Die Erfindung betrifft eine Rohrwaffe mit einem in einer Wiege von einer Ruheposition in eine Rücklaufposition verschiebbar gelagerten Waffenrohr mit Bodenstück, wobei das Bodenstück einen Keilverschluss mit einem quer zur Seelenrohrachse des Waffenrohres von einer geschlossenen in eine geöffnete Stellung verschiebbaren Verschlusskeil umfasst.The invention relates to a gun barrel with a weapon tube slidably mounted in a cradle from a rest position to a return position with bottom piece, wherein the bottom piece comprises a wedge lock with a transverse to the soul tube axis of the barrel from a closed to an open position sliding closure wedge.

Eine derartige Rohrwaffe gemäss dem Oberbegriff des Anspruchs 1 ist beispielsweise aus dem Dokument DE 101 46 423 A1 be kannt. Um bei dieser Rohrwaffe nach einer Schussabgabe den Verschlusskeil automatisch zu öffnen, sodass die Patronenhülse mittels eines Auswerfers ausgeworfen und anschließend eine neue Patrone nachgeladen werden kann, wirkt eine an dem Bodenstück von einer Ausgangs- in eine Betätigungsstellung axial verschiebbare Kolbenstange über Zwischenglieder auf einen mit dem Verschlusskeil verbundenen Öffnerhebel, derart, dass eine Verschiebung der Kolbenstange zum Verschlusskeil hin zu einer Schwenkbewegung des Öffnerhebels und damit zu einem Öffnen des Verschlusskeiles führt.Such a gun according to the preamble of claim 1 is for example from the document DE 101 46 423 A1 known. To automatically open the shutter wedge in this gun after a firing shot, so that the cartridge case ejected by an ejector and then a new cartridge can be reloaded acts on the bottom piece of an output into an actuating position axially displaceable piston rod via intermediate links on with the Closing wedge connected opener lever, such that a displacement of the piston rod to the wedge closure leads to a pivoting movement of the opener lever and thus to an opening of the closure wedge.

Hierzu stehen die Kolbenstange und ein parallel zu der Kolbenstange an dem Bodenstück befestigtes Steuerelement über eine an der Wiege angeordnete Steuereinheit in Wirkverbindung, derart, dass bei einem Vorlauf des Waffenrohres von seiner Rücklauf- in seine Ruheposition die Kolbenstange von der Steuereinheit verschoben und damit auch der Verschlusskeil in seine geöffnete Stellung gebracht wird. Dabei umfasst die Steuereinheit ein an der Wiege der Rohrwaffe befestigtes Gehäuse, welches eine gegen den Druck einer ersten Feder axial zur Mündung des Waffenrohres hin verschiebbare und mit der Kolbenstange fluchtende Schaltstange teilweise umschließt, sowie mindestens ein von dem Steuerelement über eine Steuerstange von einer Sperrstellung in eine Freigabestellung betätigbares, schwenkbares Rastelement, wobei das Rastelement in seiner Sperrstellung formschlüssig in eine Rastnut der Schaltstange eingreift. Außerdem sind die Län-gen der Kolbenstange und der Schaltstange derart gewählt, dass der Verschlusskeil sich bei dem Vorlauf des Waffenrohres durch die axiale Verschiebung dieser Stangen bereits in seine geöffnete Stellung verschoben hat, bevor das Steuerelement auf die Steuerstange wirkt und damit bevor das Rastelement in seine Freigabestellung gelangt.For this purpose, the piston rod and a parallel to the piston rod attached to the bottom piece of control via a arranged on the cradle control unit in operative connection, such that in a flow of the barrel from its return to its rest position, the piston rod moved by the control unit and thus the Closure wedge is brought into its open position. In this case, the control unit comprises a fixed to the cradle of the gun barrel housing which encloses a against the pressure of a first spring axially displaceable towards the mouth of the gun barrel and aligned with the piston rod shift rod, and at least one of the control via a control rod from a locking position in a release position operable, pivotable locking element, wherein the locking element engages positively in its locking position in a locking groove of the shift rod. In addition, the lengths are the piston rod and the shift rod chosen such that the closure wedge has already moved in the lead of the gun barrel by the axial displacement of these rods in its open position before the control acts on the control rod and thus before the locking element passes into its release position.

Ausgehend von der DE 101 46 423 A1 liegt der Erfindung die Aufgabe zugrunde, eine Rohrwaffe anzugeben, bei welcher die Steuereinheit zur Betätigung der auf den Öffnerhebel wirkenden Kolbenstange einen kompakteren Aufbau besitzt, als dieses bei der bekannten Rohrwaffe der Fall ist.Starting from the DE 101 46 423 A1 The invention has for its object to provide a gun barrel, in which the control unit for actuating the force acting on the opener piston rod has a more compact structure, as is the case with the known gun barrel.

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.

Es wird von einer Rohrwaffe mit einem in einer Wiege von einer Ruheposition in eine Rücklaufposition verschiebbar gelagerten Waffenrohr mit Bodenstück ausgegangen, wobei das Bodenstück einen Keilverschluss mit einem quer zur Seelenrohrachse des Waffenrohres von einer geschlossenen in eine geöffnete Stellung verschiebbaren Verschlusskeil umfasst. Am Bodenstück ist eine von einer Ausgangs- in eine Betätigungsstellung axial verschiebbare Kolbenstange angeordnet, die in ihrer Ausgangsstellung auf ihrer der Wiege zugewandten Seite axial vor das Bodenstück bevorzugt hinausragt und die auf ihrer der Wiege abgewandten Seite über Zwischenglieder auf einen mit dem Verschlusskeil verbundenen Öffnerhebel wirkt. Dabei führt eine Verschiebung der Kolbenstange zum Verschlusskeil hin zu einer Schwenkbewegung des Öffnerhebels und damit zu einem Öffnen des Verschlusskeiles. Am Bodenstück ist des Weiteren parallel zu der Kolbenstange ein stangenförmiges Steuerelement fest angeordnet, wobei die Kolbenstange und das Steuerelement über eine an der Wiege angeordnete Steuereinheit in Wirkverbindung stehen, derart, dass bei einem Vorlauf des Waffenrohres von seiner Rücklauf- in seine Ruheposition die Kolbenstange von der Steuereinheit (11) verschoben und damit auch der Verschlusskeil in seine geöffnete Stellung verschoben wird. Die Steuereinheit umfass ein an der Wiege befestigtes Gehäuse, welches eine beispielsweise gegen den Druck einer ersten Feder axial zur Mündung des Waffenrohres hin verschiebbare und mit der Kolbenstange fluchtende Schaltstange teilweise umschließt, sowie mindestens ein von dem Steuerelement von einer Sperrstellung in eine Freigabestellung betätigbares Rastelement, wobei das Rastelement in seiner Sperrstellung in eine Rastnut der Schaltstange eingreift. Dabei sind die Längen der Kolbenstange und der Schaltstange derart gewählt, dass der Verschlusskeil sich bei dem Vorlauf des Waffenrohres durch die axiale Verschiebung dieser Stangen bereits in seine geöffnete Stellung verschoben hat, bevor das Steuerelement das Rastelement in seine Freigabestellung betätigt,It is assumed by a gun barrel with a slidably mounted in a cradle from a rest position to a return barrel gun barrel with bottom piece, the bottom piece includes a wedge lock with a transversely to the soul tube axis of the barrel from a closed to an open position sliding closure wedge. At the bottom of a piece from an initial position into an actuating position axially displaceable piston rod is arranged, which protrudes axially in its initial position on its side facing the cradle axially in front of the bottom piece and which acts on its side facing away from the cradle via intermediate members on an opener lever connected to the closure wedge , In this case, a displacement of the piston rod to the closure wedge leads to a pivoting movement of the opener lever and thus to an opening of the closure wedge. Furthermore, a rod-shaped control element is fixedly arranged parallel to the piston rod at the bottom piece, wherein the piston rod and the control element are operatively connected via a control unit arranged on the cradle, such that the piston rod of., Is returned to its rest position when the weapon barrel advances the control unit (11) moved and thus the shutter wedge is moved to its open position. The control unit comprises a housing attached to the cradle, which encloses a, for example, against the pressure of a first spring axially displaceable towards the mouth of the gun barrel and aligned with the piston rod shift rod, and at least one actuatable by the control of a locking position in a release position latching element, wherein the locking element engages in its blocking position in a locking groove of the shift rod. The lengths of the piston rod and the shift rod are chosen such that the Closing wedge has already moved in the forward flow of the gun barrel by the axial displacement of these rods in its open position, before the control actuates the locking element in its release position,

Die Erfindung beruht nunmehr im Wesentlichen auf dem Gedanken, die Steuerstange und das schwenkbare Rastelement der bekannten Steuereinheit durch eine auf dem Gehäuse der Steuereinheit gegen den Druck einer zweiten Feder axial verschiebbar angeordnete Steuerhülse zu ersetzen, deren innerer Wandbereich eine Steuerkontur aufweist, an der sich in dem Wandbereich des Gehäuses in Führungsausnehmungen radial verschiebbar gelagerte Rastelemente außenseitig abstützen.The invention is based essentially on the idea to replace the control rod and the pivotable locking element of the known control unit by a on the housing of the control unit against the pressure of a second spring axially displaceably arranged control sleeve whose inner wall portion has a control contour on which in the latching elements mounted radially displaceably on the wall region of the housing in guide recesses are supported on the outside.

Vorzugsweise sind mehrere kugel- oder zylinderförmig ausgebildete Rastelemente vorgesehen, welche jeweils in einer eigenen Führungsausnehmung des die Schaltstange umschließenden Gehäuses radial verschiebbar gelagert sind, und in ihrer jeweiligen Sperrstellung in eine ringförmig um die Schaltstange herum laufende Rastnut eingreifen.Preferably, a plurality of ball-shaped or cylindrical locking elements are provided, which are each mounted radially displaceably in a separate guide recess of the housing surrounding the switching rod, and engage in their respective locking position in a ring around the shift rod around running locking groove.

Bei einer vorteilhaften Ausführungsform der Erfindung ist die Steuerhülse mit ihrem dem Bodenstück des Waffenrohres zugewandten Ende axial verschiebbar auf der verschlussseitig aus dem Gehäuse herausragenden Schaltstange und mit ihrem der Wiege zugewandten Ende axial verschiebbar auf einem rohrförmigen Gehäuseteil des Gehäuses gelagert.In an advantageous embodiment of the invention, the control sleeve with its bottom piece of the gun barrel end facing axially displaceable on the closure side protruding from the housing shift rod and its cradle end axially slidably mounted on a tubular housing part of the housing.

Der die Steuerkontur bildende innere Wandbereich der Steuerhülse kann beispielsweise durch einen sich in Richtung auf das Bodenstück erweiternden, im Wesentlichen konischen Wandabschnitt gebildet werden.The inner wall region of the control sleeve forming the control contour can be formed, for example, by a substantially conical wall section widening in the direction of the bottom piece.

Zur Minderung des Aufpralles der Schaltstange auf die Kolbenstange hat es sich als zweckmäßig erwiesen, wenn das dem Bodenstück zugewandte Ende der Schaltstange über einen Stoßdämpfer mit dem restlichen Teil der Schaltstange verbunden ist.To reduce the impact of the shift rod on the piston rod, it has proven to be expedient if the bottom piece facing the end of the shift rod is connected via a shock absorber with the remaining part of the shift rod.

Um ein Öffnen des Keilverschlusses auch in der Ruheposition (Feuerstellung) des Waffenrohres auf einfache Weise zu ermöglichen, ist bei einer bevorzugten Ausführungsform der Erfindung vorgesehen, dass der dem Bodenstück des Waffenrohres abgewandte Gehäuseboden der Steuereinheit axial verschiebbar in dem an der Wiege befestigten Gehäuseteil gelagert und von außen betätigbar ist. Durch eine entsprechende Verschiebung des Gehäusebodens mit Hilfe eines Zusatzantriebes wird dann über die sich über die erste Feder an dem Gehäuseboden abstützende Schaltstange auch die Kolbenstange verschoben und damit der Öffnerhebel des Keilverschlusses betätigt.In order to allow an opening of the wedge closure in the rest position (firing position) of the gun barrel in a simple manner, is provided in a preferred embodiment of the invention that the bottom of the gun barrel facing away from the housing base of the control unit axially slidably mounted in the cradle Housing part stored and operable from the outside. By a corresponding displacement of the housing bottom by means of an additional drive, the piston rod is then displaced via the switching rod which is supported on the housing base via the first spring and thus the opener lever of the wedge lock is actuated.

Die Steuerhülse 21 ist gegen den Druck einer zweiten Feder 24 von einer Ruheposition, bei welcher die Rastelemente 19 von der Steuerkontur 22 beaufschlagt in eine ringförmige Rastnut 25 der Schaltstange 16 gedrückt werden und sich daher in ihren Sperrstellungen befinden (Fig. 4), in eine Freigabeposition verschiebbar, bei der die radiale Fixierung der Rastelemente 19 aufgehoben wird und die Rastelemente aus der Rastnut 25 der Schaltstange 16 heraus in die Steuerhülse 21 verschiebbar sind (Fig. 2).For the radial displacement of the latching elements 19, a control sleeve 21, which is axially displaceable on the cradle-fixed housing part 13 of the control unit 11, is provided with a control wall 22 having an inner wall region 23. The control sleeve 21 is pressed against the pressure of a second spring 24 from a rest position in which the locking elements 19 acted upon by the control contour 22 in an annular locking groove 25 of the shift rod 16 and therefore in their Lock positions are located ( Fig. 4 ), in a release position displaceable, in which the radial fixation of the locking elements 19 is released and the locking elements from the locking groove 25 of the shift rod 16 out in the control sleeve 21 are displaceable ( Fig. 2 ).

Nachfolgend wird näher auf die Funktionsweise der erfindungsgemäßen Rohrwaffe 1 eingegangen. Dabei möge sich die Rohrwaffe 1 zunächst in der in Fig. 1 dargestellten Abfeuerstellung befinden, bei welcher der Verschlusskeil 7 geschlossen ist. In dieser Stellung hat das Steuerelement 10 die Steuerhülse 21 der Steuereinheit 11 gegen den Druck der zweiten Feder 24 zur Mündung des Waffenrohres 3 hin in ihre Freigabeposition verschoben (Fig. 2), sodass die Fixierung der Schaltstange 16 aufgehoben ist und die maximal ausgefahrene Kolbenstange 8 sich in ihrer Ausgangsstellung befindet. Die Schaltstange 16 ist daher in dieser Position der Kolbenstange 8 gegen den Druck der ersten Feder 15 in Richtung Mündung des Waffenrohres 3 verschoben.Below will be discussed in more detail on the operation of the gun barrel 1 according to the invention. It may be the gun 1 first in the in Fig. 1 are shown Abfeuerstellung in which the shutter wedge 7 is closed. In this position, the control element 10 has the control sleeve 21 of the control unit 11 is moved against the pressure of the second spring 24 to the mouth of the gun barrel 3 in its release position ( Fig. 2 ), so that the fixation of the shift rod 16 is canceled and the maximum extended piston rod 8 is in its initial position. The shift rod 16 is therefore displaced in this position of the piston rod 8 against the pressure of the first spring 15 in the direction of the mouth of the gun barrel 3.

Nach Schussabgabe erfolgt der Rücklauf des Waffenrohres 3 in die in den Fig. 3 und 4 wiedergegebene Rücklaufstellung. Dabei bleibt der Verschlusskeil 7 geschlossen und die Kolbenstange 8 verbleibt in ihrer Ausgangsstellung. Die beiden Federn 15, 24 drücken die Schaltstange 16 und die Steuerhülse 21 in ihre Ruhepositionen, sodass die kugelförmigen Rastelemente 19 von der Steuerkontur 22 der Steuerhülse 21 in die ringförmige Rastnut 25 der Schaltstange 16 (das heißt in die Sperrstellungen der Rastelemente) gedrückt werden und diese axial fixiert ist (Fig. 4).After firing the return of the gun barrel 3 in the in the 3 and 4 reproduced return position. The closure wedge 7 remains closed and the piston rod 8 remains in its initial position. The two springs 15, 24 press the shift rod 16 and the control sleeve 21 in their rest positions, so that the spherical locking elements 19 are pressed by the control contour 22 of the control sleeve 21 in the annular locking groove 25 of the shift rod 16 (that is, in the blocking positions of the locking elements) and this is axially fixed ( Fig. 4 ).

Nach Erreichen der Rücklaufposition des Waffenrohres 3 wird das Bodenstück 4 des Waffenrohres 3 durch einen nicht dargestellten Rohrvorholer wieder zum Wiegenrohr 2 hin verschoben (Fig. 5). Dabei trifft die maximal ausgefahrene Kolbenstange 8 auf die in ihrer Ausgangsstellung befindliche und gesperrte Schaltstange 16, sodass die Kolbenstange 8 zum Öffnerhebel 9 hin in ihre Betätigungsstellung verschoben wird, bevor das Steuerelement 10 eine Verschiebung der Steuerhülse 21 in die Freigabeposition bewirkt. Der Verschlusskeil 7 wird durch den sich verschwenkenden Öffnerhebel 9 in seine geöffnete Stellung verschoben und die Patronenhülse der abgefeuerten Patrone ausgeworfen.After reaching the return position of the gun barrel 3, the bottom piece 4 of the gun barrel 3 is moved back to the cradle tube 2 by a pipe recuperator, not shown ( Fig. 5 ). In this case, the maximum extended piston rod 8 hits the locked and disengaged in its initial position shift rod 16, so that the piston rod 8 is moved to the opening lever 9 back to its operating position, before the control 10 causes a displacement of the control sleeve 21 in the release position. The shutter wedge 7 is moved by the pivoting opening lever 9 in its open position and ejected the cartridge case of the fired cartridge.

Anschließend erreicht das Steuerelement 10 die Steuerhülse 21 und verschiebt diese gegen den Druck der zweiten Feder 24 in die Freigabeposition (Fig. 6), sodass die kugelförmigen Rastelemente 19 radial nach außen verschoben werden und die Fixierung der Schaltstange 16 aufgehoben ist. Der Verschlusskeil 7 fällt etwas zurück und wird nun von verschlussseitig angeordneten Auswerfern (nicht dargestellt) in seiner Ladeposition gehalten.Subsequently, the control 10 reaches the control sleeve 21 and moves it against the pressure of the second spring 24 in the release position ( Fig. 6 ), so that the spherical locking elements 19 are moved radially outward and the fixation of the shift rod 16 is repealed. The shutter wedge 7 falls back slightly and is now from Shuttering arranged ejectors (not shown) held in its loading position.

Die Rohrwaffe 1 kann nun geladen werden. Dabei werden die nicht dargestellten Auswerfer beim Einschieben der Rohrwaffe 1 verschwenkt und geben den Verschlusskeil 7 frei, sodass dieser in seine geschlossene Stellung verschoben wird. Die Rohrwaffe 1 ist wiederum abfeuerbereit (Fig. 1 und 2).The gun 1 can now be loaded. The ejectors, not shown, are pivoted when inserting the gun 1 and release the shutter wedge 7 so that it is moved to its closed position. The barrel weapon 1 is again ready to fire ( Fig. 1 and 2 ).

Um ein Öffnen des Keilverschlusses 5 auf einfache Weise auch dann zu ermöglichen, wenn sich die Rohrwaffe 1 in ihrer Abfeuerstellung (Ruheposition des Waffenrohres 3) befindet, ist vorgesehen, dass der sich wiegenrohrseitig an einem Sicherungsring 26 abstützende Gehäuseboden 14 der Steuereinheit 11 gegen den Druck der ersten Feder 15 axial verschiebbar in dem rohrförmigen Gehäuseteil 13 gelagert und von außen betätigbar ist.In order to allow opening of the wedge lock 5 in a simple manner even when the gun 1 is in its Abfeuerstellung (rest position of the gun barrel 3), it is provided that the weighing tube side on a retaining ring 26 supporting the housing bottom 14 of the control unit 11 against the pressure the first spring 15 is axially displaceably mounted in the tubular housing part 13 and operable from the outside.

Durch eine entsprechende Verschiebung des Gehäusebodens 14 (beispielsweise mit Hilfe eines nicht dargestellten Zusatzantriebes) in Richtung der in den Fig. 1 und 2 mit 27 bezeichneten Pfeiles, wird dann über die sich über die erste Feder 15 an dem Gehäuseboden abstützende Schaltstange 16 auch die Kolbenstange 8 verschoben und damit der Öffnerhebel 9 des Keilverschlusses 5 betätigt.By a corresponding displacement of the housing bottom 14 (for example, by means of an auxiliary drive, not shown) in the direction of the in the Fig. 1 and 2 Arrows 27 denoted by 27, then the piston rod 8 is moved over the over the first spring 15 on the housing bottom supporting the shift rod 16 and thus the opener lever 9 of the wedge lock 5 is actuated.

Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So können als Rastelemente statt Kugeln beispielsweise auch Zylinderrollen oder stiftförmige Körper mit entsprechenden abgerundeten Enden etc. verwendet werden. Statt einer ringförmigen (umlaufenden) Rastnut können in die Schaltstange auch einzelne, den Rastelementen gegenüberliegende Rastnuten eingebracht werden.Of course, the invention is not limited to the embodiment described above. For example, cylindrical rollers or pin-shaped bodies with corresponding rounded ends etc. can also be used as latching elements instead of balls. Instead of an annular (circumferential) locking groove can also be introduced into the shift rod and individual, the locking elements opposite locking grooves.
