When closing the lower shoji 3, the operation is performed so as to go back to the above procedure.

Next, regarding the construction method of the raising / lowering window 1, the work of attaching the upper shoji 2 to the frame body 10 will be mainly described.
First, the operator attaches and fixes the pair of shoji fixing brackets 62 and 62 to the vertical frames 13 and 14 of the frame body 10 by the screw members 603, respectively, as shown in FIG. 10 (first step). Here, as shown in FIG. 8, the operator arranges and attaches the shoji fixing bracket 62 so as to project toward the inside of the frame body 10.

Next, as shown in FIG. 8, in a state where the shoji fixing bracket 62 is attached to the vertical frame 14 of the frame body 10, the mounting bracket 61 of the upper shoji 2 is placed on the shoji fixing bracket 62 in the frame body 10. Lifting above the upper surface of the plate portion 63 (second step), the mounting bracket 61 of the upper shoji 2 and the upper lower stile 22 of the upper shoji 2 are placed on the upper surface of the mounting plate portion 63 of the shoji fixing bracket 62. (Third step). Then, in this state, as shown in FIG. 13, the mounting bracket 61 of the upper shoji 2 is fixed to the upper surface of the mounting plate portion 63 of the shoji fixing bracket 62 by using the screw member 601 (fourth step). When fixing the mounting bracket 61 of the upper sash 2 to the sash fixing bracket 62 with the screw member 601, the position of the upper sash 2 in the prospective direction is moved by moving the upper sash 2 in the prospective direction along the through slot 631a. Can be adjusted.
Here, the width (width in the finding direction) of the upper shoji 2 to which the mounting bracket 61 is attached (the length in the finding direction in which the upper shoji 2 and the mounting bracket 61 are combined) is determined by the left and right vertical frames 13 and 14. It is smaller than the inner width (inner length). Therefore, when the upper shoji 2 is built, the upper shoji 2 does not hit the left and right vertical frames 13 and 14, and the construction is easy.

According to this embodiment, the following effects are achieved.
In the present embodiment, the upper stiles 21, 31, the lower stiles 22, 32 and the left and right vertical stiles 23, 24, 33, 34 constituting at least one of the upper stile 20 and the lower stile 30 are made of resin material. The upper stiles 21, 31, the lower stiles 22, 32 and the left and right vertical stiles 23, 24, 33, 34 have the same cross-sectional shape in the direction orthogonal to the extending direction.

As a result, any one of the upper upper stile 21, the upper lower stile 22, the upper vertical stile 23, 24, the lower upper stile 31, the lower lower stile 32, and the left and right lower vertical stiles 33, 34 formed of the resin material. When they are joined by welding, they are easy to weld because they have the same cross-sectional shape. Conventionally, in the raising and lowering window 1 having a flat slide structure, since various members are attached to the stile, the cross-sectional shape tends to be complicated. Therefore, particularly in the raising and lowering window 1 having a flat slide structure, the upper upper stile 21, the upper lower stile 22, the upper vertical stile 23, 24, the lower upper stile 31, the lower lower stile 32, and the left and right sash windows 1 made of a resin material. Making the lower vertical frames 33 and 34 have the same cross-sectional shape is particularly effective in that welding is easy.

Further, in the present embodiment, in the closed state, an elastically deformable annular packing 7 is provided between the upper frame 20 and the lower frame 30 and the frame 10 over the entire inner peripheral edge of the frame 10. Be prepared.
Therefore, regarding the upper upper stile 21, the upper lower stile 22, the left and right upper vertical stiles 23, 24, the lower upper stile 31, the lower lower stile 32, and the left and right lower vertical stiles 33, 34 having the same cross-sectional shape. The shape of the portion with which the annular packing 7 abuts can be the same. As a result, the contact state of the annular packing 7 is stably maintained, and the upper upper stile 21, the upper lower stile 22, the left and right upper vertical stiles 23, 24, the lower upper stile 31, the lower lower stile 32, and the left and right The airtightness between the stile 40 and the frame 10 can be further improved in any of the lower vertical stiles 33 and 34.

Further, in the present embodiment, the raising / lowering window 1 includes a part of the upper glass 200 and the lower glass 300, and a part of the upper stiles 21, 31, the lower stiles 22, 32 and the left and right vertical stiles 23, 24, 33, 34. The glass adhesive portion 50 for adhering and fixing the above is provided.

Therefore, in the upper upper stile 21, the upper lower stile 22, the left and right upper vertical stiles 23, 24, the lower upper stile 31, the lower lower stile 32, and the left and right lower vertical stiles 33, 34 having the same cross-sectional shape, It is not necessary to form the adhesive portion between the glass 500 and the stile 40 over the entire circumference of the upper glass 200 or the lower glass 300. The reason is that the upper upper stile 21, the upper lower stile 22, the left and right upper vertical stiles 23, 24, the lower upper stile 31, the lower lower stile 32, and the left and right lower vertical stiles 33, 34 having the same cross-sectional shape. This is because the shape of the groove 40a in which the glass 500 is arranged in the stile 40 can be the same, so that the strength of the joint portion between the stile 40 and the glass 500 is secured. As a result, the strength of the joint portion between the stile 40 and the glass 500 can be ensured only by adhering and fixing the portion between the stile 40 and the glass 500 with the glass adhesive portion 50. Further, since the glass adhesive portion 50 adheres and fixes a part between the stile 40 and the glass 500, the stile 40 can be reused when the glass 500 is replaced. Further, in particular, when the stile 40 is arranged at a substantially central portion in the longitudinal direction, the strength of the joint portion between the stile 40 and the glass 500 can be stabilized, and the airtightness can be further improved.
