Electromechanical safety for weapons, and weapon provided with the same

Electromechanical safety apparatus for weapons (1), provided with a mechanical safety device, comprising a base electronic unit, actuating an electromechanical transducer (2) acting on the safety mechanical device, and at least a transmitter—responder, or transponder (5), the base unit providing a central control and processing unit, connected with a transceiver unit (4), continuously transmitting an enquiry signal, able to talk with said at least one transponder (5), when the latter is within the transmission range of the transceiver unit (4), said at least one transponder (5) having no power supply and receiving the power necessary to its operation from the signal transmitted by the transceiver unit (4), said at least one transponder (5) transmitting, when supplied, an identification code, the base unit actuating the electromechanical transducer (2) in such a way to release the safety mechanical device when receives an identification code corresponding to a code stored into the base unit and actuating the electromechanical transducer (2) in such a way to insert the safety mechanical device as soon as the base unit no more receives said identification code, wherein the base electronic unit is provided with one or more rechargeable supply batteries, and wherein the charge level of the batteries is checked by the control and processing central unit in such a way that, in case the safety mechanical device is released and the voltage of the batteries falls to a threshold level still sufficient for the operation of the base unit and of the electromechanical transducer (2), said central unit activates a self-turning off circuit actuating the electromechanical transducer (2), so as to reinstate the safety mechanical device and then turns the base electronic unit off.
