Abstract: The invention relates to a firing mechanism for a firearm, comprising a housing in which a spring-loaded firing pin is guided in a guide, which firing pin can be held in a cocked position by means of a firing pin lug which latches on a latching tab of a latching piece and lies radially on one side of the firing pin, with the firing pin being guided in the guide via at least one roller, and wherein the roller lies on that side of the firing pin that is located radially opposite to the firing pin lug.

Abstract: A pistol comprises a housing and a slide which slides on this housing and contains the barrel and the breech, in which case the breech has a mainspring and a firing bolt, and a trigger acts via a trigger rod on the trigger device.

Abstract: The pistol comprises a housing composed of plastic and a barrel slide (which contains a barrel and a breech and is guided in the longitudinal direction with respect to the housing) as well as a trigger mechanism. In order to allow plastics technology to be used to a large extent, with high precision and easy assembly, a single multifunction part, which is composed of metal, is inserted removably into the housing, on which multifunction part the guides for the barrel slide are formed and in which the elements of the trigger mechanism are mounted and guided. The multifunction part has a hole which holds the disassembly lever shaft and thus produces the connection between the housing and the multifunction part. Furthermore, a recess for a projection of the multifunction part is provided in the rear wall of the housing.

Abstract: A pistol comprises a butt containing a trigger mechanism and a barrel slide which can be displaced in the longitudinal direction, the trigger being guided in the upper part of the butt. In order to permit rapid, simple and reliable locking and unlocking, a locking pin is guided so that it can be displaced and rotated in a lateral transverse hole in the butt. The locking pin protrudes into the path of the trigger in the locked condition. A compression spring acts on the locking pin in the unlocked position and the locking pin has a head which interacts in bayonet fashion with an enlarged portion of the hole so that two different angular positions of the locking pin correspond to the locked and unlocked positions are selected.

Abstract: A firearm, particularly a piston, is provided with a trigger mechanism, which comprises a spring-loaded trigger rod, a trigger for moving the trigger rod, and locking means for preventing a movement of the trigger rod other than by an operation of the trigger. The trigger rod is slidably mounted and guided in the receiver of the firearm for a movement along a straight line. The trigger is directly mounted on the trigger rod for a limited pivotal movement. A spring is provided, which biases the trigger for a forward pivotal movement and exerts a forward tensile force on the trigger rod and when the trigger is in its initial position retains a nose of the trigger in a notch of the receiver.

Abstract: A hand-held automatic firearm comprises a breechblock, which is longitudinally slidably guided and at its forward end has a standing face for engaging a cartridge, a hammer, which is adapted to be cocked by the breechblock as it recoils, a sustained-fire lever, which is controlled by the breechblock and catches the hammer as the breechblock advances, and an ejector, which is movable relative to the breechblock and ejects the cartridge case as the breechblock recoils. In order to provide a compact and inexpensive design, the sustained-fire lever comprises a follower arm, which protrudes toward the barrel and extends into a track groove, which is formed in the breechblock and opens into the standing face, and the follower arm has a free end, which acts as an ejector.

Abstract: A hand-held automatic firearm comprises a trigger mechanism, which includes a hammer, arranged to be cocked as the breechblock recoils, a sustained-fire lever, controlled by the breechblock and locks the hammer as the breechblock advances, a trigger slider, movable by the trigger against spring force from an initial position to a single-shot position and further to a sustained-fire position, and a pair of mutually cooperating levers, which respectively constitute a release member and a disconnector member and are adapted each to enter the path of movement of a hammer extension and to assume a position that depends on the position of the trigger slider. The release lever and the disconnector lever are pivoted on a common upright pivot and have respective confronting camming side edges, which define between them a cam slot. A camming member is movable by the trigger slider and extends into said cam slot.

Abstract: In a mechanical sighting device for rifles, the front sight (6) is adjustable vis-a-vis the rifle barrel (1) as to height and sidewardly. In order to enable a height- and a sideward-adjustment independently of each other, and to guarantee at the same time a sturdy construction to be operable in a simple manner, the carrier (3) is supported slewably about the rifle barrel (1), and there is provided a finger (2) affixed on the rifle barrel (1). In the carrier (3) there is supported a setting screw (11) which crosses at right angle the rifle barrel (1), or the swivel axis of the carrier (3), respectively, and is supported on the finger (2). The foresight (6) is screwed into a bore (5) radial to the swivel axis of the carrier (3).
