【発明の属する技術分野】
本発明は、建物の採光部から漏れる光に誘引される害虫を少なくできる防虫採光板状部材及びこれを備えた防虫開閉窓に関する。
【０００２】
【従来の技術】
この種の防虫採光板状部材としては、特開平１−１２２９３５号公報に開示されたものがあり、図９は、これに開示された防虫採光板状部材で、色々な条件で作られた部材１〜部材４において、所定の波長の光透過を阻止する割合を示した説明図、図１０は、この部材を使って虫の誘引阻止がどれだけ行えたかを示す説明図である。
【０００３】
この防虫採光板状部材は、基材は、ガラスで形成されており、光透過阻止率が、２００〜４００ｎｍの波長の光に対して８５％以上であり、５５０〜７００ｎｍの波長の光に対して６０％以下となるように遮光剤をガラスに含有させたものである。具体的には、遮光剤にＡｓ２Ｏ３を０．０５〜０．４重量％含んだものとし、遮光材の組成や含有する割合を変えることで、部材１〜部材４を図９に示すような光透過阻止率を有するように形成したものである。

【発明が解決しようとする課題】
ところで前記した防虫採光板状部材は、虫の誘引が７８．１％〜８８．８％とかなり高いレベルで阻止できるものであった。しかし、防虫採光板状部材においては、その用途によっては、虫の誘引阻止をさらに高いレベルで要望されることがあり、特に、開閉が行われる窓などでは、この要望が強い場合があった。また、防虫採光板状部材は、建物全体として見たときを考慮すると、その意匠性も要求されることがあり、防虫採光板状部材が着色されることが好まれない場合もあった。
【０００７】
本発明は、上記事由に鑑みてなしたもので、その目的とするところは、虫の誘引阻止が向上できる防虫採光板状部材及びこれを用いた防虫開閉窓を提供することにある。
【０００８】
【課題を解決するための手段】
請求項１に係る発明の防虫採光板状部材は、建物の採光部に取り付けられる防虫採光板状部材において、建物の外部からの光を屈折させて建物の内部に取り込むとともに建物の内部からの光を建物の外部に放出しない凸凹面を備えたことを特徴とする。なお、建物の内部からの光を建物の外部に放出しないとは、建物の内部からの光１００％に対し、１０％程度以下の光しか建物の外部に放出しないものをいう。
【０００９】
請求項２に係る発明の防虫採光板状部材は、請求項１において、前記凸凹面は、建物の内部からの光を複数回反射させて前記建物の内部に前記光を放出するものであり、この凸凹面をプリズムにて形成したことを特徴とする。
【００１０】
請求項３に係る発明の防虫採光板状部材は、請求項１又は２において、前記防虫採光板状部材は、可視光短波長がカットされる処理が施されたものであり、前記凸凹面が建物の内部からの光を外部にわずかに放出しても、その放出された光は可視光短波長がカットされたものとなることを特徴とする。なお、可視光短波長とは、略４２０ｎｍ以下の波長の光をいう。
【００１１】
請求項４に係る発明の防虫採光板状部材は、請求項１又は２において、前記防虫採光板状部材は、紫外線がカットされる処理が施されたものであり、前記凸凹面が建物の内部からの光を外部にわずかに放出しても、その放出された光は紫外線がカットされたものとなることを特徴とする。なお、紫外線とは、略３８０ｎｍ以下の波長の光をいう。
【００１２】
請求項５に係る発明の防虫採光板状部材は、請求項１乃至４において、前記防虫採光板状部材を開閉する採光部に備えたことを特徴とする。
【００１３】
請求項６に係る発明の防虫開閉窓は、請求項１乃至４記載の防虫採光板状部材を開閉するとともに可視光短波長がカットできる窓に取付けたことを特徴とする。
【００１４】
請求項７に係る発明の防虫開閉窓は、請求項１乃至４記載の防虫採光板状部材を開閉するとともに紫外線がカットできる窓に取付けたことを特徴とする。
【００１５】
【発明の実施の形態】
本発明の実施の形態を図１、図２を用いて説明する。図１は防虫採光板状部材を建物の開閉する採光部たとえば、窓ガラスに備えた場合の要部断面図、図２は防虫採光板状部材の要部断面図である。
【００１６】
この防虫採光板状部材１は、ガラス材料や樹脂材料などで厚さ０．１ｍｍ〜３ｍｍ程度のシート状に形成されており、その片側面に建物の外部からの光を屈折させて建物の内部に取り込むとともに建物の内部からの光を建物の外部に放出しない凸凹面１ａを備えている。ここで凸凹面１ａは、所謂、プリズムにて形成されており、図２では、その凸凹面１ａの断面は、略直角二等辺三角形をなしている。また、凸凹面１ａと反対側の面は、略水平な面１ｂとなっている。そして、シート状に形成された防虫採光板状部材１は、凸凹面１ａを外側に向けて、建物の開閉する採光部である窓ガラス２に取り付けられている。なお、３は、建物の壁面を、４は建物内の照明を示していおり、この場合において照明４は、虫を誘引させる光を放つものである。
【００１７】
このように構成された防虫採光板状部材１を建物の開閉する採光部たとえば、窓ガラス２に用いると、建物の外部からの光と、建物の内部からの光は、各々次のようになる。まず、建物の外部からの光は、窓ガラス２を通過して、さらに防虫採光板状部材１の凸凹面１ａで屈折して建物の内部に取り込まれることになる。この状態を図２のＸで示しており、このものでは、外光の約７０％の光が内部に取り込まれるものとなる。また、建物の内部からの光は、防虫採光板状部材１の略水平な面１ｂから防虫採光板状部材１の中に入り、やがてこの光は凸凹面１ａに当たるものとなる。そして、この凸凹面で２回、反射して建物の内部に再度光が放出されるものとなる。この状態を図２のＹで示しており、このものでは、内部から来た光が外部に放出されるのは、約５％となる。
【００１８】
そして、このときにおいて、どれだけの虫の誘引を阻止できたかを示す虫の誘引阻止率は、我々の実験結果によると８２％となった。なお、この場合において、虫の誘引阻止率は、以下の通りに規定している。
虫の誘引阻止率＝［（Ａ−Ｂ）／Ａ×１００］
Ａ：防虫採光板状部材１を用いなかったときに集まる昆虫数
Ｂ：防虫採光板状部材１を用いたときに集まる昆虫数
この実施の形態によると、建物の外部からの光を屈折させて建物の内部に取り込むとともに建物の内部からの光を建物の外部に放出しない凸凹面１ａを備えたことにより、建物の内部からの光が約５％程度しか、外部に放出されないので、これにより虫の誘引阻止が向上できるものとなる。
【００１９】
また、凸凹面１ａは、建物の内部からの光を複数回反射させて建物の内部に光を放出するものであり、この凸凹面１ａをプリズムにて形成したことにより、凸凹面１ａを簡単に構成することができるとともに、建物の内部に再度光が放出されるので、建物の内部が明るくなり、照明などから放出された光を有効に活用することができる。さらに、防虫採光板状部材１を開閉する採光部、例えば、窓ガラスに備えることにより、窓ガラスを開閉したときに虫が侵入することを低減できるものとなる。
【００２０】
なお、凸凹面の形状は、図２に示したもの以外に、図３に示した四角錐のものや図４に示した再帰反射型プリズムを形成するための形状のものでもかまわない。ここで、図３の形状のものでは、建物の外部からの光は、Ｘで示されるように防虫採光板状部材１の凸凹面１ａで屈折して建物の内部に取り込まれることになり、外光の約７２％の光が内部に取り込まれるものとなる。また、建物の内部からの光は、防虫採光板状部材１の略水平な面１ｂから防虫採光板状部材１の中に入り、やがてこの光は凸凹面１ａに当たるものとなり、凸凹面で複数回、反射して建物の内部に再度光を放出するものとなる。この状態を示したものが図２のＹであり、このものでは、内部から来た光が外部に放出されるのは、約３％となる。
【００２１】
また、凸凹面の形状が図４のものでは、建物の外部からの光の約７０％の光が内部に取り込まれるものとなる。また、建物の内部からの光りが外部に放出されるのは、約１％となる。
【００２２】
なお、防虫採光板状部材１は、図５に示したもののように、建物の開閉する採光部たとえば、窓ガラス２の外側に設けられていても良い。このものにおいては図１に示したものと略同じ程度の虫の誘引阻止ができるものとなる。
【００２３】
また、従来は、窓ガラスなどで、虫を誘引する特定の波長をカットする処理を施して虫の誘引阻止を行っていたものがあったが、このものでは窓ガラスが着色してしまうことがあった。しかし、図１〜図５を用いて説明した防虫採光板状部材１は、防虫採光板状部材１を着色しないでも虫の誘引阻止が向上できるものであり、このために建物全体の意匠性を向上できるものとなる。
【００２４】
次に、この実施の形態の第１の応用例を説明する。図６は、この応用例を示す図で、防虫採光板状部材１を建物の開閉する採光部たとえば、窓ガラス２に備えた場合の要部断面図である。この応用例は、図５を用いて説明したものの窓ガラス２の構成を変えたものである。図において２ａは、窓ガラス２を可視光短波長がカットできるように処理したものである。通常この処理は、ガラスの表面に、可視光短波長がカットできるフイルムを貼り合わせたり、可視光短波長がカットできる蒸着膜を形成したり、あるいは、ガラスそのものを可視光短波長がカットできる組成にするなどの方法が取られる。
【００２５】
このように構成された防虫開閉窓は、可視光短波長がカットされる処理が施されているので、凸凹面１ａが建物の内部からの光を外部にわずかに放出しても、その放出された光は可視光短波長がカットされたものとなるので、さらに虫を寄せ付けにくいものとなり、このものにおいては、図５を用いて説明したもののにおける虫の誘引阻止率８２％以上の虫の誘引阻止ができるものとなる。なお、図５において、防虫採光板状部材１に図４で説明したものを用いると、防虫開閉窓は、建物の内部からの光を外部にさらに放出しにくくなるので我々の実験によると約１００％の虫の誘引阻止ができるものとなった。また、誘引阻止が下がるが、窓ガラス２に施した処理として、紫外線がカットできるようにしたものでもかまわない。
【００２６】
次に、この実施の形態の第２の応用例を説明する。図７は、この応用例を示す図で、防虫採光板状部材１を建物の開閉する採光部たとえば、窓ガラス２に備えた場合の要部断面図である。この応用例は、図１を用いて説明したものの窓ガラス２の構成を変えたものである。すなわち防虫採光板状部材１を可視光短波長がカットできるように処理したものである。通常この処理は、防虫採光板状部材１の表面に、可視光短波長がカットできるフイルムを貼り合わせたり、可視光短波長がカットできる蒸着膜を形成したり、あるいは、防虫採光板状部材１そのものを可視光短波長がカットできる組成にするなどの方法が取られ、図は防虫採光板状部材１の両側表面に、可視光短波長がカットできるフイルムを貼り合わせたものである。
【００２７】
このように構成された防虫開閉窓は、可視光短波長がカットされる処理が施されているので、凸凹面１ａが建物の内部からの光を外部にわずかに放出しても、その放出された光は可視光短波長がカットされたものとなるので、さらに虫を寄せ付けにくいものとなり、このものの場合は、我々の実験結果によると約９９％の虫の誘引阻止ができるものとなり、図１を用いて説明したもののにおける虫の誘引阻止率８２％に対してかなり良くできるものとなる。なお、ここでは防虫採光板状部材１を可視光短波長がカットできるように処理したもので説明したが、これは紫外線がカットできるようにしたものでもかまわない。この場合における虫の誘引阻止率は、約９６％となった。
【００２８】
次に、この実施の形態の第３の応用例を説明する。図８は、この応用例を示す図で、防虫採光板状部材１を建物の開閉する採光部たとえば、窓ガラス２の外側に備えた場合の要部断面図である。この応用例は、防虫採光板状部材１として図３に示したものを使用している。その他の図１を用いて説明したものと同一の構成部材には同一符号を付すことにより説明を省略する。このものは、防虫採光板状部材１の略水平な面１ｂを紫外線がカットできるように処理し、さらに窓ガラス２の建物の内側面を紫外線がカットできるように処理したものである。通常この処理は、防虫採光板状部材１や窓ガラス２の表面に、紫外線がカットできるフイルムを貼り合わせたり、紫外線がカットできる蒸着膜を形成したり、あるいは、防虫採光板状部材１や窓ガラス２そのものを紫外線がカットできる組成にするなどの方法が取られる。そして、ここでは紫外線がカットできるフイルムを防虫採光板状部材１の略水平な面１ｂと窓ガラス２の内側表面に貼り合わせている。
【００２９】
このように構成された防虫開閉窓は、我々の実験結果によると約９５％の虫の誘引阻止ができるものとなる。なお、もう少し虫の誘引阻止を上げるために、防虫採光板状部材１や窓ガラス２に施した処理として、可視光短波長がカットできるようにしたものでもかまわない。
【００３０】
なお、第１〜第３の応用例において紫外線とは、略３８０ｎｍ以下の波長の光をいい、可視光短波長とは、略４２０ｎｍ以下の波長の光をいう。
【００３１】

[0002]
[Prior art]
As this kind of insect-controlling plate member, there is one disclosed in JP-A-1-122935. FIG. 9 is a diagram showing the insect-controlling member plate member disclosed in this publication, which is manufactured under various conditions. FIG. 10 is an explanatory diagram showing a ratio of blocking light transmission of a predetermined wavelength in the first to fourth members, and FIG. 10 is an explanatory diagram showing how much the member can be used to prevent the attraction of insects.

JP-A-1-122935
[Problems to be solved by the invention]
By the way, the above-mentioned insect-proof daylighting plate-like member was able to prevent insect attraction at a considerably high level of 78.1% to 88.8%. However, depending on the application of the insect-proof daylighting plate-like member, there is a case where a higher level of prevention of insect attraction is demanded. In particular, there is a case where this demand is particularly strong in windows that are opened and closed. In addition, in consideration of the insect-controlling light-collecting plate member when viewed as a whole building, its design may be required, and it may not be preferable that the insect-controlling light-collecting plate member is colored.
[0007]
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an insect-proof daylighting plate-like member capable of improving prevention of insect attraction and an insect-proof opening / closing window using the same.
[0008]

[0014]
According to a seventh aspect of the present invention, there is provided an insect-resistant opening / closing window, wherein the insect-resistant daylighting plate-like member according to any one of the first to fourth aspects is opened and closed and attached to a window capable of cutting off ultraviolet rays.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view of a main part when an insect-controlling plate member is provided in a daylighting unit for opening and closing a building, for example, a window glass, and FIG. 2 is a cross-sectional view of a main part of the insect-controlling plate member.
[0016]
The insect-proof daylighting plate-like member 1 is formed of a glass material, a resin material, or the like into a sheet having a thickness of about 0.1 mm to 3 mm. And an uneven surface 1a that does not emit light from inside the building to the outside of the building. Here, the uneven surface 1a is formed by a so-called prism, and in FIG. 2, the cross section of the uneven surface 1a forms a substantially right-angled isosceles triangle. The surface opposite to the uneven surface 1a is a substantially horizontal surface 1b. The insect-proof daylighting plate-like member 1 formed in a sheet shape is attached to a window glass 2 which is a daylighting part for opening and closing a building, with the uneven surface 1a facing outward. Reference numeral 3 indicates a wall surface of the building, and reference numeral 4 indicates illumination in the building. In this case, the illumination 4 emits light that attracts insects.
[0017]
When the insect-proof daylighting plate-like member 1 configured as described above is used for a daylighting section for opening and closing a building, for example, a window glass 2, light from the outside of the building and light from the inside of the building are as follows. . First, light from the outside of the building passes through the window glass 2, and is further refracted by the uneven surface 1 a of the insect-proof light-collecting plate-like member 1 and is taken into the building. This state is indicated by X in FIG. 2. In this state, about 70% of the external light is taken in. Further, light from the inside of the building enters the insect-controlling light collecting plate-like member 1 from the substantially horizontal surface 1b of the insect-controlling light collecting plate-like member 1, and this light eventually hits the uneven surface 1a. Then, the light is reflected twice by the uneven surface and emitted again into the interior of the building. This state is indicated by Y in FIG. 2, in which about 5% of the light coming from inside is emitted to the outside.
[0018]
At this time, the insect attraction inhibition rate, which indicates how much insect attraction was inhibited, was 82% according to our experimental results. In this case, the insect attraction inhibition rate is defined as follows.
Insect retraction rate = [(AB) / A x 100]
A: The number of insects that gather when the insect-controlling plate member 1 is not used B: The number of insects that gather when the insect-controlling plate member 1 is used According to this embodiment, light from outside the building is refracted. The provision of the uneven surface 1a that takes in the interior of the building and does not emit light from the interior of the building to the outside of the building allows only about 5% of the light from the interior of the building to be emitted to the outside. Can be prevented from being attracted.
[0019]
The uneven surface 1a reflects light from inside the building a plurality of times and emits light into the building. By forming the uneven surface 1a by a prism, the uneven surface 1a can be easily formed. In addition to the configuration, the light is emitted again to the inside of the building, so that the inside of the building becomes bright, and the light emitted from the lighting and the like can be effectively used. Furthermore, by providing a daylighting unit that opens and closes the insect-proof daylighting plate-like member 1, for example, a windowpane, it is possible to reduce the invasion of insects when the windowpane is opened and closed.
[0020]
The shape of the uneven surface may be the shape of the quadrangular pyramid shown in FIG. 3 or the shape for forming the retroreflective prism shown in FIG. 4, other than the shape shown in FIG. Here, in the case of the shape shown in FIG. 3, light from the outside of the building is refracted by the uneven surface 1a of the insect-proof light-collecting plate-like member 1 as shown by X, and is taken into the inside of the building. About 72% of the light is taken in. Further, light from the inside of the building enters the insect-controlling light-collecting plate-like member 1 from the substantially horizontal surface 1b of the insect-controlling light-collecting plate-like member 1, and eventually reaches the uneven surface 1a. Then, the light is reflected and emitted again into the interior of the building. This state is indicated by Y in FIG. 2. In this case, about 3% of the light coming from inside is emitted to the outside.
[0021]
When the shape of the uneven surface is that shown in FIG. 4, about 70% of the light from the outside of the building is taken into the inside. Also, about 1% of the light emitted from inside the building is emitted to the outside.
[0022]
Note that the insect-proof daylighting plate-like member 1 may be provided on a daylighting part that opens and closes the building, for example, outside the window glass 2 as shown in FIG. In this case, almost the same degree of insect attraction as that shown in FIG. 1 can be prevented.
[0023]
Also, in the past, there was a window glass or the like in which a process of cutting a specific wavelength for attracting insects was performed to prevent the attracting of insects, but in this case, the window glass may be colored. there were. However, the insect-controlling light-collecting plate-like member 1 described with reference to FIGS. 1 to 5 can improve the prevention of insects from being attracted without coloring the insect-controlling light-collecting plate-like member 1. It can be improved.
[0024]
Next, a first application example of this embodiment will be described. FIG. 6 is a view showing this application example, and is a cross-sectional view of a main part in a case where the insect-proof daylighting plate-like member 1 is provided on a daylighting section for opening and closing a building, for example, a window glass 2. This application example is obtained by changing the configuration of the window glass 2 described with reference to FIG. In the figure, reference numeral 2a denotes a window glass 2 which has been processed so as to cut visible light short wavelengths. Usually, this treatment is performed by bonding a film capable of cutting visible light short wavelength to a glass surface, forming a vapor deposition film capable of cutting visible light short wavelength, or a composition capable of cutting visible light short wavelength of glass itself. And the like.
[0025]
Since the insect repellent opening / closing window configured as described above is subjected to a process of cutting visible light short wavelengths, even if the uneven surface 1a slightly emits light from the inside of the building to the outside, the light is emitted. The resulting light has a shorter visible light wavelength and is therefore more difficult to attract insects. In this case, the insect attractant having an insect attraction inhibition rate of 82% or more described in FIG. 5 is used. It can be stopped. In FIG. 5, when the insect-proof daylighting plate-shaped member 1 described with reference to FIG. 4 is used, the insect-proof opening / closing window becomes difficult to further emit light from the inside of the building to the outside. % Of insects can be prevented. In addition, although the prevention of the attraction is reduced, the treatment applied to the window glass 2 may be a treatment capable of cutting ultraviolet rays.
[0026]
Next, a second application example of this embodiment will be described. FIG. 7 is a view showing this application example, and is a cross-sectional view of a main part in a case where the insect-proof daylighting plate-like member 1 is provided in a daylighting section for opening and closing a building, for example, a window glass 2. This application example is a modification of the window glass 2 described with reference to FIG. That is, the insect-proof daylighting plate-shaped member 1 is processed so that a short wavelength of visible light can be cut. Usually, this treatment is performed by attaching a film capable of cutting visible light short wavelength, forming a vapor deposition film capable of cutting visible light short wavelength on the surface of the insect-proof light collecting plate-like member 1, In this case, a film capable of cutting visible light short wavelengths is attached to both surfaces of the insect-controlling light-collecting plate-like member 1 in such a way that the composition itself can be cut into visible light short wavelengths.
[0027]
Since the insect repellent opening / closing window configured as described above is subjected to a process of cutting visible light short wavelengths, even if the uneven surface 1a slightly emits light from the inside of the building to the outside, the light is emitted. Since the short-wavelength light is cut off, the light becomes more difficult to attract insects. In this case, according to our experimental results, it is possible to prevent approximately 99% of the insects from being attracted. Can be considerably improved with respect to the insect attraction inhibition rate of 82%. Here, the insect-proof daylighting plate-like member 1 has been described as having been processed so as to cut short wavelengths of visible light. However, this may be one in which ultraviolet rays can be cut. In this case, the insect attraction prevention rate was about 96%.
[0028]
Next, a third applied example of this embodiment will be described. FIG. 8 is a view showing this application example, and is a cross-sectional view of a main part in a case where an insect-proof daylighting plate-like member 1 is provided on a daylighting part for opening and closing a building, for example, outside a window glass 2. In this application example, the one shown in FIG. The same components as those described with reference to FIG. 1 are denoted by the same reference numerals, and description thereof is omitted. In this example, the substantially horizontal surface 1b of the insect-proof daylighting plate-like member 1 is treated so that ultraviolet rays can be cut off, and the inside surface of the window glass 2 of the building is further treated so that ultraviolet rays can be cut off. Usually, this treatment is performed by laminating a film capable of cutting ultraviolet light, forming a vapor-deposited film capable of cutting ultraviolet light on the surface of the insect-proof daylighting plate member 1 or the window glass 2, or forming the insect-proof daylighting plate member 1 or the window. For example, a method of making the glass 2 itself into a composition capable of cutting ultraviolet rays is used. Here, a film capable of cutting ultraviolet rays is attached to the substantially horizontal surface 1b of the insect-proof daylighting plate member 1 and the inner surface of the window glass 2.
[0029]
According to our experimental results, the insect repellent opening / closing window configured as described above can prevent about 95% of insects from being attracted. In order to further prevent the insects from being attracted, a treatment that is performed on the insect-proof light-collecting plate-like member 1 or the window glass 2 so as to cut short wavelengths of visible light may be used.
[0030]
In the first to third application examples, ultraviolet light refers to light having a wavelength of approximately 380 nm or less, and visible light short wavelength refers to light having a wavelength of approximately 420 nm or less.
[0031]
