A firearm lock mechanism includes a trigger, a hammer, a stirrup connected to the hammer at a stirrup connection point, and a spring operably connected to the stirrup at a spring connection point. Progressive pivoting of the trigger drives corresponding progressive pivoting of the hammer. The stirrup connection point is disposed forward of the hammer pivot point. One of the spring connection point, hammer pivot point, and stirrup connection point is offset relative to and laterally spaced between the others of the points to be a vertex of an intermediate angle cooperatively defined by the points. The angle increases in magnitude as the trigger drives pivoting of the hammer. A toggle line is defined between the trigger pivot point and the hammer pivot point. The trigger contacts the hammer at a contact point that shifts across the toggle line as the trigger drives pivoting of the hammer.

The invention relates to a lock system for a firearm having an arrangement composed of at least two lever arms; in a manner similar to a toggle lever, the lever arms are connected to an axle or shaft in articulating fashion; the resulting toggle lever can be pivoted to both sides of a dead point in which the arrangement is maximally extended; and one of the lever arms is embodied as a hammer for a firing pin.

A firearm with safety mechanism in one embodiment includes a barrel supported by a housing, at least one cartridge-receiving chamber in communication with a bore of the barrel, and a rotatable hammer. The safety mechanism includes a biased safety component, which may be a blocking pin in one embodiment, mounted to and rotatable with the hammer. When the firearm is exposed to an abnormal impact force caused by bumping or dropping the firearm, the safety component changes position and interacts with a blocking feature on the hammer pivot pin to stop or delay the motion of the hammer in a manner which prevents discharging the firearm. The blocking feature may be a notch in one embodiment. Rotating the hammer between rearward cocked and forward firing positions alternatingly aligns or misaligns the blocking pin with the notch, respectively.

A striking mechanism for triggering a firing pin of an externally or self-powered weapon that has a breech. The striking mechanism including a kinematic mechanism having a trigger rocker, a safety device and a release. The trigger rocker acts on the safety device such that the release functionally interacts with a striking hammer. The striking hammer having a telescopic pushrod. A spring mounted around the telescopic pushrod is tensioned when the breech is advanced and a catching edge of the release engages under a catching edge of the striking hammer.

A weapon which has a modular design. The weapon is subdivided into weapon-specific modular assemblies which are designed as carrier units of the components. The modular assemblies include a weapon housing into which a breech system of the weapon and a striking mechanism is provided, a weapon cradle that connects with the weapon housing, and a weapon barrel module. The modular assemblies are connected to each other by rails and guides, by binders and holders, by pins, or by bolts and quick release fasteners.
