PURPOSE: A window system is provided to reduce the material costs of a curved rail by assembling side rail units in a linear rail unit. CONSTITUTION: A window system comprises a rail(101) and rollers(102). The rail comprises a linear rail unit(103), assembly units(104), and side rail units(105). The linear rail unit is extrusion-molded in a linear shape. The assembly units are formed on the linear rail unit in a groove shape. The side rail units are coupled to the assembly units and guide the rollers when a window frame is horizontally moved. The rollers are slid along the linear rail unit. |
