US Patent 8113188 Toy air gun

A toy gun includes a body, a piston adapted to move relative to the body between an extended position and a retracted position and to be moved rapidly toward the retracted position during a firing stroke. A number of firing chambers each receive a projectile and air compressed by the piston during a firing stroke to fire the projectile from the toy gun. An air delivery mechanism conveys the compressed air to one of the firing chambers and co-operates with the piston to advance as a result of piston movement to a configuration whereat it can convey compressed air to another of the chambers.
