WEAPON TRIGGER MECHANISM Russian patent published in 2002 - IPC

FIELD: small arms, applicable in hand fire arms having an automatic fixture with a forward moving barrel. SUBSTANCE: the trigger mechanism, having a firing pin, trigger, lever for transfer of the strike to the hammer pin, is provided with a strut installed on an axle near the lever and linked with the trigger by a spring. A hammer strut is installed between the strut and the trigger. In its one position the strut keeps the lever against the return to the initial state, and in the other position it does not prevent its return to the initial state. The hammer strut either does not prevent installation of the strut for retention of the lever or returns the strut to the initial position and it doesn't act on the lever. Setting of the strut for retention of the lever and release of the firing pin from the search notch are carried out simultaneously. EFFECT: enhanced reliability of fire both by single and automatic shots. 3 dwg
