A ceiling member 15, a floor member 16, and a side wall member 17 are fixed on the back side of the ceiling web 12L, floor web 13L, and side wall web 14K of the upper frame 12, lower frame 13, and left and right vertical frames 14 formed in this way. The ends of each frame 12, 13, and 14 are assembled into a rectangular shape via screw receivers 12N and 13Y to form a bay window frame 11, and the bay window frame 11 is attached to the existing sash window frame 1. Prior to this, a shielding member 1 is installed on the outdoor side of the existing exterior parting members 8 and 9 and the lower frame 3.
8, 19, and 20 are attached.

18 is an upper shielding member, which is attached along the outdoor surface of the upper exterior parting member 8,
At the lower end of the mounting piece 18A, a web 18B is formed that extends downwardly toward the outdoors at a predetermined length, and at the outer end of the web 18B, a dovetail groove 18C into which the airtight member 21 is fitted is formed. There is. Reference numeral 19 denotes a lower shielding member, which is attached to the outdoor side of the outdoor side mounting piece 3G of the lower frame 3, and extends from the lower end of the mounting piece 19A attached to the mounting piece 3G in an overlapping manner to the outdoor side. Web 1 extending horizontally at a predetermined length
9B is formed to have a substantially L-shaped cross section. Reference numeral 20 denotes a side shielding member, which is attached along the outdoor surface of the existing side parting member 9.
It is formed into a substantially L-shaped cross section by a mounting piece 20A along the outdoor surface and a web 20B extending to the outdoor side by a predetermined length, and an airtight member 2 is attached to the outdoor end of the web 20B.
A dovetail groove 20C into which 1 is fitted is formed.

Thus, from the outdoor side of the window opening W to which the shielding members 18, 19, and 20 are attached, the bay window frame 11 is exposed to the ceiling web 12L of the upper frame 12 that constitutes the bay window 11A.
Partition piece 2B of upper frame 2 of satsushi window frame 1 to the indoor side of
2C, 2D and slide grooves 2E, 2F, 2H
The adjustment piece 12M is located on the lower surface side of the upper shielding member 18, and the airtight member 21 is in contact with the upper surface of the upper shielding member 18, so that the indoor end side of the adjustment piece 12M is It is shielded. In addition, the floor web 13L of the lower frame 13 has its indoor side mounting piece 13M abutted against the upper end of the indoor piece 3J of the lower frame 3 on the outdoor side in an overlapping manner and is fixed by screws 23, so that the lower frame 3 can slide. The upper surface side of the web 3A is shielded, and the piece 13T of the adjustment piece 13R is in contact with the upper surface side of the web 19B of the lower shielding member 19 in an overlapping manner. Further, the indoor side of the side wall webs 14K of the left and right vertical frames 14 also abut against the partition pieces 4B, 4D of the vertical frame 4, and the door stop grooves 4E, 4F are shielded, and are fixed to the left and right vertical columns 7 by the mounting screws 21. At the same time, the adjustment piece 14N is brought into contact with the inside of the side shielding member 20 in an overlapping manner via the airtight member 21, and a bay window 11 is formed on the outdoor side of the window opening W.
The shoji sliding portion 11A of the first sash window frame 1 is formed at approximately the same level as the shoji sliding portion of the existing sash window frame 1. Further, the left and right ends 18D of the upper shielding member 18 extend laterally from the position of the web 20B of the side shielding member 20.

In addition, 24 in the figure is the shoji sliding part 11B of the bay window 11.
The glass shoji 25 built in 2007 is also a screen door, and the shoji sliding part of the existing sash window frame 1 and the shoji sliding part 11B of the bay window 11 are almost the same shape in these glass shoji 24 and screen door 25. The existing one is used because it is formed at the same level.

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

Now, the bay window 11 in this example is a bay window 11 to which an existing sash window frame 1 installed in the window opening W is attached, and the upper frame 12, lower frame 13 and left and right vertical frames 15 of the bay window frame are attached to the existing sash window frame 1. A ceiling web 12L, a floor web 13L, and a side wall web 14K extending into the sash window frame 1 are provided so that the inner surface of the sash window frame 1 can be installed in a covering manner, and an exterior facing material is provided around the periphery of the opening W. 8, 9 and the lower frame 3 are provided with shielding members 18, 19, 20 that are attached to their outdoor surfaces and overlap the adjustment pieces 12M, 13R, 14N formed on the outer periphery of the bay window frame. 1
3R, 14N and the shielding members 18, 19, 20 are constructed so that their overlapping widths can be adjusted in the indoor and outdoor directions. Therefore, each frame 12, 13 of the bay window 11,
Ceiling web 12L and floor web 13L provided in 14
And the side wall web 14K is the existing sash window frame 1.
The satsui window frame 1 is formed to a length that covers the inner surface of the
Since it is attached to the existing satsushi window frame 1, it can be installed without any special construction.
In addition, on the indoor side of the floor web 13L, a mounting piece 13M is provided that comes into contact with the indoor piece 3J provided on the lower frame 3 of the existing sash window frame 1. As a result, the bay window 11 can be attached to the existing sash window frame 1 in an extremely labor-saving manner. In addition, shielding members 18, 19, 20 are attached to the exterior parting members 8, 9 provided on the outdoor side of the window opening W and the shielding members 18, 19, 20 on the outdoor side of the lower frame 3,
Adjustment pieces 12M, 13R, and 14N are provided on the indoor side of each of the frames 12, 13, and 14 of the bay window 11 to abut on the inside of the shielding members 18, 19, and 20, respectively, in a superimposed manner. Even if the overhang width changes, the shielding members 18, 19, 20 and the adjustment piece 12
This variation can be absorbed by the overlapping parts with M, 13R, and 14N, and the dimensions of the bay window 11 in the expected width direction can be adjusted.
Since the indoor ends of R and 14N are shielded, the watertightness of the bay window 11 can be maintained. In addition, a drain recess 1 is provided on the indoor side of the shoji sliding portion 11B of the lower frame 13 of the bay window 11.
Since 3U is provided, the rainwater flowing along the front surface of the bay window 11 and the rainwater flowing down the lower frame 13 are drained by the draining recess 13U, and rainwater can be prevented from entering the indoor side, thereby improving rain protection. It has many features such as

It should be noted that each of the frame members illustrated in the above embodiments is entirely formed of a molded material formed by extrusion molding a light alloy material such as aluminum.

Now, the present invention is a bay window that is attached to an existing sash window frame installed in a window opening, and each frame of the bay window is extended into the existing sash window frame,
The inner surface of the sash window frame is provided so that it can be attached in an overlapping manner, and a shielding member is provided on the periphery of the opening that is attached to the outdoor surface of the same periphery and overlaps the outer periphery of the bay window frame. By being configured so that its overlapping width can be adjusted both indoors and outdoors, bay windows can be installed on existing sash window frames without any special construction work, and when installing bay windows, it is possible to adjust the overlapping width in both directions. Since the dimensions of the bay window in the expected width direction can be adjusted between them, installation work can be carried out extremely labor-savingly.
