Description

The utility model relates to automatic small arms, mainly machine guns and can also be used in robotic complexes.

An automatic weapon is known in which the box with cartridges is located above the barrel, the cartridges in the box are slanted and feed back (see GB Patent GB 191516038 (A) - 1919-03-27).

A disadvantage of the known device is the limited capacity of the box, low reliability due to the high probability of jamming of the cartridge. In addition, placing the store in a known device makes the barrel heavier and makes shooting difficult.

Known machine gun M-60, containing a barrel, butt, trigger and a box with a tape located to the left side of the barrel (figure 1), however, such a mount makes the weapon unbalanced about the axis of the barrel and makes it difficult to shoot from the shoulder.

Also known is a multi-shot weapon containing a barrel, a butt, a trigger and a box with cartridges, located below the barrel, outside the section of the input window of the tape receiver and made in the form of a semicircle. This device is the closest to the proposed (see GB 127278 (A) - 1919-06-05).

A disadvantage of the known device is the limited capacity of the box, low reliability due to the high probability of jamming of the cartridge. In addition, placing the store in a known device makes the barrel heavier and does not allow balancing the weapon in the longitudinal direction, which makes it difficult to use.

The technical result expected from the use of the utility model is:

- reduction in size while maintaining the length of the barrel,

- increase the capacity of the box while maintaining the overall height,

- the possibility of aimed shooting while standing,

- reducing the time of opening fire, the ability to produce a faster shot when shooting “offhand” due to the center of mass of the weapon close to the shoulder, which simultaneously improves the controllability of the weapon and reduces the aiming time,

- increase the effectiveness of fire from unstable positions,

- an increase in the rate of transfer of fire,

- Improving the convenience of work in cramped conditions (transport, facilities, etc.).

This goal is achieved by the fact that in the known automatic weapons containing a barrel, a trigger mechanism and a box with cartridges, located below the barrel and offset relative to the Central cross section of the input window of the receiver, characterized in that the box is made with a tape, the links of which provide misalignment of the cartridge in the output the opening of the box and the input window of the tape receiver, and is fixed at an angle to the plane of the cross section of the barrel equal to the allowable misalignment of the type of tape used.

In this case, the box can be made with the possibility of adjusting the angle of inclination to the plane of the cross section of the input window of the receiver.

In addition, the box can be fixed in the position obtained by additional rotation by an acute angle around the axis of the barrel and / or perpendicular to this axis and / or the vertical axis of the box.

In this case, the distance of fixing the box from the central cross section of the input window of the receiver and the corresponding angle of inclination to the specified plane of the central cross section of the input window of the receiver can be selected based on the maximum possible approximation of the center of gravity of the box to the center of gravity of the entire device.

In addition, the device may be provided with tape guides located between the outlet of the box and the inlet window of the receiver.

In this case, automatic weapons can be made with electronic stabilization and / or aiming and / or tape feeding systems, the power supply or batteries of which are located in the additional compartment of the box, and the connection of output power buses and input buses of the said electronic stabilization and aiming systems is detachable .

Placing the box below the barrel, outside the central cross section of the input window of the receiver means that the projection of the plane of the box in which its outlet is located on the horizontal plane in which the barrel lies is offset along the barrel in this plane relative to the transverse axis of the input window of the receiver. Thus, the box with the tape is not located on the side of the input window of the tape receiver and is not located directly below it, as in the known solutions, but is shifted along the barrel relative to the input window of the tape receiver forward or backward and tilted relative to the perpendicular to the barrel so that for a given distance of the box offset when feeding the tape, the radii of bending and misalignment of the links, which are structurally acceptable for this type of belt, are provided when passing the path from the guide rails to the guides of the input window of the weapon receiver. And in the indicated displaced and inclined state, the box is fixed.

The execution of the box with the tape means that the cartridges are placed on the tape, and the tape is laid in the box with the possibility of feeding through the outlet.

The implementation of the tape with the ability to ensure misalignment of the cartridge in the outlet of the box and the input window of the receiver means that the links are made with the possibility of play or rotation relative to each other not only around the transverse axis of the tape, which provides its flexibility in the known solution, providing a bend around a short, transverse the axis or axis of the cartridge, as well as opening it with a “fan” in the plane of the tape, but also play and rotate around a “long”, longitudinal axis, so that the cartridge “rotates” relatively flat ti tape.

The permissible misalignment with respect to this type of tape and the selected displacement of the box means the sum of the tolerances for misalignment for the total number of tape links located in this case between the outlet of the box and the input window of the tape receiver (taking into account their linear displacement). In this case, the optimal angle of fastening of the box within the specified tolerance can be determined both by the average of the calculated (geometric) characteristics of the tape used, and empirically - by the criterion of maximum stability and duration of operation in difficult conditions (temperature, pollution, etc.). Moreover, the stability of work primarily means the complete absence of jamming and other effects that cause uneven movement of the tape in all modes of use of weapons.

The function of adjusting the angle of the box at a selected offset distance means the ability to adapt to the parameters (different types) of the tape without a significant change in layout.

The location of the projection of the vertical axis of the box on a plane perpendicular to the axis of the barrel at an acute angle to the perpendicular to the axis of the trunk (which lies in the specified plane) means that, while staying below the trunk, the box is rotated relative to the axis of the latter left or right, but can also be rotated simultaneously relative to said perpendicular or own axis. Moreover, for the box in a complex and asymmetric design, the perpendicular to the attachment plane or other surface on which the outlet for the tape is placed can be selected as the axis.

Figure 2 shows a General view of the proposed device. Figure 3, 4 illustrate the design of a 7.62 mm Kalashnikov machine gun PC and the proposed device in the layout of "bullpup", respectively. This was done in order to demonstrate the convenience of using the proposed arrangement of the box with cartridges in the bullpup layout, although it can also be used to modernize the machine gun in the usual layout. Figure 5 illustrates the essence of the proposal for the standard layout.

1. Box with cartridges placed on the tape

2. Standard mounting box

3. Native trigger

4. Native handle

5. Native stock

6. Handguard

15. The input window of the tape receiver.

Figure 2 also shows the hinged cover 16 of the input window of the receiver 15, which acts as a guide tape 17 with cartridges 18. The electronic aiming system is indicated by 19. Pos. 20 in FIG. 5 denotes an element for adjusting the angular position of the fastening of the box 8 and the box 1 itself. FIG. 6 schematically shows an element of the tape 17 with links 21 having mobility with respect to each other, in particular, which can rotate around axes 22 and 23.

The heirs of easel machine guns, as you know, are single machine guns, which can be fired from with a bipod, a ground machine, as well as anti-aircraft, automobile, helicopter and other installations.

One of the best modern unified machine guns is considered to be the 7.62 mm Kalashnikov PC machine gun with a quick change barrel and its upgraded versions of the PKM and PKP Pecheneg. He has repeatedly proved effective in battle. In the 80s, combat experience revealed the insufficiency of both firepower and the aiming range of full-time RPK and RPK-74 light machine guns used in the squad-detachment link, and caused the use of PKM machine guns in their version as a light machine gun (with firing from bipod). Thanks to a fairly powerful cartridge, the PKM provided the required firing range and the penetrative effect of bullets on various obstacles.

The proposed change in the design of the mounting box allows you to use the layout of the “bullpup” on machine guns with tape power, which in many cases increases the efficiency of the use of such weapons by 20-30% compared with the standard version.

The operation of the device will be considered first in a traditional layout. It is also carried out as in the well-known multiple-charge weapon, but with the difference that due to the displacement of the box 1 with cartridges 18 placed on the tape 17 by the amount L in the direction of the barrel outlet 14 and rotation relative to the axis of the adjustment element 20 by an angle α (or axis , perpendicular to the axis of the barrel 14, see figure 5) cartridges 18, being in the plane of the tape 17 at the exit from the box 1 are tilted down by the sleeve, and being in the input window 15 of the receiver (not separately highlighted in the drawings, like other standard elements of the device) parallel to barrel 14 nogozaryadnogo weapons. This is achieved due to the flexibility of the tape 17, the links 21 of which have the ability to rotate around two mutually perpendicular axes 22, 23 (Fig.6).

However, the advantages of the proposed technical solution are most fully disclosed in the bullpup layout, when using a standard set of elements (parts) for changing arms and fastenings, the weapon is converted to the form shown in Figs. 2, 4. Thus, a set of additional parts allows from a standard light machine gun to get a compact according to the “bullpup” scheme with the best technical characteristics that allow competing on equal terms with the best weapons in its class, and for some parameters, such as multi Functionality, compactness and efficiency of application - exceed them.

At the same time, even without changing the parameters of the barrel, the length decreases by about 25%, and in addition, the accuracy of firing when firing bursts increases due to linear recoil, since the axis of the bore 14 and the butt plate 13 are now on the same line.

The set of readjustment elements includes a rod 12, a casing 11 with a fire control handle 10, a trigger 9 and a trigger 7, a front forend 6, a butt plate 13, a box mount 8, while a rod 12 connects a standard trigger 3 with a trigger 7.

In the “bullpup” layout for firing, you must press the trigger 7, while the trigger rod 12 pushes the regular trigger 3, which will trigger the trigger.

In the case of using an electronic sight or electronic stabilization system, their power supplies (battery, for example) are conveniently placed in the compartment of the box 1, connecting the corresponding cables with a connector (not shown in the drawing).
