Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shotgun aiming training tool that allows effective aiming training without using live ammunition.

[0002]

2. Description of the Related Art Conventionally, aiming practice using a shotgun has aimed at a target, fired a live ammunition, and determined whether or not the aim was correct based on whether the shot hit the target,
There was no way to practice aiming without firing live ammunition. The same is true for rifle fire, aiming at a stationary target and firing a live ammunition, looking at the bullet holes remaining on the target, and determining whether the aim was correct and how wrong the aim was I have. In this way, in the case of rifle shooting, it is possible to use a stationary target and confirm the deviation of the bullet hole from the center of the target, and it is possible for the shooter himself to analyze the results of his own shooting practice .

[0003] However, it is difficult to accurately analyze the result of shooting in practice of clay shooting competition. That is, in clay shooting, since the shooter fires live ammunition toward the clay released into the air, it is good when hitting the clay,
When the live ammunition comes off the clay, the shooter does not know how far away. Therefore, a coach or another third party observes from behind the shooter and gives advice on misalignment by estimating from the direction of the barrel when the shooter fired. Therefore, it is difficult to analyze the results of shooting practice, and unless you are a very skilled coach, you can not give accurate advice,
Also, even if the advice was accurate, the shooter could not sense how far the shot was off as his own sense, and had to be forced to practice irrationally and inefficiently.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems. The aim of the present invention is to determine how far the aim is deviated from the target or how much the aim is deflected. Can be confirmed and analyzed to contribute to the effective improvement of shooting techniques, and even if a shooting instructor or coach advises the shooter, the shooting instructor or coach will not be able to determine the aiming position and aiming position with respect to the target. It is an object of the present invention to provide a shooting aiming tool for a shotgun, which makes it possible to visually observe the degree of deviation at a glance and to give appropriate advice.

[0005]

In order to achieve the above object, according to the present invention, a light beam can be emitted and the optical axis of the light beam can be adjusted by a barrel. It is characterized in that it comprises a light beam launching unit that can be loaded into the shotgun in alignment with the central axis. The light beam travels along an extension of the center axis of the barrel. The path of this light beam is the aiming position, and the shooter or the coach can view the light beam itself or the light beam spot on the object such as the target in a continuous time. Misalignment,
The degree of shake and the like can be observed.

The light beam emitting unit has the same outer shape as that of the cartridge case loaded in the shotgun, and the light beam emitting unit is loaded in the shot chamber of the shotgun. You should be able to do it. The light beam emitting unit may have a laser light source as in the invention of claim 3, or may have a switch for turning on and off the operation of the light source as in the invention of claim 4. It may be. Further, as in the invention according to claim 5, an attachment to be attached to the light beam emitting unit may be prepared according to the specifications of the shot chamber of the shotgun.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a shotgun aiming training device according to the present invention. FIG. 1 shows an example of a double-sided shotgun equipped with the aiming training tool according to the present invention. In FIG. 1, a lower barrel 2, called a lower barrel, and an upper barrel 3, called an upper barrel, are approximately parallel to each other vertically, more precisely, the center axis of the barrel 2 and the barrel 3 is a predetermined distance (for example, 50 meters). ) They are arranged to cross at the location of a distant target. The inner peripheral space at the rear end of each barrel 2, 3 is a chamber 4, 5,
Each of the chambers 4 and 5 is loaded with a cartridge case in which a shot and an explosive are enclosed. In the example shown in FIG.
5 is provided with light beam emitting units 6, 6 according to an embodiment of the aiming training tool of the present invention. As is well known, by releasing the lock, the parts of the barrels 2 and 3 can be integrally rotated in a bent shape with respect to the stock 1, and in this rotation position, the rear ends of the chambers 4 and 5 are rotated. Is opened, the cartridge case or the light beam emitting units 6, 6 can be loaded from this open end. After loading, the barrels 2, 3 are returned to their original positions as shown in FIG. It is designed to lock.

In FIG. 1, reference numeral 8 denotes a lower trigger, 9 denotes an upper trigger, 12 denotes a lower firing pin, and 13 denotes an upper firing pin. Since the configuration of the shotgun itself is well known, a detailed description is omitted.

Next, a specific example of the light beam emitting unit 6 will be described. In FIG. 2, the light beam emitting unit 6
Is formed of a bottomed cylinder 61 and a cylinder 62 having both ends open, and the open end of the cylinder 61 and one end of the cylinder 62 are connected with a screw 63 to form a cartridge case loaded in a shotgun. It is the same as the outer shape. The cylinders 61 and 62 are made of a conductive material such as brass, for example. Cylinder 61
An insulating layer 16 is formed on the inner peripheral surface of the substrate. Insulating layer 16
May be formed by inserting a cylindrical insulating material into the inner peripheral surface of the cylinder 61, or by applying an insulating paint. An electric contact 17 is protruded from the inner bottom of the cylinder 61. The cylinder 61 is a battery chamber, and an appropriate number of button-type batteries 15 are loaded in the cylinder 61 so as to be stacked in series, and a power supply suitable for driving a semiconductor laser chip described later. A voltage can be obtained. The power source is not limited to a button type battery, and any battery may be used.

In the other cylinder 62, the cylinder 61
The separating member 18 is fitted and fixed to the end on the side, and a cylindrical light source holder 65 is fitted and fixed to the remaining inner surface of the cylinder 62. In the light source holder 65, a laser unit 7 having a semiconductor laser chip 10 as a laser light source is fitted and fixed. A laser beam can be emitted from the semiconductor laser chip 10, and the laser beam is emitted from a window 66 formed at the front end of the light source holder 65. Two terminals 21 and 22 protrude from the rear end side of the laser unit 7. One terminal 2
1 is electrically connected to one end of a spring contact 20 held through the isolation member 18 through the isolation member 18, and the other terminal 22 is electrically connected to a cylinder 62. In the state where the cylinder 61 and the cylinder 62 are integrally connected by the screw 63 as described above, one of the electrodes of the battery 15 contacts the electric contact 17 and extends from one end of the cylinder 62 toward the cylinder 61. Contact 20 is in contact with the other electrode of battery 15.

Therefore, one electrode of the battery 15 and the contact 1
7, a closed circuit is formed through the cylinder 61, the cylinder 62, the terminal 22, the semiconductor laser chip 10, the terminal 21, the spring contact 20, and the other electrode of the battery 15, and power is supplied from the battery 15 to the semiconductor laser chip 10, A laser beam is emitted from the semiconductor laser chip 10. In the light beam emitting unit 6 configured as described above, the battery 15 is removed or the cylinder 61 and the cylinder 62 are separated when not in use.

The light beam emitting unit 6 is loaded into the shot chambers 4 and 5 instead of the cartridge case as described with reference to FIG. 1, and is used for aiming training. In a state where the light beam emitting unit 6 is loaded in the shot chambers 4 and 5 of the shotgun, the optical axis of the laser beam emitted from the light beam emitting unit 6 is aligned with the center axis of the barrels 2 and 3. The outer shapes of the cylinders 61 and 62 constituting the main body of the beam emitting unit 6 are finished with high dimensional accuracy, and the cylinders 61 and 62 are finished.
The position adjustment and the inclination adjustment of the laser unit 7 are performed in advance so that the emission position and the emission angle of the laser beam with respect to the outer shape become a predetermined emission position, and the optical axis does not tilt. In order to adjust the position and tilt of the laser unit 7, it is necessary to know the degree of displacement and tilt of the laser beam optical axis with respect to the center axis of the outer shape of the light beam emitting unit 6, in other words, the center axis of the barrel. As one method of knowing the degree of displacement and inclination of the laser beam optical axis, a laser beam is emitted from a light beam emitting unit 6 mounted on a muzzle, and a laser beam is applied to the paper. There is a method of observing the relationship between the position of the beam and the center position of the muzzle to know the degree of displacement and inclination of the laser beam optical axis with respect to the center axis of the barrel. Alternatively, a method of rolling the cylindrical surface of the light beam emitting unit 6 on a flat surface and observing whether the trajectory of the laser beam moving on a plane set at a right angle to the laser beam optical axis is straight or waving. is there. In this method, if the trajectory of the laser beam is straight, there is no displacement or inclination of the optical axis of the laser beam.

The aiming practice using the light beam emitting unit 6 can be performed as follows. A wall or the like is placed at a position about 10 to 50 m away from the shooting position, a target is set on this wall, and a shotgun is aimed at the target. At this time, the spot of the laser beam emitted from the light beam emitting unit 6 mounted on the shotgun is formed at a position corresponding to the aim of the shotgun, in other words, at the center point of the impact pattern. This laser beam spot can be seen by the shooter himself, so the degree of misalignment with respect to the target,
The shooter himself can visually recognize the presence or absence of the aiming shake, the magnitude of the shake, and the like. Therefore, the shooter can recognize the problem of his own shooting by his own judgment and can use it for practice. In addition, the coach and other third parties can also view the laser beam spot, so that appropriate and persuasive advice can be given to the shooter.

FIG. 5 shows the concept of aiming practice in clay shooting. In FIG. 5, the released clay is designated by reference numerals 50A, 5A.
It is assumed that the robot moves along a locus 50 as indicated by 0B, 50C,... 50N. A shotgun is aimed at the moving clay. At this time, the laser beam emitted from the light beam emitting unit 6 loaded in the shotgun is, for example, in accordance with the aiming of the shotgun. In FIG. 5, a locus like a curve indicated by reference numeral 55 is drawn. This curve 55 will be referred to herein as the aiming locus. It can be determined that the closer the aim trajectory 55 is to the clay trajectory 50 together with the temporal element, the better the aim is, and the farther away from the clay trajectory 50, the more the aim is shifted. For advanced clay shooting users, the aiming locus 55 is close to the clay locus 50, and the aiming locus 55 has little swing. On the other hand, in the case of a beginner, the aiming locus 55 greatly deviates from the clay locus 50, and the aiming locus 55 slightly changes, and the fluctuation width becomes large.

Therefore, a wall or the like is placed at a position distant from the shooting position by a predetermined distance, and the clay is released with the wall as a background, or an image of the released clay is projected, and a shotgun of the shotgun is targeted at the clay. When aiming is performed, a spot of the laser beam emitted from the light beam emitting unit 6 is formed on the wall, and the trajectory of the laser beam spot can be recognized as the aiming trajectory 55. By looking at itself, the shooter himself can visually recognize the degree of deviation of the aim with respect to the target, the presence / absence of aim movement, the degree, and the like. Therefore, the shooter can recognize the problem of his own shooting by his own judgment and can use it for practice. In addition, since the coach and other third parties can also view the aiming trajectory 55, appropriate and persuasive advice can be given to the shooter. If the movement of the clay and the trajectory of the aim 55 are photographed by a video tape recorder or the like, it is also possible to analyze a shift in aim, a blur, etc. after practice.

Next, another embodiment of the present invention will be described. FIG. 3 shows another embodiment of the light beam emitting unit.
Shown in In this embodiment, the semiconductor laser chip 10
Switch 25 that turns on and off the power supply to the
Is provided. In the embodiment shown in FIG.
The battery 15, light source holder 65, and laser unit 7 are the same as those in the embodiment shown in FIG. The outer shape of the light beam emitting unit 70 is formed by a bottomed cylinder 71 and a cylinder 72 whose both ends are open, and an open end of the cylinder 71 and one end of the cylinder 72 are connected by a screw 73,
It has the same shape as the cartridge case loaded in the shotgun. It is assumed that the cylinders 61 and 62 are made of a conductive material. The insulating layer 26 is formed on the inner peripheral surface of the cylinder 71. Cylinder 7
An electrical contact 27 protrudes from the inner bottom of the device 1. Cylinder 7
An appropriate number of button-type batteries 15 are loaded in the unit 1 in a stacked manner in series.

In the other cylinder 72, the cylinder 71
An isolation member 28 is fitted and fixed to the end on the side. Cylinder 7
A hole 74 is formed on the side surface of the second member at a position adjacent to the separating member 28, and the slide switch 25 is embedded and fixed in the hole 74. The slide switch 25 is arranged so that the slide operation piece can be slid from the outside of the cylinder 72 and does not protrude from the outer periphery of the cylinder 72. A cylindrical light source holder 65 is fitted and fixed to the remaining inner surface of the cylinder 72. Laser unit 7 having semiconductor laser chip 10 in light source holder 65
Are fitted and fixed. The laser beam emitted from the semiconductor laser chip 10 is emitted from a window hole 66 formed at the front end of the light source holder 65. One terminal 21 protruding from the rear end of the laser unit 7 is connected to one terminal of a slide switch 25, and the other terminal of the slide switch 25 is connected to the isolation member 28 by a spring held through the isolation member 28. The contact 30 is electrically connected to one end. The other terminal 22 of the laser unit 7 is connected to the cylinder 72.

When the slide switch 25 is turned on, one electrode of the battery 15, the contact 27, the cylinder 71, the cylinder 72,
A closed circuit is formed through the terminal 22, the semiconductor laser chip 10, the terminal 21, the slide switch 25, the spring contact 30, and the other electrode of the battery 15, and power is supplied from the battery 15 to the semiconductor laser chip 10. Emits a laser beam. When not in use, the slide switch 25 is turned off.

Similarly to the light beam emitting unit 6 shown in FIG. 2, the light beam emitting unit 70 is loaded in place of a cartridge case in the shot chambers 4 and 5 of the shotgun as shown in FIG. Is done. In a state where the light beam emitting unit 70 is loaded in the shot chambers 4 and 5, the optical axis of the laser beam emitted from the light beam emitting unit 70 is
3, the outer shapes of the cylinders 71, 72 constituting the main body of the light beam emitting unit 70 are finished with high dimensional accuracy, and the emission position and the emission angle of the laser beam with respect to the outer shapes of the cylinders 71, 72 are changed. The position adjustment and the tilt adjustment of the laser unit 7 are performed in advance so that the predetermined emission position and the emission angle are obtained. When the light beam emitting unit 70 is used, the same operation and effect as when the light beam emitting unit 6 shown in FIG. 2 is used can be obtained.

The size of the cartridge case used depends on the specifications of the shotgun. The size of the light beam emitting unit may be prepared according to the size of each cartridge case, but this requires the use of various types of light beam emitting units, which increases the manufacturing cost and is also difficult for the user. Purchase cost increases. So, make a light beam firing unit to fit a small size shotgun,
For a large-sized shotgun, an attachment to be attached to the light beam emitting unit may be prepared according to the specifications of the shotgun chamber. FIG. 4 shows an example of this attachment, in which an attachment 35 capable of accommodating almost the entire light beam emitting unit 6 is used. The rear end of the attachment 35 is open, and the light beam emitting unit 6 can be inserted from the open rear end. There is a step on the inner periphery of the front end of the attachment 35, and when the front end of the light beam emitting unit 6 hits this step, the light beam emitting unit 6 is positioned and stored in the attachment 35. At the front end of the attachment 35, there is a window 36, and the laser beam emitted from the semiconductor laser chip 10 is emitted from the window 36.

The light beam emitting unit 6 is stored in the attachment 35 in the shotgun chambers 4 and 5 instead of the cartridge case as described with reference to FIG. Therefore, when the attachment 35 is loaded in the medicine chambers 4 and 5 together with the light beam emitting unit 6, the optical axis of the laser beam emitted from the light beam emitting unit 6 is aligned with the center axis of the barrels 2 and 3. The external and internal shapes of the attachment 35 are finished with high dimensional accuracy.

In the above embodiment, the light beam emitting unit is used for aiming practice, but as shown in FIG.
5, the center of the rear end is knocked by the firing pins 12 and 13 when the triggers 8 and 9 are pulled to perform the blank hitting practice. Therefore, it is desirable to reinforce the portion where the firing pin contacts by increasing the plate thickness or adding a high hardness receiving plate. In the example shown in FIG. 2 and FIG.
The bottom of 1 is thickened and reinforced.

In each of the embodiments described above, a semiconductor laser is used as a light source and a laser beam is emitted as a light beam. However, the light source is not limited to a laser light source. LE
D), a discharge lamp or the like may be used. However, a laser is suitable for the present invention because of its good convergence, and among various laser light sources, a semiconductor laser that operates at low power and emits red light that is easily visible can be said to be suitable for the present invention. . The outer shape of the light beam emitting unit does not necessarily have to be the same as the outer shape of the cartridge case loaded in the shotgun, and may be, for example, longer than the cartridge case.
However, the outer shape of the light beam emitting unit is formed in accordance with the inner shape of the barrel so that the light beam emitting unit does not rattle inside the barrel when the light beam emitting unit is loaded. In short, it is only necessary that the optical axis of the light beam be aligned with the center axis of the barrel and be loaded into the shotgun.

The cylinder 6 which forms the main body of the light beam emitting unit
The cylinders 1 and 62 or the cylinders 71 and 72 do not necessarily need to be made of a conductive material, and may be, for example, an integrally molded product of plastic. In this case, electrical continuity can be ensured by insert molding the conductor. Further, the type of switch for turning on and off the operation of the light source is also optional.For example, a cylinder forming the main body of the light beam emitting unit is divided into two parts in the length direction so as to be relatively rotatable around the central axis, and the relative rotation is performed. It may be turned on at one end in the direction and turned off at the other end. Also, a push switch is provided on the light beam emitting unit and its operation button is projected from the outer peripheral surface of the light beam emitting unit main body. When the light beam emitting unit is loaded on the shotgun, the operation button is placed on the inner wall of the loading chamber. Is pressed, the push switch is turned on, and the light source operates to emit a light beam.

The shotgun loaded with the aiming training tool according to the present invention is not limited to the upper and lower dual type as shown in FIG. 1, but may be a single shot type or a horizontal double type. In the case of a double gun, when the aiming training tool according to the present invention is mounted on each barrel and a light beam is emitted, each light beam crosses at a cross point of the center axis of each barrel. It can be confirmed without firing cross points. When the aiming training tool according to the present invention is used, even when the attitude of holding the gun is out of order, it can be easily visually confirmed that the position of the light beam spot is out of order. By using the aiming practice tool according to the present invention, aiming practice can be performed on a moving target without actually firing, for example, by substituting a balloon filled with helium gas for the target. Further, according to the present invention, since there is no need to perform actual shooting, aiming training can be performed at low cost. When the aiming training tool according to the present invention is formed in the same shape as the outer shape of the cartridge case, the color of the surface of the aiming training device is completely different from that of the cartridge case so as to be clearly distinguished from the cartridge case in which the live ammunition is inserted. , Or transparent.
