Description

The invention relates to weapons, in particular to small arms, such as a bullpup-mounted carriage with a preliminary roll forward relative to the “guiding bed” of the weapon, the spring-loaded “firing unit” of the latter, with the possibility of increasing the length of the subsequent rollback of the “firing unit” in the manufacture of “fixed ”Line of three or four shots, depending on the type of used“ cartridge ”automatic cartridge.

Small arms are known / Kalashnikov magazine, No. 1/2004, pp. 10-16; see description: “5.45” - mm pilot-operated machine gun “TKB-0146”, designer I. Stechkin, Russia /, containing a return spring mechanism for the “firing unit” of the weapon mounted inside the “guiding bed” made in the layout Bullpup.

The disadvantage of this device is its inadequacy for the bullpup layout carriage, the spring-loaded “firing unit” of which, to increase the length of its recoil, in the firing mode the “fixed” queue / 3-4 shots / is preliminary moved “rolls” forward relative to the said “guide” bed "of this weapon.

Small arms are known / cm. patent for invention 2370721 - an earlier development of the author and the present application A. Glukhova, Russia /, which is the closest analogue in technical essence to the claimed object, because there is a spring return mechanism for the bullpup layout carriage moving inside the “guide bed”, its “firing unit”, which also has the ability to pre-roll forward inside the said “guide bed” weapons to increase the length of its subsequent rollback during the production of the “fixed queue” of three or four shots, depending on the type of low-pulse automatic cartridge used, the aforementioned spring return mechanism ”, it is also“ shock absorbing recoil - firing unit ”, located on the“ upper longitudinal cover ”of the weapon, in parallel with a multifunctional mechanism made on the basis of a movable“ reload handle, ”and there is a supporting element located on the muzzle of the elongated spring of this“ recoil shock absorber ”, which acts on A “vertical rib” that is present on the “under-barrel cantilever element of the said“ rifle assembly ”of the weapon, and when the said“ cover ”is disconnected from the weapon, it is kept from falling forward, together with dpirayuschey active support spring element of their "longitudinal guide sleeve" by retainer being disabled when assembling the device.

The disadvantage of this device is the need to use when assembling any guide for the said elongated reinforced spring - “shock absorber recoil firing unit”, and given the increased diameter of its turns, the ramrod of this weapon is of little use due to its own small diameter and large loads on it, when installing said spring, inside its aforementioned “sleeve-like guide” - on the “top cover” of the weapon.

The technical task is to increase the ease of assembly for the mechanism of “shock absorber rollback - firing unit" weapons.

The technical result is achieved by the fact that the small arms of the “bullpup” layout are of the type of a cuffed assault rifle, with the possibility of preliminary rolling out of their “rifle aggregate” to increase the length of the subsequent rollback of the latter, during the production of a “fixed” line of three or four shots using low-pulse assault cartridges , contains a spring “shock absorber recoil firing unit”, made on the basis of an elongated reinforced cylindrical compression spring, also located inside its from covered from the muzzle end - a “sleeve-like guide placed on the polymer“ upper longitudinal cover ”of the weapon, in parallel with another,“ multifunctional ”mechanism, made on the basis of a separate movable“ reload handle ”of the weapon, and there is its support located on the muzzle end of the said reinforced spring an element acting on passing through the lower longitudinal slot of said “sleeve-like longitudinal guide”, a “vertical rib” present on the “underbarrel element” of said firing unit ”, also a support element of an elongated spring - when disconnecting the“ upper longitudinal cover ”from the weapon, they are held together with the elongated spring from falling forward from their“ sleeve-like longitudinal guide ”by means of a latch that is disabled when assembling this device, and there is one located inside the coils the elongated spring “shock absorber rollback - firing unit” longitudinal “covered guide elongated spring, equipped with a narrowed breech with the possibility of its passage inside the coils of the elongated spring, during the rollback of the “firing unit of the weapon, and also connected to the said flange support element” - for the muzzle end of the elongated spring, with the possibility of using this “longitudinal guide of the elongated spring when assembling the mechanism of the“ shock absorber of the recoil - firing unit ”of the weapon, except Moreover, this guide of the elongated spring is hollow, and the said latch is made in the form of an axle placed on the axis longitudinal to the barrel, inseparably from the “upper longitudinal cover”, transverse about the “flag”, which in the locked position is placed in the “muzzle transverse slot” - the walls of the “sleeve-like longitudinal guide”, while partially blocking the entrance to its open muzzle end and, accordingly, preventing the longitudinal guide and the elongated spring supporting it from muzzle flange , this cross-flag is also placed on the side of the said “vertical rib of the under-barrel cantilever element”, without hindering the rollback of the movable “firing unit” of the weapon.

Distinctive features, in the claimed combination, exhibit a new property - the ability to place inside a “sleeve-like” longitudinal guide ”, placed on the“ upper longitudinal cover ”of a gun-mounted weapon, a flange-covered guide, equipped with a narrowing of its“ breech-like “part, for its passage during rollback “Firing weapon assembly, inside the coils of a reinforced“ elongated spring ”- the“ rollback shock absorber ”mechanism of this“ firing weapon ”, with the possibility of being kept from falling forward from a crumpled “sleeve-like longitudinal guide” when disconnecting the said “cover” from the “guide bed”, an assembly in the form of a flange “covered guide” and a supporting, “elongated spring” supporting it, which is carried out by means of a hinged “fixing” weapon placed on the “cover” an element engaged in the locking position with the flange of said “male guide”.

The technical result is ensured by the fact that the presence of a flange covered guide provided with a narrowing of its breech, with the possibility of passage inside the turns of the reinforced “elongated spring of the mechanism of the“ shock absorber ”for the“ firing unit ”, allows you to use this“ covered guide ”- when assembling this mechanism“ recoil shock absorber ”, for centering the“ elongated spring ”- along the axis of its mentioned“ sleeve-like ”longitudinal guide, also a simple and reliable design of inseparable from the “roof” of the arms of the aforementioned hinged “latch”, coupled to the “muzzle” flange of the “covered guide”, it is possible to reliably fix the mentioned movable components of the “roll-back shock absorber-shooting unit” mechanism inside the “sleeve-like” longitudinal guide, while simultaneously ensuring the convenience of its assembly.
