[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a sighting telescope that is attached to a rifle used mainly for hunting and the like. (Prior Art) Conventionally, for example, there are reticles specifically for deer, trajectory correction devices for specific guns, and trajectory correction devices for combinations of specific guns and bullets.
The disadvantages were that it was not versatile and required a special built-in reticle and a special trajectory correction device. (Technical Problem) Therefore, the present invention makes it possible to measure the distance to the target by looking through a sighting telescope, and even if the conditions change, such as what kind of gun, what kind of bullet, what kind of animal, etc., the distance to the target can be measured. The technical challenge is to be able to correct the trajectory of a gun that has (Technical Means) In order to solve the above-mentioned technical problem, in the present invention, the distance to the target object is known from the scale arranged on the first reticle member, and the mirror is used to correct the trajectory drop corresponding to the known distance. A trajectory correction device is attached to the barrel to improve aiming accuracy. Specifically, as shown in the illustrated embodiment, the configuration is as follows. (a) Regarding measuring the distance to the target object using the first reticle member. Reference numeral 1 denotes a telescope tube, which is mainly composed of an objective lens 2, an eyepiece lens 3, a first reticle member 4, an erector tube 5, a second reticle member 6, and two ballistic correction devices 7 arranged at 90° apart. be. The first reticle member 4 is made of glass and is held by a first reticle member holding cylinder 8, and the base 9 of the first reticle member holding cylinder 8 is connected to a support member 10.
The other end 11 is in contact with the first reticle member adjustment screws 12 and 12A. still,
The first reticle member 4 may be made of a known metal frame (commonly known as a metal panel) instead of glass. Therefore, this first reticle member adjustment screw 12
With this operation, the first reticle member holding cylinder 8 is deflected in the directions of arrows A and B with the support member 10 as a fulcrum. As shown in FIG. 2, 13 and 14 are horizontal scales for distance measurement and vertical scales for distance measurement arranged on the upper half of the first reticle member 4 and intersect in a cross shape. The horizontal distance measuring scale 13 and the vertical distance measuring 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 an animal, can be known. The horizontal distance scale 13 and the vertical distance scale 14 are graduated according to the following relationship. In general, animals 15 as shown in FIGS.
If you know the average torso length L or average torso thickness T, you can find the distance. Specifically, each scale of the horizontal distance scale 13 and the vertical distance scale 14 corresponds to a distance of 100 yards (91 m).
The scale corresponds to the size of 1 inch (2.54 cm). Therefore, the animal 1 reflected on the first reticle member 4
The distance can be determined by how many scale marks the length L or thickness T of the body appears in No. 5. Table 1 shows the average trunk thickness T of the target animal.
The relationship between the distance and the size (length or thickness) of the animal 15 is shown.

[Table] For example, if you visually read that the body thickness T of the large deer animal 15 currently reflected on the first reticle member 4 is 12 scales on the distance vertical scale 14, the distance is 200 yards (approximately 182 m). I understand. This table is useful for hunters to carry with them at all times. P is the cross center part. (b) Regarding ballistic drop correction. Reference numeral 16 denotes a ballistic drop correction scale placed on the lower half of the first reticle member 4 and positioned at the focal point of the objective lens 2. This ballistic drop correction scale 16 has one scale.
Compatible with 100 yards (91m) and 1 MOA
(minute of angle) (ballistic drop angle (minutes)). Gun owners generally know the MOA of ballistic drop depending on the distance of their gun. For example, Table 2 shows.

[Table] The MOA value differs depending on the type of gun and the type of bullet. The second reticle member 6 described above has a retaining ring 17.

Reference numeral 30 denotes an index plate constituting a lens on which an index 31 is placed, and is fitted into the window 32 of the index plate holder 28. Reference numeral 33 denotes a cap rotation stopper provided at the lower end of the cap 23, which corresponds to the stopper 34 of the index plate holder 28 described above, and is configured to prevent the cap 23 from rotating more than one rotation. 35A to 35H are distance rings loosely fitted into the annular shallow grooves 37 machined on the outside of the cylindrical portion 36 of the cap 23, and are for distances of 100 yards and 200 yards.
They are for yards, 300 yards, 400 yards, 500 yards, 600 yards, 700 yards, and 800 yards. Distance display numbers 100, 200, 300...800 and an index 57 are arranged on each distance ring 35A to 35H. 38 is a rotational positioning screw attached to each distance ring 35A to 35H, and 39 is a distance ring fixing screw attached to each distance ring 35A to 35H. Thus, each distance ring 35A to 35H is attached to the cylindrical portion 3.

Reference numeral 47 is a screw that passes through the inner cylinder 41, and has the function of allowing the connecting shaft member 40 to rotate only horizontally without vertically moving it by protruding and loosely fitting the tip of the screw into the annular recess 48 of the connecting shaft member 40. are doing. This inner cylinder 41 is screwed and fixed to the telescope barrel 1 via a threaded portion 49. Reference numeral 50 denotes a rotation stopper screw that passes through the inner cylinder 41 and has its tip projected into the arc-shaped slot 52 of the actuator 51. A thread 55 is threaded into a part of the actuator 51, and is threaded into a thread 56 provided inside the cylindrical portion 53 of the connecting shaft member 40, and the lower end 54 is threaded into the erector tube 5. It is brought into contact with the end portion 22. When the cap fixing screw 24 is tightened, the cap fixing screw 24, the cap 23, and the connecting shaft member 40 become integrated, and then the cap 23

will be moved through. (Effects) (a) Regarding trajectory correction effects. The telescope tube 1 is attached to a gun (not shown), and then the gun is firmly fixed to a base (not shown). Then test fire one shot at the 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 12
A is operated appropriately to place the cross center portion P of the first reticle member 4 at the impact point R of the test shot described above.
Match. (See Figure 10) That is, the first reticle member adjustment screws 12 and 1
By the operation 2A, the first reticle member holding cylinder 8 is deflected about the support member 10 as a support axis. Now that the first reticle member 4 has been set, it is fixed with a first reticle member fixing set screw (not shown) so that the set position does not shift due to impact. Next, loosen the cap fixing screw 24 in one trajectory correction device 7, remove the cap 23, and connect the screwdriver etc. to the groove 40 of the shaft member 40.
A and rotate the connecting shaft member 40. The other trajectory correction device 7A, which is disposed at an angle of deviation of 90 degrees, is operated in the same manner as described above. Thus, the cross center portion Q of the second reticle member 6 is made to match the cross center portion P of the first reticle member 4. Specifically, the thin aiming line 18 as shown in FIG.
When the connecting shaft member 40 is appropriately rotated through the groove 42A to align the cross center portion Q of the first reticle member 4 with the cross center portion P of the first reticle member 4 as shown in FIG. It is regulated and moves in the vertical direction via the threads 55 and threads 56. Therefore, the lower end 54 of the actuator 51 presses the other end 22 of the erector tube 5, deflecting the erector tube 5 in the direction of arrow C or D using the support member 20 as a fulcrum, and the telescope tube 1 The cross center portion Q of the thin aiming line 18 in the immovable second reticle member 6 fixed to can be optically aligned with the cross center portion P. Next, the cap 23 is fitted and rotated appropriately until the cap rotation stopper 33 abuts against the stopper 34 of the indicator plate holder 28 in the right direction. Thereafter, by tightening the cap fixing screw 24, the cap fixing screw 24, the cap 23, and the connecting shaft member 40 are integrated. Therefore, the impact point R of the test shot at a distance of 100 yards
The cross center portion P of the first reticle member 4
and the cross center portion Q of the thin aiming line 18 of the second reticle member 6, so the distance is
Loosen the distance ring fixing screw 39 of the distance ring 35A for 100 yards, rotate the distance ring 35A appropriately, and set the index 57 to the index 3 of the index plate 30.
Set to 1. Next, the distance ring fixing screw 39 is tightened to fix it to the cap 23 of the distance ring 35A. This completes trajectory correction for a distance of 100 yards. Next, correct the trajectory for a distance of 200 yards by referring to Table 2 without actually firing. Specifically, the cap 23 of the trajectory correction device 7
When rotated to the left, the horizontal thin aiming line 18A of the second reticle member 6 is directed to the cross center of the first reticle member 4 via the linking shaft member 40, actuator 51, and erector tube 5, as shown in FIG. It moves vertically downward with respect to portion P, that is, in the direction of arrow E. Therefore, from Table 2, the MOA value for a trajectory drop at a distance of 200 yards is "1", so the trajectory drop correction scale 16 on the first reticle member 4
The horizontal thin aiming line 18A of the second reticle member 6 is moved in the direction of the arrow E by one scale. Next, distance ring 35 for distance 200 yards.
Loosen the distance ring fixing screw 39 B and rotate the distance ring 35B 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 35B to the cap 23. This completes trajectory correction for a distance of 200 yards. If you wish to further correct the trajectory for distances from 300 yards to 800 yards, follow the same procedure as above for corrections for distances of 200 yards, referring to Table 2, and correct each distance ring 35C to 35H one by one. All you have to do is operate in sequence. (b) Regarding actual usage (example). It is assumed that trajectory correction has already been completed. Now, the deer animal 15 is the first reticle member 14.
If you visually read that the body thickness T is 12 inches (approximately 30 cm) on the distance vertical scale 14, the distance is
From Table 1, it can be seen that the distance is 200 yards (approximately 182 m). Therefore, the cap 23 is then rotated in a predetermined direction and the cap 23 becomes integral with the cap 23.
Align the indicator 57 of the distance display number "200" placed on the yard distance ring 35B with the indicator 31 of the indicator board 30. At that time, the cross center part Q is at the position Q ₂₀₀ (first
Figure 4). If the center of the animal 15 is set at this position Q ₂₀₀ and a shot is fired, the bullet will hit the animal 15 at a distance of 200 yards. (Effects) The present invention has the following unique effects. (a) Since the horizontal distance scale 13 and the vertical distance scale 14 of the distance measurement scale intersect in a cross shape, select either the length L of the body of the animal 15 or the thickness T of the body, whichever is easier to see. You can know the distance immediately after adopting it. (b) Cap 23 that constitutes the trajectory correction device 7
A plurality of distance rings 35A to 35H having a finger ring 57 on the outside of the cylindrical portion 36 is loosely fitted to rotate, and a connecting shaft member 40 having an actuator 51 is installed in the cap 23, and the actuator 51 is attached to the erector tube 5. Since they are in contact with each other, the distance ring corresponding to the distance known from the distance measuring scale can be immediately selected and the ring 57 can be brought into alignment with the index 31 of the index plate 30, thereby quickly correcting the trajectory. (c) Only one shot is required to correct ballistic drop.
