Description

Die vorliegende Erfindung betrifft eine Abzugsvorrichtung für eine Schußwaffe mit federbelastetem Schlagbolzen, umfassend einen Abzug, ein Zwischenelement und ein Fangstück, wobei der Schlagbolzen in der Spannstellung an dem Fangstück rastbar ist, wobei das Fangstück zur Schußabgabe quer zur Schlagbolzenrichtung freistellbar und zu Sicherungszwecken längs der Schlagbolzenrichtung zwischen der Spannstellung und einer die Schlagbolzenfeder entspannenden Sicherungsstellung versetzbar ist, und wobei das Fangstück beim Versetzen auf dem Zwischenelement gleitet, welches in Freistellrichtung des Fangstücks beweglich ist und dabei auf einer zur Schußabgabe ausrückbaren Rastkante des Abzugs rastet.The present invention relates to a trigger device for a firearm with spring-loaded firing pin, comprising a trigger, an intermediate element and a catching piece, wherein the firing pin is latched in the clamping position on the catching piece, wherein the catching piece for firing firing transversely to the firing pin direction freistellbar and for securing purposes along the firing pin direction between the clamping position and a securing position relaxing the firing pin spring is displaceable, and wherein the catching piece slides on displacement on the intermediate element, which is movable in the free-standing direction of the catching piece and engages on a releasable locking edge of the trigger for firing.

Versetzbare Fangstücke zum Spannen und Entspannen der Schlagbolzenfeder dienen zum vorübergehenden Sichern einer bereits geladenen Waffe, z.B. für den Transport oder auf der Pirsch. Zu diesem Zweck sind einerseits Konstruktionen bekannt (z.B. AT 409 548 B ), bei welchen das Fangstück mit seinem Auslöser auf einem im Gehäuse beweglichen Schlitten gelagert ist, der mit dem Abzug zusammenwirkt. Diese Art von Schlittenaufbau erfordert eine Vielzahl beweglicher Teile, was den Nachteil einer erhöhten Störungsanfälligkeit und eines erhöhten Platzbedarfs hat. Anderseits sind Konstruktionen auf dem Markt bekannt, bei welchen sich das Fangstück bei seiner Versetzung gegenüber seinem Auslöser bewegt, was die Genauigkeit des Schußauslösepunkts beeinträchtigt und aus diesem Grund auch die Gefahr einer unbeabsichtigten Schußauslösung bei zu geringer Rastüberdeckung in sich birgt.Removable catch pieces for tensioning and relaxing the firing pin spring serve for the temporary securing of an already loaded weapon, eg for transport or on the prowl. For this purpose, on the one hand constructions are known (eg AT 409 548 B ), in which the catching piece is mounted with its trigger on a carriage movable in the housing, which cooperates with the trigger. This type of carriage assembly requires a variety of moving parts, which has the disadvantage of increased susceptibility to failure and increased space requirements. On the other hand, constructions are known in the market, in which the catching piece moves in its displacement relative to its trigger, which affects the accuracy of the firing trigger point and for this reason also carries the risk of accidental firing at too low latching coverage in itself.

Eine Abzugsvorrichtung der einleitend genannten Art ist aus der DE 44 02 951 A1 bekannt. Das Zwischenelement ist ein schwenkbar gelagerter Hebel, welcher eine schräge Fläche für das Gleiten des Fangstücks beim Versetzen darbietet und sich damit bereits beim Spannen bewegt, was einer exakten Definition des Schußauslösepunkts abträglich ist.A take-off device of the aforementioned type is known from DE 44 02 951 A1 known. The intermediate element is a pivotally mounted lever, which presents an inclined surface for the sliding of the catching piece when moving and thus already moves during clamping, which is detrimental to an exact definition of the firing trigger point.

Die Erfindung setzt sich zum Ziel, die Nachteile des bekannten Standes der Technik zu überwinden und eine Abzugsvorrichtung für versetzbare Fangstücke zu schaffen, welche einerseits einfach und störungsunanfällig aufgebaut ist und anderseits eine exakte Definition des Schußauslösepunktes ermöglicht.The invention has the aim of overcoming the disadvantages of the known prior art and to provide a trigger device for displaceable catch pieces, which on the one hand is simple and not susceptible to interference and on the other hand allows an exact definition of the firing trigger point.

Dieses Ziel wird mit einer Abzugsvorrichtung der einleitend genannten Art erreicht, die sich gemäß der Erfindung dadurch auszeichnet, daß das Zwischenelement eine im Gehäuse der Schußwaffe linear führbare Raststange ist.This object is achieved with a trigger device of the aforementioned type, which is characterized according to the invention characterized in that the intermediate element is a lockable in the housing of the firearm locking bar.

Dies ermöglicht eine von der Verschiebung des Fangstücks unabhängige, exakt definierbare Rastüberdeckung zur Einstellung des Abzugsdruckpunktes.This allows an exactly definable latching cover for setting the withdrawal pressure point that is independent of the displacement of the catching piece.

Bevorzugt ist der Abzug im Gehäuse der Schußwaffe gelagert und trägt auf einem Absatz die Rastkante für das Zwischenelement, wodurch der Auslösepunkt für die Schußabgabe besonders exakt definiert werden kann.Preferably, the trigger is mounted in the housing of the firearm and carries on a shoulder the locking edge for the intermediate element, whereby the trigger point for the firing can be defined very precisely.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung gleitet das Fangstück über eine zwischenliegende Rolle auf dem Zwischenelement. Dies reduziert die Reibung des Fangstückes bei seiner Bewegung zwischen der Spannstellung und der Sicherungsstellung, sodaß die Spannstellung mit weniger Kraftaufwand erreicht werden kann als bei den bekannten Lösungen.According to a further preferred embodiment of the invention, the catching piece slides over an intermediate roller on the intermediate element. This reduces the friction of the catching piece in its movement between the clamping position and the securing position, so that the clamping position can be achieved with less force than in the known solutions.

Bevorzugt ist die Rolle am oberen Ende der Raststange gelagert, wodurch das Fangstück vereinfacht und gewichtsreduziert wird. Besonders günstig ist es, wenn die Rolle kugelgelagert ist, um die Reibung noch weiter zu verringern.Preferably, the roller is mounted at the upper end of the locking rod, whereby the catching piece is simplified and reduced weight. It is particularly favorable if the roller is ball-bearing in order to reduce the friction even further.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung wird vorgesehen, daß das Ausmaß der Rastüberdeckung des Zwischenelements mit der Rastkante des Abzugs mittels einer Justierschraube einstellbar ist. Dadurch kann der Auslösepunkt der Waffe justiert werden, und zwar unabhängig von den Stellungen des Fangstücks.According to a further advantageous embodiment of the invention it is provided that the extent of the locking overlap of the intermediate element with the locking edge of the trigger by means of an adjusting screw is adjustable. Thereby, the trigger point of the weapon can be adjusted, regardless of the positions of the catch piece.

Besonders günstig ist es, wenn das Fangstück durch einen Spannschieber zwischen der Spannstellung und der Sicherungsstellung versetzbar ist, welcher über einen Trieb auf das Betätigungselement wirkt, wie in der Technik an sich bekannt. Alternativ könnte das Fangstück auch durch ein Spannrad über einen entsprechenden Trieb betätigt werden.It is particularly advantageous if the catching piece by a cocking slide between the clamping position and the securing position is displaceable, which acts via a drive on the actuating element, as known per se in the art. Alternatively, the catching piece could also be actuated by a tensioning wheel via a corresponding drive.

Die erfindungsgemäße Abzugsvorrichtung eignet sich für jede Art von Schußwaffe mit Schlagbolzen und einem zu Sicherungszwecken versetzbaren Fangstück. Bevorzugt ist die Schußwaffe jedoch eine Repetierwaffe mit Drehkolbenverschluß, und insbesondere rastet der Schlagbolzen mit einer daran angesetzten Schlagbolzenfahne am Fangstück; bei diesen Waffentypen führt die Abzugsvorrichtung der Erfindung zu einer besonders geringen Bauhöhe und einfachen Integration.The trigger device according to the invention is suitable for any type of firearm with firing pin and a displaceable for securing purposes catching piece. Preferably, however, the firearm is a repeating weapon with rotary piston closure, and in particular locks the firing pin with an attached thereto firing pin flag on the catching piece; In these types of weapons, the trigger device of the invention leads to a particularly low profile and easy integration.

Die Erfindung wird nachstehend anhand eines in den beigeschlossenen Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. In den Zeichnungen zeigen
die Fig. 1 bis 3 die Abzugsvorrichtung der Erfindung im Schnitt in der Sicherungsstellung (Fig. 1), der Spannstellung (Fig. 2), sowie der abgeschlagenen Stellung (Fig. 3).
The invention will be explained in more detail with reference to an embodiment shown in the accompanying drawings. In the drawings show
the Fig. 1 to 3 the withdrawal device of the invention in section in the securing position ( Fig. 1 ), the clamping position ( Fig. 2 ), as well as the severed position ( Fig. 3 ).

In den Fig. 1 bis 3 sind der rückwärtige Teil eines Schlagbolzens 1, eine Abzugsvorrichtung 2, eine Spann- und Entspannvorrichtung 3 und (teilweise) ein Gehäuse 4 einer (nicht weiter dargestellten) Schußwaffe gezeigt. Der Schlagbolzen 1 wirkt auf eine Patrone im Patronenlager eines Laufs und ist zu diesem Zweck z.B. in einem Drehkolbenverschluß geführt, welche Teile dem Fachmann hinlänglich bekannt und daher hier nicht weiter dargestellt sind.In the Fig. 1 to 3 the rear part of a firing pin 1, a trigger device 2, a tensioning and relaxing device 3 and (partially) a housing 4 of a (not shown) firearm are shown. The firing pin 1 acts on a cartridge in the cartridge chamber of a barrel and is performed for this purpose, for example, in a rotary piston closure, which parts are well known to the skilled person and therefore not shown here.

Der Schlagbolzen 1 wird von einer (schematisch angedeuteten) Schlagbolzenfeder 5 in der Zeichnung nach links beaufschlagt und rastet dabei mit einer Schlagbolzenfahne 6 bei 7 an einem Fangstück 8. Das Fangstück 8 ist mit einem Lagerzapfen 9 in Langlöchern des Gehäuses 4 sowohl in Schlagbolzenlängs- als auch -querrichtung beweglich gelagert. Damit ist das Fangstück 8 einerseits zur Schußabgabe mittels der Abzugsvorrichtung 2 vom Schlagbolzen 1 freistellbar, sodaß sich dieser unter der Einwirkung der Schlagbolzenfeder 5 zum Aufschlag auf die Patrone nach links bewegt (siehe abgeschlagene Stellung in Fig. 3); anderseits kann das Fangstück 8 damit aber auch in Schlagbolzenlängsrichtung zwischen zwei verschiedenen Stellungen hin- und herbewegt bzw. versetzt werden, und zwar

  • einer entsicherten bzw. Spannstellung (Fig. 2), in welcher das Fangstück den Schlagbolzen 1 gegen die Kraft der Schlagbolzenfeder 5 gespannt hält (im Falle eines Drehkolbenverschlusses kann der Schlagbolzen 1 z.B. auch beim Repetier- bzw. Ladevorgang mittels eines herkömmlichen Kammerstengels in diese Stellung gebracht worden sein); und
  • einer entspannten Sicherungsstellung (Fig. 1), in welcher das Fangstück 8 in der Zeichnung nach links versetzt ist, um die Schlagbolzenfeder 5 zu entspannen (eine geringe Restspannung der Schlagbolzenfeder 5 kann hierbei belassen werden, um den - hier nicht dargestellten - vorderen Teil des Schlagbolzens 1 vom Patronenboden geringfügig zu beabstanden).
Das Fangstück 8 ist in diesem Sinne sowohl Teil der Abzugsvorrichtung 2 als auch Teil der Spann- und Entspannvorrichtung 3.The firing pin 1 is acted upon by a (schematically indicated) firing pin spring 5 in the drawing to the left and it engages with a firing pin flag 6 at 7 on a catching piece 8. The catching piece 8 is with a bearing pin 9 in slots of the housing 4 both in Schlagbolzenlängs- also transversely movable mounted. Thus, the catching piece 8 on the one hand to the firing by means of the trigger device 2 from the firing pin 1 freistellbar, so that this under the action of the firing pin spring 5 for impact on the cartridge moved to the left (see cut off position in Fig. 3 ); On the other hand, the catching piece 8 can thus be reciprocated or displaced between two different positions in firing pin longitudinal direction, namely
  • an unlocked or clamping position ( Fig. 2 ), in which the catching piece keeps the firing pin 1 tensioned against the force of the firing pin spring 5 (in the case of a rotary piston catch, the firing pin 1 can also have been brought into this position during the repeating or loading process by means of a conventional chamber stirrup); and
  • a relaxed securing position ( Fig. 1 ) in which the catching piece 8 is displaced to the left in the drawing to relax the firing pin spring 5 (a slight residual tension of the firing pin spring 5 can be left to slightly space the front part of the firing pin 1 from the bottom of the cartridge, not shown here) ).
The catching piece 8 is in this sense both part of the extraction device 2 and part of the tensioning and relaxing device. 3

Zur Aufnahme der genannten Versetzbewegung des Fangstückes 8 umfaßt die Abzugsvorrichtung 2 ein Zwischenelement in Form einer Raststange 10, die im Gehäuse 4 etwa vertikal linear geführt ist und an ihrem oberen Ende eine kugelgelagerte Rolle 11 trägt, auf welcher das Fangstück 8 hin und her gleiten kann. Die Raststange 10 rastet ihrerseits mit einem Absatz 12 an einer Rastkante 13, die an einem Absatz 14 eines Abzugs 15 ausgebildet ist. Der Abzug 15 ist bei 16 am Gehäuse 4 verschwenkbar gelagert und rückt beim Betätigen die Rastkante 13 von der Raststange 10 aus, sodaß sich diese nach unten bewegt (Fig. 3) und das Fangstück 8 vom Schlagbolzen 1 freistellt, wodurch der Schuß abgegeben wird. Das Ausmaß der Rastüberdeckung zwischen dem Absatz 12 der Raststange 10 und der Rastkante 13 des Abzugs 15 kann mittels einer Justierschraube 17 eingestellt werden.To accommodate said displacement movement of the catching piece 8, the extraction device 2 comprises an intermediate element in the form of a locking rod 10 which is guided approximately vertically vertically in the housing 4 and carries at its upper end a ball-bearing roller 11 on which the catching piece 8 can slide back and forth , The locking bar 10 in turn engages with a shoulder 12 at a locking edge 13 which is formed on a shoulder 14 of a trigger 15. The trigger 15 is pivotally mounted at 16 on the housing 4 and moves when pressed the locking edge 13 of the locking rod 10 so that it moves down ( Fig. 3 ) and the catching piece 8 from the firing pin 1 freestellt, whereby the shot is discharged. The extent of the locking overlap between the shoulder 12 of the locking rod 10 and the locking edge 13 of the trigger 15 can be adjusted by means of an adjusting screw 17.

Der Abzug 15 mit seiner Rastkante 13 kann einstückig oder - wie dargestellt - mehrteilig aus zwei relativ zueinander justierbaren Teilen ausgeführt sein, wie einem ein Züngel 18 umfassenden ersten Teil und einem den Absatz 14 mit der Rastkante 13 umfassenden zweiten Teil. Der Abzug 15 kann ferner mit einer Fallsicherung 19 und einem Verschlußfang 20 für das Abziehen eines Drehkolbenverschlusses ausgestattet werden, wie dem Fachmann an sich bekannt.The trigger 15 with its locking edge 13 may be in one piece or - as shown - in several parts of two adjustable relative to each other Be performed parts, such as a one-prong 18 comprehensive first part and the paragraph 14 with the locking edge 13 comprehensive second part. The trigger 15 may be further equipped with a drop guard 19 and a closure catch 20 for withdrawing a rotary piston closure, as known to those skilled in the art.

Die Spann- und Entspannvorrichtung 3 umfaßt ein Betätigungselement 21 in Form eines auf der Außenseite des Gehäuses 4 gleitverschieblich gelagerten Spannschiebers 21 mit einer Daumenangriffsfläche 22, welcher über einen Trieb 23 auf das Fangstück 8 einwirkt, um dieses in Schlagbolzenlängsrichtung zwischen seinen beiden Stellungen (Fig. 1 und 2) hin und her zu bewegen. Der Trieb 23 enthält eine Kulissensteuerung 24, über welche das Kraft/Weg-Übersetzungsverhältnis zwischen dem Betätigungselement 21 und dem Fangstück 8 definiert werden kann.The tensioning and relaxing device 3 comprises an actuating element 21 in the form of a slidingly mounted on the outside of the housing 4 cocking slide 21 with a thumb engaging surface 22 which acts via a drive 23 on the catching piece 8 to this in firing pin longitudinal direction between its two positions ( Fig. 1 and 2 ) to move back and forth. The drive 23 includes a slide control 24, via which the force / displacement ratio between the actuator 21 and the catching piece 8 can be defined.

Die Kulissensteuerung 24 umfaßt eine Schwenkkulisse 25, welche vom Spannschieber 21 über einen Lenker 26 verschwenkbar ist und an ihrem Außenumfang eine Steuerkurve 27 trägt. Auf der Steuerkurve 27 rollt ein Tastgestänge 28 mit einer kugelgelagerten Abtastrolle 29 ab und übersetzt die Form der Steuerkurve 27 über einen gehäusegelagerten zweiarmigen Hebel 30, welcher einen Zapfen 31 des Fangstück 8 ergreift, in eine Bewegung des Fangstücks 8.The slide control 24 comprises a pivoting gate 25, which is pivotable by the cocking slide 21 via a link 26 and carries on its outer periphery a cam 27. On the control cam 27, a Tastgestänge 28 rolls off with a ball-bearing cam follower 29 and translates the shape of the control cam 27 via a housing-mounted two-armed lever 30, which engages a pin 31 of the catching piece 8, in a movement of the catching piece. 8

Die Schwenkkulisse 25 ist zusätzlich mit einer Hilfs-Kulissenführung 32 in Form einer hinter der Steuerkurve 27 liegenden Nutführung ausgestattet, in welche das Tastgestänge 28 mit einem die Abtastrolle 29 überragenden Rückhaltestift 33 eingreift. Dadurch wird in jedem Betriebszustand eine zwangsweise Anlage der Abtastrolle 29 an der Steuerkurve 27 gewährleistet.The pivoting gate 25 is additionally equipped with an auxiliary link guide 32 in the form of a groove guide located behind the cam 27, in which the Tastgestänge 28 engages with a cam follower 29 protruding retaining pin 33. As a result, a forced abutment of the cam follower 29 on the control cam 27 is ensured in each operating condition.

Bei der Bewegung des Spannschiebers 21 in den Fig. 1 und 2 von rechts nach links schwenkt die Schwenkkulisse 25 nach unten, die Taststange 28 gleitet auf der Steuerkurve 27 aufreitend nach links und das Fangstück 8 bewegt sich durch den Hebel 29 nach rechts gegen die Kraft der Schlagbolzenfeder 5. Mit Hilfe eines Druckknopfes 36 auf dem Spannschieber 21 kann eine selbsteinrastende Rastklinke 37 zur Verrastung des Lenkers 26 in der Spannstellung C wieder gelöst werden.During the movement of the cocking slide 21 in the Fig. 1 and 2 from right to left pivots the pivot gate 25 down, the probe rod 28 slides on the control cam 27 aufreitend to the left and the catching piece 8 moves through the lever 29 to the right against the force of the firing pin spring 5. Mit Help a push button 36 on the cocking slide 21, a self-locking latch 37 for locking the handlebar 26 in the clamping position C can be solved again.

Alle Dreh- bzw. Schwenklager in der Vorrichtung werden bevorzugt mittels Wälzlagern ausgeführt, um die Reibung zu reduzieren.All rotary or pivot bearings in the device are preferably carried out by means of rolling bearings in order to reduce the friction.
