Description

Die Erfindung beschäftigt sich mit einem Verschlusssystem einer insbesondere fremd angetriebenen Waffe sowie der Sicherheit der Waffe, wobei sichergestellt werden muss, dass ein Schuss erst dann ausgelöst wird, wenn der Verschluss mit dem Waffenrohr verriegelt ist. Dazu wird das Verschlusssystem mit einem Sicherheitssystem ergänzt.
Aus der DE 10 2009 056 735 A1 ist eine fremd angetriebene Waffe mit einer Munitionszuführung bekannt, bei der die Munition vor den Verschluss gelegt und diese vom Verschluss einem Waffenrohr linear zugeführt wird. In einer der Schaltzyklen wird der Verschluss mit dem Waffenrohr verriegelt und die Munition bzw. Patrone gezündet. Dabei ist sichergestellt, dass das Zünden bei voll verriegeltem Verschluss erfolgt.
Einen selektiven sowie zuschaltbaren Verschluss- und / oder Munitionsantrieb offenbaren die DE 10 2010 051 047 A1 sowie die DE 10 2010 027 636 A1 . Auch hier wird eine Verschlusssicherheit vorausgesetzt. Der in DE 10 2006 037 306 A offenbarte Verschluss ist Ausgangslage für das Verschlusssystem nach Anspruch 1.The invention is concerned with a locking system of a particular foreign-powered weapon and the safety of the weapon, wherein it must be ensured that a shot is triggered only when the closure is locked to the gun barrel. For this purpose, the locking system is supplemented with a security system.
From the DE 10 2009 056 735 A1 is a foreign-powered weapon with an ammunition feeder known in which the ammunition placed in front of the shutter and this is fed linearly from the shutter to a gun barrel. In one of the switching cycles, the closure is locked with the gun barrel and ignited the ammunition or cartridge. This ensures that the ignition takes place when the lock is fully locked.
A selective and switchable lock and / or ammunition drive reveal the DE 10 2010 051 047 A1 as well as the DE 10 2010 027 636 A1 , Again, a lock security is required. The in DE 10 2006 037 306 A The disclosed closure is the starting point for the closure system according to claim 1.

Der Erfindung stellt sich die Aufgabe, ein Verschlusssystem für eine fremd angetriebene, hinten verriegelnde Waffe aufzuzeigen sowie eine Sicherheit des Verschlusssystems zu garantieren.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgeführt.
Der Erfindung liegt die Idee zugrunde, das Verschlusssystem dadurch sicherer zu machen, dass zumindest eine Schlagbolzensicherheit in das Verschlusssystem eingebunden wird.The object of the invention is to provide a locking system for a foreign-powered, rear locking weapon and to guarantee a security of the closure system.
The object is achieved by the features of claim 1. Advantageous embodiments are listed in the subclaims.
The invention is based on the idea of making the closure system safer in that at least one firing pin safety is integrated into the closure system.

Der Transport des Verschlusssystems wird, wie beispielsweise in der DE 10 2009 056 735 A1 beschrieben, hierbei angenommen bzw. vorausgesetzt. Auf die darin beschriebene Arbeitsweise wird hiermit Bezug genommen. Das Verschlusssystem umfasst zumindest einen Verschlussträger zur Aufnahme und zum Transport eines Verschlusskopfes. Der Verschlussträger und der Verschlusskopf bilden den Verschluss.The transport of the closure system is, as in the DE 10 2009 056 735 A1 described, here assumed or assumed. The procedure described therein is hereby incorporated by reference. The closure system comprises at least one closure carrier for receiving and transporting a closure head. The closure carrier and the closure head form the closure.

An diesem Verschlussträger ist seitlich angebracht ein vorlaufender Stößel eingebunden, der gegen eine waffenfeste Verriegelungshülse anschlägt, während der Verschluss bzw. der Verschlusskopf sich dem Verriegelungsabschnitt des Waffenrohres nähert. Der Verschlussträger wird weiter in Richtung Waffenrohr bewegt. Durch den an die Verriegelungshülse anschlagenden Stößel, der nunmehr nicht mehr weiter bewegt werden kann, erfolgt das Spannen eines im Verschluss befindlichen Schlagbolzens. Der weiterlaufende Verschlussträger bewegt sich weiter, sodass der Verschlusskopf an / in die Verriegelungshülse an die Verriegelungswarzen der Waffenseite eingreifen und den Verschlusskopf verriegeln kann. Es erfolgt das Verriegeln des Verschlusses über einen Bolzen am Verschlusskopf, der entlang einer Verriegelungskurve im Verschlussträger geführt wird, wenn dieser noch geringfügig verschoben wird. Das Bewegen des Bolzens entlang der Verriegelungskurve bewirkt ein Drehen des Verschlusskopfes zum Verriegeln des Verschlusses.Attached laterally to this closure carrier is a leading ram which abuts against a weapon-resistant locking sleeve, while the closure or the closure head approaches the locking portion of the weapon barrel. The fastener carrier is moved further in the direction of the weapon barrel. By the abutting the locking sleeve plunger, which can now no longer be moved, there is the tensioning of a firing pin located in the closure. The continuing closure carrier continues to move so that the closure head on / in the locking sleeve can engage the locking arms of the weapon side and lock the closure head. There is a locking of the closure via a bolt on the closure head, which is guided along a locking curve in the lock carrier, if this is still slightly shifted. Moving the bolt along the locking cam causes the locking head to rotate to lock the shutter.

In diesem zeitlichen Ablauf erfolgt auch das Spannen einer Vorstellfeder innerhalb des Stößels sowie einer Feder des Schlagbolzens durch den hinteren Teil des Stößels, der eine Schlagbolzen-Hauptfahne des Schlagbolzens unterstellt. Wenn der Verschlusskopf zum Verriegeln im Verschlussträger gedreht wird, verstellt sich die Schlagbolzen-Hauptfahne zum hinteren Teil des Stößels und wird dadurch freigegeben, sodass der Schlagbolzen freiliegt und ein Schuss ausgelöst werden kann. Für diese Freigabe weist das hintere Teil des Stößels eine Formgebung auf, die es der Schlagbolzenfahne ermöglicht, im regulärem Ablauf des Verriegelns des Verschlusses entlang einer so genannten Abzugskante nach vorne zu gleiten. Diese Formgebung bildet die Steuerkurve für die Schlagbolzen- Hauptfahne. Damit das hintere Teil des Stößels nach erfolgtem Schuss wieder hinter die Schlagbolzen-Hauptfahne greifen kann, kann das hintere Teil des Stößels abgesteuert werden, sodass die Schlagbolzenfahne wieder hinter das hintere Teil des Stößels eingreifen kann bei Entriegelung des Verschlusskopfes.In this time sequence also takes place the tensioning of an advance spring within the plunger and a spring of the firing pin through the rear part of the plunger, which assumes a firing pin main flag of the firing pin. When the lock head is rotated to lock in the lock carrier, the main striker flag moves to the rear of the slide and is released thereby exposing the striker and firing a shot. For this release, the rear part of the plunger has a shape that allows the striker lug to slide forward along a so-called trigger edge in the normal course of locking the closure. This shape forms the cam for the main firing pin. In order for the rear part of the plunger to be able to grip behind the firing pin main lug after the shot has taken place, the rear part of the plunger can be deactivated, so that the firing pin lug can engage behind the rear part of the plunger again when the closure head is unlocked.

Nun kann in der Praxis nicht ausgeschlossen werden, dass es beispielsweise zum Brechen des Stößels in der Zuführposition, also beim Spannen des Schlagbolzens, kommen kann.Now it can not be ruled out in practice that, for example, the ram may break in the feed position, ie when the firing pin is tensioned.

Um hier eine ausreichende Sicherheit zu schaffen, ist vorgesehen, eine Zwischenhülse zwischen dem Verschlusskopf und dem Verschlussträger einzubinden. Diese verhindert, dass der Schlagbolzen in dieser Situation, wenn die Schlagbolzen-Hauptfahne vom Stößel z.B. nicht mehr unterstellt ist, ausgelöst wird. Der Schlagbolzen kann bei Bruch maximal auf die Hülsenkante der Zwischenhülse aufschlagen. Er wird an dieser Zwischenhülse gehalten und kann nicht auf das Anzündhütchen der Patrone auftreffen bzw. in dieses eindringen.In order to provide sufficient security, it is provided to incorporate an intermediate sleeve between the closure head and the closure carrier. This prevents the firing pin in this situation, when the firing pin main flag from the plunger, for example. is no longer subordinated, is triggered. The firing pin can strike a maximum on the sleeve edge of the intermediate sleeve at break. He is held on this intermediate sleeve and can not impinge on the primer of the cartridge or penetrate into this.

Für eine optimale Sicherung ist des Weiteren vorgesehen, dass in dieser Zwischenhülse eine Steigung (Schräge) eingebunden ist. So kann beim Entriegeln und bevor der Verschlusskopf entriegelt ist, der Schlagbolzen über die Schlagbolzenfahne in eine Sicherheitsposition überführt werden.For optimum safety, it is further provided that an incline (bevel) is incorporated in this intermediate sleeve. Thus, when unlocking and before the locking head is unlocked, the firing pin on the firing pin flag can be transferred to a safety position.

Vorgeschlagen wird somit ein Verschlusssystem mit einem Verschlussträger sowie einem vom Verschlussträger getragenen Verschlusskopf und einem darin befindlichen Schlagbolzen. Der Schlagbolzen verfügt über eine Schlagbolzen-Hauptfeder, die über einen Stößel am / im Verschlussträger gespannt wird. In dieses Verschlusssystem wird ein Sicherungssystem integriert, umfassend eine Verschlusshülse, die zwischen dem Verschlusskopf und dem Verschlussträger eingebunden ist. In der bevorzugten Ausführung ist eine Schräge in der hinteren Stirnwand der Verschlusshülse eingebunden, die die Sicherheit erhöht.Thus, a closure system with a closure carrier and a closure head carried by the closure carrier and a firing pin located therein are proposed. The firing pin has a striker main spring, which is tensioned by a plunger on / in the bolt carrier. In this closure system, a security system is integrated, comprising a closure sleeve which is integrated between the closure head and the closure carrier. In the preferred embodiment, a slope is incorporated in the rear end wall of the closure sleeve which increases safety.

Um zu vermeiden, dass der Bolzen 6, der als Verriegelungsbolzen des Verschlusssystems 1 dient, aufgrund seiner Trägheit im Verschlussträger 2 bereits zu drehen beginnt, ohne dass der Verschlusskopf 3 sich nach vorne bewegen würde, ist der Winkelhebel 5 in das Verschluss- 1 und Sicherheitssystem 10 eingebunden. Der Winkelhebel 5 bildet die Sperre für den Bolzen 6, sodass dieser sich nicht eigenständig bewegen kann. Erreicht der Verschlussträger 2 den Bereich der Verriegelungshülse 11, wird der Winkelhebel 5 entlang der Steuerkurve 14 aus der Ausnehmung 3.3 und damit gegenüber dem Verschlusskopf 3 abgesenkt, sodass der Winkelhebel 5 den Verschlusskopf 3 zum Drehen / Verriegeln freigibt. Eine Feder 5.1 am Winkelhebel 5 unterstützt die Funktion des Winkelhebels 5.In order to avoid that the bolt 6, which serves as a locking bolt of the closure system 1, already starts to rotate due to its inertia in the bolt carrier 2 without the bolt head 3 moving forward, the bell crank 5 is in the bolt 1 and safety system 10 integrated. The angle lever 5 forms the lock for the bolt 6 so that it can not move independently. Reached the lock carrier 2, the range of the locking sleeve 11, the angle lever 5 is lowered along the control cam 14 from the recess 3.3 and thus against the closure head 3, so that the angle lever 5 releases the closure head 3 for turning / locking. A spring 5.1 on the angle lever 5 supports the function of the angle lever. 5

Wenn der Verschlussträger 2 die Verriegelungshülse 11 erreicht hat, trifft der Stößel 4 mit seiner Spitze 4.5 auf die Anschlagfläche 11.3 der Verriegelungshülse 11 auf. Der Stößel 4 ist voreilend, sodass eine Vorstellfeder 4.2 am Ende 4.3 des Stößels 4 gespannt wird, bevor der Bund 3.2 des Verschlusses 3 an der Verriegelungshülse 11 anschlägt. Der Stößel 4 unterstellt den Schlagbolzen 7, wobei insbesondere das Ende 4.3 des Stößels 4 eine Schlagbolzen-Hauptfahne 7.2 des Schlagbolzens 7 unterstellt. Das Spannen der Vorstellfeder 4.2 erfolgt über einen geringen Weg (abhängig des Weges der Spitze 4.5). Der Stößel 4 selbst hat nun keine Möglichkeit mehr, weiter nach vorne geführt zu werden. Der Verschlussträger 2 läuft weiter, bis der Verschlusskopf 3 mit seinem Bund 3.2 die Durchführung 11.1 und dabei die Verriegelungswarzen 11.2 erreicht hat. Mit der Unterstellung der Schlagbolzen-Hauptfahne 7.2 durch den Stößel 4 wird die Schlagbolzenfeder 7.1 gespannt.
Bei der nachfolgenden Bewegung des Verschlussträgers 2 wird der Verriegelungsbolzen 6, der durch den Winkelhebel 5 freigegeben wurde, entlang seiner Verriegelungskurve im Verschlussträger 2 (oben) geführt. Mit dem Ablaufen der Verriegelungskurve durch den Verriegelungsbolzen 6 (D1), erfolgt eine Drehung (D2) des Verschlusskopfes 3 um ca. 30° und damit das Verriegeln des Verschlusses bzw. des Verschlusskopfes 3 in der Verriegelungshülse 11. Hierbei greifen die Verriegelungswarzen 11.2 sowie die Verschlusskopfwarzen 3.1 hinter- bzw. ineinander. Der Verschluss ist über den Verschlusskopf 3 ist in der Waffe verriegelt.
Mit dem Drehen des Verschlusskopfes 3 im Verschlussträger 2 verdreht sich auch die Schlagbolzen-Hauptfahne 7.2, sodass diese über eine Abzugskante 4.4 des Stößels 4 nach vorne ausweichen kann. Der Schlagbolzen 7 im Verschlusskopf 3 kann sich unter der Kraft der Schlagbolzenfeder 7.1 nach vorne bewegen, ein Schuss wird ausgelöst.
Das Ende 4.3 des Stößels 4 weist für die Schussauslösung ein Formgebung auf, die es der Schlagbolzen-Hauptfahne 7.2 ermöglicht, im regulärem Ablauf des Verriegelns des Verschlusses entlang der so genannten Abzugskante 4.4 am Stößel 4 nach vorne zu gleiten, wodurch der Schlagbolzen 7 freigegeben wird. Die Formgebung bildet die Steuerkurve für die Schlagbolzen-Hauptfahne 7.2.
Zur Vermeidung, dass der Schlagbolzen 7 ungewollt ausgelöst werden kann, beispielsweise weil der Stößel 4 in Zuführposition und damit beim Spannen der Schlagbolzenfeder 7.1 des Schlagbolzens 7 bricht, sieht das Sicherungssystem 10 eine Zwischenhülse 20, auch Verschlusshülse genannt, zwischen dem Verschlusskopf 3 und dem Verschlussträger 2 vor. Sollte der Stößel 4 brechen und damit die Unterstellung der Schlagbolzen-Hauptfahne 7.2 aufgehoben werden, kann diese maximal auf die Kante 22 der Verschlusshülse 20 aufschlagen, sodass der Schlagbolzen 7 selbst nicht für seinen gesamten Weg zur Schussauslösung freigegeben wird. Während der Verschlusskopf 3 in seinen Stillstandzeiten in der jeweiligen Position verbleibt, ist die drehfest eingebundene Verschlusshülse 20 (Fig. 7) ihrerseits in Bewegung (linear).When the closure carrier 2 has reached the locking sleeve 11, the tappet 4 strikes the stop surface 11.3 of the locking sleeve 11 with its tip 4.5. The plunger 4 is leading, so that a projection spring 4.2 at the end 4.3 of the plunger 4 is tensioned before the collar 3.2 of the shutter 3 abuts against the locking sleeve 11. The plunger 4 assumes the firing pin 7, wherein in particular the end 4.3 of the plunger 4 a striker main flag 7.2 of the firing pin 7 assumes. The tensioning of the preliminary spring 4.2 takes place over a short distance (depending on the path of the tip 4.5). The plunger 4 itself now has no way to continue to be led forward. The lock carrier 2 continues to run until the closure head 3 with its collar 3.2, the implementation 11.1 and thereby has reached the locking lugs 11.2. With the assumption of the firing pin main flag 7.2 by the plunger 4, the firing pin spring 7.1 is stretched.
During the subsequent movement of the closure carrier 2, the locking bolt 6, which has been released by the angle lever 5, is guided along its locking curve in the closure carrier 2 (top). With the passage of the locking cam through the locking pin 6 (D 1 ), there is a rotation (D 2 ) of the closure head 3 by about 30 ° and thus the locking of the closure or the closure head 3 in the locking sleeve 11. This attack the locking lugs 11.2 as well as the locking head warts 3.1 behind or into each other. The closure is over the lock head 3 is locked in the weapon.
With the rotation of the closure head 3 in the lock carrier 2, the firing pin main lug 7.2 also rotates so that it can move forward over a trigger edge 4.4 of the tappet 4. The firing pin 7 in the closure head 3 can move under the force of the firing pin spring 7.1 forward, a shot is fired.
The end 4.3 of the plunger 4 has for the shot triggering on a shape that allows the firing pin main flag 7.2, in the regular course of locking the shutter along the so-called trigger edge 4.4 on the plunger 4 to slide forward, whereby the firing pin 7 is released , The shaping forms the cam for the striker main flag 7.2.
To avoid that the firing pin 7 can be triggered unintentionally, for example, because the plunger 4 breaks in feed position and thus when tensioning the firing pin spring 7.1 of the firing pin 7, the backup system 10 sees an intermediate sleeve 20, also called a closure sleeve, between the closure head 3 and the closure carrier 2 ago. If the plunger 4 break and thus the subordination of the firing pin main flag 7.2 are repealed, this can maximally strike the edge 22 of the closure sleeve 20 so that the firing pin 7 itself is not released for its entire path to the shot firing. While the closure head 3 remains in its idle time in the respective position, the non-rotatably engaged closure sleeve 20 (FIG. Fig. 7 ) in turn (linear).

Das Entriegeln und Zurückfahren des Verschlusssystems 1 erfolgt entsprechend der einzelnen Verriegelungsschritte für das Verriegeln entgegengesetzt.The unlocking and retraction of the closure system 1 is carried out in the opposite manner according to the individual locking steps for locking.

Damit das Ende 4.3 des Stößels 4 nach erfolgtem Schuss wieder hinter die Schlagbolzen-Hauptfahne 7.2 greifen kann, kann das Ende 4.3 des Stößels 4 abgesteuert werden, sodass die Schlagbolzenfahne 7.2 bei Entriegelung und Drehung des Verschlusskopfes 3 hinter das Ende 4.3 des Stößels 4 eingreifen kann, wenn der Verschlusskopf 3 über den Verschlussträger 2 in seine hintere Position überführt wird. In einer bevorzugten Ausgestaltung sind das Ende 4.3 als auch die Schlagbolzen-Hauptfahne 7.2 gabelförmig ausgeführt und greifen mit diesen ineinander.In order for the end 4.3 of the plunger 4 to be able to grip behind the firing pin main lug 7.2 again after the shot has taken place, the end 4.3 of the ram 4 can be deactivated, so that the striker lug 7.2 can engage behind the end 4.3 of the ram 4 when the closure head 3 is unlocked and rotated when the closure head 3 is transferred via the lock carrier 2 in its rear position. In a preferred embodiment, the end 4.3 and the striker main flag 7.2 are fork-shaped and engage with each other.

Die Weiterführung der Erhöhung der Sicherheit kann eine Steigung bzw. Schräge 21 in der Kante 22 der Verschlusshülse 20 eingebunden werden. Die vordere (obere) Gerade 21.1 bilden dabei eine Sicherheitsposition und die hintere (tiefere) 21.2 eine Abschlagposition des Schlagbolzens 7. Bereits beim Entriegeln aber bevor der Verschluss 3 entriegelt ist, wird durch die Drehung des Verschlusses 3 aufgrund der Wirkungsweise des Verriegelungsbolzen 6, der nunmehr die Verriegelungskurve 2.1 in entgegengesetzter Richtung abfährt und den Verschlusskopf 3 entgegen der Drehung D2 dreht, die Schlagbolzen-Hauptfahne 7.2 über die Schräge 21 in seine Sicherheitsposition überführt (Fig. 7). Sollten nunmehr der Stößel 4 brechen, kann der Schlagbolzen 7 nicht nach vorne ausbrechen. Die Verschlusshülse 20 hält den Schlagbolzen 7 an der oberen Gerade 21.1 der Schräge 21 fest.The continuation of the increase in safety, a slope or bevel 21 in the edge 22 of the closure sleeve 20 are involved. The front (upper) straight line 21.1 form a safety position and the rear (lower) 21.2 a knock position of the firing pin 7. Already when unlocking but before the shutter 3 is unlocked, is due to the rotation of the shutter 3 due to the operation of the locking pin 6, the now the locking curve 2.1 moves in the opposite direction and the locking head 3 rotates counter to the rotation D 2 , the firing pin main flag 7.2 transferred over the slope 21 in its safety position ( Fig. 7 ). Should now break the plunger 4, the firing pin 7 can not break forward. The closure sleeve 20 holds the firing pin 7 at the top straight 21.1 of the slope 21 firmly.
