Description
[0001] The present invention relates generally to a devices for
launching a liquid projectile and to targets made of
liquid-reactive substances, and to sets of such devices and
targets.
[0002] Devices which simulate weapons, or which can be used to
simulate combat, are perennially popular. Typically, such devices
produce sounds which indicate when the simulated weapon is being
fired. Devices simulating weapons were then devised which consisted
of a light-projecting mechanism. Such devices were sold with a
light-detecting mechanism that could be worn on the body, which
emitted sound or light when hit by light projected from an
opponent's weapon. However, consumers typically preferred that the
simulated weapons actually shoot a projectile with sufficient force
to strike an opponent or other target. Unfortunately, confusion or
disputes often arose during game play concerning whether a player
has actually been struck by a projectile.
[0003] Sophisticated air- or gas-driven paintball guns are now
available, which forcefully project ammunition consisting of a
hollow ball filled with paint or dye. The balls burst on impact,
leaving no doubt as to whether a target or individual has been
struck. These paintball guns, ammunition and related gear are
generally expensive. Moreover, the paintballs launched by such guns
can be dangerous, requiring protective gear to be worn by
individuals during play. The paintballs also produce messy paint
splatters on impact, both on individuals playing the game as well
as in the game-playing area. Thus, paintball guns are expensive to
acquire and maintain, and are not suitable for children.
[0004] What is needed, therefore, is device or set of devices
simulating weapons or combat, which launch a projectile with
sufficient force to strike an opponent but which will not cause
injuries or produce an inordinate mess. The device or set of
devices would include a means for indicating whether an individual
or target has been struck by a projectile. Such a device would
desirably be inexpensive to acquire and operate.
[0005] Liquid projectiles can be launched from devices which
simulate weapons with sufficient velocity to strike an opponent,
but without causing injury. Liquid reactive materials can be worn
by individuals playing a game, or can comprise part of a
target.
[0006] The invention thus provides a set comprising at least one
first device comprising at least one liquid reservoir and at least
one liquid projectile launching mechanism in fluid communication
with the fluid reservoir. When actuated by the user, the liquid
projectile launching mechanism draws a portion of the liquid from
the reservoir and launches this portion of liquid outward from the
device. The first device may be designed to be carried by a user or
otherwise supported by a user's body. The set further comprises at
least one second device comprising a liquid reactive material.
[0007] The set of the invention can be provided as a kit or a game,
comprising at least two first devices and at least two second
devices of the invention, and optionally instructions for use or
rules for game play.
[0008] The invention further provides a method of playing a game,
comprising the steps of providing at least a first device of the
invention and at least one second device of the invention, and
firing liquid projectiles from the first device toward the second
device, such that the second device can be struck by the liquid
projectiles. The step of firing liquid projectiles can optionally
be repeated until the game is concluded.
[0009] The invention yet further provides a method of marketing a
set of devices, kit or game of the invention, comprising packaging
the set of devices, kit or game with at least one additional
item.
[0010] For the purpose of illustrating the invention, there are
shown in the drawings forms which are exemplary; it being
understood, that this invention is not limited to the precise
arrangements and instrumentalities shown.
[0011] FIG. 1 is an exemplary liquid projectile launching device of
the invention.
[0012] It will be appreciated that the following description is
exemplary and is not intended to define or limit the invention,
other than in the appended claims.
[0013] A first device of the invention comprises a body which can
support at least one liquid reservoir and at least one liquid
projectile launching mechanism. The body can be made in any
suitable size and shape capable of supporting the liquid reservoir
and liquid projectile launching mechanism, for example in the shape
of a gun or other hand-held or free-standing weapon. The body can
also comprise appendages or other attachments which may move
independently of the body or other components of the first
device.
[0014] Thus, the first device can simulate a gun; e.g., handgun or
pistol, rifle, shotgun, machine gun or machine pistol, archaic
firearms such as flintlocks, matchlocks, blunderbusses and the
like, and archaic projectile weapons such as bows, crossbows,
slings and slingshots and the like. The first device can also
simulate a free-standing or mobile weapon; e.g., a cannon or
carronade, mortar, howitzer, or other artillery piece; or other
more archaic projectile-throwing siege engines such as onagers,
mangonels, trebuchets, ballistae or other catapults; tanks; mobile
guns, and the like.
[0015] The first device can comprise one or more colors, designs or
indicia, for example for the purpose of decoration or to indicate
different group affiliations. Such colors, designs or indicia can
be those associated with actual armies, sports teams or sports or
military figures.
[0016] The first device can be any suitable size which allows a
person to handle the device and actuate the liquid projectile
launching mechanism, as can be readily determined by one skilled in
the art. For example, the device can be from about 10 cm to about
1000 cm (e.g., about 50 cm to about 700 cm, about 150 cm to about
400 cm, or about 250 cm) in length (i.e., from left to right
sides), from about 5 cm to about 500 cm (e.g., about 50 cm to about
250 cm, or about 100 cm to about 150 cm) in height, and from about
5 cm to about 25 cm (e.g., about 10 cm to about 20 cm, or about 15
cm) in depth (i.e., from front to back). Greater or lesser values
are contemplated for the height, length and breadth of the first
device.
[0017] All or part of the first device can be fabricated from any
suitably rigid material, such as heavy gauge paper or cardboard,
woods, metals, plastics, rubbers or synthetic resins, as are known
in the art, by standard techniques for producing devices simulating
weapons and the like. For example, the first device can be
fabricated by injection molding or other suitable technique from
commercially-available material such as thermo plastic polyurethane
(TPU); ionomer resin; ethylene vinyl acetate (EVA); thermo plastic
styrenics (TPS); melt processable rubber (MPR); thermo plastic
vulcanate (TPV); thermo plastic olefin (TPO); thermo plastic ester
elastomer (TPEE); thermo plastic elastomer (TPE); thermoplastic
rubber (TPR); polypropylene (PP), polyethylene terphthalate (PET),
polyvinyl chloride (PVC), acrylonitrile-butadiene-styrene
terpolymer (ABS); a polycarbonate and
acrylonitrile-butadiene-styrene terpolymer blend (PC/ABS); flexible
plastic such as polystyrene sheet or polymethylmethacrylate (PMMA,
marketed as "PERSPEX" by ICI Acrylics, Inc.); other acrylics; metal
(e.g., stainless steel, aluminum, copper); wood; or any combination
thereof. Other suitable materials and forming methods will be
apparent to those skilled in the art.
[0018] The first device may be supplied fully assembled or as a
kit, wherein a user assembles the first device by popping out
prefabricated parts along lines of weakness from a flat piece of
plastic, metal or any other suitable material, and then attaches
the liquid projectile reservoir and liquid projectile launching
mechanism. Generally, the assembly of the device will not require
the aid of tools and/or adhesives, and all the parts can be joined
together by the snap-fit of the parts themselves.
[0019] The liquid reservoir can comprise any closed or open
container suitable for holding liquid. For example, the liquid
reservoir can comprise a thin-walled plastic container with a
removable cap. In practice, the liquid reservoir can be refilled
when the liquid has been depleted during play. Alternatively, the
liquid reservoir may not include a removable cap or other means for
refilling, and the first device or the liquid reservoir would then
be discarded when the liquid in the reservoir is depleted, and the
entire first device or the liquid reservoir replaced. (It is
envisioned that such a liquid reservoir could be disposable, or
provided in a small, inexpensive disposable first device.) The
liquid reservoir can be constructed from any suitable material,
such as the materials described above for the body, according to
techniques within the skill in the art. The liquid reservoir can
also be constructed to withstand internal pressure, for example if
the air and liquid within the reservoir are pressurized in
preparation for firing liquid projectiles. The liquid reservoir can
be supported by the body. As used herein, "supported by the body"
means that the liquid reservoir can be located on the outside of
the body, inside the body, or can extend through the body. It is
specifically contemplated that the liquid reservoir can be
coextensive with the body; for example, the liquid reservoir can be
formed by the body, and this configuration is included in the
meaning of "supported by the body".
[0020] At least one liquid projectile launching mechanism is in
fluid communication with one or more liquid reservoirs, for example
through a tube or other suitable conduit. A liquid projectile
launching mechanism can be supported by the body. As used herein,
"supported by the body" means that the liquid projectile launching
mechanism can be located on the outside of the body, inside the
body, or can extend through the body. When located outside the
body, the liquid projectile launching mechanism can function
independently of the body, and can comprise all the elements
(including a liquid reservoir) necessary to store and launch a
liquid projectile. Such independently functioning liquid projectile
launching mechanisms can be interchangeable from device to device.
Alternatively, the liquid projectile launching mechanism and the
liquid reservoir can be located separately outside the body, and
can be removed or interchanged with the liquid projectile launching
mechanism or liquid reservoirs on other devices. The liquid
projectile launching mechanism can also be located in the body, and
the liquid reservoir can be separate; for example, when the first
device simulates a gun, and the liquid reservoir can be carried on
a belt or back-pack. In any case, that portion of the liquid
projectile launching mechanism which discharges and directs the
liquid projectile away from the body (called the "discharge tube,"
see below) should not be obstructed by the body so that the liquid
projectile can be launched unimpeded.
[0021] The liquid projectile launching mechanism can comprise any
suitable mechanism for drawing liquid from the liquid reservoir and
launching a portion of liquid outwardly from the device. For
example, the liquid projectile launching mechanism can comprise a
simple manual or electric pump mechanism such as are commonly found
in plastic squirt guns; see, e.g., U.S. Pat. Nos. 6,892,902 and
5,373,975, the entire disclosures of which is herein incorporated
by reference. The pump can force liquid directly through and out
the liquid projectile launching mechanism, for example by actuating
a piston operably connected to series of valves which allow the
liquid to be forcibly ejected from the liquid projectile launching
mechanism. Alternatively, the pump can pressurize the liquid
reservoir such that the liquid travels through and out the liquid
projectile launching mechanism when a valve between the liquid
reservoir and liquid projectile launching mechanism is released.
The pump can also be configured to draw liquid into the liquid
reservoir to replenish the liquid supply therein.
[0022] The liquid projectile launching mechanism can also comprise
a bladder or other flexible-walled container. The bladder or other
flexible-walled container can be filled to overcapacity to create
internal pressure, such that liquid can be expelled through an
opening in the liquid projectile launching mechanism. The liquid
projectile launching mechanism comprising a bladder or other
flexible-walled container can also be squeezed to expel the liquid.
Where a liquid projectile launching mechanism comprises a bladder
or other flexible-walled container, the liquid projectile launching
mechanism and the liquid reservoir can be essentially coextensive.
For example, the bladder or other flexible-walled container can be
the liquid reservoir.
[0023] The liquid projectile launching mechanism can also comprise
a mechanism which expels hollow or porous projectiles, which are
filled or saturated with a liquid. Such mechanisms are known in the
art, and can comprise pneumatic systems, spring-loaded systems, or
systems in which the projectile is expelled by the potential energy
of a rubber band or other elastic material, such as are known in
the art. As used herein, a liquid projectile thus includes hollow
or porous projectiles, which are filled or saturated with a liquid.
In such configurations, the liquid reservoir may contain liquid, or
may comprise a magazine or other similar container for holding the
hollow or porous liquid projectiles. It is also contemplated that
the first device can comprise further magazines or similar
containers for holding the hollow shells or porous material before
the liquid has been added. Liquid from a liquid reservoir can then
be apportioned into the hollow shells or porous materials to form
the liquid projectile before the projectile is fired.
[0024] When actuated, the liquid projectile launching mechanism
expels liquid projectiles through at least one discharge tube. The
discharge tube is considered part of the liquid projectile
launching mechanism. The discharge tube can extend away from the
body, and may be constructed so that it can be aimed independently
of the body; i.e., the discharge tube can be positioned to point or
aim in different directions without necessarily changing the
orientation of the device. For example, the discharge tube, or the
entire liquid projectile launching mechanism, can be seated on a
ball bearing, so that the shooting direction can be changed without
moving or changing the orientation of other parts of the device.
Alternatively, the discharge tube is aimed by manipulation of the
entire first device by the user, for example when aiming a
simulated handgun or rifle. The discharge tube can comprise
cylinders of differing diameter (see, e.g., FIG. 1) and can
comprise other components such as a nozzle.
[0025] A discharge tube can be positioned anywhere on the body
which allows liquid projectiles to be projected outwardly from the
device when the liquid projectile launching mechanism is actuated.
As discussed above, the liquid projectile launching mechanism can
be manually or electronically actuated. If electronically actuated,
the liquid projectile launching mechanism can fire multiple liquid
projectiles in succession without further input from the user,
until the electronic signal is stopped or the liquid reservoir is
depleted. Multiple liquid projectiles can also be fired in
succession by manual actuation of the liquid projectile launching
mechanism. Alternatively, manual or electronic actuation of the
liquid projectile launching mechanism can result in the expulsion
of essentially all the liquid in the liquid reservoir at once.
[0026] As used herein, a "liquid projectile" is a portion of
liquid, for example in the form of a drop, projected outwardly from
the device by the liquid projectile shooting mechanism. Once fired
from the first device, the liquid projectile is preferably not
enclosed in any container. A liquid projectile also does not
necessarily have a fixed or constant volume or mass, and the volume
or mass of the liquid projectile may vary from device to device or
between "shots" fired from the device. It is understood that the
liquid projectile can comprise a portion of the liquid in the
liquid reservoir, or can comprise essentially all the liquid in the
liquid reservoir of the device; i.e., all the liquid in the
reservoir can be expelled as one "shot." The velocity of the liquid
projectile when launched from a first device can vary, but is
sufficient to propel the liquid projectile at least some distance
from the first device.
[0027] The liquid which can be used to form the liquid projectiles
of the invention can include any suitable liquid which is
compatible with the device components, and which has a suitably low
viscosity such that it can be discharged from the liquid projectile
launching mechanism. Suitable liquids include water, such as tap
water, spring water, salt water, sugar water or mineral water;
inks, such as "disappearing" and other non-permanent inks and
permanent inks; dyes, for example washable or other non-permanent
dyes and permanent dyes; fluorescent liquids; perfumes; juices;
liquid candies and acidic or basic liquids. Generally, acidic or
basic liquids for use in the invention comprise a weak acid or
base, so as not to damage the device or device components and
surrounding object, or injure a user.
[0028] An exemplary liquid projectile launching mechanism is shown
in FIG. 1. With reference to FIG. 1, the exemplary liquid
projectile launching mechanism 100 comprises a spring 105 engaged
with piston 110 such that the spring 105 forces the piston 110
forward (toward the nozzle 115) when the spring 105 is compressed
by action of the trigger 120 as described below. The piston 110 is
seated in housing 125, which comprises a channel through with the
piston 110 can extend. In use, the liquid projectile launching
mechanism is actuated by depressing trigger 120 such that the
piston is drawn backward (away from nozzle 115) by virtue of the
contact between the trigger 120 and piston surface 130 by flange
135. As the piston 110 is drawn backward, spring 105 is compressed
between piston surface 140 and housing surface 145. When the piston
110 is drawn backwards, water from the fluid reservoir 150 will
fill the interior of the cylinder 155. Upon reaching essentially
the full range of depression, the trigger 120 pivots around a
bearing (marked as hole 160), causing the flange 135 to lose
contact with piston surface 130 and releasing the piston 110. The
piston 110 is then biased forward by the spring 105, and the liquid
in the interior of cylinder 155 will travel through the discharge
tube 165 and finally out through the nozzle 115 with sufficient
velocity to project the liquid away from the nozzle.
[0029] The first device can also comprise electronic components
other than, and optionally connected to, any electronic components
comprising the liquid projectile launching mechanism. Such
electronic components can be activated along with any electronic
components comprising the liquid projectile launching mechanism, or
can be activated separately. For example, the first device can
comprise components for the electronic generation of sound and/or
light. The device can also comprise attachments that are connected
to drive motors activated by the electronics.
[0030] Electronics suitable for use in the first device can include
a power source box, or battery box which can be located suitably in
the body, for containing batteries or another suitable power
source. Suitable wires can be used to couple operable components
such as incandescent lights, LED's, switches and speakers. These
components can be contained in the body, located outside and
supported by the body, or can extend through the body. For example,
one or more portions of the body can be lighted or adapted to glow
by providing a suitable light source such as an LED mounted
adjacent to a chamber with transparent or translucent portion.
[0031] The electronic components can be activated by actuation of
the liquid projectile launching mechanism and/or by the flow of
liquid through the liquid projectile launching mechanism. For
example, a switch can be mounted adjacent to a conduit or a
flexible or soft portion of a conduit, such as conduit carrying
pressurized liquid from the liquid reservoir to or through the
liquid projectile launching mechanism. The deformation or expansion
of the conduit can move one contact element of the switch into
contact with the other element, thus activating the
electronics.
[0032] With regard to fastening, mounting, attaching or connecting
components of the invention to form the first device, unless
specifically described otherwise, such are intended to encompass
suitable conventional fasteners such as screws, nut and bolt
connectors, threaded connectors, snap rings, detent arrangements,
clamps such as screw clamps and the like, rivets, toggles, pins and
the like, as are known in the art. Components can also be connected
by adhesives, glues, welding, ultrasonic welding, and friction
fitting or deformation, if appropriate, and appropriate liquid
and/or airtight seals or sealing devices can be used, as are known
in the art. Electronic portions of the device can use conventional,
commercially available electronic components, connectors and
devices such as suitable wiring, connectors, printed circuit
boards, microchips, speakers, lights, LED's, liquid crystal
displays, pressure sensors, liquid level sensors, audio components,
inputs, outputs and the like.
[0033] The invention also provides a second device, which comprises
a liquid reactive material. As used herein, a "liquid reactive
material" is any material which undergoes a change when contacted
by a liquid. For example, the liquid reactive material can comprise
a substance which changes electrical characteristics (such as
impedance), changes color, or loses or gains opacity when contacted
with a liquid. Suitable liquid reactive materials include a plastic
or cloth that changes color when becoming wet, or a surface which
has been coated with a particulate (e.g., dust, sand, fiberglass,
or the like) on the surface, which particulate changes color or
becomes transparent when wet, revealing an underlying color.
[0034] For example, the second device can comprise a
liquid-responsive switch closing or opening an electric circuit
between a battery and a light or sound source when in contact with
liquid. A suitable liquid-responsive switch, as is known in the
art, comprises a pair of electric terminals impressed with a
certain voltage potential. When in the dry state, the impedance
between the terminals is very high and the current allowed to
circulate is virtually nil. However, when wet, the impedance is
dramatically reduced establishing an electrical path which sets a
simple transistor circuit in the conduction state, closing the
electric circuit between the battery and the light source. Thus,
the second device can be activated to emit sound and/or light when
struck by a liquid projectile from another source. This arrangement
can be used to indicated a "score" or "hit" by a liquid projectile
when simulating combat or team sports play with the devices of the
invention. A liquid-activated switch can also be operably connected
to a liquid projectile launching mechanism, such that the liquid
projectile launching mechanism is temporarily inactivated or
rendered inoperable when the device is struck by liquid.
[0035] Other suitable liquid reactive materials include materials
which react when contacted with an acidic or basic solution, such
as a pH indicator which changes color upon contact with an acid or
a base. A suitable pH indicator is one which changes to a certain
color (e.g., blue) when contacted with an acidic solution, and
changes to another color (e.g., pink or red) when contacted with a
basic solution. Thus, a set, game or kit of the invention can
comprise at least two first devices, and at least two second
devices comprising a pH indicator. One of the first devices can
carry an acidic liquid in its liquid reservoir, and another first
device can carry a basic solution. Hits from the first device
carrying the acidic solution will cause the second devices to turn
a first color, whereas hits from the first device carrying the
basic solution will cause the second devices to turn a second
color. The initial color of the pH indicator on a given second
device can be restored by removing the acidic or basic solution
(such as by washing with water), or by neutralizing with an acidic
or basic solution, as appropriate.
[0036] The second device can be separate from the first device, or
can be carried on or integral to the first device. Numerous
configurations of the first and second device are therefore
possible and contemplated. For example, where the first and second
devices are separate, the first device can comprise a handheld item
such as a simulated weapon (e.g., a handgun, rifle or machine gun),
and the second device can comprise an article to be worn or carried
by a user, such as a shirt, vest, chest plate or other articles
worn on the torso; pants; socks, shin guards, shoes or shoe
coverings, or other articles worn on the feet or legs; belt
(including a harness or Sam Browne belt); badge, necklace,
medallion or the like; helmet, hat or other headcovering; gloves,
rings or other articles worn on the hands; forearm or wrist guards
or other articles worn on the arms; mask, eyeglasses or other
articles worn on the face; a shield or the like; or combinations
thereof. An exemplary second device can comprise a full or partial
suit of armor. For example, mutiple second devices can be provided
with the game, kit or set of the invention, wherein the second
devices comprise different articles of clothing or pieces of armor
(e.g., a chest plate and a back plate, connected by shoulder
straps, or the like).
[0037] The second device can also comprise a free-standing or
independently-moving or randomly-appearing item, such as an
obstacle or target. Exemplary targets can include items that are
thrown or otherwise projected into the air, or "pop-up" targets
representing opponents which appear at random intervals and/or
locations during game play. Such "pop-up" targets can be controlled
by electronics such as are described above, as is known in the
art.
[0038] Where the first and second devices are integral, or the
second device is supported by the first device, the first device
can comprise a handheld or other item such as a simulated weapon
(e.g., a handgun, rifle or machine gun) and the second device can
comprise a target area or other designated area on the first
device. As discussed above, the liquid reactive area can be
operably connected to the liquid projectile launching mechanism of
the first device, such that the liquid projectile launching
mechanism is temporarily disabled when the liquid reactive area is
contacted by liquid.
[0039] Different portions of the second device can comprise at
least two liquid reactive materials which react differently from
each other when wet. For example, one portion of the second device
can comprise a material which turns a first color (e.g., green)
when wet, and a second portion of the same second device can
comprise a material which turns a second color (e.g., blue) when
wet. Thus, a set, game or kit of the invention can comprise at
least two second devices which at least one portion comprising
different liquid reactive materials which react differently when
wet.
[0040] A second device comprising a target can also comprise
materials which react differently from each other when wet. For
example, the outer areas of the target (which are typically
considered lower scoring) can comprise a first liquid reactive
material which turns a first color when wet, and the inner areas of
the target, such as the "bulls-eye" or center (typically considered
higher-scoring) can comprise a second liquid reactive material
which turns a second color when wet.
[0041] The second device can also comprise one or more liquid
reactive materials arranged in a pattern or design, such as for a
game board (e.g., tic tac toe, checkers, darts, etc.), field of
play for a team sport, or the like. Such second devices can
comprise articles of clothing worn by a user, such as are described
above. Hits from liquid projectiles fired from a first device will
cause different portions of the patterned liquid reactive materials
to change color, allowing users to play a game in this manner,
rather than using actual game pieces. For example, users can take
turns firing liquid projectiles at a second device comprising
liquid reactive material arranged in the pattern of a dart board.
The liquid projectile will cause a color or some other change when
it hits, indicating the point of impact. Different point values can
be assigned to different areas of the game board. Alternatively, a
second device comprising liquid reactive material arranged in the
pattern of a tic tac toe board. Each square of the board can
comprise, for example, a liquid reactive material such as a pH
indicator that reacts differently when wetted with an acidic or
basic solution. The liquid reactive material can be arranged in
each square of the tic tac toe board in various patterns, for
example X's and/or O's. Two users can take turns firing liquid
projectiles from a first device at the game board, attempting to
mark three squares in a row. One user can fire liquid projectiles
comprising an acidic solution, while the other user can fire liquid
projectiles comprising a basic solution. Hits from each user will
be registered on the game board as different colors.
[0042] The second device can comprise one or more colors, designs
or indicia, for example for the purpose of decoration or to
indicate different group affiliations. Such colors, designs or
indicia can be those associated with actual armies, sports teams or
sports or military figures. The second device can be any suitable
size which allows a person to use, carry or wear the device, as can
be readily determined by one skilled in the art. In addition to the
liquid reactive material, the second device can be fabricated from
any suitably rigid material using standard techniques, such as
described above for the first device. Likewise, electronics
suitable for use in the second device and the means and techniques
for fastening, mounting, attaching or connecting components of the
invention to form the second device, are as described above for the
first device and are within the skill in the art.
[0043] Sets, games or kits of the invention can be marketed by
packaging the set, game or kit with at least one additional item
for sale, such as candy or gum, stickers, electronic items, and
promotional items such as contests or lotteries and team or league
paraphernalia.
[0044] The first and second devices of the invention can be
utilized to play games in which a user is required to hit an
opponent's second device. Thus, the invention provides a kit or
game comprising at one first device and at least one second device,
and suggested rules of play. For example, the kit or game can
comprise sufficient first and second devices for two teams or
armies of players, with each team or army comprising 1, 2, 3, 4, 5,
10, 20, 50 or more first and second devices.
[0045] Generally, a game of the invention can be played in an open
indoor or outdoor area. The playing surface can be natural or
artificial, and can be, for example, generally planar, uneven or
multi-leveled.
[0046] The area in which a game of the invention is played can be
marked or otherwise carry indicia which simulate, for example,
battle fields or fields of play for one or more team sports. It is
understood that the markings or indicia which simulate a battle
field or field of play can include rear areas, sideline areas or
other areas where individuals not actively participating in the
group activity would be located. One skilled in the art is familiar
with the indicia, relative dimensions and configurations of fields
of play for team sports, and can readily adapt such indicia,
dimensions or configurations for use with the present
invention.
[0047] The kit or game of the invention can also comprise other
items, such as a foldable housing to contain the first and second
devices when not in use, extra liquid or liquid reservoirs,
scorecards or other devices to record game statistics and results,
candy or gum, toys, electronic devices (such as for producing light
and sound effects or play-by-play announcements during game play),
a timing device, stickers or the like for decorating the first or
second devices, and promotional items such as contests or lotteries
and team or league paraphernalia.
[0048] The precise rules of play for a game of the invention depend
on the type of game desired to be played. For example, the game can
comprise rules of play simulating combat. Such rules can be readily
designed and understood by one skilled in the art.
[0049] In one such game, first and second devices sufficient for
two armies can be provided. The individuals playing the game decide
beforehand which army shall have initial possession of which parts
of the battle field, and which army can attack first. For example,
the armies can occupy different sections of the battlefield, or one
army can occupy the entire battle field, and the second army can
attempt to "invade" the occupied territory.
[0050] The game is begun by one or more individuals of a given army
attacking individuals of the other army by firing liquid
projectiles from their first devices at the second devices of the
other army. A player will be "wounded" or "killed" if his or her
second device is struck by the liquid projectile. The "wounded" or
"killed" player is then removed from the battle field or left in
place, and game play continues. "Wounded" players may be
re-introduced to the game after a suitable amount of time has
passed, simulating recovery of the wounded soldier.
[0051] The game progresses with each army attempting to secure the
predetermined objective, and continues until the expiration of a
predetermined time period, the objective is achieved or all the
individuals of one army have been "wounded" or "killed." The
surviving army or army in possession of the predetermined objective
wins the game.
[0052] While the present invention has been described in connection
with the examples discussed above and the various figures, it is to
be understood that other similar examples may be used, or
modifications or additions may be made to the described examples
for performing the same function of the present invention without
deviating therefrom. Therefore, the present invention should not be
limited to any single example, but rather should be construed in
breadth and scope in accordance with the recitation of the appended
claims.
