Abstract
The firing mechanism for a rifle comprises a trigger (2) fixed to a trigger blade (4) and a two-armed firing lever (5) pivoting in the breech housing, the first lever arm (5a) being directly or indirectly connected to a firing sear (7) which holds a retainer (10) on the end (11a) of the firing pin in the cocked position, whereby the firing spring exerts a turning moment on the firing lever (5) in the cocked position, through the firing pin, the retainer (10) and the firing sear (7). A link (13) is hinged at one end to the trigger blade (4) and at the other end to the second lever arm (5b) by means of two hinge axes (14, 15) running parallel to the trigger axis (3). The first hinge axis (14) at the trigger blade is so arranged relative to the second hinge axis (15) at the second lever arm (5b) that, in the cocked position (FIGS. 2, 4, 6) of the firing mechanism, the link (13) is in compression, and the second hinge axis (15) lies a small distance (a) from a straight connecting line (V) running through the first hinge axis (14) and the trigger axis (3). Accordingly, on cocking the second hinge axis (15) is moved slightly over-center beyond a dead-point position of the link (13) determined by the connecting line (V). A stop (16) is provided on the trigger blade (4) which stop limits the over-center movement of the link (13) and on which the link (13) bears in the cocked position under the action of the turning moment (M).
