Description

SUBSTANCE: invention relates to weapons technology, namely to weapons for hunting and sports shooting for use in normal mode, in experimental or training shooting.

Well-known single-shot bolt rifles are easy to load and chamber (see the book "Sporting and hunting small arms", author Markevich V.E., Polygon, St. Petersburg, 2005, http://hunter02.ru/images/feafares/ Sportivnoe-i-ohotniche-strelkovoe-orughie.pdf). The cartridge is inserted in front of the extended bolt, and then the bolt is moved forward, introducing the cartridge into the chamber. A multiply charged weapon is known in which the supply of cartridges to the ramming line is carried out from the store (see the book "Sporting and hunting small arms", author Markevich V.E., Polygon, St. Petersburg, 2005, http://hunter02.ru /images/features/Sportivnoe-i-ohotniche-strelkovoe-orughie.pdf).

Unlike single-shot weapons, there are delays in magazine systems due to improper feeding of cartridges, while in single-shot shotguns such delays are eliminated due to a simpler device.

In some cases, there is no need, and sometimes, the possibility of feeding a cartridge from the magazine, for example:

- the cartridge used has an oversized bullet, which makes it impossible to use a regular magazine, you need to have separate magazines for different cartridges and, in addition, it takes a lot of time to change the magazine;

- training and experimental firing, requiring single shots of various ammunition, and reloading the magazine with one cartridge takes more time than using a single-shot weapon system, etc .;

- in order to acquire shooting skills within two years, it is possible to own only single-shot weapons, tk. in accordance with the current legislation, citizens of the Russian Federation, before the expiration of the first two years of possession of a long-barreled firearm, are not allowed to acquire, for the purposes of self-defense or hunting, a smooth-bore long-barreled firearm with a magazine (drum).

Known multi-shot weapon TK-503 with an attached magazine (http://techcrim.ru/?page_id=16760) (https://zen.yandex.ru/media/guntest/tk-503-novyi-paradoks-ot-tehkrima- 620ba225fe15ff1d9bbb4bd4, publ. 02/17/2022), adopted as a prototype, contains a barrel with a chamber, a sliding bolt, a housing with a receiving window and an extraction window. A regular store is installed in the receiving window.

The disadvantage of the known weapon is the inconvenience of handling the weapon due to the increase in the time it takes to prepare the weapon for firing, for example, when using various cartridges, the impossibility of safe use of the weapon by beginners in shooting (does not meet the conditions for the possession of weapons by beginners with an experience of less than 2 years).

The objective of the claimed invention is to improve performance, incl. by converting a multi-shot firearm into a single-shot weapon with the ability to manually load any cartridge allowed by the design of the weapon, excluding the installation of a magazine, which, among other things, will satisfy the condition of novice possession of weapons "firearms, smooth-bore long-barreled weapons should not have a magazine."

The problem is solved due to the fact that the firearm, containing a barrel with a chamber, a sliding bolt, a housing with a receiving window and an extraction window, according to the invention, is equipped with a cartridge receiving device for manually feeding one cartridge, rigidly fixed in the receiving window of the housing. The device for receiving the cartridge can be made in the form of a tray. The device for receiving the cartridge can be equipped with a device for closing the opening of the receiving window of the body. The device for receiving the cartridge can be made in the form of a trough with a downward concavity in cross section.

The declared single-shot weapon, converted from a multi-shot weapon, has improved operational characteristics. Placement in the receiving window instead of the store of the device for loading the cartridge manually eliminates the possibility of delays in the use of one weapon in different situations, for example, for experimental or training firing. In this case, it is possible to feed the cartridge manually through the extraction window in the position of the shutter in the rearmost position, the weapon can be loaded with only one cartridge and, therefore, can fire only once after loading, i.e. ensures maximum safety of use. A rigidly installed device for receiving a cartridge does not allow removing it from the weapon without irreversible changes associated with damage to parts or destruction of their connections. The use of a multi-shot weapon in single-shot mode with a rigidly installed device for receiving a cartridge will allow, in addition to the advantages listed earlier, inexperienced shooters to master the skills of shooting with manual feeding of a cartridge in single-shot weapon mode. A weapon with a device for closing the opening of the receiving window of the body will protect it from dust and dirt, thereby improving performance, in addition, the said device additionally prevents unauthorized attempts to install the magazine in the receiving window. The implementation of the profile section tray will ensure the supply of the cartridge to the chambering line without distortions and sticking, which in turn also improves the operational characteristics of the weapon.

The claimed invention is illustrated by drawings, which show:

fig. 1 - general view of the weapon in the context;

fig. 2 - view A in Fig. 1 with an open opening of the receiving window;

fig. 3 is a section I-I in FIG. 2;

fig. 4 is a bottom view of the weapon with the opening of the receiving window closed.

The weapon contains a barrel 1 (Fig. 1) with a chamber 2, a sliding bolt 3, a body 4 with a receiving window 5 and an extraction window 6. Inside the receiving window 5 in the body 4 of the weapon is blocked by a device for receiving a single cartridge in the form of a tray 7 of profile section (Fig. 2, 3). A cartridge is inserted through the extraction window 6 and a spent cartridge case is ejected.

Tray 7 is installed at a distance and fixed, for example, on two or more welded points 8, which makes it impossible to remove the tray without destroying it, which in turn will comply with the condition for using weapons for beginners in accordance with the legislation of the Russian Federation and ensure the safe use of weapons. The tray 7 for its positioning on the body 4 can be equipped with wings 9. Wings 9, using the existing stop 12 for a standard store in the receiving window 5 on the body 4, limiting its position from above, allow you to give the desired position to the tray 7 for fixation without distortion. In this case, to protect against dust and dirt, the window opening can be closed with a device 11, for example, a plug or a decorative strip (Fig. 4). When using a decorative strip, it can be fixed on the bed 13, for example, with fasteners 10.

The claimed weapon works as follows.

To fire a weapon with tray 7, it is necessary to pull the bolt 3 back until it stops in the rearmost position. When this occurs, the cocking of the trigger mechanism of the weapon (not shown). After that, through the opened extraction window 6 on the tray 7, the cartridge is manually placed with a bullet forward in the direction of the barrel 1. Then the shutter 3 is manually moved forward. In this case, the shutter 3 pushes the cartridge lying on the tray 7 forward into the barrel 1. When the shutter 3 arrives in the extreme forward position, the cartridge enters the chamber 2. The weapon is ready to fire. After the shot is fired, the shutter 3 is retracted. In this case, the spent cartridge case is removed by the bolt ejector from the chamber and, having bumped into the reflector, is extracted outside the weapon. The weapon is ready to receive the next round and the next shot.

The use of the claimed invention, which makes it possible to convert a multi-shot weapon into a single-shot weapon in a simple way, provides an improvement in operational characteristics.
