Description

Die Erfindung betrifft eine Vorrichtung zum Reduzieren des Rückpralls eines Verschlusses insbesondere eines Gasdruckladers.The invention relates to a device for reducing the rebound of a closure, in particular a gas pressure supercharger.

Aus der DE 42 07 25 A1 ist ein Verschlusskopf für eine Rohrwaffe mit zwei auf gegenüberliegenden Seiten angeordneten Riegeln für einen Verschluss, der einen Feder vorgespannten Schlagbolzen geführt aufnimmt bekannt. Um ein Zünden nur bei beidseitiger Verriegelung zu erreichen, wird vorgeschlagen, dass ein mit dem Zündhub beaufschlagbarer Hilfsschlagbolzen vorgesehen ist, der durch einen über zwei Distanzstücke in seiner Breite variablen Zwischenraum vom Schlagbolzen getrennt ist.From the DE 42 07 25 A1 is a closure head for a gun barrel with two arranged on opposite sides bars for a closure which receives a spring biased firing pin is known. In order to achieve ignition only with bilateral locking, it is proposed that a can be acted upon with the ignition stroke auxiliary impact bolt is provided, which is separated by a two spacers in its width variable gap from the firing pin.

Dieser Konstruktion liegt das Problem zugrunde, dass bei vollautomatischen Waffen, auch bedingt durch die hohe Schusskadenz, der Verschluss, Verriegelungsschieber und alle dazugehörigen beweglichen Teile auf das nahezu unbewegte Waffenrohr prallen. Dieses kann zu einem Rückprallen, insbesondere des Verriegelungsschiebers, kommen, was im ungünstigsten Fall ein Entriegeln der Waffe mit sich bringen könnte, wenn der durch das Rückprallen zurückgelegte Weg zu groß ist. Wenn sich dann auch noch die Anzündung verzögert, ist ein Schuss bei entriegeltem Verschluss möglich.This construction is based on the problem that in fully automatic weapons, also due to the high firing cadences, the shutter, locking slide and all the associated moving parts bounce on the almost stationary gun barrel. This can come to a rebound, in particular of the locking slide, which could bring in the worst case, unlocking the weapon with it when the distance traveled by the rebound path is too large. If then also the ignition delays, a shot with unlocked lock is possible.

Aus der DE 195 36 660 A1 ist ein derartiges Verschlusssystem für eine Rohrwaffe bekannt. Dabei sind zwei jeweils um eine Achse schwenkbare Sperrhebel vorgesehen, deren jeweils erster Arm durch jeweils einen Riegel beaufschlagbar ist, derart, dass beim Verriegeln des Verschlusses der erste Arm des jeweiligen Sperrhebels zum Schlagbolzen hin schwenkbar und der zweite Arm des jewelligen Sperrhebels vom Schlagbolzen weg schwenkbar ist, sodass der Schlagbolzen in seiner Zündposition verschiebbar ist. Um zu erreichen, dass ein derartiges Verschlusssystem einfach aufgebaut und eine Zündung der Patrone nur dann erfolgt, wenn der Verschluss auf belden Selten sicher verriegelt ist, wird vorgeschlagen, dass der Schlagbolzen zwei gegenüberliegende Fangkanten enthält, in die der jeweils zweite Arm der Sperrhebel in der Verriegelungsposition des Schlagbolzens eingreift.From the DE 195 36 660 A1 Such a closure system for a gun is known. In this case, two each pivotable about an axis locking lever are provided, each of which first arm can be acted upon by a respective latch, such that when locking the shutter, the first arm of the respective locking lever to the firing pin pivotally and the second arm of the jewelligen locking lever is pivotally away from the firing pin, so that the firing pin is slidable in its firing position. In order to achieve such a closure system is simple and ignition of the cartridge takes place only when the shutter is locked securely on Belden rare, it is proposed that the firing pin contains two opposite catching edges, in which the respective second arm of the locking lever in the Locking position of the firing pin engages.

Aktuelle Meßnahmen sind beispielsweise das Einbinden von Nachschlagmassen oder Hebelmechanismen, wie das Einbinden einer Wippe. Diese Lösungen dienen dazu, die Vorlaufanergie Insbesondere des Verriegelungsschiebers geringfügig zu reduzieren. Nachteilig ist, dass es bei starker Verschrnutzung, schlechtem Schrnierzustand und großer Kälte zu einer erheblichen Reduktion der Verschlussgeschwindigkeit führen kann, sodass die zuverlässige Anzündung der Patrone nicht mehr gewährleistet wird.Current measures include, for example, the integration of reference weights or lever mechanisms, such as the integration of a rocker. These solutions serve to slightly reduce the flow anergy, in particular of the locking slide. The disadvantage is that it can lead to a significant reduction in the shutter speed at heavy Verschrutzung, bad Schrnierzustand and great cold, so that the reliable ignition of the cartridge is no longer guaranteed.

Die WO 80/02066 A1 betrifft eine Antiprellvorrichtung für hin und her bewegte Bolzenanordnungen automatischer Kanonen. Die Antiprellvorrichtung umfasst ein Teil, das mit dem Bolzenträger verbunden ist sowie reibungsverrlegeinde Einrichtungen, die zwischen dem Teil und am Verschluss befestigten Abschnitten angeordnet sind, wenn sich der Bolzenträger nahe am Verschluss befindet. Tragheitseinrichtungen verursachen, dass die reibungsverriegelnden Einrichtungen lösbar das Teil am feststehenden Teil der Kanone verriegeln, sodass ein Prellen des Bolzenträgers vom Verschluss im Wesentlichen unterbrochen wird. Das Tell besteht aus einem Kolben, der den Bolzenträger bei seinen Bewegungen stützt. Die Trägheitseinrichtung umfasst eine Gruppe von Gewichten, die gleitend am Kolben zur Bewegung entlang des Kolbens montiert sind. Die reibungsverriegeinden Einrichtungen umfassen eine Gruppe von expandierenden Klemmhülsen, die gleitend am Kolben zur Bewegung entlang des Kolbens angebracht sind. Während der Zeitspanne, In der sich die Bolzensnordnung und der Verbindungskolben rückwärts bewegen, bewirken die Trägheitskräfte, dass die Gewichte und die Hülsen gegen die Kolbenanschläge oder Schultern gedrückt bleiben. Wenn die Bolzenanordnung und der Verbindungskolben durch einen Puffer gestoppt werden, bewirken wiederum die Tragheitskräfte, dass die Gewichte und Hülsen ihre Rückwärtsbewegung fortsetzen, bis sie auf eine Endhülse auftreffen.The WO 80/02066 A1 relates to an anti-bounce device for reciprocating bolt assemblies of automatic cannons. The anti-bump device includes a part connected to the bolt carrier and anti-friction devices disposed between the part and portions attached to the buckle when the bolt carrier is close to the buckle. Belness devices cause the friction-locking devices to releasably lock the part to the stationary part of the cannon so that bouncing of the bolt carrier from the closure is substantially interrupted. The Tell consists of a piston that supports the bolt carrier during its movements. The inertia device includes a set of weights that are slidably mounted on the piston for movement along the piston. The friction-locked devices comprise a group of expanding collets slidably mounted on the piston for movement along the piston. During the period in which the pin assembly and the connecting piston move backward, the inertial forces cause the weights and sleeves to remain pressed against the piston stops or shoulders. Again, when the bolt assembly and the connecting piston are stopped by a buffer, the inertial forces cause the weights and sleeves to continue their reverse motion until they impact a ferrule.

Die CH 474 734 A beschäftigt sich mit einer selbsttägigen Feuerwaffe mit einem Verschlusskörper, einem Steuerstück und Schließfedern. Das Steuerstuck unterstellt hierbei In bekannter Art und Weise Riegel, die ihrerseits in ein Verschlussgehäusa gedrückt werden. Während die Hülsen sich In die vordere Endposition bewegen, laufen die Stirnflächen der Ansätze der Hülse gegen die Flächen der Sperrbolzen und drücken diese weg. Kurz bevor das Steuerstück gegen den Verschlusskopf prallt, werden die Sperrbolzen unter Federkraft zurückge-drückt und kommen nunmehr hinter den Flächen am Ansatz zum Anliegen. Beim Zurückprellen des Steuerstücks stoßen die unteren Flächen der Federhülsenansätze gegen die Flächen der Sperrbolzen an. Dadurch wird eine über die Stellung hinausgehende Bewegung der Federhülsen und damit des Steuerstücks vorerst vermieden. Zur Rückwärtsbewegung des Steuerstücks wird dieses mittels einer Entriegelungsstange entriegelt.The CH 474 734 A deals with a self-contained firearm with a closure body, a control piece and closing springs. In this case, the control stucco assumes, in a known manner, bars which in turn are pressed into a closure housing. As the sleeves move to the front end position, the faces of the lugs of the Sleeve against the surfaces of the locking pin and push it away. Just before the control piece bounces against the closure head, the locking pins are zurückge-pressed under spring force and now come behind the surfaces at the base to concern. When rebounding the control piece, the lower surfaces of the spring sleeve approaches abut against the surfaces of the locking pin. As a result, a position beyond the movement of the spring sleeves and thus the control piece is initially avoided. For the backward movement of the control piece this is unlocked by means of an unlocking rod.

Auch die US 3,821,920 A betrifft eine Fangvorrichtung an einer selbsttätigen Feuerwaffe.Also the US 3,821,920 A relates to a safety gear on an automatic firearm.

Hier stellt sich die Erfindung die Aufgabe, eine Vorrichtung aufzuzeigen, die ein Öffnen eines zurückprallenden Verschlusses nach dem Zuführen der Munition verhindert.Here, the invention has the object to provide a device that prevents the opening of a rebound closure after feeding the ammunition.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgezeigt. ,The object is achieved by the features of claim 1. Advantageous embodiments are shown in the subclaims. .

Der Erfindung liegt die idee zugrunde, dass es ausreichen würde, ein Prellen nach dem Auf-schlag durch Einbinden zusätzlicher Massen zu minimieren und so den Verlust an Verschlussvorlaufenergie möglichst gering zu halten. Dieses wird dadurch erreicht, dass ein rückprallender Verriegelungsschierber des Verschlusses mit einer Zusatzmasse gekoppelt wird, sodass ein Grossteil der Rückprallenergie durch die Zusatzmasse aufgenommen und der Schieber dieser Energie entledigt wird. Dann wird nach dem Zurücklegen eines bestimmten Weges, wenn ein Öffnen des Verschlusses nicht mehr möglich ist, die Unterstellung des Schiebers gelöst und dieser kann seine Funktion, das Verkellen der Stützklappen des Verschlusses, ungehindert fortsetzen.The invention is based on the idea that it would be sufficient to minimize bounce after impact by incorporating additional masses and thus to minimize the loss of closing lead energy. This is achieved in that a rebounding locking shear of the closure is coupled with an additional mass, so that a large part of the rebound energy is absorbed by the additional mass and the slide of this energy is disposed of. Then, after covering a certain path, when opening of the closure is no longer possible, the subordination of the slider is released and this can continue its function, the concatenation of the support flaps of the closure, unhindered.

In Fig. 1 ist ein Verschluss 1 in seiner verriegelten Position dargestellt. Mit 2 ist ein Verriegelungsschieber und mit 3 ein Verschlusskopf gekennzeichnet. Die Verriegelung des Verschlusses 1 im nicht näher dargestellten Waffengehäuse erfolgt über Stützklappen 4, die dazu vom Verriegelungsschieber 2 unterstellt werden.In Fig. 1 a closure 1 is shown in its locked position. 2 is a locking slide and 3 is a closure head. The locking of the closure 1 in the weapon housing, not shown, via support flaps 4, which are assumed by the locking slide 2.

Im geöffneten Zustand der Waffe liegen die Stützklappen 4 und der vordere Teil des Verriegelungsschiebers 2 stirnseitig aneinander an. Am vorderen Ende des Verschlusses ist eine Anlage 5 für eine nicht näher dargestellte Patrone angedeutet. Diese wird in Funktion durch einen Schlagbolzen 6 gezündet.In the open state of the weapon are the support flaps 4 and the front part of the locking slide 2 frontally to each other. At the front end of the closure a system 5 is indicated for a cartridge, not shown. This is ignited in function by a firing pin 6.

Der Verschluss 1 wird durch Form- oder Kraftschluss zweier Mitnehmemocken 21 und dem Verriegelungsschieber 2 des Verschlusses 1 bewegt. Die Mitnehmernocken 21 sind dabei Bestandteil zweier, beidseitig am Verschluss 1 angeordneter Schließfedervorrichtungen 20. Jede Schließfedervorrichtung 20 beinhaltet eine Unterbaugruppe Schließfederrohr 22. Eine Anschlagbuchse 23 ist das vordere Lager im Waffengehäuse. Die Schließvorrichtung 20 wird mit Hilfe eines Verriegelungsknopfes 24 im Waffengehäuse gelagert. Ein Riegel 25 dient als Sicherung gegen unabsichtliches Lösen. Der Verriegelungsknopf 24 und ein Federhülsenanschlag 26 sind auf das Schließfederrohr 22 auf Anschlag eingeschraubt und gesichert (22'-Schließfederrohr - vollständig). Mit 27 ist eine Schließfederhülse mit Mitnehmernocken 21 gekennzeichnet. Weiterer Baugruppen sind eine Schließfeder 28 sowie eine Federkappe 29 (Fig. 2). Diese Mitnehmernocken 21 greifen in Freisparrungen 10 am Verriegelungsschieber 2 formschlüssig anThe closure 1 is moved by positive or positive connection of two driving cam 21 and the locking slide 2 of the closure 1. The driving cam 21 are part of two, arranged on both sides of the closure 1 Schließfedervorrichtungen 20. Each Schließfedervorrichtung 20 includes a subassembly Schließfederrohr 22. A stop bushing 23 is the front bearing in the weapon housing. The locking device 20 is mounted by means of a locking button 24 in the weapon housing. A latch 25 serves as a safeguard against unintentional release. The locking button 24 and a spring sleeve stop 26 are screwed onto the closing spring tube 22 to stop and secured (22'-Schließfederrohr - complete). 27 with a closing spring sleeve is characterized with driving cam 21. Further components are a closing spring 28 and a spring cap 29 (FIG. Fig. 2 ). These driving cams 21 engage in releasing rests 10 on the locking slide 2 in a form-fitting manner

Mit dem Verschluss 1 wird die Patrone in ein nicht näher dargestelltes Waffenrohr bzw. Patronenlager des Waffenrohres eingebracht. Die Beschleunigung des Verschlusses 1 erfolgt hierbei durch Beaufschlagung mit Gas durch einen nicht näher dargestellten Gaskolben. Wenn der Verschlusskopf 3 gegen das Waffengehäuse anschlägt, wird der Verrieglungsschieber 2 weiter bewegt und schiebt die Stützklappen 4 in entsprechende Ausnehmungen des Waffengehäuses. Dabei prallt der Verriegelungsschieber 2 gegen einen starren Anschlag 7 am Verschlusskopf 3. Durch diesen Aufprall werden der Verriegelungsschieber 2 als auch der Verschlusskopf 3 entgegen ihrer Vorlaufbewegung zurückbewegt.With the closure 1, the cartridge is introduced into a weapon tube or cartridge chamber of the weapon barrel not shown in detail. The acceleration of the closure 1 takes place here by applying gas through a gas piston, not shown. When the closure head 3 abuts against the weapon housing, the Verrieglungsschieber 2 is moved further and pushes the support flaps 4 in corresponding recesses of the weapon housing. In this case, the locking slide 2 rebounds against a rigid stop 7 on the closure head 3. By this impact, the locking slide 2 and the closure head 3 are moved back against their forward movement.

Die Schließfedern des Verriegelungsschiebers 2 sollten in diesem Fall ein Öffnen verhindern, besitzen jedoch häufig nicht die Kraft, die Rückprallbewegung zu verhindern, sodass im ungünstigsten Fall die Stützklappen 4 aus den Ausnehmungen des Waffengehäuses in Richtung des Verschlusskopfes 3 gleiten und die Verriegelung gelöst werden könnte. Diese Rückprallbewegung wird nunmehr dadurch Einbinden einer Rückprallsperre 11 in den Rücklaufweg des Verriegelungsschiebers 2 verhindert. Die Rückprallsperre 11 kann über eine Verbindung 30 als zusätzliches Teil mit dem Waffenkreis (bewegliche Teile) verbunden werden.The closing springs of the locking slide 2 should prevent opening in this case, but often do not have the force to prevent the rebound, so in the worst case, the support flaps 4 from the recesses of the gun housing slide in the direction of the closure head 3 and the lock could be solved. This rebound movement is now prevented by integrating a rebound lock 11 in the return path of the locking slide 2. The rebound lock 11 can be connected via a connection 30 as an additional part with the weapon circle (moving parts).

Die Rückprallsperre 11 umfasst dabei eine Zusatzmasse 12, die beim Zurückprellen des Verriegelungsschiebers 2 an diesen angreift, sodass der Verriegelungsschieber 2 in seiner Rückwärtsbewegung gedämpft und damit die Bewegungsenergie reduziert wird. Die Zusatzmasse 11 wird dabei bevorzugt durch bewegbare Waffenteile gebildet.The rebound lock 11 comprises an additional mass 12, which acts on the rebounding of the locking slide 2 to this, so that the locking slide 2 is damped in its backward movement and thus the kinetic energy is reduced. The additional mass 11 is preferably formed by movable weapon parts.

An der Zusatzmasse 12 ist eine Klinke 13 eingebunden (Fig. 4), die ihrerseits vorzugsweise an einen Vorsprung der Schließfederhülse 27 an- bzw. eingreift. Dieses Eingreifen erfolgt dann, wenn die Schließfederhülse 27 den maximalen Anschlag 7 erreicht hat und nun durch die Aufprallkraft zurück bewegt wird (Fig. 3). Dabei wird die Klinke 13 aus ihrem Freiraum bewegt, wodurch eine Unterstellung 14 in diesen hineingleiten kann (beispielsweise federunterstützend). Ebenfalls mitgenommen wird eine Halterung 16, wodurch eine Art Pleuel 17 in den oberen Abschnitt einer Langlochkonstruktion 15 gebracht wird. Durch die nunmehr hergestellte Verbindung nehmen die Schließfederhülse 27 und damit der Verriegelungsschieber 2 die Zusatzmassen 12 mit sich mit. Dadurch wird die Rücklaufenergie abgebaut.At the additional mass 12 a pawl 13 is involved ( Fig. 4 ), which in turn preferably on a projection of the closing spring sleeve 27 or engages. This intervention takes place when the closing spring sleeve 27 has reached the maximum stop 7 and is now moved back by the impact force ( Fig. 3 ). In this case, the pawl 13 is moved out of its free space, whereby a sub-position 14 can slide into this (for example spring-assisting). Also taken a bracket 16, whereby a kind of connecting rod 17 is brought into the upper portion of a slot construction 15. By now established connection take the closing spring sleeve 27 and thus the locking slide 2, the additional masses 12 with. As a result, the return energy is reduced.

Während der Verbindung ist die Klinke 13 somit unterstellt. Um diese Unterstellung nach einem vorbestimmbaren Weg zu lösen, wirkt die Unterstellung 14 der Rückprallsperre 11 erneut mit der Langlochkonstruktion 15 zusammen. Die Unterstellung 14 wird über die Halterung 16 und dem Pleuel 17 oder dergleichen, entlang des schräg eingebundenen Langlochs 15 geführt, sodass, wenn der Pleuel 17 seine untere Endposition erreicht hat und mit der Halterung 16 auch die Unterstellung 14 verschoben worden ist. Dadurch kann die Klinke 13 ihrerseits in den Freiraum hineingleiten und den Vorsprung der Schließfederhülse 27 freigeben. Die möglicherweise noch verbliebene Energie reicht ihrerseits nicht aus, den Verriegelungsschieber 2 weiter zu bewegen, sodass dieser die Unterstellung der Stützklappen 4 beibehält.During the connection, the pawl 13 is thus assumed. In order to solve this assumption after a predeterminable way, the subordinate position 14 of the rebound lock 11 cooperates again with the slot construction 15. The sub 14 is performed on the bracket 16 and the connecting rod 17 or the like, along the obliquely incorporated slot 15, so that when the connecting rod 17 has reached its lower end position and with the bracket 16 and the sub-position 14 has been moved. As a result, the pawl 13 in turn slide into the free space and release the projection of the closing spring sleeve 27. The possibly remaining energy in turn is not enough to move the locking slide 2 on, so that this maintains the assumption of the support flaps 4.

Der Mitführweg der Rückprallsperre 11 wird somit durch die Länge / Anstiegswinkel des Langlochs 15 bestimmt. Die Menge bzw. das Gewicht der Zusatzmasse 12 ist auf den Aufund Rückprall des Verriegelungsschiebers 2 abstimmbar.The Mitführweg the rebound lock 11 is thus determined by the length / slope angle of the slot 15. The amount or weight of the additional mass 12 is tuned to the up and rebound of the locking slide 2.

Recoil catch for a breech (1) of, in particular, a gas-operated self-loader, having at least two support flaps (4), a bolt head (3), a locking slide (2) and two recoil spring apparatuses (20) on both sides of the breech (1) with drive cams (21) which are connected in a positive and non-positive manner to the locking slide (2), characterized in that the recoil catch (11) is incorporated in the recoil path of the locking slide (2), with the result that, during the recoil of the locking slide (2), an additional mass (12) acts on it and the rearward movement of the locking slide (2) is damped and therefore the kinetic energy is reduced, the locking slide (2) being acted on by a pawl (13) on the recoil catch (11) via a projection on a recoil spring sleeve (27) of the recoil spring device (20), and the pawl (13) being detented.
  2. Recoil catch according to Claim 1, characterized in that the detent (14) of the recoil catch (11) interacts via a holding device (16) and a connecting rod (17) with a slot construction (15) which is incorporated obliquely in the recoil catch (11), with the result that the detent (14) can be established or released.
  3. Recoil catch according to Claim 2, characterized in that the holding device (16) which moves a connecting rod (17) into the upper section of the slot construction (15) is driven for the detent (14).
  4. Recoil catch according to Claim 2 or 3, characterized in that, in order to release the detent (14) after a predefined travel, the detent is guided along the slot (15) via the holding device (16), the connecting rod (17) assuming a lower end position.
  5. Recoil catch according to one of Claims 1 to 4, characterized in that the additional mass (12) is formed by weapon-movable parts.
  6. Recoil catch according to one of Claims 1 to 5, characterized in that the recoil catch (11) can be connected via a connection (30) to additional movable parts of the weapon system.
