Dot sight fixing device for pistols {FIXING DEVICE OF DOT-SIGHT FOR A HANDGUN}

The present invention relates to a dot sight fixing device for a pistol, and more particularly, to a dot site fixing device for a pistol that can be easily detached by arranging a screw for fixing the pistol slide to the fixing groove on the side of the fixing protrusion.

In general, in the case of a pistol, aiming by alignment of the aiming line consisting of scales, scales, and targets (targets) is aimed at, aiming the barrel at the target precisely, and aiming quickly so that the targets, scales, and scales are in a straight line. very important.

However, the pistol has a problem in that it is difficult to align the line of sight even with small vibration or tremor, and it is disadvantageous for the quick aiming required in near or imminent situations. In other words, this type of aim shooting method requires complicated process and time such as target acquisition and confirmation, sight line alignment, and aiming. Also, since the scale and the scale itself are very small, they are sensitive to small tremors. If you care too much about aligning your line of sight, your eyes will be focused on the scale and the scale itself, rather than the target or frontal situation.

An optical sight was proposed to improve the accuracy while resolving the hassle of alignment. However, because of the use of a telephoto lens in the case of an optical sphygmomanometer, when the magnification of the lens is raised, it is also sensitive to a small vibration.

To solve the above problems, it adopts a non-magnification (low magnification) lens and eliminates the complicated line of sight alignment consisting of scales, scales and targets (targets), and simply dots and targets (targets) within the effective diameter of the aimer. An optical dot sight collimator is proposed that aims if the bay is matched.

Conventional dot sight sighting device is characterized in that a simple and quick aiming is possible, such as US Patent No. 6,327,806 (hereinafter, referred to as reference document 1), and has a very useful advantage in an urgent situation or short distance requiring rapid response.

As described above, in the state where the fixing member 130 is assembled to the dot sight 120 and the pressing force by the adjusting member 140 is not provided, the fixing protrusion 121 and the fixing member 130 of the dot sight 120 are removed. Coupled to the fixing groove 111 of the pistol slide 110 in a dovetail (dovetail) method, and then the adjustment member 140 screwed to the fastening hole 123 of the fixing member 130 as shown in FIGS. Rotation in the tightening direction to add a fixing force so that the fixed position of the dot sight 120 is not arbitrarily changed by the trigger shock or external impact.

Looking at the process of adding a fixed force in detail as follows.

First, in the state in which the front end portion 141 of the fixing protrusion 121 is inserted into the insertion groove 131 of the fixing member 130, as shown in FIG. 8 when the adjusting member 140 is rotated in the tightening direction, the adjusting member 140 The front end portion 141 of the) is advanced in the insertion groove 131 of the fixing member 130, and thus the lower end of the fixing member 130 separated to both sides by the incision 132 fixing groove 111 Both sides of the side extend toward the inner wall surface.

At this time, although not shown in the drawings, when the inclined surface is formed on any one of the inner circumferential surface of the insertion groove 131 of the fixing member 130 and the outer circumferential surface of the front end portion 141 of the adjustment member 140, the front end portion of the adjustment member 140 It is possible for 141 to extend the fixing member 130 in both directions by providing a pressing force to the fixing member 130 while being in point or line contact with the insertion groove 131 of the fixing member 130.

In addition, when the inner circumferential surface of the insertion groove 131 of the fixing member 130 and the outer circumferential surface of the front end portion 141 of the adjusting member 140 are inclined surface contact with each other, the fixing member 130 of the fixing groove 111 Since the pressing force applied to the inner wall surface acts evenly in response to the surface contact area of the insertion groove 131 and the tip 141, the inner peripheral surface and the adjustment member 140 of the insertion groove 131 of the fixing member 130 mentioned above. Compared to the case where the inclined surface is formed on any one of the outer circumferential surface of the distal end portion 141 of the), the range in which the pressing force acts increases.

At this time, since the fixing member 130 is inserted into the fixing groove 111, as the lower end of the fixing member 130 opens in both directions as shown in FIG. 8, both side outer walls of the fixing member 130 have a primary action. Since the surface is in close contact with both inner wall surfaces of the fixing groove 111, and the cross section of the fixing member 130 and the fixing groove 111 is formed as an inclined surface as shown in the drawing, the outer wall surface of the fixing member 130 is fixed by the secondary action. The bottom surface of the fixing member 130 is in close contact with the bottom surface of the fixing groove 111 while sliding in the inner wall surface of the groove 111.

That is, according to the present invention, since the fixing member 130 inserted into the fixing groove 111 as shown in the arrow in Figure 8 is in close contact with the entire contact surface with the fixing groove 111, the contact friction force is increased compared to the conventional Will have the effect.

In addition, since the fixing member 130 is connected to the fixing protrusion 121 of the dot sight 120 through the adjusting member 140, the fixing member 130 moves toward the bottom surface of the fixing groove 111. The force to be transmitted to the dot site 120, and the bottom surface of the dot site 120 is in close contact with the upper surface of the pistol slide 110, thereby increasing the fixing force.

On the other hand, when the dot sight 120 is to be separated from the pistol, the pressing member 141 of the adjusting member 140 is released to the fixing member 130 by rotating the adjusting member 140 in the tightening direction. When the fixing member 130 contracts, the contact with the fixing groove 111 is released, so that the dot sight 120 can be separated by moving in the longitudinal direction within the fixing groove 111 of the pistol slide 110. Done.

In addition, since the fixing member 130 is fixed to the dot site 120 through the adjusting member 140 as shown in FIG. 5, the front end portion of the adjusting member 140 is rotated by rotating the adjusting member 140 in the tightening direction. When the 141 is separated from the insertion groove 131 of the fixing member 130, the fixing member 130 is separated from the receiving groove 122 of the dot site 120. That is, since the fixing member 130 can be exchanged from the dot sight 120, therefore, to provide the fixing member 130 that meets the fixing groove 111 of the target pistol to which the dot sight 120 is to be installed. This makes it easy to assemble to various types of pistols.

On the other hand, according to a modification of the fixing member 130 according to the dot sight fixing device for the pistol of the present invention as shown in Figure 9, perpendicular to the longitudinal direction of the fixing groove 111 on the outer surface of the fixing member 130 By forming grooves or protrusions 133 having a protrusion extending in the direction, the frictional force with the fixing groove 111 may be increased. That is, while the fixing member 130 extends toward the inner wall surface of the fixing groove 111 to be in close contact with the inner surface of the fixing groove 111, the uneven portion 133 may move toward the moving direction of the fixing member 130. Since it is formed in the direction orthogonal, the frictional force with respect to the positional movement of the fixing member 130 increases. Therefore, sufficient fixing force is provided even if the adjustment member 140 is not forcibly rotated in the tightening direction, so that the installation and detachment are simple, and the effect of preventing the installation position from being arbitrarily changed by the impact is provided.

Next, a dot sight fixing apparatus for a pistol according to a second embodiment of the present invention will be described.
