The first and second sheet materials are substantially crossed so that light can pass between the blades.
　第１のシート材料と第２のシート材料との間での垂直方向の相対的移動により、翼板の傾斜が変化し、翼板が光を遮る前記第１の位置と、翼板によって光を遮らない前記第２の位置とに、翼板を移動させることができる。 Due to the vertical relative movement between the first sheet material and the second sheet material, the inclination of the blade changes, the first position where the blade blocks light, and The blades can be moved to the second position where they are not blocked.

　しかしながら、前記従来のブラインドでは、前記第１の位置において、翼板が半透明の第１及び第２のシートを通して透視されることになるが、前面側から見ても後面側から見ても、その意匠及び／または機能は同じであり、前面側と後面側とで異ならせることができず、意匠性及び／または機能性の乏しい単調なブラインドとなってしまう。 However, in the conventional blind, in the first position, the blades are seen through the translucent first and second sheets, but when viewed from the front side and the rear side, The design and / or function is the same and cannot be made different between the front side and the rear side, resulting in a monotonous blind with poor design and / or functionality.
　例えば、翼板として暗い色の材質を選択すると、翼板を閉じたときに室内側及び室外側において第１及び第２のシートを通して暗い色の翼板が露出し、光を十分に遮蔽することができブラインドの遮蔽性を高めることができる。その一方で、室外側において暗い色は太陽からの日射を吸収してしまうので、夏季の冷房効果を低減させてしまうという問題がある。 For example, when a dark-colored material is selected as the blade, the dark-colored blade is exposed through the first and second sheets on the indoor side and the outdoor side when the blade is closed, and the light is sufficiently shielded. Can improve the shielding performance of the blinds. On the other hand, since the dark color on the outdoor side absorbs solar radiation, there is a problem of reducing the cooling effect in summer.
　本発明はかかる課題に鑑みなされたもので、その目的は、ルーバを閉じたときに、ブラインドの前面側と後面側とで意匠性及び／または機能性を異ならしめて、意匠性及び／または機能性を高めることができるブラインドを提供することである。 The present invention has been made in view of such problems, and its purpose is to make the design and / or functionality different between the front side and the rear side of the blind when the louver is closed. It is to provide a blind that can be enhanced.

　ルーバが第１方向に対して略直交する状態における前後方向においてルーバは互いに異なる第１部分と第２部分とを有し、ルーバが第１方向に対して略平行状態になったとき、前面側の透光性部材と後面側の透光性部材を通して見えるルーバの第１部分と第２部分の露出程度が異なるようになっている。 In order to achieve the aforementioned object, the blind of the present invention is

　以下、図面を用いて本発明の実施の形態を説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
（第１実施形態）
　図１ないし図５は、本発明の第１実施形態に係るブラインドを示す。 (First embodiment)
1 to 5 show a blind according to a first embodiment of the present invention.
　窓枠や壁２２等にブラケット１１を介して固定されるセットフレーム１０の両端にサイドプレート１２が設けられており、サイドプレート１２には巻取パイプ１４の両端が軸支されて、巻取パイプ１４がサイドプレート１２に対して回転可能となっている。 Side plates 12 are provided at both ends of a set frame 10 fixed to a window frame, a wall 22 or the like via a bracket 11, and both ends of a winding pipe 14 are pivotally supported on the side plate 12. 14 is rotatable with respect to the side plate 12.
　巻取パイプ１４には、２枚の透光性部材である透光性シート１８ａ及び１８ｂの上端が円周方向に間隔を空けた位置にそれぞれ接続されており、各シート１８ａ及び１８ｂは、巻取パイプ１４から互いに前後方向に間隔を空けて垂下される。各シート１８ａ及び１８ｂは、半透明または透明シートで構成され、全く同じ構成のシートであってもよく、または異なる構成のシートであってもよい。従って、各シート１８ａ及び１８ｂは、その光透過率が異なるものであってもよいが、少なくとも以下で説明するルーバ２０を透視することができる程度の光透過率を有している。 The upper ends of the two translucent members 18a and 18b that are translucent members are connected to the winding pipe 14 at positions spaced apart in the circumferential direction, and the respective sheets 18a and 18b are wound around the winding pipe 14, respectively. It hangs down from the take-up pipe 14 at intervals in the front-rear direction. Each of the sheets 18a and 18b is composed of a translucent or transparent sheet, and may be a sheet having the same configuration or a sheet having a different configuration. Accordingly, the sheets 18a and 18b may have different light transmittances, but have at least a light transmittance that allows the louver 20 described below to be seen through.
　前後のシート１８ａ及び１８ｂ間には、図３（ａ）及び図４に示すように、複数のルーバ２０がシート１８ａ及び１８ｂの上下方向（第１方向）に沿って間隔を空けて整列状態に配置されており、各ルーバ２０の前後端部はそれぞれが前後のシート１８ａ及び１８ｂに接続されている。 As shown in FIGS. 3A and 4, a plurality of louvers 20 are aligned between the front and rear sheets 18 a and 18 b at intervals along the vertical direction (first direction) of the sheets 18 a and 18 b. The front and rear ends of each louver 20 are connected to the front and rear seats 18a and 18b, respectively.
　前後のシート１８ａ及び１８ｂ間の距離が変化することで、ルーバ２０はその傾斜角度を変化させることができる。そして、各ルーバ２０は、図３（ａ）及び図４に示すように、前後のシート１８ａ及び１８ｂが離間しているときには、これらに対して略直交する状態となり、よって、隣り合うルーバ２０間が開放された状態となる。一方、図３（ｂ）に示すように、前後のシート１８ａ及び１８ｂが接近しているときには、各ルーバ２０は前後のシート１８ａ及び１８ｂに対して略平行状態となり、隣り合うルーバ同士が部分的に重なり合って、隣り合うルーバ２０の間が閉塞された状態となる。 By changing the distance between the front and rear seats 18a and 18b, the louver 20 can change its inclination angle. As shown in FIGS. 3A and 4, each louver 20 is in a state of being substantially orthogonal to the front and rear seats 18 a and 18 b, and therefore, between adjacent louvers 20. Will be open. On the other hand, as shown in FIG. 3B, when the front and rear sheets 18a and 18b are approaching each other, the louvers 20 are substantially parallel to the front and rear sheets 18a and 18b, and adjacent louvers are partially separated from each other. And the adjacent louvers 20 are closed.
　各ルーバ２０は、合成樹脂繊維または天然繊維からなる織布、編布、不織布、紙シート、合成樹脂シート、木材シートといった任意の材質からなるシートであり、好ましくは可撓性を有する。さらに、各ルーバ２０は、前後のシート１８ａ及び１８ｂに対して略直交する状態における前後方向において互いに異なる第１部分２０ａと第２部分２０ｂとを有している。 Each louver 20 is a sheet made of any material such as a woven fabric, a knitted fabric, a nonwoven fabric, a paper sheet, a synthetic resin sheet, or a wood sheet made of synthetic resin fibers or natural fibers, and preferably has flexibility. Furthermore, each louver 20 has a first portion 20a and a second portion 20b that are different from each other in the front-rear direction in a state substantially orthogonal to the front and rear seats 18a and 18b.
　ここで、第１部分２０ａと第２部分２０ｂが異なるとは、色、模様、材質、光透過率、光反射率または光吸収率等の性質が異なるために、意匠性または機能性が異なったことを意味する。例えば、繊維の種類（色、太さ、材質）またはその織り方、編み方を変えたり、または別の種類の布またはシートを任意の接合手段で接合したりすることで、ルーバ２０を部分的に異なるようにすることができる。１つの例では、第１部分２０ａが意匠性のある意匠柄面を構成するとともに第２部分２０ｂが第１部分２０ａよりも光反射率が高く光吸収率が低い日射反射面（白色の面）を構成することができる。 Here, the first portion 20a and the second portion 20b are different from each other in design, or functionality, because the properties such as color, pattern, material, light transmittance, light reflectance, or light absorption rate are different. Means that. For example, by changing the fiber type (color, thickness, material) or its weaving or knitting method, or by joining another type of cloth or sheet with any joining means, the louver 20 is partially Can be different. In one example, the first portion 20a constitutes a design pattern surface having a design property, and the second portion 20b has a light reflectance higher than that of the first portion 20a and has a lower light absorption rate (white surface). Can be configured.
　好ましくは、第１部分２０ａと第２部分２０ｂは、図３（ａ）に示すように緩やかな横向きのＳ字断面形状をなしているとよく、第１部分２０ａは上向きに凸となっており、第２部分２０ｂは下向きに凸となっている。 Preferably, the first portion 20a and the second portion 20b have a gentle lateral S-shaped cross section as shown in FIG. 3A, and the first portion 20a is convex upward. The second portion 20b is convex downward.
　巻取パイプ１４の一端には図示していないプーリが設けられており、プーリはこれに巻き掛けられる操作チェーン１６によって回転駆動され、この回転を巻取パイプ１４に伝達可能となっている。また、巻取パイプ１４内には、巻取パイプ１４の回転を停止させる状態と回転を許容する状態とに切り換えるストッパが設けられる。ストッパはロールスクリーンにおいて公知の任意のストッパで構成することができる。これらの巻取パイプ１４、操作チェーン１６、プーリ、ストッパによって透光性シート１８ａ、１８ｂを駆動する透光性部材駆動部が構成される。 A pulley (not shown) is provided at one end of the winding pipe 14, and the pulley is rotationally driven by an operation chain 16 wound around the pulley, and this rotation can be transmitted to the winding pipe 14. Further, a stopper that switches between a state in which the rotation of the winding pipe 14 is stopped and a state in which the rotation is allowed is provided in the winding pipe 14. The stopper can be composed of any known stopper in the roll screen. The winding pipe 14, the operation chain 16, the pulley, and the stopper constitute a translucent member driving unit that drives the translucent sheets 18 a and 18 b.
　セットフレーム１０には、巻取パイプ１４の前面に位置し、巻取パイプ１４を覆うカバー部２１が形成されている。 The set frame 10 is formed with a cover portion 21 that is positioned in front of the winding pipe 14 and covers the winding pipe 14.
　ブラインドを窓辺に設定する場合には、原則的には、前面側は室内側となり、後面側は室外側となる。 When setting blinds on windowsills, in principle, the front side is the indoor side and the rear side is the outdoor side.
　次に、第１実施形態に係るブラインドの動作について説明する。 Next, the operation of the blind according to the first embodiment will be described.
　図１及び図４に示すように、２枚の透光性シート１８ａ、１８ｂが離間して各ルーバ２０が前後の透光性シート１８ａ及び１８ｂに対して略直交する状態にあるときには、隣り合うルーバ２０間が開放されている。図５（ａ）に示すように、ブラインドが窓辺に設定されている場合、太陽２６からの日射２８が図５（ａ）中矢印で示すように、窓２４から室内に差し込み、窓２４から差し込んだ日射２８は、後面側の透光性シート１８ｂを通過した後、ルーバ２０に当たり、第２部分２０ｂで反射して斜め上方に向って前面側のシート１８ａを通過して室内に差し込む。 As shown in FIGS. 1 and 4, when the two translucent sheets 18a and 18b are separated from each other and the louvers 20 are substantially perpendicular to the front and rear translucent sheets 18a and 18b, they are adjacent to each other. The louver 20 is open. As shown in FIG. 5A, when the blind is set on the window side, the solar radiation 28 from the sun 26 is inserted into the room from the window 24 as shown by the arrow in FIG. The solar radiation 28 passes through the translucent sheet 18b on the rear surface side, hits the louver 20, is reflected by the second portion 20b, passes obliquely upward, passes through the front sheet 18a, and is inserted into the room.
　朝夕や冬季など太陽高度が低い場合には、ルーバ２０に当たった日射は、第２部分２０ｂで反射されるのみならず、更に第１部分２０ａにおいて吸収される。 When the solar altitude is low, such as in the morning or evening, the solar radiation hitting the louver 20 is not only reflected by the second portion 20b but also absorbed by the first portion 20a.
　また、前後の透光性シート１８ａ及び１８ｂの織り密度を大きくするなどして光透過率を低くすれば、シート１８ａ及び１８ｂ間に中空層ができるため、断熱効果を期待することができる。 In addition, if the light transmittance is lowered by increasing the weaving density of the front and rear translucent sheets 18a and 18b, a hollow layer is formed between the sheets 18a and 18b, so that a heat insulating effect can be expected.
　次に、開放されているルーバ２０間を閉塞するには、操作チェーン１６の室内側を引き下ろす操作をし、巻取パイプ１４を図１中反時計方向に回転させる。すると、図２に示すように、後面側の透光性シート１８ｂが巻取パイプ１４に巻き取られて上昇し、前面側の透光性シート１８ａの上端部が、巻取パイプ１４の室外側の位置に移動する。これにより、２枚の透光性シート１８ａ、１８ｂが接近して、ルーバ２０の傾斜が変化し、第１部分２０ａが第２部分２０ｂに対して相対的に下方に変位する（図３（ｂ））。このとき、第１部分２０ａが上向きに凸となっており、第２部分２０ｂが下向きに凸となっているために、第１部分２０ａが前面側の透光性シート１８ａから該シート１８ａに沿って相対的に下側から平行に倣い、第２部分２０ｂが後面側の透光性シート１８ｂから該シート１８ｂに沿って相対的に上側から平行に倣うことができる。図２及び図５（ｂ）に示すように、ルーバ２０が前後の透光性シート１８ａ及び１８ｂに対して略平行な状態になると、互いに隣り合う上下のルーバ２０の一部同士が重なり合い、ルーバ２０間が閉塞される。 Next, in order to close the open louvers 20, the operation chain 16 is pulled down and the winding pipe 14 is rotated counterclockwise in FIG. Then, as shown in FIG. 2, the rear translucent sheet 18 b is wound around the take-up pipe 14 and rises, and the upper end portion of the front translucent sheet 18 a is outside the take-up pipe 14. Move to the position. Thereby, the two translucent sheets 18a and 18b approach each other, the inclination of the louver 20 changes, and the first portion 20a is displaced downward relative to the second portion 20b (FIG. 3B). )). At this time, since the first portion 20a is convex upward and the second portion 20b is convex downward, the first portion 20a extends from the translucent sheet 18a on the front side along the sheet 18a. Thus, the second portion 20b can follow the parallel from the upper side along the sheet 18b from the light transmitting sheet 18b on the rear surface side. As shown in FIGS. 2 and 5B, when the louver 20 is in a substantially parallel state with respect to the front and rear translucent sheets 18a and 18b, a part of the upper and lower louvers 20 adjacent to each other overlap each other. Between 20 is closed.
　ルーバ２０間が閉塞された状態では、前面側の透光性シート１８ａと後面側の透光性シート１８ｂを通して透視されるルーバ２０の第１部分２０ａと第２部分２０ｂの露出程度が異なるようになっている。 When the space between the louvers 20 is closed, the degree of exposure of the first portion 20a and the second portion 20b of the louver 20 seen through the translucent sheet 18a on the front side and the translucent sheet 18b on the rear side is different. It has become.
　即ち、図３に良く示したように、室外側である後面側から見ると、後面側の透光性シート１８ｂを通して日射反射面である第２部分２０ｂがブラインド後面全体に露出され、窓２４に日射反射面が対面することになる。このため、太陽２６からの日射２８が、図５（ｂ）中矢印で示すように、窓２４から差し込んでも、日射反射面である第２部分２０ｂで反射され、再び窓２４を通過して室外に出ていくことができる。例えば、日射反射面が白色であるとすると、窓２４から差し込んできた日射の６５％程度を反射させることができる。 That is, as shown well in FIG. 3, when viewed from the rear side that is the outdoor side, the second portion 20 b that is the solar reflective surface is exposed to the entire rear surface of the blind through the translucent sheet 18 b on the rear side. The solar reflective surfaces will face each other. For this reason, even if solar radiation 28 from the sun 26 is inserted through the window 24 as indicated by an arrow in FIG. 5B, it is reflected by the second portion 20b, which is the solar reflective surface, and again passes through the window 24 and goes outdoor. Can go out. For example, when the solar radiation reflecting surface is white, about 65% of the solar radiation inserted through the window 24 can be reflected.
　このように、第２部分２０ｂの日射反射効率が高いため、太陽２６からの日射２８をルーバ２０の窓２４と対面する第２部分２０ｂで効率よく反射させることができ、夏季の冷房効率を高めることができる。 Thus, since the solar radiation efficiency of the 2nd part 20b is high, the solar radiation 28 from the sun 26 can be efficiently reflected in the 2nd part 20b which faces the window 24 of the louver 20, and the cooling efficiency in summer is improved. be able to.
　また、室内側である前面側から見ると、前面側の透光性シート１８ａを通じて意匠面である第１部分２０ａがブラインド前面全体に露出されることになるので、室内側から見たブラインドの意匠を快適なものとすることができる。 Further, when viewed from the front side which is the indoor side, the first portion 20a which is the design surface is exposed to the entire blind front surface through the translucent sheet 18a on the front side, so the design of the blind viewed from the indoor side Can be made comfortable.
　こうして、室内側と室内側とで意匠性及び機能性を異ならせることで、ブラインドの意匠性と機能性を高めることができる。 Thus, the designability and functionality of the blind can be enhanced by making the designability and functionality different between the indoor side and the indoor side.
　さらに操作チェーン１６の室内側を引き下ろす操作をし、巻取パイプ１４を図１中反時計方向に回転させると、巻取パイプ１４がシート１８ａ、１８ｂをルーバ２０と共に巻き取っていくので、ブラインドが設定された窓２４を完全に開放することができる。 When the operation pipe 16 is further pulled down and the winding pipe 14 is rotated counterclockwise in FIG. 1, the winding pipe 14 winds the sheets 18a and 18b together with the louver 20, so that the blind Can be completely opened.
　次に、図６Ａ～Ｃに基づいて、各ルーバ２０の第１部分２０ａの前後方向の幅と第２部分２０ｂの前後方向の幅と各ルーバ２０間のピッチに応じて、互いに隣り合うルーバ２０が部分的に重なり合ってルーバ２０間が閉塞されたときのルーバ２０を室内側（前面側）から見た第１部分２０ａと第２部分２０ｂの露出程度と、室外側（後面側）から見た第１部分２０ａと第２部分２０ｂの露出程度とがどのように変化するかを説明する。 Next, based on FIGS. 6A to 6C, the louvers 20 adjacent to each other according to the width in the front-rear direction of the first portion 20a of each louver 20, the width in the front-rear direction of the second portion 20b, and the pitch between the louvers 20. When the louvers 20 are partially overlapped and the space between the louvers 20 is blocked, the first and second portions 20a and 20b are exposed from the indoor side (front side), and viewed from the outdoor side (rear side). How the exposure level of the first portion 20a and the second portion 20b changes will be described.

　（１）～（４）に示すように、互いに隣り合う上のルーバ２０の第１部分２０ａの下端が、下のルーバの第１部分２０ａと第２部分２０ｂの境界と同じ位置かまたはそれよりも下方に位置し、且つ互いに隣り合う上のルーバ２０の第１部分２０ａと第２部分２０ｂの境界が、下のルーバの第２部分２０ｂの上端と同じ位置かまたはそれよりも下方に位置するので、室内側から見ると第１部分２０ａが全面に露出し、室外側から見ると第２部分２０ｂが全面に露出した状態となる。尚、（１）は、図３に示した場合に相当する。 As shown in (1) to (4), the lower end of the first portion 20a of the upper louver 20 adjacent to each other is at the same position as or the boundary between the first portion 20a and the second portion 20b of the lower louver. And the boundary between the first portion 20a and the second portion 20b of the upper louver 20 adjacent to each other is located at the same position as or lower than the upper end of the second portion 20b of the lower louver. Therefore, when viewed from the indoor side, the first portion 20a is exposed to the entire surface, and when viewed from the outdoor side, the second portion 20b is exposed to the entire surface. Incidentally, (1) corresponds to the case shown in FIG.
　図６Ｂは、ｍｉｎ（ａ，ｂ）＜ｙ≦ｍａｘ（ａ，ｂ）を満足する場合を示す。ここで、ｍａｘ（ａ，ｂ）は、ａとｂのうち小さくない方を表す。 FIG. 6B shows a case where min (a, b) <y ≦ max (a, b) is satisfied. Here, max (a, b) represents the smaller of a and b.
　（１）においては、互いに隣り合う上のルーバ２０の第１部分２０ａの下端が、下のルーバの第１部分２０ａと第２部分２０ｂの境界よりも上方に位置し、且つ互いに隣り合う上のルーバ２０の第１部分２０ａと第２部分２０ｂの境界が、下のルーバの第２部分２０ｂの上端と同じ位置かまたはそれよりも下方に位置するので、室内側からは第１部分２０ａと第２部分２０ｂが交互に露出し、室外側からは第２部分２０ｂが全面に露出した状態となる。 In (1), the lower ends of the first portions 20a of the upper louvers 20 adjacent to each other are located above the boundary between the first portions 20a and the second portions 20b of the lower louvers and are adjacent to each other. Since the boundary between the first portion 20a and the second portion 20b of the louver 20 is located at the same position as or lower than the upper end of the second portion 20b of the lower louver, the first portion 20a and the second portion 20b are located from the indoor side. The two portions 20b are alternately exposed, and the second portion 20b is exposed to the entire surface from the outdoor side.
　（２）においては、互いに隣り合う上のルーバ２０の第１部分２０ａの下端が、下のルーバの第１部分２０ａと第２部分２０ｂの境界と同じ位置かまたはそれよりも下方に位置し、且つ互いに隣り合う上のルーバ２０の第１部分２０ａと第２部分２０ｂの境界が、下のルーバの第２部分２０ｂの上端と同じ位置かまたはそれよりも上方に位置するので、室内側から見ると第１部分２０ａが全面に露出し、室外側から見ると第１部分２０ａと第２部分２０ｂとが交互に露出した状態となる。 In (2), the lower end of the first portion 20a of the upper louver 20 adjacent to each other is located at the same position as or lower than the boundary between the first portion 20a and the second portion 20b of the lower louver, Since the boundary between the first portion 20a and the second portion 20b of the upper louver 20 adjacent to each other is located at the same position as or above the upper end of the second portion 20b of the lower louver, it is viewed from the indoor side. The first portion 20a is exposed on the entire surface, and when viewed from the outdoor side, the first portion 20a and the second portion 20b are alternately exposed.
　図６Ｃは、ｙ＞ｍａｘ（ａ，ｂ）を満足する場合を示す。 FIG. 6C shows a case where y> max (a, b) is satisfied.
　（１）～（３）に示すように、互いに隣り合う上のルーバ２０の第１部分２０ａの下端が、下のルーバの第１部分２０ａと第２部分２０ｂの境界よりも上方に位置し、且つ互いに隣り合う上のルーバ２０の第１部分２０ａと第２部分２０ｂの境界が、下のルーバの第２部分２０ｂの上端よりも上方に位置するので、室内側から見ると第１部分２０ａと第２部分２０ｂが交互に露出し、室外側から見ると第１部分２０ａと第２部分２０ｂとが交互に露出した状態となる。第１部分２０ａと第２部分２０ｂの比率は、ａとｂとの比率に応じて、室内側と室外側とで異なるものとなる。 As shown in (1) to (3), the lower end of the first portion 20a of the upper louver 20 adjacent to each other is positioned above the boundary between the first portion 20a and the second portion 20b of the lower louver, In addition, since the boundary between the first portion 20a and the second portion 20b of the upper louver 20 adjacent to each other is located above the upper end of the second portion 20b of the lower louver, when viewed from the indoor side, the first portion 20a The second portions 20b are alternately exposed, and when viewed from the outdoor side, the first portions 20a and the second portions 20b are alternately exposed. The ratio of the first portion 20a and the second portion 20b differs between the indoor side and the outdoor side according to the ratio of a and b.
　以上の図６Ａ～Ｃから、前面側において第１部分２０ａがブラインド全体に露出され、後面側において第２部分２０ｂがブラインド全体に露出されるようにするためには、ルーバ２０同士のピッチ即ち間隔を、第１部分２０ａと第２部分２０ｂの幅の大きくない方の幅以下とすればよいことが分かる。この条件の範囲で、ルーバ２０同士のピッチ即ち間隔を最も大きくするには、第１部分２０ａの幅と第２部分２０ｂの幅を同じ、即ちルーバの幅の１／２とし、ピッチをルーバ２０の幅の１／２にすればよいことが分かる。 6A to 6C, in order to expose the first portion 20a to the entire blind on the front side and to expose the second portion 20b to the entire blind on the rear side, the pitch between the louvers 20 is defined. It can be seen that the width of the first portion 20a and the second portion 20b may be equal to or smaller than the width of the smaller portion. In order to maximize the pitch, that is, the interval between the louvers 20 within this condition, the width of the first portion 20a and the width of the second portion 20b are the same, that is, ½ of the width of the louver, and the pitch is set to the louver 20. It can be seen that it should be ½ of the width.
　また、少なくとも前面側において、第１部分２０ａがブラインド全体に露出されるようにするためには、ルーバ２０同士のピッチ即ち間隔を、第１部分２０ａの幅以下にすればよい。同様に、少なくとも後面側において、第２部分２０ｂがブラインド全体に露出されるようにするためには、ルーバ２０同士のピッチ即ち間隔を、第２部分２０ｂの幅以下にすればよい、ことが分かる。 Also, at least on the front side, in order to expose the first portion 20a to the entire blind, the pitch between the louvers 20, that is, the interval may be set to be equal to or smaller than the width of the first portion 20a. Similarly, at least on the rear surface side, in order to expose the second portion 20b to the entire blind, it can be seen that the pitch between the louvers 20, that is, the interval, should be less than or equal to the width of the second portion 20b. .
　このように、各ルーバ２０の第１部分２０ａの前後方向の幅ａと第２部分２０ｂの前後方向の幅ｂとルーバ２０間のピッチｙに応じて、前面側（室内側）と後面側（室外側）とで意匠性または機能性を異ならせることができる。 Thus, according to the front-rear width a of the first portion 20a of each louver 20, the front-rear width b of the second portion 20b, and the pitch y between the louvers 20, the front side (inner side) and the rear side ( Designability or functionality can be different between the outdoor side).
