Description

PISTOL

TECHNICAL FIELD

The invention relates to a pistol that shoots with two types of cartridges without the need for replacement of parts. It is used as a means of self-defense and as a handgun.

BACKGROUND OF THE INVENTION

Heckler & Koch pistol known as NK4 is known, which consists of a barrel fixed to the frame by means of a lock allowing the barrel to be exchanged when firing with another caliber cartridge, a return spring mounted on the barrel and pressing the front end of the shutter, a filler. located at the bottom of the frame enclosing the frame. For firing with different types of cartridges (different calibers), the barrel is replaced with the return spring, shutter and filler. (1)

TECHNICAL NATURE

The task is to create a pistol that can shoot with two different caliber cartridges without replacing details.

The task was solved by creating a pistol consisting of a barrel fixed to the frame, a shutter put on the barrel, a return spring mounted on the barrel and pressing the front end of the shutter, a trigger-coupled trigger pull, and mounted at the rear end of the frame located at the bottom of the frame, which is retained by a lock box covering the frame with the profile of the groove of the barrel is polygonal with a ratio of the dimensions in the fields and notches allowing sectional 62,5 mm ² along which the Kurshun and cartridges of two different calibers (from 9x19 mm and 9x18 mm). The barrel cartridge is filled with a cone larger than the cone of the sleeve 9x18 mm, but smaller than the cone of the sleeve 9x19 mm so as to base equally the sleeve of the cartridge 9x19 mm and the cartridge 9x18 mm. The inertial exit of the striker in front of the "mirror" of the shutter is selected in size and requirements for a 9x18 mm cartridge so that the capsules of both cartridges are equally well broken. Below the barrel is a chamber in which a piston enters, the front end of which is pivotally connected to the shutter and the chamber is connected to the barrel by a gas outlet.

In the second embodiment of the invention, the pistol consists of a barrel fixedly mounted in the frame, a shutter put on the barrel, a return spring mounted on the barrel, and pressing against the front end of the barrel, a trigger actuated by a thrust trigger and mounted in the rear.

.......... ... J edge of the frame, filler located at the bottom of the frame, which is held by a lock, a bed enclosing the frame, the barrel groove profile being polygonal with the aspect ratio and sections of 62.5 mm ² , through which bullets of two different caliber cartridges (9x19 mm and 9x18 mm) pass. The barrel cartridge is filled with a cone larger than the cone of the sleeve 9x18 mm, but smaller than the cone of the sleeve 9x19 mm so as to base equally the sleeve of the cartridge 9x19 mm and the cartridge 9x18 mm. The inertial exit of the striker in front of the "mirror" of the shutter is selected in size and requirements for a 9x18 mm cartridge so that the capsules of both cartridges are equally well broken. The shutter consists of a housing with a rear insert and a shutter head connected to a retarder. The shutter release is slowed down by the movement of split tables (shutter head and back cover) of the shutter connected to a retarder.

The advantages of the invented gun according to the invention are as follows.

The pistol is equipped with a fixed barrel with a polygonal profile, which provides high wear resistance and very good accuracy and grouping of shooting.

The pistol can shoot with 9x18 mm (Makarov) cartridges, of which there are large stocks.

The gun can shoot with the most popular cartridges 9x19 mm (Para). The gun can shoot with ammunition ammunition (Police) cal 9x18 mm (Makarov). The gun can fire ammunition of the listed types loaded together in the cartridge.

Additional benefits for the second option:

Slowly decreasing shutter speed, which is conducive to target shooting.

Minimum forces and moments perpendicular to the axis of the barrel that affect the dispersion of the firing.

EXAMPLES FOR IMPLEMENTATION

Option one

The pistol (FIG. 1) consists of a barrel 1 fixedly fixed in the barrel block 13 by means of a pin 14, the chamber 4 which is connected to the barrel 1 by the opening 16 in the bottom of the barrel block 13. (together with barrel 1 and chamber 4) is attached to the frame 3 by guide channels and fixed fixedly with the locking axis 15. A return spring 2 is fitted to barrel 1. A trigger mechanism 9 is mounted at the rear end of frame 3. A trigger 7 is mounted in the middle of frame 3, which is coupled to a trigger mechanism 9 by means of a thrust 8. Frame 3 is mounted in the housing 12, with an opening for inserting the filler 10 in the lower end of the bed and the frame, which is retained by a lock of the filler 11. The closure 6 is pivotally connected to a piston 5. The closure 6 is located above the frame 3, like the front its opening is fitted to barrel 1 and its rear end is guided to the frame, and at the same time in that the piston 5 is in the chamber 4. In the shutter 6 is installed a striker 17.

Option two

The pistol (Fig. 2 and Fig. 3) consists of a barrel 1 fixedly fixed in the frame 3. A return spring 2 is fitted to the barrel 1. A trigger mechanism 9 is mounted at the rear end of frame 3. In the middle of frame 3 a trigger 7 is mounted, which is coupled to the trigger mechanism 9 by means of a thrust 8. The frame 3 is mounted in the box 12, with an opening for inserting the filler 10 at the lower end of the box and the frame being held by the filler lock 11. The shutter 6 consists of a housing 18 in which a shutter head 19, a retarder 20 and a rear insert 21 are mounted. vorat 6 is located above the frame 3 by its front hole is sleeved on the barrel 1, and its rear end is in the rails of the frame. An insert 17 is mounted in the insert 21, which is pressed back by a spring 23, and a cable 22 is mounted in the head of the jail 19.

WAY OF ACTING

Option one

On firing, after the bullet begins to move in the barrel, part of the gunpowder gases pass from the barrel 1 through the opening 16 to the chamber 4 and act on the piston head 5, thereby delaying the recoil of the barrel 6 and removing the cartridge sleeve from the barrel chamber. (location D) occurs at a time when the pressure of the Gaseous Gases begins to drop. The combination of the mass of the shutter 6 the force of the return spring 2 and the dimensions of the chamber 4 and the piston 5 is so selected that the gun can fire the cartridges described above without having to replace the details.

Option two

In standby, before firing, shutter 6 is in the extreme forward position. When fired, the propellant gases through the bottom of the sleeve apply a force that is received from the head of the shutter 19. The head of the shutter 19 begins to move in place (C) the retarder 20, which is pivotally connected to the insert rear 21. To allow the shutter 6 to make a backward movement, the retarder 20 rotates about its axis (C), exits the copier profile area of the frame 3 (location B) and allows the shutter 6 to move backwards. As a result, the rear 21 insert and housing 18 are removed from the head of the shutter 19. The recoil energy absorbed by the rear 21 insert and housing 18 makes it a leading unit, which, due to its greater mass, reduces the shutter speed of the shutter 6. The greater curvature of the head of the jail 19 at the beginning of the recoil is provided by the gear ratio of the retarder 20.
