Ein derartiges Flintenlaufgeschoss ist aus der US 4,977,834 A bekannt. Auch DE 38 15 738 C2 , BE 866 822 A , US 4,034,237 A und WO 2004/029539 A beschreiben den Stand der Technik.Such a shotgun projectile is from the US 4,977,834 A known. Also DE 38 15 738 C2 . BE 866 822 A . US 4,034,237 A and WO 2004/029539 A describe the state of the art.

Die der Erfindung zu Grunde liegende Aufgabe liegt darin, eine unter allen Umständen feste Verbindung des Geschosses mit dem Zwischenmittel nach Auslösung des Schusses zu erreichen, wobei vor Auslösung des Schusses das Geschoss mit dem Zwischenmittel nur lose oder gar nicht verbunden ist. Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.The object underlying the invention is to achieve a firm under all circumstances connection of the projectile with the intermediate means after triggering the shot, wherein before triggering the shot the projectile with the intermediate means is only loosely or not connected. According to the invention, this object is solved by the features of claim 1.

Das Geschoss ist auf den Kolben aufgesetzt oder umgekehrt und beim Schuss wird der Kolben in den Freiraum eingeschoben und verkeilt. Zu diesem Einschieben und Verkeilen kann man auch sagen, dass sich der Kolben in das Geschoss festschießt.The bullet is placed on the piston or vice versa and the shot of the piston is inserted into the free space and wedged. At this insertion and wedging one can also say that the piston fires into the projectile.

Des Weiteren zeichnet sich die Erfindung dadurch aus,

  • dass der Freiraum einen auf der Symmetrieachse angeordneten Geschosszapfen aufweist,
  • dass der Kolben eine auf der Symmetrieachse angeordnete Bohrung aufweist,
  • dass der Geschosszapfen und die Bohrung im Durchmesser im wesentlichen aneinander angepasst sind und
  • dass der Geschosszapfen und die Bohrung mit Verkeilelementen ausgestattet sind, die beim Schuss und Einschieben des Kolbens in den Freiraum ein Verkeilen des Kolbens und damit des Zwischenmittels mit dem Geschoss herstellen.
Furthermore, the invention is characterized by
  • the free space has a projectile pin arranged on the axis of symmetry,
  • the piston has a bore arranged on the axis of symmetry,
  • that the projectile pin and the bore in diameter are substantially adapted to each other and
  • that the projectile pin and the bore are equipped with Verkeilelementen that produce a wedging of the piston and thus the intermediate means with the projectile during the shot and insertion of the piston in the free space.

Die Verkeilelemente umfassen dabei erfindungsgemäß eine hohlzylinderförmige Ausbildung des zum Zwischenmittel gewandten Endes des Geschosszapfens, wobei die Unterseite des Geschosszapfens eine nach innen geneigte Schräge aufweist und die Bohrung im Kolben eine am Boden angeordnete Halbkugel aufweist und zusätzlich eine Durchmesserverkleinerung an der Wand der Bohrung oberhalb der Halbkugel angeordnet ist.According to the invention, the wedging elements comprise a hollow-cylindrical formation of the end of the projectile journal facing the intermediate means, the underside of the projectile journal having an inwardly inclined slope and the bore in the piston having a hemisphere arranged on the bottom and additionally a diameter reduction on the wall of the bore above the hemisphere is arranged.

Vorteilhafterweise ist auf dem Außenumfang des Kolbens ein Ring über eine Sollbruchstelle mit dem Kolben verbunden. Bevorzugt ist der Ring einstückig mit dem Kolben ausgebildet.Advantageously, a ring is connected via a predetermined breaking point with the piston on the outer circumference of the piston. Preferably, the ring is formed integrally with the piston.

In bevorzugter Ausführungsform bildet der Ring einen Anschlag für den Geschossboden, d. h. das Geschoss wird auf den Kolben aufgesetzt und liegt mit seinem Geschossboden auf dem Ring auf.In a preferred embodiment, the ring forms a stop for the floor of the storey, d. H. The bullet is placed on the piston and rests on the bullet bottom on the ring.

In einer weiteren erfinduhgsgemäßen Ausgestaltung ist der Ring L-förmig ausgebildet und umgreift mit einem Schenkel das Geschoss nahezu bis zur Geschossspitze. Durch diese Maßnahme wird der Abrieb des Geschosses im Lauf minimiert, da das Geschoss nur im oberen Bereich mit dem Lauf in Berührung kommt.In a further embodiment according to the invention, the ring is L-shaped and surrounds the projectile with a leg almost up to the projectile tip. By this measure, the abrasion of the projectile is minimized during the run, since the bullet comes into contact only with the barrel in the upper area.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass der eine Schenkel eine nach innen gewandte Auskragung aufweist, die in eine entsprechende Ausnehmung im Geschoss eingreift oder umgekehrt.A further embodiment of the invention provides that the one leg has an inwardly facing projection, which engages in a corresponding recess in the projectile or vice versa.

Damit das Geschoss kurz nach dem Schuss in der Patronenhülse bleibt und das Zwischenmittel bzw. der Kolben sich in das Geschoss schieben kann, wird vorgeschlagen, dass die Geschossspitze über eine Schräge mit anschließendem parallel zur Symmetrieachse verlaufendem Absatz in eine zur Symmetrieachse senkrecht verlaufende plane Fläche übergeht, die sich bis zum Außenumfang des Geschosses erstreckt. Auf dieser planen Fläche sitzt die um 180° eingezogene Patronenhülse auf.Thus, the projectile remains in the cartridge case shortly after the shot and the intermediate means or the piston can push into the projectile, it is proposed that the projectile nose over a slope with subsequent parallel to the axis of symmetry extending paragraph in one to the axis of symmetry perpendicular plane surface passes, which extends to the outer periphery of the projectile. On this flat surface is seated by 180 ° retracted cartridge case.

Das Zwischenmittel besteht bevorzugt aus einem Kunststoff und das Geschoss aus einem gut verformbaren Material, insbesondere aus Blei.The intermediate means is preferably made of a plastic and the projectile of a readily deformable material, in particular of lead.

Eine erfindungsgemäße Patrone mit einer Patronenhülse und einer Treibladung zeichnet sich dadurch aus, dass auf der Treibladung ein erfindungsgemäßes Flintenlaufgeschoss mit einem Zwischenmittel aufgesetzt ist.A cartridge according to the invention with a cartridge case and a propellant charge is characterized in that on the propellant charge an inventive shotgun projectile is placed with an intermediate means.

Vorteilhafterweise ist das obere Ende der Patronenhülse um 180° nach innen eingezogen und sitzt auf der planen Fläche auf.Advantageously, the upper end of the cartridge case is retracted 180 ° inwards and sits on the flat surface.

Nachfolgend wird die Erfindung an Hand von Figuren näher erläutert.The invention will be explained in more detail with reference to figures.

Die Figur 1 zeigt in einem Querschnitt durch eine Patrone 20 ein erfindungsgemäßes Flintenlaufgeschoss 1 mit einem Zwischenmittel 2 eingesetzt in einer Patronenhülse 26. Unterhalb des Zwischenmittels 2 ist eine Treibladung 27 angeordnet.The FIG. 1 shows in a cross section through a cartridge 20, a gun barrel 1 according to the invention with an intermediate means 2 inserted in a cartridge case 26. Below the intermediate means 2, a propellant charge 27 is arranged.

Figur 2 zeigt diese Patrone 20 kurz nach der Zündung der Treibladung 27, bevor das Geschoss 1 die Patrone 20 verlassen hat. Der obere als Kolben 21 ausgebildete Teil des Zwischenmittels 2 hat sich in das Geschoss 1 eingeschoben und ist auch dort verkeilt (Beschreibung siehe später). FIG. 2 shows this cartridge 20 shortly after the ignition of the propellant charge 27 before the projectile 1 has left the cartridge 20. The upper part of the intermediate means 2 designed as a piston 21 has pushed into the projectile 1 and is wedged there as well (for a description see later).

Figur 3 zeigt die Patrone 20 nach Aufplatzen des in Schussrichtung gewandten Endes der Patronenhülse 26. FIG. 3 shows the cartridge 20 after bursting the weft-facing end of the cartridge case 26th

Nachfolgend wird die Patrone 20, die in den Figuren 1 bis 3 gezeigt ist, näher erläutert.Subsequently, the cartridge 20, which in the FIGS. 1 to 3 is shown, explained in more detail.

Das Material des Flintenlaufgeschosses 1 besteht aus Pb (Blei) oder einem gut verformbaren Material (siehe Fig. 1). Am oberen Ende des Geschosses 1 ist eine Schräge 3 mit anschließendem Absatz 4 eingebracht. Beim Laborieren, d.h. Umbiegen der Patronenhülse 26 um 180° nach innen zum Festhalten des Geschosses 1, dient die Schräge 3 als Führungshilfe. Der Absatz 4 zentriert die Hülse 26 und die angrenzende zur Symmetrieachse 22 senkrecht verlaufende plane Fläche 5 sorgt für einen festen Sitz des Geschosses 1 in der Patronenhülse 26.The material of the shotgun projectile 1 consists of Pb (lead) or a good deformable material (see Fig. 1 ). At the upper end of the projectile 1 a slope 3 is introduced with subsequent paragraph 4. When working, ie bending the cartridge case 26 by 180 ° inwards for holding the projectile 1, the slope 3 serves as a guide. The paragraph 4 centers the sleeve 26 and the adjacent to the axis of symmetry 22 perpendicular plane surface 5 ensures a firm fit of the projectile 1 in the cartridge case 26th

Somit hat beim Schuss der Absatz 4 mit der planen Fläche 5 den Vorteil, dass die Hülse 26 bis zum Aufschnappen festgehalten wird und dadurch das Geschoss 1 in der Hülse 26 zentriert wird und bis zum Verlassen der Patronenhülse 26 auch zentriert bleibt (verbessertes Trefferbild).Thus, when shot the paragraph 4 with the flat surface 5 has the advantage that the sleeve 26 is held until it snaps and thus the projectile 1 is centered in the sleeve 26 and 26 remains centered until leaving the cartridge case (improved results).

Das Zwischenmittel 2 besteht aus Kunststoff, wobei der vordere Teil als Kolben 21 ausgebildet ist, und hat im hinteren Teil eine Liderungshilfe 6, die einen Gasschlupf der Treibladung 27 bzw. deren Gase nach erfolgter Zündung in Richtung Geschoss 1 verhindert. Im vorderen Bereich hat das Zwischenmittel 2 bzw. der Kolben 21 einen Absatz 7, der das Geschoss 1 mit dem Zwischenmittel 2 zentriert. Der anschließende große Durchmesser (Geschossdurchmesser) des Ringes 8, der in dieser Ausführungsform über eine eingearbeitete Sollbruchstelle 9 einstückig mit dem Kolben 21 verbunden ist, dient als Laborieranschlag beim Aufsetzen des Geschosses 1 auf den Kolben 21 (Geschosssitz - eingezogene Hülse). Die Sollbruchstelle 9 sorgt beim Schuss für einen gleichmäßigen Druckaufbau. Nach dem Abscheren des Ringes 8 durch den sich aufbauenden Druck der Treibgase schiebt sich der Kolben 21 in den Freiraum 10 des Geschosses 1. Der abgescherte Ring 8 wird vom Geschoss 1 auf den Zentrierdurchmesser 11 bzw. dem Kolben 21 nach hinten in Richtung Liderungshilfe 6 gedrückt. Mit den Begriffen "unten" und "hinten" ist in dieser Beschreibung immer das zur Schussrichtung entgegengesetzte Ende verstanden.The intermediate means 2 is made of plastic, wherein the front part is designed as a piston 21, and has in the rear part of a Liderungshilfe 6, which prevents gas slippage of the propellant 27 and their gases after ignition in the direction of projectile 1. In the front region, the intermediate means 2 or the piston 21 has a shoulder 7 which centers the projectile 1 with the intermediate means 2. The subsequent large diameter (projectile diameter) of the ring 8, which is connected in this embodiment via an incorporated predetermined breaking point 9 integral with the piston 21, serves as a laboratory stop when placing the projectile 1 on the piston 21 (seat - retracted sleeve). The predetermined breaking point 9 ensures the shot for a uniform pressure build-up. After shearing of the ring 8 by the pressure building up the propellant gases, the piston 21 pushes into the space 10 of the projectile 1. The sheared ring 8 is pressed from the projectile 1 on the centering diameter 11 and the piston 21 towards the rear in the direction of eyelid 6 , With the terms "bottom" and "back" in this description is always understood the opposite direction to the firing direction end.

Beim Zusammenschieben des Geschosses 1 mit dem Zwischenmittel 2 bzw. den Kolben 21 schiebt sich ein Geschosszapfen 12 mit eingearbeiteter Schräge 13 und Bohrung 14 in die Bohrung 15 im Kolben 21 mit eingearbeiteter Durchmesserverkleinerung 16 und einer Halbkugel 17 am Boden der Bohrung 15. Hat der Kolben 21 einen bestimmten Weg in Richtung Geschoss 1 zurückgelegt, berührt die Schräge 13 die Halbkugel 17. Ab diesen Zeitpunkt bis zum Anschlag der Kolbenoberseite 18a an den Boden 18 des Freiraums 10 (erste Bewegung des Geschosses) wird das Geschossmaterial in den wieder größer werdenden Durchmesser 19 gepresst. So entsteht die gewünschte nicht mehr zu lösende Verbindung. Der Geschosszapfen 12 mit seiner Bohrung 14 und die Bohrung 15 mit der Halbkugel 17 sind auf der Symmetrieachse 22 angeordnet. Der Durchmesser des Geschosszapfens 12 im Bereich der Bohrung 14 ist gegenüber dem Durchmesser der Bohrung 15 im Kolben 21 etwas verringert und entspricht ungefähr dem durch die Durchmesserverkleinerung 16 geschaffenen Durchmesser.When pushing together the projectile 1 with the intermediate means 2 and the piston 21, a bullet pin 12 with incorporated bevel 13 and bore 14 pushes into the bore 15 in the piston 21 with incorporated diameter reduction 16 and a hemisphere 17 at the bottom of the bore 15. Has the piston From this point until the stop of the piston top side 18a against the bottom 18 of the free space 10 (first movement of the projectile), the projectile material becomes the again increasing diameter 19 pressed. This creates the desired connection that can no longer be solved. The projectile pin 12 with its bore 14 and the bore 15 with the hemisphere 17 are arranged on the axis of symmetry 22. The diameter of the bullet pin 12 in the region of the bore 14 is slightly reduced compared to the diameter of the bore 15 in the piston 21 and corresponds approximately to the diameter created by the diameter reduction 16.

Die Höhe der festen Verbindung zwischen Kolben 21 und Ring 8 bestimmt bei welchem Gasdruck der Abriss des Ringes 8 erfolgt. Der Druckaufbau im Pulverraum, wo sich die Treibladung 27 befindet, bestimmt den Abriss des Ringes 8 an der Sollbruchstelle 9 und gibt somit das Zwischenmittel 2 mit dem Kolben 21 frei. Der Ring 8 kann sich auf dem Durchmesser 11 zentriert nach hinten bewegen. Der Kolben 21 schiebt sich in das Geschoss 1, dass durch die am oberen Ende um 180° eingezogene Hülse 26 festgehalten wird. Nach einem bestimmten Weg trifft die Schräge 13 auf die Halbkugel 17 und drückt das ab der Schräge 13 befindliche Material in den wieder größer werdenden Durchmesser 19. So entsteht eine feste Verbindung zwischen Geschoss 1 und Kolben 21. Stoßen die beiden Flächen 18 und 18a formschlüssig aneinander, setzt sich das Geschoss 1 gegen die Kraft der eingezogenen Hülse 26 in Bewegung.The height of the fixed connection between the piston 21 and ring 8 determines at which gas pressure the demolition of the ring 8 takes place. The pressure build-up in the powder chamber, where the propellant 27 is located, determines the demolition of the ring 8 at the predetermined breaking point 9 and thus releases the intermediate means 2 with the piston 21. The ring 8 can move centered on the diameter 11 to move backwards. The piston 21 pushes into the projectile 1 that is held by the retracted at the upper end by 180 ° sleeve 26. After a certain way, the slope 13 meets the hemisphere 17 and presses the material located from the slope 13 in the again increasing diameter 19. Thus, a firm connection between the projectile 1 and piston 21 is formed. The two surfaces 18 and 18a abut one another positively , the projectile 1 is against the force of the retracted sleeve 26 in motion.

Dabei schält sich die Hülse 26 durch den Absatz 4 und der planen Fläche 5 nach oben und zentriert und stabilisiert zusätzlich das Geschoss 1 in der Hülse 26 bis dieses die Hülse 26 verlässt. Dies ist die Voraussetzung für einen stabilen Flug im und außerhalb des Laufes. Aber erst das aufeinander abgestimmte System garantiert die erwünschte Präzision.In this case, the sleeve peels 26 through the paragraph 4 and the flat surface 5 upwards and centered and additionally stabilizes the projectile 1 in the sleeve 26 bis this leaves the sleeve 26. This is the prerequisite for a stable flight in and out of the race. But only the coordinated system guarantees the desired precision.

Vorteile der Erfindung sind:

  • Zentriertes und stabilisiertes Geschoss 1 in der Hülse 26 durch den Absatz 4
  • Stabiles Zwischenmittel 2 aus Kunststoff
  • Gleichmäßiger Druckaufbau durch die Sollbruchstelle 9 am Ring 8
  • Zentrierung des Zwischenmittels 2 und des Geschosses 1
  • Zusätzliche Stabilisierung durch den abgescherten Ring 8
  • Feste Verbindung zwischen Geschoss 1 und Zwischenmittel 2 bzw. Kolben 21 (keine Abgangsfehler durch Lösen des Zwischenmittels 2 vom Geschoss 1).
Advantages of the invention are:
  • Centered and stabilized projectile 1 in the sleeve 26 through the paragraph 4th
  • Stable intermediate means 2 made of plastic
  • Uniform pressure build-up by the predetermined breaking point 9 on the ring. 8
  • Centering of the intermediate means 2 and the projectile. 1
  • Additional stabilization by the sheared ring 8
  • Fixed connection between projectile 1 and intermediate means 2 and piston 21 (no departure error by releasing the intermediate means 2 from the projectile 1).

Figur 4 zeigt eine Ausführungsform bei der der Ring 8 L-förmig ausgebildet ist und mit einem Schenkel 8a das Geschoss 1 nahezu bis zur Geschossspitze umgreift. Durch diese Maßnahme wird der Pb-Abrieb im Lauf minimiert, da das Geschoss 1 nur im oberen Bereich mit dem Lauf in Berührung kommt. FIG. 4 shows an embodiment in which the ring 8 is L-shaped and with a leg 8a, the projectile 1 almost encompasses up to the projectile nose. By this measure, the Pb abrasion in the barrel is minimized because the projectile 1 comes into contact only with the barrel in the upper area.
