Description

Die Erfindung betrifft eine Vorrichtung zum Entladen einer Mörserpatrone aus einem Waffenrohr eines Vorderladermörsers.The invention relates to a device for unloading a mortar cartridge from a barrel of a Vorderladermörsers.

Um eine Patrone aus dem Waffenrohr eines Vorderladermörsers wieder zu entladen, muß das Waffenrohr von der Bedienmannschaft des Mörsers entweder mit der Mündung nach unten gekippt werden, sofern dieses möglich ist, oder es muß eine spezielle Entladevorrichtung benutzt werden.In order to unload a cartridge from the barrel of a muzzle loader mortar, the gun barrel must be tilted by the operator of the mortar either with the mouth down, if this is possible, or a special unloading device must be used.

Als Entladevorrichtung ist bereits ein in das Waffenrohr des Mörsers einführbarer Körper vorgeschlagen worden, der auf seiner der Patrone zugewandten Seite mindestens zwei federbelastete Klinken umfaßt. Zum Entladen der Patrone wird die Entladevorrichtung in die Rohrmündung eingeführt und an zwei Leinen in das Waffenrohr herabgelassen, bis die Klinken in eine umlaufende Rille der Patrone einrasten und so eine formschlüssige Verbindung zu dieser herstellen. Anschließend wird dann die Entladevorrichtung zusammen mit der Mörserpatrone mündungsseitig aus dem Waffenrohr herausgezogen.As an unloading an insertable into the barrel of the mortar body has already been proposed, which comprises on its side facing the cartridge at least two spring-loaded pawls. To unload the cartridge, the unloading device is inserted into the muzzle and lowered on two lines in the gun barrel until the pawls engage in a circumferential groove of the cartridge and so make a positive connection to this. Subsequently, the unloading device is then withdrawn together with the mortar cartridge mouth side of the barrel.

Nachteilig ist bei dieser Entladevorrichtung unter anderem, dass an der Patrone eine Rille oder Nut vorhanden sein muß, die den Luftwiderstand des abgefeuerten Mörsergeschosses erhöht. Derartige Geschosse weisen daher eine geringere Reichweite als vergleichbare Geschosse ohne Auszugsrillen auf. Außerdem beeinflußt der erhöhte Luftwiderstand die Treffgenauigkeit des entsprechenden Geschosses in der Regel negativ.A disadvantage of this unloading device, inter alia, that on the cartridge, a groove or groove must be present, which increases the air resistance of the mortar fired mortar. Such projectiles therefore have a shorter range than comparable projectiles without Auszugsrillen. In addition, the increased air resistance affects the accuracy of the corresponding projectile generally negative.

Als nachteilig hat es sich ferner erwiesen, dass bei der vorstehend erwähnten Entladevorrichtung die Verbindung zur Mörserpatrone innerhalb des Waffenrohres nicht wieder gelöst werden kann. Sofern sich daher zwischen Patrone und Waffenrohr Schmutzpartikel oder Treibladungsreste befinden, die ein Entladen der Patrone verhindern, muß unter Umständen die gesamte Waffe demontiert werden, um die Patrone und die Entladevorrichtung aus dem Waffenrohr wieder zu entfernen.A disadvantage, it has also been found that the connection to the mortar cartridge inside the gun barrel can not be solved again in the unloading device mentioned above. Therefore, if between the cartridge and gun barrel dirt particles or propellant residues that prevent discharge of the cartridge may need to be disassembled the entire weapon to remove the cartridge and the unloading device from the gun barrel again.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Entladen einer Mörserpatrone anzugeben, bei deren Einsatz an der Mörserpatrone Rillen oder sonstige Formelemente, welche die Aerodynamik der Patrone nachteilig beeinflussen, entfallen können. Vorzugsweise soll die erfindungsgemäße Vorrichtung auf einfache Weise derart ausgebildet werden, dass bei Bedarf die Patrone innerhalb des Waffenrohres von der Entladevorrichtung wieder abgekoppelt und somit der Entladevorgang abgebrochen werden kann.The invention has for its object to provide a device for unloading a mortar cartridge, when used on the mortar cartridge grooves or other form elements that adversely affect the aerodynamics of the cartridge can be omitted. Preferably, the device according to the invention should be designed in a simple manner such that, if necessary, the cartridge within the gun barrel of the unloading device decoupled again and thus the discharge process can be canceled.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, dass der in das Waffenrohr einführbare Körper auf seiner der Mörserpatrone zugewandten Seite Mittel aufweist, mit deren Hilfe statt einer Formschlussverbindung eine Kraftschlussverbindung zwischen dem Körper und dem vorderen Bereich der Mörserpatrone herstellbar ist, die groß genug ist, um die Mörserpatrone mittels der Halteteile aus dem Waffenrohr herauszuziehen.The invention is based essentially on the idea that the insertable into the gun barrel body has on its side facing the mortar cartridge means by which instead of a positive connection, a frictional connection between the body and the front portion of the mortar cartridge can be produced, which is large enough to extract the mortar cartridge from the gun barrel by means of the holding parts.

Bei einer ersten, besonders vorteilhaften Ausführungsform der Erfindung handelt es sich bei den Mitteln zur Herstellung der Kraftschlussverbindung zwischen dem Körper und der Mörserpatrone um mindestens zwei gleichmäßig über den Umfang verteilt angeordnete und seitlich auf den vorderen Teil der Mörserpatrone angreifende Magnete, die vorzugsweise auf ihrer der Mörserpatrone zugewandten Seite eine an die Oberfläche der Mörserpatrone angepasste Form aufweisen. Die Verwendung derartiger Magnete setzt allerdings voraus, dass es sich bei der Geschoßhülle der Mörserpatrone um ein ferromagnetisches Material (in der Regel Stahl) handelt.In a first, particularly advantageous embodiment of the invention, the means for producing the frictional connection between the body and the mortar are at least two evenly distributed over the circumference arranged and laterally acting on the front part of the mortar magnets, preferably on their Mortar cartridge facing side have adapted to the surface of the mortar cartridge shape. However, the use of such magnets presupposes that the projectile casing of the mortar cartridge is a ferromagnetic material (usually steel).

Um auf einfache Weise bei Bedarf die Patrone im Waffenrohr von der Vorrichtung abzukoppeln, kann als Magnet ein Elektromagnet verwendet werden, bei dem der durch die Spule fließende Strom an- bzw. abgeschaltet wird.In order to decouple the cartridge in the gun barrel from the device in a simple manner when required, a solenoid can be used as a magnet in which the current flowing through the coil is switched on or off.

Es kann sich bei dem Magneten aber auch um einen Permanentmagneten handeln. In diesem Fall werden zur Entkopplung der erfindungsgemäßen Vorrichtung und der Patrone die Magnete mittels eines Gestänges schwenkbar an dem in das Waffenrohr einführbaren Körper befestigt, derart, dass mittels eines mit dem Gestänge verbundenen und mindestens bis zur Mündung des Waffenrohres reichenden Entsperrteiles, z.B. eines Seiles, die Magnete von der Mörserpatrone wegschwenkbar sind und dadurch die Kraftschlussverbindung zwischen dem Körper und den Magneten aufgehoben wird.However, the magnet can also be a permanent magnet. In this case, for decoupling of the device according to the invention and the cartridge, the magnets are pivotally attached by means of a linkage to the body insertable into the gun barrel, such that by means of a connected to the linkage and at least to the mouth of the gun barrel reaching Entsperrteiles, e.g. a rope, the magnets are pivoted away from the mortar cartridge and thereby the frictional connection between the body and the magnet is released.

Bei einer zweiten, von dem Material der Geschoßhülle unabhängigen Ausführungsform der Erfindung handelt es sich bei den Mitteln zur Herstellung der Kraftschlussverbindung zwischen dem Körper und der Mörserpatrone um ein mit dem Körper verbundenes, eine Ausnehmung aufweisendes Teil, welches bei seiner bestimmungsgemäßen Verwendung den vorderen Bereich der Mörserpatrone derart umschließt, dass zwischen der Oberfläche der Mörserpatrone und der Oberfläche der Ausnehmung ein evakuierbarer Raum verbleibt, welcher einerseits mittels eines zwischen der Oberfläche der Patrone und der Oberfläche der Ausnehmung anordbaren Dichtelementes abdichtbar und andererseits über eine Leitung, z.B. mittels einer Vakuum-Handpumpe, evakuierbar ist.In a second, independent of the material of the projectile casing embodiment of the invention, the means for producing the frictional connection between the body and the mortar cartridge to a body connected to the recess having a part, which in its intended use, the front portion of Mortar cartridge surrounds such that between the surface of the mortar cartridge and the surface of the recess an evacuable space remains, which on the one hand by means of an attachable between the surface of the cartridge and the surface of the recess sealing member and on the other hand via a conduit, eg by means of a vacuum hand pump, is evacuated.

Vorzugsweise sind das die Ausnehmung umfassende Teil und der Körper der erfindungsgemäßen Vorrichtung einstückig miteinander verbunden.Preferably, the part comprising the recess and the body of the device according to the invention are integrally connected to one another.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausfiihrungsbeispielen. Es zeigen:

  • Fig.2 eine vergrößerte Ansicht des in Fig.1 mit II bezeichneten Bereiches und
  • Fig.3 einen Fig.1 entsprechenden Längsschnitt eines Waffenrohres mit einem zweiten Ausfiihrungsbeispiel einer erfindungsgemäßen Vorrichtung.
Further details and advantages of the invention will become apparent from the following Ausführungsbeispielen explained with reference to figures. Show it:
  • 1 shows the longitudinal section of the weapon barrel of a Vorderladermörsers with a cartridge therein and a first Ausfiihrungsbeispiel of a device according to the invention.
  • 2 is an enlarged view of the designated II in Fig.1 area and
  • 3 shows a longitudinal section corresponding to Figure 1 of a weapon barrel with a second Ausfiihrungsbeispiel a device according to the invention.

In Fig. 1 ist mit 1 das Waffenrohr eines Vorderladermörsers bezeichnet, in dem sich eine Mörserpatrone 2 mit einer aus Stahl bestehenden Geschoßhülle 3 befindet. Auf der der Mündung 4 des Waffenrohres 1 zugewandten Seite befindet sich in dem Waffenrohr 1 eine erfindungsgemäße Vorrichtung 5 zum Entladen der Mörserpatrone 2.In Fig. 1, 1 denotes the gun barrel of a Vorderladermörsers in which a mortar cartridge 2 is located with a projectile casing 3 made of steel. On the side facing the mouth 4 of the gun barrel 1 is located in the barrel 1 an inventive device 5 for unloading the mortar. 2

Die Vorrichtung 5 umfaßt einen Körper 6, der mit zwei Zugseilen 7 verbunden ist, welche aus der Mündung 4 des Waffenrohres 1 herausgeführt sind. Auf der der Mörserpatrone 2 zugewandten Seite des Körpers 6 sind gegenüberliegend zwei Permanentmagnete 8 angeordnet. Die Magnete 8 weisen auf ihrer der Mörserpatrone 2 zugewandten Seite eine an die Oberfläche 9 der Mörserpatrone 2 angepaßte Form auf und sind in der in Fig. 1 dargestellten Anordnung aufgrund der von ihnen auf die Mörserpatrone 2 ausgeübte Magnetkraft kraftschlüssig mit dieser verbunden (Fig.2).The device 5 comprises a body 6 which is connected to two tension cables 7, which are led out of the mouth 4 of the weapon barrel 1. On the mortar of the cartridge 2 facing side of the body 6, two permanent magnets 8 are arranged opposite one another. The magnets 8 have on their the mortar cartridge 2 facing side on the surface 9 of the mortar cartridge 2 adapted shape and are in the arrangement shown in FIG. 1 due to the force exerted on the mortar cartridge 2 magnetic force positively connected thereto (Fig ).

Zum Entladen der Mörserpatrone 2 wird die Vorrichtung 5 von der Mündung 4 her in das Waffenrohr 1 mit Hilfe der Zugseile 7 heruntergelassen. Sie setzt sich dann auf die Mörserpatrone 2 und die als Formstücke ausgebildeten Permanentmagnete 8 schmiegen sich an die Patrone 2 an. Anschließend kann dann die erfindungsgemäße Vorrichtung 5 mit der Mörserpatrone 2 aus dem Waffenrohr 1 herausgezogen werden.To unload the mortar cartridge 2, the device 5 is lowered from the mouth 4 forth in the barrel 1 by means of the traction cables 7. She then sits down on the mortar cartridge 2 and formed as fittings permanent magnets 8 nestle against the cartridge 2. Subsequently, the device 5 according to the invention can then be pulled out of the weapon barrel 1 with the mortar cartridge 2.

Wie den Fig.1 und 2 entnehmbar ist, sind die beiden Permanentmagnete 8 jeweils um eine Drehachse 10 schwenkbar an dem Körper 6 befestigt. Die Schwenkbewegung erfolgt dabei mittels eines nur schematisch angedeuteten Gestänges 11, welches einerseits an den Magneten 8 und andererseits mit einem mindestens bis zur Mündung 4 des Waffenrohres reichenden, als Seil ausgebildeten Entsperrteiles 12 verbunden ist. Beim Ziehen dieses Seiles 12 werden die beiden Magnete 8 jeweils um die Drehachse 10 von der Mörserpatrone 2 weggeschwenkt (gelüftet) und dadurch die Kraftschlussverbindung zwischen der Mörserpatrone 2 und der Vorrichtung 5 aufgehoben, so dass die Vorrichtung 5 mit Hilfe der Zugseile 7 ohne die Mörserpatrone 2 aus dem Waffenrohr 1 wieder herausgezogen werden kann.As can be seen in Figures 1 and 2, the two permanent magnets 8 are each pivotally mounted about an axis of rotation 10 on the body 6. The pivoting movement takes place by means of only schematically indicated linkage 11, which is connected on the one hand to the magnet 8 and on the other hand with a reaching at least to the mouth 4 of the gun barrel, designed as a rope unlocking part 12. When pulling this rope 12, the two magnets 8 are each pivoted away about the axis of rotation 10 of the mortar cartridge 2 (released) and thereby repealed the frictional connection between the mortar cartridge 2 and the device 5, so that the device 5 by means of the traction cables 7 without the mortar cartridge 2 can be pulled out of the barrel 1 again.

Statt der Verwendung von Permanentmagneten 8 kann die erfindungsgemäße Vorrichtung auch mit Elektromagneten versehen werden, wobei dann Kabel zur Stromversorgung der Elektromagnete aus der Mündung des Waffenrohres herausgeführt und mit einer Stromquelle verbunden werden müssen.Instead of using permanent magnets 8, the device according to the invention can also be provided with electromagnets, in which case cables for the power supply of the electromagnets must be brought out of the mouth of the weapon barrel and connected to a power source.

In einem derartigen Fall kann das in Fig.1 dargestellte Gestänge 11 entfallen, und die Elektromagnete können starr an dem Körper 6 angeordnet werden. Die kraftschlüssige Verbindung zwischen den Magneten und der Mörserpatrone 2 erfolgt dann durch Bestromung der Elektromagnete. Bei Unterbrechung des Stromflusses sind die Entladevorrichtung und die Mörserpatrone automatisch voneinander entkoppelt.In such a case, the linkage 11 shown in Figure 1 can be omitted, and the electromagnets can be rigidly arranged on the body 6. The frictional connection between the magnet and the mortar cartridge 2 is then carried out by energizing the electromagnets. When the current flow is interrupted, the unloading device and the mortar cartridge are automatically decoupled from each other.

In Fig.3 ist ein weiteres Ausführungsbeispiel der Erfindung dargestellt. Dabei ist mit 1 wiederum ein Waffenrohr eines Vorderladermörsers bezeichnet, in dem sich eine Mörserpatrone 2 mit einer Geschoßhülle 3 befindet. Auf der der Mündung 4 des Waffenrohres 1 zugewandten Seite befindet sich in dem Waffenrohr 1 eine mit 5' bezeichnete erfindungsgemäße Vorrichtung zum Entladen der Mörserpatrone 2.In Figure 3, another embodiment of the invention is shown. In this case, 1 again denotes a weapon barrel of a front load mortar, in which a mortar cartridge 2 with a projectile casing 3 is located. On the side facing the mouth 4 of the gun barrel 1 is located in the barrel 1 with a designated 5 'inventive device for unloading the mortar cartridge. 2

Diese Vorrichtung umfaßt wiederum einen Körper 6', der mit zwei Zugseilen 7 verbunden ist, welche aus der Mündung 4 des Waffenrohres 1 herausgeführt sind. Auf der der Mörserpatrone 2 zugewandten Seite des Körpers 6' weist dieser eine glockenförmig ausgebildete Ausnehmung 13 auf, welche den vorderen Bereich der Mörserpatrone 2 derart umschließt, dass zwischen der Oberfläche 9 der Mörserpatrone 2 und der Oberfläche 14 der Ausnehmung 13 ein evakuierbarer Raum 15 verbleibt. Dieser Raum 15 ist einerseits mittels einem zwischen der Oberfläche 9 der Mörserpatrone 2 und der Oberfläche 14 der Ausnehmung 13 angeordneten Dichtelement (Ringdichtung) 16 abgedichtet und andererseits über eine durch den Körper 6' hindurchgeführte Leitung 17 evakuierbar.This device in turn comprises a body 6 ', which is connected to two tension cables 7, which are led out of the mouth 4 of the gun barrel 1. On the mortar of the cartridge 2 facing side of the body 6 ', this has a bell-shaped recess 13 which surrounds the front portion of the mortar cartridge 2 such that between the surface 9 of the mortar cartridge 2 and the surface 14 of the recess 13 an evacuatable space 15 remains , On the one hand, this space 15 is sealed by means of a sealing element (ring seal) 16 arranged between the surface 9 of the mortar cartridge 2 and the surface 14 of the recess 13 and, on the other hand, can be evacuated via a line 17 passed through the body 6 '.

Zur Evakuierung des Raumes 15 zwischen der Entladevorrichtung 5' und der Mörserpatrone 2 ist an der Leitung 17 ein entsprechender Schlauch 18 befestigt, der aus der Mündung 4 des Waffenrohres 1 vorderseitig herausgeführt und beispielsweise mit einer in Fig.3 gestrichelt angedeuteten Vakuum-Handpumpe 19 verbunden ist.For evacuation of the space 15 between the unloading device 5 'and the mortar cartridge 2, a corresponding hose 18 is attached to the line 17, which led out of the mouth 4 of the gun barrel 1 on the front side and connected, for example, with a dashed line in Fig.3 indicated vacuum hand pump 19 is.

Zum Entladen der Mörserpatrone 2 wird die erfindungsgemäße Vorrichtung 5' von der Mündung 4 des Waffenrohres 1 her mit Hilfe der beiden Zugseile 7 in das Waffenrohr 1 heruntergelassen. Die Vorrichtung 5' setzt sich auf die Mörserpatrone 2 und das Dichtelement 16 schmiegt sich an der Patrone 2 an. Danach wird mittels der Vakuum-Handpumpe 19 der Raum 15 zwischen Patrone 2 und dem Körper 6' evakuiert. Anschließend kann die Vorrichtung 5' zusammen mit der Mörserpatrone 2 an den beiden Zugseilen 7 aus dem Waffenrohr 1 herausgezogen werden.To unload the mortar cartridge 2, the device 5 'according to the invention is lowered from the mouth 4 of the weapon barrel 1 with the aid of the two traction cables 7 into the barrel 1. The device 5 'sits on the mortar cartridge 2 and the sealing element 16 conforms to the cartridge 2 at. Thereafter, the space 15 between the cartridge 2 and the body 6 'is evacuated by means of the vacuum hand pump 19. Subsequently, the device 5 'can be pulled out of the barrel 1 together with the mortar cartridge 2 at the two tension cables 7.

Bei Bedarf kann der Raum 15 belüftet und die Vorrichtung 5' kann ohne Mörserpatrone 2 dem Waffenrohr 1 entnommen werden.If necessary, the space 15 vented and the device 5 'can be removed without mortar cartridge 2 the gun barrel 1.
