20100206283 | SINGLE-CHAMBER TYPE FIRING MECHANISM OF PAINTBALL GUN - A firing assembly of a paintball gun includes a piston, a spring, and a valve installed in a chamber in a frame of the paintball gun. The piston is a bar-like member having front member, a connection member, and a rear member. The connection member is smaller than the front member and the rear member to form a space thereunder. The valve is in the space to divide the space into a front room and a rear room. The spring urges the piston forward to have the rear member pressing an actuator of the valve that a high pressure gas will escape out of the valve to spurt out of the apertures via the rear room, the channels, and the front room. The high pressure also pressurizes the rear member to move the piston backward and compress the spring. | 08-19-2010 |
20110048395 | Toy gun - A bolt has a cylindrical fit receiving portion. When the bolt slides forward, the rear part of a valve body enters the fit receiving portion. At a closed end opposed to its opening behind the fit receiving portion, a cylindrical body is provided. The cylindrical body lets the interior of the bolt and the exterior of the bolt communicate with each other. The shank of an opening/closing body is slidably placed in the cylindrical body. This opening/closing body has an lid portion at the end of the shank on the fit receiving portion side and a coming-off preventing portion at the outside end of the shank. An opening/closing body spring is placed between the closed end of the bolt and the lid portion and pushes the lid portion toward the fit receiving portion. | 03-03-2011 |
20110146647 | GAS INTAKE CONTROL MECHANISM FOR TOY GUN - A toy gun gas intake control mechanism includes a holder frame, an impact member having an elongated pivoted with its bottom end to the holder frame, a striking block, a pivot axle that pivotally connects the striking block to the top end of the elongated base and a spring member for revering the striking block, a retaining block supported on a spring member in the holder frame and having a retaining notch for retaining the outer end of the pivot axle. When firing a bullet, the bolt body of the toy gun moves forwards, the striking block strikes a seal member to open a gas inlet, and the pivot axle is moved out of the retaining notch of the retaining block for allowing upward displacement of the retaining block. When the bolt body moves backward after firing, the retaining block is forced downwards to the inside or the holder frame by the bolt body, the outer end of the pivot axle is engaged into the retaining notch, and the striking block is returned, causing the seal member to close the gas inlet again. | 06-23-2011 |
20110220088 | BUG KILLING GUN - A bug killing gun includes a compressed gas source fluidly connected to a chamber connected to a barrel. A compressed gas release mechanism is connected to the compressed gas source. A projectile storage magazine stores particulate projectiles and is located adjacent the chamber. A projectile loading mechanism moves the projectiles into the chamber from the magazine. A cocking mechanism is mechanically connected to the compressed gas source, the compressed gas release mechanism, and the projectile loading mechanism. A stock houses and supports the compressed gas source, the compressed gas release mechanism, the barrel, the chamber, the projectile storage magazine, the cocking mechanism and the projectile loading mechanism. When the gun is cocked, the projectile loading mechanism loads a predetermined quantity of the particulate projectiles into the chamber. When the compressed gas release mechanism is activated the projectiles are ejected from the chamber into the barrel and expelled from the gun. | 09-15-2011 |
20120227725 | COMPRESSED GAS GUN HAVING GAS GOVERNOR - A paintball marker has an inline cylinder that includes a gas governor that reduces gas flow from a compressed gas source to a valve area when the bolt is in a firing position; this increases efficiency in the marker because only the required air is used to fire the paintball. This bolt operates independent of the valve pin, which increases cycle speed and enables the governor to open and close at an optimum time in the firing cycle. Further, when the bolt/piston is recocking, the gap between the valve pin and governor valve pin enables low pressure gas driving the piston to start pressurizing the cylinder and driving the piston rearwards without resistance from the high pressure gas. The marker also allows a user to remove the inline cylinder without tools, and provides a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.” | 09-13-2012 |

The inner safety is located below the bolt and has a projection to come into contact with the locking projection of the bolt. A first trigger bar is located below the sear and has a bolt contact part which extends upward at its front end and comes into contact with a cam part of the bolt and a locking projection to lock the sear. A second trigger bar is located below the inner safety and forward of the first trigger bar and has a locking projection to lock the inner safety. | 10-10-2013 |
20140331984 | Quick-Release Valve Air Gun - An air gun with a quick-release pneumatically operated gas valve that includes a piston positioned in a cylinder with one closed end so that the piston may seat against a gas outlet to close the gas valve. A control reservoir filled with gas to a control pressure is formed in the cylinder between the piston and the closed end of the cylinder so that the control pressure acts against the piston to close the gas valve. Opening a trigger valve allows the gas in the control reservoir to escape through an exhaust port, resulting in the gas valve being rapidly opened. | 11-13-2014 |
