Therefore, a plurality of glass shoji 36 installed on the sliding frame part 2 of the bay window S,
37, when the bay window S is closed, the width of the glass shoji 37 located at both ends of the sliding frame 2 is made smaller than the width of the other glass shojis, and the width of the sliding frame 2 is Shutter 48 of shutter frame 38 attached to the front
And the door pocket 40 is a glass shoji 37 with a small width.
Since the door pocket 40 is formed to have a building width and a frame width that are approximately equivalent to , and the door pocket 40 is provided in front of the closed position of the glass shoji 37, which has a small building width, The function of the bay window can be improved by attaching the shutter frame 2, and even if the shutter frame 2 is attached, the shutter can be opened from the indoor side by sliding the glass shoji 37, which has a small width. It has many features such as being able to open and close the 48 with great ease.

In addition, in this example, two glass shoji 3
6 and 2 glass shojis 37 with a small width are erected, and door pockets 40 are provided on the outdoor side of the glass shoji 37 with a small width, that is, on both sides of the shutter frame 38, but the present invention is not limited to this. , the door pocket 40 may be provided on one side. Further, each frame member and frame member illustrated in this embodiment are all formed from a molded material extruded from a light alloy material such as aluminum.

Now, the present invention is a bay window to which a shutter can be attached, in which a shutter frame having a door pocket is attached to the front of the sliding frame part, and a plurality of glass shojis are attached to the sliding frame part. The glass shojis are erected in a sliding manner, and among the plurality of glass shojis, the erected width of the glass shoji located at both ends or one end of the sliding frame portion is smaller than the erected width of the other glass shojis. At the same time, the shutters and door pockets of the shutter frame are formed to have a built-in width and frame width approximately corresponding to the glass shoji with a small built-in width, and the door pockets are provided in the closed position of the glass shoji with a small built-in width. By sliding the glass shoji with a small installation width and opening and closing the shutter from the indoor side of the door pocket, the shutter frame device can be attached to the front of the sliding frame as necessary. This makes it possible to improve the function of the bay window, and even with the shutter frame attached, the shutter can be opened and closed extremely easily from the indoor side by sliding the narrow shoji screen. This is an extremely practical idea as a bay window that can be fitted with a shutter.
