Gun stock

FIELD: weapons and ammunition.

SUBSTANCE: stock of small arms like "bullpup" automatic weapon with a carriage is made based on a metal enveloping guide for a moving firing unit with possibility of its preliminary roll-out to perform a "fixed string" of three-four shots. Bends of the enveloping guide of the stock, which face each other, are equipped with upper longitudinal ribs with possibility of enveloping the bends. Elements facing downwards and arranged on lateral sides of the metal base of the firing unit prevent movement to sides of bends of the enveloping guide of the gun stock. On lower surface of the enveloping guide stock from the nose piece of the back plate and to the muzzle part, which envelopes from below the guide stock of a cross piece, there arranged are two strengthening longitudinal stiffeners forming side walls of a collar of a lower longitudinal window in the middle part of the stock for lower sleeve ejection. In the muzzle part of the stock there formed are side connection elements for arrangement under the fore-end of "bayonet-knife" attachment elements or an under-barrel-mounted grenade dispenser, which are attached onto the guide gun stock.

EFFECT: improving stiffness of a gun stock and reducing deformation loads at shooting.

The invention relates to weapons, in particular to the boxes of small arms, and can be used in lapeirousia machine layout “bullpup” advanced recovery “shooting unit, for the production of “fixed” queue of three or four shots. Moreover, using standard tubular rifle cartridge is a smaller caliber, and are ejected downward through the lower longitudinal window guide Lodge weapons, protective cap which is placed between parallel, left and right pistol handles.

It is known device (see patent RF №2350884, the earlier development of the author and of this application, Glukhov AV, Russia/ - contains guiding the box for “shooting unit lapeyrouse machine layout “bullpup” with advanced skiing out of this “shooting unit to increase subsequent rollback in the production of “fixed” queue of three or four shots, with the release of shoot shells through the lower longitudinal window box, a protective cap which is placed between the parallel handles this lapeyrouse machine.

The disadvantage of this device is irrational design guide for flexible shooting unit, requiring attachment to the polymeric base of the bed through the rivets, as well as the lack of installation when assembling the weapon, the firing Assembly for guiding the bed, with a muzzle end and the last as more rational build variants for weapons of this type.

Famous Lodge weapons /see patent RF №2450234, another design by the author and this application Glukhov AV, Russia/ - which is the closest analogue to the technical nature of the claimed object, since the guide bed is made of all-metal, and as one with the other elements of this lapeyrouse machine, in particular a transverse sleeve hinge “lock rear position of the firing unit; metal bases, parallel pistol handles; “flange bottom longitudinal open this box for the lower release liner; shifted to the left, lower receiver box “main” store, as well as the bottom and walls state the left longitudinal “pocket” is used to pass with the movements of the “shooting unit, placed on it, is a permanent box “intermediate” shop small capacity, equipped with its own lever feeder cartridges; and a metal component is made as one with the right side bracket sighting devices; socket fuse; state side walls, and a back plate napravlyayus what about the Lodge weapons, and its upper and lower entabeni for fastening gun belt, with accommodation under the forearm of the elements of the universal mounting for the bayonet-knife, or grenade launcher. Open with the muzzle end of the guide bed, covering his items for “shooting unit, in combination with an additional feature referred to “lock in the rear position of the firing unit, and simultaneously limiter his way, allows the installation of a firing unit when assembling the weapon with the muzzle of this guide bed lapeyrouse weapons.

The disadvantage of this device is incomplete use of opportunities to improve the rigidity of the metal component of the guide bed, covering mobile “firing unit”, and therefore experiencing significant deforming load when firing, as lapeyrouse machine, and its under-barrel grenade launcher, and also having lower longitudinal box to the bottom release liner, sliding on the increased length /when three or four shots in a “fixed” queue/ “shooting unit.

The technical objective is to maximize the stiffness of the guide bed for lapeyrouse machine layout “bullpup” advanced recovery “is resusage unit”, and bottom are ejected at the increased cooldown “firing unit's weapon.

The technical result is achieved by the fact that the bed of small arms - type lapeyronnie machine layout “bullpup” is based on the metal covering rail rolling stock “shooting unit, with the ability to pre protruding past for the production of “fixed” queue of three or four shots when zoomed rollback “shooting unit and ejected down through the lower longitudinal window mentioned covering rail, polymer protective cap which is placed between the left and right pistol handles weapons, and as one with a metal covering guide is made: behind the fore end, a transverse sleeve hinge “lock rear position the firing unit is relative to its guide bed; metal base pistol handles; shoulder, placed around the perimeter of the bottom longitudinal box - guide bed; shifted to the left, the receiver for the lower box the “primary” weapons shop; bottom and the breech wall, the left longitudinal “pocket” is used to pass with the movements of the “shooting unit, placed on the last, constant box “intermediate” store - m is Loy capacity, with its own lever applicant cartridges; the right side bracket sighting devices, and placed in the last slot of the fuse; the breech side of the metal wall, and the recoil of the weapons, as well as upper and lower swivel - mount gun belt and placed under the forearm of the elements of the universal mounting for the bayonet-knife, or grenade launcher, and there are open with the muzzle end of a metal component of the sending of the bed, his covering elements to the corresponding elements of the metallic base rolling “shooting unit qualifier rollback which are vertical side tabs”, placed on the eyes hinge referred to “lock in the rear position of the firing unit, with the possibility of coupling data vertical side tabs with the corresponding lateral protrusions of the metallic base “shooting unit, these covering elements made as facing each other, “the bends”, the pilot couch, is also provided with an upper longitudinal edges with the possibility of coverage appropriate to their profile and facing down, placed on the sides of the metallic base “shooting unit elements; proactively discrepancy mentioned “is the Harbor” guide Lodge weapons, when you roll back “shooting unit in the production of “fixed” queue, also on the lower surface of the guide box, from the “toe” of the recoil pad, and to muzzle, covering bottom - guiding Lodge, jumpers polymer upper longitudinal cover weapons”posted by reinforcing two longitudinal ribs forming the side walls of the above-mentioned “flange” - “lower longitudinal window are ejected, and the lateral connecting elements placed under the fore mentioned items “universal mount” for “bayonet-knife, or grenade launcher, in addition referred to “embracing the longitudinal edges of the bends” - the sending of the bed, the side facing down - elements made as one solid metal “basis firing unit”, consisting of: receiver - carrier left side of the box “intermediate” store, sleeve chamber of the barrel with the slot wear-resistant liner; “bottom of the window, and the left axis for hinge lever follower “intermediate” store; grenade” console element rigidly connected with the right side of the “gas pipe-stem” to reduce the “resonance” of the last firing, also having a muzzle dust cover placed at the upper edge of the stop for the return spring, she is - “shock rollback - firing unit's weapon.

Distinctive features of the aggregate exhibit a new property - the possibility for covering the “firing unit” elements - in the form of inverted to each other “bends” guide Lodge weapons, the upper longitudinal edges, with the possibility of their coverage, appropriate to their profile and facing down, the elements are made as one, with a metal base “shooting unit” weapons. At the same time, in the form of reinforcing elements on the lower surface of the carrier “firing unit” - almost its entire length, has two longitudinal ribs, in the middle part of the “smart box” arms forming the side walls of the “shoulder” available “lower longitudinal window”used for the lower release liner.

The technical result is ensured by the fact that the alleged additional items placed on the carrier “firing unit,” the guide bed lapeyrouse machine, allow to maximize the rigidity of the latter, without adding any separate parts, through elements performed as one already existing.

The invention is illustrated by drawings, where: Figure 1 shows the position advanced “smart box” in the General layout of weapons, side view, left; n is 2 shows the profile section a-a, with Figure 1.
