Description

Die Erfindung beschäftigt sich mit einem kettengesteuerten Hüfsen-/Patronenauswurf einer Munition nach deren Verschuss bzw. bei einem Zündversager aus einer Waffe sowie einer Waffe mit einer derartigen Hülsenauswurfvorrichtung.The invention relates to a chain-controlled Hüfsen- / cartridge ejection of an ammunition after their Verschuss or in a Zündversager from a weapon and a weapon with such a sleeve ejection device.

Eine Patronenhülsenauszieheinrichtung für automatische Feuerwaffen offenbart die DE 30 38 769 C2 . Nach dem Abfeuern eines Geschosses wird während der Rückwärtsbewegung des Verschlusses die Patronenhülse durch den Verschluss aus dem Patronenlager herausgezogen. Auch die DE 10 2007 034 672 A1 beschreibt einen Verschluss und eine Ausziehkralle, die an einem Patronenbodenrand angreift, um diese aus dem Patronenlager zu entfernen.A cartridge case extraction device for automatic firearms discloses the DE 30 38 769 C2 , After firing a projectile during the backward movement of the closure, the cartridge case is pulled out of the cartridge chamber through the closure. Also the DE 10 2007 034 672 A1 describes a closure and a Ausziehclalle which engages a cartridge bottom edge to remove it from the chamber.

Aus der DE 10 2005 003 751 B3 ist eine Hülsenauffangvorrichtung für gurtgliedlose Munitionen bekannt. Darin wir vorgeschlagen, für die Rückführung der Hülsen in einen Munitionsbehälter eine Hülsenführung in Form eines Auswurfrohres einzubinden und dieses so auszurichten, dass die Hülsen in den Kettengliedern zum Liegen kommt. Dazu arbeitet das Auswurfrohr mit Fangfedern zusammen, die sich zwischen dem Auswurfrohr und einem Hülsendämpfer befinden. Bei derartigen Waffen erfolgt die Munitionszuführung nur von einer Seite der Waffe. Insbesondere wenn der Waffe die Munition von zwei Seiten zugeführt werden soll, ist eine derartige Einbindung nicht möglich. Trotzdem kann es erwünscht sein, einen zielgerichteten Auswurf der Hülsen zu erreichen.From the DE 10 2005 003 751 B3 is a sleeve catcher for batorless ammunition known. In it we proposed to incorporate a sleeve guide in the form of an ejection tube for the return of the sleeves in an ammunition container and to align this so that the sleeves comes to rest in the chain links. For this purpose, the ejection tube cooperates with spring springs, which are located between the ejection tube and a sleeve damper. In such weapons, the ammunition supply takes place only from one side of the weapon. In particular, when the weapon ammunition to be supplied from two sides, such integration is not possible. Nevertheless, it may be desirable to achieve a targeted ejection of the sleeves.

Der Erfindung stellt sich die Aufgabe, eine einfache Hülsenauswurfvorrichtung aufzuzeigen, die baulich klein gehalten, das Ausstoßen der Hülse bzw. eines Zündversagers auch bei einer beiderseitigen Munitionszuführung ermöglicht.The invention has as its object to show a simple sleeve ejection device, the structurally small, the ejection of the sleeve or a Zündversagers also allows for mutual ammunition feed.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1 bzw. 8. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgezeigt.The object is achieved by the features of claim 1 and 8. Advantageous embodiments are shown in the subclaims.

Der Erfindung liegt die Idee zugrunde, das Ausstoßen bzw. das Ausleiten der Hülse durch ein Auswurfrohr zu unterstützen. Dieses ist jedoch bevorzugt in Schussrichtung vor einem zur Waffe gehörenden Rotor eingebunden. Für eine baukleine Variante ist das Auswurfrohr bevorzugt oberhalb des Waffenrohres angeordnet. Die Wülsenauswurfvorrichtung wird ergänzt durch zumindest eine (umlaufende, geschlossene) Kette und einen durch die Kette getriebenen Auswerfer. Dabei schiebt der mit der Kette funktional verbundene Auswerfer die Hülse in das Hülsen-Ausstoß- bzw. Auswurfrohr. Durch die Kette wird genügend Geschwindigkeit erzeugt, damit die Hülse durch das Auswurfrohr getrieben werden kann. Die Kette ist ihrerseits horizontal (auch parallel möglich) zum Rotor ausgerichtet. In einer weiteren Ausgestaltung kann das Ausstoßen durch das Ausstoßrohr durch einen Hülsenbeschleuniger unterstützt werden. Durch diesen Beschleuniger wird auf den Hülsenboden ein kurzer Impuls eingeleitet, der das Ausstoßen beschleunigt und sicherstellt.The invention is based on the idea to support the ejection or the discharge of the sleeve by an ejector tube. However, this is preferably integrated in the weft direction in front of a weapon belonging to the rotor. For a small construction variant, the ejection tube is preferably arranged above the weapon barrel. The Wülsenauswurfvorrichtung is supplemented by at least one (circulating, closed) chain and driven by the chain ejector. In this case, the ejector functionally connected to the chain pushes the sleeve into the sleeve ejection or ejection tube. The chain provides enough speed to allow the sleeve to be driven through the ejector tube. The chain is in turn aligned horizontally (also possible in parallel) to the rotor. In a further embodiment, the ejection can be supported by the ejection tube by a sleeve accelerator. Through this accelerator, a short pulse is introduced to the bottom of the case, which accelerates the ejection and ensures.

Grundsätzlich ist der Einsatz einer derartigen Auswurfvorrichtung an einer Waffe vorgesehen, bei welcher die Munition durch einen Verschluss in eine Patronenkammer des Waffenrohres bei seiner Vorwärtsbewegung hinein geschoben wird, die in einem Rotor bzw. Stern liegt. Derartige Waffensysteme sind beispielsweise aus der DE 10 2005 045 824 B3 bekannt, auf die hiermit Bezug genommen wird. Die Hülse wird ihrerseits nach erfolgtem Schuss durch beispielsweise eine Kralle am Verschluss aus einem Patronenlager wieder herausgezogen und in dem Rotor an einer anderen Stelle abgelegt. An diese abgelegte Hülse greift nun erfindungsgemäß der Auswerfer an, der seinerseits durch die Kette nach vorne geführt wird. Dadurch wird ein einfacher Transport der Hülse erreicht, da der Auswerfer selbst in keine Nut oder dergleichen eingreifen muss, sondern an den Hülsenboden von hinten angreifen kann.Basically, the use of such ejection device is provided on a weapon, in which the ammunition is pushed through a closure in a cartridge chamber of the weapon barrel in its forward movement, which is located in a rotor or star. Such weapons systems are for example from the DE 10 2005 045 824 B3 known, to which reference is hereby made. The sleeve is in turn withdrawn after a successful shot by, for example, a claw on the closure of a chamber and again stored in the rotor at a different location. According to the invention, the ejector engages with this deposited sleeve, which in turn is guided forwards by the chain. As a result, a simple transport of the sleeve is achieved because the ejector itself does not have to engage in any groove or the like, but can attack the sleeve bottom from behind.

Um zu verhindern, dass die durch das Auswurfrohr ausgeworfene Hülse gegen das Waffenrohr getrieben wird, ist das Auswurfrohr in einem Winkel zur Rohrseelenachse angebracht. In einer bevorzugten Ausführung ist das Auswurfrohr in Schussrichtung leicht nach oben gerichtet eingebunden.In order to prevent the ejected through the ejector tube sleeve is driven against the gun barrel, the ejector tube is mounted at an angle to the tube axis. In a preferred embodiment, the ejection tube is slightly directed upwards in the direction of firing.

Um zudem ein einfaches Anschnäbeln der Hülse beim Einführen bzw. Zuführen der Hülse in das Auswurfrohr zu schaffen, weist das Auswurfrohr eine angepasste geometrische Form auf. Im Einlaufbereich des Auswurfrohres, dessen Durchmesser auf den Durchmesser der Hülse abgestimmt ist, weist dieser Bereich eine gegenüber dem Durchmesser des Auswurfrohres größere Umrandung auf, die sich dann leicht verjüngt. Durch eine beispielsweise V-förmige Aussparung im Einlaufbereich des Auswurfrohres wird Platz für den Hülsenbeschleuniger geschaffen. Dieser kann eine einfache Stufen- bzw. Treppenform aufweisen. Der Hülsenbeschleuniger ist mit einer Einheit verbunden, die den auf den Hülsenboden einzuleitenden Impuls erzeugt, wenn der Hülsenboden der auszuwerfenden Hülse im Auswurfrohr hineingeführt worden ist.In addition, in order to create a simple beaking of the sleeve during insertion or feeding of the sleeve into the ejection tube, the ejection tube has an adapted geometric shape. In the inlet region of the ejection tube, whose diameter is matched to the diameter of the sleeve, this region has a larger compared to the diameter of the ejection tube border, which then tapers slightly. An example of a V-shaped recess in the inlet region of the ejection tube space is created for the sleeve accelerator. This can have a simple step or staircase shape. The sleeve accelerator is connected to a unit which generates the pulse to be introduced on the sleeve bottom when the sleeve bottom of the sleeve to be ejected has been guided into the ejection tube.

In Weiterführung der Erfindung sind zwei Auswurfrohre vorgesehen, so dass der Waffe die Munition von beiden Seiten zugeführt werden kann. In diesem Fall sind dann auch zwei mittels Ketten angetriebene Auswerfer eingebunden. Wie in der Einzelausführung befinden sich die Auswurfrohre bevorzugt oberhalb des Waffenrohres und sind in einem leichten Winkel von der Rohrseelenachse des Waffenrohres abgeschwenkt nach oben gerichtet angebracht. Das besondere an dieser Ausführung ist, dass die Ketten und die Auswerfer ihrerseits unabhängig der Munitionszuführung, d.h., unabhängig davon, von welcher Seite die Munition der Waffe zugeführt wird, arbeiten können. Das ermöglicht ein einfaches Umschalten der Munitionszuführung während des Betriebes der Waffe ohne weitere Anpassungen.In continuation of the invention, two ejector tubes are provided, so that the weapon can be supplied to the ammunition from both sides. In this case, then two driven by chains ejector are involved. As in the single version, the ejector tubes are preferably above the gun barrel and are mounted at a slight angle from the tube bore axis of the gun barrel directed upward directed. The particularity of this design is that the chains and ejectors, in turn, can operate independently of the ammunition feed, i.e., regardless of which side the ammunition is being supplied to the weapon. This allows easy switching of the ammunition feed during operation of the weapon without further adjustments.

Das / die Auswurfrohr(e) kann / können auch hinter dem Rotor eingebunden werden, wobei die Kette etc. entsprechend anzuordnen sind. Eine spiegelbildliche Anordnung der Hülsenauswurfvorrichtung(en) ermöglicht auch deren Einbindung unterhalb der Waffe.The ejection tube (s) can / can also be integrated behind the rotor, the chain, etc. are to be arranged accordingly. A mirror-image arrangement of the sleeve ejection device (s) also allows their integration below the weapon.

Es versteht sich, dass durch diese Auswurfvorrichtung(en) auch mögliche Zündversager aus dem Waffensystem herausgeführt werden können.It is understood that by this ejector (s) also possible Zündversager can be led out of the weapon system.

Die Erfindung soll anhand eines Ausführungsbeispieles mit einer beidseitigen Zuführung der Munition mit Zeichnung näher erläutert werden. Es zeigt:

Fig. 1 bis 3 zeigen einen Ausschnitt einer Waffe 1, bei der eine Munition 2 (Fig. 3) durch einen Verschluss 3 in ein nicht näher dargestelltes Waffenrohr verbracht wird. Im vorliegenden Ausführungsbeispiel ist ein Rotor 4 mit drei Schalen 5-7 für die Ausnahme der dem Waffenrohr zuzuführenden Munition 2, dem Vorlegen vor dem Verschluss 3 und dem Abtransport einer Hülse 8 bzw. eines Zündversagers ausgebildet. Der Rotor 4 kann in beide Richtungen gedreht werden. Vor den beiden oberen Schalen rechts und links (5, 7) ist je ein Auswurfrohr 9, 10 angeordnet. Diese sind leicht nach oben und in einem Winkel vom Waffenrohr weg gerichtet. Oberhalb der Schalen 5, 7 ist eine zur Auswurfvorrichtung 30 zugehörige Konstruktion 11 angebracht. Diese umfasst zwei bevorzugt motorisch angetriebene Ketten 12, 13. Mit den Ketten 12, 13 steht je ein Auswerfer 14, 15 funktional in Verbindung. Die Auswerfer 14, 15 werden in je einem Gehäuse oder Rahmen 16, 17 gehalten. Die Rahmen 16, 17 besitzen jeweils eine Nut 18, 19 und sind ihrerseits waffenfest in einer Führung geführt (nicht näher dargestellt). Die Ketten 12, 13 laufen zeitgleich und schussabhängig (abhängig der Schusszyklen). Dabei können die Ketten 12, 13 gleich- oder zueinander gegenläufig getrieben werden. Beide Auswerfer 14 sind bei ihrem Vorlauf jeweils ausgefahren und beim jeweiligen Rücklauf hochgezogen. Läuft die Kette 12 mit nach unten ausgefahrenen Auswerfer 14 nach vorne, ist der nach oben gezogene Auswerfer 15 auf dem Weg nach hinten und umgekehrt. Für das Ausfahren oder Hochfahren der Auswerfer 14, 15 verfügt die Auswurfvorrichtung 30 über jeweils einen in den bewegbaren Rahmen 16, 17 eingebundene Nut 18, 19. Andere konstruktive Varianten sind ebenfalls denkbar. Fig. 1 to 3 show a section of a weapon 1, in which an ammunition 2 ( Fig. 3 ) is spent by a shutter 3 in a gun not shown in detail. In the present embodiment, a rotor 4 is formed with three shells 5-7 for the exception of the gun barrel supplied ammunition 2, the presentation before the shutter 3 and the removal of a sleeve 8 and a Zündversagers. The rotor 4 can be rotated in both directions. Before the two upper shells on the right and left (5, 7) is ever an ejector 9, 10 are arranged. These are directed slightly upwards and at an angle away from the gun barrel. Above the shells 5, 7 a to the ejector 30 associated construction 11 is attached. This includes two preferably motor-driven chains 12, 13. With the chains 12, 13 is each an ejector 14, 15 functionally connected. The ejector 14, 15 are each held in a housing or frame 16, 17. The frames 16, 17 each have a groove 18, 19 and are in turn guided arm-fixed in a guide (not shown in detail). The chains 12, 13 run simultaneously and shot-dependent (depending on the shot cycles). In this case, the chains 12, 13 are driven in the same direction or in opposite directions. Both ejectors 14 are each extended at their forward and pulled up the respective return. Runs the chain 12 with downwardly extended ejector 14 forward, the pull-up ejector 15 is on the way to the rear and vice versa. For the extension or raising of the ejectors 14, 15, the ejector 30 has in each case one in the movable frame 16, 17 integrated groove 18, 19. Other structural variants are also conceivable.

Für das sichere Gleiten der Hülse 8 in das jeweilige Auswurfrohr 9, 10 weisen diese eine spezielle Bauform auf. Die Öffnung bzw. die Einführöffnung 20 der Auswurfrohre 9, 10 ist im Durchmesser größer als das Kaliber der Hülse 8 gewählt. Zudem weisen die Auswurfrohre 9, 10 im Einfädelbereich eine V-förmige Ausnehmung 21 auf. In diese ragt jeweils ein Hülsenbeschleuniger 22. Dieser unterstützt das Ausstoßen der Hülse 8 aus dem Auswurfrohr 9, 10.For the safe sliding of the sleeve 8 in the respective ejector tube 9, 10, these have a special design. The opening or the insertion opening 20 of the ejector tubes 9, 10 is larger in diameter than the caliber of the sleeve 8 is selected. In addition, the ejector tubes 9, 10 in the threading a V-shaped recess 21. In each of these projects a sleeve accelerator 22. This supports the ejection of the sleeve 8 from the ejection tube 9, 10th

Die Funktionsweise ist wie folgt:The operation is as follows:

Der Rotor 4 umfasst drei Schalen, hier mit 5, 6, 7 bezeichnet, und wird entsprechend des Schussablaufes (Schusszyklen - siehe beispielsweise DE 10 2008 060 217 A1 ) gedreht. Das Drehen kann in beide Richtungen - nach rechts oder nach links - erfolgen. Betrachtet wird nunmehr die Zuführung und Abführung der Munition 2 von links gesehen in Schussrichtung S und damit das Drehen des Rotors 4 nach links, entgegengesetzt dem Uhrzeigersinn (Fig. 3).The rotor 4 comprises three shells, here denoted by 5, 6, 7, and is corresponding to the shot sequence (shot cycles - see, for example DE 10 2008 060 217 A1 ) turned. The rotation can be done in both directions - to the right or to the left. Consider now the supply and discharge of the ammunition 2 seen from the left in the weft direction S and thus the rotation of the rotor 4 to the left, in the counterclockwise direction ( Fig. 3 ).

Die Schale 5 des Rotors 4, in Schussrichtung gesehen links, dient zur Aufnahme einer neuen Munition 2. In der Schale 6, untere Schale des Rotors 4, befindet sich die aktuell zu verschießende Munition 2. In der rechts im Rotor 4 befindlichen Schale 7 liegt die Hülse 8 der zuvor verschossenen Munition.The shell 5 of the rotor 4, seen in the weft direction left, is used to hold a new ammunition 2. In the shell 6, lower shell of the rotor 4, there is currently ammunition to be fired 2. In the right in the rotor 4 located shell 7 is located the sleeve 8 of the previously lost ammunition.

Der Verschluss 3 nimmt beim nach Vorne fahren die in der Schale 6 befindliche Munition 2 mit in die Patronenkammer (nicht näher dargestellt). Das Waffenrohr wird verriegelt, der Schuss erfolgt. Danach wird der Verschluss 3 wieder nach hinten verfahren. Dabei transportiert der Verschluss 3 die Hülse 8 der verschossenen Munition 2 in die Schale 6 zurück und legt sie dort ab. Beim weiteren Rückwärtsfahren des Verschlusses 3 wird nunmehr der Rotor 4 gedreht, so dass die Schale 6 mit der Hülse 8 in die Position der Schale 7, die Schale 7 in die vorherige Position der Schale 5 und die Schale 5 in die vorherige Position der Schale 6 verdreht werden. Es liegt nunmehr wieder eine neue Munition 2 in der unteren Schale des Rotors 4 vor dem Verschluss 3 und die Hülse 8 auf der der Munitionseinlegeposition gegenüberliegenden Schale.The shutter 3 takes when driving forward the ammunition 2 located in the shell 6 with in the cartridge chamber (not shown in detail). The gun barrel is locked, the shot is made. Thereafter, the shutter 3 is moved back to the back. The shutter 3 transports the sleeve 8 of the ammunition 2 shot back into the shell 6 and deposits it there. Upon further reversing the shutter 3, the rotor 4 is now rotated, so that the shell 6 with the sleeve 8 in the position of the shell 7, the shell 7 in the previous position of the shell 5 and the shell 5 in the previous position of the shell. 6 to be twisted. It is now again a new ammunition 2 in the lower shell of the rotor 4 in front of the closure 3 and the sleeve 8 on the opposite of the ammunition insertion position shell.

In der Zeit, in der eine neue Munition 2 in die linke Schale (5) eingelegt wird, fährt der links angeordnete Auswerfer 14, der in seiner Nut 18 nach oben gezogen ist, nach hinten. Dadurch wird ein Kollidieren mit der eingelegten Munition 2 vermieden. Parallel dazu geht der sich hinten befindliche und in der Nut 19 nach unten ausgefahrene rechte Auswerfer 15 nach vorne und nimmt die Hülse 8 mit aus der Schale 7 in Richtung Auswurfrohr 10. Die Hülse 8 wird durch das Auswurfrohr 10 ausgestoßen.In the time in which a new ammunition 2 in the left shell (5) is inserted, moves the left ejector 14, which is pulled in its groove 18 upwards, to the rear. This avoids colliding with the inserted ammunition 2. Parallel to this, the rear ejector 15 located at the rear and extending downwards in the groove 19 goes forward and takes the sleeve 8 out of the shell 7 in the direction of the ejection tube 10. The sleeve 8 is ejected through the ejection tube 10.

Wie bereits erwähnt, kann das Ausstoßen der Hülse 8 durch einen Hülsenbeschleuniger 22 verbessert werden (Fig. 4). Dabei erhält der Hülsenbeschleuniger 22 einen Impuls, durch den der Hülsenbeschleuniger 22 aus seiner Ruhe-Position in Richtung Hülsenboden getrieben wird, beispielsweise über eine Feder. Die federgetriebene Einrichtung 23 erhält ihrerseits die Information beispielsweise von dem Nocken 24, über den die Auswerfer 14, 15 mit der Kette 12, 13 funktional verbunden sind (hier nicht näher dargestellt). Der Nocken 24 wirkt dann so auf die Einrichtung 23 ein, dass diese den Hülsenbeschleuniger 22 bewegt, hier in Schussrichtung S.
Die Munitionszuführung von rechts und der Hülsenauswurf laufen ähnlich ab, wobei der Rotor 4 in die andere Richtung gedreht wird. Dabei wird die in der linken Schale (5) liegende Hülse 8 durch das Auswurfrohr 9 aus dem Waffensystem verbracht. Die Ketten 12, 13 arbeiten wie beschrieben.As already mentioned, the ejection of the sleeve 8 by a sleeve accelerator 22 can be improved ( Fig. 4 ). In this case, the sleeve accelerator 22 receives a pulse, by which the sleeve accelerator 22 is driven from its rest position in the direction of the sleeve bottom, for example via a spring. The spring-driven device 23 in turn receives the information, for example, from the cam 24, via which the ejector 14, 15 with the chain 12, 13 are functionally connected (not shown here). The cam 24 then acts on the device 23 in such a way that it moves the sleeve accelerator 22, here in the weft direction S.
The ammunition supply from the right and the tube ejection run similarly, with the rotor 4 being rotated in the other direction. In this case, the sleeve 8 located in the left shell (5) is brought out of the weapon system through the ejection tube 9. The chains 12, 13 work as described.
