Blind apparatus

A blind apparatus, comprising:

• a head box having opposite longitudinal side edges;
• a bracket for mounting said head box on a wall or the like and having means for retaining said opposite longitudinal side edges;
• a bottom rail vertically spaced from said head box;
• a plurality of vertically spaced slats extending substantially parallel to each other in a space between said head box and said bottom rail;
• a plurality of ladder cords extending between said head box and said bottom rail for supporting said plurality of slats;
• a rotary drum located inside said head box, said ladder cords being connected, at one end thereof, to said rotary drum for being wound on and rewound from said rotary drum upon rotation of said drum in opposite directions;
• tilter means for tilting of said plurality of seats and including:
• a tilter input shaft extending downward at one end of said head box;
• a tilter disposed in said head box for transmitting rotation of said tilter input shaft to said rotary drum;
• a hollow rotating operation rod coupled to said tilter input shaft for rotating same,
• a universal joint for coupling said hollow rotating operation rod to said tilter input shaft, and
• a hollow grip provided at a lower end of said operation rod for rotating same;
• lifting cords connected at one end thereof to said bottom rail and extending through holes formed in said plurality of slats for lifting a blind formed by said plurality of slats, said lifting cords extending through said head box and then through an interior of said hollow rotating operation rod and said hollow grip, and said lifting cords having another end thereof extending from a lower end of said hollow grip;
• a stopper device located in said head box for preventing said lifting cords from moving;
• and
• a stopper device releasing cord connected at one end thereof to said stopper device and extending through the interior of said hollow rotating operation rod and said hollow grip;
• wherein said stopper device includes:
• a shopper case fixed to said head box and opened at an upper end thereof,
• a cord nozzle provided at one end of said stopper case,
• means for preventing movement of said cord nozzle in a longitudinal direction,
• a cord stopper provided on said stopper case, means for enabling movement of said cord stopper in the longitudinal direction and for preventing rotation of said cord stopper, and
• a spring for biasing said cord stopper toward said cord nozzle;
• and
• wherein said cord stopper includes:
• a bottom portion fitted to said stopper case and having a bore through which said lifting cords extend,
• a conical end projecting from said bottom portion and cooperating with said cord nozzle for clamping the lifting cord therebetween,
• a first insertion hole extending from said bottom portion to an outer peripheral surface of said conical end near an apex of said conical end, and
• a second insertion hole formed in said bottom portion radially outwardly of said first insertion hole, said stopper release cord extending through said first insertion hole, said outer peripheral surface of said conical end, and then through said second insertion hole so as to be fastened to said cord stopper at a side of said bottom portion opposite said conical end.
