Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In the following description of the embodiments of the present invention, specific values are only examples.

Prior to the description of the present invention, the configuration of the prior art will be described with reference to FIG. 10 showing a front view showing the configuration of an embodiment of the scale according to the present invention.

The scale 100 according to the prior art embodiment includes a body 10 in the form of a thin plate extending from the scale bundle to which the lower part is coupled, a scale hole 11 formed in the body 10, And an auxiliary hole 13 formed at the center of the cross hat line pattern 12. The cross hat line pattern 12 is divided into four parts.

The scale 100 according to the prior art may be formed in the shape of a circular plate made of a synthetic resin or a metal such as aluminum or steel but may be formed in a polygonal shape if necessary. The thickness of the body 10 is 0.8 mm to 1.2 mm But it is not limited to this, and it can be made thicker or thinner depending on the convenience.

The crosshatch pattern 12 is formed so that the center thereof passes through the center of the scale hole 11 and divides the scale hole 11 into four portions having the same area as each other and overlaps the crest to replace the x and y axes of the suture So that it can be formed into a thin thickness t.

The auxiliary holes 13 are concentrically formed at the center of the cross-hair pattern 12 and are formed to have a diameter capable of forming a blurred circle at the top of the meshes of the clamp at the time of aiming, but are usually formed to have a diameter of 0.2 to 0.4 mm .

Fig. 11 shows an explanatory diagram showing a line of sight line in which a center line of the scale according to the prior art coincides with an upper end of an interlocking portion of the cutter, and Figs. 12A and 13B show the difference 13A and 13B show an open type and closed type latches of the prior art, and FIG. 13C shows an explanatory view showing a state in which a target is aimed at an open type latch on a scale using a scale according to the prior art Is shown

As shown in the drawing, the body 10 of the scale 100 according to the prior art has a diameter D1 of about 5 mm and the diameter D2 of the scale hole 11 is about 2 to 4 mm. However, as shown in FIGS. 12A and 12B, as the scale hole 11 becomes smaller as the distance from the scale hole 11 increases, the scale hole 11 becomes larger as the distance between the scale hole 11 and the scale hole 11 becomes smaller. D2 can be formed to be larger or smaller than 2 to 4 mm, if necessary.

When the shooter aligns with the shooting point of the target in a state in which the center of the body 10 or the auxiliary hole 13 and the upper end of the intermediate shaft 55a of the openable clamp 55 are aligned, Although the openable type lock 55 has been described here, the same can be similarly applied to the closed type lock 50. [

The intersection of the reticle pattern 12 of the scale 100 or the auxiliary hole 13 is positioned at the upper end of the meshes 51 and 55a of the latches 50 and 55 as shown in Fig. The center O of the scale 100 and the upper ends of the meshes 51 and 55a of the latches 50 and 55 come straight on and the alignment of the line of sight is facilitated.

Therefore, the shooter does not draw a virtual crosshair on the scale hole 11 and aim the intersection of the crosshair pattern 12 or the auxiliary hole 13 at the top of the intermediate shaft 51 of the catch 50 as shown in FIG. Since the alignment of the line of sight is easy, there is no need to concentrate the mind in order to draw a virtual crosshair, which can reduce the occurrence of fatigue due to mental concentration.

The shooter is aimed at the intersection of the cross pattern 12 of the scale 100 or the auxiliary hole 13 as shown in Fig. 13C so as to come to the top of the intermediate metal 51 of the openable latch 50, .

At this time, the focus of the eye of the shooter is directed toward the target, so that the scale 100 appears blurred as shown by the dotted line in FIG. 13c. When the intersection point of the auxiliary hole 13 or the cross line pattern 12 of the scale 100 which is seen to be blurred is matched to the target with the upper end of the open lever 50 aligned with the target, The center of the scale hole 11 and the upper end of the stopper 51 of the catch 50 coincide with each other and coincide with the target,

So that the shooter can not see the intersection of the ancillary hole 13 of the scale 100 or the crosshatch pattern 12 of the scale 100 which appears blurry without virtually drawing a crosshatch in the scale hole 11 of the scale 100, It is possible to align the line of sight by aligning it with the top of the iron (51) and aligning it with the shooting point of the target.

At this time, when the shooter pulls the trigger, the bullet accurately aligns with the shooting point of the target so that the shooter does not have to concentrate his mind to draw a virtual crosshair in the scale hole (11) of the scale (100) And can reduce fatigue due to mental concentration.

As to the prior art and other prior arts, the gun used in the prior art was wide in the size of the keyhole, small in aperture size, and low in accuracy of shot.

Fig. 14 is a diagram showing a state of being aimed by a conventional articulation. When viewed from the aperture of the head of a shooter, the articulator of Fig. 1 attempts to match only the target in the preceding figure with the psychological subconsciousness of the shooter. This can be seen by the shooter to match the goal to the top of the catch, but the actual line of sight may not. Therefore, the prior art is a technique for preventing the erroneous line-of-sight alignment due to the optical illusion of the shooter by narrowing the aperture and enlarging the aperture.

It is not easy for the shooter to overcome the optical illusion because the width of the aperture and the aperture of the catch is fixed. The width of the latch is about 2mm, which is to prevent the upper end of the latch from colliding with the surrounding objects and breaking or bending while carrying the gun. However, the gun collides with other objects in the vicinity and is destroyed. The scale, which is a protective metal plate next to the key, exists to prevent such an accident.

Therefore, by making the width of the upper part of the upper part as large as shown in Fig. 14, the target can be seen more clearly and the fatigue of the eyes of the shooter can be reduced. Also, after the improvement, it becomes easier to aim the clamp at the center of the aperture as the aperture becomes larger, and as the upper edge of the clamp becomes narrower, quicker adjustment becomes possible.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view showing the configuration of a circular scallop bundle 100 according to an embodiment of the present invention. 3, the circular wedge bundle 100 includes an upper wool 110 concentrically formed with the scale 7a and a fixing body 120 connected to the wool 110 to be fixed to the personalizer. The fixing body 120 includes a cleck adjusting device 130 provided on the upper surface of the fixing body 120 and a fixing member 124 provided on the upper rear surface of the fixing body 120. The cuticle wool bundle 100 according to the present embodiment is in the form of a disk made of synthetic resin, metal such as aluminum or steel, but may be formed in a polygonal form if necessary, and the thickness of the cuticle wool bundle 100 is also limited But can be made thicker or thinner depending on the convenience.

The wedge wool 110 is connected to the clique adjusting device 130 because height adjustment is essential for the shooter to be concentric with the scale 7a. It is preferable that the cleck adjusting device 130 is provided on the upper surface of the fixing body 120. The wick 110 has an wick thread screw 111 which is connected to the holding body 120 and the cluck adjusting device 130 so that the cluck adjusting device 130 The height of the wool 110 is adjusted. A detailed description thereof will be described later with reference to Figs. 5 to 6.

The fixing member 120 includes a fixing leg 121 connected to the hinge 122 and a fixing screw 123 for attaching and detaching the fixing member 121. The fixing leg 121 connected to the hinge 122 is rotated at a predetermined angle It is possible to go to the jar of the personal fire by going out. At this time, it is preferable that the latch 4a is located on the rear row total row, and as an example of this, FIGS. 4 and 8 to 9 can be referred to. Fig. 4 shows an embodiment in which the fixing screw 123 and the fixing leg 121 are combined, and Figs. 8 to 9 show an embodiment of the wick assembly 100 coupled on the total heat. 8 to 9, the knocker bundle 100 is located on the rear surface of the knob 4a, and may be spaced apart from the rear surface of the knob 4a by the fixing member 124 at this time. The fixing member 124 serves as a guide for mounting the clevis bundle 100 in a spaced apart position where the clevis 4a appears to be of a suitable size when the shooter aligns with the line of sight.

8 to 9, when the scallop bundle 100 is coupled to the barrel, the scissors must acquire a zero point concentric with the scallop 110 and the scale 7a. If a conventional zero point gun is used, it is possible to acquire a zero point with a minimum concentricity shot. Even if the zero point is not adjusted, it is fired by a line of sight using a concentric circle. Therefore, Can be obtained. Since the zero point is different for each gun before the wedge bundle 100 is utilized, it is also necessary to adjust the wedge cloak. Hereinafter, an embodiment of adjusting the clearing of the wedge 110 using the cleke adjusting device 130 will be described.

Figures 5 and 6 illustrate an embodiment of cleat adjustment of the wedge, wherein the cleat adjustment device 130 may be configured in the same manner as the time adjustment of the clock. The cleke adjusting device 130 includes a crown 131, a height adjusting screw 134, a gear 133 for changing the rotational direction, and a shaft 132 connecting the crown 131 and the height adjusting screw 134. When the crown 131 is pulled, the shape becomes as shown in FIG. 6 (a), and the height adjustment screw 134 pulled together with the shaft 132 is engaged with the wedge screw 111. At this time, when the crown 131 is rotated, the height adjusting screw 134 is loosened so that the wedge 110 can be raised or lowered. Referring to FIG. 6 (b), the adjustable screw 111 and the height adjusting screw 134 are engaged with each other to adjust the height. The rotation shaft is changed to a right angle by the gear 133, so that the height adjusting screw 134 rotates about the vertical axis, and the height adjustment can be made by rotating the wedge screw 111. When the crown is rotated, it is rotated in the parallel axis direction, and the rotation direction is switched in the vertical axis direction by the gear 133. The gear 133 is made up of a pair and can block the movement except the rotation by a member for fixing each other. And moves in the same manner as the pushing and pulling motion of the crown 131 in connection with the clamping leg 136 described later. When the height adjustment is completed, the height adjustment of the wedge 110 can be completed by pushing the crown 131.

When the height of the claw 110 is adjusted by pushing the crown 131 as shown in FIG. 5 (a), the height of the claw 110 may be changed by vibration or shock when the firearm is used. Thus, a device for securing it is needed, which allows the scissors screws 111 to be secured through the fasteners 137. When the crown 131 is pushed, the fixing pin 136 connected to the gear 133, the supporting shaft 135 supporting the fixing leg 136, and the fixing pin 137 connected to the other end of the fixing leg 136, So that the scalloped screw 111 can be fixed. Referring to FIG. 5 (b), the scalloped screw 111 and the height adjusting screw 134 are spaced apart from each other and the scalloped screw 111 is engaged with the scalloped screw 111 to fix the height. At this time, the angle of the fixing leg 136 connected to the fixing pin 137 is fixed, and the angle between the gear 133 and the fixing leg 136 can be opened so that the fixing pin 137 is engaged To be fixed to the wool screw (111). When the height of the claw 110 is adjusted by pulling the crown 131, as shown in FIG. 6, the height adjusting screw 134 is moved toward the claw screw 111, so that the claw 137 Is attached to the scalloped screw 111 to be released.

The height of the wedge 110 can be adjusted through the crown 131 and the height of the wedge 110 can be adjusted by rotating the wedge 110 directly and by tightening and loosening the wedge screw 111. [ An embodiment of this will be described with reference to Figs. 7 to 9. Fig. The present invention can adjust the height by rotating the crown as in the above-described method, but in another embodiment, the height of the claw screw 111 can be adjusted by rotating the claw wool 110.

7 (a) is a side view, and FIG. 7 (b) shows a state in which the shaft 132 connected to the crown 131 is coupled to the scraper screw 111, and FIG. 7 Front view. The shaft 132 may be configured as shown in FIG. 8 to fix the screw 111 to the scalloped screw 111.

The shaft 132 is engaged with the groove 112 by drawing the groove 112 in the front and rear faces of the wick thread screw 111, that is, in the direction in which the wedge wool is viewed and in the opposite direction as shown in FIG. 8 (a) The screw 111 can be fixed. In this embodiment, the shaft 132 can be formed in a screw shape, and the depth at which the shaft 132 enters can be adjusted by rotating the crown 131. 8 (b) is a side view showing that the side surface of the scalloped wool screw 111 is threaded, and the height of the scalloped wool 110 can be adjusted by rotating it.

9 (a) and 9 (b) are plan views of the shaft 132 and the wick shaft screw 111 viewed from above. The crown 131 is rotated to push the shaft 132 and the shaft 132 is engaged with the groove 112 of the wedge screw 111 to fix the wedge screw 111. [ Thus, another embodiment of the height adjustment of the wedge of the present invention is described, and the scope of the present invention includes not only the above-described method but also similar embodiments.

As described above, the line-of-sight alignment using the circular wedge bundle 100 concentrically arranges the scale 7a and the wedge 110 and aligns the line of sight by utilizing the existing latches, thereby significantly shortening the time required for line- And it is possible to reduce the occurrence of fatigue caused by line alignment. The shooter is able to align the scale 7a and the wedge 110 concentrically as shown in Fig. 7 and to center the clevis 4a virtually in the crosshatch line, thereby enabling fast and easy line alignment. When the shooter aligns the line of sight, the focus of the shooter is aimed at the target, so the scale 7a appears blurred. At this time, positioning the latch 4a in the right center of the scale 7a requires considerable concentration, and the eye and mental fatigue also accumulate considerably. However, by introducing the scallop 110 located on the rear side of the scale 7a, even if the scale 7a appears blurred, it is possible to quickly concentrate the scallop 110 with the scallop 110. Since the scallop 110 is clearly visible Placing the scale 7a in the center can also be quickly and easily aligned.

As described above, the present invention has been described with reference to particular embodiments, such as specific constituent elements, and limited embodiments and drawings. However, it should be understood that the present invention is not limited to the above- And various modifications and changes may be made thereto by those skilled in the art to which the present invention pertains.
