Abstract (en)

The invention relates to a trigger mechanism of a firearm, which trigger mechanism (10) comprises a hammer (11), a trigger (12), a disconnector (13), a sear (14), two pivot pins: a front pivot pin (15F) and a central, back pivot pin (15B) , a main spring (16) and two helical springs: a front helical spring (17F) and a back helical spring (17B), and a safety lever (17), which firearm comprises a bolt carrier (20) and a lower receiver (19), and in which the trigger mechanism (10) is located below the bolt carrier (20) and within the lower receiver (19) and the trigger mechanism (10), the bolt carrier (20) and the lower receiver (19) are functionally connected to operate the firearm. The hammer (11) has a back hook (111)with a front part (111F) and a back part (111B), the disconnector (13) comprises a back hook (132), the sear has a retaining hook (142). The front part (111F) of the back hook (111) of the hammer (11) is engageable with a retaining hook (142) of the sear (14). The back part (111B) of the back hook (111) of the hammer (11) is engageable with the back hook (132) of the disconnector (13). The front helical spring (17F) is positioned against the lower receiver (19) and configured to provide first stage force as well as trigger reset and manual cocking functionality in safe mode and the back helical spring (17B) is located between the trigger (12) and the disconnector (13) and is configured to act on the trigger (12) and the disconnector (13).
