Abstract

LA INVENCION SE REFIERE A UN INTERRUPTOR DE SEGURIDAD (10), EN CUYA CAJA DE INTERRUPTOR (11) SE APOYA UN PERNO DE BLOQUEO CARGADO POR UN MUELLE (14), DESPLAZABLE AXIALMENTE, PARA DESPLAZAR EL INTERRUPTOR A UNA POSICION QUE BLOQUEA Y LIBERA UN ELEMENTO DE CONEXION, DONDE EL MOVIMIENTO A LA POSICION DE DESBLOQUEO VIENE DADO POR UN IMAN ELEVADOR. EL OBJETIVO ES CONSEGUIR UNA CONSTRUCCION SENCILLA QUE REDUZCA SENSIBLEMENTE EL CONSUMO DE ENERGIA NECESARIO PARA SUJETAR EL PERNO SE BLOQUEO (14) EN LA POSICION DE DESBLOQUEO. SEGUN LA INVENCION, EL INTERRUPTOR DE SEGURIDAD (10) LLEVA TAMBIEN UN IMAN DE FIJACION MAGNETICA (21) QUE SUJETA EL PERNO DE BLOQUEO (14) EN LA POSICION DE DESBLOQUEO DE FORMA QUE EL IMAN ELEVADOR ESTA SIN CORRIENTE EN ESTA POSICION. EL INDUCIDO (18) DEL IMAN ELEVADOR (19) Y EL INDUCIDO (20) DEL IMAN DE FIJACION (21) ESTAN ARTICULADOS EN UN EXTREMO DE UNA PALANCA REVERSIBLE (16) PERPENDICULAR AL PERNO DE BLOQUEO (14). EL EXTREMO OPUESTO DE LA PALANCA (16) SE ARTICULA EN UN EJEFIJO (17) Y ESTA CONECTADO CON EL PERNO DE BLOQUEO (14) EN UNION DE ARRASTRE. EL PERNO DE BLOQUEO (14) ESTA FIJADO EN UNA TRAVIESA (22). EN LA TRAVIESA (22) SE APOYA EL EXTREMO DE UN MUELLE DE PRESION (23) QUE MANTIENE EL PERNO DE BLOQUEO (14) EN LA POSICION DE BLOQUEO. EL OTRO LADO DEL MUELLE (23) ESTA EN CONTACTO CON LA PALANCA REVERSIBLE (16). EL INTERRUPTOR DE SEGURIDAD SE UTILIZA EN AQUELLOS CASOS EN LOS QUE CONVIENE ASEGURAR QUE CON EL ACCIONADOR EXTRAIDO SE ACTIVE FORZOSAMENTE LA POSICION DE DESCONEXION.
