Toy water gun
The present invention provides a simple, inexpensive, and reliable toy water gun configuration for launching a blast of water. For example, the water gun has a reservoir for storing fluid and a nozzle for expelling fluid. A user then propels the water from the reservoir down a neck and towards the nozzle via a motion applied to the entire water gun. The water then exits the gun through the nozzle in a blasting form.
This application is a continuation of U.S. patent application Ser. No. 10/640,509 entitled “TOY WATER GUN,” filed on Aug. 12, 2003 and is incorporated herein by reference.
FIELD OF THE INVENTIONThis invention relates to children entertainment devices, and more particularly, to children entertainment devices such as toy water guns.
BACKGROUND OF THE INVENTIONA variety of water gun devices have been described in the prior art. These devices have configurations ranging from manual piston pumps, which dispel a pump chamber's fluids when compressed, to pressurized systems, which typically use a pumping means to pressurize a water-containing chamber that will later be dispelled. Furthermore, water gun embodiments using electrical pumps have also been described in the prior art.
These configurations have a number of innate problems because of their inherent complexity. The first and most notable of these is the considerable cost associated with the manufacturing of such intricate configurations. The large number of parts and their extensive time of assembly can often lead to substantially higher costs. As a general rule, these configurations' greater number of parts directly leads to greater costs.
In addition, this inherent complexity can also lead to an increased likelihood of mechanical failure. For example, pressurized systems commonly have difficulties with pump jams, part breaks, and the like. Meanwhile, devices relying on electrical pumps can have numerous troubles and reliability issues relating to the electrical motors they depend on. All of these difficulties can significantly reduce the overall quality of use.
Finally, such complexity can augment complexity of use and further detract from the overall enjoyment of the user. For example, pressurized squirt guns often require numerous pumping motions to pressurize the chamber before any water can be dispelled. This activity can be both exhausting and irritating during repeated use. Similarly, devices using electrical power often require new batteries in order to be used. This dependency can be another irritating factor as well as an additional cost associated with such complex configurations.
The water gun prior art is also limited in its capability to issue a broad blast of water. Such a water blast is often preferable because of its dense shooting area and lessened need for aiming—a wide-range blast of water can easily soak a person with one shot. Thus far, the prior art has primarily disclosed configurations for dispelling a stream, often steady, of fluid from a nozzle. However, in many cases, for the previously mentioned reasons, it is preferable to launch a broad, splattering blast of water.
Accordingly, a simple, inexpensive, and reliable water gun configuration that does not require numerous parts or a complicated method of use is desirable. In addition, a water gun that aptly delivers a dense blast of water is as well desirable.
SUMMARY OF THE INVENTIONThe present invention provides a simple, inexpensive, and reliable toy water gun configuration for launching a blast of water. In accordance with an exemplary embodiment of the present invention, water is stored in a reservoir. A user then propels the water from the reservoir down a narrowing neck and towards a nozzle via a motion applied to the entire water gun. The water then exits the gun through the nozzle in a blasting form.
BRIEF DESCRIPTION OF THE DRAWINGSAdditional aspects of the present invention will become evident upon reviewing the non-limiting embodiments described in the specification taken in conjunction with the accompanying figures, wherein like numerals designate like elements, and:
The following descriptions are of preferred exemplary embodiments only, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather the following description provides a convenient illustration for implementing a preferred embodiment of the invention. Various changes may be made in the function and arrangement of elements described in the preferred embodiments without departing from the spirit and scope of the invention as set forth herein.
Generally, in accordance with a preferred embodiment of the present invention, a water gun is provided for releasing a blast of water. The device is suitably configured to make a water blast via a motion applied to the entire water gun. More particularly, the motion creates a momentum in the volume of the fluid of the gun, which in turn may be used to create a pressure differential in the vicinity of a nozzle. For example, in a preferred embodiment, this configuration suitably eliminates the need for integrated pumps and pressurized chambers, and instead allows a user to easily launch a blast of water from a simple device. For example, water may be contained in a reservoir. A user can then propel the water from the reservoir down a narrowing neck and toward a nozzle via a quick forward and backward motion along the device's axis. The water then exits the gun through the nozzle in a blasting form. Thus, it should be appreciated that any number of movements that create a momentum can be used while still falling within the scope of the present invention.
Additionally, in accordance with one aspect of the present invention, the water gun could be suitably configured to additionally possess a controller for regulating the flow of exiting water through the nozzle. For example, a trigger mechanism could be used in combination with the nozzle to provide the user with full control over when water would exit the water gun.
Thus, with reference to
With continuing reference to
In addition, and again in accordance with one aspect of the present exemplary embodiment, pressure normalizer 50 is present as semi-pliable walls of reservoir 20. These semi-pliable walls allow reservoir 20 to cave in slightly with the exiting of fluid 60 through nozzle 40, thereby reducing the overall volume of reservoir 20 and counteracting the resulting vacuum and pressure change. After use, air can than enter reservoir 20 via nozzle 40 and thereby completely neutralize the pressure in reservoir 20, allowing the walls of reservoir 20 to return to their original, uncollapsed positions. However, and in accordance with an alternate embodiment of the invention, pressure normalizer 50 is a one-way valve letting air enter reservoir 20 as fluid 60 exits through nozzle 40, thereby effectively neutralizing vacuums in reservoir 20. Furthermore, neck 30 and reservoir 20 may be covered with an aesthetic housing (not shown). Preferably, such aesthetic housing is translucent so as to let the user view the internal workings of water gun 10.
Water gun 10 is preferably substantially long along its lengthwise axis and substantially narrow along its depth. Preferably, water gun is about 30 inches long and about 1 inch deep, though, in accordance with various alternate embodiments of the present invention, water gun 10 comprises various other dimensions. For example, in other embodiments, water gun 10 has a length of about 20 to about 50 inches is about 0.5 inches to about 1.5 inches deep. Additionally, water gun 10 preferably comprises a fanning height along its length. For example, this height preferably increases to about 5 inches in height from the more narrow height of neck 30 of about 2 inches. Furthermore, in accordance with various alternate embodiments of the present invention, the fanning height may vary.
In use, water in water gun 10 traveling down neck 30 towards nozzle 40 can easily pull in broad, semi-pliable walls of reservoir 20. This configuration has been tested to perform especially well because of the integrated effect produced by the long length, narrow depth, and fanning height. However, again, in accordance with various alternate embodiments of the present invention, water gun 10 could comprise various other configurations.
Thus, in accordance with the present exemplary embodiment of the invention and now in reference to
Now with reference to
In accordance with one aspect of a preferred embodiment of the invention, pressure normalizer 50 is a one-way valve and is present at the top of reservoir 20. One-way valve pressure normalizer 50 lets air enter reservoir 20 and neutralizes the vacuum generated during use as fluid 60 escapes through nozzle 40. Preferably, one-way valve pressure normalizer 50 is resisted so as to minimize unintentional loss of fluid 60 through nozzle 40 by only allowing air to enter reservoir 20 when the pressure within reservoir 20 is substantially less than the outside air pressure (i.e. during a “firing” motion). However, and in accordance with an alternate embodiment of the invention, pressure normalizer 50 is a simple hole so as to effectively neutralize all vacuums in reservoir 20. However, in accordance with various alternate embodiments, pressure normalizer 50 may instead be composed of a combination of holes, pliable reservoir 20 walls, one-way valves, or the like. This “combination” pressure normalizer 50 collectively neutralizes resulting vacuums within reservoir 20.
In accordance with another aspect of a preferred embodiment of the invention, a filling lid 22 is located on an orifice 23 of reservoir 20. Orifice 23 effectively provides an easy means for filling reservoir 20 with a faucet, hose, bucket, or the like. Moreover, filling lid 22 preferably screws tightly on orifice 23 thereby providing an airtight seal. In this embodiment, one-way valve 21 is preferably integrated into filling lid 22. However, and again in accordance with various alternate embodiments, water gun 10 could be further adapted to be used with various “quick-fill” means now known or not yet known for the quick filling of water guns with fluid.
Additionally, and in accordance with another aspect of a preferred embodiment, a rotatable nozzle system 41 lies over basic nozzle 40. Rotatable nozzle system 41 possesses multiple nozzle varieties allowing the user to control the amount of fluid 60 exiting through nozzle 40 during use. For example, nozzle system 41 could possess a small, medium, and large nozzle as well as a nozzle with a collection of three holes (see
In addition, and in accordance with another aspect of a preferred embodiment, a carrying strap 70 is attached to water gun 10 for easier overall transport and use. Carrying strap 70 preferably attaches near end 31 and the end of reservoir 20. Likewise, a handle 80 is integrated into water gun 10 to similarly make overall transport and use easier.
