Description

Die Erfindung betrifft eine Patronenzuführvorrichtung an einer selbsttätigen Feuerwaffe mit einem Waffenrohr, enthaltend:

  • - einen Verschluss, der aus einer hintersten in eine vorderste Stellung verschiebbar ist;
  • - einen Patronenzuführkanal, der eine Seitenwand aufweist;
  • - einen zur Waffenachse parallelen Schlitz, der sich in dieser Seitenwand befindet und in den eine im Patronenzuführkanal befindliche, durch den Verschluss in das Waffenrohr einzuschiebende Patrone teilweise hineinragt;
  • - Mittel zum Zuführen der Patrone zum Schlitz und zum Halten der Patrone, sodass sie teilweise in den Schlitz hineinragt, wenn sie zum Einschieben ins Waffenrohr durch den Verschluss bereit ist;
  • - einen schwenkbaren Einlegehebel zum Verschieben der Patrone, bis sie teilweise in den Schlitz hineinragt.
The invention relates to a cartridge feeding device on an automatic firearm with a weapon barrel, comprising:
  • - A closure that can be moved from a rearmost position to a forwardmost position;
  • - a cartridge feed channel having a side wall;
  • - A slot parallel to the weapon axis, which is located in this side wall and into which a cartridge located in the cartridge feed channel, which can be inserted through the breech into the gun barrel, partially protrudes;
  • Means for feeding the cartridge to the slot and for holding the cartridge so that it partially projects into the slot when it is ready to be inserted into the weapon barrel through the breech;
  • - A pivoting insertion lever for moving the cartridge until it partially protrudes into the slot.

Bei einer bekannten Patronenzuführvorrichtung dieser Art (siehe CH-PS 579 763, DE-PS 2 521 034, US-PS 3 973 467) ist ein Förderkanal vorhanden, dessen Seitenwand einen zur Waffenachse parallelen Schlitz aufweist, in den eine im Förderkanal befindliche durch den Verschluss in das Waffenrohr einzuschiebende Patrone teilweise hineinragt. Zwei Führungsarme der Zuführmittel drükken durch eine Feder die genannte Patrone senkrecht zur Förderrichtung gegen den genannten Schlitz. Auf den der Patrone gegenüber liegenden Seiten der Führungsarme ist eine schwenkbare Klinke angeordnet, die einen Nocken mit Steuerfläche aufweist, der zur Betätigung der Klinke dient. Durch diese Klinke sind die Führungsarme während des Einschiebens der Patrone hinterstellt.In a known cartridge supply device of this type (see CH-PS 579 763, DE-PS 2 521 034, US-PS 3 973 467), a delivery channel is provided, the side wall of which has a slot parallel to the weapon axis, into which a located in the delivery channel through the Part of the cartridge to be inserted into the weapon barrel protrudes. Two guide arms of the feed means press the said cartridge against the slot perpendicular to the conveying direction by means of a spring. On the sides of the guide arms opposite the cartridge, a pivotable pawl is arranged which has a cam with a control surface which serves to actuate the pawl. Through this pawl, the guide arms are positioned during the insertion of the cartridge.

Diese bekannte Vorrichtung hat folgenden Nachteil. Zum Zuführen der Patrone in den genannten Schlitz steht nur sehr wenig Zeit zur Verfügung. Die Patrone kann in diesen Schlitz nur eingelegt werden, wenn der Verschluss sich im Bereich seiner hintersten Stellung befindet, denn nur solange der Verschluss sich hinter der Patrone befindet, kann die Patrone derart in den Schlitz eingelegt werden, dass sie zuverlässig vom Verschlusskopf erfasst und in das Waffenrohr eingeschoben werden kann. Je grösser jedoch die Kadenz der Feuerwaffe ist, um so kürzer ist die Zeit, die zur Verfügung steht, die Patrone in die gewünschte Stellung zu bringen. Es genügt daher nicht mehr, dass zwei Führungsarme durch eine Feder die Patrone senkrecht zur Förderrichtung gegen den genannten Schlitz drücken. Die Beschleunigungskräfte, die erforderlich sind, um die Patrone in so kurzer Zeit zu verschieben, sind so gross, dass auch eine starke Feder nicht mehr genügt.This known device has the following disadvantage. Very little time is available to feed the cartridge into the slot mentioned. The cartridge can only be inserted into this slot when the breech is in the area of its rearmost position, because only as long as the breech is behind the cartridge can the cartridge be inserted into the slot in such a way that it is reliably gripped by the breech head and in the gun barrel can be inserted. However, the greater the cadence of the firearm, the shorter the time available to bring the cartridge into the desired position. It is therefore no longer sufficient for two guide arms to press the cartridge against the slot mentioned perpendicularly to the conveying direction by means of a spring. The acceleration forces required to move the cartridge in such a short time are so great that even a strong spring is no longer sufficient.

Die Erfindung löst die Aufgabe, eine Vorrichtung zu schaffen, die zum Zuführen der Patrone zum Schlitz, aus dem sie durch den Verschluss ins Waffenrohr einschiebbar ist, ohne die erwähnte Federkraft arbeitet.The invention solves the problem of creating a device which works for feeding the cartridge to the slot, from which it can be inserted into the weapon barrel through the breech, without the spring force mentioned.

Die Vorrichtung, mit der diese Aufgabe gelöst wird, ist dadurch gekennzeichnet,

  • - dass der schwenkbare Einlegehebel zwei Arme aufweist;
  • - dass der Verschluss eine Steuerkurve zum Verschwenken des Einlegehebels aufweist;
  • - dass der eine Arm des Einlegehebels sich auf der Steuerkurve des Verschlusses abstützt;
  • - dass der andere Arm des Einlegehebels sich auf dem hinteren Ende der Patrone abstützt;
  • - dass der Einlegehebel um eine Achse schwenkbar am Patronenzuführkanal gelagert ist; und
  • - dass die Form der Steuerkurve so gewählt ist, dass der Einlegehebel in der hintersten Stellung des Verschlusses mit seinem einen Arm die Patrone teilweise in den Schlitz der Seitenwand drückt.
The device with which this object is achieved is characterized in that
  • - That the pivoting insertion lever has two arms;
  • - That the closure has a control curve for pivoting the insertion lever;
  • - That the one arm of the insertion lever is supported on the control curve of the closure;
  • - that the other arm of the insertion lever is supported on the rear end of the cartridge;
  • - That the insertion lever is pivotally mounted about an axis on the cartridge feed channel; and
  • - That the shape of the control cam is chosen so that the insertion lever in the rearmost position of the closure with one arm presses the cartridge partially into the slot in the side wall.

Diese Vorrichtung hat den Vorteil, dass die Patrone zwangsläufig beim Rücklauf des Verschlusses durch den Einlegehebel in den Schlitz hineingedrückt wird und sich zuverlässig an der richtigen Stelle befindet, sobald die Patrone durch die Kante des Verschlusses ins Waffenrohr eingeschoben wird.This device has the advantage that the cartridge is forced into the slot by the insertion lever when the breech is retracted and is reliably in the correct position as soon as the cartridge is inserted into the weapon barrel through the edge of the breech.

In der US-A-2 875 671 ist zwar ein zweiarmiger Einlegehebel beschrieben, an dessen einen Arm stützt sich die Patrone jedoch mit ihrem vorderen Ende ab. Eine Steuerkurve dient zur Betätigung dieses einen Armes. Der andere Arm ist ausschliesslich durch eine Feder belastet. Ein seitliches Abgleiten der Patrone vom Verschluss kann durch diesen Einlegehebel nicht verhindert werden. Die Steuerkurve ist nicht am Verschluss angeordnet, sondern ist mit dem rücklaufbeweglichen Waffenrohr verbunden.A two-armed insertion lever is described in US Pat. No. 2,875,671, but the cartridge is supported on its one arm with its front end. A control cam serves to actuate this one arm. The other arm is loaded exclusively by a spring. The insertion lever cannot prevent the cartridge from sliding off the side. The control cam is not arranged on the breech, but is connected to the retractable weapon barrel.

In der US-A-2 529 822 ist ebenfalls ein Einlegehebel beschrieben, der zwei Arme aufweist, von denen der eine Arm die Patrone umlenkt und der andere Arm von der Steuerkurve des Verschlusses verschwenkt wird. Gerade bei dieser Vorrichtung ist Gefahr, dass die Patrone vom Verschluss abgleitet, wenn die Patrone durch den Verschluss ins Waffenrohr eingeschoben wird, besonders gross. Der Einlegehebel ist aber nicht in der Lage, dieses Abgleiten zu verhindern, da er nicht am hinteren Ende der Patrone, d.h. im Bereich des Hülsenbodens, angreift.US-A-2 529 822 also describes an insertion lever which has two arms, one arm of which deflects the cartridge and the other arm is pivoted by the control curve of the closure. With this device in particular, there is a particularly great risk that the cartridge will slide off the breech when the cartridge is inserted through the breech into the weapon barrel. However, the insertion lever is not able to prevent this sliding off, since it is not at the rear end of the cartridge, i.e. in the area of the sleeve base.

In der CH-A-253 497 ist eine Patronenzuführvorrichtung beschrieben, bei welcher die Steuerfläche des Verschlusses eine Steuerkurve ist, die eine gegenseitige Gebundenheit der Bewegungen erlaubt. Ein spezieller Einlegehebel ist jedoch nicht vorhanden.In CH-A-253 497 a cartridge feeding device is described in which the control surface of the closure is a control curve which allows the movements to be mutually dependent. However, there is no special insertion lever.

In der FR-A-1 066 513 ist eine Patronenzuführvorrichtung beschrieben, bei der unter Vermeidung einer Feder eine zwangsläufige Bewegung der Zuführmittel mit dem Verschluss vorhanden ist.FR-A-1 066 513 describes a cartridge feed device in which there is an inevitable movement of the feed means with the closure while avoiding a spring.

In der US-A-2 486 878 ist ebenfalls eine Patronenzuführvorrichtung beschrieben, welche einen schwenkbaren Einlegehebel aufweist, der jedoch nur durch eine Feder belastet ist, sodass beim Einschieben einer Patrone ins Waffenrohr durch den Verschluss die Gefahr besteht, dass die Feder zu schwach ist und die Patrone vom Verschluss abgleitet.US Pat. No. 2,486,878 also describes a cartridge feeder device which has a pivotable insertion lever which, however, is only loaded by a spring, so that when a cartridge is inserted into the weapon barrel through the breech there is a risk that the spring is too weak and the cartridge slides off the cap.

Vorzugsweise besitzen die Zuführmittel eine Hinterstellklinke, welche die Patrone hinterstellt, sobald sie durch den Einlegehebel in den Schlitz eingelegt ist.The feed means preferably have a rear pawl which backs the cartridge as soon as it is inserted into the slot by the insertion lever.

Ein Ausführungsbeispiel der erfindungsgemässen Patronenzuführvorrichtung ist anhand der beigefügten Zeichnung im folgenden ausführlich beschrieben. Es zeigt:

  • Fig. 1 einen Längsschnitt durch einen Teil einer Feuerwaffe;
  • Fig. 2 denselben Längsschnitt wie in Fig. 1, zu einem anderen Zeitpunkt der Patronenzufuhr.
  • Fig. 3 eine Seitenansicht der in Fig. 2 dargestellten Vorrichtung und
  • Fig. 4 eine Ansicht in Richtung des Pfeiles A in Fig. 3.
An embodiment of the cartridge feeding device according to the invention is described in detail below with reference to the accompanying drawing. It shows:
  • 1 shows a longitudinal section through part of a firearm.
  • Fig. 2 the same longitudinal section as in Fig. 1, at a different time of the cartridge supply.
  • Fig. 3 is a side view of the device shown in Fig. 2 and
  • 4 is a view in the direction of arrow A in FIG. 3rd

In Fig. 1 und 2 ist von einer Feuerwaffe ein Teil des Waffengehäuses 10 dargestellt sowie ein Teil des Waffenrohres 11. Am Waffengehäuse 10 sind zwei Patronenzufuhrkanäle 12 und 13 um Zapfen 14 schwenkbar befestigt. Der Patronenzuführkanal 12 ist ausgeschwenkt, so dass aus diesem Kanal 12 keine Patronen der Waffe zugeführt werden können. Der Patronenzuführkanal 13 hingegen befindet sich in Arbeitsstellung, so dass die Patronen 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 immer der eine oder andere Patronenzuführkanal (12, 13) sich in Arbeitsstellung befindet, während gleichzeitig der andere ausgeschwenkt ist.1 and 2, a part of the weapon housing 10 and a part of the weapon barrel 11 are shown of a firearm. Two cartridge feed channels 12 and 13 are pivotably attached to the weapon housing 10 about pins 14. The cartridge feed channel 12 is pivoted out, so that no cartridges of the weapon can be fed from this channel 12. The cartridge feed channel 13, on the other hand, is in the working position, so that the cartridges 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 swung out.

Im Waffengehäuse 10 ist ein Verschluss 15 verschiebbar gelagert. Dieser Verschluss 15 ist in Fig. 1 in seiner hintersten und in Fig. 2 in seiner vordersten Stellung dargestellt.A lock 15 is slidably mounted in the weapon housing 10. This closure 15 is shown in Fig. 1 in its rearmost position and in Fig. 2 in its forwardmost position.

Der Verschluss 15 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 Verschlusses 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 16 entriegelt. Die Verschiebung des Verschlusses 15 erfolgt in der üblichen Weise durch eine nicht dargestellte Vorholfeder und den Gasdruck. Auch die Förderung der Patronengurte in den Patronenzuführkanälen 12 und 13 erfolgt in der üblichen Weise. Beides ist daher hier nicht näher beschrieben.The closure 15 has a closure head 16 and a control piece 17 as well as two bolts 18. The control piece 17 is arranged displaceably in the closure head 16. In the foremost position of the breech 15, the control piece 17 protrudes between the two bolts 18 and presses the bolts 18 into recesses 19 in the weapon barrel 11, so that the bolt 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 16 is unlocked. The displacement of the closure 15 is carried out in the usual way by a not shown spring and 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 in more detail here.

Bei der Verschiebung des Verschlusses 15 aus seiner hintersten in seine vorderste Stellung (in Fig. 1 und 2 von rechts nach links), stösst der Verschluss 15 mit der Kante 22 gegen den Boden 36 der Patrone 23, die sich im Patronenzuführkanal 13 in einem Schlitz 35 einer Seitenwand 34 des Patronenzuführkanals 13 befindet (Fig. 4). Die Patronenachse ist gegenüber der Waffenachse 32 (Fig. 2) geneigt. Die Patrone 23 wird an einer Klinke 24 abgelenkt und in das Waffenrohr 11 hineingeschoben. Anschliessend wird die Patrone 23 durch einen Zündstift 25 des Steuerstückes 17 gezündet.When the closure 15 is displaced from its rearmost position to its foremost position (from right to left in FIGS. 1 and 2), the closure 15 abuts with the edge 22 against the bottom 36 of the cartridge 23, which is located in the cartridge feed channel 13 in a slot 35 is a side wall 34 of the cartridge feed channel 13 (Fig. 4). The cartridge axis is inclined with respect to the weapon axis 32 (FIG. 2). The cartridge 23 is deflected at a pawl 24 and pushed into the weapon barrel 11. The cartridge 23 is then ignited by an ignition pin 25 of the control piece 17.

Beim Einschieben der Patrone 23 durch eine Feder in den Schlitz 35 (Fig. 4) der Seitenwand 34 des Patronenzuführkanales 13 bestand bei den bekannten Vorrichtungen die Gefahr, dass die Feder nicht in der Lage war, die Patronen 23 rechtzeitig und vollständig in den Schlitz 35 hineinzudrücken, so dass beim Verlauf des Verschlusses 15 die Patrone 23 von der Kante 22 des Verschlusskopfes abrutschte und zwischen Verschluss 15 und Waffenrohr 11 eingeklemmt wurde. Um dieses Abrutschen zu verhindern, wurden daher bis jetzt möglichst starke Federn verwendet. Bei wachsender Kadenz ist jedoch die Zeit, die zur Verfügung steht, um die Patrone 23 in den Schlitz 35 zu drücken, so kurz, dass eine Feder nicht mehr in der Lage ist, die Patrone rechtzeitig und zuverlässig in den Schlitz hineinzudrücken.When the cartridge 23 was inserted into the slot 35 (FIG. 4) of the side wall 34 of the cartridge feed channel 13 by a spring, there was a risk in the known devices that the spring was not able to insert the cartridges 23 completely and in time into the slot 35 to push it in, so that during the course of the breech 15 the cartridge 23 slipped off the edge 22 of the breech head and was clamped between the breech 15 and the barrel 11. So far, springs as strong as possible have been used to prevent this slipping. With increasing cadence, however, the time available to push the cartridge 23 into the slot 35 is so short that a spring is no longer able to press the cartridge into the slot reliably and in good time.

Erfindungsgemäss sind daher an jedem Patronenzuführkanal 12 und 13 je ein Einlegehebel 20 und 21 um eine Achse 26 und je eine Hinterstellklinke 27 um eine Achse 28 schwenkbar gelagert. Der zweiarmige Einlegehebel 20, 21 stützt sich gemäss Fig. 1 mit seinem Arm 30 auf einer Steuerkante 29 des Verschlusskopfes 26 ab. Mit dem anderen Arm 31 des Einlegehebels 21 wird die Patrone 23 in den Schlitz 35 (Fig. 4) hineingedrückt. Wenn sich der Verschlusskopf 16 in seiner hintersten Stellung befindet, stützt sich der Einlegehebel 21 mit seinem Arm 30 auf der höchsten Stelle der Steuerkurve 29 des Verschlusskopfes 16 ab. Die Patrone 23 wird dabei durch den Arm 31 des Einlegehebels 21 soweit gegen die Waffenachse 32, d. h. in den Schlitz 35 gedrückt, dass die Hinterstellklinke 27 einrasten kann, wie aus Fig. 4 ersichtlich ist. Eine Feder 33, die in einem Gehäuse am Zuführkanal 13 befestigt ist (Fig. 1), hat das Bestreben, den Einlegehebel 21 mit seinem Arm 30 gegen die Steuerkurve 29 zu drücken. Durch den Einlegehebel 20 bezw. 21 wird somit gewährleistet, dass die Patrone 23 vollständig in den Schlitz 35 eingeschoben ist und somit die zum Einschieben ins Waffenrohr 11 erforderliche Stellung erreicht hat, bevor der Verschlusskopf 16 aus seiner hintersten Lage beim Vorlauf mit seiner Kante 22 gegen den Boden 36 der Patrone 23 stösst. Die Hinterstellklinke 27 gewährleistet, dass beim Einschieben der Patrone 23 ins Waffenrohr 11 die Patrone 23 nicht mehr von der Kante 22 des Verschlusskopfes 16 abrutschen kann.According to the invention, therefore, each insertion lever 20 and 21 is mounted on each cartridge feed channel 12 and 13 so as to be pivotable about an axis 26 and one rear pawl 27 about an axis 28. The two-armed insertion lever 20, 21 is supported according to FIG. 1 with its arm 30 on a control edge 29 of the closure head 26. With the other arm 31 of the insertion lever 21, the cartridge 23 is pressed into the slot 35 (FIG. 4). When the closure head 16 is in its rearmost position, the insertion lever 21 is supported with its arm 30 on the highest point of the control curve 29 of the closure head 16. The cartridge 23 is so far by the arm 31 of the insertion lever 21 against the weapon axis 32, d. H. pressed into the slot 35 so that the rear pawl 27 can engage, as can be seen from FIG. 4. A spring 33, which is fastened in a housing on the feed channel 13 (FIG. 1), tends to press the insertion lever 21 with its arm 30 against the control cam 29. By the insertion lever 20 or. 21 thus ensures that the cartridge 23 is fully inserted into the slot 35 and thus has reached the position required for insertion into the weapon barrel 11 before the breech head 16 with its edge 22 against its base 36 against the bottom 36 of the cartridge 23 during its advance bumps. The rear pawl 27 ensures that when the cartridge 23 is inserted into the weapon barrel 11, the cartridge 23 can no longer slide off the edge 22 of the breech head 16.
