Description

Die vorliegende Erfindung betrifft eine Verschlusseinrichtung für Schusswaffen, insbesondere für Repetiergewehre, umfassend ein Patronenlager, eine außenliegende Hülse und eine in dieser aufgenommene Kammer, wobei die Kammer in dem dem Patronenlager zugewandten Bereich einen Verschlusskopf aufweist und innerhalb der Kammer ein Steuerstück gegenüber der Kammer und gegenüber dem Verschlusskopf axial verschieblich gelagert ist, weiterhin umfassend einen Kammerhebel, welcher mit dem Steuerstück verbunden ist, so dass bei einer Rückwärtsbewegung des Kammerhebels der Verschlusskopf entriegelt und beim Fortlauf verriegelt wird, wobei der Kammerhebel im hinteren Endbereich der Hülse schwenkbar angebracht ist und der Kammerhebel um eine Achse schwenkbar gelagert ist, welche außermittig zur Längsachse der Kammer verläuft.The present invention relates to a locking device for firearms, in particular for repeating rifles, comprising a cartridge chamber, an outer sleeve and a chamber accommodated therein, the chamber having a locking head in the region facing the cartridge chamber and a control piece in the chamber opposite and opposite the locking head is axially displaceably mounted, further comprising a chamber lever which is connected to the control piece, so that when the chamber lever is moved backwards, the closing head is unlocked and locked as it progresses, the chamber lever being pivotably mounted in the rear end region of the sleeve and the chamber lever around an axis is pivotally mounted, which extends eccentrically to the longitudinal axis of the chamber.

Aus der DE 196 08 872 C1 ist eine Verschlusseinrichtung für Schusswaffen, insbesondere für Repetiergewehre, bekannt mit einem Patronenlager, mit einer außenliegenden Hülse und einer in dieser aufgenommenen Kammer, wobei die Kammer in dem dem Patronenlager zugewandten Bereich einen Verschlusskopf aufweist und innerhalb der Kammer ein Steuerstück gelagert ist, so dass bei der Rückwärtsbewegung des Kammerhebels der Verschlusskopf entriegelt und beim Fortlauf verriegelt wird. Bei dieser bekannten Verschlusseinrichtung ist jedoch der Verschlusskopf nicht drehbar gelagert. Die Verriegelung geschieht über Verriegelungselemente in Form von Kugeln, die über eine abgeschrägte vordere Stirnfläche des Steuerstücks bei dessen Vorschieben nach außen an die Innenwand der Verschlusshülse gedrückt werden. Der Kammerhebel hat zwar bei dieser Waffe eine günstige hintere Position, aber die Verriegelung über die genannten Kugeln hat sich in der Praxis als nachteilig erwiesen.From the DE 196 08 872 C1 is a locking device for firearms, in particular for repeating rifles, known with a cartridge chamber, with an outer sleeve and a chamber accommodated therein, the chamber in the area facing the cartridge chamber has a breech head and a control piece is mounted within the chamber, so that at The locking head is unlocked during the backward movement of the chamber lever and locked as it continues. In this known closure device, however, the closure head is not rotatably mounted. The locking takes place via locking elements in the form of balls which are pressed outwards against the inner wall of the closure sleeve via a bevelled front end face of the control piece when it is pushed forward. The chamber lever has a favorable rear position in this weapon, but the locking via the bullets mentioned has proven disadvantageous in practice.

In der EP 0 784 194 A2 wird ein Geradzugverschluss für eine Schusswaffe beschrieben, bei dem der Verschlusskopf in einer Kammer drehbar um die eigene Achse gelagert und durch einen Absatz gegenüber der Kammer in seiner Axialbewegung fixiert ist. Eine Steuerhülse weist an ihrer Vorderseite einen Steuerbolzen auf, dessen Oberfläche im Kontakt mit einer Steuernut ist. Bei dieser Schusswaffe befindet sich der Kammergriff konstruktionsbedingt am vorderen Ende es Verschlusses. Diese vordere Position des Kammergriffes erschwert die Handhabung und eine schnelle Waffenfunktion.In the EP 0 784 194 A2 describes a straight-draw breech for a firearm, in which the breech head is rotatably mounted about its own axis in a chamber and its axial movement is fixed by a shoulder opposite the chamber. A control sleeve has a control pin on its front, the surface of which is in contact with a control groove. With this firearm the design of the bolt handle is at the front end of the breech. This front position of the chamber handle makes handling and a quick weapon function difficult.

Aus der DE 43 05 700 C1 ist ebenfalls ein Verschluss für eine Schusswaffe bekannt geworden, bei der sich der Geradzughebel direkt über dem Abzug befindet und aufgrund dieser Position eine gute Handhabung erlaubt. Die Verriegelung erfolgt hier jedoch über eine aufspreizbare Hülse, die nicht immer zuverlässig ist.
Bei allen drei vorgenannten bekannten Lösungen weisen die Verschlüsse jeweils nur einen vergleichsweise kurzen Hub des Steuerstücks auf, was durch die Lage der Hebelachse und den Kontaktpunkt mit dem Steuerstück bestimmt ist. Der Hub liegt nur bei etwa 8- 10 mm, was nur eine Verriegelung mit aufspreizbarer Hülse, Kugeln oder begrenzter Drehung in einem Drehwinkel von beispielsweise bis zu etwa 20 ° ermöglicht.From the DE 43 05 700 C1 A breech for a firearm has also become known in which the straight lever is located directly above the trigger and allows good handling due to this position. The locking takes place here via an expandable sleeve, which is not always reliable.
In all three aforementioned known solutions, the closures each have only a comparatively short stroke of the control piece, which is determined by the position of the lever axis and the point of contact with the control piece. The stroke is only about 8-10 mm, which only allows locking with an expandable sleeve, balls or limited rotation at an angle of rotation of up to about 20 °, for example.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Verschluss, insbesondere einen Geradzugverschluss, für eine Schusswaffe mit den Merkmalen der eingangs genannten Art zur Verfügung zu stellen, der bei einfacher Bauweise und werkzeugloser Zerlegbarkeit eine sichere Verriegelung über einen drehbaren Verschlusskopf gewährleistet.The object of the present invention is to provide a breech, in particular a straight-action breech, for a firearm with the features of the type mentioned at the outset, which, with a simple construction and tool-free dismantling, ensures secure locking via a rotating breech head.

Die Lösung der Aufgabe liefert ein Verschluss für Schusswaffen der eingangs genannten Gattung mit den Merkmalen des Anspruchs 1.The solution to the problem is provided by a breech for firearms of the aforementioned type with the features of claim 1.

Erfindungsgemäß ist vorgesehen, dass das Steuerstück über ein Zwischenstück mit dem Kammerhebel verbunden ist, welches von der Kammer aus radial nach außen hin ragt, dass der Verschlusskopf um seine Achse drehbar in der Kammer gelagert ist und der Verschlusskopf durch axiales Verschieben des Steuerstücks gedreht wird.According to the invention, it is provided that the control piece is connected to the chamber lever via an intermediate piece, which projects radially outward from the chamber, that the closure head is rotatably mounted in the chamber about its axis and that the closure head is rotated by axially displacing the control piece.

Bei der aus der DE 196 08 872 C1 bekannten Verschlusseinrichtung für Schusswaffen ist der Verschlusskopf nicht drehbar. Zwar gibt es im Stand der Technik auch Geradzugverschlüsse für Schusswaffen, bei denen der Verschlusskopf in einer Kammer drehbar um die eigene Achse gelagert ist, wie beispielsweise in der oben genannten EP 0 784 194 A2 beschrieben. Jedoch wird bei diesen bekannten Verschlusseinrichtungen aus verschiedenen Gründen konstruktiv bedingt nur ein vergleichsweise geringer Drehwinkel erreicht.With the from the DE 196 08 872 C1 known locking device for firearms, the breech head is not rotatable. In the prior art there are also straight-line breeches for firearms, in which the breech head is rotatably mounted in a chamber about its own axis, such as the one mentioned above EP 0 784 194 A2 described. However, for various reasons, in these known closure devices only a comparatively small angle of rotation is achieved for structural reasons.

Bei der erfindungsgemäßen Lösung wird hingegen das Steuerstück über ein Zwischenstück mit dem Kammerhebel verbunden. Da die Achse, um die der Kammerhebel schwenkt, außermittig (bezogen auf die Längsachse der Kammer) angeordnet ist und das Zwischenstück, an dem der Kammerhebel angreift, an der der Schwenkachse des Kammerhebels gegenüberliegenden Seite der Waffe angebracht werden kann und dabei noch radial außen liegt, befindet sich auch der Angriffspunkt des Kammerhebels an dem Zwischenstück in einem vergleichsweise großen Abstand zu der Schwenkachse des Kammerhebels, was wiederum zur Folge hat, dass bei der Schwenkbewegung des Kammerhebels ein großer Längshub des Zwischenstücks und damit des Steuerstücks erreicht wird. Dieser vergleichsweise große Längshub des Steuerstücks wird dann in eine Drehbewegung des Verschlusskopfs mit entsprechend großem Drehwinkel umgesetzt, wodurch eine sichere Verriegelung des Verschlusskopfs erreicht wird.In the solution according to the invention, however, the control piece is connected to the chamber lever via an intermediate piece. Since the axis around which the chamber lever swings, is arranged eccentrically (based on the longitudinal axis of the chamber) and the intermediate piece, on which the chamber lever engages, on which side of the weapon opposite the pivot axis of the chamber lever can be attached and is still located radially on the outside, is also the point of application of the chamber lever on the Intermediate piece at a comparatively large distance from the pivot axis of the chamber lever, which in turn has the result that a large longitudinal stroke of the intermediate piece and thus of the control piece is achieved during the pivoting movement of the chamber lever. This comparatively large longitudinal stroke of the control piece is then converted into a rotary movement of the closure head with a correspondingly large angle of rotation, as a result of which a secure locking of the closure head is achieved.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist das Zwischenstück in wenigstens einer Nut oder Ausnehmung in der Wand der Hülse in Längsrichtung verschieblich geführt. Zum einen ergibt sich dadurch eine zusätzliche Führung für das Zwischenstück in der Hülse und das Zwischenstück kann soweit radial außen angeordnet werden, dass es sich in radialer Richtung nicht nur über die Kammer hinaus, sondern zumindest teilweise auch über die Hülse hinaus nach außen erstreckt.According to a preferred development of the invention, the intermediate piece is displaceably guided in the longitudinal direction in at least one groove or recess in the wall of the sleeve. On the one hand, this results in an additional guide for the intermediate piece in the sleeve, and the intermediate piece can be arranged radially on the outside to such an extent that it not only extends beyond the chamber in the radial direction, but also at least partially beyond the sleeve.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist das Zwischenstück außerdem in einem Langloch der Kammer in Längsrichtung verschieblich geführt.According to a preferred development of the invention, the intermediate piece is also guided in a longitudinally displaceable manner in an elongated hole in the chamber.

Gemäß der Erfindung ist eine gelenkige Verbindung des Kammerhebels mit dem Zwischenstück über ein Achselement vorgesehen, dessen Achse parallel zur Achse verläuft, um die der Kammerhebel schwenkbar gelagert ist, wobei das Achselement in der Draufsicht gesehen radial außerhalb der Flucht der Kammer angeordnet ist. Das Achselement weist somit einen vergleichsweise großen Abstand (in Querrichtung der Waffe) zur Schwenkachse des Kammerhebels auf, wodurch sich bei Betätigung des Kammerhebels ein langer Schwenkweg und somit eine große Strecke ergibt, die das Zwischenstück beim Zurückziehen des Kammerhebels zurücklegt. Dies führt wiederum zu einem großen Längshub des Steuerstücks und damit zu einem großen Drehwinkel des Verschlusskopfs.According to the invention, an articulated connection of the chamber lever to the intermediate piece is provided via an axle element, the axis of which runs parallel to the axis about which the chamber lever is pivotably mounted, the axle element being arranged radially outside the flight of the chamber when viewed in plan view. The axis element is thus at a comparatively large distance (in the transverse direction of the weapon) from the pivot axis of the chamber lever, which results in a long pivot path and thus a large distance when the chamber lever is actuated, which the intermediate piece travels when the chamber lever is withdrawn. This in turn leads to a large longitudinal stroke of the control piece and thus to a large angle of rotation of the closure head.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist seitlich radial außen in der Kammer etwa in deren hinteren Endbereich ein Rastbolzen angeordnet, welcher mit einer federbelasteten Wippe zusammenwirkt, wobei bei Zurückziehen des Kammerhebels die Wippe und der Rastbolzen von der Hülse freigegeben werden und der Rastbolzen dann in eine entsprechende Ausnehmung des Steuerstücks eingreift, womit dessen Axialbewegung blockiert wird.According to a preferred development of the invention, a locking bolt is arranged laterally radially outside in the chamber, approximately in its rear end region, which interacts with a spring-loaded rocker, the rocker and the locking bolts being released from the sleeve when the chamber lever is withdrawn, and the locking bolt then being in a appropriate Recess of the control piece engages, whereby its axial movement is blocked.

Gemäß einer bevorzugten Weiterbildung der Erfindung befindet sich ein etwa radial nach außen ragender Steuerbolzen im vorderen Bereich an dem Steuerstück, welcher in eine Steuernut in einem Teilabschnitt des Verschlusskopfes eingreift, von dem der vordere Bereich des Steuerstücks konzentrisch aufgenommen wird.According to a preferred development of the invention, there is an approximately radially outwardly projecting control pin in the front area on the control piece, which engages in a control groove in a partial section of the closure head, from which the front area of the control piece is concentrically received.

Gemäß einer bevorzugten Weiterbildung der Erfindung weist das Zwischenstück zur Verbindung mit dem Steuerstück einen Fortsatz oder eine Nase auf, mit dem(r) es radial einwärts ragend in eine radiale Bohrung in dem Steuerstück eingreift.According to a preferred development of the invention, the intermediate piece for connection to the control piece has an extension or a lug with which it engages in a radial bore in the control piece, projecting radially inward.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist der Achsbolzen, der als Schwenkachse für den Kammerhebel dient, in seiner axialen Richtung eindrückbar gelagert, wobei durch Eindrücken der Kammerhebel freigegeben wird und die Schlagbolzen-Baugruppe axial nach hinten entnehmbar ist.According to a preferred development of the invention, the axle pin, which serves as a pivot axis for the chamber lever, is mounted so that it can be pressed in in its axial direction, the chamber lever being released by pressing in and the firing pin assembly can be removed axially to the rear.

Gemäß einer bevorzugten Weiterbildung der Erfindung greift das Achselement, über das der Kammerhebel schwenkbar mit dem Zwischenstück verbunden ist, in eine Quernut an der Unterseite des Zwischenstücks ein.According to a preferred development of the invention, the axle element, via which the chamber lever is pivotally connected to the intermediate piece, engages in a transverse groove on the underside of the intermediate piece.

Gemäß einer bevorzugten Weiterbildung der Erfindung weist das Zwischenstück oberseitig eine Nut auf, über die es bei Betätigung des Kammerhebels zur Ausführung einer Schwenkbewegung des Kammerhebels gegenüber einem verbreiterten Hinterteil der Kammer verschiebbar geführt ist.According to a preferred development of the invention, the intermediate piece has a groove on the top, via which it is displaceably guided when the chamber lever is actuated in order to execute a pivoting movement of the chamber lever in relation to a widened rear part of the chamber.

Weitere Vorteile der Erfindung ergeben sich aus der nachfolgenden Detailbeschreibung.The features mentioned in the subclaims relate to preferred developments of the task solution according to the invention.

Zunächst wird auf die Figuren 1 und 2 Bezug genommen und anhand dieser wird der grundsätzliche Aufbau des erfindungsgemäßen Verschlusses erläutert. Beide Darstellungen zeigen den Verschluss jeweils in der verriegelten und abgeschlagenen Stellung. Es handelt sich um einen in einer im Wesentlichen rohrförmigen zylindrischen Hülse 1 angeordneten Geradzugverschluss, dessen vorderer Verschlusskopf 2 drehbar, aber nicht verschiebbar in einer ebenfalls in der Grundform etwa zylindrischen Kammer 3 gelagert ist, wobei die Kammer 3 wiederum koaxial in der zylindrischen Hülse aufgenommen ist. Wie auch in der stirnseitigen Ansicht gemäß den Figuren 7 a und 7 b erkennbar ist, weist der Verschlusskopf 2 radial außen als Warzen ausgebildete Verriegelungselemente 7 auf, die in entsprechende Verriegelungselemente 8 des Laufes oder der Hülse 1 ein- und ausgekuppelt werden können. An seiner Hinterseite weist der Verschlusskopf 2 wenigstens eine Steuernut 11 auf (siehe auch Figuren 6a, 6b), die eine konstante oder eine progressive Steigung hat.First, the Figures 1 and 2 Reference and the basic structure of the closure according to the invention is explained based on this. Both representations show the lock in the locked and unlocked position. It is a straight-line closure arranged in an essentially tubular cylindrical sleeve 1, the front closure head 2 of which is rotatably but not displaceably mounted in a chamber 3, which is also roughly cylindrical in basic form, the chamber 3 in turn being accommodated coaxially in the cylindrical sleeve , As in the front view according to the Figures 7 a and 7 b can be seen, the closure head 2 has locking elements 7 which are designed radially on the outside as warts and can be coupled into and out of corresponding locking elements 8 of the barrel or the sleeve 1. On its rear side, the closure head 2 has at least one control groove 11 (see also Figures 6a, 6b ) that has a constant or a progressive slope.

Der Verschlusskopf 2 ist durch den Absatz 10 in seiner Axialbewegung gegenüber der Kammer 3 fixiert. Es ist ein Steuerstück 4 vorgesehen, welches im Verschlusskopf 2 und in der Hülse 3 axial verschiebbar gelagert ist. Das Steuerstück 4 weist in seinem vorderen Endbereich einen sich radial nach außen erstreckenden Steuerbolzen 12 auf, dessen Oberfläche im Kontakt mit der Steuernut 11 des Verschlusskopfes 2 ist (siehe auch Figuren 6 a und 6 b).The locking head 2 is fixed in its axial movement relative to the chamber 3 by the shoulder 10. A control piece 4 is provided, which is mounted axially displaceably in the closure head 2 and in the sleeve 3. The control piece 4 has in its front end region a radially outwardly extending control pin 12, the surface of which is in contact with the control groove 11 of the closure head 2 (see also Figures 6 a and 6 b).

In den Figuren 2 und 4 ist der Kammerhebel 6 erkennbar, der schwenkbeweglich und formschlüssig um einen Achsbolzen 16 schwenkbar am hinteren Ende der Kammer 3 gelagert ist (siehe auch Figuren 11a, b und 12). Dies ermöglicht eine schnelle und werkzeuglose Zerlegbarkeit. Durch Schwenken des Kammerhebels 6 um den Achsbolzen 16 wird das Steuerstück 4 über ein mit diesem verbundenes Zwischenstück 17 in Axialrichtung bewegt. Die Bewegung des Zwischenstücks 17 kann man recht gut durch Vergleich der Figuren 8 a und 8 b einerseits sowie auch der Figuren 11 a und 11 b erkennen.
Das Zwischenstück 17 ist in der Kammer 3 axial verschiebbar gelagert und durch die Nase 18 mit dem Steuerstück 4 verbunden (siehe Figuren 2 und 4). Am hinteren Ende ist das Zwischenstück 17 durch die Quernut 19 und das Achselement 20 mit dem Kammerhebel 6 verbunden (siehe Figur 16).In the Figures 2 and 4 can be seen the chamber lever 6, which is pivotally movably and positively pivoted about an axle pin 16 at the rear end of the chamber 3 (see also Figures 11a, b and 12 ). This enables quick and tool-free dismantling. By pivoting the chamber lever 6 around the axle pin 16, the control piece 4 is moved in the axial direction via an intermediate piece 17 connected to it. The movement of the intermediate piece 17 can be compared quite well Figures 8 a and 8 b on the one hand and also the Figures 11 recognize a and 11 b.
The intermediate piece 17 is axially displaceably mounted in the chamber 3 and connected to the control piece 4 by the nose 18 (see Figures 2 and 4 ). At the rear end, the intermediate piece 17 is connected to the chamber lever 6 by the transverse groove 19 and the axle element 20 (see Figure 16 ).

Am hinteren Ende der Kammer 3 ist auf der dem Zwischenstück 17 am Umfang gegenüber liegenden Seite der Kammer 3 ein Rastbolzen 21 mit einer unter Federdruck stehenden Wippe 22 angeordnet (siehe Figur 2). Dieser Rastbolzen 21 rastet in eine Ausnehmung 23 (siehe Figur 2) ein, wenn man beim Repetieren der Waffe die Kammer 3 aus der Hülse 1 bewegt (siehe Figur 4).At the rear end of the chamber 3, on the side of the chamber 3 opposite the intermediate piece 17 on the circumference, a locking pin 21 with a spring-loaded rocker 22 is arranged (see Figure 2 ). This locking pin 21 snaps into a recess 23 (see Figure 2 ) when moving chamber 3 out of sleeve 1 while repeating the weapon (see Figure 4 ).

Die Funktionsweise des erfindungsgemäßen Verschlusses wird nachfolgend erläutert. Bei der Bewegung des Verschlusses in die in den Figuren 1 und 2 gezeigte verriegelte und abgeschlagene Stellung wird der Kammerhebel 6 nach vorn bewegt und geschwenkt, wodurch auch das Zwischenstück 17 und das Steuerstück 4 in eine vordere Position bewegt werden. Zum Öffnen des Verschlusses wird der Kammerhebel 6 zurückgezogen, wodurch auch das Zwischenstück 17 und das mit diesem verbundene Steuerstück 4 zurückgezogen werden in die in den Figuren 3 und 4 dargestellte Position. Während der Rückwärtsbewegung wird über die in den Verschlusskopf 2 eingebrachte Steuernut 11 und den Steuerbolzen 12 der Verschlusskopf 2 um die eigene Achse 13 gedreht und dadurch entriegelt. Hier wird auch auf die Figuren 6 a und 6 b verwiesen, die das Steuerstück 4 in der vorderen und in der herausgezogenen hinteren Position zeigen. Man kann hier gut erkennen, wie sich der Steuerbolzen 12 in der Steuernut 11 bewegt. Da der Verschlusskopf 2 in axialer Richtung festgehalten wird, dreht er sich beim Zurückziehen des Steuerstücks um seine Achse. Die beiden Drehpositionen des Verschlusskopfs sind auch in den Figuren 7 a und 7 b dargestellt, die den Verschlusskopf 2 von der Stirnseite her zeigen.The functioning of the closure according to the invention is explained below. When moving the fastener into the Figures 1 and 2 Locked and knocked-off position shown, the chamber lever 6 is moved forward and pivoted, whereby the intermediate piece 17 and the control piece 4 are moved to a front position. To open the closure, the chamber lever 6 is pulled back, as a result of which the intermediate piece 17 and the control piece 4 connected to it are pulled back into the in the Figures 3 and 4 position shown. During the backward movement, the locking head 2 is rotated about its own axis 13 via the control groove 11 and the control bolt 12 introduced into the locking head 2 and thereby unlocked. Here is also on the Figures 6 Reference a and 6 b, which show the control piece 4 in the front and in the extended rear position. One can clearly see here how the control pin 12 moves in the control groove 11. Since the closure head 2 is held in the axial direction, it rotates about its axis when the control piece is withdrawn. The two rotational positions of the breech head are also in the Figures 7 a and 7 b shown, which show the closure head 2 from the front side.

Beim weiteren Zurückziehen des Kammerhebels 6 (siehe Figur 5) wird die Wippe 22 und somit der Rastbolzen 21 von der Hülse 1 freigegeben. Dies bedeutet, dass der Rastbolzen 21 in die entsprechende Ausnehmung des Steuerstücks 4 eingreift und dessen Axialbewegung blockiert. Der Verschlusskopf 2 kann nun mit der Kammer 3 und dem Steuerstück 4 in axialer Richtung nach hinten hin aus der Hülse herausgezogen werden. Es findet dann keine Drehbewegung des Verschlusskopfs 2 und keine Axialbewegung des Steuerstücks 4 innerhalb der Kammer 3 mehr statt.When the chamber lever 6 is pulled back further (see Figure 5 ) the rocker 22 and thus the locking pin 21 is released from the sleeve 1. This means that the locking pin 21 engages in the corresponding recess of the control piece 4 and its axial movement blocked. The closure head 2 can now be pulled out of the sleeve with the chamber 3 and the control piece 4 in the axial direction towards the rear. There is then no more rotary movement of the closure head 2 and no more axial movement of the control piece 4 within the chamber 3.

Wenn Kammerhebel 6 und Verschlusskopf 2 in der entriegelten Stellung fixiert sind, kann der Verschluss ungehindert gleiten und dadurch wird der Repetiervorgang ausgeführt.When chamber lever 6 and locking head 2 are fixed in the unlocked position, the lock can slide freely and the repeating process is carried out.

Beim Schließen des Verschlusses (Figur 4) wird der Kammerhebel 6 und somit der Verschlusskopf 2 erst dann zur Drehbewegung freigegeben, wenn die Wippe 22 über die Kante der Hülse 1 weiter nach vorne geschoben wird (siehe auch Figur 5).When closing the lock ( Figure 4 ) The chamber lever 6 and thus the locking head 2 are only released for rotary motion when the rocker 22 is pushed further forward over the edge of the sleeve 1 (see also Figure 5 ).

Das Steuerstück 4 wird durch die Schließfeder 9 nach vorn gedrückt, was den Schließvorgang erleichtert und den Verschlusskopf 2 in der verriegelten Stellung hält (siehe Figur 2).The control piece 4 is pressed forward by the closing spring 9, which facilitates the closing process and keeps the closing head 2 in the locked position (see Figure 2 ).

In den Figuren 6 a und 6 b ist das Steuerstück 4 ohne die Kammer 3 dargestellt, in der es axial verschieblich gelagert ist. Man erkennt hier recht gut die Steuernut 11 im Verschlusskopf 2 und den Steuerbolzen 12, welcher in dieser Steuernut 11 geführt ist. Wird nun aus der verriegelten Stellung gemäß Figur 6 a das Steuerstück 4 über das hier nicht abgebildete Zwischenstück 17 nach hinten bewegt, dann führt dies zu der Drehbewegung des Verschlusskopfes in die in Figur 6b dargestellte Stellung. Durch Vergleich dieser beiden Ansichten wird der vergleichsweise große Längshub des Steuerstücks 4 erkennbar. In diesen beiden Zeichnungen sieht man außerdem die radiale Bohrung 25 des Steuerstücks 4, in die die Nase 18 (siehe Figur 2) des Zwischenstücks eingreift, wodurch die Verbindung zwischen Zwischenstück 17 und Steuerstück 4 hergestellt wird.In the Figures 6 a and 6 b, the control piece 4 is shown without the chamber 3, in which it is axially displaceably mounted. The control groove 11 in the closure head 2 and the control bolt 12, which is guided in this control groove 11, can be seen quite well here. Will now from the locked position Figure 6 a the control piece 4 moves back over the intermediate piece 17, not shown here, then this leads to the rotary movement of the closure head in the in Figure 6b position shown. By comparing these two views, the comparatively large longitudinal stroke of the control piece 4 can be seen. In these two drawings you can also see the radial bore 25 of the control piece 4, into which the nose 18 (see Figure 2 ) engages the intermediate piece, whereby the connection between intermediate piece 17 and control piece 4 is established.

Die stirnseitigen Ansichten gemäß den Figuren 7 a und 7 b lassen die Größe des Drehwinkels bei dem zuvor beschriebenen Vorgang der Verriegelung des Verschlusskopfes 2 erkennen und man sieht, dass es sich um einen Drehwinkel von ca. 60° handelt, was erheblich mehr ist, als bei aus dem Stand der Technik bekannten Vorrichtungen. Weiterhin sieht man in den Figuren 7 a und 7 b die Umrissform des Verschlusskopfs 2 in seinem Endbereich, die mit Nasen, Vorsprüngen oder dergleichen so geformt ist, dass in der Stellung gemäß Figuren 7 a/6 a die Verriegelung gegeben ist, während nach der Drehung in die Position gemäß Figur 7b der Verschlusskopf 2 formschlüssig in eine entsprechend geformte Innenkontur in der Hülse 1 passt und daher in der Hülse zurückgleiten kann. Diesbezüglich wird auch auf die jeweiligen Verriegelungselemente 7, 8 von Verschlusskopf 2 und Hülse 1 verwiesen, die in der Darstellung gemäß den Figuren 3 und 4 nach der Entriegelung freiliegen.The end views according to the Figures 7 a and 7 b show the size of the angle of rotation in the previously described process of locking the closure head 2 and it can be seen that it is a rotation angle of approximately 60 °, which is considerably more than in known from the prior art devices. Furthermore you can see in the Figures 7 a and 7 b the outline shape of the closure head 2 in its end region, which is shaped with lugs, projections or the like so that in the position according to Figures 7 a / 6 a the lock is given while after rotating into position according to Figure 7b the closure head 2 fits positively into a correspondingly shaped inner contour in the sleeve 1 and can therefore slide back in the sleeve. In this regard, reference is also made to the respective locking elements 7, 8 of the closure head 2 and sleeve 1, which in the illustration according to the Figures 3 and 4 exposed after unlocking.

Die Figuren 8 a und 8 b zeigen jeweils eine Seitenansicht im hinteren Bereich der Waffe, wobei man die Verbindung von Zwischenstück 17 und Kammerhebel 6 erkennt, sowie das Langloch 24 in der Kammer, in dem das Zwischenstück 17 in der ersten Phase der Bewegung des Kammerhebels 6 nach hinten, bis zur Entriegelung des Verschlusskopfes 2 geführt ist. In der zweiten Bewegungsphase, nachdem der Rastbolzen 21 freigegeben wurde, bewegt sich der Verschluss mit der Kammer 3 aus der Hülse 1 heraus axial nach hinten und das Zwischenstück 17 ist dann gegenüber der Kammer 3 arretiert.The Figures 8 a and 8 b each show a side view in the rear area of the weapon, whereby the connection between the intermediate piece 17 and chamber lever 6 can be seen, as well as the elongated hole 24 in the chamber, in which the intermediate piece 17 in the first phase of the movement of the chamber lever 6 backwards , until the locking head 2 is unlocked. In the second movement phase, after the locking bolt 21 has been released, the closure with the chamber 3 moves axially out of the sleeve 1 and the intermediate piece 17 is then locked in relation to the chamber 3.

Die Figuren 9 a und 9 b zeigen die jeweiligen Seitenansichten der Figuren 8 a und 8 b, wobei man in Figur 9 von oben her auf die Waffe schaut. Man erkennt hier, dass das Zwischenstück 17 oberseitig eine Nut 26 aufweist, über die es bei Betätigung des Kammerhebels 6 zur Ausführung dessen Schwenkbewegung gegenüber dem Hinterteil der Kammer verschiebbar geführt ist. Weil das Zwischenstück 17 so in zwei zueinander rechtwinkligen Bereichen geführt ist (einmal an der Hülse 1 und einmal an dem breiteren Hinterteil der Kammer 3), ist es bei seiner Bewegung an der Waffe gefangen. Das genannte verbreiterte Hinterteil der Kammer ist so ausgeführt, dass es bei in die Hülse 1 eingeschobener Kammer 3 bündig am hinteren Ende der Hülse 1 anliegt (siehe Figuren 1 und 2).The Figures 9 a and 9 b show the respective side views of the Figures 8 a and 8 b, where in Figure 9 looks at the gun from above. It can be seen here that the intermediate piece 17 has a groove 26 on the top side, via which it is displaceably guided when the chamber lever 6 is actuated in order to execute its pivoting movement relative to the rear part of the chamber. Because the intermediate piece 17 is guided in two mutually perpendicular areas (once on the sleeve 1 and once on the wider rear part of the chamber 3), it is caught on the weapon during its movement. The widened rear part of the chamber is designed such that it lies flush against the rear end of the sleeve 1 when the chamber 3 is pushed into the sleeve 1 (see Figures 1 and 2 ).

Die Figuren 11 a und 11 b zeigen wiederum in der verriegelten und in der entriegelten Stellung den Bereich mit dem Kammerhebel 6 und dem Zwischenstück 17, wobei man hier den Kammerhebel 6 quasi von unten her sieht. Hier ist zum einen der Achsbolzen 16 erkennbar, um den der Kammerhebel 6 schwenkt und man sieht den Stift 20, der den Schwenkpunkt der gelenkigen Verbindung zwischen dem Kammerhebel 6 und dem Zwischenstück 17 definiert. Figur 12 zeigt einen Schnitt durch den Kammerhebel 6, in dem man den Achsbolzen 16 erkennt und die Nut 26 an der Oberseite des Zwischenstücks 17.The Figures 11 a and 11 b again show in the locked and in the unlocked position the area with the chamber lever 6 and the intermediate piece 17, the chamber lever 6 being seen here from below, so to speak. Here, on the one hand, the axle pin 16 can be seen, around which the chamber lever 6 pivots and one sees the pin 20, which defines the pivot point of the articulated connection between the chamber lever 6 and the intermediate piece 17. Figure 12 shows a section through the chamber lever 6, in which one recognizes the axle pin 16 and the groove 26 on the top of the intermediate piece 17th

Figur 13 zeigt den Kammerhebel 6 mit dem Zwischenstück 17 und in der Schnittansicht gemäß Figur 14 sieht man den Kammerhebel 6 mit dem Achsbolzen 16 für dessen Gelenkachse. Weiterhin ist in Figur 14 die Nase 18 erkennbar, über die das Zwischenstück 17 mit dem Steuerstück 4 verbunden wird. Figur 15 zeigt im Prinzip die Seitenansicht von Figur 13, so dass man den Kammerhebel 6 von unten her sieht. Bei der Schnittansicht gemäß Figur 16 verläuft die Schnittlinie durch den Achsbolzen 16 und durch den Stift 20, so dass man hier erkennt, wie der Kammerhebel 6 mit dem Zwischenstück 17 gelenkig über den Stift 20 verbunden ist. Figure 13 shows the chamber lever 6 with the intermediate piece 17 and in the sectional view according to Figure 14 you can see the chamber lever 6 with the axle pin 16 for its hinge axis. Furthermore, in Figure 14 the nose 18 can be seen, via which the intermediate piece 17 is connected to the control piece 4. Figure 15 basically shows the side view of Figure 13 , so that you can see the chamber lever 6 from below. In the sectional view according to Figure 16 The section line runs through the axle pin 16 and through the pin 20, so that one can see here how the chamber lever 6 is connected in an articulated manner to the intermediate piece 17 via the pin 20.
