Description

Die Erfindung betrifft eine Vorrichtung zum radialen Sichern einer Patrone, welche durch einen zwangsläufig vor- und zurückbewegten Verschluss ins Waffenrohr eines fremdangetriebenen Geschützes eingeschoben wird, das mindestens ein in einem Waffengehäuse rotierendes Waffenrohr aufweist, mit einer Ausziehklaue am Verschluss, welche in eine Ausziehnut der Patronenhülse eingreift und ein Abgleiten der Patrone vom Verschlusskopf in einer radialen Richtung verhindert, mit einem der Ausziehklaue radial gegenüberliegendem Taststift zum Feststellen, ob eine Patrone ins Waffenrohr eingeschoben worden ist, welcher Taststift in axialer Richtung verschiebbar und von einer Feder belastet ist, welche das Bestreben hat, den Taststift in seiner vordersten Stellung zu halten und der bei vorhandener Patrone durch den Patronenhülsenboden, entgegen der Kraft der Feder, in seine hinterste Stellung verschiebbar ist.The invention relates to a device for the radial securing of a cartridge, which is inserted into the weapon barrel of an externally driven gun by an inevitably moved back and forth breech, which has at least one rotating barrel in a weapon barrel, with a pull-out claw on the breech which extends into an extraction groove of the cartridge case engages and prevents the cartridge from sliding off the breech head in a radial direction, with a stylus located radially opposite the pull-out claw to determine whether a cartridge has been inserted into the barrel, which stylus can be moved in the axial direction and is loaded by a spring which has the aim to hold the stylus in its foremost position and which, when the cartridge is present, can be moved through the cartridge case base, against the force of the spring, into its rearmost position.

Bei einem bekannten fremdangetriebenen Geschütz dieser Art (siene EP-A-0111240), ist eine Sicherheitsvorrichtung vorhanden, welche bei Zündverzögerung eine Entriegelung des Verschlusses verhindert. Denn bei Geschützen von der Art einer Gatling-Kanone besteht die Gefahr, dass bei einer Zündverzögerung die Patrone noch nach der Entriegelung das zwangsläufig vor- und zurückbewegten Verschlusses gezündet wird. Eine Zündung der Patrone nach der Entriegelung des Verschlusses ist unerwünscht. Diese Sicherheitsvorrichtung weist einen Taststift auf, um feststellen zu können, ob eine Patrone eingeschoben wurde oder nicht. Diese bekannte Vorrichtung spricht entweder auf den Gasdruck, oder auf den Rücklauf der Waffe, oder auf den Vorlauf der Waffe, oder auf eine Ausbuchtung der Patronenhülse an und bewirkt eine Trennung eines Verschlusskopfes von seinem Verschlussträger wobei der Verschlusskopf in seiner verriegelten Stellung bleibt, wenn die Patrone nicht rechtzeitig zündet, nachdem sie angestochen wurde. Dieses bekannte Geschütz weist jedoch keine Sicherheitsvorrichtung auf, welche beim Einschieben einer Patrone durch den Verschluss ins Waffenrohr ein radiales Abgleiten der Patrone vom Verschluss verhindern kann.In a known third-party gun of this type (see EP-A-0111240), a safety device is present which prevents the lock from being unlocked in the event of a delay in ignition. Because with guns of the type of a Gatling cannon, there is a risk that if the ignition is delayed, the cartridge will still be ignited after the unlocking of the breech, which is inevitably moved back and forth. Ignition of the cartridge after unlocking the breech is undesirable. This safety device has a stylus to determine whether a cartridge has been inserted or not. This known device speaks either to the gas pressure, or to the return of the Weapon, or on the advance of the weapon, or on a bulge of the cartridge case and causes a separation of a breech head from its breech carrier, the breech head remaining in its locked position if the cartridge does not ignite in time after being pierced. However, this known gun does not have a safety device which can prevent the cartridge from sliding radially from the breech when a cartridge is inserted through the breech into the weapon barrel.

Es ist üblich, an der Stirnseite des Verschlusses eine scheibenförmige Aussparung vorzusehen, in welche das hintere Ende der Patrone beim Einschieben ins Waffenrohr hineinragt, wodurch die Patrone gegen jede seitliche Verschiebung gesichert ist. Damit aber die Patrone in diese scheibenförmige Aussparung an der Stirnseite des Verschlusses hinein kann, muss die Ausziehklaue ausgeschwenkt werden und anschliessend eingeschwenkt werden, damit sie in die Ausziehnut der Patrone hineinragt.It is common to provide a disc-shaped recess on the front side of the breech, into which the rear end of the cartridge protrudes when it is inserted into the weapon barrel, as a result of which the cartridge is secured against any lateral displacement. However, so that the cartridge can enter this disc-shaped recess on the front side of the closure, the pull-out claw must be swung out and then swiveled in so that it projects into the pull-out groove of the cartridge.

Die Aufgabe, welche mit der vorliegenden Erfindung gelöst werden soll, besteht in der Schaffung einer radialen Sicherung der Patrone, wenn sie durch den Verschluss in das Waffenrohr hineingeschoben wird, ohne dass die Ausziehklaue verschwenkbar ausgebildet werden muss, dabei sollen, soweit als möglich, die Teile der Sicherheitsvorrichtung für die Zündverzögerung verwendet werden.The object which is to be achieved with the present invention is to provide a radial securing of the cartridge when it is pushed into the weapon barrel through the breech, without the pull-out claw having to be designed to be pivotable, while, as far as possible, the Parts of the safety device are used for the ignition delay.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass der Taststift einen axial hervorstehenden Sicherungsnocken aufweist, der seitlich am Rande des Patronenhülsen-Bodens anliegt, um die Patrone gegen ein seitliches Herausgleiten aus der Ausziehklaue zu sichern und dass am Waffengehäuse eine Steuerkurve befestigt ist, zum Zurückschieben des Taststiftes beim Zuführen der Patrone vor den Waffenverschluss.According to the invention, this object is achieved in that the stylus has an axially protruding locking cam, which rests laterally on the edge of the cartridge case base in order to secure the cartridge against sliding out laterally from the pull-out claw and in that a control cam is attached to the weapon housing is to push the stylus back when feeding the cartridge in front of the weapon breech.

Gemäss Fig.1 und 2 ist in einem Waffengehäuse 10 ein Rotor 11 mit Hilfe eines Kugellagers 13 drehbar gelagert. In diesem Rotor 11 sind mittels Bajonettverschlüssen sechs Waffenrohre 12 befestigt, von denen in Fig.2 nur ein Waffenrohr 12 sichtbar ist. Jedem Waffenrohr 12 ist ein Verschluss 14 zugeordnet. Jeder Verschluss 14 ist im Rotor 11 in Längsführungen 28 verschiebbar gelagert. Diese sechs Verschlüsse 14 sind in Fig.1 in Ansicht von vorne gezeigt. Gemäss Fig.1 werden Patronen 17 mit Hilfe einer endlosen Becherkette 15 der Waffe 9 zugeführt, welche um ein Sternrad 16 geschlungen ist. Die in den einzelnen Bechern 18 der Becherkette 15 befindlichen Patronen 17 werden mit Hilfe eines Sternrades 19 aus der Becherkette 15 ausgekämmt und vor den Verschluss 14a der Waffe 9 bewegt, bis die Patronenachse mit der Waffenrohrachse zusammenfällt (Fig.2). Der Boden 20 der Patrone 17 kommt dabei auf die Stirnfläche 21 des Verschlusses 14 zu liegen. Wenn sich der Verschluss 14a (Fig.1) in seine vorderste Stellung bewegt, schiebt er die Patrone 17 in die Ladekammer oder ins Patronenlager 22 des Waffenrohres 12. Diese Verschiebung des Verschlusses 14 wird durch die Drehung des Rotors 11 in Richtung des Pfeiles E bewirkt. Sobald die Patrone 17 abgefeuert worden ist, wird die leere Hülse 23 durch den Verschluss 14 wieder aus dem Patronenlager 22 des Waffenrohres 12 herausgezogen und durch ein weiteres Sternrad 24 (Fig.1) aus der Waffe 9 ausgeworfen, wobei sich das weitere Sternrad 24 in Richtung des Pfeiles F dreht. Der Aufbau einer solchen Waffe 9 mit mehreren Waffenrohren 12 und die Wirkungsweise werden als bekannt vorausgesetzt und hier nur soweit beschrieben, als sie für das Veständnis der vorliegenden Erfindung erforderlich sind.1 and 2, a rotor 11 is rotatably mounted in a weapon housing 10 with the aid of a ball bearing 13. In this rotor 11 six gun barrels 12 are fastened by means of bayonet locks, of which only one gun barrel 12 is visible in FIG. A closure 14 is assigned to each weapon barrel 12. Each closure 14 is slidably supported in the rotor 11 in longitudinal guides 28. These six closures 14 are shown in a view from the front in FIG. 1, cartridges 17 are supplied to the weapon 9 with the aid of an endless cup chain 15, which is wound around a star wheel 16. The cartridges 17 located in the individual cups 18 of the cup chain 15 are combed out of the cup chain 15 with the aid of a star wheel 19 and moved in front of the breech 14a of the weapon 9 until the cartridge axis coincides with the weapon barrel axis (FIG. 2). The bottom 20 of the cartridge 17 comes on End surface 21 of the closure 14 to lie. When the breech 14a (FIG. 1) moves to its foremost position, it pushes the cartridge 17 into the loading chamber or into the cartridge chamber 22 of the weapon barrel 12. This displacement of the breech 14 is brought about by the rotation of the rotor 11 in the direction of the arrow E. . As soon as the cartridge 17 has been fired, the empty sleeve 23 is pulled out of the cartridge chamber 22 of the weapon barrel 12 again by the breech 14 and ejected from the weapon 9 by a further star wheel 24 (FIG. 1), the further star wheel 24 in Direction of arrow F rotates. The structure of such a weapon 9 with several weapon tubes 12 and the mode of operation are assumed to be known and are only described here to the extent that they are necessary for the understanding of the present invention.

Gemäss Fig.2 und 5 ist an der Stirnfläche 21 des Verschlusses 14 eine Ausziehkralle 30 vorhanden, welche in eine Ausziehnut 25 der Patronenhülse 23 hineinragt. Damit die Patrone 17 beim Einschieben ins Waffenrohr nicht aus der Ausziehkralle 30 herausfallen kann, ist diagonal gegenüber der Ausziehkralle 30 ein Sicherungsnocken 26 an einem Taststift 27 angebracht. Damit die Patrone 17 in die Ausziehkralle 30 eingeschoben werden kann, muss der Taststift 27 mit dem Sicherungsnocken 26 zurückgezogen werden, wie weiter unten noch beschrieben. Gemäss Fig.5 wird die Patrone 17 in Richtung des Pfeiles Z zugeführt und die leere Patronenhülse 23 wird in Richtung des Pfeiles W weggeführt und dies ist nur möglich, wenn der Taststift 27 mit dem Nocken 26 soweit zurückgezogen wurde, dass der Hülsenboden 20 auf der Stirnfläche 21 des Verschlusses 14 gleiten kann.According to FIGS. 2 and 5, a pull-out claw 30 is present on the end face 21 of the closure 14, which protrudes into an pull-out groove 25 of the cartridge case 23. So that the cartridge 17 cannot fall out of the pull-out claw 30 when inserted into the weapon barrel, a locking cam 26 is attached diagonally to the pull-out claw 30 on a stylus 27. So that the cartridge 17 can be inserted into the pull-out claw 30, the stylus 27 with the safety cam 26 must be withdrawn, as will be described further below. According to Figure 5, the cartridge 17 is fed in the direction of arrow Z and the empty cartridge case 23 is moved away in the direction of arrow W and this is only possible if the stylus 27 has been retracted with the cam 26 so far that the sleeve bottom 20 on the End face 21 of the closure 14 can slide.

Gemäss Fig.2 setzt sich der Verschluss 14 aus einem Verschlusskopf 31, einem Verschlusskopfhalter 32 und einem Verschlussträger 33 zusammen. Der Verschlusskopf 31 ist auf den Verschlusskopfhalten 32 über ein Steilgewinde 34 aufgeschraubt und der Verschlusskopfhalter 32 ist über einen Hebel 35 mit dem Verschlussträger 33 in nicht näher dargestellter Weise gekoppelt. Eine Rolle 36, welche auf dem Verschlussträger 33 drehbar gelagert ist, ragt in eine Steuernut 37 des Waffengehäuses 10 hinein. Wenn sich der Rotor 11 im Waffengehäuse 10 dreht, dann wird durch die Steuernut 37 der Verschluss 14 soweit zurückgezogen, dass die leere Patronenhülse 23 ausgeworfen und eine weitere Patrone 17 zugeführt werden kann. Dabei dreht sich der Verschlusskopf 31 auf dem Verschlusskopfhalter 32 und verschiebt sich gleichzeitig aus der Stellung gemäss Fig.2 in die Stellung gemäss Fig.3. Der Taststift 27 ist im Verschlusskopfhalter 32 verschiebbar geführt, und von einer Feder 38 belastet. Dieser Taststift 27 ist durch die Patrone 17 gemäss Fig.2 in seiner hintersten Stellung gehalten und bewegt sich gemäss Fig.3 bei der Verschiebung des Verschlusskopfes 31 nach vorne, so dass der Sicherungsnocken 26 immer um den selben Betrag über die Stirnfläche 21 des Verschlusses 14 hervorsteht. Im Verschlussträger 33 ist ein Zündstift 39 verschiebbar gelagert und von einer Feder 40 belastet.According to FIG. 2, the closure 14 is composed of a closure head 31, a closure head holder 32 and a closure carrier 33. The closure head 31 is screwed onto the locking head holder 32 via a steep thread 34 and the locking head holder 32 is coupled to the locking carrier 33 in a manner not shown via a lever 35. A roller 36, which is rotatably mounted on the breech block 33, projects into a control groove 37 of the weapon housing 10. When the rotor 11 rotates in the weapon housing 10, the breech 14 is retracted by the control groove 37 to such an extent that the empty cartridge case 23 can be ejected and a further cartridge 17 can be fed. The locking head 31 rotates on the locking head holder 32 and at the same time shifts from the position shown in FIG. 2 to the position shown in FIG. 3. The stylus 27 is slidably guided in the closure head holder 32 and loaded by a spring 38. This stylus 27 is held in its rearmost position by the cartridge 17 according to FIG. 2 and moves forward according to FIG. 3 when the locking head 31 is displaced, so that the locking cam 26 always has the same amount over the end face 21 of the locking mechanism 14 protrudes. An ignition pin 39 is slidably mounted in the closure carrier 33 and loaded by a spring 40.

Gemäss Fig.6-10 ist eine Steuerschiene 41 vorgesehen, um den Taststift 27 soweit zurückzuschieben, dass der Sicherungsnocken 26 nicht mehr über die Stirnfläche 21 hervorsteht, damit die leere Patronenhülse 23 ausgeworfen und die nächste Patrone 17 zugeführt werden kann. Diese Steuerschiene 41 ist am Waffengehäuse 10 befestigt wie aus Fig.1 ersichtlich ist. Diese Steuerkurve 41 weist an ihrem einen Ende eine steilere Steuerfläche 42 und an ihrem anderen Ende eine flachere Steuerfläche 43 auf. Gegen die Steuerflächen 42 und 43 stösst ein Hebel 44, der schwenkbar am Taststift 27 angelenkt ist (siehe Fig.2 und 3).According to FIGS. 6-10, a control rail 41 is provided in order to push the stylus 27 back so far that the safety cam 26 no longer protrudes over the end face 21, so that the empty cartridge case 23 can be ejected and the next cartridge 17 can be fed. This control rail 41 is fastened to the weapon housing 10, as can be seen from FIG. This control curve 41 has a steeper control surface 42 at one end and a flatter control surface 43 at its other end. A lever 44 abuts against the control surfaces 42 and 43 and is pivotably articulated on the stylus 27 (see FIGS. 2 and 3).

Die Wirkungsweise der beschriebenen Vorrichtung ist wie folgt:
Gemäss Fig.1 dreht sich bei einem Seriefeuer der Rotor 11 in Richtung des Pfeiles E im Waffengehäuse 10, und dabei drehen sich auch die Waffenrohre 12 und die Verschlüsse 14a-14f. Da die Verschlüsse 14a-14f gemäss Fig.2 mit ihrer Rolle 36 in der Steuernut 37 geführt sind, bewegt sich jeder Verschluss 14 bei einer Umdrehung des Rotors 11 aus seiner vordersten in seine hinterste Stellung und wieder in seine Ausgangsstellung nach vorne. Diese Verschiebung der Verschlüsse 14 ist in Fig.11 dargestellt. Bei einer vollen Drehung des Rotors um 360° befindet sich der Verschluss zuerst bei 0° in seiner hintersten Stellung und bleibt während der Drehung um 30° in dieser hintersten Stellung. Während der Drehung um weitere 120° bewegt sich der Verschluss 14 nach vorne und bleibt bei der Drehung um weitere 60° in seiner vordersten Stellung. Bei der Drehung um weitere 120° bewegt sich der Verschluss 14 wieder zurück und bleibt bei der Drehung um 60°, d.h. von Winkel 330° bis 30° wieder in seiner hintersten Stellung. Solange sich der Verschluss 14 in seiner hintersten Stellung befindet, soll der Taststift 27 mit dem Sicherungsnocken 26 soweit zurückgestossen werden, dass die leere Patronenhülse 23 ausgestossen werden kann und die nächste Patrone 17 zugeführt werden kann. Gemäss Fig.1 und 11 stösst somit der Taststift 27 mit seinem schwenkbaren Hebel 44 (Fig.2) gegen die steilere Steuerfläche 42 der Steuerschiene 41 und wird solange gegen die Kraft der Feder 38 zurückgeschoben, bis der Verschluss 14 wieder anfängt sich nach vorne zu bewegen und der Taststift 27 mit seinem schwenkbaren Hebel 44 auf der flacheren Steuerfläche 43 wieder von der Steuerschiene 41 abgleitet. Wie aus Fig.2 ersichtlich ist, wird der Taststift 27 kurz vor dem Auswerfen der leeren Patronenhülse 23 zurückgestossen und kurz nach dem Einschieben der nächsten Patrone 17 vor den Verschluss 14 wieder freigegeben.The operation of the described device is as follows:
1, in the case of a series fire, the rotor 11 rotates in the direction of the arrow E in the weapon housing 10, and the weapon tubes 12 and the breeches 14a-14f also rotate in the process. Since the closures 14a-14f are guided with their roller 36 in the control groove 37 according to FIG. 2, each closure 14 moves with one revolution of the rotor 11 from its foremost position to its rearmost position and back to its starting position. This displacement of the closures 14 is shown in Fig.11. With a full rotation of the rotor through 360 °, the closure is first at 0 ° in its rearmost position and remains in this rearmost position during rotation by 30 °. During the rotation through a further 120 °, the closure 14 moves forward and remains in its foremost position when the rotation through a further 60 °. When rotated through a further 120 °, the closure 14 moves back again and remains in its rearmost position when rotated through 60 °, ie from an angle of 330 ° to 30 °. As long as the closure 14 is in its rearmost position, the stylus 27 with the locking cam 26 should be pushed back so far that the empty cartridge case 23 can be ejected and the next cartridge 17 can be fed. According to FIGS. 1 and 11, the feeler pin 27, with its pivotable lever 44 (FIG. 2), pushes against the steeper control surface 42 of the control rail 41 and is pushed back against the force of the spring 38 until the closure 14 starts again towards the front move and the stylus 27 with its pivotable lever 44 on the flatter control surface 43 slides again from the control rail 41. As can be seen from FIG. 2, the stylus 27 is pushed back shortly before the empty cartridge sleeve 23 is ejected and released again shortly after the next cartridge 17 has been inserted in front of the closure 14.
