Abstract

A two-armed spring-loaded trigger lever (1) pivotable into the cocked position oppositely to the trigger-pulling direction interacts with a two-armed spring-loaded intermediate lever (4) which blocks the striker (12) in the catch position via a further intermediate lever (11). The two-armed intermediate lever (4) is pivotable about an axis (5) arranged on the second arm (3) of the trigger lever (1), between two stops (7, 8), of which at least the first (7) is arranged on the second arm (3) of the trigger lever (1). In the shotgun trigger position of the trigger lever (1), the intermediate lever (4) bears against the first stop (7) and its axis (5) is on this side, but in the cocked position of the trigger lever (1) it is immediately on the far side of a plane (A) defined by the bearing line (10) of the further intermediate lever (11) on the two-armed intermediate lever (4) and the axis (6) of the trigger lever (1). The second adjustable stop (8) for the two-armed intermediate lever (4) is preferably arranged on the housing (9) of the trigger mechanism, but can likewise be provided on the trigger lever (3). <IMAGE>

Description

Die Erfindung betrifft eine Abzugseinrichtung mit Rückstecher, insbesondere für Jagdgewehre, bei der ein zweiarmiger, federbeaufschlagter Abzugshebel, der entgegen der Abzugseinrichtung in die eingestochene Stellung verschwenkbar ist, mit einem zweiarmigen, federbeaufschlagten Zwischenhebel zusammenwirkt, der über einen weiteren Zwischenhebel den Schlagbolzen in Fangstellung sperrt.The invention relates to a trigger device with a set-back, in particular for hunting rifles, in which a two-armed, spring-loaded trigger lever, which can be pivoted against the trigger device into the inserted position, interacts with a two-arm, spring-loaded intermediate lever, which locks the firing pin in the catch position via a further intermediate lever.

Eine derartige Abzugseinrichtung ist beispielsweise der AT-PS 338 658 zu entnehmen. Der zweite Arm des Abzugshebels liegt zu der Flintenabzugsstellung an einen ersten Zwischenhebel an, der um eine gehäusefeste Achse schwenkbar ist. In dieser Stellung sperrt der erste Zwischenhebel einen als Abzugsstollen bezeichneten, zweiten Zwischenhebel, der eine Fahne des Schlagbolzens blokkiert. Zwischen den beiden Zwischenhebeln ist zur Rückstellung eine Druckfeder angeordnet. Eine Bewegung des Abzugshebels in Abzugsrichtung überträgt sich auf den ersten Zwischenhebel, der den zweiten Zwischenhebel entriegelt. Dieser wiederum gibt den Schlagbolzen frei. Die Stecheinrichtung, die in Form eines Rückstechers vorgesehen ist, mit deren Hilfe der Weg des Abzugshebels bis zur Freigabe des Schlagbolzens auf ein Minimum beschränkt wird, weist eine Blattfeder auf, die zwischen einem gehäusefesten, federnden und verstellbaren Anschlag und dem Abzugshebel eingesetzt ist. In der normalen Flintenabzugsstellung verläuft die Wirkungslinie der Feder oberhalb der Achse des Abzugshebels. In der eingestochenen Stellung verläuft die Wirkungslinie der Feder durch die Achse des Abzugshebels, der entgegen der Abzugsbewegung an einem gehäusefesten Anschlag, nicht jedoch am ersten Zwischenhebel anliegt. Eine geringfügige Bewegung in Abzugsrichtung bewegt die Wirkungslinie aus der Achse des Abzugshebels, sodaß auf den Abzugshebel ein Drehmoment ausgeübt wird, das diesen auf den ersten Zwischenhebel schlägt, dessen Bewegung den zweiten Zwischenhebel und schließlich den Schlagbolzen freigibt.Such a trigger device can be found, for example, in AT-PS 338 658. The second arm of the trigger lever is in contact with the shotgun trigger position against a first intermediate lever which is pivotable about an axis fixed to the housing. In this position, the first intermediate lever locks a second intermediate lever, referred to as an extraction stud, which blocks a flag of the firing pin. A compression spring is arranged for resetting between the two intermediate levers. A movement of the trigger lever in the trigger direction is transferred to the first intermediate lever, which unlocks the second intermediate lever. This in turn releases the firing pin. The lancing device, which is provided in the form of a set-back, with the help of which the path of the trigger is limited to a minimum until the firing pin is released, has a leaf spring which is inserted between a housing-fixed, resilient and adjustable stop and the trigger. In the normal shotgun trigger position, the line of action of the spring runs above the trigger lever axis. In the inserted position, the line of action of the spring runs through the axis of the trigger which, contrary to the trigger movement, bears against a stop fixed to the housing, but not against the first intermediate lever. A slight movement in the trigger direction moves the line of action out of the axis of the trigger lever, so that a torque is exerted on the trigger lever. which strikes the first intermediate lever, the movement of which releases the second intermediate lever and finally the firing pin.

Die für die Stecheinrichtung benötigte Blattfeder greift, wie erwähnt, am Abzugshebel an und bildet einen elastischen Teil eines Kniehebelsystems zur Überwindung der labilen Gleichgewichtslage. Sie liegt zudem an einer verhältnismäßig leicht zugänglichen Stelle des Abzugsgehäuses, an der das Eindringen von Schmutz, Schnee usw. nicht zu vermeiden und eine Beschädigung nicht ausgeschlossen ist.The leaf spring required for the lancing device, as mentioned, engages the trigger lever and forms an elastic part of a toggle lever system to overcome the unstable equilibrium position. It is also located at a relatively easily accessible point on the fume cupboard where dirt, snow, etc. cannot be prevented and damage cannot be ruled out.

Die Erfindung hat es sich daher zur Aufgabe gestellt, eine Abzugseinrichtung der eingangs genannten Art zu schaffen, bei der ein federnder Teil im Kniehebelsystem nicht erforderlich ist, da für die Erzeugung des Drehmoments auf den Abzugshebel bei Auslösung von der eingestochenen Stellung eine andere Feder, insbesondere die Schlagbolzenfeder eingesetzt wird.The invention has therefore set itself the task of creating a trigger device of the type mentioned, in which a resilient part in the toggle lever system is not required, since another spring, in particular for generating the torque on the trigger lever when triggered from the inserted position the firing pin spring is used.

Erfindungsgemäß wird dies dadurch erreicht, daß der zweiarmige Zwischenhebel um eine auf dem zweiten Arm des Abzugshebels angeordnete Achse zwischen zwei Anschlägen verschwenkbar ist, von denen zumindest der erste am zweiten Arm des Abzugshebels angeordnet ist, wobei in der Flintenabzugsstellung des Abzugshebels der Zwischenhebel am ersten Anschlag anliegt, und seine Achse diesseits, in der eingestochenen Stellung des Abzugshebels jedoch unmittelbar jenseits einer Ebene liegt, die durch die Auflagelinie des weiteren Zwischenhebels auf dem zweiarmigen Zwischenhebel und die Achse des Abzugshebels bestimmt ist.According to the invention this is achieved in that the two-armed intermediate lever can be pivoted about an axis arranged on the second arm of the trigger between two stops, at least the first of which is arranged on the second arm of the trigger, the intermediate lever at the first stop in the shotgun trigger position of the trigger abuts, and its axis on this side, but in the inserted position of the trigger lever is immediately beyond a plane which is determined by the contact line of the further intermediate lever on the two-armed intermediate lever and the axis of the trigger lever.

Da der zweiarmige Zwischenhebel in der Flintenabzugsstellung an dem, am zweiten Arm des Abzugshebels angeordneten Anschlag anliegt und seine Achse mit Abstand zur genannten Ebene liegt, preßt eine über den zweiten Zwischenhebel fließende Kraft einer Feder, insbesondere eine Kraftkomponente der Schlagbolzenfeder den zweiarmigen Zwischenhebel gegen den Anschlag am Abzugshebel, sodaß die beiden eine starre Einheit bilden. Bei Betätigung des Abzugshebels wird daher der zweiarmige Zwischenhebel solange mitbewegt, bis er den.nächstfolgenden Zwischenhebel.und in weiterer Folge den Schlagbolzen freigibt.Since the two-armed intermediate lever in the shotgun trigger position rests against the stop arranged on the second arm of the trigger lever and its axis lies at a distance from the plane mentioned, a force of a spring flowing via the second intermediate lever, in particular a force component of the firing pin spring, presses the two-arm intermediate lever against the stop on the trigger, so that the two form a rigid unit. When the trigger is actuated, the two-armed intermediate lever is therefore moved until it releases the next intermediate lever and subsequently the firing pin.

Wird der Abzugshebel hingegen in die eingestochene Stellung bewegt, löst sich der zweiarmige Zwischenhebel vom Anschlag am zweiten Arm des Abzugshebels und verschwenkt entgegengesetzt zum Abzugshebel bis zur Anlage am zweiten Anschlag. Dabei überschwenkt die Achse des zweiarmigen Zwischenhebels geringfügig die genannte Ebene, die durch die Auflagelinie des nächstfolgenden Zwischenhebels und die Achse des Abzugshebels verläuft, in einem Ausmaß, daß sie sich gerade wieder im stabilen Gleichgewicht befindet. Es genügt daher die geringste Bewegung des Abzugshebels, um die Achse des zweiarmigen Zwischenhebels wieder über die genannte Ebene zurückzubewegen, worauf die über den zweiten Zwischenhebel einwirkende Kraft den zweiarmigen Zwischenhebel gegen den ersten Anschlag am Abzugshebel schlägt, und in weiterer Folge die Wucht des Aufschlages die ab diesem Augenblick wieder starre Einheit von zweiarmigem Zwischenhebel und Abzugshebel weiterverschwenkt, bis der nächstfolgende Zwischenhebel freigegeben und damit der Schlagbolzen ausgelöst wird.However, if the trigger is moved to the inserted position, the two-armed intermediate lever releases from the stop on the second arm of the trigger and pivots in the opposite direction to the trigger until it contacts the second stop. The axis of the two-armed intermediate lever swings slightly above the plane mentioned, which runs through the contact line of the next intermediate lever and the axis of the trigger, to such an extent that it is again in stable equilibrium. It therefore suffices the slightest movement of the trigger to move the axis of the two-armed intermediate lever back over the above-mentioned level, whereupon the force acting on the second intermediate lever strikes the two-armed intermediate lever against the first stop on the trigger lever, and subsequently the force of the impact from this moment the rigid unit of two-armed intermediate lever and trigger lever is pivoted again until the next intermediate lever is released and the firing pin is triggered.

Die erfindungsgemäße Konstruktion erübrigt daher vor allem eine eigene Feder für die Stecheinrichtung, da deren Funktion über das Kniehebelsystem, das keinen federnden Teil beinhaltet, von der Schlagbolzenfeder übernommen werden kann. Dadurch kann außerdem eine wesentlich höhere Kraft der Stecheinrichtung zugeführt werden, als dies bei der eigenen Feder nach dem Stand der Technik erzielbar ist.The construction according to the invention therefore superfluous, especially a separate spring for the lancing device, since de Ren function via the toggle lever system, which contains no resilient part, can be taken over by the firing pin spring. This also allows a much higher force to be supplied to the lancing device than can be achieved with the own spring according to the prior art.

Zwischen dem zweiarmigen Hebel und dem Schlagbolzen können je nach Konstruktion der Waffe einer oder auch mehrere weitere Zwischenhebel ausgebildet sein. Es ist dabei erforderlich, daß in der Fangstellung des Schlagbolzens einer der Zwischenhebel in einem Ausmaß in der genannten Ebene bewegbar ist, daß der Abstandsänderung der Auflagelinie des nächstfolgenden Zwischenhebels bei der Bewegung des Kniehebelsystems entspricht, ohne daß dabei die Sperre des Schlagbolzens aufgehoben wird.Depending on the design of the weapon, one or more additional intermediate levers can be formed between the two-armed lever and the firing pin. It is necessary that in the catch position of the firing pin one of the intermediate levers can be moved to an extent in the plane mentioned that the change in distance corresponds to the contact line of the next intermediate lever during the movement of the toggle lever system without the locking of the firing pin being released.

In einer bevorzugten Ausführüng-der-erfindungsgemäßen Abzugseinrichtung ist vorgesehen, daß der zweite Anschlag für den zweiarmigen Zwischenhebel am Gehäuse der Abzugseinrichtung angeordnet ist. Es ist jedoch ebenso denkbar, auch den zweiten Anschlag am Abzugshebel selbst auszubilden.In a preferred embodiment of the trigger device according to the invention it is provided that the second stop for the two-armed intermediate lever is arranged on the housing of the trigger device. However, it is also conceivable to design the second stop on the trigger lever itself.

Eine weitere bevorzugte Ausführung der Erfindung ist dadurch gekennzeichnet, daß zumindest der zweite Anschlag für den zweiarmigen Zwischenhebel in an sich bekannter Weise einstellbar ausgebildet, und der Abstand der Achse des zweiarmigen Zwischenhebels zur Ebene veränderbar ist.A further preferred embodiment of the invention is characterized in that at least the second stop for the two-armed intermediate lever is designed to be adjustable in a manner known per se, and the distance between the axis of the two-armed intermediate lever and the plane can be changed.

Nachstehend wird nun die Erfindung in zwei Ausführungsbeispielen an Hand der Figuren der Zeichnungen daher erläutert, ohne jedoch darauf beschränkt zu sein.In the following, the invention will now be explained in two exemplary embodiments with reference to the figures of the drawings, without however being limited thereto.

Es zeigen:

  • die Figuren 1 bis 3 eine erste Ausführung der erfindungsgemäßen Abzugseinrichtung in der Flintenabzugsstellung (Fig. 1), in eingestochener Stellung (Fig. 2) und in abgezogener Stellung (Fig. 3), jeweils im Längsschnitt, und die Fig. 4 bis 6 eine zweite Ausführung in denselben drei Stellungen.
Show it:
  • Figures 1 to 3 a first embodiment of the trigger device according to the invention in the shotgun trigger position (Fig. 1), in the pierced position (Fig. 2) and in the withdrawn position (Fig. 3), each in longitudinal section, and Figs. 4 to 6 one second version in the same three positions.

Die erfindungsgemäße Abzugseinrichtung weist einen zweiarmigen Abzugshebel 1 auf, der um eine gehäusefeste Achse 6 drehbar ist. Der untere, nicht vollständig dargestellte Arm des Abzugshebels 1 bildet das Züngel 2. Am zweiten Arm 3 des Abzugshebels ist eine Achse 5 angeordnet, auf der ein zweiarmiger Zwischenhebel 4 drehbar gelagert ist. Sein Schwenkbereich wird durch zwei Anschläge 7, 8 begrenzt, von denen der erste Anschlag 7 durch eine Schrägfläche des Abzugshebels 1 an seinem zweiten Arm 3 gebildet ist.The trigger device according to the invention has a two-armed trigger lever 1, which is rotatable about an axis 6 fixed to the housing. The lower arm of the trigger 1, not shown completely, forms the tongue 2 . On the second arm 3 of the trigger, an axis 5 is arranged on which a two-armed intermediate lever 4 is rotatably mounted. Its pivoting range is limited by two stops 7, 8, of which the first stop 7 is formed by an inclined surface of the trigger lever 1 on its second arm 3.

Liegt der zweiarmige Zwischenhebel 4 am Anschlag 7 des Abzugshebels 1 an, befindet sich die Abzugseinrichtung in der Flintenabzugsstellung (Fig. 1, Fig. 4). In dieser Stellung befindet sich die Achse 5 des zweiarmigen Zwischenhebels 4 in einem Abstand b von einer Ebene A die durch die Auflagelinie 10 des nächstfolgenden Zwischenhebels 11 auf dem zweiarmigen Zwischenhebel 4 und die Achse 6 des Abzugshebels 1 verläuft. Die vom Schlagbolzen 12 auf den Zwischenhebel 11 einwirkende Kraftkomponente der Schlagbolzenfeder, deren Hauptrichtung dem Pfeil c folgt, preßt den zweiarmigen Zwischenhebel 4 fest an den Anschlag 7, sodaß eine starre Kopplung der beiden Hebel 1, 4 gegeben ist. Die Abzugsbewegung (Pfeil d) bewirkt eine gegengerichtete Bewegung des genannten zweiarmigen Zwischenhebels 4 in Richtung des Pfeiles f, sodaß der Zwischenhebel 4 sich aus seiner Sperrstellung vom nächstfolgenden Zwischenhebel 11 löst und diesen freigibt, der um die Achse 18 nach unten schwenkt. In weiterer Folge wird der Schlagbolzen 12 ebenfalls freigegeben und die in Fig. 3 und 6 gezeigte Stellung erreicht. Im Ausführungsbeispiel nach den Fig. 4 bis 6 ist zwischen dem Schlagbolzen 12 und dem Zwischenhebel 11 ein weiterer Zwischenhebel 20 angeordnet, der um eine Achse 21 ebenfalls verschwenkbar ist..If the two-armed intermediate lever 4 lies against the stop 7 of the trigger 1, the trigger device is in the shotgun trigger position (FIG. 1, FIG. 4). In this position, the axis 5 of the two-armed intermediate lever 4 is at a distance b from a plane A which runs through the support line 10 of the next intermediate lever 11 on the two-armed intermediate lever 4 and the axis 6 of the trigger lever 1. The force component of the firing pin spring acting on the intermediate lever 11 from the firing pin 12, the main direction of which follows the arrow c, presses the two-armed intermediate lever 4 firmly against the stop 7, so that there is a rigid coupling of the two levers 1, 4. The withdrawal movement (arrow d) causes a counter-movement of the two-armed intermediate lever 4 in the direction of arrow f, so that the intermediate lever 4 extends releases its locking position from the next intermediate lever 11 and releases it, which pivots down about the axis 18. Subsequently, the firing pin 12 is also released and the position shown in FIGS. 3 and 6 is reached. In the exemplary embodiment according to FIGS. 4 to 6, a further intermediate lever 20 is arranged between the firing pin 12 and the intermediate lever 11, which is also pivotable about an axis 21.

Zur Rückführung der einzelnen Teile der Abzugseinrichtung sind übliche Rückstellfedern versehen, die in den Fig. 1 bis 3 dargestellt, in den Fig.. 4 bis 6 der Übersichlichkeit halber jedoch nicht dargestellt sind. Eine Rückstellfeder 14 beaufschlagt den Abzugshebel 1, eine weitere Rückstellfeder 15 den zweiarmigen Zwischenhebel 4 und eine Rückstellfeder 17 den Zwischenhebel 11 (Fig. 1 bis 3). Die Federn 14, 15 sind in einem Bauteil 13 zusammengefaßt, der durch eine Befestigungseinrichtung 16 am Gehäuse 9 der Abzugseinrichtung fixiert ist.To return the individual parts of the trigger device, conventional return springs are provided, which are shown in FIGS. 1 to 3, but are not shown in FIGS. 4 to 6 for the sake of clarity. A return spring 14 acts on the trigger 1, a further return spring 15 on the two-armed intermediate lever 4 and a return spring 17 on the intermediate lever 11 (FIGS. 1 to 3). The springs 14, 15 are combined in a component 13 which is fixed by a fastening device 16 to the housing 9 of the trigger device.

Soll nun ein Schuß unter Verwendung der Stecheinrichtung ausgelöst werden, so wird nach Spannen des Schlagbolzens 12 der Abzugshebel 1 in Richtung des Pfeiles e bewegt. Das durch die beiden Hebel 1, 4 dargestellte Kniehebelsystem wird gestreckt, d. h. der Abstand zwischen der Achse 6 und der Auflagelinie 10 vergrößert, der Abstand b hingegen verkleinert. Die Schwenkbewegung wird durch den Anschlag 8, der durch eine am Gehäuse angeordnete Einstellschwenke 19 gebildet wird, begrenzt. In der Ausführung nach den Fig. 1 bis 3 liegt in der eingestochenen Stellung (Fig. 2) der zweiarmige Zwischenhebel 4 selbst am Anschlag 8 an, während nach der Ausführung der Fig. 4 bis 6 ein Fortsatz 22 des Abzugshebels 1 am Anschlag 8 liegt.If a shot is now to be released using the lancing device, the trigger 1 is moved in the direction of the arrow e after the firing pin 12 has been tensioned. The toggle lever system represented by the two levers 1, 4 is stretched, i. H. the distance between the axis 6 and the support line 10 increases, the distance b, on the other hand, decreases. The pivoting movement is limited by the stop 8, which is formed by an adjusting pivot 19 arranged on the housing. In the embodiment according to FIGS. 1 to 3, the two-armed intermediate lever 4 itself lies against the stop 8 in the inserted position (FIG. 2), while according to the embodiment of FIGS. 4 to 6 an extension 22 of the trigger lever 1 lies against the stop 8 .

Der Anschlag 8 könnte jedoch auch ebenfalls am Abzugshebel 1 ausgebildet sein. Während des Einstechens nähert sich die Achse 5 der Ebene A zuerst, wie erwähnt, unter der Verkleinerung des Abstandes b an, und überschreitet sie schließlich geringfügig, sodaß die Verbindungslinie B der beiden Achsen 5, 6 im Vergleich zur Flintenabzugsstellung nunmehr auf der gegenüberliegenden Seite der Ebene A liegt. Die Größe des Abstandes a zwischen der Achse 5 und der Ebene A in den eingestochenen Stellung ist durch Veränderung des Anschlages 8 einstellbar, in jedem Fall jedoch sehr gering, sodaß eine minimale Bewegung am Abzugshebel (Pfeil d) zur Rückkehr der Achse 5 und der Ebene A genügt. Die vom Schlagbolzen 12 kommende Kraftkomponente erteilt dem zweiarmigen Zwischenhebel 4 ein Drehmoment, das diesen auf den Anschlag 7 schlagen läßt, wobei die Wucht des Aufschlages sich auf den zweiten Arm 3 des Abzugshebels 1 überträgt, und beide Hebel 1, 4, die ab dem Aufschlag wieder eine starre Einheit bilden, in Richtung des Pfeiles f bewegen, wodurch der Schlagbolzen 12, wie beschrieben, freigegeben wird. Die Endstellungen zeigen wiederum die Fig. 3 und 6.However, the stop 8 could also be formed on the trigger 1. During the penetration, the axis 5 first approaches the plane A, as mentioned, by reducing the distance b, and then slightly exceeds it, so that the connecting line B of the two axes 5, 6 is now on the opposite side of the shotgun trigger position Level A lies. The size of the distance a between the axis 5 and the plane A in the inserted position can be adjusted by changing the stop 8, but in any case very small, so that there is minimal movement on the trigger (arrow d) to return the axis 5 and the plane A is enough. The force component coming from the firing pin 12 gives the two-armed intermediate lever 4 a torque which causes it to strike the stop 7, the force of the impact being transferred to the second arm 3 of the trigger lever 1, and both levers 1, 4 starting from the impact again form a rigid unit, move in the direction of arrow f, whereby the firing pin 12 is released, as described. The end positions again show FIGS. 3 and 6.

Beim Einstechen wird, wie erwähnt, der Abstand zwischen der Auflagelinie 10 und der Achse 6 des Abzugshebels 1 vergrößert. Es ist daher für einen der folgenden Zwischenhebel 11, 20 ein Spielraum erforderlich, innerhalb dessen er ohne Freigabe des Schlagbolzens 12 bewegt werden kann. Eine Sperrstufe 24 an einem der weiteren Zwischenhebel 11, bzw. 20 ist daher so hoch ausgebildet, daß der Abstand 23 zwischen dem Schlagbolzen 12 und dem jeweiligen Zwischenhebel 11, bzw. 20 verändert werden kann, ohne ihn freizugeben. Die Änderung des Abstandes 23 könnte natürlich in den Fig. 4 bis 6 auch zwischen den beiden Zwischenhebeln 11 und 20 erfolgen.When plunging, as mentioned, the distance between the support line 10 and the axis 6 of the trigger 1 is increased. A clearance is therefore required for one of the following intermediate levers 11, 20, within which it can be moved without the firing pin 12 being released. A locking step 24 on one of the further intermediate levers 11 or 20 is therefore designed so high that the distance 23 between the firing pin 12 and the respective intermediate lever 11 or 20 can be changed without releasing it. The change in the distance 23 could of course also take place in FIGS. 4 to 6 between the two intermediate levers 11 and 20.

Die erfindgungsgemäße Abzugseinrichtung bietet jedoch auch noch den weiteren Vorteil, daß der Abzugshebel 1 dank der Rückstellfeder 14, 15 aus der eingestochenen Stellung (Fig. 2, 5) ohne Schußabgabe beim Entspannen und Wiederspannen des Schlagbolzens selbsttä tig in die Flintenabzugsstellung zurückkehrt.However, the trigger device according to the invention also has the further advantage that the trigger lever 1 automatically returns to the shotgun trigger position thanks to the return spring 14, 15 from the inserted position (FIGS. 2, 5) without firing a shot when the firing pin is relaxed and reloaded.
