Description

【0001】
【発明の属する技術分野】
本発明は、装飾模様の付された可視光透過性のフィルムが、可視光透過性の板ガラスの面に貼着されている日射調整ガラスに関する。
【0002】
【従来の技術】
このような日射調整ガラスでは、装飾模様の付されたフィルムを取り替えるだけで、例えば、異なる装飾模様のものや熱線透過率の異なる日射調整ガラスに簡単にリフォームすることができ、従来では、装飾模様を形成するのに顔料などを含むインクを使用し、その顔料などを含むインクをフィルム面に印刷して装飾模様を形成していた。
【0003】
【発明が解決しようとする課題】
しかし、この従来の技術では、フィルムへの装飾模様を顔料などを含むインクにより、つまり、可視光透過率の低い顔料などを含むインクにより形成するので、折角、可視光透過性を備えたフィルムと板ガラスを使用するにもかかわらず、装飾模様によって可視光透過率が低下して視界が悪くなるという欠点がある。
【0004】
本発明は、このような従来の問題点に着目したもので、その目的は、フィルムを取り替えるだけで、例えば、異なる装飾模様のものや熱線透過率の異なるものに簡単にリフォームすることができ、しかも、可視光透過率の低下を抑制することのできる日射調整ガラスを提供することである。
【0005】
【課題を解決するための手段】
請求項1の発明の特徴構成は、装飾模様の付された可視光透過性のフィルムが、可視光透過性の板ガラスの面に貼着されている日射調整ガラスであって、前記フィルムへの装飾模様が、そのフィルムの面に対して部分的に積層された高可視熱線反射膜により形成されているところにある。
【0006】
請求項1の発明の特徴構成によれば、装飾模様の付された可視光透過性のフィルムが、可視光透過性の板ガラスの面に貼着されているので、必要に応じてそのフィルムを取り替えることにより、例えば、異なる装飾模様の日射調整ガラスに簡単にリフォームすることができる。
そして、フィルムへの装飾模様が、そのフィルムの面に対して部分的に積層された高可視熱線反射膜により、つまり、従来の顔料などを含むインクに比べてはるかに可視光透過率の高い高可視熱線反射膜により形成されているので、可視光透過率の低下を抑制しながら熱線の透過を効果的に抑えることができる。
【0007】
請求項2の発明の特徴構成は、前記高可視熱線反射膜による装飾模様が縞模様であるところにある。
【0008】
請求項2の発明の特徴構成によれば、高可視熱線反射膜による装飾模様が縞模様であるから、板ガラスの全面積に対する高可視熱線反射膜の面積比率を容易に算出することができ、したがって、熱線透過率や可視光透過率の算出が容易、確実となり、所望する熱線透過率や可視光透過率を有する日射調整ガラスを容易に製造することができる。
【0009】
【発明の実施の形態】
本発明による日射調整ガラスの実施の形態を図面に基づいて説明する。
この日射調整ガラスは、図1および図2に示すように、可視光透過性の板ガラス1とその板ガラス1の面に貼着された可視光透過性のフィルム2で構成され、可視光透過性のフィルム2の面には、例えば、熱線を反射する高可視熱線反射膜3が部分的に積層され、その高可視熱線反射膜3によって、全体的には図3に示すような、また、顕微鏡的には図4に示すような装飾模様が形成されている。
この日射調整ガラスにおいて、例えば、板ガラス1は、その板厚が2.65〜3.2mm程度のフロートガラスが、フィルム2は、その厚みが25μm程度のポリエステル製の薄い膜が使用され、高可視熱線反射膜3は、ITO(インジウムティンオキサイド)、Ag、Au、Cu、Al、ZnO、あるいは、SnOなどを主成分とする金属製あるいは金属酸化物製の非常に薄い皮膜で、フィルム2の面にスパッタリングにより積層されている。
【0010】
この高可視熱線反射膜3は、フィルム2の全面にスパッタリングにより積層された後、幅D1を残して幅D2が削り取られ、その結果、幅D1の多数の線状の高可視熱線反射膜3が、幅D2の間隔を置いて縞模様を形成するように、板ガラス1の面に部分的に積層されている。
例えば、高可視熱線反射膜3の幅D1と、高可視熱線反射膜3間の幅D2は、熱線反射性能と装飾性(見栄え)から適宜決定され、その高可視熱線反射膜3の表面側が、ポリエステル製の保護膜4により覆われていて、このような構成のフィルム2が、接着剤により板ガラス1の全面に貼着されて日射調整ガラスが構成されている。
【0011】
〔別実施形態〕
(1)先の実施形態では、高可視熱線反射膜3により縞模様を形成した例を示したが、高可視熱線反射膜3による装飾模様については、特に縞模様に限るものではなく、例えば、図5に示すように、正方形の高可視熱線反射膜3を多数並べた碁盤の目のような模様をはじめとして種々の模様を形成することができる。
【0012】
(2)本発明による日射調整ガラスは、単板ガラスとして使用し得るのは勿論のこと、例えば、図6の(イ)に示すように、一対の板ガラス1,1において、両面間に多数のスペーサ(図示せず)を介在させて互いに対面配置し、両板ガラス1,1間の間隙部Vを減圧した真空複層ガラスなどの複層ガラスパネルPに使用することもでき、また、図6の(ロ)に示すように、両板ガラス1,1間の間隙部Vを空気層とする複層ガラスパネルPに使用することもできる。
【0013】
この図6の(イ)に示す真空複層ガラスでは、製造工程の関係から両板ガラス1,1の間隙部V側の面に高可視熱線反射膜3を有するフィルム2を貼着することはむずかしく、したがって、図示のように室内側板ガラス1の室内側の面に貼着するか、あるいは、室外側板ガラス1の室外側の面に貼着することになる。
それに対し、図6の(ロ)に示す複層ガラスでは、そのような制約がないため、図示のように室内側板ガラス1の間隙部V側の面は勿論のこと、室外側板ガラス1の間隙部V側の面にも、また、室内側板ガラス1の室内側の面、あるいは、室外側板ガラス1の室外側の面にも貼着することができる。ただし、フィルム2の取り替えを考えると、室内側板ガラス1の室内側の面か室外側板ガラス1の室外側の面に貼着するのが好ましい。
いずれの場合においても、室内側の板ガラス1に高可視熱線反射膜3を有するフィルム2を貼着すると、断熱効果を期待することができ、逆に室外側の板ガラス1に貼着すると、遮熱効果を期待することができる。
【0014】
さらに、図7に示すように、室内側の窓と室外側の窓が、その中間に間隙を有して配置される二重窓において、その板ガラス1に高可視熱線反射膜3を有するフィルム2を貼着することもできる。この図においては、室外側の窓の板ガラス1における室内側の面にフィルム2を貼着した例を示しているが、合計4枚ある板ガラス1のいずれにおいても、その室内側の面または室外側の面にフィルム2を貼着することができる。
そして、この二重窓においても、室内側の窓の板ガラス1に高可視熱線反射膜3を有するフィルム2を貼着すると、断熱効果を期待することができ、逆に室外側の窓の板ガラス1に貼着すると、遮熱効果を期待することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a solar control glass in which a visible light transmitting film with a decorative pattern is attached to a surface of a visible light transmitting plate glass.
[0002]
[Prior art]
In such a solar control glass, for example, by simply replacing a film with a decorative pattern, for example, it can be easily remodeled into a solar control glass having a different decorative pattern or a different heat ray transmittance. Was used to form a decorative pattern by using an ink containing a pigment or the like and printing the ink containing the pigment or the like on the film surface.
[0003]
[Problems to be solved by the invention]
However, in this conventional technique, since the decorative pattern on the film is formed with ink containing a pigment or the like, that is, with an ink containing a pigment or the like with a low visible light transmittance, a film having a visible angle and a film having visible light transmittance is formed. Despite the use of sheet glass, there is a drawback that the visible light transmittance is reduced due to the decorative pattern and visibility is deteriorated.
[0004]
The present invention focuses on such conventional problems, the purpose of which is to replace the film, for example, can be easily remodeled to a different decorative pattern or a different heat ray transmittance, for example, Moreover, an object of the present invention is to provide a solar control glass capable of suppressing a decrease in visible light transmittance.
[0005]
[Means for Solving the Problems]
A feature of the invention according to claim 1 is that the visible light transmitting film provided with the decorative pattern is a solar control glass attached to a surface of a visible light transmitting plate glass, and the decoration on the film is provided. The pattern is formed by the high visible heat ray reflective film partially laminated on the surface of the film.
[0006]
According to the characteristic structure of the first aspect of the present invention, since the visible light-transmitting film with the decorative pattern is attached to the surface of the visible light-transmitting plate glass, the film is replaced as necessary. Thereby, for example, it is possible to easily remodel the solar control glass with different decorative patterns.
The decorative pattern on the film is formed by a high visible heat ray reflective film partially laminated on the surface of the film, that is, a high visible light transmittance that is much higher than that of a conventional ink containing a pigment or the like. Since it is formed of the visible heat ray reflective film, transmission of heat rays can be effectively suppressed while suppressing a decrease in visible light transmittance.
[0007]
A feature of the invention according to claim 2 is that the decorative pattern formed by the high-visible heat ray reflective film is a striped pattern.
[0008]
According to the characteristic configuration of the second aspect of the present invention, since the decorative pattern formed by the high visible heat ray reflective film is a striped pattern, the area ratio of the high visible heat ray reflective film to the entire area of the plate glass can be easily calculated. In addition, the calculation of the heat ray transmittance and the visible light transmittance becomes easy and reliable, and the solar control glass having the desired heat ray transmittance and the visible light transmittance can be easily manufactured.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the solar control glass according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the solar control glass is composed of a visible light transmissive plate glass 1 and a visible light transmissive film 2 adhered to the surface of the plate glass 1. For example, a high-visible heat ray reflective film 3 that reflects heat rays is partially laminated on the surface of the film 2, and the high-visible heat ray reflective film 3 as a whole as shown in FIG. Has a decorative pattern as shown in FIG.
In the solar control glass, for example, the plate glass 1 is a float glass having a plate thickness of about 2.65 to 3.2 mm, and the film 2 is a thin film made of polyester having a thickness of about 25 μm. The heat ray reflective film 3 is a very thin film made of metal or metal oxide containing ITO (indium tin oxide), Ag, Au, Cu, Al, ZnO, or SnO 2 as a main component. It is laminated on the surface by sputtering.
[0010]
The high visible heat ray reflective film 3 is laminated on the entire surface of the film 2 by sputtering, and then the width D2 is cut off leaving the width D1. As a result, a large number of linear high visible heat ray reflective films 3 having the width D1 are formed. Are partially laminated on the surface of the sheet glass 1 so as to form a striped pattern at intervals of the width D2.
For example, the width D1 of the high-visible heat ray reflective film 3 and the width D2 between the high-visible heat ray reflective films 3 are appropriately determined from heat ray reflective performance and decorativeness (appearance). The film 2 having such a configuration, which is covered with a protective film 4 made of polyester, is adhered to the entire surface of the plate glass 1 with an adhesive to constitute a solar control glass.
[0011]
[Another embodiment]
(1) In the above embodiment, the example in which the striped pattern is formed by the high-visible heat ray reflective film 3 is described. However, the decorative pattern by the high-visible heat ray reflective film 3 is not particularly limited to the striped pattern. As shown in FIG. 5, various patterns can be formed, including a grid-like pattern in which a large number of square high-visible heat ray reflective films 3 are arranged.
[0012]
(2) The solar control glass according to the present invention can of course be used as a single glass sheet. For example, as shown in FIG. (Not shown) can be used for a double glazing panel P such as a vacuum double glazing in which the gap V between both glazings 1 and 1 is depressurized by interposing them (not shown). As shown in (b), the present invention can also be used for a double-glazed glass panel P in which a gap V between both glass sheets 1 and 1 has an air layer.
[0013]
In the vacuum insulating glass shown in FIG. 6A, it is difficult to attach the film 2 having the high visible heat ray reflective film 3 to the surface on the gap V side between the two glass sheets 1, 1 due to the manufacturing process. Therefore, as shown in the drawing, it is attached to the indoor side surface of the indoor side glass sheet 1 or is attached to the outdoor side surface of the outdoor side glass sheet 1.
On the other hand, in the case of the double glazing shown in FIG. 6B, since there is no such restriction, not only the surface of the indoor side glass sheet 1 on the gap portion V side as shown in FIG. It can be stuck to the surface on the side of the part V, the indoor surface of the indoor glass sheet 1, or the outdoor surface of the outdoor glass sheet 1. However, in consideration of replacement of the film 2, it is preferable to attach the film 2 to the indoor surface of the indoor glass sheet 1 or the outdoor surface of the outdoor glass sheet 1.
In any case, when the film 2 having the high-visible heat ray reflective film 3 is adhered to the indoor glass sheet 1, a heat insulating effect can be expected. Conversely, when the film 2 is adhered to the outdoor glass sheet 1, heat shielding is obtained. The effect can be expected.
[0014]
Further, as shown in FIG. 7, in a double window in which a window on the indoor side and a window on the outdoor side are arranged with a gap between them, a film 2 having a high visible heat ray reflective film 3 on its sheet glass 1 is provided. Can also be attached. In this figure, an example is shown in which the film 2 is adhered to the indoor side surface of the glass sheet 1 of the window on the outdoor side, but in any of the four glass sheets 1 in total, the indoor surface or the outdoor side is used. The film 2 can be stuck on the surface of.
Also in this double window, if the film 2 having the high visible heat ray reflective film 3 is adhered to the glass sheet 1 of the indoor window, a heat insulating effect can be expected, and conversely, the glass sheet 1 of the outdoor window can be expected. When it is adhered to, a heat shielding effect can be expected.
