Paintball gun, retrofit kit assembly, and methods of making and
using
Abstract
Paint ball guns frequently break paint balls within the gun.
When this happens the gun is jammed with paint and residue of
broken paint balls, and a user of the gun cannot fire the gun. An
improved paint ball gun includes structures and features which
allow quick opening of the barrel and breach of the gun for
cleaning. After cleaning of the barrel and breach of the gun, the
barrel and gun breach are quickly returned to firing position, and
a user of the gun loses only a few seconds of game time before
being able to resume firing. A kit of retrofit parts, as well as
methods of making and operating the improved paint ball gun are
also disclosed.

Description
FIELD OF THE INVENTION
[0001] The invention relates to a pneumatic marker or paint ball
gun, to such a paintball gun including a breaking breach feature,
to a retrofit kit for converting a conventional paintball gun to
embody the improved structure and operation of this invention, and
to a methods of making and using such a paint ball gun.
BACKGROUND OF THE INVENTION
[0002] Paint ball guns were originally developed for marking
objects at a distance. The guns were employed in such fields as
forestry and cattle ranching, in which frangible projectiles
(generally known as paint balls) were fired against trees to be
harvested, or against cattle to be taken to market, for example.
When the frangible paint ball hits its target, it breaks open and
leaves a brightly colored "paint" mark on the target. For this
reason, the paint ball guns themselves are frequently referred to
as "markers." But, more recently paint ball guns are much more
widely used in various recreational and game environments, such as
simulated war games in which the game players attempt to shoot
opposing players with the paint balls, thus marking this opposing
player with a particular color of paint from a frangible paint
ball. Different colors of paint in the paint balls clearly indicate
paint ball hits, and allow players and teams of players to compete
against one another.
[0003] Paint ball guns using compressed air or gas for power are
well known. Until a few years ago most paint ball guns were
pneumatically-powered, but mechanically-operated guns. The recent
entry into the market of electro-pneumatically operated paint ball
guns provided more consistent and better performing guns for the
recreational market. An electro-pneumatic paint ball gun provides
improved performance with fewer component malfunctions than the
earlier mechanical-pneumatic paint ball guns. However, a common
problem with all paint ball guns, and especially those modern
recreational paint ball guns which have a high cyclic rate of
operation (i.e., a high rate of fire) is the breaking of paint
balls in the gun breach and barrel. That is, the frangible paint
balls inconveniently break in the gun itself, and leave the residue
of the frangible shell of the paint ball and the paint contained in
this shell, within the operating mechanism of the gun. A paintball
gun so fouled is essentially unusable.
[0004] As a result, the user of a fouled paintball gun must
discontinue operation of the gun, and in order to clear the gun of
paint fouling is required to remove the barrel by unthreading it
from the receiver of the gun, then swab it out, as well as cleaning
the breach of the gun. Then the barrel is re-threaded onto the
receiver of the gun. Because unthreading the barrel from the gun
exposes the breach chamber of the gun, cleaning out the barrel
removes most of the paintball residue and paint from the gun, and
allows removal of the remaining paintball residue and paint from
the breach mechanism as well. However, when such a partial
disassembly and cleaning of a fouled paintball gun is necessary
during a game or competition, the player using the gun incurs a
great risk of being hit by opponents, and thus of being put out of
the game.
SUMMARY OF THE INVENTION
[0005] In view of the deficiencies of the related art, it is an
object for this invention to mitigate or eliminate at least one of
these deficiencies.
[0006] Specifically, it is an object for this invention to provide
a paint ball gun having a breach mechanism allowing the gun to
quickly break open at the breach so that the barrel and breach can
be cleared of fouling.
[0007] Another object for this invention is to provide such a
retrofit kit allowing a standard paint ball gun with a threadably
attached barrel to be modified so that the breach will break open,
allowing the barrel to be quickly moved or pivoted aside for
removal of fouling.
[0008] The present invention addresses the deficiencies of the
conventional technology by providing a paint ball gun having a main
body including a grip frame, a trigger, and the main body also
defining a bore for receiving a paint ball. An elongate barrel
secures to the main body and has a breach end receiving the
paintball and a muzzle end from which the paint ball is ejected
forcefully. A bolt assembly is movable in the main body for opening
and closing the breach end of the barrel, and connection structure
attaches the barrel to the main body and has a first position
aligning and sealingly connecting the barrel with the bore and a
second position allowing rapid displacement of the barrel at the
breach end from alignment with the bore so that the breach end of
the barrel is exposed for cleaning.
[0009] A method of using a paint ball gun according to this
invention includes the steps of providing a paint ball gun having a
main body including a grip frame, a trigger, and defining a bore in
the main body for receiving a paint ball. Attaching an elongate
barrel to the main body with a breach end receiving the paintball
and a muzzle end from which the paint ball is ejected forcefully.
Providing a bolt assembly movable in the main body for opening and
closing the breach end of the barrel, and connecting structure
attaching the barrel to the main body and having a first position
aligning and sealingly connecting the barrel with the bore and a
second position allowing rapid displacement of the barrel at the
breach end from alignment with the bore. Whereby in the second
position of the barrel the breach end of the barrel is exposed for
cleaning.
[0010] A retrofit kit for converting a standard conventional paint
ball gun to the advantages of this invention includes a collar
member attachable at the location of the paint ball gun barrel by
use of a tubular adapter which at an aft end replicates the breach
end portion and barrel mounting thread of a paint ball gun barrel.
At a forward end portion the tubular adapter member provides a
flange portion which has a shoulder bearing on the collar member
when tightened. The collar member hingeably carries a hinged
portion, and this hinged portion defines a threaded bore for
receiving a paint ball gun barrel. In a first position the hinged
portion is aligned with the usual position of the paint ball gun
barrel, so that the gun is operational normally. In a second
position of the hinged portion, the paint ball gun barrel swings
aside from its normal position so that the breach is accessible for
cleaning.
[0011] An advantage of the present invention is that a paint ball
gun according to the invention can be quickly cleaned and placed
back into operation after breakage of a paint ball in the breach of
the gun. That is, the breach end of the barrel and the breach area
of the gun itself are accessible when the barrel is moved to its
second location.
[0012] Additional objects and advantages of the present invention
will become apparent to those ordinarily skilled in the pertinent
arts upon reading the following detailed description of a
particularly preferred embodiment of the invention, which
illustrates the best mode contemplated for practicing the
invention, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE EXEMPLARY PREFERRED EMBODIMENTS
[0037] Referring to drawing FIGS. 1-3 in conjunction with one
another, and first considering especially FIG. 1, a paint ball gun
10 includes a main body 12, with a grip frame 14 pivotally carrying
a trigger 16 and defining a trigger guard 18. A barrel 20 is
threadably attached to the main body 12, and defines a breech end
opening (indicated by the arrow 22a-best seen in FIG. 3) at which a
paint ball may be received into the barrel 20. At a muzzle end
opening 22b, the paint ball may be discharged from the barrel
(indicated by the arrow on FIG. 1) by a blast of pressurized gas,
as will be well understood by those ordinarily skilled in the
pertinent arts.
[0038] A gas inlet regulator body 24 is also attached to and
depends from the main body 12, and provides communication via an
inlet 24a (arrowed on FIG. 1) with a source of high pressure gas
(not shown in the drawing Figures) for powering the paint ball gun
10. Also attached to the main body 12 via an upper feed tube 26
defining an opening or feed port 28 may be a paint ball hopper and
feeding device (not seen in the drawing Figures, but indicated by
arrowed numeral 30). The arrowed numeral 30 also indicates the
provision into the feed port or opening 28 of a supply of paint
balls which are fed in one at a time in succession. The feed port
28 opens into a top one 32 (best seen in FIG. 2) of two
substantially parallel and vertically spaced bores (i.e., bores 32
and 34) defined by the main body 12, the lower one of which is
indicated by an arrowed lead line. The lower bore 34 at its forward
end receives an accumulator chamber member 36, as is best seen also
on FIG. 2. The barrel 20 is threadably received at a rear portion
20c thereof (best seen in FIG. 3) into the front of bore 32, at
which the main body 12 defines a barrel-receiving portion 12a. The
barrel 20 is able to receive and discharge paint balls, as
described above.
[0039] A bolt assembly 38 (only a handle portion 38a of which is
fully seen in the drawing Figures) is reciprocally and sealingly
received into the rear portion of bore 32, and cooperates with the
feed port 28 and with the barrel 20 at breech opening 22a to define
a breech chamber 40 (best seen in FIG. 2) in which a paint ball is
sealingly received via feed port 28 and is held preparatory to this
paint ball being forcefully discharged from the gun 10 via barrel
20, viewing FIG. 1. In the drawing Figures, the bolt 38 and handle
portion 38a thereof are illustrated in a rearward one of their two
operative positions, indicating that the bolt is open. When the
bolt handle 38a and bolt 38 move forward to a second operative
position (not seen in the drawing Figures) then the bolt 38 at its
forward extent closes the breach chamber 40 to trap a paint ball
therein preparatory to the paint ball being discharged from the
barrel 20. Discharge of the paint ball is indicated on FIG. 1 by
the arrow exiting muzzle 22b.
[0040] The gas inlet regulator 24 provides pressurized gas (i.e.,
compressed air, or nitrogen, or carbon dioxide, for example) into
the lower bore portion 34. A front part of the bore portion 34
communicates with the accumulator 36 as described above. At the
bore portion 34 (i.e., within the body 12), the paint ball gun 10
includes a discharge valve assembly (not seen in the drawing
Figures) which will be well understood to those ordinarily skilled
in the pertinent arts, including a poppet valve member arranged to
communicating pressurized gas between the bores 32 and 34 in
response to a user of the paint ball gun actuating the trigger 16.
Thus, when a user of the paint ball gun 10 pulls the trigger 16,
the pressurized gas is communicated from accumulator 36 to the
breach chamber 40 and discharges a paint ball via barrel 20.
[0041] Those ordinarily skilled in the pertinent arts will
understand that the grip frame 14 houses an electronic assembly and
valving assembly (also not seen in the drawing Figures). This
electronic assembly and valving assembly typically includes a
3-way, normally-closed solenoid valve and a circuit board (disposed
within the grip frame 14) and including a microprocessor based
control system controlling the operations and timing of the gun
10.
[0042] Further considering now the drawing FIGS. 1-3, it is seen
that in order to allow the barrel 20 to be moved aside to allow
quick cleaning of this barrel and the breach area of the paint ball
gun 10, the front part of main body 12 includes a member or portion
42, which is pivotally or hingeably mounted relative to the
remainder of the main body via a forwardly extending pin 44 carried
by the main body portion 12, and pivotally received in a protruding
boss 46 of the portion 42. Thus, this portion 42 is pivotally or
hingeably movable between a first position, seen in FIG. 1, and a
second position seen in FIG. 2. The portion 42 defines a forward
portion of bore 32, defines barrel thread 12a, and carries the
barrel 20. In its first position, the portion 42 and the barrel 20
are aligned with breach chamber 40, which is defined by a rearward
portion of bore 32 defined within the remainder of main body 12. In
this first position of the portion 42, a seal is established
between the rear face 42a of the portion 42, and the forward face
12b of the main body 12. Most preferably, a sealing member 48 (best
seen in FIG. 2) will be disposed at the surfaces defined by faces
42a and 12b in order to provide a seal between these faces. In the
embodiment seen in FIGS. 1-3, the seal member 48 is disposed in a
groove 48a circumscribing the breach chamber 40 at the opening of
bore 32, although the invention is not so limited. Most preferably,
this seal member 48 may include an O-ring or X-ring type of sealing
member disposed between these faces and circumscribing the bore
32.
[0043] In order to retain the portion 42 in its first position seen
in FIG. 1, while allowing it to be pivoted at will to the second
position seen in FIG. 2, this portion 42 defines a latching bar 50
protruding rearwardly on the side of portion 42 opposite to boss
46. This latching bar 50 is arranged to nest into a pocket
(indicated by arrow 52) defined along the left side of the main
body 12 by the cooperation of a lower boss 54, a pair of vertically
spaced bosses 56a and 56b which cooperatively carry a spring-loaded
pivotal latch member 58, and the latch member 58 itself. As is seen
best in FIG. 2, when the latch member 58 is moved aside (i.e.,
outwardly) at its forward end 58a by a user of the paint ball gun
10 pressing inwardly on a rear portion 58b of this latch member
(indicated by the arrow on FIG. 2), the latching bar 50 is able to
pivot outwardly and upwardly of pocket 52, viewing FIG. 2. As is
also seen in FIG. 2, pivoting of the latching bar 50 out of pocket
52 has the effect of pivoting the member or portion 42 (and barrel
20) about pin 44 to the second position seen in this drawing
Figure.
[0044] When the barrel 20 is pivoted to the position seen in FIG.
2, the breach opening 22a of this barrel is exposed and made
accessible so that a cleaning swab or brush on a cleaning rod may
be run thorough the barrel. Also, the breach area (i.e., breach
chamber 40, for example) of the paint ball gun 10 is made open and
accessible to be cleaned of paint and paint ball debris resulting
from breaking of a paint ball in the gun 10. Once the operator of
the paintball gun 10 is finished cleaning the barrel 20 and breach
area 40, the gun 10 may be put back into operation simply by
pivoting the portion or member 42 back to its position seen in FIG.
1. Thus, the latching bar 50 will be received and locked into
pocket 52 by the latching member 58.
[0045] Importantly, as is seen in FIG. 3, the member or portion 42
defines a bore 42a which defines the forward portion of bore 32,
defines the barrel-receiving portion 12a for the main frame 12, and
also defines a standard female barrel-receiving thread 52b allowing
a user of the paint ball gun to change barrels 20 when desired in
order to utilize a barrel better fitting a particular lot of paint
balls.
A Second Embodiment
[0046] Referring now to drawing FIGS. 4-6 in conjunction with one
another a second embodiment of a paint ball gun according to this
invention is illustrated. Because the embodiment of FIGS. 1-3, and
of FIGS. 4-6 have many features in common with, or features which
are analogous in structure or function, these features are
referenced in FIGS. 4-6 using the same numeral used above, but
increased by one-hundred (100). First considering FIG. 4, it is
seen that the paint ball gun 110 includes a main body 112, with a
grip frame 114 pivotally carrying a trigger 116 and defining a
trigger guard 118. A barrel 120 is threadably attached to the main
body 112, and defines a breech end opening (indicated by the arrow
122a) at which a paint ball may be received into the barrel 120. At
a muzzle end opening 122b, the paint ball may be discharged from
the barrel 120. A gas inlet regulator body 124 depends from the
main body 112 and communicates via an inlet 124a (arrowed on FIG.
4) with a source of high pressure gas. The paint ball gun 110 also
defines an upper feed tube 126 with an opening or feed port 128 for
receiving a supply of paint balls, indicated by arrowed numeral
130.
[0047] The feed port 128 opens into a top one 132 of two
substantially parallel and vertically spaced bores 132 and 134
defined by the main body 112. The barrel 120 is threadably received
at a rear portion 120c into the front of bore 132, at which the
main body 112 defines a barrel-receiving portion 112a. The barrel
120 is able to receive and discharge paint balls, as described
above.
[0048] A bolt assembly 138 with a handle portion 138a is
reciprocally and sealingly received into the rear portion of bore
132, and cooperates with the feed port 128 and with the barrel 120
at breech opening 122a to define a breech chamber 140 in which a
paint ball is sealingly received via feed port 128. Discharge of
the paint ball is indicated on FIG. 4 by the arrow exiting muzzle
122b.
[0049] A front part of the bore portion 134 communicates with the
accumulator 136, and when a user of the paint ball gun 110 pulls
the trigger 116, the pressurized gas communicated to the breach
chamber 140 and discharges a paint ball via barrel 120.
[0050] Considering now drawing FIGS. 4-6, it is seen that in order
to allow the barrel 120 to be moved aside to allow quick cleaning
of this barrel and the breach area 140 of the paint ball gun 110,
the front part of main body 112 includes a member or portion 142,
which is pivotally or hingeably mounted relative to the remainder
of the main body 112 via a vertically extending pin 144 carried by
the main body portion 112, and pivotally received in a boss 146
protruding on the right-hand side of the main body 112 (best seen
in FIG. 6). It will be understood that the invention is not limited
to the pivot axis defined by pin 144 being oriented vertically, and
that the embodiment of FIGS. 4-6 is an example only of a preferred
exemplary embodiment of the invention. For example, the pivot axis
for the member 142 may be oriented at any desired angle, such that
the barrel 120 is pivoted aside when moved to its second location.
Continuing with a consideration of the drawing Figures, it is seen
that this portion 142 is pivotally or hingeably movable between a
first position, seen in FIG. 4, and a second position seen in FIG.
6. The portion 142 defines a forward portion of bore 132, defines
barrel-receiving portion 112a, and carries the barrel 120. In its
first position, the portion 142 and the barrel 120 are aligned with
breach chamber 140 defined by a forward portion of bore 132 defined
within the remainder of main body 112. In this first position of
the portion 142, a seal is established between the rear face 142a
of the portion 142, and the forward face 112b of the main body 112.
Most preferably, a sealing member 148 (best seen in FIG. 6) will be
disposed at the surfaces defined by faces 142a and 112b in order to
provide a seal between these faces. In the embodiment seen in FIGS.
4-6, the seal member 148 is disposed in a groove 148a
circumscribing the breach chamber 140 at the rear opening of the
portion of bore 132 defined within the member or portion 142, as is
seen in FIG. 6.
[0051] In order to retain the portion 142 in its first position
seen in FIG. 4, while allowing it to be pivoted at will to the
second position seen in FIG. 6, this portion 142 pivotally carries
a spring-loaded latching member or pawl 150 protruding rearwardly
along the side of portion 142 opposite to boss 146. This latching
member 150 is arranged to engage with a latching boss 152 defined
along the left side of the main body 112 (as is best seen in FIG.
6)
[0052] As is seen best in FIG. 6, when the latch member 150 is
moved by an operator of the paint ball gun 110 upwardly against its
spring load this latch member disengages from the latching boss
152, allowing pivoting of the member or portion 142 about pin 144
to the second position seen in drawing FIG. 6. Again, when the
barrel 120 is pivoted to the position seen in FIG. 6, the breach
opening 120a of this barrel is exposed and made accessible so that
both the barrel 120 and the breach area (i.e., breach chamber 140,
for example) of the paint ball gun 110 is made open and accessible
to be cleaned of paint and paint ball debris resulting from
breaking of a paint ball in the gun 110. As with the first
embodiment disclosed and discussed above, once the operator of the
paintball gun 110 is finished cleaning the barrel 120 and breach
area 140, the gun 110 may be put back into operation simply by
pivoting the portion or member 142 back to its first position,
which in this embodiment is seen in FIG. 4. The latching member 150
will re-engage with the latching boss 152, and will retain the
barrel 120 in its first position.
[0053] Also, as is seen in FIG. 5, the member 142 defines a bore
142a (a forward portion of bore 132) which defines a standard
thread 152b allowing a user of the paint ball gun 110 to change
barrels 120 when desired in order to utilize a barrel better
fitting a particular lot of paint balls.
A Third Embodiment
Retrofit to a Conventional Paint Ball Gun
[0054] Referring now to drawing FIGS. 7-9 a third embodiment of a
paint ball gun according to this invention is illustrated. As will
be seen, this third embodiment includes a standard paint ball gun
210 (i.e., one not providing for removal of the barrel other than
by time-consuming unthreading of this barrel from the main body of
the paint ball gun). This embodiment also will be seen to include a
kit of parts (perhaps best seen in FIG. 9), which will be further
explained, and allowing and effecting conversion of the standard
paint ball gun to enjoy the advantages of this invention. Because
the embodiment of FIGS. 7-9 has many features in common with, or
features which are analogous in structure or function, to features
depicted and described above, these features are referenced in
FIGS. 7-9 using the same numeral used immediately above, but
increased by two-hundred (200) over their first use. First
considering FIG. 7, it is seen that a paint ball gun 210 includes a
main body 212, with a grip frame 214 pivotally carrying a trigger
216 and defining a trigger guard 218. A barrel 220 is threadably
attached to the main body 212 (via the retrofit kit--as will be
further explained), and defines a breech end opening (indicated by
the arrow 222a--best seen in FIG. 8) at which a paint ball may be
received into the barrel 220 for discharge therefrom. At a muzzle
end opening 222b, the paint ball will be discharged from the barrel
220.
[0055] As is seen best in FIG. 8, the barrel 220 is threadably
received at a rear portion 220c thereof into a threaded bore 242a
of a member 242. As is seen in FIG. 7, in a first position of the
member 242, this member and the barrel 220 align with the front of
bore 232, at which the main body 212 of the conventional paint ball
gun 210 defines a conventional barrel thread (not seen in the
drawing Figures). However, in this case, the barrel thread of the
paint ball gun main body 212 does not directly receive a barrel,
but receives a tubular adapter part 60 of the retrofit kit, which
is best seen in FIGS. 8a and 9. This tubular adapter part 60 at an
aft end portion thereof has an extension 62 and an external thread
64, which replicate the aft end of the paint ball gun barrel 220,
as is seen in FIG. 8. So, this adapter part 60 threadably engages
into the barrel thread at the front of the conventional paint ball
gun body 212, as is seen in FIGS. 7 and 8. The adapter part 60 at
its forward portion includes a flange portion 66 of enlarged
diameter, so that it provides a shoulder (indicated by arrowed
numeral 68 on FIGS. 8a and 9). The flange portion 66 defines
wrenching flats 70, and a bluff surface 72 upon which a bore 74
extending through the adapter part 60 opens.
[0056] About the adapter part 60 is carried a collar member 76
which may be annular or generally of C-shape, as is best seen in
FIG. 8a. On one side this collar member 76 defines an outwardly
extending boss 246 which in this embodiment (as is seen in FIGS. 7,
8, 8a, and 9), protrudes on the right-hand side of the main body
212. On the opposite side, the collar member 76 defines a latching
boss 252. At the boss 246, a portion 242 is pivotally or hingeably
received, and serves the same function as the portion 142 seen in
the embodiment of FIGS. 4-6. That is, the portion 242 threadably
receives the barrel 220 (refer to FIG. 8), and may be pivotally or
hingeably movable between a first position, seen in FIG. 7, and a
second position seen in FIG. 9. The portion 242 carries a
spring-loaded latching member 250 which engages with the latching
boss 252, as is best seen in FIGS. 7 and 8.
[0057] In order to secure the collar member 76 non-rotationally in
place on the main body of the paint ball gun 210, the user of the
gun removes the barrel 220, and threads adapter part 60 into place,
trapping the collar member 76. When the adapter part 60 is nearly
fully threaded into the barrel thread at the front of the main body
212, the user selects the rotational position for collar member 76
which is desired (i.e., selecting the pivot angle orientation for
the barrel 220 as it swings aside to the position seen in FIG. 9)
and securely tightens the adapter part 60 by application of torque
via wrenching flats 70. When the portion 242 is swung to its first
position seen in FIGS. 7 and 8, the seal member 248 carried in this
portion sealingly engages against bluff surface 72, and the latch
member 250 engages with latching boss 252. Operation of this
retrofitted paint ball gun, and movement of the barrel 220 to its
second position to allow barrel and breach cleaning is the same as
for the embodiment described with reference to FIGS. 4-6.
A Fourth Embodiment
Another Retrofit to a Conventional Paint Ball Gun
[0058] Referring now to drawing FIGS. 10-14 a fourth embodiment of
a paint ball gun according to this invention is illustrated. Again,
this fourth embodiment includes a standard paint ball gun 310
(i.e., one not providing for removal of the barrel other than by
time-consuming unthreading of this barrel from the main body of the
paint ball gun). In contrast to the retrofit embodiment seen in
FIGS. 7-9 (which provided a retrofitted gun similar in function to
the embodiment of FIGS. 4-6), however, the embodiment of FIGS.
10-14 provides a retrofitted paint ball gun with the barrel
pivoting aside similarly to the embodiment of FIGS. 1-3. This
embodiment of FIGS. 10-14 will also be seen to include a kit of
retrofit parts (perhaps best seen in FIGS. 13 and 14), which will
be further explained. The addition of the retrofit kit of parts to
a conventional paint ball gun allows and effects conversion of the
standard paint ball gun to enjoy the advantages of this
invention.
[0059] Because the embodiment of FIGS. 10-14 has many features in
common with, or features which are analogous in structure or
function, to features depicted and described above, these features
are referenced in FIGS. 10-14 using the same numeral used
immediately above, but increased by three-hundred (300) over their
first use. First considering FIG. 10, it is seen that a paint ball
gun 310 includes a main body 312, with a grip frame 314 pivotally
carrying a trigger 316 and defining a trigger guard 318. A barrel
320 is threadably attached to the main body 312 (via the retrofit
kit), and defines a breech end opening (indicated by the arrow
322a-best seen in FIG. 11) at which a paint ball may be received
into the barrel 320 for discharge therefrom. At a muzzle end
opening 322b, the paint ball may be discharged from the barrel
320.
[0060] As is seen best in FIG. 11, the barrel 320 is threadably
received at a rear portion 320c thereof into a threaded bore 342a
of a member or portion 342. As is seen in FIGS. 10 and 11, in a
first position of the member 342, this member and the barrel 320
align with the front of bore 332 (best seen in FIG. 13), at which
the main body 312 of the conventional paint ball gun 310 defines a
conventional barrel-receiving portion 312a (only a part of which is
seen in FIG. 13). However, in this case, the barrel thread of the
paint ball gun main body 312 does not directly receive a barrel,
but receives a tubular adapter part 160, which is best seen in FIG.
13. This tubular adapter part 160 at an aft end portion thereof has
an extension 162 and an external thread 164, which replicate the
aft end of the paint ball gun barrel 320, as is seen in FIG. 11.
So, this adapter part 160 threadably engages into the barrel thread
at the front of the conventional paint ball gun body 312, as is
seen in FIGS. 12 and 13. The adapter part 160 at its forward
portion includes a flange portion 166 of enlarged diameter, so that
it provides a shoulder 168. The flange portion 166 defines
wrenching flats 170, and a bluff surface 172 upon which a bore 174
extending through the adapter part 160 opens. About the adapter
part 160 is rotationally carried a generally C-shaped collar member
176 which on one side outwardly defines a boss 346 which (as is
best seen in FIGS. 12 and 13), protrudes on the right-hand side of
the main body 312.
[0061] A forwardly extending pin 344 is carried by the main body
portion 312 via collar member 176, and this pin is pivotally
received in a protruding boss 346 of the pivoting portion 342.
Thus, this pivoting portion 342 is pivotally or hingeably movable
between a first position, seen in FIGS. 10 and 11, and a second
position seen in FIGS. 12 and 13. The pivoting portion 342 defines
a forward portion of bore 332, defines barrel-receiving portion
312a, and threadably receives the adapter part 160 at portion 162
thereof. In its first position, the pivoting portion 342 and the
barrel 320 are aligned with breach chamber 340, which is defined by
a rearward portion of bore 332 defined within the remainder of main
body 312. In this first position of the portion 342, a seal is
established between the rear face 342a of the portion 342, and the
forward face 172 of the adapter member 160. Most preferably, a
sealing member of O-ring configuration, for example, will be
disposed at the surfaces defined by the faces 342a and 172 in order
to provide a seal between these faces.
[0062] On the opposite side (i.e., along the left-hand side of the
paint ball gun 310), the collar member 176 defines a latching boss
352. At the boss 346, a protruding spring-loaded detent member 346a
is received, and serves a latching function when the barrel is in
its first position seen in FIGS. 10 and 11. In this embodiment, the
user of the paint ball gun 310 has simply to apply a sufficient
pivoting force (indicated on FIG. 12 by the arcuate arrow) so as to
overcome the detenting force supplied by the member 346a. When the
user applies a sufficient pivoting torque, the barrel 320 and
member 342 will pivot aside to the position seen in FIGS. 12 and
13. After the barrel and breach are cleaned, the user of the gun
310 simply swings the barrel and portion 342 back to the position
seen in FIGS. 10 and 11, at which the detent member 346a will snap
into boss 352. Operation of this retrofitted paint ball gun is the
same as for the embodiment described with reference to FIGS.
1-3.
A Fifth Embodiment
Yet Another Retrofit to a Conventional Paint Ball Gun
[0063] Referring now to drawing FIGS. 15-17 a fifth embodiment of a
paint ball gun according to this invention is illustrated. As will
be seen, this fifth embodiment, like the third and fourth
embodiments, allows conversion of a standard or conventional paint
ball gun (i.e., one not providing for removal of the barrel other
than by time-consuming unthreading of his barrel from the main body
of the paint ball gun) to the advantages of this present invention.
Because the third and fourth embodiments illustrated the standard
or conventional paint ball gun, this fifth embodiment is
illustrated in isolation for economy of illustration.
[0064] This fifth embodiment also will be seen to include a kit of
parts allowing and effecting conversion of the conventional or
standard paint ball gun to enjoy the advantages of this invention
because as so retrofitted, the barrel of the standard paint ball
gun can be quickly removed for cleaning and just as quickly can be
replaced to put the gun back into operation. This quick clearing of
the paint ball gun and its return to operation is very important to
a competitive paint ball player.
[0065] First considering FIG. 15, it is seen that a quick-release
barrel mount 78 for mounting to a conventional or standard paint
ball gun (not seen in FIGS. 15-17) includes a first portion 80
which at an aft end part 82 thereof replicates the configuration of
the aft end of a standard paint ball gun barrel (recalling FIGS. 11
and 14, for example. This first portion 80 is much the same as part
160 seen in FIG. 13, and threads into the body of the paint ball
gun in place of the barrel. The first portion 80 captures thereon
and holds in place a generally ring-shaped second part 84 which
includes a pair of diametrically-opposed and radially outwardly
extending lugs 86 (only one of which is seen in the drawing
Figures). These lugs 86 are engaged by a matching pair of
hook-shaped arms 88 protruding rearwardly from a barrel mount
member 90. As is seen best in FIGS. 15 and 17, the second part 84
also defines an elongate boss 92 carrying a spring-loaded detent
member 92a (best seen in FIG. 17). This detent member 92a engages
in a first relative position of the members 84 and 90 (as is seen
in FIG. 15) into a shallow detent pocket (not seen in the drawing
Figures) defined at the aft face of a detent tab 94 extending
radially outwardly on the member 90. At a forward end opening of
the member 90, a through bore 96 opens, and defines a
barrel-receiving thread 96a.
[0066] A user of the quick-release barrel mount seen in FIGS. 15-17
first attaches the member 84 to the main body of a paint ball gun
using the first portion 80, as was explained above about use of the
part 160 seen in FIG. 13. The part 84 defines a bluff surface
against which a seal member (not seen in the drawing Figures)
carried on member 90 sealing engages in the first relative position
of these parts. Then the user of the paint ball gun threadably
attaches the member 90 at the aft end of a selected paint ball gun
barrel, and attaches the members 84 and 90 together as seen in FIG.
15 by a combination of axial and rotational motion, indicated by
the cranked arrow on FIG. 15. This motion engages the arms 88 with
the lugs 86, and results in the detent member 92a engaging the
detent lug 94. As so mounted, the paint ball gun is operational and
will shoot paint balls.
[0067] As FIGS. 16 and 17 illustrate, in the event the user of the
paint ball gun desires to quickly remove the barrel from the paint
ball gun (i.e., for cleaning of the barrel and/or breach area of
the gun) then a partial turn of the barrel (FIG. 16) of less than
180 degrees, will unlatch the detent 92a from detent tab 94. This
rotational movement is followed by an axial movement along the axis
of the barrel (FIG. 17) which will remove the barrel from the gun
for cleaning. Of course, removing the barrel from the gun, also
exposes the breach area of the gun for cleaning. Replacement of the
barrel onto the paint ball gun is the opposite to removal, and is
equally quick. As a result, the paintball gun can be cleaned and
quickly be placed back into operation even during a competition or
paint ball game.
A Sixth Embodiment
[0068] Referring now to drawing FIGS. 18 and 19, a sixth embodiment
of a paint ball gun according to this invention is illustrated.
This sixth embodiment also has many features in common with, or
features which are analogous in structure or function, to those
depicted and described above. These features are referenced in
FIGS. 18 and 19 using the same numeral used above, but increased by
four-hundred (400) over their first appearance. Considering FIG.
18, it is seen that the paint ball gun 410 includes a main body
412, with a grip frame 414 pivotally carrying a trigger 416 and
defining a trigger guard 418. A barrel 420 may be threadably
attached to the main body 412 (as will be further explained). This
barrel 420 defines a breech end opening (indicated by the arrow
422a) at which a paint ball may be received into the barrel 420 for
forceful discharge. The paint ball gun 410 also defines an upper
feed tube 426 with an opening or feed port 428 for receiving a
supply of paint balls, as will be well understood.
[0069] The feed port 428 opens into a top one 432 of two
substantially parallel and vertically spaced bores 432 and 434
defined by the main body 412. The barrel 420 is threadably
receivable at a rear portion 420c into the front of bore 432, at
which the main body 412 defines a barrel-receiving portion 412a.
The barrel 420 is able to receive and discharge paint balls, as
described above. A bolt assembly 438 with a handle portion 438a is
reciprocally and sealingly received into the rear portion of bore
432.
[0070] Considering now drawing FIGS. 18 and 19 in greater detail,
it is seen that in order to allow the barrel 420 to be quickly
attached to and removed from the main body 412, the body defines a
screw thread 412a which in this embodiment is circumferentially
interrupted. That is, the screw thread 412a defines one or more
axially extending "grooves" at which the screw thread 412a is
interrupted. Similarly, viewing FIG. 19, the barrel 420 at screw
thread portion 420c is circumferentially interrupted, and defines
one or more matching axially extending grooves at which the screw
thread 420c is interrupted. It will appear that the screw thread
sections at 420c on barrel 420 are receivable axially into the
grooves defined by screw thread 412a of the body 412. Thus, as is
seen in FIG. 18, a user of the gun 410 may mount the barrel 420 to
the body 412 by first inserting the portion 420c axially into the
bore part 412a, with the thread parts of each passing along the
grooves of the other, and then rotating the barrel 420 a part turn
to lock the barrel in place. This axial-followed-by-rotational
movement is represented on FIG. 18 by the cranked arrows adjacent
to barrel 420, indicating the first axial motion, followed by the
rotational motion. The barrel 420 is removed from main body 412 by
opposite motions.
[0071] In view of the above, it will be seen that main body 412 may
employ conventional or standard paint ball gun barrels, which
simply thread into place conventionally. Similarly, the barrel 420
may be employed on a conventional or standard paint ball gun, and
will simply thread into place conventionally. However, when main
body 412 and barrel 420 are used together, then the barrel 420 may
be quickly installed on and removed from the main body 412 by a
combination of axial and rotational motions as described above. As
before, when the barrel 420 is removed form the main body 412, the
barrel and breach area of the gun 410 are available for
cleaning.
A Seventh Embodiment
[0072] Referring now to drawing FIGS. 20 and 21 in conjunction with
one another a seventh embodiment of a paint ball gun according to
this invention is illustrated. Because the embodiment of FIGS. 20
and 21 have many features in common with, or features which are
analogous in structure or function, to features illustrated and
described in prior embodiments of the invention, these features are
referenced in FIGS. 20 and 21 with the same numeral used above, but
increased by another increment of one-hundred (100) over the last
prior use.
[0073] First considering FIG. 20, it is seen that the paint ball
gun 510 includes a main body 512, with a grip frame 514 pivotally
carrying a trigger 516 and defining a trigger guard 518. A barrel
520 is threadably attached to the main body 512, and defines a
breech end opening (indicated by the arrow 522a) at which a paint
ball may be received into the barrel 520. At a muzzle end opening
(not seen in the drawing Figures) the paint ball may be discharged
from the barrel 520. A gas inlet regulator body 524 depends from
the main body 512. The paint ball gun 510 also defines an upper
feed tube 526 with an opening or feed port 528 for receiving a
supply of paint balls, indicated by arrowed numeral 530.
[0074] Considering now drawing FIGS. 20 and 21 in detail, it is
seen that in order to allow the barrel 520 to be moved from a first
or operative position allowing the gun 510 to be fired and to a
second or opened position allowing both the bore of the barrel 520
and the breach area of the main body 512 to be cleaned, the main
body 512 includes a portion 542, which at a forward end threadably
receives the barrel 520 (as is seen in FIG. 20). At its aft end,
the portion 542 includes a rearwardly extending tang 542a, which on
an underside thereof defines a female dovetail feature (indicated
by arrow 542b on FIG. 21). The main body 512 defines a matching
male dovetail feature 512a (best seen in FIG. 21) onto which the
female dovetail feature of the portion 542 is axially receivable,
as is indicated by the large movement arrow in FIG. 21. As is
indicated in FIGS. 20 and 21, the main body 512 carries a pair of
spring-loaded latching fingers 558a and 558b (best seen in FIG.
21). These latching fingers each engage a respective one of a pair
of latch protrusions 550a, 550b (only one of which is seen fully in
FIG. 21) in order to retain the portion 542 and barrel 520 is their
operative position, as is seen in FIG. 20. When the latching
fingers 558a and 558b are operated by a user of the paint ball gun
510, and the barrel 520 and portion 542 may slide forwardly along
and off of the dovetail 512a (i.e., leftwardly viewing the drawing
Figures, as is indicated by the double-headed movement arrow in
FIG. 21). Then the breach end of barrel 520 and the breach area of
the main body 512 are exposed for cleaning. Restoration of the
barrel and portion 542 onto the gun 510 to return the gun to
operation is illustrated in FIG. 21 by the right-ward direction of
the double-headed motion arrow.
An Eighth Embodiment
[0075] Referring now to drawing FIGS. 22 and 23 in conjunction with
one another yet another embodiment (i.e., an eight embodiment) of a
paint ball gun according to this invention is illustrated. Again,
because the embodiment of FIGS. 22 and 23 have many features in
common with, or features which are analogous in structure or
function to, features illustrated and described in prior
embodiments of the invention, these features are referenced in
FIGS. 22 and 23 with the same numeral used above, but increased by
another increment of one-hundred (100) over the last prior use.
[0076] First considering FIG. 22, it is seen that the paint ball
gun 610 includes a main body 612. A barrel 620 is threadably
attached to the main body 612, and defines a breech end opening
(indicated by the arrow 622a) at which a paint ball may be received
into the barrel 620. At a muzzle end opening (not seen in the
drawing Figures) the paint ball may be discharged from the barrel
620. Considering drawing FIGS. 22 and 23 in comparison to one
another, it is seen that in order to allow the barrel 620 to be
moved from an operative position allowing the gun 610 to be fired
and to an opened position allowing both the bore of the barrel 620
and the breach area of the main body 612 to be cleaned, the main
body 612 includes a portion 642, which at a forward end threadably
receives the barrel 620 (as is seen in FIG. 22).
[0077] At its aft end, the portion 642 includes a pair of
rearwardly extending tangs 642a, 642b (only one of which is fully
seen in FIG. 23). These tangs 642a/b are vertically spaced apart,
and cooperatively define a laterally-extending female dove tail
groove, indicated on FIG. 23 with the numeral 642c. The main body
612 defines a matching vertically spaced apart and
laterally-extending male dovetail feature 612a, 612b (best seen in
FIG. 23) onto which the female dovetail feature 642c of the portion
642 is axially receivable, as is indicated by the double-headed
motion arrow seen in FIG. 23. When the portion 642 is received onto
the dovetail feature 612a, 612b, as is seen in FIG. 22, the gun 610
is operational and may be fired. Conversely, when an operator of
the gun 610 slides the barrel 620 and portion 642 laterally to the
relative position seen in FIG. 23, then the bore of the barrel 620
and the breach area of the main body 612 are exposed for
cleaning.
[0078] As is best seen in FIG. 23, the main body 612 defines a
detent recess 646, which will be engaged by a protruding detent
member (not seen in the drawing Figures) carried at the aft face of
portion 642 when the barrel 620, portion 642, and main body are in
their relative position seen in FIG. 22, so that the gun 610 is
operational to fire a paint ball. To move the portion 642 and
barrel 620 between the positions seen in FIGS. 22 and 23, the user
of the paint ball gun 610 simply applies a sufficient lateral force
to overcome the detent force provided at recess 646, and the
portion 642 will slide laterally on or off of the dovetail features
described above.
[0079] While the invention has been described in connection with
what is presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention is not to be
limited to the disclosed embodiments but is intended to be limited
only by the spirit and scope of the appended claims, giving full
cognizance to equivalents, and to various modifications and
improvements as is permitted under the law. For example, it is
apparent that the embodiment of FIG. 18 could employ another
version of an interrupted thread type of engagement. However,
considering the disclosure set out above, it is apparent that this
invention provides a paint ball gun in which the breach end of the
barrel, and the breach of the gun mechanism, may both be quickly
accessed for cleaning with a movement of the barrel through less
then 360 degrees. In most of the present embodiments, the barrel
and gun breach are accessible with a movement of 90 degrees or
less.
