US12385708 - Safety for firearm electromagnetic firing system

An electronic trigger system with safety mechanism for firearms includes a trigger unit comprising an electromagnetic actuator operably coupled to the firing mechanism and a programmable trigger mechanism microcontroller. The actuator is changeable between a non-powered unactuated position and powered actuated firing position via pulling both an outer trigger and inner safety trigger of the trigger unit. The actuator is operably interfaced with a movable firing component of the firing mechanism operable to discharge the firearm. In a blocking position of the safety trigger, the safety trigger is configured to block outer trigger movement which prevents energizing and actuating the electromagnetic actuator thereby preventing the firearm from discharging. Conversely in an unblocking position, the safety trigger allows outer trigger movement sufficient to discharge the firearm by either energizing the actuator when a pre-selected trigger pull force threshold is applied or applying sufficient trigger force to manually trip the actuator.

firearmelectronictriggersafety

The patent describes an electronic trigger system for firearms that incorporates a safety mechanism, allowing the firearm to be discharged only when both an outer trigger and an inner safety trigger are engaged appropriately. The system features an electromagnetic actuator that can be controlled to either block or enable the discharge of the firearm based on the position of the safety trigger.

Claim 1

A firearm with electronic firing system comprising: a chassis or frame; a trigger mechanism coupled to the chassis or frame, the trigger mechanism comprising an electromagnetic actuator including a moving member configured and operable to discharge the firearm when actuated; the trigger mechanism further comprising: a movable outer trigger; an inner safety trigger pivotably movable with respect to the outer trigger; and a coil operably coupled to an electric power source and the electromagnetic actuator, the coil when energized operable to generate a magnetic field in the electromagnetic actuator which actuates the moving member; wherein the inner safety trigger is movable between a first position which prevents actuation of the electromagnetic actuator, and a second position which allows actuation of the electromagnetic actuator to discharge the firearm when the outer trigger is pulled; wherein the electromagnetic actuator further comprises a permanent magnet which generates a static magnetic field creating a primary resistance force opposing movement of the outer trigger when pulled by a user. a chassis or frame; a trigger mechanism coupled to the chassis or frame, the trigger mechanism comprising an electromagnetic actuator including a moving member configured and operable to discharge the firearm when actuated; the trigger mechanism further comprising: a movable outer trigger; an inner safety trigger pivotably movable with respect to the outer trigger; and a coil operably coupled to an electric power source and the electromagnetic actuator, the coil when energized operable to generate a magnetic field in the electromagnetic actuator which actuates the moving member; a movable outer trigger; an inner safety trigger pivotably movable with respect to the outer trigger; and a coil operably coupled to an electric power source and the electromagnetic actuator, the coil when energized operable to generate a magnetic field in the electromagnetic actuator which actuates the moving member; wherein the inner safety trigger is movable between a first position which prevents actuation of the electromagnetic actuator, and a second position which allows actuation of the electromagnetic actuator to discharge the firearm when the outer trigger is pulled; wherein the electromagnetic actuator further comprises a permanent magnet which generates a static magnetic field creating a primary resistance force opposing movement of the outer trigger when pulled by a user.
