Patent ID: 7721722

Claim:
A toy gun for launching a projectile in response to pressurized air, the toy gun being powered by water under pressure supplied from an available source of water under pressure, the toy gun comprising: a barrel for launching the projectile; a firing chamber for being coupled with the projectile to be launched, the firing chamber communicating with the barrel; an air chamber; a trigger valve located between the firing chamber and the air chamber for selective movement between a first position, wherein the trigger valve closes communication between the firing chamber and the air chamber, and a second position, wherein the trigger valve opens communication between the firing chamber and the air chamber; an air compressor communicating with the air chamber for supplying air under pressure to the air chamber while the trigger valve is in the first position; an actuator coupled with the air compressor for operating the air compressor to supply air under pressure to the air chamber while the trigger valve is in the first position; and a water coupling arrangement for coupling the actuator with the source of water under pressure; the actuator being arranged for operation in response to water under pressure such that upon introducing water under pressure to the actuator, the actuator will operate the air compressor to supply air under pressure to the air chamber while the trigger valve is in the first position, whereby upon coupling of a projectile with the firing chamber, subsequent operation of the trigger valve to selectively move the trigger valve to the second position and thereby open communication between the air chamber and the firing chamber will release air under pressure from the air chamber to the firing chamber for launching the projectile along the barrel.
