Abstract

The invention relates to a quick stop mechanism (20) for a weapon drive (14) of a weapon with ammunition (5) fed to a weapon barrel (4) of the weapon (1). The invention is characterized in that the quick stop mechanism functionally interacts with the drive (14) and with a returning weapon part (2), the quick stop mechanism (20) being engaged when the breach advances, in such a manner that the quick stop mechanism (20) lies on the opposite side in the trajectory of the drive (14). A means (21) integrated into the returning weapon part (2) travels onto a phase (22.1) on the quick stop mechanism (20) when the shot is triggered, thereby pushing the quick stop mechanism (20) out of position in such a manner that the drive (14) can travel freely past the quick stop mechanism (20). In the event of a firing failure, the quick stop mechanism (20) stops the drive (14) at least temporarily.

Description

BESCHREIBUNG DESCRIPTION
Schnellstopp für einen Antrieb einer Waffe mit vorzugsweise linearerQuick stop for a drive of a weapon with preferably linear
Munitionszuführungammunition feed
Aus dem Stand der Technik sind verschiedene Antriebe wie Fremd- oder Eigenantriebe für Waffensysteme bekannt. Bei Fremdantrieben werden häufig elektrische Antriebe vorgesehen, welche dann beispielsweise eine Kette antreiben. Ein bekannter Kettenantrieb wird in der unter dem Namen Bushmaster oder auch Chain Gun bekannten Maschinenkanone angewandt. Hierbei werden notwendige Stillstandszeiten zum Verschließen des Verschlusses, für das Schussauslösen, für das Öffnen des Verschlusses sowie das Vorlegen einer Patrone vor den Verschluss durch eine umlaufende, von einem Motor angetriebene Kette realisiert (http://de.wikipedia.org/wiki/M242 Bushmaster). Der Verschluss mit der davor liegenden Munition bzw. Patrone wird dabei dem Patronenlager linear zugeführt.From the prior art, various drives such as foreign or self-propelled weapon systems are known. In third-party drives electric drives are often provided, which then drive, for example, a chain. A well-known chain drive is used in the known under the name Bushmaster or Chain Gun automatic cannon. Here necessary downtime for closing the shutter, for firing the shot, for opening the shutter and the presentation of a cartridge before the closure by a rotating, driven by a motor chain realized (http://de.wikipedia.org/wiki/M242 Bushmaster). The closure with the preceding ammunition or cartridge is thereby fed linearly to the cartridge chamber.
In der nicht vorveröffentlichten DE 10 2006 022 622.4 wird ein Waffensystem beschrieben, welches 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. Angedacht ist hier ein Antrieb des Pleuels beispielsweise mittels einer umlaufenden Kette. Weitere Detailfragen diesbezüglich werden hier nicht behandelt.In the non-prepublished DE 10 2006 022 622.4 a weapons system is described, which has a control link used for the 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. An idea here is a drive of the connecting rod, for example by means of a rotating chain. Further detailed questions in this regard are not dealt with here.
Für die sichere Funktion einer Waffe ist es wichtig, das Zünden eines Zündversagers insbesondere in der Entriegelungs- bzw. Öffnungsphase des Waffenverschlusses zu verhindern.For the safe operation of a weapon, it is important to prevent the ignition of a Zündversagers especially in the unlocking or opening phase of the weapon lock.
Hier stellt sich die Erfindung die Aufgabe, eine Vorrichtung aufzuzeigen, die ein verspätetes Zünden der Munition zulässt, einen Zündversager jedoch sicher aus der Waffe bringt. Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgelistet.Here, the invention has the object to show a device that allows late ignition of the ammunition, however, brings a Zündversager safely out of the weapon. The object is achieved by the features of claim 1. Advantageous embodiments are listed in the subclaims.
Der Erfindung liegt die Idee zugrunde, einen Schnellstopp in den Antrieb einzubinden, wodurch ein zu frühes Entriegeln bzw. Öffnen des Verschlusses vermieden wird. Dieser Schnellstopp dient somit dazu, dass beim Zündversager ein Entriegeln des Verschlusses vorzeitig verhindert wird. Der Schnellstopp wird stetig eingelegt und im Falle eines ordnungsgemäßen Schusses ausgesteuert. Im Falle eines Zündversagers, wo bekanntlich der Rücklauf des Waffenrohreε fehlt, läuft ein Mittel, weiches mit dem Waffenrücklauf funktional verbunden ist, auf den Schnellstopp auf, die Antriebsbewegung wird gestoppt, das Entriegeln des Verschlusses unterbleibt zumindest für eine vorgebbare Zeit. Der Schnellstopp ist dabei so ausgeführt, dass er die Auflaufkraft aufnehmen kann und Materialbruch vermieden wird. Dies kann durch Einbindung einer Feder oder eines Puffers oder dergleichen in den Schnellstopp geschaffen werden, wodurch der Schnellstopp in Belastungsrichtung elastisch reagiert.The invention is based on the idea to include a quick stop in the drive, whereby too early unlocking or opening of the closure is avoided. This quick stop is thus used to prevent premature release of the lock at Zündausager. The quick stop is constantly inserted and controlled in case of a proper shot. In the case of a Zündversagers, where known the return of the Waffenrohreε is missing, runs a means that is soft with the weapon return functionally, on the quick stop, the drive movement is stopped, the unlocking of the closure is omitted at least for a predetermined time. The quick stop is designed so that it can absorb the accumulation force and material breakage is avoided. This can be created by incorporating a spring or a buffer or the like in the quick stop, whereby the quick stop in the loading direction reacts elastically.
Als Antrieb kann eine Kette vorgesehen werden. Alternativen sind getriebetechnische Lösungen, Zahnräder oder auch ein Rückstoßladerantrieb.As drive a chain can be provided. Alternatives are gearbox solutions, gears or a recoil loader drive.

In Fig. 1 ist schematisch dargestellt eine Waffe 1 mit den zur Erläuterung der Erfindung wesentlichen Details. Dargestellt sind ein Verschluss 2, ein Verschlussring 3 sowie angedeutet ein Waffenrohr 4. Vorzugsweise unterhalb des Weges, den der Verschluss 2 zur geradlinigen Zuführung einer Munition / Patrone 5 innerhalb der Waffe 1 zurücklegt, ist eine Steuerkulisse 6 einer Funktionssteuerung 7 angeordnet, die in einer Draufsicht in Fig. 2 aufgezeigt ist. Die Steuerkulisse 6 besitzt eine mit einem großen S vergleichbare Form, wobei die mittige Führungszone der Kulisse 6 bis zu den leicht gekrümmten Kurvenenden gestreckt ist (I) und ist in einer Schiene 8 integriert. Mit dieser Steuerkurve 6 funktional wirksam ist eine Antriebskulisse 9 vorgesehen, welche zur Steuerkurve 6 verschiebbar ist. Die Wirkungsweise bzw. das Zusammenspiel beider wird in der DE 10 2006 022 622.4 ausführlich beschrieben, auf weiche hier Bezug genommen wird.In Fig. 1 is shown schematically a weapon 1 with the essential details for explaining the invention. Shown are a closure 2, a locking ring 3 and indicated a gun barrel 4. Preferably below the path, the cover 2 for straight feeding an ammunition / cartridge 5 travels within the weapon 1, a control link 6 a function control 7 is arranged in a Top view in Fig. 2 shown is. The control link 6 has a shape comparable to a large S, wherein the central guide zone of the link 6 is stretched to the slightly curved curve ends (I) and is integrated in a rail 8. Functionally effective with this control cam 6, a drive cam 9 is provided, which is displaceable to the control cam 6. The mode of action or the interaction of both is described in detail in DE 10 2006 022 622.4, to which reference is made here.
Zur hier aufgezeigten Funktionssteuerung 7 zugehörig wird eine Verriegelungskulisse 10 gesehen, die, wie die Antriebskurve S, vorzugsweise in einem gemeinsamen Schieber 11 integriert ist. Die Verriegelungskulisse 10 dient hierbei zum Verriegeln / Entriegeln des Verschlusses 2 im Gebrauch der Waffe 1. Für diese Funktion weist der Schieber 11 eine zur vertikalen Ebene vorzugsweise leicht angestellte Fläche auf, in der die VerriegelungskurveBelonging to the function control 7 shown here, a locking link 10 is seen, which, like the drive curve S, is preferably integrated in a common slide 11. The locking link 10 serves in this case for locking / unlocking the closure 2 in the use of the weapon 1. For this function, the slider 11 has a preferably slightly inclined surface to the vertical plane, in which the locking curve
10 eingebunden ist, damit ein am Verschlussring 3 angebrachter Bolzen (nicht näher dargestellt) in diese Kulisse 10 eingreifen kann. Andere Lösungen als die Kulisse 10 für das Ver- und Entriegeln des Verschlusses 2 sind jedoch auch möglich.10 is involved, so that a bolt attached to the locking ring 3 (not shown in detail) can engage in this backdrop 10. Other solutions than the gate 10 for locking and unlocking the shutter 2 are also possible.
Die erkennbare Zweiteilung der Schiene 8 stellt eine bevorzugte Variante der Schiene 8 dar, In der Zweiteilung wird ein so genanntes Rücklaufspiel R gebunden. Dieses Spiel R berücksichtigt den Rücklaufweg des Waffenrohres 4 mit Verschluss 2.The recognizable division of the rail 8 represents a preferred variant of the rail 8, in the division of a so-called backlash R is bound. This game R takes into account the return path of the gun barrel 4 with closure 2.
Ein Pleuel 12, welches mit dem Verschluss 2 konstruktiv verbunden ist, greift für das Bewegen des Verschlusses 2 in die Steuerkulisse 6 ein und wird durch die Antriebskulisse 9 mitgenommen.A connecting rod 12, which is structurally connected to the closure 2, engages in the control cam 6 for moving the closure 2 and is entrained by the drive cam 9.
Der Schieber 11 weist unterhalb eine nutartige Führung 13 auf, in welcher ein den SchieberThe slider 11 has below a groove-like guide 13, in which a slide
11 antreibendes Teil (15) eingreifen und geführt werden kann (wird noch ausgeführt).11 driving part (15) engage and can be performed (will be executed).
Als Antrieb ist eine umlaufende Kette 14 angedacht, welche durch einen elektrischen Motor 16 angetrieben wird. Die Kette 14 besitzt ein spezielles Kettenglied (Nocken) 15, welches in die Nut 13 des Schiebers 11 eingreift und den Schieber 11 bei Kettenbewegung bewegen kann.As drive a circumferential chain 14 is being considered, which is driven by an electric motor 16. The chain 14 has a special chain link (cam) 15, which engages in the groove 13 of the slider 11 and can move the slider 11 in chain movement.
Der zeitliche als auch funktionale Ablauf wird mit Fig. 1 in Verbindung mit Fig. 3 veranschaulicht: Die Kette 14 wird durch den Motor 16 angetrieben. Der Nocken 15 nimmt dabei den Schieber 11 und dieser den Pleuel 12 mit. Mit dem Pleuel 12 wird der Verschluss 2 in Richtung Waffenrohr 4 gebracht (A= Beginn Verschlussvorlauf). Erreicht die Verriegelungskulisse 10 den Bolzen am Verriegelungsring 3, wird dieser Ring 3 bewegt, der Verschluss 2 verriegelt (B= Beginn der Verriegelung, C= verriegelt). Für die Verriegelungszeit und Schussauslösung (D) bis zum Zeitpunkt der Entriegelung (E), fährt der Nocken 15 die Nut 13 des Schiebers 11 ab. Das fertige Entriegeln (F) wird dann durch Weiterlaufen der Kette 14 und Mitnahme des Nockens 15 eingeleitet. Entsprechend wird dann der Pleuel 12 geführt und der Verschluss 2 geradlinig in die Beladungεpoεition (G= Rücklauf Verschluss) gebracht, der Pleuel abgelegt (H), so dass der Verschluss still steht (J), eine neue Patrone 5 vorgelegt (K) und der Verschluss 2 wieder in Richtung Waffenrohr 4 verfahren (A). In dieser Beladungszeit erfolgt das Weiterlaufen der Kette 14 und ein Zurückgleiten des Nockens 15 innerhalb der Nut 13.The temporal as well as functional sequence is illustrated with FIG. 1 in conjunction with FIG. 3: The chain 14 is driven by the motor 16. The cam 15 takes the slider 11 and this the connecting rod 12 with. With the connecting rod 12, the shutter 2 is brought in the direction of gun barrel 4 (A = beginning of shutter advance). When the locking link 10 reaches the bolt on the locking ring 3, this ring 3 is moved, the bolt 2 locked (B = start of locking, C = locked). For the locking time and shot triggering (D) until the time of unlocking (E), the cam 15 moves the groove 13 of the slider 11 from. The finished unlocking (F) is then initiated by continued running of the chain 14 and entrainment of the cam 15. Correspondingly, the connecting rod 12 is then guided and the closure 2 is brought straight into the loading position (G = return closure), the connecting rod is deposited (H) so that the closure stands still (J), a new cartridge 5 is presented (K) and Move lock 2 back towards gun barrel 4 (A). In this loading time, the continued running of the chain 14 and a sliding back of the cam 15 within the groove 13th
Bereits Fig. 3 zeigt die Einbindung eines Sicherheitskriteriums - einen Schnellstopp 20 - in den Kettenantrieb. Eine solche Einrichtung dient der Erhöhung der Waffensicherheit in punk- to Zündversager. Dieser wird durch die Sicherheitseinrichtung sicher aus dem Waffenrohr 4 gebracht, ohne dadurch die Bedienung als auch die Funktion der Waffe 1 zu gefährden. Der Schnellstopp 20 ist zeitlich vor dem eigentlichen Entriegeln des Verschlusses 2 eingebunden, sollte aber eine Zündverzögerung der Munition 5 berücksichtigen.Already Fig. 3 shows the integration of a safety criterion - a quick stop 20 - in the chain drive. Such a device serves to increase the weapon security in punk to Zündversager. This is brought safely out of the barrel 4 by the safety device without jeopardizing the operation as well as the function of the weapon 1. The quick stop 20 is involved in time before the actual unlocking of the closure 2, but should take into account a Zündverzögerung the ammunition 5.
Der Schnellstopp 20 wirkt funktional mit dem Antrieb 14 sowie dem rücklaufenden Verschluss 2 zusammen. Er besteht aus einem klotzähnlichen Teil 22 mit einer Anphasung 22.1 und untergreift den Antrieb 14 vorzugsweise u-förmig. Andere konstruktive Maßnahmen als das Untergreifen sind auch möglich.The quick stop 20 interacts functionally with the drive 14 and the returning closure 2. It consists of a block-like part 22 with a chamfer 22.1 and engages under the drive 14 preferably U-shaped. Other constructive measures than grasping are also possible.
Der Schnellstopp 20 wird immer eingelegt, wenn der Nocken 15 den Schnellstopp 20 in Schussrichtung gesehen rechtsseitig beim Verschlussvorlauf passiert (Fig.4). Dabei drückt der Nocken 15 den Schnellstopp 20 so weg (Fig. 5), dass er auf der anderen gegenüberliegenden Seite im Transportweg des Nockens 15 (linksseitig) als eingelegt gilt. Der Nocken 15 fährt die Nut 13 in der verriegelten Zeit ab, der Schuss bricht. Mit dem Schuss werden in bekannter Art und Weise die rücklaufenden Waffenteile bewegt. Ein am Verschluss 2 eingebundenes Mittel 21 , beispielsweise ein Aussteuerkeil, fährt auf die Phase 22.1 am Schnellstopp 20 und drückt den Schnellstopp 20 weg, der Nocken 15 kann ungehindert am Schnellstopp 20 vorbeigleiten (Fig. 7). Im Fall einer Zündverzögerung bewegt sich der Verschluss 2 zwar etwas später, jedoch zeitlich ausreichend, damit der Keil 21 den Schnellstopp 20 aussteuern und der Verschluss 2 nach erfolgtem Schuss entriegelt werden kann.The quick stop 20 is always engaged when the cam 15 passes the rapid stop 20 seen in the firing direction on the right side during the closure advance (FIG. 4). In this case, the cam 15 pushes the quick stop 20 away (FIG. 5) so that it is considered to be inlaid on the other opposite side in the transport path of the cam 15 (on the left side). The cam 15 moves the groove 13 in the locked time, the shot breaks. With the shot, the returning weapon parts are moved in a known manner. An integrated means 21 on the closure, for example a Aussteuerkeil, moves to the phase 22.1 on the quick stop 20 and pushes the quick stop 20 away, the cam 15 can pass unhindered past the quick stop 20 (Fig. 7). In the case of an ignition delay, the shutter 2 moves a little later, but sufficient in time so that the wedge 21 can control the rapid stop 20 and the shutter 2 can be unlocked after a successful shot.
Bei einem Zündversagen bleibt bekanntlich der Waffenrücklauf aus, da kein Schuss gebrochen ist. In diesem Fall läuft der Nocken 15 der Kette 14 auf den Schnellstopp 20 auf, die Ketten beweg u ng wird gestoppt, das Entriegeln verhindert (Fig. 8). Ein Lösen oder Freigeben des Schnellstopps 20 wird entweder manuell, oder wie hier vorgeschlagen, durch Ansteuerung eines Magneten 25. d.h elektrisch, vorgenommen, so dass nun der Zündversager wie eine herkömmliche Hülse ausgeworfen werden kann.In a Zündversagen known to the weapon return off, since no shot is broken. In this case, the cam 15 of the chain 14 runs on the quick stop 20, the chain movement is stopped, the unlocking is prevented (FIG. 8). A release or release of the quick stop 20 is either manually, or as suggested here, by driving a magnet 25, that is electrically made, so that now the Zündersager can be ejected like a conventional sleeve.
Der Schnellstopp 20 ist in Belastungsrichtung gefedert bzw. gepuffert (23), um die Kraft zu haben und Materialbruch zu vermeiden. Zur Unterstützung der Haltekraft des Schnellstopps 20 in ein- bzw. ausgesteuerter Position greift ein Keil 26 in Einkerbungen 27 (eingesteuert), 28 (ausgesteuert) ein.The quick stop 20 is sprung or buffered in the direction of loading (23) in order to have the force and avoid material breakage. To support the holding force of the quick stop 20 in the on or off position, a wedge 26 engages in notches 27 (controlled), 28 (controlled).
Damit das ruckartige Bremsen der Kette 14 nicht zu einem Reißen führt, ist eine Kupplung 24, die drehmomentabhängig ist, also eine Art Rutschkupplung oder dergleichen, zwischen Motor und Kette 14 eingebunden.In order for the jerky braking of the chain 14 does not lead to a rupture, a clutch 24, which is torque-dependent, so a kind of slip clutch or the like, between engine and chain 14 is involved.
Der Schnellstopp 20 ist nicht nur bei Kettenantrieben vorzusehen. Vielmehr ist ein Einbinden auch bei getriebetechnischen Lösungen vorteilhaft, die alternativ zum Kettenantrieb einsetzbar sind, wie Zahnräderantriebe, Rückstoßladerantriebe etc. Der Schnellstopp 20 ist auch in die Antriebe einbindbar, welche die Stillstandszeiten selbst definieren, also eine andere Funktionssteuerung aufweisen, als hier beschrieben. The quick stop 20 is not only intended for chain drives. Rather, integration is also advantageous in gearbox solutions that can be used as an alternative to the chain drive, such as gear drives, recoil loader drives, etc. The quick stop 20 can also be integrated in the drives, which define the downtimes themselves, that is, have a different function control than described here.
