  • the trigger weight mentioned can be reduced to a few 100 g, in extreme cases even to 50 g and less, by means of the piercing device explained below. With such a low trigger weight, a very slight vibration or movement of the interacting parts can be sufficient to trigger a shot. That's why it is only permitted under certain circumstances and with special safety measures and regulations, to bring about this dangerous and critical condition of the weapon.
  • this state is produced by advancing the lower arm 26 of the trigger 4, that is to say by advancing the lever 26 in the direction of the arrow in FIG. 3.
  • the trigger 4 rotates about the axis 10 so that its upper arm 27 counterclockwise towards
  • Plunger clamping piece 5 pivots.
  • the contact surface 28 of the arm 27 then presses against the roller 14, as a result of which the arm of the plunger 5 connected to the roller 14 is pivoted upward against the pressure of the spring 16.
  • the arm 27 of the trigger 4 is pivoted so far in the direction of the chuck 5, until its edge 29 engages under the roller 14 and a balance of forces between the force of the spring 16, the force of the spring 12 and the frictional force of the moving parts arises; this position can be called the dead center position. In this position, the engraver is cocked. In order to be able to carry out this tensioning of the piercer, however, it is a prerequisite that - as drawn in FIG. 3 - the safety slide 6 is in the unlocked state, as will be explained later.
  • the reduction ratio and thus the trigger weight can be varied in a simple manner by means of an adjusting screw 30, with which the amount by which the arm 27 with its edge 29 can be pivoted behind the actual dead center position of the roller 14 can be determined. If the balance of forces is destroyed by a force acting on the lever arm 26 of the trigger 4 in the direction of the arrow (FIG. 4), then it suddenly collapses under the action of the strong spring 16. The spring 16 now presses the pretensioner 5 back into its rest position (FIG. 1), the roller 14 throwing the arm 27 of the trigger 4 forward over the inclined surface 28 in the direction of the trigger rod 3. The arm 27 strikes with its surface 13 against the trigger rod 3 and knocks it out of the support latch 19 of the trigger gallery 2. The trigger gallery 2 thus pivots, as already described for the case of the stab-free firing, under the influence of the firing pin spring and gives the firing pin free.
  • the measures are to be explained which lead to the fact that, in the secured state, as mentioned, the piercer cannot be tensioned and that the tensioned piercer is relaxed when the weapon is secured.
  • the trigger device is shown with the cock under tension.
  • the safety slide 6 has at its lower end a recess 31 into which the cam 32 of the trigger 4 can enter. In the secured state (FIG. 1), this recess 31 lies below the cam 32, so that the trigger 4 or its lever 26 cannot be moved in the direction of the arrow of FIG. 3. So if the weapon is secured, ie if the safety slide 6 is in its lower position, then a "piercing" is not possible.
  • the edge 33 will slide after only a few tenths of a millimeter the surface 23 over the surface 34 of the trigger rod 3 and prevents the trigger rod 3 from being pivoted out of the catch 19 of the trigger gallery 2 by pressure or impact.
  • the inserted trigger device is already secured after a minimal displacement of the safety slide 6, so that, as is generally customary in the previously known repeating rifles, the piercer could be stabbed by manual actuation of the trigger arm 26 without a shot being triggered thereby .
  • the safety slide 6 automatically performs the stabbing in the further course of its downward movement into the secured end position, thereby that with its paragraph 35 hits the cam 32 of the trigger 4 and thereby inevitably relaxes the cocked prick.
  • the safety slide 6 jumps into one or the other end position by a suitable spring element and thereby the pulse gets to knock the trigger 4 out of its cocked position via its cam 32, this operation of the slide 6 is known per se.
  • cocking the trigger and triggering a shot by the trigger are only possible with the trigger device fully cocked and fully unlocked. If the cocked prick is to be relaxed again without triggering a shot, this can be done by actuating the safety device of the trigger device, with an - unintentional - firing of the shot being prevented even with the slightest displacement of the safety slide into the safety position.

Trigger device with a rear set trigger for small arms, in which there are arranged a trigger sear (2), pivotable in a housing (1), this trigger sear blocking the cocked firing pin in one of its pivot positions, a trigger rod (3) supporting the trigger sear in one of its pivot positions so as to hold it in its pivot position blocking the firing pin, a trigger (4) which, when operated in its trigger direction, pivots the trigger rod into its other pivot position releasing the trigger sear, and a pin cocking lever (5) which can be cocked by the trigger when it is operated counter to its trigger direction, wherein a safety element in its securing position prevents operation of the trigger in the trigger direction, characterized in that the trigger sear (2) is biased by a spring (8) into its pivot position blocking the cocked firing pin and is forced into its other pivot position by the released firing pin, in the latter pivot position restraining the pin cocking lever (5) in its released pivot position, in that when the trigger (4) is operated counter to the trigger direction it engages on the pin cocking lever (5), deflects this into the cocked position and retains it there in an unstable equilibrium, and in that the safety element (6) is a slide which, on being transferred from the released position to the securing position, disarms the cocked pin cocking lever (5), and which in its securing position blocks the trigger rod (3) against a release of the trigger sear (2) and blcoks the trigger (4) against operation also in the direction counter to the trigger direction.

Description

Die Erfindung betrifft eine Abzugseinrichtung mit Rückstecher für Handfeuerwaffen, bei der in einem Gehäuse schwenkbar ein Abzugsstollen, der in seiner einen Schwenkstellung den gespannten Schlagbolzen sperrt, eine in ihrer einen Schwenkstellung den Abzugsstollen abstützende und dabei in seiner den Schlagbolzen sperrenden Schwenkstellung haltenden Abzugsstange, ein bei Betätigung in Abzugsrichtung die Abzugsstange in ihre andere, den Abzugsstollen freigebenden Schwenkstellung schwenkenden Abzug und ein vom Abzug bei dessen Betätigung entgegen der Abzugsrichtung spannbares Stecherspannstück angeordnet sind, wobei ein Sicherungselement in seiner sichernden Stellung das Betätigen des Abzugs in Abzugsrichtung verhindert.The invention relates to a trigger device with a trigger for handguns, in which a trigger lug pivotably in a housing, which locks the cocked firing pin in its one pivot position, a trigger rod which supports the trigger gun in its one pivot position and thereby holds the trigger bar in its pivot position blocking the firing pin Actuation in the trigger direction, the trigger rod is arranged in its other pivot position, which releases the trigger studs, and a trigger tensioner which can be tensioned by the trigger when it is actuated against the trigger direction, with a securing element in its securing position preventing the trigger from being actuated in the trigger direction.

Aus Sicherheitsgründen ist die Geometrie der Abzugseinrichtungen von Handfeuerwaffen üblicherweise so ausgelegt, daß eine Kraft von mindestens 1,5 kg, vorzugsweise 2 kg, auf den Abzug ausgeübt werden muß, um einen Schuß auszulösen. Dieses hohe Abzugsgewicht führt aber, insbesondere bei weniger geübten Schützen, vielfach zu einem Verreißen des Schusses. Abhilfe schaffen hier die sogenannten Stechereinrichtungen, wobei es sich um eine in die Abzugsrichtung eingebaute Zusatzvorrichtung handelt, mit der das Abzugsgewicht auf bis ca. hundert Gramm, reduziert werden kann. Schon eine sehr geringe Erschütterung oder Bewegung der Waffe genügt dann aber, um einen Schuß auszulösen. Deshalb ist es auch nur unter bestimmten Umständen und unter Beobachtung besonderer Sicherheitsmaßnahmen und -vorschriften erlaubt, diesen gefährlichen und kritischen Zustand der Waffe herbeizuführen. So ist es beispielsweise vorgeschrieben, daß erst im Anschlag kurz vor Abgabe des Schusses der Stecher gespannt werden darf, d.h. , erst dann, wenn die Waffe bereits auf das zu beschießende Ziel gerichtet ist. Weiterhin ist Vorschrift, daß der Stecher sofort wieder entspannt werden muß, wenn der geplante Schuß aus irgendwelchen Gründen nicht abgegeben werden konnte.For safety reasons, the geometry of the trigger devices of small arms is usually designed such that a force of at least 1.5 kg, preferably 2 kg, must be exerted on the trigger to trigger a shot. However, this high trigger weight often leads to the shot getting torn, especially with less experienced shooters. This is remedied by the so-called pricking devices, which is an additional device installed in the direction of the trigger, with which the trigger weight can be reduced to up to approximately one hundred grams. Even a very slight vibration or movement of the weapon is then sufficient to trigger a shot. Therefore, it is only permitted under certain circumstances and under observation of special safety measures and regulations to bring about this dangerous and critical condition of the weapon. For example, it is stipulated that the trigger should only be tensioned shortly before the shot is fired, i.e. , only when the weapon is already aimed at the target to be shot. It is also a requirement that the piercer must be released immediately if the planned shot could not be fired for any reason.

Bei der eingangs erwähnten Abzugseinrichtung mit Rückstecher, wie sie in der DE-PS-22 53 199 offenbart ist, sind deshalb Maßnahmen getroffen, die dafür Sorge tragen, daß bei geöffneter Kammer oder entspanntem Schloß der Stecher nicht gespannt werden kann und daß beim öffnen des Verschlusses sich der gespannte Stecher selbsttätig entspannt. Ännliche Sicherheitsmaßnahmen sind bei einer konstruktiv etwas anders gestalteten Abzugseinrichtung nach der DE-PS-29 33 107 getroffen; auch hier kann der Stecher nur bei gespanntem Schloß und geschlossener Kammer gespannt werden und wird beim Öffnen des Verschlusses selbsttätig entspannt.In the trigger device with backstitch mentioned at the outset, as disclosed in DE-PS-22 53 199, measures are therefore taken to ensure that when the chamber is open or the lock is relaxed, the setter cannot be tensioned and that when the The tensioned setter automatically relaxes. Similar security measures are taken with a structurally somewhat different extraction device according to DE-PS-29 33 107; here too, the set can only be tightened when the lock and chamber are closed and is automatically released when the lock is opened.

Aufgabe der vorliegenden Erfindung ist es nun, die Sicherheit derartiger Abzugseinrichtungen noch weiter zu erhöhen, nämlich ein ungewolltes Auslösen des Schusses durch den Stecher auch dann zu verhindern, wenn der Schütze gegen die Vorschriften handelt und bereits längere Zeit vor dem Schuß, nämlich bei gesicherter Abzugseinrichtung, den Stecher spannen will und/oder bei Nichtabgabe des beabsichtigten Schusses vergißt, den Stecher durch Öffnen des Verschlusses zu entspannen. Die Lösung dieser Aufgabe erfolgt dadurch, daß der Abzugsstollen in seine den gespannten Schlagbolzen sperrende Schwenkstellung durch eine Feder belastet und in seine andere Schwenkstellung durch den ungespannten Schlagbolzen gezwungen ist, wobei er in der letzteren Schwenkstellung das Stecherspannstuck in dessen ungespannter Schwenkstellung arretiert, daß der Abzug bei seiner Betätigung entgegen der Abzugsrichtung am Stecherspannstück angreift, dieses in die Spannstellung verschwenkt und in dieser in einem labilen Gleichgewicht festhält, und daß das Sicherungselement ein Schieber ist, der bei Überführung von der entsicherten in die sichernde Stellung das gespannte Stecherspannstück entspannt und der in seiner sichernden Stellung die Abzugsstange gegen eine Freigabe des Abzugsstollens und den Abzug gegen eine Betätigung auch in Richtung gegen die Abzugsrichtung sperrt.The object of the present invention is now to further increase the safety of such trigger devices, namely to prevent the trigger from being triggered unintentionally even when the shooter is acting against the regulations and has been there for a long time before the shot, namely when the trigger device is secured , the piercer wants to cock and / or forgets to release the piercer by opening the breech if the intended shot is not fired. This object is achieved in that the trigger gallery is loaded into its pivot position blocking the strained firing pin by a spring and is forced into its other pivot position by the untensioned firing pin, and in the latter pivot position it locks the plunger clamp in its untensioned pivot position that the trigger attacks when actuating against the trigger direction on the plunger clamping piece, pivots it into the clamping position and holds it in an unstable equilibrium, and that the securing element is a slide which relaxes the tensioned plunger clamping piece during the transfer from the unlocked to the securing position and which in its securing position locks the trigger rod against a release of the trigger gallery and the trigger against actuation also in the direction of the trigger direction.

Bei der erfindungsgemäßen Abzugseinrichtung ist es also nicht möglich, den Stecher zu spannen, solange die Waffe gesichert ist. Der Schütze wird damit gezwungen, das Spannen des Stechers erst nach dem Entsichern der Waffe, also wenn diese sich bereits im Anschlag befindet, vorzunehmen. Wird der beabsichtigte Schuß aus irgendwelchen Gründen nicht abgegeben, dann erfolgt durch das Sichern der Waffe ein selbsttätiges Entspannen des Stechers, so daß sich der bisher übliche zusätzliche Vorgang, nämlich das Öffnen des Verschlusses oder das separate manuelle Entspannen des Stechers nach dem Sichern erübigt.In the trigger device according to the invention, it is therefore not possible to cock the set as long as the weapon is secured. The shooter is thus forced to tighten the trigger only after the weapon has been unlocked, i.e. when it is already in the firing position. If the intended shot is not fired for any reason, the gun is automatically released from the safety by securing the weapon, so that the previously usual additional process, namely the opening of the breech or the separate manual relaxation of the stick after the safety is avoided.

Zunächst werden anhand der Fig. 1 und 2 der Aufbau und die Funktionsweise des Abzugs und der Sicherung beschrieben, und zwar ohne Berücksichtigung der - ungespannten - Stechereinrichtung.First of all, the structure and the mode of operation of the trigger and the fuse are described with reference to FIGS. 1 and 2, without taking into account the - unstressed - pricking device.

Gemäß Fig. 1 sind in einem Abzugsgehäuse 1 ein Abzugsstollen 2, eine Abzugsstange 3 und ein Abzug 4 jeweils drehbar gelagert. Mit 5 ist ein im Abzugsgehäuse 1 ebenfalls drehbar gelagertes Stecherspannstücke 5 bezeichnet. Weiterhin ist im Abzugsgehäuse 1 ein Sicherungsschiebar 6 gleitbar gelagert.1, a trigger gallery 2, a trigger rod 3 and a trigger 4 are each rotatably mounted in a trigger housing 1. 5 with a plunger clamping piece 5 is also rotatably mounted in the trigger housing 1. Furthermore, a safety slide 6 is slidably mounted in the trigger housing 1.

Der Abzugsstollen 2 ist um eine Achse 7 begrenzt drehbar und wird durch eine Feder 8 in eine obere Stellung belastet, die seine Kopplung mit einer Schlagbolzenmutter 9 sicherstellt. Die Abzugsstange 3 ist um eine Achse 10 drehbar und wird von einem federbelasteten Bolzen 11 in Richtung auf den Abzugsstollen 2 hin belastet, Der Abzug 4 ist ebenfalls drehbar auf dieser Achse 10 gelagert und wird durch eine Feder 12 mit seiner Anlagefläche 13 gegen die Abzugsstange 3 gedrückt. Das StecherSpannstück 5 ist doppelarmig ausgebildet und weist auf den dem Abzug 4 zugewandten Arm eine Spannrolle 14 und eine Justierschraube 15 auf, während an dem anderen Arm eine Feder 16 angreift. Die Justierschraube 15 dient zum Ausgleich von fertigungsbedingten Toleranzen und erlaubt die optimale Positionierung der Spannrolle 14 gegenüber dem oberen Arm 17 des Abzugs 14. Der Sicherungsschiebbar 6 weist eine untere Sicherungsstellung (Fig. 1) und eine obere entsicherte Stellung (Fig.2) auf,The take-off lug 2 can be rotated to a limited extent about an axis 7 and is loaded into an upper position by a spring 8, which ensures its coupling with a firing pin nut 9. The trigger rod 3 is rotatable about an axis 10 and is loaded by a spring-loaded pin 11 in the direction of the trigger gallery 2. The trigger 4 is also rotatably mounted on this axis 10 and is supported by a spring 12 with its contact surface 13 against the trigger rod 3 pressed. The engraver clamping piece 5 is double-armed and has a tensioning roller 14 and an adjusting screw 15 on the arm facing the trigger 4, while a spring 16 acts on the other arm. The adjusting screw 15 is used to compensate for manufacturing-related tolerances and allows the tensioning roller 14 to be optimally positioned with respect to the upper arm 17 of the trigger 14. The safety slide 6 has a lower securing position (FIG. 1) and an upper unlocked position (FIG. 2),

Im gespannten Zustand der Waffe tritt die Schlagbolzenmutter 9 hinter einen Haken 18 des Abzugsstollens 2. Dabei kann der Abzugsstollen 2 der von der Schlagbolzenmutter 9 auf ihn ausgeübten Kraft nicht ausweichen, d. h. nicht nach unten schwenken, weil er sich mit seiner Fläche 19 gegen die Fläche 20 der Abzugsstange 3 abstützt. Wie aus der Zeichnung ersichtlich ist, weist dabei der Abzugsstollen 2 zwei Nocken 21 und 22 auf, wobei die Höhendifferenz zwischen unterem Nocken 21 und oberem Nocken 22 den Rasteneintritt bestimmt, das heißt, den Grad der Überschneidung zwischen den Stützflächen 19 und 20. Die Stirnflächen der Nocken 21 und 22 sind zweckmäßigerweise parallel zur Bewegungsrichtung des Sicherungsschiebers 6 ausgebildet. Der Abstand zwischen der Fläche 23 des Sicherungsschiebers 6 und dem oberen Nocken 22 des Abzugsstollens 2 muß geringer sein als der Abstand zwischen der Fläche 23 und dem unteren Nocken 21 des Abzugsstollens 2; in der Praxis liegt der Abstandsunterschied zweckmäßigerweise zwischen 0,2 und 0,4 mm. Die Breite des Kopfes 24 der Abzugsstange 3 muß dem Abstand zwischen Nocken 21 und Fläche 23 entsprechen. Wie die Stirnfläche der Nocken 21 und 22 des Abzugsstollens 2 parallel zur Fläche 23 des Sicherungsschiebers 3 soll auch der Kopf 24 der Abzugsstange 3 dazu parallele Flächen aufweisen. Dies ermöglicht eine wirtschaftliche Fertigung sehr enger Toleranzen mittels einfacher Schleifvorgänge. Die Wahl einfacher, leicht zu fertigender und zu kontrollierender Formen im Bereich der Abzugsrasten darstellenden Bauelemente garantiert ein sehr hohes Maß an Sicherheit, weil der Abzugsstollen 2 im gesicherten Zustand wegen der vorgeschriebenen Abstandsdifferenz zwischen Nocken 22 und Fläche 23 einerseits und zwischen Nocken 21 und Fläche 23 andererseits auch dann nicht ungewollt freigegeben werden kann, wenn die Stützflächen 19 und 20 durch unsachgemäße Behandlung beschädigt oder abgenutzt sein sollten.In the cocked state of the weapon, the firing pin nut 9 passes behind a hook 18 of the trigger stud 2. The trigger stud 2 cannot escape the force exerted on it by the firing pin nut 9, i. H. do not swivel downward because its surface 19 is supported against the surface 20 of the trigger rod 3. As can be seen from the drawing, the take-off gallery 2 has two cams 21 and 22, the height difference between the lower cam 21 and the upper cam 22 determining the catch entry, that is to say the degree of overlap between the support surfaces 19 and 20. The end faces the cams 21 and 22 are expediently formed parallel to the direction of movement of the safety slide 6. The distance between the surface 23 of the safety slide 6 and the upper cam 22 of the trigger lug 2 must be less than the distance between the surface 23 and the lower cam 21 of the trigger lug 2; in practice the difference in distance is advantageously between 0.2 and 0.4 mm. The width of the head 24 of the trigger rod 3 must correspond to the distance between the cam 21 and the surface 23. Like the end face of the cams 21 and 22 of the trigger block 2 parallel to the surface 23 of the safety slide 3, the head 24 of the trigger rod 3 should also have parallel surfaces. This enables economical manufacturing of very tight tolerances by means of simple grinding processes. The choice of simple, easy-to-manufacture and controlable components in the area of the trigger catches guarantees a very high level of security because the trigger gallery 2 in the secured state due to the prescribed difference in distance between cams 22 and surface 23 on the one hand and between cams 21 and surface 23 on the other hand, cannot be released unintentionally even if the support surfaces 19 and 20 are damaged or worn out by improper handling.

In der in Fig. 1 dargestellten gesicherten Lage kann kein Schuß abgegeben werden, weil die Anlagefläche 23 des Sicherungsschiebers 6 eine Verschwenkung der Abzugsstange im Uhrzeigersinn verhindert und die Abzugsstange 3 damit den Abzugsstollen 2 nicht freigeben kann, deren Haken 18 also die Schlagbolzenmutter 9 festhält. Zum Abgeben eines Schusses muß deshalb zunächst der Sicherungsschieber 6 in Pfeilrichtung (Fig. 2) nach oben verschoben werden, mit der Folge, daß der Kopf 24 nicht mehr an der Fläche 23 anliegt und die Ausnehmung 25 des Sicherungsschiebers 6 es erlaubt, daß die Abzugsstange 3 beim Betätigen des Abzugs 4 eine begrenzte Bewegung im Uhrzeiger sinn gegen den Druck des federbelasteten Bolzens 11 aus der Stützrast des Abzugsstollens 2 ausführt. Der Abzugsstollen 2 kann dann unter der Wirkung der von der Schlagbolzenfeder über die Schlagbolzenmutter 9 auf ihn ausgeübten Kraft nach unten gegen den Druck der Feder 8 wegschwenken und den Schlagbolzen unter der Wirkung der Schlagbolzenfeder nach vorne schnellen lassen (Fig. 6).In the secured position shown in FIG. 1, no shot can be fired because the contact surface 23 of the safety slide 6 prevents the trigger rod from pivoting clockwise and the trigger rod 3 cannot therefore release the trigger stud 2, the hook 18 of which therefore holds the firing pin nut 9. To fire a shot, the safety slide 6 must therefore first be moved upward in the direction of the arrow (FIG. 2), with the result that the head 24 no longer lies against the surface 23 and the recess 25 of the safety slide 6 allows the trigger rod 3 when operating the trigger 4 a limited movement clockwise sense against the pressure of the spring-loaded pin 11 from the support latch of the trigger gallery 2 executes. The trigger lug 2 can then swing away under the action of the force exerted on it by the firing pin spring via the firing pin nut 9 against the pressure of the spring 8 and allow the firing pin to fly forward under the action of the firing pin spring (FIG. 6).

Das Verschwenken der Abzugsstange 3 aus der Stützrast des Abzugsstollens 2 zum Zweck der Schußabgabe erfolgt durch Druck auf den unteren Arm 26 des Abzuges 4. Aus Sicherheitsgründen ist die Geometrie der Abzugsstützrasten so ausgelegt, daß eine Kraft von mindestens 1,5 kg, vorzugsweise 2 kg, auf den unteren Arm 26 des Abzugs 4 ausgeübt werden muß, um einen Schuß auszulösenThe trigger rod 3 is pivoted out of the support latch of the trigger block 2 for the purpose of firing the shot by pressure on the lower arm 26 of the trigger 4. For safety reasons, the geometry of the trigger support latches is designed such that a force of at least 1.5 kg, preferably 2 kg , must be applied to the lower arm 26 of the trigger 4 to trigger a shot

Mittels der nachfolgend erläuterten Stechereinrichtung kann das erwähnte Abzugsgewicht auf einige 100 g, im Extremfall sogar auf 50 g und weniger, reduziert werden. Bei einem derart niedrigen Abzugsgewicht kann schon eine sehr geringe Erschütterung oder Bewegung der zusammenwirkenden Teile genügen, um einen Schuß auszulösen. Deshalb ist es auch nur unter bestimmten Umständen bei Beachtung besonderer Sicherheitsmaßnahmen und -vorschriften erlaubt, diesen gefährlichen und kritischen Zustand der Waffe herbeizuführen. Bei der erfindungsgemäßen Abzugseinrichtung wird dieser Zustand durch Vordrücken des unteren Armes 26 des Abzuges 4 hergestellt, also durch Vordrücken des Hebels 26 in Richtung des Pfeils von Fig. 3. Der Abzug 4 dreht sich dabei um die Achse 10, so daß sein oberer Arm 27 gegen den Uhrzeigersinn in Richtung zumThe trigger weight mentioned can be reduced to a few 100 g, in extreme cases even to 50 g and less, by means of the piercing device explained below. With such a low trigger weight, a very slight vibration or movement of the interacting parts can be sufficient to trigger a shot. That's why it is only permitted under certain circumstances and with special safety measures and regulations, to bring about this dangerous and critical condition of the weapon. In the trigger device according to the invention, this state is produced by advancing the lower arm 26 of the trigger 4, that is to say by advancing the lever 26 in the direction of the arrow in FIG. 3. The trigger 4 rotates about the axis 10 so that its upper arm 27 counterclockwise towards

Stecherspannstück 5 hin schwenkt. Die Anlagefläche 28 des Armes 27 drückt dann gegen die Rolle, 14, wodurch der mit der Rolle 14 verbundene Arm des Stecherspannstucks 5 gegen den Druck der Feder 16 nach oben verschwenkt wird. Der Arm 27 des Abzuges 4 wird dabei soweit in Richtung Stecherspannstück 5 weitergeschwenkt, bis seine Kante 29 unter die Rolle 14 greift und ein Kräftegleichgewicht zwischen der Kraft der Feder 16, der Kraft der Feder 12 und der Reibkraft der bewegten Teile entsteht; diese Lage kann als Totpunktlage bezeichnet werden. In dieser Lage ist also der Stecher gespannt. Um dieses Spannen des Stechers durchführen zu können, ist aber Voraussetzung, daß sich - wie in Fig. 3 gezeichnet - der Sicherungsschieber 6 im entsicherten Zustand befindet, wie später noch erläutert werden wird.Plunger clamping piece 5 pivots. The contact surface 28 of the arm 27 then presses against the roller 14, as a result of which the arm of the plunger 5 connected to the roller 14 is pivoted upward against the pressure of the spring 16. The arm 27 of the trigger 4 is pivoted so far in the direction of the chuck 5, until its edge 29 engages under the roller 14 and a balance of forces between the force of the spring 16, the force of the spring 12 and the frictional force of the moving parts arises; this position can be called the dead center position. In this position, the engraver is cocked. In order to be able to carry out this tensioning of the piercer, however, it is a prerequisite that - as drawn in FIG. 3 - the safety slide 6 is in the unlocked state, as will be explained later.

Zum Auslösen eines Schusses mittels des Stechers ist es nun erforderlich, das erwähnte Kräftegleichgewicht aufzuheben, was dadurch geschieht, daß auf den unteren Arm 26 des Abzugs 4 mit einer bestimmten Kraft in Gegenrichtung zum Stecherspannen eingewirkt wird. Aufgrund der besonderen Kräfteverhältnisse, die sich bei einer in der Totpunktlage abgestützten Rolle ergeben, genügt dabei eine im Verhältnis zu der von der Feder 16 auf die Kante 29 des Armes 27 erzeugten großen Stützkraft sehr geringe Auslenkkraft, um das Kräftegleichgewicht aufzuheben, d.h. es liegt ein großes Untersetzungsverhältnis vor, mittels dessen sich das Abdrückgewicht auf 100 g und weniger reduzieren läßt. Das Untersetzungsverhältnis und damit das Abzugsgewicht kann auf einfache Weise mittels einer Stellschraube 30 variiert werden, mit der sich das Maß festlegen läßt, um welches der Arm 27 mit seiner Kante 29 hinter die eigentliche Totpunktlage der Rolle 14 geschwenkt werden kann. Wird das Kräftegleichgewicht durch eine auf den Hebelarm 26 des Abzugs 4 in Pfeilrichtung (Fig.4) wirkende Kraft zerstört, dann bricht es unter der Wirkung der starken Feder 16 schlagartig zusammen. Die Feder 16 drückt das Stecherspannstück 5 jetzt in seine Ruhelage (Fig. 1) zurück, wobei die Rolle 14 den Arm 27 des Abzuges 4 über die schräge Fläche 28 nach vorne in Richtung auf die Abzugsstange 3 schleudert. Der Arm 27 prallt mit seiner Fläche 13 gegen die Abzugsstange 3 und schlägt diese aus der Stützrast 19 des Abzugsstollens 2. Der Abzugsstollen 2 schwenkt somit, wie bereits für den Fall der stecherlosen Schußauslösung beschrieben, unter dem Einfluß der Schlagbolzenfeder nach unten und gibt den Schlagbolzen frei.To trigger a shot by means of the piercer, it is now necessary to break the aforementioned balance of forces, which is done by acting on the lower arm 26 of the trigger 4 with a certain force in the opposite direction to the piercing clamping. Due to the special force relationships that result in a roller supported in the dead center position, a very small deflection force in relation to the large supporting force generated by the spring 16 on the edge 29 of the arm 27 is sufficient to break the balance of forces, i.e. there is a large reduction ratio by means of which the trigger weight can be reduced to 100 g and less. The reduction ratio and thus the trigger weight can be varied in a simple manner by means of an adjusting screw 30, with which the amount by which the arm 27 with its edge 29 can be pivoted behind the actual dead center position of the roller 14 can be determined. If the balance of forces is destroyed by a force acting on the lever arm 26 of the trigger 4 in the direction of the arrow (FIG. 4), then it suddenly collapses under the action of the strong spring 16. The spring 16 now presses the pretensioner 5 back into its rest position (FIG. 1), the roller 14 throwing the arm 27 of the trigger 4 forward over the inclined surface 28 in the direction of the trigger rod 3. The arm 27 strikes with its surface 13 against the trigger rod 3 and knocks it out of the support latch 19 of the trigger gallery 2. The trigger gallery 2 thus pivots, as already described for the case of the stab-free firing, under the influence of the firing pin spring and gives the firing pin free.

Anhand von Fig. 5 sollen nun die Maßnahmen erläutert werden, die dazu führen, daß im gesicherten Zustand wie erwähnt der Stecher nicht gespannt werden kann, und daß der gespannte Stecher beim Sichern der Waffe entspannt wird. Dabei ist in Fig. 5 nochmals, wie schon in Fig. 3, die Abzugseinrichtung bei gespanntem Stecher dargestellt, Ersichtlicherweise besitzt der Sicherungsschiebbar 6 an seinem unteren Ende eine Ausnehmung 31, in die der Nocken 32 des Abzugs 4 eintreten kann. Im gesicherten Zustand (Fig. 1) liegt diese Ausnehmung 31 unterhalb des Nockens 32, so daß der Abzug 4 bzw. dessen Hebel 26 nicht in Richtung des Pfeils von Fig. 3 verschoben werden kann. Ist also die Waffe gesichert, d. h., befindet sich der Sicherungsschiebbar 6 in seiner unteren Position, dann ist ein "Einstechen" nicht möglich. Wird nun aber bei ungesicheter Waffe (Sicherungsschiebbar 6) in seiner oberen Position und gespanntem Stecher, die Waffe gesichert, also der Sicherungsschieber 6 nach unten geschoben (Fig. 5), dann schiebt sich schon nach einem Weg von wenigen Zehnteln eines Millimeters die Kante 33 der Fläche 23 über die Fläche 34 der Abzugsstange 3 und verhindert, daß die Abzugsstange 3 durch Druck oder Schlag aus der Rast 19 des Abzugsstollen 2 herausgeschwenkt werden kann. Das bedeutet, daß die eingestochene Abzugseinrichtung schon nach einer minimalen Verschiebung des Sicherungsschiebers 6 gesichert ist, so daß der Stecher nun, wie bei den bisher bekannten Repetierbüchsen allgemein üblich, durch manuelle Betätigung des Abzugsarmes 26 entstochen werden könnte, ohne daß dadurch ein Schuß ausgelöst wird. Um nun aber zu verhindern, daß dieses äußerst wichtige Entstechen durch Betätigen des Abzugarmes 26 aus Vergeßlichkeit oder Leichtsinn unterlassen wird, ist erfindungsgemäß vorgesehen, daß der Sicherungsschieber 6 im weiteren Verlauf seiner Bewegung nach unten in die gesicherte Endstellung selbsttätig das Entstechen vornimmt, und zwar dadurch, daß der mit seinem Absatz 35 auf den Nocken 32 des Abzugs 4 trifft und dadurch den gespannten Stecher zwangsläufig entspannt. Beim Sichern der Waffe wird also zunächst sichergestellt, daß das gespannte Stecherspannstück nicht mehr in der Lage ist, einen Schuß auszulösen, worauf dann während des weiteren Bewegungsweges des Schiebers 6 eine selbsttätige Entspannung des Stecherspannstücks 5 erfolgt, und zwar ohne daß der Schütze den Stecher manuell durch Verschieben des Abzugs 4 entstechen müßte. In diesem Zusammenhang ist darauf hinzuweisen, daß der Sicherungsschieber 6 durch ein geeignetes Federelement in die eine oder andere Endlage springt und dadurch den Impuls bekommt, um den Abzug 4 über seinen Nocken 32 aus seiner gespannten Stellung herauszuschlagen, wobei diese Funktionsweise des Schiebers 6 an sich bekannt ist.5, the measures are to be explained which lead to the fact that, in the secured state, as mentioned, the piercer cannot be tensioned and that the tensioned piercer is relaxed when the weapon is secured. 5, as already shown in FIG. 3, the trigger device is shown with the cock under tension. Obviously, the safety slide 6 has at its lower end a recess 31 into which the cam 32 of the trigger 4 can enter. In the secured state (FIG. 1), this recess 31 lies below the cam 32, so that the trigger 4 or its lever 26 cannot be moved in the direction of the arrow of FIG. 3. So if the weapon is secured, ie if the safety slide 6 is in its lower position, then a "piercing" is not possible. If, however, the weapon is secured with the weapon unsecured (safety slide 6) in its upper position and cocked prick, i.e. the safety slide 6 is pushed down (FIG. 5), the edge 33 will slide after only a few tenths of a millimeter the surface 23 over the surface 34 of the trigger rod 3 and prevents the trigger rod 3 from being pivoted out of the catch 19 of the trigger gallery 2 by pressure or impact. This means that the inserted trigger device is already secured after a minimal displacement of the safety slide 6, so that, as is generally customary in the previously known repeating rifles, the piercer could be stabbed by manual actuation of the trigger arm 26 without a shot being triggered thereby . However, in order to prevent this extremely important stabbing by omitting forgetfulness or recklessness by actuating the trigger arm 26, it is provided according to the invention that the safety slide 6 automatically performs the stabbing in the further course of its downward movement into the secured end position, thereby that with its paragraph 35 hits the cam 32 of the trigger 4 and thereby inevitably relaxes the cocked prick. When securing the weapon, it is first ensured that the cocked cocking clamp is no longer able to trigger a shot, whereupon during the further movement of the slide 6 there is an automatic relaxation of the cocking cock 5, without the shooter manually triggering the cock would have to stab by moving the trigger 4. In this context, it should be noted that the safety slide 6 jumps into one or the other end position by a suitable spring element and thereby the pulse gets to knock the trigger 4 out of its cocked position via its cam 32, this operation of the slide 6 is known per se.

Fig. 6 schließlich zeigt die Abzugseinrichtung im abgeschossenen Zustand der Waffe. Der Abzugsstollen 2 ist durch die Unterkante der Schlagbolzenmutter 9 gegen den Druck der Feder 8 nach unten geschwenkt, so daß seine Unterkante 36 mit geringem Zwischenraum parallel zur Oberkante 37 des Stecherspannstücks 5 liegt. Bedingt durch diesen geringen Abstand ist es nicht möglich, den Stecher durch Verschwenken des Abzugs 4 zu spannen, da der dem Abzug 4 zugewandte, mit der Rolle 14 versehene Arm des Stecherspannstücks 5 durch die Unterkante 36 des Abzugsstollens 2 an einer Aufwärtsbewegung gehindert ist.6 finally shows the trigger device in the fired state of the weapon. The take-off lug 2 is pivoted downward by the lower edge of the firing pin nut 9 against the pressure of the spring 8, so that its lower edge 36 lies parallel to the upper edge 37 of the plug clamping piece 5 with a small gap. Due to this small distance, it is not possible to tension the piercer by pivoting the trigger 4, since the arm 4 of the piercing clamping element 5 facing the trigger 4 and provided with the roller 14 is prevented from moving upwards by the lower edge 36 of the trigger stud 2.

Zusammenfassend ist also zu sagen: Ein Spannen des Stechers und ein Auslösen eines Schusses durch den Stecher sind nur bei gespannter und völlig entsicherter Abzugseinrichtung möglich. Soll der gespannte Stecher ohne Auslösen eines Schusses wieder entspannt werden, dann kann dies durch Betätigung der Sicherung der Abzugseinrichtung erfolgen, wobei bereits bei geringster Verschiebung des Sicherungsschiebers in die Sicherungsposition eine - ungewollte - Schußabgabe verhindert wird.In summary, it can be said that cocking the trigger and triggering a shot by the trigger are only possible with the trigger device fully cocked and fully unlocked. If the cocked prick is to be relaxed again without triggering a shot, this can be done by actuating the safety device of the trigger device, with an - unintentional - firing of the shot being prevented even with the slightest displacement of the safety slide into the safety position.
