Description

The invention relates to weapons, in particular to small arms lodges, and can be used in a bullpup layout monitor with preliminary roll-out of the “firing unit”, for producing a “fixed” line of three to four shots. Moreover, using a standard automatic cartridge case - reduced caliber, and ejecting cartridges - down through the lower longitudinal window of the guiding bed of the weapon, the protective neck of which is placed between the parallel, right and left pistol arms.

Known device / cm. RF patent No. 2350884, an earlier development of the author and of the present application, AV Glukhova, Russia / - containing a guide bed for a “firing unit” of a bullpup layout machine with a preliminary roll-out of this “firing unit” to increase subsequent rollback in the production of a “fixed” line of three or four shots, with the ejection of spent cartridges through the lower longitudinal window of the bed, the protective neck of which is placed between the parallel arms of this carriage but.

The disadvantage of this device is the irrational design of the guide for the movable “firing unit”, requiring fastening to the polymer base of the bed by means of rivets, and the lack of the possibility of installation - when assembling weapons, firing unit on the guide bed, from the muzzle end of the latter - as a more rational assembly option for weapons of this type.

Known weapon box / cm. RF patent No. 2450234, another development of the author and of the present application A.V. Glukhova, Russia / - which is the closest analogue in technical essence to the claimed object, because the guide bed is made of all-metal, and combined with other elements of this carriage, in particular the transverse sleeve of the hinge “firing unit rear position lock”; metal bases of parallel pistol grip; “Flange of the lower longitudinal window” of this bed - for the lower ejection of cartridges; shifted to the left, the receiver of the lower box-shaped “main” store, as well as the bottom and breech walls of the left longitudinal “pocket” - which serves as a passage for the movement of the “firing unit” placed on it — a permanent box-shaped “intermediate” store - of small capacity, equipped with its own lever feed cartridge; as well as the metal component is made integrally with the right side bracket of the sights; fuse socket; breech side walls, and the back plate of the guiding bed of the weapon, and its upper and lower swivels for fastening the gun belt, with placement under the fore-end of the universal fastening elements for the “bayonet-knife”, or under-barrel grenade launcher. Moreover, open from the muzzle end of the guiding bed, its covering elements - for the “firing unit”, in combination with the additional function of the said “locking device for the rear position of the firing unit”, and at the same time the limiter of its roll-out, allow the installation of the firing unit - when assembling weapons, with the muzzle parts of this guide lapel of the gun weapon.

The disadvantage of this device is the incomplete use of the possibilities of increasing the structural rigidity of the metal component of the guide bed, covering the movable “firing unit”, and accordingly experiencing significant deforming loads when firing, both the gun carriage and its underbarrel grenade launcher, and in addition, having a lower longitudinal window for the lower ejection of shells, rolling to an increased length / with three to four shots in the “fixed” line / “shooting of the unit. "

The technical task is to maximize the stiffness of the guide bed for a bullpup layout carriage with a preliminary roll of the “firing unit”, and lower ejection of cartridges with an increased rollback of the “firing unit” of the weapon.

The technical result is achieved by the fact that the bed of small arms — such as a bullpup-mounted carriage assembly made on the basis of a metal enclosing guide — for a movable “firing unit”, with the possibility of preliminary rolling out the latter to produce a “fixed” line of three or four shots, with increased rollback of the “firing unit” and the ejection of shells down through the lower longitudinal window of the said enclosing guide, the polymer protective neck of which is located between Ava pistol grip and the left arms, and integrally with a metal covering rail are made: placed behind the fore-end, the transverse pivot sleeve "position adjustable fastener firing unit" - with respect to its guide bed; metal bases of pistol grips; “Shoulder located around the perimeter of the lower longitudinal window” - guide bed; shifted to the left, the receiver for the lower box-shaped “main” weapons store; the bottom and breech walls, the left longitudinal “pocket” - which serves as a passage for the movements of the “firing unit”, located on the last, constant box-shaped “intermediate” magazine - of small capacity, with its own lever feed cartridge; the right side bracket of the sighting device, and the fuse socket located at the base of the last; breech side metal walls, and the recoil pad of the weapon, as well as the “upper and lower swivels” - mounts of the gun belt, and elements of universal mount located under the forend for the “bayonet-knife”, or under-barrel grenade launcher, and there are metal components of the guiding bed open from the muzzle end , its covering elements - for the corresponding elements of the metal base of the movable “firing unit”, the rollback limiter of which are the “vertical lateral protrusions” placed on the eyes of the ball the aforementioned “locking position of the rear position of the firing unit”, with the possibility of coupling these vertical side protrusions with their corresponding side protrusions of the metal base of the “firing unit”, while the said covering elements are made as facing “bends” to each other, on the guide bed, also equipped with upper longitudinal ribs with the possibility of their coverage, corresponding to their profile and facing down, placed on the sides of the metal base of the “firing unit” - e by the elements preventing the divergence of the said “bends” of the guiding bed of the weapon during the rollback of the “firing unit” during the production of the “fixed” line, also along the bottom surface of the “guiding bed, from the“ toe ”of the butt plate, and to the muzzle, covering the bottom of the guiding bed, jumpers - polymer “upper longitudinal cover of the weapon”, reinforcing longitudinal two stiffening ribs are placed, which also form the side walls of the said “shoulder” - “lower longitudinal window” for ejecting sleeves, and side connecting elements nts for the mentioned “universal mount” elements placed under the fore-end for a “bayonet-knife”, or under-barrel grenade launcher, in addition, the aforementioned “covering longitudinal ribs of the bends” - the guide bed, the lateral downward - elements are made integrally with the all-metal “firing base” unit ”, consisting of: a receiver - supporting the left side box-shaped“ intermediate ”store, barrel chamber bushings - with a socket for a wear-resistant liner; “Bottom window”, and the left half shaft - for the hinge of the lever feeder of the “intermediate” store; under-barrel ”cantilever element, rigidly connected to the right side“ trunk gas pipe ”to reduce the“ resonance ”of the latter when firing, also having a muzzle dust shield located at the upper rib-stop for a return spring, it is also a“ recoil shock absorber - firing unit "Weapons.

Distinctive features in the claimed combination show a new property - the ability to place on the elements covering the “firing unit” - in the form of “bends” of the guiding bed of arms facing each other, upper longitudinal ribs, with the possibility of their coverage already corresponding to their profile and facing downwards elements - made integrally, with the metal base of the “firing unit” of the weapon. At the same time, in the form of reinforcing elements, two longitudinal stiffeners are placed on the bottom surface of the carrier “firing unit” — almost the entire length of it; in the middle part of the “guide bed” of the weapon they form the side walls of the “shoulder” of the existing “lower longitudinal window” serving for lower ejection of cartridges.

The technical result is ensured by the fact that the declared additional elements placed on the carrier “firing unit”, the guide bed of the carriage, make it possible to maximize the rigidity of the latter, without adding any separate parts, by means of elements that are made together with existing ones.

The invention is illustrated by drawings, where: Figure 1 shows the position of the improved “guide bed” in the overall layout of the weapon, side view, left; figure 2 shows a profile section aa, with figure 1.

The weapon box contains / cm. Figure 1-2 /: “carrier” - 1, for the movable “firing unit”, type - covering the guide ”of the latter, its“ lower longitudinal window ”- 2 for the lower ejection of sleeves having a“ polymer protective neck "- 3, placed between parallel pistol arms, and also shown: forend - 4; hinge transverse sleeve - 5, “firing unit rear position lock” - 6; metal bases of pistol grip - 7; “Shoulder” - 8, along the perimeter of the “window” / 2 /; receiver - 9 for the lower box-shaped “main” store - 10; bottom and breech walls - 11, of an available longitudinal “pocket” - 12, which serves for the passage of a permanent box-shaped “intermediate” store - 13, located on the “firing unit”, and having its own “lever cartridge feeder” - 14; right side bracket - 15 sights - 16; “Fuse socket” - 17; breech side walls - 18, and butt plate - 19 weapons; swivel - 20 for fastening the gun belt; universal fastening elements - 21 “bayonet-knives”, or under-barrel grenade launchers; open “muzzle end” - 22 carriers / 1 /, for attaching a “firing unit”; covering elements / by the type of bends facing each other / - 23 on the "carrier" / 1 /; the corresponding “covered bends” - 24 on the metal basis of the “firing unit”; “Vertical lateral protrusions” - 25, of a hinged “lock of the rear position of the firing unit” / 6 /, as limiters of the latter to roll out when they are coupled to their respective side protrusions - 26 “of the base of the firing unit”; “Upper longitudinal ribs” - 27, located on the “bends” / 23 /, and covering them, covering the side elements - 28 “the basis of the firing unit”; parallel longitudinal “stiffeners” - 29 along the lower surface of the carrier ”/ 1 / of the guiding bed of the weapon. Also shown: muzzle covering jumper - 30 “upper longitudinal covers” - 31 weapons; lateral connecting elements - 32 for elements of “universal fastening” / 21 /; making up the "basis of the firing unit": receiver - 33; sleeve - 34 for the chamber - 35 barrel - 36 weapons; “Wear-resistant insert socket” - 37; also, the “bottom window” - 38; left axle shaft - 39 “articulated feeder cartridges” / 14 /; “Under-barrel cantilever element” - 40, and its rigid connection - 41, with the right side “gas pipe” - 42 weapons; “Muzzle dust shield” - 43, at the “upper rib” - 44 serving as a stop for the “return spring” - 45, it is also the “shock absorber of the recoil of the moving firing unit” - this weapon.

The operation of the claimed improved weapon guide bed having maximum rigidity is ensured by additional “upper longitudinal ribs” / 27 / placed on the covering “bends” / 23 / - “carrier” / 1 /, made as the main element of the all-metal weapon guide bed. Moreover, these “ribs” / 27 / are also covered by their corresponding “covering side elements” / 28 / of the aforementioned metal “base of the firing unit”, forming a sliding joint, and anticipating the divergence to the sides of the “bends” / 23 / during movements of the “firing unit” - for an extended recoil length, in the production of a “fixed” line of three to four shots, accompanied by significant dynamic loads on the said metal “covering carrier” / 1 / - movable “firing unit”. Also, the two parallel lower “stiffeners” / 29 / of the given weapon bed prevent the deformation of the latter both under the influence of the recoil of the under-barrel grenade launcher and in the bayonet strike in close combat. An additional advantage of this design is the possibility of emphasis when shooting from unstable positions, the lower part of the free pistol grip of the “bed” - on the elbow bend, the arrow hands holding the forearm of the weapon. At the same time, lateral “stalling of arms”, having a lower box-shaped “main” store shifted to the right, is prevented due to additional support.
