Abstract (en)

A collimator fitting for the front end of a gun barrel uses a dovetail fitting to slide the collimator (3) axially onto support blocks (11,12) on the barrel with sloping grips edges under the collimator and on the blocks. The dovetailed gripping surfaces have an angle of 2 to 5 degrees between them to prevent jamming. A transverse wedge (14) is pulled between the collimator and the barrel by a screw (20) to secure the fitting. The gap between the wedge and the clamping faces is between 3 and 8 degrees. This prevents the collimator jamming to the fitting when the barrel is hot.

Abstract (de)

Die Erfindung betrifft ein Waffenrohr (1) mit einer im Bereich der Rohrmündung (2) angeordneten Kollimatorhalterung (3) zur Befestigung eines Kollimators einer Feldjustieranlage. Um zu erreichen, daß die Kollimatorhalterung leicht, anwenderfreundlich und spielfrei montierbar ist, schlägt die Erfindung vor, als Kollimatorhalterung (3) einen Schlitten mit einer Schwalbenschwanzführung (7,8) zu verwenden, wobei die beiden seitlichen Führungsflächen der Schwalbenschwanzführung (7,8) einen keilförmigen Verlauf aufweisen. Der Schlitten (3) ist auf eine an der Rohrmündung (2) befindliche Schwalbenschwanzaufnahme (11,12) aufgeschoben, deren seitliche Führungsflächen ebenfalls keilförmig ausgebildet sind. Durch die in axialer Richtung geneigten seitlichen Führungsflächen der Schwalbenschwanzführung (7,8) in Verbindung mit der Neigung der Führungsflächen aufgrund des Schwalbenschwanzprofils, kommt es zu einem Verspannen des Schlittens (3) mit der waffenrohrseitigen Aufnahme (11,12). <IMAGE>
