Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a modification-preventive bullet feed mechanism for an air gun, and more specifically, a special combination mechanism of the magazine of the air gun and a simulated cartridge case to prevent illegal cartridge case. It relates to something that prevents use and modification and prevents danger.

[Prior Art] Recently, an air gun has been popular as a toy, in which CFC gas (CFC liquid) is injected into a pressure accumulating chamber and a valve of the pressure accumulating chamber is instantly opened to fire a bullet.

There are various types of air guns. For example, a rotary magazine type handgun type has a structure as shown in FIG.

As is clear from the figure, unlike the real gun, the grip portion 51
The accumulator cylinder 52 is built in, the engine portion 54 is activated by pulling the trigger 53, the hammer 55 operates elastically, and the claw 54a of the engine portion 54 momentarily operates the valve 52a of the accumulator cylinder 52. The air is released and the air ejected by the opening is guided to the back of the rotary magazine 57 through the air passage 56 formed inside.

This rotary magazine 57 works in conjunction with the operation of the trigger 53 to move the engine 5
Although it is rotated about the shaft portion 57a by 4, the cylindrical simulated cartridge case 58 is loaded from the rear end side into the bullet feed hole of the rotary magazine 57. A packing 58a is fitted in the simulated cartridge case 58, and a bullet 59 is press-fitted into the packing 58a.

Therefore, when the air is instantaneously guided to the back of the rotary magazine 57 as described above, the bullet 59 is pressed through the hole 58b of the simulated cartridge case 58, and the bullet 59 is pressed from the packing 58a toward the gun cavity 60. Release and urge to the gun cavity 60
The bullet 59 is fired from. The barrel portion 60 is the barrel portion 6
The spring 62 provided between the rotary magazine 57 and
It is biased to the side so that the contact portions of the vent hole 56, the rotary magazine 57, and the simulated cartridge case 58 are brought into close contact with each other to prevent air pressure leakage.

By the way, this type of air gun is designed as close to a real gun as possible in terms of design and apparent operating state in order to add charm as a model gun, but if it is designed close to a real gun, it can be easily modified. Therefore, there is a possibility that an unauthorized modification may be performed so that a bullet can be fired using gunpowder, which is extremely dangerous.

Therefore, in the air gun manufacturing / sales industry, various regulations and standards are voluntarily established under the guidance of administrative agencies to prevent modification. For example,
The air pressure is below a predetermined pressure, the gun body (including the rotating magazine and the simulated shell case) is made of plastic,
The rotary magazine 57 cannot be disassembled without destroying the product, and the insert steel 6 cannot be disassembled at the collision position of the hammer 55 in order to prevent the shooting needle device from being attached.
3 insert, the bullet is made of plastic, the diameter is more than a predetermined value, the tip has a roundness,
It is stipulated that the kinetic energy at the time of firing a bullet is below a predetermined value.

[Problems to be Solved by the Invention] However, there is an example in which the simulated shell pod 58 is modified to fire a bullet by gunpowder even if such modification prevention regulations are made. For example, as shown in FIG.
It has been reported that the hole 58b of No. 8 is filled with gunpowder, the firing pin 65 is inserted behind the hole 58b, and the gun 59 is exploded by the action of the firing pin 65 by the air pressure so that the bullet 59 is fired. There is.

Such modification makes the power of launch extremely strong, and since the rotary magazine 57 and the like are made of plastic and weak in strength, there is a possibility of causing an explosion of the gun body, which is extremely dangerous.

Therefore, the present invention was created for the purpose of providing a special combination mechanism of a magazine and a simulated case which can prevent dangerous modification of the air gun.

[Means for Solving the Problem] In the present invention, a plastic simulated cartridge case in which a bullet is press-fitted into a packing part is loaded into a feed hole of a plastic magazine, and a trigger is pulled to move the accumulator chamber to the back of the simulated cartridge case. In an air gun that releases air instantaneously, releases and urges the bullet from the press-fitted state by the air pressure, and fires it through the gun cavity, a coil made of hard metal material is wrapped around and the inner diameter is larger than the outer diameter of the bullet A magazine in which the sleeve part is integrally molded from the end of the gun cavity toward the inside of the bullet hole, a tube part inserted into a gap between the inner surface of the magazine hole and the outer peripheral surface of the sleeve part, and a packing part into which a bullet is press-fitted. Consisting of a simulated case with
(EN) A modification preventing type bullet feeding mechanism for an air gun, characterized in that a simulated cartridge case is inserted into a gap between an inner surface of a bullet hole of the magazine and an outer peripheral surface of a sleeve portion to load the simulated cartridge case into the magazine.

[Operation] In the present invention, the sleeve part integrally molded in the bullet feed hole of the plastic magazine penetrates the bullet that has been released from the press-fit state by the air pressure and is urged, but with the simulated shell case loaded. Then, it fits inside the tube of the simulated case.

Therefore, it becomes impossible to pack the gunpowder or provide the firing pin in the tube portion of the simulated cartridge case.

On the other hand, if the sleeve part of the magazine is molded only from plastic, processing such as removing the sleeve part from the inside of the shell hole is performed using a drilling machine, etc., and the modified simulated shell case as shown in FIG. May be loaded.

The coil of hard metal material cast into the sleeve serves to prevent this modification, making it impossible to remove the sleeve without destroying the magazine.

The present invention can be applied not only to a rotary magazine type, but also to a combination mechanism of a single-shot type air gun magazine such as a rifle and a simulated shell case.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

The magazine of the air gun according to the present embodiment is used for the rotary magazine type tendon-type air gun shown in FIG. 7, and its axial sectional view is shown in FIG. 1 and the side view of the simulated drug case loading side is shown in FIG. FIG. 3 shows a sectional view taken along the line AA in FIG.

The magazine 1 is integrally plastic-molded by using a mold, and the sleeve portion 4 is formed from the gun cavity side end 2 thereof in the bullet feed hole 3 direction. Then, when the magazine 1 is plastic-molded, the steel coil 5 that has been hardened is cast into the sleeve portion 4. That is, it has a structure in which the sleeve portion 4 in which the coil 5 is cast is formed in each of the bullet feed holes 3 (6 pieces) of the magazine 1.

The inner diameter D of the sleeve portion 4 has a diameter larger than the outer diameter of a bullet (BB bullet) 13 to be press-fitted in the below-mentioned simulated shell case 10, and the length L of the sleeve portion 4 is equal to that of the simulated shell case 10. A part of the packing portion 12 is also set to be located inside the bullet feed hole 3 when loaded.

On the other hand, FIG. 4 shows a cross-sectional view of the simulated cartridge case 10, in which the tube portion 11 and the packing portion 12 are integrally plastic-molded, and the rubber packing 12a is fitted to the packing portion 12 side. And the same rubber packing 12
A bullet 13 is press-fitted inside a. Reference numeral 12b denotes a flange portion formed on the packing portion 12, and is a portion that contacts the rear end surface of the magazine 1 when the simulated shell 10 is loaded into the magazine 1 and allows the simulated shell 10 to be attached and detached. .

FIG. 5 is a sectional view showing the state where the magazine 1 is attached to the rotary magazine type pistol type air gun and the simulated cartridge case 10 is loaded. In this figure, the parts denoted by the same reference numerals as those in FIG. 7 indicate the same parts as those explained in FIG.

The loading of the simulated shell case 10 into the magazine 1 is performed as shown in FIG. 6. First, the shaft 57a, which is usually set in the yoke portion, is tilted to the side and the magazine 1 is pulled out to the side of the gun body. , The simulated cartridge case 10 is inserted into each of the supply holes 3 of the magazine 1. In the case of the structure in which the shaft portion 57a cannot be tilted to the side, a rotary lid (not shown) provided on the rear side of the magazine 1 is opened to open the bullet feed hole 3 and to imitate the simulated case. 10 will be inserted.

In this case, the pipe portion 11 of the simulated cartridge case 10 is provided with the bullet feed hole 3 of the magazine 1.
Is inserted into a gap 6 formed between the inner peripheral surface of the sleeve portion 4 and the outer peripheral surface of the sleeve portion 4, and the portion other than the flange portion 12b is inserted into the bullet feed hole 3
Once inside, loading is complete.

The operation of firing the bullet 13 is similar to that described in the prior art. In FIG. 5, the engine portion 54 is actuated by pulling the trigger 53 to instantaneously move from the accumulator cylinder (not shown) to the vent hole 56. Air pressure is supplied, the bullet 13 press-fitted into the packing portion 12 of the simulated cartridge case 10 is released and urged by the air pressure, and the bullet 13 is fired from the inner hole 4a of the sleeve portion 4 of the simulated cartridge case 10 through the gun cavity 60. .

As is apparent from FIG. 5, there is no difference in appearance from the conventional air gun in the state in which the simulated shell case 10 is loaded in the magazine 1. In addition, the appearance of the simulated drug case 10 is almost the same as that of the conventional simulated drug case 58 (see FIG. 7).

On the other hand, according to the combination mechanism of the magazine 1 and the simulated shell case 10 of the present embodiment, the sleeve portion 4 of the magazine 1 has the tube portion 1 of the simulated shell case 10.
If it does not fit inside 1, fill the cartridge case 10 with the shell case 3 of the magazine 1.
Since it cannot be loaded into the simulated shell case 10, it is impossible to incorporate gunpowder or a firing pin element in the tube portion 11 of the simulated shell case 10.

Further, when a modification for deleting the sleeve portion 4 of the magazine 1 in order to load the simulated shell case capable of incorporating the gunpowder, the firing pin element, etc., the sleeve portion 4 was hardened as described above. Since the steel coil 5 is surrounded by casting, processing becomes difficult and the magazine 1 is destroyed,
Modification is impossible.

[Advantage of the Invention] As described above, according to the present invention, a magazine having a sleeve portion formed by casting a hard metal material inside the bullet feed hole, and a pipe portion fitted in the gap between the bullet feed hole inner surface and the sleeve portion are provided. By forming a combination of the simulated case pods, it becomes impossible to use the case pods that lead to a dangerous accident, and it is impossible to modify the magazine for using the pods, thereby providing an air gun as a safe model gun for play.

In addition, the present invention has the advantages that it does not prevent the air gun from forming a design close to that of a real gun, and that the external appearance of the air gun is similar to that of a conventional one.
