Description

Die Erfindung betrifft eine Laufklemmung einer Schusswaffe mit einem Lauf und einer den Lauf tragenden Systemhülse.The invention relates to a barrel clamping of a firearm with a barrel and a system sleeve carrying the barrel.

Der Lauf einer Waffe muss mit dem System beziehungsweise mit der Systemhülse verbunden werden. Dies kann bekanntermaßen durch auf das Laufende wirkende, an der Systemhülse gelagerte Schrauben erfolgen. Auch ein Einpressen oder ein Einkleben oder auch Verstiften des Laufendes in der Systemhülse ist bekannt. Ein Wechsel des Laufs bzw. dessen Demontage ist dabei nicht mehr möglich.The barrel of a weapon must be connected to the system or the system sleeve. As is known, this can be done by screws acting on the running end mounted on the system sleeve. Pressing in or gluing or also pinning the running end in the system sleeve is also known. It is no longer possible to change the barrel or dismantle it.

Aus der DE-OS 2456973 ist eine Feuerwaffe mit rücklaufendem Lauf und einer beim Abfeuern eines Schusses zum Abbremsen der Laufrücklaufbewegung in Bezug auf das Schlossgehäuse dienenden Rückstoßbremse bekannt, wobei eine zwischen Lauf und Rückstoßbremse angeordnete, von Hand betätigbare mechanische Kopplungsvorrichtung vorgesehen ist, wobei die ganze Waffe in der Weise ausgebildet ist, dass der Lauf der Waffe bei außer Betrieb gesetzter Rückstoßbremse von Hand in das Schlossgehäuse einschiebbar ist.From the DE-OS 2456973 is known a firearm with a recoil barrel and a recoil brake which is used when firing a shot to brake the recoil motion in relation to the lock housing, wherein a manually operable mechanical coupling device is provided between the barrel and recoil brake, the whole weapon being designed in this way that the barrel of the weapon can be pushed into the lock housing by hand when the recoil brake is deactivated.

Aufgabe der Erfindung ist es eine verbesserte Laufklemmung zur Verfügung zu stellen, bei der eine einfache und sichere Halterung als auch ein Lösen des Laufs in einer Systemhülse ermöglicht ist.The object of the invention is to provide an improved barrel clamp, in which a simple and secure mounting as well as a release of the barrel is made possible in a system sleeve.

Diese Aufgabe wird durch eine Laufklemmung einer Schusswaffe mit einem Lauf und einer den Lauf tragenden Systemhülse nach den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a barrel clamping of a firearm with a barrel and a system sleeve carrying the barrel according to the features of claim 1.

Erfindungsgemäß ist vorgesehen, dass die Systemhülse eine Laufaufnahme aufweist, in die das Laufende des Laufs gesteckt wird, wobei zur Klemmung des Laufendes in der Laufaufnahme wenigstens ein in Querschnitt sichelförmiges Klemmstück vorhanden ist, welches in einer Klemm-Nut an der Systemhülse liegt und gegen das Laufende gedrückt werden kann.According to the invention it is provided that the system sleeve has a barrel receptacle into which the running end of the barrel is inserted, with at least one crescent-shaped clamping piece being present in the barrel receptacle for clamping the barrel end, which is located in a clamping groove on the system sleeve and against it Current can be pressed.

Hierdurch ist auf besonders effektive Weise eine sehr vorteilhafte Drei-Punkt-Klemmung des Laufendes zum einen gegen die Laufaufnahme und zum anderen gegen die äußeren Enden des Klemmstücks ermöglicht. Dabei bleibt der Lauf jederzeit durch Lösen der Klemmung durch wegbewegen des Klemmstücks vom Laufende auswechselbar. Durch die Zylinderabschnitts-förmige Ausgestaltung des Klemmstücks ist dabei eine axiale als auch eine radiale Verklemmung ermöglicht. Klemmschrauben haben hier bisher nur Punktverbindungen geschaffen.This enables in a particularly effective manner a very advantageous three-point clamping of the barrel end on the one hand against the barrel holder and on the other hand against the outer ends of the clamping piece. The barrel remains interchangeable at any time by releasing the clamp by moving the clamping piece away from the barrel end. The cylindrical section-shaped design of the clamping piece enables axial as well as radial clamping. Up to now, clamping screws have only created point connections.

Bevorzugterweise ist der Innen-Radius des Klemmstücks kleiner als der Außenradius des Laufendes. Hierdurch ist eine Verformung des Klemmstücks gegen das Laufende hin möglich, wodurch die Haltekraft vorwählbar wird.The inner radius of the clamping piece is preferably smaller than the outer radius of the running end. This allows the clamping piece to be deformed towards the running end, as a result of which the holding force can be preselected.

Dem folgend ist nach einer Ausgestaltung der Erfindung vorgesehen, dass das Klemmstück vermittels einer in der Systemhülse radial zum zylinderförmigen Laufende gelagerten Spann-Schraube gegen das Laufende unter elastischer Verformung gedrückt ist.According to one embodiment of the invention, it is provided that the clamping piece is pressed against the running end with elastic deformation by means of a tensioning screw mounted radially to the cylindrical running end in the system sleeve.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass wenigstens eines der Klemmstücke in einer Klemmstück-Aufnahme-Nut am Laufende gedrückt ist.An advantageous embodiment of the invention provides that at least one of the clamping pieces is pressed in a clamping piece receiving groove at the running end.

Eine Weiterbildung der Erfindung sieht vor, dass die Klemmstück-Aufnahme-Nut zum Ende des Laufs hin Konus-förmig ausgestaltet ist. Hierdurch kann das Laufende sicher in die Laufaufnahme gezogen werden, wobei die Enden des Klemmstücks auf die Schrägfläche des Konus wirken können.A further development of the invention provides that the clamping piece receiving groove is designed in the shape of a cone towards the end of the barrel. As a result, the running end can be pulled securely into the barrel receptacle, the ends of the clamping piece being able to act on the inclined surface of the cone.

Eine Verdreh-Sicherung des Laufendes in der Laufaufnahme ist von Vorteil ausgestaltet, wobei ein am Laufende vorhandener Vorsprung in eine entsprechende Ausnehmung an der Systemhülse im eingesteckten Zustand des Laufendes in der Laufaufnahme eingreift.An anti-rotation device of the running end in the running receptacle is advantageously designed, wherein a projection present at the running end engages in a corresponding recess in the system sleeve in the inserted state of the running end in the running receptacle.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen oder deren mögliche Unterkombinationen.Further advantageous embodiments result from the further subclaims or their possible subcombinations.

Die in den Figuren gleichen Bezugsziffern bezeichnen gleiche oder gleich wirkende Elemente.The same reference numerals in the figures denote the same or equivalent elements.

In Fig. 1 ist eine beispielhafte Laufklemmung einer Schusswaffe mit einem Lauf 1 und einer den Lauf 1 tragenden Systemhülse 3 in Einzelteilen gezeigt.In Fig. 1 An exemplary barrel clamping of a firearm with a barrel 1 and a system sleeve 3 carrying the barrel 1 is shown in individual parts.

Die Systemhülse 3 weist eine Laufaufnahme 4 auf, in die das Laufende 2 des Laufs 1 gesteckt werden kann. Dabei erfolgt die Klemmung des Laufendes 2 in der Laufaufnahme 4 mit im Beispiel zwei im Querschnitt sichelförmigen Klemmstücken 5.The system sleeve 3 has a barrel holder 4 into which the barrel end 2 of barrel 1 can be inserted. The running end 2 is clamped in the running receptacle 4 with two clamping pieces 5 which are crescent-shaped in cross section in the example.

Das Klemmstück 5 liegt jeweils in einer Klemm-Nut 6 an der Systemhülse 3 und wird im montierten Zustand gegen das Laufende 2 gedrückt.The clamping piece 5 is located in a clamping groove 6 on the system sleeve 3 and is pressed against the running end 2 in the assembled state.

In Fig. 2 ist das Klemmstück in einer Seitenansicht im Detail gezeigt. Der Innenradius 51 des Klemmstücks 5 ist kleiner als der Außenradius 21 des Laufendes 2 - siehe hierzu auch Fig. 10.In Fig. 2 the clamping piece is shown in detail in a side view. The inner radius 51 of the clamping piece 5 is smaller than the outer radius 21 of the running end 2 - see also here Fig. 10 .

Fig. 3 zeigt eine schematische Schnitt-Darstellung des Klemmstücks aus Fig. 2 in Blickrichtung A. Fig. 3 shows a schematic sectional view of the clamping piece from Fig. 2 looking in direction A.

Eine beispielhafte Spann-Schraube 7 ist in einer schematischen Seitenansicht in Fig. 4 gezeigt. Der Spann-Schraubenkopf 71 ist dabei zur Zusammenwirkung mit einer entsprechenden Spann-Schraubenkopf-Aufnahme 53 an dem Klemmstück 5, siehe hierzu beispielsweise Fig. 3 und Fig. 10 bis 12, ausgebildet.An exemplary clamping screw 7 is shown in a schematic side view in FIG Fig. 4 shown. The clamping screw head 71 is to interact with a corresponding one Clamping screw head receptacle 53 on the clamping piece 5, see for example Fig. 3 and 10 to 12 , educated.

Fig. 5 zeigt eine schematische Schnitt-Darstellung durch eine Systemhülse 3 mit Laufaufnahme 4. Die Spann-Schraube 7 ist in einem in einer Spann-Schrauben-Aufnahme 61 ausgebildeten Gewinde geführt. Oberhalb der Spann-Schrauben-Aufnahmen 61 sind die Klemm-Nuten 6 ausgebildet, in denen die Klemmstücke 5 liegen, siehe hierzu auch Fig. 9 und 10 bis 12. Fig. 5 shows a schematic sectional view through a system sleeve 3 with barrel holder 4. The clamping screw 7 is guided in a thread formed in a clamping screw holder 61. Above the clamping screw receptacles 61, the clamping grooves 6 are formed, in which the clamping pieces 5 lie, see also here Fig. 9 and 10 to 12 .

Die Fig. 6 bis 8 zeigen das Laufende 2 in verschiedenen Ansichten.The 6 to 8 show the current 2 in different views.

Fig. 9 zeigt eine schematische Schnitt-Darstellung durch eine voll montierte Laufklemmung mit einem Laufende 2 geklemmt in der Laufaufnahme 4 der Systemhülse 3. Die Klemmstücke 5 sind vermittels jeweils einer in der Systemhülse 3 radial zum zylinderförmigen Laufende 2 gelagerten Spann-Schraube 7 gegen das Laufende 2 unter elastischer Verformung des Klemmstücks 5 gedrückt. Fig. 9 shows a schematic sectional view through a fully assembled barrel clamp with a barrel end 2 clamped in the barrel receptacle 4 of the system sleeve 3. The clamping pieces 5 are each by means of a clamping screw 7, which is mounted radially to the cylindrical barrel end 2 against the barrel end 2 in the system sleeve 3 elastic deformation of the clamping piece 5 pressed.

Eines der Klemmstücke 5 ist in einer Klemmstück-Aufnahme-Nut 22 am Laufende 2 gedrückt. Die Klemmstück-Aufnahme-Nut 22 ist auch in den Fig. 6 und 7 näher gezeigt. Die Klemmstück-Aufnahme-Nut 22 ist zum Ende 24 des Laufendes 2 hin Konus-förmig 23 ausgestaltet. Hierdurch wird das Laufende 2 in der Laufaufnahme 4 liegend in Richtung Systemhülse 3 gezogen, sodass der Lauf 1 definiert an der Systemhülse 3 anliegt.One of the clamping pieces 5 is pressed in a clamping piece receiving groove 22 at the running end 2. The sprag receiving groove 22 is also in the Fig. 6 and 7 shown in more detail. The clamping piece receiving groove 22 is conical 23 towards the end 24 of the running end 2. As a result, the running end 2 is drawn lying in the barrel holder 4 in the direction of the system sleeve 3, so that the barrel 1 lies against the system sleeve 3 in a defined manner.

Ebenfalls ersichtlich ist in Fig. 9 die eingreifende Verdreh-Sicherung des Laufendes 2 in der Laufaufnahme 4. Dabei ist ein am Laufende 2 ausgestalteter Vorsprung 8 in einer entsprechende Ausnehmung 9 an der Systemhülse 3 im eingesteckten Zustand des Laufendes 2 in der Laufaufnahme 4 in Eingriff. So wird sichergestellt, dass der Lauf 1 immer in einer definierten Lage an der Systemhülse 3 gehalten ist.It can also be seen in Fig. 9 the engaging anti-rotation lock of the barrel end 2 in the barrel holder 4. Here a projection 8 configured at the barrel end 2 engages in a corresponding recess 9 in the system sleeve 3 in the inserted state of the barrel end 2 in the barrel receptacle 4. This ensures that the barrel 1 is always held in a defined position on the system sleeve 3.

Die Fig. 10 bis 12 zeigen jeweils in einer schematischen Schnitt-Darstellung durch eine Systemhülse mit darin geklemmtem Laufende unterschiedliche Anzugsgrade der Spannschraube 7 gegen das Klemmstück 5.The 10 to 12 each show in a schematic sectional view through a system sleeve with a running end clamped therein different degrees of tightening of the clamping screw 7 against the clamping piece 5.

Durch die Enden 52 des Klemmstücks 5 - siehe auch Fig. 2 - wird mit dem gegenüberliegenden oberen Punkt 41 der Laufaufnahme 4 eine sehr stabile Drei-Punkt-Auflage bzw. -Klemmung des Laufendes 2 in der Laufaufnahme 4 gebildet.Through the ends 52 of the clamping piece 5 - see also Fig. 2 - With the opposite upper point 41 of the barrel holder 4, a very stable three-point support or clamping of the barrel end 2 in the barrel holder 4 is formed.

Da das Klemmstück 5 formelastisch ausgebildet ist, kann durch den Anzug der Spannschraube 7 eine vorwählbare Haltekraft auf das Laufende 2 ausgeübt werden.Since the clamping piece 5 is designed to be form-elastic, a preselectable holding force can be exerted on the running end 2 by tightening the clamping screw 7.

Fig. 11 zeigt eine schematische Schnitt-Darstellung durch die Systemhülse aus Fig. 10 mit stärker angezogener Spann-Schraube 7, und Fig. 12 entsprechend mit maximal angezogener Spann-Schraube 7. Fig. 11 shows a schematic sectional view through the system sleeve Fig. 10 with tightened tightening screw 7, and Fig. 12 correspondingly with the maximum tightening screw 7.

Die Laufklemmung ist durch Lösen der Spann-Schrauben 7 auf einfache Weise aufhebbar und der Lauf 1 kann einfach mit seinem Laufende 2 aus der Laufaufnahme 4 der Systemhülse 3 gezogen werden. So ist ein Laufwechsel als auch Wartung sehr einfach ermöglicht.The barrel clamp can be released in a simple manner by loosening the tensioning screws 7 and the barrel 1 can simply be pulled with its barrel end 2 out of the barrel holder 4 of the system sleeve 3. So a barrel change and maintenance is very easy.
