Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cartridge case for a toy gun that includes a spring for firing a bullet.

Conventional cartridges for toy guns are mainly fired using air pressure, but in this method, the piston is airtightly fitted, and the spring latching and release device that presses the piston is structurally complex, so it is difficult to manufacture. There is an inconvenience that requires skill. The present invention aims to provide a cartridge case for a toy gun that can eliminate such disadvantages and inconveniences. To explain the present invention with reference to an embodiment shown in the drawings, 1 is an outer cylinder, and 2 is an outer cylinder. a bottomed inner cylinder having an outer diameter that matches the inner diameter of the cylinder;
Reference numeral 3 denotes a recessed hole provided on the bottom surface of the outer cylinder, and a presser element 4 is slidably installed inside this recessed hole. The bottom of the 07, which is fixed to the plate, is a cone-shaped bullet firing coil nook on the head, and the lower end is placed on the bottom plate of the inner cylinder! The device was installed. 8
are long grooves of a required width provided on the opposing surfaces of the inner cylindrical walls on both sides of the coil spring, into which the bullet pieces 9 are respectively fitted, and at the upper ends are curved edges 11 provided on the outer periphery of the proximal end of the bullet 10, respectively. A locking pawl 12 is provided, and 013 is a long groove-shaped gap provided in the outer cylinder wall so that the upper half of the ammunition piece 9 can be bent backwards. Reference numeral 14 denotes a convex portion for preventing the spring from popping out, which is provided inside the lower part of the ammunition piece 9 in parallel with the inclined side of the coil spring 7.

Reference numeral 15 denotes a sliding elongated hole that engages with a guide protrusion (not shown) provided inside the outer cylinder, so that the position of the upper half of the ammunition piece 9 and the gap 13 provided in the outer cylinder are always aligned at 11II. This is to avoid @shi.

Since the present invention is constructed as described above, when the bullet 10 is not loaded, the coil spring 7 is maintained in the extended state as shown in FIG. When the bullet is press-fitted, the locking claw 1 provided at the upper end of the bullet piece 9 will fit into the curved edge 11 provided on the bullet, as shown in FIG.
2 is locked so that the bullet is held at the open end of the cylinder as shown in FIG. When the cartridge case loaded with a bullet is inserted into the magazine of the toy gun, or inserted into the cartridge case fitting part of the gun body and the rear hammer is actuated to strike the presser 4, it is integrated with the bottom plate of the inner cylinder 2. The pusher, which is connected to the The upper half where the gap 13 is provided is the outer side, that is, the gap 1
3, the locking portion 12 of the bullet is disengaged from the curved edge 11 of the bullet, and the bullet is fired outward by the elastic force of the coil spring 7.

After the bullet has been fired, the bullet piece 9 returns to its normal state again, and the inner cylinder and presser 4 are also in the state shown in Figure 1.If the bullet is again pressed into the open end of the cylinder, it will appear as shown in Figure 2. In this case, there is almost no danger since the bullet fragments will not be fired without permission unless the pusher 4 is fully pressed. The coil spring 7 is subject to the action of jumping out of the inner cylinder ↓9 at the moment the bullet is fired, but if the bullet piece 9 is provided with an inclined side 14+' and the coil spring is held in place as shown in the figure, it will not fly out. Preventing the coil spring from popping out is not necessarily limited to the above-mentioned device; one method is to fix the proximal end of the coil spring to the bottom of the inner cylinder; in either case, the coil spring is always held in the inner cylinder. Because of this, there is no chance of the coil spring popping out or getting lost. - Unlike conventional cartridges that use pneumatic pressure, the present invention has a simple structure and does not require precision, so it is easy to manufacture, and in particular, it is possible to manufacture cartridges with a smaller outer diameter than conventional pneumatic cartridges. Since it can be easily loaded with external bullets, it is suitable as a cartridge for toy guns, and there is no risk of it being modified.

Claims (1)

[Claims] An inner cylinder whose outer diameter matches the inner diameter of the outer cylinder is fitted inside the outer cylinder, and the front end is integrally connected to the bottom of the inner cylinder.The rear end of the presser has a concave hole formed in the bottom of the outer cylinder. A coil spring of a required length is installed inside the inner cylinder so that it can be slid back and forth, and a suitable device is used to prevent it from popping out. Long grooves are provided in the cylindrical wall at positions opposite to each other on both sides of the coil spring in the longitudinal direction. Each bullet piece is fitted into the long groove, and when the bullet is pressed into the opening of the cylinder without compressing the coil spring, a locking pawl is formed at the upper end that engages with a curved edge provided on the outer periphery of the proximal end of the bullet. A toy characterized in that a gap is provided in the outer cylinder wall behind the upper half of the ammunition piece provided with the locking claw so that each of the ammunition pieces can be bent backward. gun cartridge 0
