As shown in FIG. 1, heat insulating materials 42 are provided on four circumferences between the indoor side finding surface 40 of the frame 3 of the outer partition body 1 and the outdoor side finding surface 41 of the frame 18 of the inner partition body 2. be. The heat insulating material 42 is composed of a plastic-based foamed heat insulating material 43 such as styrofoam and a wooden decorative material 44 provided so as to cover the inner peripheral side thereof. 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 body 1 and the inner peripheral side edge of the frame 18 of the inner partition body 2.
This fitting is provided with a heat insulating material 42 between the indoor side finding surface 40 of the frame 3 of the outer partition body 1 and the outdoor side finding surface 41 of the frame 18 of the inner partition body 2 in this way. Since the 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 insulating performance is improved.
Further, in this fitting, since the inner peripheral side edges of the frames 3 and 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 substantially flush with each other, they are 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 and 18 of the outer partition body 1 and the inner partition body 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 body 2. The interior side wall member 46 is formed with an opening 47 so as to form the same surface as the inner peripheral side edge of the frame 18 of the inner partition body 2. Therefore, when viewed from the indoor side, the frame 18 of the inner partition body 2 is hidden behind the indoor side wall member 46 and cannot be seen.

Next, the construction procedure of this fitting will be described. First, as shown in FIG. 4A, the heat insulating material 42 is attached to the opening of the skeleton. Next, as shown in FIG. 4B, the outer partition body 1 is attached to the skeleton opening from the outdoor side. Next, as shown in FIG. 4C, the inner partition 2 is attached to the skeleton opening from the indoor side. Finally, as shown in FIG. 4D, the interior side wall material 46 is attached.

In this fitting, in addition to providing the inner partition 2 using the resin frame 18, the frames 23, 24, 25 and the double glazing 26, the outer partition 1 and the outdoor ventilation portion (communication portion) 13 are provided. Air flows inside and outside the room through the indoor ventilation portion (communication portion) 28 of the inner partition body 2, and at that time, air flows through the intermediate layer 48 between the outer partition body 1 and the inner partition body 2 on the inner surface of the outer partition body 1. By detouring along the outer surface of the inner partition body 2 and flowing, heat transfer in the direction opposite to the inflow direction of air is hindered, and a further heat insulating effect is exhibited.
Explaining the case of winter, the room is adjusted to a negative pressure by a ventilation fan or the like, and as shown in Fig. 1, the air flows from the outside to the room of this fitting (arrows in the figure indicate the air flow). Shows). The cold air (outside air) that has flowed in from the outdoor ventilation portion 13 of the outer partition 1 hits the rectifying piece 16 on the indoor side of the upper frame 7 and flows downward, and then the cold air flows out downward by the cold draft of the outer partition 1. After flowing to the bottom of the intermediate layer 48 along the inner side surface of the glass 26, the glass 26 is warmed by transferring the heat of the room from the glass 26 of the inner partition body 2, and rises along the outdoor surface of the glass 26 during this period. The heat that escapes from the glass to the outside is recovered by the flow of air. Further, when the window receives solar radiation, the solar heat can be acquired while the air flows through the intermediate layer 48 along the inner side surface of the outer partition body 1 and the outer surface of the inner partition body 2 in this way. .. After that, the warmed air flows into the space 34 between the rectifying piece 30 on the outdoor side of the upper frame 20 and the upper stile 23, passes through the indoor ventilation portion 28 provided in the upper stile 23, and passes through the upper stile 23. It flows into the room through a gap between the indoor side surface of the room and the covering piece 31 on the indoor side of the upper frame 20. Even when the air passes through the gap between the indoor ventilation portion 28, the upper stile 23, and the covering piece 31, the heat of the upper stile 23 and the upper frame 20 warmed by the heat in the room is recovered by the air flow. By taking the warmed air into the room, the recovered heat can be returned to the room.

In this way, when air flows from the outside to the inside of the room in winter, the 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. When the air flows, the heat transferred from the room to the outside is recovered by the flow of air and returned to the room, so that the heat loss from the room to the outside is almost eliminated, so that extremely high heat insulation can be obtained. In addition, since the outside air can be warmed and taken into the room, people in the room do not feel the cold wind, and the heating efficiency is good.
This fitting has the rectifying piece 16 of the upper frame 7 on the indoor side of the outdoor ventilation portion 13 of the outer partition body 1, so that the intermediate layer 48 is not provided with a rectifying plate, a blind, or the like to partition the inside of the intermediate layer 48. Also, the air flow from the ventilation portion 13 of the outer partition body 1 is directed downward, and the air flow diverting into the intermediate layer 48 along the inner side surface of the outer partition body 1 and the outer surface of the inner partition body 2 is allowed to flow downward. Can be made.
Further, 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 surface of the upper stile 23, so that the space 34 is provided along the outer surface of the inner partition 2. By flowing into the same space 34, the raised air can be prevented from flowing back to the outside of the room and can be smoothly guided into the room.

In the summer, the pressure inside the room is adjusted to positive by using a ventilation fan, etc., so that the air flows from the room to the outside, contrary to the winter. The air emitted from the indoor ventilation portion 28 of the inner partition 2 hits the rectifying piece 30 on the outdoor side of the upper frame 20 and flows downward, and the temperature of the indoor air is lower than that of the outdoor, so that the glass 26 of the inner partition 2 It flows downward along the outdoor side surface, then folds back at the lower part of the intermediate layer 48, and rises along the indoor side surface of the glass 6 of the outer partition body 1 by transferring heat from the glass 6 of the outer partition body 1 during this period. The heat that enters the room from the outside through the glass 6 is recovered by the flow of air. After that, the air enters the space 17 between the rectifying piece 16 on the indoor side of the upper frame 7 and the upper stile 5, passes through the outdoor ventilation portion 13 of the outer partition body 1, and is on the outdoor side of the upper frame 7. Air is released to the outside through the gap between the covering piece 15 and the upper stile 5. When the air passes through the outdoor ventilation portion 13, the heat that enters the room through the upper stile 5 is recovered by the air flow. Then, when the air is released to the outside, the heat recovered from the glass 6 and the upper stile 5 of the outer partition 1 is discarded to the outside. By recovering the heat transferred from the outside to the room by the air flow and discarding it outside the room in this way, heat transfer from the outside to the inside, which is the direction opposite to the direction in which the air flows out, is hindered, and excellent heat insulation is achieved. It is effective and keeps the room cool.

In this way, when air flows from the room to the outside in the summer, the 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, the heat transferred from the outside to the room is recovered by the flow of air and discarded outside the room, so that the heat entering the room from the outside can be suppressed, so that the cooling load can be suppressed.
This fitting has a rectifying piece 30 of the upper frame 20 on the outdoor side of the indoor ventilation portion 28 of the inner partition body 2, so that the intermediate layer 48 is not provided with a rectifying plate, a blind, or the like to partition the inside of the intermediate layer 48. Also, the flow of air coming out of the ventilation portion 28 of the inner partition body 2 is directed downward, and the air flow diverting in the intermediate layer 48 along the outer surface of the inner partition body 2 and the inner side surface of the outer partition body 1 is allowed to flow downward. Can be made.
Further, the present fitting is provided with a space 17 between the rectifying piece 16 on the indoor side of the upper frame 7 of the outer partition body 1 and the indoor side surface of the upper stile 5, so that the space 17 is provided along the inner side surface of the outer partition body 1. By flowing the raised air into the same space 17, it is possible to prevent backflow to the indoor side and smoothly guide the air to the outside.

The gap between them is a communication portion (indoor side ventilation portion) 28 through which air communicates indoors and outdoors. Further, the air that has passed through the communication portion 28 circulates indoors and outdoors 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 rectifying piece 30 on the outdoor side, and the space 34 is continuous with the communication portion 28.

Similar to the first embodiment, the fitting of the second embodiment blows air from the outside to the inside or indoors along the inner side surface of the glass 6 of the outer partition body 1 and the outer surface of the roll screen 49 of the inner partition body 2. High heat insulation performance can be obtained by flowing the air from the room to the outside, which has the effect of suppressing the heating and cooling load. By using the roll screen 49 as the shielding body of the inner partition body 2, the cost can be reduced as compared with the case where the double-glazed window is used. In addition, it can block the line of sight from the outside and strong sunlight.
Since the roll screen 49 is installed in the upper frame 20 and the indoor side of the upper frame 20 is covered with the indoor side wall material 46, neither the roll screen 49 nor the upper frame 20 can be seen from the indoor side, and further.
