Description

Die Erfindung betrifft einen Munitionsbehälter, insbesondere ein Trommelmagazin, mit einem Abteil zur Aufnahme einer Schleife eines Patronengurtes, die aus zwei nebeneinander angeordneten Schleifenteilen besteht, wobei jeder Schleifenteil an einer Seitenwand des Abteiles anliegt.The invention relates to an ammunition container, in particular a drum magazine, with a compartment for receiving a loop of a cartridge belt, which consists of two loop parts arranged next to one another, each loop part abutting a side wall of the compartment.

Bei einem bekannten Munitionsbehälter dieser Art (s. CH-A Nr. 577669) weist das Abteil einen zahnstangenartigen Träger auf und die Lücken dieses Trägers dienen zurAufnahme je einer Patrone des einen Schleifenteiles.In a known ammunition container of this type (see CH-A No. 577669), the compartment has a rack-like carrier and the gaps of this carrier serve to accommodate one cartridge of each loop part.

Dieser bakannte Munitionsbehälter hat den Nachteil, dass in jedem Abteil nur die Patronen des einen Schleifenteiles in den Lücken des zahnstangenartigen Trägers aufgenommen werden können. Es ist daher nicht möglich, die Patronen des anderen Schleifenteiles gegen unbeabsichtigte Verschiebung zu sichern. Dies ist besonders dann von Bedeutung, wenn die Spitze der Patronen empfindlich ist und die Patronenspitze nicht zur Führung der Patronen im Munitionsbehälter verwendet werden darf. Insbesondere bei einem Trommelmagazin besteht dann die Gefahr, dass sich der Patronengurt unbeabsichtigter Weise gegen das Zentrum des Trommelmagazines bewegt, sich im schmäler werdenden Abteil verklemmt und die Entnahme des Patronengurtes aus dem Munitionsbehälter behindert oder verunmöglicht.This known ammunition container has the disadvantage that only the cartridges of one loop part can be accommodated in the gaps of the rack-like carrier in each compartment. It is therefore not possible to secure the cartridges of the other loop part against unintentional displacement. This is particularly important if the tip of the cartridges is sensitive and the tip of the cartridge must not be used to guide the cartridges in the ammunition container. In particular in the case of a drum magazine, there is then the risk that the cartridge belt moves unintentionally against the center of the drum magazine, jams in the narrowing compartment and hinders or makes it impossible to remove the cartridge belt from the ammunition container.

Die Aufgabe, welche durch die vorliegende Erfindung gelöst werden soll, besteht in der Schaffung eines Munitionsbehälters, bei dem eine zuverlässige Entnahme des Patronengurtes aus den Abteilen des Munitionsbehälters, insbesondere des Trommelmagazins für beide Teile der Schleife des Patronengurtes gewährleistet ist, so dass die Entnahme ohne grosse Kräfte möglich ist und die Schleife des Patronengurtes in den Abteilen des Munitionsbehälters gegen jede unbeabsichtigte Verschiebung gesichert ist.The object which is to be achieved by the present invention is to provide an ammunition container in which a reliable removal of the cartridge belt from the compartments of the ammunition container, in particular the drum magazine, is ensured for both parts of the loop of the cartridge belt, so that the removal without large forces are possible and the loop of the cartridge belt in the compartments of the ammunition container is secured against any unintentional movement.

Diese Aufgabe ist mit dem erfindungsgemässen Munitionsbehälter dadurch gelöst, dass zwischen jedem Schleifenteil des Patronengurtes und der Seitenwand des Abteiles ein Magnet angeordnet ist, der an der Seitenwand befestigt ist und den Schleifenteil anzieht und gegen Verschiebung ins Zentrum des Trommelmagazins sichert.This object is achieved with the ammunition container according to the invention in that a magnet is arranged between each loop part of the cartridge belt and the side wall of the compartment, which is fastened to the side wall and attracts the loop part and secures it against displacement into the center of the drum magazine.

Ein Ausführungsbeispiel des erfindungsgemässen Munitionsbehälters ist anhand der beigefügten Zeichnung im folgenden ausführlich beschrieben. Es zeigen:

  • Fig. 1 eine schaubildliche Darstellung eines Trommelmagazines, und
  • Fig. 2 eine Ansicht eines Teiles des in Fig. 1 dargestellten Trommelmagazines in vergrössertem Massstab.
An embodiment of the ammunition container according to the invention is described in detail below with reference to the accompanying drawing. Show it:
  • Fig. 1 is a diagrammatic representation of a drum magazine, and
  • Fig. 2 is a view of part of the drum magazine shown in Fig. 1 on an enlarged scale.

Gemäss Fig. 1 weist das Trommelmagazin 10 eine Anzahl sektorförmige Abteile 11 auf, welche durch Seitenwände 12 voneinander getrennt sind. In jedem Abteil 11 des Trommelmagazins 10 befindet sich eine Schleife 13 eines Patronengurtes 14. In der Zeichnung sind nur zwei Abteile 11 mit Schleifen 13 des Patronengurtes 14 gefüllt, die übrigen Abteile 11 sind bereits entleert dargestellt. Jede Schleife 13 des Patronengurtes 14 besteht aus zwei vom oberen Rand der Seitenwände 12 herabhängenden Schleifenteilen 15 und 16, welche unten miteinander verbunden sind und welche an den Seitenwänden 12 der Abteile 11 des Trommelmagazins 10 anliegen. Ein Motor 26, der in der Zeichnung nur schematisch als Kreis angedeutet ist, dient zur Entnahme des Patronengurtes 14 und zur Zufuhr des Patronengurtes 14 zu einer in der Zeichnung nicht dargestellten Feuerwaffe. An einer der Seitenwände 12 sind in Fig. 1 noch zwei stabförmige Magnete 20 dargestellt. Selbstverständlich sind an jeder Seitenwand 12 des Trommelmagazins 10 zwei solche Stabmagnete 20 befestigt, die jedoch in der schematischen Darstellung gemäss Fig. 1 der Deutlichkeit halber weggelassen wurden.1, the drum magazine 10 has a number of sector-shaped compartments 11 which are separated from one another by side walls 12. In each compartment 11 of the drum magazine 10 there is a loop 13 of a cartridge belt 14. In the drawing, only two compartments 11 are filled with loops 13 of the cartridge belt 14, the remaining compartments 11 are already shown empty. Each loop 13 of the cartridge belt 14 consists of two loop parts 15 and 16 hanging from the upper edge of the side walls 12, which are connected to one another at the bottom and which abut the side walls 12 of the compartments 11 of the drum magazine 10. A motor 26, which is indicated only schematically as a circle in the drawing, serves to remove the cartridge belt 14 and to feed the cartridge belt 14 to a firearm, not shown in the drawing. Two rod-shaped magnets 20 are shown on one of the side walls 12 in FIG. 1. Of course, two such bar magnets 20 are fastened to each side wall 12 of the drum magazine 10, but these have been omitted in the schematic representation according to FIG. 1 for the sake of clarity.

Das Trommelmagazin 10 besitzt eine zylinderische Wand und einen Boden, die jedoch hier nicht dargestellt sind, da sie nicht Gegenstand der Erfindung sind.The drum magazine 10 has a cylindrical wall and a bottom, which are not shown here, however, since they are not the subject of the invention.

Gemäss Fig. 2 befindet sich jede Patrone 17 in einem Gurtglied 18. Die einzelnen Gurtglieder 18 sind in üblicher Weise miteinander verbunden und bilden den in Fig. 1 dargestellten Patronengurt 14. In Fig. 2 sind nur die drei Patronen 17-1,17-2 und 17-3 am oberen Ende eines Abteils 11 dargestellt, die in Fig. 1 mit den gleichen Bezugsziffern bezeichnet sind. Von den Seitenwänden 12 sind in Fig. 2 nur die oberen Stirnflächen 19 sichtbar. Jede Seitenwand 12 weist zwei Aussparungen 21 auf, in denen die Magnete 20 befestigt sind. Jeder Magnet 20 befindet sich in einer im Querschnitt U-förmigen Schiene 22 und weist selber einen rechteckigen Querschnitt auf. Der Magnet 20 bildet zusammen mit der Schiene 22 zwei Längsrillen 23, in welche zwei Nocken 24 des Gurtgliedes 18 hineinragen. Durch die Anziehungskraft des Magneten und durch die in den Längsrillen 23 geführten Nocken 24 wird verhindert, dass sich der Patronengurt 14 in unbeabsichtigter Weise gegen das Zentrum des Trommelmagazins 10 verschieben kann. Die Magnete 20 sind in nicht dargestellter Weise an den Seitenwänden 12 des Munitionsbehälters 10 angeschraubt. Zwischen Magnet 20 und Patronengurt 18 ist noch eine Platte 25 am Magnet 20 befestigt.According to FIG. 2, each cartridge 17 is located in a belt member 18. The individual belt members 18 are connected to one another in the usual manner and form the cartridge belt 14 shown in FIG. 1. In FIG. 2, only the three cartridges 17-1, 17- 2 and 17-3 at the upper end of a compartment 11, which are denoted in Fig. 1 with the same reference numerals. Only the upper end faces 19 of the side walls 12 are visible in FIG. 2. Each side wall 12 has two cutouts 21 in which the magnets 20 are fastened. Each magnet 20 is located in a rail 22 with a U-shaped cross section and itself has a rectangular cross section. The magnet 20 forms, together with the rail 22, two longitudinal grooves 23, into which two cams 24 of the belt member 18 protrude. The attractive force of the magnet and the cams 24 guided in the longitudinal grooves 23 prevent the cartridge belt 14 from being inadvertently displaced against the center of the drum magazine 10. The magnets 20 are screwed onto the side walls 12 of the ammunition container 10 in a manner not shown. A plate 25 is attached to the magnet 20 between the magnet 20 and the cartridge belt 18.

Die Kraft des Magnets 20 ist so gewählt, dass sich die Schleifen 13 des Patronengurtes 14 leicht in die Abteile 11 des Trommelmagazines 10 hineinschieben lassen und durch den Motor 26 auch leicht wieder herausziehen lassen. Die Kraft des Magneten 20 ist jedoch genügend gross, um jede unerwünschte Verschiebung des Patronengurtes 14 gegen das Zentrum des Trommelmagazines 10 zu verhindern.The force of the magnet 20 is selected so that the loops 13 of the cartridge belt 14 can be easily pushed into the compartments 11 of the drum magazine 10 and can also be easily pulled out again by the motor 26. However, the force of the magnet 20 is sufficiently large to prevent any undesired displacement of the cartridge belt 14 against the center of the drum magazine 10.

Für den Magneten 20 ist im dargestellten Beispiel ein Permanentmagnet verwendet worden. Es könnte auch ein Elektromagnet verwendet werden.A permanent magnet has been used for the magnet 20 in the example shown. An electromagnet could also be used.
