Japanese Patent No. 4093417

However, in the modified sash described in Patent Document 1, the vertical position adjustment width of the lower frame base is limited to the vertical length dimension of the elongated hole formed in the vertical plate, so that the length of the elongated hole is limited. It is not possible to adjust the position of the lower frame base in the vertical direction with respect to the mounting portion beyond the dimensions.
For this reason, even if the vertical position of the lower frame base with respect to the mounting portion is adjusted to the maximum width, the mounting portion does not reach the mounting position with respect to the lower rail, so that the indoor side portion (indoor portion) and the lower portion of the existing lower frame When the step in the vertical direction with the rail (outdoor part) is large, it is difficult to attach the lower base material to the existing lower frame.

An object of the present invention is to provide a refurbished sash in which a new lower frame can be installed corresponding to a step in the vertical direction between the indoor portion and the outdoor portion of the existing lower frame.

[Effects of the first and second embodiments]
(1) In the first and second embodiments, the refurbished sash 1 is a refurbished sash 1 in which a new frame 20 is installed on the inner peripheral side of the existing frame 10 remaining in the building frame 2, and the existing frame 10 is already installed. A lower frame support metal fitting 50 is arranged between the lower frame 12 and the new lower frame 22 of the new frame 20, and the lower frame support metal fitting 50 is attached to the support member 51 that supports the new lower frame 22 and the support member 51. The support member 51 includes an adjustment member 61 to be attached, and the support member 51 has a prospective piece portion 52 and an attachment piece portion 53, and the adjustment member 61 has a short side 613 (first contact side) thereof as an existing lower frame 12. The first mounting state (see FIGS. 5 and 6) in which the mounting piece 53 is vertically adjustable in the first mounting direction and the long side 612 (second contact side) of the adjusting member 61. Is configured to be switchable between the second mounting state (see FIGS. 3 and 4) in which the mounting piece 53 is vertically adjustable in the second mounting direction in contact with the existing lower frame 12, and the first mounting state. The maximum dimension L2 from the lower side 532 to the short side 613 of the mounting piece portion 53 in the second mounting state is longer than the maximum dimension L3 from the lower side 532 to the long side 612 of the mounting piece portion 53 in the second mounting state. And.
Since it has the above configuration, in the first mounting state where the adjusting member 61 is mounted on the mounting piece 53 of the support member 51 in the first mounting direction, only the maximum dimension L2 from the lower side 532 to the short side 613 of the mounting piece 53 is obtained. The position of the adjusting member 61 can be adjusted downward from the mounting piece 53.
On the other hand, in the second mounting state in which the adjusting member 61 is mounted on the mounting piece 53 of the support member 51 in the second mounting direction, the adjusting member 61 is provided by the maximum dimension L3 from the lower side 532 to the long side 612 of the mounting piece 53. The position can be adjusted downward from the mounting piece 53.
Here, since the maximum dimension L2 in the first mounting state is longer than the maximum dimension L3 in the second mounting state, the position of the adjusting member 61 can be adjusted further downward than in the second mounting state in the first mounting state. Therefore, even if the position of the adjusting member 61 is adjusted to the lowermost position in the second mounting state, the indoor portion and the outdoor portion of the existing lower frame 12 are so that the long side 612 does not reach the outdoor portion of the existing lower frame 12. Even when the step in the vertical direction is large, the short side 613 can be brought into contact with the existing lower frame 12 in the first mounting state. As a result, the lower frame support metal fitting 50 can be installed on the existing lower frame 12, the new lower frame 22 can be supported, and the new lower frame 22 can be installed corresponding to the step between the indoor portion and the outdoor portion of the existing lower frame 12. ..

By adjusting the position to, it can be accommodated without protruding below the lower side 532 of the mounting piece 53.
(5) Two adjusting elongated holes 54A and 54B are formed in the mounting piece portion 53, three screw holes 62A, 62B and 62C are formed in the adjusting member 61, and three first mounting holes 63 are formed. Of the screw holes 62A, 62B, 62C, the second mounting holes 64 are composed of two screw holes 62A, 62B located along the direction parallel to the short side 613, and the second mounting holes 64 are the three screw holes 62A, 62B, Of 62C, it is composed of two screw holes 62B and 62C located along a direction parallel to the long side 612, and the first mounting hole 63 and the second mounting hole 64 are three screw holes 62A, 62B, 62C. One of the screw holes 62B is shared.
Therefore, by sharing the screw hole 62B between the first mounting hole 63 and the second mounting hole 64, the number of screw holes formed in the adjusting member 61 can be reduced, the hole processing can be simplified, and the hole processing can be simplified. , The rigidity of the adjusting member 61 can be improved.
(6) An insertion hole 56 through which a drill screw 55 fixed to the adjusting member 61 can be inserted is formed in the mounting piece portion 53 of the support member 51.
