Novelty: Lock securing method and mechanism are disclosed. Constitution: The electromagnet (1) (fig.1), the electromagnet's moving stem (6) blocking -when in position A- the lock's moving parts which will be released when said stem (6) is energized in the position B; the reed switch (2) inciting, via a magnet, the closure of the magnet's contacts and the actuation of the lock-unlocking electromagnet (1); the 12-volt power feeder (3), and the relay (4) connecting, in case of power interruption, the circuit to the battery (5); two cell phone activation circuits can be utilised at the place of the foregoingreed switch: the one circuit is apt to be promptly energized for causing the instant unlocking the lock while the other circuit will be actuated within little time-delay margins. |
