Paintball Marker with Mode Selector
Abstract
A paintball marker that includes both a mechanical firing mode
and an electronically-assisted firing mode. In the mechanical
firing mode, the marker launches projectiles without the aid of
electronics and therefore does not require an energy source, such
as batteries. In the electronically-assisted firing mode, an
electronic circuit initiates launching of projectiles. A mode
selector is provided that allows a user to select between the
mechanical firing mode and the electronically-assisted firing
mode.

TECHNICAL FIELD
[0002] The present invention relates generally to paintball
markers, and like devices for firing frangible projectiles. In
particular, this invention relates to a paintball marker that can
selectively fire in either a mechanical firing mode or an
electronically-assisted firing mode.
BACKGROUND
[0003] Paintball is a popular sport in which opposing sides attempt
to seek out and "shoot" one another with paintballs. Players use
paintball markers (also known as paintball guns) to propel the
paintballs with compressed gas or combustible fuel. The paintballs
are designed to break upon impact and leave a visible mark.
[0004] Since paintball games often simulate combat, paintball
markers that resemble military equipment are desirable to increase
the realism of the experience. For example, paintball markers have
been modified to resemble assault rifles, sniper rifles, etc. In
some cases, however, such modifications can be difficult to install
and remove. Moreover, the modifications may detract from the
marker's functionality and reliability.
SUMMARY
[0005] According to one aspect, the invention provides a paintball
marker with a receiver and a barrel extending from the receiver.
The marker includes a valve arrangement configured to selectively
vent gas to propel a projectile out of the barrel. A mode selector
may be provided to switch between a mechanical firing mode and an
electronically-assisted firing mode. The marker includes a trigger
that is movable between a neutral position and a firing position. A
mechanical launch assembly is provided that may actuate launching
of a projectile responsive to the trigger moving to the firing
position without electronic assistance. The marker may also include
an electronic circuit configured to actuate launching of a
projectile responsive to the trigger moving to the firing position.
When the mode selector is in the mechanical firing mode, the
mechanical launch assembly actuates launching of a projectile. When
the mode selector is in the electronically-assisted firing mode,
the electronic circuit actuates launching of a projectile.
[0006] In one embodiment, a mechanical linkage is movable between a
first position away from the valve arrangement and a second
position that actuates the valve arrangement. The mechanical
linkage actuates the valve arrangement responsive to the trigger
moving to the firing position when the mode selector is in the
mechanical firing mode. The electronic circuit initiates actuation
of the valve arrangement responsive to the trigger moving to the
firing position when the mode selector is in the
electronically-assisted firing mode. For example, the electronic
circuit may include a linear actuator configured to move to actuate
the valve arrangement by energizing the linear actuator responsive
to the trigger moving to the firing position when the mode selector
is in the electronically-assisted firing mode.
[0007] Embodiments are contemplated in which the mode selector
includes a notch dimensioned to receive a tip extending from the
trigger. The notch is aligned with the tip when the mode selector
is in the mechanical firing mode such that the tip is in registry
with the notch when the trigger moves to the firing position. In a
safety mode, however, the notch is not aligned with the tip to
block the trigger from moving to the firing position. In another
embodiment, a magnet may be associated with the mode selector and a
magnetic sensor could be provided that is configured to detect the
magnet when the mode selector is in the electronically-assisted
firing mode, but not when the mode selector is in the mechanical
firing mode.
[0008] Additional features and advantages of the invention will
become apparent to those skilled in the art upon consideration of
the following detailed description of the illustrated embodiment
exemplifying the best mode of carrying out the invention as
presently perceived. It is intended that all such additional
features and advantages be included within this description and be
within the scope of the invention.

DETAILED DESCRIPTION OF THE DRAWINGS
[0058] FIGS. 1-9 illustrate an example paintball marker 100
constructed according to an embodiment of the present invention.
The invention could be implemented in a manual, semi-automatic, or
automatic marker, even though a semi-automatic marker is shown for
purposes of illustration. It should be appreciated that the marker
100 could use a variety of propellants to propel paintballs (or
other projectiles) from the marker 100. The term "propellant" is
broadly intended to encompass both compressed gas, such as carbon
dioxide and nitrogen, as well as combustible fuel, such as propane,
butane, and methylacetylene-propadiene ("MAPP").
[0059] In the example shown, the marker 100 includes a barrel 102
through which projectiles may be propelled. As shown, the barrel
102 is coupled with a receiver 104, which defines an interior
cavity dimensioned to house internal components of the marker 100.
As used herein, the term "coupled" is broadly intended to encompass
both direct and indirect connections. Typically, the barrel 102
includes external threads that may be received by internal threads
in the receiver 104. By way of other examples, the barrel 102 may
attach to the receiver 104 with an interference fit, frictional
fit, or unitary formation. The receiver 104 may be formed from a
variety of materials, such as aluminum, stainless steel, magnesium,
or composites. In embodiments in which the receiver 104 is made of
magnesium, it has been found that the production molds last
substantially longer than that of aluminum. In some embodiments,
the receiver 104 may have a clamshell-type body.
[0060] In the embodiment shown, the marker 100 includes a forestock
106. As best seen in FIGS. 10 and 10A, the forestock 106 may
include a bore 107 dimensioned to receive the barrel 102.
Preferably, the forestock 106 may be detachably coupled to the
receiver 104. In the example shown, a first pin 108 and a second
pin 110 extend through holes 111 in the forestock 106 and holes 113
in the receiver 104 (FIG. 2), thereby coupling the forestock 106 to
the receiver 104. In this example, the forestock 106 may be
detached from the receiver 104 by removing the pins 108 and 110 and
sliding the forestock 106 off the barrel 102. Conversely, a user
may mount the forestock 106 to the marker 100 by sliding the
forestock 106 over the barrel 102 such that the holes 111 in the
forestock 106 and the holes 113 in the receiver 104 are aligned.
The pins 108 and 110 may then be moved through the forestock 106
and receiver 104 to couple the forestock 106 to the receiver 104.
As best seen in FIG. 7, the pins 108 and 110 may include a bias
member 105 to prevent accidental removal of the pins 108 and 110.
Although the first pin 108 and second pin 110 are shown for
purposes of illustration, it should be appreciated that other quick
connections may be used to couple the forestock 106 to the receiver
104.
[0061] In some cases, the forestock 106 may be associated with a
barrel adapter 109. The barrel adapter 109 (best seen in FIG. 10A)
allows a user to configure the marker 100 with barrels of different
diameters. Consider a situation in which a user desires to use
barrels with either a 7/8 inch diameter or a 1 inch diameter. The
bore 107 could be dimensioned to receive the 1 inch barrel. If the
7/8 inch barrel is desired to be used, the user would place the
barrel through the adapter 109. In this example, the opening in the
adapter 109 would be dimensioned to receive the barrel, which is
7/8 inches in this example. The outer diameter of the adapter 109
would be dimensioned to be received by the bore 107, or 1 inch in
this example. As shown, the adapter is received in a recess 115
formed in the forestock 106.
[0062] In some embodiments, the forestock 106 may include a bottom
rail 112, a side rail 114, and/or a top rail 116 for mounting
accessories, such as sites, scopes, etc. In the example shown, the
marker 100 includes a front site 118 mounted to the top rail 116.
It should be appreciated that the marker 100 could be customized
with other types of sites, such as those shown in FIGS. 21A-21B. By
way of a further example, a vertical handle, such as shown in FIG.
22, could be attached to the bottom rail 112.
[0063] Preferably, the user may select between a plurality of
interchangeable forestocks, which each allow a suitable quick
connection with the receiver 104 to customize the marker 100. For
example, if the receiver 104 includes holes 113, each of the
forestocks could include holes 111 to allow a quick connection
using pins 108 and 110. Example forestocks that could be used with
the marker 100 are illustrated in Figures 19A-19E. It should be
appreciated that other styles of forestocks could be used with the
marker 100.
[0064] In some embodiments, the marker 100 may include a tool box
120 for storing one or more items. In this embodiment, the tool box
120 is coupled with and extends from the receiver 104. Typically,
the tool box 120 is detachably coupled with the receiver 104;
however, the tool box 120 could be integral with or permanently
affixed to the receiver 104. Embodiments are also contemplated in
which the tool box 120 could be an internal storage compartment in
the receiver 104 that could be accessed by a user.
[0065] Preferably, the tool box 120 resembles a magazine that feeds
projectiles into the receiver. Instead of feeding projectiles into
the receiver 104, however, the tool box 120 would typically hold
tools for maintaining the marker 100, including but not limited to
hex wrenches or a tube of oil. As shown, the tool box 120 includes
a slot 122 dimensioned to receive a first supply line 124. In other
embodiments, the tool box 120 could include a connection for
coupling the first supply line 124. Preferably, the first supply
line 124 provides a source of compressed gas for a valve
arrangement 178 within the marker 100 (see FIG. 13). In some cases,
if the marker 100 were a combustible fuel powered marker, the first
supply line 124 may provide a supply of fuel, such as propane, to a
combustion chamber within the marker 100.
[0066] The tool box 120 may include an internal storage compartment
for storing items, such as tools. In the example shown in FIG. 12,
the tool box 120 includes a first side 130 and a second side 132
pivotally coupled with a bottom 134. Although the embodiment shown
includes an open top, the tool box 120 may be entirely closed since
projectiles are not fed into the receiver 104 from the tool box 120
in this embodiment.
[0067] As shown, the tool box 120 includes a first hinge 136 and a
second hinge 138 that allow the first side 130 and second side 132
to pivot, respectively. In this example, the hinges 136 and 138 are
living hinges, but separate hinges could be coupled with the sides
130 and 132 and bottom 134 in some cases. It should be appreciated
that other pivotal connections could also be used. Although this
example shows the tool box 120 hinged at the bottom 134, it should
be appreciated that the tool box 120 could be hinged at the sides
130 and 132 or the top or not hinged at all.
[0068] In some cases, the tool box's 120 interior may include tool
holders configured to receive a specific arrangement of tools (or
other items). In the example shown, the tool box 120 includes slots
140 dimensioned to receive hex wrenches 142 in the first side 130
of the tool box 120. The second side 132 includes complementary
ridges 144 configured to close the slots 140 when the tool box 120
is closed, thereby holding the wrenches 142 in place. In this
example, the first side 130 of the tool box 120 also includes an
area for a tube of oil 146 that could be used to maintain the
marker 100. It should be appreciated that the internal cavity of
the tool box 120 could be configured to hold a variety of tools,
accessories, or other items.
[0069] In the example shown, the tool box 120 includes an opening
143 dimensioned to receive an internal latch 145 when the tool box
120 is closed. In this example, the tool box 120 includes an
opening 147 dimensioned to receive a latch mechanism in a tool box
mount 121 for detachably coupling the tool box 120 to the receiver
104.
[0070] Referring again to FIGS. 1-9, the marker 100 preferably
includes a tool box mount 121 configured to receive the tool box
120. As shown, the tool box mount 121 includes a release button 123
(best seen in FIG. 5) that controls a latch mechanism associated
with the tool box mount 121. In the example shown, the latch
mechanism engages the opening 147 in the tool box 120 to
selectively release the tool box 120 from the tool box mount 121.
It should be appreciated that a variety of mechanisms could be used
to detachably couple the tool 120 with the tool box mount 121, such
as an interference fit, frictional fit, magnets, etc.
[0071] In the example shown (as best seen in FIG. 2), the tool box
mount 121 is coupled with the receiver 104 using an interference
fit. As shown, the receiver 104 includes ridges 129 that extend
from the receiver 104. The top portion of the tool box mount 121
includes grooves 125 formed in a flange 127 that are configured to
receive the ridges 129. To couple the tool box mount 121 to the
receiver 104, the user would align the grooves 125 with the ridges
129, such that the ridges 129 extend through the grooves 125. The
tool box mount 121 may then be moved toward the barrel 102 in the
example shown such that the flange 127 creates an interference fit
with the ridges 129. The user may detach the tool box mount 121 by
moving the tool box mount 121 in an opposite direction (away from
the barrel 102 in this example) until the ridges 129 are aligned
with the grooves 125. Other mechanisms, such as a frictional fit,
could also be used to couple the tool box mount 121 with the
receiver 104.
[0072] Preferably, a plurality of interchangeable tool boxes and
tool box mounts may be provided to allow customization of the
marker 100. Typically, each of the tool boxes includes an interior
cavity for storing items, such as tools. Examples of tool boxes
that resemble magazines of types used for feeding projectiles into
the receivers of actual firearms are shown in FIGS. 20A-20E. It
should be appreciated that other styles could also be provided. The
tool box 120 may be formed from a variety of materials, including
but not limited to plastic, aluminum and magnesium.
[0073] The marker 100 may include a grip assembly 146. In the
example shown, the grip assembly 146 includes a grip 148 that is
dimensioned for a user to grasp. The grip assembly 146 includes a
trigger 150 for actuation by the user to fire the marker 100. The
trigger 150 may mechanically and/or electrically selectively fire
the marker 100. In the example shown, the trigger 150 is surrounded
by a trigger guard 152. As shown, the marker 100 includes a safety
154. In the position shown in FIG. 1, the safety 154 prevents the
marker 100 from firing; if moved to a fire position, the safety 154
allows the marker 100 to fire projectiles. Although the example
shown includes a lever for actuating the safety 154, it should be
appreciated that other forms of safety could be used.
[0074] In some embodiments, the grip assembly 146 may be detachably
coupled with the receiver 104. As shown, the grip assembly 146
includes a hole 155 that is alignable with a hole 157 in the
receiver 104 through which a pin 156 may be received. By removing
the pin 156 (and the lower pin 170), the grip assembly 146 may be
detached from the receiver 104. In the example shown, the lower
portion of the grip 148 includes an adaptor 158 configured to
receive a propellant source, such as a canister of carbon dioxide
or nitrogen. As discussed below, the adaptor 158 and first supply
line 124 are optional, depending on whether the rear stock attached
to the receiver 104 includes an internal passageway 186 for
connection to a propellant source (See FIGS. 15-16).
[0075] In the example shown, a picatinny rail 160 is attached to a
top portion of the receiver 104. The picatinny rail 160 may be used
to add risers, sites, handles, or other items to the receiver 104.
As shown, a rear sight 161 is coupled to the picatinny rail 160. By
way of another example, carry handles, such as shown in FIGS.
21C-21D, could be mounted to the picatinny rail 160.
[0076] In the embodiment shown, the marker 100 includes a hopper
162 for holding a plurality of projectiles to be fired. As shown,
the hopper 162 includes a lid 164 pivotably mounted to the hopper
162 to selectively open/close an opening to the hopper 162.
Preferably the hopper 162 has a low profile to reduce the target
area of the user and allow a better line of site to fire the marker
100. By way of example only, the hopper 162 may have a length that
is more than three times its height in some cases (see FIG. 3). As
shown, the hopper 162 is offset from the receiver 104 to allow a
better line of site for the user to fire the marker 100. However,
the hopper 162 could be coupled to the receiver 104 on the top
(e.g., picatinny rail 160) or other location of the receiver
104.
[0077] In some cases, the hopper 162 may be coupled with a feed
mechanism 166 that feeds projectiles into the receiver 104. An
example feed mechanism that could be used with the marker 100 is
shown in U.S. Pat. No. 6,739,323, which is incorporated herein by
reference.
[0078] Instead of a separate feed mechanism, the hopper 162 may
include an integral feed mechanism in some embodiments. For
example, the hopper 162 may be an agitating or force-fed hopper. In
some cases, the projectiles may be gravity fed into the receiver
104. For example, the lower portion of the hopper 162 may include a
passage that is coupled directly with the receiver 104, so that
projectiles may be fed one-by-one through the passage into the
receiver 104. In some embodiments, the receiver 104 (or other
portion of the marker 100) may include an internal cavity for
receiving a plurality of projectiles. By way of another example,
the receiver 104 may be stick fed with projectiles.
[0079] In the embodiment shown in FIGS. 1-9, the marker 100
includes a detachable end cap 168. If the user desires to have a
rear stock, the end cap 168 may be removed and a rear stock coupled
to the receiver 104 (see FIGS. 14-16). In the example shown, pins
170 pass through projections 172 (see FIGS. 2 and 13) in the end
cap 168 and holes in the receiver 104 and grip assembly 146.
Removal of the pins 170 allows the user to detach the end cap 168
from the receiver 104. In the example shown, the end cap 168
includes an optional ring 174 that user may grasp to remove the end
cap 168. As discussed below, a plurality of interchangeable rear
stocks may be substituted for the end cap 168 to customize the
marker 100. Preferably, each of the rear stocks include similarly
arranged holes such that the rear stocks may be attached to the
receiver 104 using the pins 170. Examples of rear stocks that could
be used with the marker 100 are shown in FIGS. 18A-18C.
[0080] Referring now to FIG. 13, there is shown a detailed
cross-sectional view of the marker 100. As shown, a sear 188 is
interposed between the trigger 150 and a 190. In this example, the
sear 188 is disposed on pivot pin 192 and is biased by spring 194
toward engagement of the rear bolt 190. When the marker 100 is in
the cocked position, actuation of the trigger 150 releases the rear
bolt 190 from the sear 188. In the example shown, the marker 100 is
in the cocked position when the rear bolt 190 is in a rearward
position in which the sear 188 prevents forward movement of the
rear bolt 190. In the example shown, the marker 100 moves to a
discharge position by releasing of the rear bolt 190 from the sear
188 due to user actuation of the trigger 150. It should be
appreciated that other trigger assemblies, both mechanical and
electrical, may be suitable to selectively fire the marker 100 and
are contemplated herein.
[0081] In the example shown, the rear bolt 190 moves under the bias
of drive spring 196 upon actuation of the trigger 150. A pin 198 is
disposed within the spring 196 in the example shown. The rear bolt
190 is coupled to a front bolt 200 via a linkage arm 202 in the
example shown. This causes concomitant movement of the front bolt
200 with the movement of the rear bolt 190. The front bolt 200 is
adapted to push a projectile into the barrel 102 during firing.
[0082] The bias of drive spring 196 on rear bolt 190 causes rear
bolt 190 to depress an impact pin 204 on the valve assembly 178,
which causes the valve assembly 178 to release a quantity of
compressed gas, thereby causing a projectile to be propelled out
the barrel 102. Another quantity of compressed gas may be released
on the side of valve assembly 178 in which the rear bolt 190 is
disposed, which will recoil the rear bolt 190 to the cocked
position. Example valve arrangements and firing mechanisms that
could be used are shown and described in U.S. Pat. Nos. 4,189,609,
5,722,383, and 6,550,468, which are each hereby incorporated by
reference.
[0083] In the embodiment shown, a second supply line 176 can be
seen. Preferably, the marker 100 may be configured such that either
the first supply line 124 or the second supply line 176 may supply
the valve arrangement 178 with a propellant with which the
projectiles may be fired. Preferably, the first supply line 124 or
the second supply line 176 provides compressed gas, such as carbon
dioxide or nitrogen, to the valve arrangement 178. As discussed
above, however, the supply lines 124 or 176 could provide fluid
communication with a supply of combustible fuel in some
embodiments.
[0084] In this example, the marker 100 includes a coupling 180
associated with the first supply line 124. Typically, the user
would choose between the first supply line 124 and the second
supply line 176. If the user decided to use the first supply line
124, the user would put the first supply line 124 and coupling 180
associated with the first supply line 124 into the receiver. This
would supply compressed gas to the valve arrangement 178 via the
first supply line 124. A passageway is defined in the receiver 104
for receiving the second supply line 176. Preferably, the
passageway extends from the valve arrangement to the rear portion
of the receiver 104 so that the second supply line 176 may be
aligned with a passage with a rear stock which is in fluid
communication with a supply of compressed gas. If the user desired
to use the second supply line 176, the first supply line and
associated coupling 180 would typically be removed and the second
supply line and an associated coupling 180 inserted into the
passageway. The coupling 180 provides the valve arrangement 178
with a supply of compressed gas from the first supply line in the
example shown.
[0085] In some cases, the coupling 180 may be configured to receive
both the first supply line 124 and the second supply line 176. For
example, the coupling 180 may include a first check valve (not
shown) at the inlet of the first supply line 124 into the coupling
180 and a second check valve (not shown) at the inlet of the second
supply line 176 into the coupling 180. With this arrangement, the
inlets would only be open due to the supply of compressed gas to
open a respective check valve. It should be appreciated that other
mechanisms, both mechanical and electrical, could be used to
selectively supply the valve arrangement 176 with a flow of
compressed air from either the first supply line 124 or the second
supply line 176. In some embodiments, the coupling 180 could be
configured to supply compressed air from both the first supply line
124 and the second supply line 176. In the example shown in FIG.
13, the second supply line 176 does not supply compressed gas to
the valve arrangement 178 due to the end cap 178 being connected to
the receiver 104. As discussed below, the second supply line 176
may continue flow through the rear stock, which may be connected
with a source of compressed gas.
[0086] FIG. 14 shows an example in which a rear stock 182 has been
coupled with the receiver 104. In the example shown, the rear stock
182 includes a projection 184 with holes dimensioned to receive the
pins 170. Accordingly, a user may customize a marker 100 with a
plurality of interchangeable rear stocks that may be coupled to the
receiver 104. Examples of rear stocks that may be coupled to the
marker 100 are shown in FIGS. 18A-18C. It should be appreciated
that other types of rear stocks could also be provided.
[0087] FIGS. 15-16 show the example embodiment of FIG. 14 with the
rear stock 182 shown in sectional view. As shown, the rear stock
182 includes a passageway 186 that is in fluid communication with
the second supply line 176. The passageway 186 may be in fluid
communication with the supply of compressed gas (or other
propellant), thereby providing compressed gas to the valve
arrangement 178. In some cases, the rear stock 184 may include a
recess 205 for receiving an end of the pin 198.
[0088] FIG. 17 shows the right half of an example receiver 104.
Although the example receiver 104 shown includes holes that could
be used for quick connections of rear stocks, fore stocks, etc.,
this receiver 104 could also be used with a marker without such
customization features. In some cases, the valve assembly 178 may
be tapped to supply compressed gas for other functions associated
with the marker 100. For example, the feed mechanism 166 could be
pneumatically actuated with compressed gas tapped off the valve
assembly. For example, U.S. Pat. No. 6,739,323 shows a feed
mechanism that may be pneumatically actuated. By way of another
example, U.S. Pat. No. 6,550,468 shows a trigger assist that may be
pneumatically actuated. In receivers formed by two halves that are
connected together, such as the example half shown, gas that is
tapped off the valve assembly 178 tends to escape through the seam
between the halves of the receiver 104.
[0089] In the example shown, the receiver 104 includes a groove 206
dimensioned to receive a seal 208, such as an O-ring. Preferably,
the groove 206 is substantially elliptical is shape, which retains
the seal 208 without a fastener or adhesive. The groove 206 and
seal 208 are disposed within the receiver 104 preferably adjacent
the portion of the valve assembly 178 that is tapped to prevent
escape of gas through the seam in the receiver 104. As shown, a
first outlet port 210 and a second outlet port 212, which are
associated with tapped portions of the valve assembly 178, are
disposed within the groove. Additionally outlet ports (or a single
outlet port) may be provided.
[0090] FIGS. 23-27 show a grip assembly 214 according to an
alternative embodiment, which uses electronics (at least in part)
to actuate firing of the marker 100. Referring to FIG. 23, the grip
assembly 214 includes a grip 216 that is dimensioned for a user to
grasp. As discussed below, the electronics (and related components)
for controlling actuation of the marker 100 are disposed within the
grip 216. The grip assembly 214 includes a trigger 218 for
actuation by the user to fire the marker 100. In the example shown,
the trigger 218 is surrounded by a trigger guard 220. As shown, the
lower portion of the grip 216 includes an adaptor 222 configured to
receive a propellant source, such as a canister of carbon dioxide
or nitrogen. As discussed above, the adaptor 222 may be optional,
depending on the type of rear stock attached to the receiver
104.
[0091] In this example, the grip 216 includes a battery door 224
that may be removed to provide access to a battery associated with
the electronics (and possibly other components internal to the grip
216). Although the battery door 224 extends longitudinally along
the rear portion of the grip 216 in the example shown, it should be
appreciated that the battery door 224 could be located elsewhere on
the grip 216 depending on the circumstances. As shown, the battery
door 224 includes a clasp 226 for detachable coupling with the
battery door 224. It should be appreciated that other mechanisms
could be used for selectively opening/closing the battery door 224
to the rear portion of the grip 216.
[0092] In the embodiment shown, the grip assembly 214 includes a
mode selector 226 for selecting among multiple firing modes. The
term "firing mode" is intended to be broadly construed to include a
safety position in which the marker 100 is prevented from firing,
as well as modes that in the marker 100 are allowed to fire. In
this example, the mode selector 226 includes a lever 228 for
rotating the mode selector 226 between different firing modes. In
the example shown, a mode indicator 230 aligns with the selected
firing mode. As shown, the mode indicator 230 specifies that a
first mode 232 is selected. By rotating the mode selector 226, a
second mode 234 or a third mode 236 could be selected. As shown, an
end of the lever 228 defines an opening 238 for receiving detents
240 to retain the mode selector 226 in the selected mode. Although
a rotary mode selector 226 is shown for purposes of example, it
should be appreciated that other non-rotating mode selectors, such
as a linearly-moving lever, could be used. Although the embodiment
shown includes three modes, it should be appreciated that
embodiments are contemplated with only two modes; additionally,
embodiments are contemplated with more than three modes.
[0093] FIGS. 24-26 show cross-section views of the example grip
assembly 214 shown in FIG. 23. Unlike the embodiment described
previously with respect to FIG. 13, there is no contact between the
trigger and sear in the embodiment shown. Instead, a controller
circuit electronically detects movement of the trigger and actuates
movement of the sear to fire the marker 100. In some embodiments,
the manner by which the controller circuit controls movement of the
sear could depend upon the firing mode and/or other firing
characteristics selected by the user.
[0094] In the embodiment shown, a sear 242 pivots about a pivot pin
244 and the rear section (right portion in FIG. 24) is urged upward
(in this example) by a biasing member 246. A depending portion 248
of the sear 242 extends toward a position adjacent a linear
actuator 250, such as a solenoid. In the embodiment shown, the
depending portion 248 is unitary with the sear 242; however,
embodiments are contemplated in which the depending portion 248 and
the sear 242 could be separate components that are coupled
together. As shown, a rod 252 of the linear actuator 250 moves
between a retracted position and an extended position (shown). When
the rod 252 moves to the extended position, this pushes the
depending portion 248 away from the linear actuator 250, which
rotates the sear 242 (clockwise as shown) to fire the marker 100.
For example, this movement of the sear 242 could release the rear
bolt 190, which causes firing of the marker 100. In other
embodiments, such as using combustible gas, this movement of the
sear 242 could be used to initiate ignition in a combustion
chamber.
[0095] A controller 254 controls movement of the rod 252 responsive
to movement of the trigger 218. The controller 254 could be a
microcontroller, for example, that is programmed to perform the
functions described herein. Other electronic components, such as a
capacitor 255, could be associated with the controller. FIG. 27 is
a simplified schematic representation showing possible inputs and
outputs for the controller 254, according to an embodiment, which
will be described below.
[0096] Referring again to FIGS. 24-26, the controller 254
determines when the trigger 218 is pulled by using one or more
proximity sensors to detect the position of the trigger 218.
Although the embodiment described below uses magnetic sensors,
embodiments are contemplated in which other types of proximity
sensors could be used, including but not limited to optical
sensors, capacitive sensors, and inductive sensors.
[0097] In the example shown, a magnet 256 is associated with the
trigger 218 that moves concomitant with the trigger 218. As shown,
the magnet 256 is embedded in the trigger 218; however, embodiments
are contemplated in which the magnet could be coupled with the
trigger 218, such as using a fastener or adhesive. One or more
magnetic sensors, such as Hall effect sensors, may be provided to
detect the trigger's 218 position by detecting the magnetic flux
associated with the magnet 256.
[0098] For example, in the embodiment shown, the magnet 256 is
oriented to move between a first trigger detector 258 and a second
trigger detector 260 when the trigger is pulled (as best seen in
FIG. 26). With this arrangement, the controller 254 actuates the
rod 252 to the extended position when both the first trigger
detector 258 and the second trigger detector 260 sense the magnetic
field of the magnet 256. Typically, the first trigger detector 258
and the second trigger detector 260 are Hall effect sensors. With
such an arrangement, the trigger detectors 258 and 260 will switch
on (output changing from low to high or visa versa) when the
magnetic flux density increases above a threshold level, which
indicates to the controller 254 that the trigger 218 has been
pulled. In response, the controller 254 will actuate the rod 252 to
the extended position, thereby moving the sear 242. When the
magnetic flux density decreases below a threshold level, the
trigger detectors 258 and 260 will switch off (output changing from
high to low or visa versa), which indicates to the controller 254
that the trigger 218 has been released. The controller 254 will
move the rod 252 to the retracted position. Typically, the rod 252
is held in the extended position for a pre-determined period of
time, not dependent on the amount of time the trigger 218 is
pulled.
[0099] In some embodiments, at least one of the first trigger
detector 258 and the second trigger detector 260 are unipolar Hall
effect sensors. By using a unipolar Hall effect sensor, safety
advantages are provided because a specific magnetic orientation
would be required to fire the marker 100, which reduces the
possibility that external magnets would inadvertently cause the
marker 100 to fire. For example, consider an example in which the
first trigger detector 258 is a unipolar Hall effect sensor that
switches on in response to a south pole and the second trigger
detector 260 is an omnipolar Hall effect sensor that switches on in
response to either a north pole or a south pole. In this example,
the magnet 256 would be oriented on the trigger 218 such that the
south pole would be exposed to the first trigger detector 258 when
the user pulls the trigger 218. With this type of arrangement, the
magnet 256 could include a pole indicator printed on a side, such
as text or a graphic, for maintenance purposes if the user needed
to replace the magnet 256 so that the correct orientation could be
determined.
[0100] In some embodiments, a magnet 262 is associated with the
mode selector 226 that moves concomitant with rotation of the mode
selector 226. The magnet 262 may be embedded in the mode selector
226 coupled with the mode selector 226 using a fastener, adhesive,
or otherwise associated with the mode selector 226. In the
embodiment shown, a mode detector 263 is provided to detect the
position of the mode selector 226. For example, the mode detector
could be a magnetic sensor, such as a Hall-effect sensor, to detect
the mode selector's 226 position by detecting the magnetic flux
associated with the mode selector 226. This allows the controller
254 to determine the firing mode selected by the user. Other
embodiments are contemplated in which other types of electronics
could be used to select the firing mode, including but not limited
to tactile switches, optical-electronics, momentary switches,
push-button switches, rotary switches, and capacitive sensors.
[0101] In the embodiment shown, the grip assembly 214 includes a
user interface 264 and a status indicator 266 on an end of the grip
216 opposite the battery door 224. As shown, a first opening 268
provides access to the user interface 264, while a second opening
270 exposes the status indicator 266. In the example shown, the
user interface 264 is a momentary push-button switch; however,
other embodiments are contemplated in which other suitable
switches, knobs, etc., could be used. Although the status indicator
266 will be described herein as a LED with multiple colors (e.g.,
red/green/orange), it should be appreciated that other mechanisms,
such as audible alerts, a LCD display, etc., would be suitable to
provide information to the user regarding the marker 100.
[0102] The user interface 264 allows the user to turn off the
electronics. For example, pushing the user interface 264 for
greater than a specific time, such as two seconds, could turn off
the electronics. The status indicator 266 could be used to let the
user know that the electronics is turned off. For example, the
status indicator could light up red when the user has pushed the
user interface for a sufficient period to turn off the
electronics.
[0103] Additionally, the user interface 264 can be used to adjust
the manner by which the marker 100 fires. For example, the user
interface 264 could allow the user to select the default firing
mode associated with modes 234 and 236. Consider an example in
which the user pushes the user interface 264 for approximately 0.5
seconds (or another predetermined time) and releases the user
interface 264, then the status indicator 266 starts flashing orange
(or other color). In this example, the status indicator could flash
a number of times corresponding with default firing mode. By way of
example only, the firing modes could be: (1) safe three-round
burst--pulling the trigger three times in less than a second will
result in a 3-shot burst; (2) safe full-auto--pulling the trigger
three times in less than a second will result in full-automatic
firing; (3) auto-response--firing upon both pulling and releasing
the trigger; (4) turbo mode--pulling the trigger three times in
less than one second will result in full-automatic firing at a rate
of 15 bps (or other pre-determined rate); (5) semi-auto--firing
each time the trigger is pulled. In this example, the user will
know that the marker 100 is set to the safe full-auto mode as the
default firing mode if the status indicator 266 flashes twice. It
should be appreciated that the firing modes listed above are
provided for example purposes only and are not intended to limit
the types or number of firing modes that could be used.
[0104] In some embodiments, the user can change multiple
characteristics by which the marker 100 fires. Consider an example
in which four characteristics of the marker 100 could be changed:
(1) dwell--the amount of time that the linear actuator 250 is
powered during a trigger pull; (2) debounce--the minimum amount of
time between accepted trigger pulls; (3) rate-of-fire; and (4)
default firing mode. By way of example only, the user could enter a
programming mode to change one or more of these characteristics by
simultaneously pushing the user interface 264 and the trigger 218
for a predetermined period of time.
[0105] Once in the programming mode, the status indicator 266 could
indicate the particular characteristic selected to be changed. By
way of example only, the status indicator 266 could indicate the
selected characteristics as follows: (1) solid red--dwell; (2)
solid green--debounce; (3) flashing green--rate-of-fire; and (4)
alternating red/green--default firing mode. In some embodiments,
the user could cycle between these characteristics using the
trigger 218. In this example, the status indicator would cycle from
solid red (dwell) to solid green (debounce) when the trigger 218 is
pulled and then from solid green (debounce) to flashing green
(rate-of-fire) when the trigger 218 is pulled again and then from
flashing green (rate-of-fire) to alternating red/green (default
firing mode) if the trigger 218 is pulled again. To select a
particular characteristic to change, the user could pull and hold
the trigger for a predetermined time, for example. When this is
done, the status indicator 266 could flash the current value
selected for the characteristic. If the user selected debounce, for
example, the status indicator 266 could flash 30 times if the
debounce value had been set to 30 milliseconds.
[0106] To enter a different value, the user could pull the trigger
the number of times needed to select the desired value. Consider an
example in which the user selected the dwell characteristic to
change. In this example, the default dwell value could be 8
milliseconds and may be adjusted between 2-20 milliseconds. If the
user wanted to change the dwell value to 10 milliseconds, the user
would pull the trigger 10 times. Once the user has entered the
desired value, the status indicator 266 could flash (or otherwise
indicate) that the value is accepted and stored.
[0107] Consider another example in which the user selected the
debounce value to change. In this example, the default debounce
value could be 52 milliseconds and may be adjusted between 25-65
milliseconds. If the user wanted to change the debounce value to 25
milliseconds, for example, the user would pull the trigger 25
times. Once the user has entered the desired value, the status
indicator 266 could flash (or otherwise indicate) that the value is
accepted and stored.
[0108] Consider a further example in which the user selected the
rate-of-fire value to change. In this example, the default
rate-of-fire value could be 13 balls per second and may be adjusted
between 8-30 balls per second. If the user wanted to change the
rate-of-fire value to 20 balls per second, for example, the user
would pull the trigger 20 times. Once the user has entered the
desired value, the status indicator 266 could flash (or otherwise
indicate) that the value is accepted and stored.
[0109] Consider another example in which the user selected the
firing mode value to change. In this example, the firing mode value
could be 2, which could correspond to safe full-auto. If the user
wanted to change the firing mode to auto-response, which
corresponds to a firing mode value of 3 in this example, the user
would pull the trigger 3 times. Once the user has entered the
desired value, the status indicator 266 could flash (or otherwise
indicate) that the value is accepted and stored.
[0110] FIGS. 28-46 illustrate an example paintball marker 300
constructed according to another embodiment of the present
invention. In this embodiment, the marker 300 can fire in either a
mechanical firing mode or an electronically-assisted firing mode,
depending on the firing mode selected by the user. FIGS. 32-35 show
various views of the marker 300 in the mechanical firing mode and
FIGS. 36-41 show various views of the marker 300 in the
electronically-assisted firing mode. One advantage of this
embodiment is the ability to continue firing the marker 300 in the
mechanical firing mode even after the power source for the
electronically-assisted firing mode is drained and can no longer
sufficiently power the electronics.
[0111] FIG. 28 is a left side view of an example paintball marker
300. In this example, the marker 300 has three modes that can be
selected by the user: a safe mode 302 that prevents the marker 300
from firing, a mechanical firing mode 306 in which a mechanical
launch assembly actuates launching of projectiles without the aid
of electronics, or an electrically-assisted firing mode 308, which
could be programmed in a manner that changes various firing
characteristics. The term "electronically-assisted firing mode" is
intended to mean a firing mode in which an electronic circuit is
used to initiate firing of a projectile. As shown in FIG. 28, the
safe mode has been selected, which prevents the marker 300 from
firing even if the trigger 304 is pulled. Although three modes are
shown in this example, it should be appreciated that additional
modes could be provided if desired. In the example shown, the
marker 300 includes a mode selector 301 from which the user may
select a desired mode. Although the mode selector 301 rotates
between modes 302, 306, and 308 in the example shown, it should be
appreciated that other manners of selecting a mode could be
provided. Additionally, the order and position of the various modes
could be changed if desired. Also in this view, a gauge port 310
(detailed view in FIG. 44) can be seen which allows a pressure
gauge to be inserted to be received to provide a readout of
internal pressure within the marker 300. Although pressure gauges
associated with markers are known, an embodiment of the marker 300
allows the pressure gauge to be removed when not needed. A
removable pressure gauge allows the marker 300 to be tested and for
maintenance purposes. When not needed, the pressure gauge can be
removed and replaced with a plug that prevents escape of gas so the
marker is more rugged and authentic looking.
[0112] FIG. 29 is a right side view of the example marker 300 shown
in FIG. 28. In this view, a velocity selector 312 extends from the
right side of the receiver to allow a user to adjust the velocity
from which the projectiles are propelled out of the marker 300.
Although the velocity selector 312 is shown on the right side of
the marker 300 in this example, it should be appreciated that it
could be located in other positions on the marker 300. In this
example, the user would rotate the velocity selector 312 in one
direction for greater velocity while rotating it in the opposite
direction to reduce the velocity of projectiles.
[0113] FIGS. 30 and 31 are left side views of the example marker
shown in 28 with a portion of the body removed to show internal
components. In this view, a portion of the valve arrangement 322 is
shown. The valve arrangement 322 is actuated (i.e., opened to vent
gas) using a lever 326 in this example. The lever 326 pivots about
a pin 328 with a first arm 332 and a second arm 334. The first arm
332 is movable toward and away from an input valve 330. In this
example, when the input valve 330 is actuated by the first arm 332
of the lever 326, this causes the valve arrangement 322 to vent a
supply of compressed gas to propel a projectile. In this example,
the lever 326 can be actuated in two ways, either mechanically
(corresponding to the mechanical mode 306) or electronically
(corresponding to the electronically-assisted mode 308).
[0114] When in the mechanical mode 306, the lever 326 is actuated
using a cam surface 324 on the trigger 304. Movement of the trigger
304 (i.e., when the user pulls the trigger) causes movement of the
cam surface 324 to rotate (counter-clockwise in this example) the
lever 326 such that the first arm 332 actuates the input valve 330
(pushes the input valve 330 in this example). When in the
electronically-assisted mode 308, a rod 336 of a linear actuator
338, such as a solenoid, moves between a retracted position and an
extended position. When the user pulls the trigger 304, the rod 336
moves to the extended position, which pushes the second arm 334 of
the lever 326 and rotates (counter-clockwise in this example) the
lever 326. This rotation of the lever 326 causes the first arm 332
to actuate the input valve 330 (pushes the input valve 330 in this
example) to vent gas and propel a projectile. In the embodiment
shown, the mode selector 301 allows a longer trigger stroke in the
mechanical mode than in the electronically-assisted mode. In other
words, the mode selector 301 is configured to block the trigger
from making as long of a stroke when the electronically-assisted
mode is selected. This shorter trigger stroke prevents the cam
surface 324 on the trigger from actuating the lever 326, which
would result in a double shot--one shot from the
electronically-assisted mode and the other from the mechanical
mode.
[0115] In this view, a cross-section of the mode selector 301 can
be seen. As shown in this example, the mode selector 301 includes a
notch 314 that is dimensioned to receive a tip extending from the
trigger 304. In this example, which shows the mode selector 301 in
safe mode, the notch 314 is not aligned with the tip 316 of the
trigger 304. This prevents the trigger 304 from being sufficiently
pulled to trip the lever 326, thereby preventing firing of the
marker 300 in safe mode.
[0116] FIGS. 32-34 show example views of the marker 300 from FIG.
28 in the mechanical firing mode 306. As discussed above, in this
example, the mechanical firing mode allows the marker to fire
projectiles without the aid of electronics. This allows the marker
300 to be fired even if the battery (or other energy source) is
sufficiently drained to no longer power the electronics. In FIG.
34, it can be seen that the mode selector 301 has been rotated to
the mechanical mode 306, which aligns the tip 316 with the notch
314 in the mode selector 301, thereby allowing the tip 316 to be
received therein when the trigger 304 is pulled. An example trigger
pull is shown in FIGS. 35-36. As best seen in FIG. 36, pulling the
trigger 304 registers the tip 316 in the notch 314, which allows
the cam surface 324 to move the first arm 332 of the lever 326 to
actuate the input valve 330, thereby venting gas from the valve
arrangement 322 to propel a projectile.
[0117] FIGS. 37-39 show example views of the marker 300 in the
electronic-aided firing mode 308. As discussed above, the mode
selector 301 is associated with a magnet 340 (best seen in FIGS.
42-43) that turns on the electronics when the mode selector 301 is
positioned in the electronically-assisted mode 308 due to one or
more magnetic sensors, such as Hall effect sensors, associated with
the electronics. Even though the tip 316 is not aligned with the
notch 314, pulling of the trigger 304 provides movement of one or
more magnets 318 associated with the trigger 304 such that one or
more magnetic sensors 320 can detect movement of the trigger 304
and actuate electronics to actuate the valve arrangement 322. FIGS.
40-41 show an example with the trigger pulled which causes the
electronics to actuate the valve arrangement 322. As discussed
above, detection by the magnetic sensors 320 causes the electronics
to actuate the rod 336 of the linear actuator 338, which rotates
the lever 326. This causes movement of the first arm 332, which
actuates the input valve 330, thereby venting the valve arrangement
322 to propel a projectile. As discussed above, the electronics
could be programmed to alter various firing characteristics.
[0118] FIGS. 45-46 show an embodiment of the velocity adjustment.
In this example, the velocity selector 312 includes a threaded
portion that causes linear movement of the velocity selector 312,
which adjusts a spring 342 in the valve arrangement 322 to increase
or decrease the spring strength, thereby adjusting the regulated
pressure going into the valve arrangement 322.
[0119] Although the present disclosure has been described with
reference to particular means, materials and embodiments, from the
foregoing description, one skilled in the art can easily ascertain
the essential characteristics of the invention and various changes
and modifications may be made to adapt the various uses and
characteristics without departing from the spirit and scope of the
invention.
