Abstract

In a trigger mechanism for automatic fire arms with single-shot or continuous fire, a catch arranged below the breech block has a nose which engages with the breech block, and can pivot as a result of friction-type connection with a trigger rod which can be moved by the trigger. An interrupter arm arranged on the trigger rod projects upward against the breech block. In the single-shot position, the upper end of said arm projects into the path of motion of a part of the breech block and is depressed by the breech block in order to release the friction-type connection between the trigger rod and the catch. In the continuous fire position, said end is thrust out of the path of motion of the breech block by an eccentric which acts on the trigger rod.

Description

Abzugseinrichtung für automatische Feuerwaffen Trigger device for automatic firearms
Die Erfindung betrifft eine Abzugseinrichtung für automa¬ tische Feuerwaffen für Einzel- und Dauerfeuer mit einem Abzug und einer von diesem bewegbaren Abzugsstange, durch welche die Fangklinke für das Verschlußstück betätigt wird.The invention relates to a trigger device for automatic firearms for single and continuous fire with a trigger and a trigger rod movable by this, by means of which the catch pawl for the breech piece is actuated.
Abzugseinrichtungen für den Verschluß von automatischen Feuerwaffen, mit welchen wahlweise Einzelschüsse oder Serien von Schüssen als Dauerfeuer abgegeben werden können, sind in den unterschiedlichsten Ausführungsformen bekanntgeworden. Ihr wesentlicher Mangel liegt darin begründet, daß sie einen verhältnismäßig komplizierten konstruktiven Aufbau haben und vor allem deshalb außer¬ ordentlich empfindlich gegenüber unterschiedlichsten Einflüssen sind, die zu Störungen und zur vorübergehenden Unbrauchbarkeit der Waffe Anlaß geben.Trigger devices for the closure of automatic firearms, with which either individual shots or series of shots can be fired as continuous fire, have become known in a wide variety of embodiments. Their main deficiency lies in the fact that they have a relatively complicated structural design and, above all, are therefore extremely sensitive to a wide variety of influences which give rise to malfunctions and the temporary uselessness of the weapon.
Der Erfindung liegt die Aufgabe zugrunde, eine möglichst einfache, rationell zu fertigende und störungsunanfällige Abzugseinrichtung zu schaffen, die im Falle auftretender Störungen rasch und einfach zerlegt und nach Austausch beschädigter Teile in einfacher Weise wieder zusammenge¬ baut werden kann, um die Waffe in kürzester Frist wieder funktionsfähig zu machen.The object of the invention is to provide a trigger device which is as simple as possible, can be produced efficiently and is not susceptible to faults, which can be dismantled quickly and easily in the event of malfunctions and can be reassembled in a simple manner after replacement of damaged parts in order to mount the weapon in the shortest possible time to make it work again.
Diese Aufgabe wird durch die insbesondere im Patentan¬ spruch 1 angegebenen Merkmale gelöst. Weitere Merkmale der erfindungsgemäß ausgebildeten Abzugseinrichtung gehen aus den Unteransprüchen wie auch aus der nachfolgenden Be¬ schreibung eines in den Figuren 1 und 2 der Zeichnung schematisch dargestellten bevorzugten Ausführungsbeispiels hervor. Es zeigen:This object is achieved by the features specified in particular in patent claim 1. Further features of the trigger device designed according to the invention are based the subclaims and also from the following description of a preferred exemplary embodiment shown schematically in FIGS. 1 and 2 of the drawing. Show it:
Fig. 1 eine Seitenansicht der Abzugseinrichtung in derjenigen Stellung, in welcher mit der Waffe Einzelfeuer abgegeben werden kann, undFig. 1 is a side view of the trigger device in the position in which single fire can be fired with the weapon, and
Fig. 2 eine Seitenansicht der Abzugseinrichtung nach Fig. 1 in derjenigen Stellung, die ein Dauer¬ feuer ermöglicht.FIG. 2 shows a side view of the trigger device according to FIG. 1 in the position which enables a continuous fire.
Wie aus den Figuren 1 und 2 ersichtlich, weist die erfin¬ dungsgemäß ausgebildete Abzugseinrichtung 11 eine im wesentlichen parallel zur horizontalen Gleitbahn des Ver¬ schlußstücks 12 liegende Fangklinke 13 auf, die mit einer nach oben gerichteten Fangnase 14 versehen ist, die eine hintere vertikale Flanke 15 und eine vordere, nach vorn abwärts geneigte Flanke 16 aufweist. Die Fangklinke 13 hält, wie aus Fig. 1 ersichtlich, mit ihrer Fangnase 14 •das Verschlußstück 12 in seiner hinteren Lage fest, indem sie in eine Nut 17 eingreift, deren hintere Kante eine vertikale Rast- bzw. Anschlagfläche 18 aufweist, die an der vertikalen Flanke 15 der Fangnase 14 anliegt. Die Fangklinke 13 ist um den Lagerzapfen 19 schwenkbar ge¬ lagert, und ist von einer Druckfeder 20 beaufschlagt, die das hintere Ende der Fangklinke 13 nach oben gegen das Verschlußstück 12 drückt. Die Fangklinke 13 ist als Winkelhebel ausgebildet. Der. rechtwinklig zu dem hori¬ zontalen Schenkel 21 angeordnete Schenkel 22 ragt von der Lagerstelle um den Lagerzapfen 19 vertikal nach unten und besitzt an seinem unteren Ende einen Ausschnitt 23, in welchen das vordere Ende 24 der horizontalen und zum Schenkel 21 der Fangklinke 13 im wesentlichen parallelen Abzugsstange 25 hineinragt. Die Abzugsstange 25 ist an ihrem hinteren Ende 26 durch einen Gelenkbolzen 27 mit dem oberen Ende 28 des um den ortsfesten Lagerzapfen 29 schwenkbar gelagerten Abzug 30 verbunden. Auf die Abzugs¬ stange 25 wirkt eine beispielsweise am hinteren Ende 26 angreifende Zugfeder 31 ein, die die Abzugsstange 25 ständig nach hinten zieht; anstelle einer Zugfeder kann auch eine Druckfeder vorgesehen sein.As can be seen from FIGS. 1 and 2, the trigger device 11 designed according to the invention has a catch pawl 13 which is essentially parallel to the horizontal slideway of the closure piece 12 and which is provided with an upwardly directed catch lug 14 which has a rear vertical flank 15 and has a front flank 16 which is inclined downwards to the front. The catch pawl 13 holds, as can be seen from FIG. 1, with its catch lug 14 • the locking piece 12 in its rear position by engaging in a groove 17, the rear edge of which has a vertical latching or stop surface 18, which on the vertical flank 15 of the catch 14 is present. The catch pawl 13 is pivotally mounted about the bearing pin 19 and is acted upon by a compression spring 20 which presses the rear end of the catch pawl 13 upwards against the closure piece 12. The catch pawl 13 is designed as an angle lever. The. Leg 22, which is arranged at right angles to the horizontal leg 21, projects vertically downward from the bearing point around the bearing pin 19 and has a cutout 23 in at its lower end which protrudes the front end 24 of the horizontal trigger rod 25, which is essentially parallel to the leg 21 of the catch pawl 13. The trigger rod 25 is connected at its rear end 26 by a hinge pin 27 to the upper end 28 of the trigger 30 pivotally mounted about the fixed journal 29. A pull spring 31, which acts, for example, on the rear end 26, acts on the trigger rod 25 and continuously pulls the trigger rod 25 backwards; a compression spring can also be provided instead of a tension spring.
Die Abzugsstange 25 besitzt in ihrem vorderen Bereich einen nach oben gegen das Verschlußstück 12 ragenden Unterbrecherarm 32, dessen oberes Ende 33 abgerundet ist und in die Nut 17 an der Unterseite des Verschlußstücks 12 eingreift und in der Bewegungsbahn der Anschlagfläche 18 am Verschlußstück 12 liegt. Etwa unterhalb des Unter¬ brecherarms 32 ist eine auf die Abzugsstange 25 ein¬ wirkende und diese nach oben drückende Feder 34 angeord¬ net. Das vordere, in den Ausschnitt 23 des vertikalen Schenkels 22 der Fangklinke 13 eingreifende Ende 24 der Abzugsstange 25 ist in ihrer Höhe verjüngt, so daß eine obere Anschlagschulter 35 und eine untere Anschlagschulter 36 gebildet sind, die in der üblichen Stellung der Abzugs¬ stange 25 oberhalb des Ausschnitts 23 bzw. in der unteren Stellung der Abzugsstange 25 an der hinteren Fläche 37 des nach unten ragenden Schenkels 22 der Fangklinke 13 an¬ liegen.The trigger rod 25 has in its front area an upwardly projecting against the locking piece 12 interrupter arm 32, the upper end 33 is rounded and engages in the groove 17 on the underside of the locking piece 12 and lies in the movement path of the stop surface 18 on the locking piece 12. A spring 34 which acts on the trigger rod 25 and pushes it upward is arranged approximately below the interrupter arm 32. The front end 24 of the trigger rod 25, which engages in the cutout 23 of the vertical leg 22 of the catch pawl 13, is tapered in height, so that an upper stop shoulder 35 and a lower stop shoulder 36 are formed, which in the usual position of the trigger rod 25 Above the cutout 23 or in the lower position of the trigger rod 25 lie against the rear surface 37 of the leg 22 of the catch pawl 13 projecting downwards.
Oberhalb der Abzugsstange 25 befindet sich ein Exzenter 38, der durch einen außen an der Waffe befindlichen Aus¬ wahlhebel 39 um 90° verschwenkt werden kann. In der in Fig. 1 dargestellten Stellung liegt die Abzugsstange 25 an dem abgeflachten Abschnitt 40 des Exzenter 38 an, wodurch die Abzugsstange 25 die in Fig. 1 dargestellte obere Lage einnehmen kann, in welcher die obere Anschlagschulter 35 an der Rückseite 37 des Schenkels 22 der Fangklinke 13 oberhalb des Ausschnitts 23 anliegt.Above the trigger rod 25 there is an eccentric 38 which can be pivoted through 90 ° by a selection lever 39 located on the outside of the weapon. In the position shown in Fig. 1, the trigger rod 25 is present the flattened section 40 of the eccentric 38, whereby the trigger rod 25 can assume the upper position shown in FIG. 1, in which the upper stop shoulder 35 bears against the rear 37 of the leg 22 of the catch pawl 13 above the cutout 23.
Bei Betätigung des Abzugs 30 wird dieser um den Lager¬ zapfen 29 geschwenkt, wodurch die Abzugsstange 25 nach vorn, d.h. in der Zeichnung ganz links, bewegt wird. Mittels der Anschlagschulter 35 wird der Schenkel 22 der Fangklinke 13 nach links und der horizontale Schenkel 21 nach unten geschwenkt. Dadurch gleitet die Fangnase 14 von der Rast- bzw. Anschlagfläche 18 ab und das Verschlußstück 12 kann durch die nicht dargestellte Vorholfeder nach links bewegt werden, um das Verschlußstück in die Ver¬ schlußlage zu bringen. Bei dieser Bewegung wird der Unter¬ brecherarm 32, dessen oberes Ende 33 in der Bewegungs¬ bahn der Rastfläche 18 liegt, nach unten gedrückt, wodurch die Anschlagschulter 35 von der hinteren Fläche 37 des vertikalen Schenkels 22 der Fangklinke 13 abgleitet, wodurch die zuvor kraftschlüssige Verbindung zwischen diesem und der Abzugsstange 25 aufgehoben wird. Der hori¬ zontale Schenkel 21 der Fangklinke 13 wird nach oben ge¬ drückt, so daß nach Abfeuerung eines Schusses der Abzug von der Fangnase 14 der Fangklinke 13 wieder in der hinteren Lage festgehalten wird. Bei jeder einzelnen Be¬ tätigung des Abzugs 30 kann somit nur jeweils ein einziger Schuß abgegeben werden.When the trigger 30 is actuated, it is pivoted about the bearing pin 29, as a result of which the trigger rod 25 is moved forward, i.e. in the drawing on the far left. The leg 22 of the catch pawl 13 is pivoted to the left and the horizontal leg 21 downwards by means of the stop shoulder 35. As a result, the catch lug 14 slides off the latching or stop surface 18 and the closure piece 12 can be moved to the left by the forward spring, not shown, in order to bring the closure piece into the closed position. During this movement, the interrupter arm 32, the upper end 33 of which lies in the path of movement of the latching surface 18, is pressed down, as a result of which the stop shoulder 35 slides off the rear surface 37 of the vertical leg 22 of the catch pawl 13, as a result of which the previously non-positive Connection between this and the trigger rod 25 is canceled. The horizontal leg 21 of the catch pawl 13 is pressed upwards, so that after a shot is fired, the trigger from the catch nose 14 of the catch pawl 13 is held in the rear position again. Each time the trigger 30 is actuated, only a single shot can be fired.
Soll jedoch mit der Waffe Dauerfeuer geschossen werden, wobei eine Serie von Schüssen automatisch hintereinander abgegeben wird, solange der Abzug 30 betätigt wird, so ist der Auswahlhebel 39 in die in Fig. 2 dargestellte Dauer- feuerposition zu verschwenken, wodurch der Exzenter 38 die Abzugsstange 25 in die untere Lage verstellt, in welcher die untere Anschlagschulter 36 an der Rückseite 37 des vertikalen Schenkels 22 der Fangklinke 13 anliegt und der nach oben ragende Unterbrecherarm 32 so weit nach unten gezogen ist, daß dessen oberes Ende außerhalb bzw. unter¬ halb der Bewegungsbahn der Rastfläche 18 des Verschlu߬ stücks 12 liegt. Wird bei einer derartigen Einstellung des Auswahlhebels 39 der Abzug 30 betätigt, verschwenkt die Abzugsstange 25 den horizontalen Schenkel 21 der Fang¬ klinke 13 nach unten und hält diesen in der unteren Posi¬ tion fest, d.h. daß dann das Verschlußstück 12 ungehindert vor und zurück bewegt werden kann, solange der Abzug nach hinten gezogen bleibt. Wird der Abzug 30 losgelassen, gerät die Fangnase 14 wieder in die Bahn des Verschlu߬ stücks 12 und hält dieses in seiner hinteren Lage fest.If, however, continuous fire is to be fired with the weapon, a series of shots being fired automatically one after the other as long as the trigger 30 is actuated, the selection lever 39 must be in the continuous mode shown in FIG. fire position to pivot, whereby the eccentric 38 moves the trigger rod 25 in the lower position, in which the lower stop shoulder 36 rests against the rear 37 of the vertical leg 22 of the catch pawl 13 and the upstanding arm 32 is pulled down so far that the upper end of which lies outside or below the path of movement of the latching surface 18 of the closure piece 12. If the trigger 30 is actuated in such a setting of the selection lever 39, the trigger rod 25 pivots the horizontal leg 21 of the catch pawl 13 downward and holds it in the lower position, ie that the locking piece 12 then moves freely back and forth as long as the trigger remains pulled back. If the trigger 30 is released, the catch 14 comes back into the path of the closure piece 12 and holds it in its rear position.
Die erfindungsgemäß ausgebildete Abzugseinrichtung hat den Vorteil, daß sie in ihrer konstruktiven Ausbildung außer¬ ordentlich einfach und robust ist und praktisch nur aus vier Teilen besteht, die gelenkig miteinander gekoppelt sind. Für den Fall, daß trotzdem einmal Teile der Abzugs¬ einrichtung ausgewechselt werden müssen, so läßt sich dies in außerordentlich einfacher Weise rasch vornehmen. The trigger device designed according to the invention has the advantage that it is extraordinarily simple and robust in its construction and practically consists of only four parts which are articulated to one another. In the event that parts of the trigger device still have to be replaced, this can be done very quickly in an extremely simple manner.
