Magnetic lock device operated by means of transponder
First Claim
1. ) Magnetic lock device operated by means of transponder provided with at least a electromagnet mean (2) connected to a fixed portion (3) of a door (4) and with at least a:
- keeper mean. (5) fixed to the door (4) and, in a closing condition of this latter, facing the electromagnet mean (2) which, in an electric supply condition, magnetically attracts and blocks said keeper mean (5), said device (1) being characterized in that includes;
a control mean (6) for switching the electric supply of the electromagnet mean (2);
a sensing meani (9) in data connection with the control mcan (6) and fit. to sense the proixmity of a plurality of mobile transponders (10) each one associate to a respective operator;
the control mean (6) being fit for breaklng the electric power supply to the electromagnet mean (2) when the sensing mean (9) senses the proximity of at least a transponder (10) and vice versa.

Abstract
A magnetic lock device operated by means of transponder is provided with at least an electromagnet mean (2) connected to a fixed portion (3) of a door (4) and with at least a keeper mean (5) fixed to the door (4) and, in a closing condition of this latter, facing the electromagnet mean (2). The device (1) includes: a control mean (6) for switching the electric supply of the electromagnet mean (2); a sensing mean (9) in data connection with the control mean (6) and fit to sense the proximity of a plurality of mobile transponders (10) each one associate to a respective operator. The control mean (6) is fit to interrupt the electric supply to the electromagnet mean (2) when the sensing means (9) senses the proximity of at least a transponder (10) and vice versa.
