Description

The invention relates to small arms, grenade launchers, and specifically to grenade launchers.

A 40 mm under-barrel grenade launcher M203 (USA) for assault rifles and a method for firing from a grenade launcher are known (see http://warweapons.ru/podstvolnyiy-granatomet-m203-ssha/). The under-barrel grenade launcher consists of a moving barrel with a casing rigidly fixed on it, a body of a firing mechanism. The casing provides for longitudinal movements of loading a grenade launcher, locking the barrel and cocking the trigger mechanism.

To carry out a shot from a grenade launcher, a grenade launcher is mounted on assault rifles, charged from the breech. The shot is made by pressing the trigger with the index finger of the shooter’s hand, grasping the rifle magazine. When firing an assault rifle with a grenade launcher mounted on it, the barrel casing performs the function of the forearm.

The disadvantages of this device and method are low performance, namely the inconvenience of connection due to the need for significant disassembly of the rifle for attaching a rifle grenade launcher, as well as unreliable holding of the rifle to the magazine during firing of a weapon with an attached grenade launcher.

Known 40 mm grenade launcher GP-34 for Kalashnikov assault rifles and a method for firing from a grenade launcher (see http://zonwar.ru/granatomet/podstvol/GP-34.html). The grenade launcher includes a barrel, a bracket for attaching a grenade launcher to small arms, firing mechanism, translator. The grenade launcher has a hollow rubber grip to hold the weapon when firing from a grenade launcher.

To carry out a shotgun from a grenade launcher, a grenade launcher is mounted on the barrel of an assault rifle on a T-shaped protrusion of the gas chamber pad by means of a T-slot in the front of the bracket and an automatic grip of the assault rifle with the back of the bracket fixed to the forearm, fixed with a latch, charged from the muzzle. The shots are made by pressing the arrow with the index finger of the hand while grasping the rubber grip, while under the action of the combat spring the trigger vigorously turns up and strikes the striker, the striker moves up, smashing the ammunition igniter cap, the shot occurs.

The disadvantages of this device and method are:

- low performance, namely the inconvenience of holding the weapon when firing from a machine gun with a grenade launcher attached to it, since the grenade launcher completely covers the machine gun forearm and has angular shapes and protruding parts in the place of holding the weapon, as well as the inconvenience of holding the weapon when shooting from machine gun grenade due to lack of rigidity and height of the rubber grip, while the height and rigidity of the handle are determined by the condition of free accession to the automatic atu store;

- the inconvenience of maintenance due to the significant effort that is applied when you press the trigger with the index finger of the arrow.

The technical objective of the claimed invention is to improve the performance of small arms with an attached grenade launcher by increasing the ease of retention and maintenance and quick installation of a grenade launcher on the weapon.

The technical result consists in the convenience of holding, redistributing the force applied to the launch of the grenade launcher from the index finger to the whole hand of the shooter and the free connection (detachment) of the magazine to the small arms.

This goal is achieved by the fact that the under-barrel grenade launcher for small arms consists of a barrel, a bracket for attaching a grenade launcher to small arms, a translator, a firing mechanism, including a spring-loaded trigger, a trigger and a combat spring. On the barrel of the grenade launcher mounted casing, made with the possibility of longitudinal movement and connected to the descent by means of an axis, on the casing is a spring-loaded latch key. The latch key is located on the right side of the casing or on the left side of the casing. The latch key is installed in the bosses, made in the upper part of the casing. At the front end of the casing there is an annular shoulder. On the casing there is a groove for the emphasis of the interpreter for blocking. The bracket is made protrusions to attach to small arms. In the lower part of the casing there is a groove in which the ejector is placed.

This goal is achieved by the fact that the method of making a shot from a grenade launcher includes installing a grenade launcher on a small arms, loading ammunition, removing a grenade launcher from an interpreter, and making a shot. After the grenade launcher is removed from the interpreter, the casing is moved back while simultaneously holding the latch key, while descending through the thrust rotates the trigger, the combat spring is compressed, and the trigger breaks down from the trigger, then the trigger returns to its original position under the action of the combat spring. The casing is blocked in the stowed position with the help of a translator, which rests on a groove made on the casing. The casing is blocked in the firing position using the latch key, which rests against the front end of the bracket.

The invention is illustrated by drawings, which depict:

in fig. 1 - a general view of small arms with an attached grenade launcher;

in fig. 2 is a longitudinal section of a grenade launcher;

in fig. 3 - a general view of a grenade launcher;

in fig. 4 - a general view of the casing.

The under-grenade launcher 1 to the small arms 2 contains the barrel 3, the bracket 4, the movable casing 5, the firing mechanism 6. The bracket 4 is mounted on the barrel 7 of the small arms 2. The casing 5 is mounted on the barrel 3 and is connected by an axle 8 with the trigger 9, spring-loaded 10 descent. On the grenade launcher 1 installed translator 11, blocking the casing 5 in the stowed position. The casing 5 has a streamlined shape, closes the body and protruding parts of the grenade launcher and provides the convenience of holding weapons. On the casing 5 are made bosses 12, in which a spring-loaded latch key 13 is installed, abutting against the front end of the bracket 4 and blocking the movement of the casing 5 in a combat position. Spring-loaded key 13 of the lock is installed on the right side of the casing 5 or on the left side of the casing 5 of the grenade launcher. To prevent the hand from slipping, the shooter has a shoulder 14 on the front end of the casing 5. The casing 5 has a groove 15 which serves to stop the interpreter 11 to block the casing 5 in the stowed position. On the casing 5 there is a hole 16 in which the axis 8 is installed, and a groove 17 in which an ejector 18 is installed, designed to extract the ammunition from the bore 3 of the grenade launcher 1. On the bracket 4 there are projections 19 for connecting with the receiver 20 small arms 2, the axis 21 of the grenade launcher 1 is fixed in the capital box 20. The trigger mechanism 6 of the grenade launcher contains thrust 22, trigger 23, drummer 24, combat spring 25. To prevent a shot from a grenade launcher 1 not attached to small arms 2, it is provided spring-loaded This fuse 26 turns off upon contact with the barrel 7 of small arms.

To install an under-barrel grenade launcher, the axle 21 is removed, the forearm (not shown) of the small arms 2 is removed and the grenade launcher 1 is installed instead. The projections 19 of the grenade bracket 4 will enter the receiver box 20, and the front part of the bracket 4 will cover the barrel 7 of the small arms, in this case, the fuse 26 is turned off. Attached grenade launcher 1 fixed axis 21.

To fire a grenade launcher 1, load a grenade launcher 1 with ammunition, transfer translator 11 into a firing position by lifting it up to release casing 5. Grip the casing 5 of the grenade launcher with your hand, push the spring-loaded key 13 of the retainer with your thumb and hold the casing 5 back until it stops. In this case, the casing 5 through the axis 8 interacts with the descent 9 of the grenade launcher 1, moving it back and compressing the spring 10 of the descent. Simultaneously, the descent 9 through the attached with him 22 turns the trigger 23 with the drummer 24 back and compresses the combat spring 25. At the end of the rotation, the trigger 23 is thrown off the ledge of the thrust 22 and under the action of the combat spring 25 returns to the front position, pinning the ammunition cap 24. Shot occurs. After the shot, the casing 5 returns to the forward position under the action of the spring 10 of the descent 9.

Thus, the proposed device and method make it easy to install a grenade launcher on a small weapon instead of a forearm, increase retention when firing from both small arms and a grenade launcher attached to small arms, to redistribute the force applied to the launch of the grenade launcher from the index finger on the whole hand an arrow and freely attach (detach) the shop to small arms.
