PURPOSE: A one-cord type blind system is provided to increase user convenience, to minimize operating load, and to improve operating efficiency by controlling uplift operation and a slop of a slat with one adjusting cord. CONSTITUTION: A one-cord type blind system comprises a supporting frame, a clutch, a rotary shaft, an opening and closing device, and multiple slats. The opening and closing device comprises a slat lifting unit (10), a slat opening and closing unit (50), a rotor (60), and a driving clutch (70). The slat lifting unit is rotatably installed in the supporting frame in order to lift the slat. The slat opening and closing unit is installed to face the slat lifting unit and regulates a slope by rotary moving the slat. The rotor is built in the slat opening and closing unit and is combined with the rotary shaft. The driving clutch is externally inserted into the rotor and is movable back and forth along the rotating direction of the rotor. |
