  • Patent number: 7861701
    Abstract: An improved shooting device for air guns and paintball guns comprises a gun barrel sheathed into a sliding base of a breech of a gun, a tension spring installed at the front end, a bullet supplying device installed at the rear end, an opener connected to the rear of the bullet supplying device, and a bullet supplying hole formed at the bottom of the bullet supplying device and interconnected with the bullet feeding hole of a handle type magazine. The gun barrel includes an elastic turning base pivotally connected thereon, a pushing groove formed at the rear edge of the turning base, a sliding surface formed at the bottom of the turning base, and the pushing groove and a pushing protrusion disposed at the top of a trigger are engaged, so that when the trigger is pulled, the pushing protrusion at the top of the trigger pushes the pushing groove of the turning base, such that the turning base drives the gun barrel to compress the tension spring and produce a forward displacement.

  • Patent number: 7726293
    Abstract: A continuous firing type trigger structure of a toy gun (air soft gun/BB-gun) includes a valve body disposed behind the output port of a magazine clip in air communication with the gas outlet of a high-pressure gas can, an enclosed socket connected to the rear side of the valve body, a valve tube inserted through the valve body, a spring that pushes the valve tube forwards to keep the air inlet of the valve tube not in communication with the inside space of the valve body, and a piston inserted into the enclosed socket and fixedly connected to a sliding shell on the outside of the toy gun such that the valve tube is moved with the piston forwards (or backwards) to let a high pressure gas be discharged out of the high-pressure gas can into the valve tube to drive an airsoft gun out of the toy gun and to force the piston and the sliding shell backwards after triggering of the trigger of the toy gun, for enabling the piston and the sliding shell to be immediately returned by a return spring for a next firing ope

  • Patent number: 7603996
    Abstract: A structure for changing gas cylinder for air guns and paintball guns including a bottle frame having a lateral through hole on a gun handle, a prop screwed at the bottom of the bottle frame for moving the gas cylinder upwardly and downwardly, a valve installed at the top of the bottle frame and connected to a gas supply valve tube, a track disposed along both sides of the handle and latched by an embedded member of a U-shape handle cover. The U-shape handle cover is movable along the track between open and closed positions. The gas cylinder can be unloaded from and loaded into the bottle frame without removing the prop or the U-shape handle cover. The U-shape handle cover can be pushed forward along the track to completely seal the pressurized gas cylinder to form a handle without completely removing the prop or the U-shape handle cover.

  • Patent number: 7353815
    Abstract: The present invention describes a cartridge magazine assembly for air guns and paintball guns, and the magazine is designed as an independent device inserted into a breech of a gun to connect a feeder of the gun. The magazine has a vertical feeding chamber at the front of the magazine, and a casing can be added onto the feeding chamber for feeding paintballs or pellets of different sizes, and a feeder spring is installed to pop a feeder bracket to define the feeding device. A bottle frame with through holes is defined at the rear of the magazine, a support is secured into the bottom of the bottle frame by a screw, and the support can be moved up and down manually or by a tool.

  • Publication number: 20060288990
    Abstract: An improved structure for changing gas cylinder for air guns and paintball guns includes a bottle frame having a lateral through hole on a gun handles, a prop screwed at the bottom of the bottle frame and turned by hands to be moved vertically up and down, a valve installed at the top of the bottle frame and connected to a gas supply valve tube, a track disposed along both sides of the handle and latched by an embedded member of a U-shape handle cover. After the U-shape handle cover is sheathed along the tracks and blocked by the bottom edge of the track, the bottle frame can be unloaded without removing the U-shape handle cover. The prop can be screwed downward to unload or install the pressurized gas cylinder, or screwed upward to push the pressurized gas cylinder to move upward, such that the gas cylinder is combined with the valve and expedites the pressurized gas to be discharged from the valve for shooting the gun.
