Description

In der DE 10 2006 022 622 A1 wird eine lineare Zuführung der Munition in ein Waffenrohr bzw. Patronenlager beschrieben, welche eine zur Funktionssteuerung verwendete Steuerkulisse in der horizontalen Ebene parallel zum Weg eines geradlinig zu führenden Verschlusses der Verschlusswaffe aufweist. Diese wirkt funktional mit einer so genannten gleichfalls in der horizontalen Ebene liegenden Antriebskulisse zum Führen eines mit dem Verschluss verbundenen Mittels zusammen. Die Antriebskulisse ist in einem bewegbaren Schieber integriert, welcher seinerseits durch einen universell gestaltbaren Antrieb verstellt wird. Für eine Verriegelung des Verschlusses ist des Weiteren eine Verriegelungskulisse vorgesehen, die bevorzugt zusammen mit der Antriebskulisse in dem bewegbaren Schieber eingebunden ist. In diese Verriegelungskulisse kann ein Bolzen eines vorzugsweise waffenseitig angeordneten Verriegelungsringes eingreifen. Dieser Bolzen bewegt seinerseits dann den Verriegelungsring. Innerhalb der miteinander wirkenden Steuerkulisse und der Antriebskulisse wird ein Pleuel oder dergleichen durch die Kulissen und den Schieber entlang dieser Kulissen zwangsgeführt. Mit diesem Pleuel wird der Verschluss hin und her bewegt.In the DE 10 2006 022 622 A1 a linear supply of the ammunition is described in a gun barrel or cartridge chamber having a control link used for function control in the horizontal plane parallel to the path of a straight-to-leading closure of the closure weapon. This functionally cooperates with a so-called also in the horizontal plane drive link for guiding a connected to the closure means. The drive link is integrated in a movable slide, which in turn is adjusted by a universal design drive. For a locking of the closure further comprises a locking link is provided, which is preferably integrated together with the drive link in the movable slide. In this locking link can engage a bolt preferably a weapon side arranged locking ring. This bolt in turn then moves the locking ring. Within the co-acting control link and the drive link a connecting rod or the like is forcibly guided through the scenes and the slide along these scenes. With this connecting rod, the shutter is moved back and forth.

Die US 3 889 572 beschreibt eine Funktionssteuerung gemäß Oberbegriff des unabhängigen Anspruchs 1.The US 3,889,572 describes a function control according to the preamble of independent claim 1.

Eine Nutzung für eine Trommelwaffe ist weder angedacht noch damit möglich.A use for a drum weapon is neither planned nor possible.

Hier stellt sich die Erfindung die Aufgabe, eine Funktionssteuerung für eine Trommelwaffe aufzuzeigen, mit der ein einfaches Zuführen der Munition in ein Waffenrohr erreicht werden kann.Here, the invention has the object to show a function control for a drum weapon, with a simple feeding of the ammunition can be achieved in a gun barrel.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgeführt.The object is achieved by the features of claim 1. Advantageous embodiments are listed in the subclaims.

Der Erfindung liegt die Idee zugrunde, die Funktionssteuerung ebenfalls mittels Kulissen und in diesen geführten Pleuels zu realisieren. Die Funktionssteuerung selbst umfasst dabei das Zuführen einer Munition in die Trommel bzw. das jeweilige Patronenlager und die Schaltung einer Trommel zur Verstellung selbiger. Beide Pleuel werden durch einen gemeinsamen Schieber betätigt bzw. in den Kulissen des Schiebers geführt. In einer der Kulissen befindet sich somit der Pleuel, das mit einem Schaltschieber zusammenwirkt, in der anderen Kulisse wird der Pleuel des Zuführschiebers geführt. Der Schieber bzw. die darin eingebundenen Kulissen selbst sind vorzugsweise bzw. wenigstens in zwei Ebenen aufgeteilt, wobei die beiden Ebenen zueinander verstellbar (verschiebbar) sind. Eine weitere Aufteilung wäre möglich, wird jedoch als nicht notwendig angesehen.The invention is based on the idea to realize the function control also by means of scenes and in this guided connecting rod. The function control itself includes the feeding of an ammunition into the drum or the respective cartridge chamber and the circuit of a drum for adjusting selbiger. Both connecting rods are operated by a common slide or guided in the scenes of the slider. Located in one of the scenes Thus, the connecting rod, which interacts with a slide switch, in the other backdrop, the connecting rod of the feed is performed. The slide or the scenes integrated therein are preferably divided or at least in two levels, wherein the two levels are mutually adjustable (displaceable). A further division would be possible, but is not considered necessary.

Der Schaltschieber bzw. Nocken des Schaltschiebers der Trommel wird seinerseits in einer Schaltkurve geführt, die umfangsseitig auf der Trommel eingebunden ist. In Weiterführung der Erfindung kann durch Aufteilung dieser Schaltkurve die Trommellänge auf die maximale Patronenlänge reduziert bzw. minimiert werden. Das macht diesen Bereich kleiner bauend.The slide switch or cam of the slide switch of the drum is in turn guided in a switching curve, which is peripherally integrated on the drum. In continuation of the invention can be reduced or minimized by dividing this switching curve, the drum length to the maximum cartridge length. That makes this area smaller.

In einer besonderen Ausführung ist die Trommel in einem geschlossenen Gehäuse untergebracht. In diesem Fall wird die Munition von vorne in das Patronenlager der Trommel eingebracht.In a particular embodiment, the drum is housed in a closed housing. In this case, the ammunition is introduced from the front into the chamber of the drum.

In Fig. 1 erkennbar sind die für die Erläuterung wesentlichen Teile einer sonst nicht detaillierter dargestellten Waffe 1 mit Waffenlauf 2 aufgezeigt.In Fig. 1 recognizable are essential for the explanation of parts of a weapon not otherwise shown in detail 1 with gun barrel 2 shown.

Die Waffe 1 umfasst eine Trommel 3, die in dieser Ausführung sich dadurch auszeichnet, dass sie ein geschlossenes Gehäuse 4 besitzt. In diesem integriert sind vorzugsweise vier Patronenlager 5 zur Aufnahme einer von vorne (P) zuführbaren Munition (21, Fig. 2). Hinten abgeschlossen wird die Trommel 3 durch einen vorzugsweise gehäuseeigenen Deckel bzw. Stoßboden 6.The weapon 1 comprises a drum 3, which is characterized in this embodiment in that it has a closed housing 4. Four cartridge chambers 5 for receiving a munition (21), which can be supplied from the front (P), are preferably integrated in the latter. Fig. 2 ). Behind the drum 3 is completed by a preferably housing own lid or shock bottom. 6

Die Trommel 3 beisitzt umfangsseitig eine Trommelschaltung in Form einer Führungskurve 20 und wird durch einen Schaltschieber 7 gedreht. Das Besondere in der in diesem Ausführungsbeispiel bevorzugten Variante ist, dass die Trommelschaltung bzw. die Führungskurve 20 geteilt ist. Dazu weist der Schaltschieber 7 zwei Nocken 8, 9 auf, wobei der hintere Nocken 8 höhenbeweglich, vorzugsweise federnd gelagert ist. Mit dem Schaltschieber 7 verbunden ist ein Pleuel 10.The drum 3 beisitzt circumferentially a drum circuit in the form of a guide cam 20 and is rotated by a slide switch 7. The special feature in the preferred embodiment in this embodiment is that the drum circuit or the guide curve 20 is divided. For this purpose, the slide switch 7 two cams 8, 9, wherein the rear cam 8 is mounted vertically movable, preferably resiliently. Connected to the slide switch 7 is a connecting rod 10th

Ist die Führungskurve 20 hingegen ungeteilt, benötigt der Schaltschieber 7 seinerseits nur einen Nocken 8.If, however, the guide cam 20 is undivided, the slide switch 7 in turn requires only one cam 8.

Mit diesen Elementen funktional über den Pleuel 10 ist ein weiter vorne am Waffenlauf 2 eingebundener und in zwei Ebenen geteilter Schieber 11 mit zwei oberen Steuerkurven 11 a, 11 b und zwei unteren Steuerkurven 11 c, 11 d verbunden, die obere Steuerkurve 11 a und die untere Steuerkurve 11 c mit dem Pleuel 10 des Schaltschiebers 7 und die Steuerkurven 11 b, 11 d mit einem Pleuel 13 eines Zuführschiebers 14 (Fig. 2) für die Munition 21 zusammen arbeiten. Die Steuerkurven 11a und 11 c sowie 11 b und 11 d haben eine, mit einem Hockeyschläger vergleichbare Kurvenführung und ergänzen sich funktional. Die obere Ebene des Schiebers 11 ist bewegbar. Eine Draufsichtdarstellung dazu ist der Fig. 2 entnehmbar.With these elements functionally via the connecting rod 10 is a further front of the gun barrel 2 integrated and divided into two levels slide 11 with two upper cams 11 a, 11 b and two lower cams 11 c, 11 d connected to the upper cam 11 a and the lower control cam 11 c with the connecting rod 10 of the slide valve 7 and the control cams 11 b, 11 d with a connecting rod 13 of a feed slide 14 (FIG. Fig. 2 ) work together for the ammunition 21. The cams 11 a and 11 c and 11 b and 11 d have a comparable with a hockey stick curve guide and complement each other functionally. The upper level of the slider 11 is movable. A plan view of this is the Fig. 2 removable.

Insbesondere anhand der Fig. 3 soll der Ablauf des Ladens bzw. Zuführens der Munition 21 der Waffe 1 veranschaulicht werden. Wenngleich die Waffe 1 hier als eigen angetriebene Waffe (Gasdruck) dargestellt ist, kann auch eine andere Antriebsart (fremd angetrieben) verwendet werden.In particular, based on the Fig. 3 the process of loading or supplying the ammunition 21 of the weapon 1 should be illustrated. Although the weapon 1 is shown here as a self-propelled weapon (gas pressure), another type of drive (driven externally) can also be used.

Durch den Antrieb, hier ein Gaskolben 22 (alternativ auch Fremdantrieb möglich), wird die sich vorher in seiner Ausgangsstellung (Fig. 3a) befindliche obere Ebene des Schiebers 11 zur unteren Ebene des Schiebers 11 verstellt (Fig. 3b). Mit dieser Verstellung fährt die Steuerkurve 11a am Pleuel 10 entlang, während der Pleuel 10 selber stehen bleibt. Der Pleuel 13 hingegen wird durch die Steuerkurve 11 b bewegt und damit auch der Zuführschieber 14. In etwa zeitgleich erreichen der Pleuel 10 als auch der Pleuel 13 den Umkehrpunkt U in ihren oberen Steuerkurven 11a, 11 b (Fig. 3c), die Munition 21 ist zugeführt. Nunmehr wirken die unteren, feststehenden Steuerkurven 11c, 11d. Der Zuführschieber 14 bleibt stehen, da der Pleuel 13 abgelegt und nicht weiter bewegt wird, der Schaltschieber 7 hingegen wird durch den in der Steuerkurve 11a weiter verstellten Pleuel 10 bewegt. Mit Einnahme des gemeinsamen Endpunktes E in der unteren als auch oberen Ebene, beide Pleuels 10, 13 haben innerhalb ihrer Schaltkurven 11a, 11 c, bzw. 11 b, 11 d ihre Entstellung eingenommen, fährt die obere Ebene des Schieber 11 wieder zurück (Fig. 3d), der Schaltschieber 7 führt über die Nocken 8, 9 die Trommelbewegung bzw. Trommelschaltung beispielsweise um 45° aus (bei vier Patronenlager 5) (Fig. 3e). Erreicht der Pleuel 10 das Ende seiner unteren Steuerkurve 11 c und den Umkehrpunkt U in seiner oberen Steuerkurve 11a, befindet sich das System in der Schussposition S. Danach läuft der Schieber 11 zurück, nimmt über den Pleuel 13 den Zuführschieber 14 in die so genannte Ausgangsstellung und damit in die Zündstellung mit (Fig. 3f).By the drive, here a gas piston 22 (alternatively also third-party drive possible), which is previously in its starting position ( Fig. 3a ) located upper level of the slider 11 to the lower level of the slide 11 ( Fig. 3b ). With this adjustment, the control cam 11a moves along the connecting rod 10, while the connecting rod 10 itself stops. The connecting rod 13, however, is moved by the control cam 11 b and thus also the Zuführschieber 14. In about the same time reach the connecting rod 10 and the connecting rod 13, the reversal point U in their upper cams 11 a, 11 b ( Fig. 3c ), the ammunition 21 is supplied. Now act the lower, fixed cams 11c, 11d. The feed slide 14 stops because the connecting rod 13 is stored and not moved further, the slide switch 7, however, is moved by the in the control cam 11 a further adjusted connecting rod 10. With taking the common end point E in the lower and upper level, both cones 10, 13 have taken their distortion within their switching curves 11 a, 11 c, and 11 b, 11 d, the upper level of the slide 11 moves back ( Fig. 3d ), the slide switch 7 performs on the cams 8, 9, the drum movement or drum circuit, for example, by 45 ° (four cartridge bearing 5) ( Fig. 3e ). Reached the connecting rod 10, the end of its lower cam 11 c and the reversal point U in its upper cam 11a, the system is in the firing position S. Thereafter, the slider 11 goes back, takes over the connecting rod 13, the feed slider 14 in the so-called starting position and thus in the ignition position with ( Fig. 3f ).

Der Ablauf wiederholt sich zum Neuladen und Auslösen.The process repeats to reload and trigger.

In der bevorzugten Ausführung ist die Trommelschaltung 20 als geteilte Trommelkurve vorgesehen. Dies ermöglicht die Verkürzung der Trommel 3 auf die Patronenlänge. Näher dargestellt ist diese Ausführungsvariante in Fig. 4, aus dieser sind beide Versionen erkennbar.In the preferred embodiment, the drum circuit 20 is provided as a split drum cam. This allows the shortening of the drum 3 on the cartridge length. This embodiment is shown in more detail in FIG Fig. 4 , from this both versions are recognizable.

Der hintere federnde Nocken 8 befindet sich in der Ausgangsstellung (keine Patrone 21 zugeführt) im Eingriff mit der hinteren Führungskurve 20.1, der vordere Nocken 9 derzeit noch nicht. Durch Bewegen des Schaltschiebers 7 (mittels Pleuel 10) wird der Nocken 8 entlang dieser Führungskurve 20.1 geführt. Noch bevor der Nocken 8 aus dieser austritt, kommt der zweite Nocken 9 in Eingriff mit der vorderen Führungskurve 20.2. Die Bewegung des Schaltschiebers 8 wird nun durch die Gestaltung der vorderen Führungskurve 20.2 definiert. In diese ist zur Totpunktverlagerung und Vermeidung von Störungen eine so genannte Handschaltkurve H in Form einer Schräge eingebunden, wodurch kein Totpunkt verursacht werden kann. Damit der hintere Nocken 8 nicht aus seiner Führungskurve 20.1 bei der Bewegungsumkehrung ausbrechen kann, ist eine seitliche Erhöhung in der Führungskurve 20.1 vorgesehen.The rear resilient cam 8 is in the starting position (no cartridge 21 supplied) in engagement with the rear guide cam 20.1, the front cam 9 is not yet. By moving the slide switch 7 (by connecting rod 10), the cam 8 is guided along this guide curve 20.1. Even before the cam 8 emerges from this, the second cam 9 comes into engagement with the front guide curve 20.2. The movement of the slide valve 8 is now defined by the design of the front guide curve 20.2. In this is for Totpunktverlagerung and avoiding disturbances a so-called manual shift curve H in the form of a slope involved, whereby no dead center can be caused. So that the rear cam 8 is not out of its guide curve 20.1 in the reversal of movement can break out, a lateral increase in the guide curve 20.1 is provided.

Vor Austritt des Nockens 9 aus der vorderen Führungskurve 20.2 greift wieder der hintere Nocken 8 in das Geschehen, d.h., in die hintere Führungskurve 20.1 ein und nimmt zusammen mit dem Schaltschieber 7 die Ausgangsstellung 0° - Schussauslösung S - ein. Ist ein Dauerfeuer eingestellt, liegt die Ausgangsstellung leicht differenziert gegenüber der ursprünglichen Ausgangsstellung weiter vorne (Fig. 4a). Dieser Effekt kann ausgenutzt werden, um die laufenden Massen dem Rückstoß des nächstfolgenden Schusses entgegenzustellen.Before exit of the cam 9 from the front guide curve 20.2 again engages the rear cam 8 in the action, ie, in the rear guide curve 20.1 and takes together with the slide switch 7, the starting position 0 ° - shot release S - a. If a continuous fire is set, the initial position is slightly differentiated from the original starting position further forward ( Fig. 4a ). This effect can be exploited to counter the current masses to the recoil of the next shot.

Mit dem Weg des Schiebers 7 nach hinten wird die Trommel 3 somit um 45° gedreht, mit der Vorwärtsbewegung des Schiebers 7 erfolgt die Drehung der Trommel 3 um die restlichen 45°. Diese Winkelgrade der notwendigen Drehung der Trommel 3 bestimmen sich aus der Anzahl der vorhandenen Patronenlagern 5 in einer Trommel, so dass bei einer anderen Anzahl von Patronenlagern 5 als die beschriebenen vier, die Kurvengestaltung der geteilten Führungskurve 20 anzupassen wäre.With the path of the slider 7 to the rear, the drum 3 is thus rotated by 45 °, with the forward movement of the slider 7, the rotation of the drum 3 is carried by the remaining 45 °. These degrees of rotation necessary rotation of the drum 3 are determined by the number of existing cartridge bearings 5 in a drum, so that would be in a different number of cartridge bearings 5 than the four described, the curve shape of the split guide curve 20 would adjust.

Die Summe beider Führungskurven 20.1 und 20.2 zu einer gemeinsamen Trommelkurve 20 ergäbe hingegen die einfachste Variante. Dabei würde sich die vordere Führungskurve 20.2 an die hintere Führungskurve 20.1 übergangslos anschließen und nur der eine Nocken 8 die gemeinsame Führungskurve 20 abfahren. Auf den Nocken 9 kann dann verzichtet werden.The sum of both guide curves 20.1 and 20.2 to a common drum cam 20, however, would give the simplest variant. In this case, the front guide curve 20.2 would connect seamlessly to the rear guide curve 20.1 and only the one cam 8 would start the common guide curve 20. On the cam 9 can then be dispensed with.

In Fig. 5 ist eine Schnittdarstellung im Schnitt A-A aus Fig. 1. dargestellt, die in Fig. 6 teilweise vergrößert dargestellt ist und vorteilhafte Anbindungen an der Waffe 1 zeigen. Mit 15 ist eine Lagerung des Waffenrücklaufes gekennzeichnet, die durch die Schaftintegration der Führungsschiene eine sehr einfache aber effektive Lagerung bewirkt. Mit Z ist die Zuführposition, mit S die Schussposition und mit A die Auswurfposition bezeichnet. Ein Magazin 16 bevorratet die zuzuführende Munition 21. Diese Ausführung benötigt keine schrittweise Zuführung der Munition 21 in die Schussposition, jedoch kann alternativ zwischen der Patronenzuführung und dem Magazinantrieb gleichfalls eine Steuerkurve eingebunden werden, durch die eine getaktete Zuführung realisiert werden kann.In Fig. 5 is a sectional view in section AA Fig. 1 , represented in Fig. 6 is shown partially enlarged and show advantageous connections to the weapon 1. With 15 storage of the weapon return is characterized, which causes a very simple but effective storage by the shaft integration of the guide rail. Z is the feed position, S is the shot position and A is the ejection position. A magazine 16 stores the ammunition 21 to be supplied. This embodiment does not require a gradual feeding of the ammunition 21 into the firing position, but alternatively a control cam can be integrated between the cartridge feed and the magazine drive, by means of which a clocked feed can be realized.

Fig. 7 zeigt in einer bevorzugten Ausführung die Einbindung eines Wendelmagazins 16', welches gegenläufig zur Trommel 3 wirkend angebracht einen Drehmomentausgleich bewirkt. Fig. 7 shows in a preferred embodiment, the inclusion of a spiral magazine 16 ', which acts in opposite directions to the drum 3 causes a torque balance.
