Although this embodiment is configured in this way, for example, by forming the screw hole 69 at a position closer to the airtight member 65, the upper ends of the airtight members 55, 65 can be made airtight by screwing the screw hole 69 and the screw 7F. The airtightness may be improved by further making airtight contact with the material 35.
In addition, since the airtight materials 55 and 65 are held down by the holding pieces 637 and 237, the thickness of the airtight materials 55 and 65 in the X-axis direction is set to a size that can fill the space between the inner circumferential prospective surface portion 54 and the outer circumferential prospective surface portion 63. Also, the space between the inner circumference prospective surface portion 64 and the vertical frame prospective piece portion 233 can be made smaller than the dimension that can be filled, thereby achieving thinning.

As shown in FIG. 3, the new vertical frame 24 is configured in the same manner as the new vertical frame 23, and is arranged in opposite left and right directions. The space between the existing vertical frame 14 and the renovated vertical frame 50 is sealed by a sheet material 93. The vertical frame attachment 100, the renovated vertical frame 50, and the sight adjustment frame 60 here are the same as the vertical frame attachment 100, the renovated vertical frame 50, and the sight adjustment frame 60 arranged between the existing vertical frame 13 and the new vertical frame 23. The left and right sides are arranged in opposite directions.
Note that the airtight members 55 and 65 are in airtight contact with the airtight members 35 and 45 to form an airtight line continuous around four times. The sheet materials 91, 92, and 93 constitute a four-circle continuous seal line.

[Summary of the present invention]
The renovated sash of the present invention is a renovated sash in which a new frame is installed in an opening of an existing frame, and a renovated frame that can be attached to the new frame is arranged on the inner circumferential side of the existing frame, and the renovated frame and at least one sight adjustment frame is arranged between the new construction frames, the outer peripheral side of the sight adjustment frame has a first attachment part that can be attached to the refurbished frame, and the inner peripheral side of the sight adjustment frame has a first attachment part that can be attached to the refurbished frame. It is characterized in that it has a second attachment part that can be attached to either the newly installed frame or the first attachment part.
According to the renovated sash of the present invention, by arranging the sight adjustment frame between the renovated frame and the new frame, the sight size between the existing frame and the new frame can be adjusted to a greater extent than when a new frame is attached to the renovated frame. can. Therefore, by attaching the renovated frame directly to the new frame or by placing at least one spot adjustment frame between them, the existing frame and the new frame can be adjusted according to the various opening width dimensions between the existing frames. It is possible to adjust the size of the gap between the frames, eliminate the need to prepare multiple types of refurbishment frames, and reduce costs.

In the renovated sash of the present invention, a base material is attached to the newly installed frame, an end of the base material is arranged to cover an end of the renovated frame and the sight adjustment frame, and the end of the base material is arranged to cover the end of the renovated frame and the sight adjustment frame. A sealing material may be installed between the end of the substrate and the end of the base material.
According to such a configuration, the ends of both the renovation frame and the sight adjustment frame can be closed with the sealing material described above.

In the renovated sash of the present invention, the renovated frame is a renovated vertical frame to which the sight adjustment frame can be attached, the newly installed frame includes a newly installed upper frame, an upper frame base material is attached to the newly installed upper frame, and the renovated frame is a renovated vertical frame to which the sight adjustment frame can be attached. The end of the upper frame base material is disposed to cover the upper ends of the renovated vertical frame and the sight adjustment frame, and between the upper ends of the renovated vertical frame and the sight adjustment frame and the end of the upper frame base material. A sealing material is installed, the position adjustment frame has a fixed part that is fastened to a fixture that fixes the upper frame base material, and the sealing material is compressed by the fastening of the fixing tool and the fixed part. Good too.
According to such a configuration, for example, when a new vertical frame is directly attached to a renovated vertical frame, the dimension between the existing vertical frame and the new vertical frame is small, so the upper frame base material cannot be attached to the new upper frame. , it is possible to properly compress the sealing material between the upper frame base material and the renovated vertical frame without fixing the upper frame base material to the renovated vertical frame with fixing devices, but the sealing material between the renovated vertical frame and the new vertical frame When placing a position adjustment frame, the position size between the new vertical frame and the renovated vertical frame becomes large, making it difficult to compress the sealing material between the renovated vertical frame or position adjustment frame and the upper frame base material. By fastening the fixture to the fixed portion of the positioning adjustment frame, the sealing material can be appropriately compressed. Therefore, the sealing performance between the upper ends of the renovated vertical frame and the sight adjustment frame and the ends of the upper frame base material can be maintained.

In the refurbished sash of the present invention, the sight adjustment frame may have an outdoor facing surface portion, an indoor facing surface portion, an outer peripheral facing surface portion, and an inner peripheral facing surface portion, and the fixed portion may be formed on the outer peripheral facing surface portion.
According to such a configuration, the fixed part is formed on the outer circumferential prospective surface of the sight adjustment frame, so compared to, for example, a case where the fixed part is formed on the inner circumferential prospective surface, the fixed part is formed on the outer peripheral prospective surface from the newly installed vertical frame side. The upper frame base material can be fixed at a distance to the side. Therefore, by fastening the fixture and the fixed part, the sealing material can be more appropriately compressed and the sealing performance can be improved.

In the renovated sash of the present invention, an airtight material may be provided between the renovated frame and the sight adjustment frame, and between the sight adjustment frame and the newly installed frame, along each frame.
According to such a configuration, it is possible to prevent rainwater, etc. from entering the indoor side from the connection point between the fixed part of the sight adjustment frame and the fixture by the airtight material located on the indoor side with respect to the fixed part. .
