【発明の属する技術分野】
この発明は、窓の室外側に設ける遮光ルバーに関する。
【０００２】
【従来の技術】
夏期に窓から室内に太陽光が照射されると、その照射によって室内が高温になるため、種々の遮光装置が提供されている。例えば窓枠の内部にフインを並列に設け、フインを回動する遮光装置（実開昭50-63942号公報、実開昭52-20879号公報）、サッシ窓の室内側にカーテンやブラインドを取付ける遮光装置（実開昭61-152697 号公報）、庇の下に巻取式のシートを備え、シートを出し入れする遮光装置（実開昭62-85624号公報、実開昭64-41522号公報）、窓上部の外壁にルバーを起倒可能に取付けたり、伸縮式のルバーを取付ける遮光装置（例えば実公平4-32428 号公報）等が知られている。
【０００３】
また庇型遮光手段やルバー型遮光手段として、水平庇、水平ルバー、かざし、ルバー庇、格子庇、穴庇、垂直ルバー、垂直可動ルバー等が知られており、正しく設計したルバー庇や水平ルバーは、まさに太陽光が室内に入射しようとする限界の照射角度θに合わせられているのど、庇と同様の遮蔽効果を持ち、垂直ルバーは太陽が東から西にまわるにつれて、先ず遮光桟の間から光が漏れ初め、しばらくして再び遮蔽される。
格子ルバーは、基本的には水平フインによる照射角度θの遮蔽効果と、垂直ルバーの方位照射角度の遮蔽効果との重ね合わせと考えてよい。
【０００４】
【発明が解決しようとする課題】
カーテンやブラインドによる遮光手段にあっては、室内に太陽熱が取り込まれるため、断熱効果が半減してしまう問題点があるし、また通風を妨げたり、視界を遮ったりする問題点もあった。
また垂直ルバーにあっては、正面方向には効果が少なく、ＮＥとＮＷ向きか、又は可動型としない限り、完全な遮蔽が不可能になる問題点があるし、格子ルバーにあっては、太陽の低照射角時にはあまり効果がないので、水平ルバーより若干守備範囲の広がった遮光効果しか得るれない問題点があった。
【０００５】
夏期に窓から室内に太陽光が照射すると、その太陽熱によって室内の温度が高められ、特に南向きや西向きの部屋では相当の暑さになり、その部屋で長時間生活し得なくなる問題点があった。これらの部屋に冷房装置を取付け、冷房装置によって室内温度を低下すれば、長時間の生活も可能となるが、太陽熱によって上昇する室内温度分、余分に冷房エネルギーを必要とする問題点があった。
夏期の遮光手段を設けると、その分、冷房エネルギーを軽減し得るが、遮光手段により冬期も太陽光を遮断すると、太陽光による室内温度の上昇を妨げる問題点があった。
【０００６】
太陽熱による夏期室内温度の上昇、遮光による冬期室内温度の低下は、冷暖房装置によって調整されていたため、その分、余分に冷暖房エネルギーを消費し、電気代や燃料代が高くなる問題点があると共に、資源の無駄使いにもなる問題点があった。
そこでこの発明は、従来技術の有するこのような問題点に鑑みてなされたものであり、その目的とするところは、夏と冬の日照変化を考慮し、省エネルギー効果の高い遮光ルバーを提供することにある。
【０００７】

【００２１】
【発明の効果】
本発明による遮光ルバーは上記構造のとおりであるから、次に記載する効果を奏する。
建物の外壁より室外側に突出している庇の下面に沿って遮光ルバーを取付けるものであるから、太陽高度が高くなる夏期間において、太陽光を遮蔽することができるので、冷房負荷熱量を軽減することができるし、反対に、太陽高度が低くなる冬期間には太陽光を室内に採入れることにより、暖房負荷熱量を軽減することができる。即ち、年間を通して省エネルギー化に貢献する。
【００２２】
本発明による遮光ルバーは、工場で直線パネルと隅角パネル（出隅パネルや入隅パネル）の遮光パネルを組立て、各種遮光パネルに応じた枠体の構成材を枠構成材より切断しておき、現場で先ず枠体を組立て、その枠体を取付け、該枠体の直線開口部と隅角開口部に遮光パネルを順次嵌挿固定するものであるから、それらの取付けが能率的で、しかも簡単容易に取付け得るばかりか、取付け後の外観も良いし、遮光パネルを構成する遮光桟の厚さが小さく、しかも取付間隔も広いので、室内からの視界も良好である。
【００２３】
窓からの日射量は、１時間、１平方メートル当たり約５００キロカロリーにも及ぶが、本発明遮光ルバーの取付けにより窓が夏期間に日陰となるので、その日射量による冷房負荷熱量を節約することができる。特に東京より南の地域に使用した場合、遮蔽効率が上昇する。
本発明による遮光ルバーは上記実施例に限定されるものではなく、例えば庇の代わりに、外壁より突出するベランダにおいても、ベランダの外周部に沿って取付けることも可能である。

BACKGROUND OF THE INVENTION
The present invention relates to a light-shielding luber provided outside a window.
[0002]
[Prior art]
When sunlight is irradiated into the room from a window in the summer, the room becomes hot due to the irradiation, and various light-shielding devices are provided. For example, light shielding devices (in Japanese Utility Model Publication No. 50-63942 and Japanese Utility Model Publication No. 52-20879) in which fins are arranged in parallel inside the window frame and curtains and blinds are installed inside the sash window Light-shielding device (Japanese Utility Model Publication No. 61-152697), light-shielding device equipped with a retractable sheet under the cage and taking in and out the sheet (Japanese Utility Model Publication No. 62-85624, Japanese Utility Model Publication No. 64-41522) A light-shielding device (for example, Japanese Utility Model Publication No. 4-32428) is known in which a luber is attached to the outer wall of the upper part of the window so that it can be tilted up and down, and a telescopic luber is attached.
[0003]
Also known as vertical shading means and louver-type shading means are known as horizontal scissors, horizontal rubbers, hold-ups, louver scissors, lattice scissors, hole scissors, vertical rubles, vertical movable louvers, etc. Is exactly adjusted to the limit of the incident angle θ at which sunlight is going to enter the room, but it has the same shielding effect as that of a kite. The light begins to leak from and is shielded again after a while.
The lattice louver may basically be considered as a superposition of the shielding effect of the irradiation angle θ by the horizontal fin and the shielding effect of the azimuth irradiation angle of the vertical luber.
[0004]
[Problems to be solved by the invention]
The light shielding means using curtains and blinds has the problem that the heat insulation effect is halved because solar heat is taken into the room, and there are also problems that obstruct ventilation and obstruct the field of view.
In addition, in the vertical luber, there is a problem that the effect is not effective in the front direction, and it is impossible to completely shield unless it is in the NE and NW direction or the movable type. There is a problem that only a light-shielding effect with a slightly wider defense range than the horizontal luber can be obtained because the effect is not so great at low sun illumination angles.
[0005]
When sunlight shines through a window in the summer, the room temperature is raised by the solar heat, especially in rooms facing south or west, and it becomes extremely hot, making it impossible to live in that room for a long time. It was. If a cooling device is installed in these rooms and the room temperature is lowered by the cooling device, it will be possible to live for a long time, but there is a problem that extra cooling energy is required for the room temperature rising by solar heat. .
When the light shielding means in the summer is provided, the cooling energy can be reduced by that amount. However, if the sunlight is blocked in the winter by the light shielding means, there is a problem that prevents the indoor temperature from being increased by the sunlight.
[0006]
The increase in summer indoor temperature due to solar heat and the decrease in winter indoor temperature due to light shielding have been adjusted by the air conditioning unit, so there is a problem that extra heating and cooling energy is consumed, and electricity and fuel costs increase. There was also a problem that wasted resources.
Therefore, the present invention has been made in view of such problems of the prior art, and its object is to provide a light-shielding luber with high energy-saving effect in consideration of summer and winter sunshine changes. It is in.

In the summer, when sunlight is strong, we block out high-temperature sunlight, perform necessary lighting, increase the cooling effect in summer, and promote energy saving in the home. That is, since sunlight is reflected by the light shielding bar 8 and does not reach the window W, the cooling energy consumption, that is, the power cost is reduced by 10 to 20%.
In the winter when the irradiation angle θ of sunlight is low, the sunlight is inserted into the room without being blocked by the light shielding bar 8 of the ridge G, so that the room is warmed. Thereby, the heating load of 10 to 20% is reduced at the time of winter heating.

【The invention's effect】
Since the light-shielding louver according to the present invention has the above-described structure, the following effects can be obtained.
Since the light-blocking luber is attached along the lower surface of the ridge projecting from the outer wall of the building to the outdoor side, the sunlight can be shielded during the summer period when the solar altitude is high, thus reducing the cooling load heat quantity. On the other hand, in the winter period when the solar altitude is low, the amount of heating load heat can be reduced by taking sunlight indoors. In other words, it contributes to energy saving throughout the year.

The light shielding luver according to the present invention is constructed by assembling a light shielding panel of a straight panel and a corner panel (protruding corner panel or entering corner panel) at a factory, and cutting the frame components according to the various light shielding panels from the frame components. First, the frame is first assembled at the site, the frame is attached, and the light shielding panels are sequentially inserted and fixed in the linear openings and the corner openings of the frame. In addition to being easy and easy to install, the appearance after installation is good, the thickness of the light shielding bar constituting the light shielding panel is small, and the mounting interval is wide, so the view from the room is also good.

The amount of solar radiation from the window can reach about 500 kilocalories per square meter per hour. However, the installation of the shading luber of the present invention makes the window shade in the summer, so it is possible to save the cooling load heat due to the amount of solar radiation. it can. Especially when used in areas south of Tokyo, the shielding efficiency increases.
The light-shielding louver according to the present invention is not limited to the above-described embodiment. For example, a veranda protruding from the outer wall can be attached along the outer peripheral portion of the veranda instead of the ridge.
