Description

Drum magazines used for rifle with interchangeable barrels}

The present invention relates to a drum magazine used in a barrel replaceable rifle, and more particularly, in a rifle in which a barrel of a rifle is replaced and a drum magazine filled with bullets corresponding to the replaced barrel is used by combining the rifle with a drum magazine. It relates to a drum magazine used in a barrel replaceable rifle that can prevent a phenomenon in which defective bullet feeding occurs due to an inaccurate combination of

In general, in a rifle, a hammer strikes a ball connected to a bolt by pulling a trigger, and when the ball strikes a detonator, which is the tail end of a bullet bitten by a bolt bundle, the explosive force of gunpowder exploding causes the warhead to explode in the gun body. It is fired through the barrel connected to the front, and the bolt bundle retreats due to the gas pressure generated during the explosion, dragging the cartridge case out and discharging it to the outside.

Then, the bolt bundle advances again to bite the bullet supplied from the magazine into the chamber, and the hammer connected to the bolt is positioned at the position before striking, so that the hammering action is performed again by the next trigger firing action.

These rifles are basic personal portable firearms used in the military, and are divided into manual loading and automatic loading (automatic/semi-automatic) depending on the firing mechanism. Today, almost all armed forces of countries are equipped with automatic rifles.

Most of the existing rifles use an integral chamber, which is to withstand the tremendous pressure when the gunpowder inside the bullet explodes. For this reason, the chamber is made of an integral type, and the front is connected to the barrel from which the bullet is fired, and the rear is provided with a space large enough to insert the bullet.

In addition, the ammunition used in these rifles has various specifications, and among them, the AR-15 rifle mainly used in the West can be an example as a representative rifle using 5.56mm ammunition, and a representative rifle using 7.62mm ammunition. As an example, the AK-47 rifle mainly used in Eastern Europe can be used.

And the types of magazines used in these rifles include box magazines, cassette magazines, drum magazines, disc magazines, rotary magazines, spiral magazines, etc. Among these magazines, the drum magazine used in the AK-47 rifle has 75 It is a magazine in which bullets are sequentially supplied to the chamber of an AK-47 rifle through rotation by a spring in a state where bullets are accommodated.

On the other hand, in the bullets used in rifles, the 5.56mm bullet has a destructive power of 1,775 J, and the weight of the warhead is approximately 3.6g, so it has excellent accuracy with little recoil, and the 7.62mm bullet has a destructive force of 3,352 J, , the weight of the warhead is approximately 8 g, and the destructive power is excellent, but the accuracy is relatively low due to the large recoil.

Therefore, in consideration of the characteristics of these bullets, rifles are being improved and used so that bullets of different specifications can be used in one rifle.

For example, if you want to use 7.62mm rounds in an AR-15 rifle that has a barrel that uses 5.56mm rounds by default, remove the 5.56mm barrel from the AR-15 and install the 7.62mm round barrel. By replacing the AR-15 with the barrel for 5.56mm bullets removed, the AR-15 rifle can be changed into a rifle that uses 7.62mm bullets.

On the other hand, a 7.62mm bullet is loaded into the rotating member 20 (see FIG. 1(b)) that rotates together with the actuator 21 as a magazine fitting of an AR-15 rifle whose barrel has been changed so that a 7.62mm bullet can be used. When the insertion part 11 (see FIG. 1 (a)) of the filled drum magazine 10 for the AK-47 rifle is used in combination, the magazine of the AK-47 rifle compared to the length of the magazine insertion part of the AR-15 rifle Since the length of the fitting part is short, the insertion part (11) of the drum magazine for the AK-47 rifle cannot be coupled to the magazine fitting part of the AR-15 rifle, so the bullets of the drum magazine for the AK-47 rifle cannot be inserted into the AR-15 rifle. There was a problem that it could not be moved to the chamber.

In addition, throughout the specification, when a certain component is said to "include", it means that it may further include other components without excluding other components unless otherwise stated.

Hereinafter, the configuration of the present invention will be described in more detail with reference to the illustrated drawings.

First, prior to the detailed description of the drum magazine, the AR-15 rifle using such a drum magazine is an improved rifle that can use different types of bullets through replacement of barrels.

These AR-15 rifles can be used by selecting either a barrel that can use 5.56mm bullets or a barrel that can use 7.62mm bullets, and combining them with the AR-15 rifle. The bolt body corresponding to the available ammunition can be exchanged together.

The present invention is improved so that the drum magazine for the AK-47 rifle can be coupled to the magazine fitting of the AR-15 rifle replaced with a barrel in which 7.62mm bullets are used.

As shown in FIGS. 2 and 3, in this drum magazine, a rotating member 300 for guiding bullets while being elastically rotated through a spring is installed inside a cylindrical body 100 with an open rear surface, and such a rotating member 300 The bullet whose movement is guided by is moved to the chamber of the AR-15 rifle through the inside of the insertion part 110 provided on one side of the outer circumference of the cylindrical body 100 and coupled to the magazine fitting part of the AR-15 rifle. , The open rear surface of the cylindrical body 100 is opened and closed through the cover 200 rotatably installed on the other side of the outer circumference of the cylindrical body 100.

In addition, the bullets installed between the rotary members 300 inside the cylindrical body 100 are moved along the spiral track provided on the inner surface of the cylindrical body 100 through the rotation of the rotary member 300 according to the operation of the spring and then inserted. Guided by the guide 320 located below the part 110, it moves into the insertion part 110, and when the insertion part 110 is inserted into the magazine fitting part of the AR-15 rifle, the insertion part 110 As the upper end of the is located in the chamber of the AR-15 rifle, the bullet discharged from the upper end of the insertion part 110 moves to the chamber of the AR-15 rifle through the advancement of the bolt bundle, and the warhead is then fired according to the barrel. It is fired to the outside along the way, and the cartridge case is discharged to the outside through the cartridge case outlet.

On the other hand, compared to the magazine fitting part of the AK-47 rifle structurally, the AR-15 rifle's magazine fitting part is formed relatively long, so that the conventional drum magazine 10 used in combination with the magazine fitting part of the AK-47 rifle If the insertion part 11 is inserted into the magazine fitting part of the AR-15 rifle as it is, the upper end of the insertion part 11 is not located in the chamber of the AR-15 rifle, and bullet feeding cannot be performed.

Therefore, the present invention extends the length of the insertion part 110 installed on the upper side of the outer circumference of the cylindrical body 100 constituting the drum magazine to a length corresponding to the length of the magazine fitting part of the AR-15 rifle. When the insertion part 110 is inserted into the magazine fitting part of the AR-15 rifle, the upper end of the insertion part 110 is accurately positioned in the chamber of the AR-15 rifle, and bullet feeding is performed normally.

75 bullets are filled inside the cylindrical body 100 of the drum magazine, and looking at the process of filling the 75 bullets, first of all, through the inner entrance of the insertion part 110 from the inside of the cylindrical body 100 After the bullets of the feet are filled into the insertion part 110 in advance, the remaining 69 bullets are sequentially filled between the rotation members 300.

However, in the process of loading 6 bullets along the invisible inner passage of the insertion part 110, bullets may be filled inaccurately, which may cause poor bullet supply.

Therefore, in the present invention, in forming the insertion part 110 by extending the length of the outer circumference of the cylindrical body 100, the cutout 120 is configured so that a partial area is opened at the bottom of the rear surface of the insertion part 110. When filling six bullets through the insertion portion 110, the bullets can be accurately filled while visually checking the bullets using the cutout 120.

In addition, when the open rear surface of the cylindrical body 100 is closed by the cover 200 after all 75 bullets have been filled inside the cylindrical body 100, the cutout 120 formed in the insertion part 110 Since it needs to be closed together, a cover 210 may be provided so that the incision 120 can be closed for this purpose.

The cover 210 closing the cutout 120 may be configured separately to be detachable from the cutout 120 while having a shape corresponding to the shape of the cutout 120 in one embodiment, and in another embodiment the cover ( 210) protrudes and extends to the outer circumference of the cover 200 that closes the open rear surface of the cylindrical body 100, so that when the open rear surface of the cylindrical body 100 is closed by the cover 200, the cover 200 The extended cover 210 may be configured to simultaneously close the cutout 120 .

In addition, as shown in FIG. 2, the surface of the cover 210 may preferably further have a protrusion 211 for preventing slippage. As such, when at least one protrusion 211 for preventing slippage is provided on the surface of the cover 210 When the insertion part 110 is inserted into the magazine fitting part of the AR-15 rifle, the anti-slip protrusion 211 of the cover 210 closing the cutout 120 of the insertion part 110 is supported on the inner surface of the magazine fitting part. As it is, it serves to push the cylindrical body 100 forward where the barrel is located, and this role has the following effects.

That is, when the cylindrical body 100 is filled with 75 bullets, the cylindrical body 100 sags toward the trigger due to the weight of the bullet in the state where the insertion portion 110 of the cylindrical body 100 is coupled to the magazine fitting part. This may occur, and when sagging occurs in this way, the upper end of the insertion portion 110 may be displaced from the normal position of the chamber, resulting in poor supply of bullets.

However, as described above, as the anti-slip protrusion 211 provided on the cover 210 pushes the cylindrical body 100 toward the barrel, the phenomenon in which the cylindrical body 100 sags toward the trigger due to the weight of the bullet is prevented in advance. Therefore, the cause of poor coal feeding due to sagging of the cylindrical body 100 can be eliminated.

On the other hand, the actuator 310 is installed in the rotary member 300 installed inside the cylindrical body 100, and as illustrated in FIGS. Among the bullets sequentially moved toward the chamber, the last bullet remaining in the cylindrical body 100 is moved to the upper end of the insertion portion 110 and accurately moved to the chamber of the AR-15 rifle.

Therefore, with the length of the conventional actuator 21 used in the drum magazine 10 for the AK-47 rifle, the bullet cannot be moved to the upper end of the extended insertion portion 110 according to the present invention, so that the last bullet is fed It doesn't work.

Accordingly, the present invention extends the length of the actuator 310 in order to move the last shot to the upper end of the lengthened insertion portion 110, and this actuator 310 does not simply extend the length, as illustrated in FIG. As it is moved along a curved path forming an almost right angle under the guidance of the guide 320 when moving into the insertion part 110 as described above, the actuator 310 accurately enters and ascends into the insertion part 110. to have an appropriate shape.

That is, although not illustrated in the drawing, the actuator may be extended to a predetermined length in a state in which the lower end is hinged to the rotary member 300 in the first embodiment, but configured in a straight line shape. By being made of a synthetic resin material with flexibility that can be bent and then returned to its original state when the external force is removed, the operating tool touches the guide 320 and is elastically bent while accurately entering and rising into the insertion part 110 It can be.

Here, a plurality of bending guide grooves may be formed at regular intervals on the inner surface of the actuator to assist in the smooth bending of the actuator.

And, although not illustrated in the drawings, the actuator is extended to a predetermined length in a state in which the lower end is hinged to the rotary member 300 in the second embodiment, but is configured to have a curved shape bent with a predetermined curvature from the upper end to the lower end, thereby operating The sphere may naturally enter and ascend into the insertion part 110 under the guidance of the guide 320 .

In addition, as illustrated in FIG. 10, the actuator 310 extends to a predetermined length in a state in which the lower end is hinged to the rotary member 300 in the third embodiment, and the predetermined length from the upper end to the straight portion 311 It is configured, and from such a straight portion 311 to the lower end may be composed of a curved portion 312 of a constant curvature.

Here, the ratio of the straight portion 311 and the curved portion 312 may preferably be configured at a ratio of 3:2, and this ratio does not need to be limited to the ratio of 3:2, depending on the length of the insertion portion 110. Correspondingly, it can be composed of various proportions.

In addition, the curvature of the curved portion 312 may be configured to be approximately 24 mm to 25 mm, and when the curvature of the curved portion 312 is less than 24 mm or greater than 25 mm, when the operating tool 310 rises, the insertion portion 110 ) It is caught on the inner wall of the interior, making it difficult to move, making it impossible to accurately feed the coal.

In addition, as illustrated in FIG. 11, the actuator 310a is extended to a predetermined length in a state in which the lower end is hinged to the rotary member 300 in the fourth embodiment, and the predetermined length at the upper end is a straight portion 311a It is composed of a first curved part 312a having one curvature at a certain length from the straight part 311a, and a second curved part having another curvature from the first curved part 312a to the lower end. (312b).

Here, the ratio of the straight portion 311a, the first curved portion 312a, and the second curved portion 312b may be preferably 1:1.7:1, and this ratio is 1:1.7:1. It may be configured in various ratios corresponding to the length of the insertion part 110 without being limited to the ratio.

In addition, the curvature of the first curved portion 312a may be approximately 103 mm to 105 mm, and when the curvature of the first curved portion 312a is less than 103 mm or greater than 105 mm, when the actuator 310a rises. As it is caught on the inner wall of the insertion part 110 and it is difficult to move, the coal feeding cannot be performed accurately.

And, the curvature of the second curved portion 312b may be composed of approximately 19 mm to 20 mm, and when the curvature of the second curved portion 312 b is less than 19 mm or greater than 20 mm, the actuator 312 a is inserted when it rises. As it is caught on the inner wall of the unit 110 and it is difficult to move, the coal feeding cannot be performed accurately.

In addition, although not illustrated in the drawings, the actuator is hinged to each other in a state where the straight part 311 and the curved part 312 are individually configured instead of one body in the third embodiment described above as the fifth embodiment, but torsion A spring is installed together so that the angle of the connection part between the straight part 311 and the curved part 312 can be elastically changed by the torsion spring, so that the actuator is guided by the guide 320 and the insertion part 110 can accurately and effectively enter and ascend into the interior of the

In addition, although not illustrated in the drawings, the actuator is the sixth embodiment, and in the fourth embodiment described above, the straight portion 311a, the first curved portion 312a, and the second curved portion 312b are not a single body, but individually, respectively. In the configured state, they are hinged to each other, and each connecting portion is hinged together with the first torsion spring and the second torsion spring, so that the straight portion 311a, the first curved portion 312a, and the second curved portion 312b Since the angle of the connecting portion can be elastically changed by the first and second torsion springs, the actuator can accurately and effectively enter and ascend into the insertion part 110 under the guidance of the guide 320 .

In addition, as illustrated in FIG. 12, the actuator 310b is extended in length corresponding to the lengthened length of the insertion part 110 in order to move the last bullet to the upper end of the insertion part 110 as in the seventh embodiment. It can be configured by installing a virtual bullet 330 on the upper end 313b while having a short length like the actuator 21 used in the conventional drum magazine 10 without the need to change the shape or change the shape.

That is, the actuator 310b has a length corresponding to the length of the insertion portion 110, which has been lengthened while the virtual bullet 300 is included, and the actuator 310b is guided by the guide 320 to form an almost right angle and bend When moving into the insertion part 110 through the losing path, the last bullet can be accurately moved to the top of the insertion part 110 by the virtual bullet 330 installed on the upper end 313b of the operating tool 310b. .

Here, the virtual coal 330 may preferably be configured such that a plurality of them are sequentially combined to form a plurality of layers. For example, the first virtual coal 330a, the second virtual coal 330b, and the third virtual coal ( 330c) and a fourth virtual bullet 330d.

The number of virtual bullets 330 may be various in consideration of the length of the insertion part 110, the length of the actuator 310b, the diameter of the virtual bullet 300, and the like.

On the other hand, when the virtual bullets 330 composed of a plurality of them are guided by the guide 320 and move along a path that is bent at an almost right angle, the connected shape may change in response to an external force according to the surrounding environment. For this purpose, the first virtual bullet 330a, the second virtual bullet 330b, the third virtual bullet 330c, and the fourth virtual bullet 340d are coupled to each other through a link so as to be able to rotate in place. Depending on the external force applied by the application, the shape connected as a whole may be configured to form a curved shape.

That is, the first virtual coal 330a, the second virtual coal 330b, the third virtual coal 330c, and the fourth virtual coal 340d are the first virtual coal 330a and the second virtual coal for freely changing curves. The bullet 330b is connected through the first link 331a, the third virtual bullet 330c and the fourth virtual bullet 340d are connected by the second link 331b, and connected by the first link 331a. In the case of the first virtual coal 330a and the second virtual coal 330b, they are rotatable without being separated from the third virtual coal 330c and the fourth virtual coal 340d connected by the second link 331b. The second virtual coal 330b and the third virtual coal 330c may be connected through a third link 331c.

Therefore, when the operating tool 310b and the virtual bullet 330 are guided by the guide 320 and moved into the insertion part 110 having a curved path forming an almost right angle, the virtual bullet 330 is inserted into the insertion part ( 110) when an external force is applied to the inner wall, the first virtual coal 330a, the second virtual coal 330b, the third virtual coal 330c, and the fourth virtual coal 330d are individually rotated by the applied external force. As one curved shape necessary for movement is formed, the last bullet can be smoothly moved to the upper end of the insertion part 110.

On the other hand, as the first virtual bullet 330a is coupled to the upper end 313b of the actuator 310b, it may be simply fixed without considering rotation, but may also be rotatably coupled through a hinge or link. .

In addition, by connecting the first virtual bullet 330a to the upper end 313b of the operating tool 310b in a detachable manner in an assembled form, the entire virtual bullet 330 is detached from the upper end 313b as necessary, and the virtual bullet ( 330) can facilitate maintenance such as inspection or replacement.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the description. Therefore, the scope of the described content does not need to be limited to the described embodiments, and should be defined by not only the claims described later, but also those equivalent to these claims.
