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.

Claims

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.

2. ) Device according to claim 1 characterized in that the control mean (6) is of digital type including at least a microprocessor (12) and a memory unit (11).

3. ) Device according to claim 2 characterized in that each transponder (10) is associated in a biunique way to a personal identification code which, in a proximity condition of the transponder (10) to the sensing mean (9), is sensed by this latter and transmitted to the control mean (6) that, in correspondence of the retrieval in its memory (11) of a corresponding enabling code, breaks the electric power supply of the electromagnet mean (2), allowing the opening of the door (4).

4. ) Device according to claim 1 characterized in that the control mean (6) has switching means (8) interposed between each electromagnet mean (2) and supply means (7) of the device (1).

5. ) Device according to claim 4 characterized in that the supply means (7) include rectifier means (20), connected to an alternate voltage AC supply mains, and electric energy battery means (21).

6. ) Device according to claim 1 characterized in that further includes opening sensor means (25) associated to the fixed portion (3) and to the door (4) and connected to the control mean (6) in order to sense an opening condition. of the door (4).

10. ) Device according to-claim 1 characterized in that the control mean (6) has-a connection port (14) for connecting processing means (15) for transrnitting to these latter at least the identification codes of the transponders (10) in a proximity condition to the sensing mean (9) and for receiving the enabling codes to be inserted and/or erased in the memory (1 1).

11. ) Device according to claim 10, characterized in that the connection port (14) is an Ethernet or USB or RS 232 or differential serial or parallel port.

19. The device as recited in claim 1, wherein at least the control mean, the sensing mean and at least the electromagnet mean are fixed inside a first container.

20. The device as recited in claim 1, wherein at least the control mean, the sensing mean, and at least the electromagnet mean are fixed inside a first container.

21. The device as recited in claim 1, wherein each keeper mean is internally fixed to a second container.

22. The device as recited in claim 1, wherein the electromagnet mean is provided with a magnetic core approximately “

E”

shaped and with an electric winding wrapped around the central leg of the magnetic core.

23. The device as recited in claim 22, wherein the electric winding and the magnetic core are enclosed in a synthetic resin layer.

24. The device as recited in in claim 1, further including a plurality of control means each connected at least to respective sensing mean and electromagnetic mean associated to respective doors each provided with a least a keep mean.

25. The device as recited in claim 1, furtherincluding alarm means, wherein said alarm means includes a beeper or a light.

26. The device as recited in claim 6, wherein the control mean operated the alarm mean to generate light signals corresponding to a supply interruption condition of the electromagnetic mean.

27. The device as recited in claim 25, wherein the control mean operated the alarm mean to generate light signals corresponding to a supply interruption condition of the electromagnetic mean.

28. The device as recited in claim 25, wherein the control mean operates alarm means to generate signals corresponding to the opening condition of the door.

7-9. -9. cancel

12. ) Device according to claim I characterized in that the control mean (6) includes a connection (U). for operating opening means (22) connected to the door (4) for opening this latter in correspondence of a supply interruption condition of the electromagnet mean (2) and vice versa.
