Description
TECHNICAL FIELD
The present invention relates generally to small simulated weapons, used in the course of military training exercises or recreational war games, that discharge solid or liquid projectiles.
BACKGROUND ART
The military has long engaged in simulated war games as a method of training personnel in the arts of weaponry and combat. More recently, non-military personnel have been engaged in simulated war games as a form of recreation. Whether military or non-military, those engaged in such games use weapons that launch benign colorant projectiles as a means of identifying another whom has been ‘hit’ and is therefore eliminated from the game.
Colorant projectiles are available in the form of paint-balls that may be fired from various spring-loaded or compressed-gas charged devices. Colorant projectiles are also available in liquid form. Presently, it is known to fire paint-balls from devices that resemble pistols, rifles, hand grenades and land mines. It is also known to launch liquid colorant from devices that resemble hand grenades and land mines.
Beyond hand-held pistols and rifles that fire single paint-balls in succession, attempts have been made to develop simulated war game weapons that provide the user with a tactical advantage. For example, it is known to provide reusable compressed-gas charged grenades that can simultaneously launch many paint-balls at an adversary in an effort to simulate the fragmentation of an exploding hand grenade. Also, it is known to provide a reusable compressed-gas charged land mine that simultaneously launches groups of paint-balls in a 360° radius. In addition, it is known to provide a reusable compressed-gas charged land mine that sprays liquid colorant in a 360° radius upon being tripped by a war game participant.
The primary thrust of the known prior art devices is to provide specialized, single function weapons that discharge either solid or liquid colorant projectiles. Because of their specialized nature the existing devices do not offer the user a choice between launching only paint-balls, launching only liquid colorant, or launching both simultaneously. Nor do the known existing devices offer the user a choice between safely holding and firing the device, or concealing the device like a land mine that is aimed to launch colorant projectiles only at the anticipated adversary. Finally, many of the known prior art devices are not concealable nor is it easy to carry many simultaneously.
Thus, there is a need in the art for a reuseable war game device that launches paint-balls or liquid colorant or both simultaneously, can be aimed and fired by the user while hand-held, can be concealed and aimed but remotely triggered, is easy and inexpensive to manufacture, is easy and inexpensive to charge, is easy to dismantle and repair under field conditions, is durable enough to withstand all field conditions, is concealable, is compact, and is easily portable.
SUMMARY OF THE INVENTION
The present invention overcomes the deficiencies of the known prior art devices by providing a reuseable war game device that launches paint-balls or liquid colorant or both simultaneously, can be aimed and fired by the user while hand-held, can be concealed and aimed but remotely triggered, is easy to dismantle and repair under field conditions, is durable enough to withstand all field conditions, and is concealable, compact and easily portable.
Generally speaking the weapon is divided into two main sections, a chambers housing and a launch housing. The launch housing includes a launch barrel connected at both ends by elbows. These elbows are rotatable 360° about a longitudinal axis. Connected to each first elbow is a second elbow. Each second elbow is rotatable 360° about a second longitudinal axis.
Together, the launch barrel and elbows store the projectiles. Projectiles exit the weapon via the launch ports, the open end of the second elbows. The launch ports are aimed by rotating both the first and second elbows, about the respective axes, toward the target. This combination of multiple elbows provides any firing alignment desired by the user.
Covering each launch port is a removable end cap. During storage and transportation each end cap remains in place.
The housings are removably connected. The connection between the housings includes a check valve. The check valve permits flow only from the chambers housing to the launch housing. In this regard, the check valve prohibits liquid projectile from migrating to the chambers housing.
The chamber housing comprises two distinct chambers. The charge chamber contains the power or charge that launches the projectiles. The hammer chamber contains a hammer assembly, namely a hammer, hammer spring, trigger and safety pin.
To safely fire the weapon while hand-held, the user draws back the trigger by pulling the hold portion and then securing the retainer portion about the retainer seat. The action of drawing back the trigger compresses the hammer spring. The user then inserts the safety pin. Next the elbows are rotated so that the launch ports point toward the target(s) and the end caps are removed. The user then releases the retainer from the retainer seat. All that is necessary to fire the weapon and launch the projectiles is to aim and remove the safety pin.
Alternately, to safely fire the weapon while hand-held, the user rotates the elbows toward the target(s), removes the end caps, aims the weapon, draws back the trigger so that the hammer spring is sufficiently compressed and then releases the trigger.
To set the weapon so that it may be triggered by an adversary to fire upon that adversary, such as when the trigger is released by a trip wire, the user plants or otherwise secures the weapon to a surface. The user then draws back the trigger and secures the retainer about the seat. The user inserts the safety pin to secure the hammer in the cocked position, rotates the elbows so that the launch ports aim at the anticipated target(s) and removes the end caps. The user sets a remote trigger such as a trip wire that will cause the retainer to release from the seat. The user then removes the safety pin and all that is necessary to fire the weapon and launch projectiles is to have the trip wire engage.
Whether the weapon is fired while hand-held or set and tripped by another, the projectiles exit the launch port through the same sequence of events. When the hammer is released from the cocked position the hammer spring uncoils, throwing the hammer toward the container. The pointed ram hits and ruptures the thin seal at the top of the container causing the compressed-gas to violently escape in the usual manner. The escaping gas pushes open the check valve and passes into the launch barrel. The forces exerted by the gas push the projectiles at rapid speed out the launch ports and toward their intended target(s).

DETAILED DESCRIPTION
Referring now to the drawings, wherein like numerals refer to like parts throughout the several views,
FIG. 1
shows a top view of a war game weapon
10
embodying the present invention. In
FIG. 1
the weapon
10
is illustrated in the folded configuration as it would be for safe storage or carrying.
FIG. 2
shows a side view of the weapon
10
also in the folded configuration.
Generally speaking the weapon
10
is divided into two main sections, the chamber housing
12
and the launch housing
14
. As explained below in detail, the chamber housing
12
contains the trigger, firing assembly and charge while the launch housing
14
contains the colorant projectiles. War game weapons launch benign colorant projectiles as a means of identifying another whom has been ‘hit’ and is therefore eliminated from the game.
As best illustrated in
FIG. 3
, the launch housing
14
comprises a number of parts. In the illustrated embodiment, the launch barrel
20
is a generally straight portion which is connected at both ends to two separate muzzle assemblies. Embodiments with fewer or more muzzle assemblies are contemplated. Here, a muzzle assembly is comprised of two 45° elbows
22
,
23
. The first elbows
22
are joined to the launch barrel
20
such that the first elbows
22
are rotatable 360° about the longitudinal axis A. Connected to each first elbow
22
at the end opposite the connection to the launch barrel
20
, is a second elbow
23
. Each second elbow
23
is joined to a respective first elbow
22
such that the second elbows
23
are, in one embodiment, rotatable 360° about the longitudinal axis B. However, embodiments allowing less then 360° rotation are contemplated.
The launch barrel/elbow and elbow/elbow connections are formed, as known by those skilled in the art, to provide an easy disconnect while maintaining a pressure resistant liquid tight seal. In the illustrated embodiment, friction-fit bell and spigot joint ends form these connections. The combination of multiple elbows
22
,
23
provides any firing alignment desired by the user.
Together, the launch barrel
20
and elbows
22
,
23
form a combination hold/launch barrel that stores the projectiles
24
. As noted above, both military training exercises and recreational war games use non-lethal colorants as projectiles to mark ‘hits’. Paint-balls and liquid are two popular forms of colorant projectiles. For the purposes of this description, all forms of non-lethal colorant projectiles are referred to as projectiles
24
. Nevertheless, while this description is directed to non-lethal projectiles, it will be understood that the term projectile extends to include injury-inflicting lethal projectiles.
Each elbow
23
is configured, at the end opposite the connection to the elbow
22
, to securely engage an end cap
26
. In the illustrated embodiment, the elbow
23
and end cap
26
are both threaded to mate and provide a pressure resistant liquid tight seal. During storage and transportation each end cap
26
is connected to a respective elbow
23
. In this manner the projectiles
24
are contained, even in the event a cocked weapon is inadvertently discharged. As explained below in greater detail, projectiles
24
exit the weapon
10
via launch ports
28
. The launch ports
28
are aimed, as explained above, by rotating elbows
22
,
23
about the respective axes A, B.
The launch housing
14
and chambers housing
12
are joined together using methods well known to those skilled in the art. For example, in the illustrated embodiment the housings
12
,
14
are mated with threaded connections. Because the weapon
10
is easily disassembled, maintenance and replacement is accomplished quickly and efficiently.
In this embodiment, the launch housing
14
and chamber housing
12
are connected via an outside threaded nipple
29
attached to the launch housing
14
, that mates with an inside threaded bushing
30
attached to the chamber housing
12
. Like the connections described above, this connection is also configured to provide a pressure resistant liquid tight seal.
The connection between the launch housing
14
and chamber housing
12
includes a check valve
31
. As explained in detail below, the check valve
31
preferably only permits flow F from the chamber housing
12
to the launch housing
14
. In this regard, the check valve
31
prohibits liquid projectile
24
from migrating to the chamber housing
12
.
The chamber housing
12
comprises two distinct chambers. The charge chamber
32
contains the power or charge that launches the projectiles
24
. In this embodiment, the charge is compressed-gas in the well known CO
2
container
34
. The typical CO
2
container is cylindrical, includes a rounded bottom and is of uniform diameter except at the top where the container tapers to a small neck and top. The container
34
is inserted into the chamber
32
. To secure the container
34
the chamber
32
includes support shoulders
36
. The container
34
is nested against the shoulders
36
and retained within the chamber
32
by the end cap
38
. In this embodiment, the housing
12
is threaded to mate with the end cap
38
which is likewise threaded.
The hammer chamber
40
contains a hammer assembly comprising a hammer
42
and the associated spring-loaded trigger mechanism. The hammer
42
includes a safety pin receiver
44
and ram
46
. In this embodiment, the hammer
42
is shaped like an hour-glass with a pointed end. Here the area of narrowest dimension is the safety pin receiver
44
and the pointed end is the ram
46
. In
FIG. 3
the hammer
42
is shown in the uncocked position. That is, the hammer
44
is loose and not poised to rupture the container
34
causing the compressed-gas contents to discharge.
In the cocked position (not illustrated), the hammer
42
is drawn back and held within the hammer chamber
40
at the end opposite the location illustrated in FIG.
3
. In the cocked position the safety pin
48
is engaged by inserting it into a first safety pin orifice
50
so that it extends across the safety pin receiver
44
and through a second safety pin orifice
50
. When engaged in this manner, the safety pin will securely hold the hammer
42
in place.
In the cocked position, the hammer spring
52
is compressed between the hammer
42
and the hammer chamber end cap
54
. Like the charge chamber end cap
38
, the end cap
54
is also threaded to mate with the threaded end of chamber housing
12
. The hammer chamber end cap
54
includes a trigger orifice
56
which permits passage of the trigger
58
.
The orifices
50
,
56
as illustrated are configured to function as safety valves that permit compressed-gas to escape in the event of an unintentional discharge. In an alternative embodiment, the orifices
50
,
56
may be sealed to prevent the entry of debris, moisture and ambient air. Such an alternative embodiment may include a separate safety valve.
In this embodiment, the trigger
58
is a flexible member surrounded partially by the hammer spring
52
and attached to the hammer
42
. At a distal end the trigger
58
includes a retainer portion
60
and a hold portion
62
. When cocked, the trigger
58
is held in the cocked position by securing the retainer portion
60
around the retainer seat
64
as best shown in
FIGS. 1 and 2
.
Operation
Generally, as best shown in
FIGS. 1 and 2
, the weapon
10
may be stored or transported with the charge container
34
and projectiles
24
in place by leaving the hammer
42
in the uncocked position. In other words, the weapon
10
may be stored or carried with the safety pin
48
in place and the retainer
60
over the seat
64
but without the hammer spring
52
being compressed. Generally, to launch the projectiles
24
, the user may handhold and fire the weapon
10
or conceal and set the weapon
10
to be tripped by others.
As best described with reference to
FIG. 3
, to fire the weapon
10
while hand-held, the user grasps the chambers housing
12
generally around that section which houses the container
34
. The user then draws back the trigger
58
by pulling the hold portion
62
and securing the retainer portion
60
about the retainer seat
64
. The action of drawing back the trigger
58
retracts the hammer
42
and compresses the hammer spring
52
. The hammer spring
52
is now fully compressed and the hammer
42
is in the cocked-position. The user then inserts the safety pin
48
, as described above, to secure the hammer
42
in the cocked position. Next the elbows
22
,
23
are rotated so that the launch ports
28
point toward the target(s), and the end caps
26
removed. The user then releases the retainer
60
from the retainer seat
64
. At this time, all that is necessary to fire the weapon
10
and launch the projectiles
24
is to aim and remove the safety pin
48
from the engaged position.
Alternately, to fire the weapon
10
and launch projectiles
24
while the weapon is hand-held, the user grasps the chambers housing
12
, rotates the elbows
22
,
23
toward the target(s), removes the end caps
26
, aims the weapon
10
, draws back the trigger
58
so that the hammer spring
52
is sufficiently compressed and then releases the trigger
58
.
To set the weapon
10
so that it may be triggered by an adversary to fire upon that adversary, such as when the trigger
58
is released by an engaged trip wire (not shown), the user plants or otherwise secures the weapon
10
to a surface (not shown). Suitable horizontal surfaces, by way of illustration and not limitation, include earthen ground, fallen trees, finished and unfinished exterior paths, and the interior floors and ceilings of a structure. Suitable vertical surfaces include trees, the exterior of structures, and the interior walls of structures, just to name a few examples.
To set the planted weapon
10
, the user secures it to the surface by fastening around the chambers housing
12
, threaded bushing
30
, or launch barrel
20
. In an alternative embodiment, mounts may be provided for receiving fasteners that permit connecting to a surface. The user draws back the trigger
58
by pulling the hold portion
62
and securing the retainer
60
about the seat
64
. The hammer spring
52
is now fully compressed and the hammer
42
is in the cocked position. The user then inserts the safety pin
48
, as described above, to secure the hammer
42
in the cocked position. Next the elbows
22
,
23
are rotated so that the launch ports
28
aim at the anticipated target(s), and the end caps
26
removed.
The user sets a remote trigger such as a trip wire (not shown) which, when engaged, will cause the retainer
60
to release from the seat
64
. The user then removes the safety pin
48
from the engaged position. All that is necessary to fire the weapon
10
and launch projectiles
24
is to have the trip wire engage.
Alternatively, the user does not secure the retainer
60
about the seat
64
but inserts the safety pin
48
which is then connected to a trip wire. All that is necessary to fire the weapon
10
and launch the projectiles
24
is to have the trip wire
66
engage.
The illustrated embodiment includes a trip wire. However, it is considered that other remote trigger mechanism may be incorporated such as, by way of illustration and not limitation, pressure pads, shock indicators, sound detectors, and light beams connected to a means for releasing the retainer
60
, releasing the safety pin
48
, or retracting the retainer seat
64
.
Whether the weapon
10
is fired while hand-held or set and tripped by another, the projectiles
24
exit the launch port
28
through the same sequence of events. When the hammer
42
is released from the cocked position the hammer spring
52
uncoils, throwing the hammer
42
toward the container
34
. The pointed ram
46
hits and ruptures the thin seal at the top of the container
34
causing the compressed-gas to violently escape in the usual manner. The escaping gas rushes past the hammer
42
, pushes open the check valve
31
, and passes into the launch barrel
20
as indicated by the flow arrows F. The forces exerted by the gas push the projectiles
24
at rapid speed out the launch ports
28
and toward their intended target(s).
In the case of discrete projectiles
24
such as paint-balls, the projectiles will be launched successively without interruption. That is, as a unit, like shrapnel. In the case of liquid, the projectile
24
will be launched en masse. It is considered that where only liquid projectile is launched, a shield (not shown) may cover the launch ports
28
to create a spray pattern or otherwise control the speed and direction of the liquid projectile
24
.
Generally, the materials selected to construct the weapon
10
should be selected to endure harsh battlefield conditions. Heavy schedule PVC and non-corrosive metals are likely design choices.
While the present invention in its various aspects has been described in detail with regard to a preferred embodiment, alternative embodiments are considered. It should be understood that variations, modifications and enhancements can be made to the disclosed apparatus and procedures without departing from the scope of the present invention as defined in the appended claims.
