Definitions
- the invention relates to airsoft guns and more particularly to a firing device of an airsoft gun.
- Airsoft guns use an expanding gas, such as compressed air or carbon dioxide (CO 2 ) to propel plastic pellets through the barrel. Airsoft guns can fire in rapid succession a relatively large number of plastic pellets in a short period of time. A magazine stores the plastic pellets until the balls are delivered to the gun firing chamber. The guns use compressed gas as the propellant, and are usually triggered by a user squeezing a conventionally shaped gun trigger. When the gun user repeatedly squeezes the trigger, the gun should continue to fire plastic pellets as rapidly as possible. Airsoft guns most are either semi-automatic, where each time the trigger is pulled a plastic pellet is fired, or fully automatic, where the balls are fired as quickly as the gun is capable of for as long as the trigger is pulled.

Description
- 1. Field of the Invention
- The invention relates to airsoft guns and more particularly to a firing device of an airsoft gun.
- 2. Description of Related Art
- Airsoft guns use an expanding gas, such as compressed air or carbon dioxide (CO2) to propel plastic pellets through the barrel. Airsoft guns can fire in rapid succession a relatively large number of plastic pellets in a short period of time. A magazine stores the plastic pellets until the balls are delivered to the gun firing chamber. The guns use compressed gas as the propellant, and are usually triggered by a user squeezing a conventionally shaped gun trigger. When the gun user repeatedly squeezes the trigger, the gun should continue to fire plastic pellets as rapidly as possible. Airsoft guns most are either semi-automatic, where each time the trigger is pulled a plastic pellet is fired, or fully automatic, where the balls are fired as quickly as the gun is capable of for as long as the trigger is pulled.
- Plastic pellets are relatively round and have an exterior formed from a semi-rigid gelatinous compound. The gelatinous compound is known to be affected somewhat by variables such as temperature and relative humidity. During a firing sequence, plastic pellets on occasion lodge against each other or other objects and block the passageway to the firing chamber, resulting in a jam. While jamming is not new, knowledge from explosive munitions magazines is of little use with the very different plastic pellets.
- The invention described below aims to minimize jams when using an airsoft gun.
- It is therefore one object of the invention to provide a firing device of an airsoft gun comprising, in combination: a magazine provided with a plurality of plastic pellets; a butt including a chamber, a passage, a front section, a sleeve member, a port at a front end of the sleeve member, an intermediate space in the chamber, a main disc at a rear end of the sleeve member, a hole in a rear of the sleeve member communicating the sleeve member with the intermediate space, a tunnel, and a passageway; a firing mechanism disposed at a joining portion of the chamber and the magazine and including a sleeve, a stem in the sleeve and having a rear flange member, a disc member in a front of the sleeve and releasably secured to a forward end of the stem, a plurality of exit ports at the disc member, a flange member at a rear end of the stem, a flange in a rear of the sleeve having an area greater than that of the flange member, a plurality of ports in a rear of the stem, and a space member disposed between the flange and the chamber; a valve disposed adjacent to the sleeve and communicating with the front section, the valve including a body and a moveable stem member; and a high pressure air canister disposed in a rear end of the butt and including a passage communicating with the chamber, and an outlet, the high pressure air canister communicating with the valve via the passage; wherein the tunnel is disposed between the passage and the high pressure air canister and communicates with both; wherein the stem member is configured to move by the pressurized air from the space member; and wherein in a firing operation the valve is opened by pressurized air supplied from the high pressure air canister, the firing mechanism is activated to move rearward to push the sleeve member rearward, the main disc is configured to stop the moving sleeve from moving further rearward, a topmost one of the plastic pellet is pushed to dispose at a front end of the chamber, a forward end of the stem blocks the port, the pressurized air passes the sleeve and flows back to the intermediate space, the valve is closed to stop the pressurized air from flowing to the front section, the pressurized air pushes the firing mechanism forward, the valve is opened by the pressurized air opened by pressurized from the passage, the firing mechanism moves forward to cause the flange member to block the pressurized air from flowing out of the outlet, the pressurized air in the intermediate space flows through a path between the sleeve member and the stem and further flows through the ports to enter a space between the sleeve and the stem, the pressurized air passes through the port to enter the exit ports, and the pressurized air pushes the plastic pellet out of the chamber to fire.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

FIG. 1 is a longitudinal sectional view of a butt, a magazine, and a firing mechanism of an airsoft gun incorporating a firing mechanism according to the invention, where pressurized gas has not supplied to the firing mechanism; -
FIG. 2 is an enlarged view of the portion a shown inFIG. 1 ; -
FIG. 3 is a view similar toFIG. 1 , where pressurized gas has supplied to the firing mechanism; -
FIG. 4 is an enlarged view of the portion b shown inFIG. 3 ; -
FIG. 5 is a view similar toFIG. 1 , where the plastic pellet has been fired; and -
FIG. 6 is an enlarged view of the portion c shown inFIG. 5 . - Referring to
FIGS. 1 to 6 , an airsoft gun in accordance with the invention comprises the following components as discussed in detail below. - A
butt 1 comprises achamber 10. Afiring mechanism 2 is provided at a joining portion of thechamber 10 and amagazine 5 provided with a plurality ofplastic pellets 50. Thefiring mechanism 2 comprises asleeve 21 and astem 22 in thesleeve 21. Avalve 3 is provided adjacent to thesleeve 21. Thevalve 3 comprises abody 30, achannel 32, and astem member 31 moveably disposed in thechannel 32. A highpressure air canister 4 is provided in a rear end of thebutt 1. Theair canister 4 comprises apassage 40 communicating with thechamber 10. Atunnel 18 is provided between thepassage 40 and theair canister 4 and communicates with both. Theair canister 4 communicates with thevalve 3 via apassage 11 in thebutt 1. Afront section 12 of thebutt 1 communicates with both themagazine 5 and thevalve 3. Ahole 17 in the rear of thesleeve member 13 communicates thesleeve member 13 with thespace 15. - After activating the
air canister 4, thevalve 3 is opened by high pressure air supplied from theair canister 4 via thepassage 11. Apassageway 19 is adjacent to thevalve 3 and serves as a downstream of thevalve 3. Next, thefiring mechanism 2 is activated to push asleeve member 13 in thebutt 1 rearward.

Amain disc 16 at a rear end of thesleeve member 13 is adapted to stop the rearward movingsleeve 21 from moving further rearward after rearward moving thefiring mechanism 2. The topmostplastic pellet 50 is then pushed upward to dispose at a front end of thechamber 10. Next, aforward end 24 of thestem 22 blocks aport 14 at a front end of thesleeve member 13. Pressurized air thus flows back to anintermediate space 15 in thechamber 10 by passing thehole 17. - An individual may pull a trigger (not shown) to close the
valve 3. Next, pressurized air is stopped from flowing to thefront section 12. Further, pressurized air is directed to push thefiring mechanism 2 forward to cause theflange member 26 to allow pressurized air to flow out of anoutlet 41 of thepassage 40. Pressurized air in thespace 15 flows through a path between thesleeve member 13 and thestem 22 and further flows through a plurality ofports 28 in the rear of thestem 22 to enter a space between thesleeve 21 and thestem 22. And in turn, pressurized air passes through theport 14 to enter a plurality ofexit ports 25 at afront disc 23 of thesleeve 21. Further, pressurized air pushes theplastic pellet 50 out of thechamber 10 to fire. - 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.
