Description

[Detailed description of the invention] A bay window that extends outward from a building has a structure that is significantly different from that of a general window frame.

In other words, because a bay window is structurally composed of wing window frames on the left and right sides and a front window frame at the front, each window frame, especially a part of the front window frame, also constitutes a part of the wing window frame. Because of this, its cross-sectional shape is unique to bay windows, and therefore ordinary window frames cannot be used as window frames for bay windows.

Therefore, in the past, it was necessary to form a window frame specifically for the bay window, which had the disadvantage of being quite expensive if not mass produced.

The present invention focuses on the above-mentioned difficulties and aims to reduce the manufacturing cost by making it possible to use a general window frame as a part of the window frame for the 11 bay windows.

Below, one embodiment of the present invention will be explained with reference to the drawings.

is attached in a fixed state.

Therefore, according to the present invention, by making the structure of the facing surface of the window frame 14 for general double sliding and the window frame 21 for closing the window the same as that of the protruding side mullion frame 4, these window frames 14 and 21 are In each case, the flat surface 13 for attaching the window frame of the mullion frame 4 and the engaging part 10 for positioning,
Since it is possible to attach and position the window frame 11 and fix it to the screw pockets N2 and 12 with screws, the mullion frame 4 can be used as a common member to attach the window frame 1.
4.21 can be selectively attached to configure the window structure of the front window portion 9 to be a sliding window or a fixed window.

The above window frames 14 and 21 show the structure of the entire window frame, especially the window side frames, and therefore the upper frame portion and the lower frame portion must also be replaced and used according to the above selection of the window structure.

To this end, as shown in FIG. 4, the upper window frame 27 of the sliding window has L-shaped positioning flange pieces 29, 29 protruding outward (upward) from both the indoor and outdoor lines of the straight wall portion 28. At the same time, the window inner frame 1 is attached inward (downward) to the straight wall portion 28.
