The present disclosure relates to a dot sighting device for use in a small arm such as a handgun, a pistol, or a rifle, and more particularly, to a dot sight device for use in a small arm with a fixing mechanism conveniently attachable to or detachable from a small arm.
In recent years, dot sight devices have been employed in small arms. Using the dot sight device, since a user can aim at a target by simply causing a dot reticle image reflected from a reflective mirror to be aligned with the target, a time required to aim at the target is reduced, and it is possible to cope with an urgent situation rapidly.
A housing 30 is arranged on the fixing plate 11 and screw-coupled with the fixing plate 11 engaged with the fixing groove 21 through a screw 7. As the screw 7 is fastened downwards, the fixing protrusion 12 is pushed upwards, so that the dot sight device is firmly fixed to the small arm.

Further, it is possible to provide a compact dot sight device for use in a small arm with a compact fixing mechanism in which a fixing screw is laterally inserted into a fixing groove.
Furthermore, it is possible to provide a dot sight device for use in a small arm which is compatible with various types of small arms having different sizes of fixing grooves.
Hereinafter, exemplary embodiment of the present disclosure will be described in detail with reference to the appended drawings.
First, a dot sight device for use in a small arm with a fixing mechanism according to a first embodiment of the present invention will be described in detail with reference to the appended drawings.
Next, a process of fixing the dot sight device to the small arm through the fixing mechanism according to the first embodiment of the present disclosure will be described with reference to
As illustrated in
The two adjusting members 140 are inserted into the insertion hole 131 of the fixing member 130 while screw-coupling with the coupling holes 123, and thus the fixing member 130 is assembled with the lower plate 120 of the dot sight device through the fixing protrusion 121.
In a state in which the adjusting member 140 does not provide expansion force to the fixing member 130, the fixing member 130 is coupled with the fixing groove 111 of the small arm slide 110 of the small arm in the dovetail manner. Then, as illustrated in
More specifically, when the adjusting members 140 are rotated and fastened in the state in which the leading ends 141 of the adjusting members 140 are laterally inserted into the insertion hole 131 of the fixing member 130, the leading ends 141 of the adjusting members 140 move forward in the insertion hole 131 while coming into point contact or line contact with the inner surface of the insertion hole 131, and thus the fixing member 130 expands centering on the slot 132 to push the inner walls of the fixing groove 111 and comes into close contact with the fixing groove 111. Accordingly, the dot sight device may be firmly fixed to the small arm.
Here, as illustrated in
When both ends of the insertion hole 131 have the diameter that gradually decreases toward the inside thereof corresponding to the leading end 141 of the adjusting member 140, the leading end 141 of the adjusting member 140 comes into surface contact with the insertion hole 131 of the fixing member 130, the leading end 141 uniformly pushes the inner surface of the insertion hole 131 by the leading end 141, and thus expansion force of the fixing member 130 is uniformly applied to the inner wall of the fixing groove 111.
At this time, since the fixing member 130 has a shape corresponding to the fixing groove 111 as illustrated in
In other words, since the fixing member 130 pushes the inner walls and the bottom surface of the fixing groove 111 while coming into close contact with the fixing groove 111 as indicated by arrows in
In addition, since the fixing member 130 is coupled with the fixing protrusion 121 through the adjusting member 140, force of the fixing member 130 pushing the bottom surface of the fixing groove 111 is transferred to the lower plate 120, that is, the dot sight device, and thus fixing force between the lower plate 120 of the dot sight device 120 and the small arm slide 110 increases.
Meanwhile, the dot sight device can be conveniently detached from the small arm by simply rotating and loosening the adjusting member 140. Specifically, as the adjusting member 140 is rotated and loosened, the leading end 141 of the adjusting member 140 moves back from the insertion hole 131, the fixing member 130 contracts, and thus the outer walls of the fixing member 130 come apart from the inner walls of the fixing groove 111. Then, since no fixing force is applied between the fixing member 130 and the fixing groove 111, the user can easily take the dot sight device from the fixing groove 111 of the small arm while pulling or pushing the dot sight device in the longitudinal direction of the fixing groove 111.
In addition, since the fixing member 130 can be selected from the plurality of fixing members 130 having the different sizes, the fixing mechanism according to the present disclosure is compatible with various forms of small arms.
Next, a dot sight device for use in a small arm with a fixing mechanism according to a second embodiment of the present disclosure will be described.
The difference with the dot sight device for use in a small arm with a fixing mechanism according to the second embodiment of the present disclosure lies in that a fixing member 130′ is rotated as the adjusting member 140 is fastened and selectively comes into contact with both inner walls of the fixing groove 111, and an aperture 136 formed in the fixing protrusion 121. Description of structure that is common with the first embodiment is omitted for brevity.
The fixing member 130′ includes a shaft 135 which is vertically coupled with the accommodation groove 122 and a pivot plate 134 which is placed on the accommodation groove 122 to pivot on the shaft 135. The shaft 135 may be provided by a screw secured to a screw formed in the fixing member 130′ near a center of the aperture 136. The pivot plate 134 is coupled to the lower plate 120 of the dot sight device as the shaft 135 is screw-coupled with the lower plate 120. Further, the fixing protrusion 121 includes the aperture 136 defined therein. When the pivot plate 134 is pushed and rotated by the adjusting member 141, the aperture 136 serves to allow the fixing member 130′ to come into contact with the fixing groove 111. The pivot plate 134 may be smaller than an opening of the aperture 136 to allow insertion into the aperture 136 and also larger than a width the fixing groove 111. Thus, when the pivot plate 134 is rotated about the shaft 135, the pivot plate comes into contact with the fixing groove 111 providing an interference fit. The pivot plate 134 has a trapezoidal shape, and the accommodation groove 122 has a conical shape corresponding to the trapezoidal shape of the pivot plate 134. But, the present disclosure is not limited to this example, and for example, the pivot plate 134 may have a rectangular shape, and the accommodation groove 122 may have a cylindrical shape corresponding to the rectangular shape of the pivot plate 134.
Specifically, as illustrated in

As another example, the fixing device may be used with other small arm accessories such as lights, optical sights, and laser sights.
