Patent ID: 8113188

Claim:
A toy gun, comprising: 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 plurality of firing chambers in a circular array and each adapted to receive a projectile and to receive air compressed by the piston during a said firing stroke to fire the projectile from the toy gun; an air delivery mechanism adapted to convey the compressed air to one of the firing chambers and co-operating 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; a pressure chamber situated between the firing chambers and the piston and via which the compressed air is conveyed to the firing chambers; and the air delivery mechanism comprises a disc rotatable within the pressure chamber, the disc having a port with a check valve across it, the port aligned with one of the firing chambers, and means for rotatably indexing the disc to align the port with another one of the firing chambers.
