Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern controller for a shotgun bullet used for target shooting and hunting.

[0002]

2. Description of the Related Art As shown in FIG. 1, a generally known normal round has a shell 1 having an outer casing 2 and a shell bottom 1a having a detonator 3 mounted at the center of the rear thereof, an explosive 4, a gas seal 5 and a cushioning material 6. The feed 9 (also referred to as a wad) and the shot 7 are sequentially filled, and the front end opening portion of the outer cylinder 2 is folded inward toward the inside (six in the drawing) to form a mouthpiece 8 (also called a crimp). It is sealed with ().

Also, the barrel of a shotgun is provided with an aperture for adjusting the spread of shots, with the exception of the exception. That is, a negative with a slightly enlarged muzzle, that is, a skeet diaphragm barrel (10A in FIG. 3) is used for short-range shooting,
Further, for long-distance shooting, a full-throttle barrel (10B in FIG. 4) that is suitable for narrowing down the muzzle portion and densely collecting shots is suitable. The degree of squeezing is intermediate between these, and for example, for hunting, many hunters love the improved flat barrel barrel with a slightly narrowed muzzle. In addition, in FIG. 3 and FIG.
1A and 11B are muzzles, 12 is a star, 13 is a skeet diaphragm, 14 is a full diaphragm cone, 15 is also parallel, 16
Is the inner surface of the barrel forming the barrel cavity 17.

[0004]

As described above, with a few exceptions, the function of adjusting the opening degree of shots to be ejected is generally entrusted to the squeezing of the barrel, so that the appropriate spreading or dense pattern can be achieved. The current situation is that it cannot be adjusted. Here, the pattern, in horizontal shooting, at a predetermined distance on the emission axis, refers to a bullet hole pattern generated on a plane provided so as to be orthogonal to the emission axis, and the portion where the bullet holes are most dense, When surrounded by a circle with a predetermined diameter,
The percentage of the number of bullet holes in the circle and the number of shot particles filled in the shot before firing is called the pattern percentage (collection rate).

Therefore, the conventional pattern generation will be described below. 1. Deformation over time of bullets ejected from the squeeze squeeze barrel (10A) (Fig. 3) The shots 7 are pushed by the feed 9 by the explosive pressure and agglomerate, and the shots become a cylindrical bullet and reach the muzzle 11A. . Since the diameter of the skeet diaphragm 13 is enlarged toward the muzzle 11A, there is no increase in resistance due to the skeet diaphragm 13 at the time of firing, and the projectile immediately after firing from the muzzle 11A has a cylindrical shape as shown in the axial sectional view shown in FIG. There is.

OO in FIG. 5 is an emission axis line and an arrow indicates an emission direction. Since the bullet velocity at the time of launch is a transonic velocity that exceeds the velocity of sound, the exposed shots 21, 23, 2 at the foremost end of the column in FIG.
The total pressure of the relative wind (the sum of the dynamic pressure and the static pressure) directly acts on 5, 5 and 27, and the exposure shots 21, 23, 25, 27 are forced to decelerate. As is well known, a spherical shot having a large mass and containing lead as a main component is flying at a high speed, so that its kinetic energy is extremely large. And the exposure shot 2
The subsequent second-layer shots 22, 24, and 26 located behind 1, 23, 25, and 27 have the same velocity due to their own inertial force as well as the large inertial forces of the shots present in the rear. Exposure shots 21, 2 at the front end in order to maintain
Instantly interrupt between 3, 25 and 27.

Thus, for example, the first layer shots 21 and 27
Is repelled and moved in the radial direction as shown by the arrow in the figure, and the dispersion of the shots 7 starts.

Then, the rear shot, for example shot 28,
Break in between the two shots located diagonally forward,
As the shot 19 is ejected to the outside, the interrupting action continues to occur, and as shown in FIG. 3, the shape S1 of the bullet column changes to a mushroom shape in which the front bulges at a position within 1 meter in front of the muzzle 11A. .

Even in a bullet column in which shots are densely packed, there are gaps between the spherical shots 7 and they communicate with each other. That is, there are many communication passages from the front end to the rear end of the bullet column, and part of the relative wind blows backward through these communication passages. However, the air flow passing through the communication passage having a complicated shape is blocked by the flow resistance and the flow velocity decreases.

Therefore, as shown in FIG. 5, since the flow velocity V of the air flow flowing outside the bullet column is faster than the flow velocity v of the air flow in the communicating passage, the pressure P of the void (for example, the voids 20A, 20B) in the bullet column is It is higher than the pressure p on the outside of the bullet column. This pressure difference (P
By -p), the shots (for example, shots 29A, 29B) are pushed out in the radial direction as shown by the arrows, and this action contributes to the above-mentioned interruption action to promote the spread of the shots.

Therefore, before the bullet column flies 2 meters from the muzzle 11A, the bullet column changes into a disc shape as shown by S2 in FIG. As described above, since the velocity component in the radial direction is given to the shots 7, the diameter of the bullets rapidly increases, and the lengths of the bullets (the thickness of the disk shape are changed due to the difference in wind pressure resistance received by each shot 7). Also increased,
The whole rapidly grows into a large expanded bulge, producing a pattern suitable for close range shooting.

2. Deformation of a bullet column ejected from the full-throttle barrel (10B) with time (FIG. 4) In the full-throttle barrel 10B, when the diameter of the inner surface 16 of the barrel decreases, that is, the cone 14 and the parallel 15 pass, The shape of the pillar is forcibly deformed into an elongated shape. Moreover, since this shape change is suddenly performed, the agglomeration of the shots 7 is loosened, and the shots 7 are fired from the muzzle 11B in a state of loose shots. This is similar to crowds rushing into a narrow entrance and rushing into it after passing through the entrance.

Therefore, since a gap is formed between the shots 7, there is almost no interruption action as described above, and the muzzle 11B
About 1 meter in front, the shape of the vertebra becomes a real shape as shown by T1 in FIG. 4, and the shape is completely different from the mushroom shape of the bullet ejected from the skeet diaphragm barrel 10A.

Thereafter, the shots 7 behind the bullet column are blocked by the shots 7 located in front of them and are not directly subjected to wind pressure due to the relative wind. Therefore, the velocity at the time of firing is maintained to catch up with the shots 7 in front. They come into contact with each other, and as described above, they are interrupted by the inertial force between the front shots 7. Therefore, the shots 7 on the outer side of the rear of the bullet column move in the radial direction, and the shape of the bullet column extends from the length L1 to L2 as shown by T2 in FIG. Transforms into an inflated one.

Further, this expansion continues forward,
Bullets will fly with increasing diameter and length. That is, full-scale spreading of the shot 7 starts. However, since the start of full-scale spreading of this shot is later and slower than when it is ejected from the skeet squeezing barrel 10A, it is fired from the skeet squeezing barrel 10A at a predetermined same shooting distance. It shows a much higher pattern percentage than that of the above, and is similar to the full aperture barrel 10B suitable for long-distance shooting.

Therefore, in view of the present situation in which the opening degree of the shots to be ejected is all left to the aperture of the barrel, the object of the present invention is to improve the flat cylinder by the pattern controller incorporated in the shotgun shell, or Skeet squeezing or firing from any barrel that has no squeezed portion due to cutting the barrel, etc., made it possible to generate a significantly dispersed or dense pattern compared to the case of using commercially available normal shell It is a thing.

[0017]

Means for Solving the Problems The structure of the present invention for attaining the above object is to provide an explosive charged with a detonator,
In a shotgun bullet in which the feed, shot and pattern controller are filled and the opening of the shell is sealed with a mouthpiece, the pattern controller is composed of a controller and a support, and the controller has a predetermined shape. A rotating body formed by rotating around the axis of the pattern controller, the outer diameter of which is slightly smaller than the inner diameter of the applicable shotgun shell, and at least one inclined surface on the side facing the shot, A through hole is formed in the axial center of the controller, and a plurality of columns that are integrally provided with the controller and project on the side facing the shot are arranged at equal intervals and at target positions around the axis of the controller. The center line and the axis of the controller are on the same virtual plane, and the distance between the axis of the controller and the part on the column that is the longest distance from the axis of the controller is a predetermined length. It is a feature.

[0018]

According to the present invention, the pattern controller enters the gun cavity together with the shot due to the explosion of the explosive, and when the pattern controller passes through the gun cavity, the outer surface of the controller and the outer surface of the support column are moved. Is supported by the inner surface of the barrel and controls the control element in a posture that is completely vertical to the axis of the barrel cavity, and fires it from the muzzle. Further, the control element forcibly moves the shots pushed from the rear in the radial direction or the axial center direction by the inclined surface, and when the predetermined shot distance is reached, the control element performs the action of spreading the shots into the optimum bullet column. Depending on the through hole, the shot density in the central part of the spread bullet column is increased, so it can be fired from an improved flat tube, or a skeet throttle, or a true cylinder that has no throttle portion due to barrel cutting etc. However, the pattern controller built into the shotgun shell enables the ideal pattern control in both short-range and long-range shooting.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. 6 to 8 show the first embodiment, FIG. 6 is a partial sectional front view of the pattern controller 30, FIG. 7 is a left side view of the pattern controller 30, and A--O--A of FIG. The cross-sectional site of is shown. FIG. 8 is a cross-sectional view of the essential parts of a shotgun bullet incorporating the pattern controller 30.

The pattern controller 30 is of a type that diffuses shots, and is composed of a controller 31 and a plurality of (four in the illustrated example) struts 32 integrated. The controller 31 is an annular one, and in FIG. 6, the axis O- of the pattern controller 30 is
On a virtual plane including O, a predetermined point based on the axis O-O, that is, a figure in which a, b, c, d, e, f, and a are sequentially connected by a straight line, It is a rotating body having a shape represented by a trajectory of a figure when it makes one rotation around.

On the rear surface of the control element 31 (on the side where the support column 32 is integrally formed), the first inclined surface 33A is a truncated conical surface whose radius becomes smaller toward the rear, and the first inclined surface 33A.
Two inclined surfaces of the same truncated conical surface, that is, the second inclined surface 33B of the truncated conical surface are formed, and a through hole 34 having a diameter D1 sharing the axis is provided in the axis.

The radius R1 of the controller 31 is the radius R of the inner surface of the outer cylinder 2 of the shell 1 (FIG. 8) having the corresponding diameter (caliber) of the barrel.
The diameter is extremely slightly smaller than 3. The support column 32 is in the shape of a rectangular flat plate, parallel to the axis O-O of the pattern controller 30,
The short sides are oriented in the radial direction, and they are placed at target positions at equal intervals.
It is formed integrally with the first inclined surface 33A and the second inclined surface 33B. Further, the support column 32 may be a support column 32A having a tapered chamfered end. Controller 31
The diameter of the bottom surface is D2 on the front surface of the
Is provided with a conical baffle surface 35.

An imaginary line defined by the intersection of the respective central cross sections of the width w and the thickness t of the column 32 at the rear portion excluding the integrally formed portion is called the center line of the column 32 and is indicated by XY in FIG. It is shown. In addition, the center line of the support column 32A is a bent straight line of X1-Y1. The center lines X-Y and X1-Y1 are both on the same virtual plane as the axis O-O of the pattern controller 30.

Further, the portion of the column 32 having the longest distance from the axis O--O of the pattern controller 30 is the outer surface 36 thereof.
And its shape is an arc surface centered on the axis O-O having a radius R2 of a predetermined length.

FIG. 8 shows a case in which a pattern controller 30 is loaded in accordance with the normal bullet of FIG. 1, and a known shot cover (also called a shot cup) 37 having a cup-shaped slit 37B next to the cushion material 6 is provided. , The shot 7, and the pattern controller 30 are filled in this order and sealed by the mouthpiece 8.
Further, instead of the feeding 9 shown in FIG. 1, it is also possible to use a known single feeding in which the gas seal 5, the cushion material 6 and the shot cover 37 are integrally molded.

Since the shot cover 37 has a thickness t2 and an inner surface 37A has a radius R2 and is substantially equal to the radius R2 of the outer surface 36 of the column 32, the outer surface 36 of the column 32 inserted into the shot 7 is covered.
Closely contacts the inner surface 37A of the shot cover 37.

Further, since the radius R1 of the outer surface 31A of the control element 31 is slightly smaller than the inner diameter R3 of the outer tube 2, the front surface of the pattern controller 30 is the outer surface 31A of the control element 31 and the inner surface of the outer tube. 2A, the rear side is the outer surface 36 of the column 32
Is supported by the inner surface 2A of the outer cylinder via the shot cover 37. Therefore, the pattern controller 30 is loaded with its axis O-O aligned with the axis M-N of the outer cylinder 2 of the cartridge 1. The shots 7 are also filled in the through holes 34.

The operation of the first embodiment will be described below. When the explosive 4 explodes, the shot 7 filled in the shot cover 37 pushes the rear surface of the controller 31, that is, the first inclined surface 33A and the second inclined surface 33B forward, so that the pattern controller 30 does not It advances together with 7, pushes back the mouthpiece 8 and enters the gun cavity 17.

As shown in FIG. 8, the folded portion 8 of the mouthpiece 8
Strictly speaking, the thickness t1 of the outer cylinder 2, the radius of curvature r of the tip portion, the width w of the folded portion, and the depth h of the folded portion of A are not uniform depending on the portions on the circumference. . Therefore, even if the folded portion 8A is pushed in the direction of the axis MN with the same force, the folded portion 8A is pushed back from a portion having a weak sealing force, and the ejection action for releasing the winding 8 is started.
Tends to be inclined with respect to the axis M-N. In order to prevent this, since the sturdy column 32 is integrally provided with the controller 31, the pattern controller 30 is
The mouthpiece 8 can be released in a state where the axis O-O coincides with the axis M-N of the outer cylinder 2 of the shell 1.

Further, while the pattern controller 30 is passing through the gun barrel 17, the controller 31 may be tilted with respect to the axis AA of the gun barrel 17 due to the influence of uneven lead lead on the inner surface 16 of the barrel and other causes. Also, the outer surface 31A of the controller 31 and the support 32
The outer surface 36 of the barrel together with the shot cover 37
The control element 31 is supported by the axis A of the gun cavity 17.
It is fired from the muzzles 11A and 11B in a completely vertical posture with respect to -A.

As is well known, the radius R3 of the inner surface 2A of the outer cylinder of the shell 1 and the radius of the gun cavity 17 are substantially equal. Immediately after firing, the pattern controller 30 is a controller 31 that is in close contact with the front of the bullet column.
The front end surface 31B and the wind guide surface 35 are forced to decelerate due to the relative wind pressure. On the other hand, since the relative wind does not act directly on the group of many shots 7 located behind the control element 31, the group of shots 7 in the rear tries to maintain the same velocity by its own large inertial force, and Shots in contact with the inclined surface 33B and the first inclined surface 33A, for example, a shot 7a
Is pushed forward.

Therefore, the shot 7a pushed from the rear is the second
The radial movement is forced along the inclined surface 33B and the first inclined surface 33A as indicated by an arrow, and the first inclined surface 33A
And all the shots 7 located behind the second inclined surface 33B are separated from the entire circumference of the control element 31 to the outside in a minute time, and are rotated around the axis AA (ejection axis) of the gun cavity 17. Fly so that it is evenly distributed over.

In this way, each shot 7 is provided with a large component in the radial direction, as shown by shot 7a in FIG. 7 by way of example, so that when it reaches a predetermined shooting distance, it has a diameter larger than that of a normal shot. It has a large pattern because it is scattered into a much larger bullet.

A shot located in or behind the through hole 34, for example, a shot 7b is also strongly pushed by a group of shots 7 behind it, so that the axis O- is eliminated while eliminating the relative wind pressure. It advances in the through-hole 34 in the O direction as shown by the arrow, and jumps out in front of the controller 31 so that the approximately gun barrel 17
Although it flies in the direction of the axis AA (exit axis), the degree of divergence is extremely small because no radial velocity component is applied.

Therefore, since a large number of shots 7 hit near the central portion of the pattern, the donut type pattern in which the density of the bullet holes in the central portion of the pattern at a predetermined shooting distance is not reduced is prevented. Further, since a part of the relative wind is guided to the wind guide surface 35 and blown into the through holes 34 as indicated by an arrow F in FIG. 6, it acts to suppress the passage number of the shot 7 through the through holes 34. By properly setting the diameter D2 of the front surface of the wind guide surface 35, the bullet hole density near the center of the pattern can be adjusted to an ideal one.

FIG. 9 and FIG. 10 show a diffusion type pattern controller 40 of the design modification of the first embodiment. 9 is a front view of an axial cross section of the pattern controller 40, FIG. 10 is a left side view of the same, and XY indicates a cross sectional portion of FIG.
It is shown that the structure is integrated with the column 42.

The controller 41 makes a closed figure in which points e, a, b, c, d are connected by a straight line and d, e are connected by a curve, one revolution around the axis O--O of the pattern controller 40. The radius of the outer peripheral surface 41A is the same radius R1 as the pattern controller 30 of the first embodiment. Further, the control element 41 has a through hole 44 in its axial center, a rear surface facing the shot 7 is formed with a concave curved surface 43, and three circular shaft-shaped support columns 42 are provided in the control element 41. It is projected integrally with the inclined surface 43 in parallel with the axis OO at equal intervals.

As in the first embodiment, the center line C of the column 42 is
-C is on the same virtual plane as the axis O-O of the control element 41, and the virtual straight line 46 perpendicular to the plane of the drawing due to the intersection of this virtual plane and the outer side of the support column 42 and the axis O of the control element 41.
The distance from -O is the radius R of the outer peripheral surface 41A of the controller 41.
1, the virtual straight line 46 is the part of the column 42 that has the longest distance from the axis OO. Front end face 41 of controller 41
B is chamfered 49 on the outer peripheral portion.

This pattern controller 40 shows an embodiment used for loading without using the shot cover 37 as in FIG.
The struts 42 to be inserted into the filled shots 7 are supported by the virtual straight lines 46 directly contacting the inner surface 2A of the outer cylinder of the shell 1. Other configurations of the bullets are the same as those in the first embodiment.

The operation of the pattern controller 40 of this modified design is similar to that of the pattern controller 30 of the first embodiment, but the inclined surface is one continuous gentle concave curved surface of the inclined surface 43. The velocity component in the radial direction imparted to the shot (eg, shot 7c) moving along the concave curved inclined surface 43 is small. Also, the diameter D3 of the through hole 44
Is larger than the diameter D1 of the pattern controller 30 of the first embodiment, and further, since the baffle surface 35 for suppressing the passage of the shot 7 through the through hole 44 does not exist, it passes through the through hole 44, The number of particles of the shot 7 moving in the direction of the emission axis is larger than that of the pattern controller 30 of the first embodiment. Therefore, the pattern percentage of the pattern controller 40 is an intermediate value between the pattern controller 30 for close range and the normal round of the first embodiment, which is suitable for short range shooting hunting rounds.

Next, a second embodiment of the present invention will be described with reference to FIGS. 11 to 13. The pattern controller 50 of the second embodiment is of a type intended to generate a dense pattern. FIG. 11 is a front view of a cross section of a main part, FIG. 12 is a left side view thereof, and X2-O-X3 are 12 shows a cross-sectional portion of FIG.

The pattern controller 50 includes a controller 51 and a support 5
In the same manner as in the first embodiment, the controller 51 is composed of two parts, and the controller 51 forms a figure in which a, b, c, d, e, f, g, and a are connected by a straight line around the axis O--O of the pattern controller 50. It is an integrally molded rotating body that is formed by rotating. On the rear side of the control element 51, there is provided an inclined surface 53 having a truncated conical surface whose radius decreases toward the front and an inner surface of the cylindrical portion 58, that is, a cylindrical surface 58A.

The control element 51, including the cylindrical portion 58, has the same outer radius R as the control element 31 of the first embodiment.
It is 1. Further, the controller 51 has a through hole 54 that shares an axis with the axis O-O, and has a wind guide surface 55 and a chamfer 5 on the front surface.
9 is equipped.

The four columns 52 of the same shape are cylindrical pieces having the same outer diameter radius R1 as the control element 51.
From the cylindrical portion 58 integrally formed at equal intervals, and outwardly in the radial direction so that the distance between the central portion 52A of the outer surface of the cylindrical portion 58 and the axis O-O becomes a predetermined length L. Inclined to.

A center line C-C shown in FIG. 11 is a straight line connecting the central portions of the width W and the thickness t of the support column 52, and is a line OX in FIG.
It coexists with the axis O-O of the pattern controller 50 on a virtual plane (perpendicular to the paper surface) indicated by 2. Further, in order to act as a stabilizer for stabilizing the flight attitude of the pattern controller 50 after injection, a protrusion edge 57 is provided on the outer surface end portion of the column 52, and the air flow F flowing outside the pattern controller 50 is provided.
It is also possible to receive the wind pressure of.

The pattern controller 50 is inserted into the shell 1 using a well-known feed inserter (also called a wad guide or finger) after filling the shell 1 with the shots 7, and at that time, the feed inserter is used. Since the end of the column 52 is narrowed and the column 52 is deformed so as to be parallel to the axis of the pattern controller 50, insertion is easy.

Since the material of the pattern controller 50 has a proper elasticity which will be described later, the support column 52 is pressed against the inner surface 2A of the outer cylinder of the shell 1 by the restoring force due to the elasticity and the rear portion of the pattern controller 50 is fixed. Since the controller 51 is in contact with the inner surface 2A of the outer cylinder at the front portion, the pattern controller 50 is provided with the winder 8 with its axis shared with the axis of the shell 1.

The operation of the second embodiment will be described mainly on the points different from the first embodiment. Immediately after the pattern controller 50 is fired from the muzzle 11A, 11B, the controller 51
Relative wind pressure acts on the front surface of the pattern controller 50,
Is forced to decelerate.

A large number of shots located behind the inclined surface 53,
For example, the shot 7e of FIG. 13 moves diagonally in the axial direction along the cylindrical surface 58A and the inclined surface 53 as indicated by the arrow, due to its own inertial force and the inertial forces of a large number of shots 7 located behind. Then, it enters into the through hole 54. Also, the through hole 54
The shot located at the rear of the shot, for example, shot 7f in FIG. 13 is also pushed by the shot at the back 7 and enters the through hole 54.

Although the diameter of the through hole 54 is smaller than the diameter of the cylindrical surface 58A, the passage force of this narrow passage and the wind pressure resistance of the relative wind are eliminated by the large kinetic energy of each shot 7 from the through hole 54. Escape, axis A of gun cavity 17
-Fly in the A (exit axis) direction.

The bullet column after passing through the through hole 54 has an elongated shape in which the density of the shots 7 is sparse. Since the subsequent change in the shape of the bullet column and the action are in accordance with the change over time of the bullet column ejected from the full aperture barrel 10B, the pattern of the bullet loaded with the pattern controller 50 is fired under the same conditions as this. It will be more dense than the normal shot.

Further, the shot 7 at a position close to the column 52 in FIGS. 12 and 13, that is, near the outer peripheral portion in the bullet column.
As in the case of the shot 28 shown in FIG. 5, since the shot is interrupted between the forward shots 7 which are forced to decelerate, the interrupted outer shot 7g (corresponding to the shot 19 of FIG. 5) is flipped outward.

In this way, there is also a moderate number of shots 7 that are given radial velocity components,
It is possible to reduce the overcrowding of the central portion of the pattern, and the pattern at a predetermined shooting distance has a uniform density.
Further, if the length Z of the cylindrical portion 58 shown in FIG. 13 is increased,
The number of shots 7 provided with the radial velocity component described above is reduced.

Next, FIG. 14 shows an example of design change of the second embodiment.
And FIG. 15 will be described. FIG. 14 is a partial cross-sectional front view of the pattern controller 60, and FIG.
X3 is a cross-sectional site in FIG.

The pattern controller 60 is of a dense type, and is composed of a controller 61 and a support 62, which are integrated with each other.
Is a rotating body of a figure indicated by a, b, c, d,
Cylindrical part 5 formed in the pattern controller 50 of the embodiment
I don't have 8. In addition, the inclined surface 63 of the truncated conical surface having a smaller diameter toward the front and the baffle surface 65 of the truncated conical surface share a truncated surface, and the shared truncated surface forms a through hole 64. The radius of the outer surface of the controller 61 is the same as the radius R1 of the pattern controller 50 of the second embodiment.

The four cylindrical pillar-shaped supports 62 having a radius R1 on the outer surface are arranged parallel to the axis O--O of the control element 61 and at equal intervals, and are integrally formed with the control element 61 on the inclined surface 63. ing.

With such a structure, the portion of the pillar 62 that is the longest distance from the axis O--O is the outer surface thereof, and the distance is the radius R1 as shown in FIG. Further, the center line S-S of the support column 62 is on the same virtual plane as the axis O-O.

The pattern controller 60 is different from the pattern controllers 30, 40 and 50 in that after the cushion material 6 is filled in the shell 1, the pattern controller 60 is inserted so that the end surface 62A of the support column 62 is in contact with the upper surface of the cushion material 6. Then, a fixed amount of shots 7 is filled from the through holes 64 and sealed by the mouthpiece 8.

If the width W1 of the strut 62 is increased and the gap g is set to be equal to or smaller than the radius of the shot 7, since the shot 62 is blocked by the strut 62 and the shot 7 does not come into contact with the inner surface 16 of the barrel like the shot cover 37, No lead will occur. Further, it is possible to incline the support column 62 in the radial direction like the support column 52 or to provide the projecting edge 57.

The operation of the design modification of the second embodiment is substantially the same as that of the pattern controller 50, but since the gap g between the adjacent columns 62 is small, the shots 7 scattered in the radial direction described above.
There is no (7g shot in Figure 12). Therefore, since all of the filled shots 7 pass through the through holes 64, the pattern percentage of the shot loaded with the pattern controller 60 becomes extremely high as compared with the ordinary shot.

In addition to what has been described above, the pattern controller can be made to have performance suitable for the purpose of use by appropriately setting the following four items. (1) Shape and number of inclined surfaces. (For example, use of a plurality of inclined surfaces such as a curved surface and a conical surface or a combination of two curved surfaces) (2) Degree of inclination of the inclined surface. (3) Size of through hole. (4) Cross-sectional shape of the column.

EFFECTS OF THE INVENTION The present invention makes it possible to shoot from a close range to a long range with a single barrel in an ideal pattern by properly using the dispersion type and the dense type bullets with a built-in pattern controller according to the purpose. It is an epoch-making thing that has never been done before. For example, for a target that flies from a short distance and flies in the direction of a bearer or an oblique bearer, a single-barreled continuous fire gun has a built-in dispersion type pattern controller for the first shot, and a normal shot for the second shot. However, if a dense type pattern control device built-in bullet is used for the third shot, it is possible to carry out a long-distance shot with a shot appropriate for the shooting distance for each shot.

Also, in a field shooting competition in which one real hunting gun shoots the second type of trap and skeet, it is advantageous that the bullets can be selected according to the shooting distance on each shooting table.

Further, since the pattern controller has a shape and structure suitable for plastic injection molding, it has an advantage that it can be mass-produced at low cost.
