Description

The invention relates to weapons, in particular to gun mounts capable of being rolled back and returned to the combat position, and can be used in individual small arms automatic launchers, with the possibility of three shots - in a “fixed queue”, when the lower box-shaped magazine is stationary , weapons - made in the bullpup layout.

Known gun installation / magazine "Weapon", No. 3 - 2001, p. 2-9, see description: "5.45 mm experimental machine gun AS, prototype for AN-94, designer Nikonov G.N ., "Izhmash", Russia /, which is an individual small arms weapon of the "gun-mounted machine-gun" class, with the possibility of producing a "fixed burst" of three shots - when placing "standard" machine-gun cartridges in the lower box magazine "/ and, in this case - rolling.

The disadvantage of this device is the significant weight and size characteristics of a movable firing unit moving with the said store, which significantly impairs the operational characteristics of this weapon. In this case, the side window of the weapon, which serves to eject / ejection / cartridges, increases the likelihood of contamination, as well as the "traditional" layout of this weapon / with front - lower magazine / requires a folding butt / to reduce the length of the weapon in its stowed position /, which requires an even greater increase in the number of parts, further complicating the design of the gun-mounted weapon.

A well-known gun installation / source is the same, p. 2-9, see description: "5.45 mm experimental machine" TKB-0146 ", designer I. Stechkin. Tula Design Bureau, Russia /, which is the closest analogue in technical the essence of the declared object, as it is an individual small arms weapon of the carriage type, executed in a bullpup layout, with the lower box magazine stationary when firing, and also without a side ejection window - for ejecting cartridges.

The disadvantage of this device is the small length of the "rollback" for a movable firing unit of weapons in firing mode, the "fixed burst", which allows only two shots / in a fixed burst / and only if the rate of fire is very high / up to 2000 rds / min /, which in turn greatly complicates the choice of the kinematic diagram of the ammunition supply device for a carriage that has a lower box-shaped box that is stationary when firing, and also has a front ejection mechanism for this weapon and shells not only complicates the design, but also worsens the ventilation / cooling / conditions of this weapon having a closed "guide bed" / casing / for a movable "firing unit". In addition, this arrangement / with a removable cover, and an internal return mechanism - a firing unit located inside the guide bed of the weapon / significantly complicates the operating conditions of the weapon, for example for incomplete disassembly - in the field.

The technical task is to increase the operational characteristics of the gun installation, which is a cassette machine - bullpup layout.

The technical result is achieved by the fact that the gun mount, allowing rollback and return to the firing position, which is an individual small arms of the class carriage, made in the layout of the bullpup, with the lower box magazine stationary when shooting, and a spring-loaded firing unit sliding inside the guiding bed is made with the ability to produce a fixed burst of at least two shots, and there is an automatic lock rear position firing agr a hand-driven arrow, with the possibility of moving the released firing unit forward relative to the said weapon store and the possibility of feeding cartridges to the firing unit from the given store, with the rear firing unit of the given weapon locked, which has a bent transverse hinge connecting the above open a guide bed with its upper longitudinal cover carrying a spring return mechanism of the firing unit, and a stationary one when firing, controlling the bolt handle of the bolt assembly, as well as the ramrod socket, in addition, there are a pair of pistol fire control sticks between which the muzzle of the lower ejection window of the weapon passes, the breech of this window passing next to the store located in its receiver with lateral displacement - from the vertical plane of the weapon and with the rotation of its bullet part to the chamber of the latter, the aforementioned locking device of the firing unit is a spring-loaded “dog” placed on the transverse hinge the latter automatically engages with the corresponding element on the lower surface of the firing unit, when moving the latter manually, or under the action of recoil to its rear position in the guide bed, there is a double flag of the said dog, placed in front of the said pair of fire control sticks, with the ability to control - turn off this dog, with the thumb - the arrow hands holding one of the pair of arms mentioned above, in addition, for manual removal in the rear position firing unit on the muzzle device of the latter there is a vertical bracket equipped with a protective thermally insulating coating, and to reduce the load on the mentioned finger, the arrow, said tooth of the locking dog engages with a roller element placed on the transverse axis, inside the corresponding hole - the bottom of the receiver of the firing unit of this weapon .

Distinctive features in the claimed combination exhibit a new property - the possibility of introducing into the design of the carriage of small arms a latch for the rear position of the firing unit with the possibility of its automatic operation each time the latter is moved to the rear position to load the existing additional intermediate magazine from the main magazine / lower box /, fixed at shooting. Moreover, it is possible to turn off this latch using the thumb of the right or left hand of the shooter holding one of the two available fire control arms of a weapon having a bullpup layout with a lower ejection window, as well as placing a number of structural units on the hinged upper longitudinal cover.

The technical result is ensured by the fact that the presence of an automatic lock of the rear position - the firing unit of a bullpup assembly weapon allows us to solve the problem: to increase the length of the recoil in a wielded weapon of this configuration / bullpup / by preliminary moving the spring-loaded firing unit forward while disabling its mentioned lock. In this case, the following possibilities appear: an increase in the number of shots in a fixed line up to three to four / when using "low-pulse" cartridges, for example, 5.45 mm, arr. 1974 / or the use of "full-caliber" machine-gun cartridges in this weapon / 7.62 mm, arr. 1943 /, with two shots in a fixed queue, by increasing the length of the recoil of the firing unit. At the same time, in the fixed rear position of the latter, the length of this weapon will be about 700 mm, providing high compactness / and accordingly maneuverability / of the latter, with the possibility of automatic and single fire with a stationary firing unit. In addition, the placement of this latch on weapons with lower ejection shells allows you to simultaneously adapt the latter for firing from both the right and left shoulders, without complicating the ejector mechanism of the weapon, and the placement of a number of weapon nodes on its hinged upper longitudinal cover increases ease of use, for example in case of incomplete disassembly - in the field, when this weapon can be located on the gun belt - on the neck of the shooter, with minimal risk of contamination.

The invention is illustrated by drawings, where in Fig.1 shows the General layout of the gun installation, which is a cuffed bullpup layout machine, with a lower fixed magazine, side view, left; figure 2 horizontal section aa - figure 1; figure 3 profile section bB of figure 1.

The gun mount contains / cm. 1-3 / automatic lock of the rear position of the firing unit 1, which has a transverse hinge 2, a figured "fork" flag 3, a return spring / torsion / 4 and a hook 5, interacting with a roller element 6 placed on its transverse axis 7 A movable firing weapon assembly is also shown, comprising a barrel 8, a receiver 9, a barrel-shaped profiled bracket 10 with a muzzle vertical bracket 11, a bolt assembly 12, a side intermediate magazine 13 and its own spring-loaded cartridge feed 14 and springs This return mechanism 15 for the bolt assembly / 12 /. It also showed a guiding bed 16 of a weapon, containing a pair of pistol fire control levers 17, a lower ejection window 18 passing between them, having side walls 19 of its neck 20, connected by means of lower transverse jumpers 21 to the arms 17, there is also a receiver 22, for stationary when shooting lower box / main / magazine 23, offset from the vertical plane of the weapon; placed above the forearm 24 is a vertical arch-shaped element 25, a bent lateral hinge 26, and a reinforced rubber "butt plate" 27 of the weapon guide bed open at the top. Also shown is the hinged upper longitudinal cover 28 of the latter, bearing the spring return mechanism of the firing unit 29; the handle of the spring-loaded bolt frame 30 that is stationary during shooting and the jack for the ramrod 31, as well as the muzzle latch of the cover 32 and the block of the sighting device 33. Also shown are the side axles 34, the guide bed 16 and the longitudinal oval eyes 35 of the cover 28, which form a breech-mounted weapon hinge, also shown is a longitudinal protective bracket 36 for said handle 30 and a socket for accessory 37, a detachable connection 38 of the return mechanism 29 and the firing unit.

Gun installation works as follows. The convenience of covering any of the two arms of the arms 17 is provided due to lateral displacement of the latter, one to the right and the other to the left of the vertical plane of the weapon. In this case, the side walls 19 of the neck, of the lower ejection window 20 protect the hand of the shooter, covering one of the said arms 16 from the ejected sleeves. Moreover, the increase in the length of the rollback / shown by the arrows in Fig. 1 / for the movable spring-loaded firing unit / 8-15 / is provided due to the preliminary forward movement of this unit, under the action of its spring return mechanism 29, placed on the upper longitudinal cover 28, which by means of a breech cross the hinge 34, 35 is connected to the guide bed 16 of this weapon. At the same time, the loading of the side intermediate magazine 13 on the firing unit equipped with its own cartridge suppressor 14 is carried out in the rear position of this unit from the main lower box magazine 23, which is stationary when firing, installed in its receiver / 22 /, with lateral displacement from the vertical plane of the weapon due to features of the last ammunition supply device / operation of this "device" - not to be given, because the latter was prepared by the author for patenting as an independent application for an invention. Moreover, the aforementioned rear position for the firing unit is fixed - with the possibility of automatic and single fire / with direct feed of the cartridge to the chamber from the main magazine through an intermediate magazine /. And for the production of a fixed burst / 3-4 shots, depending on the power of the cartridge used /, the automatic locking of the rear position lock is carried out - the firing unit 1-5, coupled to the roller element 6 mounted on the under-barrel bracket 10 mounted on the transverse axis 7, and this connection provides a small load on the thumb arrow; simultaneously holding the handle 17 of the weapon and by means of the said finger acting on the figured fork-shaped flag 3 of this latch. In this case, in the production of a fixed line under the action of recoil, the firing unit comes to its rear position inside its guide bed 16 and is fixed in it by means of the aforementioned latch, made like a dog. Also, to manually divert this firing unit to its rear position, a vertical bracket 11 having a thermally insulating coating is placed in the muzzle of the profiled underbarrel bracket 10 - firing unit of this weapon.

The claimed device, which is a cassette bullpup layout machine with a lower box magazine fixed when firing and an automatic lock for the rear position of the firing unit with the ability to manually disable the latter, can increase the number of shots in a fixed line up to three or four, depending on the recoil energy of the cartridge used. At the same time, there is the possibility of automatic and single fire, in the rear position - inside the guide bed, moving forward, a spring-loaded firing unit of weapons, which provides compactness / about 700 mm length / and, accordingly, maneuverability for this carriage weapon with the possibility of lower ejection of cartridges.
