Abstract

A training cartridge includes a metallic cartridge case with a case shoulder and dummy projectile having a gas exhaust opening at its front end. A propellant charge powder chamber of the cartridge case is closed in the forward direction by means of a cup-shaped closure element that is inserted in the cartridge case close to the case shoulder and that bursts or ruptures during firing under the action of the powder gases along predetermined intentional breaking zones. Toward the rear, the powder chamber is sealed by means of a bottom piece inserted in the cartridge case. By placing the intentional opening zones into the interior of the cartridge, danger of injury by the ejected cartridge case is reduced to a minimum.

Description

Die Erfindung betrifft eine Manöverpatrone der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a maneuver cartridge of the type specified in the preamble of claim 1.

Bekannt sind Manöverpatronen aus Metall, Kunststoff oder aus einer Kombination dieser Stoffe. Je nach Konstruktions art weisen die einzelnen Ausführungen dieser Obungspatronen für Manöverzwecke Vor- und Nachteile auf, die sich sowohl in der Innenballistik bzw. der Waffenfunktion äußern können als auch im Verhalten der nach dem Verschuß ausgeworfenen Patronenreste. Bei der weit verbreiteten Art einer Manöverpatrone mit einer Patronenhülse aus Kunststoff und in diese eingesetztem metallischen Bodenstück ist aufgrund der relativ kleinen Restmasse und der Art des Materials beim Patronenauswurf nicht mit Verletzungen des Schützens oder von Personen zu rechnen, die sich im Auswurfbereich der Waffe aufhalten.Maneuver cartridges made of metal, plastic or a combination of these substances are known. Depending on the type of construction, the individual versions of these maintenance cartridges for maneuvering purposes have advantages and disadvantages, which can manifest themselves both in the interior ballistics or the weapon function, as well as in the behavior of the cartridge residues ejected after the shot. With the widespread type of maneuver cartridge with a cartridge case made of plastic and a metal bottom piece inserted into it, due to the relatively small remaining mass and the type of material used in cartridge ejection, injuries to the rifle or to persons who are in the ejection area of the weapon are not to be expected.

Bei Manöverpatronen aus Metall ist das Gefahrenmoment dagegen wesentlich erhöht, und zwar sowohl durch das in der Regel höhere Gewicht des Patronenrestes als auch vor allem durch die scharfkantige Ausführung der beim Schuß entstehenden öffnungsstelle der gegenüber der Patrone für den scharfen Schuß nachgeahmten hohlen Geschoßspitze.In the case of metal maneuver cartridges, on the other hand, the moment of danger is significantly increased, both by the generally higher weight of the remainder of the cartridge and above all by the sharp-edged design of the shot resulting opening point of the hollow bullet tip imitated opposite the cartridge for the sharp shot.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Manöder Verpatrone/im Oberbegriff des Anspruchs 1 angegebenen Art insbesondere den zuletzt genannten Nachteil zu vermeiden, d.h. diese so auszubilden, daß die Verletzungsgefahr durch den ausgeworfenen Patronenkörper auf ein Minimum reduziert wird.The invention has for its object to avoid the last-mentioned disadvantage in a Manöder V erpatrone / specified in the preamble of claim 1, that is, to design it so that the risk of injury from the ejected cartridge body is reduced to a minimum.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Ausbildung entsprechend dem Kennzeichen des Anspruchs 1. Damit ist es in vorteilhafter Weise möglich, das Auftreten von Verletzungen ermöglichenden scharfkantigen Rändern, Bereichen oder dgl. von mehr oder weniger unregelmäßiger Form am vorderen Ende der Geschoßnachbildung zu vermeiden. Bevorzugt ist die Geschoßnachbildung an ihrer Spitze mit einer einzigen Gasabströmöffnung versehen, deren Durchmesser etwa 3o bis 7o % des Geschoßkalibers beträgt.This object is achieved according to the invention by the design according to the characterizing part of claim 1. This advantageously makes it possible to avoid the occurrence of sharp edges, areas or the like which allow injuries to occur and which have a more or less irregular shape at the front end of the projectile replica. The projectile replica is preferably provided at its tip with a single gas outflow opening, the diameter of which is approximately 3o to 7o% of the projectile caliber.

Die Patronenhülse ist als dünnwandige Metallhülle aus z.B. Stahl oder Messing ausgeführt, welche die äußere Form einer kalibergerechten Patrone einschließlich Geschoßkörper, jedoch keinen Patronenboden aufweist. Solche Hülse können vorzugsweise durch Tiefziehen von Metallbändern in geeigneten Folgewerkzeugen hergestellt werden.The cartridge case is a thin-walled metal case made of e.g. Steel or brass, which has the outer shape of a caliber-compatible cartridge including the projectile body, but no cartridge bottom. Such sleeves can preferably be produced by deep drawing metal strips in suitable follow-on tools.

Das näpfchenförmige Verschlußelement kann aus Metall wie Stahl oder Messing, aber auch aus Kunststoff wie Polyäthylen, Polypropylen, Polyamid oder Polyester hergestellt werden. Es weist einen vorzugsweise kreisscheibenförmigen Boden und einen zylindrischen Mantel auf. Der Boden ist mit der Sollbruchstelle, z.B. sternförmig angeordneten Kerben, versehen. Der Außendurchmesser des zylindrischen Mantels ist so bemessen, daß ein dichter Paßsitz im Bereich des Treibladungspulverraumes der Patronenhülse gewährleistet ist. Das Verschlußelement bewirkt einerseits die geforderte Abdichtung des Treibladungspulverraumes gegenüber Umwelteinflüssen und andererseits die für die Umsetzung des Treibladungspulvers erforderliche Verdämmung. Bevorzugt wird dabei eine Ausführung nach Anspruch 2, welche ein besonders vorteilhaftes "Festkeilen" des Verschlußelementes im Bereich unmittelbar an der konischen Hülsenschulter ermöglicht.The cup-shaped closure element can be made of metal such as steel or brass, but also of plastic such as polyethylene, polypropylene, polyamide or polyester. It has a preferably circular disk-shaped base and a cylindrical jacket. The floor is provided with the predetermined breaking point, for example notches arranged in a star shape. The outer diameter of the cylindrical shell is dimensioned so that a tight fit in the area of the propellant powder space of the cartridge case ge is guaranteed. The closure element, on the one hand, provides the required sealing of the propellant powder space against environmental influences and, on the other hand, the insulation required for the implementation of the propellant powder. Preferred is an embodiment according to claim 2, which enables a particularly advantageous "wedging" of the closure element in the area directly on the conical sleeve shoulder.

Das Verschlußelement wird vom hinteren offenen Ende der Patronenhülse her in diese bis zu seiner vorgegebenen Position eingeführt. Bevorzugt ist es so orientiert, daß es mit dem freien Rand seines zylindrischen Mantels nach hinten weist. Nach dem Einfüllen des Treibladungspulvers in die Patronenhülse wird in deren hinteres offenes Ende das separate metallische Bodenstück eingesetzt und mit dieser durch Kneifen, Kleben oder in anderer geeigneter Weise verbunden. Die für die Herstellung des metallischen Bodenstückes geeigneten Materialien sind verformbare Metalle wie Stahl, Messing, Zink und Aluminium.The closure element is inserted into the predetermined position from the rear open end of the cartridge case. It is preferably oriented in such a way that the free edge of its cylindrical jacket points to the rear. After the propellant powder has been poured into the cartridge case, the separate metallic base piece is inserted into its rear open end and connected to it by pinching, gluing or in another suitable manner. The materials suitable for the production of the metallic base piece are deformable metals such as steel, brass, zinc and aluminum.

Beim Schuß öffnet sich das Verschlußelement an der Sollbruchstelle unter der Wirkung der beim Abbrand des Treibladungspulvers entstehenden Pulvergase, so daß diese austreten und die Waffenfunktion einleiten können. Hierbei wird die Patronenhülse im Bereich der Geschoßnachbildung nicht mehr verformt. Durch die erfindungsgemäße Verlegung der Sollöffnungsstelle in das Patroneninnere wird die Verletzungsgefahr durch den ausgeworfenen Patronenkörper auf ein Minimum reduziert.When the shot is fired, the closure element opens at the predetermined breaking point under the effect of the powder gases formed when the propellant powder burns up, so that they can escape and initiate the weapon function. Here, the cartridge case is no longer deformed in the area of the projectile replica. By moving the target opening point into the interior of the cartridge according to the invention, the risk of injury from the ejected cartridge body is reduced to a minimum.

Alle Waffen, für welche der Einsatz der erfindungsgemäßen Manöverpatrone gedacht ist, sind so konstruiert, daß die Manöverpatrone einschließlich der Geschoßnachbildung einwandfrei aus dem Verschluß der Waffe ausgeworfen werde kann.All weapons, for which the use of the maneuvering cartridge according to the invention is intended, are designed so that the maneuvering cartridge, including the projectile replica, can be ejected properly from the breech of the weapon.

Die zweiteilige Ausführung der Patronenhülse mittels des in die Patronenhülse eingesetzten Bodenstückes bietet in der Ausführungsform mit einer geringeren Hülsenwanddicke und einem schwereren Bodenstück den zusätzlichen Vorteil, daß der Schwerpunkt der Patrone gegenüber den herkömmlichen Übungspatronen weiter nach hinten verschoben ist. Das hat zur Folge, daß beim Auswurf der erfindungsgemäßen übungspatrone aus der Waffe diese schneller ins Trudeln kommt und daher schneller zu Boden fällt. Die Folge davon ist wiederum ein geringeres Verletzungsrisiko beim Übungsschießen.The two-part design of the cartridge case by means of the base piece inserted into the cartridge case offers the additional advantage in the embodiment with a smaller sleeve wall thickness and a heavier base piece that the center of gravity of the cartridge is shifted further back compared to the conventional practice cartridges. The result of this is that when the training cartridge according to the invention is ejected from the weapon, it comes to spin faster and therefore falls to the ground more quickly. The consequence of this in turn is a lower risk of injury during practice shooting.

  • Fig. 2 shows a cross section along the line AB in Fig.1

Die Patronenhülse 1 mit der konischen Hülsenschulter 2 und der hohlen Geschoßnachbildung 3 weist gemäß Fig.1 an deren Spitze die Gasabströmöffnung 4 auf, die frei von nach außen überstehenden scharfkantigen Rändern ist. Das hintere Ende der Geschoßnachbildung an der Manöverpatrone setzt am vorderen Ende des zylindrischen Hülsenhalses, dem Hülsenmund, an, wobei die Übergangszone zwischen Hülsenhals und Geschoßnachbildung mit 3a bezeichnet ist. Der Treibladungspulverraum 5 der Patronenhülse 1 ist nach vorn mittels des Verschlußelementes 6 mit Boden 7 und zylindrischem Mantel 8 dicht abgeschlossen, indem das Verschlußelement unmittelbar vor der Hülsenschulter 2 durch Reibschluß fest gehalten ist. Nach hinten ist der Treibladungspulverraum 5 mittels des separaten Bodenstückes 9 verschlossen, das mit der Patronenhülse 1 über die durch Kneifen erzeugte Riffe 1o verbunden ist. Anschließend wird das Zündhütchen 12 fest in das Bodenstück eingesetzt. Das Zündhütchen dient der späteren Anzündung der Treibladung 13, die sich in der Hülse 5 befindet.The cartridge case 1 with the conical sleeve shoulder 2 and the hollow projectile replica 3 has, according to FIG. 1, the gas outflow opening 4 at its tip, which is free of sharp-edged edges projecting outwards. The rear end of the projectile replica on the maneuver cartridge attaches to the front end of the cylindrical case neck, the case mouth, the transition zone between the case neck and projectile replica being designated by 3a. The propellant powder space 5 of the cartridge case 1 is sealed off at the front by means of the closure element 6 with bottom 7 and cylindrical jacket 8, by the closure element being held firmly in front of the sleeve shoulder 2 by friction. To the rear, the propellant charge powder space 5 is closed by means of the separate base piece 9, which is connected to the cartridge case 1 via the reefs 10 produced by pinching. At closing the primer 12 is firmly inserted into the bottom piece. The primer serves for later ignition of the propellant charge 13, which is located in the sleeve 5.

In Fig.2 sind die Sollbruchstellen 11 des Verschlußelementes 6 zu erkennen, die hier in bekannter Weise als in den Boden 7 des metallischen Verschlußelementes 6 eingeprägte sternförmige Kerben ausgeführt sind. Beim Schuß platzt das Verschlußelement 6 entlang der Sollbruchstellen 11 auf, ohne daß dabei Teil des Verschlußelemente 6 abgerissen werden, welche über die Gasabströmöffnung 4 aus der Patrone und damit auch aus der Waffe austreten könnten.The predetermined breaking points 11 of the closure element 6 can be seen in FIG. 2, which are embodied here in a known manner as star-shaped notches impressed into the base 7 of the metallic closure element 6. When fired, the breech element 6 bursts along the predetermined breaking points 11 without part of the breech element 6 being torn off, which could emerge from the cartridge and thus also from the weapon via the gas outflow opening 4.
