US12405077 - Remotely activated firearm accessory

The invention relates to an electronic device that is used to block the accessibility of a firearms Trigger. Wherein an electronic device is mounted on a rail or rail accessory and is locked in place using a lock and frame allowing the device to fit an array of firearms. The lock and frame are in place to stop easy removal unless the possessor has the key to remove them. The device its self uses a battery to operate and picks up a transmission broadcasted from a Bluetooth within its programmed range by the use of a Bluetooth proximity detector. Once the transmission has been picked up it activates its locking mechanism in the form of a solenoid causing its pin to shift and allows a slide placed in front of the trigger acting as a second trigger to move back and forth allowing the movement of the firearms trigger. The slide is moved back into its original position by the use of a spring. When the Bluetooth is out of the device's proximity detectors programmed range, the solenoid returns to its locked state stopping access to the trigger. Making the trigger locking device a beneficial reusable safety device.
