Abstract

SE DESCRIBE UNA POLEA MEJORADA ASCENDENTE Y DESCENDENTE (1) PARA APARATOS DE ALUMBRADO, CARACTERIZADA EN TANTO QUE COMPRENDE UN GRUPO DE FRENADO CONSTITUIDO POR UNA RUEDA DE FRENADO DENTADA (9) SUJETA FIRMEMENTE ENTRE MEDIOS DE CONEXION ROSCADOS (11) ACOPLADOS AL EJE GIRATORIO CENTRAL (5) DEL TAMBOR PARA ENROLLAR EL CABLE DE SUSPENSION (27) DE LA POLEA ASCENDENTE Y DESCENDENTE Y UNA TUERCA DE BLOQUEO DE ANILLO ROSCADO (10) ATORNILLADA EN DICHO MEDIO DE CONEXION (11), QUE, JUNTO CON SU TUERCA DE BLOQUEO (10), ESTA ROSCADO EN UNA DIRECCION OPUESTA A LA DE ROTACION DEL TAMBOR (4) DURANTE EL DESCENSO DEL CABLE (27), QUE MANTIENE DICHA RUEDA DE FRENADO DENTADA (9) SIEMPRE APRETADA Y BAJO FRICCION, AUTORREGULANDOSE, DE ESTE MODO, DURANTE SU USO, COMPENSANDO CUALQUIER HUELGO QUE SE FORME CON EL PASO DEL TIEMPO. LA POLEA ASCENDENTE Y DESCENDENTE TAMBIEN TIENE UN NUMERO CONSIDERABLE DE OTRAS MEJORAS QUE LA HACEN MAS ECONOMICA, MAS FACIL DE MONTAR, DE MAYOR DURACION Y CON UNA CALIDAD UNIFORME EN LA PRODUCCION EN SERIE.IT DESCRIBES AN IMPROVED UP AND DOWN PULLEY (1) FOR LIGHTING APPARATUS, CHARACTERIZED IN SO MUCH THAT IT INCLUDES A BRAKING GROUP CONSISTING OF A TOOTHED BRAKING WHEEL (9) TIGHTLY HOLDING BETWEEN THREADED CONNECTION MEDIA (11) ACOPL (5) OF THE DRUM TO ROLL THE SUSPENSION CABLE (27) OF THE UP AND DOWN PULLEY AND A THREADED RING LOCKING NUT (10) SCREWED IN SUCH CONNECTION MEDIA (11), WHICH, TOGETHER WITH ITS LOCKING NUT ( 10), IS THREADED IN A DIRECTION OPPOSITE TO THE ROTATION OF THE DRUM (4) DURING THE DESCENT OF THE CABLE (27), WHICH KEEPS SUCH A TOOTHED BRAKING WHEEL (9) ALWAYS TIGHT AND LOW-FRICTION, SELF-REGULATING, DURING THIS ITS USE, OFFSETTING ANY STRIP THAT IS FORMED OVER TIME. THE ASCENDING AND DESCENDING PULLEY ALSO HAS A CONSIDERABLE NUMBER OF OTHER IMPROVEMENTS THAT MAKE IT MORE ECONOMIC, EASIER TO ASSEMBLE, LONGER LASTING AND WITH UNIFORM QUALITY IN SERIAL PRODUCTION.
