Description

Die Erfindung betrifft einen Keilverschluss für eine Rohrwaffe mit einem an einem Waffenrohr heckseitig verbundenen Bodenstück und einem in dem Bodenstück senkrecht zur Seelenachse des Waffenrohres in einer Führung des Bodenstückes verschiebbaren, eine Lademulde aufweisenden Verschlusskeil, wobei das Teilschließen des Verschlusskeiles mittels mindestens einer Haltevorrichtung, die hinter der Lademulde des Verschlusskellas am Bodenstück angeordnet ist, vorgenommen wird. Dabei wird ein Sperrelement der Haltevorrichtung ausgefahren, wenn der Ansetzer zum Laden einer Patrone In die Lademulde fährt, welches bei der Schließbewegung des Verschlusskeiles diesen dann in der teilgeschlossenen Position blockiert. In der teilsweise geschlossenen Position wird der Verschlusskeil von der Sperreinrichtung blockiert..The invention relates to a wedge lock for a gun with a rear side connected to a gun barrel bottom piece and a displaceable in the bottom piece perpendicular to the axis of the weapon barrel in a leadership of the bottom piece, a loading tray having closure wedge, wherein the partial closing of the closure wedge by means of at least one holding device behind the loading trough of the closure cella is arranged on the bottom piece is made. In this case, a blocking element of the holding device is extended when the piecing for loading a cartridge moves into the loading trough, which then blocked in the closing movement of the closure wedge this in the partially closed position. In the partially closed position the closing wedge is blocked by the locking device.

Ein derartiger Keilverschluse ist beispielsweise aus der DE 38 39 496 C2 bekannt. Dabei wird nach dem Ladevorgang der jeweiligen Patrone mittels eines Ansetzers einer Ladeeinrichtung der Verschlusskeil zunächst von einer geöffneten Position in eine teilweise geschlossene Position verschoben und der Verschlusskeil in dieser durch eine die Öffnerwelle des Verschlusskelles blockierende Sperreinrichtung blockiert. Dadurch soll einerseits beim Zurückfahren des Ansetzers ein Zurückrutschen der jeweiligen Patrone aus dem Ladungsraum durch den Verschlusskeil verhindert werden. Andererseits soll sichergestellt werden, dass der schließende Verschlusskeil nicht mit dem Ansetzer kollidieren kann.Such a wedge lock is for example from the DE 38 39 496 C2 known. In this case, after the loading of the respective cartridge by means of a piecing a loading device of the shutter wedge initially moved from an open position to a partially closed position and the shutter wedge blocked in this by blocking the opener shaft of the shutter blocking device. This is intended, on the one hand, to prevent the respective cartridge from slipping out of the cargo space through the closing wedge when the piecing-back device is moved back. On the other hand, it should be ensured that the closing wedge can not collide with the piecing.

Da das Verschieben bei diesen bekannten Keliverschluss in seine vollständig geschlossene Position, nachdem der Ansetzer der Ladeeinrichtung die Lademulde des Verschlusskeiles passiert hat, nicht automatisch erfolgt, muss dies manuell oder über einen Aktuator ausgelöst werden. Hierzu sind weitere Funktionselemente erforderlich, welche die Störanfälligkeit, das Gewicht und auch die für den Ladevorgang erforderliche Zeit heraufsetzen.Since the shift in this known Keli closed in its fully closed position, after the piecing of the charger has passed the loading trough of the closure wedge, not automatically, this must be triggered manually or via an actuator. For this purpose, further functional elements are required, which increase the susceptibility, the weight and also the time required for the charging process.

Die US 5,481,958 A offenbart eine Waffe mit bewegbarem Verschlusskeil, der zwischen einer geschlossenen Position und einer offenen Position beweglich gehalten ist. Ein Riegel dient seinerseits dazu, den Verschlusskeil in seiner offenen Stellung zu halten. In dieser Position wird eine Munition mit Hilfe eines Laderohnes In eine Patronenkammer des Waffenrohres eingebracht. Auf dem Laderohr sind Mittel montiert, die den Riegel in eine entriegelte Position bringen, während das Laderohr auf die gegenüberliegende Waffenkammer verschoben wird. Dadurch wird der Verschlusskeil vom Laderohr immer erst dann entriegelt, wenn dieses von der Munitionskammer entfernt ist und nachdem die Munition eingelegt wurde. Ein Zurückrutschen der jeweiligen Patrone aus der Waffenkammer kann mit dieser Konstruktion nicht ausgeschlossen werdenThe US 5,481,958 A discloses a movable shutter wedge weapon moveable between a closed position and an open position. A latch in turn serves to hold the shutter wedge in its open position. In this position, an ammunition is introduced by means of a loader into a cartridge chamber of the weapon barrel. Means are mounted on the loading tube which bring the latch to an unlocked position while shifting the loading tube to the opposite armory. As a result, the shutter wedge of the charging tube is always unlocked only when it is removed from the ammunition chamber and after the ammunition has been inserted. A slipping back of each cartridge from the armory can not be excluded with this construction

Der Erfindung liegt die Aufgabe zugrunde, einen Keilverschluss der eingangs erwähnten Art anzugeben, bei dem nach dem vollständigen Laden einer Patrone der Verschlusskeil automatisch geschlossen wird, nachdem der Ansetzer die Lademulde des Verschlusskeiles passiert hat.The invention has for its object to provide a wedge lock of the type mentioned, in which after the complete loading of a cartridge, the closure wedge is automatically closed after the piecing has passed the loading trough of the closure wedge.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

Die Erfindung beruht im Wesentlichen auf dem Gedanken, das Teilschließen des Verschlusskeiles mittels mindestens einer Haltevorrichtung, die hinter der Lademulde des Verschlusskeiles am Bodenstück angeordnet ist, vorzunehmen. Dabei wird ein Sperrelement der Haltevorrichtung ausgefahren, wenn der Ansetzer zum Laden einer Patrone in die Lademulde fährt, welches bei der Schließbewegung des Verschlusskeiles diesen dann in der teilgeschlossenen Position blockiert. Sobald der Ansetzer die Lademulde des Verschlusskeiles verlassen hat, wird die Unterstellung des Verschlusskeiles durch das Sperrelement automatisch aufgehoben und der Keilschließvorgang beendet.The invention is based essentially on the idea of partial closure of the closure wedge by means of at least one holding device which is arranged behind the loading trough of the closure wedge on the bottom piece. In this case, a blocking element of the holding device is extended when the piecing runs for loading a cartridge in the loading trough, which then blocked in the closing movement of the closure wedge this in the partially closed position. Once the piecing has left the loading trough of the closure wedge, the subordination of the closure wedge is automatically canceled by the blocking element and the wedge closing process terminated.

Das Sperrelement steht dabei mit einer Betätigungseinrichtung der Haltevorrichtung in Wirkverbindung, die ein bewegliches Betätigungsteil umfasst, welches durch mindestens ein Rückstellelement in einer Ausgangsposition gehalten wird, bei der sich das Sperrelement in seiner Ruheposition befindet, und welches bei dem Ansetzen der Munition durch den Ansetzer des Ladeautomaten gegen den Druck des Rückstellelementes in eine Betätigungsposition gedrückt wird und dabei das Sperrelement von seiner Ruheposition in seine Sperrposition verschiebt.The blocking element is in operative connection with an actuating device of the holding device, which comprises a movable actuating part, which is held by at least one return element in a starting position, wherein the blocking element is in its rest position, and which in the preparation of the ammunition by the piecing of Loading machine is pressed against the pressure of the return element in an operating position and thereby shifts the locking element from its rest position to its locked position.

Bei einer bevorzugten Ausführungsform der Erfindung ist die in dem Bodenstück enthaltene Führung des Verschlusskeiles heckseitig durch zwei den Verschlusskeil umgreifende Führungsleisten des Bodenstückes begrenzt, wobei in einer der einander zugewandten Stirnseiten die Haltevorrichtung befestigt ist.In a preferred embodiment of the invention, the guide of the closure wedge contained in the bottom piece is delimited on the rear side by two guide strips of the bottom piece encompassing the closure wedge, the holding device being fastened in one of the mutually facing end faces.

Vorzugsweise ist das Sperrelement in der Halteeinrichtung von einer Ruheposition in eine Sperrposition verschiebbar angeordnet.Preferably, the blocking element is slidably disposed in the holding device from a rest position to a blocking position.

Das Sperrelement ist vorzugsweise bolzenförmig ausgebildet und kann auf seiner der entsprechenden Anschlagsfläche des Verschlusskeiles zugewandten Seite abgeflacht ausgebildet sein.The blocking element is preferably formed bolt-shaped and may be formed flattened on its side facing the corresponding abutment surface of the closure wedge.

Die Anschlagsfläche des Verschlusskeiles kann heckseitig verjüngend abgeschrägt ausgebildet sein, wobei die Steigung der abgeschrägten Anschlagsfläche derart bemessen ist, dass keine Selbsthemmung des gegen die Anschlagsfläche gedrückten abgeflachten, bolzenförmigen Sperrelementes erfolgt, sodass das Sperrelement sich selbständig gegen die Schließkraft des Verschlusskeiles verschieben kann, wenn es hieran nicht durch eine Blockierung des Betätigungsteiles durch den Ansetzer des Ladeautomaten gehindert werden würde.The abutment surface of the closure wedge can be tapered beveled on the rear side, wherein the slope of the beveled abutment surface so dimensioned is that no self-locking of the abutment surface pressed flattened, bolt-shaped locking element takes place, so that the locking element can move independently against the closing force of the closure wedge, if it would not be prevented by a blocking of the operating part by the piecing of the loading machine.

Bei einer bevorzugten Ausführungsform der Erfindung handelt es sich bei dem Betätigungsteil der Haltevorrichtung um einen ersten Schwenkhebel, dessen erstes Ende um eine halteeinrichtungsfeste erste Drehachse schwenkbar ist und dessen zweites Ende seitlich in den von dem Ansetzer beim Laden der Munition zu passierenden Raum des Bodenstückes ragt, wobei im Bereich des zweiten Endes des ersten Schwenkhebels ein zweiter Schwenkhebel um eine durch den ersten Schwenkhebel gehende zweite Drehachse schwenkbar gelagert ist, dessen der zweiten Drehachse abgewandtes Ende um eine dritte Drehachse gelenkig mit dem in einer axialen Führung der Halteeinrichtung verschiebbar angeordneten Sperrelement verbunden ist.In a preferred embodiment of the invention, the actuating part of the holding device is a first pivoting lever whose first end is pivotable about a holder-fixed first axis of rotation and the second end of which projects laterally into the space of the bottom piece to be passed by the piecemeal during loading of the ammunition, wherein in the region of the second end of the first pivot lever, a second pivot lever is pivotally mounted about a passing through the first pivot lever second axis of rotation, the end remote from the second axis of rotation about a third axis of rotation is pivotally connected to the displaceable in an axial guide of the holding device arranged blocking element.

Vorzugsweise sollten die Lagen der drei Drehachsen derart gewählt sein, dass sie in der Sperrposition des Sperrelementes im Wesentlichen auf einer Linie liegen. Dadurch wird erreicht, dass die Schließkraft des Verschlusskeiles, die auf das bolzenförmige Sperrelement wirkt, kein öffnendes Moment auf das Betätigungsteil der Haltevorrichtung bewirkt und der Verschlusskeil zuverlässig in der teilweise geschlossenen Position gehalten wird.Preferably, the layers of the three axes of rotation should be selected such that they lie in a substantially line in the blocking position of the blocking element. This ensures that the closing force of the closure wedge, which acts on the bolt-shaped blocking element, causes no opening moment on the actuating part of the holding device and the closure wedge is reliably held in the partially closed position.

Bei einem Ausführungsbeispiel der Erfindung sind der erste Schwenkhebel klappenförmig und der zweite Schwenkhebel als Schwinge ausgebildet.In one embodiment of the invention, the first pivot lever are flap-shaped and the second pivot lever formed as a rocker.

Als besonders vorteilhaft hat es sich erwiesen, wenn die Sperreinrichtung zwei Haltevorrichtungen umfasst, welche heckseitig hinter dem Verschlusskeil beidseitig der Lademulde des Verschlusskeiles am Bodenstück angeordnet sind.It has proven to be particularly advantageous if the locking device comprises two holding devices, which are arranged on the rear side behind the closure wedge on both sides of the loading trough of the closure wedge on the bottom piece.

Ein weiterer Vorteil dieser Konstruktion liegt darin, dass keine zusätzliche Sensoren oder Aktuatoren erforderlich sind.Another advantage of this design is that no additional sensors or actuators are required.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden, anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:

In Fig.1 ist mit 1 eine Rohrwaffe bezeichnet, welche ein Waffenrohr 2 mit einem heckseitig angeordneten Keilverschluss 3 (hier ein Fallkeilverschluss) umfasst. Der Keilverschluss 3 besteht im Wesentlichen aus einem mit dem Waffenrohr 2 verbundenen Bodenstück 4 und einem in dem Bodenstück 4 senkrecht zur Seelenachse 5 des Waffenrohres 2 in einer Führung 6 des Bodenstückes 4 verschiebbaren, eine Lademulde 7 aufweisenden Verschlusskeil 8. Dabei ist die in dem Bodenstück 4 enthaltene Führung 6 des Verschlusskeiles 8 heckseitig durch zwei den Verschlusskeil 8 umgreifende Führungsleisten 9 des Bodenstückes 4 begrenzt.In Fig.1 1 denotes a barrel weapon, which comprises a weapon barrel 2 with a wedge closure 3 arranged at the rear (here a drop wedge closure). The wedge lock 3 consists essentially of a connected to the gun barrel 2 bottom piece 4 and in the bottom piece 4 perpendicular to the axis of the shaft 5 of the gun barrel 2 in a guide 6 of the bottom piece 4 displaceable, a loading tray 7 having shutter wedge 8. It is in the bottom piece 4 contained guide 6 of the closure wedge 8 rear side limited by two the locking wedge 8 embracing guide rails 9 of the bottom piece 4.

Der Verschlusskeil 8 ist von einer geöffneten Position, bei welcher Munition 10 axial mit Hilfe eines Ansetzers einer Ladeeinrichtung (nicht dargestellt) in den Ladungsraum 11 des Waffenrohres 2 ladbar ist, in eine teilweise geschlossene Position (dargestellt in Fig.1), bei welcher ein Zurückrutschen der Munition 10 aus dem Ladungsraum 11 durch den Verschlusskeil 8 verhindert wird, in eine geschlossene Position verschiebbar.The closure wedge 8 is movable from an open position, in which ammunition 10 can be loaded axially into the cargo space 11 of the weapon barrel 2 by means of a piecing device of a loading device (not shown), into a partially closed position (shown in FIG Fig.1 ), in which a slipping back of the ammunition 10 from the cargo space 11 is prevented by the shutter wedge 8, displaceable in a closed position.

In der teilweise geschlossenen Position wird der Verschlusskeil 8 von einer Sperreinrichtung 12 blockiert.In the partially closed position of the closure wedge 8 is blocked by a locking device 12.

Die Sperreinrichtung 12 umfasst zwei Haltevorrichtungen 13, welche heckseitig hinter dem Verschlusskeil 8 an den einander zugewandten Stirnseiten 14, 15 der Führungsleisten 9 des Bodenstückes 4 befestigt sind.The locking device 12 comprises two holding devices 13, which rear side behind the closure wedge 8 at the mutually facing end faces 14, 15 of the guide rails 9 of the bottom piece 4 are attached.

Jede Haltevorrichtung 13 besitzt ein bolzenförmiges Sperrelement 16, welches in einer entsprechenden Halteeinrichtung 17 von einer Ruheposition in eine Sperrposition axial verschiebbar gelagert ist. Dabei liegt das Sperrelement 16 in seiner Sperrposition an einer Anschlagsfläche 18 des Verschlusskeiles 8 an (Fig.2).Each holding device 13 has a bolt-shaped blocking element 16 which is mounted axially displaceably in a corresponding holding device 17 from a rest position into a blocking position. In this case, the blocking element 16 is in its locking position on a stop surface 18 of the closure wedge 8 ( Fig.2 ).

Das jeweilige Sperrelement 16 steht mit einer Betätigungseinrichtung 19 der entsprechenden Haltevorrichtung 13 in Wirkverbindung. Diese weisen einen klappenförmigen ersten Schwenkhebel (Betätigungsteil) 20 auf, dessen erstes Ende 21 um eine halteeinrichtungsfeste erste Drehachse 22 schwenkbar ist und durch zwei Rückstellelemente (Federn) 23 in einer Ausgangsstellung gehalten wird (Fig.3). Eine Nut 30 sowie eine Flachsenkbohrung im Halter 17 dienen zur Lagefixierung und Befestigung am Bodenstück 4.The respective blocking element 16 is in operative connection with an actuating device 19 of the corresponding holding device 13. These have a flap-shaped first pivot lever (actuating part) 20, whose first end 21 is pivotable about a holder-fixed first axis of rotation 22 and is held by two return elements (springs) 23 in an initial position ( Figure 3 ). A groove 30 and a counterbore in the holder 17 serve to fix the position and attachment to the bottom piece. 4

Das zweite Ende 24 des ersten Schwenkhebels 20 ragt seitlich in den durch die beiden Führungsleisten 9 des Bodenstückes 4 begrenzten Raum (Fig.1). Im Bereich dieses Endes 24 des ersten Schwenkhebels 20 ist ein zweiter als Schwinge ausgebildeter Schwenkhebel 25 um eine durch den ersten Schwenkhebel 20 gehende zweite Drehachse 26 schwenkbar gelagert, dessen der zweiten Drehachse 26 abgewandtes zweites Ende 27 um eine dritte Drehachse 28 gelenkig mit dem in der axialen Führung der Halteeinrichtung 17 verschiebbar angeordneten Sperrelement 16 verbunden ist.The second end 24 of the first pivot lever 20 projects laterally into the space defined by the two guide rails 9 of the bottom piece 4 ( Fig.1 ). In the area of this end 24 of the first pivot lever 20, a second rocker arm formed as a rocker arm 25 is pivotally mounted about a passing through the first pivot lever 20 second pivot axis 26, the second axis of rotation 26 remote from the second end 27 about a third axis of rotation 28 hinged to the in the axial guide of the holding device 17 slidably disposed locking element 16 is connected.

Beim Ansetzen einer Patrone wird daher das zweite Ende 24 des ersten Schwenkhebels 20 durch den Ansetzer des Ladeautomaten gegen den Druck der Rückstellelemente 23 in eine Betätigungsposition gedrückt und betätigt dabei die Schwinge 25, die ihrerseits das Sperrelement 16 von seiner Ruheposition (Fig.3) in seine Sperrposition (Fig.4) verschiebt.When attaching a cartridge, therefore, the second end 24 of the first pivot lever 20 is pressed by the piecing of the loading machine against the pressure of the return elements 23 in an operating position and actuates the rocker 25, which in turn the blocking element 16 from its rest position ( Figure 3 ) into its blocking position ( Figure 4 ) shifts.

Wie den Fig.2 und 4 direkt entnehmbar ist, sind die Lagen der drei Drehachsen 22, 26 und 28 derart gewählt, dass sie in der Sperrposition des Sperrelementes 16 im wesentlichen auf einer Linie liegen und die Schließkraft des Verschlusskeiles 8, die auf das bolzenförmige Sperrelement 16 wirkt, kein öffnendes Moment auf das Betätigungsteil 20 der Haltevorrichtung 13 bewirkt, sodass der Verschlusskeil 8 zuverlässig in der teilweise geschlossenen Position gehalten wird.Like that Fig.2 and 4 is directly removed, the positions of the three axes of rotation 22, 26 and 28 are selected such that they lie in the blocking position of the blocking element 16 substantially in line and the closing force of the closure wedge 8, which acts on the bolt-shaped blocking element 16, no opening moment on the actuating part 20 of the holding device 13 causes, so that the shutter wedge 8 is reliably held in the partially closed position.

Das bolzenförmige Sperrelement 16 ist auf seiner der Anschlagsfläche 18 des Verschlusskeiles 8 zugewandten Seite 29 abgeflacht und die Anschlagsfläche 18 des Verschlusskeiles 8 heckseitig verjüngend abgeschrägt ausgebildet, wobei die Steigung der abgeschrägten Anschlagsfläche 18 derart bemessen ist, dass keine Selbsthemmung des gegen die Anschlagsfläche 18 gedrückten, abgeflachten, bolzenförmigen Sperrelementes 16 erfolgt.The bolt-shaped blocking element 16 is on its stop surface 18 of the closure wedge Flattened 8 and the stop surface 18 of the closure wedge 8 tapered beveled tapered rear side, wherein the slope of the beveled abutment surface 18 is dimensioned such that no self-locking of the pressed against the abutment surface 18, flattened, bolt-shaped blocking element 16 takes place.

Wird daher nach dem Laden einer Patrone 10 der Ansetzer zurückgefahren, so verbleibt der Verschlusskeil 8 so lange in der in Fig.1 dargestellten, teilweise geschlossenen Position, wie der Ansetzer beim Zurückfahren seitlich gegen den kappenförmigen ersten Schwenkhebel 20 diesen in der Betätigungsposition hält. Sobald der Ansetzer den ersten Schwenkhebel 20 freigibt, drücken die Rückstellelemente 23 das zweite Ende 24 des ersten Schwenkhebels 20 in den zwischen den Führungsleisten 9 befindlichen Raum und die Schwinge 25 zieht das Sperrelement 16 zurück, sodass der Verschlusskeil 8 in seine geschlossene Position von einer nicht dargestellten Schließfeder gedrückt wird. Dabei wird die Rückzugsbewegung des Sperrelementes 16 durch den Verschlusskeil 8 unterstützt, da die Steigung der abgeschrägten Anschlagsfläche 18 des Verschlusskeiles 8 keine Selbsthemmung bewirkt.Therefore, if the piecing is retracted after loading a cartridge 10, the shutter wedge 8 remains in the in Fig.1 illustrated, partially closed position, as the piecing when retracting laterally against the cap-shaped first pivot lever 20 keeps this in the operating position. Once the piecing releases the first pivoting lever 20, the return elements 23 push the second end 24 of the first pivoting lever 20 into the space located between the guide rails 9 and the rocker 25 retracts the blocking element 16 so that the closure wedge 8 does not move to its closed position pressed closing spring is pressed. The return movement of the blocking element 16 is supported by the closure wedge 8, since the slope of the chamfered stop surface 18 of the closure wedge 8 does not cause self-locking.
