An inertia-resistant preventer mechanism is provided for use in a firearm safety enhancement system to reliably and selectably prevent or to unblock a firing mechanism of a firearm. The inertia-resistant preventer mechanism includes a first solenoid having a moveable blocking rod with a first actuation response speed. The blocking rod is normally interposed in the firearm to prevent activation of the firing mechanism and is selectably activated to unblock the firing mechanism. A second solenoid is also included, having a second blocking rod with a second actuation response speed equal to or faster than the response speed of the first solenoid. The second blocking rod of the second solenoid is normally interposed at an angle to the first solenoid to block the first blocking rod of the first solenoid against accidental unblocking caused by inertia and relative movement of the firearm. The second solenoid is selectably activated to unblock the first rod of the first solenoid substantially simultaneously with, or prior to, actuation of the first blocking rod to unblock the firing mechanism of the firearm.

Inertia-resistant preventer mechanism for firearm safety enhancement system

A firearm safety enhancement system is provided for enabling use of a firearm only by an authorized individual. At least one electrically activated preventer is provided having a first position for preventing use of firearm and having a second position for enabling use of the firearm. An electrical activation circuit is operatively connected to the preventer to move the preventer between the first and second positions. A portable power supply is carried in said firearm and is coupled to the activation circuit for providing power. A power signal transmitter is operatively connected to the power supply for transmitting an electromagnetic power signal at a regular frequency. A passive identification tag is mounted to a personal adornment to be carried or worn by an individual and is preprogrammed with an authorized identification code preselected from a large number of available identification codes. The passive identification tag is responsive to the power signal to impose a coded return signal on the power signal. The return coded signal is representative of the preprogrammed authorized identification code so that the power signal acts as a carrier of the imposed coded return signal. A reader circuit is connected to the power signal transmitter and to the electrical activation circuit. The reader circuit is responsive only to an authorized identification code to activate the electrical activation circuit to provide power from the portable power supply to move the at least one preventer between the first preventing position and the second unblocked position for enabling use of the firearm.
