Firing blocker mechanism for firearm

摘要

A striker-fired firearm in one embodiment includes a firing mechanism having a spring-biased blocker movable into and out of the linear path traveled by the striker to reach a chambered cartridge. A sear operates to hold the striker in a cocked position. A blocker lifter actuated by a trigger mechanism via a trigger pull raises the blocker and actuates the sear to release the striker for discharging the firearm. Upon release of the trigger, the blocker automatically returns to a blocking position obstructing the linear travel path of the striker to disable the firing mechanism.

主权项

1. An auto-loading firearm with striker firing mechanism comprising:
a longitudinal axis; a frame; a barrel defining a chamber for holding a cartridge; an elongated striker movable along the longitudinal axis in a linear path to strike a chambered cartridge; a sear pivotably disposed in the frame and configured to hold the striker in a rearward cocked position; a blocker movable from a non-blocking position to a blocking position obstructing the linear path of the striker; a blocker lifter pivotably disposed in the frame and operably linked to a trigger mechanism having a trigger; and a biasing member urging the blocker into the blocking position; wherein pulling the trigger rotates the blocker lifter which engages and moves the blocker from the blocking position to the non-blocking position allowing the firearm to be discharged; wherein rotation of the blocker lifter engages and rotates the sear to release the striker from the cocked position for discharging the firearm.
