Paintball gun
Abstract
A paintball gun is to directly shoot a paintball by using
pressurized air to avoid the fast movement of a hammer protruding
from a barrel from hurting the hand of a user. A low-pressure
regulator is turned to block a port of the barrel to prevent the
pressurized air from entering into the barrel to avoid hurting
people by accidentally pulling the trigger.

Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention relates to a paintball gun, and more
particularly, to one that applies pressurized air to directly fire
a paintball, having the pressurized air passing through a spool, an
opening and a through hole of a piston, and has a port blocked by
turning a low-pressure regulator to avoid hurting people by
accidentally pulling a trigger.
[0003] (b) Description of the Prior Art
[0004] Survival game in jungle is quite popular sport, and a use of
a paintball gun is the essence in the game. To mitigate the risks
of using the paintball gun, a flask filled with pressurized air is
essentially used as the motive power to shoot the paintball gun. As
illustrated in FIG. 5 of the accompanying drawings, the paintball
is fired by having provided a drop hole (A2) provided on the tip of
a barrel (A1) of a paintball gun (A) to permit a paintball (B) to
automatically drop into the barrel (A1). When a trigger (A3) is
pulled, a hammer (A4) linked to the trigger (A3) drives a bolt (A5)
to fire the paintball (B). A slot (A6) is provided at the terminal
of the barrel (A1) for a connecting pin (A7) disposed between the
hammer (A4) and the bolt (A5) to move and pass through. However,
the connecting pin (A7) moves very quickly at the moment the
paintball (B) is fired and the top of the connecting pin (A7)
sticks out of the barrel (A1); therefore the protruding end of the
connecting pin (A7) and the end of the bolt (A5) could easily hurt
the hand of the user. Furthermore, the entire firing installation
is not provided any protection from elements encountered adverse in
playing conditions. The paintball gun can be easily fired by
accidentally pulling the trigger to hurt people. Being exposed to
such risk, the shooting fun is often frustrated during the
game.
SUMMARY OF THE INVENTION
[0005] The primary purpose of the present invention is to provide a
paintball gun that applies pressurized air to directly fire the
paintball. To achieve the purpose, a T-valve is provided in a frame
of the paintball gun to control the passage of low-pressure air; a
spool is also provided in a barrel of the frame with an opening
disposed at its front end and a piston is inserted into the
opening; a spring is provided between the piston and the spool,
both the piston and the spool are each provided with a through hole
connecting to their respective outer edges; a through channel is
disposed at the terminal of the spool; and a low-pressure regulator
is provided in an air storage chamber and adapted with a block.
When the trigger is pulled, the T-valve admits the low-pressure air
to enter into the through channel to push the piston and to advance
the paintball while the pressurized air passes from the air storage
chamber in sequence through the port, the spool, the opening and
the through hole of the piston to fire the paintball. By having the
pressurized air to directly fire the paintball, there would be no
fast move by the hammer protruding out of the barrel, thus there is
not chance that the hand of the user to get hurt. When the
low-pressure regulator is turned to block the port, it stops the
pressurized air in the air storage chamber from entering into the
barrel, thus to prevent accidentally pulling the trigger to hurt
somebody.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Referring to FIGS. 1, and 2, the present invention
essentially comprises a frame (1), a spool (2), and a low-pressure
regulator (3). The frame (1) is provided with a barrel (11). A
paintball drop hole (12) is disposed at the top side of the barrel
(11). An air storage chamber (13) is adjacent to the barrel (11). A
port (14) and a keyhole (15) are respectively provided in the front
section and the rear section between the air storage chamber (13)
and the barrel (11). The front end of the air storage chamber (13)
is connecting through a pressurized air flask (16) so to input the
pressurized air into the air storage chamber (13). A trigger (17)
and a T-valve (18) are connected to the frame (1). The trigger (17)
controls the operation of the T-valve (18). The T-valve (18) is
disposed with an air inlet hole (181) connecting through an air
inlet way (182). Furthermore, an air outlet hole (183) is provided
in the T-valve (18) to connect through an air outlet way (184) for
allowing low-pressure air to pass through.
[0012] The spool (2) disposed in the terminal of the barrel (11)
has an opening (21) at the front edge of the spool (2). A piston
(22) is inserted into the opening (21) to block the opening (21) of
the spool (2). A spring (221) is disposed between the piston (22)
and the spool (2). Two through holes (23), (24) are respectively
provided to the spool (2) and the piston (22) to connect through
their respective outer edges. A through channel (25) is disposed at
the rear end of the spool (2) to connect through the lower-pressure
air transmitted by the air outlet way (184).
[0013] The low-pressure regulator (3) is turned to be disposed at
the terminal of the air storage chamber (13). The low-pressure
regulator (3) has on its circumference provided in recess a groove
(31), and its front end, a block (32).
[0014] When in use as illustrated in FIG. 2, the pressurized air
from the pressurized air flask (16) fills up the air storage
chamber (13) and enters into the spool (2) through the port (14).
Since the piston (22) plugs the opening (21) of the spool (2), the
pressurized air is accumulated inside the spool (2). Once a
paintball (B) falls from the paintball drop hole (12) into the
front edge of the barrel (11), the trigger (17) is pulled for the
T-valve (18) to start operating to admit the low-pressure air
passes through in sequence from the air inlet way (182) into the
air inlet hole (181) and outputted through the air outlet hole
(183) to pass through the air outlet way (184), the groove (31) of
the low-pressure regulator (3), as illustrated in FIG. 3, and
finally into the through channel (25) of the spool (2). The
low-pressure air then starts to push the piston (22) in the spool
(2) to move forward and compress the spring (221). As the piston
(22) advances, the paintball (B) is pushed to the battery position
while the piston (22) is cleared of the opening (21). The
pressurized air accumulated in the spool (2) is discharged at high
speed from the opening (21) and ejected from the through hole (24)
of the piston (22) to shoot the paintball (B) by the impetus from
the pressurized air. After having shot the paintball (B) by the
pressurized air, the piston (22) is pushed back to its original
position thanks to the return force executed by the spring (221) to
plug the opening (21) once again until the next shot.
[0015] To avoid pulling the trigger (17) by accident, the
low-pressure regulator (3) is turned, as illustrated in FIG. 4, for
the block (32) disposed at the front end of the low-pressure
regulator (3) to move inside the air storage chamber (13) thus to
plug the port (14) to stop the pressurized air in the air storage
chamber (13) from entering into the barrel (11) to shoot the
paintball (B) accidentally.
