[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ballistic adjustment aid used when aligning the center of a reticle, which is visible when looking into a scope, with the direction of the barrel.

[0002]

[Prior art]

A pistol such as a rifle or an air rifle is usually provided with a scope. With such a pistol, the shooter looks into the scope and shoots at the center of the reticle reticle visible in the scope, at the target. At this time, if the center of the reticle and the direction of the barrel are completely aligned, the target located at the center of the reticle can be accurately shot.

However, if the center of the reticle and the direction of the barrel are misaligned, even if the shooting target is aligned with the center of the reticle, the shooting target cannot be shot accurately. Conventionally, the deviation between the center of the reticle and the direction of the barrel is adjusted (corrected) by the following method.

That is, conventionally, the shooter looks into the scope and actually shoots by aligning the center of the reticle with a predetermined shooting target. Then, confirm the deviation between the shooting target aligned with the center of the reticle and the actual shooting position, and adjust the center position of the reticle of the scoop based on this deviation. This adjustment is performed, for example, by rotating an adjusting screw provided on the scope and moving the reticle vertically and horizontally according to the rotation. Specifically, if the actual shooting position is displaced to the right, for example, from the position of the shooting target aligned with the center of the reticle, rotate the adjusting screw by the amount corresponding to the displacement distance, Move the center of the reticle to the right.

[0006]

[Problems to be solved by the device]

 However, the adjustment method described above requires several trial shots in order to adjust the reticle, which requires a long adjustment time and a high cost. In addition, it is usually necessary to check the deviation between the actual shooting position and the position set at the center of the reticle every time a trial shot is made, which makes the adjustment operation complicated. As a result, adjustments were sometimes not accurate.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a ballistic adjustment assisting tool that can perform ballistic adjustment accurately in a short time, and easily.

【Example】

 Hereinafter, a trajectory adjusting aid according to an embodiment of the present invention will be described in detail with reference to the drawings. The first embodiment will be described. 1 is an external view of the ballistic adjustment assisting tool 1 of the present embodiment when it is fitted into the barrel of a handgun 2, FIG. 2 is an exploded perspective view of the ballistic adjustment assisting tool 1 shown in FIG. 1, and FIG. 3 is the trajectory shown in FIG. 4 is a cross-sectional view of the shaft 10 shown in FIG. 3, FIG. 5A is a perspective view of the scope 3 shown in FIG. 1, and FIG. 3] is a view for explaining a reticle 3d appearing in a visual observation portion 3a of the scope 3 shown in FIG.

First, the trajectory adjusting aid 1 will be described. As shown in FIGS. 1 and 3, the trajectory adjusting aid 1 is attached to the barrel through a muzzle 2a of a gun 2. As shown in FIG. 2, the ballistic adjustment aid 1 has a shaft 10, a battery 11, a case 12 and a light emitting part 13.

The shaft 10 is made of, for example, a conductive member having a predetermined rigidity, and has a shaft body 10a, an engaging portion 10b, and a screw portion 10c. The shaft body 10a has a circular cross section with an outer diameter slightly smaller than the inner diameter of the barrel, and as shown in FIGS. 2, 3, and 4, the O-ring 10e is provided at two predetermined positions along the longitudinal direction. A groove 10d for mounting is formed. The O-ring 10e is made of an elastic member such as rubber and has an inner diameter that can be stably mounted in the groove 10a of the shaft body 10a and an outer diameter that is slightly larger than the inner diameter of the barrel when mounted in the groove 10a. Have.

When the shaft body 10a equipped with such an O-ring 10e is fitted into the barrel, the O-ring 10e and the inner wall of the barrel are brought into close contact with each other while the O-ring 10e is contracted by the inner wall of the barrel, and the shaft body 10a is attached to the barrel. It is fixed stably. Further, by providing the O-ring 10e which is an elastic member, it is possible to prevent the shaft main body 10a having a higher rigidity than the O-ring 10e and the inner wall of the barrel from being strongly rubbed and being scratched. Also, the elasticity of the O-ring 10e allows flexibility in the fitting between the shaft body 10a and the barrel, and even if the barrel is worn down a lot due to the friction caused by shooting, Can be inserted stably. Furthermore, the influence of the manufacturing error on the shaft body 10a can be reduced.

The screw portion 10c has a screw groove that can be screwed into the screw groove formed in the case 12. The engaging portion 10b has, for example, the same outer diameter as the outer diameter of the case 12, and when the screw portion 10c is screwed into and fixed to the case 12, the side wall thereof engages with the thick portion of the case 12. .

As the battery 11, for example, a 1.5V alkaline dry battery is used.

The case 12 is made of, for example, metal and has a region for storing the two batteries 11 in series, and a screw groove for screwing the screw portion 10c of the shaft 10 is formed at one end of this region. Has been done. In addition, the case 12 is a negative terminal electrically connected to the negative electrode of the battery 11 in the state where the battery 11 is connected in series and stored and the shaft 10 is mounted, and the engaging portion 10b of the shaft 10 or the screw. It is electrically connected to the portion 10c and has a built-in positive terminal.

The light emitting unit 13 has a semiconductor laser 13a that is operated by a voltage supplied from the positive and negative terminals of the case 12, and an optical system such as a lens that converges the laser light emitted from the semiconductor laser 13a. When the shaft 10 is mounted on the barrel, the emitting direction of the laser light from the light emitting unit 13 coincides with the barrel direction. The laser light emitted from the light emitting unit 13 is, for example, red and diffuses into a light beam having a diameter of about 10 cm at a distance of 100 m, for example. The light intensity of the laser light emitted from the light emitting unit 13 is determined according to the shooting distance of the pistol 2 and the like.

The ballistic adjusting aid 1 stores two batteries 11 in a case 12, and when the shaft 10 is attached to the case 12, the voltage from the battery 11 is supplied to the light emitting unit 13 and the light emitting unit 13 is supplied. Emits laser light.

Next, the scope 3 will be described. As shown in FIG. 1, the scope 3 is fixedly attached to the upper part of the pistol 2. The shooter views the cross-shaped reticle 3d shown in FIG. 5 (B) together with the outside scenery from the viewing portion 3a of the scope 3 shown in FIG. 5 (A). The reticle 3d moves left and right when the shooter rotates the adjustment unit 3c of the scope 3 shown in FIG. 5A, and moves vertically when the adjustment unit 3b rotates. When the shooter adjusts the direction of the barrel and the intersection of the reticle 3d to coincide with each other, the shooter rotates the adjusting units 3b and 3c by a driving force to move the reticle 3d vertically and horizontally.

Next, a method of performing trajectory adjustment using the trajectory adjustment aid 1 will be described. First, the shooter inserts the shaft body 10a of the shaft 10 of the trajectory adjusting aid 1 into the barrel through the muzzle 2a, as shown in FIG. When the shaft body 10a is fitted into the barrel, the O-ring 10e is brought into close contact with the inner wall of the barrel, and is fixed to the barrel in a stable state. The trajectory adjusting aid 1 attached to the barrel of the pistol 2 emits a laser beam from the light emitting section 13 in the barrel direction. At this time, theoretically, the emitting direction of the laser light coincides with the shooting direction. Then, the shooter holds the pistol 2 by hand and irradiates a predetermined object with the laser light from the light emitting unit 13. Then, the shooter visually checks the laser light radiated to the object through the visual observation part 3a of the scope 3, and the irradiation point of this laser light and the visual observation part 3a shown in FIG. 5 (B). The adjustment parts 3b and 3c shown in FIG. 5A are rotated so that the intersection 3d1 of the reticle 3d coincides with the reticle 3d.

At this time, for example, before the adjustment, as shown in FIG. 6 (A), when the irradiation point 15 is visually observed in the direction of 2 o'clock with respect to the intersection 3d1, the shooter is required to adjust the adjustment unit 3b, 3c is rotated so that the irradiation point 15 and the intersection 3d1 coincide with each other as shown in FIG. 5 (B). Such an operation can be continuously performed because the laser light is continuously emitted, and the accuracy of adjustment can be improved. As a result, the object located in the barrel direction can be located at the intersection 3d1 of the reticle 3d. As a result, by using the scope 3 adjusted in this way, if the shooter shoots at the intersection 3d1 of the reticle 3d that is visually recognized through the viewing section 3a, the shooting target can be accurately shot. it can.

At this time, when the irradiation point 15 is visually recognized as a circle having a predetermined inner diameter due to light diffusion, the reticle 3d is moved so that the center point of the circle coincides with the intersection point 3d1. Good.

As described above, according to the trajectory adjusting aid of the present invention, the reticle can be adjusted without performing a trial shot. Therefore, the adjustment operation can be performed easily and in a short time, and the adjustment can be easily performed accurately. Also, since no live ammunition is used, the cost associated with adjustment can be reduced.

The ballistic adjustment assisting tool 1 of the present embodiment is not limited to the above-described embodiment, and for example, a shaft body as shown below may be used instead of the shaft body 10a shown in FIG. FIG. 7 shows a modified example of the shaft body used in the trajectory adjusting aid 1. As shown in FIG. 7, in the shaft main body 21 of the present modification, three grooves 21b are formed at positions alternately facing each other along the longitudinal direction. One end of the wire 21c is fixed to the groove 31b. The other end of the wire 21c is free, and when the shaft body 21 is not fitted in the barrel, it projects from the surface of the shaft body 21 as shown in FIG. When the shaft body 21 is fitted into the barrel, the other end of the wire 21c is pressed by the inner wall of the barrel and is housed inside the groove 21b. At this time, the wire 21c presses the inner wall of the barrel by its restoring force, and the shaft main body 21 is stably fixed to the barrel by the frictional force generated between the other end of the wire 21c and the inner wall of the barrel.

FIG. 8 shows another modification of the shaft body used in the trajectory adjusting aid 1. As shown in FIG. 8, the shaft body 20 according to this modification has grooves 20d formed at two locations along the longitudinal direction. One end of the wire 10c is fixed to the surface of the shaft body 20 and the other end is fixed to the moving portion 20b located on the surface of the shaft body 20. When the shaft body 20 is fitted into the barrel, the wire 20c is pressed against the barrel by the inner wall, and the moving portion 20b moves into the groove 20d by the pressing force. At this time, the wire 20c presses the inner wall of the barrel by its restoring force, and the shaft body 20 is stably fixed to the barrel by the frictional force generated between the wire 20c and the inner wall of the barrel.

Further, in the above-described embodiment, the case where the elastic member is provided on the shaft body has been described as an example, but the shaft body without the elastic member may be directly fitted into the barrel.

A second embodiment will be described. FIG. 9 is an external view of the ballistic adjustment assisting tool 31 of this embodiment mounted on the pistol 32. In this embodiment, a mounting portion 33 for mounting the ballistic adjusting aid 31 is fixedly provided below the muzzle 32a of the pistol 32. The mounting portion 33 is formed with a screw hole that can be mounted while screwing one end of the case 31. The trajectory adjusting aid 31 mainly includes a case 31a and a light emitting section 31c provided at one end of the case 31a. The case 31a is basically the same as the case 12 shown in FIG. 2 described above, and is provided with a light emitting portion 31c at one end and a thread groove 31b capable of being screwed into the mounting portion 33 of the pistol 32 at the other end. Has been done. When the ballistic adjustment aid 31 of this embodiment is attached to the pistol 32, the direction in which the laser light is emitted from the light emitting portion 31c and the barrel direction are substantially the same.

Therefore, also with the trajectory adjusting aid 31 of this embodiment, the same effect as in the case of the first embodiment described above can be obtained.

Further, according to the trajectory adjusting aid 31 of the present embodiment, when mounting on pistols having various calibers, the mounting portion 33 provided for each pistol is made common, so that a single bullet is mounted. The road adjusting aid 31 can be attached to a pistol having a plurality of calibers. Further, according to the trajectory adjusting aid 31 of the present embodiment, since the shaft body is not fitted into the barrel, the possibility of scratching the barrel can be reduced.
