International ClassF41B 011/06Foreign Application Priority Data1993-10-08 JPAbstractA model gun with automatic bullet supplying mechanism comprises a slider provided to be movable along the barrel, a movable member provided to be movable along moving directions of the slider between a bullet holding chamber provided at the back of the barrel and a pressure receiving portion fixed in the slider to be positioned at the back of the barrel and movable with the slider, and a gas passage controller provided to be movable in the movable member. The gas passage controller is operative selectively to control a first gas passage extending from a pressure accumulating chamber through the movable member to the bullet holding chamber to be open so that gas discharged from the pressure accumulating chamber is supplied through the first gas passage to the bullet holding chamber and to control a second gas passage extending from the pressure accumulating chamber through the movable member to the pressure receiving portion to be open so that gas discharged from the pressure accumulating chamber acts through the second gas passage on the pressure receiving portion to cause first the slider to move back and then the movable member also to move back for making preparations for supplying the bullet holding chamber with a sham bullet from a magazine for containing sham bullets.Field of SearchBy valve meansFor continual projection of successive projectiles (e.g., for "rapid fire", etc.) With control for discharge of fluid pressure With check valve permitting recharge, and control valve for discharge, of fluid pressure To store pressure in valved container For discharge of pressure from removably mounted cartridge Opened by fluid pressure-actuated means Opened by spring-actuated means FLUID PRESSURE Trigger or releasing mechanism | |
