Abstract (en)
[origin: US4760663A] A firearm comprises a housing, a barrel extending in a first direction, a chamber structure, a trigger and firing means, wherein the chamber structure is constituted by a chamber member, which is separated from the barrel and is movable in the housing in a second direction, which is transverse to the barrel axis, and an actuating mechanism is provided for reciprocating said chamber member in said second direction between a firing position and a loading position. The actuating mechanism comprises a slider, which is movable in said first direction from an initial position to a stand-by position, said slider is adapted to be releasably locked in either of its said positions and comprises a cam opening, which has a can face that extends over the width that is traversed by the chamber member, and cooperates with an actuating pin, which is coupled to the chamber member for a movement in said second direction and extends in a third direction, which is transverse to said first and second directions. A spring drive is provided for moving the chamber member from its loading position to its firing position, the cam opening formed in the slider has substantially the configuration of a right-angled triangle in which the hypotenuse constitutes a cam face and in which the legs respectively extend in the direction of movement of the slider and in the direction of movement of the chamber member and define an apex which constitutes a coupling stop for engaging the actuating pin, the actuating pin is a sliding fit in a coupling slot that is formed in the chamber member and is parallel to the barrel, the actuating pin extends through the cam opening in the slider and at opposite ends extends into guide slots formed in the housing.
