ELECTRONIC LOCK WITH RADIO FREQUENCY IDENTIFICATION FOR METAL DOORS

摘要

Electronic lock with radiofrequency identification, for metal doors; of the type that consist of electronic means with a chip (C2) and an antenna (a2) that control means (3) that allow/do not allow the movement of a knob/button (4) of the lock for its opening/closing; and of the type that use a card or similar (for example, a wrist band or a key ring) (1) for opening/closing that consists of electronic means with a chip (C1) and an antenna (a1). It places concentrically to the knob/button (4) a plate-antenna (8) that is structured in a first sheet (81) supporting a passive amplifier antenna and a second sheet (82) supporting a ferrite that acts as an anti-interferences filter. It may have a non-metallic shield (9) that set into the metal walls (7) where the lock is located, contains inside it the aforementioned plate-antenna (8).

1. An electronic lock with radio frequency identification, for metal doors; of the type that consist of electronic means with a chip (C2) and an antenna (a2) that control the means that allow/do not allow the movement or the blocking of a knob/button of the lock for its opening/closing; and of the type that uses a card or similar (for example, a wrist band or a key ring) for opening/closing that consists of electronic means with a chip (C1) and an antenna (a1); wherein it places concentrically to the knob/button a plate-antenna that is structured in a first sheet supporting a passive amplifier antenna and a second sheet supporting a ferrite that acts as an anti-interferences filter.
