Description

Anordning ved maskingevær Machine gun device

Oppfinnelsen angår en anordning ved maskingevær, særlig et tyngre maskingevær, fortrinnsvis med kaliber 12,7 mm, spesielt også på et pansret og bevæpnet kjøretøy, som omfatter vanlige deler, så som drivmotor, drivverk, hjul- eller beltedrev, et besetningsrom og et hus, som tar opp installasjoner og påbygg, samt en våpeninstallasjon. The invention relates to a device for a machine gun, in particular a heavier machine gun, preferably with a caliber of 12.7 mm, especially also on an armored and armed vehicle, which includes common parts, such as a drive motor, drive mechanism, wheel or belt drive, a crew compartment and a housing , which covers installations and superstructures, as well as a weapons installation.

Bakgrunn Background

Ved bevæpning er sikkerheten ved avfyring en grunnleggende viktig funksjon. Ved feil i sikkerhetskretsene eller i de tilhørende delene, må en ufrivillig utløsing av et skudd unngås, så langt det overhodet lar seg gjøre. Dette gjelder for alle typer bevæpning med automatvåpen. When it comes to weaponry, the safety of firing is a fundamentally important function. In the event of a fault in the safety circuits or in the associated parts, an involuntary firing of a shot must be avoided as far as possible. This applies to all types of armament with automatic weapons.

De fleste automatvåpen har en innretning som gjør det mulig at våpenlåsen blir sperret i den bakre endeposisjonen etter et enkeltskudd eller en skuddserie. Dette gir en dobbelt sikkerhet, ettersom slagstiften sperres i låsen, og låsen selv holdes i den bakre stillingen. Most automatic weapons have a device that makes it possible for the weapon lock to be locked in the rear end position after a single shot or a series of shots. This provides double security, as the firing pin is locked in the lock, and the lock itself is held in the rear position.

Noen våpen, som for eksempel det tunge maskingeværet 12,7 mm, har ingen sikkerhetsinnretning som muliggjør en bakre sperring av låsen mot skuddretningen. Her blir en patron ført inn i patronkammeret etter hver avfyringsstans, og bare slagstiften blir sperret. Some weapons, such as the 12.7 mm heavy machine gun, do not have a safety device that enables a rear blocking of the lock against the direction of fire. Here, a cartridge is fed into the cartridge chamber after each firing stop, and only the firing pin is blocked.

Ulempen med en slik utførelse består først og fremst i at det ved en feil i området til slagstift-sperringen, kan skje en ufrivillig skuddutløsning, en katastrofal feil som ofte gir store følger. Ved en slik våpenutførelse kan det dessuten bare manuelt omkobles mellom enkeltskudd og skuddserier. The disadvantage of such a design consists primarily in the fact that in the event of a fault in the area of the firing pin lock, an involuntary shot can occur, a catastrophic fault that often has major consequences. With such a weapon design, it can also only be manually switched between single shots and series of shots.

Formål Purpose

Formålet med oppfinnelsen er å gjøre våpen, så som det tunge maskingeværet 12,7 mm, sikrere mot ufrivillig utløsning av skudd. Eksisterende utstyr og teknikk blir ikke erstattet, derimot utrustet til dobbel sikkerhet. The purpose of the invention is to make weapons, such as the 12.7 mm heavy machine gun, safer against involuntary firing of shots. Existing equipment and technology will not be replaced, but equipped for double safety.

Oppfinnelsen The invention

Dette formålet oppnås i samsvar med oppfinnelsen, slik som angitt i den karakteriserende delen av patentkrav 1. Ytterligere trekk fremgår av de uselvstendige This purpose is achieved in accordance with the invention, as stated in the characterizing part of patent claim 1. Further features appear from the independent

patentkravene. the patent requirements.

Med anordningen i samsvar med oppfinnelsen er det mulig å gjøre våpenet slik, at våpenlåsen, både etter et enkeltskudd så vel som etter avslutning av en skuddserie, sperres på en slik måte at både slagstiften og hele låsen holdes fast i en definert bakre og sikret posisjon. Dessuten er det mulig å bruke våpenet under panserbeskyttelse, for eksempel fjernstyrt fra det indre rommet til et kjøretøy, valgfritt med enkeltskudd eller skuddserier, uten å måtte foreta denne omkoblingen på våpenet for hånd. With the device in accordance with the invention, it is possible to make the weapon such that the weapon lock, both after a single shot as well as after the end of a series of shots, is blocked in such a way that both the firing pin and the entire lock are held firmly in a defined rear and secured position . In addition, it is possible to use the weapon under armor protection, for example remotely controlled from the interior of a vehicle, optionally with single shots or series of shots, without having to make this switch on the weapon by hand.

Fordelene med oppfinnelsen omfatter at et våpen av den beskrevne typen oppnår et ekstra sikkerhetsnivå, og således kan brukes på en dreibar lavett, noe som av sikkerhetsgrunner ofte ellers ikke tillates. Videre kan det avfyres i enkeltmodus, noe som er en forutsetning for visse brukstilfeller og som kan føre til sparing av ammunisjon. The advantages of the invention include that a weapon of the type described achieves an extra level of safety, and can thus be used on a rotatable weapon, which for safety reasons is often otherwise not permitted. Furthermore, it can be fired in single mode, which is a prerequisite for certain use cases and which can lead to a saving of ammunition.

Eksempel Example

I det følgende beskrives et utførelseseksempel av oppfinnelsen, som er skjematisk fremstilt i tegningen, der Figur 1 viser et blokkskjema for en sikrings- og enkeltavfyringsanordning for tyngre maskingevær. Figur 1 viser et automatvåpen 1 med ei våpenpipe 2, en avfyringsskyver 3, som sitter på siden av våpenet og som blir beveget, og en lås 5, foran hvilke det ligger en patron 4. Alle detaljer som er uvesentlige i denne sammenhengen er utelatt. I låsen er det antydet en slagstift 6. Et manipulatorelement 8, som drives med en ekstern kraft, kan sperre eller frigjøre låsen 5 i den antydete bakre stillingen, ved hjelp av en armutveksling. En posisjonssensor 7 overvåker posisjonen til låsen 5. Et andre manipulatorelement 11 kan frigjøre eller holde fast og sikre avfyringsskyveren 3, ved hjelp av en arm 12. Ved hjelp av en håndbetjening 9 og nødavfyring, kan våpenet 1 avfyres uten ekstern kraft. Til dette manøvreres manipulatorarmene 8 og 11 med håndbetjeningen 9, ved hjelp av en betjeningswire 10. Meldings- og betjeningselementer for posisjonsovervåkningen til tilbakeholdings-anordningen 14, varsel 15, avfyringsknapp 16, omkobling enkelskudd/skuddserie 17, ytterligere sikkerhetskretser i et kjøretøy 18 og sensorsignal 19 fra låsen, blir styrt med en styring 13, og kan utløse befalingssignalene avfyring 20 og låsfrigjøring 21. In the following, an embodiment of the invention is described, which is shown schematically in the drawing, where Figure 1 shows a block diagram for a safety and single firing device for heavier machine guns. Figure 1 shows an automatic weapon 1 with a barrel 2, a firing slide 3, which sits on the side of the weapon and is moved, and a lock 5, in front of which is a cartridge 4. All details that are unimportant in this context have been omitted. A striker 6 is indicated in the lock. A manipulator element 8, which is operated with an external force, can block or release the lock 5 in the indicated rear position, by means of an arm exchange. A position sensor 7 monitors the position of the lock 5. A second manipulator element 11 can release or hold and secure the firing pusher 3, by means of an arm 12. By means of a hand control 9 and emergency firing, the weapon 1 can be fired without external force. For this, the manipulator arms 8 and 11 are maneuvered with the hand control 9, using an operating wire 10. Message and operating elements for the position monitoring of the restraining device 14, warning 15, firing button 16, switching single shot/shot series 17, additional safety circuits in a vehicle 18 and sensor signal 19 from the lock, is controlled with a control 13, and can trigger the command signals firing 20 and lock release 21.

I tillegg til eksisterende avfyrings-elektromagnet 11 som manipulator, blir en ytterligere manipulator 8 som drives med ekstern kraft, for eksempel en ytterligere elektromagnet, anbrakt i området til den manuelle avfyringsanordningen ved bakre ende av våpenet 1 eller på et annet egnet sted, for økning av sikkerheten. En, for eksempel elektronisk, styring 13 mottar fjernstyrings- og sensorsignalene 14, 16,17,18,19 som innganger, og styrer utgangene 20, 21, som er koblet til manipulatorene 8, 11, samt varsellampen 15 ved feiltilfeller. For ytterligere økning av sikkerheten, blir posisjonen til låsen permanent overvåket ved hjelp av sensoren 7. In addition to the existing firing electromagnet 11 as a manipulator, an additional manipulator 8 driven by external force, for example an additional electromagnet, is placed in the area of the manual firing device at the rear end of the weapon 1 or in another suitable place, to increase of the security. An, for example electronic, control 13 receives the remote control and sensor signals 14, 16, 17, 18, 19 as inputs, and controls the outputs 20, 21, which are connected to the manipulators 8, 11, as well as the warning lamp 15 in case of errors. To further increase security, the position of the lock is permanently monitored using the sensor 7.

Ved utløsning av et enkeltskudd, frigir styringen 13 låsen 5 ved hjelp av manipulatoren 8, til posisjonssensoren 7 ser at låsen har forlatt den bakre holdeposisjonen. Deretter kobler styringen 13 ut manipulatoren 8, og først når posisjonsovervåkningen til tilbakeholdings-anordningen 14 er slik at låsen igjen kan holdes tilbake, blir avfyringsmanipulatoren 11 styrt av styringen 13. Slik blir det sikret, at et enkeltskudd kan utløses, og at låsen alltid blir sikkert sperret i den bakre holdeposisjonen etter et enkeltskudd. Så snart låsen 5 beveger seg forover i retning mot våpenpipa 2, blir enkeltskuddmanipulatoren 8 igjen deaktivert, og etter avfyring av et skudd blir låsen sikkert grepet og fastholdt etter retur til den bakre posisjonen. When a single shot is fired, the control 13 releases the lock 5 by means of the manipulator 8, until the position sensor 7 sees that the lock has left the rear holding position. The control 13 then disconnects the manipulator 8, and only when the position monitoring of the restraining device 14 is such that the lock can again be held back, the firing manipulator 11 is controlled by the control 13. This ensures that a single shot can be fired, and that the lock is always securely locked in the rear holding position after a single shot. As soon as the lock 5 moves forward in the direction of the gun barrel 2, the single shot manipulator 8 is deactivated again, and after firing a shot the lock is securely gripped and held after returning to the rear position.

Ved utløsning av en skuddserie blir begge manipulatorene 8,11 samtidig og vedvarende styrt av styringen 13. Ved slutten av skuddserien blir avfyringsmagneten, henholdsvis manipulatoren 11, først deaktivert når posisjonsovervåkningen til tilbakeholdings-anordningen 14 for låsen signaliserer at låsen 5 kan gripes, og når posisjonssensoren 7 i tillegg ser at låsen har nådd den bakre holdeposisjonen. Således blir det sikret at låsen etter en skuddserie (vedvarende avfyring) alltid blir sikkert sperret i den bakre gripeposisjonen, og dermed blir den dobbelte sikringen fremskaffet. When a series of shots is triggered, both manipulators 8,11 are simultaneously and continuously controlled by the control 13. At the end of the series of shots, the firing magnet, respectively the manipulator 11, is only deactivated when the position monitoring of the retention device 14 for the lock signals that the lock 5 can be grasped, and when the position sensor 7 also sees that the lock has reached the rear holding position. Thus it is ensured that after a series of shots (sustained firing) the lock is always securely locked in the rear grip position, and thus the double safety is provided.
