Abstract

EL INVENTO SE REFIERE A UN DETECTOR DE CONTROL MAGNETICO DEL DESPLAZAMIENTO DE UN ORGANO MOVIL EN RELACION A UN ORGANO FIJO PARA SISTEMAS DE APERTURA. EL DETECTOR CONSTA DE UN CONTACTO ELECTRICO MONTADO EN UN CIRCUITO DE ALARMA QUE VA EN UNO DE DICHOS ORGANOS, DE FORMA QUE QUEDA SITUADO EN EL CAMPO MAGNETICO DE UN IMAN PRINCIPAL (1) QUE VA EN EL OTRO ORGANO, CUANDO EL SISTEMA ESTA CERRADO, Y UN CONTACTO DE SEGURIDAD (6) SENSIBLE A CAMPOS MAGNETICOS NO PRODUCIDOS POR EL IMAN PRINCIPAL Y SITUADOS SOBRE EL ORGANO PORTADOR DEL CONTACTO DE ALARMA. SE CARACTERIZA PORQUE EL ORGANO PORTANTE (4) DEL CONTACTO PRINCIPAL DE ALARMA (5) TIENE ADEMAS ELEMENTOS DE GUIA (8,9) DE CAMPOS MAGNETICOS EXTERNOS HACIA DICHO CONTACTO DE SEGURIDAD (6) Y UN SEGUNDO IMAN (7) SITUADO DE MANERA QUE FORMA PANTALLA ENTRE EL IMAN PRINCIPAL (1) Y EL CONTACTO DE SEGURIDAD (6) PARA REDUCIR LA INFLUENCIA DE ESTE IMAN (1) SOBRE EL CONTACTO DE SEGURIDAD (6). EL INVENTO PUEDE UTILIZARSE EN CAJAS FUERTES.THE INVENTION REFERS TO A DETECTOR FOR MAGNETIC CONTROL OF THE DISPLACEMENT OF A MOBILE ORGAN IN RELATION TO A FIXED ORGAN FOR OPENING SYSTEMS. THE DETECTOR CONSISTS OF AN ELECTRICAL CONTACT MOUNTED IN AN ALARM CIRCUIT THAT GOES IN ONE OF THESE ORGANS, SO THAT IT IS LOCATED IN THE MAGNETIC FIELD OF A MAIN MAGNET (1) THAT GOES IN THE OTHER ORGAN, WHEN THE SYSTEM IS CLOSED, AND A SAFETY CONTACT (6) SENSITIVE TO MAGNETIC FIELDS NOT PRODUCED BY THE MAIN MAGNET AND LOCATED ON THE BODY BEARING THE ALARM CONTACT. IT IS CHARACTERIZED BECAUSE THE BEARING ORGAN (4) OF THE MAIN ALARM CONTACT (5) ALSO HAS GUIDE ELEMENTS (8,9) OF EXTERNAL MAGNETIC FIELDS TOWARD SUCH A SAFETY CONTACT (6) AND SITUATED IN A WAY THAT DISPLAY FORM BETWEEN THE MAIN MAGNET (1) AND THE SAFETY CONTACT (6) TO REDUCE THE INFLUENCE OF THIS MAGNET (1) ON THE SAFETY CONTACT (6). THE INVENTION CAN BE USED IN SAFE BOXES.
