Description
本発明は、傾斜が可変となったルーバを有するブラインドに関する。
The present invention relates to a blind having a louver with a variable inclination.
従来、この種のブラインドとしては、日本国特許第2610368号公報に記載されたものが知られている。該公報に記載されたブラインドは、半透明な材料よりなる第1のシート材料と、半透明な材料よりなる第2のシート材料とを平行に配置し、第1のシート材料および第2のシート材料に複数の不透明な帯状材料の両縁部部分を接着して窓遮蔽体を構成しており、帯状材料の中央部分が翼板、即ちルーバを形成し、該翼板は窓遮蔽体を閉じた第1の位置で実質的に平面状をなして第1および第2のシート材料にほぼ平行に延びて光の透過を少なくとも部分的に阻止するとともに、窓遮蔽体の開いた第2の位置で第1および第2のシート材料にほぼ交差して延びて翼板間を光が透過し得るように構成している。
Conventionally, a blind described in Japanese Patent No. 2610368 is known as this type of blind. In the blind described in the publication, a first sheet material made of a translucent material and a second sheet material made of a translucent material are arranged in parallel, and the first sheet material and the second sheet are arranged in parallel. A window shield is formed by adhering both edge portions of a plurality of opaque belt-like materials to the material, and the central portion of the belt-like material forms a blade, that is, a louver, and the blade closes the window shield. A second position in which the window shield is open while at least partially blocking light transmission by extending substantially parallel to the first and second sheet materials in a substantially planar manner at the first position. 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.

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.

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.
図6A~Cにおいて、各ルーバ20の第1部分20aの前後方向の幅をa、第2部分20bの前後方向の幅をb、各ルーバ20の前後方向の幅をx、各ルーバ20間のピッチyとおき、第1部分20aが第2部分20bよりも下方に変位しているものとする。尚、図6では、理解を容易にするために隣り合うルーバ20を左右にずらして表わしており、図6の点線で囲まれた部分が実際に見えるブラインドの一般部分(上端及び下端を除いた部分の一部を言う)を表している。
6A to 6C, the front-rear width of the first portion 20a of each louver 20 is a, the front-rear width of the second portion 20b is b, the front-rear width of each louver 20 is x, and the distance between the louvers 20. It is assumed that the first portion 20a is displaced below the second portion 20b with the pitch y. In FIG. 6, the adjacent louvers 20 are shifted to the left and right for easy understanding, and the general portion of the blind (excluding the upper and lower ends) where the portion surrounded by the dotted line in FIG. 6 is actually visible is shown. Part of the part).
図6Aは、ピッチy≦min(a,b)を満足する場合を示す。ここで、min(a,b)は、aとbのうち大きくない方を表す。
FIG. 6A shows a case where the pitch y ≦ min (a, b) is satisfied. Here, min (a, b) represents the smaller of a and b.
(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.
