nozzle. Trigger housing


26


and pressure bulb


24


are preferably designed to fit comfortably into the user's palm area


25


, so that the user's hand will be more or less naturally curled around the pressure bulb and the trigger housing


26


and will be less likely, therefore, to reveal the presence of the shooter


10


. More specifically, trigger housing is configured to follow the normal contours of a human hand and includes a formed indentation


32


where the index finger


34


may rest. In addition to providing an ergonomic design, the indentation allows the user to hold onto the hand piece


14


more firmly, even when the hand piece is wet.




Pressure bulb


24


is a flexible air bulb, preferably fabricated of rubber that is fluidly connected to a bladder in arm piece


18


in the manner described below. As best shown in

FIG. 1

, pressure bulb


24


is sized to fit into the user's palm area


25


between the trigger housing and the user's middle finger


36


, ring finger


38


, and little finger


40


, and such that the user's fingers naturally curve around the pressure bulb. The pressure bulb


24


is attached to the trigger housing


26


at the interface therebetween, typically with an adhesive material. Pressure bulb


24


includes an air intake opening


42


that is typically a small hole in the bulb, and which functions to allow air to enter the bulb as it is squeezed to pressurize the bladder.




As noted, pressure bulb


24


is fluidly connected through a conduit


44


to the bladder in the arm piece


18


. With reference to

FIG. 2

, conduit


44


extends through trigger housing


26


and connects to pressure bulb


24


, although the conduit


44


is not shown in

FIG. 2

where it passes through trigger housing


26


. A one-way air valve


46


is interposed in conduit


44


at the point where the conduit enters the bladder. One-way air valve


46


allows air to flow from pressure bulb


24


through conduit


44


in the direction indicated by arrow A, through air valve


46


and into the bladder. Air valve


46


is shown schematically in

FIG. 2

, but will be understood to be any suitable type of one way air valve, and is typically a simple flexible membrane that allows air to flow past the membrane in the direction of arrow A, but which seals against a supporting frame when air pressure forces the membrane in the direction opposite arrow A to prevent backflow.




Trigger


28


is pivotally mounted in trigger housing


26


and is mechanically linked to a water valve


48


so that movement of the trigger from a first, off position, to a second, on position, opens the valve to initiate a flow of water through a nozzle


50


associated with the valve. Trigger


28


is preferably biased into the off position with a suitable biasing device such as a spring, which is not shown. The mechanical linkage between trigger


28


and valve


48


also is not shown, but will be understood to extend internally within trigger housing


26


and is a standard mechanical linkage of any type well known to those of ordinary skill in the art for opening and closing the valve. As detailed below, valve


48


is fluidly connected through a water conduit


52


to the bladder.




Wrist piece


16


serves as a support member for interconnecting the components of hand piece


14


described above with the arm piece


18


and for supporting a water nozzle


50


. Specifically, wrist piece


16


comprises a flexible member


60


that resides on the ventral portion


62


of the user's wrist and is held in place by a strap


64


that is attached to the flexible member


60


and which may be wrapped around the wrist. The opposite ends of the strap


64


may be attached to one another with any appropriate fastener such as hook and loop-type fasteners


66


. The strap


64


is preferably elastic to better secure the strap and the flexible member


10


the wrist, and to accommodate the differing wrist sizes of different users. Nozzle


50


and a water valve


48


, both of which are fluidly connected to a bladder in the arm piece


18


are attached to and supported by the flexible member


60


.




The arm piece


18


will now be described. Arm piece


18


is a multi-layer flexible member that is designed to wrap around a user's forearm


70


in the area generally between the elbow


72


and the wrist


62


. The arm piece includes an outer sheath


74


that is preferably a flexible but resilient and puncture-resistant plastic material that easily and readily accepts printing (so that the arm piece may be emblazoned with logos and the like), and which preferably is water resistant or water proof. Straps


76


and


78


are provided with hook and loop fastener material


80


on opposite ends thereof to allow the sheath


74


to be secured around the user's forearm


70


as shown in FIG.


1


. Referring to

FIG. 3

, a flexible, pressurizable bladder


84


is positioned adjacent the outer sheath


74


on the interior side thereof (“interior” used in reference to the position of the arm piece


18


relative to the user's arm


70


) and is affixed to the outer sheath with a suitable adhesive, or other means. The bladder


84


holds water and air, and is accordingly typically fabricated of a plastic material. The bladder defines a water reservoir for the shooter


10


. Bladder


84


is fluidly connected to air conduit


44


as described above with a one-way air valve


46


, thereby preventing backflow of water and air in conduit


44


. Bladder


84


is also fluidly connected to a refill tube


86


that is positioned on the external portion of sheath


74


, and which includes a watertight cap


88


and which may be secured to outer sheath


74


with a releasable strap


90


.




While in the illustrated embodiment sheath


74


covers only the exterior side of bladder


84


, for added protection and durability the sheath may be enlarged to completely enclose the bladder.




A water supply tube


92


resides internally in bladder


84


and has one end attached to a water conduit


52


and the opposite end free in the interior of the bladder. Water conduit


52


provides a fluid pathway from supply tube


92


into water valve


48


, and thus to nozzle


50


. Nozzle


50


is a standard water nozzle that is attached to and supported by flexible member


60


, and valve


48


is a standard water valve. It is to be understood that the particular type of nozzle and valve is not critical and that there are numerous nozzle/valve combinations that are suitable for use with shooter


10


. Moreover, while water valve


48


and nozzle


50


are described herein as separate components, combination units suitable for use with the present invention may be utilized.




It should be noted that the outer sheath


74


described above provides protection for the underlying bladder


84


to prevent the bladder from punctures. Because the outer surface of the sheath


74


is smooth, the arm piece


18


is easily concealed under a long sleeve shirt. And as described below, the outer sheath


74


also helps pressurize the water in bladder


84


.





FIG. 4

shows the inner side of arm piece


18


—that is, the side of the arm piece that in use rests against the user's arm. It may be seen in this figure that the peripheral dimensions of bladder


84


are slightly smaller than the peripheral dimensions of outer sheath


74


. The bladder


84


is attached to outer sheath


74


in any suitable manner, such as with an adhesive that may be applied to glue zones


82


.




Having described the structure of the embodiment shown in

FIGS. 1 through 4

, the operation of water gun


10


will now be detailed, although operation of the gun is relatively simple and intuitive from the description above. The water gun


10


may be filled and used in any number of ways. One preferred sequence of using the gun follows. The wrist piece


16


or water shooter


10


, with bladder


84


empty is attached to the user's wrist as described above with strap


64


. The user then fills bladder


84


by filling water into the bladder through tube


86


. After the bladder is full, tube


86


is capped off with cap


88


and the tube is secured against outer sheath


74


with strap


90


. Arm piece


18


is then secured to the user's forearm as shown in

FIG. 1

with straps


76


and


78


. The pressure of the straps partially pressurizes the contents of the bladder.




Alternately, the user may begin with the shooter


10


completely removed from the arm, and by filling bladder


84


to capacity with water through refill tube


86


. The refill tube


86


is then sealed off with cap


88


and the tube is secured to outer sheath


74


as shown in

FIG. 1

with strap


90


. The water shooter


10


is then placed around the user's forearm


70


with arm piece


18


on the forearm in the position shown in FIG.


1


. The arm piece is then secured snuggly in place with straps


76


,


78


. The wrist piece


16


is next secured to the wrist, as shown, by attaching the opposite ends of strap


64


. Wrist piece


16


supports the nozzle


50


, and may thus be secured snuggly onto the wearer's wrist.




In either case, and regardless of the sequence that a particular user relies upon, the arm piece should be worn in a position on the forearm such that the hand piece


14


fits snuggly into the user's palm area


25


, as shown. When straps


76


,


78


are secured to the outer sheath the water contained in bladder


84


is pressurized to some degree. With the shooter


10


strapped to the user's arm, the bladder is further pressurized by the user repetitively pumping pressure bulb


24


with three fingers, middle finger


36


, ring finger


38


, and little finger


40


. As the pressure bulb


24


is pumped, air is drawn into the pressure bulb through air intake opening


42


and is forced under pressure into conduit


44


(in the direction of arrows A), through one-way air valve


46


and into bladder


84


. As air enters bladder


84


in this manner, the pressure in the bladder increases. Because air and water in the bladder cannot flow backwardly through air valve


46


, the bladder is quickly pressurized to an internal pressure that is greater than atmospheric pressure.




With bladder


84


filled and pressurized, the user may induce a flow of water through nozzle


50


by moving trigger


28


from the off position to the on position. When the trigger is thus moved, the mechanical linkage linking the trigger to water valve


48


is activated to open the valve, thereby inducing a flow of water through the nozzle. The user can aim the nozzle to direct the spray of water emitted from it onto a desired target. The pressure in bladder


84


provides the energy needed to force water through nozzle


50


. The bladder


84


may be pressurized at any time, even with water valve


48


open, by the user continually pumping pressure bulb


24


as described above.




It will be appreciated that a user may easily conceal the water gun


10


under a long sleeve shirt, even one that is fairly tightly fitting since the components of gun


10


conform relatively closely to the user's arm.




An alternative embodiment of a water gun


100


embodying the principles of the invention is shown in FIG.


5


. Relying in part on the foregoing description and on the illustrations of

FIGS. 1-4

it will readily be appreciated how the embodiment of water gun


100


is built and functions. Thus, the arm piece


18


of

FIGS. 1-4

has been replaced with a waist piece


102


, which includes and outer sheath


104


, and a bladder contained internally in the waist piece in the same manner as described above with respect to arm piece


18


, and includes a bladder refill tube


103


. A pressure bulb


106


is fluidly connected to the bladder by way of an air conduit


108


, which includes a one-way air valve to prevent backflow. Air conduit


108


may be run, for example, under a user's shirt and down a sleeve for concealment. A wrist piece


110


is worn around the user's wrist and includes a nozzle


112


fluidly connected to a water valve


114


, which is activated by a trigger


118


. Water is routed from the bladder in waist piece


102


through a water tube


116


, which like air conduit


108


may be hidden along the wearer's arm under the sleeve of a shirt. Other structural details of the invention illustrated in

FIG. 5

will be readily understood from the foregoing description of the invention of

FIGS. 1-4

.




Having here described illustrated embodiments of the invention, it is anticipated that those of ordinary skill in the art may make other modifications thereto within the scope of the invention. It will thus be appreciated and understood that the spirit and scope of the invention is not limited to those embodiments, but extend to the various modifications and equivalents as defined in the appended claims.
