Abstract

FIELD: small arms. SUBSTANCE: automatic handgun has a scope, housing/bolt, firing mechanism, magazine, movable barrel with return spring installed on it. One end of the spring rests on the scope. The second end of the scope rests on housing/bolt. When the bolt comes back the barrel and bolt are moved together being interlocked with a closer. As they moves further, wedge rests on scope projection and displaces rear part of the closer. Barrel hole unlocking occurs. Return spring is compressed as it rests. Forward motion starts under action of return spring due bolt release. Closer comes over the barrel, channel is locked and the bolt together with barrel are moved forward up to the rest on the barrel. EFFECT: high rate of fire. 2 cl, 1 dwg

Description

 The invention relates to small arms, in particular to self-loading pistols, and is aimed at improving their design.

 Known automatic pistols, selected as analogues of the invention.

 One of these pistols is a German 9-mm pistol [1] containing a frame, a bolt with a trigger mechanism, a magazine, a movable barrel, a barrel locking mechanism and two return springs located on the sides of the frame. The principle of operation of the automatics with recoil of the barrel during its short course was used and, in addition, a locking wedge is used to lock the barrel channel.

 Closest to the technical solution to the invention is a 9-mm Italian pistol [2] containing a frame, a bolt with a trigger mechanism, a magazine, a bolt, a locking mechanism, a movable barrel and a return spring located under the barrel. Automation pistol based on the use of recoil energy with a short course of the barrel. The locking system is based on the operation of the locking wedge that connects the bolt to the barrel.

 The location of the return spring on the barrel is widespread in pistols with free locking of the bore, using low-power cartridges. Pistols for powerful cartridges, as was shown in the analogues, have a rigid locking of the barrel and return springs are located under the barrel or to the side of the barrel.

 The disadvantage of analogues of the invention is that the location of the return springs under the barrel or to the side of the barrel leads to an increase in the dimensions of the weapon and, in addition, does not provide sufficient uniformity in the distribution of the force of the return spring along the bolt.

 The subject of the invention is the design of a self-loading pistol under a powerful cartridge.

The main objectives of the invention are as follows:
improving the reliability of the gun due to the uniform distribution of the forces of the return spring along the bolt and the central application of forces relative to the guides;
reduction in the size of the gun;
improving operational characteristics, consisting in the simplicity of disassembling and assembling weapons, reducing the number of parts and simplifying their configuration.

 To achieve this goal, it is proposed to install a return spring on the movable barrel, and place a stop on the frame on which the rear end of the return spring mounted on the barrel rests. Moreover, the front end of the spring rests in the casing shutter. One of the embodiments of the invention may be the following: the emphasis is removable and a protrusion is made on it to fix the barrel delay.

 The location of the spring on the movable barrel reduces the size of the gun and contributes to the even distribution of the spring forces at the inlet of the shutter.

 The drawing shows the design of the proposed self-loading pistol.

 It consists of a frame 1, a shutter housing 2, a trigger mechanism including a hammer 9, a trigger 3, a trigger 10, a magazine 4, a movable barrel 5, a locking mechanism including a wedge 6 and a contactor 11, a return spring 7, a magazine latch 12 The frame is equipped with a stop 8 with a protrusion 13, interacting with the barrel delay 14.

 The work of parts and mechanisms of the gun during firing is as follows.

 To load the gun into its handle, you need to insert an equipped magazine, take the bolt to its extreme rear position and release it. When the bolt is retracted back, the barrel and the bolt move together, locked together by a contactor. With further movement, the wedge abuts against the protrusion of the frame 15 and shifts the back of the contactor downward, the locking protrusions of the contactor disengage from the bolt and the barrel channel is unlocked. With further movement, cocking is triggered. After the falling protrusion of the shutter passes behind the magazine, the magazine spring will feed another cartridge to the delivery line. The return spring, resting against the stop, is compressed. When releasing the shutter under the action of the return spring, it will begin to move forward, sending the cartridge into the chamber.

 After the cartridge is completely sent into the chamber, the contactor, slanting at the barrel delay, raises its rear part, and the locking protrusions of the contactor go beyond the side stops of the shutter. The barrel is locked. The bolt together with the barrel moves forward until the barrel stops in the barrel delay.

 To fire a shot, you must press the trigger. In this case, the trigger strikes the hammer and breaks the igniter cartridge, a shot is fired. Under the action of recoil, the bolt and barrel move backwards, doing the same work of the gun as when loading.
