Description

Die Erfindung betrifft einen Schaft einer Schusswaffe, insbesondere einer Sportwaffe, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a shaft of a firearm, in particular a sporting weapon, according to the preamble of claim 1.

Aus dem Stand der Technik, zum Beispiel der Patentanmeldung GB 2 419 658 A , ist ein Schaft einer Schusswaffe mit einem Backenelement bekannt, dessen Backenauflagefläche in drei Richtungen (X-Achse, Y-Achse und Z-Achse) beweglich ist. Der Nachteil dieses Backenelements und anderer bekannter Backenelemente ist, dass das Auswählen der gewünschten Position der Backenauflagefläche für den Schützen kompliziert ist und nicht ausreichend präzise und insbesondere nicht im Anschlag durchgeführt werden kann. Des Weiteren besteht bei vielen bekannten Backenelementen die Gefahr, dass die Backenauflagefläche in ihrer ausgewählten Position nicht zuverlässig fixiert werden kann, so dass insbesondere durch den Rückstoss die Backenauflagefläche verschoben wird.From the prior art, for example the Patent Application GB 2 419 658 A , a shaft of a firearm with a jaw member is known, the jaw support surface in three directions (X-axis, Y-axis and Z-axis) is movable. The disadvantage of this jaw member and other known jaw members is that selecting the desired position of the jaw support surface for the shooter is complicated and can not be accomplished with sufficient precision and, in particular, not at the ready. Furthermore, in the case of many known jaw elements there is the risk that the jaw support surface can not be reliably fixed in its selected position, so that in particular the jaw support surface is displaced by the recoil.

Die Patentschrift US 7,418.797 B1 offenbart ein mittels Kugelrastvorrichtungen relativ zum Schaft vertikal verstellbares Backenelement.The Patent US Pat. No. 7,418,797 B1 discloses a means of ball detents relative to the shaft vertically adjustable jaw member.

Es besteht somit die Aufgabe einen Schaft einer Schusswaffe, insbesondere einer Sportwaffe, mit einem Backenelement zu schaffen, dass diese Nachteile nicht aufweist. Insbesondere soll die Position der Backenauflagefläche möglichst präzise, auch im Anschlag, einstellbar sein und die ausgewählte Position der Backenauflagefläche zuverlässig beibehalten werden.It is therefore an object to provide a shaft of a firearm, in particular a sporting gun, with a jaw member that does not have these disadvantages. In particular, the position of the jaw support surface as precisely as possible, even at the stop, be adjustable and the selected position of the jaw support surface can be reliably maintained.

Diese Aufgabe wird durch einen Schaft einer Schusswaffe, insbesondere einer Sportwaffe, mit den Merkmalen des Anspruchs 1 gelöst. Ein Schaft einer Schusswaffe gemäß dem Oberbegriff des Anspruchs 1 ist aus der DE 689 07 869 T2 bekannt. Besonders vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angeführt.This object is achieved by a shaft of a firearm, in particular a sporting weapon, with the features of claim 1. A shank of a firearm according to the preamble of claim 1 is known from DE 689 07 869 T2 known. Particularly advantageous developments of the invention are specified in the subclaims.

Erfindungsgemäß umfasst der Schaft einer Schusswaffe, insbesondere einer Sportwaffe, ein Schaftelement und ein Backenelement zur Anlage der Backe des Schützen, wobei das Backenelement eine Backenauflagefläche umfasst, die mittels einer Stellvorrichtung, die eine Kugelrastvorrichtung mit mehreren vorbestimmte Raststufen aufweist, relativ zum Schaftelement bewegbar ist.According to the invention, the shaft of a firearm, in particular a sporting weapon, comprises a shaft element and a jaw element for engaging the jaw of the shooter, wherein the jaw element comprises a jaw support surface, which is movable relative to the shaft element by means of an adjusting device having a ball detent device with a plurality of predetermined detent steps.

Die Verwendung einer Stellvorrichtung mit einer mehrere vorbestimmte Raststufen aufweisenden Kugelrastvorrichtung hat den Vorteil, dass die Position der Backenauflagefläche sehr präzise mittels der Raststufen ausgewählt werden kann. Die formschlüssige Ausbildung der Kugelrastvorrichtung garantiert nach dem Einrasten des oder der konvexen, balligen oder kugeligen Rastelemente in der oder den konkaven Aufnahmen eine zuverlässige Beibehaltung der ausgewählten Position, so dass eine zusätzliche Fixiervorrichtung zur Fixierung der ausgewählten Position nicht unbedingt notwendig ist. Dies erleichtert insbesondere das Verstellen der Backenauflagefläche im Anschlag.The use of an adjusting device having a plurality of predetermined detent stages having ball detent device has the advantage that the position of the jaw bearing surface can be selected very precisely by means of the detent steps. The form-fitting design of the ball detent guarantees after the engagement of the convex or spherical or spherical locking elements in the concave or the receptacles reliable retention of the selected position, so that an additional Fixing device for fixing the selected position is not essential. This facilitates in particular the adjustment of the jaw support surface in the stop.

Ein weiterer Vorteil ist, dass das Einrasten eines Rastelements in einer Aufnahme mit einem Geräusch verbunden ist und somit akustisch und oft auch taktil wahrnehmbar ist, wodurch der Schütze zusätzliche Hinweise erhält, wie weit er die Position der Backenauflagefläche verändert hat. Bevorzugt sind die Rastpositionen gleich weit voneinander entfernt, zum Beispiel im Bereich von 0,1 mm - 2,0 mm, bevorzugt im Bereich von 0,1 mm - 1,0 mm, so dass der Schütze genau weiß, wie weit er die Position der Backenauflagefläche verändert hat, wenn er die taktilen oder akustischen Signale mitzählt.Another advantage is that the engagement of a detent element in a receptacle is associated with a sound and thus acoustically and often tactile perceptible, whereby the shooter receives additional hints how far he has changed the position of the jaw support surface. Preferably, the locking positions are equidistant from each other, for example in the range of 0.1 mm - 2.0 mm, preferably in the range of 0.1 mm - 1.0 mm, so that the shooter knows exactly how far he the position has changed the jaw support surface when it counts the tactile or acoustic signals.

Die Backenauflagefläche ist mittels der die Kugelrastvorrichtung umfassenden Stellvorrichtung vertikal (entlang der Y-Achse) bewegbar.The jaw bearing surface is vertically movable (along the Y-axis) by means of the adjusting device comprising the ball detent device.

Gemäß einem auch eigenständigen, von der bewegbaren Backenauflagefläche unabhängigen erfinderischen Aspekt, der nicht Gegenstand der Ansprüche ist, weist der Schaft der Schusswaffe einen in einer Ebene quer zur Längsachse des Schafts bewegbaren Griff und / oder einen um eine gewinkelt zur Längsachse des Schafts angeordnete Drehachse drehbaren Griff auf. Der relativ zum Schaftelement bewegliche Griff ermöglicht dem Schützen ein noch besseres, stabileres Anlegen und Führen der Waffe.According to an independent, independent from the movable jaw support surface inventive aspect, which is not the subject of the claims, the shaft of the firearm has a movable in a plane transverse to the longitudinal axis of the shaft handle and / or rotatable about an angle to the longitudinal axis of the shaft axis of rotation Grip on. The relative to the shaft member movable handle allows the shooter an even better, more stable application and guiding the weapon.
