Abstract

Bei einer Feuerwaffe mit elevierbarem Waffenrohr (12) muss das Waffenrohr (12) in jeder gewünschten Stellung fixiert werden können. Zu diesem Zweck sind bekannte Waffen mit Bremsvorrichtungen ausgerüstet, bei denen grosse Reibungskräfte auftreten, wodurch Servovorrichtungen erforderlich sind. Erfindungsgemäss wird die Elevation des Waffenrohres (12) mit Hilfe eines Zylinders (17) und eines Kolbens (25) fixiert. Der Kolben weist eine verschliessbare Durchtrittsöffnung (29,40,41) auf, durch welche Druckmittel von einer Kammer (44) auf einer Seite des Kolbens (25) in die andere Kammer (45) auf der anderen Seite des Kolbens (25) fliesst, solange die Durchtrittsöffnung (29,40,41) offen ist, wobei zum Fixieren des Waffenrohres (12) in einer bestimmten Elevation die Durchtrittsöffnung (29,40,41) verschliessbar ist.In the case of a firearm with an elevatable weapon barrel (12), the weapon barrel (12) must be able to be fixed in any desired position. For this purpose, known weapons are equipped with braking devices in which large frictional forces occur, which means that servo devices are required. According to the invention, the elevation of the weapon barrel (12) is fixed with the aid of a cylinder (17) and a piston (25). The piston has a closable passage opening (29, 40, 41) through which pressure medium flows from one chamber (44) on one side of the piston (25) into the other chamber (45) on the other side of the piston (25), as long as the passage opening (29, 40, 41) is open, the passage opening (29, 40, 41) being closable at a certain elevation for fixing the weapon barrel (12).

Description

Die Erfindung betrifft eine elevierbare Feuerwaffe mit einer Vorrichtung zum Einstellen der Elevation des Waffenrohres enthaltend zwei Teile, nämlich einen Zylinder und einen Kolben, der den Zylinder in zwei Kammern unterteilt, von denen der eine Teil am Waffenrohr und der andere Teil an einer ortsfesten Lafette angelenkt ist, wobei beim Elevieren des Waffenrohres sich die beiden Teile relativ zueinander verschieben.The invention relates to an elevatable firearm with a device for adjusting the elevation of the weapon barrel, comprising two parts, namely a cylinder and a piston, which divides the cylinder into two chambers, one part of which is articulated on the gun barrel and the other part on a fixed mount is, the two parts shifting relative to one another when the weapon barrel is being lifted.

Es ist eine Kraftübertragungsvorrichtung dieser Art bekannt (siehe deutsche Offenlegungsschrift Nr.2 424 795; Bofors) zum Einstellen der Neigung eines Geschützrohres. Diese Vorrichtung weist einen Zylinder auf, der schwenkbar am Geschützrohr angelenkt ist und einen Kolben, der über eine Kolbenstange schwenkbar am Traggestell des Geschützes angelenkt ist. Die Verschiebung des Kolbens im Zylinder zum Anheben oder Absenken, d.h. zum Elevieren des Geschützrohres wird durch ein Hydrauliköl erreicht. Es ist ein zweites Druckmittel mit hoher Kompressibilität z.B. Gas vorgesehen, das sich in einer Kammer des Zylinders befindet, und das ein minimales Volumen in der abgesenkten Stellung und ein maximales Volumen in der obersten Stellung des Geschützrohres aufweist, wodurch das eingeschlossene Gas als eine Ausgleichsfeder wirkt, um der durch die Lagerung am Traggestell bedingten Ueberlastigkeit des Geschützrohres entgegenzuwirken.A power transmission device of this type is known (see German Offenlegungsschrift No. 2 424 795; Bofors) for adjusting the inclination of a gun barrel. This device has a cylinder which is pivotally articulated on the gun barrel and a piston which is articulated on the supporting frame of the gun via a piston rod. The displacement of the piston in the cylinder to raise or lower, i.e. hydraulic oil is used to elevate the gun barrel. It is a second pressure medium with high compressibility e.g. Gas is provided which is located in a chamber of the cylinder and which has a minimum volume in the lowered position and a maximum volume in the uppermost position of the gun barrel, whereby the trapped gas acts as a balancing spring to compensate for that caused by the storage on the support frame To counteract overload of the gun barrel.

Eine solche Vorrichtung ist nur erforderlich bei Waffenrohren, bei denen sich der Schwerpunkt des Waffenrohres nicht auf der Elevationsachse befindet und sich daher eine Ueberlastigkeit ergibt. An Waffen, bei denen die Elevationsachse genau durch den Schwerpunkt des Waffenrohres geht, ist eine solche Vorrichtung nicht erforderlich. Bei einer solchen Waffe lässt sich jedoch das Waffenrohr sehr leicht um seine Elevationsachse schwenken und es besteht daher die Gefahr, dass das auf ein bestimmtes Ziel gerichtete Waffenrohr in unbeabsichtigter Weise wieder verschwenkt wird und dann nicht mehr auf das gewünschte Ziel gerichtet ist. Bei einer solchen Waffe ist es daher notwendig, das in die gewünschte Elevation geschwenkte Waffenrohr zu fixieren. Es sind daher Klemmvorrichtungen üblich, bei denen durch Drehen einer Schraube das Waffenrohr in der gewünschten Stellung fixiert oder arretiert werden kann. Solche Klemmvorrichtungen sind jedoch umständlich zu bedienen und wenig zuverlässig, wenn die Schrauben ungenügend angezogen werden.Such a device is only required for gun barrels where the focus of the Gun barrel is not on the elevation axis and therefore there is an overload. Such a device is not required on weapons in which the elevation axis passes exactly through the center of gravity of the weapon barrel. With such a weapon, however, the weapon barrel can be swiveled very easily about its elevation axis and there is therefore the risk that the weapon barrel aimed at a specific target is inadvertently pivoted again and is then no longer aimed at the desired target. With such a weapon, it is therefore necessary to fix the weapon barrel pivoted into the desired elevation. Clamping devices are therefore customary in which the weapon barrel can be fixed or locked in the desired position by turning a screw. However, such clamping devices are cumbersome to use and unreliable if the screws are insufficiently tightened.

Die Aufgabe, die mit der vorliegenden Erfindung gelöst werden soll, besteht in der Schaffung einer Vorrichtung zum Einstellen oder Fixieren des Waffenrohres in der gewünschten Elevation, die zuverlässiger ist und sich leichter bedienen lässt und die insbesondere unabhängig ist von der Haftreibung einer Klemmvorrichtung.The object to be achieved with the present invention is to provide a device for adjusting or fixing the weapon barrel in the desired elevation, which is more reliable and easier to use and which is in particular independent of the static friction of a clamping device.

Die Vorrichtung, mit der diese Aufgabe gelöst wird, ist dadurch gekennzeichnet, dass der Kolben eine verschliessbare Durchtrittsöffnung aufweist, durch welche Druckmittel von einer Kammer auf einer Seite des Kolbens in die andere Kammer auf der anderen Seite des Kolbens fliesst, solange die Durchtrittsöffnung offen ist, wobei zum Arretieren des Waffenrohres in einer bestimmten Elevation die Durchtrittsöffnung verschliessbar ist, wodurch der Kolben im Zylinder blockiert und das Waffenrohr arretiert oder fixiert ist.The device with which this object is achieved is characterized in that the piston has a closable passage opening, through which pressure medium flows from one chamber on one side of the piston into the other chamber on the other side of the piston, as long as the passage opening is open , The passage opening being closable for locking the weapon barrel at a certain elevation, as a result of which the piston in the cylinder is blocked and the weapon barrel is locked or fixed.

Vorzugsweise befinden sich in der Durchtrittsöffnung des Kolbens zwei betätigbare Rückschlagventile.There are preferably two actuable check valves in the passage opening of the piston.

Der Vorteil dieser Vorrichtung besteht darin, dass keine grossen Kräfte zum Fixieren des Waffenrohres in einer bestimmten Elevation erforderlich sind, wie diese bei Klemm- oder Bremsvorrichtungen auftreten.The advantage of this device is that no great forces are required to fix the weapon barrel at a certain elevation, as occurs with clamping or braking devices.

Gemäss Fig.1-3 weist die Feuerwaffe 10 ein Waffengehäuse 11 auf mit einem Waffenrohr 12, das am Waffengehäuse 11 befestigt ist. Diese Feuerwaffe 10 ist auf einer Lafette 13 um eine Elevationsachse 14 schwenkbar gelagert. Die Lafette 13 besteht gemäss Fig.2 aus einer Bodenplatte 15 und zwei Stützen 16, auf denen die Waffe 10 schwenkbar gelagert ist. Das Waffenrohr 12 kann dabei aus der gezeigten horizontalen Lage um ca. 45-50° eleviert werden. Diese Elevation der Feuerwaffe erfolgt von Hand durch den Schützen, es sind keine weiteren Hilfsmittel vorhanden. Damit die Waffe 10 in jeder gewünschten Elevation stufenlos arretiert werden kann, dient die im folgenden beschriebene Vorrichtung.1-3, the firearm 10 has a weapon housing 11 with a weapon barrel 12 which is fastened to the weapon housing 11. This firearm 10 is mounted on a carriage 13 so as to be pivotable about an elevation axis 14. According to FIG. 2, the mount 13 consists of a base plate 15 and two supports 16 on which the weapon 10 is pivotably mounted. The weapon barrel 12 can be raised from the horizontal position shown by approximately 45-50 °. This elevation of the firearm is done by the shooter by hand, there are no other aids. So that the weapon 10 can be locked in any desired elevation, the device described below is used.

Diese Vorrichtung weist gemäss Fig.1 einen Zylinder 17 auf, der mit Hilfe eines Gelenkes 18 schwenkbar an der Bodenplatte 15 befestigt ist. Aus diesem Zylinder 17 ragt eine Kolbenstange 19 heraus, die mit Hilfe eines Gelenkes 20 schwenkbar am Waffengehäuse 11 befestigt ist. Wie aus Fig.1 ersichtlich, verschiebt sich beim Elevieren der Waffen 10 die Kolbenstange 19 mit dem daran befestigten Kolben gegenüber dem Zylinder 17. Der Aufbau dieser Vorrichtung ist in Fig.4 und 5 dargestellt.According to FIG. 1, this device has a cylinder 17 on, which is pivotally attached to the base plate 15 by means of a joint 18. A piston rod 19 protrudes from this cylinder 17 and is pivotably attached to the weapon housing 11 by means of a joint 20. As can be seen from FIG. 1, when the weapons 10 are raised, the piston rod 19 with the piston attached to it moves relative to the cylinder 17. The structure of this device is shown in FIGS. 4 and 5.

Gemäss Fig.4 weist der Zylinder 17 ein Rohr 21 auf, das in Fig.4 stark verkürzt dargestellt ist. Dieses Rohr 21 ist an seinem linken Ende durch einen Deckel 22 verschlossen. An diesem Deckel 22 ist ein weiteres Rohr 23 befestigt, das an seinem linken Ende das Gelenk 18 aufweist. Das Rohr 21 ist ferner an seinem rechten Ende durch einen zweiten Deckel 24 verschlossen. Die Kolbenstange 19 ragt durch diesen Deckel 24 hindurch in das Rohr 21 hinein und weist an ihrem linken Ende einen Kolben 25 auf und an ihrem rechten Ende das Gelenk 20. In den Zylinder 17 kann Druckflüssigkeit durch Einfüllöffnungen in den Deckeln 22 und 24 eingefüllt werden. Diese Einfüllöffnungen sind durch zwei Verschlusschrauben 26 und 27 verschliessbar, wodurch dann im Zylinder ein konstanter Druck aufgebaut werden kann. Damit die Druckflüssigkeit zu beiden Seiten des Kolbens 25 gleich grosse Flächen beaufschlagt, ist an beiden Seiten des Kolbens 25 je eine Kolbenstange befestigt, nämlich auf der rechten Seite des Kolbens 25 die bereits erwähnte Kolbenstange 19 und auf der linken Seite des Kolbens 25 noch eine weitere Kolbenstange 28. Diese weitere Kolbenstange 28 ragt durch den erwähnten Deckel 22 hindurch. Solange somit zu beiden Seiten des Kolbens 25 derselbe Druck herrscht und der Kolben 25 völlig dicht ist, kann er sich im Zylinder 17 nicht verschieben. Damit der Kolben 25 im Zylinder 17 verschoben werden kann, ist im Kolben 25 eine verschliessbare Durchtrittsöffnung vorhanden. Diese verschliessbare Durchtrittsöffnung des Kolbens 25 weist gemäss Fig.5 zwei betätigbare Rückschlagventile 29 auf, die sich in einer Radialbohrung 30 des Kolbens 25 befinden. Jedes dieser Rückschlagventile 29 besitzt eine bewegliche Halbkugel 31, welche durch eine Feder 32 gegen einen Dichtungssitz 33 angedrückt wird. Zur Betätigung der Halbkugel 31, d.h. zum Abheben der Halbkugel 31 von ihrem Sitz 33 dient eine verschiebbare Stange 34, welche eine ringförmige Aussparung 35 aufweist. Diese Aussparung 35 ist auf einer Seite durch eine Kegelfläche 36 begrenzt, die zur Betätigung der Halbkugel 31 dient. Die verschiebbare Stange 34 weist eine Schulter 37 auf, auf der sich das eine Ende einer Druckfeder 38 abstützt, wie aus Fig.4 ersichtlich ist. Die Druckfeder 38 stützt sich mit ihrem anderen Ende auf einer Schulter 39 der Kolbenstange 19 ab. Diese Druckfeder 38 hat das Bestreben, die Stange 34 soweit nach rechts zu verschieben, dass die Kegelfläche 36 aus dem Bereich der Halbkugeln 31 gelangt und die Rückschlagventile 29 geschlossen sind. Zum Oeffnen der beiden Rückschlagventile 29 muss die Stange 34 soweit nach links geschoben werden, bis die Kegelfläche 36 die beiden Halbkugeln 31 von ihren Sitzen 33 abhebt. Sobald die Halbkugeln 31 von ihren Sitzen 33 abgehoben sind, kann die Druckflüssigkeit von der einen Seite des Kolbens 25 zur anderen Seite des Kolbens 25 gelangen, und zwar gelangt die Flüssigkeit durch eine erste axiale Bohrung 40 zum ersten und dann zum zweiten Rückschlagventil 29 und dann durch eine zweite axiale Bohrung 41 auf die andere Seite des Kolbens 25 oder umgekehrt, je nachdem in welcher Richtung der Kolben 25 verschoben werden soll. Zum Verschieben der Stange 34 dient ein zweiarmiger, an der Kolbenstange 19 schwenkbar angelenkter Hebel 42, dessen einer Arm sich auf das Ende der Stange 34 abstützt und an dessen anderem Arm ein Kabelzug 43 angelenkt ist. Wenn an diesem Kabelzug 43 gezogen wird, dreht sich der zweiarmige Hebel 42 im Uhrzeigersinne in die gestrichelt dargestellte Lage (Fig.4) und verschiebt dabei die Stange 34 soweit nach links, dass sich die beiden Rückschlagventile 29 öffnen, sodass sich der Kolben 25 beliebig nach rechts oder links verschieben lässt. Dadurch kann die Feuerwaffe 10 beliebig eleviert werden. Durch Freigabe des Kabelzuges 43 wird die Stange 34 durch die Feder 38 wieder so weit nach rechts verschoben, dass sich die beiden Rückschlagventile 29 schliessen und der Kolben 25 sich nicht mehr verschieben lässt und somit die Feuerwaffe 10 arretiert ist und sich nicht mehr elevieren lässt, d.h. der Elevationswinkel lässt sich weder vergrössern noch verkleinern.According to FIG. 4, the cylinder 17 has a tube 21, which is shown in shortened form in FIG. This tube 21 is closed at its left end by a cover 22. A further tube 23 is attached to this cover 22 and has the joint 18 at its left end. The tube 21 is also closed at its right end by a second cover 24. The piston rod 19 projects through this cover 24 into the tube 21 and has a piston 25 at its left end and the joint 20 at its right end. Pressure fluid can be filled into the cylinder 17 through filler openings in the covers 22 and 24. These filler openings can be closed by two screw plugs 26 and 27, as a result of which a constant pressure can then be built up in the cylinder. So that the pressure fluid acts on surfaces of the same size on both sides of the piston 25, a piston rod is attached to both sides of the piston 25, namely the already mentioned piston rod 19 on the right side of the piston 25 and yet another on the left side of the piston 25 Piston rod 28. This further piston rod 28 projects through the aforementioned cover 22. As long as there is the same pressure on both sides of the piston 25 and the piston 25 is completely tight, it cannot move in the cylinder 17. So that the piston 25 can be moved in the cylinder 17, there is a closable passage opening in the piston 25 available. According to FIG. 5, this closable passage opening of the piston 25 has two actuable check valves 29, which are located in a radial bore 30 of the piston 25. Each of these check valves 29 has a movable hemisphere 31, which is pressed against a sealing seat 33 by a spring 32. A slidable rod 34, which has an annular recess 35, is used to actuate the hemisphere 31, ie to lift the hemisphere 31 from its seat 33. This recess 35 is delimited on one side by a conical surface 36 which serves to actuate the hemisphere 31. The displaceable rod 34 has a shoulder 37 on which one end of a compression spring 38 is supported, as can be seen in FIG. The compression spring 38 is supported with its other end on a shoulder 39 of the piston rod 19. This compression spring 38 tends to shift the rod 34 to the right so far that the conical surface 36 comes out of the area of the hemispheres 31 and the check valves 29 are closed. In order to open the two check valves 29, the rod 34 must be pushed to the left until the conical surface 36 lifts the two hemispheres 31 from their seats 33. As soon as the hemispheres 31 are lifted off their seats 33, the pressure fluid can pass from one side of the piston 25 to the other side of the piston 25, namely the fluid passes through a first axial bore 40 to the first and then to the second check valve 29 and then through a second axial bore 41 to the other side of the piston 25 or vice versa, depending on the direction in which the piston 25 is to be displaced. A two-armed lever 42, pivoted on the piston rod 19, serves to move the rod 34, one arm of which is supported on the end of the rod 34 and a cable pull 43 is connected to the other arm. When pulling on this cable 43, the turns two-armed lever 42 in the clockwise direction into the position shown in dashed lines (FIG. 4) and thereby moves the rod 34 to the left so far that the two check valves 29 open, so that the piston 25 can be shifted to the right or left as desired. As a result, the firearm 10 can be raised as desired. By releasing the cable pull 43, the rod 34 is again pushed so far to the right by the spring 38 that the two check valves 29 close and the piston 25 can no longer be displaced and thus the firearm 10 is locked and can no longer be raised, ie the elevation angle cannot be increased or decreased.
