Description

Die vorliegende Erfindung betrifft ein Gewehr mit einem Gehäuse, einem daran verankerten Lauf und einem unter den Lauf reichenden Vorderschaft, wobei der Lauf mit Hilfe eines eine Querbohrung des Gehäuses durchsetzenden Befestigungsmittels verankerbar ist und der Vorderschaft zumindest einen axialen Fortsatz aufweist, der in eine Aufnahme des Gehäuses lösbar eingreift. Die US 2005/0188584 A1 zeigt ein solches Gewehr.The present invention relates to a rifle having a housing, a barrel anchored thereto, and a fore-end extending under the barrel, the barrel being securable by means of a fastener penetrating a transverse bore of the housing, and the fore-end having at least one axial extension which fits into a receptacle of the Housing releasably engaged. The US 2005/0188584 A1 shows such a rifle.

Gewehre mit wechselbarem Vorderschaft ermöglichen die Verwendung unterschiedlicher Vorderschäfte für verschiedene Einsatzzwecke, beispielsweise eines Vorderschaftes mit ausklappbarem Zweibein für den Scharfschützeneinsatz, eines schlanken Vorderschaftes für den Jagdeinsatz, usw.Rifles with replaceable forend allow the use of different fore shanks for different purposes, such as a forearm with fold-out bipod for the sniper insert, a slender fore-end for hunting use, etc.

Zur lösbaren Befestigung des Vorderschaftes ist es bekannt, den axialen Fortsatz mit federnden Rastnasen auszustatten, die über einen Mechanismus im Inneren des Vorderschaftes zurückgezogen werden können, um den Vorderschaft abzunehmen. Diese Konstruktion ist überaus aufwendig in der Fertigung und störungsanfällig im Betrieb.For releasably securing the forearm, it is known to provide the axial extension with resilient locking lugs, which can be retracted via a mechanism in the interior of the fore-end to remove the forend. This construction is extremely expensive to manufacture and prone to failure during operation.

Die Erfindung setzt sich zum Ziel, eine einfache und sichere Konstruktion zum raschen Auswechseln des Vorderschaftes zu schaffen, welche dabei eine spielfreie Verankerung des Vorderschaftes gewährleistet.The invention has for its object to provide a simple and safe construction for rapid replacement of the fore-end, which ensures a backlash-free anchoring of the forearm.

Dieses Ziel wird mit einem Gewehr der einleitend genannten Art erreicht, das sich erfindungsgemäß dadurch auszeichnet, daß die Querbohrung zur Laufverankerung und die Aufnahme zur Vorderschaftbefestigung einander kreuzen und der Fortsatz eine Rastausnehmung für den Rasteingriff des Befestigungsmittels im verankerten Zustand des Laufes aufweist.This object is achieved with a rifle of the aforementioned type, which according to the invention is characterized in that the transverse bore for the anchorage and the receptacle for Vorderschaftbefestigung intersect and the extension has a recess for the locking engagement of the fastener in the anchored state of the barrel.

Auf diese Weise wird das zur Laufverankerung dienende Befestigungsmittel gleichzeitig für die Befestigung des Vorderschaftes ausgenützt. Damit erübrigen sich komplizierte Rast-und Federmechanismen im Vorderschaft und/oder Gehäuse, denn der Vorderschaft wird bei der Verankerung des Laufes gleichzeitig mitergriffen.In this way, the anchorage serving for fastening means is used simultaneously for the attachment of the forearm. This eliminates complicated locking and spring mechanisms in the forend and / or housing, because of Forearm is simultaneously engaged in anchoring the barrel.

Eine bevorzugte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß das Befestigungsmittel eine Schraube mit einem verbreiterten Kopf ist, welcher in der den Lauf vollständig verankernden Stellung in die Rastausnehmung des Fortsatzes eingreift, hingegen in einer nur teilweise eingeschraubten Stellung die Rastausnehmung freigibt. Dadurch kann in einer Zwischenstellung der Schraube, in welcher der Lauf noch - lose - mit dem Gehäuse verbunden ist, der Vorderschaft abgenommen werden, ohne den Lauf bzw. das Befestigungsmittel selbst vom Gehäuse entfernen zu müssen. Dies stellt eine einfache und wirkungsvolle Art der Verliersicherung dar.A preferred embodiment of the invention is characterized in that the fastening means is a screw with a widened head, which engages in the barrel completely anchoring position in the recess of the extension, however, in a partially screwed position releases the latching recess. As a result, in an intermediate position of the screw, in which the barrel is still loosely connected to the housing, the forearm can be removed without having to remove the barrel or the fastener itself from the housing. This represents a simple and effective way of captive.

Besonders vorteilhaft ist es, wenn gemäß einem weiteren Merkmal der Erfindung der Vorderschaft zwei axiale Fortsätze mit einander zugewandten Rastausnehmungen aufweist, zwischen denen das Befestigungsmittel hindurchtritt. Dadurch kann eine symmetrische Krafteinleitung und noch stärkere Verankerung erreicht werden.It is particularly advantageous if, according to a further feature of the invention, the fore-end has two axial extensions with mutually facing latching recesses, between which the attachment means passes. This allows a symmetrical force application and even stronger anchoring can be achieved.

In jedem Fall ist es besonders günstig, wenn der Vorderschaft einen Innenträger und einen diesen umhüllenden Griffteil aufweist, wobei die Fortsätze als einstückige Verlängerung des Innenträgers ausgebildet sind. Dies ergibt einen besonders stabilen Aufbau des Vorderschaftes.In any case, it is particularly favorable if the fore-end has an inner support and a handle part which surrounds it, wherein the extensions are formed as an integral extension of the inner support. This results in a particularly stable construction of the forearm.

Besonders vorteilhaft ist es dabei, wenn der Innenträger aus Metall oder Kunststoff und der Griffteil aus Kunststoff oder Holz gefertigt ist. Dadurch können je nach Einsatzanforderung besonders günstige, oder alternativ besonders beanspruchungsfeste Verbundkonstruktionen für den Vorderschaft erzielt werden.It is particularly advantageous if the inner support made of metal or plastic and the handle part is made of plastic or wood. As a result, depending on the application requirement, it is possible to achieve particularly favorable or, alternatively, particularly stress-resistant composite structures for the forearm.

Die Erfindung wird nachstehend anhand eines in den beigeschlossenen Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. In den Zeichnungen zeigt

  • Fig. 1 das Gewehr der Erfindung in der Seitenansicht;
  • Fig. 2 den Vorderschaft der Erfindung in einer gesprengten Perspektivansicht;
  • die Fig. 3 und 4 die Verbindung von Lauf und Vorderschaft am Gehäuse in ausschnittsweisen Perspektivansichten einmal vor (Fig. 3) und einmal nach (Fig. 4) dem Verbinden; und
  • Fig. 5 einen Querschnitt entlang der Schnittlinie V-V von Fig. 1.
The invention will be explained in more detail with reference to an embodiment shown in the accompanying drawings. In the drawings shows
  • Fig. 1 the rifle of the invention in side view;
  • Fig. 2 the forend of the invention in a exploded perspective view;
  • the 3 and 4 the connection of barrel and forend to the case in fragmentary perspective views once before ( Fig. 3 ) and once to ( Fig. 4 ) connecting; and
  • Fig. 5 a cross section along the section line VV of Fig. 1 ,

Fig. 1 zeigt ein Gewehr 1 mit einem Gehäuse 2, einem Lauf 3, einem unter den Lauf 3 reichenden Vorderschaft 4 und einem üblichen Hinterschaft 5. Das Gehäuse 2 nimmt einen Verschluß 6, eine Abzugseinrichtung 7 und ein Magazin 8 auf und stellt die Kraftverbindung zwischen allen Komponenten her, wie in der Technik bekannt. Das Gehäuse 2 kann aus einem zentralen Träger und seitlichen Schaftwangen 2' (Fig. 1 und 5) zusammengesetzt sein. Fig. 1 shows a rifle 1 with a housing 2, a barrel 3, a running under the barrel 3 forearm 4 and a conventional buttstock 5. The housing 2 receives a shutter 6, a trigger 7 and a magazine 8 and provides the power connection between all components as known in the art. The housing 2 may consist of a central support and lateral sheep cheeks 2 '(FIG. Fig. 1 and 5 ).

Wie in den Fig. 3 bis 5 gezeigt, ist der Lauf 3 mit Hilfe eines Befestigungsmittels in Form einer Schraube 9 am Gehäuse 2 lösbar verankert. Zu diesem Zweck durchsetzt die Schraube 9 eine vertikale Querbohrung 10 des Gehäuses 2 und greift in ein entsprechendes Gewinde 11 in der Wurzel 12 des Laufes 3 ein.As in the Fig. 3 to 5 shown, the barrel 3 is releasably anchored by means of a fastener in the form of a screw 9 on the housing 2. For this purpose, the screw 9 passes through a vertical transverse bore 10 of the housing 2 and engages in a corresponding thread 11 in the root 12 of the barrel 3 a.

Fig. 2 zeigt den Aufbau des Vorderschaftes 4 im Detail. Der Vorderschaft 4 weist einen Innenträger 12 aus Kunststoff oder Metall auf, z.B. Aluminium. Der Innenträger 12 ist in eine axiale Nut 13 eines umhüllenden Griffteiles 14, beispielsweise aus Kunststoff oder Holz, eingeschoben und dort mit Hilfe einer Wurmschraube 15 axial festgelegt. Fig. 2 shows the structure of the forearm 4 in detail. The forearm 4 has an inner support 12 made of plastic or metal, for example aluminum. The inner support 12 is inserted into an axial groove 13 of an enveloping handle part 14, for example made of plastic or wood, and axially fixed there by means of a worm screw 15.

Der Innenträger 12 ist auf seiner dem Gehäuse 2 zugewandten Seite in Form zweier axial auskragender Fortsätze 16 verlängert. Die Fortsätze 16 greifen in Axialrichtung in zwei schlitzförmige Aufnahmen 17 des Gehäuses 2 ein (Fig. 3).The inner support 12 is extended on its side facing the housing 2 in the form of two axially projecting extensions 16. The extensions 16 engage in the axial direction in two slot-shaped receptacles 17 of the housing 2 a ( Fig. 3 ).

Im Gehäuse 2 kreuzen sich die Aufnahmen 17 und die Querbohrung 10. Die Fortsätze 16 besitzen einander zugewandte Rastausnehmungen 18 und die Schraube 9 weist einen verbreiterten Kopf 19 auf, welcher im verankerten Zustand des Laufes 3 (Fig. 5) in die Rastausnehmungen 18 eingreift und damit die Fortsätze 16 im Gehäuse 2 arretiert.In the housing 2, the receptacles 17 and the transverse bore 10 intersect. The extensions 16 have mutually facing latching recesses 18 and the screw 9 has a widened head 19, which in the anchored state of the barrel 3 (FIG. FIG. 5 ) engages in the recesses 18 and thus locks the extensions 16 in the housing 2.

Wie Fig. 5 zeigt, ist die Länge des Eingriffes des Kopfes 19 in die Rastausnehmungen 18 kürzer als der Eingriff der Schraube 9 in das Gewinde 11, sodaß bei einem teilweisen Herausdrehen der Schraube 9 zuerst die Rastausnehmungen 18 außer Eingriff kommen und ein Abziehen des Vorderschaftes 4 ermöglichen, bevor noch der Lauf 3 vom Gehäuse 2 vollständig gelöst werden kann.As Fig. 5 shows, the length of engagement of the head 19 in the recesses 18 is shorter than the engagement of the screw 9 in the thread 11, so that at a partial unscrewing the screw 9 first the recesses 18 are disengaged and allow removal of the forearm 4 before still the barrel 3 can be completely detached from the housing 2.

Die Erfindung ist nicht auf die dargestellten Ausführungsformen beschränkt, sondern umfaßt alle Varianten und Modifikationen, die in den Rahmen der angeschlossenen Ansprüche fallen.The invention is not limited to the illustrated embodiments, but includes all variants and modifications that fall within the scope of the appended claims.
