Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sighting device for a gun, and more particularly to a sighting device that can easily aim when shooting with a belly crawling (also referred to as prone shooting).

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional gun sighting device is attached to a gun 101, and a shooter 109 moves a sighting line 105 from a sighting device 103 to a target (not shown).
Aiming with a line of sight along a straight line 107 containing
He was shooting. The aiming device 103 includes a front sight 103b and a rear sight 103a. The front sight 103b determines a target direction when aiming at the rear sight 103a (for example, a target position is indicated by a small circle), and the rear sight 103a is viewed by the shooter 109. Can be aimed at.

[0003]

However, when shooting is performed using the gun 101 to which the aiming device 103 shown in FIG. 7 is attached, when the shooter 109 stands up (not shown), the shooter 109 naturally Can be fired in a posture close to a standing posture (the neck 111 of the shooter 109 is close to a natural standing state), but as shown in FIG. In (2), the shooter 109 is forced to bend the neck 111 upward at an acute angle, and the neck 111 of the shooter 109 and its surroundings (for example, shoulders) are greatly fatigued. Further, such a posture in which the neck 111 is bent upward at a sharp angle not only increases the fatigue, but also forces the shooter 109 to be in a cramped posture, lowering the concentration power and reducing the accuracy of aiming. There was also a problem.

Therefore, in the present invention, as shown in FIG. 7, even when the shooter 109 shoots in a stomach crawling state, the shooter 109 is forced to bend the neck 111 upward at a steep angle. The aim is to provide an aiming device without any. By using such an aiming device, fatigue of the shooter 109 due to shooting in a stomach crawling state is significantly reduced, and accurate aiming for a long time in a stomach crawling state is enabled.

[0005]

An aiming device for a gun according to the present invention (hereinafter referred to as "the present device") is viewed from a direction forming a predetermined angle with respect to a straight line including an aiming line from an aiming device to a target. Aiming device that can aim. Here, the “predetermined angle” refers to an angle described below.
First, a straight line including a line of sight from the aiming device to the target (hereinafter, referred to as a "line of sight") and a line including a line of sight for aiming the shooter (hereinafter, referred to as a "line of sight").
And think. At this time, if the aiming line and the line-of-sight line do not belong to the same plane, the line-of-sight line is moved in parallel so that the line-of-sight line belongs to any plane including the line-of-sight line (hereinafter referred to as “sighting plane”). The line of sight moved so as to belong to the plane is defined as a moving line of sight. On the other hand, when the aiming line and the line of sight belong to the same plane, the line of sight is regarded as the moving line of sight (that is, when the line of sight and the line of sight do not belong to the same plane, the line of sight is moved to belong to the aiming plane). The line of sight is defined as a moving line of sight, and when the aiming line and the line of sight belong to the same plane, the line of sight is defined as a moving line of sight.) The angle formed at the intersection of the aiming line and the moving line-of-sight line in the aiming plane (a line segment belonging to the moving line-of-sight line from the eye side of the shooter to the intersection, and belonging to the reference line and having the intersection as an end point The angle formed by a half-line extending on the opposite side to the object and at an angle of 0 ° or more and less than 180 °) is the “predetermined angle”. The “predetermined angle” means that the angle formed at the intersection of the aiming line and the moving line-of-sight line in the aiming plane is sufficient if it is greater than 0 ° and less than 180 °, but it is usually determined by shooting in a crawling state. Considering the position of the shooter, preferably 20
Degrees or more, more preferably 30 degrees or more, most preferably 40 degrees or more, while preferably 90 degrees or less, more preferably 80 degrees or less, and most preferably 70 degrees or less. . By doing so, it is possible to peep from a direction that forms a predetermined angle with respect to the aiming line, and aim can be adjusted, so when the shooter shoots in a stomach crawling state,
By aiming from above the line of sight and aiming (pointing the direction at an angle above the line of sight), the shooter is not forced to bend his head upward at a sharp angle. You can aim and fire. By using such a device, fatigue of a shooter due to shooting in a stomach crawling state is greatly reduced, and accurate aiming for a long time in a stomach crawling state is enabled. If the reference straight line and the line-of-sight straight line belong to the same plane, the present apparatus can be made compact, which is preferable.

[0006] The image processing apparatus may further comprise a reflecting means for reflecting an image of the target incident from a direction along the line of sight in the direction forming the predetermined angle. By using the reflecting means in this way, the present apparatus can be configured at a low cost, and even an image of a target that is distant or not bright can be reflected in the direction forming the predetermined angle well, and You can look in and aim. The reflecting means may be any one that reflects the image of the target in the direction forming the predetermined angle to the extent that the aiming can be performed, and is not particularly limited. A prism or a mirror surface may be used because light attenuation due to light is small and a reflected image is easily obtained. Note that a pentagonal prism or the like may be used as the prism.

[0007] The reflecting means may reflect the image even number of times. Each time the reflecting means reflects the image of the target once, the image of the target reverses.
If the light is reflected an odd number of times, the image at the time of aiming is an inverted image (upside down, left and right are reversed), and it is difficult to grasp the actual situation. For this reason, if the reflecting means reflects the image of the target object two times, four times, six times,..., An even number of times, the image at the time of aiming is a normal image (upside down, left and right are not reversed). This is preferable because the actual situation can be easily grasped.

The direction forming the predetermined angle may be rotatable within a predetermined range around a straight line (reference straight line) including the aiming line. In this way, the direction in which the user looks in for aiming (that is, the direction forming the predetermined angle) can be rotated within a predetermined range around the line of sight, so that the aiming can be performed in accordance with the position of the shooter when shooting. Can be rotated to a position where it can be easily adjusted. For this reason, when the shooter shoots in a stomach crawling state, the aim can be adjusted in a more comfortable posture, further reducing the fatigue of the shooter due to the shooting in the stomach crawling state, and more accurate for a long time in the stomach crawling state Enables aiming.

The type of gun to which the apparatus is attached is not particularly limited, and can be used by attaching to various guns. Especially when mounted on a competitive rifle that competes for accuracy when shooting when the shooter is crawling, even if the shooter fires while crawling, the shooter bends the neck upwards at a sharp angle This makes it possible to significantly reduce the fatigue of the shooter due to shooting in a stomach crawling state, and to achieve accurate aiming in a stomach crawling state. This precise aiming can also be performed over a long period of time, since it significantly reduces the fatigue of the shooter due to shooting while lying on the stomach.

For this reason, even when the shooter is crawling, the shooter can shoot without being forced to bend his head upward at a steep angle, so that the shooter is generated at the shooter's neck and its surroundings (eg, shoulders). In addition to significantly reducing fatigue, the accuracy of aiming can be significantly improved.

Although the sighting device has a front sight and a rear sight here, the present invention is not limited to this.
a and the second shaft adjusting screw 25b are not essential. In the above embodiment, only the reference straight line and the line of sight belong to the same plane. However, the present invention is not limited to this, and the reference line and the line of sight do not belong to the same plane ( That is, the position may be a twist). At this time, for example, assuming that the reference straight line belongs to one of the two parallel planes and the line of sight belongs to the other plane, the first perpendicular line is lowered from one point M on the reference straight line to the other plane. When the foot of the perpendicular line is point N, the second perpendicular line is lowered from the point N to the line of sight in the other plane, and the foot of the second perpendicular line is point P, in the direction from point M to point N A first mirror surface disposed at a point M for reflecting an image, a second mirror surface disposed at a point N for reflecting an image in a direction from the point N to the point P, and a line of sight from the point P And a third mirror surface disposed at a point P that reflects the image in the direction toward the eyes. However, even in such a case, an odd number of sheets (1
, Three, five,...) May be appropriately disposed.
