Airtight pieces 33 are provided on the outdoor side and indoor side of the groove 29 to abut against the upper end of the upper stile 23.
The rectifying piece 30 of the upper frame 20 extends below the communication part 28 of the upper stile 23, and a space 34 between the rectifying piece 30 and the upper stile 23 communicates with the communicating part 28. The rectifying piece 30 is configured to cause air flowing out from the communication portion 28 to flow downward, or to guide air rising along the shield (shoji) 19 to the communication portion 28 . As a result, the air rising along the outdoor side surface of the shoji 19 is smoothly guided indoors through the space 34 and the communication part 28 between the rectifying piece 30 of the upper frame 20 and the shield (shoji) 19. There is. The covering piece 31 covers the communication part 28 of the upper stile 23, and the air that has passed through the communicating part 28 of the upper stile 23 flows into the room through the gap between the upper stile 23 and the covering piece 31. The interval between the rectifying piece 30 and the upper stile 23 is made wider than the interval between the covering piece 31 and the upper stile 23 in order to efficiently guide the air rising along the shield (shoji) 19 to the communication part 28. be. Specifically, the distance between the rectifying piece 30 and the upper stile 23 is approximately 25 mm.
The lower edge of the rectifying piece 30 on the outdoor side of the upper frame 20 and the lower edge of the covering piece 31 on the indoor side are on the same plane as the lower edge of the upper stile 23, and the upper stile 23 is It is hidden by the rectifying piece 30 and the covering piece 31 so that it cannot be seen. The lower edges of the rectifying piece 30 and the covering piece 31 are also on the same plane as the lower edges of the covering piece 15 and the rectifying piece 16 of the upper frame 7 of the outer partition 1.

As shown in FIG. 1, the lower frame 21 is formed in a U-shaped cross section with a groove 35 opening upward, and the lower stile 24 of the shoji 19 is inserted into the groove 35. The upper edge of the lower frame 21 and the upper edge of the lower stile 24 are on the same plane, and the lower stile 24 is hidden from view when viewed from the outdoor side and the indoor side. Note that the upper edge of the lower frame 21 is also on the same plane as the upper edge of the lower frame 8 of the outer partition body 1.

As shown in FIG. 2, the vertical frame 25 is formed into a substantially L-shaped cross section by a main body 36 located on the outer circumferential side of the vertical stile 25 and a protrusion 37 attached to the inner circumferential side of the main body 36. be. The protrusion 37 is provided with an airtight piece 38 that comes into contact with the outdoor side surface of the vertical stile 25.
As shown in FIG. 3(b), in the shoji 19, only the vertical stile 25 among the four circumferential frames is exposed when viewed from the indoor side. A handle 39 for attaching and removing the shoji 19 is provided on the indoor side surface of the vertical stile 25.

As shown in FIG. 1, between the indoor facing surface 40 of the frame 3 of the outer partition 1 and the outdoor facing surface 41 of the frame 18 of the inner partition 2, a heat insulating material 42 is provided around the four sides. be. The heat insulating material 42 is composed of a plastic foam heat insulating material 43 such as styrene foam, and a wooden decorative material 44 provided to cover the inner circumferential side of the foam heat insulating material 43. The inner peripheral side edge 45 of the heat insulating material 42 is flush with the inner peripheral side edge of the frame 3 of the outer partition 1 and the inner peripheral side edge of the frame 18 of the inner partition 2.
In this way, by providing the heat insulating material 42 between the indoor facing surface 40 of the frame 3 of the outer partition 1 and the outdoor facing surface 41 of the frame 18 of the inner partition 2, Since heat transfer between the frame 3 of the partition body 1 and the frame 18 of the inner partition body 2 is blocked by the heat insulating material 42, the heat insulation performance is improved.
Furthermore, in this fitting, the inner peripheral side edges of the frames 3, 18 of the outer partition body 1 and the inner partition body 2 and the inner peripheral side edge 45 of the heat insulating material 42 are made substantially on the same plane, so when viewed from the outdoor side and the indoor side The heat insulating material 42 is not exposed on the inner peripheral side of the frames 3, 18 of the outer partition 1 and the inner partition 2, and the design is good.

As shown in FIGS. 1 and 2, an outdoor wall material 46 is provided on the indoor side of the frame 18 of the inner partition 2. In the indoor wall material 46, an opening 47 is formed so as to be flush with the inner peripheral side edge of the frame 18 of the inner partition 2. Therefore, when viewed from the indoor side, the frame 18 of the inner partition 2 is hidden behind the indoor wall material 46 and cannot be seen.

Next, the construction procedure for this fitting will be explained. First, as shown in FIG. 4(a), a heat insulating material 42 is attached to the opening of the frame. Next, as shown in FIG. 4(b), the outer partition 1 is attached to the opening of the frame from the outdoor side. Next, as shown in FIG. 4(c), the inner partition 2 is attached to the opening of the frame from the indoor side. Finally, as shown in FIG. 4(d), the indoor wall material 46 is attached.

In addition to providing an inner partition 2 using a resin frame 18 and frames 23, 24, 25 and double-glazed glass 26, this fitting has an outdoor ventilation section (communication section) 13 of an outer partition 1. Air flows indoors and outdoors through the indoor ventilation part (communication part) 28 of the inner partition 2, and at that time, the air flows through the intermediate layer 48 between the outer partition 1 and the inner partition 2, and the inner surface of the outer partition 1. By flowing in a detour along the outer surface of the inner partition body 2, heat transfer in the direction opposite to the direction in which air flows is prevented, and an even greater heat insulating effect is exhibited.
In winter, adjust the indoor pressure to negative using a ventilation fan, etc., and make sure that the air flows through the fittings from outside to inside, as shown in Figure 1. (The arrows in the figure indicate the air flow.) ). The cold air (outside air) flowing in from the outdoor ventilation section 13 of the outer partition 1 hits the rectifying piece 16 on the indoor side of the upper frame 7 and flows out downward, and then the cold air flows through the outer partition 1 by cold draft. It flows along the inner surface of the glass 26 to below the intermediate layer 48 and then turns back, where the indoor heat is transmitted from the glass 26 of the inner partition body 2 and is warmed, and rises along the outdoor surface of the glass 26. During this time, the glass 26 The heat that escapes from the room to the outside is recovered by air flow. In addition, when the window receives solar radiation, solar heat can be obtained while the air flows through the intermediate layer 48 along the inner surface of the outer partition 1 and the outer surface of the inner partition 2. . Thereafter, the warmed air flows into the space 34 between the outdoor side rectifying piece 30 of the upper frame 20 and the upper stile 23, passes through the indoor side ventilation section 28 provided in the upper stile 23, and passes through the upper stile 23. It flows into the room through the gap between the indoor side surface of the upper frame 20 and the covering piece 31 on the indoor side of the upper frame 20. Even when air passes through the gap between the indoor side ventilation part 28, the upper stile 23, and the covering piece 31, the heat of the upper stile 23 and the upper frame 20 warmed by indoor heat is recovered by the air flow. By bringing the warmed air into the room, the recovered heat can be returned to the room.

In this way, when air flows from the outdoors into the room in winter, this fitting detours the inside of the intermediate layer 48 along the inner surface of the glass 6 of the outer partition 1 and the outer surface of the glass 26 of the inner partition 2. As the air flows through the building, the heat transferred from indoors to outdoors is recovered by the air flow and returned to the indoor area, which almost eliminates heat loss from indoors to outdoors, resulting in extremely high insulation properties. In addition, since outside air can be warmed and brought into the room, people staying indoors do not feel cold wind, and the heating efficiency is good.
This fitting has the rectifier piece 16 of the upper frame 7 on the indoor side of the outdoor ventilation section 13 of the outer partition body 1, so that it is not necessary to partition the inside of the intermediate layer 48 by providing a rectifier plate, a blind, etc. in the intermediate layer 48. Also, the flow of air exiting from the ventilation portion 13 of the outer partition 1 is directed downward, and the air flow detours along the inner surface of the outer partition 1 and the outer surface of the inner partition 2 into the intermediate layer 48. You can make it.
Furthermore, in this fitting, a space 34 is provided between the outdoor rectifying piece 30 of the upper frame 20 of the inner partition 2 and the outdoor side surface of the upper stile 23, so that the space 34 is provided along the outer surface of the inner partition 2. By flowing the rising air into the space 34, it is prevented from flowing back to the outside of the room and can be guided smoothly into the room.

In the summer, use a ventilation fan to maintain positive pressure in the room so that air flows from the room to the outside, contrary to the situation in the winter. The air coming out of the indoor ventilation part 28 of the inner partition 2 hits the rectifying piece 30 on the outdoor side of the upper frame 20 and flows downward, and since the temperature of the indoor air is lower than the outdoor air, the air flows downward through the glass 26 of the inner partition 2. It flows downward along the outdoor side surface, then turns back at the lower part of the intermediate layer 48, and as the heat of the glass 6 of the outer partition body 1 is transmitted, it rises along the indoor side surface of the glass 6 of the outer partition body 1, and during this time The heat that enters the room from outside through the glass 6 is recovered by air flow. After that, the air enters the space 17 between the rectifier piece 16 on the indoor side of the upper frame 7 and the upper stile 5, passes through the outdoor side ventilation part 13 of the outer partition 1, and passes through the outdoor side ventilation part 13 of the outer partition 1. Air is released outdoors through the gap between the covering piece 15 and the upper frame 5. When the air passes through the outdoor ventilation part 13, the heat coming into the room through the upper stile 5 is recovered by the air flow. Then, by releasing the air outdoors, the heat recovered from the glass 6 and the upper frame 5 of the outer partition 1 is discarded outdoors. In this way, the heat transferred from the outdoors to the indoors is recovered by the air flow and discarded outdoors, which prevents heat transport from the outdoor side to the indoor side, which is the opposite direction to the direction in which the air flows out, resulting in excellent insulation. It works effectively and keeps the room cool.

In this way, when air flows from indoors to outdoors in the summer, this fitting detours the inside of the intermediate layer 48 along the outer surface of the glass 26 of the inner partition 2 and the inner surface of the glass 6 of the outer partition 1. By allowing the air to flow from outside to inside the room, the heat transferred from outside to inside the room is collected and disposed of outside, thereby suppressing the heat coming into the room from outside, thereby reducing the cooling load.
This fitting has the rectifying piece 30 of the upper frame 20 on the outdoor side of the indoor side ventilation part 28 of the inner partition body 2, so that it is not necessary to partition the inside of the intermediate layer 48 by providing a rectifying plate, a blind, etc. in the intermediate layer 48. Also, the flow of air exiting from the ventilation portion 28 of the inner partition 2 is directed downward, and the air flow detours along the outer surface of the inner partition 2 and the inner surface of the outer partition 1 into the intermediate layer 48. You can make it.
Furthermore, in this fitting, a space 17 is provided between the rectifying piece 16 on the indoor side of the upper frame 7 of the outer partition 1 and the indoor side surface of the upper stile 5, so that the space 17 is provided along the inner surface of the outer partition 1. By flowing the rising air into the space 17, it is prevented from flowing back into the room and can be smoothly guided to the outside.

The gap between them is defined as a communication section (indoor ventilation section) 28 through which air communicates between the indoor and outdoor areas. Further, the air that has passed through the communication portion 28 circulates inside and outside the room through the gap between the roll screen 49 and the covering piece 31 on the indoor side. A space 34 is provided between the roll screen 49 and the outdoor rectifying piece 30, and the space 34 is continuous with the communication portion 28.
