Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the bay window 1 of this example is made by connecting a window frame body 2 and a roof plate 15 and a bottom plate 17 made of cast molded aluminum light alloy material through support metal fittings 13, 19, and 21. In particular, the support metal fitting 13 is one piece 13
A is screwed together with the upper and lower frames 5 and 6 of the front window part 3 of the window frame body 2 and the left and right directions 7, and the upper and lower frames 9 and 10 of the side window part 4 and the vertical frame 8 with the frame screws 11. At the same time, screw receivers 16a, 16c, 18 are provided on the lower surface of the roof plate 15 and the upper surface of the bottom plate 17.
a, 18c are provided, and the other piece 13b of the support fitting 13 is secured with a screw 20. Therefore, since the supporting metal fittings 13 are assembled in advance to the window frame body 2 when it is framed, the roof plate 1
5 and the bottom plate 17 can be performed extremely labor-savingly.
Screw receiving parts 16a, 16b, 16c, 18 with
Since a, 18b, and 18c are metal materials, the screws 20
It has many features such as significantly increasing the fastening strength and increasing the framework strength, making it possible to create a robust and stable framework.

It should be noted that each of the frame members illustrated in the above-described embodiments is all formed of a molded material extruded from a light alloy material such as aluminum.

(Effects of the invention) The present invention is a bay window in which a window frame body, a roof plate, and a bottom plate are connected via a support metal fitting, and the support metal fitting has one side thereof connected to a mullion of the window frame body. The vertical frame and the horizontal frame including the frame are screwed together with the frame using frame screws, and a screw receiving part is provided on the lower surface of the roof plate and the upper surface of the bottom plate to screw the other side of the support metal fitting. It is something. Therefore, since the supporting metal fittings are pre-assembled to the window frame at the time of framing, the connection work with the roof plate and the bottom plate can be carried out extremely labor-savingly. Since it is made of metal, the fastening strength with screws is significantly increased, and the frame strength is also increased, resulting in a sturdy and stable framework, making it an extremely practical idea for bay windows.
