US12449217 - Systems and methods to make safe a firearm

The patent describes a safety system for firearms that includes a rotatable engagement member, which can transition between locked and unlocked positions while remaining attached to the firearm. In the locked position, the engagement member prevents the breechblock from moving forward, ensuring that the firearm cannot be fired until the system is disengaged via a user interface.

Claim 1

1. A safety system for a firearm having a longitudinal axis, the firearm having a breechblock movably coupled to a frame, the safety system comprising: an engagement member movably coupled to the frame, the engagement member being rotatable between an unlock position and a lock position while remaining movably coupled to the frame, the engagement member having a contact face that is in contact with an outer surface of a distal portion of the breechblock in the lock position, a distal end of a primer actuator of the firearm being maintained spaced apart from a primer activation plane of the firearm by a separation distance in response to the engagement member being in the lock position; a lock mechanism operably coupled to the engagement member and positioned to restrict a movement of the engagement member from the lock position while the lock mechanism is in an engaged state; and a user interface operably coupled to the lock mechanism and configured to transition the lock mechanism between the engaged state and a disengaged state. an engagement member movably coupled to the frame, the engagement member being rotatable between an unlock position and a lock position while remaining movably coupled to the frame, the engagement member having a contact face that is in contact with an outer surface of a distal portion of the breechblock in the lock position, a distal end of a primer actuator of the firearm being maintained spaced apart from a primer activation plane of the firearm by a separation distance in response to the engagement member being in the lock position; a lock mechanism operably coupled to the engagement member and positioned to restrict a movement of the engagement member from the lock position while the lock mechanism is in an engaged state; and a user interface operably coupled to the lock mechanism and configured to transition the lock mechanism between the engaged state and a disengaged state.
