Description

Die Erfindung betrifft ein Abzugssystem für Handfeuerwaffen nach dem Oberbegriff des Anspruchs 1.The invention relates to a trigger system for handguns according to the preamble of claim 1.

Es sind bereits sogenannte Double Action Only Abzugssysteme als reiner Spannabzug bekannt, bei denen der Schlaghammer bei jedem Schuss zunächst über den Abzug gespannt werden muß. Durch derartige Abzugssysteme wird bei einer Waffe eine hohe Sicherheit gewährleistet, da sie nach dem Schiessen ohne zusätzliches Entspannen weggesteckt oder abgelegt werden kann. Allerdings weisen die herkömmlichen Double Action Only Abzugssysteme einen gleichbleibenden Abzugsweg und einen relativ hohen Abzugswiderstand auf.There are already so-called Double Action Only trigger systems known as pure tension trigger, in which the percussion hammer must first be stretched over the trigger with each shot. Such trigger systems ensure a high level of security in a weapon, since they can be put away or stored after shooting without additional relaxation. However, the conventional Double Action Only trigger systems have a constant trigger travel and a relatively high trigger resistance.

Es gibt auch bereits teilvorgespannte Abzugssysteme, die einen kürzeren Abzugsweg aufweisen und das Auslösen eines Schusses mit geringerem Abzugswiderstand ermöglichen. Vielfach ist jedoch bei diesen Abzugssystemen ein zweites Abziehen nach einem Zündversager nicht möglich.There are also partially preloaded trigger systems that have a shorter trigger path and allow the triggering of a shot with less trigger resistance. In many cases, however, a second removal after a Zündversager is not possible with these trigger systems.

Aus der US 2 846 925 ist ein Abzugssystem für eine Handfeuerwaffe nach dem Oberbegriff des Patentanspruchs 1 bekannt. Dieses Abzugssystem enthält ebenfalls einen Schlaghammer, eine dem Schlaghammer zugeordnete Fangklinke, einen Abzug und eine mit diesem zusammenwirkenden Abzugsschiene, die eine erste Rastkante zum Eingriff mit einer hinteren Feuerrast des Schlaghammers und eine zweite Rastkante zum Eingriff mit einer gegenüber der ersten Feuerrast nach vorne versetzt am Schlaghammer angeordneten zweiten Feuerrast enthält. Bei diesem bekannten Abzugssystem weist die nach vorne versetzte Feuerrast des Schlaghammers jedoch einen größeren Abstand von einer durch den Schlaghammer verlaufenden Durchgangsbohrung für eine Schlaghammerachse als die erste Feuerrast auf.From the US Pat. No. 2,846,925 a trigger system for a handgun according to the preamble of claim 1 is known. This trigger system also includes a percussion hammer, a pawl associated with the sear, a trigger and cooperating with this trigger rail having a first latching edge for engagement with a rear fire stop of the percussion hammer and a second latching edge for engagement with a relative to the first fire latch forward offset on Impact hammer arranged second fire catch contains. In this known trigger system, however, the forward offset fire catch of the percussion hammer at a greater distance from a running through the percussion hammer through hole for a percussion hammer axis as the first fire rest.

In der US 3 152 418 ist ebenfalls ein Abzugsystem einer Handfeuerwaffe offenbart, bei dem eine vordere erste Feuerrast des Schlaghammers einen größeren Abstand zur Schlaghammerachse als eine nach hinten versetzte zweite Feuerrast aufweist.In the US 3,152,418 is also disclosed a trigger system of a handgun in which a front first fire stop of the percussion hammer has a greater distance from the percussion hammer axis than a rearwardly offset second fire stop.

Aufgabe der Erfindung ist es, ein Abzugssystem für Handfeuerwaffen zu schaffen, das einen geringen Abzugswiderstand aufweist und auch bei Zündversagern funktionstüchtig bleibt.The object of the invention is to provide a trigger system for handguns, which has a low trigger resistance and remains functional even with Zündversagern.

Diese Aufgabe wird durch ein Abzugssystem mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a trigger system with the features of claim 1. Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims.

Die Funktionsweise des erfindungsgemäßen Abzugssystems entspricht der eines teilvorgespannten Double Action Only Abzugssystems. Durch Repetieren (manuell bzw. durch den zurücklaufenden Verschluss nach der Abgabe des ersten Schusses) gelangt das Abzugssystem in eine teilvorgespannte Funktionsstellung, in der die gespeicherte Energie der den Schlaghammer beaufschlagenden Schlaghammerfeder noch nicht ausreicht, um eine Patrone zu zünden. Durch Betätigung des Abzugs kann der Schlaghammer aus dieser Stellung heraus zunächst weiter gespannt und anschließend zur Auslösung eines Schusses freigegeben werden. Über die erste Rastkante der Abzugsschiene und die zugehörige erste Feuerrast des Schlaghammers kann das Abzugssystem aufgrund des günstigen Hebels zum Drehpunkt des Schlaghammers mit geringerem Kraftaufwand betätigt werden. Nach dem ersten Schuss besteht aber auch die Möglichkeit, das Abzugssystem über die zweite Rastkante der Abzugsschiene und die zugehörige zweite Feuerrast mit erheblich kürzerem Abzugsweg, jedoch etwas höherem Kraftaufwand zu betätigen. Wenn sich die Abzugsschiene durch Loslassen des Abzuges in Richtung des Schlaghammers bewegt, kann die zweite Rastkante bereits früher wieder in Eingriff mit der zugehörigen zweiten Feuerrast gelangen und es ist eine Schußauslösung mit kürzerem Abzugsweg möglich. Allerdings ist hierbei aufgrund des ungünstigeren Hebels von der in Funktion befindlichen zweiten Rastkante und der zweiten Feuerrast zum Drehpunkt des Schlaghammers ein etwas höherer Kraftaufwand erforderlich. Mit Hilfe der zweiten Rastkante und der zugehörigen zweiten Feuerrast ist außerdem auch eine nochmalige Betätigung des Abzugssystems nach einem Zündversager mit dann allerdings etwas höherem Kraftaufwand und längerem Abzugsweg möglich.The operation of the trigger system according to the invention corresponds to that of a semi-prestressed Double Action Only trigger system. By repeating (manually or by the returning closure after the delivery of the first shot), the trigger system enters a partially preloaded functional position in which the stored energy of the hammer acting on the percussion hammer spring is not sufficient to ignite a cartridge. By operating the trigger, the percussion hammer can initially be further tensioned out of this position and then released to trigger a shot. About the first locking edge of the trigger rail and the associated first fire stop of the percussion hammer, the trigger system can be operated with less effort due to the cheap lever to the pivot point of the percussion hammer. But after the first shot, it is also possible to operate the trigger system on the second locking edge of the trigger rail and the associated second fire with a considerably shorter Abzugsweg, but somewhat higher force. If the trigger rail moves by releasing the trigger in the direction of the percussion hammer, the second locking edge can get back into engagement earlier with the associated second fire door and it is a shot triggering with a shorter trigger path possible. However, this is due to the less favorable lever from the function in function of the second locking edge and the second fire catch to the pivot point of the percussion hammer a slightly higher force required. With the help of the second locking edge and the associated second fire rest also a repeated actuation of the trigger system for a Zündversager with then, however, a little higher effort and longer withdrawal path is possible.

Das in den Figuren 1 bis 4 schematisch dargestellte Abzugssystem einer Handfeuerwaffe enthält einen Schlaghammer 1 mit einer Fangklinke 2, einen Abzug 3 und eine mit diesem gelenkig verbundene Abzugsschiene 4, über die der Schlaghammer 1 bei der Betätigung des Abzugs 3 zunächst entgegen der Kraft einer nicht dargestellten Schlaghammerfeder gespannt und anschließend zum Auslösen eines Schusses freigegeben wird. Die Abzugsschiene 4 wird über eine den Abzug 3 in eine vordere Ausgangsstellung beaufschlagende - nicht gezeigte - Abzugsfeder nach hinten und eine ebenfalls nicht gezeigte Abzugsschienenfeder nach oben beaufschlagt.That in the FIGS. 1 to 4 schematically shown trigger system of a handgun contains a percussion hammer 1 with a sear 2, a trigger 3 and an articulated with this trigger rail 4, about the hammer 1 during operation of the trigger 3 initially tensioned against the force of a hammer, not shown, and then to trigger a shot is released. The trigger rail 4 is acted upon by a trigger 3 in a front starting position acting - not shown - trigger spring to the rear and a trigger rail spring also not shown upwards.

Wie aus der unteren Darstellung von Figur 1 hervorgeht, ist der Schlaghammer 1 um eine Schlaghammerachse 5 verschwenkbar zwischen zwei voneinander beabstandeten Seitenteilen 6 eines Trägerelements 7 angeordnet. Zwischen den beiden Seitenteilen 6 des Trägerelements 7 ist auch die Fangklinke 2 um einen Querstift 8 verschwenkbar montiert. Durch diese Fangklinke 2 wird der Schlaghammer 1 in einer teilvorgespannten Stellung gehalten, wie im folgenden noch näher erläutert ist. Besonders gut ist die Anordnung der Fangklinke 2 in den jeweils oberen Darstellungen der Figuren 1 bis 4 erkennbar, in denen das vordere der beiden Seitenteile 6 des Trägerelements 7 weggelassen ist. Auch der Abzug 3 ist an dem Trägerelement 7 angeordnet. Er enthält ein schräg nach oben weisendes seitliches Anlenkteil 9 mit einem seitlich vorstehenden Gelenkzapfen 10, an dem das vordere Ende der Abzugsschiene 4 angelenkt ist. Der Abzug 2 mit dem Anlenkteil 9 und dem Gelenkzapfen 10 ist bei der gezeigten Ausführung einteilig ausgeführt.As from the lower part of FIG. 1 shows, the percussion hammer 1 is arranged about a hammer axis 5 pivotally between two spaced-apart side parts 6 of a support member 7. Between the two side parts 6 of the support member 7 and the sear 2 is mounted pivotably about a transverse pin 8. By this fishing pawl 2 of the percussion hammer 1 is held in a partially prestressed position, as will be explained in more detail below. Particularly good is the arrangement of the sear 2 in the respective upper representations of FIGS. 1 to 4 recognizable in which the front of the two side parts 6 of the carrier element 7 is omitted. The trigger 3 is also arranged on the carrier element 7. It contains an obliquely upward-pointing lateral coupling part 9 with a laterally projecting pivot pin 10, on which the front end of the trigger rail 4 is articulated. The trigger 2 with the coupling part 9 and the pivot pin 10 is made in one piece in the embodiment shown.

Wie besonders aus Figur 5 hervorgeht, enthält der Schlaghammer 1 an seiner Unterseite einen Steuerradius 11 und eine erste untere Feuerrast 12. Der Schlaghammer weist ferner an seiner der Abzugsschiene 4 zugewandten Seite eine Freifräsung 13 mit einer zweiten oberen Feuerrast 14 auf. Oberhalb der Freifräsung 13 enthält der Schlaghammer 1 außerdem eine Querbohrung 15 für die in Figur 1 dargestellte Schlaghammerachse 5, über die der Schlaghammer 1 zwischen den Seitenteilen 6 des Trägerelements 7 verschwenkbar angeordnet ist. Die zweite Feuerrast 14 ist oberhalb der ersten Feuerrast 12 und gegenüber dieser nach vorne versetzt angeordnet. An der Vorderseite des Schlaghammers 1 ist außerdem ein Sicherungsnocken 16 mit einer Sicherungsrast 17 zum Eingriff der Fangklinke 2 vorgesehen.How special FIG. 5 As can be seen, the percussion hammer 1 on its underside a control radius 11 and a first lower fire stop 12. The percussion hammer further has on its deduction rail 4 side facing a free-cropping 13 with a second upper Feuerrast 14. Above the free cut 13 of the percussion hammer 1 also includes a transverse bore 15 for in FIG. 1 illustrated hammer axis 5, over which the percussion hammer 1 between the side parts 6 of the support member 7 is pivotally mounted. The second fire stop 14 is disposed above the first fire stop 12 and offset from this forward. At the front of the percussion hammer 1, a safety cam 16 is also provided with a safety catch 17 for engagement of the sear 2.

Die in Figur 6 gesondert dargestellte Abzugsschiene 4 weist an ihrem nach oben abgewinkelten vorderen Ende eine Bohrung 18 zum Aufstecken auf den seitlich vorstehenden Gelenkzapfen 10 des Abzugs 3 auf. An ihrem nach innen abgekröpften hinteren Ende enthält die Abzugsschiene 4 einen nach oben vorstehenden Steuernocken 19 und einen in Richtung des Schlaghammers 1 vorstehenden Abschnitt 20 mit einer ersten unteren Rastkante 21 und einer dazu seitlich und nach oben versetzten zweiten Rastkante 22. Die erste Rastkante 21 wirkt mit der ersten Feuerrast 12 zusammen, während die zweite obere Rastkante 22 in die Freifräsung 13 eingreift und mit der zweiten Feuerrast 14 zusammenwirkt. Bei der gezeigten Ausführung besteht der Abschnitt 20 aus einem nach innen rechtwinklig umgebogenen hinteren Teil der Abzugsschiene 4. Die Abzugsschiene 4 weist außerdem eine schräg nach oben verlaufende Steuerschräge 23 zur Anlage an einem nach außen vorstehenden Teil der Schlaghammerachse 5 auf.In the FIG. 6 separately shown trigger rail 4 has at its upwardly angled front end a bore 18 for attachment to the laterally projecting pivot pin 10 of the trigger 3 on. At its inwardly cranked rear end of the trigger rail 4 includes an upwardly projecting cam 19 and a projecting toward the percussion hammer 1 section 20 with a first lower locking edge 21 and a laterally and upwardly offset second locking edge 22. The first locking edge 21 acts with the first fire stop 12 together, while the second upper locking edge 22 engages in the milled groove 13 and cooperates with the second fire stop 14. In the embodiment shown, the section 20 consists of an inwardly bent at right angles rear part of the trigger rail 4. The trigger rail 4 also has an obliquely upwardly extending control slope 23 for engagement with an outwardly projecting part of the hammer axis 5.

In Figur 7 ist die Fangklinke 2 gezeigt. Die gabelförmige Fangklinke 2 weist eine obere Fangklinkenrastkante 24 und zwei nach unten ragende parallele Schenkel 25 und 26 mit fluchtenden Lagerbohrungen 27 bzw. 28 für den Gelenkstift 8 auf. Die Fangklinke 2 enthält außerdem einen seitlich vorstehenden Fangklinkennocken 29, der durch ein in Figur 1 gezeigtes schräges Langloch 30 in dem zur Abzugsschiene 4 gewandten Seitenteil 6 des Trägerelements 7 ragt von diesen zum Eingriff mit dem Steuernocken 18 der Abzugsschiene 4 nach außen vorsteht.In FIG. 7 the satchel 2 is shown. The fork-shaped sear 2 has an upper catch latch notch 24 and two downwardly projecting parallel legs 25 and 26 with aligned bearing bores 27 and 28 for the hinge pin 8. The satchel 2 also includes a laterally projecting catching pawl cam 29, which by a in FIG. 1 shown oblique slot 30 in the side facing the trigger rail 4 side part 6 of the support member 7 protrudes from this for engagement with the control cam 18 of the trigger rail 4 projects outwardly.

Im folgenden wird die Funktionsweise des erfindungsgemäßen Abzugssystems anhand der Figuren 1 bis 4 erläutert.In the following the operation of the trigger system according to the invention with reference to the FIGS. 1 to 4 explained.

In Figur 1 ist das Abzugssystem in einer teilvorgespannten Funktionsstellung gezeigt, in welche das Abzugssystem durch manuelles Repetieren bzw. durch den zurücklaufenden Verschluss nach der Abgabe eines Schusses gelangt. In dieser teilvorgespannten Funktionsstellung wird der Schlaghammer 1 durch die in Eingriff mit der Sicherungsrast 17 stehende Fangklinke 2 in einer teilvorgespannten Stellung gehalten, in der die Kraft der nicht dargestellten Schlaghammerfeder jedoch noch nicht ausreicht, um eine Patrone zu zünden. Der Steuernocken 19 der Abzugsschiene 4 liegt mit seiner hinteren Seite an einem seitlich vorstehenden Teil der Schlaghammerachse 5 an. Die eine Rastkante 22 der Abzugsschiene 4 befindet sich funktionslos in der Freifräsung 13 des Schlaghammers 1, während die andere Rastkante 21 in Eingriff mit der zugehörigen Feuerrast 12 des Schlaghammers 1 steht.In FIG. 1 the trigger system is shown in a partially preloaded functional position, in which the trigger system passes by manual repetition or by the returning closure after the delivery of a shot. In this partially preloaded functional position of the percussion hammer 1 is held in a teilvorgespannten position by the standing in engagement with the locking catch 17 sear 2, in which the force of the hammer, not shown, but not enough to ignite a cartridge. The control cam 19 of the trigger rail 4 rests with its rear side on a laterally projecting part of the hammer axis 5. The one locking edge 22 of the trigger rail 4 is located without function in the free-cutting 13 of the percussion hammer 1, while the other locking edge 21 is in engagement with the associated fire stop 12 of the percussion hammer 1.

Durch Betätigung des Abzugs 3 wird der teilvorgespannte Schlaghammer 1 gemäß Figur 2 über die Abzugsschiene 4 entgegen der nicht gezeigten Schlaghammerfeder weiter gespannt. Während des Spannvorgangs wird die Abzugsschiene 4 über die an der Schlaghammerachse 5 anliegende Steuerschräge 23 der Abzugsschiene 4 in Richtung des Pfeils nach unten bewegt, bis die Rastkante 21 der Abzugsschiene 4 außer Eingriff mit der zugehörigen Feuerrast 12 des Schlaghammers 1 kommt und dieser zur Auslösung eines Schusses freigegeben wird. Die andere Rastkante 22 der Abzugsschiene 4 befindet sich während dieses Vorgangs funktionslos in der Freifräsung 13 des Schlaghammers 1. Im Verlauf des Spannvorgangs wird die Fangklinke 2 über den Steuernocken 19 der Abzugsschiene 4 und den Fangklinkennocken 29 nach vorne in eine Position verschwenkt und gehalten, in der ein Abschlagen des Schlaghammers 1 ermöglicht wird.By pressing the trigger 3 of the partially preloaded percussion hammer 1 according FIG. 2 on the trigger rail 4 against the hammer hammer, not shown, further tensioned. During the clamping operation, the trigger rail 4 is moved over the voltage applied to the impact hammer axis 5 control slope 23 of the trigger rail 4 in the direction of the arrow until the locking edge 21 of the trigger rail 4 is disengaged from the associated fire stop 12 of the percussion hammer 1 and this to trigger a Shot is released. The other locking edge 22 of the trigger rail 4 is located during this process without function in the free-cutting 13 of the percussion hammer 1. In the course of the clamping operation, the sear 2 is pivoted on the control cam 19 of the trigger rail 4 and the catch cam 29 forward to a position and held in the knocking of the percussion hammer 1 is made possible.

In Figur 3 ist das vorstehend beschriebene Abzugssystem in einer Position nach einem Zündversager gezeigt. Der Schlaghammer 1 befindet sich in einer vollständig entspannten vorderen Ausgangsstellung. Die Abzugsschiene 4 befindet sich mit der zweiten Rastkante 22 in der Freifräsung 13 hinter der zugehörigen Feuerast 14, während die erste Rastkante 21 an dem Steuerradius 11 des Schlaghammers anliegt.In FIG. 3 For example, the exhaust system described above is shown in a position after a misfire. The percussion hammer 1 is in a completely relaxed front starting position. The trigger rail 4 is located with the second locking edge 22 in the free-cutting 13 behind the associated Feuerast 14, while the first locking edge 21 rests against the control radius 11 of the percussion hammer.
