Description

The invention relates to the field of weapons technology, in particular to self-loading pistols.

The design of the P4 pistol "Storm" of the company "Beretta" / "Fedoseev SL," All about the gun ", 2003, M., LLC" Publishing house AST ", p.205-243 / with locking by turning the barrel with the entry is known a locking protrusion into the extraction window and a spring-loaded barrel closure against which the barrel abuts during a rollback, thereby damaging the barrel’s impact on the frame when unlocking. This design allows partial shock absorption during unlocking, but does not provide shock attenuation at the extreme rear point of shutter rollback and when the shutter is in the front position.

The design of the gun “Pernach” I. Ya. Stechkina / “Fedoseev S.L.,“ All about the gun ”, 2003, M., LLC AST Publishing House, pp. 205-243 /, in which the shutter is again engaged, is known with a spring-loaded barrel at the end of its recoil, which largely extinguishes the impact of the shutter on the frame at the extreme rear point of the moving parts. The disadvantage of this design is the use of a free shutter, which makes it impossible to use powerful cartridges.

Also known is the design of the gun company Glock Austria / Fedoseev S.L., "All about the gun", 2003, M., LLC "Publishing house ACT", pp.205-243 / with firing trigger mechanism with cocking drummer and setting it to whisper at the end of the shutter lag period.The disadvantage of this design is the unreliable operation of the trigger mechanism in the conditions of pollution.

The design of the GSh-18 pistol is also known. Russia / SL Fedoseyev, “All About the Pistol”, 2003, M., ACT Publishing House LLC, pp. 205-243 / also with a trigger trigger mechanism and cocking the firing pin at the end of the shutter kickback period. A disadvantage of this design is that the shutter strikes against the frame in extreme forward and extreme rear positions.

The objective of this invention is to provide a relatively compact and lightweight self-loading pistol with high accuracy and high reliability of the automation by reducing the impact of the shutter on the frame in its extreme rear position due to the re-engagement of the shutter and barrel at the end of the shutter retraction period after extraction of the sleeve, and the rolling shutter should will move the barrel and compress the spring of the barrel lock, which should significantly reduce the shutter recoil speed without affecting the operation of the automation. In addition, the placement of the sear in the bolt and the cocking of the striker in the initial period of the rollback should also increase the reliability of the automation, and the preservation of the idling of the barrel after it is locked in combination with the presence of a rubber shock absorber should weaken the shock in the extreme forward position. All these measures together should reduce the total recoil momentum and thereby increase the accuracy of fire.

The essence of the invention consists in creating a self-loading pistol, consisting of a barrel, a frame, a shutter, a magazine, a barrel lock, a spring of a barrel lock, a return spring, a whisper, a trigger, an interpreter-fuse, a striker, a cocking lever of a striker, characterized by the presence on the inner surface of the shutter of two symmetrical protrusions, the location of which is selected from the condition of their contact with the locking protrusions of the barrel at the end of the shutter recoil period after passing a distance sufficient for extraction of the shot sleeve, by placing a return spring around the barrel lock, placing the barrel spring in the inner cavity of the barrel lock, placing the sear and translator-fuse in the bolt behind its mirror, the axis of the translator-fuse also being the axis of the sear, having a protrusion on the trigger that has the ability contact with the hammer, and the location of the protrusion is selected from the condition of preventing contact of the hammer with the capsule of the cartridge when the trigger is incomplete, as well as the fact that the reciprocal the position of the drummer and the sear is selected from the condition of placing the drummer on the battle platoon of the sear in the period of joint rollback of the barrel and the bolt until they are disengaged.

The present invention - a gun - consists of a frame / 1 /, a trunk / 2 /, a store case / 3 /, a store bottom / 4 /, a store supply spring / 5 /, a feeder / 6 /, a shutter case / 7 /, a front sight / 8 /, rear sight / 9 /, return spring / 10 /, guide return spring - barrel lock / 11 /, barrel lock spring / 12 /, sear / 13 /, sear spring / 14 /, fuse translator / 15 /, drummer / 16 /, the mainspring / 17 /, the trigger / 18 /, the trigger spring / 19 /, the cocking lever of the striker / 20 /, the body of the trigger mechanism / 21 /, the slide delay / 22 /, the magician’s latch Ina / 23 /, the ejector / 24 /, the ejector spring / 25 /, and a safety protrusion on the trigger / 26 /. The guide of the return spring - the barrel lock with its springs are placed on under the barrel, the sear with its spring is placed in the bolt behind its mirror, there is also a two-way fuse translator, and its axis is the axis of the sear. The slide delay is located behind the magazine, the magazine latch is at the base of the trigger guard, the trigger and the cocking lever of the hammer interact with the pin. The barrel has two symmetrical protrusions / 27 /, the upper of which enters the shutter extraction window / 28 /, and the lower one interacts with the barrel lock when unlocking and with the protrusion of the lock / 29 / when locking. The barrel also has two symmetrical side windows near the muzzle end / 30 / and a front diaphragm / 31 /, into which the flow of powder gases emanating from the barrel windows is impacted, thereby inhibiting it. The shutter also has two symmetrical lateral protrusions in its front part / 32 /, with the help of which it engages with the locking protrusions of the barrel at the end of its recoil period. The sear has a protrusion for interacting with the trigger / 33 /, a protrusion for holding the striker in the cocked position / 34 / and a protrusion for interacting with the flag of the translator-fuse / 35 /. The on-off translator locks the shutter, trigger and sear in the on state.

Before the shot, the cartridge is in the barrel / 2 /, the magazine / 3 / is inserted into the handle, the barrel / 2 / is engaged with the bolt / 7 /, the return spring / 10 / and the spring of the contactor / 12 / are in a minimal compression. When firing self-cocking, the trigger / 18 / rotates the cocking lever of the striker / 20 /, he pushes the striker / 16 / back and puts it on the sear / 13 / and then the trigger / 18 / overturns the sear / 13 / with his ledge and fires a shot. When cocked drummer cocking lever drummer idles. The trigger spring / 19 / is placed vertically in the frame between the trigger and the magazine, with its lower end being used as the magazine latch spring / 23 /.

After the shot, the bolt / 7 / with the hammer / 16 / and the barrel / 2 / begin to roll back, compressing the return spring / 10 /. Having passed a distance sufficient for the gas pressure in the barrel to fall, they interact with the barrel locker / 11 / and the barrel / 2 / starts to turn, making a rotation of 60-90 degrees when unlocked. In this case, the barrel / 2 / and the shutter / 7 / begin to compress the spring of the contactor / 12 / and their speed drops. The drummer / 16 / by inertia continues to move backward, overtaking the bolt, and, having traveled a distance of no more than 1/2 the length of the cartridge used, becomes a sear. / 13 / After uncoupling the barrel / 2 / and the shutter / 7 /, the barrel still continues to move backward for some time, compressing the spring of the contactor / 12 /, due to which its impact on the frame / 1 / is largely extinguished. The shutter / 7 / under the influence of recoil also continues to move backward and after extraction of the spent sleeve, which is reflected on the protrusion of the bolt stop / 22 /, again interacts with the barrel / 2 /, which by that time had returned to the position at the moment of unlocking under the action of the spring contactor / 12 /. Together they reach the extreme rear position, and due to the increase in mass and the addition of another spring, the shutter blow to the frame is largely absorbed.

When returning to its initial position, the shutter / 7 / captures the next cartridge, again engages with the barrel / 2 /, the rotation of which is carried out by the interaction of the lower locking protrusion with the protrusion on the inner surface of the frame. The residual impact of the shutter in the extreme forward position is extinguished by a polymer shock absorber / 36 /. After a new pull on the trigger, the cycle repeats, when the cartridges are used up, the shutter becomes on the shutter delay / 22 /. The safe descent of the striker / 16 / with a combat platoon is carried out by pressing down the flag of the translator-fuse / 15 /. At the same time, the sear is squeezed out of its protrusion, the drummer is released, and then, under the action of the sear spring / 14 /, it returns to the "Fire" position. A special protrusion of the trigger / 26 / does not allow the drummer to pass a sufficient distance to strike the capsule.

The presence of a gas barrel brake allows for reliable operation of automation when using cartridges with a significant dispersion of power.

Cocking the drummer in the initial period of the rollback seems optimal from the point of view of reliability, since it is during this period that the moving parts of the automation have the greatest energy.

Placing the sear with the spring in the shutter makes it possible to optimize the distribution of mass, since the sear is involved in creating the shutter mass.

All parts of the trigger mechanism are mounted in the housing using pins, axles and screw connections are not used in the design of the gun.

The movement of the barrel after unlocking and the joint movement of the barrel and the shutter after the extraction of the sleeve allow the shock-free operation of the automation without compromising the reliability of its operation and extending the life of the weapon as a whole by attenuating the shock loads.

The presence of a safety protrusion on the trigger allows you to do without an internal automatic fuse, which also simplifies the design of the gun.

Using the return spring guide as a spring-loaded barrel lock allows to simplify the design of the gun and at the same time increase the mass of the moving parts during the recoil period of the bolt, which allows to slightly reduce its mass while maintaining the total mass of the mobile system.

Along with a reduced recoil momentum, the main advantage of this design is its relative simplicity - the gun consists of only 25 parts versus 33 parts for the Makarov pistol and 34 parts for the Glock-17 pistol.
