Abstract

Disclosed is a firearm having dual barrels comprising a firearm body which is equipped with a small caliber barrel and a large caliber barrel; a selector installed on one side of the firearm body to select the type of bullet and the mode of firing; a fire control system installed on the firearm body to enable aiming the target through detecting the target both at day and night time; a firearm switch unit installed on the firearm body to transmit the information on the firing of the bullet; a fuse setter installed on the firearm body to transmit the control signal of the fire control system to the fuse of the explosive bullet which is introduced into the large caliber barrel; and a sensor device unit installed on the firearm body to transmit the position of the selector and sensed firing signal to the fire control system.

Claims

1. A firearm having dual barrels comprising:

a firearm body 10 which is equipped with a small caliber barrel 11 which fires small caliber regular bullet, and a large caliber barrel 12 which fires explosive bullet, the regular bullet or explosive bullet being selectively fired through a trigger 13;

a selector 15 installed on one side of the firearm body 10 to select the type of bullet and the mode of firing;

a fire control system 20 installed on the firearm body 10 to enable aiming the target through detecting the target both at day and night time and to provide a firing data for explosive bullet by measuring the distance to the target;

a firearm switch unit 17 installed on the firearm body 10 to transmit the information on the firing of the bullet which is additionally input by the user to the fire control system 20;

a fuse setter 18 installed on the large caliber barrel 12 of the firearm body 10 to transmit the control signal of the fire control system 20 to the fuse of the explosive bullet which is introduced into the large caliber barrel 12;

and a sensor device unit 19 installed on the firearm body 10 to transmit the position of the selector 15 and sensed firing signal to the fire control system 20.

2. The firearm having dual barrels of the claim 1, wherein the selector 15 selects as the state value among an explosive bullet, single shot, burst shot and safe.

3. The firearm having dual barrels of the claim 1, wherein the fire control system 20 is equipped with a power switch 21 which is connected to the power supply 21 and introduces power to the daytime mode or night mode, a firearm connecting unit 25 for the interface with the firearm body 10, a laser range finding unit 22 for measuring the distance to the target, a thermal image sensor unit 23 for detecting thermal image in the night mode, an image display unit 26 which displays on the optical lens device 27 the target distance acquired by the laser range finding unit 22 and the thermal image detected by the thermal image sensor unit 23, a power distribution unit 28a which supplies power to each units, and a ballistic trajectory calculation unit 28b which calculates the bullet trajectory according to the target distance, and comprises a main control unit 28 which controls each device according to the signal of the firearm body 10 transmitted by the firearm connecting unit 25 and transmits the control signal of the fuse of the explosive bullet to the fuse setter 18, and a menu selecting switch 29 which enables selecting of the menus for controlling internal devices.

4. The firearm having dual barrels of the claim 3, wherein the fire control system 20 comprises a sensor unit 24 comprising an inclination sensor detecting the inclination of the firearm body 10 and a temperature sensor, and the main control unit 28 changes the reticle displayed at the optical lens device 27 according to the inclination of the firearm body 10 and the temperature information.

5. The firearm having dual barrels of the claims 1, 2, 3 and 4, wherein the firearm switch unit 17 comprises a laser emitting switch 17a installed on the fire control system 20 for controlling the laser range finding unit 21, a range increment switch 17b and range decrement switch 17c for controlling the range to the value determined according to the detected range, and a fuse mode selection switch 17d for determining the mode of explosion of the explosive bullet.

6. The firearm having dual barrels of the claims 1, 2, 3 and 4, wherein the fuse setter 18 transfers the energy required for the explosive operation of the fuse receiving unit of the explosive bullet in the way of non-contacting magnetic induction, and transmits the range information determined at the fire control system 20 to the fuse receiving unit 31.

7. The firearm having dual barrels of the claim 6, wherein the range information is input before the primer of the explosive bullet is fired by the firing pin in the large caliber barrel 12.

8. The firearm having dual barrels of the claims 1, 2, 3 and 4, wherein the sensor device unit 19 comprises a selector position measuring unit 19a for detecting the position of the selector 15 and a firing signal sensing unit 19b which generates a firing signal according to the movement of the trigger 13.
