Description
本願は、2015年10月9日に、日本に出願された特願2015-201210号に基づき優先権を主張し、その内容をここに援用する。
なお、以下の説明に用いる各図面では、各部材を認識可能な大きさとするため、各部材の縮尺を適宜変更している。
また、以下の説明において、採光装置の位置関係(上下、左右、前後)については、採光装置の使用時における位置関係(上下、左右、前後)に基づくものとし、特に説明がない限りは、図面においても、採光装置の位置関係は、紙面に対する位置関係と一致するものとする。
以下、本発明の第1実施形態として、ブラインドの構成について説明する。
なお、以下の各図面においては、各構成要素を見やすくするため、構成要素によって寸法の縮尺を異ならせて示すことがある。
採光シート10は、図3Aに示すように、長手方向(X方向)に垂直な断面(A-A’)において矩形状を呈する基材41と、基材41の第1面41aに設けられた光透過性を有する複数の採光部42と、複数の採光部42の間に設けられた空隙部43と、を備える。
図5は、各採光スラットにおける採光部の傾斜角度を示す図である。
図1に示した採光領域5は、図5に示すように、採光方向(射出方向)が異なる3種類の採光スラット4A,4B,4Cにより構成され、各採光スラット4A,4B,4Cが鉛直方向(Z方向)にこの順で繰り返し配列されている。
具体的に、採光スラット4Aを構成する採光シート10Aにおける複数の採光部(第3の採光部)42aは、基材(第1の基材)41Aの延在方向に沿う端辺41dに平行してその長手方向(X方向)に延在し、且つ、基材41Aの短手方向(Y方向)に並んで設けられている。つまり、上記端辺41dに対する採光部42aの傾斜角度は0°である。
各スラット2は、縦コード15a,15bと横コード16a,16bとの各間に挿入された状態で配置されている。
図10は、窓ガラス1003に貼り付けるタイプの従来の採光シート101による室内1006への採光状態を示す図であって、天井側から見た図である。図11Aは、従来の採光シートから射出される光の拡散状態(グレア光の発生状態)を示す図であって、室内側から見た図である。図11Bは、図11AのB-B’線に沿う断面図である。
このような従来の採光シート101に入射した光は、複数の採光部104における微細構造によって、これら各採光部104の延在方向に交差する方向、つまり窓ガラス1003の上下方向へ拡散されて室内1006へと射出される。このとき、採光部104の延在方向には殆ど拡散されないため、グレア光は太陽と室内に居る人の目線とを結んだ位置で上下方向に引き伸ばされる。このような採光シート101の特性により、グレア光は1本の縦線となって現れて室内1006に居る人に認識されてしまう。室内1006に居る人の位置によって太陽との位置関係が変わるため、採光シート101上でグレアが現れる場所は変わってくるが常に認識されてしまう。このようなグレア光は、室内1006に居る人にとっては不快なものとなっていた。
図12は、本発明の一態様に係るブラインドが設置された室内への採光状態を示す図であって、天井側から見た図である。図13は、本発明の一態様に係るブラインドから射出される光の拡散状態(グレア光の発生状態)を示す図であって、室内側から見た図である。
ここで、採光スラットの変形例について説明する。
図14A~図14Dは、採光スラットの変形例を示す断面図であって、基材の形状がそれぞれ異なっている。
図14Aに示すように、基材46は、長手方向に垂直な断面において屈曲もしくは湾曲した形状を有する。基材46は、第1面41aに第1の領域41Aaを有する第1部分A1と、第1面41aに第2の領域41Abを有する第2部分A2からなる。基材46は、複数の採光部42が設けられた第1部分A1と、採光部42が設けられていない第2部分A2との境界で、基材46の長手方向に平行な中心線に沿って折り曲げられている。
基材46を構成する第1部分A1と第2部分A2のなす角度θは、第1の領域41Aaに形成される採光部42の形状に応じて適宜設定される。
また、屈曲した基材ではなく、図14Cに示すように一端側が湾曲した基材47を用いてもよい。
図15Aに示す採光スラットのように、スラット本体8の一面8a側に採光シート10を設けるとともに、他面8b側に光拡散部材26を設けた構成としてもよい。光拡散部材26としては、例えば、数百~数μm程度の球状の微粒子を樹脂中に分散させた光拡散層を基材に形成した等方拡散部材が挙げることができる。採光シート10が基材41の端辺41dに対して傾斜した採光部42を有する場合は、採光部42の傾きによって窓の左右方向への光拡散効果が得られるため、等方拡散構造を付与してもよい。あるいは、窓の左右方向へより光を拡散させたい場合には、レンチキュラーレンズ等の異方性光拡散構造を付与してもよい。
なお、図15Bに示すように、光拡散部材26側を窓ガラスに向けて設置してもよい。
次に、本発明の第2実施形態として、ロールスクリーンの構成について説明する。

なお、巻取機構33については、このようなプルコード式に限らず、巻芯34をチェーンで回転させるチェーン式の巻取機構や、巻芯34をモータにより回転させる自動式の巻取機構などであってもよい。
次に、本発明の第3実施形態として、ロールスクリーン(採光装置)について説明する。

本実施形態の採光スクリーン52は、巻芯34に一端側が接続された光透過性を有するスクリーン本体53と、スクリーン本体53の一面53a側に設けられた複数の採光シート(採光部材)10と、を備えて構成されている。スクリーン本体53の一面53aには、種類の異なる採光シート10を配置するための各領域が設定されている。
次に、本発明の第4実施形態として、採光パネルについて説明する。
図21は、第4実施形態の採光パネル(採光装置)の全体構成を示す斜視図である。図22Aは第4実施形態の採光パネル本体の概略構成を示す正面図であり、図22Bは、図22AのC-C’線に沿う断面図である。
フレーム62は、平面視矩形状を呈する枠部材からなり、採光パネル本体61の外周部分が差し込まれる不図示の溝部を有する。フレーム62は、アルミニウム合金、又は樹脂などからなる。
次に、採光スラットの変形例として、図23A及び図23Bに示すような採光スラットの構成について説明する。
図23Aは、ブラインドを構成する変形例の採光スラットの概略構成を示す平面図、図23Bは、図23Aの断面図である。
以下に示す採光スラットに用いられる採光部材の基本構成は、上記第1実施形態と略同様である。よって、以下の説明では、異なる個所について詳しく説明し、共通な箇所の説明は省略する。また、説明に用いる各図面において、図1~図8と共通の構成要素には同一の符号を付すものとする。
本実施形態では、3種類の採光シート10A,10B,10Cが一つのスラット本体8上にそれぞれ1枚ずつタイリングされている。
次に、本発明の一態様の採光装置の変形例として、図24A及び図24Bに示すような採光パネルの構成について説明する。
図24Aは、採光パネルの概略構成を示す平面図であって、図24Bは、図24AのE-E’線に沿う断面図である。図25は、比較例として、上下方向に長さを有する採光部材を複数タイリングした際の平面図である。
よって、以下の説明では、異なる個所について詳しく説明し、共通な箇所の説明は省略する。また、説明に用いる各図面において、図21~図22Bと共通の構成要素には同一の符号を付すものとする。
次に、本発明の第5実施形態の採光装置について説明する。
図26Aは、第5実施形態の採光装置の概略構成を示す正面図であり、図26Bは、第5実施形態の採光装置を室内の窓に設置した場合の採光イメージ図である。
図27に示す採光装置のように、採光部42の傾斜角度が互いに異なる複数種類の採光シート10Bを備えていてもよい。ここでは、4種類の採光シート10B(1)、10B(2)、10B(3)、10B(4)を備えた例を挙げている。
採光シート10B(1)は、複数の採光部42が採光シートの延在方向に対して第1の角度θ1=+10°で傾斜している。
採光シート10B(2)は、複数の採光部42が採光シートの延在方向に対して第1の角度θ1=+20°で傾斜している。
採光シート10B(3)は、複数の採光部42が採光シートの延在方向に対して第1の角度θ1=+5°で傾斜している。
採光シート10B(4)は、複数の採光部42が採光シートの延在方向に対して第1の角度θ1=+10°で傾斜している。
一方、図28Aに示すように、採光シート10Aだけで構成された採光装置90の場合は、各採光シート10Aの各採光部42の傾きが採光シート10Aの端辺に対して平行(傾斜角度θが0°)であるため、入射光に対して射出光がほぼ直線的に射出されることになる。
さらに、西側から入射した光LB3は、各採光シート10Aを透過して室内奥の壁部(東)側へ射出される。
例えば、採光装置を設置する窓の向きに応じて、組み合わせる採光シートの種類を変更してもよい。例えば、採光シート10Aと採光シート10Cとによって採光装置を構成してもよいし、採光シート10Bと採光シート10Cとによって採光装置を構成してもよい。
本実施形態では、西向きの窓に設置される採光装置について述べたが、採光シートの組み合せによって、各方位の窓に適した採光装置を構成することが可能である。
図29A、図29Bに示すように、一例として、採光シート10Aと採光シート10Cを用いることで、東向きの窓に適した採光装置80を構成することができる。この場合、上下方向に採光シート10A,10Cを交互に繰り返し配置する。
また、複数種類の採光シートの配列順は、角度順に配列してもよいし、ランダムな配列であってもよい。
次に、採光シートの製造方法について述べる。
図30A,図30Bは、採光シート10Aの製造方法を説明するための図である。
図31A,図31B,図31Cは、採光シート10B,10Cの製造方法を説明するための図である。
L=(R-Bcos(-θ))/Sin(-θ) …(2)
ここでは、原反ロール141のロール幅Wを300mmとしたとき、原反ロール141から斜めに切り出すことのできる採光シート10Bの大きさと、採光部42の傾斜角度と、の関係について述べる。
採光形状の傾斜角度によって、採光シート10Bの長手方向長さを変える方が好ましい。採光部の角度が大きい場合は、採光シート10Bの長手方向長さLを短くし、採光部の角度が小さい場合は、採光シート10Bの長手方向長さLを長くする。
採光部の傾斜角度が異なる採光シートを複数種類用意し、これらを貼り合わせると各採光シートの継ぎ目がばらばらになるため、境界部分が目立ちにくい。
つまり、先の実施形態では、第1の角度θ1(+10°)で傾斜する採光部42bを有する基材41B、第2の角度θ2(-10°)で傾斜する採光部42cを有する基材41C、をそれぞれ1種類ずつ備えた構成としたが、例えばθ1が、+5°、+10°、+15°、+20°とされた採光部をそれぞれ有する複数種類の基材を備えた構成としてもよい。あるいは、角度θ1が+20°、+10°、角度θ2が-10°、-20°とされた採光部をそれぞれ有する複数種類の基材を備えた構成としてもよい。さらに、いずれの構成においても、端辺41dに平行する採光部42aを有する基材41Aを含んだ構成としてもよい。
また、複数種類の基材の配列順に関しても特に限定はなく、採光部の角度順に配列してもよいし、角度に関係なくランダムな配列としてもよい。
図33は、採光装置および照明調光システムを備えた部屋モデル2000であって、図34のJ-J’線に沿う断面図である。図34は、部屋モデル2000の天井を示す平面図である。
より具体的には、50個の室内照明装置2007が10行(Y方向)×5列(X方向)に配列されている。
