Description

The utility model relates to weapons technology, namely firearms.

A firearm taken as a prototype is known from the state of the art (hunting carbine “145 Los”. Operating manual. 2020. https://kalashnikov.market/product/32019/baikal-145-los-.308-win-550-mm -orex-shag-narezov-255), containing a firing device and a stock. The connection between the receiver and the stock is detachable.

As a disadvantage of the known weapon, it can be noted that the firing device can be completely separated from the stock and used for criminal purposes. This contradicts the Forensic requirements for the technical characteristics of civilian and service weapons, as well as ammunition for them (approved on June 7, 2022), according to which the weapon should not have a design that allows, without irreversible changes, to make its length less than 800 mm and maintain the ability to produce shot.

The purpose of the utility model is to expand the arsenal of firearms.

The technical result consists in creating a firearm with an integral connection between the stock and the firing device while maintaining operational characteristics by providing access to maintenance of the trigger mechanism.

The technical result is achieved in that the firearm contains a stock and a firing device installed in the stock, in which, according to the utility model, the shooting device is integrally connected to the stock with the possibility of vertical movement and rotation relative to the stock. The firing device can be connected to the stock using an elongated part, the first end of which forms a rotational pair with the shooting device, and the second end forms a rotational pair with the stock.

The essence of the utility model is illustrated by the following drawings.

Figure 1 - weapon with the firing device in the upper position.

Fig. 2 - remote element displaying the connection of an elongated part with a firing device and with a stock.

Fig. 3 - cross-section of the weapon at the junction of the elongated part with the stock and the firing device in the upper position.

Fig. 4 - weapon with the firing device in the lower position.

The weapon contains a firing device 1 and a stock 2 with a forend 3 (Fig. 1). The shooting device 1 is installed in the seats (not shown) of the stock 2 and contains a receiver 4 with a barrel 5 fixed in it, a trigger mechanism 6, a bolt 7. The shooting device 1 is permanently connected to the stock 2. In this case, the shooting device 1 has the ability make a complex movement, which includes movement in the vertical direction and rotation relative to the stock 2. The complex movement of the shooting device 1 is performed along the axis of the stock 2.

Next, we will consider an example of a utility model, in which the complex movement of the shooting device 1 is realized by connecting the stock 2 with the shooting device 1 using an elongated part 8, which forms rotational pairs (hinges) with the shooting device 1 and with the stock 2, respectively. Thus, the first end of the elongated part 8 is connected to the firing device 1 to form a rotational pair (hinge), and the second end of the elongated part 8 is connected to the stock 2 to form a rotational pair (hinge).

In the example considered below, a support 9 is installed on the barrel 5 to connect the first end of the elongated part 8 with the firing device 1 (Fig. 2, 3). However, a variant of the receiver 4 is possible, in which the first end of the elongated part 8 is connected to the body of the receiver 4. Also in the example considered below, the second end of the elongated part 8 is connected to the rear part of the forend 3 (Fig. 1). However, depending on the design features of the shooting device 1, the stock 2 and the elongated part 8, the latter can be connected to the stock 2 at any point.

At the first and second ends of the elongated part 8 there are holes 10, 11 for pins 12, 13, respectively (Fig. 2, 3). In this case, the diameter of the holes 10, 11 is greater than the corresponding diameters of the pins 12 and 13 to create 8 rotational pairs (hinges) with the forend 3 and the firing device 1. The elongated part 8 is placed in the grooves 14, 15 of the support 9 and the forend 3, respectively, and is connected to support 9 and forend 3 using pins 12, 13, respectively. The pin 12 is installed in the holes 16, 17 of the side walls of the support 9 (Fig. 3). The pin 13 is installed in the holes 18, 19 of the side walls of the forend 3. The holes 17, 19 are made blind, and the pins 12, 13 are installed in the holes by pressing, which ensures a permanent connection between the stock 2 and the firing device 1.

When the firing device 1 is in the upper position (Fig. 1), the ends of the elongated part 8 are placed in the grooves 14, 15 of the support 9 and the forend 3, respectively. When the firing device is in the lower position (Fig. 4), part 8 is completely placed in the groove 15 of the forend 3, and the first end of part 8 is additionally in the groove 14 of the support 9.

The connection of the shooting device 1 with the stock 2 is one-piece, which excludes the independent use of the shooting device 1 to fire a shot.

The ability of the firing device 1 to move in a vertical direction while simultaneously rotating relative to the stock 2 provides the user with space sufficient for maintenance of the trigger mechanism 6 (cleaning, lubrication, etc.).

In the considered example of a utility model, the movement of the firing device 1 in the vertical direction occurs due to the fact that the part 8 is made of an elongated shape and forms a rotational pair (hinge) with the firing device 1. And the rotation of the shooting device 1 relative to the stock 2 occurs due to the fact that the stock 2 and the elongated part 8 form a rotational pair (hinge).

To improve performance characteristics and prevent possible dismantling of the elongated part 8, the ends of the pins 12 and 13 are made flush with the side surfaces of the walls of the support 9 and the forend 3, respectively.

Placing an elongated part 8 in the groove 15 of the forend 3 (in the position of the firing device in the lower position) maintains the streamlined shape of the weapon and eliminates accidental snagging of equipment elements, user clothing, etc., preventing injury to the user.

The connection of the elongated part 8 with the rear part of the forend 3 provides the optimal length of the lever, allowing to minimize the displacement in the transverse direction when lowering the firing device 1 to the lower position, which facilitates the assembly of the weapon.

To carry out maintenance work, it is necessary to separate the magazine (not shown), move the bolt 7 back and remove it. Then grab the firing device 1, remove the trigger mechanism 6, receiver 4, barrel 5 from the seats (not shown) of the stock 2, raise the firing device 1 to the upper position (Fig. 1). In this case, the firing device 1 will move vertically upward and rotate relative to the point of connection of the second end of the elongated part 8 with the stock 2, opening maximum access to the trigger mechanism 6. After completing the maintenance work, lower the firing device 1 to the lower position, placing the shock - trigger mechanism 6, receiver 4, barrel 5 into the seats (not shown) of stock 2. Install the bolt 7 and the magazine (not shown).

The creation of a firearm with an integral connection between the stock and the firing device allows for the unhindered use of the declared utility model on the territory of the Russian Federation. At the same time, the operational characteristics of the weapon are ensured due to the availability of access to maintenance of the trigger mechanism due to the fact that the firing device has the ability to move in the vertical direction simultaneously with rotation relative to the stock.
