Description

The utility model relates to small arms, in particular to stocks, and can be used in sports biathlon rifles designed for sports target shooting in open and closed shooting ranges.

The box of small arms according to the patent RU 2256142 C1 is known in the prior art, in which the box contains an adjustable cheek located at the end of the butt, which has a U-shaped cross section, and a butt plate, while in the butt there is a groove in which the cheek latch is installed, which on two sides has grooves, one of which includes the base of the cheek with a through groove. In this case, the butt plate has a base lock, which has a dovetail groove and a horizontal slot, and in the back of the butt there is a butt plate guide with a butt plate holder on which concentric grooves are made.

The disadvantage of this device is:

1. Low operational characteristics of this product, such as low rigidity and high wear of the bed at the junction of the recoil paw due to the use of softer materials (in particular wood);

2. The heavy weight of the rifle, in view of the use of heavy materials, which cannot be changed. Fluctuates from 3.5 to 4.3 kg;

3. It is not possible to adjust and change the balance and parameters of the bed for a particular shooter, as an athlete-shooter receives a rifle in the standard version:

- butt plate and cheek butt are adjustable in a very narrow range;

- unregulated stand under the grip of the left hand from the "standing" position is built into the configuration of the box;

- there is no change in the angle of the grip of the front arm for the "lying" position;

- there is no possibility of selection of the required butt length;

- there is no possibility of shifting the butt plate axis.

As the closest analogue to the prototype, the box of the multi-shot rifle according to the patent RU 2605040 C2 is adopted, in which the box contains the front and back parts, the front part of the box being connected to the back part in a detachable manner by means of a plug-in connection that contains an inserted element located in the front of the box, and a receiving device corresponding to the inserted element in the form of a slit in the back of the box.

The disadvantages of the prototype is:

1. Low operational characteristics of this product, such as low rigidity and high wear of the bed at the junction of the recoil paw due to the use of softer materials (in particular wood);

2. The heavy weight of the rifle, in view of the use of heavy materials, which cannot be changed. Fluctuates from 3.5 to 4.3 kg;

3. It is not possible to adjust and change the balance and parameters of the bed for a particular shooter, as an athlete-shooter receives a rifle in the standard version:

- butt plate and cheek butt are adjustable in a very narrow range;

- unregulated stand under the grip of the left hand from the "standing" position, built into the configuration of the box;

- there is no change in the angle of the grip of the front arm for the "lying" position;

- there is no possibility of selection of the required butt length;

- there is no possibility of shifting the butt plate axis.

The following essential features common to the prototype were identified for the claimed device: Small arms stock containing front and rear parts connected to each other, while the front part is made in the form of a forearm.

The technical problem of the claimed utility model is the elimination of these disadvantages of the prototype, namely the improvement of reliability and strength; reducing the weight of the bed and increasing ergonomics, as well as increasing the convenience of operation and tuning the performance of the rifle for a particular athlete-shooter (depending on anthropometric indicators and the athlete’s own forces).

The technical problem is solved in that the small arms bed containing the front and rear parts connected to each other, while the front part is made in the form of a forearm, differs from the prototype in that the front and rear parts are made in the form of a truss frame of aluminum alloy, the front part equipped with an adjustable arm stand for the shooter when shooting from the “lying” position with a grip-adjusting mechanism and a place for the store’s shaft, the back of the box is equipped with an adjustable arm arm platform for shooting from the position “Standing” with a grip-adjusting mechanism, an adjustable butt plate with a guide and a butt pad lock and an adjustable butt cheek with a cheek lock, as well as an anatomical pistol grip with a lengthwise stroke. Additionally, the front and rear parts have holders for storing magazines and places for installing belt fasteners, such as swivels.

Brief Description of the Drawings

The technical nature and principle of operation of the proposed bed are illustrated in figure 1, which shows the bed in a schematic representation, and figure 2 - axonometric.

The implementation of the invention.

In FIG. 1 shows a box of small arms, for example, a sports biathlon rifle, composed of front 1 and rear 2 parts of the box. Both parts are made of high-strength alloy based on aluminum, for example, aviation duralumin grade B95T2, to give maximum rigidity and lightness to the structure as a whole, as well as in the form of a truss frame forming an external skeleton of the structure (Skeleton type), protecting internal mechanisms with strong walls "Farms". In this case, the internal mechanisms remain partially open, visible through special openings (windows).

The front part 1 is used to install a barrel in it with a breech block with a trigger mechanism (trigger) and is the forearm of a rifle (not shown in Fig.). The breech section is laid in specially grooved for this place radial shape, since the breech section (box) of the rifle itself is made rounded, and fixing takes place with two screws.

The front part 1 is equipped with:

- mine 15 for installing a breech block with a USM rifle;

- stand 3 for the left hand of the shooter to shoot from the “lying” position from the belt with a mechanism 4. The mechanism 4 changes the athlete’s grip under the left hand, taking into account the anatomy of his hand. Stand 3 is made, for example, of wood; Also in the place of the grip there is a t-shaped passage 13 for attaching the Antabok mechanism;

- place 5 under the mine shaft store.

The rear part 2 of the lodge serves as a stock and an attached grip located on it. The back of 2 is equipped with:

- landing hole 16 of the mounting rod of the adjustable platform 17 under the left hand for firing from a standing position. The platform 17 is located in front of the protection of the trigger guard (Fig. Not shown);

- an adjustable butt pad 6 with a guide 7 and a retainer for the base of the butt pad 8. The butt pad 8 of the butt is also made of aluminum alloy, for example, aviation duralumin. The recoil pad 8 increases the ergonomic quality of the weapon, reduces the load on the shooter's shoulder during firing, increases the stubborn quality of the stock, and also allows you to adjust the moment of pressing the stock, taking into account the anatomical features of the shooter;

- an adjustable cheek of the butt 9 with a clamp of the cheek 10. The cheek of the butt 9 allows you to conduct a uniform aiming, limiting the pressure on the head of the shooter at the time of aiming at one stable height. Depending on the anatomical features of the shooter, there are several settings for the height of the butt cheek 9 and movement along the horizontal plane;

- an anatomical pistol grip 11, having a stroke along the length, to configure a comfortable grip. The handle 11 is made, for example, of wood;

- also on the rear part 2 is the swivel 14 for attaching the transfer belt.

The front 1 and rear 2 parts are connected to each other by a screw connection: The rear part 2 is attached to the front part 1 with three screws. The first screw through the shaft shaft of the adjustable stand 3 under the left hand, the second screw is under the trigger mechanism, the third screw is on the outside of the front of the 1 bed to the rear 2.

In addition, the front 1 and rear 2 parts have holders 12 for storing magazines (cartridge clips) rifles with magnetic locks, made, for example, of plastic.

The bed undergoes preliminary bead-blasting treatment (cold forging), which additionally increases the strength characteristics of the surfaces of the bed itself, as well as electrochemical painting (anodizing).

The technical result of the invention is:

- frame construction (such as Skeleton) allows you to make the product of the most durable materials, which gives maximum rigidity without increasing the weight of the product, which also allows you to make the use of this product as efficient as possible;

- Improving ergonomic qualities and reducing the weight of the athlete’s weapons as a whole, which will affect the overall performance of both biathlete shooting and an increase in skiing speed (by reducing the weight of the portable rifle, unlike the standard version). In addition, the weight of the rifle can be changed in a wide range depending on the anthropometric indicators of the athlete-shooter, but does not exceed 3500-3800 grams (within the framework of the rules of the sport - at least 3500 grams);

- an athlete-shooter receives a box for a rifle with customization capabilities (a butt plate and cheek adjustable in a wide range) for his anthropometric features of the body structure (arm length, neck length, etc.);

- the bed is made of duralumin alloys, which gives rigidity and minimal wear during operation.
