[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to an ammunition storage device for machine guns, etc., and more specifically, an ammunition storage device in which a plurality of belts formed by connecting a large number of ammunition with belt links are suspended in multiple rows in a meandering manner. It is related to the device.

0002

[Prior Art] Conventionally, in machine guns, etc., it has been desired to increase the number of ammunition stored in the ammunition storage device in order to improve the ability to continue fighting. Various ammunition storage devices have been proposed. For example, an ammunition storage device disclosed in Japanese Utility Model Application Publication No. 63-104898 includes a rectangular parallelepiped-shaped magazine having a bullet feeding port at the top of one end, and a plurality of support shafts from which bandoliers are suspended from both side walls of the magazine. A rotation angle regulating stopper and an ammunition stopper are installed on these support shafts to prevent the bandolier from slipping off, and the support shaft of the bandolier after sending the bullets is It is designed to move to the lower side of the bullet delivery port.

[0003] Also, an ammunition storage device 4 shown in FIGS.
0 is the belt belt 4 of the machine gun 42 mounted on the machine gun car 41
The bullet belt 43 is stored in a cylindrical magazine 45 having a bullet feeding port 44 at the top of one end, and the magazine 45 is divided into a plurality of small rooms 47 by partition walls 46, in which the belt 43 is inserted in a meandering manner. When sending bullets, use the small room 4 on the sending port side.
The bullets are sequentially unloaded from 7 and sent along guide rollers 48. Note that 49 is a turret.

0004

[Problem to be solved by the invention] However, in 1983,
- The device disclosed in Publication No. 104898 attaches one end of the bullet belt carried in from the bullet feeding port removably to the other end of the magazine during bullet feeding, and then pushes the bullet belt sequentially from the support shaft on the other end side. Because the bullets are stored in a meandering manner, it is necessary to feed bullets while changing the working position, making the bullet feeding process complicated and time consuming. When sending bullets, the support shafts of the bullet belts that have finished sending bullets are sequentially moved toward the bullet feeding port, and the belts suspended from the support shafts at the other end start feeding from a position further from the bullet feeding port. As a result, the bullets are sent while contacting the support shaft that is brought to the side of the bullet sending port. Further, since the support shaft is provided with an ammunition stopper, the bullets are fed while contacting the ammunition stopper. Therefore, the bullet sending resistance increases,
A large load will be applied to the means for driving the bandolier.

[0005] Furthermore, in the case of those shown in FIGS. 14 to 16, the bullet belt 43 is hung and stored in each small chamber 47 in a meandering manner during bullet feeding, so the bullet feeding operation is complicated and takes a long time. . Further, when the bullet is sent, the bullet belt 43 stored in the small room 47 on the other end side is sent while contacting a large number of partition walls 46 and guide rollers 48, so a large load is placed on the means for driving the bullet belt 43. will come into play.

As described above, the conventional ammunition storage device has the problem that the bullet feeding operation is complicated and takes a long time, and it is difficult to carry out the bullet feeding operation smoothly.

The present invention has been made in view of the above-mentioned conventional situation, and an object of the present invention is to provide an ammunition storage device that can easily and quickly carry out bullet feeding operations and can smoothly carry out bullet feeding operations. There is a particular thing.

[0008]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides an ammunition storage device in which a plurality of rows of bandoliers are suspended in a meandering manner in a magazine having a bullet feeding port at the upper part of one end. , a storage chain in which each end of a plurality of stay pins for hanging bandoliers is connected by a pair of stretchable and flexible chains, and the stay pins are connected to guide rails formed on both side walls of the magazine. It is mounted so that it can be moved horizontally, and a chain storage chamber is formed below the bullet feed port of the magazine in which the storage chain is folded horizontally and stored.
The bullet feeding regulating means that comes into contact with the bullet feeding port side of the bullet belt suspended from the stay pin of the storage chain and restricting movement toward the bullet feeding port side is moved upward by the bullet belt being fed to release the restriction. It is set up in

A bullet feeding guide plate is provided above the chain storage chamber so as to be able to swing vertically and cover the top of the chain storage chamber during bullet feeding. Preferably, it is connected to a storage room. In addition, the storage chain is equipped with a position regulating member that prevents the ammunition in the bandolier suspended from the stay pins from moving in the axial direction, and a position regulating member that engages between the ammunition in the bandolier suspended from the stay pin to prevent it from falling. Preferably, the means is rotatable about the central axis of the stay pin.

0010

[Operation] According to the present invention, the storage chain has the first and second storage chains.
Since the chain is stretchable and flexible,
When the bullet feeding is completed, the bullets are folded horizontally and stored in the chain storage chamber. At the time of bullet feeding, the stay pin of the storage chain is pulled out from the chain storage chamber, the bandolier carried in from the bullet feed port is engaged with this stay pin, and the stay pin is pushed so as to engage with the bullet feed regulating means. As a result, the next stay pin is pulled out from the chain storage chamber and moved to the bullet feeding regulating means in the same manner as the previous stay pin. Thereafter, repeat the same operation to hang the bandolier from each stay pin in a meandering manner. At that time, the bullet belt is engaged with each stay pin below the bullet feed port and suspended, and by being pushed up to the bullet feed regulating means, the interval between each stay pin is contracted, and the bullet belt is suspended so that it is in contact with each other. . Furthermore, since the chain storage chamber is empty after the last stay pin is pulled out, the chain storage chamber is also stored in a meandering manner.

At the time of bullet feeding, the bullet belt stored in the chain storage chamber is fed, and then the bullet belt of the stay pin that is pulled out last is fed. During the feeding of this bullet belt, the previous stay pin is held by the bullet feeding regulating means, but as the bullet feeding progresses, the bandolier becomes tensed and pushes up the bullet feeding regulating means, causing the above-mentioned one to stop. The front stay pin moves to the side of the bullet feed port. Then, the bullet belt suspended from the previous stay pin is engaged with and held by the bullet feed regulating means, and the last stay pin pulled out is stored in the chain storage chamber. Thereafter, the stay pin is similarly moved to the bullet sending port side, and the stay pin that has finished sending bullets is stored in the chain storage chamber. At this time, the bandolier of each stay pin is carried out from below the bullet feed port, and since the first and second chains are flexible, the storage chains are folded horizontally one after another and placed in the chain storage chamber. It will be stored.

If the magazine is equipped with a bullet feeding guide plate, by covering the upper part of the chain storage chamber when feeding bullets, the loaded bullet belt will not enter the chain storage chamber and will be guided along the pulled out stay pin. Guide them to descend smoothly.

[0013] When the end of the guide rail on the bullet feeding port side is inclined downward, the distance between the stay pin held by the bullet feeding regulating means and the stay pin closest to the chain storage chamber is wide, so that the bullet feeding is restricted. Bullets are fed and sent so as not to interfere with the belt held by the means.

When the stay pin is provided with a position regulating member, even if the magazine is cylindrical, the head of the ammunition moves so as not to contact the side wall of the magazine during feeding and feeding.

When the stay pin is provided with fall prevention means, when the bandolier slips off the stay pin due to vibration, rotational movement, etc., the fall prevention means rotates and presses the ammunition in the bandolier against the ceiling of the magazine. This keeps the bandolier in place

Note that the bullet feeding guide plate 32 may be swingably provided above the chain storage chamber 7 so as to cover the upper side of the chain storage chamber 7 until just before the bullet feeding is completed, and then retreat.

This embodiment is configured as described above,
The effect will be explained next.

At the time of bullet feeding, as shown in FIG. 11, the storage chain 10 is folded horizontally and stored in the chain storage chamber 7, and the first stay pin 12 protrudes from the chain storage chamber 7. A bullet feeding guide plate 32 is attached above the bullet feeding guide plate 32. The bullet belt 11 carried in from the bullet feed port 4 is guided by the bullet feed guide plate 32 and descends along the first stay pin 12. When the tip of the bandolier 11 reaches the bottom 3d of the magazine, the loading is interrupted, and the first stay pin 12 is pushed up to the bullet feeding regulating lever 29 to resume loading. As a result, the bandolier 1 is attached to the first stay pin 12.
1 is suspended and held by a bullet feeding regulating lever 29 so as not to retreat. On the other hand, the second stay pin 12 is pulled out from the chain storage chamber 7, and the belt 11 to be carried in descends along this stay pin 12. and,
When the bullet belt 11 reaches the bottom 3d of the magazine, the loading is interrupted and the second stay pin 12 is pushed up to the bullet feed restriction lever 29. As a result, as shown in FIG. 1, the first stay pin 12 is moved to the other end, and the third stay pin 12 is moved to the other end.
is pulled out from the chain storage chamber 7. Thereafter, the bullet belt 11 is suspended from each stay pin 12 in the same manner, but when the last stay pin 12 is pulled out, the bullet feed guide plate 3
2 is removed and, as shown in FIG. 12, the bandolier 11 is also carried into the chain storage chamber 7 after being suspended from the last stay pin 12.

The bullet feeding operation is carried out as described above, but since the stay pin 12 of the storage chain is connected by the first chain 13 and the second chain 14 which are extendable and flexible, the bullet belt 11 is connected to the stay pin 12. After engaging the stay pin 12, the next stay pin 12 can be pulled out from the chain storage chamber 7 by pushing it up to the bullet feeding restriction lever 29. The chain storage chamber sides of the guide rails 8 and 9 are inclined downward, and the stay pin 12 from which the bandolier 11 is hung is held by the bullet feed regulation lever 29, so that the stay pin 12 and the stay pin 12 closest to the chain storage chamber 7 are Since the distance between the chain storage chamber 7 and the bullet feeding guide plate 32 is increased, the bullet belt 11 to be carried in can be smoothly engaged with the stay pin 12 closest to the chain storage chamber 7. Therefore, bullet feeding work can be performed easily and in a short time. On the other hand, since the distance between the stay pins 12 is reduced, the bandolier 11 pushed up to the bullet feeding regulation lever 29 is suspended in a state in which they are in contact with each other. Further, the bandolier 11 can be stored in the space between the bullet feeding regulation lever 29 and the chain storage chamber 7 and in the chain storage chamber 7. Therefore, the number of stored ammunition can be significantly increased.

When sending bullets, as shown in FIG. 12, the belt 11
are stored in multiple rows suspended in a meandering pattern, and after pulling up the bandolier 11 in the chain storage chamber 7, the last stay pin 1 is
2. Pull up the bandolier 11. This portion is pulled up so as not to interfere with the bullet belt 11 of the adjacent stay pin 12, which is held by the bullet feed regulation lever 29 so as not to move toward the bullet feed port until immediately before the end of bullet feed. At the end of the above bullet feeding, as shown in FIG.
becomes nervous and pushes up the bullet feed restriction lever 29 to release the restriction. As a result, the adjacent stay pin 12 moves to the bullet feeding port side, that is, to the immediate vicinity of the chain storage chamber 7, and the bandolier 11 of this stay pin 12 is pulled up. Thereafter, in the same manner, every time the bullet belt 11 suspended from the nearest stay pin 12 of the chain storage chamber 7 finishes transmitting, the bullet feed regulation lever 29 is activated.
is released, the adjacent stay pin 12 is moved to the immediate vicinity of the chain storage chamber 7, and the bullet is sent. On the other hand, the stay pin 12 that has finished sending bullets moves to the chain storage chamber 7, but since the storage chain 10 has elasticity and flexibility, it is folded horizontally as shown in FIG. It will be stored.

The bullet feeding operation is performed as described above, but the bullet feeding is always started in the vicinity of the chain storage chamber 7, and the stay pin 12 held by the bullet feeding regulation lever 29 and the stay pin closest to the chain storage chamber 7 are 12, and since the position regulating member 27 is provided on the stay pin 12, the bullet feeding operation can be carried out smoothly.

[0026] During the period from the start of bullet feeding to the completion of bullet feeding,
The bandolier 11 is suspended from the stay pin 12 of the storage chain, but since the stay pin 12 is provided with a fall prevention pin 28, when the bandolier 11 tries to slip down due to vibration, rotational movement, etc. As shown in FIG. 8, the fall prevention pin 28 rotates together with the bandolier 11 to press and hold the ammunition 11a against the ceiling 3a of the magazine. Therefore, when feeding bullets,
Each time the bandolier 11 is suspended from the stay pin 12, the bandolier 11 is pushed up to the bullet feed regulation lever 29, thereby allowing the bandolier 11 to be hung in an orderly meandering manner. Further, after the bullet feeding is completed, since the bandolier 11 is suspended so as not to slip down, each stay pin 12 can be moved to the vicinity of the chain storage chamber 7 and the bullet can be fed.

The present invention is not limited to this embodiment; for example, the magazine may have a rectangular parallelepiped shape. It is sufficient that the fall prevention pin engages between the ammunition of the bandolier and rotates as the ammunition moves, and if the stay pin is fixed, it may be rotatably provided on the stay pin. The storage chain may be such that the first staple pin is slightly recessed into the chain storage chamber.

[0028]

According to the present invention, when feeding bullets, the bandolier is engaged with the stay pin of the storage chain in the vicinity of the chain storage chamber, and by pushing this to the bullet feeding regulation lever, the bandolier is arranged in multiple meandering rows. Since it can be suspended from the ground, bullet feeding work can be done in a fixed position. Further, since the bullet belt suspended from the stay pin is held so as not to retreat by the bullet feeding regulating means, the bullet belt to be carried in can be smoothly engaged with the stay pin pulled out from the chain storage chamber. Therefore, it has become possible to perform bullet feeding work easily and in a short time.

At the time of bullet feeding, the stay pin of the bullet belt to be fed moves to the immediate vicinity of the chain storage chamber, and can be pulled up almost from below the bullet feeding port. Since the adjacent bullet belts are held by the bullet feeding regulating means, the bullet belts to be fed do not interfere with the adjacent bullet belts. In addition, the tension of the bullet belt used to push up and release the bullet sending restriction means,
No large resistance is generated. Therefore, a large load is not applied to the means for driving the belt, and the bullet feeding operation can be carried out smoothly.

[0030] By providing a bullet feeding guide plate in the magazine, it is possible to guide the loaded bullet belt and allow it to descend smoothly along the stay pin, making it possible to carry out bullet feeding work more easily and in a shorter time. Ta.

By slanting the end of the guide rail on the bullet feeding port side downward, the distance between the stay pin held by the bullet feed regulating means and the stay pin closest to the chain storage chamber is widened, so that it is difficult to carry in or take out the bullet. The bullet belt can be carried in and out without interfering with the bullet belt held by the bullet feeding regulating means, making it possible to carry out bullet feeding and bullet feeding operations more efficiently. .

By providing a position regulating member on the stay pin, even if the magazine is cylindrical, it is possible to move the head of the ammunition so that it does not come into contact with the side wall of the magazine during bullet feeding and feeding, and the bullet feeding operation is improved. And it has become possible to carry out bullet feeding work more efficiently.

[0033] By providing a fall prevention pin on the stay pin, it is possible to hold the bandolier without it slipping off due to vibration, rotational movement, etc., and it has become possible to perform bullet feeding and bullet feeding operations more efficiently. .
