Fix the upper frame 1A and the vertical frame 1c to the outdoor sides with screws so that the openings thereof face the inner periphery, and then attach the auxiliary material 18.
The lower stile 3 is attached to the lower end between the vertical frame 1c and the vertical frame 2.
The inner wall 3a is extended downward longer than the outer wall 3b,
The flexible plate 7 is exposed below the outer wall 3b from inside the lower stile 3, and both ends of the flexible plate 7 are screwed to the vertical frame 1c and the vertical frame 2, and the middle part of the flexible plate 7 is Either the inner wall 3a and the outer wall 3b of the lower stile 3 can be bent in the indoor/outdoor direction, or the lower stile 3 can be composed of two members, the inner wall member 3A and the outer wall member 3B. Connecting pieces 4a, 4 that are vertically different from each other in 3B
b, and engaging portions 5a, 5b of the connecting pieces 4a, 4b are provided, and the flexible plate 7 is integrally molded on the lower connecting piece 4, and the indoor side and the outdoor side of the connecting piece 4 are provided so that the flexible plate 7 remains. By cutting out the middle part of the flexible plate 7, the flexible plate 7 can be bent in the direction of the interior and exterior within the area where the cutout 6 is formed.

The proposed single-sliding window has the above-mentioned structure, with the glass G being fitted on the outside side, the shoji S being fitted on the indoor side so that it can be opened and closed, and the shoji S on the side where the glass G is not fitted.
Since it is opened by pulling in the shoji S, the shoji S can be inserted and removed from the indoor side. In addition, the wind stop block 10 inserted into the smoke return 21 of the vertical frame 2 is a shoji S
If it is removed, it can rise along the smoke return 21, so even if dust accumulates on the indoor side of the glass-fitting part, it can be easily swept out. A glass fitting part 8 provided on the outdoor side of the window frame 1 is connected to the upper frame 1A and the vertical frame 1.
Fitting grooves 8a, 8c, and fitting grooves 8d provided in c.
Since it is constituted by the vertical frame 2 and the lower stile 3 having the shape 8e, the insertion portion 8 can be formed on either the left or right side of the vertical frame 2. In addition, the lower stile 3 constituting the glass insertion part 8 is provided with a flexible plate 7 that is exposed below the outer wall 3b from inside the lower stile 3 and can be bent in the indoor-outdoor direction. When the air pressure becomes lower than the indoor side, the middle part of the flexible plate 7 is pressed toward the outdoor side due to the pressure difference, and the tight material T provided at the lower part of the flexible plate 7 separates from the lower frame 1B, and from the gap. When the rainwater accumulated on the indoor side flows out to the outdoor side and the outside pressure becomes higher than the indoor side, the middle part of the flexible plate 7 is pressed toward the indoor side due to the pressure difference, and the flexible plate 7 The tight material T provided at the bottom comes into pressure contact with the lower frame 1B to prevent air from blowing into the room from outside. Furthermore, the block 10 inserted into the smoke return 21 of the vertical bone 2 is
When the shoji S is closed, the space A generated between the vertical rib 2 below the lower end of the stile B and the forming part of the lower frame rail 1b is closed, and wind and rain are prevented from blowing into the room from the space A.

Therefore, in the single-sliding window of the present invention, the glass is attached tightly to the left or right half of the outdoor side, and the shoji is inserted into the indoor side so that it can be opened and closed, so the shoji can be easily inserted and removed from the indoor side. can do. Moreover, by making the shoji an internal fitting type, even if a space is created between the vertical ribs below the lower end of the stile and the bottom rail forming part, the space can be filled by the wind block that is inserted into the vertical ribs. Since it is closed by twisting, it is possible to prevent wind and rain from blowing into the room from the space, and even if rainwater accumulates on the indoor side from the bottom rail, the rainwater is drained from the notch in the bottom rail to the side where the glass is fitted. The lower stile that makes up the glass insertion part is equipped with a flexible plate that bends indoors and outdoors due to the difference in air pressure, so when the outside air pressure becomes lower than indoors, the flexible plate bends outdoors. During this time, water is drained outside through the gap. Furthermore, even if dust accumulates on the recess side of a shoji that is attached to the glass, it can be easily swept away because the shoji can be removed from the room and the wind block can be raised along the smoke return of the vertical frame. In addition to the above-mentioned features of easy handling, the sliding window of this invention has beneficial effects in a wide range of applications from high-rise buildings to ordinary residences.
