微々たるもので、期待できるほどの効果はない。Shotgun barrels include a diaphragm barrel that narrows the degree of spread of ejected shots to increase their density, making them suitable for long-distance shooting. A means to improve the pattern percentage (density of bullet hole pattern at a given shooting distance) with a small degree of expansion even when firing from a flat barrel (improved flat barrel, skeet choke, recessed choke, true cylindrical barrel, etc.) without relying on the aperture barrel. As a method, there is a method of changing the bullet speed and the size of the shot particles (shot number), but the improvement is minimal and the effect is not as expected.

なっている。[0005] Also, more than 50 years ago, buckshot stored in a paper bag or mesh bag was loaded into a cartridge, and after it flew a predetermined distance after being ejected, the bag broke, exposing the buckshot, and it began dispersing. Attempts have been made to create a similar design, but with this design, the bag would break while passing through the gun barrel, or the bag would not break at all after firing and would fly in the form of a single bullet with a built-in shotgun. could not be put into practical use. Therefore, the use of an aperture barrel is still the only way to significantly increase the pattern percentage.

散弾７を円筒の前端３３側から見た説明図である。Next, the operation of the present invention constructed as described above will be explained in detail. FIG. 4 is an axial cross-sectional view for explaining the action of the shot 7 accelerated in the gun barrel 13 due to the explosion pressure of the gunpowder 3 (hereinafter referred to as explosion pressure) on the cartridge 20, where 5 is a fiber washer and 13A is an axial cross-sectional view. a gun cavity, the annular projection 24;
24A and 28 are not shown. FIG. 5 is an explanatory diagram of one layer of shotguns 7 near the disc 21, viewed from the front end 33 side of the cylinder, among the shotguns 7 filled in the ammunition cylinder 20.

加速が激烈であるばかりでなく、散弾７は鉛を主体とし
た合金であるから、質量が大きく加速に抵抗する力、す
なわち、慣性抗力が大きい。[0015] Due to the explosion of the gunpowder 3, the cartridge 20 containing the shotgun 7 is rapidly accelerated from a resting state to a transonic speed exceeding the speed of sound within a minute time of about 10-3 seconds. Therefore, not only is the acceleration violent, but since the shot 7 is made of an alloy mainly composed of lead, it has a large mass and a large force resisting acceleration, that is, a large inertial drag.
【００１６】よって、散弾７が抱弾筒２０に及ぼす作用
は次の通りである。

動は連鎖的に隣接する散弾７を移動させ、凹み１２Ｂの
反対面にも凹み１２′Ｂが生ずるのである。Accordingly, the action of the shotgun 7 on the cartridge 20 is as follows. (1) While the disk 21 is forced to accelerate rapidly by the explosive pressure, the opposing shotguns, for example, the shotgun 7A, are trying to maintain the same speed due to inertia. Therefore, the shot 7A is press-fitted into the front surface 26 of the disc 21 in a direction parallel to the axis due to the inertial drag, creating a deep recess 12A. (2) Next, taking shotguns 7B, 7C, and 7D as an example, shotgun 7B gets between shotgun 7C and shotgun 7D due to inertial drag, so shotgun 7C moves outward in the radial direction.
A dent 12B is formed on the inner surface of the cylinder 22, and at the same time the shot 7
D moves radially toward the axis. This results in
It strongly pushes the adjacent shotgun 7E. In this way, the contact pressure between the shot bullets 7 increases, and the shot bullets 7 are fixed to each other by strong frictional force. Furthermore, the movement of the shot 7E causes the adjacent shot 7 to move in a chain reaction, and a dent 12'B is also formed on the opposite side of the dent 12B.

ら射出されるのである。As described in detail above, due to inertial drag during sudden acceleration, each shot 7 moves in the axial and radial directions as well as in the FIG.
As shown in FIG. 2, the interruption of the shotgun 7F causes the shotguns 7G and 7I to move in the direction of the arrow, that is, in the circumferential direction, so that the shotguns 7 are tightly packed into the cartridge holding cylinder 20 and are pushed against each other. A dent is created by the shot bullets 7 that come into contact with all the inner surfaces 23 of the cylinder 22 of the ammunition barrel 20,
Due to this recess and the frictional force between the shot bullets 7, each shot bullet 7 is fixed and restrained within the cartridge holder 20 and ejected from the muzzle.

ほど増大するのと同様である。(3) The depth of the recess on the inner surface 23 of the cylinder 22 and the contact surface pressure between the shotguns 7 are determined at the rear, that is, at the disk 2.
The part close to 1 is the largest, and the parts in the front gradually become smaller. In FIG. 4, recesses 12B>12C are illustrated. 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 state of the residual impression applied to the inner surface 23 of the cartridge holder 20 collected after ejection is such that this It has been proven. This is similar to how water pressure in the ocean increases with depth.

。この飽和状態の空気圧を抱弾筒内圧という。When the cartridge 20 containing the shot bullet 7 is ejected from the muzzle, the sum of the dynamic pressure and static pressure of the relative wind, that is, the total pressure, acts on the front surface of the cartridge 20. Since the shotguns 7 are spherical, there are a number of gaps between them that communicate with each other to the front surface 26 (FIG. 4) of the disc 21. Since there is no slit 10 (cut) in the cartridge cartridge 20, there is no air leakage, and the air pressure in this gap absorbs the total pressure and increases, 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. . This saturated air pressure is called the internal pressure of the cartridge.

ーキという。In addition, the relative wind flowing on the outer surface of the cartridge 20 causes the boundary layer to separate, producing a turbulent wake, which acts on the rear end surface 27 (FIG. 4) of the disk 21. The pressure becomes low. Therefore, the shape drag due to the pressure difference between the internal pressure of the ammunition cylinder acting on the front surface 26 of the disk 21 and the low pressure acting on the rear end surface 27 acts to decelerate the ammunition cylinder 20 together with the wave-forming drag due to the generation of shock waves. be. Hereinafter, this function will be referred to as an air brake.

うになって散開を始めるのである。この最初の離脱開始
時点をＴ１で表すこととする。[0021] As explained in (3) above, the shot bullets 7 in the first layer located at the forefront of the ammunition barrel 20 are lightly anchored to the ammunition barrel 20 by shallow recesses and weak frictional force. Also, shotgun 7
As long as the bullet is inside the cartridge 20, the internal pressure of the cartridge is balanced with the total pressure received from the front. 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 barrel 20, which is decelerating due to the air brake action, is easily released by this inertial force. The shotguns 7 in the first layer detach from the cartridge 20 and begin to fly independently. Let T1 represent this first withdrawal start point.
【００２２】続いて、第２層の散弾７は、第１層の散弾

るのである。Subsequently, the second layer of shotguns 7 are no longer affected by the first layer of shotguns 7, so the frictional force acting between the shotguns is reduced, loosening the lock and allowing them to separate. become a state. In this way, the shotguns 7 in the cartridge 20 are continuously
As the release of the lock progresses, all of the shot bullets 7 contained in the ammunition barrel 20 will eventually come to a state where they can be removed from the ammunition barrel 20.

larger than the cross-sectional area of the opening at the tip. Therefore, in order for the shot bullet 7 to leave the ammunition barrel 20, it must pass through a narrow passage surrounded by the annular protrusion 24. It takes some time until the time T2 when all the shotguns 7 are completely detached. In addition, the annular projection 28 in FIG.
This is also provided to resist the movement of the shotgun 7 and delay its departure.

ある。Since the cartridge 20 containing the shot bullet 7 has a large amount of kinetic energy, it easily eliminates wind pressure resistance and flies at a transonic speed range for a while without slowing down much. When the muzzle ejection time point is T0, the seconds until the start of withdrawal are expressed as (T1-T0), and the seconds that continue detachment are expressed as (T2-T1). (T1-T0) and (T2-T1) have extremely fast flight speeds even in minute seconds, so within those seconds, the cartridges 24 and 24A contain the shot 7,
It has traveled a considerable distance towards its target.

The outer diameter D of the flange 29 is approximately equal to the standard diameter of the shotgun to which it is applied, and the outer diameter d of the cylinder 22 is slightly smaller than the standard diameter, and the other configurations are the same as the cartridge cartridge 20. The width W of the flange 29 does not have to be the same as the thickness of the disk 21, and
It is also possible to provide the outer surface of the flange 29 with a shallow annular groove.

る。FIG. 6 is an exaggerated illustration of a state in which the cartridge 20B is tilted with respect to the ejection axis S-S for some reason after being ejected from the muzzle, and the tilt angle is indicated by θ1. . Since the bullet holding cylinder 20B is made of plastic and is light, the center of gravity when containing the shot bullet 7 as shown in the figure is at a point G slightly forward of the center on the axis 0-0. Flange 29
If one point on the front surface 30 of is P, and the relative wind caused by the flight of the cartridge 20B is represented by F, then a component f of the aerodynamic force due to the relative wind F acts on the point P in a direction perpendicular to the line segment PG. . Therefore, “
A restoring moment of "f (force) x line segment PG (moment arm)" is generated, and the cartridge 20B is centered around the center of gravity G.
Rotate counterclockwise until its axis 0-0 coincides with the injection axis S-S. That is, the flange 29 is connected to the cartridge 20.
It acts as a stabilizer to stabilize B's flight attitude, and this function corresponds to the combined function of both horizontal and vertical tails of an airplane. Therefore, after ejection, the cartridge 20B continues to fly coaxially with the ejection axis, so that the pellets 7 are released uniformly and an ideal circular pattern can be obtained.

ジが高いから、その点を補うことができる。As described above, according to the present invention, the ammunition cylinder for accommodating shot bullets is constructed integrally with a cylinder without a cut end and a disk facing the feeder, sharing their respective axes. The ends are open, the outer diameters of the cylinder and the disc are both slightly smaller than the standard caliber of the shotgun to which they are applied, and at least one annular protrusion or annular protrusion piece is integrally provided on the inner surface of the cylinder. Because of this structure, after being ejected from the muzzle, the shotgun is held inside the cartridge for a while to restrict the dispersion of the shotgun, and the scattering degree of the group of shotguns released from the cartridge is narrowed to fly in an ideal dense pattern. can be done. Furthermore, from the viewpoint of protecting the natural environment, even if less powerful steel shot bullets are used to prevent lead pollution, bullet loading using a cartridge can compensate for this point because the pattern percentage is high.
