Abstract

Durch die Patronenzuführvorrichtung werden die Patronen (23) seitlich neben dem Waffenrohr (11) einer Waffe zugeführt und bem Einschieben der Patronen (23) ins Waffenrohr (11) durch den Verschluss (15) müssen die Patronen (23) umgelenkt werden. Bei hoher Kadenz besteht die Gefahr, dass bei der Umlenkung die Patronen (23) mit ihrer Spitze am Waffenrohr (11) anstossenund sich dann nicht einschieben lassen. Durch die erfindungsgemässe Vorrichtung soll diese Gefahr vermieden werden. Eine schwenkbare Ablenkklinke (39) mit einer zur Waffenachse parallelen Schwenkachse (40) gestattet ein zuverlässiges Einschieben der Patrone (23) ins Waffenrohr (11)The cartridges (23) are fed to the side of the weapon barrel (11) by a weapon and the cartridges (23) must be redirected when the cartridges (23) are inserted into the weapon barrel (11) through the breech (15). If the cadence is high, there is a risk that the cartridges (23) will tip against the barrel (11) during the deflection and then cannot be inserted. This danger is to be avoided by the device according to the invention. A pivotable deflection pawl (39) with a pivot axis (40) parallel to the weapon axis allows the cartridge (23) to be reliably inserted into the weapon barrel (11).

Description

Die Erfindung betrifft eine Vorrichtung zum Einschieben einer Patrone in das Patronenlager des Waffenrohres einer selbsttätigen Feuerwaffe, mit einem hin- und hergehenden Verschluss, der die Patrone aus einem neben dem Waffenrohr angeordneten Patronenzuführerkanal in das Waffenrohr hineinschiebt und mit Führungen, welche die im Patronenzuführkanal befindliche Patrone gegen das Waffenrohr hin ablenken.The invention relates to a device for inserting a cartridge into the cartridge chamber of the weapon barrel of an automatic firearm, with a reciprocating breech which pushes the cartridge from a cartridge feed channel arranged next to the weapon barrel into the weapon barrel and with guides which guide the cartridge located in the cartridge feed channel distract against the gun barrel.

Bei einer bekannten Vorrichtung zum Zuführen von Patronengurten zu einer automatischen Feuerwaffe (siehe US-PS 2875 671), sind sogenannte Einlegehebel angeordnet, welche mit Hilfe von Stuernocken betätigt werden und welche die Patronen aus dem Patronenzuführkanal seitlich gegen das Waffenrohr verschieben, worauf die Patrone durch den .Verschluss in das Patronenlager des Waffen,rohres hineingeschoben wird.Die Steuernocken werden durch das zurücklaufende Waffenrohr betätigt.In a known device for feeding cartridge belts to an automatic firearm (see US Pat. No. 2,875,671), so-called insertion levers are arranged, which are actuated with the aid of control cams and which move the cartridges laterally out of the cartridge feed channel against the weapon barrel, whereupon the cartridge passes through the .lock is pushed into the chamber of the weapon barrel, the control cams are actuated by the returning barrel.

Diese bekannte Vorrichtung ist kompliziert und aufwendig und benötigt viele störanfällige zusätzliche Organe. Die vorliegende Erfindung bezweckt die Schaffung einer einfachen, zuverlässigen Vorrichtung, welche keine zusätzlichen Betätigungsorgane benötigt.This known device is complicated and expensive and requires many additional organs that are susceptible to faults. The present invention aims to provide a simple, reliable device which does not require additional actuators.

Die erfindungsgemässe Vorrichtung, mit der diese Aufgabe gelöst wird, ist dadurch gekennzeichnet, dass die genannten Führungen durch eine Ablenkklinke gebildet werden, die im Bereich der Patronenspitze der im Patronenzuführkanal befindlichen Patrone angeordnet ist, dass die Ablenkklinke schwenkbar gelagert ist, dass ihre Schwenkachse parallel zur Patronenachse gerichtet ist, dass die Ablenkklinke in den Patronenzuführkanal hineinragt, dass sie von der Patrone ausschwenkbar ist und eine Rücklaufsperre bildet, welche ein unbeabsichtigtes Zurückgleiten der Patronenspitze in den Patronenzuführkanal verhindert.The device according to the invention, with which this object is achieved, is characterized in that the said guides are formed by a deflection pawl which is arranged in the area of the cartridge tip of the cartridge located in the cartridge feed channel, that the deflection pawl is pivotably mounted so that its pivot axis is parallel to the Cartridge axis is directed that the deflecting pawl protrudes into the cartridge feed channel that it can be swung out of the cartridge and forms a backstop, which prevents the cartridge tip from inadvertently sliding back into the cartridge feed channel.

Ein Ausführungsbeispiel der erfindungsgemässem Vorrichtung ist anhand der beigefügten Zeichnung im folgenden ausführlich beschrieben.An embodiment of the device according to the invention is described in detail below with reference to the accompanying drawing.

Es zeigt:

  • Fig.1 einen Längsschnitt durch einen Teil einer Feuerwaffe
  • Fig.2 einen Schnitt nach Linie 11-11 in Fig.1.
It shows:
  • 1 shows a longitudinal section through part of a firearm
  • 2 shows a section along line 11-11 in Fig.1.

In Fig.l ist ein Teil des Waffengehäuses 10 einer Feuerwaffe dargestellt, an dem vorne ein Waffenrohr 11 befestigt ist. Zwei Patronenzuführkanäle 12 und 13 sind am Zapfen 14 schwenkbar am Waffengehäuse 10 befestigt. Der linke Patronenzuführkanal 12 ist ausgeschwenkt dargestellt, so dass keine Patronen aus diesem Kanal 12 der Waffe zugeführt werden können. Der rechte Patronenzuführkanal 13 befindet sich hingegen in Arbeitsstellung, so dass die Patronen 23 aus diesem Kanal 13 in das Waffenrohr 11 eingeschoben werden können. Die ausgeschwenkte Stellung des Patronenzuführkanals 13 ist mit strichpunktierten Linien angedeutet. Eine nicht dargestellte Umschaltvorrichtung sorgt dafür, dass sich immer der eine oder andere Patronenzuführkanal (12,13) in Arbeitsstellung befindet, während der andere ausgeschwenkt ist.In Fig.l a part of the gun housing 10 of a firearm is shown, to which a gun barrel 11 is attached at the front. Two cartridge feed channels 12 and 13 are pivotally attached to the barrel 14 on the weapon housing 10. The left cartridge feed channel 12 is shown pivoted out, so that no cartridges can be fed from this channel 12 to the weapon. The right cartridge feed channel 13, on the other hand, is in the working position, so that the cartridges 23 can be inserted into the gun barrel 11 from this channel 13. The pivoted-out position of the cartridge feed channel 13 is indicated by dash-dotted lines. A switching device, not shown, ensures that one or the other cartridge feed channel (12, 13) is always in the working position while the other is pivoted out.

Im Waffengehäuse 10 ist ein Verschluss 15 verschiebbar gelagert. Dieser Verschluss 15 ist in Fig.1 in seiner hintersten Stellung gezeigt, er besitzt einen Verschlusskopf 16 und ein Steuerstück 17, sowie zwei Riegel 18. Das Steuerstück 17 ist verschiebbar im Verschlusskopf 16 angeordnet. In der vordersten Stellung des Verschlusskopfes 15 ragt das Steuerstück 17 zwischen die beiden Riegel 18 hinein und drückt die Riegel 18 in Aussparungen 19 des Waffenrohres 11 hinein, so dass der Verschlusskopf 16 im Waffenrohr 11 verriegelt ist. In der hintersten Stellung des Verschlusses 15 befindet sich das Steuerstück 17 hinter den Riegeln 18 und somit ist der Verschlusskopf entriegelt. Die Verschiebung des Verschlusses 15 erfolgt in der üblichen Weise in einer Richtung durch eine nicht dargestellte Vorholfeder und in der anderen Richtung durch den Gasdruck. Auch die Förderung der Patronengurte in den Patronenzuführkanälen 12 und 13 erfolgt in der üblichen Weise. Beides ist daher hier nicht weiter beschrieben.A lock 15 is slidably mounted in the weapon housing 10. This closure 15 is shown in its rearmost position in FIG. 1, it has a closure head 16 and a control piece 17, as well as two bolts 18. The control piece 17 is displaceably arranged in the closure head 16. In the foremost position of the closure head 15, the control piece 17 projects between the two bolts 18 and presses the latches 18 into recesses 19 of the weapon barrel 11, so that the locking head 16 is locked in the weapon barrel 11. In the rearmost position of the lock 15, the control piece 17 is behind the bolts 18 and thus the lock head is unlocked. The closure 15 is displaced in the usual way in one direction by a not shown spring and in the other direction by the gas pressure. The cartridge belts are also conveyed in the cartridge feed channels 12 and 13 in the usual way. Neither is therefore described further here.

Bei der Verschiebung des Verschlusses 15 aus seiner hintersten in seine vorderste Stellung (gemäss Fig.l von rechts nach links), stösst der Verschluss 15 mit der Kante 22 gegen den Boden 36 der Patrone 23. Die Patronenachse ist gegenüber der Waffenachse geneigt. Die Patrone 23 wird an einer Ablenkvorrichtung 24 abgelenkt und in das Waffenrohr 11 hineingeschoben. Anschliessend wird die Patrone 23 durch einen Zündstift 25 des Steuerstückes 17 gezündet. Diese Ablenkvorrichtung 24, welche insbesondere in Fig.2 genauer dargestellt ist, ist Gegenstand der vorliegenden Erfindung.When the breech 15 is moved from its rearmost position to its foremost position (from right to left as shown in FIG. 1), the breech 15 abuts with the edge 22 against the bottom 36 of the cartridge 23. The cartridge axis is inclined with respect to the weapon axis. The cartridge 23 is deflected at a deflection device 24 and pushed into the weapon barrel 11. The cartridge 23 is then ignited by an ignition pin 25 of the control piece 17. This deflection device 24, which is shown in more detail in particular in FIG. 2, is the subject of the present invention.

Gemäss Fig.2 weisen die oben erwähnten Zuführkanäle 12 und 13 je eine Seitenwand 34 auf. Entlang dieser Seitenwände 34 bewegen sich die Patronen 23 in den Zuführkanälen 12,13 gegen das Waffenrohr 11 in Richtung der Pfeile A. Die beiden Ablenkvorrichtungen 24 rechts und links des Waffenrohres 11 haben die Aufgabe die Spitze der Patronen 23 gegen das Waffenrohr 11 zu lenken, wie insbesondere aus Fig.1 ersichtlich ist.According to FIG. 2, the above-mentioned feed channels 12 and 13 each have a side wall 34. The cartridges 23 move along these side walls 34 in the feed channels 12, 13 against the gun barrel 11 in the direction of the arrows A. The two deflection devices 24 on the right and left of the gun barrel 11 have the task of guiding the tip of the cartridges 23 against the gun barrel 11, as can be seen in particular from FIG.

Diese beiden Ablenkvorrichtungen 24, die spiegelbildlich ausgebildet sind, weisen je ein Gehäuse 38 auf, in dem je eine Ablenkklinke 39 schwenkbar um eine Achse 40 gelagert ist. In einer Bohrung 41 des Gehäuses 38 befindetz sich eine Hülse 42, die eine Feder 43 enthält, welche sich einerseits am Boden der Hülse 42 und andererseits am Boden der Bohrung 41 abstützt und das Bestreben hat, die Hülse 42 gegen die Ablenkklinke 39 zu drücken und dabei diese Ablenkklinke 39 in der gezeigten Stellung zu halten. Die Ablenkklinke 39 besitzt eine Schwenkfläche 44sowie eine Stützfläche 45.These two deflection devices 24, which are mirror images, each have a housing 38 in which each a deflection pawl 39 is pivotally mounted about an axis 40. In a bore 41 of the housing 38 there is a sleeve 42 which contains a spring 43 which is supported on the one hand on the bottom of the sleeve 42 and on the other hand on the bottom of the bore 41 and has the endeavor to press the sleeve 42 against the deflection pawl 39 and to keep this deflection pawl 39 in the position shown. The deflection pawl 39 has a swivel surface 44 and a support surface 45.

Die Wirkungsweise der beschriebenen Vorrichtung ist wie folgt:

  • Bei der Betätigung des nicht dargestellten Abzuges der Waffe wird der Verschluss 15 freigegebenund wird durch die Kraft der ebenfalls nicht dargestellten Vorholfeder in Fig.1 nach links bewegt, d.h. er läuft gegen das Waffenrohr 11 und stösst dabei mit der Kante 22 gegen die Patrone 23. Die Patrone 23 wird dadurch ins Waffenrohr 11 hineingeschoben und in üblicher Weise durch den Zündstift 25 gezündet.
The operation of the described device is as follows:
  • When the trigger, not shown, of the weapon is actuated, the breech 15 is released and is moved to the left in FIG. 1 by the force of the forward spring, which is also not shown, ie it runs against the barrel 11 and abuts the cartridge 23 with its edge 22. The cartridge 23 is thereby pushed into the weapon barrel 11 and ignited in the usual way by the firing pin 25.

Die Umlenkvorrichtung 24 sorgt beim Einschieben der Patrone 23 ins Waffenrohr 11, dass die Patronenspitze nirgends anstösst, sondern genau ins Patronenlager des Waffenrohres 11 hineingeschoben wird.When the cartridge 23 is inserted into the weapon barrel 11, the deflection device 24 ensures that the cartridge tip does not touch anywhere, but rather is pushed exactly into the cartridge chamber of the weapon barrel 11.

Sobald eine Patrone 23 ins Waffenrohr 11 eingeschoben wird, bewegen sich durch die nicht dargestellte Patronenzuführvorrichtung die Patronen im rechten Patronenzuführkanal 13 (Fig.2) in Richtung des Pfeiles A. Durch diese Bewegung wird die in der Nähe der Ablenkvorrichtung 24 befindliche Patrone 23 gegen die Schwenkfläche 44 der Ablenkklinke 39 gedrückt. Gegen die Kraft der Feder 43 wird die Ablenkklinke 39 im Uhrzeigersinne verschwenkt und die Patrone 23 kommt zur Anlage an die Stützfläche 45 der Ablenkklinke 39. Beim erwähnten Einschieben der Patrone 23 durch den Verschluss 15 in das Waffenrohr 11 liegt die Patrone 23 an der Stützfläche 45 an. Diese Stützfläche verhindert dabei, dass die Patrone 23 beim Einschieben ins Waffenrohr 11 in unbeabsichtigter Weise in den Zuführkanal 13 zurückgeschoben wird.As soon as a cartridge 23 is inserted into the weapon barrel 11, the cartridges in the right cartridge feed channel 13 (FIG. 2) move in the direction of the arrow A through the cartridge feed device (not shown). This movement causes the cartridge 23 located in the vicinity of the deflection device 24 to move against the Swivel surface 44 of the deflection pawl 39 pressed. Against the force of the spring 43, the deflection pawl 39 is pivoted clockwise and the cartridge 23 comes to rest against the support surface 45 of the deflection pawl 39. When the cartridge 23 is inserted through the breech 15 into the weapon barrel 11, the cartridge 23 lies on the support surface 45 at. This support surface prevents the cartridge 23 from being inadvertently pushed back into the feed channel 13 when it is inserted into the weapon barrel 11.
