Abstract

A firearm including a barrel holder for accommodating interchangeable barrels. A breechblock housing, connected to a stock, includes in a forward zone thereof, a recess having an abutment surface for absorbing recoil forces, with the barrel including a tubular member fixedly connected to a rear end thereof and including an extension fitting into the recess. The tubular member has a relatively large axial length and extends forwardly from a locking mechanism beyond a cartridge chamber of the firearm. The extension is provided at the rear end of the tubular member, and the abutment surface has an undercut portion partially extending over the extension from above. A downwardly projecting second extension is provided at the front end of the tubular member, with the second extension including a locking bolt recess. The breechblock housing extends up to a zone of the second extension and carries, at that location, a locked bolt cooperating with the locked bolt recess.

Description

Die Erfindung betrifft ein Gewehr mit einer Laufhalterung für Wechselläufe und einem mit einem Schaft verbundenen Verschlußgehäuse, wobei das hintere Laufende in einem den Lauf umschließenden Hülsenteil steckt und an dem Hülsenteil ein zum Schaft hinweisender Ansatz vorhanden ist, durch den Lauf und Schaft wiederlösbar verbindbar sind, und bei dem die Kammer eines Zylinderverschlusses in eine Verriegelung am Laufende eingreift.The invention relates to a rifle with a barrel holder for exchangeable barrels and a breech housing connected to a barrel, the rear barrel end being in a sleeve part enclosing the barrel and on the barrel part an attachment pointing towards the barrel is present, through which barrel and barrel can be releasably connected, and in which the chamber of a cylinder lock engages in a locking mechanism at the barrel end.

Bei einem derartigen bekannten Gewehr mit Laufhalterung für Wechselläufe (DE-A-3 248 620) weist das Verschlußgehäuse eine Quernut auf, in die der Ansatz des Hülsenteiles eingreift. Als weiteres Befestigungsteil ist eine Schraube vorgesehen, die in eine Querbohrung des Verschlußgehäuses eingeschoben und in ein im Ansatz vorgesehenes Gewinde eingeschraubt wird. Durch diese Schraube soll der Ansatz senkrecht zur Laufachse auf dem Nutboden festgespannt werden. Bei diesem bekannten Gewehr kann die Verbindung zwischen dem Lauf und dem Verschlußgehäuse zwar relativ einfach, jedoch immer nur mit einem Schraubenschlüssel (Innensechskantschlüssel) gelöst bzw. wieder hergestellt werden. Das Lösen bzw. Anziehen der Schraube erfordert einen gewissen Zeitaufwand. Wird die Schraube nicht sehr sorgfältig und sehr fest angezogen, so besteht die Gefahr, daß sich .die Verbindung zwischen Hülsenteil und Verschlußgehäuse bei Abgabe mehrerer Schüsse lockert. Des weiteren können die Schraube und auch der Schraubenschlüssel leicht verloren gehen. Dadurch, daß alle Verbindungsteile zwischen dem Hülsenteil und dem Verschlußgehäuse, also der Ansatz, die Nut und die Schraube, auf verhältnismäßig kurzer axialer Länge und an der gleichen Stelle ineinandergreifen, wird auch keine besonders stabile Verbindung zwischen beiden Teilen geschaffen.In such a known rifle with barrel holder for exchangeable barrels (DE-A-3 248 620), the breech housing has a transverse groove in which the shoulder of the sleeve part engages. As a further fastening part, a screw is provided, which is inserted into a transverse bore of the closure housing and screwed into a thread provided in the shoulder. With this screw, the shoulder is to be clamped onto the groove base perpendicular to the barrel axis. In this known rifle, the connection between the barrel and the breech housing can be released or re-established relatively easily, but only with a wrench (Allen key). Loosening or tightening the screw takes a certain amount of time. If the screw is not tightened very carefully and very firmly, there is a risk that the connection between the sleeve part and the breech housing becomes loose when several shots are fired. Furthermore, the screw and the wrench can easily get lost. The fact that all the connecting parts between the sleeve part and the closure housing, that is, the shoulder, the groove and the screw, mesh with one another over a relatively short axial length and at the same point, does not create a particularly stable connection between the two parts.

Bei einem in der DE-C-323971 beschriebenen Rohrrücklaufgeschütz trägt ein Schlitten das Rohr auf seiner ganzen Breite. Ein Repetiervorgang ist nicht möglich. Das vordere Abstützlager ist direkt am Lauf befestigt, wodurch Schwingungen des Laufes behindert sind. Der Lauf ist mittels eines Bajonettverschlusses in den Mantel hineingedreht. Sowohl Lauf als auch Mantel sind mit dem Schlitten verbunden, also werkstoffmäßig und funktionell verschiedene Teile. Bei einem heiß gewordenen Rohr treten thermische Spannungen auf. Eine präzise Lauflagerung ist dadurch sehr in Frage gestellt.In a tube return gun described in DE-C-323971, a carriage carries the tube over its entire width. A repeating process is not possible. The front support bearing is attached directly to the barrel, which prevents the barrel from vibrating. The barrel is screwed into the jacket using a bayonet catch. Both the barrel and the jacket are connected to the slide, i.e. different parts in terms of material and function. When a pipe has become hot, thermal stresses occur. Precise barrel positioning is therefore very much in question.

Bei der in der FR-E-25 739 beschriebenen Pistole ist das Rohr nur über einen Fortsatz am Lauf eingehängt. Eine Hülse ist ebenso wenig vorhanden wie ein Freiraum für ein Repetiersystem.In the pistol described in FR-E-25 739, the tube is only attached to the barrel via an extension. A sleeve is just as little available as there is free space for a repeating system.

Bei der FR-A-507219 ist eine Laufentnahme nur in Laufrichtung möglich. Die Lauflagerung ist nicht ausreichend präzise ; es ist nicht erkennbar, wie bei dieser Büchse eine Repetiereinrichtung angebracht sein müßte. Es sind keine Gegenlager und keine Keilverspannung vorhanden, so daß ein Anzug nach einem Verschleiß nicht möglich ist.The FR-A-507219 can only be removed in the direction of travel. The barrel bearing is not sufficiently precise; it is not clear how a repeating device should be attached to this bush. There are no counter bearings and no wedge bracing so that tightening after wear is not possible.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Gewehr mit einer Laufhalterung für Wechselläufe der eingangs erwähnten Art zu schaffen, bei dem die Verbindung zwischen dem Hülsenteil und dem Verschlußgehäuse besonders stabil und exakt sowie ohne jegliches Werkzeug und ohne die Gefahr des Verlierens von Verbindungsteilen rasch lösbar bzw. wieder herstellbar ist.The invention is therefore based on the object to provide a rifle with a barrel holder for interchangeable barrels of the type mentioned, in which the connection between the sleeve part and the breech housing is particularly stable and precise and can be released quickly without any tools and without the risk of losing connecting parts or can be restored.

Die Lösung dieser Aufgabe besteht nach der Erfindung darin, daß an dem Hülsenteil zwei in axialer Richtung ausreichend weit auseinander liegende Ansätze vorhanden sind, und zwar ein hinten an dem Hülsenteil angebrachter Ansatz, bestehend aus zwei seitlich an dem Hülsenteil angebrachten Elementen, die sich an gekrümmten Widerlagerflächen an dem Verschlußgehäuse abstützen, wobei durch Überschneidungen am Verschlußgehäuse ein unmittelbares Abheben des Hülsenteiles vom Verschlußgehäuse verhindert ist, und ein vorne an der Hülse angebrachter vorderer Ansatz, der eine Riegelausnehmung aufweist, und das Verschlußgehäuse bis in den Bereich des vorderen Ansatzes verlängert ist und dort einen mit der Riegelausnehmung zusammenwirkenden Riegel trägt.The solution to this problem is according to the invention is that there are two approaches sufficiently far apart in the axial direction on the sleeve part, namely a rear attached to the sleeve part, consisting of two laterally attached elements on the sleeve part, which are curved Support abutment surfaces on the breech housing, with overlaps on the breech housing preventing a direct lifting of the sleeve part from the breech housing, and a front attachment attached to the front of the sleeve, which has a locking recess, and the breech housing is extended to the area of the front attachment and there carries a latch cooperating with the latch recess.

Diese Ausgestaltung des Gewehrs ermöglicht ein rasches Lösen und Wiederverbinden des Laufes mit dem Verschlußgehäuse ohne jegliches Werkzeug. Zum Lösen des Laufes wird lediglich der Riegel aus seiner Sperrstellung in seine Freigabestellung gedrückt, worauf der vordere Teil des Laufes gegenüber dem Verschlußgehäuse und dem Schaft hochgeschwenkt werden kann. Nach etwa 20 bis 30° Schwenkwinkel kann der hintere Ansatz herausgezogen werden. Zur Montage wird umgekehrt der hintere Ansatz in die Ausnehmung eingesetzt, so daß sein hinteres Ende an der Widerlagerfläche der Ausnehmung anliegt. Das vordere Ende des Laufes wird nunmehr gegenüber dem Verschlußgehäuse und dem Schaft um etwa 20 bis 30° nach unten geschwenkt, wobei der vordere Ansatz in den Bereich des Riegels gelangt. Es braucht dann nur noch der Riegel in seine Sperrstellung gedrückt werden oder ein federbelasteter Riegel rastet selbsttätig in der Riegelausnehmung des vorderen Ansatzes ein. Die Montage ist damit beendet. Da alle Verbindungsteile fest mit dem Lauf bzw. dem Verschlußgehäuse verbunden sind und auch kein Werkzeug erforderlich ist, besteht nicht die Gefahr, daß irgendwelche zur Herstellung der Verbindung erforderlichen Teile verloren gehen. Die rasche Montage und Lösbarkeit ermöglicht es nicht nur einen Lauf gegen einen Lauf anderen Kalibers auszutauschen, sondern der Lauf kann zu Transport-, Aufbewahrungs- und Reinigungszwecken jeweils leicht vom Verschlußgehäuse und den übrigen Schaft getrennt werden. Da das Hülsenteil eine verhältnismäßig große axiale Länge auf weist und an seinen beiden Enden Ansätze vorgesehen sind, die zur Verbindung mit dem. Verschlußgehäuse dienen, wird auch eine sehr stabile und exakte Verbindung zwischen dem Lauf und dem Verschlußgehäuse geschaffen, die eine hohe Treffgenauigkeit auch unmittelbar nach der Verbindung beider Teile sicherstellt. Der große axiale Abstand der beiden Ansätze und der mit ihnen zusammenwirkenden Teile des Verschlußgehäuses gibt dem Lauf größtmögliche Richtungsstabilität. Ferner ermöglicht das verhältnismäßig lange Hülsenteil die Anbringung eines ebenfalls verhältnismäßig langen Aufnahmeprismas zur Montage eines Zielfemrohres, welches Zielfernrohre verschiedener Fabrikate und der verschiedensten Längen aufnehmen kann. Das Zielfernrohr kann beim Lösen des Laufes vom Verschlußgehäuse mit dem Lauf verbunden bleiben.This design of the rifle enables the barrel to be released and reconnected quickly without any tools. To release the barrel, only the bolt is pressed out of its locked position into its release position, whereupon the front part of the barrel can be swiveled up relative to the breech housing and the shaft. The rear extension can be pulled out after a swivel angle of about 20 to 30 °. For assembly, conversely, the rear extension is inserted into the recess so that its rear end rests on the abutment surface of the recess. The front end of the barrel is now pivoted downward by about 20 to 30 ° with respect to the breech housing and the shaft, the front attachment reaching the area of the bolt. It then only needs to be pressed into its locking position or a spring-loaded latch automatically engages in the latch recess of the front extension. The assembly is now complete. Since all the connecting parts are firmly connected to the barrel or the breech housing and no tools are required, there is no risk that any parts required to make the connection will be lost. The quick assembly and detachability not only make it possible to replace a barrel with a barrel of a different caliber, but the barrel can be easily separated from the breech housing and the remaining shaft for transport, storage and cleaning purposes. Since the sleeve part has a relatively large axial length ge on and approaches are provided at both ends, which for connection to the. Lock housing serve, a very stable and exact connection between the barrel and the lock housing is created, which ensures high accuracy even immediately after connecting the two parts. The large axial distance between the two lugs and the parts of the breech housing interacting with them gives the barrel the greatest possible directional stability. Furthermore, the relatively long sleeve part enables the attachment of a likewise relatively long receiving prism for mounting a telescopic sight, which can accommodate telescopic sights of various makes and of various lengths. The rifle scope can remain connected to the barrel when the barrel is detached from the breech housing.

Eine besonders vorteilhafte Ausgestaltung der Erfindung besteht darin, daß der Lauf an seinem hinteren Laufende einen an den Lauf angearbeiteten Verschlußkopf mit mehreren radial nach innen ragenden mit der Kammer zusammenwirkenden Verriegelungsvorsprüngen aufweist, daß der Lauf vor dem Verschlußkopf im vorderen Bereich des Patronenlagers einen kleineren Durchmesser aufweist als der Verschlußkopf, daß der Lauf von hinten in eine Längsbohrung des Hülsenteiles mit seinem im Durchmesser kleineren Teil-eingeschoben und mit dem Hülsenteil verlötet oder verklebt ist. Durch diese Ausgestaltung wird die Herstellung des Laufes und des Hülsenteiles vereinfacht. Der Lauf ist nämlich im wesentlichen nur ein Drehteil. Das Hülsenteil kann, da es bei dieser Ausgestaltung keinen Teil des Zylinderverschlusses bildet, als Feingußteil hergestellt werden und bedarf keiner Nachbearbeitung. Im übrigen kann dann das Hülsenteil mit Läufen unterschiedlichen Kalibers verbunden werden. Der Lauf kann im Bereich vor dem Verschlußkopf einen verhältnismäßig kleinen Durchmesser aufweisen, wodurch auch das Hülsenteil in seinem Außendurchmesser kleiner wird und das Gesamtgewicht des Gewehrs verringert wird.A particularly advantageous embodiment of the invention consists in the fact that the barrel at its rear barrel end has a breech head worked on the barrel with several radially inwardly projecting locking projections that cooperate with the chamber, that the barrel in front of the breech head has a smaller diameter in the front region of the cartridge chamber than the breech head, that the barrel is inserted from behind into a longitudinal bore of the sleeve part with its smaller part in diameter and soldered or glued to the sleeve part. This configuration simplifies the manufacture of the barrel and the sleeve part. The barrel is essentially just a turned part. The sleeve part, since it does not form part of the cylinder closure in this embodiment, can be produced as an investment casting and requires no reworking. Otherwise, the sleeve part can then be connected to barrels of different calibres. The barrel can have a relatively small diameter in the area in front of the breech head, as a result of which the sleeve part also has a smaller outer diameter and the overall weight of the rifle is reduced.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den übrigen Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the remaining subclaims.

Die Erfindung wird in folgendem anhand von mehreren in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Es zeigen :

The invention is explained in more detail below with reference to several exemplary embodiments shown in the drawing. Show it :
  • 1 is a side view of a first embodiment, partly in section,
  • 2 shows a longitudinal section along the line 11-11 of FIG. 1,
  • 3 shows a cross section along the line 111-111 of FIG. 1,
  • Fig. 4 shows a second embodiment in longitudinal section.

Das Verschlußgehäuse 1 ist mittels der Schrauben 2 mit dem Schaft 3 verbunden. Am Verschlußgehäuse 1 ist ein Gehäuseteil 4, welches die Kammer 5 mit den Verriegelungsvorsprüngen 6 trägt, in Richtung der Laufachse A verschiebbar geführt. Das Gehäuseteil 4 weist zu diesem Zweck zwei Führungsleisten 7, 8 auf, die in zwei nach oben offenen Führungsnuten 9 des Verschlußgehäuses 1 verschiebbar sind.The breech housing 1 is connected to the shaft 3 by means of the screws 2. On the closure housing 1, a housing part 4, which carries the chamber 5 with the locking projections 6, is displaceably guided in the direction of the barrel axis A. For this purpose, the housing part 4 has two guide strips 7, 8, which are displaceable in two upwardly open guide grooves 9 of the closure housing 1.

Es ist ferner ein Hülsenteil 10 vorgesehen, welches eine Längsbohrung 11 aufweist. Das Hülsenteil 10 ist an seinem hinteren Ende mit einem ersten Ansatz 12 und an seinem vorderen Ende mit einem zweiten Ansatz 13 versehen. Um Platz für einen Magazinschacht 14 zu schaffen und die Entnahme von nichtdargestellten Patronen aus dem Magazinschacht zu ermöglichen, weist der erste Ansatz 12 eine sich in Richtung der Laufachse A erstreckende Aussparung 15 auf. Durch diese Aussparung verlaufen auch die beiden Führungsschienen 7, 8. Der Lauf 16 weist an seinem hinteren Ende einen angearbeiteten, d. h. mit dem Lauf aus einem Stück bestehenden Verschlußkopf 16a auf, der mit mehreren radial nach innen ragenden Verriegelungsvorsprüngen 17 versehen ist. Diese Verriegelungsvorsprünge 17 arbeiten mit den Verriegelungswarzen 6 der Kammer 5 nach Art eines Bajonettverschlusses zusammen. Vor dem Verschlußkopf 16a weist der Lauf 16 im Bereich des Patronenlagers ein zylindrisches Teil 16b auf, dessen Durchmesser D2 kleiner ist als der Durchmesser D1 des Verschlußkopfes 16a. Der Lauf 16 ist von hinten in die Längsbohrung 11 eingesteckt und mit dem Hülsenteil 10 zweckmäßig verlötet oder ggf. auch verklebt. In letzterem Fall kann-aus Sicherheitsgründen ein nicht dargestellter Querstift vorgesehen sein, der teilweise in das Hülsenteil 10 und teilweise in das Teil 16b des Laufes 16 eingreift.A sleeve part 10 is also provided, which has a longitudinal bore 11. The sleeve part 10 is provided with a first attachment 12 at its rear end and with a second attachment 13 at its front end. In order to make room for a magazine shaft 14 and to enable cartridges (not shown) to be removed from the magazine shaft, the first attachment 12 has a recess 15 which extends in the direction of the barrel axis A. The two guide rails 7, 8 also run through this recess. The barrel 16 has a machined, ie. H. with the barrel made of one piece locking head 16a, which is provided with a plurality of radially inwardly projecting locking projections 17. These locking projections 17 work with the locking lugs 6 of the chamber 5 in the manner of a bayonet lock. In front of the closure head 16a, the barrel 16 has a cylindrical part 16b in the region of the cartridge chamber, the diameter D2 of which is smaller than the diameter D1 of the closure head 16a. The barrel 16 is inserted from the rear into the longitudinal bore 11 and expediently soldered or possibly also glued to the sleeve part 10. In the latter case, a cross pin (not shown) can be provided for safety reasons, which engages partly in the sleeve part 10 and partly in the part 16 b of the barrel 16.

Das Hülsenteil 10 weist in axialer Richtung eine größere Länge L auf, die mindestens dreimal so groß, wie der vom Hülsenteil umschlossene Durchmesser D2 des Laufteiles 16b sein sollte. Der Ansatz 12 erstreckt sich vom Hülsenteil 10 nach unten und auch nach hinten bis zum hinteren Ende des Verschlußkopfes 16a.The sleeve part 10 has a greater length L in the axial direction, which should be at least three times as large as the diameter D2 of the barrel part 16b enclosed by the sleeve part. The extension 12 extends from the sleeve part 10 downwards and also backwards to the rear end of the closure head 16a.

Das Verschlußgehäuse 1 ist mit einer in Querrichtung durchgehenden und nach oben offenen Ausnehmung 18 versehen, in welche der erste Ansatz 12 passend eingreift. Diese Ausnehmung 18 weist hinten eine Widerlagerfläche 19 und vorne eine der Widerlagerfläche gegenüberliegende Gegenfläche 20 auf, die schräg nach vorne oben gerichtet ist. Die Widerlagerfläche 19 weist eine Hinterschneidung auf, die die hintere Abstützfläche 21 des Ansatzes 18 teilweise übergreift. Vorne stützt sich der Ansatz 12 mit einer vorderen Abstützfläche 22 an der Gegenfläche 20 ab, wobei der Abstand zwischen beiden Abstützflächen 21, 22 so bemessen ist, daß der Ansatz 12 klemmend in die Ausnehmung 18 paßt.The closure housing 1 is provided with a recess 18 which is continuous in the transverse direction and is open at the top and in which the first projection 12 engages appropriately. This recess 18 has an abutment surface 19 at the rear and a counter surface 20 opposite the abutment surface, which is directed obliquely upwards at the front. The abutment surface 19 has an undercut that partially overlaps the rear support surface 21 of the extension 18. The attachment 12 is supported at the front with a front support surface 22 on the counter surface 20, the distance between the two support surfaces 21, 22 being such that the attachment 12 fits into the recess 18 in a clamping manner.

Zweckmäßig ist die Widerlagerfläche 19, wie es in Fig. 1 dargestellt ist, halbkreisförmig konkav gekrümmt und die hintere Abstützfläche 21 ist passend hierzu halbkreisförmig konvex gekrümmt. Die Widerlagerfläche 19 dient dann beim Verschwenken des Laufes 16 gegenüber dem Verschlußgehäuse 1 als Lagerpfanne.The abutment surface 19, as shown in FIG. 1, is expediently curved in a semicircular shape and the rear support surface 21 is curved in a semicircular manner to match this. The abutment surface 19 then serves as a bearing pan when the barrel 16 is pivoted relative to the breech housing 1.

Die Anordnung könnte auch in umgekehrter Weise, wie es in Fig. 4 dargestellt ist, getroffen sein, wobei die Widerlagerfläche 19' halbkreisförmig konvex gekrümmt ist und die Abstützfläche 21' hierzu passend halbkreisförmig konkav ausgestaltet ist.The arrangement could also be reversed, as shown in Fig. 4, the abutment surface 19 'semicircular mig is convexly curved and the support surface 21 'is designed to be semicircular concave.

Der am vorderen Ende des Hülsenteiles 10 vorgesehene, nach unten vorstehende Ansatz 13 weist eine Riegelausnehmung 23 auf. Mit dieser Riegelausnehmung wirkt ein Riegel 24 zusammen, der im Verschlußgehäuse 1 quer zur Laufachse A verschiebbar ist. Der Riegel 24 wird zweckmäßig durch eine Feder 25 in Sperrstellung gedrückt. Damit er beim Einschwenken des Laufes durch den Ansatz 13 selbsttätig zur Seite gedrückt wird; weist der Ansatz 13 eine Schrägfläche 26 und der Riegel eine Schrägfläche 27 auf.The projection 13 provided at the front end of the sleeve part 10 and projecting downward has a locking recess 23. A bolt 24 interacts with this bolt recess and is displaceable in the breech housing 1 transversely to the running axis A. The bolt 24 is expediently pressed into the locked position by a spring 25. So that it is automatically pushed to the side by pivoting the barrel through the extension 13; the projection 13 has an inclined surface 26 and the latch has an inclined surface 27.

Das Hülsenteil 10 ist mit einer ebenen Bodenfläche 28 versehen, die an einer oberen Anlagefläche 29 des Verschlußgehäuses 1 anliegt. Damit beide Flächen 28, 29 spielfrei aneinandergehalten werden, weist der Riegel 24 eine gegenüber seiner Verschieberichtung B geringfügig geneigte Keilfläche 30 auf, die mit einer entsprechend geneigten Keilfläche 31 der Riegelausnehmung 23 des Ansatzes 13 zusammenwirkt. Die Keilflächen 30, 31 sind in einem Winkel von etwa 3° gegenüber der Verschieberichtung B des Riegels 24 geneigt.The sleeve part 10 is provided with a flat bottom surface 28 which bears against an upper contact surface 29 of the closure housing 1. So that both surfaces 28, 29 are held together without play, the bolt 24 has a wedge surface 30 which is slightly inclined with respect to its direction of displacement B and which cooperates with a correspondingly inclined wedge surface 31 of the bolt recess 23 of the projection 13. The wedge surfaces 30, 31 are inclined at an angle of approximately 3 ° with respect to the direction of displacement B of the bolt 24.

Um den zweiten Ansatz 13 in Querrichtung zur Laufachse gegenüber dem Verschlußgehäuse 1 sicher zu führen, weist das Verschlußgehäuse 1 im Bereich des zweiten Ansatzes 13 eine sich in Richtung der Laufachse A erstreckende Ausnehmung 32 auf, deren sich in Richtung der Laufachse A erstreckenden Seitenflächen seitlich an dem zweiten Absatz 13 anliegen.In order to reliably guide the second attachment 13 in the transverse direction to the barrel axis relative to the breech housing 1, the breech housing 1 in the region of the second attachment 13 has a recess 32 extending in the direction of the barrel axis A, the side surfaces of which extend laterally in the direction of the barrel axis A. the second paragraph 13.

Wie weiterhin aus Fig. 3 ersichtlich ist, weist der Riegel 24 eine sich in Richtung der Laufachse A erstreckende Nut 33 auf, in welche die Führungsleiste 7 des Gehäuseteiles 4 eingreift. Auf diese Weise wird eine ungewollte Verschiebung des Riegels 24 aus seiner in Fig.3 dargestellten Sperrstellung verhindert. Nur wenn das Gehäuseteil 4 bei geöffnetem Verschluß vollständig nach hinten gezogen wird, kommt eine am vorderen Ende der Führungsleisten 7 vorgesehene Ausnehmung 34 im Bereich des Riegels 24 zu liegen. Die Führungsleiste 7 greift dann nicht mehr in die Nut 33 ein und der Riegel 24 kann entgegen der Feder 25 in seine Entriegelungsstellung verschoben werden.As can also be seen from FIG. 3, the bolt 24 has a groove 33 extending in the direction of the running axis A, in which the guide bar 7 of the housing part 4 engages. In this way, an unwanted displacement of the bolt 24 from its locking position shown in Figure 3 is prevented. A recess 34 provided at the front end of the guide strips 7 comes to rest in the region of the latch 24 only when the housing part 4 is pulled completely to the rear with the closure open. The guide bar 7 then no longer engages in the groove 33 and the bolt 24 can be moved against its spring 25 into its unlocked position.

In dieser Stellung gibt der Riegel 24 den vorderen Ansatz 13 frei und der Lauf 16 kann mit seinem vorderen Ende über dem Verschlußgehäuse 1 nach oben geschwenkt werden. Die Widerlagerfläche 19 dient dabei als Lagerpfanne für die hintere Abstützfläche 21 des Ansatzes 12. Wenn der Lauf um etwa 20 bis 30° gegenüber dem Verschlußgehäuse 1 nach oben in die strichpunktierte Lage geschwenkt wurde, kann er in Richtung der Laufachse A nach vorne herausgezogen werden, wobei der Ansatz 12 aus der Ausnehmung 18 heraustritt.In this position, the bolt 24 releases the front shoulder 13 and the barrel 16 can be pivoted upward with its front end over the closure housing 1. The abutment surface 19 serves as a bearing pan for the rear support surface 21 of the extension 12. When the barrel has been pivoted upward by about 20 to 30 ° relative to the breech housing 1 into the dot-dash position, it can be pulled out in the direction of the barrel axis A, wherein the approach 12 emerges from the recess 18.

Da die Führungsnuten 9 im Verschlußgehäuse 1 nach oben offen sind und nach Abnahme des Laufes 16 zusammen mit dem Hülsenteil 10 nicht mehr von letzterem abgedeckt werden, kann nunmehr im Bedarfsfalle das Gehäuseteil 4 zusammen mit seinen Führungsleisten 7, 8 nach oben abgenommen werden.Since the guide grooves 9 in the breech housing 1 are open at the top and after removal of the barrel 16 together with the sleeve part 10 are no longer covered by the latter, the housing part 4 together with its guide strips 7, 8 can now be removed if necessary.

Zur Verbindung des Laufes 16 mit dem Verschlußgehäuse 1 wird der Lauf 16 in strichpunktierter Stellung in Richtung der Laufachse verschoben, bis die Abstützfläche 27 des hinteren Ansatzes 12 an der Widerlagerfläche 19 anliegt. Nunmehr wird der Lauf 16 gegenüber dem Verschlußgehäuse 1 nach unten geschwenkt, wobei der vordere Ansatz 13 in die Aussparung 32 eintritt. Kurz bevor die Bodenfläche 28 mit der oberen Anlagefläche 29 des Verschlußgehäuses 1 in Berührung kommt, legt sich die vordere Abstützfläche 22 an der Schrägfläche 20 an, wodurch der Ansatz 12 mit seiner hinteren Abstützfläche 21 fest gegen die Widerlagerfläche 19 gepreßt wird. Durch die Schrägfläche 26 am vorderen Ansatz 13 und die Schrägfläche 27 am Riegel 24, wird dieser entgegen der Kraft der Feder 25 zur Seite gedrückt und schnappt dann selbsttätig in seine in Fig. 3 dargestellte Sperrsteilung, sobald die Bodenfläche 28 an der Anlagefläche 29 anliegt. Der Riegel 24 läßt eine Funktion des Zylinderverschlusses nicht zu, wenn der Lauf nicht korrekt eingesetzt wurde. Erst wenn der Riegel 24 wieder seine in Fig. 3 dargestellte Sperrstellung erreicht hat, liegt seine Nut 33 wieder im verschiebebereich der Führungsleiste 7 und erst dann läßt sich das Gehäuse 4 des Zylinderverschlusses wieder nach vom verschieben. Der Laufwechsel kann also nur bei geöffnetem Verschluß durchgeführt werden und es ist sichergestellt, daß der Lauf bei Abgabe eines Schusses in exakter Weise fest mit dem Verschlußgehäuse 1 verbunden ist und diese Verbindung auch nicht versehentlich gelöst werden kann.To connect the barrel 16 to the breech housing 1, the barrel 16 is shifted in the dash-dotted position in the direction of the barrel axis until the support surface 27 of the rear extension 12 bears against the abutment surface 19. Now the barrel 16 is pivoted downward relative to the breech housing 1, the front extension 13 entering the recess 32. Shortly before the bottom surface 28 comes into contact with the upper contact surface 29 of the closure housing 1, the front support surface 22 bears against the inclined surface 20, as a result of which the shoulder 12 with its rear support surface 21 is pressed firmly against the abutment surface 19. Due to the inclined surface 26 on the front shoulder 13 and the inclined surface 27 on the bolt 24, the latter is pressed to the side against the force of the spring 25 and then automatically snaps into its locking division shown in FIG. 3 as soon as the bottom surface 28 abuts the contact surface 29. The bolt 24 does not allow the cylinder lock to function if the barrel has not been inserted correctly. Only when the bolt 24 has again reached its locking position shown in FIG. 3, is its groove 33 again in the displacement region of the guide bar 7 and only then can the housing 4 of the cylinder lock be moved again from. The barrel change can therefore only be carried out when the breech is open and it is ensured that the barrel is firmly connected to the breech housing 1 in an exact manner when a shot is fired and this connection cannot be inadvertently released.

Das Hülsenteil 10 weist femer in seinem oberen Bereich ein Aufnahmeprisma 35 für die Halterung eines nicht dargestellten Zielfernrohres auf.The sleeve part 10 also has in its upper region a receiving prism 35 for holding a riflescope, not shown.

Als weiterer Vorteil der erfindungsgemäßen Anordnung sei erwähnt, daß Verbindungsteile nur zwischen dem Verschlußgehäuse 1 und dem Hülsenteil 10 vorgesehen sind. Auf den Lauf werden also durch die Verbindungs- und Befestigungsteile keine Querkräfte ausgeübt. Da letztere nur auf das Hülsenteil und nicht auf irgendwelche ballistischen Elemente einwirken, kann die Treffgenauigkeit in keiner Weise beeinträchtigt werden.As a further advantage of the arrangement according to the invention, it should be mentioned that connecting parts are only provided between the closure housing 1 and the sleeve part 10. No transverse forces are exerted on the barrel by the connecting and fastening parts. Since the latter only act on the sleeve part and not on any ballistic elements, the accuracy can not be affected in any way.

In Fig. 4 ist ein zweites Ausführungsbeispiel dargestellt. Bei diesem Ausführungsbeispiel weist das Hülsenteil 10' an seinem hinteren Ende einen Verschlußkopf 36 mit mehreren radial nach innen ragenden Verriegelungsteilen 37 auf, die mit der Kammer zusammenwirken. Der Lauf 16' ist in diesem Fall von vorne in die Längsbohrung 11' des Hülsenteiles eingesteckt und kann entweder eingelötet sein oder über ein Gewinde 38 mit dem Hülsenteil 10' verbunden sein. Die Verbindungsteile zu dem Verschlußgehäuse 1 sind in gleichartiger Weise ausgebildet, wie bei dem vorhergehend beschriebenen Ausführungsbeispiel, so daß sich eine nochmalige Beschreibung erübrigt.4 shows a second embodiment. In this embodiment, the sleeve part 10 'has at its rear end a closure head 36 with a plurality of radially inwardly projecting locking parts 37 which cooperate with the chamber. In this case, the barrel 16 'is inserted into the longitudinal bore 11' of the sleeve part from the front and can either be soldered in or connected to the sleeve part 10 'via a thread 38. The connecting parts to the closure housing 1 are formed in a similar manner as in the embodiment described above, so that a repeated description is unnecessary.
