Abstract: A toy vehicle-projecting gun assembly in which the vehicle is normally latched on an inclined ramp with its rear wheels raised and free to turn, the ramp extending from the front end of the power chamber of the gun. Joined to the rear end of the chamber is a gun stock provided at its underside with a power trigger operated by the trigger finger of the player and on its topside with a firing button operated by the player's thumb. When the trigger is actuated, it acts through a gear train disposed in the power chamber to turn a drive gear mounted on the rear wheel axle, the drive gear being coupled to an energy-storing flywheel functioning as the vehicle motor. After the motor is revved up by repeated trigger actions, the player presses the firing button which operates an unlatching mechanism to release the vehicle which then shoots down the ramp.
