Abstract

The invention of weapons for throwing projectiles without the use of combat charges, namely airguns for throwing harpoons. The purpose of the invention is to increase the performance of the shotgun by reducing the force required to act on the trigger during firing. A pneumatic gun for spearfishing includes a receiver 1, a barrel 2, a piston 3 and a trigger. The latter is made in the form of a trigger 5 with a magnet 13 on its upper shoulder 7 and whispered 9 with a magnet 14 on the long arm 10 and a hook 12 on the rear shoulder 11, interacting with a battle stop 4 of the piston 3. To fire a shot, press the lower shoulder 8 of the trigger hook 5. It rotates and magnet 13 approaches magnet 14 on sheptal 9. Due to the fact that magnets 13 and 14 with the same poles are directed towards each other, the magnetic force of mutual repulsion between them, increasing as the magnet 13 approaches the magnet 14, d It reaches such a magnitude that the hook 12 of the sear 9 comes out of engagement with the combat stop 4 of the piston 3. The released piston 3 of the pressure of the gas in the receiver moves forward and pushes the harpoon 19, a shot occurs. 3 il.

Description

The invention relates to the field of weapons for throwing projectiles without the use of combat charges, namely the pneumatic weapon for throwing harpoons.

The purpose of the invention is to increase the performance of the shotgun by reducing the force required to act on the trigger during firing.

FIG. 1 shows a pneumatic gun for spearfishing, longitudinal section; figure 2 - section aa in figure 1; I fig.Z - muzzle gun. I Air gun for underwater bkhota contains receiver 1, placed

The new gate 23, interacting with the groove 24 on the harpoon 19.

Air rifle for underwater hunting works as follows.

g To charge the gun, the harpoon 19 is inserted into the barrel 2 and the piston 3 is moved with it before placing its combat stop 4 on the hook 12 of the short arm 11 whispered 9 and the groove 24 of the harpoon 19 on the ball gate 23 of the lock 22.

10 To fire a shot, press the lower shoulder 8 of the trigger 5. It turns, overcoming the resistance of the spring 6, and the upper shoulder 7 approaches the receiver 1 and, consequently.

hem 9 from engagement with a combat stop 4 of the piston 3. The released piston 3 under the action of the pressure force of gas compressed in the receiver 1 moves along the barrel 2 forward 2g red, pushes the harpoon 19. A shot is fired.

The hook 12 is full to engage the piston support 4 of the piston 3, and the pusher whispered 9 interacting with the upper iOM 7 of the trigger 5 and the long disc 10 of the whisper 9.

In the trigger mechanism, the shep-Tala push rod is made in the form of two magnets 13 and 14, one (magnet 13) of which is mounted on the upper arm 7 of the trigger hook 5, and the second (magnet 14) on the long shoulder 10 whispered 9, while the magnets 13 and 14 of the same poles face one towards the other.

Receiver 1 and barrel 2 are made of non-magnetic materials.
