Preferred Features: The engaging element is a slide (61) that engages behind the trigger lever located in the action region of an engaging lug (39).

Description

Die Erfindung betrifft eine Feuerwaffe mit einem Verschluß und einem federbelasteten Verschlußfangstück.The invention relates to a Firearm with a lock and a spring-loaded Closure catching piece.

Eine solche Feuerwaffe ist aus der GB-A-15 783 bekannt, die ein Verschlußfangstück aufweist, das auf und nur bei Knopfdruck unwirksam wird.Such a firearm is known from GB-A-15 783, which a closure catch has, on and only at Pushing a button becomes ineffective.

Es wird darauf hingewiesen, daß im folgenden Lagebezeichnungen wie "oben", "vorne" usw. sich auf eine Waffe beziehen, die sich in normalem Gebrauchsanschlag befindet und deren Seelenachse (Lauf-Mittelachse) horizontal verläuft; "vorne" liegt in Schußrichtung. Eine Abzugseinrichtung besteht im einfachsten Fall aus einem Schlagstück mit Schlagfeder, das in gespanntem Zustand von einer Rast gehalten ist, die durch einen Abzug lösbar ist.It should be noted that in the following location designations such as "top," "front," etc. refer to a weapon, which is in normal use stop and whose axis of the soul (running central axis) runs horizontally; "front" is in the weft direction. A trigger device consists in the simplest case of a hammer with Striker, held in tension by a rest is, which is solvable by a trigger.

Aufgabe der Erfindung ist die Weiterbildung dieses Standes der Technik. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst und durch die Merkmale der Ansprüche 2 bis 10 weitergebildet.The object of the invention is the development of this state of the technique. This task is characterized by the characterizing Characteristics of claim 1 and solved by the features of Claims 2 to 10 further developed.

Der Gegenstand der Erfindung wird in der beigefügten, schematischen Zeichnung beispielsweise noch näher erläutert; in dieser zeigt:

The object of the invention is explained in more detail in the attached schematic drawing, for example; in this shows:
Fig. 1
a partial longitudinal section through a preferred embodiment of the trigger device of the firearm of the invention, without showing the closure member,
Fig. 2
a partial longitudinal section, but with the trigger spring in a position of increased force, and
Fig. 3
a broken cut.

In den Fig. 1 bis 3 ist ein Griffstück 3 aus abgeformtem, bevorzugt druckgegossenem Kunststoff gezeigt, dessen Oberteil von einem mit Ausnahme der Oberseite im wesentlichen allseits geschlossenen Kasten gebildet ist, an dessen Unterseite ein Griff angeformt ist. Im Kasten sitzt eine Abzugseinrichtung 5.1 to 3 is a handle 3 made of molded, preferably shown die-cast plastic whose Top of one except the top in the is formed on all sides closed box on the underside of a handle is formed. Sitting in the box a trigger device 5.

Das Griffstück 3 ist mittels zweier Querbolzen (nicht gezeigt) an der Unterseite eines Gewehrgehäuses (nicht gezeigt) angebracht, in dem ein Verschluß so beweglich angeordnet ist, daß er sich nach einem Schuß oder bei Betätigung einer Handhabe aus einer vorderen Endlage, in der das Gewehr feuerbereit ist, über das Griffstück 3 hinweg nach hinten und dann wieder nach vorne bewegt.The handle 3 is by means of two transverse bolts (not shown) at the bottom of a rifle case (not shown) attached, in which a shutter so movable is arranged to be after a shot or on actuation a handle from a front end position, in the the rifle is ready to fire, over the handle 3 away moved back and then forward again.

Der Verschluß (nicht gezeigt) weist an seiner Unterseite eine sich in seiner Längsrichtung erstreckende Auskehlung auf, deren Rückseite durch einen Unterbrechervorsprung versperrt ist.The closure (not shown) has on its underside a groove extending in its longitudinal direction on, whose back by a breaker projection is locked.

Im Griffstück 3 befindet sich ein Verschlußfangstück 71 (nur in Fig. 1 und 3 mit Bezugszeichen versehen). Ein solches Verschlußfangstück hat den Zweck, nach Abfeuern des letzten Schusses den Verschluß (nicht gezeigt) offenzuhalten, um den Schützen auf diesen Sachverhalt aufmerksam zu machen. Nach Einführen eines vollen Magazines sowie kurzem Zurückziehen und Loslassen des Ladehebels ist dann die Waffe wieder feuerbereit (der Ladehebel muß nicht, wie sonst beim Durchladen, über seine ganze Bewegungsstrecke zurückgezogen werden).In the handle 3 is a closure catch 71st (Only provided in Fig. 1 and 3 with reference numerals). One such closure catch piece has the purpose after firing the last shot the shutter (not shown) keep open to the shooter on this issue to draw attention. After inserting a full magazine as well as briefly pulling back and releasing the loading lever then the weapon ready to fire again (the loading lever does not have to as usual when passing through, over his whole Moving distance to be withdrawn).

Das Verschlußfangstück 71 weist somit an seiner Oberseite einen nach vorne weisenden Finger auf, der vom Zubringer (nicht gezeigt) des Magazins nach Entnahme der letzten Patrone um eine Strecke nach oben bewegt wird, sowie einen nach oben weisenden Fangvorsprung, der, wenn er um diese Strecke angehoben wird, in den Bewegungsweg des Verschlusses hineinragt und diesen daran hindert, sich wieder in seine vorderste Lage zu bewegen, wenn er nach Abfeuern der letzten Patrone zurückgeworfen wurde.The closure catch 71 thus has at its top a forward pointing finger from the feeder (not shown) of the magazine after removal of the last Cartridge is moved up one track, as well as one upward-pointing catch projection, when he is around this Is raised in the movement path of the lock protrudes and prevents it from getting back into his foremost position to move when he fires after the last cartridge was thrown back.

Ferner weist das Verschlußfangstück 71 eine nach unten aus dem Griffstück 3 herausstehende Verlängerung auf, die als Handhabe dient, um das Verschlußfangstück 71 auch bei entnommenem Magazin nach oben zu drücken, um den Verschluß offenhalten zu können, etwa zur Inspektion des Laufes ohne Zerlegen der Waffe.Further, the shutter catch 71 has a downwardly the handle 3 protruding extension, as Handle serves to catch the catch 71 even when removed Press the magazine up to the shutter to keep open, about to inspect the barrel without Disassemble the weapon.

Eine Feder 73 ist vorgesehen, deren vorderer Federarm verlängert wurde und auch auf das Verschlußfangstück 71 einwirkt. Diese Feder 73 ist als eine Wäscheklammerfeder ausgebildet, mit einem gewickelten Abschnitt, von dem einander etwa gegenüberliegend zwei Schenkel abstehen. Der gewickelte Abschnitt sitzt auf einem Wellenstummel des Abzugs 33 oder auf einer Büchse, die auf die Abzugsachse aufgeschoben ist, wobei ein geringes Spiel vorliegt, das die unbehinderte Bewegung des Abzuges erlaubt.A spring 73 is provided, the front spring arm was extended and also on the closure catch 71st acts. This spring 73 is as a clothespin spring formed, with a wound section, of which stand each other approximately opposite two legs. Of the wrapped section sits on a stub shaft of the Trigger 33 or on a rifle, which is on the trigger axis deferred, with a small game is present, the allowed the unimpeded movement of the trigger.

Der vordere Schenkel der Feder 73 sitzt auf einer Federaufnahme 77 auf, die am Verschlußfangstück 71 ausgebildet ist, und belastet dieses nach unten.The front leg of the spring 73 is seated on a spring receiver 77, which formed on the closure catch 71 is, and this burdened down.

Dieser Schenkel der Feder 73 ist nach vorne über das Verschlußfangstück 71 hinaus verlängert und befindet sich mit seinem Ende knapp unterhalb eines Vorsprunges 75, der am Griffstück 3 ausgebildet ist und sich über diesem Schenkelende befindet.This leg of the spring 73 is forward over the catch catch 71 extended and is located with its end just below a projection 75, the Handle 3 is formed and over this leg end located.

Wie aus Fig. 3 ersichtlich ist, ist die Federaufnahme 77 im Verschlußfangstück 71 mit zwei Ausnehmungen ausgebildet, mit einer ersten Vertiefung, deren Abstand zur horizontalen Verlängerung der unteren Fläche des Vorsprungs 75 nur gering ist, und mit einer zweiten Vertiefung, bei der dieser Abstand größer ist und mindestens der Bewegungsstrecke des Verschlußfangstücks bei seiner Funktion entspricht. Zwischen den beiden Vertiefungen befindet sich ein Abschnitt, dessen Abstand zur genannten horizontalen Verlängerung der unteren Fläche des Vorsprungs 75 größer sein muß als die Dicke des Federschenkels.As can be seen from Fig. 3, the spring retainer 77 is in Closure catch 71 formed with two recesses, with a first recess whose distance from the horizontal Extension of the lower surface of the projection 75 only slightly is, and with a second recess in which this Distance is greater and at least the movement distance of Closure catch corresponds to its function. Between the two wells is a section whose distance from said horizontal extension of bottom surface of the projection 75 must be greater than that Thickness of the spring leg.

Sitzt der Schenkel der Feder 73 in der einen Vertiefung auf (in Fig. 3 die rechte), in der ein großer Abstand zur genannten horizontalen Verlängerung vorliegt, dann erfolgt die Funktion des Verschlußfangstückes 71 unbehindert so, wie sie oben beschrieben ist.The leg of the spring 73 is seated in the one recess (in Fig. 3, the right), in which a large distance to said horizontal extension, then takes place the function of the closure catch 71 so unhindered as described above.

In manchen Einsätzen ist jedoch eine solche, vom Verschlußfangstück 71 gebildete Verschlußsperre unerwünscht, etwa weil Schlamm oder Sand in das Innere des Waffengehäuses gelangen könnte, wenn der Verschluß offenbleibt. In diesem Fall wird etwa mit Hilfe eines dünnen Schraubenziehers oder einer Messerspitze das Schenkelende der Feder 73 aus der in Fig. 3 rechten Vertiefung in die andere bzw. linke, höhere Vertiefung geschoben und dort eingelegt. Nun kann sich das Verschlußfangstück 71 nicht mehr nach oben bewegen, weil das Ende des auf diesem aufsitzenden Federschenkels den Vorsprung 75 nur knapp untergreift, so daß die Bewegung dieses Federschenkels und damit auch des Verschlußfangstücks 71 nach oben verhindert ist.In some applications, however, such is from the closure catch 71 formed closure lock undesirable, about because mud or sand in the interior of the gun barrel could get if the shutter remains open. In this Case is about using a thin screwdriver or a knife tip, the leg end of the spring 73 from the in Fig. 3 right recess in the other or left, higher Well pushed and inserted there. Now that can happen Lock catch 71 no longer move up because the end of the on this sitting spring leg the Projection 75 just under engages, so that the movement this spring leg and thus also the closure catch 71 is prevented upwards.

Die Umstellung zwischen wirksamer und unwirksamer Verschlußsperre wird durch das Hin- oder Herschieben des Federschenkels zwischen den beiden Vertiefungen bewirkt und kann z.B. vom Waffenwart der betreffenden Einheit den Bedürfnissen entsprechend vorgenommen werden. Natürlich kann eine Waffe auch mit werksseitig vorgenommener, bestimmter Einstellung ausgeliefert werden.The changeover between effective and ineffective Lock is by the back and forth of the Federschenkels between the two wells causes and can e.g. from the warden of the unit concerned to the needs be made accordingly. Of course you can a weapon also with factory made, certain Setting to be delivered.

Um die weitere Wirkungsweise der Feder zu beschreiben, sind zunächst einige allgemeine Anmerkungen zweckmäßig:To describe the further mode of action of the spring are First, some general comments appropriate:

Bekanntlich ist die Treffgenauigkeit beim Präzisionsschuß umso höher, je "weicher" der Abzug ist, d.h. je geringer die Kraft ist, die zu seiner Bewegung nach hinten aufzuwenden ist. Diese Kraft, die auch die Rückstellkraft der Abzugsfeder überwinden muß, sollte so gering sein, wie es die Handhabungs- und Funktionssicherheit der Waffe zulassen; ein unbeabsichtigtes, leichtes Berühren des Abzuges oder eine gebrauchsübliche Beschleunigung, die auf den Abzug einwirkt, wenn die Waffe etwa von einem Lastwagen fällt, dürfen den Schuß nämlich nicht auslösen, und die Abzugsfeder muß in der Lage sein, unter normalen Umgebungsbedingungen stets zuverlässig den Abzug bis in seine vorderste Lage zu bewegen.As is known, the accuracy of the precision shot the higher the "softer" the print is, i. the lower the force is to spend the movement to the rear is. This force, which is also the restoring force of the trigger spring should be as low as the Allow handling and reliability of the weapon; an unintentional, light touch of the trigger or a customary acceleration on the trigger acts when the gun falls off a truck, for example, must not trigger the shot namely, and the trigger spring must be able to under normal environmental conditions always reliably pulling the trigger down to its foremost Able to move.

Bei erschwerten Umgebungsbedingungen (starker Frost, der Fett oder Öl in der Waffe erstarren läßt, hohe Verschmutzung durch feinen Sand o.dgl.) ist jedoch bisweilen die Rückstellkraft der Abzugsfeder nicht mehr in jedem Falle ausreichend, wenn diese in erster Linie in Hinblick auf einen weichen Abzug ausgelegt wurde.In difficult environmental conditions (heavy frost, the Grease or oil in the gun freezes, high pollution by fine sand or the like) is sometimes the Restoring force of the trigger spring not in any case sufficient if these are primarily in terms of a soft trigger was designed.

Aus diesem Grunde hat man bisher die Abzugsfedern von militärischen Handfeuerwaffen so ausgelegt, daß ihre Rückstellkraft auch unter den beschriebenen, erschwerten Bedingunen noch ausreichend war, und hat dementsprechend auf die Möglichkeit verzichtet, durch eine geringe Rückstellkraft Präzisionsschüsse zu erleichtern.For this reason, one has so far the trigger springs of military Handguns designed so that their restoring force even under the described, difficult condition was still sufficient, and has accordingly on the possibility dispensed with, by a low restoring force To facilitate precision shots.

Bei der Abzugseinrichtung der Fig. 1 bis 3 besteht dagegen die Möglichkeit, je nach zu erwartenden Umgebungsbedingungen oder nach dem Ausbildungsstand des Benutzers das Abzugsgewicht bzw. die Rückstellkraft wählen zu können. By contrast, in the case of the extraction device of FIGS. 1 to 3, there exists the possibility, depending on the expected environmental conditions or the level of education of the user to select the trigger weight or the restoring force.

Die Abzugseinrichtung weist eine Abzugsfeder auf, die in den Darstellungen der Zeichnung vom Abzug verdeckt ist und deshalb nicht sichtbar ist. Sie entspricht dem Stand der Technik und ist so ausgelegt, daß der Abzug "weich" ist. Dabei kann die Rückstellkraft der Abzugsfeder deshalb besonders gering sein, weil der Abzug aus vergleichsweise leichtem Material (Kunststoff) besteht, so daß die durch Beschleunigungen hervorgerufenen Massenkräfte gering sind, denen die Rückstellkraft entgegenwirken muß.The trigger device has a trigger spring, which in the illustrations of the drawing is covered by the trigger and therefore not visible. It corresponds to the state of Technique and is designed so that the trigger is "soft". The restoring force of the trigger spring can therefore be special be low because of the deduction from comparatively lightweight material (plastic) is made, so that by Accelerations caused mass forces are low, which must counteract the restoring force.

In dem in Fig. 1 gezeigten Betriebszustand sitzt der hintere Schenkel der Feder 73 auf der Innenseite des Griffstücks 3 auf. Nun erbringt alleine die in dieser Stellungliegende Feder 73 die Rückstellkraft, die den Abzug nach vorne belastet; der Abzug ist "weich". Dieser Betriebszustand wird dann gewählt, wenn günstige Umgebungsbedingunen zu erwarten sind, oder wenn Personen mit besonderem Ausbildungsstand (Gebirgsjäger, Scharfschützen usw.) die Waffe benutzen sollen.In the operating state shown in Fig. 1, the rear sits Leg of the spring 73 on the inside of the handle 3 on. Now, only the one in this position provides Spring 73 the restoring force, which loads the trigger to the front; the trigger is "soft". This operating state is then chosen when to expect favorable environmental conditions are, or if persons with special education (Mountain Hunter, Sniper, etc.) Use the weapon should.

Über dem hinteren Abschnitt des hinteren Schenkels der Feder 73 ist an der Seitenfläche des Teils des Abzugs, der sich zum Sicherungsfortsatz 37 hin erstreckt, eine vorspringende Federabstützung 79 ausgebildet. Der hintere Schenkel der Feder 73 kann nun unter kraftspeichernder Verformung dieser Feder 73 nach oben ausgelenkt und auf die Federabstützung aufgesetzt werden. Diese Umstellung kann einfach z.B. vom Waffenwart einer Einheit etwa dadurch vorgenommen werden, daß er von oben her den Federschenkel mittels des Hakens einer Häkelnadel untergreift und anhebt.Over the back section of the rear leg of the Spring 73 is on the side surface of the part of the trigger, the extends to the backup extension 37 down, a protruding Spring support 79 formed. Rear Leg of the spring 73 can now under force-storing Deformation of this spring 73 is deflected upward and on the Spring support to be placed. This conversion can simply e.g. by the warden of a unit about by it be made that he from above the spring leg engages under the hook of a crochet hook and raises.

Nun verstärkt die Feder 73 die Rückstellkraft der (nicht gezeigten) Abzugsfeder; der Abzug wird "hart".Now the spring 73 amplifies the restoring force of the (not shown) trigger spring; the deduction becomes "hard".

Diese Stellung des Federschenkels ist in Fig. 2 gezeigt; man wird diese Stellung bei den beschriebenen ungünstigen Umgebungsbedingungen wählen, oder dann, wenn die entsprechenden Waffen an einen noch ungeübten Personenkreis ausgegeben werden, bei dem noch nicht ein sicherer Umgang mit der Waffe erwartet werden kann (z.B. Rekruten).This position of the spring leg is shown in Fig. 2; you will this position in the described unfavorable Select ambient conditions, or then, if appropriate Weapons issued to an untrained circle of people which does not yet have a safe handling the weapon can be expected (e.g., recruits).

Natürlich kann auch werksseitig eine gewünschte Einstellung vorgenommen werden.Of course, can also be a factory setting a desired setting be made.

Die beiden oben beschriebenen Einstellungen (Wirksamkeit der Verschlußsperre, auf den Abzug (33) einwirkende Rückstellkraft) können von einer eingewiesenen Person in kürzester Zeit mit einfachstem Werkzeug vorgenommen werden. Der Benutzer des Gewehres ist dazu jedoch nicht imstande, da er auch bei Betrachten des Griffstücks mit der Abzugseinrichtung keinerlei Handhabe o.dgl. finden kann, woran er etwa eigenmächtig eine Einstellung vornehmen könnte.
