Description

CROSS-REFERENCE TO RELATED APPLICATION

rightward leftward, the stopper 130 is separated from the ring-shaped insertion groove 128 placed at a right side of the trajectory correcting unit 120 of FIG. 6, and then the rotary shaft 121 of the trajectory correcting unit 120 is moved rightward leftward as shown in FIG. 10 so that the second polygonal cam 122b formed on the rotary shaft 121 can be placed at a position corresponding to the contact unit 112a of the base 112. Further, the stopper 130 is coupled again to the ring-shaped insertion groove 128 placed at a left side of the trajectory correcting unit 120 exposed to the outside of the gun barrel supporter 111, and thus the position of the trajectory correcting unit 120 is set.

In the state that the position of the trajectory correcting unit 120 is set as described above, if the rotary shaft 121 is rotated while gripping the grip 124, the angle between the gun barrel supporter 111 and the base 112 is adjusted by the second polygonal cam 122b to thereby correct the trajectory of the bullet having the trajectory A.

Although the same level reference surfaces of the first polygonal cam 122a and the second polygonal cam 122b are illustrated as seen on the front, the same level reference surfaces of the first polygonal cam 122a and the second polygonal cam 122b are in contact with the contact unit 112a while movement is performed between the first polygonal cam 122a and the second polygonal cam 122b as described above.

FIG. 11 is a cross-section view showing that a rotary shaft 121, 121′ is replaced in an apparatus for multi-correcting a trajectory according to an exemplary embodiment of the present invention.

As shown in FIG. 11, in the trajectory correcting unit 120 according to an exemplary embodiment of the present invention, since the rotary shaft 121 and the grip 124 are detachably assembled, it is possible to separate the rotary shaft 121 from the through hole 111a of the gun barrel supporter 111 in the state that the grip 124 is separated from the rotary shaft 121.

That is, in the state that the rotary shaft 121 is inserted in the through hole 111a of the gun barrel supporter 111, the grip 124 is detachably coupled to one end part of the rotary shaft 121. The grip 124 is separated from the rotary shaft 121, and then the rotary shaft 121 is pushed rightward in FIG. 11 and separated from the gun barrel supporter 111. Then, other rotary shafts 121′ respectively formed with polygonal cams 122′ for correcting the trajectory with regard to a bullet having a trajectory C or a bullet having a trajectory D different from the trajectory A or the trajectory B are inserted into the through hole 111a of the gun barrel supporter 111, and then the grip 124 is assembled, thereby being applicable to a firearm for a bullet having a different caliber.

Accordingly, in the apparatus for multi-correcting a trajectory according to an exemplary embodiment of the present invention, the rotary shaft formed with the polygonal cam 122 for correcting the trajectory corresponding to the caliber of the bullet of the firearm in which the dot sight or the optical sight is installed can be coupled and used to the gun barrel supporter 111, or the rotary shaft 121 can be moved leftward or the rightward for correcting the trajectory corresponding to the caliber, thereby enhancing equipment use efficiency.

Meanwhile, as shown in FIG. 11, the grip 124 detachably coupled to the rotary shaft 121 is assembled as a rod p penetrating the grip 124 is fastened to a fastening hole 121b formed at one end part of the rotary shaft 121 in the state that the grip 124 is assembled to surround one end part of the rotary shaft 121.

As apparent from the above description, there is provided an apparatus for multi-correcting a trajectory, in which one dot sight or optical sight can be mounted to firearms using bullets different in the trajectory or firearms different in a caliber from one another, thereby enhancing equipment use efficiency.

Also, there is provided an apparatus for multi-correcting a trajectory, in which a position of a rotary shaft can be prevented from being arbitrarily changed in the state that polygonal cams plurally formed in one rotary shaft are selected.

Further, there is provided an apparatus for multi-correcting a trajectory, in which the rotary shaft can be replaced to be easily applied and mounted to a firearm having an unprecedented new caliber.

While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
