Along with curtains, blinds are typical solar shading devices.As is well known, blinds are made of slats arranged vertically or horizontally with strings so that the installation angle can be changed. When heated, long-wave radiation is emitted from the surface into the room, which may reduce the solar radiation shielding effect.
これに対して、例えば実開昭49−84935号公報
や実開昭49−31142号公報のように太陽光が入射

けることなどが考えられている。 To deal with this, it has been considered, for example, to provide a member such as aluminum foil to increase the reflectance on the side surface where sunlight enters, as disclosed in Japanese Utility Model Application Publication No. 49-84935 and Japanese Utility Model Application Publication No. 49-31142. There is.

態となり、室内から外が見えないので重苦しい雰
囲気となる。 However, even with this method, it is not possible to prevent a portion of the solar heat from being absorbed into the slats, causing a rise in the temperature of the slats themselves, and as a result, the amount of radiant heat toward the interior of the room increases. In addition, in order to increase the reflectance in this way, it is necessary to block even visible light, and the blinds are completely closed, making it impossible to see outside from inside the room, creating a heavy atmosphere.

A blind is shown in which a solar energy selective absorption film is formed on one side of the slat, and a film that reflects sunlight and infrared rays is formed on the other side.

The above-mentioned Utility Model Application Publication No. 167195/1983 and Japanese Patent Application Publication No. 1983-
The selective absorption film used in Publication No. 167195 absorbs short wavelengths and reflects long wavelengths, and suppresses the heat partially absorbed by the slats from radiating into the room. does not have the property of transmitting visible light, and even if the slat base were made of a transparent material, the provision of this selective absorption film would make it impossible to see the outside from inside the room when it is fully closed.
本考案の目的は前記従来例の不都合を解消し、
スラツトからでる室内への熱放射を抑制して日射
遮蔽効果が増大できるのみならず、室内からのみ
外の景色を眺められて窓は明るさ、眺望という居
住者にとつて重要な居住性能要素を確保できるブ
ラインドを提供することにある。 The purpose of the present invention is to eliminate the disadvantages of the conventional example,
Not only can heat radiation from the slats into the room be suppressed, increasing the solar radiation shielding effect, but windows can also provide brightness and a view, which are important livability performance factors for residents, since the outside scenery can only be seen from inside the room. Our goal is to provide blinds that can be secured.
本考案のブラインドは、前記目的を達成するた

In order to achieve the above-mentioned object, the blind of the present invention is characterized in that the inner surface of the transparent base of the slat is covered with a selective transmission film that has low long-wavelength emissivity and is transparent to visible light.
本考案によれば、スラツトの内側面を覆う長波

According to the present invention, the selective transmission film with low long-wavelength emissivity that covers the inner surface of the slat reduces the amount of heat radiated toward the interior of the room from the heat rays absorbed by the slat, and the base that makes up the slat is transparent. The selective transmission film on the inside is extremely thin and transparent to visible light, so it is difficult to see inside the room from outside due to reflected light, but from inside the room you can freely see the scenery outside.
以下、図面について本考案の実施例を詳細に説
明する。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第１図は本考案のブラインドの実施例を示す横
型ブラインドの縦断側面図で、図中１はブライン
ドのスラツトであり、アクリルその他の合成樹脂
製の透明基盤で形成される。 FIG. 1 is a longitudinal sectional side view of a horizontal blind showing an embodiment of the blind of the present invention. In the figure, 1 is a slat of the blind, which is formed of a transparent base made of acrylic or other synthetic resin.
このスラツト１の内側面、すなわち室内側面を
長波長放射率の小さい選択透過性を有する被膜２
で覆つた。 The inner surface of this slat 1, that is, the indoor surface, is coated with a coating 2 having selective permeability with low long-wavelength emissivity.
I covered it with
該被膜２は、(1)真空蒸着やスパツタリングによ
りMgF2のような屈屈折率の誘電体を反射防止膜
としてコーテイングする方法、(2)ガラスなどの表
面を選択エツチングし、低屈折率の表面層を作る
方法、(3)赤外域で反射率の大きい金属薄膜を誘電
体で挟んで可視域の透過率を上げる方法、(4)可視
域で透明であるに十分なバンドキヤツプ（3eV以
上）をもつ半導体（例えばSnO2，In2O3，
Cd2SnO4など）中の自由キヤリアのプラズマ振動
によるカツトオフを利用する「Drude Mirror」
法などによりスラツト１の表面に施される。 The coating 2 can be obtained by (1) coating a dielectric material with a refractive index such as MgF 2 as an antireflection film by vacuum deposition or sputtering, or (2) selectively etching the surface of glass or the like to form a surface with a low refractive index. (3) A method to increase the transmittance in the visible region by sandwiching a metal thin film with high reflectance in the infrared region between dielectric materials, (4) A bandcap sufficient to be transparent in the visible region (3 eV or more) (e.g. SnO 2 , In 2 O 3 ,
"Drude Mirror" utilizes cut-off caused by plasma vibration of free carriers in Cd 2 SnO 4 , etc.)
It is applied to the surface of the slat 1 by a method or the like.
また、この被膜２は可視光透過性を持たせるた
めこれを極薄に形成した。 Further, this coating 2 was formed extremely thin in order to have visible light transmittance.
次に使用法及び作用について説明すると、被膜
２としてポリエステルフイルムに透明熱線反射層
を蒸着したフイルム（商標名ルミソーラ）を利用
した場合、第２図に示すように可視光線の透過率
が約70％である一方、熱線の反射率は約70％であ
る。 Next, to explain how to use it and how it works, when a film (trade name: Lumisola), which is a polyester film with a transparent heat-reflecting layer deposited on it, is used as coating 2, the transmittance of visible light is about 70%, as shown in Figure 2. On the other hand, the reflectance of heat rays is about 70%.
従つて、ブラインドのスラツト１に入射する日
射の熱線の大部分は膜２によつて外側に反射され
るが、一部はスラツト１に吸収されその温度を上
昇させようとする。その結果、スラツト１の室内
側面から室内に向けて放射熱３が放出されるが、
スラツト１の室内側面を覆つている被覆２は放射
率が小さいので室内側へ向けての放射熱３の放出
が抑制され、こうして夏は太陽の熱線や屋外の熱
気のほとんどが室内へ侵入することはない。 Therefore, most of the heat rays of solar radiation incident on the slats 1 of the blind are reflected outwardly by the membrane 2, but some are absorbed by the slats 1 and tend to increase their temperature. As a result, radiant heat 3 is released from the indoor side of the slat 1 into the room.
The coating 2 that covers the indoor side of the slat 1 has a low emissivity, so it suppresses the release of radiant heat 3 toward the indoor side, and in the summer, most of the sun's heat rays and outdoor hot air enter the room. There isn't.
また、逆に室内の暖気は被膜２で反射され再び
室内に戻されるから、冬は室内の暖房熱が窓から
屋外に流出することがない。 Moreover, since the warm air inside the room is reflected by the coating 2 and returned to the room, the heating heat inside the room does not leak out through the window in winter.
また、選択透過性を有する被膜２は、通常放射
率特性を確保しつつ可視光線を透過できるから、
室内側から室外を見ることができ、視界がさえぎ
られることがない。一方、反射する熱線により外
から室内は非常に見えにくいものとなる。 In addition, since the coating 2 having selective permeability can transmit visible light while ensuring normal emissivity characteristics,
You can see the outdoors from the indoor side without being obstructed. On the other hand, the reflected heat rays make it extremely difficult to see inside the room from the outside.
さらに、被膜２は前記のごとく可視光透過率が
大きいから、スラツト１が着色されていてもその
色を損うことがないものである。 Furthermore, since the coating 2 has a high visible light transmittance as described above, even if the slat 1 is colored, the color will not be lost.
そして、かかるブラインドを窓ガラスの内側に
配設した場合は、ブラインドのスラツト１に一部
吸収された熱は、前記のごとく室内へ向けての放
熱は抑制されるが、外側に向けて放熱されるため
に、ガラスとブラインドとの間の空気の温度が上
昇することとなるので、この部分の空気をフアン
等で室外に排出することが望まれる。 When such a blind is placed inside the window glass, the heat partially absorbed by the slats 1 of the blind is suppressed from being radiated indoors as described above, but is radiated outward. As a result, the temperature of the air between the glass and the blind increases, so it is desirable to exhaust the air in this area to the outside using a fan or the like.
以上述べたように本考案のブラインドは、室内
側への熱放射を抑制して日射遮蔽効果が増大でき
るので、夏は室内が涼しく、しかも室内の暖気を
再び室内側へ反射するから冬は暖かいものであ
る。しかも、室内側からのみ外の景色が眺められ
て窓は明るさ、眺望という居住者にとつて重要な
居住性能要素を確保できる。
As mentioned above, the blinds of the present invention can suppress heat radiation toward the indoor side and increase the solar radiation shielding effect, keeping the room cool in the summer, and warm in the winter because it reflects the warm air indoors back into the room. It is something. Moreover, the outside scenery can be seen only from the inside of the room, and the windows can ensure brightness and views, which are important livability performance factors for residents.
また、スラツトの表裏面に被膜を設けるだけで
すむので容易かつ安価に製作でき、取扱いも簡単
なものである。 Further, since it is only necessary to provide a coating on the front and back surfaces of the slat, it can be manufactured easily and inexpensively, and is easy to handle.
