Description

Die Erfindung betrifft einen Gewehrlauf mit integrierter Patronenführung. Die Erfindung betrifft außerdem ein Repetiergewehr mit einem derartigen Gewehrlauf.The invention relates to a gun barrel with an integrated cartridge guide. The invention also relates to a repeating rifle with such a gun barrel.

Eine störungsfreie Patronenzufuhr in das Patronenlager eines Laufs stellt bei Handfeuerwaffen eine für die ordnungsgemäße Funktion wichtige Voraussetzung dar. Es muss insbesondere sichergestellt werden, dass es beim Laden der Handfeuerwaffe zu keiner durch die Patronen bedingten Ladehemmung oder Fehlfunktion kommt und auch unterschiedliche Munitionstypen ohne Störungen in das Patronenlager gelangen. Um derartige Störungen zu vermeiden, sind bereits Waffen bekannt, in deren Lauf spezielle Patronenzuführungen die Unterstützung der Patronenzufuhr zum Patronenlager vorgesehen sind.A trouble-free cartridge feed into the chamber of a barrel is an important prerequisite for proper functioning of handguns. In particular, it must be ensured that when loading the handgun there is no jam or malfunction caused by the cartridges and that different types of ammunition without interference in the Cartridge chamber arrive. In order to avoid such disturbances, weapons are already known, in the course of which special cartridge feeds are provided to support the cartridge feed to the cartridge chamber.

Aus der britischen Patentanmeldung GB 555 265 A ist eine Zuführvorrichtung bekannt, die das Zuführen einer Patrone in das Patronenlager einer automatischen Waffe unterstützt. Die Zuführvorrichtung umfasst dabei einen schwenkbaren, gefederten Zuführhebel der nahe dem Patronenlager der Waffe angeordnet ist. Über den Verschlussblock wird die Patrone dabei in die Richtung des Patronenlagers befördert, wobei die Nase der Patrone zunächst gegen das freie Ende des Zuführhebels drückt. Der schwenkbare Zuführhebel, der die Patrone in das Patronenlager leitet, wird dabei mit zunehmendem Vorschub der Patrone in eine zur Aufnahme des Zuführhebels vorgesehene Aussparung gedrückt. Die für den Zuführhebel vorgesehene Aussparung ist jedoch anfällig für Verschmutzungen, wodurch die Funktionsweise des Zuführhebels und somit ein sicheres Zuführen der Patrone beeinträchtigt werden kann. Außerdem ist die Herstellung sowie ein Austauschen oder Reinigen der Zuführvorrichtung relativ aufwändig.From the British patent application GB 555 265 A a feeding device is known which assists in feeding a cartridge into the chamber of an automatic weapon. The feed device comprises a pivotable, spring-loaded feed lever which is arranged near the cartridge chamber of the weapon. The cartridge is conveyed in the direction of the cartridge chamber via the breech block, the nose of the cartridge initially pressing against the free end of the feed lever. The pivotable feed lever, which guides the cartridge into the cartridge chamber, is pressed into a recess provided for receiving the feed lever as the cartridge advances. The recess provided for the feed lever is, however, susceptible to contamination, which can impair the functioning of the feed lever and thus the safe feeding of the cartridge. In addition, the manufacture and replacement or cleaning of the feed device is relatively complex.

In der FR 416 674 ist ein Waffenlauf mit einer Patronenführung offenbart. Die Patronenführung besteht aus zwei in Form halber Hülsen ausgebildeter Teile, von denen die obere Halbhülse in dem Gewehrlauf und die untere Halbhülse an dem axialbeweglichen Verschluss angeordnet sind. Die im Gewehrlauf befestigte Halbhülse ist fest im Lauf angeordnet und die untere Halbhülse ist in einem zur Laufbohrung koaxialen erweiterten hinteren Teil des Laufs verschiebbar.In the FR 416 674 a gun barrel with a cartridge guide is disclosed. The cartridge guide consists of two parts designed in the form of half sleeves, of which the upper half sleeve is arranged in the gun barrel and the lower half sleeve is arranged on the axially movable bolt. The half-sleeve fastened in the rifle barrel is fixed in the barrel and the lower half-sleeve is displaceable in an enlarged rear part of the barrel that is coaxial with the barrel bore.

In der US 4 259 892 A sind mehrteilige Patronenhalter zum Einsatz in einem Gewehrlauf offenbart. Der Patronenhalter besteht aus drei zangenförmigen Segmenten und wird durch federbelastete Stifte in eine hintere Position gedrückt.In the U.S. 4,259,892 A multi-part cartridge holders for use in a gun barrel are disclosed. The cartridge holder consists of three pincer-shaped segments and is pushed into a rear position by spring-loaded pins.

Aufgabe der Erfindung ist es, einen Gewehrlauf und ein Repetiergewehr mit einem solchen Gewehrlauf zu schaffen, die eine verbesserte Patronenzuführung ermöglichen.The object of the invention is to create a rifle barrel and a repeating rifle with such a rifle barrel which enable improved cartridge feed.

Diese Aufgabe wird durch einen Gewehrlauf mit den Merkmalen des Anspruchs 1 und durch ein Repetiergewehr mit den Merkmalen des Anspruchs 12 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a gun barrel with the features of claim 1 and by a repeating rifle with the features of claim 12. Appropriate refinements and advantageous developments of the invention are specified in the subclaims.

Bei dem erfindungsgemäßen Gewehrlauf ist das mindestens eine Führungselement in einer parallel zur Laufbohrung verlaufenden Führungsaufnahme im Gewehrlauf verschiebbar geführt. Das Führungselement kann so zwischen einer ausgefahrenen Führungsstellung und einer eingeschobenen Feuerstellung verschoben werden. Über das Führungselement wird die Bewegung der Patrone beim Einführen in das Patronenlager begrenzt und die Patrone geführt. In der Feuerstellung ist das Führungselement in den Lauf eingeschoben und dort gut geschützt. Das Führungselement ist stiftförmig und die zugehörige Führungsaufnahme als Bohrung ausgebildet. Das stiftförmige Führungselement kann in der Bohrung passgenau geführt werden und die als Bohrung ausgeführte Führungsaufnahme ist gut vor Verschmutzung und dadurch bedingten Funktionsstörungen geschützt.In the rifle barrel according to the invention, the at least one guide element is guided displaceably in a guide receptacle running parallel to the barrel bore in the rifle barrel. The guide element can thus be shifted between an extended guide position and an inserted firing position. The movement of the cartridge when it is inserted into the cartridge chamber is limited via the guide element and the cartridge is guided. In the firing position, the guide element is pushed into the barrel and is well protected there. The guide element is pin-shaped and the associated guide receptacle is designed as a bore. The pin-shaped guide element can be guided precisely in the bore and the guide receptacle designed as a bore is well protected from contamination and malfunctions caused by it.

In einer besonders zweckmäßigen Ausführung weist die Patronenführung zwei oberhalb des Patronenlagers angeordnete, zueinander parallele Führungsaufnahmen mit jeweils einem darin parallel zur Laufbohrung verschiebbaren Führungselement auf. Auf diese Weise ist eine besonders einfache und dennoch genaue Führung möglich. Die Führungselemente dienen dabei als Begrenzung, zwischen denen die Patrone, insbesondere das bei der Nachführung aus dem Magazin schräg nach oben ragende Geschoss, geführt und so die Patrone sicher bis in das Patronenlager gefördert werden kann. Anstelle der beiden Führungselemente kann aber auch nur ein, z.B. als Schieber ausgeführtes, einzelnes Führungselement mit einer an die Außenkontur der Patronen angepassten Innenkontur zum Einsatz gelangen.In a particularly expedient embodiment, the cartridge guide has two guide receptacles which are arranged above the cartridge chamber and are parallel to one another and each have a guide element therein which can be displaced parallel to the barrel bore. In this way, a particularly simple and yet precise guidance is possible. The guide elements serve as a delimitation between which the cartridge, in particular the projectile protruding obliquely upward from the magazine during tracking, can be guided and the cartridge can thus be safely conveyed into the chamber. Instead of the two guide elements, however, it is also possible to use only a single guide element, e.g. designed as a slide, with an inner contour adapted to the outer contour of the cartridges.

Vorzugsweise sind die mindestens eine Führungsaufnahme und das darin verschiebbare Führungselement oberhalb des Patronenlagers angeordnet. Dadurch können Patronen geführt werden, die von einem unterhalb des Laufs angeordneten Magazin nachgeführt werden.The at least one guide receptacle and the guide element which can be displaced therein are preferably arranged above the cartridge chamber. In this way, cartridges can be guided, which are tracked by a magazine arranged below the barrel.

Vorzugsweise ist das Führungselement innerhalb der Führungsaufnahme zwischen einer eingeschobenen Feuerstellung und einer ausgefahrenen Führungsstellung axial verschiebbar geführt. Das Führungselement wird zweckmäßigerweise durch ein Federelement in die ausgefahrene Führungsstellung gedrückt. Das in einer vorteilhaften Ausführung z.B. als Schraubendruckfeder ausgebildete Federelement kann in der Führungsaufnahme angeordnet sein. Durch ein dem Führungselement zugeordnetes Anschlagelement kann die Verschiebung des Führungselements innerhalb der Führungsaufnahme bei der Bewegung in die ausgefahrene Führungsstellung begrenzt und dadurch ein Herausfallen des Führungselements aus der Führungsaufnahme verhindert werden. Das z.B. als Kopf einer Schraube ausgeführte Anschlagelement kann mit einer Kante bzw. Stufe an dem Führungselement zusammenwirken.The guide element is preferably guided axially displaceably within the guide receptacle between an inserted firing position and an extended guide position. The guide element is expediently pressed into the extended guide position by a spring element. The spring element, designed as a helical compression spring in an advantageous embodiment, can be arranged in the guide receptacle. A stop element assigned to the guide element can limit the displacement of the guide element within the guide receptacle during the movement into the extended guide position and thereby prevent the guide element from falling out of the guide receptacle. The stop element, for example designed as the head of a screw, can interact with an edge or step on the guide element.

In einer weiteren Ausgestaltung kann die Patronenführung ferner eine in der Öffnung des Gewehrlaufs angeordnete Zuführrampe aufweisen. Durch die Zuführrampe wird der Spielraum für die Patrone innerhalb der Öffnung weiter eingeschränkt und somit die Möglichkeiten für ein Verkanten oder Verklemmen weiter verringert. Diese Zuführrampe ist zweckmäßigerweise austauschbar und kann bei Bedarf so an unterschiedliche Patronen angepasst werden. Bevorzugt weist die Zuführrampe dabei eine in Richtung des Patronenlagers ansteigende Einführschräge für das sichere Einführen der Patrone in das Patronenlager auf.In a further embodiment, the cartridge guide can also have a feed ramp arranged in the opening of the gun barrel. The feed ramp further restricts the clearance for the cartridge within the opening and thus further reduces the possibility of tilting or jamming. This The feed ramp is expediently exchangeable and can thus be adapted to different cartridges if necessary. The feed ramp preferably has an insertion bevel that rises in the direction of the cartridge chamber for the safe insertion of the cartridge into the cartridge chamber.

Die Erfindung betrifft außerdem ein Repetiergewehr mit einem derartigen Gewehrlauf und einem Verschluss, der eine mit dem Gewehrlauf zusammenwirkende Kammer enthält. Durch die in die Öffnung am hinteren Ende des Gewehrlaufs eingreifende Kammer ist das mindestens eine Führungselement verschiebbar und kann in die Führungsaufnahme eingedrückt werden.The invention also relates to a repeating rifle with such a rifle barrel and a breech which contains a chamber cooperating with the rifle barrel. The at least one guide element is displaceable through the chamber engaging in the opening at the rear end of the gun barrel and can be pressed into the guide receptacle.

In dem Systemkasten 7 ist außerdem eine herausnehmbare Abzugseinheit 14 mit einem Magazin 15 zur Aufnahme mehrerer Patronen angeordnet.How out Figure 2 As can be seen, the rifle barrel 1 fastened to a system case 7 via bolt-shaped retaining elements 6 contains, in a manner known per se, a barrel bore 8 with a cartridge chamber 9 and an opening 10 at a barrel end 11 of the rifle barrel 1 for receiving a chamber 12 of a slide that is slidable on the system case 7 13. A removable trigger unit 14 with a magazine 15 for receiving several cartridges is also arranged in the system box 7.

In den unterschiedlichen Schnittansichten von Figur 3 und 4 ist erkennbar, dass die beiden stiftförmigen Führungselemente 4 und die hier als Schraubendruckfeder ausgebildeten Federelemente 5 in zwei oberhalb der Laufbohrung 8 angeordneten und zu dieser parallelen Führungsaufnahmen 16 angeordnet sind. Die sowohl zueinander parallelen als auch parallel zu Laufbohrung verlaufenden Führungsaufnahmen 16 sind in dem gezeigten Ausführungsbeispiel als Bohrungen ausgebildet. In den insbesondere als Sacklochbohrungen ausgebildeten Führungsaufnahmen 16 sind die beiden stiftförmigen Führungselemente 4 verschiebbar geführt und werden durch die beiden Federelemente 5 in Richtung des hinteren Endes des Gewehrlaufs 1 gedrückt. Die Führungsaufnahmen 16 sind derart ausgebildet, dass sie die Federelemente 5 und die stiftförmigen Führungselemente 4 vollständig aufnehmen können und die stiftförmigen Führungselemente 4 entgegen der Kraft der Federelemente 5 bis zum Boden 17 der Öffnung 10 am Laufende 11 des Laufs eingedrückt werden können. Die stiftförmigen Führungselemente 4 sind innerhalb der Führungsaufnahmen 16 zwischen einer eingeschobenen Feuerstellung und einer ausgefahrenen Führungsstellung axial verschiebbar geführt.In the different sectional views of Figures 3 and 4 it can be seen that the two pin-shaped guide elements 4 and the spring elements 5, which are designed here as helical compression springs, are arranged in two guide receptacles 16 arranged above the barrel bore 8 and parallel to it. The guide receptacles 16, which are both parallel to one another and also run parallel to the barrel bore, are designed as bores in the exemplary embodiment shown. The two pin-shaped guide elements 4 are guided displaceably in the guide receptacles 16, which are designed in particular as blind holes, and are pressed by the two spring elements 5 in the direction of the rear end of the gun barrel 1. The guide receptacles 16 are designed in such a way that they can completely accommodate the spring elements 5 and the pin-shaped guide elements 4 and the pin-shaped guide elements 4 can be pressed against the force of the spring elements 5 to the bottom 17 of the opening 10 at the barrel end 11 of the barrel. The pin-shaped guide elements 4 are guided axially displaceably within the guide receptacles 16 between an inserted firing position and an extended guide position.

Wie aus Figur 4 hervorgeht, ist in dem Gewehrlauf 1 außerdem ein mit den Führungselementen 4 zusammenwirkendes Anschlagelement 18 zur Begrenzung der Bewegung der stiftförmigen Führungselemente 4 in Richtung der Kammer 12 bzw. des hinteren Endes des Gewehrlaufs 1 angeordnet. Bei der gezeigten Ausführung wird das Anschlagelement 18 durch eine in eine Gewindebohrung 19 im Boden 17 der Öffnung 10 in Axialrichtung des Gewehrlaufs 1 eingeschraubte Halteschraube gebildet.How out Figure 4 As can be seen, a stop element 18 interacting with the guide elements 4 is also arranged in the gun barrel 1 to limit the movement of the pin-shaped guide elements 4 in the direction of the chamber 12 or the rear end of the gun barrel 1. In the version shown, the Stop element 18 is formed by a retaining screw screwed into a threaded hole 19 in the bottom 17 of the opening 10 in the axial direction of the gun barrel 1.

In Figur 1 ist erkennbar, dass das schraubenförmige Anschlagelement 18 mit seinem verbreiterten Kopf 20 in einer Ausfahrstellung der Führungselemente 4 zur Anlage an einer Stufe 21 der Führungselemente 4 gelangt. Die Stufe 21 an den Führungselementen 4 wird bei der gezeigten Ausführung durch seitliche Abflachungen 22 an den Führungselementen 4 gebildet.In Figure 1 it can be seen that the screw-shaped stop element 18 with its widened head 20 comes to rest on a step 21 of the guide elements 4 in an extended position of the guide elements 4. In the embodiment shown, the step 21 on the guide elements 4 is formed by lateral flattened areas 22 on the guide elements 4.

An dem Laufende 11 ist innerhalb der Öffnung 10 ferner die Zuführrampe 3 für die Zuführung einer Patrone zum Patronenlager 12 angeordnet. Die unterhalb des Patronenlagers 12 angeordnete Zuführrampe 3 ist über eine Schraube 23 fixiert und weist eine in Richtung des Patronenlagers 12 ansteigende Einführschräge 24 mit einer an die Außenkontur der Patrone angepassten halbschalenförmigen Innenkontur auf.At the barrel end 11, the feed ramp 3 for feeding a cartridge to the cartridge chamber 12 is also arranged within the opening 10. The feed ramp 3 arranged below the cartridge chamber 12 is fixed by a screw 23 and has an insertion bevel 24 that rises in the direction of the cartridge chamber 12 and has a half-shell-shaped inner contour that is adapted to the outer contour of the cartridge.

Fig. 5 zeigt die Zuführung einer Patrone in den erfindungsgemäßen Gewehrlauf 1. Über die Kammer 12 des nach der Abgabe eines Schusses zum Repetieren und Auswerfen einer leeren Hülse zurückgezogenen Verschlusses 13 wird eine aus dem Magazin 15 nachgeführte neue Patrone 25 durch erneutes Vorschieben des Verschlusses 13 nach vorne in Richtung des Patronenlagers 9 geschoben. Dabei wird die Patrone 25 über die Zuführrampe 3 zunächst schräg nach oben gelenkt. Wenn das Geschoss 26 der neuen Patrone 25 dabei zur Anlage an der Unterseite der in die Öffnung 10 ragenden Führungselementen 4 gelangt, wird die Patrone 25 umgelenkt und in das Patronenlager 9 geleitet. Durch die Führungselemente 4 wird dabei das sichere Einführen der Patrone 25 in das Patronenlager 9 ohne ein Verklemmen oder Verkanten gewährleistet. Beim weiteren Vorschieben der Verschlusses 13 wird von der Kammer 12 nicht nur die Patrone 25 vollständig in das Patronenlager 9, sondern auch die Führungselemente 4 werden entgegen der Kraft der Federelemente 5 eingedrückt, bis die Kammer 12 zur Anlage am Boden 17 der Öffnung 10 kommt und gegenüber dem Gewehrlauf 1 verriegelt wird. Sobald der Verschluss 13 und damit auch die Kammer 12 wieder zurückgezogen werden, gelangen die stiftförmigen Führungselemente 4 wieder in die in Figur 5 gezeigte Ausgangsposition. Dann kann ein erneuter Nachladevorgang erfolgen. Fig. 5 shows the feeding of a cartridge into the rifle barrel 1 according to the invention. Via the chamber 12 of the slide 13, which is retracted after a shot has been fired for repeating and ejecting an empty case, a new cartridge 25 fed from the magazine 15 is pushed forward in Pushed towards the chamber 9. The cartridge 25 is initially steered obliquely upwards via the feed ramp 3. When the projectile 26 of the new cartridge 25 comes to rest on the underside of the guide elements 4 protruding into the opening 10, the cartridge 25 is deflected and guided into the cartridge chamber 9. The guide elements 4 ensure the safe insertion of the cartridge 25 into the cartridge chamber 9 without jamming or tilting. As the breech 13 is pushed forward, the chamber 12 not only pushes the cartridge 25 completely into the chamber 9, but also the guide elements 4 are pressed against the force of the spring elements 5 until the chamber 12 comes to rest on the bottom 17 of the opening 10 and is locked against the gun barrel 1. As soon as the closure 13 and thus also the chamber 12 are withdrawn again, the pin-shaped guide elements 4 move back into the FIG Figure 5 shown starting position. Then another reloading process can take place.
