JPS5810725B2 - Zoom rifle scope with distance measuring device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a zoom rifle scope equipped with a distance measuring device capable of measuring the distance from a hunter to a target.

Conventional riflescopes were not equipped with a distance measuring device, so the distance to the target had to be measured visually, which had the disadvantage that the distance scale of the trajectory correction device could not be set accurately.

The present invention improves the above-mentioned drawbacks by providing a rifle scope with a distance measuring device.

Next, referring to the drawings, in the present invention, a scale ring 2 with a transparent distance scale 1 displayed on the side surface is integrally attached to one end of a variable magnification ring 3, and a cross-shaped reticle 5a is attached to a scale ring 5 installed in the main body 4. , 5b and a scale line 7 parallel to the horizontal line 6a of the reticle to determine the height of the target T at a certain distance as seen through the lens when the magnification of the zoom rifle scope is set to the lowest magnification. is made to match the distance l between the horizontal line of the reticle and the scale line, and the distance scale of the scale ring is set on the refracting prism 8.
This is a zoom riflescope equipped with a distance measuring device that can be seen from inside the sight ring 9 through the lens.

In the figure, 10 is a trajectory correction device, 11 is a trajectory correction distance scale, 12 is an aperture, and 13 is a rifle.

Next, an embodiment of the present invention will be described. The minimum magnification of the zoom rifle scope is 3x, and the height of the deer seen through the lens of an average-sized target (for example, a deer) located 100 yards ahead is (if the fuselage height) is the cross-shaped reticle 6a,

If the horizontal line 6a of 6b and the scale line 7 are set to match the gap l, if the target is located 200 yards ahead and the zoom riflescope is at its lowest magnification, its height will be 2 of the gap l. This means that it can be visually recognized at one-fold the height.

Therefore, when the magnification of the riflescope is changed to 6x (2x at the lowest magnification) by rotating the variable magnification ring 3 provided on the circumference of the main body 4, the height mentioned above becomes the height visually recognized at the lowest magnification. 2
Since it is doubled, it matches the gap l.

Here, the variable magnification ring 3 and the scale ring 2 are provided integrally, and the magnification scale and the distance scale correspond to each other in proportion, so when the magnification scale of the variable magnification ring indicates 6x, the distance of the scale ring The scale indicates 200 yards, and the value is visible from inside the viewing ring 9 through the refracting prism 8 (see FIG. 5).

Then, when the trajectory correction distance scale 11 of the trajectory correction device 10 is made to match the above numerical value (see the third number), the accurate distance from the hunter to the target is set in the trajectory correction device (see FIG. 2).

In addition, the minimum magnification of the rifle scope, the distance to the target that matches the gap l, the height of the target, etc. can be selected as appropriate in advance, and when the values are determined, they are set as the basic values on the rifle scope. .

The distance scale 1 is made up of transparent letters that transmit light on a black background, and since a fenestration 12 is formed above the scale ring 2, the numbers on the distance scale are extremely easy to read. .

Therefore, the present invention has an excellent effect in that the distance between the hunter and the target can be accurately determined simply by matching the height of the target to the gap l.

Furthermore, since the distance to the target is known, the amount of fall of the trajectory can be easily known, and an accurate value can be set on the distance scale of the trajectory correction device that stores the amount of fall, so the reticle It has an excellent feature that if the intersection of the two and the target coincide with each other, the trajectory of the bullet will intersect with the target, and the accuracy of the rifle 13 will be significantly improved.
