An extractor mechanism for the revolver with a conventional barrel includes an axis movable in the longitudinal direction of the barrel. The axle is connected to outwardly directed body contact arms, the body contact arms being made of a slightly resilient material. The extended ends of the case contact arms are shaped to project into a circumferential groove of the cartridge case. The cartridge or cartridge can thus be held in the ignition position. Likewise, the extractor can be operated in the usual way to convey the cases out of the drum.

Aus der Druckschrift US 5341587 ist ein weiterer Auswerfer mit Positioniermechanismus bekannt, der insbesondere die Verwendung unterschiedlich langer Patronen ermöglichen soll. Es ist vorgesehen, dass ein sich in Längsrichtung erstreckender Auswerferstab entlang seiner Längsachse relativ zu einem zentralen Bohrungsdurchgang der Trommel bewegt werden kann. Der Auszieherstern ist mit einem parallel zum Auswerferstab orientierten Federmechanismus verbunden. Andere Auszieher für einen Revolver sind aus US 2014/059912 A1 , EP 0 143 116 A1 und US 4 541 193 A bekannt.From the pamphlet US5341587 Another ejector with a positioning mechanism is known, which is intended in particular to enable the use of cartridges of different lengths. It is envisaged that a longitudinally extending ejector rod may be moved along its longitudinal axis relative to a central bore passage of the barrel. The ejector star is connected to a spring mechanism oriented parallel to the ejector rod. Other extractors for a revolver are out U.S. 2014/059912 A1 , EP 0 143 116 A1 and U.S. 4,541,193A known.

Der Erfindung liegt die Aufgabe zugrunde, einen Auszieher für einen Revolver bereitzustellen, der die Trommel im Bereich des Durchgangs eines Auszieherstabes nicht schwächt. Der Auszieher soll darüber hinaus eine Positionierung der Kartuschen ermöglichen. Dabei sollen sowohl Kartuschen mit Rand als auch randlose Kartuschen mit unterschiedlicher Länge verwendet werden können.The object of the invention is to provide an extractor for a revolver which does not weaken the barrel in the area where an extractor rod passes. The extractor should also allow the cartridges to be positioned. should both rimmed and rimless cartridges of different lengths can be used.

Die Erfindung ist eine Trommel mit Auszieher für einen Revolver zum Ausziehen von Kartuschen aus in der Trommel angeordneten Kartuschenkammern. Diese Erfindung ist in Anspruch 1 definiert.The invention is a drum with an extractor for a revolver for extracting cartridges from cartridge chambers arranged in the drum. This invention is defined in claim 1.

Der erfindungsgemäße Auszieher ist in der Trommel angeordnet. Er dient dazu, die nach dem Verschießen der Munition in den Kartuschenkammern verbleibenden Patronenhülsen hinauszubefördern. Dabei werden durch Verschieben der Auszieherstange mittels daran befestigtem Auszieherstern alle Patronenhülsen beziehungsweise Kartuschen zugleich ausgeworfen. Die Auszieher werden auch als Ausstoßer beziehungsweise Auswerfer bezeichnet.The extractor according to the invention is arranged in the drum. It is used to eject the cartridge cases remaining in the cartridge chambers after the ammunition has been fired. By moving the extractor rod using the extractor star attached to it, all cartridge cases or cartridges are ejected at the same time. The extractors are also referred to as ejectors or ejectors.

Ausgangspunkt der Erfindung ist ein Auszieher für einen Revolver zum Ausziehen von Kartuschen aus in der Trommel des Revolvers angeordneten Kartuschenkammern. Der Auszieher ist durch eine in der Nabe der Trommel angeordnete und mit einer Feder belastete Auszieherstange und einen daran befestigten mehrarmigen Auszieherstern gebildet. Der Auszieherstern mit seinen Ausziehersternarmen erstreckt sich dabei in radialer Richtung zur Orientierung der Auszieherstange. Weiterhin weisen die Ausziehersternarme Endabschnitte auf, die mit dem Mantel der Kartusche korrespondieren.The starting point of the invention is an extractor for a revolver for extracting cartridges from cartridge chambers arranged in the barrel of the revolver. The extractor is formed by an extractor rod which is arranged in the hub of the drum and is loaded with a spring and a multi-armed extractor star attached to it. The extractor star with its extractor star arms extends in the radial direction for the orientation of the extractor rod. Furthermore, the extractor star arms have end sections that correspond to the shell of the cartridge.

Erfindungsgemäß ist vorgesehen, dass der Auszieherstern als eine ebene Platte ausgebildet ist und die Ausziehersternarme des Ausziehersterns jeweils eine in radialer Richtung wirkende Ausziehersternarmfeder aufweisen, die durch die Endabschnitte der Ausziehersternarme des Ausziehersterns eine Bewegung der der Ausziehersternarme in radialer Richtung zur Auszieherstange bewirken.According to the invention, the extractor star is designed as a flat plate and the extractor star arms of the extractor star each have an extractor star arm spring acting in the radial direction, which causes a movement of the extractor star arms in the radial direction towards the extractor rod through the end sections of the extractor star arms of the extractor star.

Durch die derart ausgebildeten federnden Ausziehersternarme können sich diese in vorteilhafter Weise an den relevanten Durchmesser der jeweiligen Kartusche anpassen. Das heißt, dass die Endabschnitte der Ausziehersternarme bis an den Mantel der Kartusche bei umrandeten Kartuschen beziehungsweise in die umlaufende Kartuschennut der randlosen Kartuschen gedrückt werden können. Damit kann in vorteilhafter Weise ein formschlüssiger Kontakt zwischen den Ausziehersternarmen und den Kartuschen realisiert werden. Somit ist es möglich, dass durch die Bewegung des Ausziehers in Auszugsrichtung die Kartuschen aus den in der Trommel angeordneten Kartuschenkammern hinausbefördert werden.The spring-loaded extractor star arms designed in this way can advantageously adapt to the relevant diameter of the respective cartridge. This means that the end sections of the extractor star arms can be pressed up to the shell of the cartridge in the case of rimmed cartridges or into the circumferential cartridge groove of the rimless cartridges. In this way, a form-fitting contact between the extractor star arms and the cartridges can be realized in an advantageous manner. It is thus possible for the cartridges to be conveyed out of the cartridge chambers arranged in the drum by the movement of the extractor in the extraction direction.

Damit ist in vorteilhafter Weise eine flexible Anpassung aller Ausziehersternarme an die jeweilige Ausführung der verwendeten Kartusche möglich.A flexible adaptation of all extractor star arms to the respective design of the cartridge used is thus possible in an advantageous manner.

Somit kann der Auszieherstern in vorteilhafter Weise gleichzeitig für unterschiedliche Bauarten von Kartuschen verwendet werden, da sich jeder Ausziehersternarm an die jeweilige Kartusche anpasst.The extractor star can thus be used in an advantageous manner for different types of cartridges at the same time, since each extractor star arm adapts to the respective cartridge.

Durch die ebene Ausbildung des Ausziehersterns und die in den Ausziehersternarmen integrierten, in radialer Richtung wirkenden Federn müssen in vorteilhafter Weise keine entsprechenden Ausnehmungen in der Nabe der Trommel vorgesehen werden. Somit wird die Nabe der Trommel in vorteilhafter Weise nicht geschwächt und es muss weniger Material aus der Trommel entfernt werden.Due to the flat design of the extractor star and the springs that are integrated in the extractor star arms and act in the radial direction, no corresponding recesses have to be provided in the hub of the drum, which is advantageous. Thus, advantageously, the hub of the drum is not weakened and less material needs to be removed from the drum.

Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen.Further preferred configurations of the invention result from the remaining features mentioned in the dependent claims.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung besteht der Auszieherstern aus Federstahl.According to an advantageous embodiment of the invention, the extractor star consists of spring steel.

Die Feder, nachfolgend Ausziehersternarmfeder genannt, ist durch jeweils in die Ausziehersternarme eingebrachte Ausfräsungen realisiert. Die Ausfräsungen sind dabei quer zur radialen Richtung als auch quer zur Orientierung der Auszieherstange orientiert eingebracht.The spring, referred to below as the extractor star arm spring, is implemented by milling cuts in the extractor star arms. The cutouts are oriented transversely to the radial direction and also transversely to the orientation of the extractor rod.

Damit verbleibt zwischen den Ausfräsungen ein mäanderartiger oder Z-förmiger Abschnitt des Ausziehersterns, der die Federwirkung in vorteilhafter Weise realisiert.A meandering or Z-shaped section of the extractor star thus remains between the milled-out portions, which implements the spring effect in an advantageous manner.

Der Auszieherstern ist entsprechend einfach herstellbar. Es müssen keine separaten Federn einschließlich Führung montiert werden. Der Platzbedarf ist gering und die Zuverlässigkeit der federnden Ausziehersternarme ist hoch.The extractor star is correspondingly easy to produce. There is no need to mount separate springs including the guide. The space required is small and the reliability of the spring-loaded extractor star arms is high.

In bevorzugter Ausgestaltung der Erfindung ist die Ausziehersternarmfeder so ausgebildet, dass der Federweg der Ausziehersternarmfeder der Tiefe einer an einer randlosen Kartusche umlaufenden Kartuschennut entspricht. Damit können sich die Endabschnitte der Ausziehersternarme durch den Federweg in vorteilhafter Weise an die beiden relevanten Kartuschendurchmesser anpassen.In a preferred embodiment of the invention, the extractor star arm spring is designed in such a way that the spring deflection of the extractor star arm spring corresponds to the depth of a cartridge groove running around a rimless cartridge. The end sections of the extractor star arms can thus advantageously adapt to the two relevant cartridge diameters due to the spring deflection.

Entsprechend einer bevorzugten Ausgestaltung der Erfindung ist die Auszieherstange mit einem sich in radialer Richtung erstreckenden Verschlussplättchen verbunden, wobei der Auszieherstern auf der Auszieherstange verschiebbar angeordnet ist, während das Verschlussplättchen in Ausziehrichtung vor dem Auszieherstern angeordnet ist.According to a preferred embodiment of the invention, the extractor rod is connected to a locking plate extending in the radial direction, the extractor star being arranged displaceably on the extractor rod, while the locking plate being arranged in front of the extractor star in the extraction direction.

Das Verschlussplättchen ist erfindungsgemäss mit Stiften versehen, wobei jeder Stift jeweils einem Ausziehersternarm zugeordnet ist und die Stifte in Ausziehrichtung orientiert sind.According to the invention, the closure plate is provided with pins, each pin being assigned to an extractor star arm and the pins being oriented in the extraction direction.

Die Stifte sind in der Weise angeordnet, dass je Ausziehersternarm ein Stift mit mindestens einer, vorzugsweise zwei, im Ausziehersternarm zwischen der Ausziehersternarmfeder und den Endabschnitten der Ausziehersternarme angeordneten Positionierungsbohrungen zusammenwirkt.The pins are arranged in such a way that one pin per extractor star arm interacts with at least one, preferably two, positioning bores arranged in the extractor star arm between the extractor star arm spring and the end sections of the extractor star arms.

Die Positionierungsbohrungen sind entsprechend gleichfalls in Ausziehrichtung orientiert. Der Abstand der jeweils in radialer Richtung zueinander angeordneten Positionierungsbohrungen eines Ausziehersternarms entspricht der Tiefe der umlaufenden Kartuschennut.The positioning holes are also oriented accordingly in the pull-out direction. The distance between the positioning bores of an extractor star arm, which are arranged in the radial direction relative to one another, corresponds to the depth of the circumferential cartridge groove.

Durch die Bewegung der mit dem Verschlussplättchen verbundenen Auszieherstange werden die Stifte des Verschlussplättchens in den auf der Auszieherstange über den Weg verschiebbar angeordneten Auszieherstern in die in den Ausziehersternarmen angeordneten Positionierungsbohrungen geschoben.The movement of the extractor rod connected to the locking plate pushes the pins of the locking plate in the extractor star, which is arranged to be movable along the path on the extractor bar, into the positioning bores arranged in the extractor star arms.

Die zwei Positionierungsbohrungen ermöglichen in vorteilhafter Weise die Arretierung des jeweiligen Ausziehersternarms in zwei Positionen- einer ersten Position, bei der die Endabschnitte des jeweiligen Ausziehersternarms am Mantel einer umrandeten Kartusche anliegen und einer zweiten Position, bei der die Endabschnitte des Ausziehersternarms in die Kartuschennut einer randlosen Kartusche ragen.The two positioning bores advantageously allow the respective extractor star arm to be locked in two positions- a first position in which the end sections of the respective extractor star arm rest against the casing of a rimmed cartridge and a second position in which the end sections of the extractor star arm fit into the cartridge groove of a rimless cartridge protrude.

Damit können die federnden Ausziehersternarme entsprechend in vorteilhafter Weise so fixiert werden, dass sie in einer ersten Position am Mantel der Kartusche beziehungsweise in einer zweiten Position in der umlaufenden Kartuschennut anliegend arretierbar sind.In this way, the spring-loaded extractor star arms can advantageously be fixed in such a way that they can be locked in a first position on the shell of the cartridge or in a second position in the circumferential cartridge groove.

Der Federweg wird durch die Arretierung entsprechend begrenzt und die Position der Endabschnitte somit an den gerade relevanten Kartuschendurchmesser des Mantels beziehungsweise des Kartuschennutinnendurchmessers angepasst. Die Feder realisiert die Anpassung an den relevanten Durchmesser und die Stifte mit den Positionierungsbohrungen sorgen für die Fixierung des jeweiligen Ausziehersternarms beim Verschieben des Ausziehersterns zum Ausziehen der Kartusche.The spring deflection is correspondingly limited by the locking and the position of the end sections is thus adapted to the currently relevant cartridge diameter of the jacket or the inside diameter of the cartridge groove. The spring realizes that Adaptation to the relevant diameter and the pins with the positioning holes ensure that the respective extractor star arm is fixed when the extractor star is moved to extract the cartridge.

Damit wird in vorteilhafter Weise verhindert, dass die Ausziehersternarme beim Ausziehen aufgrund der abgerundeten Nut randloser Kartuschen zurückweichen und so die Kartusche in der Trommel verbleiben würden. Außerdem wird in vorteilhafter Weise verhindert, dass sich die Kartuschen beim Ausziehen aus den Kartuschenkammern verkanten.This advantageously prevents the extractor star arms from receding when being pulled out due to the rounded groove of rimless cartridges and the cartridge would remain in the drum. In addition, it is advantageously prevented that the cartridges cant when being pulled out of the cartridge chambers.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist in Ausziehrichtung nach dem Auszieherstern eine Ratsche mit der Auszieherstange verbunden. Die Ratsche als bekanntes Bauteil eines Revolvers bewirkt nach der Betätigung des Abzugs die Drehung der Trommel in der Weise, dass die nächste Kartusche nach dem Verschießen einer Kartusche mit dem Lauf in eine Flucht gebracht wird.According to an advantageous embodiment of the invention, a ratchet is connected to the extractor rod after the extractor star in the extraction direction. The ratchet, a well-known component of a revolver, causes the drum to rotate after the trigger is actuated in such a way that the next cartridge after a cartridge has been fired is aligned with the barrel.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung sind die Endabschnitte der Ausziehersternarme mit einer Fase oder einer mit der Kartuschennut korrespondierenden Kontur versehen.According to a further preferred embodiment of the invention, the end sections of the extractor star arms are provided with a chamfer or a contour that corresponds to the cartridge groove.

Die mit der Fase realisierte Anschrägung der Endabschnitte der Ausziehersternarme erleichtert das Einschieben der Kartuschen. Die Kontur der Endabschnitte korrespondiert vorzugsweise mit der Form der Kartuschennut einer randlosen Kartusche, so dass der Formschluss verbessert wird und damit ein sicheres Ausziehen der Kartuschen, auch bei geringer Kartuschennuttiefe, möglich ist.The beveling of the end sections of the star-shaped extractor arms, realized with the chamfer, facilitates the insertion of the cartridges. The contour of the end sections preferably corresponds to the shape of the cartridge groove of a rimless cartridge, so that the form fit is improved and safe extraction of the cartridge is possible, even with a small cartridge groove depth.

Die Erfindung wird nachfolgend in Ausführungsbeispielen anhand der zugehörigen Zeichnungen erläutert. Es zeigen:

Figur 1 zeigt einen an sich bekannten Revolver in der Seitenansicht. Der Revolver umfasst eine drehbare Trommel 1 mit Kartuschenkammern (nicht dargestellt), in denen die Kartuschen (nicht dargestellt) angeordnet sind. Die Kartuschen können durch Drehen der Trommel 1 in eine Flucht mit dem Lauf 15 gebracht werden. Durch die Betätigung der Auszieherstange 2, 7 in Ausziehrichtung AR können die Kartuschen, also vorzugsweise die nach dem Verschießen verbleibenden Patronenhülsen, aus der Kartuschenkammer der Trommel 1 befördert werden. figure 1 shows a known revolver in side view. The revolver comprises a rotatable drum 1 with cartridge chambers (not shown) in which the cartridges (not shown) are arranged. The cartridges can be aligned with the barrel 15 by rotating the drum 1 . By actuating the extractor rod 2, 7 in the extraction direction AR, the cartridges, ie preferably the cartridge cases remaining after firing, can be conveyed out of the cartridge chamber of the drum 1.

Die Auszieherstange 2 beziehungsweise die Achsenstange 7 (vergleiche Figuren 2, 3, 6, 7) der Auszieherstange 2 bildet zugleich die Drehachse für die Trommel 1.The extractor rod 2 or the axle rod 7 (cf figures 2 , 3 , 6, 7 ) of the extractor bar 2 also forms the axis of rotation for the drum 1.

In Figur 2 ist eine Ansicht der Trommel 1 mit dem Auszieherstern 4 von der Rückseite her dargestellt. Die Ansicht ist entsprechend entgegen der Ausziehrichtung in Schussrichtung orientiert.In figure 2 a view of the drum 1 with the extractor star 4 is shown from the rear. The view is accordingly oriented in the direction opposite to the pull-out direction in the weft direction.

Die Auszieherstange 2 beziehungsweise die Achsenstange 7 (vergleiche Figuren 3, 6, 7) der Auszieherstange 2 ist mit dem sechsarmigen ebenen, plattenförmigen Auszieherstern 4 auf einer vorgebbaren Länge (vergleiche Figur 7) über einen ersten Weg X1 verschiebbar verbunden.The extractor rod 2 or the axle rod 7 (cf Figures 3 , 6, 7 ) of the extractor rod 2 is connected to the six-armed flat, plate-shaped extractor star 4 at a predeterminable length (cf figure 7 ) slidably connected via a first path X1.

Die Ausziehersternarme 20 des Ausziehersterns 4 sind, bezogen auf die Auszieherstange 2, 7 in radialer Richtung (R), federnd ausgeführt.The extractor star arms 20 of the extractor star 4 are designed to be resilient in the radial direction (R) in relation to the extractor rod 2, 7.

Die Ausziehersternarme 20 ragen mit ihren Endabschnitten 16 in die in der Trommel 1 angeordneten Kartuschenkammern 17, in denen die Kartuschen 18 platziert werden, hinein.The extractor star arms 20 protrude with their end sections 16 into the cartridge chambers 17 arranged in the drum 1, in which the cartridges 18 are placed.

Zur Realisierung der Federung sind in den Ausziehersternarmen 20 Ausfräsungen 22 vorgesehen, so dass in diesem Bereich die Ausziehersternarme 20 mäanderförmig beziehungsweise Z-förmig ausgebildet sind. Auf diese Weise sind erfindungsgemäß die Ausziehersternarmfedern 19 in vorteilhafter Weise in den Ausziehersternarme 20 integriert (vergleiche Figur 2). Somit kann der Auszieherstern 4 aus einer entsprechenden Federstahlplatte einfach hergestellt werden.Millings 22 are provided in the extractor star arms 20 to implement the suspension, so that the extractor star arms 20 are designed in a meandering or Z-shape in this area. In this way, according to the invention Extractor star arm springs 19 are advantageously integrated into the extractor star arms 20 (cf figure 2 ). Thus, the extractor star 4 can be easily manufactured from a corresponding spring steel plate.

Die Endabschnitte 16 der Ausziehersternarme 20 werden durch die Ausziehersternarmfedern 19 entsprechend an den Mantel der umrandeten Kartuschen 18 herangedrückt beziehungsweise bei randlosen Kartuschen 18 in eine Kartuschennut 21 (vergleiche Figuren 3, 6, 7) geschoben.The end sections 16 of the extractor star arms 20 are pressed accordingly by the extractor star arm springs 19 against the casing of the bordered cartridges 18 or, in the case of rimless cartridges 18, into a cartridge groove 21 (cf Figures 3 , 6, 7 ) pushed.

Damit wird der formschlüssige Kontakt der Endabschnitte16 der Ausziehersternarme 20 zu den Kartuschen 18 realisiert und somit das Ausstoßen der Kartuschen 18 in Ausziehrichtung AR über den zweiten Weg X2, dem sogenannten Ausziehweg ermöglicht (vergleiche Figur 3).This achieves the form-fitting contact of the end sections 16 of the extractor star arms 20 with the cartridges 18 and thus enables the cartridges 18 to be ejected in the extraction direction AR via the second path X2, the so-called extraction path (cf figure 3 ).

In die Ausziehersternarme 20 des Ausziehersterns 4 sind jeweils zwei in radialer Richtung R zueinander angeordnete Positionierungsbohrungen 5 eingebracht.In each case two positioning bores 5 arranged in the radial direction R relative to one another are introduced into the extractor star arms 20 of the extractor star 4 .

Die Positionierungsbohrungen 5 dienen zur Aufnahme der in den Figuren 3 bis 7 dargestellten, im Verschlussplättchen 3 befestigten und in Ausziehrichtung AR orientierten Stifte 8.The positioning holes 5 are used to hold the Figures 3 to 7 shown, fastened in the locking plate 3 and oriented in the pull-out direction AR 8.

Durch die beiden, in radialer Richtung R angeordneten Positionierungsbohrungen 5 können die Ausziehersternarme 20 in Abhängigkeit der Art der Kartuschen 18 in zwei unterschiedlichen Arretierungspositionen arretiert werden. Eine erste Arretierungsposition entspricht der Verwendung von umrandeten Kartuschen 18, wobei die Endabschnitte 16 der Ausziehersternarme 20 jeweils am Mantel der Kartuschen 18 anliegen. Die zweite Arretierungsposition ist bei der Verwendung von randlosen Kartuschen 18 mit umlaufender Kartuschennut 21 relevant. Hier ragen die Endabschnitte 16 der Ausziehersternarme 20 in die umlaufende Kartuschennut 21 hinein (vergleiche auch Figuren 6 und 7).Due to the two positioning bores 5 arranged in the radial direction R, the extractor star arms 20 can be locked in two different locking positions depending on the type of cartridge 18 . A first locking position corresponds to the use of cartridges 18 with a border, with the end sections 16 of the extractor star arms 20 each lying against the casing of the cartridges 18 . The second locking position is relevant when using rimless cartridges 18 with a circumferential cartridge groove 21 . Here the end sections 16 of the extractor star arms 20 protrude into the circumferential cartridge groove 21 (compare also Figures 6 and 7 ).

Am Auszieherstern 4 ist weiterhin eine Ratschenvorrichtung 6 angeordnet. Die Ratschenvorrichtung 6 als separates Teil ist nur in einer Prinzipdarstellung gezeigt. Die Ratschenvorrichtung 6 dient zur Drehung der Trommel 1, wobei die Drehung durch den Auslöser jeweils nach dem Verschießen einer Kartusche 18 ausgelöst wird, so dass die jeweils nächste Kartusche 18 in eine Flucht mit dem Lauf 15 (vergleiche Figur 1) gebracht wird.A ratchet device 6 is also arranged on the star extractor 4 . The ratchet device 6 as a separate part is only shown in a schematic representation. The ratchet device 6 is used to rotate the drum 1, with the rotation being triggered by the trigger each time a cartridge 18 has been fired, so that the next cartridge 18 in each case is aligned with the barrel 15 (cf figure 1 ) is brought.

Die Figur 3 zeigt eine Längsschnittdarstellung durch die Trommel 1 des Revolvers mit dem an der Auszieherstange 2 befestigten Verschlussplättchen 3 und dem verschiebbar auf der Auszieherstange 2 befestigten Auszieherstern 4. Die Figuren 6 und 7 zeigen dabei Details aus Figur 3, die das Zusammenwirken des Verschlussplättchens 3 mit den daran befestigten Stiften 8 und dem Auszierstern 4 mit den jeweils in den Ausziehersternarmen 20 in Ausziehrichtung AR angeordneten beiden Positionierungsbohrungen 5i, 5a veranschaulichen.The figure 3 shows a longitudinal section through the barrel 1 of the revolver with the locking plate 3 attached to the extractor rod 2 and the slideable on the Extractor rod 2 attached extractor star 4. The Figures 6 and 7 show details figure 3 , which illustrate the interaction of the closure plate 3 with the pins 8 fastened thereto and the extracting star 4 with the two positioning bores 5i, 5a arranged in the extracting star arms 20 in the extraction direction AR.

In Figur 3 ist das Verschlussplättchen 3, das mittels Gewinde 10 mit der Auszieherstange 2 beziehungsweise mit einer mit der Auszieherstange 2 verschraubten Achsenstange 7 verbunden ist, dargestellt.In figure 3 the closure plate 3, which is connected by means of a thread 10 to the extractor rod 2 or to an axle rod 7 screwed to the extractor rod 2, is shown.

Im Ruhezustand ist das Verschlussplättchen 3 in einer kleinen Ausnehmung 11 des Nabenbereiches der Trommel 1 positioniert.In the resting state, the closure plate 3 is positioned in a small recess 11 in the hub area of the drum 1.

Auf dem Verschlussplättchen 3 sind in Ausziehrichtung AR orientierte Stifte 8 in Richtung der Ausziehersternarme 20 angeordnet.Pins 8 oriented in the direction of extraction AR are arranged on the closure plate 3 in the direction of the extractor star arms 20 .

Die Auszieherstange 2 ist durch den sechsarmigen Auszieherstern 4 hindurch auf dem ersten Weg X1, der etwas länger als die Länge der Stifte 8 ist, in Ausziehrichtung AR verschiebbar geführt.The extractor rod 2 is guided displaceably in the extraction direction AR through the six-armed extractor star 4 along the first path X1, which is slightly longer than the length of the pins 8.

Entsprechend der in den Kartuschenkammern 17 der Trommel 1 platzierten Kartuschen 18 drücken sich durch die hier nur symbolisch dargestellten Ausziehersternarmfedern 19 die Endabschnitte 16 der Ausziehersternarme 20 an den Mantel beziehungsweise in die Kartuschennut 21 der jeweiligen Kartusche 18.Corresponding to the cartridges 18 placed in the cartridge chambers 17 of the drum 1, the end sections 16 of the extractor star arms 20 are pressed against the jacket or into the cartridge groove 21 of the respective cartridge 18 by the extractor star arm springs 19, which are only shown symbolically here.

Damit passen sich die jeweiligen Ausziehersternarme 20 an die jeweils zugeordnete Kartusche 18 an.The respective extractor star arms 20 thus adapt to the respectively associated cartridge 18 .

Die Darstellungen in den Figuren 3 und 6 zeigen den Ruhezustand. Das Verschlussplättchen 3 mit den daran befestigten Stiften 8 liegt den Ausziehersternarmen 20 mit den Positionierungsbohrungen 5i, 5a gegenüber.The depictions in the Figures 3 and 6 show the idle state. The locking plate 3 with the pins 8 fastened to it lies opposite the extractor star arms 20 with the positioning bores 5i, 5a.

Konkret ist hier der jeweilige Stift 8 der jeweils äußeren Positionierungsbohrung 5a gegenüber angeordnet. Die Ausziehersternarmfedern 19 sind in Figur 6 zusammengedrückt. Somit liegen die Endabschnitte 16 der Ausziehersternarme 20 am Mantel der Kartusche 18 beziehungsweise in der Kartuschennut 21 (vergleiche Figur 3) an.Specifically, the respective pin 8 is arranged opposite the respective outer positioning bore 5a. The extractor star arm springs 19 are in figure 6 pressed together. Thus, the end sections 16 of the extractor star arms 20 lie on the casing of the cartridge 18 or in the cartridge groove 21 (cf figure 3 ) at.

Dabei entspricht ein Federweg Y der Ausziehersternarmfedern 19 in radialer Richtung (R) (vergleiche Figur 7) zur Ausziehrichtung AR dem Abstand der beiden Positionierungsbohrungen 5i, 5a.A spring deflection Y of the extractor star arm springs 19 in the radial direction (R) (cf figure 7 ) to the extraction direction AR the distance between the two positioning holes 5i, 5a.

Durch die Betätigung der Auszieherstange 2, 7 in Ausziehrichtung AR um den ersten Weg X1 wird das Verschlussplättchen 3 gegen den Auszieherstern 4 geschoben, wodurch die Stifte 8 des Verschlussplättchens 3 in jeweils eines der beiden Positionierungslöcher 5i, 5a des Ausziehersternarms 20 gedrückt und diese somit arretiert werden.By actuating the extractor rod 2, 7 in the extraction direction AR by the first distance X1, the locking plate 3 is pushed against the extractor star 4, as a result of which the pins 8 of the locking plate 3 are pressed into one of the two positioning holes 5i, 5a of the extractor star arm 20 and thus arrest them become.

In Figur 7 ist die arretierte Position der Ausziehersternarme 20 gezeigt. Hier ragen die Endabschnitte 16 der Ausziehersternarme 20 in die umlaufende Kartuschennut 21 einer randlosen Kartusche 18 (vergleiche Figur 3).In figure 7 the locked position of the extractor star arms 20 is shown. Here the end sections 16 of the extractor star arms 20 protrude into the circumferential cartridge groove 21 of a rimless cartridge 18 (cf figure 3 ).

In dieser Position sind die Ausziehersternarme 20 somit arretiert. Die Arretierung erfolgt durch das Heranschieben der Auszieherstange 2, 7 mit dem Verschlussplättchen 3 an den Auszieherstern 4 um den ersten Weg X1, so dass die Stifte 8 in eine der Positionierungsbohrungen 5a, 5i - hier in die Positionierungsbohrung 5i - ragen. Damit erfolgt durch die Arretierung die Aufhebung der Wirkung der Ausziehersternarmfedern 19.The extractor star arms 20 are thus locked in this position. It is locked by pushing the extractor rod 2, 7 with the locking plate 3 on the extractor star 4 by the first distance X1, so that the pins 8 protrude into one of the positioning bores 5a, 5i—in this case, into the positioning bore 5i. The effect of the extractor star arm springs 19 is thus canceled by the locking.

Wenn die Stifte 8 in die äußeren Positionierungslöcher 5i ragen, erfolgt die Arretierung der Ausziehersternarme 20 in der am Mantel der umrandeten Kartuschen 2 anliegenden Position.When the pins 8 protrude into the outer positioning holes 5i, the extractor star arms 20 are locked in the position resting against the casing of the rimmed cartridges 2.

Die inneren Positionierungslöcher 5i dienen der Arretierung der Ausziehersternarme 20 in der Nut randloser Kartuschen 2. Mit anderen Worten, wenn die Stifte 8 in die inneren Positionierungslöcher 5i ragen, erfolgt die Arretierung der Ausziehersternarme 20 in der Nut randloser Kartuschen 2.The inner positioning holes 5i serve to lock the extractor star arms 20 in the groove of rimless cartridges 2. In other words, when the pins 8 protrude into the inner positioning holes 5i, the extractor star arms 20 are locked in the groove of rimless cartridges 2.

Somit werden mittels des Federwegs Y der Ausziehersternarmfedern 19 in radialer Richtung (R) (vergleiche Figur 7) zur Ausziehrichtung AR in vorteilhafter Weise zwei arretierbare Positionen der Stifte 8 gewährleistet.Thus, by means of the spring deflection Y of the extractor star arm springs 19 in the radial direction (R) (cf figure 7 ) for the pull-out AR advantageously ensures two lockable positions of the pins 8 .

Mit anderen Worten die zwei Positionierungsbohrungen 5a, 5i ermöglichen in vorteilhafter Weise die Arretierung des jeweiligen Ausziehersternarms 20 in zwei Positionen, einer - ersten Position -, bei der die Endabschnitte 16 des jeweiligen Ausziehersternarms 20 am Mantel einer umrandeten Kartusche anliegen und einer - zweiten Position - , bei der die Endabschnitte 16 des jeweiligen Ausziehersternarms 20 in die Kartuschennut 21 einer randlosen Kartusche ragen.In other words, the two positioning bores 5a, 5i advantageously allow the respective extractor star arm 20 to be locked in two positions, one--first position--in which the end sections 16 of the respective extractor star arm 20 rest against the casing of a bordered cartridge and one--second position-- , in which the end sections 16 of the respective extractor star arm 20 protrude into the cartridge groove 21 of a rimless cartridge.

Nachfolgend wird durch das Fortsetzen der Bewegung um den zweiten Weg X2 der Auszieherstange 2, 7 in Ausziehrichtung AR die Kartusche 18 aus der Kartuschenkammer 17 hinausgeschoben (vergleiche Figur 3).The cartridge 18 is then pushed out of the cartridge chamber 17 by continuing the movement around the second path X2 of the extractor rod 2, 7 in the extraction direction AR (cf figure 3 ).

Nach dem Ausstoßen der Kartusche 18 wird die Auszieherstange 2 mit dem Verschlussplättchen 3 durch die an der Auszieherstange 2 angeordnete Druckfeder 13 mit Gegenlager in der Trommel 1 in die Ruheposition (vergleiche Figur 3 und 6) zurückgezogen.After the cartridge 18 has been ejected, the ejector rod 2 with the closure plate 3 is moved into the rest position by the compression spring 13 arranged on the ejector rod 2 with a counter bearing in the drum 1 (cf figure 3 and 6 ) withdrawn.

Vorzugsweise sind die Endabschnitte16 der Ausziehersternarme 20 angefast, um ein leichtes Einführen der Kartuschen 18 in die Kartuschenkammer 17 zu ermöglichen. Vorzugsweise weisen die Endabschnitte 16 eine Kontur auf, die mit der umlaufenden Kartuschennut 21 korrespondiert.The end sections 16 of the extractor star arms 20 are preferably chamfered in order to enable the cartridges 18 to be easily inserted into the cartridge chamber 17 . The end sections 16 preferably have a contour which corresponds to the circumferential cartridge groove 21 .

In Figur 4 ist ein Verschlussplättchen 3 als Einzelteil in Seitenansicht dargestellt.In figure 4 a closure plate 3 is shown as an individual part in a side view.

Das Verschlussplättchen 3 ist scheibenförmig ausgebildet. Auf dem Verschlussplättchen 3 sind am äußeren Rand senkrecht stehend die Stifte 8 angeordnet, wobei jedem Ausziehersternarm 20 ein Stift 8 zugeordnet ist. Die Stifte 8 sind angefast, insbesondere spitz zulaufend, um beim Heranschieben an den Auszieherstern (nicht dargestellt) leicht in die dort angeordneten Positionierlöcher (nicht dargestellt) geschoben werden zu können.The closure plate 3 is disc-shaped. The pins 8 are arranged vertically on the outer edge of the closure plate 3 , with each extractor star arm 20 being assigned a pin 8 . The pins 8 are chamfered, in particular tapering to a point, in order to be able to be pushed easily into the positioning holes (not shown) arranged there when pushed up to the star extractor (not shown).

In der Mitte ist eine Bohrung mit Innengewinde 10 zur Befestigung des Verschlussplättchens 3 an der Auszieherstange (nicht dargestellt) vorgesehen.In the middle there is a hole with an internal thread 10 for fastening the closure plate 3 to the extractor rod (not shown).

Figur 5 zeigt ein Verschlussplättchen 3 in einer Einzelteilansicht entgegen der Ausziehrichtung mit den am Rand angeordneten Stiften 8. figure 5 shows a closure plate 3 in an individual view against the pull-out direction with the pins 8 arranged on the edge.

In der Mitte ist eine Bohrung mit Innengewinde 10 zur Befestigung des Verschlussplättchens 3 an der Auszieherstange 2 (nicht dargestellt) vorgesehen.A hole with an internal thread 10 for fastening the closure plate 3 to the extractor rod 2 (not shown) is provided in the middle.
