AUTOMATIC AIR GUN

摘要

PURPOSE:To obviate the need of the carriage of a tank for miniaturization and high performance of the same by providing a piston in which air is sucked into a cylinder and simultaneously pressure is stored in a compression spring and further a bullet is shot by injected air, and further providing a rotary wheel for forcing the piston to withdraw while being interlocked with the piston, and a driving motor for the rotary wheel. CONSTITUTION:With the rotation of a rotary wheel 23 by a motor 27, a tooth part 24 and a rack 20 force a piston 13 to withdraw for storage of pressure in a compression spring 17, whereby the piston is instantaneously forced to advance at a non-tooth part 25 and a concave part 22 to compress air in a cylinder and jets the same from a jetting outlet 12 for shooting a bullet b. Further, with the rotation of the rotary wheel 23 a bullet supply part 4 is interlocked to cause a slide arm 45 engaged with a pin like engagement part 48 to slide against a spring 49, whereby a bullet supply outlet 41 is brought into synchronization with the withdrawal of the piston 13 for storage of the bullet. Provided a changeover lever 37 is set to a single shot position, engagement of a shear 33 with a trigger 32 is disengaged every two shot in response to the rotation of a rotary shaft. Provided the changeover lever 37 is changed over to a running fire position, a tappet arm 35 is prevented from engaging with the sprung shear 33 whereby the motor 27 is successively rotated as long as the trigger 32 is drawn, and hence a series of shooting operations are continued repeatedly.
