Description

Die Erfindung bezieht sich auf eine Patrone mit Flintenlaufgeschoß nach dem Oberbegriff des Anspruches 1. Eine derartige Patrone gehört zum Stand der Technik gemäß Artikel 54(2) EPÜ.The invention relates to a cartridge with a shotgun barrel according to the preamble of claim 1. Such a cartridge belongs to the prior art according to Article 54 (2) EPC.

Die DE-PS 3 241 149 zeigt eine Patrone mit Flintenlaufgeschoß und einem Bleikopf mit Spitze sowie einem Pfropfen aus elastischem Material, der mit dem Bleikopf über eine Steckverbindung verbunden ist, welche einen hülsenförmigen Ansatz im Inneren des zylindrischen Bleikopfes aufweist. Dem Bleikopf ist dabei ein Pfropfen aus elastischem Material mit einem topfförmigen Teil zugeordnet, an welchen ein in Schußrichtung weisender Zapfen angeformt ist, der in den hülsenförmigen Ansatz des Bleikopfes eingreift. Konzentrisch zu diesem Zapfen ist ein Keilring angeordnet, der in eine keilringnutförmige Aussparung im Bleikopf eingreift. Die aus diesen Teilen gebildete Steckverbindung füllt den Geschoßkopf insofern nicht ganz aus, als zwischen der Stirnfläche des Keilringes und des Zapfens einerseits und der Stirnfläche der zugeordneten Aussparungen im Bleikopf andererseits in der Ladestellung der Patrone ein Zwischenraum freibleibt.DE-PS 3 241 149 shows a cartridge with a shotgun barrel and a lead head with a tip and a plug made of elastic material which is connected to the lead head via a plug-in connection which has a sleeve-shaped projection in the interior of the cylindrical lead head. The lead head is assigned a plug made of elastic material with a cup-shaped part, on which a pin pointing in the weft direction is formed, which engages in the sleeve-shaped extension of the lead head. A wedge ring is arranged concentrically to this pin and engages in a wedge-ring-shaped recess in the lead head. The plug connection formed from these parts does not completely fill the projectile head to the extent that a gap remains free between the end face of the wedge ring and the pin on the one hand and the end face of the associated recesses in the lead head on the other hand in the loading position of the cartridge.

Die gleichen Überlegungen gelten sinngemäß auch für die Patronen mit Flintenlaufgeschoß nach den beiden DE-OS 2 615 859 und 2 929 628. Nach der Zündung der Treibladung versucht der Pfropfen, die im Bleikopf befindlichen freien Kammern zu verkleinern. Dabei hängt der Umfang der Räume von der Herstellungsgenauigkeit der miteinander in Eingriff stehenden Teile ab. Man hat es hiernach bei der Konstruktion einer derartigen Patrone mit Flintenlaufgeschoß auf keinen Fall in der Hand, von vorn herein festzulegen, ob und in welchem Umfang diese freien Räume nach der Zündung der Treibladung vorhanden sind. Das heißt mit anderen Worten, daß wegen der möglichen Relativbewegung der miteinander in Eingriff stehenden Teile nach der Zündung der Treibladung der Schwerpunkt des Geschosses nicht genau fixierbar ist. Damit kann aber auch die Flugweite nicht von vorn herein festgelegt werden, da diese in erheblichem Umfang von der Lage des Schwerpunktes des Geschosses während des Fluges abhängt.The same considerations apply mutatis mutandis to the cartridges with a shotgun barrel according to both DE-OS 2 615 859 and 2 929 628. After the propellant has been ignited, the plug tries to reduce the size of the free chambers in the lead head. The scope of the rooms depends on the manufacturing accuracy of the parts that are in engagement with one another. According to this, when designing such a cartridge with a shotgun barrel, it is by no means in your hand to determine from the start whether and to what extent these free spaces are available after the propellant has been ignited. In other words, because of the possible relative movement of the parts in engagement with each other after the propellant has been ignited, the center of gravity of the projectile cannot be fixed exactly. However, this also means that the flight distance cannot be determined from the outset, since this depends to a considerable extent on the position of the center of gravity of the projectile during the flight.

Bei der Anordnung nach der DE-PS 3 241 149 kommt noch erschwerend hinzu, daß der Zapfen (9b) in den als dünne Platte (10a) ausgebildeten Teil eingreift, deren Lage sich gegenüber diesem Zapfen (9b) bei der Zündung nach Maßgabe der jeweilgen Fertigungsungenauigkeiten von Fall zu Fall ändert. Hierdurch wird die Treffsicherheit des Geschosses beeinträchtigt.In the arrangement according to DE-PS 3 241 149 is further aggravated that the pin (9b) engages in the part formed as a thin plate (10a), the position of which relative to this pin (9b) during ignition according to the respective Manufacturing inaccuracies change from case to case. This affects the accuracy of the projectile.

Ein weiterer Nachteil der Patrone mit Flintenlaufgeschoß nach der DE-PS 3 241 149 ist darin zu erblicken, daß nach der Zündung der Treibladung der Pfropfen versucht, die vorerwähnten freien Räume auzufüllen, was zwangsläufig radiale Deformationen des vergleichsweise weichen Bleikopfes zur Folge hat.Another disadvantage of the cartridge with a shotgun barrel according to DE-PS 3 241 149 can be seen in the fact that after the propellant has been ignited, the plug tries to fill up the aforementioned free spaces, which inevitably results in radial deformations of the comparatively soft lead head.

Die Erfindung geht nun von der Überlegung aus, diese bekannten Patronen mit Flintenlaufgeschoß so zu verbessern, daß unabhängig von den jeweiligen herstellungsbedingten Ungenauigkeiten der das Geschoß bildenden Teile der Schwerpunkt desselben nach der Zündung der Treibladung stets an der gleichen Stelle zu liegen kommt.The invention is based on the idea of improving these known cartridges with a shotgun barrel so that regardless of the respective manufacturing-related inaccuracies of the parts forming the projectile, the center of gravity of the bullet always comes to the same place after the propellant has been ignited.

Diese Aufgabe wird bei der Patrone mit Flintenlaufgeschoß nach dem Oberbegriff des neuen Anspruches 1 durch die Kombination folgender Merkmale gelöst:

  • a) Der Zapfen (3a) füllt eine im Bleikopf (1) angeordnete Aussparung (1 a) vollständig aus.
  • b) Der Mittelteil (4) ist mit dem Unterteil (5) über eine Sollbruchstelle (6) verbunden.
  • c) Am Mittelteil (4) ist ein als Auflage während des Fluges des Geschosses für den Unterteil (5) dienender Ansatz (4a) vorgesehen.
  • d) Der Abstand (a) zwischen der Abschlußfläche (3b) und dem Ansatz (4a) ist gleich der Dicke (D) des Unterteiles (5).
This object is achieved in the cartridge with a shotgun barrel according to the preamble of the new claim 1 by the combination of the following features:
  • a) The pin (3a) completely fills a recess (1 a) arranged in the lead head (1).
  • b) The middle part (4) is connected to the lower part (5) via a predetermined breaking point (6).
  • c) On the middle part (4) an attachment (4a) serving as a support during the flight of the projectile for the lower part (5) is provided.
  • d) The distance (a) between the end face (3b) and the shoulder (4a) is equal to the thickness (D) of the lower part (5).

Durch das Merkmal a) wird sichergestellt, daß vor und damit zwangsläufig auch nach dem Abschuß die Verbindung zwischen dem Zapfen (3a) einerseits und dem Bleikopf (1) andererseits spielfrei ist.Characteristic a) ensures that the connection between the pin (3a) on the one hand and the lead head (1) on the other hand is free of play before and therefore inevitably even after firing.

Durch die Merkmalskombination b)-d) wird erreicht, daß nach dem Zündvorgang der Unterteil (5) zwischen der Abschlußfläche (3b) und dem Ansatz (4a) spielfrei und fixiert zu liegen kommt. Auf diese Weise ist jedwede Aleatorik hinsichtlich der Lage der Teile (1, 3a und 5) namentlich nach der Zündung der Treibladung ausgeschlossen.The combination of features b) -d) ensures that after the ignition process the lower part (5) comes to lie free of play and fixed between the end face (3b) and the shoulder (4a). In this way, any aleatoric with regard to the position of the parts (1, 3a and 5), especially after the propellant charge is ignited, is excluded.

Der Konstrukteur hat es hiernach von vorn herein in der Hand, aufgrund der einzelnen Teile vor dem Abschuß - wie sie z.B. die Fig. 5 der Zeichnung zeigt - den Schwerpunkt des den Flintenlauf verlassenden Geschosses genau zu ermitteln und damit die Flugweite bei entsprechender Dosierung der Pulverladung exakt festzulegen. Hierin liegen die entscheidenden Vorteile der Erfindung gegenüber dem einschlägigen Stand der Technik.The designer then has it in hand from the start, due to the individual parts before firing - as they e.g. 5 of the drawing shows - to determine exactly the center of gravity of the projectile leaving the shotgun barrel and thus to precisely determine the flight range with appropriate metering of the powder charge. Herein lie the decisive advantages of the invention over the relevant prior art.

Further features of the invention emerge from the following description, the subclaims and the drawing, in which show in a purely schematic manner:
  • FIG. 1 shows a view of the lead head of the shotgun barrel of the cartridge according to the invention,
  • FIG. 2 shows a vertical section through the lead head of the shotgun barrel of the cartridge according to the invention,
  • FIG. 3 shows a top view of the arrangement according to FIG. 2,
  • FIG. 4 shows a vertical section through the plug of the cartridge with a shotgun barrel according to the invention,
  • 5 shows a vertical section through the cartridge with a shotgun barrel according to the invention in the loading position,
  • Figures 6 and 7 a partial section through the lead head and the plug of the cartridge with a shotgun barrel according to the invention during and after firing.

Mit 1 (Figuren 1 - 3) ist der Bleikopf des Geschosses bezeichnet, dessen zylinderförmige Teil mit schräg zur Längsachse verlaufenden Rippen 2 versehen ist.1 (FIGS. 1 to 3) denotes the lead head of the projectile, the cylindrical part of which is provided with ribs 2 which run obliquely to the longitudinal axis.

Die Figur 4 der Zeichnung zeigt einen senkrechten Schnitt durch einen aus einem elastischen Material, z. B. Kunststoff, bestehenden Pfropfen, der aus einem Oberteil 3, einem stangenförmigen Mittelteil 4 und einem flachkolbenartigen Unterteil 5 besteht. Der flachkolbenartige Unterteil 5 ist mit dem stangenförmigen Mittelteil 4 über eine Sollbruchstelle 6 verbunden, deren Einzelheiten im folgenden noch beschrieben sind.Figure 4 of the drawing shows a vertical section through a made of an elastic material, for. B. plastic, existing plug, which consists of an upper part 3, a rod-shaped central part 4 and a flat piston-like lower part 5. The flat piston-like lower part 5 is connected to the rod-shaped central part 4 via a predetermined breaking point 6, the details of which are described below.

Wie namentlich die Figur 4 deutlich zeigt, weist der Oberteil 3 des Pfropfens einen zylinderförmigen Zapfen 3a auf, der in eine sacklochartige Aussparung 1 a im Bleikopf 1 formschlüssig und ohne jedwede Konizität eingreift. Dies machen die Figuren 5 - 7 der Zeichnung besonders deutlich, bei welchen die Wandungen des zylinderförmigen Zapfens 3a auf den entsprechenden Wandungen der sacklochartigen Aussparung 1a vollständig satt aufliegen, ir7 gendwelche Zwischenräume zwischen diesen Teilen auf alle Fälle also vermieden sind. Dies stellt ein wesentliches Merkmal der Erfindung dar.As the figure 4 shows clearly, the upper part 3 of the plug has a cylindrical pin 3a which engages in a blind hole-like recess 1 a in the lead head 1 in a form-fitting manner and without any conicity. This make the figures 5-7 of the drawings particularly clear in which the walls of the cylindrical peg 3a on the corresponding walls of the blind hole-like recess 1a completely tightly against, are ir 7 quietly that gaps between these parts in any case thus avoided. This is an essential feature of the invention.

Durch den formschlüssigen Eingriff des zylinderförmigen Zapfens 3a in die sacklochartige Aussparung 1a wird eine formschlüssige Steckverbin dung verwirklicht, wobei der Zusammenhalt dieser beiden Teile 1 und 3 - 5 ggf. noch dadurch verbessert werden kann, daß der zylinderförmige Zapfen 3a gegenüber der sacklochartigen Aussparung 1a ein gewisses Übermaß aufweist. Um ein Lösen des Bleikopfes 1 von dem Pfropfen auch während des Fluges des Geschosses mit Sicherheit zu vermeiden, kann der Bleikopf 1 mit dem zylinderförmigen Zapfen 3a des Oberteiles 3 des Pfropfens zusätzlich mit zumindest einem Körnerschlag 7 verbunden sein. Dabei dringt das weiche Material des Bleikopfes 1 an der Stelle dieses Körnerschlages 7 in den zylinderförmigen Zapfen 3a des Pfropfens ein.By the positive engagement of the cylindrical pin 3a in the blind hole-like recess 1a, a positive plug connection is realized, the cohesion of these two parts 1 and 3 - 5 possibly being improved by the fact that the cylindrical pin 3a is opposite the blind hole-like recess 1a has some excess. In order to reliably prevent the lead head 1 from becoming detached from the plug even while the projectile is in flight, the lead head 1 can additionally be connected to the cylindrical pin 3a of the upper part 3 of the plug with at least one punch 7. The soft material of the lead head 1 penetrates into the cylindrical pin 3a of the plug at the location of this punch 7.

Nach einer sehr zweckmäßigen Ausführungsform der Erfindung sind der Mittelteil 4 und der Unterteil 5 des Pfropfens im Querschnitt kreisförmig. Im Unterteil 5 ist eine Ringfuge 5a vorgesehen, deren Durchmesser d gleich ist dem Durchmesser d' des Mittelteiles 4. Wie namentlich die Figuren 4 und 5 zeigen, weist die Öffnung der Ringfuge 5a in die dem Oberteil 3 abgewandte Richtung, also in der Zeichnung nach unten und wird dabei von einer Lippe 5b umgeben.According to a very expedient embodiment of the invention, the central part 4 and the lower part 5 of the plug are circular in cross section. In the lower part 5 there is an annular joint 5a, the diameter d of which is equal to the diameter d 'of the central part 4. As is particularly shown in FIGS. 4 and 5, the opening of the annular joint 5a points in the direction facing away from the upper part 3, that is to say in the drawing below and is surrounded by a lip 5b.

Die mit 6 bezeichnete Sollbruchstelle, die beim Abschuß auf Abscherung beansprucht wird, ist die Mantelfläche zwischen dem in den Unterteil 5 eindringenden Teil des Mittelteiles 4 und dem diesen Teil umgebenden Teil des Unterteiles 5.The predetermined breaking point denoted by 6, which is subjected to shearing when fired, is the lateral surface between the part of the middle part 4 penetrating into the lower part 5 and the part of the lower part 5 surrounding this part.

Der Oberteil 3 des Pfropfens wird von einer unteren Abschlußfläche 3b begrenzt, in welche der Mittelteil 4 übergeht. Dabei ist am Mittelteil 4 ein als Auf lage während des Fluges des Geschosses für den Unterteil 5 dienender Ansatz 4a vorgesehen, wobei der Abstand a zwischen diesem und der Abschlußfläche 3b gleich ist der Dicke D des Unterteiles 5. Zweckmäßig bildet der Ansatz 4a einen Bestandteil des Mittelteiles 4, besteht also aus dem gleichen Material, nämlich aus elastischem Kunststoff.The upper part 3 of the plug is delimited by a lower end face 3b, into which the middle part 4 merges. It is provided on the middle part 4 as a position during the flight of the projectile for the lower part 5 approach 4a, the distance a between this and the end face 3b being equal to the thickness D of the lower part 5. Appropriately, the approach 4a forms part of the Middle part 4, so consists of the same material, namely elastic plastic.

In Figur 5 der Zeichnung ist mit 8 die Patronenhülse bezeichnet, in deren unterem Teil die Treibladung 9 angeordnet ist. Zwischen dem Unterteil 5 des Pfropfens und der Treibladung 9 ist ein Zwischenstück 10 angeordnet. Hierdurch kann das zu große Pulvervolumen in langen Hülsen ggf. reduziert werden. In diesem Zwischenstück 10 ist eine zentrale, zylinderförmige Kammer 11 vorgesehen, deren Durchmesser 12 größer ist als der Durchmesser d' des Mittelteiles 4 des Pfropfens. Hierdurch kann sich der Mittelteil 4 des Pfropfens bei der Schußentwicklung ohne Verformung und Störung in die Kammer 11 hineinbewegen. Die Kammern ist mit dem die Treibladung 9 aufnehmenden Teil der Patronenhülse 8 über eine Bohrung 13 verbunden, welche so bemessen ist, daß zwar keine Pulverteilchen, wohl aber hochgespannte Pulvergase während der Dauer der Schu ßentwicklung in die Kammer 11 eindringen können. Dies führt dazu, daß - nachdem das Geschoß die Laufmündung verlassen hat - im Außenbereich der normale Luftdruck herrscht, während in der Kammer 11 des Zwischenstückes 10 ein Überdruck besteht, welcher eine störungsfreie Trennung des Zwischenstückes 10 von dem das Ziel erreichenden Teilen, also dem Bleikopf 1 und dem Pfropfen, sicherstellt.In Figure 5 of the drawing, 8 denotes the cartridge case, in whose lower part the propellant charge 9 is arranged. An intermediate piece 10 is arranged between the lower part 5 of the plug and the propellant charge 9. As a result, the excessively large powder volume in long sleeves can be reduced if necessary. In this intermediate piece 10, a central, cylindrical chamber 11 is provided, the diameter 12 of which is larger than the diameter d 'of the central part 4 of the plug. As a result, the middle part 4 of the plug can move into the chamber 11 during the weft development without deformation and interference. The chambers is connected to the propellant charge 9 receiving part of the cartridge case 8 via a bore 13 which is dimensioned such that no powder particles, but highly stressed powder gases can penetrate into the chamber 11 during the duration of the shot. This leads to the fact that - after the projectile has left the barrel muzzle - there is normal atmospheric pressure outside, while in the chamber 11 of the intermediate piece 10 there is an overpressure, which ensures a trouble-free separation of the intermediate piece 10 from the parts reaching the target, i.e. the lead head 1 and the grafting.

Die Arbeitsweise der Patrone mit Flintenlaufgeschoß ist die folgende:The operation of the shotgun cartridge is as follows:

In der Ladestellung - also vor der Entzündung der Treibladung 9 - nehmen die einzelnen Teile der Patrone die aus Figur 5 der Zeichnung ersichtliche Lage ein. Wenn die Treibladung 9 zündet, dann bewirkt der auf den Unterteil 4 des Pfropfens zur Einwirkung gelangende Gasdruck ein Ansprechen der Sollbruchstelle 6 mit der Folge, daß sich der Unterteil 5 längs des Mittelteiles 4 des Pfropfens nach oben, also in Richtung der Laufmündung, bewegt. Dabei überfährt der Mittelteil 4 den Ansatz 4a, der in der Endstellung - in welcher sich der Unterteil 5 gegen die Abschlußfläche 3b des Oberteiles 3a des Pfropfens anlegt - den Unterteil 5 untergreift. Der Bleikopf 1 und der Pfropfen bilden nunmehr eine untrennbare Einheit und bewegen sich auf das anvisierte Ziel, während das eventuell verwendete Zwischenstück 10 kurz hinter der Mündung des Laufes ausgeworfen wird. Die Figur 7 macht die kompakte Einheit der das Ziel erreichenden Teile sowie die außerordentlich günstige Lage des Schwerpunktes dieser Teile besonders deutlich.In the charging position - that is, before the propellant 9 is ignited - the individual parts of the cartridge assume the position shown in FIG. 5 of the drawing. When the propellant charge 9 ignites, the gas pressure acting on the lower part 4 of the plug causes the predetermined breaking point 6 to respond, with the result that the lower part 5 moves upwards along the central part 4 of the plug, that is to say in the direction of the barrel mouth. The middle part 4 passes over the shoulder 4a, which in the end position - in which the lower part 5 bears against the end face 3b of the upper part 3a of the plug - engages under the lower part 5. The lead head 1 and the plug now form an inseparable unit and move towards the targeted target, while the intermediate piece 10 which may be used is ejected shortly behind the mouth of the barrel. FIG. 7 makes the compact unit of the parts reaching the target and the extremely favorable location of the center of gravity of these parts particularly clear.
