Description

The invention relates to weapons, in particular to limiters of the number of shots, and can be used in small arms of the class - “gun-mounted machine”, to limit the number of shots in a “fixed” line.

Known limiter of the number of shots / Babak F.K. “Basics of Small Arms”, Polygon Publishing House, 2003, pp. 178-179, see description: limiter for the number of shots for an automatic pistol “Beretta” 93R, Italy, which provides for the production of a “fixed” line with a given number of shots / three shots /, before emptying the weapons store.

The disadvantage of this device is the increased size of the node "limiter of the number of shots", which is made on the basis of the "rack" located inside the handle of the gun.

The known limiter of the number of shots / source is the same, p. 179-180, see description: limiter of the number of shots for the machine WZ-88 /, which is the closest analogue in technical essence to the claimed object, because it is more adapted to weapons of the “automatic” class, as well as an analogue, having an element that prevents the hammer from being exposed to the hammer after firing a predetermined number of shots in a queue, but being placed in the receiver of the weapon.

The disadvantage of this device is its inadequacy for weapons of the “carriage gun” class, the firing unit of which is equipped with an additional “intermediate” magazine, which has its own spring-loaded lever “cartridge feed”.

The technical task is to adapt the “limiter of the number of shots” - in the “fixed” line-up, to the small arms of the class - a “gun-mounted assault rifle”, which has an “intermediate” magazine — with its own lever-fed cartridges ”.

The technical result is achieved by the fact that the limiter of the number of shots in the “fixed” line, placed on the small arms of the “machine gun” class, contains an element which, after firing the specified number of shots, in the fixed line, prevents the impact of the “trigger element” on the weapon drummer this “limiter” is placed on a small-arms gun-type class small arms, the firing unit of which is equipped with its own “intermediate” magazine, with a spring-loaded cartridge feed, also yes This “limiter” is a “horizontal protrusion” located in the breech of the said lever “cartridge feeder” - facing the bolt frame, and another “vertical protrusion” - facing the “upper longitudinal cover” of the weapon having a “leading figured groove” - for of this “vertical protrusion”, while the said “horizontal protrusion” serves to engage the side wall of the receiver with the bolt frame - in the “approach” position of the latter to the chamber of the weapon, at the final moment of sending in the tronnik of the last cartridge from the said “intermediate” store, upon completion of the production of the “fixed” line - when the firing unit rolls back inside its guiding bed ”, and the bolt frame is equipped with a“ disconnector ”mechanism located on its case part, which allows it to be switched off when it is turned off position, the use of the bolt frame itself - as a linearly moving “trigger element”, to increase the rate of fire - in the “fixed turn” mode, the other referred to as “vertical the protrusion ”serves to force the lever“ cartridge feeder ”and, accordingly, to release the bolt carrier - carried out at the time of the arrival of the retractable“ firing unit ”, in its rear position, in which the upper end of the“ vertical protrusion ”, interacting with the bevel - available in the breech of the said leading groove ”, located on the“ upper longitudinal cover ”of the weapon, provides the uncoupling of the receiver wall, and the bolt, which is carried out after turning on the said“ time horschita ”, bolt frame - with a hammer, due to the interaction of the end flag -“ disconnector ”, with the“ leading groove ”- placed on the inner surface of the wall of the“ guide bed ”, while the bolt frame loses the function of the“ trigger element ”, also when the latter is engaged with the receiver of the “firing unit”, the hardened “tip” of the “horizontal protrusion” is placed in the “thrust” side hole of the wall of the “receiver”, and with emphasis on the breech portion of the “side longitudinal groove” of the shutter frame, etc. why in the horizontal projection of the latter the width of this “tip” is at least two values of the “output of the striker”, the striker having a return spring.

Distinctive features, in the claimed combination, exhibit a new property - the ability to perform a “limiter of the number of shots” without increasing the number of parts, because all elements of this mechanism are made “together” - with other elements of the weapon. Moreover, the principle of operation of the “limiter of the number of shots” - the “fixed” queue, is based on the engagement of the receiver with the bolt frame, in the “non-profit” position - the latter, to the chamber of the weapon, and the forced disengagement of these elements, which is also carried out automatically, when interacting “ vertical protrusion ”- this“ limiter ”, with its“ leading longitudinal groove ”located on the lid of the weapon.

The technical result is ensured by the fact that the “horizontal” and “vertical” constituents of the mechanism, the “horizontal” and “vertical” projections — the protrusions, are placed — are made “integrally,” with the lever “cartridge feed”, which is equipped with: located on the side wall of the “firing unit” ”, An additional horizontal“ intermediate store ”, as well as another component of this“ limiter ”, referred to as the“ leading longitudinal groove ”, is located on the inner surface of the“ upper longitudinal cover ”of this carriage of weapons.

The invention is illustrated by drawings, where figure 1 shows the mechanism of the "limiter of the number of shots" in a "fixed queue. Side view, left; figure 2 is a horizontal section aa / s figure 1 /.

The limiter of the number of shots contains located on the lever “cartridge feeder” 1 / Fig. 1, 2 / “horizontal protrusion” - 2, equipped with a “tip” - 3, and “vertical protrusion” - 4, interacting with the “leading limit groove” - 5 having “breech bevel” - 6, and placed on the inner surface of the “upper longitudinal cover” - 7, covering the “guide bed” - 8 from above, for the movable “firing unit”, the components of which are: “separate box” - 9, equipped with “Side hole” - 10, for the passage of the “tip” / 3 /, as well as a combat horizontal “intermediate” magazine - 11, vertical “side axis” - 12, for a lever “cartridge feeder” / 1 / equipped with a return spring / torsion / 10, also shown: a chamber - 14, a rotary shutter - 15, equipped with a “drummer” - 16, having a “return spring” - 17, “bolt frame” - 18, equipped with a “lateral longitudinal groove” - 19, for the end face of the “tip” / 3 /, and placed in the breech of the latter, node of the “disconnector mechanism” - 20, equipped with an “end flag” - 21, located in the “leading longitudinal groove ”- 22, available on the inner surface of the side wall, the“ guide bed ”/ 8 /, which also houses the“ lower main magazine ”- 23, also shown: standard cartridges / with a metal sleeve / - 24, of this weapon.

Limiter of the number of shots - in the “fixed” queue it works as follows. In the production of a “fixed” line, with a given number of shots - for example, three shots, cartridges / 24 / - into the chamber / 14 / the weapons are fed from the lateral “intermediate” magazine / 11 / located on the “firing unit”, which is equipped with its own hinged / lever / cartridge feeder / 1 / having a “return spring / torsion / - 13 and placed on the“ vertical axis ”/ 12 /, with the possibility of automatic loading of this“ intermediate ”store / 11 /, from the lower“ main ”store / 23 / , rear / relative, guide mode / position of the “firing unit”, which before the production of the “fixed” line moves forward inside its “guide bed” / 8 /, with the possibility of a significant increase in the “length of failure” - in the firing mode the “fixed” line / detailed description of the two-stage “feeder ammunition ”is not given, because earlier it was executed by the author as an application for an invention - No. 2007137281 /. Moreover, at the final stage, sending to the chamber / 14 / - the last cartridge from the side “intermediate” magazine / 11 /, located in the breech of the lever “cartridge feeder” / 1 /, “horizontal ledge” / 2 / - with its “tip” / 3 /, located in the side hole / 10 / of the “receiver” / 9 /, engages the latter with the bolt frame / 18 /, provided with a lateral longitudinal groove / 19 / for the end of the said “tip”.

In this case, the bolt frame / 18 / is fixed in the “non-profit” position to the chamber / 14 / of the weapon, losing its function of the linearly moving “trigger element”, which in the firing mode is “fixed” in turn by the “mechanism” assembly located on this “bolt frame” disconnector ”/ 20 /, which provides coupling / and disengagement / of the latter with the hammer / 16 /, equipped with a return spring / 17 /. A detailed description of the percussion mechanism / based on this “disconnector” / is also not carried out, because this device / as well as the "trigger" / prepared by the author for patenting in the form of independent applications for the invention. Further, when the retractable “firing unit” reaches its rear position - inside the “guide bed” / 8 /, the lever “cartridge feed” / 1 / is automatically forcibly retracted due to the interaction of the end face of the “vertical protrusion” / 4 / with its “leading” a longitudinal groove ”/ 5 / having a“ state bevel ”/ 6 /. Moreover, by the time of this abduction, the lateral “end flag” / 21 / of the said “disconnector”, also sliding along its “leading groove” / 22 /, located on the inner surface of the side wall of the “guide bed” / 8 /, manages to turn on the mechanism of the “disconnector” / 20 /, and the bolt frame / 18 /, released from the clutch with the receiver / 9 /, moves to its front position - without affecting the hammer / 16 /. In addition, the width of the aforementioned “tip” / 3 / in the horizontal projection of the bolt frame / 18 / is at least two values - the “output of the striker” of the said striker / 16 /, equipped with a return spring / 17 /.

The claimed device / limiter for the number of shots - in a “fixed” lineup / is included in the group of proposed inventions previously announced by the author - as a project of a “carriage automaton” having a permanent “intermediate” magazine, automatically charged from a removable lower “main” magazine, and “ firing unit ", moved forward - inside the" guiding bed ", for the production of a" fixed lineup "of three or four shots using a standard" intermediate "cartridge with a metal sleeve.
