Description

The present invention relates to a rapid-fire gun capable of implementing multiple revolving magazines.

A revolver-type pistol can continuously fire about six bullets from a rotating magazine.
Automatic pistols, in contrast to revolver pistols, store the magazine in the barrel and can hold more bullets than the revolver pistol's revolving magazine. However, with automatic pistols, if a bullet fails to fire, the bullet remains in the chamber, and the next bullet cannot be loaded into the chamber, making continuous fire impossible. In this regard, revolver-type pistols are highly reliable because they can fire continuously even if they do not fire.

As for such a revolver-type pistol, one described in Patent Document 1 is known.
The loading cylinder replacement mechanism for a rotary pistol described in this Patent Document 1 replaces a loading cylinder, which conventionally could not be easily replaced, by simply pushing out a used loading cylinder with a new loading cylinder. The cylinder can be easily attached to the frame.

The operation and usage of the rapid-fire gun 10 according to the embodiment of the present invention configured as described above will be described with reference to the drawings.
First, a bullet is loaded into the chamber R1 of the rotary magazine R shown in FIG. 2(B). Then, the magazine part 30 removed from the barrel part 20 is loaded with a rotary magazine R filled with bullets in the chamber R1. Then, a magazine section 30 loaded with a predetermined number of rotary magazines R is attached to the barrel section 20. - 特許庁This completes the loading of the ammunition.

When the loading of the bullet is completed, by pulling the trigger 41, the bullet is discharged from the chamber R1 and can be discharged from the barrel portion 20. - 特許庁Even if the bullet misfires, pulling the trigger 41 rotates the rotary magazine R by one shot, and the chamber R1 of the next bullet is positioned in front of the firing pin. Therefore, the rapid-fire gun 10 according to the present embodiment has high reliability because it can fire continuously even if it fails to fire, which is an advantage of the revolver-type pistol.

Assume that all the bullets loaded in the chamber R1 of the rotary magazine R are fired.
The user advances the handle portion 511 of the loading lever 51 toward the distal end side of the barrel portion 20 .
By doing so, the connecting portion 513 moves to the tip side of the barrel portion 20 by moving the operating shaft 512 together with the handle portion 511 .
The supporting shaft 532 is pulled out from the bearing hole R2 of the rotary magazine R by moving the leg 531 along with the movement of the connecting portion 513 .

Further, by moving the connecting portion 513 toward the distal end side of the barrel portion 20, the transmission shaft 524 of the rotation mechanism portion 52 moves toward the distal end side.
As the transmission shaft 524 moves, the blade portion 522a is inserted into the thread groove 521a of the cylindrical portion 521 and presses the thread groove 521a. Further, the blade portion 522b presses the thread groove 521b in a state of being inserted into the thread groove 521b of the cylindrical portion 521. As shown in FIG.
Due to this pressing, the pair of blades 522a and 522b press against the screw grooves 521a and 521b and move to the tip, thereby rotating the cylindrical portion 521 by 90 degrees.

The rotation of the cylinder portion 521 causes the gear portion 541 of the magazine exchange mechanism portion 54 to rotate.
The rotation of the gear portion 541 causes the rotation shaft 542 to rotate. As the rotating shaft 542 rotates, the loading plate 543 rotates 90 degrees.
By rotating the loading plate 543 by 90 degrees, the loading plate 543 located at the bottom of the loading chamber 21 pushes out the rotary magazine R in the loading chamber 21, so that the rotary magazine R is ejected from the barrel portion 20. .
In addition, the rotary magazine R located on the loading chamber 21 side of the magazine section 30 is replaced by the loading plate 543 located on the side of the magazine section 30, and the loading plate 543 ejecting the rotary magazine R that was in the loading chamber 21. The rotary magazine R filled with bullets is sent to the loading chamber 21 by pushing up the loading plate 543 at a position shifted by 90 degrees.

Then, the handle portion 511 of the loading lever is retracted toward the base end side of the barrel portion 20 . By doing so, the connecting portion 513 moves to the base end side of the barrel portion 20 by moving the operating shaft 512 together with the handle portion 511 .
As the leg portion 531 moves with the movement of the connecting portion 513, the supporting shaft 532 is inserted into the bearing hole R2 of the rotary magazine R, and the tip portion 532a of the supporting shaft 532 fits into the fitting hole of the loading chamber 21. is inserted into Therefore, the rotary magazine R is supported within the loading chamber 21 by the supporting shaft 532 .

Further, when the transmission shaft 524 moves toward the base end of the barrel portion 20, the spring portion 523 that imparts an elastic force in the direction to open the pair of blade portions 522a and 522b is contracted. , 522b are closed, the pair of blades 522a and 522b move in the cylinder 521 and return to their original positions without rotating the cylinder 521. As shown in FIG.

In this way, even though it is a revolver type handgun, the rotary magazine R filled with six bullets can be loaded one after another into the loading chamber 21, so that the replacement time of the rotary magazine can be shortened.
Therefore, the rapid-fire gun 10 not only has higher reliability than an automatic pistol, but also reduces the risk of being hit by shortening the replacement time of the rotary magazine.

Further, since the rotary magazine R can be loaded into the loading chamber 21 only by operating the loading lever 51 back and forth after all bullets in the rotary magazine R have been fired, the next rotary magazine R can be quickly prepared. .

At this time, the projection protruding from the third loading plate 543 c of the loading plate 543 fits into the groove 544 a formed in the peripheral edge of the cam portion 544 . Therefore, when the rotary magazine R is ejected from the loading chamber 21 and when the rotary magazine R is loaded into the loading chamber 21 from the magazine portion 30, the protrusion of the third loading plate 543c is in contact with the arc portion of the cam portion 544. move along. Therefore, the loading plate 543 rotates with the second loading plate 543c extending from the first loading plate 543a.
However, since the protrusion of the third loading plate 543c moves along the chord portion of the cam portion 544, the third loading plate 543c is partially accommodated in the second loading plate 543b, and the third loading plate 543c A part of the second loading plate 543b is stored in the first loading plate 543a, so that the second loading plate 543b is in a contracted state. Therefore, the loading plate 543 can be made compact.

As shown in FIG. 1, along the barrel section 20 is a magazine section 30 in which the revolving magazines R are stored in tandem. For example, some machine guns are mounted so that the magazine portion extends downward from the barrel portion. However, with such a machine gun, if you aim at a target in the lying down position, the magazine will touch the ground and become an obstacle, making it difficult to shoot in the lying down position. However, in the rapid-fire gun 10 according to the present embodiment, since the magazine portion 30 is arranged along the barrel portion 20, the magazine portion 30 does not interfere with aiming at the target in the lying down state. Able to aim and fire bullets at a target.

In automatic pistols, the magazine is stored in the barrel. Therefore, handguns that can handle large bullets are restricted due to the large size of the handle. However, revolver-type pistols can handle even large bullets by increasing the size of the chamber of the rotary magazine R or thickening the barrel. Therefore, the rapid-fire gun 10 according to the present embodiment can also handle bullets with high destructive power.

The rapid-fire gun of the present invention can be applied to a revolver-type pistol that fires non-real bullets in addition to rapid-fire live bullets.
