2. Description of the Related Art Conventionally, as a sunshade device for a building, there is known a device that shades a room by shielding the solar radiation entering the room from a window with a film-like body such as a sunshade sheet (for example, Patent Document 1, Patent Document 1). 2).
JP-A-11-166379 JP 2000-303640 A

しかし、このような日除けに用いられる布製の幕状体は布目(網目)が均一であるため、日射遮蔽機能を高めようとすれば、布目を細かくする必要があり、採光機能や通風機能を向上させようとすれば、布目を粗くする必要がある。このように日射遮蔽機能と、採光機能および通風機能は相反するものとなり、片方を向上させると片方が不利となる問題がある。   However, since the cloth curtains used for awnings have a uniform mesh (mesh), it is necessary to make the mesh finer if the solar shading function is to be improved, improving the lighting function and ventilation function. If it is going to make it, it is necessary to make a texture rough. Thus, the solar radiation shielding function, the daylighting function and the ventilation function are contradictory, and there is a problem that if one is improved, the other is disadvantageous.

そこで、この発明は、日射遮蔽機能と、採光機能および通風機能を満足できる日除けシートを提供することを目的とするものである。   Therefore, an object of the present invention is to provide an awning sheet that can satisfy the solar radiation shielding function, the daylighting function, and the ventilation function.

この目的を達成するため、請求項1の発明は、窓の日除けを行なうための網状生地製の日除けシートであって、部分的に網目間隔の異なった生地とすることで、日射遮蔽・採光・通風のバランスの取れた日除けを提供することを特徴とする。   In order to achieve this object, the invention of claim 1 is a awning sheet made of a reticulated cloth for awning a window, and is partially made of a cloth having a different mesh interval so as to block sunlight, Providing a well-balanced sunshade for ventilation.

また、請求項2の発明は、請求項1の日除けシートにおいて、庇の出寸法と日除けの位置関係から、網目間隔を決定することで日射遮蔽機能の低減を最小限にしつつ採光機能を向上させたことを特徴とする。   Further, the invention of claim 2 improves the daylighting function in the sunshade sheet of claim 1 by determining the mesh interval from the positional relationship between the projection size of the ridge and the shade and minimizing the reduction of the solar shading function. It is characterized by that.

請求項1,2の日除けシートによれば、日射遮蔽機能と、採光機能および通風機能を満足できる。   According to the awning sheets of claims 1 and 2, the solar shading function, the daylighting function and the ventilation function can be satisfied.

以下、この発明の実施の形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図1(a)において、建物1は室2を有し、室2の外壁3は窓(窓開口)4を有する。また、外壁3の上部には庇5が設けられている。尚、図1(a)は、窓4の窓ガラス(図示せず)等を開けたときの状態を示している。   In FIG. 1A, a building 1 has a room 2, and an outer wall 3 of the room 2 has a window (window opening) 4. A flange 5 is provided on the top of the outer wall 3. FIG. 1A shows a state when a window glass (not shown) of the window 4 is opened.

この外壁3と庇5との入隅には、窓4の上縁に沿って延びるシート巻取装置6が取り付けられている。このシート巻取装置6には、従来周知のシャッター巻取装置やスクリーン巻取装置を用いることができるので、その詳細な説明は省略する。   A sheet take-up device 6 extending along the upper edge of the window 4 is attached to the corner between the outer wall 3 and the flange 5. Since the sheet winding device 6 can be a conventionally known shutter winding device or screen winding device, detailed description thereof will be omitted.

このシート巻取装置6には、この発明に係る網目生地製の日除けシート7が巻取可能且つ下方に繰り出し可能に装着されている。また、日除けシート7は、図1(b)に示したように縦糸8と横糸9から網目状に形成されている。   A mesh fabric sunshade sheet 7 according to the present invention is mounted on the sheet winder 6 so that it can be wound and fed downward. The awning sheet 7 is formed in a mesh shape from the warp 8 and the weft 9 as shown in FIG.

この横糸9の間隔は上側の範囲Aが下側の範囲Bよりも広く設定されている。これにより、日除けシート7の範囲Aの網目7aは広く設定され、範囲Bの網目7bは範囲Aの網目7aよりも狭く設定されている。   The distance between the wefts 9 is set so that the upper range A is wider than the lower range B. As a result, the mesh 7a in the range A of the awning sheet 7 is set wider, and the mesh 7b in the range B is set narrower than the mesh 7a in the range A.

尚、範囲Aの広い網目7aは、夏場の所定の太陽高度と庇5の出寸法Lから、庇5で日射C1が遮られていることで直接に日射Cが当たらない部分に設定されている。この夏場の所定の太陽高度は、例えば、日射Cにより室2内の温度の上昇が急激に大きくなる時点、或いはそのピーク前の時間等を考慮して用いられる。また、範囲Bの狭い網目7bは、庇5で防げない日射Cの部分に設定されている。   Note that the wide mesh 7a in the range A is set to a portion where the solar radiation C1 is not directly hit by the solar radiation C1 being blocked by the firewood 5 from the predetermined sun altitude in summer and the projected dimension L of the firewood 5. . The predetermined solar altitude in summer is used in consideration of, for example, the time when the temperature rise in the room 2 suddenly increases due to solar radiation C or the time before the peak. The narrow mesh 7b in the range B is set to a portion of the solar radiation C that cannot be prevented by the ridge 5.

このような構成によれば、図1(b)に示したように日除けシート7の上側の範囲Aの網目7aは広く設定されているので、図1(a)に示したように日除けシート7で窓4を遮蔽したときに、日除けシート7の上側の範囲Aは矢印A1で示したように通気性と採光性が良好であり、日除けシート7の下側の範囲Bの網目7bは日射遮蔽性が良好となる。   According to such a configuration, as shown in FIG. 1 (b), the mesh 7a in the upper range A of the awning sheet 7 is set wide, so that the awning sheet 7 as shown in FIG. 1 (a). When the window 4 is shielded, the upper area A of the awning sheet 7 has good air permeability and daylighting as indicated by the arrow A1, and the mesh 7b of the lower area B of the awning sheet 7 is sunshielded. Property is improved.

この結果、日射Cにより室2内の温度の上昇が急激に大きくなる時点或いはそのピーク前の時間等において、日除けシート7で窓4を遮蔽したときに、日射遮蔽性機能を落とすことなく、通気性及び採光性を向上させることができるので、室2内は暑くなりにくく且つ室2内の暗さも軽減される。
(変形例1)
また、図2(a),図2(b)は、日除けシート7の上下の範囲A,A′に図1と同様な広い網目7aを設定し、範囲A,A′の網目7aを範囲Bの網目7bよりも広く設定した例を示したものである。
As a result, when the window 4 is shielded by the awning sheet 7 at the time when the temperature rise in the chamber 2 suddenly increases due to the solar radiation C or at the time before the peak, the ventilation function is not reduced. Therefore, the inside of the room 2 is hardly heated and the darkness in the room 2 is reduced.
(Modification 1)
2A and 2B, a wide mesh 7a similar to that shown in FIG. This shows an example in which the mesh is set wider than the mesh 7b.

この構成においては、窓4を窓ガラス10で閉じて、室2を外部と遮断したときに、窓ガラス10と日除けシート7との間の空間11の空気12が日射等により暖められて温度上昇すると、空間11内の空気12が矢印A2で示したように上昇して、日除けシート7の上側の範囲Aから矢印A3で示したように熱気として大気に放出される一方、日除けシート7の下側の範囲A′から比較的涼しい外気が矢印A4で示したように空間11内に流入する。   In this configuration, when the window 4 is closed with the window glass 10 and the chamber 2 is shut off from the outside, the air 12 in the space 11 between the window glass 10 and the awning sheet 7 is heated by solar radiation or the like and the temperature rises. Then, the air 12 in the space 11 rises as indicated by the arrow A2, and is released into the atmosphere as hot air from the upper range A of the shade sheet 7 as indicated by the arrow A3. From the side range A ′, relatively cool outside air flows into the space 11 as indicated by an arrow A4.

この結果、空間11の空気が暖まりにくいので、空間11から室2内に窓ガラス10を介して伝わる熱が軽減され、室2内が暑くなりにくい。   As a result, since the air in the space 11 is not easily warmed, heat transmitted from the space 11 into the chamber 2 through the window glass 10 is reduced, and the interior of the chamber 2 is not easily heated.

しかも、日除けシート7の上側の範囲Aは日射がないので、図2(b)に示したように範囲Aの網目7aを広くして、通気性と採光性を良くしても、室2内の温度上昇を抑制できる。また、日除けシート7の下側の範囲A′は日射があっても、図2(b)に示したように範囲A′の網目7aを広くすることで、比較的に涼しい空気が空間11に流入するので、通気性が良くなり、室2内の温度上昇を抑制できると共に、室2への採光性を向上させることができる。   In addition, since the upper area A of the awning sheet 7 does not have solar radiation, even if the mesh 7a of the area A is widened as shown in FIG. Temperature rise can be suppressed. In addition, even if the area A ′ below the sun protection sheet 7 is exposed to sunlight, relatively cool air is introduced into the space 11 by widening the mesh 7a of the area A ′ as shown in FIG. Since it flows in, the air permeability is improved, the temperature rise in the chamber 2 can be suppressed, and the daylighting property to the chamber 2 can be improved.

これらの結果、日除けシート7の上下の範囲A,A′に広い網目7aを設けることで、室2内の温度上昇を抑制しながら、室2への採光性を図1の場合より向上させることができる。
(使用例)
また、図2(a),図2(b)の建物1の窓ガラス10を開けて図3のようにして使用することにより、空気の浮力により日除けシート7の下側の範囲A′から冷気が矢印A4で示したように室2内に入り、日除けシート7の上側の範囲Aから室2内の熱気が矢印A3で示したように抜けるため、日除けシート7全体の日射遮蔽性能を落とすことなく、通風性能を向上させることが出来、室2内が暑くなりにくい。
As a result, by providing wide meshes 7a in the upper and lower ranges A and A 'of the sun protection sheet 7, the daylighting into the chamber 2 can be improved compared to the case of FIG. 1 while suppressing the temperature rise in the chamber 2. Can do.
(Example of use)
Further, by opening the window glass 10 of the building 1 shown in FIGS. 2 (a) and 2 (b) and using it as shown in FIG. Enters the chamber 2 as indicated by the arrow A4, and the hot air in the chamber 2 escapes from the upper range A of the sunscreen 7 as indicated by the arrow A3. Ventilation performance can be improved and the interior of the room 2 is unlikely to become hot.

しかも、図2(b)に示したように日除けシート7の上下の範囲A,A′に広い網目7aを設けることで、室2内の温度上昇を抑制しながら、室2への採光性を図1の場合より向上させることができる。   Moreover, as shown in FIG. 2 (b), by providing wide meshes 7a in the upper and lower areas A and A 'of the awning sheet 7, it is possible to provide daylighting performance to the chamber 2 while suppressing temperature rise in the chamber 2. This can be improved over the case of FIG.

以上説明したように、この発明の実施の形態の日除けシート7は、窓4の日除けを行なうための網状生地から形成されている。しかも、日除けシートは、部分的に網目間隔の異なった生地とすることで、日射遮蔽・採光・通風のバランスの取れた日除けを行うようにしている。   As described above, the awning sheet 7 according to the embodiment of the present invention is formed of a net-like cloth for awning the window 4. In addition, the awning sheet is partially made of cloth having different mesh intervals so as to perform awning with a good balance of solar shading, daylighting and ventilation.

また、この発明の実施の形態の日除けシート7において、庇5の出寸法Lと日除けの位置関係から、網目間隔を決定することで日射遮蔽機能の低減を最小限にしつつ採光機能を向上させている。   Further, in the sunshade sheet 7 according to the embodiment of the present invention, the daylighting function is improved while minimizing the reduction of the solar radiation shielding function by determining the mesh interval from the positional relationship between the projection dimension L of the ridge 5 and the sunshade.
