The other side is fixed to the lower frame 2 of the window frame B so that it can be opened toward the outdoor side. A locking piece 4 (see Fig. 2) is provided horizontally protruding from the upper stile 3 of the window sash A on the inner side of the central room, and is secured by a locking device 5 attached to the upper frame of the window frame B. It's getting old.

するようになつている。 The locking device 5 is provided with a locking pawl 12 so as to be swingable, and by holding this locking pawl 12 in the position shown by the solid line in FIG. 2, the locking piece 4 is locked and the window sill is closed. A is formed so that it does not open, and the locking claw 12
The locking piece 4 is opened by sliding it toward the outside of the room.

るように構成している。 On the other hand, at the lower end of both vertical frames 7, 7 of window frame B, a fourth
As shown in the figure, the bracket 9 is fixed in the same manner as before or a little lower, and the vertical frames 6, 6 of the window shoji A are fixed.
A bracket 8' that protrudes further into the room than the bracket 9 is fixed to the upper end of the bracket. A stay damper 10 is attached to the tips of both brackets 8' and 9 so that force can be applied in the direction of tightening the window sash A.

本考案は前記のように構成したもので、窓障子
Ａを閉じた際には、窓障子Ａのブラケツト８′が

うに室内側への分力が作用して窓障子Ａを窓枠Ｂ
に押圧し、気密材に密着させることができる。 The present invention is constructed as described above, and when the window shoji A is closed, the bracket 8' of the window shoji A is located closer to the indoor side than the bracket 9 of the window frame B, so that the force of the stay damper 10 is increased. As shown in Figure 2, a force toward the indoor side moves the window shoji A to the window frame B.
It can be pressed tightly to make it adhere to the airtight material.

け開く。 When opening the casement window shoji A, the locking pawl 12 is swung toward the outdoor side to open the shoji A around the hinge 11 as the center of rotation, and the tip of the stay damper 10 is moved from vertical to the outdoor side. After that, it is opened by a predetermined angle by the force of the stay damper 10.

逆に窓障子Ａを閉じる際には、ステイダンパ１
０の先端が垂直方向よりも室内側に位置すれば、
自動的に閉じることになる。 Conversely, when closing window shoji A, use stay damper 1.
If the tip of 0 is located closer to the room than in the vertical direction,
It will close automatically.

尚、前記実施例においては窓障子Ａは下端を擺

る。 In the above embodiment, the sliding center of the window sash A was explained as being at the lower end, but the present invention is not limited to this, and the sliding center may be at the upper end or the side. Furthermore, the window shoji A is not limited to smoke exhaust windows, but can be used for various casement windows.
