Für eine derartige Minimierung der Gefahren, stellt die
Eine weitere Ausbildung eines Verschlusses ist der
Die vorliegende Erfindung zielt nun darauf ab, eine Vorrichtung zur Verfügung zu stellen, mit welcher ein unbeabsichtigtes Öffnen des Kammerstängels bzw. eines Verschlusses einer Schusswaffe, insbesondere eines Geradezug-Repetiergewehrs verhindert ist und zielt weiterhin darauf ab, bestehende Verschlüsse dahingehend weiter zu bilden, dass diese einerseits konstruktiv vereinfacht werden und andererseits ein hohes Maß an Sicherheit gewähren.The present invention now aims to provide a device with which an unintentional opening of the chamber stem or a closure of a firearm, in particular a straight-line repeating rifle is prevented and further aims to further form existing closures that On the one hand, these are structurally simplified and, on the other hand, they guarantee a high degree of security.
Zur Lösung dieser Aufgabe ist der erfindungsgemäße Verschluss im Wesentlichen dadurch gekennzeichnet, dass das Kettenglied als gerades Kettenglied ausgebildet ist, dass das Kettenglied in einer wenigstens einen Drittelkreis überdeckenden, seitlichen Ausnehmung des Kammerstängels angelenkt ist und dass in einer Schließposition des Kammerstängels die Längsachse des Kettenglieds im Wesentlichen mit der Längsachse des Verschlusses zusammenfällt. Indem das Kettenglied als gerades Kettenglied ausgebildet ist, welches in einer wenigstens einen Drittelkreis überdeckenden seitlichen Ausnehmung des Kammerstängels angelenkt ist, ist während einer Öffnungs- und Schließbewegung des Kammerstängels, d.h. während eines Öffnen und Schließens des Verschlusses eine freie Verschwenkbarkeit ohne irgendein Anschlagen oder Verhaken des Kettengliedes im Inneren des Kammerstängels sichergestellt und indem weiterhin in der Schließposition des Kammerstängels die Anlenkachse des Kettengliedes an dem Kammerstängel im Wesentlichen mit der Längsachse des Verschlusses zusammenfällt, wird sichergestellt, dass ein unbeabsichtigtes Öffnen des Kammerstängels durch eine in axialer Richtung wirkende Kraft, beispielsweise durch einen während eines Schusses ausgeübten Stoß nicht möglich ist.

Kreissegmentes Gebrauch gemacht und jegliche Spitzen oder Ecken bzw. eckig ausgebildete Fortsätze des Kammerstängels in dem während der Öffnungs- und Schließbewegung besonders belasteten Bereich desselben vermieden. Durch eine derartige Konstruktion wird eine einfache und sichere Verschwenkung des Kammerstängels von seiner Öffnungs- in seine Schließposition und umgekehrt gewährleistet und gleichzeitig sichergestellt, dass selbst bei Einwirken von großen axialen Kräften auf den Kammerstängel dieser nicht unbeabsichtigt geöffnet bzw. durch ein Aus- oder Abschlagen von Fortsätzen bzw. Kanten funktionsunfähig gemacht wird bzw. die Präzision der Funktion stark beeinträchtigt wird.In order to withstand excessive wear, in particular a knocking or tearing out of the highly stressed by the articulation of the chain link portion of the chamber stem, the closure is designed so that the at least one third circle overlapping, lateral recess of the chamber stem in a in Closing position of the chamber stem is formed substantially in the direction of the locking bar projecting substantially circular segment-shaped extension. In this embodiment of the invention deviating from known from the prior art constructions of the chamber stem of the reasons of stability particularly advantageous form of a circle or circle segment made use of any tips or corners or angularly formed extensions of the chamber stem in the during the opening and Closing movement particularly loaded area of the same avoided. Such a design ensures a simple and safe pivoting of the chamber stem from its opening into its closed position and vice versa and at the same time ensures that even with the action of large axial forces on the chamber stem this not accidentally opened or by a training or knocking of Fortsätzen or edges is rendered inoperable or the precision of the function is greatly impaired.
Um ein unbeabsichtigtes bzw. zufälliges Öffnen des Verschlusses und insbesondere eine Verschiebung der Verschlusshülse in Bezug auf den Verschlusskasten mit Sicherheit zu vermeiden, ist gemäß einer bevorzugten Weiterbildung der Erfindung der Verschluss so ausgebildet, dass ein zusätzliches in der Schließstellung des Kammerstängels verriegelndes Verriegelungselement ausgebildet ist. Indem ein zusätzliches in der Schließstellung des Kammerstängels verriegelndes Verriegelungselement ausgebildet ist, wird jedes unbeabsichtigte Verschieben der Verschlusshülse in Bezug auf den Verschlusskasten und somit auch ein unbeabsichtigtes Verschwenken des Kammerstängels und somit insgesamt ein Öffnen des Verschlusses hintangehalten.In order to avoid accidental or accidental opening of the closure and in particular a displacement of the closure sleeve with respect to the closure box with certainty, is in accordance with a preferred embodiment the invention, the closure is formed so that an additional in the closed position of the chamber stem locking locking element is formed. By forming an additional locking element which locks in the closed position of the chamber stem, any inadvertent displacement of the closure sleeve with respect to the closure box and thus also unintentional pivoting of the chamber stem and thus total opening of the closure are obstructed.
Indem, wie dies einer bevorzugten Weiterbildung der Erfindung entspricht, der Verschluss so ausgebildet ist, dass das zusätzliche Verriegelungselement als in eine Ausnehmung der Verschlusshülse eingreifender federbelasteter Keil ausgebildet ist, wird nicht nur ein unbeabsichtigtes Öffnen mit Sicherheit hintangehalten, sondern gleichzeitig sichergestellt, dass ein willentliches Öffnen des Verschlusses durch händisches Verschwenken des Kammerstängels ohne besonderen Kraftaufwand und ohne eine Mehrzahl von komplizierten mechanischen Entriegelungsschritten von einzelnen Elementen gewährleistet ist.By, as corresponds to a preferred embodiment of the invention, the closure is designed so that the additional locking element is formed as engaging in a recess of the closure sleeve spring-loaded wedge, not only accidental opening is withheld security, but at the same time ensures that a will Opening the closure by manual pivoting of the chamber stem is guaranteed without any special effort and without a plurality of complicated mechanical unlocking steps of individual elements.
Für einen besonders sicheren Eingriff und insbesondere, um ein unbeabsichtigtes Verklemmen des federbelasteten Keils in der Verschlusshülse mit Sicherheit hintanzuhalten, ist gemäß einer bevorzugten Weiterbildung die Vorrichtung so ausgebildet, dass der federbelastete Keil über eine gegenüber einer mit der Verschlusshülse Wechsel wirkende Anschlagfläche verkürzt ausgebildete Rastnase in die Ausnehmung der Verschlusshülse eingreift, in dem der federbelastete Keil über eine gegenüber einer mit der Verschlusshülse wechselwirkende Anschlagfläche verkürzt ausgebildete Rastnase in die Ausnehmung der Verschlusshülse eingreift, wird einerseits sichergestellt, dass durch das Anschlagen der Anschlagfläche an die Verschlusshülse ein zu tiefes Eindringen und somit Verklemmen des Keils in der Verschlusshülse hintangehalten wird und durch das Ausbilden einer verkürzt ausgebildeten Rastnase, welche mit einer komplementären Fläche der Verschlusshülse wechselwirkt, wird ein sicheres Verriegeln des Verschlusskastens mit der Verschlusshülse gewährleistet. Indem der Keil durch eine Feder belastet ist, insbesondere eine Druckfeder belastet ist, wird weiterhin sichergestellt, dass bei einem Verschließen des Verschlusses die Verriegelungstätigkeit zwischen Verschlusskasten und Verschlusshülse automatisch ohne Zutun des Benutzers der Schusswaffe durch den Druck der Druckfeder auf den Keil gewährleistet ist.For a particularly secure engagement and in particular to withstand accidental jamming of the spring-loaded wedge in the closure sleeve with certainty, the device is designed according to a preferred embodiment, that the spring-loaded wedge over a comparison with a closing sleeve acting stop surface shortened locking lug in engages the recess of the closure sleeve, in which the spring-loaded wedge engages over a recess which is shorter in relation to a stop surface interacting with the closure sleeve and engages in the recess of the closure sleeve, on the one hand ensures that by striking the stop surface of the closure sleeve too deep penetration and thus jamming of the wedge in the closure sleeve is retrained and by forming a shortened locking lug, which interacts with a complementary surface of the closure sleeve, a secure locking of Locking box with the sleeve ensures. By the wedge is loaded by a spring, in particular a compression spring is charged, it is further ensured that when a closure of the closure, the locking action between the closure box and closure sleeve is automatically ensured without the user of the firearm by the pressure of the compression spring on the wedge.
Für eine apparativ besonders einfache und gleichzeitig sichere und standfeste Lagerung des federbelasteten Keils in der Verschlusshülse und somit eine zuverlässige Verschwenkung desselben ist die Erfindung bevorzugt so weitergebildet, dass der federbelastete Keil an seinem der Rastnase abgewandten Ende abgerundet ausgebildet ist und dass der Keil mit seinem abgerundeten Ende beweglich in einer am Verschlusskasten festgelegten, eine komplementäre Auflagerfläche aufweisenden, Keilhalterung gehalten ist. Durch die abgerundete Ausbildung des federbelasteten Keils an seinem der Rastnase abgewandten Ende und der Ausbildung einer komplementären Auflagerfläche in der Keilhalterung wird einerseits eine ebenso glatte wie sichere Verschwenkung des Keils und gleichzeitig ein sicherer Halt desselben in dem Verschlusskasten gewährleistet.For a particularly simple apparatus and at the same time safe and stable storage of the spring-loaded wedge in the closure sleeve and thus a reliable pivoting thereof, the invention is preferably further developed so that the spring-loaded wedge is rounded at its end facing away from the locking lug and that the wedge with its rounded End movable in a set on the closure box, a complementary bearing surface having, wedge holder is held. Due to the rounded design of the spring-loaded wedge at its end facing away from the locking lug and the formation of a complementary support surface in the wedge support a smooth as well as safe pivoting of the wedge and at the same time a secure hold of the same in the closure box is guaranteed.
Dadurch, dass, wie dies einer bevorzugten Weiterbildung der Erfindung entspricht, der Kammerstängel über einen Bolzen mit dem federbelasteten Keil wechselwirkt, wird einerseits sichergestellt, dass ein unbeabsichtigter Austritt des Keils aus dem Verschlusskasten, insbesondere bei geöffneter Stellung des Verschlusses hintangehalten ist und andererseits wird durch die Wechselwirkung des Kammerstängels über einen Bolzen mit dem federbelasteten Keil gewährleistet, dass ausschließlich durch Betätigung des Kammerstängels der federbelastete Keil aus seiner Verriegelungsstellung geöffnet werden kann. Hiefür ist das willentliche Verschwenken durch den Benutzer des Kammerstängels von der geschlossenen in die geöffnete Position erforderlich, um die Verriegelung des federbelasteten Keils zu lösen.The fact that, as this corresponds to a preferred development of the invention, the chamber stem via a bolt interacts with the spring-loaded wedge, on the one hand ensures that an accidental leakage of the wedge from the closure box, especially in the open position of the closure is held back and on the other hand is ensured by the interaction of the Kammerstängels via a bolt with the spring-loaded wedge that exclusively by pressing the Kammerstängels the spring-loaded wedge can be opened from its locked position. For this purpose, the deliberate pivoting by the user of the chamber stem from the closed to the open position is required to release the locking of the spring-loaded wedge.
Für ein ruckfreies und insbesondere glattes Öffnen des federbelasteten Keils aus seiner Verriegelungsposition ist gemäß einer bevorzugten Weiterbildung die Erfindung so ausgebildet, dass der Kammerstängel an seiner dem Bolzen zugewandten Seite, eine mit dem Bolzen zusammenwirkende Keilfläche aufweist. Durch Ausbilden einer Keilfläche in dem Kammerstängel an der dem Bolzen zugewandten Seite, gelingt es bereits bei einer geringen Verschwenkung des Kammerstängels, einen ausreichenden Druck auf den Bolzen aufzubringen, um den federbelasteten Keil wiederum in Richtung eines vollflächigen Auflegens des Keils auf dem Verschlusskasten zu verschwenken und somit den Keil aus seiner Verriegelungsposition zu lösen.For a jerk-free and in particular smooth opening of the spring-loaded wedge from its locking position, the invention is designed so that the chamber stem has on its side facing the bolt, a cooperating with the bolt wedge surface according to a preferred embodiment. By forming a wedge surface in the chamber stem on the side facing the bolt, it is possible even with a small pivoting of the chamber stem to apply sufficient pressure on the bolt to turn the spring-loaded wedge in the direction of a full-surface application of the wedge on the closure box and thus to release the wedge from its locking position.
Die Keilfläche ist hierbei so ausgebildet, dass sie ausreichend große Steigung aufweist, um unmittelbar bei einer beginnenden Schwenkbewegung des Kammerstängels den Bolzen durch Druck zu beaufschlagen und somit die Verriegelung zu lösen.The wedge surface is in this case formed so that it has a sufficiently large pitch to apply the bolt by pressure immediately upon initial pivotal movement of the chamber stem and thus to release the lock.
Gemäß einer bevorzugten Weiterbildung ist die Keilfläche des Kammerstängels als Keilnut ausgebildet, wodurch eine sichere Führung des Bolzens im Inneren des Kammerstängels gewährgeleistet ist und somit ein unbeabsichtigtes Austreten und somit fehlerhaftes Entriegeln des Verschlusses mit Sicherheit hintanzuhalten.According to a preferred embodiment, the wedge surface of the chamber stem is formed as a keyway, whereby a secure guidance of the bolt is ensured in the interior of the chamber stem and thus withstand accidental leakage and thus faulty unlocking of the closure with certainty.
Wie dies einem Fachmann offensichtlich ist, ist es selbstverständlich auch möglich, den federbelasteten Keil beispielsweise durch einen Druck auf den Kammerstängel in Richtung zum Inneren des Verschlusskastens zu entriegeln, in welchem Fall beispielsweise ein geringes Spiel zwischen der Oberfläche der Verschlusshülse und dem Kammerstängel vorgesehen ist, um durch eine Druckbeaufschlagung des Kammerstängels in Richtung zum Inneren des Verschlusskastens und gleichzeitiger Verschwenkung des Kammerstängels den Verschluss der Schusswaffe sicher und zuverlässig zu entriegeln.As will be apparent to one skilled in the art, it is of course also possible to unlatch the spring-loaded wedge by, for example, pushing the chamber stem towards the interior of the closure box, in which case, for example, a slight clearance is provided between the surface of the closure sleeve and the chamber stem. in order to reliably and reliably unlock the closure of the firearm by pressurizing the chamber stem in the direction of the interior of the sealing box and simultaneously pivoting the chamber stem.
Im geschlossenen Zustand des Kammerstängels und somit auch im verschlossenen Zustand des Verschlusses wird, um ein unbeabsichtigtes Entriegeln und insbesondere ein Verschieben der Sperrstange mit Sicherheit hinanzuhalten, der Verschluss bevorzugt so ausgebildet, dass das zusätzliche Verriegelungselement als ein einer Öffnungs- und Schließbewegung des Kammerstängels folgendes Anschlagelement ausgebildet ist. Indem das zusätzliche Verriegelungselement als ein Anschlagelement ausgebildet ist, wird im geschlossenen Zustand des Verschlusses ein Anschlag für die Sperrstange zur Verfügung gestellt, welcher in Form eines Prellbocks ein unbeabsichtigtes Rückwärtsverschieben der Sperrstange mit Sicherheit hintanhält. Damit dieses zusätzliche Verriegelungselement und insbesondere das Anschlagelement einer Öffnungs- und Schließbewegung des Kammerstängels und somit des Verschlusses mit Sicherheit und störungsfrei folgt, ist es, wie dies einer Weiterbildung der Erfindung entspricht, mit einer mit der Anlenkachse des Kettenglieds wechselwirkenden Langlochführung ausgestattet. Die Langlochführung ist hierbei so angeordnet, dass im geöffneten Zustand des Kammerstängels das Anschlagelement in eine Position verschwenkt ist, in welcher die Sperrstange frei und ungehindert bewegbar ist und bei einer Schließbewegung des Kammerstängels greift die Anlenkachse des Kettenglieds, welche auch am Kammerstängel festgelegt ist, in die Langlochführung des Anschlagelements ein und zwingt das Anschlagelement durch die Schwenkbewegung des Kammerstängels in eine Position, in welcher die Anschlagfläche des Anschlagelements in Anlage an der Verschlussstange bzw. in unmittelbarer Nachbarschaft des Endes der Verschlussstange angeordnet ist, so dass eine Bewegung der Sperrstange in Richtung nach rückwärts mit Sicherheit verhindert ist. Bei einem neuerlichen Öffnen des Kammerstängels wird durch den Eingriff der Anlenkachse des Kettenglieds in die Langlochführung des Anschlagelements das Anschlagelement wiederum so verschwenkt, dass die Sperrstange freigegeben ist, wie dies einer Weiterbildung der Erfindung entspricht, gemäß welcher in einer Schließposition des Kammerstängels eine von einer der Langlochführung aufweisenden Endfläche abgewandte Anschlagfläche des Anschlagelements mit einer dem Kammerstängel zugewandten Endfläche der Sperrstange fluchtet bzw. an dieser Endfläche in Anlage angeordnet ist. Es ist somit das Anschlagelement durch den Kammerstängel zwangsgesteuert.In the closed state of the chamber stem and thus also in the closed state of the closure, in order to hold unintentional unlocking and in particular a displacement of the locking bar with certainty, the closure preferably designed so that the additional locking element as an opening and closing movement of the chamber stem following stop element is trained. By the additional locking element is formed as a stop element, a stop for the locking bar is provided in the closed state of the closure, which in the form of a buffer stop inadvertent backward displacement of the locking bar with certainty hinanhält. So that this additional locking element and in particular the stop element of an opening And closing movement of the chamber stem and thus the closure with security and trouble-free follows, it is, as this corresponds to a development of the invention, equipped with an interactive with the pivot axis of the chain link slot guide. The slot guide is in this case arranged so that in the open state of the chamber stem, the stop element is pivoted into a position in which the locking bar is freely and freely movable and during a closing movement of the chamber stem engages the pivot axis of the chain link, which is also fixed to the chamber stem in the slot guide of the stopper member and forces the stopper member by the pivotal movement of the chamber stem in a position in which the stop surface of the stopper member is arranged in contact with the closure rod or in the immediate vicinity of the end of the closure rod, so that a movement of the locking bar in the direction is prevented backwards with certainty. In a renewed opening of the chamber stem, the stop element is in turn pivoted by the engagement of the pivot axis of the chain link in the slot guide of the stop element, that the locking bar is released, as corresponds to a development of the invention, according to which in a closed position of the chamber stem one of the Slot end surface facing away from abutment surface of the stop element with a chamber stem facing the end surface of the locking bar is aligned or disposed on this end face in abutment. It is thus the stop element positively controlled by the chamber stem.
Mit einer derartigen Ausbildung wird ein unbeabsichtigtes Bewegen der Sperrstange und somit ein unbeabsichtigtes Öffnen der Verschlusshülse mit Sicherheit hintangehalten. Eine derartige zusätzliche Verriegelung ist insbesondere bei Verwendung von beispielsweise schadhafter Munition von Vorteil, bei welcher es in Folge von Fehlzündungen, Mehrfachzündungen bzw. verfrühten Zündungen der Munition geschehen kann, dass durch einen übermäßigen Druckaufbau die Sperrstange in Richtung zum Kammerstängel verschoben wird und gegebenenfalls die Totpunktlage des Kammerstängels überwunden werden kann und somit der Verschluss unbeabsichtigt geöffnet wird, wodurch es gegebenenfalls zu schweren Verletzungen des Benutzers kommen kann. Durch das Vorsehen einer parallel zu der Endfläche der Sperrstange angeordneten Anschlagfläche, welche ausschließlich durch eine Dreh-Schwenkbewegung verschwenkt werden kann, wird diese unbeabsichtigte, geradlinige Bewegung der Sperrstange in Richtung zu dem Kammerstängel mit Sicherheit hintangehalten und gleichzeitig ein unbeabsichtigtes Verschwenken des Anschlagelements verhindert, so dass ein unbeabsichtigtes Entriegeln des Kammerstängels und somit des Verschlusses mit Sicherheit hintangehalten ist.With such a design, an unintentional movement of the locking bar and thus an unintentional opening the locking sleeve with security. Such additional locking is particularly advantageous when using, for example, defective ammunition, in which it can happen as a result of misfires, multiple ignitions or premature ignitions of the ammunition that is displaced by excessive pressure build-up the locking bar towards the stanchion and possibly the dead center the stirrup can be overcome and thus the shutter is opened unintentionally, which may possibly lead to serious injury to the user. By providing a parallel to the end face of the locking bar arranged abutment surface, which can be pivoted exclusively by a rotary-pivoting movement, this unintentional, linear movement of the locking bar in the direction of the chamber stem is safely retarded and at the same time prevents unintentional pivoting of the stop element, so that inadvertent unlocking of the chamber stem and thus of the closure is certainly withheld.
