[Summary of the present invention]
The refurbished sash of the present invention is a refurbished sash in which a new frame is installed in the opening of the existing frame, and a refurbished frame that can be attached to the new frame is arranged on the inner peripheral side of the existing frame. At least one finding adjustment frame is arranged between the new frame, the outer peripheral side of the finding adjustment frame has a first mounting portion that can be attached to the refurbished frame, and the inner peripheral side of the finding adjustment frame is. It is characterized by having a second mounting portion that can be mounted on either the new frame or the first mounting portion.
According to the refurbished sash of the present invention, by arranging the finding adjustment frame between the refurbished frame and the new frame, the finding dimension between the existing frame and the new frame is greatly adjusted as compared with the case where the new frame is attached to the refurbished frame. can. For this reason, by attaching the refurbished frame directly to the new frame or arranging at least one finding adjustment frame between them, the existing frame and the new frame can be set according to various opening width dimensions between the existing frames. It is possible to adjust the found dimensions of the space, eliminate the need to prepare multiple types of refurbishment frames, and reduce costs.

In the refurbished sash of the present invention, a base material is attached to the new frame, and the end portion of the base material is arranged so as to cover the refurbished frame and the end portion of the finding adjustment frame, and the refurbished frame and the finding adjustment frame are arranged. A sealing material may be installed between the end portion of the base material and the end portion of the base material.
According to such a configuration, both ends of the refurbished frame and the finding adjustment frame can be closed by the above-mentioned sealing material.

In the refurbished sash of the present invention, the refurbished frame is a refurbished vertical frame to which the finding adjustment frame can be attached, the new frame is provided with a new upper frame, and the new upper frame is attached with an upper frame base material. The end portion of the upper frame base material is arranged so as to cover the upper ends of the refurbished vertical frame and the finding adjustment frame, and between the upper ends of the refurbished vertical frame and the finding adjustment frame and the end portion of the upper frame base material. A sealing material is installed, and the finding adjustment frame has a fixed portion to be fastened to a fixing tool for fixing the upper frame base material, and the sealing material is compressed by fastening the fixing tool and the fixed portion. May be good.
According to such a configuration, for example, when the new vertical frame is directly attached to the refurbished vertical frame, the found dimension between the existing vertical frame and the new vertical frame is small, so the upper frame base material should be attached to the new upper frame. So, it is possible to properly compress the sealing material between the upper frame base material and the refurbished vertical frame without fixing the upper frame base material to the refurbished vertical frame with a fixative, but between the refurbished vertical frame and the new vertical frame. When arranging the finding adjustment frame, the finding dimension between the new vertical frame and the refurbished vertical frame becomes large, and it becomes difficult to compress the sealing material between the refurbished vertical frame and the finding adjustment frame and the upper frame base material. By fastening the fixture to the fixed portion of the finding adjustment frame, the sealing material can be appropriately compressed. Therefore, the sealing property between the upper end of the refurbished vertical frame and the finding adjustment frame and the end portion of the upper frame base material can be maintained.

In the refurbished sash of the present invention, the finding adjustment frame has an outdoor finding surface portion, an indoor finding surface portion, an outer peripheral prospective surface portion, and an inner peripheral prospective surface portion, and the fixed portion may be formed on the outer peripheral prospective surface portion.
According to such a configuration, since the fixed portion is formed on the outer peripheral prospective surface portion in the finding adjustment frame, the outer periphery is formed from the newly installed vertical frame side as compared with the case where the fixed portion is formed on the inner peripheral prospective surface portion, for example. The upper frame base material can be fixed at a position away from the side. Therefore, the sealing material can be more appropriately compressed by fastening the fixing tool and the fixed portion, and the sealing property can be improved.

In the refurbished sash of the present invention, an airtight material may be provided along each frame between the refurbished frame and the finding adjustment frame and between the finding adjusting frame and the new frame.
According to such a configuration, it is possible to prevent rainwater or the like from entering the indoor side from the fastening portion between the fixed portion of the finding adjustment frame and the fixture by the airtight material located on the indoor side with respect to the fixed portion. ..
