A blind apparatus including head box, a bracket for mounting the blind apparatus on a window, a plurality of vertically spaced parallel slats supported by ladder cords connected to a rotary drum located in a head box, a tilter device for tilting the slats and including a tilter input shaft, a tilter for transmitting the rotation of the tilter input shaft to the rotary drum, and a hollow rotating operation rod coupled to the tilter input shaft, slat lifting cords, a stopper device disposed in the head box for restraining the lifting cords from moving, and a stopper releasing cord connected at its one end to the stopper and extended through the interior of the rotating operation rod and the grip at a free end of the operation rod.

Blind apparatus

A blind includes a plurality of horizontal angle-shaped slats supported by ladder-shaped supporting cords, which extend vertically from a bottom of a head box of the blind, and lifting cords, which extend from the head box through cord passing slots in the slats to a bottom rail of the blind, for raising and lowering the slats. Each of the slats has a first, porous and semi-light-transmitting part extending from an apex portion of the slat to one side edge of the slat and a second, non-porous and non-light-transmitting part extending from the apex portion of the slat to the another side edge of the slat. The cord passing slots are formed either in first parts of the plurality of slats or in the second parts of the plurality of slats, and extend from apex portions of respective slats to one edges of the slats or to another edges of the slats, respectively.
