<p>The device (1) has electromagnets (5, 8) including cores (6, 9) movably integrated to a body (2) and arranged to have action axes (7, 10) on the body parallel to a linear trajectory (F), respectively. A permanent magnet (11) co-acts magnetically with the core (6) when the body is in its rest/safety position, and the electromagnet (8) is energized to displace the body to an unlocking position. A return spring (13) is associated with the body for displacing the body towards the rest/safety position when the electromagnet (8) is not energized.</p> |
