US12379176 - 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 or sends a broadcasted transmission within a programmed range by the use of a printed circuit board (PCB) capable of receiving or sending a broadcasted transmission. Once the transmission has been picked up or sent and received it activates the electronic devices locking mechanism in the form of a electromechanical mechanism causing it 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 driven mechanism. When the worn device or the electronic device is out of the programmed range, the electromechanical mechanism returns to its locked state stopping access to the trigger. Making the trigger locking device a beneficial reusable safety device.

The patent describes a remotely activated firearm accessory designed to electronically block access to a firearm’s trigger, utilizing a locking mechanism that can only be disengaged with a specific key. This device incorporates a printed circuit board for communication and control, allowing it to secure the trigger when out of range, enhancing firearm safety.

Claim 1

A firearm trigger locking accessory comprising: a slide which protrudes from a housing extending out to cover the trigger from the front, the right side, the left side, and the back side, while still allowing access within the trigger guard, said slide being permanent or interchangeable; a printed circuit board (PCB) capable of sending or receiving broadcasted radio transmissions and activating an electromechanical mechanism, a power source, a switch configured to control or partially control said printed circuit board (PCB), an electromechanical mechanism involved in locking and unlocking said slide; a spring driven mechanism to assist moving said slide back into its lockable position; a means of attaching the housing onto a firearm by the use of a rail or rail accessory; and a frame, extending over the firearm, configured to secure the accessory in place and lock with a key.
