銃身を使用することがただ一つの方法になっている。<Prior Art> As shown in FIG. 9, a generally known shotgun cartridge is equipped with a cartridge 2 equipped with a detonator at the center 1 of the rear end face, a gunpowder 3, a feed 11 consisting of a gas seal wad 4 and a fiber wad 5, and a shot cover. 6. After filling the cartridge 7, it is sealed with the crimb 15 by the number 8 and the opening 9 of the cartridge 2. The shot cover 6 has a shape in which a plurality of cylindrical pieces 68 are integrally attached to a disc 6B, and a slit 10 is formed between each adjacent cylindrical piece 6^ to form a notch shape. This shotgun cover 6 is provided to prevent the shotgun 7 from coming into contact with the inner surface of the barrel and attaching lead, as well as to protect the shotgun 7 from being deformed. 6
A is made to open like a flower petal, detach from shotgun 7, and fall. Invention or problem to be solved> In order to prevent bullets from being shot at long distances or to impact the hit object, it is necessary to narrow the spread of the ejected bullets and create a dense pattern. The barrel of a shotgun has a diaphragm barrel that narrows the spread of the ejected shot to increase its density, making it suitable for long-distance shooting. More than 50 years ago, a paper bag or I+I2I bag was developed as a loading method that reduces the degree of dispersion even when fired from a ten-tube barrel (improved flat barrel, skeet aperture, recessed choke, perfect round high) without relying on this aperture barrel. Attempts have been made to create a system in which shotguns stored in a bag are loaded into a cartridge, and after flying a predetermined distance after ejection, the bag ruptures, exposing the shotguns and starting dispersion. However, it could not be put to practical use because the bag would break while passing through the gun barrel, or the bag would not break at all after ejection and would fly in the form of a single bullet containing a shotgun. Therefore, even today, the only way to significantly increase the tightness of the dispersion is to use a diaphragm barrel.

ことが本発明の特徴である。Next, the operation of the first embodiment will be explained. Due to the explosive pressure of the gunpowder 3, the cartridge 20 containing a predetermined group of shotguns is moved from a stationary state to an I
It is accelerated to transonic speed, which exceeds the speed of sound, and is ejected from the muzzle within a minute time of O-3 seconds. Therefore, not only is the acceleration while passing through the gun barrel intense, but since the bullet 7 is made of a lead-based alloy, it has a large mass, and the force that resists acceleration, that is, the inertial drag, is large. The feature of the present invention is that this large inertial drag is utilized.

3 omits this. fit '5ll17 Kabun 2 2 0CZ and u' t Saku Jl (1) Contrary to the fact that the bottom disc 21 is forced to accelerate rapidly due to the explosive pressure, the opposing shotguns, for example, the shotguns 7, have the same speed due to inertia. trying to maintain. Therefore, the shot 7^ is pressed against the front surface 26 of the bottom disk 21 in a direction parallel to the axis due to the above-mentioned inertial drag, creating a deep groove 128.

2 is inflated and its outer part is brought into pressure contact with the gun cavity 13A. Also, since the defeated bullet 7D moves radially toward the axis, lIli! near the axis! Push the shotgun 7[ of the l contact strongly. In this way, the contact pressure between the lost bullets 7 increases, and the lost bullets 7 are mutually locked by strong frictional force. Furthermore, the movement of the shot bullet 7 [ causes the adjacent shot bullet 7 to move in a chain reaction, and the dent 12'B is also formed on the opposite side of the dent 12B.
occurs. (3) FIG. 4 is an explanatory view of one layer of scattered bullets 7, which are in contact with the bottom disc 21, among the lost bullets 7 filled in the cartridge holder 20, viewed from the opening 4 of the circle 22, and the protrusion 23 is omitted. This is what I did. Since the gap between the shot shot 7G and the shot shot 7I is small, the shot shot 7F is attached to the front surface 26 of the bottom disk 21 (Fig. 2).
It is rising from. During sudden acceleration/deceleration, the shotgun 7F becomes the shotgun 7G and R due to inertial drag! Scattered bullet 7 because it cuts between bullet 7I
G and the shot 71 are moved in the direction of their respective arrows, that is, in the circumferential direction, and the shot 7G, the shot 7]1 and the lost bullet 7 are moved.
Not only does the contact pressure between I and shot 7J increase,

The cavity 25 of the cartridge 20
The dent caused by the lost bullet 7 that comes into contact with all the surfaces surrounding the gun is automatically formed by the suction force during firing, and this dent remains as an impression of residual strain from the muzzle of the gun.

In the figure, dent 12B>dent 12C @- is shown. This is because the load due to the inertial drag of the shotgun 7 in front is applied to the shotgun 7 adjacent to the rear, and the appearance of the impressions applied to the cartridge 20 that fell and was recovered after ejection proves this. are doing. This is similar to the fact that the water L-bi of Kameyo increases as the depth increases. Also, the frictional force between the shotguns 7 is weaker at the front.

′! I] do it. In FIG. 1 (a part of the lost bullet 7 [Y1 omitted), the shot bullet 7N bites into the inner end 24 of the protrusion 23 by moving in the radial direction, creating a gate. Since the thickness L of the protrusion 23 is smaller than the diameter of the bullet 7N, the area of the mutual pressure contact area is small, so the depth of the dent created on the inner end surface 24 is greater than the depth of the dent created on the inner surface of the circle f522 by the bullet 7H. It gets deeper. Furthermore, the shot 70 is also applied to both four sides of the protrusion 23.
A dent is formed by the movement of the shot bullet 7P in the circumferential direction, that is, in the direction of the arrows facing each other. In this way, a large number of dents are formed on the inner end 24 and both ends of the protrusion 23. Since a large number of protrusions are required for the cartridge 20 to perform its functions, providing the protrusion 23 is one of the essential components of the protrusion 23.

Therefore, the ammunition barrel 20 reaches the gun [] and is ejected while the shotgun 7 contained therein is firmly attached. still,
The element that determines the opening degree of the ejected shotgun 7 is the protrusion 23.
The number N and shape of . The size of the protrusion 23 shown in FIGS. 1 and 2, that is, the length 1, the protrusion amount H, and the thickness,
By appropriately designing the number N of protrusions, the cartridge 20 can be made to meet the purpose of q/t firing.

The shot bullets 7 shown in FIG. Since the defeated bullets 7 are spherical, there are many gaps between them that communicate with each other to the front part 26 of the disk 21.The cartridge 20 has no holes or slits, so there is no air leakage. The air pressure in this gap increases by L in response to the total pressure, and the air pressure reaches a saturated state after an extremely small amount of time has passed after the gun is ejected from the muzzle.Hereinafter, this saturated air pressure will be referred to as the internal pressure of the cartridge. Since the outer shape of the bottom disk 20 is not streamlined, the boundary layer of the relative wind flowing on its outer surface separates, creating a turbulent wake (wake), and the pressure acting on the rear end 27 of the bottom disk 21 is low. Therefore, the bottom disk 21
The internal pressure of the ammunition cylinder acting on the front surface 26 and the rear end surface 27
The shape drag caused by the pressure difference between the low pressure and the low pressure acting on the shell decelerates the cartridge 20 along with the residual drag caused by the generation of shock waves. Hereinafter, this deceleration function will be referred to as an air brake.

、風圧抵抗を容易に排除してあまり減速されず、暫時遷
音速の範囲で飛行する。Further, as long as the shotgun 7 is inside the ammunition cylinder 20, the total pressure received from the front is balanced with the internal pressure of the ammunition cylinder. Since the inertial force of the high-speed, high-specific-gravity lead alloy shotgun 7 trying to maintain its speed is large, the light connection with the ammunition cylinder 20, which is decelerating due to the air brake action, is easily released by this inertial force. The defeated bullet 7 in the first layer detaches from the cartridge 20 and begins to fly alone. This initial withdrawal start point is defined as ′′,
It goes without saying. Subsequently, the shot bullets 7 in the second layer also no longer receive the X5 effect as the lost bullets 7 in the first layer detach, so the frictional force that was acting between the lost bullets 7 decreases and the connection becomes loose. , he started to leave after the first lap. As a result of this continuous withdrawal, all defeated bullets 7 become carriers 2.
This completes il IBa from 0. Let us denote this completion point as 'F2. Since the cartridge 20 containing the shotgun 7 has a large amount of kinetic energy, it easily eliminates wind pressure resistance and is not slowed down much, allowing it to fly within the transonic speed range for a while.

当然である。Therefore, in a ten-barrel gun, compared to normal loading where all the defeated bullets start dispersing all at once at the same time as the muzzle qt: IJJ, a time lag is provided after the muzzle ejection to delay the initial dispersion, and even after that, a new dispersion starts. Naturally, the pattern of loading bullets using the cartridge 20 that continues for a certain period of time becomes noticeably denser.

ある。Therefore, if a normal bullet is used, unless a diaphragm barrel is used, the density of the pattern will be insufficient, and even at shooting ranges where capturing prey or crushing clay targets is extremely uncertain, this cartridge 20 can be used. The loaded bullet can be fired from the flat barrel to ensure that it achieves its purpose. FIG. 5 is an end view showing the construction of the cartridge 30 of the second embodiment, and FIG. 6 shows Y-Y in FIG. 5. The ammunition barrel 30 is formed integrally with the bottom disk 21 and the cylinder 31, and has a cavity 25 inside, which is similar to the first embodiment, but instead of the three protrusions 23 shown in FIG. One equilateral triangular prism protrusion 32 is integrally formed with the bottom disk 21 and protrudes from the inner surface of the bullet holding section 30, that is, the axis of the inner body 26 of the bottom disk 21. This is an example.

ある。This protrusion 32 is a triangular pyramid (32^) as shown by the broken line.
Alternatively, it can be made into various shapes such as a polygonal prism (cone) or a cylinder. Furthermore, the cylinder 31 has a bullet-closing cylinder (31B) having the same diameter and a length of 12 integrally protruding from the tip of the bullet-closing portion (31A) having a length of 11 corresponding to the protrusion 32. Contains the entire area (length L) of lead bullets 7
This structure prevents the gun from coming into contact with the inner surface of the barrel.

Due to the inertial drag of each lost bullet 7 caused by sudden acceleration during firing, the lost bullets 7 move in the radial and circumferential directions, as detailed in sections (2) and (3) of the first embodiment. Since they will move to the next position and attack each other, the protrusion 32
There are many indentations on the outer surface of the cylinder 31.
Together with the impressions formed on the inner surface of the cartridge, it functions to lock the shotgun 7 in the cartridge holding cylinder 30, and the other construction is the same as in the first embodiment.

The opening degree can also be adjusted by providing a plurality of notches (slits) 33 from the tip of the cover cylinder 31B. Its action is that after being ejected from the muzzle, the tip of the shotgun cover cylinder 31B or the notch 33 bends outward and opens due to wind pressure, acting as an auxiliary air brake, which facilitates the separation of the shotgun 7 from the cartridge holding cylinder 30. Plow like you do. The cartridge 40 of the 81st example of the third example is

いる。The action of this cartridge 40 is similar to that of the first or second embodiment, but the total surface area of the protrusion 41 and the protrusion 42 is larger than the surface area of the protrusion in the first or second embodiment.
The number of impressions produced during firing is large, and the degree of spread is therefore narrow, making it suitable for loading bullets that require a more dense pattern.

はこれを−・部図示省略した。In the ammunition barrel 50 shown in FIG. 8 showing the fourth embodiment, the outer diameter d of the cylinder 51 is slightly smaller than the basic diameter of the barrel, and the outer diameter D of the bottom disk 52 is equal to the basic diameter of the barrel. They are almost equally balanced. (Dad). That is, the ammunition cylinder 50 has a shape with a flange (annular flange) 53 protruding from its rear end, and the other configurations are the same as those in FIGS. 5 and 6 of the second embodiment except for the notch 33. In addition, the width W of the flange 53 portion is the width W of the bottom disk 52.
The thickness does not have to be the same as that of , and the outer and inner surfaces thereof may be slightly tapered, as shown by the broken line 51^. Figure 8 shows that after the 9P barrel 50 is ejected from the muzzle, the qt exit axis S-S is caused by f1f, etc.
This is an exaggerated illustration of the state 73 tilted relative to the injection axis S.

It becomes the {I′L position. lI on the front face 54 of the flange 53
．． '(is F), and the relative wind caused by the flight of the cartridge 50 is F.
Expressed as
A component force r of the air force due to 1F acts. Therefore, rf(
A restoring moment of ``force) x line segment PC (moment arm)'' is generated, and the cartridge 50 rotates counterclockwise around the center of gravity G until its axis O-0 coincides with the ejection axis 3-5. In other words, the flange 53 functions as a stabilizer for stabilizing the flight attitude of the cartridge 50, and this function corresponds to the horizontal and vertical tail C composite function of an airplane. Therefore, after ejection, the cartridge 5 continues to fly coaxially with the ejection axis, so that the shotguns 7 are released uniformly and an ideal circular pattern can be obtained.

ターンで飛行する効果を有している。<Effects of the Invention> As described above, the ammunition barrel of the present invention has a bottom disk having an outer diameter that is approximately the same as or slightly smaller than the diameter of the shotgun, and an outer diameter that is approximately equal to the outer diameter of the bottom disk. A cylinder with no notch in diameter, or a single piece with a common fill line, is hollow inside and has a diameter of 1 m, and has at least one protrusion in the cavity. Since this is an integral part of the cartridge projecting from the muzzle, the shotgun is retained internally in the cartridge for a while after being ejected from the muzzle, and the dispersion of the shotgun is restrained. It has the effect of narrowing the spread and flying in an ideal dense pattern.
