20100199960 | REUSABLE PELLET SHOOTING GRENADE - The present invention is an improved grenade which launches a plurality of pellet projectiles. The grenade includes a housing containing at least one spiral launch tube, said launch tube having a breech end and a muzzle end. A plurality of projectiles are loaded in the launch tube between the breech and muzzle ends. The grenade includes a gas reservoir for storing a compressed gas coupled to the breech end of the launch tube. A valve is interposed between the reservoir and the breech end of the launch tube for controlling the flow of compressed gas from the reservoir to the breech end of the launch tube. The valve is moveable between a closed state and an open state wherein said compressed gas enters the breech end of the launch tube to propel the projectiles from the muzzle end, the valve being biased towards its open state. The grenade also includes a trigger mechanism coupled to the valve, the trigger mechanism operating between a locked state wherein the trigger mechanism holds the valve in its closed state and an unlocked state wherein the valve is free to move into its open state. | 08-12-2010 |

20110083653 | CARTRIDGE-BASED AIR GUN - A cartridge-based air gun that fires a BB bullet or a resin bullet inside a cartridge using compressed gas, includes an engaging structure of an extractor that enables blowback and the automatic ejection of the cartridge. An extractor, which engages with a rim that is formed at the rear end of a cartridge loaded in a chamber, is pivotally provided on a side portion of a cylinder so as to be rotatable. A claw portion formed at the tip of the extractor engages with the rim of the cartridge by the urging force of a spring provided between the extractor and the cylinder. A slide moves rearward while the cartridge is held inside the chamber. As the cylinder moves rearward with the stopping of the supply of compressed gas from a gas reservoir, the cartridge comes into contact with an ejector, is released from the engagement by the extractor, and is ejected from the chamber. | 04-14-2011 |
20110220087 | Low Cost Rescue Launcher System - A rescue launcher system includes a reusable launcher and a one-time-use, pre-packed payload cartridge removably secured to the reusable launcher. The payload cartridge includes a plastic canister, a pressurization system located within the canister and selectively activated by reusable launcher, and a payload located within the canister and which is launched to a remote location upon actuation of the pressurization system. An actuation grip of the launcher selectively actuates the pressurization system, and an interlock is adapted to prevent actuation of the pressurization system unless the interlock and the actuation grip are simultaneously actuated. The payload can be a buoyancy device including a sealed tube and deflated foam within the sealed tube which inflates using internal vacuum after launch of the buoyancy device. | 09-15-2011 |
20120298088 | SYSTEM AND METHOD FOR DELIVERING A PROJECTILE TOWARD A TARGET - Some embodiments relate to a system and method for delivering a projectile toward a target. The system includes a launcher and a propulsion system positioned within the launcher. The propulsion system includes a gas generator that produces enough gas within a certain period of time to direct the projectile from the launcher toward the target. The system for delivering a projectile may further include a targeting system that collects data regarding the location of the target. In addition, the launcher may include a venting system that exhausts a particular amount of gas from the launcher in order to direct the projectile from the launcher at a desired velocity based on data received from the targeting system. | 11-29-2012 |
20140251296 | TWO-PHASE PROJECTILE WITH A PROXIMAL COMPRESSION CHAMBER - A man-powered system for pneumatically launching a pellet cluster includes a cartridge for holding the pellet cluster. A hollow propulsion shaft receives the cartridge for substantially free travel back and forth in the shaft to establish a variable-volume compression chamber in the shaft, between the cartridge and a closed end of the shaft. When a driving force acts to launch the combination of cartridge and shaft, the cartridge moves to compress gas in the compression chamber for a subsequent expansion that will propel the cartridge forward through the shaft. After launch, the compressed gas acts to separate the pellet cluster from the cartridge and to provide a pneumatic assist that increases the velocity of pellets after separation. | 09-11-2014 |
