Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sighting telescope that is attached to a rifle used mainly for hunting.

(Prior art) Conventionally, for example, there are reticles specifically for deer, trajectory correction devices for specific guns, and trajectory correction devices for specific gun and bullet combinations, but these are not versatile and require a built-in special reticle. It also had the disadvantage of requiring a special trajectory correction device to be installed.

(Technical line @) Therefore, the present invention is capable of measuring the distance to an object by looking through a sighting telescope, and even when various conditions such as any gun, any bullet, any animal, etc. The technical challenge is to be able to correct the trajectory of a gun that meets these conditions.

(Technical Means) In order to solve the above-mentioned technical problem, the present invention uses a scale arranged on the first reticle member to know the distance to the target object, and corrects the trajectory drop corresponding to the known distance. A trajectory correction device is attached to the lens barrel to improve aiming accuracy.

Specifically, as shown in the illustrated embodiment, the configuration is as follows.

(a) Regarding the iql determination of the distance to the target object by the M-reticle member.

l is the telescope tube, which mainly consists of objective lens 2 and eyepiece lens 3.
It is composed of a first reticle member 4, an electric tube 5, a second reticle member 6, and two trajectory correction devices 7 arranged 90 degrees apart.

The first reticle member 4 is made of glass and is held in a first reticle member holding cylinder 8. The base 9 of the first reticle member holding cylinder 8 is pivotally supported by a support member 10, and the other end 11 is supported by a first reticle member holding cylinder 8. It is in contact with one reticle member adjusting screw 12 and 12A. Note that the first reticle member 4 may be made of a known metal frame (commonly known as a metal panel) instead of being made of glass.

By operating this first reticle member adjusting screw 12, the first reticle member is held fii! Y8 will be tilted in the directions of arrows A and B using the support member 10 as a fulcrum.

As shown in FIG. 2, 13 and 14 are distance measuring vertical scales placed on the upper half of the first reticle member 4, and intersect with each other in a cross shape. The distance measuring vertical scale 13 and the distance measuring vertical scale 14 are positioned at the focal point of the objective lens 2.

By reading the scale value of either the distance horizontal scale 13 or the distance vertical scale 14, the distance to the target object, such as the animal, can be known.

The horizontal distance scale 13 and the vertical distance scale 14f'i are graduated according to the following relationship.

Generally, as shown in FIGS. 4 and 5, the distance can be determined by knowing the average trunk length or average trunk thickness T of the animal 15.

Specifically speaking, the horizontal distance scale 13 and the vertical distance scale 14
is a scale in which one division corresponds to a distance of 100 yards (91 m) and the size corresponds to 1 inch (2.54 cm).

Therefore, the distance can be determined by how many scale marks the length or thickness T of the torso of the animal 15 reflected on the first reticle member 4 appears.

Table 1 shows the relationship between the average trunk thickness T of the target animal and the length or thickness of the animal 16 corresponding to the distance.

Referring to the example in Table 1, the large dust animal 15 now reflected on the first reticle member 4
When visually reading that the body thickness T is 12 scales on the distance vertical scale 14, it is understood that the distance is 200 yards (about 182 m).

This table is useful for hunters to carry with them at all times. P is a part of the cross center.

(for production) (a) Regarding trajectory correction effect.

The telescope tubes are attached to a gun (not shown), and then the gun is fixed individually to a base (not shown). and [1
Fire one test shot at a target at a distance of 100 yards.

At this time, the impact point R appears on the first reticle member 4 as shown in FIG.

Next, the first reticle member adjustment screws 12 and 12A are operated appropriately to align the cross center portion P of the first reticle member 4 with the impact point R of the test shot described above. (See FIG. 10) That is, by operating the first reticle member adjustment screws 12 and 12A, the first reticle member holding cylinder 8 is deflected about the support member 10 as a support shaft.

Now that the first reticle member 4 has been set,
This set position is fixed with a set screw (not shown) for fixing the first reticle member so that it does not shift on the @ board.

Next, the cap retainer 24 of one trajectory correction device frt7 is loosened, the cap 23 is removed, and a screwdriver or the like is inserted into the groove 42A of the connecting shaft member 40 to rotate the connecting shaft member 40.

The other trajectory correction device 7A, which is disposed at a deviated angle of 90°, is operated in the same manner as described above, and the cross center portion Q of the second reticle member 6 is aligned with the cross center portion P of the first reticle member 4. It is something that makes them match.

Specifically, in order to align the cross center portion Q of the thin aiming line 18 as shown in FIG. 11 with the cross center portion P of the first reticle member 4 as shown in FIG.
When the actuator 51 is rotated appropriately via the split R42A, the actuator 51 is regulated by the rotation stopper screw 50 and the thread 55 and the thread 56t-
move vertically through the

Therefore, the lower end 54 of the actuator 51 presses the other end 22 of the erector tube 6, deflecting the erector tube 5 in the direction of arrow C or D using the support member 20 as a fulcrum, and the telescope An immovable second reticle member 6 fixed to the tube 1
The cross center portion Q of the thin aiming wire 18 is optically aligned with the cross center portion P (Table 6).Next, the cap 23 is fitted and rotated appropriately to ensure that the cap rotation stopper 33 is aligned with the cross center portion P. Rotate it to the right until it collides with the stopper 34 of the index plate holder 28. After that, by tightening the cap stopper 24, the cap stopper 24, the cap 23, and the connecting shaft member 40 become integral.

Therefore, since the cross center part P of the first reticle member 4 and the cross center part Q of the thin aiming line 18 of the second reticle member 6 are aligned with the impact point R of the test shot at a distance of 100 yards, the distance is 100 yards. Loosen the distance ring fixing screw 39 of the yardage distance ring 35A and rotate the distance ring 35A appropriately to align the index 57 with the index 31 of the index plate 30.

Next, the distance ring fixing screw 39 is tightened to fix the distance ring 35A to the cap 23.

This means that trajectory correction for a distance of 1110 yards has been completed.

Next, trajectory correction for a distance of 200 yards is performed without actually firing, with reference to Table 2.

Specifically, when the cap 23 of the trajectory correction device 7 is rotated to the left, the connecting shaft member 40. Operator 51, erector
Via the tube 5, the horizontal aiming line 18A of the second reticle member 6 moves vertically downward, ie, in the direction of the arrow E, with respect to the cross center portion P of the first reticle member 4, as shown in FIG.

Therefore, from Table 2, since the MOA value for a trajectory drop at a distance of 200 yards is "1", the horizontal direction of the second reticle member 6 is adjusted by one scale of the trajectory drop correction scale 16 on the first reticle member 4. Move the aiming thin line 18A in the direction of arrow E.

Next, the distance ring fixing screw 39 of the distance ring 35B for a distance of 200 yards is loosened, and the distance ring 35B is appropriately rotated to align the index 67 with the index 31 of the index plate 30.

Next, the distance ring fixing screw 39 is tightened to fix the distance ring 35B to the cap 2317C.

This means that trajectory correction for a distance of 200 yards has been completed.

If you want to further correct the trajectory for distances from 300 yards to 800 yards, use the same procedure as for the correction for the distance 200 yards, and use each distance ring 35C to 35Hf one by one, referring to Table 2. Just operate it. (b) How to actually use it (-example).

It is assumed that trajectory correction has already been completed.

Now, if the large door animal 16 is reflected on the first reticle member 14 and the body thickness T is 12 inches (approximately 30 inches) on the distance line scale 14, then the distance is 200 yards (approximately 1822
From Table 1, it can be seen that F+).

Therefore, next, the cap 23 is rotated in a predetermined direction, and the index 67 of the distance display number r200J is placed on the distance ring 35B for 20 bonito which is integrated with the cap 23.
is aligned with the index 31 on the index board 30.

At that time, the cross center portion Q is at position 1iQzoo (Figure 14).

If the animal 15 is centered at this position Q2oo and shot, the bullet will hit the animal 15 at a distance of 200 yards.

(Effects) Therefore, the present invention has the following unique effects: (a) It is possible to measure the distance to the target object, and it is extremely easy to correct the impeachment drop of the gun for the measured distance. It can quickly respond to changing conditions such as any gun, any bullet, any animal, etc.

(b) Speedy and accurate shooting became possible in a short amount of time.

(C1 ballistic drop correction only needs to be fired once.
