<Action of the hidden stile external movement single sliding window 1 of the embodiment>
Next, the operation of the hidden stile external moving single-pull window 1 of the embodiment configured as described above will be described with a focus on the discharge path of the dew condensation water generated when the shoji screen 6 is closed.

As shown in FIGS. 2 and 3, when the shoji 6 is moved to the vertical frame 4 side and closed, the indoor and outdoor areas are almost sealed by the hidden stile external movement single sliding window 1. Due to the temperature difference, dew condensation occurs on the internal sash 5 and the external sash 6.

In the hidden stile external movement single sliding window 1, the place where dew condensation is likely to occur is made of metal such as aluminum, which has high thermal conductivity and extends to the outside and the outside. A large amount of dew condensation is likely to occur in and around the front stile 63, and in particular, in and around the front sill hollow portion 63a that comes into contact with the warm air in the room.

FIG. 14 shows the main routes I to III when the dew condensation water in the hidden stile external movement single sliding window 1 of the embodiment is discharged to the outside of the room. Hereinafter, the routes I to III will be described separately.

(Drainage route I)
As shown in FIG. 14, the drainage path I mainly includes dew condensation water generated on the indoor side of the glass 66 around the door end stile 63, and when the outer sash 6 is closed, the opening attach 7 and the end fusagi member 8 are provided. Condensation water generated on the mullion side surface 63a2 (see FIG. 3 etc.) of the door tip stile hollow portion 63a located above the gap between the door and the door falls to the upper side surface 7a of the opening attach 7, and the opening attach 7 The path when the water is discharged from the gap between the glass and the end glass member 8 is shown.

In this case, since the water reservoir space 7c between the indoor standing piece 32 of the lower frame 3 and the outdoor standing portion 7b of the opening attach 7 is formed on the upper side surface 7a of the opening attach 7. The dew condensation water that has fallen on the upper side surface 7a of the opening attach 7 is collected in the water reservoir space 7c, and is prevented from flowing into the indoor side from the opening attach 7 to stain the indoor finish such as the frame and the indoor cloth. To prevent.

The dew condensation water collected in the water reservoir space 7c on the upper side surface 7a of the opening attachment 7 first falls below the gap between the opening attachment 7 and the end shoji member 8 as shown in the drainage route I shown in FIG. It falls on the inner sash installation surface 36 of the frame 3.

As shown in FIGS. 7 and 8, the inner sash installation surface 36 of the lower frame 3 is formed with the inner sash installation surface drainage hole 36c, and is formed in the gap between the opening attachment 7 and the end sash member 8. As shown in FIG. 14, a drain valve 36e is provided in the small drainage hole 36c on the side of the vertical frame 4 on the side where the shoji is installed. It falls on the middle surface 37 of the frame 3.

The dew condensation water that has fallen on the middle surface 37 of the lower frame 3 passes through the guide plate drain hole 37a1 of the guide plate 37a and the rail drainage portion 35a1 of the rail 35a due to the inclination of the middle surface 37, and finally the outdoor standing piece. It is discharged to the outside through the drain hole 33a for the outdoor standing piece of 33.

Path when dew condensation water generated on the indoor side surface 63a1 of the door tip stile hollow portion 63a located above the member 8 and the vertical frame side surface 63a3 (see FIG. 3 etc.) falls on the upper surface 8a of the end fuss member 8. Is shown.

As shown in FIGS. 10 to 12, a plurality of convex portions 8a1 and concave portions 8a2 having a width of about 2 mm and extending in the outdoor direction are alternately provided on the upper surface 8a of the end fusagi 8 to form an uneven shape. Since it is formed, it is possible to eliminate (decompose) the surface tension of the dew condensation water that has fallen on the upper surface 8a of the end fuss member 8 and prevent the dew condensation water from accumulating on the upper surface 8a of the end fuss.

The height of the convex portion 8a1 of the end fusagi member 8 is the same as or lower than that of the upper side surface 7a of the opening attach 7, and the convex portion 8a1 and the concave portion 8a2 are flat except for the protruding portion 8a3, and the concave portion 8a2 is on the indoor side. Since there is an indoor standing piece 32 of the lower frame 3 higher than the convex portion 8a1, the dew condensation water collected in the convex portion 8a1 and the concave portion 8a2 flows toward the outdoor side as shown in the drainage route II.

At that time, even if the lower end of the fusagi member retaining prevention piece 43 is exposed to dew condensation water, as shown in FIGS. Therefore, it is guided to the outdoor end portion of the upper surface 8a of the end end fussagi 8 so as to block the dew condensation water at the lower end portion thereof.

Then, when the dew condensation water reaches the outdoor end portion of the upper surface 8a of the end portion Fusagi 8, it flows downward from there and falls onto the airtight material mounting portion 36f of the lower frame 3.

Although the opening attach mounting piece 36a stands on the airtight material mounting portion 36f, as shown in FIG. 8, at the end close to the vertical frame 4, the opening attach mounting piece 36a is cut out for attachment mounting. While the one-sided drainage portion 36a1 is formed, the one-sided drainage portion 8e (see FIGS. 11 (b) and 12 (b)) is located in the end portion facing the attachment mounting piece drainage portion 36a1. Since the airtight material mounting portion 36f is provided, the dew condensation water that has fallen onto the airtight material mounting portion 36f is used for the drainage portion 36a1 for the attach mounting piece, the drainage portion 8e for the fusagi member, and the attachment mounting auxiliary piece as shown in the drainage route II. It flows through the drainage portion 36b1 to the internal obstacle installation surface 36 below the end fuss member 8.

After that, as in the case of the drainage route I, the drainage valve 36e is mounted and falls to the middle surface 37 of the lower frame 3 through the drain hole 36c on the installation surface of the internal obstacle, and the guide plate 37a is tilted due to the inclination of the middle surface 37 or the like. It is finally discharged to the outside through the guide plate drain hole 37a1 and the rail drainage portion 35a1 of the rail 35a, and finally through the outdoor standing piece drain hole 33a of the outdoor standing piece 33.

(Drainage route III)
As shown in FIG. 14, the drainage route III mainly shows the drainage route of the dew condensation water generated on the glass 66 on the indoor side of the shoji 6 and the dew condensation water generated on the indoor side surface of the lower stile 62.

As shown in FIG. 14, since the tips of the protruding pieces 91 and 92 of the blindfold member 9 are close to the lower stile 62 of the outer obstacle 6 but are not in contact with each other, they are generated in the glass 66 on the indoor side of the outer obstacle 6. The dew condensation water and the dew condensation water generated on the indoor side surface of the lower stile 62 pass through the gap between the indoor side surface of the lower stile 62 and the outdoor side surface of the opening attach 7, and the airtight material 36 g and the airtight material of the lower frame 3 are attached. It falls onto the portion 36f, and after that, as in the case of the drainage path II, the end fusagi member passes through the attachment mounting piece drainage portion 36a1, the fusagi member drainage portion 8e, and the attach mounting auxiliary piece drainage portion 36b1. 8 Flows to the lower internal obstacle installation surface 36, passes through the internal obstacle installation surface drain hole 36c, falls to the middle surface 37 of the lower frame 3, and further, the guide plate drain hole 37a1 of the guide plate 37a and the rail drainage portion 35a1 of the rail 35a. Finally, the water is discharged to the outside through the drain hole 33a for the outdoor standing piece 33 of the outdoor standing piece 33.
