Description

[Detailed Description of the Invention] The present invention relates to a bay window in which a window frame protrudes from the outside of a building to the outside, and an inner window frame is installed at the proximal end of the window frame.

Such bay windows were provided due to the need for double-glazed windows in cold regions, but conventional bay windows have an upper horizontal frame, a lower horizontal frame, and a vertical frame that make up the window frame of the bay window. Since the frames are formed from separate frame materials, that is, frame materials with different cross-sectional shapes, the manufacturing cost is inevitably high.

In view of the above points, the present invention has been developed by making the upper and lower horizontal frames and the left and right vertical frames constituting the window frame of a bay window have the same cross-sectional shape, thereby making it possible to use the same frame material and making the window frame cheaper.
