ある。 The present invention will be explained below with reference to the embodiments shown in the drawings.
A piston 3 is fitted through the bottom cover 5, and a bottom cover 5 having a cylindrical projection 4 on the upper surface is fixed to the opening at the lower end. At the center of the bottom surface of the piston 3, a hook-shaped locking pawl 6 and a locking piece 7 whose lower side is tapered are provided.
It is not necessary to provide one piece on the central lower surface, but two pieces may be provided back to back. Inside the upper end opening of the cylindrical projection 4 through which the lower end of the locking piece 7 enters and exits, there is provided a locking step 8 on which a hook-shaped locking pawl 6 at the lower end of the locking piece is latched. A boar-shaped push piece 10 having an outer diameter that matches the inner diameter of the opening is fitted into the opening 9 at the center of the bottom surface of the bottom cover 5, and this pushes the upper edge 10a.
facing close to the locking step 8 in the opening, and this push piece is provided with locking pieces 11 of a predetermined length that are integrally formed with the piece body along both outer walls or one outer wall, A locking pawl 12 formed at the upper end of this locking piece is configured to lock onto the upper edge of the cylindrical projection 4 as shown in FIG. The locking piece 11 is engaged in a locking groove 13 provided along the inner wall of the opening of the cylindrical projection, as shown in FIG. 7, to prevent the push piece from rotating freely. 14 is a coil spring, and 15 is a bullet.

ことなく、安定保持されるのである。 Since the present invention is configured as described above, when the piston is pressed and slid by the pressing rod inserted from the front end opening of the cartridge case, the coil spring 14 is moved to the first position.
As shown in the figure, the piston is compressed, and the locking piece 7 provided on the lower surface of the piston is fitted inward from the upper end opening of the cylindrical projection 4, and the hook-shaped locking pawl 6 at the lower end of the cylindrical projection 4 is compressed. It is locked by a locking step 8 provided inside the upper end opening, and the piston is restrained inside the cartridge case against the elastic pressure of the coil spring, as shown in FIG. After that, the push rod is removed, the bullet 15 is inserted into the opening of the cartridge case, and the cartridge case is loaded into the rear end of the gun barrel.After that, when the trigger of the gun is pulled, the hammer of the gun hits the rear end surface of the push piece 10. As a result, the push piece moves forward instantaneously, and the upper edge 10a hits the downwardly inclined surface of the hook-shaped locking pawl 6 formed at the lower end of the locking piece 7. As a result, the locking piece 7 moves forward as shown by the solid line in FIG. From this state, it moves sideways as shown by the chain line, and at that moment the hook-shaped locking pawl 6 separates from the locking step 8 of the cylindrical projection 4 to which it was locked, so the piston instantaneously releases the coil spring. It moves forward with force, compresses the air inside the cartridge, and uses the compressed air pressure to fire the bullet. If the bullet is integrally provided with a locking piece on the bottom as shown in FIG. 8, the bullet will be fired instantaneously by the elastic force of the coil spring. During the above operation, the push piece 10 momentarily advances inside the cylindrical projection from the position shown by the solid line in FIG. 1 to the position shown by the chain line. Since the locking piece 11 is fitted, it will not rotate and displace by itself, and the piston will be moved again, and the locking piece will move forward with the inclined surface of the hook-shaped locking claw at the lower end of the locking piece 7. 11 and is pushed, the locking piece 11 returns the push piece 10 to the old position, and at the same time locks the locking pawl 12 again to the upper edge of the cylindrical projection 4. Thereby, the push piece is stably held without escaping from the opening 9.

る。 As described above, according to the present invention, the cartridge has an extremely simple structure, has a small number of parts, and is easy to assemble, so it has the advantage of being able to be further miniaturized, thereby reducing manufacturing costs. Not only does it have the economical advantage of saving money, but it also has no superiority or inferiority to conventional products in terms of bullet firing function.
It has the advantage of being used as a bullet for various toy guns and further enhancing the effectiveness of this type of cartridge.
