Abstract

The "Kondor M96" self-loading pistol with open hammer with simple or doubled action has a free breech-mechanism with partial retardation. The partial retardation of the breech-mechanism at shooting is performed by means of dynamical interaction of the parts of the pistol- the frame, the barrel, case-breech mechanism of the barrel and the back spring. The case-breech mechanism of the barrel and the frame are made of light alloy. The breech mechanism and the barrel are made of steel, as removable parts. At replacement of the barrel, the insertion-breech mechanism and the magazine it is possible to use the shells with different caliber and length. In the pistol there is used original design of the back-blow shock absorber of the barrel case-breech mechanism. The pistol can be used in army, and in the HA units, as individual means for close combat for attack and defense, and as means for individual protection with application of shells with rubber bullets, gas, sound and shot charges.

Description

Description of the invention

The invention relates to the field of weapons. A self-loading pistol with an open trigger belongs to class 2 semi-automatic weapons. The type of automatic operation is a free shutter with partial braking. It has a store supply of cartridges. The gun can be used in the army, for units of the Ministry of Internal Affairs and security, as an individual means of close combat for attack and defense, as well as as a means of individual protection using cartridges containing rubber bullets, gas, noise and shot charges.

Analogues in the type of automatic operation are the Makarov pistol of the 1951 model, the "Fort-12", "Fort-14" 70 pistols | other pistols with a similar type of automatic operation.

The closest analogue is the prototype - a Browning pistol of the 1903 model, in which the type of automatic operation and the method of fastening the barrel are similar. The prototype has the following parts: a frame, a barrel, a barrel-bolt casing with a recoil spring, a recoil spring rod, a guide sleeve of the barrel that fixes the recoil spring, which closes the recoil spring and barrel-bolt casing, an insert, a striker with a spring, a sear with a spring, 79 trigger, a spring-loaded trigger that closes the magazine, a spring-loaded clip located in the lower part of the pistol grip, a spring-loaded automatic safety device located in the rear of the grip, a spring-loaded slide delay lever, a spring-loaded separator, a safety device that located on the left side at the top of the handle, magazine.

The prototype has the following disadvantages: the frame and casing-shutter of the barrel are made of solid steel - milled parts, which makes them heavier compared to the proposed design, in addition, their production requires high costs and is labor-intensive; the closed trigger, which is located in the internal cavity in the rear part of the casing-barrel of the barrel, creates an inconvenience in operation: the 29 gun is not protected from the impact of the casing-barrel during the shot, which in turn leads to a gradual /«F, loosening of the fixing clutch of the return spring of the casing - the shutter of the barrel during operation, as a result of which it is possible to jam the movement of the casing-shutter of the barrel relative to the frame due to the distortion of the parts.

The proposed design is an analogue of the pistols listed above only according to the automatic operation scheme. According to the shutter braking scheme during the operation of automatic analogues, there are no masses. - 30 The possibility of achieving a similar result is realized in other designs by technical complication. with

In the proposed design, braking during a shot occurs due to the dynamic interaction of the parts of the gun itself - the barrel, the frame, the casing-barrel shutter and the return spring of the casing-barrel shutter. --

The invention is based on the task of creating such a gun, which uses frictional braking of the shutter when firing, as a result of which the power of the shot increases.

To solve the problem, a self-loading pistol is proposed, which includes a frame, a barrel, a casing-shutter of the barrel with a return spring, a rod of a return spring, a guide clutch that fixes a return spring, which closes a return spring and a casing-shutter of the barrel, an insert, a trigger with a spring , a spring-loaded striker, a spring-loaded sear, a trigger, a trigger with a return spring, a spring-loaded clip that locks the magazine, which was located /«F the lower part of the pistol grip, a spring-loaded automatic safety device, which is located in the rear part of the Z 50 grip, bolt delay lever with a spring, a separator with a spring, a fuse located on the left side in the upper part of the handle, a magazine in which, according to the invention, the barrel, the frame, the cover-barrel of the barrel and the return spring of the cover-barrel of the barrel are made such that interact with each other, ensuring the creation of additional braking of the casing-shutter of the barrel when fired.

In the front part, the casing-barrel of the barrel contains longitudinal sliding grooves interacting with the sliding grooves 45 of the frame in the front part, the frame and the casing-barrel of the barrel are made of light alloy, and the bolt in the casing-barrel of the barrel is a removable part and is made of steel.

Ge») The barrel and the insert-shutter of the casing-shutter of the barrel are made removable, the clutch of fixing the return spring is closed in the front part of the casing-shutter of the barrel with a check, and the shock absorber of the shutter rollback is simultaneously a shutter-brake. o 20 Fig. 1 shows a general view of the design of the claimed device with details. In Fig. 2, the general view is the casing-shutter of the barrel in the extreme rear position. In Fig. 3, the front view is a bold line showing the profile of the front longitudinal grooves of the sliding frame and the casing-shutter of the barrel.

The gun includes: casing-bolt of the barrel - 1, frame - 2, barrel - C, insert-bolt, with an ejector fixed on it - 4, a clutch that fixes the return spring of the casing-bolt of the barrel - 5, a connecting check that fixes clutch of the return spring of the casing-barrel shutter - 6, the return spring with the stem of the casing-barrel shutter - 7, in. a trigger with a spring - 8, a trigger - 9, a sear with a spring - 10, a stop rod of a trigger with a mainspring - 11, a striker with a spring - 12, the rear protective bar-sight of the casing-barrel shutter - 13, which fixes the rod with a spring of the rear of the protective bar-sight - 14, which fixes the shutter-inset of the bracket with a spring -15, the insert-shock absorber of the casing-barrel shutter - 16, the button-locker of the magazine with a spring - 17, the trigger with 60 spring - 18, the magazine - 19, the case inserts of the shock-trigger mechanism with a reflector - 20, safety stop ring - 21.

The design of the claimed device solves several problems at the same time: weight reduction in relation to dimensions and power; increasing the power of weapons; because the level of survivability is high;

technological simplicity of weapons; high level of reliability in work; small recoil when firing, which allows for effective aimed fire; ease of operation and maintenance.

These problems are solved by using a light alloy barrel in the design for the manufacture of the frame and shutter casing; mutual arrangement and design of the parts of the gun, during the interaction of which there is a partial braking of the casing-shutter of the barrel during a shot. The high level of reliability in operation is due to the relatively simple design of the parts themselves and the possibility of their trouble-free operation in harsh modes of operation and significant wear and tear.

The technological simplicity of the design is achieved due to the design features of the gun parts, for the manufacture of which standard equipment can be used.

All parts operating under shock loads are made of steel 45, 50, 65M or similar with a hardness of not less than 45-50 units. (NCS).

The ability to effectively aim fire is due to several reasons: the relatively low location of the barrel; a small recoil when shot due to the use of a shock absorber of the casing-shutter of the barrel; the relatively low location of the stop point of the limiting clutch of the return spring of the casing-shutter of the barrel; the structural arrangement of the parts of the gun, in which the center of gravity of the main moving parts of the casing-shutter of the barrel is shifted as far forward as possible.

The design of the pistol does not contain threaded connections, except for 2 bolts for fastening the handle. Incomplete disassembly can be carried out without the use of a special tool.

The claimed device works as follows.

To bring the pistol to the combat platoon state, it is necessary: insert the magazine 19 with cartridges into the handle as far as it will go, while it is locked with the button - latch 17; pull the casing-shutter of the barrel (hereinafter "-shutter casing) 1 to the stop and release, while the cartridge is sent into the chamber, the trigger 9 is on the cocking, the trigger pull 18 with its upper protrusion is in the groove located in the lower part of the right outer wall casing-shutter 1 and thus the cutout located in the rear part (trigger rod) enters the M zo engagement with the sear 10.

To fire, you must press the trigger 8. The trigger pull 18, when moving back, deflects the sear 10, releasing the trigger 9. The trigger moves under the action of the mainspring 11 and pushes the strikers 12 forward with great speed. Under the action of the ventral acceleration of the strikers 12, moving forward, the capsule of the cartridge located in the breech part of the barrel C with the speed necessary to ignite the rumbling re) mixture of the capsule is shot. The rattling mixture of the capsule takes up the gunpowder in the cartridge sleeve and the bullet begins to move along the bore of the gunpowder under the action of the gas produced during combustion, the volume of which increases significantly in a short period of time. At the moment when the ball starts to move, a large force of friction between the walls of the barrel and the outer surface of the ball arises in the barrel. Under the action of frictional forces, the barrel 3, freely installed in the transverse grooves of the frame 2 and pressed by the shutter and the return spring 7 to the lower edge of the exit hole " Shutter casing 1, presses with its front part on the shutter casing 1, which in turn is pressed into the front /- from the part to the longitudinal sliding grooves of the frame 2. The frame does not have time to go down as quickly, because it is acted upon. the mass of the frame, the stop of the rod of the return spring 7, which tends to expand it in space clockwise, towards of the front part of the casing-shutter 1 and the muscle effort of the shooter who fires while holding the weapon. At this moment, friction occurs between the casing-shutter 1 and the frame 2 in the front part, which inhibits the movement of the casing-shutter 1 back. During the movement of the bullet along the bore of the barrel 3, the sleeve located in the breech part of the barrel begins to move

Ge" back under the pressure of the expanding gas. The resistance of the return spring 7, the mass of the casing-shutter 1 and the friction in the front part between the frame 2 and the casing-shutter 1 creates additional gas pressure, under the action of which the sleeve in the front

Me. part expands and creates additional friction between the walls of the sleeve and the breech part of the barrel, along which it moves back. After the bullet exits the barrel 3, the pressure in the barrel drops sharply, the frictional force in the front part of the frame 2 and the front part of the casing-shutter 1 decreases, the sleeve stops expanding and moves back already under the influence of the residual pressure and the force from the dent, which occurs at the moment "M of the shot. Due to the action of inertial forces on the parts of the gun, the force of friction in the front part between the casing-shutter 1 and the frame 2 decreases uniformly and remains almost until the end of the stroke of the casing-shutter 1, that is, until it rests against the shock absorber 16. Thus, the retardation of the movement of the casing-shutter 1 back when fired occurs due to: the action of the return spring 7 of the casing-shutter 1; the resistance of the large mass of the casing-shutter 1;

P friction in the front part of the gun between the frame 2 and the casing - shutter 1; additional friction that occurs between the walls of the sleeve and the walls of the breech part of the barrel 3.

Approximately from the beginning of the movement of the bullet to its exit from the barrel 3, the sleeve travels a distance of no more than 3 MM in a time period of 0.002 seconds. At the moment of the shot, the gun is stabilized in the horizontal plane by the mass of the moving bullet, because it, acquiring a direction under the pressure of the gas expanding at a high speed, moves directly along the axis of the barrel 3. The parts of the shutter casing 1, frame 2 move in space relative to each other not only in the horizontal, but also in the vertical planes. This is due to the fact that barrel C in this scheme is a part made of a heavier metal and, for this reason, is less susceptible to inertial forces at high 65 / SPEEDS than parts made of light alloy - shutter casing 1 and frame 2. An additional stabilizing factor is the location of the cartridge shank, which enters the rear part of the bolt body 4, while stabilizing the movement of the bolt casing 1 along the axis of the barrel bore 3. When the bolt casing 1 moves back, the following occurs: the cocking of the shock-trigger mechanism, the trigger 9, the bolt casing begins 1, which moves back, deviates back and takes the position of a combat platoon; the protrusion of the trigger pull (separator) comes out of the groove of the side wall of the casing-shutter 1 and the trigger pull 18 moves down, while the lower part of the whisperer 10, which engages with the combat protrusion of the trigger, is released; the casing is ejected, and its rear part rests against the reflector.

When the casing-shutter 1 moves to the extreme rear position (Fig. 2) due to the residual forces of inertia of the clutch 5, which 7/0 fixes the return spring 7, abutting against the shock absorber 16, stops by pushing into the frame 2. As a result of this push and action of the spring of the magazine moves the ammunition along the front inclined wall of the magazine 19 forward and up, as a result of which the upper cartridge reaches the limiting protrusions of the magazine.

At the moment when the cover-shutter 1 rests in the frame 2, the gun tilts slightly upwards, but within the limits that allow control to be maintained. Under the action of the return spring 7, the casing-shutter 1 returns to the original 7/5 position (Fig. 1) and at the same time a reloading cycle takes place - the cartridge is sent into the chamber, the trigger pull 18 becomes the upper projection opposite the cutout in the side wall of the casing-shutter 1. Enough release the trigger 8 and the trigger 18 under the action of the spring engages with the sear 10. The forward movement of the casing-shutter 1 occurs without a jerk, because the compressed return spring 7 is partially blocked by the shock absorber 16. Under the action of the mass of the casing-shutter 1 moving forward , and the natural tension of the balls of the shooter's hand, the gun returns almost 2o to the initial position, at which the previous shot was fired. The novelty consists in the following: the casing-shutter of the barrel and the frame are made of light alloy; partial braking of the bolt roll occurs due to the dynamic interaction of the parts of the gun during the shot, which is due to the design, fastening and location of the parts themselves - the barrel, frame, casing-barrel shutter and the return spring of the casing - barrel shutter; the device contains the original design of the casing shock absorber - barrel shutter; the fastening of the trigger, the axis of which is the transverse rod of the trigger pull, is simplified; "the body of the gun is made taking into account modern design requirements; the design of the body and parts has no analogues and is an independent development; when replacing the barrel, bolt and magazine, it is possible to use a pistol for cartridges of different caliber, length M and purpose. from pr so
