FIRING AND LAUNCHING MODULE OF SMALL ARMS Russian patent published in 2020 - IPC F41C7/00 

FIELD: weapons.

SUBSTANCE: firing and launching module of small arms of modular design comprises body, trigger, split plate spring, hammer with firing hook, balance arm. Floating leaf spring is divided into at least two lobes, one of which is narrower and shorter is spring-loaded element for trigger, and other wider interacts with its end, as sear, with hammer firing hook. When the trigger is pressed, the rocker arm of the rocker moves upward and interacts with the narrow short lobe of the plate spring, and the front part of the balance arm moves down interacting with the second spring lug, which is closer to its end, it shifts it from the trigger hammer catch, allowing the trigger provided with the lateral ledge-disconnector to move towards the striker. At the end of the movement, the side ledge-uncoupler interacting with the lateral part of the front arm of the rocker, shifts it aside from the plane of the expanded part of the spring, thus allowing the end part of the lug to return to the initial position and again fixing the hammer combat hook by putting the trigger mechanism on military cocking.

EFFECT: technical result is improved design of impact mechanisms, creation of compact module impact and trigger mechanism.
