Firing mechanism of airsoft gun
Abstract
A firing mechanism of an airsoft gun includes a canister of
propellant having an outlet member. The firing mechanism includes a
pivotal follower engaged with a trigger; and a valve assembly
including a spring biased sliding rod urging against the follower,
an O-ring put on the sliding rod for blocking the outlet member, a
well on the sliding rod, a chamber having an outlet element, a
passage interconnecting the outlet member and the chamber, and a
ball seated on the outlet element for blocking the chamber; a
channel in communication with the chamber; and a spring biased
stopper for closing a forward end of the channel. In response to
pulling the trigger, the pivotal follower rotates to move the
sliding member rearward so that propellant supplied by the canister
may push a projectile out of the airsoft gun.

Claims
1. A firing mechanism of an airsoft gun including a canister of
propellant having an outlet member, comprising: a trigger; a
pivotal follower operatively engaged with the trigger; and a valve
assembly including a spring biased sliding rod urging against the
pivotal follower, a main O-ring put on the sliding rod for blocking
the outlet member, a well formed on the sliding rod, a chamber
having an outlet element, a passage interconnecting the outlet
member and the chamber, and a ball seated on the outlet element for
blocking the chamber; a channel in communication with the chamber;
and a spring biased stopper for blocking a forward end of the
channel; wherein in response to pulling the trigger, the pivotal
follower rotates to move the sliding member rearward, move the main
O-ring out of the outlet member, and move the well rearward to
receive a portion of the ball to unblock the outlet element so that
propellant supplied by the canister of propellant is configured to

passage; the pressurized gas further flows out of the outlet
element into the channel; and the pressurized gas leaves the
channel by pushing the spring biased stopper forward.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to airsoft guns and more particularly
to a firing mechanism of an airsoft gun (e.g., air pistol) having
improved characteristics.
[0003] 2. Description of Related Art
[0004] There is a conventional projectile launcher comprising a
firing mechanism having a first portion and a second portion in
sealed, sliding engagement with each other and cooperating to
define an air chamber, the first portion configured to move to a
cocked position by a slide, a biasing member urging the first
portion away from the cocked position. The movement of the first
portion from the cocked position under the biasing force of the
biasing member reduces a volume of the air chamber to create a
burst of air capable of launching a projectile from the barrel. The
second portion includes a loading member that selectively blocks an
opening of a reservoir. The second portion moves with movement of
the slide toward the cocked position such that the loading member
unblocks the opening of the reservoir to permit a projectile to
move from the reservoir through the opening to the barrel.
[0005] While the device enjoys its success in the market,
continuing improvements in the exploitation of firing mechanism of
airsoft gun of this type are constantly sought.
SUMMARY OF THE INVENTION
[0006] It is therefore one object of the invention to provide a
firing mechanism of an airsoft gun including a canister of
propellant having an outlet member, comprising a trigger; a pivotal
follower operatively engaged with the trigger; and a valve assembly
including a spring biased sliding rod urging against the pivotal
follower, a main O-ring put on the sliding rod for blocking the
outlet member, a well formed on the sliding rod, a chamber adjacent
to the well, a passage interconnecting the outlet member and the
chamber, an outlet element on the chamber, and a ball seated on the
outlet element for blocking the chamber; a channel in communication
with the chamber; and a spring biased stopper for closing off a
forward end of the channel; wherein in response to pulling the
trigger, the pivotal follower rotates to move the sliding member
rearward, move the main O-ring out of the outlet member, and move
the well rearward to receive a portion of the ball to unblock the
outlet element so that propellant supplied by the canister of
propellant is configured to leave out of the outlet member to enter
the chamber via the passage; the pressurized gas further flows out
of the outlet element into the channel; and the pressurized gas
leaves the channel by pushing the spring biased stopper.
[0007] The above and other objects, features and advantages of the
invention will become apparent from the following detailed
description taken with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0015] Referring to FIGS. 1 to 7, an airsoft gun (e.g., air pistol)
in accordance with the invention comprises the following components
as discussed in detail below.
[0016] A body 1 has a barrel portion and a grip portion. A trigger
11 is adjacent to the grip portion. A pivotal follower 12 is
operatively engaged with the trigger 11. A canister 10 of
propellant (e.g., compressed gas) is provided in the grip portion.
An outlet member 13 is provided downstream of a flow path of the
compressed gas leaving the canister 10. A valve assembly 2 is
provided in a rear portion of the body 1 and includes a sliding rod
20 urged by a torsion spring 19 in the body 1 against the pivotal
follower 12, a main O-ring 21 put on a recess 22 of the sliding rod
20 for blocking the outlet member 13 when the trigger 11 is not
pulled, a half-spherical well 27 disposed rearward of the recess
22, a chamber 24 adjacent to the well 27, a passage 23
interconnecting the outlet member 13 and the chamber 24, an outlet
element 25 on the opening of the chamber 24, a ball 26 seated on
the outlet element 25 and proximate to an edge of the well 27, a
forward O-ring 28A put on the sliding rod 20, a rear O-ring 28B put
on the sliding rod 20, and a spring biased stopper 29 for closing
off a forward end of a channel 30 which communicates with the
chamber 24. An intermediate O-ring 18 is put on the sliding rod 20
between the main O-ring 21 and the well 27.
[0017] In response to pulling the trigger 11, the pivotal follower
12 clockwise rotates to move the sliding member 20 rearward with
the torsion spring 19 further compressed. And in turn, the main
O-ring 21 slightly clears out of the outlet member 13. Thus,
pressurized gas supplied by the air canister 10 leave the outlet
member 13 to enter the chamber 24 via the passage 23. Also, the
well 27 moves rearward to receive a portion of the ball 26 to
unblock the outlet element 25. Then the pressurized gas flows out
of the chamber 24 into the channel 30. And in turn, the pressurized
gas leaves the channel 30 by pushing the stopper 29 forward. And in
turn, the forward moving stopper 29 pushes a projectile (e.g.,
paintball) 3 into the barrel portion. Finally, the projectile 3 is
launched.
[0018] As shown in FIG. 7 specifically, after releasing the trigger
11, the trigger 11 rotates clockwise. And in turn, the pivotal
follower 12 rotates counterclockwise, the sliding rod 20 moves
forward due to expansion of the torsion spring 19, the well 27
disengages from the ball 26, the main O-ring 21 moves to block the
outlet member 13, the stopper 29 moves rearward to block the
forward end of the channel 30, and a next projectile 3 is pushed to
a ready-to-fire position.
[0019] While the invention has been described in terms of preferred
embodiments, those skilled in the art will recognize that the
invention can be practiced with modifications within the spirit and
scope of the appended claims.
