PURPOSE: A roll screen system for protection against wind is provided to improve dust cutoff effects by minimizing the gap between the horizontal edges of a roll screen and side rail members. CONSTITUTION: A roll screen system for protection against wind comprises a spring roll gear box(100), a roll screen(200), and side rail members(300). The spring roll gear box has a slit groove. One end of the roll screen is rolled inside a pipe body of the spring roll gear box, and the other end is drawn out of the slit groove. The side rail members support and guide the horizontal edges of the roll screen drawn out of the spring roll gear box. |
