ABSTRACT:
The present invention relates to a safety mechanism for an air gun having a nozzle with an inlet and an outlet and having pressurization capabilities and a release for releasing pressure through the nozzle, wherein the nozzle includes an impediment member (e.g. a launch tube) with which a mating projectile is fitted for shooting. The safety mechanism is located within the nozzle at the nozzle inlet, and prevents or inhibits shooting undesirable projectiles. The safety mechanism includes a valve connected to the nozzle to prevent flow of pressurized air into it when closed and to allow flow of pressurized air when opened; a biasing device for biasing the valve to a closed position; an opening device movably located within nozzle, e.g. within an annular space between a launch tube and the nozzle. This has a first position when a projectile is not located in the nozzle, corresponding to the valve being closed, and has a second position when a projectile is located in the nozzle, corresponding to the valve being opened. When the opening device is moved from its first position to its second position, the valve is moved from its closed position to its open position to permit the shooting of a projectile. The impediment member impedes the insertion and shooting of a non-mating object.
