Abstract
A war games land mine includes a fluid supply mechanism, a housing and a sealing device. The fluid supply mechanism is configured for containing and selectively releasing therefrom a pressurized fluid. The housing has an interior surface, a first orifice and a second orifice, the first orifice of the housing being fluidly coupled with the fluid supply mechanism. The sealing device is movably mounted within the housing, the sealing device having a first side and a second side. The first side and the interior surface of the housing define a first chamber therebetween, the first chamber being fluidly coupled with the first orifice. The second side and the interior surface defining a second chamber therebetween, the second chamber being fluidly coupled with the second orifice and configured for being substantially filled with a marking agent. The sealing device is configured for being moved within the housing upon release of the pressurized fluid from the fluid supply mechanism to thereby eject the marking agent through the second orifice.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a war games land mine, and, more particularly, to a war games land mine which uses the release of a gas under pressure to cause the discharge of a marking agent.
2. Description of the Related Art
War games land mines are currently available for use in simulated war games. Such war games land mines typically incorporate some form of a marking agent such as paint or water. Several of these war games land mines generate the force needed to disperse the marking agent by piercing of a CO
2
cartridge, with the CO
2
directly impacting upon the marking agent. Such a system presents a problem in that the marking agent is not fluidly separated from the actuator/piercing mechanism, allowing the marking agent to potentially contaminate this mechanism and other areas of the land mine.
SUMMARY OF THE INVENTION
The present invention relates to a war games land mine which uses a piston within a cylinder arrangement to discharge the marking agent through a discharge nozzle and to thereby fluidly separate the marking agent from the actuator/piercing mechanism and prevent contamination of other portions of the war games land mine.
The invention comprises, in one form thereof, a war games land mine including a fluid supply mechanism, a housing and a sealing device. The fluid supply mechanism is configured for containing and selectively releasing therefrom a pressurized fluid. The housing has an interior surface, a first orifice and a second orifice, the first orifice of the housing being fluidly coupled with the fluid supply mechanism. The sealing device is movably mounted within the housing, the sealing device having a first side and a second side. The first side and the interior surface of the housing define a first chamber therebetween, the first chamber being fluidly coupled with the first orifice. The second side and the interior surface defining a second chamber therebetween, the second chamber being fluidly coupled with the second orifice and configured for being substantially filled with a marking agent. The sealing device is configured for being moved within the housing upon release of the pressurized fluid from the fluid supply mechanism to thereby eject the marking agent through the second orifice.
An advantage of the present invention is that the marking agent is maintained fluidly separate from the gas-source module, including the trigger assembly, preventing the contamination thereof with the marking agent.
A further advantage of the present invention is that the impact of pressurized fluid upon the piston promotes steady and even dispersal of the marking agent through the nozzle.
Another advantage of the present invention is that both refillable and disposable marking agent containment systems are available for use therewith.
An additional advantage of the present invention is that the gas-source module can be adapted to use various sources of pressurized gas, including gas cartridges, large bottles of gas and air compression systems, or other pressurized fluid.
A yet another advantage is that any of a variety of marking agent release activators may be used, including, but not necessarily limited to, a trip wire, a motion sensor, a proximity sensor, a radio frequency receiver/transceiver, a timer and an electronic controller.
A further advantage is that the device can be provided with a manual reset device for each of the piercer driver/hammer and the piston.
A yet further advantage is that any of a variety of marking agents may be used including, but not necessarily limited to, paint and water.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, and more particularly to
FIGS. 1-3
, there is shown a war games land mine
20
which generally includes a gas-release module
22
and a marker-source module
24
. Gas-release module
22
further includes a gas source
28
and a trigger assembly
30
. Marker-source module
24
further includes a marker-source module housing
32
, a delivery nozzle
34
and a piston
36
.
Gas source
28
is a source of a gas under pressure. Gas source
28
is preferably a gas cartridge
38
filled with carbon dioxide or air. Gas cartridge
38
has a neck
40
with a sealed opening
42
at the end thereof Alternatively, gas source
28
may be a compressed gas source (not shown) such as a larger bottle or compressed air system using a valve to selectively release the gas therein. The primary function of gas source
28
is to provide a fluid under pressure that can be selectively released and eventually impinge upon piston
36
. Consequently, it is contemplated that any pressurized fluid, such as a pressurized liquid, could be provided to fulfill this function.
Gas-release module housing
26
includes housing elements for both gas source
28
and trigger assembly
30
. Specifically, gas-release module housing
26
includes gas cartridge receiver
44
into which gas cartridge
38
is inserted. Neck
40
of gas cartridge
38
is positioned within cartridge seat
46
. Sealed opening
42
of neck
40
abuts against seal
48
, seal
48
being composed of polytetraflouroethylene (PTFE). Cartridge seat
46
is sealingly held in contact with gas cartridge receiver
44
by an O-ring
50
. O-rings
50
are used throughout war games land mine
20
for purposes of sealingly retaining fluid materials within war games land mine
20
and/or holding contacting parts together, a portion of such O-rings
50
being labeled. Gas cartridge
38
is releasably held within gas cartridge receiver
44
by a cartridge cap
52
. Preferably, cartridge cap
52
may be screwed into gas cartridge receiver
44
.
Gas-release module housing
26
further includes a main trigger housing
54
, a manifold
56
and a manifold lid
58
for collectively containing trigger assembly
30
. Main trigger housing
54
, manifold
56
and manifold lid
58
together define a first gas channel
60
for channeling gas from gas source
28
toward marker-source module
24
. Manifold lid
58
is attached to manifold
56
by manifold mounting bolts
62
(one of which is labeled). Main trigger housing
54
is sealingly mounted between gas cartridge receiver
44
and manifold
56
.
Trigger assembly
30
includes, in the embodiment shown in
FIGS. 1-3
, a piercer
62
and a hammer
64
, which acts as a piercer driver. Piercer
62
is mounted in piercer housing
66
, piercer housing
66
being positioned within main trigger housing
54
. Piercer
62
has a sharp end
68
and a blunt end
70
. Sharp end
68
is located adjacent sealed opening
42
of neck
40
and is configured for piercing therethrough, such piercing thereby initiating a gas flow
72
(shown schematically, in
FIG. 3
) from gas cartridge
38
. Sharp end
68
of piercer
62
is biased away from sealed opening
42
by a spring
74
.
Hammer
64
is slidably positioned within hammer sleeve
76
, manifold
56
and manifold lid
58
. Specifically, hammer head
78
is slidable along hammer sleeve
76
, and hammer stem
80
is slidable within manifold
56
, through stem hole
81
, and manifold lid
58
. Hammer spring
82
, which is positioned between hammer head
78
and manifold
56
, provides the momentum necessary, when released, to drive hammer head
78
at blunt end
70
of piercer
62
and to thereby drive sharp end
68
thereof into sealed opening
42
of gas cartridge neck
40
, allowing gas flow
72
to emanate from gas cartridge
38
.
Hammer stem
80
has a notch
84
therein for receiving trigger catch
86
. Hammer stem
80
is also provided with a pull ring
88
for pulling hammer
64
into a reset position in which trigger catch
86
engages with notch
84
. Hammer stem
80
is further provided with a safety clip hole
90
for receiving safety clip
92
therein (shown assembled in
FIG. 1
) to prevent unwanted firing of hammer
64
against piercer
62
. Safety clip
92
is preferably tethered (not shown) to war games land mine
20
to prevent the loss of safety clip
92
when not attached to hammer stem
80
.
Trigger catch
86
and the mechanisms related to its movement are best seen in
FIGS. 4 and 5
, which are sectional views of
FIGS. 2 and 3
, respectively. Trigger catch
86
, as shown in
FIG. 4
, is held against notch
84
of hammer stem
80
by the coaction of tension spring
94
and solenoid trigger
96
. Steel pins
98
are used to aid in the positioning of each of trigger catch
86
, tension spring
94
and solenoid trigger
96
. Solenoid trigger
96
is coupled with a solenoid
100
which acts as a biasing device therefor. Solenoid
100
is positioned within an electronics control module (ECM)
102
, ECM
102
being mounted below gas-release module
22
and marker-source module
24
.
Trigger catch
86
may be released from notch
84
, thereby allowing hammer
64
to be activated, either mechanically by use of a trip wire
104
(
FIGS. 1 and 4
) or by a reverse operation of solenoid
100
, as indicated schematically by arrow
106
in
FIG. 5. A
reverse operation of solenoid
100
may be initiated by a motion sensor, a proximity sensor, a radio frequency transmitter/receiver and/or a timer incorporated in and/or associated circuit board
108
(
FIG. 6
) of ECM
102
. Solenoid
100
and circuit board
108
are preferably powered by a pair of nine volt batteries
110
. Solenoid
100
, circuit board
108
and nine volt batteries
110
are each shown in phantom in FIG.
6
.
Marker-source module housing
26
is defined by primary cylinder
112
, manifold
56
and manifold lid
58
, the three of which together define a second gas channel
114
. First gas channel
60
and second gas channel
114
come in direct fluid communication with one another in a region between manifold
56
and manifold lid
58
, thereby allowing gas flow
72
to proceed from gas-release module
22
into marker-source module
24
. First end
116
, having a first orifice
117
, of primary cylinder
112
is preferably threadingly connected to manifold
56
. Primary cylinder
112
essentially functions as a housing and a container so it is contemplated that other appropriate housing configurations could be employed.
Delivery nozzle
34
includes a cap
118
and a spray release mechanism
122
. Cap
118
is connectable to second end
120
, having a second orifice
121
, of primary cylinder
112
, preferably by screw threading, as shown schematically in FIG.
6
. Spray release mechanism
122
includes a spray deflector
124
and a deflector biasing spring
126
. Spray deflector
124
may be designed to create one or more streams or sprays at angles ranging from 1 to 360°. Deflector biasing spring
126
tends to bias spray deflector
124
into a closed position within delivery nozzle
34
. The presence of a force F is needed to overcome that bias and to cause spray release mechanism
122
to activate and thereby permit release of a marking agent
128
. Alternatively, marking agent
128
could be directly ejected out of second orifice
121
of second end
120
, second orifice
121
having a diameter equal to or less than that of second end
120
.
Marking agent
128
is composed of at least one of a marking fluid and a marking slurry. Marking agent
128
is preferably water or a washable paint. Piston
36
has a first piston side
130
and a second piston side
132
. Marking agent
128
is contained within primary cylinder
112
in a volume or marker chamber
131
defined at one end by cap
118
and at another end by second piston side
132
of piston
36
.
First piston side
130
is in fluid communication with second gas channel
114
and is thereby in the pathway of gas flow
72
upon release of gas from gas cartridge
38
. Primary cylinder
112
and first piston side
130
together form a gas chamber
133
for receiving gas flow
72
. Impingement of gas flow
72
upon first piston side
130
causes piston
36
to move towards delivery nozzle
34
, ultimately creating a sufficient force F upon spray deflector
124
to overcome deflector biasing spring
126
, resulting in the outward release of marking agent
128
through spray release mechanism
122
. The provision of O-rings
50
within piston
36
helps to ensure that no marking agent
128
leaks back into second gas channel
114
. Conversely, O-rings
50
in piston
36
also help to minimize, if not prevent, unwanted leakage of gas flow
72
around piston
36
, thereby helping to maximize the amount of force with which gas flow
72
is able to impact first piston side
130
.
Marker-source module
24
may be further provided with a reset rod
134
for resetting piston
36
from its “as fired” position
136
, as shown in
FIG. 3
, to its “loaded” position
138
, as shown in FIG.
2
. Reset rod
134
is preferably provided on its exterior end
140
with a knob
142
to aid in pulling piston
36
to its “loaded” or reset position
138
. Interior end
144
of reset rod
134
has a clip
146
mounted thereto to allow reset rod
134
to engage with second piston side
132
during reset of piston
36
. Upon resetting, cap
118
of delivery nozzle
34
can be removed from primary cylinder
112
to allow refilling thereof with marking agent
128
and then reaffixed to primary cylinder
112
.
An alternative marker-source module housing
150
is shown in
FIGS. 7-10
. Marker-source module
150
includes a disposable marker cartridge
152
, a primary cylinder
154
, an adapter
156
, a retainer bolt
158
and a delivery nozzle
160
. Primary cylinder
154
and delivery nozzle
160
are similar in structure and function to primary cylinder
112
and delivery nozzle
34
, respectively, of the first embodiment and thus are not discussed in great detail with regard to this embodiment.
Disposable marker cartridge
152
, as best seen in
FIG. 8
, includes a disposable cylinder
162
, a disposable piston
164
and a pull-tab seal
166
, with a marking agent
168
therein. Disposable cylinder
162
is sized so as to fit within and against primary cylinder
154
. Disposable cylinder
162
is provided with an open end
170
into which disposable piston
164
is sealingly and slidably received. Delivery end
172
of disposable cylinder
162
has a delivery hole
174
therein, as best shown in
FIG. 9
, through which marking agent
168
may reach delivery nozzle
160
. Delivery hole
174
is covered by pull-tab seal
166
during storage and delivery, with pull-tab seal
166
being removed prior to insertion of disposable marker cartridge
152
into marker-source module
150
.
Disposable piston
164
has a hollow cup shape. Disposable piston
164
is provided with at least one rounded ridge
176
which permits a relatively small portion of the surface area of disposable piston
164
to actually be in contact with disposable cylinder
162
while still achieving a sufficient seal therebetween.
Adaptor
156
permits various size disposable cylinders
162
to be sealingly connected with manifold
56
. Adaptor taper
178
accommodates such size variation. Adapter
156
is provided with a gas-flow hole
180
to permit gas to flow from manifold
56
into disposable cylinder
162
and toward disposable piston
164
. Adaptor
156
is further provided with a tap seat
182
for receiving retainer bolt
158
via which adaptor
156
can be releasably fixed to and in proper alignment with manifold
56
.
ECM
102
may allow for a variety of electronic features to be added on or included therein. An electronic display for displaying information or a buzzer for audibilizing information may be provided. A timer function would permit the automatic firing of the unit. A radio frequency transmitter may generate more than one code for firing of more than one land mine. A transceiver may also be adopted for sending and receiving RF signals. The transceiver could be further used to allow communication between players on the field as well as being used as a firing device. A servo-motor can substitute for the solenoid for activating the trigger. The servo-motor, having positional accuracy, may also activate another device other than the trigger.
The electronic housing (not labelled) of ECM
102
would preferably be molded of plastic. The molded housing may then incorporate a power switch for more economical manufacture. External contacts may be provided for another device or for a device-to-device physical connection.
In another alternate embodiment, war games land mine
190
(
FIG. 11
) is shown in an as-fired condition. War games land mine
190
has a gas-release module
192
and a marker-source module
194
, the latter including a nozzle
195
. Gas-release module
192
is equipped and functions similar to gas-release module
22
and is not described in further detail with respect to this embodiment. Further, marker-source module
194
is equipped and functions similar to marker-source module
24
except for those details expressly described herewith. Specifically, piston
196
has piston hole
198
with an O-ring
199
positioned therein. Reset rod
200
extends through piston hole
198
during a firing and reset sequence. Reset rod
200
has an exterior end
202
and an interior end
204
, interior end
204
having an associated retaining clip
205
(retaining clip
205
being configured similar to clip
146
). Reset rod
200
has a primary diameter
206
beginning at exterior end
202
and extending to, but not including, interior end
204
. At least a portion of interior end
204
instead has a secondary diameter
208
which is slightly less than primary diameter
206
. Primary diameter
206
is chosen so as to result in an essentially gas-tight seal with piston hole
198
and O-ring
199
yet to allow relatively easy movement of piston
196
upon reset rod
200
. However, at interior end
204
, a gas-tight seal between piston hole
198
, O-ring
199
and reset rod
200
does not exist due to the gap therebetween resulting from secondary diameter
208
being less than primary diameter
206
. Consequently, at the end of a firing cycle, i.e. when piston
196
reaches interior end
204
of reset rod
200
, gas used for the firing sequence can escape beyond piston
199
and outward through nozzle
195
.
In yet a further embodiment, war games land mine
210
(
FIG. 12
) is shown from a cut-away end view along a plane between a manifold (not shown) and manifold lid
212
. War games land mine
210
includes both a hammer stem
214
and a reset or piston rod
216
, with hammer stem
214
also having a corresponding hammer notch
218
therein. Hammer stem
214
and hammer notch
218
are structured and function similar to hammer stem
80
and notch
84
and, thus, are not discussed in further detail here. However, reset rod
216
is provided with a reset notch
220
and has a reset rod stabilizer
222
associated therewith. Reset rod stabilizer
222
is pivotally positioned upon pin
224
(upon which pin
224
a solenoid trigger (not shown in this embodiment) is also positioned and pivots about). Reset rod stabilizer
222
has a stabilizer set position
226
and a stabilizer release position
228
(shown in phantom in FIG.
12
). Reset rod stabilizer
222
has a stabilizer spring
230
associated therewith, and when in stabilizer set position
226
, reset rod stabilizer
222
is biased into reset notch
220
by stabilizer spring
230
. Reset rod stabilizer
222
is kept in stabilizer set position
226
during the firing sequence to help restrict the movement of and thereby stabilize the positioning of reset rod
216
through the turbulence created by the firing sequence.
War games land mine
20
is operated in the following manner. Trigger assembly
30
is activated in order to release the gas from gas source
28
and into first gas channel
60
. The gas thereby flows from first gas channel
60
into second gas channel
114
. Upon flowing into second gas channel
114
, the gas impacts upon first piston side
130
of piston
36
. Piston
36
is moved as a result of the impaction of the gas upon first piston side
130
, thereby actuating second piston side
132
against marking agent
128
. Second piston side
132
impacts against marking agent
128
with a sufficient force to cause at least a substantial portion of marking agent
128
to thereby be expelled through delivery nozzle
34
, causing a spray or stream of marking agent
128
to emanate therefrom.
Various other alternative features (not shown) are possible. Nozzle
34
may be a single-hole nozzle having a servo-controlled axial latitude and longitude, operable from an RF transmitter. Additionally, the orifice size and/or flow of fluid from nozzle
34
may be regulated manually or by servo. The flow is restricted by varying how much of the flow passage is blocked by a movable gate. With respect to trigger assembly
30
, solenoid
100
itself may be used to provide the energy for piercing gas cartridge
38
by axially aligning the two, using a solenoid of the push-type variety. Furthermore, gas cartridge receiver
44
, cartridge seat
46
and main trigger housing
54
could be combined into one unitary part as so could piercer housing
66
and hammer sleeve
76
. Separate parts were used in the first embodiment due to ease of manufacture. Reset rod
134
, although easing piston reset, is not required therefor. Reset rod
134
is also not necessary when using disposable marker cartridge
152
.
Instead of gas cartridge
38
as the gas source, a compressed gas system, such as a larger bottle or a compressed air system, incorporating a valve release, could be used. In such an instance, a valve release mechanism would be used as part of the trigger assembly instead of a piercer assembly. A yet further alternative would be to replace gas source
28
with another pressurized fluid source.
In general, many components of this product would ideally be made of plastic, aluminum or other material that is inexpensive; readily formed and/or machined; and both mechanically and chemically durable. Additionally, such components may be made by any of a variety of appropriate manufacturing methods.
While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles.
