BACKGROUND OF THE INVENTION
[0004] This invention relates generally to barrel assemblies for
non-lethal personal defense devices, and more specifically to
launchers that deliver non-lethal chemicals to an animal or human
target using projectiles containing said chemicals. The launchers
include, but not limited to, pressurized-gas powered devices, such
as a regular paintball marker or paintball gun. The projectiles can
be paintball-sized balls containing pepper spray liquid, pepper
powder, pepper gel and other chemicals.
[0005] The most commonly used non-lethal personal defense devices
include pepper sprayers, pepper-ball launchers and stun guns.
However, these current devices have their own shortcomings that
severely limit their applications.
[0006] U.S. Patent Application Publication 20020176254A1 to Kostal
et al. reported a compact pepper sprayer, which combines a regular
pepper sprayer with a flashlight. U.S. Pat. Nos. 6,546,661 and
6,196,419 to Staubs and Haney et al., respectively, disclosed two
similar gun-mounted sprayers. Both of them are actually regular
sprayers mounted on a mechanism operated similar to a regular
handgun--using the trigger of the gun to activate the sprayer. All
of the above compact sprayers are limited in applications by the
short distance that the spray can cover and by the slow speed that
the spray is delivered to the target, even though these sprayers
are compact, effective under the right circumstances and truly
non-lethal to the living target.
[0007] U.S. Patent Application Publications 20040020946A1 (by
Fleischhauer), 20030056638A1 (by Poole) and 20030034404A1 (by
Truelove) discussed potentially much larger sprayer systems than
the compact sprayers. These large sprayers work similarly to the
compact sprayer in principal by directly delivering the non-lethal
pressurized chemical agents to the target in a form of spray.
Although their sprays can cover much longer distance, the large
sprayer systems are slow in speed and not convenient to use due to
their large sizes.
[0008] U.S. Patent Application Publication 20030047105A1 by Vasel
et al. discussed a non-lethal projectile for non-lethally
inhibiting a living target using multi-functional launching
devices. It also discussed methods of the use of such non-lethal
projectile: by using launchers that work in the same way as a
paintball marker or paintball gun, the projectile is delivered to
the target and the projectile body ruptures upon impact on the
target, releasing the chemical substance inside of the projectile.
Using this method, the chemicals can be delivered to a target much
farther away and at much quicker speed than using a regular
sprayer. However, the projectile needs to directly hit certain
areas on the living target to be effective, causing unacceptable
uncertainties in aiming, especially at moving targets. Further
more, some projectiles fail to rupture after impact, very similar
to regular paintballs used in the sport shooting game.
[0009] PCT Publication WO 200407336A2 by Nerheim of Taser
International Inc. reported the latest development about Taser stun
guns--a device used for disabling living target by providing an
electric current through electrodes and the target in a circuit
having an air gap between an electrodes and the target. The
50,000-volt current passed between the two electrodes is believed,
by some, to be the cause of some deaths amongst the people who have
been hit by a Taser stun gun. The real causes of those deaths are
being disputed by various parties involved, but there is one thing
for certain--the high voltage current definitely makes the Taser
stun gun more lethal than the pepper-spray-based devices.
[0010] In summary, most commonly used non-lethal personal defense
devices are limited in applications by their own shortcomings and
remain a source of frustration for users and law enforcement
agents. A cost-effective, compact, swift, effective and
truly-non-lethal personal defense device can certainly help promote
homeland security in the United States and is much needed by the
public.
BRIEF SUMMARY OF THE INVENTION
[0011] The present invention addresses the aforementioned problems
by providing a barrel assembly for delivering non-lethal
projectile, such as a pepper ball, to a living target, using
various personal defense launching devices, such as compressed
CO.sub.2-powered paintball gun and other compressed-gas-powered
launchers. More specifically, the barrel assembly has metal pins
inside its bore. The said pins are located near the exit of said
barrel assembly and are in the path of the projectile in order to
pinch and rupture the non-lethal projectile after the projectile
has been accelerated inside the barrel. The prototype barrel
assembly used with a CO.sub.2-powered paintball gun has shown that
the method can effectively break, spread and disperse the content
of a non-lethal projectile, that the substance inside the
projectile can reach a target much farther away and at a much
faster speed than a regular spray. Since the projectile is ruptured
at the exit of the barrel, the chemical substance in the projectile
is widely dispersed before reaching the target and covers a large
area that is similar to a regular pepper spray, effectively forming
a bullet pepper spray. Such a pepper spray, scientifically named as
oleoresin capsicum, can temporarily incapacitate the living target
instantly. As a result, precise aiming at the target is not
required and only "point-and-shoot" is needed. A barrel assembly
disclosed in the present invention used in a CO.sub.2-powered
paintball handgun, such as the ones disclosed in U.S. Patents
Application Publications 20030047174A1 and 20030106545A1 to
Tiberius et al. and Verini, respectively, firing a pepper ball,
such as the ones disclosed by U.S. Patent Application Publication
20030047105A1 by Vasel et al, is well qualified as a
cost-effective, compact, swift, effective and truly-non-lethal
personal defense device.
[0012] Variations of the barrel assembly include using non-metal
pins, blades, gear-teeth, orifice or reduced inner diameter of the
barrel at the exit, near the exit or in the middle of the
barrel.
[0013] A variation of the use of the barrel assembly is to launch
more than one non-lethal projectile during one launch to increase
the delivery dosage and the covering area by the chemical substance
released from the projectile. Two as well as three paintballs have
been successfully launched by the prototype barrel assembly during
one launch with a CO.sub.2-powered paintball gun and showed
significant increase in the area on the target covered by the
paint.
[0014] The pressurized-gas-powered launcher can be a pistol
(disclosed in U.S. Patents Application Publications 20030047174A1
and 20030106545A1 to Tiberius et al. and Verini, respectively), a
rifle (such as those disclosed in U.S. Pat. No. 5,950,611 to Lopez
et al., U.S. Patents Application Publications 20040134476A1 by
Smith et al and 200301315A1 by Rice et al) and other alternative
types (U.S. Patent Application Publication 20030047105A1 by Vasel
et al).
[0015] Further aspects of this invention will become apparent in
the Detailed Description and by reference to the attached
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0024] In the following description, reference is made to the
accompanying drawings, which form a part hereof, and which show, by
way of illustration, specific embodiments or processes in which the
invention may be practiced. Where possible, the same reference
numbers are used throughout the drawings to refer to the same or
like components. In some instances, numerous specific details are
set forth in order to provide a thorough understanding of the
present invention. The present invention, however, may be practiced
without the specific details or with certain alternative equivalent
devices and methods to those described herein. In other instances,
well-known methods and devices have not been described in detail so
as not to unnecessarily obscure aspects of the present
invention.
[0025] FIGS. 1A, 1B and 1C show a CO.sub.2-powered paintball pistol
1, similar to the one disclosed in U.S. Patents Application
Publications 20030047174A1 to Tiberius et al., installed with a
preferred embodiment of the present invention including barrel 7
and metal pins 22, 23, 24 and 25 at the exit of barrel 7. Pistol 1
is mainly consisted of CO.sub.2 cylinder 2, handle 3, pepper-ball
loader 4, pepper ball 5 and trigger 6. Pepper ball 5 can be made
using the methods disclosed by Vasel et al. in U.S. Patent
Application Publication 20030047105A1. Trigger 6, when pressed,
releases a portion of the compressed gas in cylinder 2. The gas
pushes pepper ball 5 in barrel 7 towards the exit. Pepper ball 5 is
swiftly accelerated to a very high speed (at least 100 meters per
second) before reaching metal pins 22 through 25. Although a
minimum of three (3) pins are needed to pinch the ball and to
achieve the desired results, a single pin can still rupture the
ball. Therefore, the number of pins used could vary. There are
different ways to insert the pins into the barrel. The easiest way
is to tap threads in the barrel and screw the pins in, as shown in
FIG. 1A.
[0026] As pepper ball 5 passes through pins 22 through 25, it is
ruptured and the liquid pepper substance inside is dispersed by the
high pressure gas behind and by the air resistance ahead, as shown
in FIG. 4. FIG. 4 shows a partial view of barrel 7, in which pepper
ball 5 is about to be ruptured by pins 22 and 23 during a launch.
The ruptured pepper ball 26, with its pepper substance traveling at
100 meters per second, is quickly spread into spray 27. Spray 27 is
further dispersed into an even larger spray or plume 28 completing
the formation of bullet spray 29 before reaching human target
30.
[0027] FIG. 2 discloses barrel assembly 8 according to the
embodiment of a variation of the present invention. Barrel assembly
8 is consisted of barrel 7 and barrel cap 10. Barrel cap 10 is
screwed to barrel 7 via threads 13 and sealed by o-ring 9. Barrel
cap 10 has the same or slightly bigger inner diameter than barrel
7. Similar to the pistol shown in FIG. 1A, pistol 1 is consisted of
CO.sub.2 cylinder 2, handle 3, pepper-ball loader 4, pepper ball 5
and trigger 6. Trigger 6 releases a portion of the compressed gas
in cylinder 2. The gas accelerates pepper ball 5 in barrel 7
towards exit 12. Orifice 11 is near the exit and has a smaller
diameter than the inner diameter of barrel cap 10. Pepper ball 5 is
ruptured as it squeezes through orifice 11 at very high speed.
[0028] There are different ways to attach barrel cap 10 to barrel 7
as well as different ways to rupture pepper ball 5, resulting in
other variations of the barrel assembly. A metal mesh installed at
the barrel exit, outside of the barrel, for example, can not only
break the pepper ball but also trap the debris of the pepper ball
shells, preventing possible minor injuries to the living
target.
[0029] FIG. 3A discloses a variation of barrel assembly 8 according
to the embodiment of a variation of the present invention. Barrel
assembly 8 is consisted of barrel 7 and barrel cap 14. Barrel cap
14 is attached to barrel 7 via pins 15 and sealed by o-ring 16.
Barrel cap 14 has the same or slightly bigger inner diameter than
barrel 7. Similar to the pistol shown in FIG. 1A, pistol 1 is
consisted of CO.sub.2 cylinder 2, handle 3, pepper-ball loader 4,
pepper ball 5 and trigger 6. Trigger 6 releases a portion of the
compressed gas in cylinder 2. The gas accelerates pepper ball 5 in
barrel 7 towards exit 18. Pepper ball 5 is ruptured by gear-teeth
17, 19, 20 and 21, as shown in FIG. 3B.
[0030] While certain preferred embodiments have been described and
shown in the accompanying drawings, it is to be understood that
such embodiments are merely illustrative of, and not restrictive
on, the broad invention. Other embodiments that are apparent to
those of ordinary skill in the art, including embodiments that do
not provide all of the features and advantages set forth herein,
are also within the scope of this invention. Further, it is to be
understood that this invention is not limited to the specific
construction and arrangements shown and described since various
modifications or changes may occur to those of ordinary skill in
the art without departing from the spirit and scope of the
invention. Accordingly, the scope of the invention is defined by
the claims that follow. In the claims, a portion shall include
greater than none and up to the whole of a thing. In the method
claims, reference sequences are used for convenience of description
only, and do not indicate a particular order for performing the
method.
