Abstract
A gun, which compresses a spring during cocking and uses the air accelerated by the spring to propel a projectile during firing, incorporates several safety features. The size of the handle makes it impossible for children to operate. The trigger cannot be moved to its firing position unless the gun is cocked, the gun housing is closed, and a manual safety button is actuated during firing. To prevent unintended projectiles from being inserted into the barrel, the front of the barrel is blocked except during firing and the rear of the barrel is blocked at all times by either the projectile-carrying magazine or a barrel block.
