Definitions

  • the invention relates to a gas pressure weapon system according to the preamble of claim 1.
  • Such a gas pressure weapon system is known, for example, from EP-A-0 189 974.
  • the projectile used in the known gas pressure weapon system has an essentially cylindrical head section and an apron section in the form of an annular flange at its rear end in the weft direction.
  • a cartridge filled with compressed gas Arranged behind the projectile in the shot preparation position is a cartridge filled with compressed gas, which can be reused after a shot, ie refilled with compressed gas. So that this cartridge can be easily inserted into and removed from the cartridge receiving chamber, sufficient play must be present between the outer peripheral surface of the filled cartridge and the inner peripheral surface of the cartridge receiving chamber. Separate sealants are therefore required to prevent gas from escaping at the muzzle end of the barrel in the event of a shot.
  • the ammunition for gas pressure weapons viewed in a direction perpendicular to the axial direction of the barrel, usually has a maximum outer diameter which is slightly oversized compared to the inner diameter of the barrel. This excess must be reduced when a bullet is inserted into the barrel - the bullet is calibrated. This is to ensure that the projectile seals the barrel towards the muzzle in its shot preparation position, so that when the shot is fired, the full gas pressure contributes to the acceleration of the projectile and a part of the gas cannot escape past the projectile.
  • the hit position of the projectile depends crucially on how the projectile was introduced into the barrel. For example, different shooters also achieve different shots when the weapon is firmly adjusted to the target, the trigger is actuated automatically and only the ammunition is inserted by hand. Even a single shooter will get different shots depending on whether he carefully or carelessly inserts the ammunition into the barrel. The shooters find this extremely uncomfortable.
  • EP-A-0 538 733 is prior art in accordance with Art. 54 (3) EPC and relates to a compressed gas cartridge suitable for use with gas pressure weapons, an expansion chamber being formed in the interior of the cartridge. Shot down using this cartridge and a diabolo round. This document deals in particular with the internal structure of the cartridge and with the composition of the propellant set.
  • US-A-3 474 560 and US-A-1 817 273 relate to firearms.
  • the practice ammunition includes a projectile, as is customary for gas pressure weapons, and which is glued to a security cartridge. In the shot preparation position, the projectile only protrudes slightly with its head part into the barrel channel.
  • the cartridge has a head part made of paper, the outer circumference of which is arranged at a clear distance from the inner circumferential surface of the cartridge receiving chamber.
  • a projectile is inserted into the feeder in preparation for a shot.
  • This projectile is designed in such a way that it seals the barrel channel towards the projectile exit end.
  • a pressure piston device is tensioned, as is known from a conventional gas pressure weapon. The pressure piston device is triggered when the shot is fired. Due to the pressure that builds up, a propellant charge, which is arranged in a hollow cylinder formed in one piece with the projectile and open at its end facing away from the projectile outlet end, ignites according to the "diesel effect". The sealing effect of the projectile ensures that the propellant charge ignites safely.
  • the projectile is only accelerated towards the end of the projectile by the compressed gas released by the propellant charge.
  • a specially designed projectile must be used in the known weapon system.
  • this is often undesirable or not possible with gas pressure weapons.
  • only certain projectiles may be used in the area of sports shooters.
  • a cartridge receiving chamber is thus provided in the region of the feed of the barrel channel in axial alignment with the barrel channel, which holds a pressurized gas generating cartridge that can be inserted separately from the projectile and can be used for one shot each, in a position behind the projectile that is in the preparation position for the shot, this pressurized gas generating cartridge containing the propellant set. Since the projectile and the cartridge are provided according to the invention as separate parts, the projectile and then the cartridge are first introduced into the cartridge receiving chamber when the weapon system is loaded.
  • the rear end region of the projectile When the projectile is inserted into the barrel channel, the rear end region of the projectile is narrowed in diameter, so that the outside diameter of the projectile in the preparation position is adapted to the inside diameter of the barrel channel, ie the projectile is calibrated when it is inserted into the barrel channel.
  • the cartridge has a cartridge housing.Furthermore, mutually facing end parts of the projectile and the cartridge housing are for mutual contact along a ring surrounding the axis formed, a gas receiving space is formed between the mutually facing end parts within this ring and wherein the end part of the cartridge housing has a gas outlet opening opening into this gas receiving space.
  • the aforementioned gas receiving space is formed by a hollow of the projectile at its rear end and a tapered projection of the cartridge housing at its front end, the hollow and the limit the tapered projection between them the gas receiving space.
  • a good sealing effect is achieved by both the cavity and the protrusion being bounded by a conical surface.
  • the outside diameter of the cartridge is matched to the inside diameter of the cartridge receiving chamber in such a way that the cartridge moves easily into the Cartridge receiving chamber can be inserted, and the cartridge is at least partially made of plastic so expandable that it is gas-tight against the inner peripheral surface of the cartridge receiving chamber under the action of a gas pressure building up inside.
  • a separate sealing element can thus be dispensed with.
  • This also enables the production of a particularly inexpensive and light weapon. It only has to be the barrel of the weapon be manufactured with high precision. All other components of the weapon can be made of light materials, for example plastic or aluminum, and do not have to be machined with high precision.
  • the conical surfaces of the cavity and of the projection have conical angles that match at least over part of their axial lengths.
  • the inside diameter of the cartridge receiving chamber slightly exceed the maximum diameter of the projectile, so that the projectile can be inserted easily into the cartridge receiving chamber, and that the inside diameter of the barrel channel has a smaller value than the inside diameter of the cartridge receiving chamber , the projectile being insertable through the cartridge into the barrel channel when the cartridge is inserted into the cartridge receiving chamber.
  • the reproducible calibration of the projectiles can be supported by designing the transition between the cartridge receiving chamber and the barrel channel as a conical transition.
  • the barrel channel adjacent to the cartridge receiving chamber has a smooth cylindrical section and this smooth cylindrical section to the projectile exit end of the barrel channel has a section provided with trains, with a front end region of the projectile from the train section and a rear end region in a shot preparation position of the projectile are taken up by the smooth cylindrical section, the calibration of the projectile and the insertion of the projectile into the section of the running channel provided with trains can be carried out in succession, so that the forces exerted on the projectile can be kept small, which reduces the reproducibility of the calibration further improved.
  • the bottom surface of the trains align with the inner peripheral surface of the smooth cylindrical section and that lying between the trains fields of the section of the running channel provided with trains project slightly radially inwards relative to the smooth cylindrical section and merge into the smooth cylindrical section via conical transition surfaces.
  • the outer diameter of the front projectile section is smaller than the diameter defined by the fields of the section of the running channel provided with trains, it can be ensured that all deformations of the projectile required for calibrating and inserting the projectile into the section provided with trains at the rear section be made and the projectile thus moves more evenly when fired.

  • the gas which develops as a result of the ignition flows into an expansion chamber 20b of the cartridge, which serves to build up and homogenize the pressure.
  • the compressed gas occurs at a preferably tapered head part 20c Cartridge 20 out of a nozzle 20f and accelerates a projectile or projectile 24 arranged in the barrel 12 towards the mouth of the barrel 12.
  • the nozzle 20f can have a diameter of approximately 2 mm, for example.
  • a loading flap 28 pivotably mounted on the housing 14 at 26 is first pivoted in the direction of the arrow A (see FIGS. 1 and 2).
  • a locking slide 30 is mounted in a receptacle 14a which is essentially parallel to the axial direction of the barrel 12 and can be pushed back and forth in the direction of the arrows B and B '.
  • the locking slide 30 is operatively connected to the loading hatch 28 via an articulated lever 32 and two bolts 32a and 32b so that the locking slide 30 when the loading hatch 28 is opened, i. when pivoting the loading flap in the direction of arrow A, in the receptacle 14a in the direction of arrow B, i.e. away from barrel 12.

  • a trigger system 36 of the weapon 10 is automatically cocked when the loading flap is opened.
  • the trigger system 36 comprises a striker 38 pivotably mounted on the housing 14 at 38a, a striker 40 and a trigger 42 pivotably mounted on the housing at 42a.

For this purpose, an operator actuates a loading slide button 52a arranged on the loading slide 52, which can best be seen in FIG. 5. If the loading slide 52 is in its lower position shown in FIG. 2, the compression spring (not shown) of the receptacle 48 displaces the cartridges 20 received in the receptacle 48 by one cartridge length in the direction of the transport device 50.

Abstract

A compressed gas weapon (10) is configured in the breech portion (18) of its barrel (12) to accommodate a projectile (24) in a position of readiness to fire and to reproducibly caliber the projectile (24) in the process of conveying it into the position of readiness to fire.

Description

Die Erfindung betrifft ein Gasdruck-Waffensystem gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a gas pressure weapon system according to the preamble of claim 1.

Ein derartiges Gasdruck-Waffensystem ist bspw. aus der EP-A-0 189 974 bekannt. Das bei dem bekannten Gasdruck-Waffensystem verwendete Projektil weist einen im wesentlichen zylinderförmig ausgebildeten Kopfabschnitt und an seinem in Schußrichtung hinteren Ende einen Schürzenabschnitt in Form eines Ringflansches auf. Hinter dem Projektil ist in der Schußvorbereitungsstellung eine mit Druckgas gefüllte Kartusche angeordnet, welche nach einem Schuß wiederverwendet, d.h. erneut mit Druckgas gefüllt werden kann. Damit diese Kartusche in die Kartuschenaufnahmekammer leicht eingeführt und aus dieser auch wieder leicht entnommen werden kann, muß zwischen der Außenumfangsfläche der gefüllten Kartusche und der Innenumfangsfläche der Kartuschenaufnahmekammer ausreichend Spiel vorhanden sein. Daher sind gesonderte Dichtungsmittel erforderlich, um bei einem Schuß den Austritt von Gas am mündungsfernen Ende des Laufs zu verhindern.Such a gas pressure weapon system is known, for example, from EP-A-0 189 974. The projectile used in the known gas pressure weapon system has an essentially cylindrical head section and an apron section in the form of an annular flange at its rear end in the weft direction. Arranged behind the projectile in the shot preparation position is a cartridge filled with compressed gas, which can be reused after a shot, ie refilled with compressed gas. So that this cartridge can be easily inserted into and removed from the cartridge receiving chamber, sufficient play must be present between the outer peripheral surface of the filled cartridge and the inner peripheral surface of the cartridge receiving chamber. Separate sealants are therefore required to prevent gas from escaping at the muzzle end of the barrel in the event of a shot.

Ein weiteres Problem ist darin zu sehen, daß die Munition für Gasdruckwaffen, in einer senkrecht zur Achsrichtung des Laufs verlaufenden Richtung gesehen, üblicherweise einen maximalen Außendurchmesser aufweist, der gegenüber dem Innendurchmesser des Laufs leicht mit Übermaß bemessen ist. Dieses Übermaß muß beim Einbringen eines Geschosses in den Lauf abgebaut werden - das Geschoß wird kalibriert. Hierdurch soll gewährleistet werden, daß das Geschoß in seiner Schußvorbereitungsstellung den Lauf zur Mündung hin abdichtet, so daß beim Schuß der volle Gasdruck zur Beschleunigung des Geschosses beiträgt und nicht ein Teil des Gases an dem Geschoß vorbei entweichen kann.Another problem is seen in the fact that the ammunition for gas pressure weapons, viewed in a direction perpendicular to the axial direction of the barrel, usually has a maximum outer diameter which is slightly oversized compared to the inner diameter of the barrel. This excess must be reduced when a bullet is inserted into the barrel - the bullet is calibrated. This is to ensure that the projectile seals the barrel towards the muzzle in its shot preparation position, so that when the shot is fired, the full gas pressure contributes to the acceleration of the projectile and a part of the gas cannot escape past the projectile.

Es hat sich in der Praxis herausgestellt, daß die Trefferlage des Geschosses entscheidend davon abhängt, wie das Geschoß in den Lauf eingeführt worden ist. So erzielen bspw. verschiedene Schützen auch dann verschiedene Schußbilder, wenn die Waffe fest auf das Ziel einjustiert eingespannt ist, der Abzug automatisch betätigt wird und lediglich das Einführen der Munition von Hand vorgenommen wird. Auch ein einzelner Schütze erzielt unterschiedliche Schußbilder je nachdem, ob er die Munition sorgfältig oder nachlässig in den Lauf einführt. Dies wird von den Schützen als äußerst unangenehm empfunden.It has been found in practice that the hit position of the projectile depends crucially on how the projectile was introduced into the barrel. For example, different shooters also achieve different shots when the weapon is firmly adjusted to the target, the trigger is actuated automatically and only the ammunition is inserted by hand. Even a single shooter will get different shots depending on whether he carefully or carelessly inserts the ammunition into the barrel. The shooters find this extremely uncomfortable.

Die EP-A-0 538 733 ist ein Stand der Technik gemäß Art. 54(3) EPÜ und betrifft eine zum Einsatz bei Gasdruckwaffen geeignete Druckgas-Kartusche, wobei im Innern der Kartusche eine Expansionskammer ausgebildet ist. Mittels dieser Kartusche und ein Diabologeschoß abgeschoßen. Diese Druckschrift befaßt sich insbesondere mit dem Innenaufbau der Kartusche sowie mit der Zusammensetzung des Treibmittelsatzes.EP-A-0 538 733 is prior art in accordance with Art. 54 (3) EPC and relates to a compressed gas cartridge suitable for use with gas pressure weapons, an expansion chamber being formed in the interior of the cartridge. Shot down using this cartridge and a diabolo round. This document deals in particular with the internal structure of the cartridge and with the composition of the propellant set.

Die US-A-3 474 560 und die US-A-1 817 273 betreffen Feuerwaffen. Die bei Feuerwaffen im Vergleich zu Gasdruckwaffen wesentlich höhere, bei einem Schuß freigesetzte Energie und der hieraus resultierende höhere Druck machen zur Vermeidung eines Gasaustritts zum mündungsfernen Ende der Waffe hin stets eine gesonderte Dichtung erforderlich.US-A-3 474 560 and US-A-1 817 273 relate to firearms. The much higher energy released in a shot than firearms compared to gas pressure weapons and the resulting higher pressure always make a separate seal necessary to avoid gas leakage towards the muzzle end of the weapon.

Aus der US-A-1 817 273 ist eine Übungsmunition für eine Feuerwaffe bekannt, mit welcher Soldaten u.a. an den Rückstoß der Waffe gewöhnt werden sollen. Die Übungsmunition umfaßt ein Projektil, wie es für Gasdruckwaffen üblich ist und das auf eine Sicherheitskartusche aufgeklebt ist. In der Schußvorbereitungsstellung ragt das Projektil nur mit seinem Kopfteil geringfügig in den Laufkanals hinein. Die Kartusche weist einen Kopfteil aus Papier auf, dessen Außenumfang in deutlichem Abstand von der Innenumfangsfläche der Kartuschenaufnahmekammer angeordnet ist.From US-A-1 817 273 a practice ammunition for a firearm is known, with which soldiers and others. get used to the recoil of the weapon. The practice ammunition includes a projectile, as is customary for gas pressure weapons, and which is glued to a security cartridge. In the shot preparation position, the projectile only protrudes slightly with its head part into the barrel channel. The cartridge has a head part made of paper, the outer circumference of which is arranged at a clear distance from the inner circumferential surface of the cartridge receiving chamber.

Aus der US-A-3 474 560 ist eine Feuerwaffe bekannt, bei welcher sowohl in der Hülse als auch im Ladeschieber gesonderte Dichtungsmittel zur Abdichtung des Laufs zum mündungsfernen Ende hin vorgesehen sind, nämlich Labyrinth-Dichtungen in Form von Nuten.From US-A-3 474 560 a firearm is known in which separate sealing means for sealing the barrel towards the muzzle end are provided in both the sleeve and in the loading slide, namely labyrinth seals in the form of grooves.

Bei dem aus der US-A- 3 302 319 bekannten Waffensystem wird zur Vorbereitung eines Schusses ein Projektil in die Zuführung eingesetzt. Dieses Projektil ist derart ausgebildet, daß es hierbei den Laufkanal zum Projektilaustrittsende hin abdichtet. Ferner wird eine Druckkolbenvorrichtung gespannt, wie dies von einer herkömmlichen Gasdruckwaffe bekannt ist. Beim Schuß wird die Druckkolbenvorrichtung ausgelöst. Durch den sich aufbauenden Druck zündet ein Treibmittelsatz, der in einem einstückig mit dem Projektil ausgebildeten und an seinem dem Projektilaustrittsende abgekehrten Ende offenen Hohlzylinder angeordnet ist, nach dem "Diesel-Effekt". Durch die Dichtwirkung des Projektils ist gewährleistet, daß der Treibmittelsatz sicher zündet. Jedoch wird das Projektil erst durch das vom Treibmittelsatz abgegebene Druckgas zum Projektilaustrittsende hin beschleunigt. Gemäß vorstehendem muß bei dem bekannten Waffensystem ein besonders ausgebildetes Projektil verwendet werden. Dies ist aber bei Gasdruckwaffen oftmals unerwünscht bzw. nicht möglich. So dürfen bspw. im Sportschützenbereich nur bestimmte Projektile eingesetzt werden.In the weapon system known from US-A-3 302 319, a projectile is inserted into the feeder in preparation for a shot. This projectile is designed in such a way that it seals the barrel channel towards the projectile exit end. Furthermore, a pressure piston device is tensioned, as is known from a conventional gas pressure weapon. The pressure piston device is triggered when the shot is fired. Due to the pressure that builds up, a propellant charge, which is arranged in a hollow cylinder formed in one piece with the projectile and open at its end facing away from the projectile outlet end, ignites according to the "diesel effect". The sealing effect of the projectile ensures that the propellant charge ignites safely. However, the projectile is only accelerated towards the end of the projectile by the compressed gas released by the propellant charge. According to the above, a specially designed projectile must be used in the known weapon system. However, this is often undesirable or not possible with gas pressure weapons. For example, only certain projectiles may be used in the area of sports shooters.

Demgegenüber ist es Aufgabe der Erfindung, ein Gasdruck-Waffensystem anzugeben, welches bei einfacher Fertigung der Abschußvorrichtung, insbesondere bei Verzicht auf gesonderte Vorrichtungen zum Abdichten des mündungsfernen Laufendes, reproduzierbare Bedingungen für die Abgabe von Schüssen zu schaffen ermöglicht.In contrast, it is an object of the invention to provide a gas pressure weapon system which allows reproducible conditions for the firing of shots with simple manufacture of the launcher, in particular without the need for separate devices for sealing the muzzle away from the muzzle.

Diese Aufgabe wird erfindungsgemäß durch ein Gasdruck-Waffensystem mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention by a gas pressure weapon system with the features of claim 1.

Erfindungsgemäß ist somit im Bereich der Zuführung des Laufkanals in Axialflucht mit dem Laufkanal eine Kartuschenaufnahmekammer vorgesehen, welche eine gesondert von dem Projektil einzuführende, für jeweils einen Schuß verwendbare Druckgaserzeugungskartusche in einer Position hinter dem in Schußvorbereitungsstellung befindlichen Projektil aufnimmt, wobei diese Druckgaserzeugungskartusche den Treibmittelsatz enthält. Da das Projektil und die Kartusche erfindungsgemäß als separate Teile vorgesehen sind, werden beim Laden des Waffensystems nacheinander zunächst das Projektil und hierauf die Kartusche in die Kartuschenaufnahmekammer eingeführt.According to the invention, a cartridge receiving chamber is thus provided in the region of the feed of the barrel channel in axial alignment with the barrel channel, which holds a pressurized gas generating cartridge that can be inserted separately from the projectile and can be used for one shot each, in a position behind the projectile that is in the preparation position for the shot, this pressurized gas generating cartridge containing the propellant set. Since the projectile and the cartridge are provided according to the invention as separate parts, the projectile and then the cartridge are first introduced into the cartridge receiving chamber when the weapon system is loaded.

Beim Einschieben des Projektils in den Laufkanal tritt eine Durchmessereinengung des rückwärtigen Endbereichs des Projektils ein, so daß der Außendurchmesser des Projektils in der Schußvorbereitungsstellung an den Innendurchmesser des Laufkanals angepaßt ist, d.h. daß das Projektil beim Einschieben in den Laufkanal kalibriert wird.When the projectile is inserted into the barrel channel, the rear end region of the projectile is narrowed in diameter, so that the outside diameter of the projectile in the preparation position is adapted to the inside diameter of the barrel channel, ie the projectile is calibrated when it is inserted into the barrel channel.

Um sicherzustellen, daß sich bei Abgabe des Druckgases durch den Treibmittelsatz druckverlustfrei ein effektiver, das Projektil beschleunigender Gasdruck aufgebaut werden kann, weist dabei die Kartusche ein Kartuschengehäuse auf Ferner sind einander zugekehrte Endteile des Projektils und des Kartuschengehäuses zur gegenseitigen Anlage längs eines die Achse umgebenden Rings ausgebildet, wobei zwischen den einander zugekehrten Endteilen innerhalb dieses Rings ein Gasaufnahmeraum gebildet ist und wobei das Endteil des Kartuschengehäuses eine in diesen Gasaufnahmeraum mündende Gasaustrittöffnung besitzt.In order to ensure that an effective gas pressure which accelerates the projectile can be built up when the compressed gas is released by the propellant charge, the cartridge has a cartridge housing.Furthermore, mutually facing end parts of the projectile and the cartridge housing are for mutual contact along a ring surrounding the axis formed, a gas receiving space is formed between the mutually facing end parts within this ring and wherein the end part of the cartridge housing has a gas outlet opening opening into this gas receiving space.

Der vorstehend genannte Gasaufnahmeraum ist von einer Aushöhlung des Projektils an dessen rückwärtigem Ende und einem verjüngten Vorsprung des Kartuschengehäuses an dessen vorderem Ende gebildet, wobei die Aushöhlung und der verjüngte Vorsprung zwischen sich den Gasaufnahmeraum begrenzen.The aforementioned gas receiving space is formed by a hollow of the projectile at its rear end and a tapered projection of the cartridge housing at its front end, the hollow and the limit the tapered projection between them the gas receiving space.

Eine gute Dichtwirkung wird dabei dadurch erzielt, sowohl die Aushöhlung als auch der Vorsprung jeweils von einer Konusfläche begrenzt sind.A good sealing effect is achieved by both the cavity and the protrusion being bounded by a conical surface.

Um sowohl eine problemlose Einsetzbarkeit der Kartusche in die Kartuschenaufnahmekammer sicherzustellen als auch nach Aufheben der Dichtwirkung durch die Anlage von Projektil und Kartusche eine zuverlässige Abdichtung der Kartuschenaufnahmekammer zu gewährleisten ist der Außendurchmesser der Kartusche auf den Innendurchmesser der Kartuschenaufnahmekammer derart abgestimmt, daß die Kartusche leichtgängig in die Kartuschenaufnahmekammer eingeführt werden kann, und ist ferner die Kartusche wenigstens teilweise aus Kunststoff derart expansionsfähig ausgebildet, daß sie sich unter der Wirkung eines sich in ihrem Inneren aufbauenden Gasdrucks gasdicht an die Innenumfangsfläche der Kartuschenaufnahmekammer anlegt.In order to ensure that the cartridge can be inserted into the cartridge receiving chamber without any problems and also to ensure that the cartridge receiving chamber is reliably sealed after the projectile and cartridge have been removed, the outside diameter of the cartridge is matched to the inside diameter of the cartridge receiving chamber in such a way that the cartridge moves easily into the Cartridge receiving chamber can be inserted, and the cartridge is at least partially made of plastic so expandable that it is gas-tight against the inner peripheral surface of the cartridge receiving chamber under the action of a gas pressure building up inside.

Infolge der Dichtwirkung, die davon berrührt, daß der Mantel der Kartusche aus einem nachgiebigen Material, bspw. Kunststoff, gefertigt ist, kann somit auf ein gesondertes Dichtungselement verzichtet werden. Dies ermöglicht darüber hinaus die Herstellung einer besonders preisgünstigen und leichten Waffe. Es muß nämlich nur noch der Lauf der Waffe mit hoher Präzision hergestellt werden. Alle anderen Bauteile der Waffe können aus leichten Werkstoffen, bspw. Kunststoff oder Aluminium, gebildet sein und müssen nicht mit hoher Präzision bearbeitet sein.As a result of the sealing effect, which is affected by the fact that the jacket of the cartridge is made of a resilient material, for example plastic, a separate sealing element can thus be dispensed with. This also enables the production of a particularly inexpensive and light weapon. It only has to be the barrel of the weapon be manufactured with high precision. All other components of the weapon can be made of light materials, for example plastic or aluminum, and do not have to be machined with high precision.

Im Hinblick auf eine besonders gute Dichtwirkung ist es besonders bevorzugt, wenn die Konusflächen der Aushöhlung und des Vorsprungs wenigstens auf einem Teil ihrer axialen Längen übereinstimmenden Konuswinkel besitzen.In view of a particularly good sealing effect, it is particularly preferred if the conical surfaces of the cavity and of the projection have conical angles that match at least over part of their axial lengths.

Durch Positionieren der Kartusche in Achsrichtung des Laufkanals mittels eines Anschlags kann eine reproduzierbare Positionierung der Kartuschen sichergestellt werden.By positioning the cartridge in the axial direction of the running channel by means of a stop, a reproducible positioning of the cartridges can be ensured.

Um verhindern zu können, daß das Projektil beim Einlegen in die Kartuschenaufnahmekammer in unerwünschter Weise von Hand verformt, und ferner sicherstellen zu können, daß sich das Projektil in seiner Schußvorbereitungsstellung im Laufkanal befindet, wird vorgeschlagen, daß der Innendurchmesser der Kartuschenaufnahmekammer den Maximaldurchmesser des Projektils geringfügig überschreitet, so daß das Projektil leichtgängig in die Kartuschenaufnahmekammer einführbar ist, und daß der Innendurchmesser des Laufkanals einen gegenüber dem Innendurchmesser der Kartuschenaufnahmekammer kleineren Wert aufweist, wobei das Projektil bei Einführung der Kartusche in die Kartuschenaufnahmekammer durch die Kartusche in den Laufkanal einschiebbar ist.In order to be able to prevent the projectile from being undesirably deformed by hand when it is inserted into the cartridge receiving chamber, and also to be able to ensure that the projectile is in its barrel preparation position in the barrel channel, it is proposed that the inside diameter of the cartridge receiving chamber slightly exceed the maximum diameter of the projectile, so that the projectile can be inserted easily into the cartridge receiving chamber, and that the inside diameter of the barrel channel has a smaller value than the inside diameter of the cartridge receiving chamber , the projectile being insertable through the cartridge into the barrel channel when the cartridge is inserted into the cartridge receiving chamber.

Durch Ausbildung des Übergangs zwischen der Kartuschenaufnahmekammer und dem Laufkanal als konischen Übergang kann die reproduzierbare Kalibrierung der Projektile unterstützt werden.The reproducible calibration of the projectiles can be supported by designing the transition between the cartridge receiving chamber and the barrel channel as a conical transition.

Dadurch, daß der Laufkanal angrenzend an die Kartuschenaufnahmekammer einen glattzylindrischen Abschnitt und an diesen glattzylindrischen Abschnitt zum Projektilaustrittsende des Laufkanals hin anschließend einen mit Zügen versehenen Abschnitt besitzt, wobei in einer Schußvorbereitungsstellung ein vorderer Endbereich des Projektils von dem mit Zügen versehenen Abschnitt und ein rückwärtiger Endbereich des Projektils von dem glattzylindrischen Abschnitt aufgenommen sind, können die Kalibrierung des Projektils und das Einführen des Projektils in den mit Zügen versehenen Abschnitt des Laufkanals nacheinander vorgenommen werden, so daß die hierbei auf das Projektil ausgeübten Kräfte klein gehalten werden können, was die Reproduzierbarkeit der Kalibrierung weiter verbessert.Characterized in that the barrel channel adjacent to the cartridge receiving chamber has a smooth cylindrical section and this smooth cylindrical section to the projectile exit end of the barrel channel has a section provided with trains, with a front end region of the projectile from the train section and a rear end region in a shot preparation position of the projectile are taken up by the smooth cylindrical section, the calibration of the projectile and the insertion of the projectile into the section of the running channel provided with trains can be carried out in succession, so that the forces exerted on the projectile can be kept small, which reduces the reproducibility of the calibration further improved.

Um sicherstellen zu können, daß beim Einführen in den mit Zügen versehenen Abschnitt des Laufkanals die Kalibrierung des Projektils erhalten bleibt und ferner die hierbei auf das Projektil ausgeübten Kräfte möglichst klein sind, wird vorgeschlagen, daß die Bodenfläche der Züge mit der Innenumfangsfläche des glattzylindrischen Abschnitts fluchtet und daß zwischen den Zügen liegende Felder des mit Zügen versehenen Abschnitts des Laufkanals gegenüber dem glattzylindrischen Abschnitt radial einwärts geringfügig vorstehen und über konische Übergangsflächen in den glattzylindrischen Abschnitt übergehen.In order to be able to ensure that the calibration of the projectile is retained when it is inserted into the section of the running channel provided with trains and that the forces exerted on the projectile are as small as possible, it is proposed that the bottom surface of the trains align with the inner peripheral surface of the smooth cylindrical section and that lying between the trains fields of the section of the running channel provided with trains project slightly radially inwards relative to the smooth cylindrical section and merge into the smooth cylindrical section via conical transition surfaces.

Wenn der Außendurchmesser des vorderen Projektilabschnitts kleiner ist als der durch die Felder definierte Durchmesser des mit Zügen versehenen Abschnitts des Laufkanals, so kann gewährleistet werden, daß sämtliche zum Kalibrieren und Einführen des Projektils in den mit Zügen versehenen Abschnitt erforderlichen Verformungen des Projektil an dessen hinterem Abschnitt vorgenommen werden und sich das Projektil somit beim Schuß gleichmäßiger bewegt.If the outer diameter of the front projectile section is smaller than the diameter defined by the fields of the section of the running channel provided with trains, it can be ensured that all deformations of the projectile required for calibrating and inserting the projectile into the section provided with trains at the rear section be made and the projectile thus moves more evenly when fired.

Die vorstehenden Vorteile können in einfacher Weise dadurch erzielt werden, daß ein Projektil vom Diabolo-Typ eingesetzt wird.The above advantages can be easily achieved by using a projectile of the diabolo type.

In Fig. 1 ist ein im folgenden mit 10 bezeichnetes Gasdruckgewehr im abgeschossenen Zustand dargestellt. Das Gewehr 10 umfaßt einen Lauf 12 mit einem Laufkanal 12d und einer Mündung 12g, ein Gehäuse 14 und einen Schaft 16. In einem mündungsfernen Bereich 18 des Laufs 12 ist eine Kartusche 20 angeordnet, welche das Treibgas zum Schießen bereitstellt. Die Ausbildung der Kartusche 20 ist Gegenstand einer gesonderten Anmeldung. Daher wird im folgenden nur soweit erforderlich auf die Kartusche 20 eingegangen.1 shows a gas pressure rifle, designated 10 below, in the fired state. The rifle 10 comprises a barrel 12 with a barrel channel 12d and a muzzle 12g, a housing 14 and a barrel 16. In a region 18 of the barrel 12 remote from the muzzle there is a cartridge 20 which provides the propellant gas for shooting. The formation of the cartridge 20 is the subject of a separate application. Therefore, the cartridge 20 is only discussed as far as necessary below.

Die Kartusche 20 ist an ihrem im schußbereiten Zustand geschoßfernen Ende 20a (s. Fig. 6 und 7) mit einem Zündhütchen (nicht dargestellt) versehen, welches mittels eines Schlagbolzens 22 (s. Fig. 1) gezündet werden kann. Das sich als Folge der Zündung entwickelnde Gas strömt in eine Expansionskammer 20b der Kartusche, welche zum Aufbau und zur Homogenisierung des Drucks dient. Das Druckgas tritt an einem vorzugsweise konisch zulaufenden Kopfteil 20c der Kartusche 20 aus einer Düse 20f aus und beschleunigt ein im Lauf 12 angeordnetes Geschoß bzw. Projektil 24 zur Mündung des Laufs 12 hin. Die Düse 20f kann bspw. einen Durchmesser von etwa 2 mm aufweisen.The cartridge 20 is provided with a primer (not shown) at its end 20a (see FIGS. 6 and 7) which is remote from the shot and which can be ignited by means of a firing pin 22 (see FIG. 1). The gas which develops as a result of the ignition flows into an expansion chamber 20b of the cartridge, which serves to build up and homogenize the pressure. The compressed gas occurs at a preferably tapered head part 20c Cartridge 20 out of a nozzle 20f and accelerates a projectile or projectile 24 arranged in the barrel 12 towards the mouth of the barrel 12. The nozzle 20f can have a diameter of approximately 2 mm, for example.

Zum Nachladen der Waffe 10 wird zunächst eine am Gehäuse 14 bei 26 schwenkbar angebrachte Ladeklappe 28 in Richtung des Pfeils A verschwenkt (s. Fig. 1 und 2). Ein Verschlußschieber 30 ist in einer zur Achsrichtung des Laufs 12 im wesentlichen parallel verlaufenden Aufnahme 14a in Richtung der Pfeile B und B' hin- und herverschiebbar gelagert. Der Verschlußschieber 30 ist über einen Gelenkhebel 32 und zwei Bolzen 32a und 32b betriebsmäßig mit der Ladeklappe 28 verbunden, so daß der Verschlußschieber 30 beim Öffnen der Ladeklappe 28, d.h. beim Verschwenken der Ladeklappe in Richtung des Pfeils A, in der Aufnahme 14a in Richtung des Pfeils B, d.h. vom Lauf 12 weg, verschoben wird.To reload the weapon 10, a loading flap 28 pivotably mounted on the housing 14 at 26 is first pivoted in the direction of the arrow A (see FIGS. 1 and 2). A locking slide 30 is mounted in a receptacle 14a which is essentially parallel to the axial direction of the barrel 12 and can be pushed back and forth in the direction of the arrows B and B '. The locking slide 30 is operatively connected to the loading hatch 28 via an articulated lever 32 and two bolts 32a and 32b so that the locking slide 30 when the loading hatch 28 is opened, i. when pivoting the loading flap in the direction of arrow A, in the receptacle 14a in the direction of arrow B, i.e. away from barrel 12.

Am laufnahen Ende des Verschlußschiebers 30 ist ein Ausreißhaken 34 angebracht, welcher in der Stellung gemäß Fig. 1 einen Kragen 20d der Kartusche 20 umgreift (s. auch Fig. 7) und die Kartusche 20 beim Öffnen der Ladeklappe automatisch aus dem mündungsfernen Bereich 18 des Laufs 12 entfernt.At the end of the slide slide 30 near the barrel, a pull-out hook 34 is attached, which in the position shown in FIG. 1 engages around a collar 20d of the cartridge 20 (see also FIG. 7) and automatically opens the cartridge 20 from the area 18 of the mouth when the loading flap is opened Run 12 removed.

Weiterhin wird beim Öffnen der Ladeklappe automatisch ein Abzugssystem 36 der Waffe 10 gespannt. Das Abzugssystem 36 umfaßt ein am Gehäuse 14 bei 38a schwenkbar gelagertes Schlagstück 38, eine Schlagstange 40 sowie einen bei 42a schwenkbar am Gehäuse gelagerten Abzug 42. Ein Kopfteil 40a der Schlagstange 40 steht mit einem Bolzen 38b des Schlagstücks 38 in Eingriff. Eine Schraubendruckfeder 40b, die sich einenends am Gehäuse 14 und anderenends am Kopf 40a der Schlagstange abstützt, spannt das Schlagstück 38 in die in Fig. 1 dargestellte Stellung vor. Eine Schraubendruckfeder 42b, die sich einenends am Gehäuse 14 und anderenends an einem in Fig. 1 unteren Hebelarm 42c abstützt, spannt den Abzug 42 derart vor, daß ein in Fig. 1 oberer Hebelarm 42d des Abzugs 42 zur Anlage am Schlagstück 38 kommt.Furthermore, a trigger system 36 of the weapon 10 is automatically cocked when the loading flap is opened. The trigger system 36 comprises a striker 38 pivotably mounted on the housing 14 at 38a, a striker 40 and a trigger 42 pivotably mounted on the housing at 42a. A head part 40a of the striker 40 engages with a bolt 38b of the striker 38. A helical compression spring 40b, which is supported at one end on the housing 14 and at the other end on the head 40a of the impact bar, biases the impact piece 38 into the position shown in FIG. 1. A helical compression spring 42b, which is supported at one end on the housing 14 and at the other end on a lower lever arm 42c in FIG. 1, tensions the trigger 42 in such a way that an upper lever arm 42d of the trigger 42 in FIG. 1 comes to rest on the striker 38.

Bei einer Verschiebung des Verschlußschiebers 30 in Richtung des Pfeils B beim öffnen der Ladeklappe 28 wird das Schlagstück 38 im Uhrzeigersinn gegen die Vorspannkraft der Feder 40b verschwenkt. Hierdurch laufen Rastzähne 38c des Schlagstücks 38 am oberen Hebelarm 42d des Abzugs 42 vorbei, woraufhin der Abzug 42 durch die Vorspannkraft der Druckfeder 42b im Uhrzeigersinn verschwenkt wird und mit einer Stirnfläche 42e des oberen Hebelarms 42d gegen Stützflanken der Rastzähne 38c anliegt. Infolge dieser Verrastung wird das Schlagstück 38 auch nach Schließen der Ladeklappe 28 in der in Fig. 4 dargestellten Auslösebereitschaftsstellung gehalten. Nunmehr befindet sich die Waffe in der in Fig. 2 dargestellten Stellung und kann erneut geladen werden.When the slide slide 30 is displaced in the direction of arrow B when the loading flap 28 is opened, the striking piece 38 is pivoted clockwise against the biasing force of the spring 40b. As a result, locking teeth 38c of the striking piece 38 pass the upper lever arm 42d of the trigger 42, whereupon the trigger 42 is pivoted clockwise by the biasing force of the compression spring 42b and rests with an end face 42e of the upper lever arm 42d against supporting flanks of the locking teeth 38c. As a result of this latching, the striking piece 38 is held in the ready-to-release position shown in FIG. 4 even after the loading flap 28 has been closed. The weapon is now in the position shown in FIG. 2 and can be reloaded.

Das Laden der Waffe wird im folgenden anhand der Fig. 2 und 3 näher erläutert werden. Im mündungsfernen Bereich 18 des Laufs 12 ist eine Aufnahmekammer 44 ausgebildet, in welche zum Laden der Waffe ein Geschoß 24 eingelegt wird (s. Fig. 3). Die Aufnahmekammer 44 ist derart ausgebildet, daß das Geschoß 24 im wesentlichen ohne Verformung eingelegt werden kann. Anschließend muß noch eine Kartusche 20 hinter dem Geschoß 24 angeordnet werden. Auf die genaue Ausbildung der Aufnahmekammer 44 (auch als Kartuschenaufnahmekammer bzw. Geschoßaufnahmekammer bezeichnet) wird weiter unten anhand der Beschreibung der Fig. 6 und 7 noch ausführlich eingegangen werden.The loading of the weapon will be explained in more detail below with reference to FIGS. 2 and 3. In the region 18 of the barrel 12 remote from the muzzle, a receiving chamber 44 is formed, into which a projectile 24 is inserted for loading the weapon (see FIG. 3). The receiving chamber 44 is designed such that the projectile 24 can be inserted substantially without deformation. Then a cartridge 20 must be arranged behind the floor 24. The precise design of the receiving chamber 44 (also referred to as the cartridge receiving chamber or the floor receiving chamber) will be discussed in greater detail below with reference to the description of FIGS. 6 and 7.

In dem in den Figuren dargestellten Ausführungsbeispiel der Waffe 10 ist eine Mehrzahl von Kartuschen 20 in einem Magazin 46 angeordnet, welches einen in Schußstellung der Waffe 10 unter dem Lauf 12 angeordneten Aufnahmebehälter 48 und eine Transporteinrichtung 50 aufweist. Die Mehrzahl von Kartuschen 20 ist in dem Aufnahmebehälter 48 in Achsrichtung des Laufs 12 gesehen hintereinander angeordnet. Die Kartuschen 20 sind in dem Aufnahmebehälter 48 mittels einer in den Figuren nicht dargestellten Druckfeder in Richtung zur Transporteinrichtung 50 hin vorgespannt. Die Transporteinrichtung 50 umfaßt einen Ladeschieber 52 und eine Schraubendruckfeder 54. Die Schraubendruckfeder 54 stützt sich einenends am Gehäuse 14 und anderenends am Ladeschieber 52 ab und spannt diesen in die in Fig. 3 dargestellte angehobene Stellung vor.In the exemplary embodiment of the weapon 10 shown in the figures, a plurality of cartridges 20 are arranged in a magazine 46 which has a receiving container 48 arranged under the barrel 12 in the firing position of the weapon 10 and a transport device 50. The plurality of cartridges 20 are arranged one behind the other in the receiving container 48, as seen in the axial direction of the barrel 12. The Cartridges 20 are prestressed in the receiving container 48 by means of a compression spring, not shown in the figures, in the direction of the transport device 50. The transport device 50 comprises a loading slide 52 and a helical compression spring 54. The helical compression spring 54 is supported at one end on the housing 14 and at the other end on the loading slide 52 and biases the latter into the raised position shown in FIG. 3.

Zum Nachladen einer Kartusche wird der Ladeschieber 52 von Hand entgegen der Vorspannkraft der Feder 54 in seine in Fig. 2 dargestellte untere Stellung übergeführt. Hierzu betätigt eine Bedienungsperson einen am Ladeschieber 52 angeordneten, am besten in Fig. 5 zu erkennenden, Ladeschieberknopf 52a. Befindet sich der Ladeschieber 52 in seiner in Fig. 2 dargestellten unteren Stellung, so verschiebt die nicht dargestellte Druckfeder des Aufnahmebehälters 48 die in dem Aufnahmebehälter 48 aufgenommenen Kartuschen 20 um eine Kartuschenlänge in Richtung zur Transporteinrichtung 50 hin. Hierdurch wird eine Kartusche 20 in eine am oberen Ende des Ladeschiebers 52 ausgebildete Ladeschiebermulde 52b eingelegt. Dann wird der Ladeschieber 52 wieder in seine obere Stellung gemäß Fig. 3 übergeführt, in welcher er durch die Vorspannkraft der Schraubendruckfeder 54 gehalten wird. Die in der Ladeschiebermulde 52b angeordnete Kartusche 20 ist nun unmittelbar vor dem Verschlußschieber 30 in ihrer Ladebereitschaftsstellung angeordnet.For reloading a cartridge, the loading slide 52 is moved by hand against the biasing force of the spring 54 into its lower position shown in FIG. 2. For this purpose, an operator actuates a loading slide button 52a arranged on the loading slide 52, which can best be seen in FIG. 5. If the loading slide 52 is in its lower position shown in FIG. 2, the compression spring (not shown) of the receptacle 48 displaces the cartridges 20 received in the receptacle 48 by one cartridge length in the direction of the transport device 50. As a result, a cartridge 20 is inserted into a loading slide recess 52b formed at the upper end of the loading slide 52. Then the loading slide 52 is returned to its upper position according to FIG. 3, in which it is held by the biasing force of the helical compression spring 54. The cartridge 20 arranged in the loading slide trough 52b is now arranged directly in front of the closing slide 30 in its ready-to-load position.

Beim Schließen der Ladeklappe 28, d.h. bei ihrem Verschwenken in Richtung des Pfeils A', wird der Verschlußschieber 30 mittels des Gelenkhebels 32 wieder in Richtung des Pfeils B', d.h. zum Lauf 12 hin, verschoben. Hierbei nimmt der Verschlußschieber 30 die in der Ladeschiebermulde 52b angeordnete Kartusche 20 in Richtung zur Kartuschenaufnahmekammer 44 mit.When closing the loading flap 28, i.e. when it is pivoted in the direction of arrow A ', the locking slide 30 is again moved in the direction of arrow B' by means of the articulated lever 32, i.e. towards barrel 12, shifted. Here, the closing slide 30 takes the cartridge 20 arranged in the loading slide recess 52b in the direction of the cartridge receiving chamber 44.

Die Kartuschenaufnahmekammer 44 ist vorzugsweise zylindersymmetrisch ausgebildet und weist gemäß Fig. 6 an ihrem mündungsfernen Ende einen gegenüber einem Hauptabschnitt 44a radial erweiterten Abschnitt 44b auf. Der Innendurchmesser φ44a des Hauptabschnitts 44a der Kartuschenaufnahmekammer 44 ist relativ zum Außendurchmesser φ20 des Hauptabschnitts 20b der Kartusche 20 leicht überbemessen, so daß die Kartusche 20 leichtgängig in die Kartuschenaufnahmekammer eingeführt werden kann. Der Innendurchmesser des erweiterten Abschnitts 44b entspricht im wesentlichen dem Außendurchmesser des Kragenabschnitts 20d der Kartusche 20a. Die vorzugsweise konisch zulaufenden Flächen des Kopfteils 20c der Kartusche dienen beim Einführen der Kartusche in die Kartuschenaufnahmekammer 44 als Einweisungs und Zentrierflächen. Darüber hinaus greift die Kartusche 20 mit dem konisch zulaufenden Kopfteil 20c in einen Schürzenabschnitt 24a des bei der Gasdruckwaffe 10 bevorzugt verwendeten Diabolo-Geschosses 24 ein, was wiederum zur Zentrierung des Diabolo-Geschosses 24 beiträgt.The cartridge receiving chamber 44 is preferably of cylindrical symmetry and has, according to FIG. 6, on it end remote from the mouth has a section 44b radially widened with respect to a main section 44a. The inner diameter φ 44a of the main section 44a of the cartridge receiving chamber 44 is slightly oversized relative to the outer diameter φ 20 of the main section 20b of the cartridge 20, so that the cartridge 20 can be inserted easily into the cartridge receiving chamber. The inside diameter of the enlarged section 44b corresponds essentially to the outside diameter of the collar section 20d of the cartridge 20a. The preferably tapered surfaces of the head part 20c of the cartridge serve as guiding and centering surfaces when the cartridge is inserted into the cartridge receiving chamber 44. In addition, the cartridge 20 engages with the conically tapering head part 20c in an apron section 24a of the diabolo projectile 24 which is preferably used in the gas pressure weapon 10, which in turn contributes to the centering of the diabolo projectile 24.

Beim weiteren Einführen der Kartusche 20 in die Kartuschenaufnahmekammer 44 wird nun das Geschoß 24 in Fig. 6 zunehmend von der Kartusche 20 nach links verschoben. Hierbei tritt ein Kopf 24b des Geschosses 24 an einer konischen Ringkante 44c vorbei in einen glattzylindrischen Abschnitt 12c des Laufkanals 12d ein und gelangt schließlich in einen mit Feldern 12a und Zügen 12b versehenen Abschnitt 12e des Laufkanals 12d.When the cartridge 20 is further inserted into the cartridge receiving chamber 44, the projectile 24 in FIG. 6 is increasingly shifted from the cartridge 20 to the left. A head 24b of the projectile 24 enters a smooth cylindrical section 12c of the running channel 12d past a conical ring edge 44c and finally reaches a section 12e of the running channel 12d provided with fields 12a and cables 12b.

Der von den Zügen 12b definierte Innendurchmesser φ12b des Abschnitts 12e des Laufkanals 12d und der Innendurchmesser φ12c des glattzylindrischen Abschnitts 12c weisen den gleichen Wert auf, wohingegen der von den Feldern 12a definierte Innendurchmesser φ12a des Abschnitts 12e des Laufkanals 12d einen kleineren Wert aufweist als der Innendurchmesser φ12c.The inner diameter φ 12b of the section 12e of the running channel 12d defined by the cables 12b and the inner diameter φ 12c of the smooth cylindrical section 12c have the same value, whereas the inside diameter φ 12a of the section 12e of the running channel 12d defined by the fields 12a has a smaller value than the inner diameter φ 12c .

Der Außendurchmesser φ24b des Kopfteils 24b ist vorzugsweise geringfügig kleiner bemessen als der durch die Felder definierte Innendurchmesser φ12a des Laufkanals 12d, so daß der Kopf 24b des Geschosses 24 beim Eintritt in den mit Feldern und Zügen versehenen Abschnitt 12e des Laufkanals 12d nicht verformt wird. Am Übergang zwischen dem glattzylindrischen Abschnitt 12c und den Feldern 12a sind konische Übergangsflächen 12f vorgesehen, die eine Zentrierfunktion für den Kopf 24b des Geschosses 24 haben.The outer diameter φ 24b of the head part 24b is preferably dimensioned slightly smaller than the inner diameter φ 12a of the running channel 12d defined by the fields, so that the head 24b of the projectile 24 is not deformed when it enters the section 12e of the running channel 12d provided with fields and trains. At the transition between the smooth cylindrical section 12c and the fields 12a, conical transition surfaces 12f are provided, which have a centering function for the head 24b of the projectile 24.

Der Innendurchmesser φ12c des glattzylindrischen Abschnitts 12c des Laufkanals 12d weist einen kleineren Wert auf als der Innendurchmesser φ44a des Hauptabschnitt 44a der Kartuschenaufnahmekammer 44. Den Übergang zwischen diesen beiden Durchmessern φ12c und φ44a bildet die konische Rinkante 44c. Der maximale Außendurchmesser φ24a des Schürzenabschnitts 24a des Geschosses 24 weist einen kleineren Wert auf als der Innendurchmesser φ44a des Hauptabschnitts 44a der Kartuschenaufnahmekammer 44, jedoch einen größeren Wert als der Innendurchmesser φ12c des glattzylindrischen Abschnitts 12c des Laufkanals 12d.The inner diameter φ 12c of the smooth cylindrical section 12c of the running channel 12d has a smaller value than the inner diameter φ 44a of the main section 44a of the cartridge receiving chamber 44. The transition between these two diameters φ 12c and φ 44a forms the conical groove 44c. The maximum outside diameter φ 24a of the apron section 24a of the projectile 24 has a smaller value than the inside diameter φ 44a of the main section 44a of the cartridge receiving chamber 44, but a larger value than the inside diameter φ 12c of the smooth cylindrical section 12c of the running channel 12d.

Somit wird der Schürzenabschnitt 24a des Geschosses 24, wenn er mittels der Kartusche 20 in den Lauf 12 eingeführt wird, von der Ringkante 44c kalibriert, d.h. leicht verformt derart, daß er im wesentlichen spaltfrei an der Aussenumfangsfläche des Abschnitts 12c des Laufs 12 anliegt, wie dies bspw. in Fig. 7 dargestellt ist. Die Kartusche 20 ist in dieser Stellung vollständig in die Kartuschenaufnahmekammer 44 eingeführt, wobei ein weiteres Einführen der Kartusche 20 in den Laufkanal 12d dadurch verhindert wird, daß der Kragenabschnitt 20d der Kartusche 20 an der zwischen Hauptabschnitt 44a und erweitertem Abschnitt 44b der Kartuschenaufnahmekammer 44 ausgebildeten Kante anliegt.Thus, the apron portion 24a of the projectile 24, when inserted into the barrel 12 by means of the cartridge 20, is calibrated by the ring edge 44c, i.e. slightly deformed in such a way that it lies essentially without a gap on the outer peripheral surface of the section 12c of the barrel 12, as is shown, for example, in FIG. 7. In this position, the cartridge 20 is completely inserted into the cartridge receiving chamber 44, further insertion of the cartridge 20 into the running channel 12d being prevented by the collar portion 20d of the cartridge 20 at the edge formed between the main portion 44a and the expanded portion 44b of the cartridge receiving chamber 44 is present.

In der somit erreichten Schußvorbereitungsstellung (Fig. 7) ist der Schürzenabschnitt 24a des Geschosses 24 zwischen dem konischen Kopfteil 20c der Kartusche 20 und den konischen Übergangsflächen 12f der Felder 12a aufgenommen, wobei die Felder 12a bereits leicht in den Schürzenabschnitt 24a des Geschosses 24 eingreifen. Hierbei liegen der Schürzenabschnitt 24a des Geschosses 24 und der konische Kopfteil 20c der Kartusche 20 mit konischen Begrenzungsflächen 24al bzw. 20cl, die den gleichen Konuswinkel a aufweisen, dichtend aneinander an. Somit ist die Düse 20f der Kartusche in einen gasdicht abgeschlossenen Gasaufnahmeraum 24c im Schürzenabschnitt 24a des Geschosses 24 gerichtet.In the shot preparation position thus achieved (FIG. 7), the apron section 24a of the projectile 24 is accommodated between the conical head part 20c of the cartridge 20 and the conical transition surfaces 12f of the fields 12a, the fields 12a already slightly engaging in the apron section 24a of the projectile 24. Here are the apron section 24a of the projectile 24 and the conical head part 20c of the cartridge 20 with conical boundary surfaces 24al or 20cl, which have the same cone angle a, sealingly against one another. The nozzle 20f of the cartridge is thus directed into a gas-tightly closed gas-receiving space 24c in the skirt portion 24a of the projectile 24.

Die in Fig. 7 dargestellte Schußvorbereitungsstellung von Geschoß 24 und Kartusche 20 entspricht der in Fig. 4 dargestellten Stellung der Waffe 10 im schußbereiten Zustand. Wird nun ausgehend von Fig. 4 der Abzug 42 der Waffe 10 betätigt, d.h. der Abzug 42 entgegen der Vorspannkraft der Feder 42b entgegen dem Uhrzeigersinn gedreht, so wird hierdurch die Verrastung zwischen Abzug 42 und den Rastzähnen 38c des Schlagstücks 38 gelöst. Hieraufhin wird das Schlagstück 38 unter Vermittlung der Schlagstange 40 von der Druckfeder 40b entgegen dem Uhrzeigersinn verschwenkt und schlägt auf ein in Fig. 4 rechtes Ende 22a des Schlagbolzens 22. Der Schlagbolzen 22 schlägt hierauf mit seinem linken Ende 22b auf die Kartusche 20 und zündet somit den Treibsatz. Ein Bolzen 56 dient hierbei als Anschlag für das Schlagstück 38.The shot preparation position of the projectile 24 and the cartridge 20 shown in FIG. 7 corresponds to the position of the weapon 10 shown in FIG. 4 in the ready-to-fire state. 4, the trigger 42 of the weapon 10 is now actuated, i.e. the trigger 42 is rotated counter-clockwise against the biasing force of the spring 42b, the latching between the trigger 42 and the locking teeth 38c of the striker 38 is hereby released. Thereupon, the striking piece 38 is pivoted counterclockwise by the pushing rod 40 by the compression spring 40b and strikes an end 22a of the striking pin 22 on the right in FIG. 4. The striking pin 22 then strikes the cartridge 20 with its left end 22b and thus ignites the propellant. A bolt 56 serves as a stop for the striking piece 38.

Im dargestellten Ausführungsbeispiel ist der Schlagbolzen 22 in einer Zentralbohrung 30a (Fig. 1 und 4) aufgenommen und wird von einer Schlagbolzenfeder 22c in den Figuren nach rechts vorgespannt.In the illustrated embodiment, the firing pin 22 is received in a central bore 30a (FIGS. 1 and 4) and is biased to the right by a firing pin spring 22c in the figures.

Infolge der Zündung des Treibsatzes kommt es in der Kartusche zur Gasentwicklung und zum Druckaufbau. Hierdurch wird der Mantel 20b der Kartusche 20 fest gegen die Innenumfangsfläche des Hauptabschnitts 44a der Kartuschenaufnahmekammer 44 gedrückt, so daß die Kartuschenaufnahmekammer 44 zu ihrem mündungsfernen Ende hin abgedichtet wird. Hierbei ist sichergestellt, daß erst nach Aufbau dieser Dichtwirkung das aus der Düse 20f der Kartusche 20 austretende Gas das Geschoß 24 in Richtung zur Mündung des Laufs 12 hin beschleunigt, wodurch die Dichtung zwischen den Konusflächen 24a1 und 20c1 aufgehoben wird. Bei der Beschleunigung des Geschosses 24 prägen sich die Felder 12a des Laufs 12 in dessen Schürzenabschnitt 24a ein, so daß die in den Zügen 12b des Laufs 12 geführten Teile des Schürzenabschnitts 24a für den Drall des Geschosses 24 sorgen können.As a result of the ignition of the propellant charge, gas develops and pressure builds up in the cartridge. As a result, the jacket 20b of the cartridge 20 is pressed firmly against the inner circumferential surface of the main section 44a of the cartridge receiving chamber 44, so that the cartridge receiving chamber 44 is sealed toward its end remote from the mouth. This ensures that only after this sealing effect has been built up does the gas emerging from the nozzle 20f of the cartridge 20 accelerate the projectile 24 in the direction of the mouth of the barrel 12, as a result of which the seal between the conical surfaces 24a1 and 20c1 is canceled. When the projectile 24 accelerates, the fields 12a of the barrel 12 imprint themselves in its apron section 24a, so that the parts of the apron section 24a guided in the trains 12b of the barrel 12 can provide for the swirl of the projectile 24.

Wie insbesondere aus den Fig. 6 und 7 zu ersehen ist, weist die Kartusche 20 eine Sollbruchstelle 20e in Form eines verjüngten Mantelabschnitts auf, welche in der Stellung gemäß Fig. 7 einer von der Kartuschenaufnahmekammer 44 abzweigenden Durchgang 58 gegenüberliegt. Der Durchgang 58 ist vorzugsweise als Bohrung ausgebildet und verbindet die Kartuschenaufnahmekammer 44 mit der Umgebung. Die Sollbruchstelle 20e soll verhindern, daß mit Hilfe manipulierter Kartuschen 20 bei der Gasdruckwaffe 10 höhere als die gesetzlich zulässigen Höchstschußenergien erzielt werden können. Wird eine Kartusche 20 bspw. in der Art manipuliert, daß ihr Treibmittelsatz verstärkt wird, der zu einer entsprechend verstärkten Gasentwicklung bei der Zündung führt, so birst die Sollbruchstelle dann, wenn der Gasdruck in der Kartusche 20 einen höchstzulässigen Druckwert überschreitet und der Gasdruck kann sich über die Bohrung 58 in die Umgebung abbauen.As can be seen in particular from FIGS. 6 and 7, the cartridge 20 has a predetermined breaking point 20e in the form of a tapered jacket section, which in the position according to FIG. 7 is opposite a passage 58 branching off from the cartridge receiving chamber 44. The passage 58 is preferably designed as a bore and connects the cartridge receiving chamber 44 to the environment. The predetermined breaking point 20e is intended to prevent manipulated cartridges 20 in the gas pressure weapon 10 from being able to achieve higher than the legally permissible maximum shot energies. If a cartridge 20 is manipulated, for example, in such a way that its propellant charge is increased, which leads to a correspondingly increased gas development during ignition, the predetermined breaking point bursts when the gas pressure in the cartridge 20 exceeds a maximum permissible pressure value and the gas pressure can rise Dismantle into the environment via hole 58.

Es soll nochmals festgehalten werden, daß Geschosse 24 mit Hilfe des vorstehend beschriebenen Ladevorgangs reproduzierbar in ein und dieselbe Schußvorbereitungsstellung gebracht werden können. Sämtliche individuellen Einflüsse der die Gasdruckwaffe 10 ladenden Bedienungsperson können wirksam ausgeschlossen werden. Das Geschoß 24 kann, ohne Verformungen unterworfen zu werden, in die Kartuschenaufnahmekammer 44 eingelegt werden. Anschließend wird die als Positioniereinrichtung für das Geschoß wirkende Kartusche 20 mit Hilfe der Schiebereinrichtung 30 in die Kartuschenaufnahmekammer 44 eingeführt, wobei sie erst dann wesentliche Kräfte auf das Geschoß 24 ausübt, wenn ihr Mantel 20b sicher in dem Hauptabschnitt 44a der Kartuschenaufnahmekammer 44 geführt ist. Der konische Kopfteil 20c zentriert den Schürzenabschnitt 24a des Geschosses 24. Die Kartusche 20 drückt den Schürzenabschnitt 24a des Geschosses 24 erst nach erfolgter Zentrierung des Geschosses 24 über die Kalibrierkante 44c. Dies stellt die reproduzierbare Kalibrierung des Geschosses 24 sicher, so daß bei jedem Schuß die gleichen Anfangsbedingungen gegeben sind. Hierdurch läßt sich mit der Gasdruckwaffe 10 ein gleichmäßigeres und besseres Schußbild erzielen.It should be noted once again that projectiles 24 can be reproducibly brought into one and the same shot preparation position with the aid of the loading process described above. All individual influences of the operator loading the gas pressure weapon 10 can be effectively excluded. The projectile 24 can be inserted into the cartridge receiving chamber 44 without being subjected to deformations. The cartridge 20, which acts as a positioning device for the projectile, is then introduced into the cartridge receiving chamber 44 with the aid of the slide device 30, only exerting significant forces on the projectile 24 when its jacket 20b is securely guided in the main section 44a of the cartridge receiving chamber 44. The conical head part 20c centers the Apron section 24a of the projectile 24. The cartridge 20 presses the apron section 24a of the projectile 24 only after the projectile 24 has been centered over the calibration edge 44c. This ensures the reproducible calibration of the projectile 24, so that the same initial conditions are given for each shot. This allows the gas pressure weapon 10 to achieve a more even and better shot pattern.

Weiter ist festzuhalten, daß die Gasdruckwaffe 10 durch die flexible Ausbildung des Mantels 20b der Kartusche 20 ohne gesondertes Dichtungselement zwischen Lauf 12 und dem Rest der Waffe 10 auskommt, da der bei der Zündung der Kartusche 20 entstehende Gasdruck den Kartuschenmantel 20b an die Innenumfangsfläche der Kartuschenaufnahmekammer 44 anpreßt und den mündungsfernen Bereich 18 des Laufs 12 automatisch abdichtet. Die gesamte bei der Zündung der Kartusche 20 freiwerdende Energie wird zur Beschleunigung des Geschosses 24 verwendet. Durch die automatische Abdichtung des Laufs 12 kann die erfindungsgemäße Gasdruckwaffe 10 einfach aufgebaut sein.It should also be noted that the gas pressure weapon 10 does not require a separate sealing element between the barrel 12 and the rest of the weapon 10 due to the flexible design of the jacket 20b of the cartridge 20, since the gas pressure which arises when the cartridge 20 is ignited pushes the cartridge jacket 20b onto the inner circumferential surface of the cartridge receiving chamber 44 presses and automatically seals the muzzle area 18 of the barrel 12. All of the energy released when the cartridge 20 is ignited is used to accelerate the projectile 24. Due to the automatic sealing of the barrel 12, the gas pressure weapon 10 according to the invention can be constructed simply.

In Figur 8 ist eine weitere Ausführungsform der erfindungsgemäßen Gasdruckwaffe dargestellt, welche im wesentlichen der in den Figuren 1 bis 7 dargestellten Gasdruckwaffe entspricht. Analoge Teile sind in Figur 8 daher mit gleichen Bezugszeichen versehen wie in den Figuren 1 bis 7, jedoch vermehrt um die Zahl 100. Die Gasdruckwaffe gemäß Figur 8 wird im folgenden nur insoweit beschrieben werden als sie sich von der Gasdruckwaffe gemäß Figuren 1 bis 7 unterscheidet. Bezüglich der weiteren Bauteile und deren Funktionen wird hiermit ausdrücklich auf die Beschreibung der Figuren 1 bis 7 verwiesen.FIG. 8 shows a further embodiment of the gas pressure weapon according to the invention, which essentially corresponds to the gas pressure weapon shown in FIGS. 1 to 7. Analog parts in FIG. 8 are therefore provided with the same reference numerals as in FIGS. 1 to 7, but increased by the number 100. The gas pressure weapon according to FIG. 8 will only be described in the following to the extent that it differs from the gas pressure weapon according to FIGS. 1 to 7 . With regard to the other components and their functions, reference is hereby expressly made to the description of FIGS. 1 to 7.

Das Gasdruckgewehr 110 gemäß Figur 8 unterscheidet sich von dem Gasdruckgewehr 10 gemäß den Figuren 1 bis 7 lediglich dadurch, daß neben dem Magazin 146 für Kartuschen 120 auch ein Magazin 160 für Geschosse 124 vorgesehen ist, mit welchem die Geschosse 24 nacheinander in die Kartuschenaufnahmekammer 144 eingeführt werden können. Das Geschoß-Magazin 160 ist waagrecht, d.h. quer zur Laufrichtung, angeordnet. Das Magazin 160 weist eine Mehrzahl von Magazinbohrungen 162 auf, in denen jeweils ein Geschoß 124 aufgenommen ist und deren Innendurchmesser den gleichen Wert aufweist wie der Innendurchmesser φ44a des Hauptabschnitts 144a der Kartuschenaufnahmekammer 144.The gas pressure rifle 110 according to FIG. 8 differs from the gas pressure rifle 10 according to FIGS. 1 to 7 only in that, in addition to the magazine 146 for cartridges 120, a magazine 160 for projectiles 124 is also provided, with which the bullets 24 can be successively inserted into the cartridge receiving chamber 144. The projectile magazine 160 is arranged horizontally, that is to say transversely to the direction of travel. The magazine 160 has a plurality of magazine bores 162, in each of which a projectile 124 is received and whose inside diameter has the same value as the inside diameter φ 44a of the main section 144a of the cartridge receiving chamber 144.

Der einzige Unterschied beim Laden des Gasdruckgewehrs 110 im Vergleich zum Laden des Gasdruckgewehrs 10 besteht darin, daß das Geschoß 124 nicht von Hand in die Kartuschenaufnahmekammer 144 eingelegt wird, sondern mit Hilfe des Magazins eine Magazinbohrung 162 mit einem darin befindlichen Geschoß 124 in Fluchtung zu dem Hauptabschnitt 144a der Kartuschenaufnahmekammer 144 gebracht wird. Hierauf wird wie bei der Gasdruckwaffe 10 das Geschoß 124 mittels der Kartusche 120 in den Laufkanal 112d des Laufs 112 eingeführt und dabei an der Ringkante 144c kalibriert. Aufgrund der Gleichheit der Innendurchmesser der Magazinbohrung 162 und der Kartuschenaufnahmekammer 144 ist sichergestellt, daß der Schürzenabschnitt des Geschosses 124 beim Übergang Magazinbohrung/Kartuschenaufnahmekammer nicht verformt wird, sondern erst von der Ringkante 144c.The only difference when loading the gas pressure rifle 110 compared to loading the gas pressure rifle 10 is that the projectile 124 is not inserted into the cartridge receiving chamber 144 by hand, but rather, with the help of the magazine, a magazine bore 162 with a projectile 124 located therein in alignment with that Main portion 144a of the cartridge receiving chamber 144 is brought. Then, as with the gas pressure weapon 10, the projectile 124 is inserted into the barrel channel 112d of the barrel 112 by means of the cartridge 120 and is thereby calibrated at the ring edge 144c. Due to the equality of the inner diameter of the magazine bore 162 and the cartridge receiving chamber 144, it is ensured that the skirt portion of the projectile 124 is not deformed during the transition from the magazine bore / cartridge receiving chamber, but only from the ring edge 144c.

In Figur 9 ist schematisch eine dritte Ausführungsform der erfindungsgemäßen Gasdruckwaffe dargestellt,-welche im wesentlichen der in den vorstehenden Figuren dargestellten Gasdruckwaffe entspricht. Analoge Teile sind in Figur 9 daher mit gleichen Bezugszeichen versehen wie in den Figuren 1 bis 7, jedoch vermehrt um die Zahl 200. Die Gasdruckwaffe gemäß Figur 9 wird im folgenden nur insoweit beschrieben werden als sie sich von den vorstehend beschriebenen Gasdruckwaffen unterscheidet. Bezüglich der der weiteren Bauteile und deren Funktionen wird hiermit ausdrücklich auf die Beschreibung der Figuren 1 bis 7 verwiesen.FIG. 9 schematically shows a third embodiment of the gas pressure weapon according to the invention, which essentially corresponds to the gas pressure weapon shown in the previous figures. Analog parts in FIG. 9 are therefore provided with the same reference numerals as in FIGS. 1 to 7, but increased by the number 200. The gas pressure weapon according to FIG. 9 will only be described in the following to the extent that it differs from the gas pressure weapons described above. With regard to the other components and their functions, reference is hereby expressly made to the description of FIGS. 1 to 7.

Das Gasdruckgewehr 210 gemäß Figur 9 unterscheidet sich von dem Gasdruckgewehr 110 gemäß Figur 8 dadurch, daß anstelle des Magazins 160 für Geschosse 124 ein Magazin 270 vorgesehen ist, in welchem sowohl Geschosse 224 als auch Kartuschen 220 aufgenommen sind. Das Magazin 270 umfaßt eine Mehrzahl Magazinbohrungen 272. Die Magazinbohrungen 272 weisen jeweils einen ersten Abschnitt 272a auf, der der Kartuschenaufnahmekammer 44 der Ausführungsform gemäß den Figuren 1 bis 7 identisch ausgebildet ist, und ferner einen zweiten Abschnitt 272b, der dem glattzylindrischen Abschnitt 12c des Laufkanals 12d der Ausführungsform gemäß den Figuren 1 bis 7 identisch ausgebildet ist. Zwischen den ersten und zweiten Abschnitten 272a und 272b ist eine konische Ringkante 272c ausgebildet. In Schußrichtung schließt sich an das Magazin 270 unmittelbar ein mit Zügen versehener Abschnitt 112e der Laufkanals 112d an.The gas pressure rifle 210 according to FIG. 9 differs from the gas pressure rifle 110 according to FIG. 8 in that instead of the magazine 160 for storeys 124 a magazine 270 is provided, in which both storeys 224 and cartridges 220 are accommodated. The magazine 270 comprises a plurality of magazine bores 272. The magazine bores 272 each have a first section 272a, which is of identical design to the cartridge receiving chamber 44 of the embodiment according to FIGS. 1 to 7, and also a second section 272b, which corresponds to the smooth cylindrical section 12c of the running channel 12d of the embodiment according to FIGS. 1 to 7 is identical. A conical ring edge 272c is formed between the first and second sections 272a and 272b. In the weft direction, the magazine 270 is immediately followed by a section 112e of the running channel 112d, which is provided with trains.

Zum Laden des Magazins 270 wird zuerst ein Geschoß 224 von Hand in eine Magazinbohrung 272 eingelegt und gelangt mit seinem Schürzenabschnitt zur Anlage an der Ringkante 272c. Aufgrund der vorstehend beschriebenen Ausbildung des ersten Abschnitts 272a besteht hierbei nicht die Gefahr einer Verformung des Geschosses 224. Anschließend wird eine Kartusche 220 in den ersten Abschnitt 272a eingeführt. Diese zentriert das Geschoß 224 zunächst mit ihrem konischen Kopfabschnitt und schiebt es hierauf in den zweiten Abschnitt 272b der Magazinbohrung 272, wobei sie das Geschoß 224 an der Ringkante 272c kalibriert.To load the magazine 270, a projectile 224 is first inserted manually into a magazine bore 272 and its apron section comes to rest against the ring edge 272c. Because of the above-described design of the first section 272a, there is no risk of the projectile 224 being deformed. A cartridge 220 is then inserted into the first section 272a. This first centers the projectile 224 with its conical head section and then pushes it into the second section 272b of the magazine bore 272, calibrating the projectile 224 at the ring edge 272c.

Nach Abgabe eines Schusses aus der Magazinbohrung 272' wird das Magazin 270 in Richtung des Pfeils M verschoben, bis die nächste Magazinbohrung 272" in Flucht zu dem Laufkanal 212d gelangt. In der Magazinbohrung 272' verbleibt die abgeschossene Kartusche 220'. Zur Abgabe des nächsten Schusses schlägt das Schlagstück 222 auf den Rand des hinteren Endes der Kartusche 220" und zündet deren Treibmittelsatz (die Kartuschen 220 sind als Randzünder ausgebildet, wohingegen die Kartuschen 20 und 120 als Zentralzünder ausgebildet sind). Infolge der hieraus resultierenden Druckgasentwicklung wird das Geschoß 224" aus dem zweiten Abschnitt 272b heraus in den mit Zügen versehenen Abschnitt 112e des Laufkanals 112d beschleunigt.After a shot has been fired from the magazine bore 272 ', the magazine 270 is shifted in the direction of the arrow M until the next magazine bore 272 "is in alignment with the running channel 212d. The shot cartridge 220' remains in the magazine bore 272 ' Shot strikes the striking piece 222 on the edge of the rear end of the cartridge 220 ″ and ignites the propellant charge (the cartridges 220 are designed as edge detonators, whereas the cartridges 20 and 120 are designed as central igniters) are). As a result of the resulting pressure gas development, the projectile 224 "is accelerated out of the second section 272b into the section 112e of the running channel 112d provided with trains.

In Figur 10 ist eine vierte Ausführungsform der erfindungsgemäßen Gasdruckwaffe dargestellt, welche im wesentlichen der in den vorstehenden Figuren dargestellten Gasdruckwaffe entspricht. Analoge Teile sind in Figur 10 daher mit gleichen Bezugszeichen versehen wie in den Figuren 1 bis 7, jedoch vermehrt um die Zahl 300. Die Gasdruckwaffe gemäß Figur 10 wird im folgenden nur insoweit beschrieben werden als sie sich von den vorstehend beschriebenen Gasdruckwaffen unterscheidet. Bezüglich der der weiteren Bauteile und deren Funktionen wird hiermit ausdrücklich auf die Beschreibung der Figuren 1 bis 7 verwiesen.FIG. 10 shows a fourth embodiment of the gas pressure weapon according to the invention, which essentially corresponds to the gas pressure weapon shown in the preceding figures. Analog parts in FIG. 10 are therefore provided with the same reference numerals as in FIGS. 1 to 7, but increased by the number 300. The gas pressure weapon according to FIG. 10 will only be described in the following to the extent that it differs from the gas pressure weapons described above. With regard to the other components and their functions, reference is hereby expressly made to the description of FIGS. 1 to 7.

Die Gasdruckwaffe gemäß Figur 10 ist als Walzenrevolver 310 mit einem Trommelmagazin 380 ausgebildet, welches an dem Revolver 310 um eine in Längsrichtung des Laufs 312 angeordnete Achse 384 drehbar gelagert ist. Das Trommelmagazin 380 weist eine Mehrzahl Magazinbohrungen 382 auf, welche erste und zweite Abschnitte 382a und 382b aufweisen, die den ersten und zweiten Abschnitten 282a und 282b des Magazins 280 identisch ausgebildet sind. Die ersten und zweiten Abschnitte 382a und 382b sind über jeweilige konische Übergänge 382c verbunden.The gas pressure weapon according to FIG. 10 is designed as a roller turret 310 with a drum magazine 380 which is rotatably mounted on the turret 310 about an axis 384 arranged in the longitudinal direction of the barrel 312. The drum magazine 380 has a plurality of magazine bores 382 which have first and second sections 382a and 382b which are of identical design to the first and second sections 282a and 282b of the magazine 280. The first and second sections 382a and 382b are connected via respective conical junctions 382c.

Das Beladen des Magazins 380 mit Geschossen 324 und Kartuschen 320 und das Abfeuern der Waffe erfolgen auf die vorstehend am Beispiel der Gasdruckwaffe 210 beschriebene Weise. Auch bei dem Gasdruck-Revolver 310 werden randzündende Kartuschen 320 verwendet.The magazine 380 is loaded with bullets 324 and cartridges 320 and the weapon is fired in the manner described above using the example of the gas pressure weapon 210. Edge-firing cartridges 320 are also used in the gas pressure revolver 310.

Der Walzenrevolver kann ebenso mit einem Schwenkmagazin ausgebildet sein. Bei der Schwenkausführung müssen die abgeschossenen Kartuschen durch einen Ausstoßer manuell entfernt werden, während sie bei der Kippausführung durch das öffnen automatisch ausgestoßen werden.The roller turret can also be designed with a swivel magazine. In the swivel version, the shot cartridges must be removed manually using an ejector while they are automatically ejected by opening when tilting.

Ferner ist es möglich, die Gasdruckwaffe als Pistole mit einem Steckmagazin für Geschoß-Kartuschen-Einheiten auszubilden.It is also possible to design the gas pressure weapon as a pistol with a plug-in magazine for projectile-cartridge units.

Der Vorteil der automatischen Abdichtung des Laufs durch die mit einem elastischen Mantel ausgebildete Kartusche und des damit verbundenen einfachen Aufbaus der Gasdruckwaffe kann bspw. auch dann genutzt werden, wenn anstelle des Diabolo-Geschosses ein Medium zur Selbstverteidigung, bspw. eine Tränengaspatrone oder dergl., eingesetzt wird. Auch kann daran gedacht sein, die Gasdruckwaffe für den Heimwerkerbereich, die Schädlingsbekämpfung oder Sicherheitsanwendungen auszubilden.The advantage of the automatic sealing of the barrel through the cartridge formed with an elastic jacket and the associated simple construction of the gas pressure weapon can also be used, for example, if a medium for self-defense, e.g. a tear gas cartridge or the like, instead of the diabolo bullet. is used. It can also be considered to design the gas pressure weapon for the DIY sector, pest control or security applications.

Weiterhin kann die erfindungsgemäße Gasdruckwaffe gewichtsarm ausgebildet sein, da viele Bauteile aus Kunststoff, Aluminium oder dergl., hergestellt sein können.Furthermore, the gas pressure weapon according to the invention can be designed with low weight, since many components can be made of plastic, aluminum or the like.
