Abstract
A toy water shooter may be worn in a concealed manner on a user's forearm, beneath clothing. The shooter includes a pressurizable bladder that may be filled with water and which is plumbed to a trigger-operated nozzle mounted on a wrist support. The bladder may be pressurized by pumping an air bulb, which fluidly communicates with the bladder. The trigger is mounted in a position that allows it to be operated by thumb movement. 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.
