Description

Technical specification

The present invention has a bullet feed path that is provided in the gun body and supplies bullets inside the magazine to the bullet loading part of the gun body, and is provided in the bullet feed path and the gun body. Is a side feed apparatus in a simulated gun having a configuration in which the Background art

For example, airsoft guns, which are also called force or play guns, use spherical bullets that are commonly called BB bullets manufactured according to certain standards. Some magazines with magazines (magazines) are detachable and others are not. The type of gun that attaches the magazine to the grip part is very common, but the grip position, that is, the magazine position, is separated from the mounting part at the rear of the barrel, and the bullet is mounted from the magazine at the rear part of the barrel. Will be sent through the bullet feed route. The part from this magazine to the rear part of the barrel is a so-called engine part where the trigger, the piston device, and the mechanism for connecting them are densely packed. For this reason, in a simulated gun modeled on a small handgun or the like, it is impossible to incorporate internal mechanisms without destroying the original proportions.

In a simulated gun that requires the incorporation of an internal mechanism without destroying the original proportions, the bullet feed path and other components mounted on the gun body often take a parallel configuration. However, in many cases, modeling has been carried out by taking measures to change the outline to an inconspicuous level. However, since the barrel of a small handgun is short and the magazine and engine department cannot be made too small, problems may still occur even if the above measures are taken. In addition, the structure of the simulated gun is more complicated than that of the actual gun, which is considered to be an obstacle to reproducing the prototype. This In consideration of the various forms and structures of various guns, it was found that they were restricted by the vertical dimension rather than the width (thickness) of the gun. Simulated guns do not require a solid structure like real guns, and the bullets are spherical, so the bullets can be fed more freely than the actual bullets.

Also, in the magazine detachable gun, when the magazine was removed from the gun body, it was inevitable that the bullets remaining in the bullet feed path would fall out. Although the number of bullets spilling from individual guns is not large, the total number of bullets spilling on the user as the magazine is removed is considered a significant amount. If this is left unattended, considering that many of the bullets are made of non-biodegradable plastic, it will eventually lead to environmental destruction, so the manufacturer has decided that some measures should be taken. And we decided to reflect it in the creation of the present invention. Disclosure of the invention

Problems to be solved by the invention

The present invention has been made on the basis of the above circumstances, and the problem is that even if it is a small gun in a simulated gun that has a configuration in which a bullet feed path and other components provided in the gun body are parallel to each other, It is to be able to model while keeping the original pattern without difficulty. Another object of the present invention is to provide a side feed device for a simulated gun that also has a function capable of preventing bullets from spilling from a gun during magazine replacement.

Means for solving the problem

In order to solve the above-described problems, the present invention has a bullet feed path for supplying bullets inside a magazine mounted on a gun body to a bullet loading portion of the gun body, and is mounted on the bullet feed path and the gun body. In a simulated gun that has a configuration parallel to other components, the bullet feed path from the magazine to the bullet unit and the other components mounted on the gun body are arranged side by side almost in the left and right inside the gun body. And

A means is adopted in which the bullet inlet of the bullet receiving portion that receives the bullet pushed out from the bullet feed path is configured to open to a lateral position shifted to either the left or right of the bullet loading portion (claim 1). Invention).

A simulated gun to which the lateral bullet feeding device according to the present invention is applied is a Magaji equipped in the gun body. It is assumed that there is a bullet feed path for the br, and that the path and the other components mounted on the gun body have a parallel configuration. Here, parallel means rather than parallel in mathematics, meaning that they are lined up, and some or all may be lined up. In order to take a configuration in which the above-mentioned bullet feed path and other components are in parallel, even if it is a gun that cannot maintain the original proportion when placed up and down, according to the present invention, the original proportion is A simulated gun that is kept and modeled can be realized. The simulated gun used in the present invention means a gun that is not intended to be killed in contrast to a gun intended for killing, that is, a real gun.

In the present invention, the bullet feed path from the magazine to the loading section and the other components mounted on the gun body are arranged side by side substantially in the left-right direction inside the gun body. The width of the bullet feed path is determined by the diameter of the bullet. Therefore, the numerical value obtained by subtracting the diameter of the bullet, the thickness of the bullet feed path, and the necessary gap from the simulated gun width (thickness) It can be used as the thickness. Since the standard diameter of the bullet assumed in the present invention is 6 mm, it is judged that almost any type of gun can be modeled.

In the above configuration, the bullet inlet of the loading unit for supplying the bullet pushed out from the bullet feed path is opened at a lateral position shifted to the left or right of the loading unit. The side shifted to the left or right side of the loading part means that the bullet inlet is shifted to the left or right with respect to the center of the loading part. In many cases, the bullet feed path is located below or rarely above the bullet loading section. It turns out that

In addition, the magazine installed in the gun body is located on the side where the magazine bullet outlet is shifted to the left or right with respect to the bullet feed path in the gun body. It is possible to adopt a configuration in which a guide member for guiding the testicles to the path is provided so as to be able to appear and retract with respect to the bullet feed path leading to the bullet outlet of the magazine (the invention according to claim 2). This is a configuration in which the magazine is located at a position almost coincident with the center line of the gun body as in the case of the loading section, but as a result, it is displaced relative to the bullet feed path. The guide member feeds bullets to the bullet outlet of the magazine By being able to go out, it also serves as a means to prevent bullets remaining in the bullet feed path from spilling out when manned.

One typical configuration of the simulated gun according to the present invention is as follows: a loading part located at the rear end of a barrel where a bullet is fired, and a piston that is located behind the loading part and injects compressed air to the testicles. An apparatus, a bullet feed path for supplying bullets from the lower side to the lower part of the barrel or the piston apparatus, and on either one of the left and right sides, and the barrel or the piston apparatus. And a trigger member disposed on the lower side and on either the left or right side, and capable of being engaged and disengaged from the lower side with respect to the above-described piston device. Invention). This configuration is the same as that described in the later-described embodiment, but it is obvious that other configurations satisfying the requirements of claim 1 are included in the present invention. In the side feed apparatus according to the present invention, as another component part mounted on the gun body, for example, the piston side engagement is performed in order to retract the piston of the piston apparatus with a firing operation in the drive unit. A trigger member having an engaging counterpart that engages with the portion and advances the piston out of the engagement. The trigger member is provided in the gun body so as to be able to move in the direction in which the piston moves forward and backward, and to move in the direction in which the mating counterpart is removed from the engaging portion. For this purpose, an engagement portion is provided on the piston side, an engagement counterpart is provided on the trigger member side, and when the piston is retracted, the engagement portion and the engagement counterpart are engaged. When the piston is moved forward, the engagement portion and the engagement counterpart portion are disengaged. Brief Description of Drawings

The magazine 3 3 has a bullet storage part 3 5 provided inside in a substantially U shape, and a coil spring that can take a substantially U shape is provided in the bullet storage part 35. Equipped as an elastic body 3 6 to press. The elastic body 3 6 is arranged at a position where the bullet 3 2 is pushed from the testicle exit of the magazine 3 3 toward the testicle feed path 4 1 にて on the front end side, and the base end side is supported by the wall surface of the magazine. 3 7 is a bullet pressing portion at the tip of the elastic body, and 3 8 is a spring receiving portion at the base end of the elastic body.

On the base end side of the elastic body 3 6, the corresponding part of the magazine 3 3 is opened so that the elastic force can be used for biasing the trigger member 15, and the protrusion 3 of the spring receiving part 3 8 is opened there. 8 A pressurizing member 40 that can be pushed by a and protrudes outward from the magazine 33 is provided. The pressure member 40 is rotatably supported by the magazine 33 at the rear portion 40a, and the arc-shaped groove 38b provided in the magazine 33 at the front portion 40b. The direction in which the engagement portion 2 7 and the engagement counterpart portion 17 engage with each other is in contact with the protrusion 3 9 provided at the lower portion of the swinging portion 14 of the trigger member 15. Is exerting a biasing force.

The magazine 3 3 has a bullet outlet 3 3 a force at the tip of the magazine 3 3 as shown in FIG. 8 and is provided obliquely upward toward the bullet feed path 4 1 A on the side. 3 A wall 3 of the magazine 3 3 is formed with a notch 4 2 toward the side, where bullet feed from the bullet outlet 3 3 a to the bullet feed path 4 1 A The guiding member 4 3 for guiding is equipped so as to be able to appear and retract (see Fig. 4 and Fig. 7). This guide member 4 3 also serves as a stopper to prevent the bullet 3 2 remaining in the bullet feed path 4 1 from falling out when the magazine 3 3 is removed from the gun body 11 1. In addition, the bullet outlet 3 3 a connected to the bullet feed path 4 1 A is provided so as to be able to enter and exit from the side. Therefore, it can be said that the guide member 4 3 is located at the boundary between the magazine 3 3 and the bullet feed path 4 1 A, and at that position, the bullet 3 2 can be fed sideways to the bullet feed path 4 1 A obliquely above. As shown in FIG.

As shown in Fig. 1, Fig. 2 and Fig. 3, the example bullet feed path 4 1 A is located at the lower part of the loading part 2 8 a and on the left side. The built-in part 4 1 B of the trigger member 1 5 is a lower part of the loaded part 2 8 a, and 4 1 A only 4

. Therefore, the simulated gun according to the present invention has a loading part 2 8a located at the rear end of the barrel 2 9 where the bullet 3 2 is fired, and a bullet 3 2 located behind the loading part 2 8a. A piston device 22 for injecting compressed air, and a bullet feed which is arranged on the left side and the lower side of the barrel or piston device, and supplies bullets from the lower side to the loading unit 28a. A path 41A is provided on the lower side and the right side of the barrel or piston device, and includes a trigger member etc. that can be engaged and disengaged from the lower side of the piston device 22. It will be.

Figures 7 and 8 show the details of the magazine 3 3, magazine storage 3 4 and bullet feed path 4 1 A. The guide member 4 3 is rotatably supported by a support shaft 4 3 a in the interior of the magazine storage portion 3 4, and is urged by a spring 44 in the direction of the bullet feed path 4 1 A. On the other hand, immediately before the bullet outlet 3 3 a of the magazine 3 3, a catch 3 3 b is formed to lightly receive the bullet 3 2 pushed out from the inside of the magazine.

The simulated gun to which the side bullet feeding device 10 according to the present invention configured as described above is applied operates as shown in FIG. (1) in Fig. 9 shows that the bullet 3 1 has a bullet feed path 4 1 A and a bullet 3 2 in the loading part 2 8 a in the gun body 1 1, and a bullet with the guide member 4 3 as a stopper. 3 2 is stopped, and magazine 3 3 is being inserted there. When the magazine 3 3 is completely inserted, the guiding member 4 3 is pushed by the bullet 3 2 pushed out by the urging force of the elastic body 3 6 and rotates against the urging force of the spring 4 4. 3 2 comes off the “hook” and is pushed out from the bullet outlet 3 3 a to the bullet feed path 4 1 A using the guide member 4 3 as a guide obliquely upward (② in Fig. 9). Even if the bullet 3 2 does not accumulate as described above, the guide member 4 3 is pushed open by the bullet 3 2 pushed out by the urging force of the internal elastic body 3 6 when the magazine 3 3 is mounted, and the bullet feed The testicle 3 2 is filled from the path 4 1 A to the loading part 2 8 a. In such a bullet-filled state, by pulling the trigger 12, the piston device 21 can be operated and the bullet 3 2 can be fired.

When the magazine 3 3 is removed from the gun body 1 1, the bullet 3 2 is hooked on the hook 3 3 b inside the magazine, while the elastic body 3 6 , _π _{Λ η η} Nori Li | 5 4 3 is 4 4, “4 4” is going to return to 4: 2 (③ in Fig. 9) 4 3 is the bullet feed path 4 1 The final bullet 3 2 in the cage will be pressed down, so that only the magazine 3 3 can be removed without spilling the bullet 3 2 (see Fig. 9). ④) In addition, when the bullet 3 2 is exhausted, the elastic member 3 6 in the magazine 3 3 does not receive the urging force, so the guide member 4 3 is notched back by the spring 4 4 4 2 Let's try ((5) in Figure 9). Therefore, the final bullet 3 2 is pressed by the guide member 4 3, and the magazine 3 3 can be removed without spilling the bullet 3 2 (6 in FIG. 9).

The bullet 3 2 is loaded into the loading part 2 8 a when the bullet inlet 28 b is opened by the advancement of the barrel 29. When bullet 3 2 remains in bullet feed path 4 1 A, it may be fired by a trigger operation, but only if it is placed in bullet section 2 8 a. In a state where the extrusion force due to the elastic body 36 in the magazine is not received, the testicle 3 2 is not loaded into the loading part 2 8 a, so even if the bullet 3 2 remains in the bullet feed path 4 1 A It ’s never fired. In addition, when the magazine 3 3 is removed from the gun body 11, the engagement between the engagement portion 2 7 and the engagement counterpart portion 17 using the urging force of the elastic body 36 in the magazine is not established. Therefore, even if the trigger 1 2 is operated, the piston device 2 2 does not operate, and the bullet 3 2 is not fired. Since the present invention is constructed and operates as described above, the simulated gun has a configuration in which the bullet feed path and the other components provided in the gun body are arranged in parallel. And can be modeled. Further, according to the present invention, it is possible to provide a side feed device for a simulated gun that also has a function capable of preventing bullets from spilling from the gun when the magazine is replaced. '' Industrial applicability

As described above, the side feed device in the simulated gun according to the present invention relates to the simulated gun, but among the simulated guns, the manual gun and the electric gun are also used. I can do it.
