Description

[Detailed Description of the Invention] The present invention relates to a heat-insulating sash in which a shoji is attached to a window frame.

Conventionally, insulating sashes have a shape in which the frame that makes up the window frame is an outdoor frame and an indoor frame that are connected via a heat insulating material, and each frame that makes up a shoji is connected to an outdoor frame and an indoor frame. It is known to have a shape in which the two are connected via a heat insulating material, thereby blocking heat conduction between the outdoor side and the indoor side.

However, with this structure, a part of the indoor frame is exposed to the outdoor side, so heat is conducted between the outdoor side and the indoor side through this exposed part, reducing the insulation effect. Put it away.

Particularly in cold regions, low-temperature outside air is transmitted to the indoor frame through the exposed portion, cooling the indoor frame, resulting in condensation and water accumulation on the interface between the indoor frame and the frame. The problem is that this water freezes, making the window frame unstable.

This invention was developed in view of the above circumstances, and its purpose is to improve the heat insulation effect by reliably preventing outside air from being transmitted to the indoor frame, and to provide heat insulation with excellent airtightness, watertightness, and sound insulation effects. It is to provide satsushi.

Note that each airtight material is rubber, foam insulation material, etc.

Therefore, the airtightness and watertightness between the window frame A and the inner and outer shoji screens B and C can be improved, and the sound insulation effect between the inside and outside of the room can also be improved.

In addition, the outdoor side of each indoor frame body 1b, 2b, 3b, 3b is covered with an airtight material a and a member 71, an airtight material b and c, and an airtight material d, d', and e, respectively. Since there are no exposed parts, there is no heat conduction between the indoor and outdoor frames, resulting in an excellent insulation effect.Especially in cold regions, outside air is transmitted to the indoor frame and condenses, causing condensation between the indoor frame and the frame. This prevents water from accumulating between the window frame and the window frame, causing the water to freeze and making the window frame unstable.

The present invention is as described above, the outdoor part of the indoor frame of the upper frame 1 is covered with the member 71 and the upper horizontal airtight material a, and the outdoor part of the indoor frame of the lower frame 2 is covered with the lower horizontal airtight material. Since it is covered with material b and airtight material c, and the indoor side member of the vertical stile is covered with a vertical airtight material, outside air will not come into contact with the outdoor side part of the indoor frame of each frame that makes up window frame A. Moreover, since the gap between the upper frame 1 and the upper surface of the outer shoji upper stile is blocked by the member 71 and the resin plate 72, no gap is created between the upper frame 1 and the upper surface of the outer shoji upper stile. This prevents outside air from flowing into the room, and these two factors work together to provide excellent heat insulation. Particularly in cold regions, outside air is transmitted to the indoor frame and condenses, water accumulates between the indoor frame and the frame, and this water can be prevented from freezing and making the window frame unstable.

Further, since the resin plate 72 is provided on the lower surface of the member 71 and the upper surface of the upper stile of the outer shoji C is pressed against the resin plate 72, the upper surface of the upper stile can smoothly slide along the resin plate 72. C can be opened and closed smoothly.

In addition, since the member 71 has elasticity, the resin plate 72
It can be compressed and deformed by pressing, and when attaching the outer shoji C to the window frame, the upper surface of the upper stile can be compressed and deformed by pressing the resin plate 72.
The member 71 can be compressed and deformed by pressing the member 71 against the member 71, so that it can be attached in an easy-to-understand manner.

The abutting piece 54 and the horizontal protruding piece 55 abut on the upper horizontal airtight member a, the abutting piece 57 and the horizontal protruding piece 58 abut on the lower horizontal airtight member b, and the abutting piece 64 and the horizontal protruding piece 58 on the vertical airtight member b.
65 are in contact with each other, so the window frame A and the inner/outer shoji B, C
In addition to improving the airtightness and watertightness between the
It is possible to prevent the outside air temperature transmitted through the outdoor frame from being transmitted as radiant heat to the indoor frame.

The upper frame insulation material 4, the lower frame insulation material 5, and the vertical frame insulation material 6 are each covered and do not come into contact with the outside air, so
It will not deteriorate prematurely.
