Description

Optical Sight

The present invention relates to an optical sight.

In general, aiming of a rifle is made by aligning the sight line between the scale and the sight, and the aiming by alignment of the line of sight between the sight located at the tip of the barrel and the scale located on the upper part of the gun body is determined by the skill of the user using the firearm. This allows for accurate shooting.

However, there are disadvantages in that it is difficult to align the aiming line even with small vibrations or vibrations, and it is disadvantageous to a quick aim required in a short distance or an urgent situation.

That is, in this aiming and shooting method, a complex process and time such as target capture and confirmation, reticle alignment, and aiming are required, and since the sight and scale themselves are very small, they not only respond sensitively to small vibrations in aligning them accurately, but also If you pay too much attention to the line of sight alignment, your eyes will be focused on the sight and the scale itself rather than the target or the situation ahead, and your field of vision will be narrowed.

An optical sight has been proposed to improve the accuracy while solving the trouble of alignment of the line of sight as described above, but in the case of the conventional optical sight, since a telephoto lens is used, as the magnification increases, it responds sensitively to small vibrations as well. Accordingly, the problem of not being able to aim quickly remained.

In order to solve the above problems, a dot sight device has been proposed that employs a no-magnification (low magnification) lens in an optical sight, and uses only an aiming point while eliminating a complicated aiming line.

The dot sight device is characterized in that simple and quick aiming is possible, and it is very useful in an urgent situation or close range requiring a quick response.

In other words, almost no time is required to align the aiming line, and the aiming itself needs to move the light point to the target quickly, and because the sight is secured very effectively, not only the aiming time, but also the peripheral vision and There is an advantage in that the interruption of situation confirmation can be reduced to a minimum.

The conventional aiming method using the dot sight as described above is useful only for shooting at a known distance (distance known to the shooter) because there is no means to measure the distance to the target. can be vulnerable

When describing a method of using mis-aim, as shown in FIG. 5 , shooting through mis-aim may be possible using the vertical part 314 of the cross. Specifically, if the cross mode of 30 MOA (that is, the distance between the vertical parts 314 is 210 mm), the distance to the target is 400 m, and the personalizer equipped with an optical sight is the K2, it is 10 clicks under the ballistic correction factor table. In the optical sight according to the embodiment of the present invention, the distance from the dot to the vertical part 314 of the cross without correction corresponds to 105mm (in the case of 30MOA, the distance between the vertical parts is 210mm) and 1 click Considering that the 3.5mm moves, it is possible to shoot with a false aim to a point about 1/3 between the dot and the vertical part of the cross.

The user may estimate the distance to the target by measuring the size of the target within the circle 322 using the circle 322 in the third reticle 320 . That is, when a target within the circle 322, for example, a person is larger than the circle 322, the distance can be estimated as 200 m or less, and when it is smaller than the circle, the distance can be estimated between 200 and 500 m.

In addition, when the user performs shooting using the third reticle 320, the target inside the circle 322, for example, when a person is larger than the circle, measures the distance to 200 m or less and aligns the head on the top of the circle 322. If the person is smaller than the circle 322 , the distance to the target is measured to be between 200 and 500 m, and the person's foot is positioned at the lower end of the circle 322 , so that the user can shoot with a false aim. However, if the target person is 1/3 the size of the circle, the distance to the target can be estimated as 600m, and the target can be aligned at the bottom of the vertical part 314 of the cross to shoot.
