Abstract

A firearm enabling and disabling electronic system comprising a base unit (1) and a safety device (4) adapted to be incorporated into a firearm (7). Each of the base unit (1) and the safety device (4) has a transmitter and/or receiver (2, 5) adapted to exchange and process wireless command signals with each other. The safety device (4) has an actuating circuit (6) which is controlled by the transmitter and/or receiver (5) of the safety device (4) and is adapted to actuate a locking mechanism (8), wherein in the locking mechanism is operable to prevent a firearm from firing. The wireless command signal (9) is operable within a predetermined distance between the base unit (1) and the safety device (4) so that when the safety device (4) is located within the predetermined distance from the base unit (1), transmitters and/or receivers (2, 5) exchange the wireless command signal which causes the transmitter and/or receiver (5) of the safety device (4) to prompt the actuating circuit (6) to actuate the locking mechanism (8) thereby causing the locking mechanism (8) to assume a locking mode in which a firearm (7) is prevented from firing.

Claims

wherein the reader device and the tag device are mutually configured so that once the safety device and the tag device are separated by a distance greater than the second predetermined distance range, the reader device prompts the actuating circuit to actuate the locking mechanism thereby causing the locking mechanism to assume a locking mode capable of preventing a firearm equipped with the safety device from firing;

wherein when the safety device is located within the predetermined distance from the base unit, transmitters and/or receivers of the base unit and of the safety device exchange the wireless command signal which causes the transmitter and/or receiver of the safety device to prompt the actuating circuit to actuate the locking mechanism thereby causing the locking mechanism to assume a locking mode capable of preventing a firearm from firing;
