PURPOSE: A windows frame of a sliding system is provided to variable form switching types of the windows frame and to improve the convenience by selectively performing a sliding type, a folding/unfolding type and a tilting type in one windows frame. CONSTITUTION: An additional internal windows frame having a switching device for a folding/unfolding or a tilting opening is combined with a sliding windows frame(10) with hinges. The switching device contains a vertical slider and a horizontal slider. The vertical slider moves upward and downward according to the rotating angle of a handle while vertically installing through the side of the internal windows frame. The horizontal slider receives the vertical moving force as the horizontal moving force by connecting with the upper part of the vertical slider while installing through the upper part of the internal windows frame. A supporting member(23) for supporting the lower part of the internal windows frame is installed in the sliding windows frame. An insertion slot(23a) is formed in the supporting member to insert and support an insertion piece combined with the lower end part of the vertical slider. |
