Abstract

In a barrel firearm, a rear barrel piece (4) and, by means of its actuating device (5), a front barrel piece (3) are pivotable about a trunnion (2). To improve the sealing of the barrel pieces (3, 4) in their coaxial position, there is a closing sleeve (16) which is guided on a thread (15). In the coaxial position of the barrel pieces (3, 4), the actuating device (5) rotates the closing sleeve (16) in such a way that it is pushed axially, together with a sealing ring, over the parting line of the barrel pieces (3, 4). <IMAGE>

Description

Die Erfindung betrifft eine Rohrwaffe mit einem vorderen Rohrstück, das mittels einer Betätigungsvorrichtung um einen Schildzapfen kipp­bar ist, und mit einem hinteren Rohrstück, das ebenfalls um den Schildzapfen schwenkbar ist, wobei die Rohrstücke in ihrer koaxialen Stellung mittels eines Dichtrings an einer Trennstelle ohne ein axiales Verschieben eines der Rohrstücke abgedichtet sind.The invention relates to a tube weapon with a front tube piece which can be tilted by means of an actuating device about a shield pin, and with a rear tube piece which can also be pivoted about the shield pin, the tube pieces in their coaxial position by means of a sealing ring at a separation point without an axial Moving one of the pipe pieces are sealed.

Eine derartige Rohrwaffe ist in der DE-OS 34 40 467 beschrieben. Zum Laden der Rohrwaffe wird das vordere Rohrstück gegenüber dem hinteren Rohrstück in eine horizontale Stellung verschwenkt. Nach dem Einschieben einer Munition wird das vordere Rohrstück vor das hintere Rohrstück geschwenkt. Die Munition fällt dann auf einen Schlagstift des hinteren Rohrstückes. Diese Rohrwaffe eignet sich als Steilfeuerwaffe. Der Elevationswinkel wird durch gemeinsames Verschwenken der beiden Rohrstücke um den Schildzapfen eingestellt.Such a gun is described in DE-OS 34 40 467. To load the barrel weapon, the front barrel section is pivoted into a horizontal position relative to the rear barrel section. After insertion of ammunition, the front pipe section is pivoted in front of the rear pipe section. The ammunition then falls on a striking pin of the rear pipe section. This barrel weapon is suitable as a firearm. The elevation angle is adjusted by swiveling the two pipe sections together around the shield spigot.

In der DE-OS 22 38 345 ist ein Granatwerfer beschrieben, bei dem das vordere Rohrstück, abgeschwenkt vom hinteren Rohrstück, von unten zu laden ist. Um die beiden Rohrstücke an der Trennstelle abzudichten, wird das vordere Rohrstück axial an das hintere Rohr­stück geschoben. Dies erfolgt mit der gleichen Betätigungsvorrich­tung, mit der auch das vordere Rohrstück kippbar ist. Zur Verriege­lung der beiden Rohrstücke ist eine Verriegelungshülse vorgesehen.DE-OS 22 38 345 describes a grenade launcher in which the front pipe section, pivoted away from the rear pipe section, can be loaded from below. In order to seal the two pipe sections at the point of separation, the front pipe section is pushed axially onto the rear pipe section. This is done with the same actuating device with which the front pipe section can be tilted. A locking sleeve is provided to lock the two pipe pieces.

Dies weist einen Munitionsanschlag auf, der ein vorzeitiges Hinein­gleiten der Munition in das hintere Rohrstück verhindert.This has an ammunition stop, which prevents premature sliding of the ammunition into the rear pipe section.

Aufgabe der Erfindung ist es, eine Rohrwaffe der eingangs genann­ten Art vorzuschlagen, bei der die Abdichtung der Rohrstücke verbes­sert ist.The object of the invention is to propose a tube weapon of the type mentioned, in which the sealing of the tube pieces is improved.

Erfindungsgemäß ist obige Aufgabe bei einer Rohrwaffe der eingangs genannten Art dadurch gelöst, daß eine Verschlußhülse vorgesehen ist, die an einem Gewinde geführt ist, und daß in der koaxialen Stellung der Rohrstücke die Betätigungsvorrichtung die Verschluß­hülse dreht, die sich dabei zusammen mit dem in ihr angeordneten Dichtring axial über die Trennstelle der Rohrstücke schiebt.According to the invention, the above object is achieved in the case of a tubular weapon of the type mentioned at the outset in that a closure sleeve is provided which is guided on a thread, and in that in the coaxial position of the tube pieces the actuating device rotates the closure sleeve, which rotates together with that arranged in it Axial sealing ring pushes over the separation point of the pipe sections.

Die über die Trennstelle geschobene Verschlußhülse sichert einer­seits die koaxiale Ausrichtung der Rohrstücke, was Voraussetzung für eine sichere Abdichtung ist. Andererseits verhindert der von der Verschlußhülse über die Trennstelle geschobene Dichtring einen Gasaustritt beim Schuß. Eine axiale Verriegelung der Rohrstücke gegeneinander erfolgt durch die Verschlußhülse nicht. Das hintere Rohr ist im Rohrhalter axialbeweglich geführt.The sealing sleeve pushed over the separation point ensures the coaxial alignment of the pipe sections, which is a prerequisite for a secure seal. On the other hand, the sealing ring pushed by the breech over the separation point prevents gas escaping when the shot is fired. The sealing sleeve does not axially lock the pipe sections against one another. The rear tube is guided axially in the tube holder.

Ein weiterer Vorteil der Erfindung besteht darin, daß mit der glei­chen Betätigungsvorrichtung, mit der das vordere Rohrstück kipp­bar ist, auch die Verschlußhülse durch ihre Gewindeführung über die Trennstelle geschoben wird.Another advantage of the invention is that, with the same actuating device with which the front pipe section can be tilted, the closure sleeve is pushed over the separation point by its thread guide.

Vorzugsweise ist das Gewinde, an dem die Verschlußhülse geführt ist, am hinteren Rohrstück angeordnet und die Verschlußhülse schiebt den Dichtring über das vordere Rohrstück. Das Gewinde selbst trägt dabei zur Abdichtung bei. Bei vorgeschobener Verschlußhülse liegt die Trennstelle der beiden Rohrstücke zwischen dem Gewinde und dem Dicht­ring. Es wäre jedoch auch möglich, an der Verschlußhülse zwei Dicht­ringe vorzusehen, wobei dann in der vorgeschobenen Stellung der Verschlußhülse die Trennstelle zwischen den beiden Dichtringen läge.The thread on which the closure sleeve is guided is preferably arranged on the rear pipe section and the closure sleeve pushes the sealing ring over the front pipe section. The thread itself contributes to the sealing. When the sealing sleeve is pushed forward, the Separation point of the two pipe sections between the thread and the sealing ring. However, it would also be possible to provide two sealing rings on the sealing sleeve, the separating point between the two sealing rings then being in the advanced position of the sealing sleeve.

Zum Antrieb der Verschlußhülse weist diese in Ausgestaltung der Erfindung einen Zahnkranz auf, in den ein erstes Zahngetriebe ein­greift, welchesvon der Betätigungsvorrichtung antreibbar ist. Damit ist das Drehen der Verschlußhülse durch einen einfachen Schwenkhebel der Betätigungsvorrichtung möglich.To drive the closure sleeve, in the embodiment of the invention, this has a toothed ring, into which a first toothed gear engages, which can be driven by the actuating device. This allows the locking sleeve to be rotated by a simple pivoting lever of the actuating device.

In Weiterbildung der Erfindung weist die Betätigungsvorrichtung ein zweites Zahngetriebe auf, mit welchem das vordere Rohrstück kippbar ist. Das erste Zahngetriebe ist gesperrt, wenn das zweite Zahngetriebe wirksam ist. Das zweite Zahngetriebe ist gesperrt, wenn das erste Zahngetriebe wirksam ist. Dadurch ist sichergestellt, daß die Verschlußhülse erst dann verschoben wird, wenn die Rohr­stücke koaxial ausgerichtet sind. Andererseits ist dadurch auch sichergestellt, daß bei der umgekehrten Betätigung der Betätigungs­vorrichtung die Verschlußhülse zunächst zurückgezogen wird und danach das Kippen des vorderen Rohrstückes erfolgt.In a further development of the invention, the actuating device has a second toothed gear with which the front tube piece can be tilted. The first toothed gear is locked when the second toothed gear is active. The second gear is locked when the first gear is in effect. This ensures that the closure sleeve is not moved until the pipe pieces are aligned coaxially. On the other hand, this also ensures that when the actuating device is actuated in reverse, the closure sleeve is first withdrawn and then the front tube piece is tilted.

In bevorzugter Ausgestaltung der Erfindung ist im vorderen Rohrstück ein Munitionsanschlag angeordnet, der gegen Ende der Verschiebung der Verschlußhülse über die Trennstelle der Rohrstücke aus dem vor­deren Rohrstück schwenkt. Dadurch ist gewährleistet, daß die Muni­tion erst dann in das hintere Rohrstück gleitet und ausgeschossen wird, wenn die Abdichtung erfolgt ist.In a preferred embodiment of the invention, an ammunition stop is arranged in the front pipe section, which pivots towards the end of the displacement of the closure sleeve over the separation point of the pipe sections from the front pipe section. This ensures that the ammunition only slides into the rear pipe section and is fired when the seal has been made.

Vorzugsweise schwenkt die Verschlußhülse selbst bei ihrem Vorschieben über die Trennstelle den Munitionsanschlag über die Schubstange aus dem vorderen Rohrstück. Dadurch erübrigt es sich, eine besondere Kopplung zwischen der Betätigungsvorrichtung und dem Munitionsan­schlag vorzusehen.The closure sleeve preferably pivots the ammunition stop over the push rod even when it is pushed forward over the separation point from the front pipe section. This makes it unnecessary to provide a special coupling between the actuating device and the ammunition stop.

In weiterer Ausgestaltung der Erfindung weist die Betätigungsvor­richtung eine Rasteinrichtung auf, die nach dem Vorschieben der Verschlußhülse die Betätigungsvorrichtung sperrt. Die Rasteinrichtung verhindert, daß nach dem Eingleiten der Munition in das hintere Rohrstück die Betätigungsvorrichtung in Gegenrichtung betätigt werden kann. Das Auslösen der Rasteinrichtung erfolgt nach dem Abschluß der Munition. Die Rasteinrichtung kann manuell oder auch durch den Gasdruck des Schusses freigegeben werden.In a further embodiment of the invention, the actuating device has a latching device which blocks the actuating device after the closure sleeve has been pushed forward. The latching device prevents the actuating device from being able to be actuated in the opposite direction after the ammunition has slid into the rear tube piece. The locking device is triggered after the ammunition has been completed. The locking device can be released manually or by the gas pressure of the shot.

Fig. 4).An ammunition stop (13) = (40) is pivotally mounted about an axis (41) on the front pipe section (3). A push rod (43), which is loaded by a spring (44), engages on a pin (42) of the stop member (40). The pull rod (43) is connected to a slide (45) which can be acted upon by the cap (18) of the closure sleeve (16) (cf. FIG. 4).

Die Funktionsweise der beschriebenen Einrichtung ist etwa folgende:The functionality of the described device is approximately as follows:

In der Ladestellung nach Figur 1 und 2 greifen die Zähne (31) des zweiten Zahnsegmentes (27) in die Zahnlücken (30) ein. Die Sperrnasen (33) des Zahnsegments (23) liegen an der Sperrfläche (32) an. Die Rastklinke (37) ruht auf dem Kopf des Zahnes (29). Nach dem Einschub eines Geschosses aus der Ladeschale (10) in das Rohrstück (3) wird der Schwenkhebel (26) im Uhrzeigersinn (U) betätigt. Dabei wird über den Eingriff der Zähne (31) in die Zahnlücken (30) das vordere Rohrstück (4) verschwenkt. Die Rastnasen (33) des Zahnsegmentes (23) gleiten an der Sperrfläche (32), so daß sich das Zahnsegment (23) nicht bewegt und damit auch die Verschlußhülse (16) stillsteht.In the loading position according to FIGS. 1 and 2, the teeth (31) of the second tooth segment (27) engage in the tooth gaps (30). The locking lugs (33) of the toothed segment (23) rest on the locking surface (32). The latch (37) rests on the head of the tooth (29). After insertion of a projectile from the charging cradle (10) into the pipe section (3), the swivel lever (26) is actuated clockwise (U). The front pipe section (4) is pivoted via the engagement of the teeth (31) in the tooth gaps (30). The locking lugs (33) of the toothed segment (23) slide on the locking surface (32), so that the toothed segment (23) does not move and the closure sleeve (16) thus also stands still.

Steht das vordere Rohrstück (3) koaxial zum hinteren Rohrstück (4), dann liegen die Sperrnasen (34) an der Sperrfläche (32) an.If the front pipe section (3) is coaxial with the rear pipe section (4), then the locking lugs (34) rest on the locking surface (32).

Bei der weiteren Bewegung des Schwenkhebels (26) greifen die Zähne (29) in die Zahnlücken (28), so daß nun das Zahnsegment (23) ver­schwenkt wird. Dadurch wird über das Zahngetriebe (22) die Verschluß­hülse (16) längs des Gewindes (15) gedreht, so daß sie sich axial über die Trennstelle zwischen dem vorderen Rohrstück (3) und dem hinteren Rohrstück (4) schiebt. Der Dichtring (19) wid dabei über das vordere Rohrstück (3) geschoben. Die Rastklinke (37) rastet auf die erste Stufe (35), so daß der Schwenkhebel (26) nicht mehr ohne weiteres zurückbewegt werden kann.As the pivot lever (26) moves further, the teeth (29) engage in the tooth gaps (28) so that the toothed segment (23) is now pivoted. As a result, the closure sleeve (16) is rotated along the thread (15) via the toothed gear (22), so that it pushes axially over the separation point between the front pipe section (3) and the rear pipe section (4). The sealing ring (19) is pushed over the front pipe section (3). The locking pawl (37) snaps onto the first step (35) so that the swivel lever (26) can no longer be moved back easily.

Bei der weiteren Bewegung des Schwenkhebels (26) in Uhrzeigerrichtung (U) trifft die Verschlußhülse (16) mit der Kappe (18) auf die Schub­stange (43), so daß diese das Anschlagglied (13) aus dem vorderen Rohrstück (3) herausschwenkt. Zuvor hat die Rastklinke (37) die Sperrstufe (36) erreicht. Der Schwenkhebel (26) steht in seiner Endstellung durch Anschlag der Kante (x) an das Rad (25) und die Munition (11) gleitet in das hintere Rohrstück (4) (vgl. Figur 3,4).When the swivel lever (26) moves further in the clockwise direction (U), the closure sleeve (16) with the cap (18) hits the push rod (43) so that it swings the stop member (13) out of the front pipe section (3). The latch (37) has previously reached the locking step (36). The pivot lever (26) is in its end position by abutting the edge (x) on the wheel (25) and the ammunition (11) slides into the rear pipe section (4) (cf. FIG. 3, 4).

Soll dann nach dem Schuß die Rückstellung erfolgen, ist mittels des Griffgliedes (39) die Rastklinke (37) von der Stufe (36) zu lösen. Danach kann durch eine Bewegung des Schwenkhebels (26) entgegen dem Uhrzeigersinn (U) das vordere Rohrstück (3) in seine Ladestellung bewegt werden. Dabei wird zunächst die Verschlußhülse (16) über die Trennstelle zwischen den beiden Rohrstücken (3,4) zurückgezo­gen, weil die Zähne (29) in die Zahnlücken (28) eingreifen, so daß die Verschlußhülse (16) am Gewinde (15) zurückgedreht wird. Durch das Zurückziehen der Verschlußhülse (16) wird das Anschlagglied (13) mittels der Feder (44) wieder in diejenige Stellung gebracht, in der es eine Munition (11) nicht unmittelbar in das hintere Rohr­stück (4) herausfallen läßt. Anschließend greifen die Zähne (31) in die Zahnlücken (30) ein, so daß das vordere Rohrstück (3) vom hinteren Rohrstück (4) abgekippt wird.If the reset should then take place after the shot, the latch (37) must be released from the step (36) by means of the handle member (39). Then you can counteract by moving the pivot lever (26) clockwise (U) the front pipe section (3) can be moved into its loading position. First, the closure sleeve (16) is withdrawn via the separation point between the two pipe sections (3, 4) because the teeth (29) engage in the tooth gaps (28) so that the closure sleeve (16) on the thread (15) is turned back . By retracting the closure sleeve (16), the stop member (13) is brought back into the position by means of the spring (44) in which it does not allow ammunition (11) to fall out directly into the rear pipe section (4). Then the teeth (31) engage in the tooth gaps (30) so that the front pipe section (3) is tipped over from the rear pipe section (4).
