本願は、２０１９年２月７日に日本で出願された特願２０１９－２０７１６号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a daylighting device.
The present application claims priority based on Japanese Patent Application No. 2019-20716 filed in Japan on February 7, 2019, the contents of which are incorporated herein by reference.
特許文献１には導光フィルム１１と、導光フィルム１１が固定されるガラス又はアクリル製の透光板１６と、透光板１６をパネルのフレーム２に固定するクイックリリース機構１７とを備える導光装置１ｅが開示されている。透光板１６には、パネル側の第１面に導光フィルム１１が固定され、パネルとは反対側の第２面にクイックリリース機構１７が固定される。クイックリリース機構１７は、パネル厚み方向におけるパネルから最も離れたフレーム２の端面に取り付けられている。
Patent Document 1 includes a light guide film 11, a transparent plate 16 made of glass or acrylic to which the light guide film 11 is fixed, and a quick release mechanism 17 for fixing the transparent plate 16 to the frame 2 of the panel. An optical device 1e is disclosed. The light guide film 11 is fixed to the first surface on the panel side of the translucent plate 16, and the quick release mechanism 17 is fixed to the second surface on the side opposite to the panel. The quick release mechanism 17 is attached to the end surface of the frame 2 that is farthest from the panel in the panel thickness direction.
しかしながら、特許文献１に記載された構成では、導光装置（以下、これを採光装置と呼んでもよい）が、少なくともフレーム及びクイックリリース機構の厚み分、パネルから厚み方向に突出し、特に、クイックリリース機構は、フレームから突出している。このため、パネルを移動させた際に、フレームから突出したクイックリリース機構が周囲の部材と干渉し、パネルの可動性が低下する可能性がある、との課題があった。
However, in the configuration described in Patent Document 1, the light guide device (hereinafter, this may be referred to as a daylighting device) protrudes in the thickness direction from the panel by at least the thickness of the frame and the quick release mechanism, and particularly the quick release. The mechanism projects from the frame. For this reason, when the panel is moved, the quick release mechanism protruding from the frame interferes with surrounding members, which may reduce the mobility of the panel.
本発明の一つの態様は、上記課題に鑑みなされたものであって、設置対象となるパネルの可動性の低下を抑制できる採光装置を提供することを目的とする。
One aspect of the present invention has been made in view of the above problems, and an object of the present invention is to provide a daylighting device capable of suppressing a decrease in mobility of a panel to be installed.
本発明の一態様の採光装置は、パネルから入光する入射光の角度を変えて出射光として出光する採光フィルムと、少なくとも採光フィルムの上辺の一部を含む端部に取り付けられ、採光フィルムの端部を覆って保護する端部保護部材と、端部保護部材に取り付けられ、端部保護部材をパネルに貼り付ける第１の両面粘着剤と、を備える。
A daylighting device of one embodiment of the present invention is attached to an end portion including at least a part of an upper side of a daylighting film and a daylighting film that emits light as outgoing light by changing an angle of incident light entering from a panel. An end protection member that covers and protects the end, and a first double-sided adhesive that is attached to the end protection member and that attaches the end protection member to the panel are provided.

According to one aspect of the present invention, it is possible to provide a daylighting device that does not impair the movability of the panel to be installed.
以下、本発明の実施の形態について、図面を参照しながら説明する。
Embodiments of the present invention will be described below with reference to the drawings.
［第１の実施の形態］
図１に本実施の形態における採光装置１００を示す。また図２は、図１のＩＩ－ＩＩの概略断面図である。図１に示すように採光装置１００は、パネル１０１から入光する入射光１０３の角度を変えて出射光１０４として出光する採光フィルム１０５を備える。 [First Embodiment]
FIG. 1 shows adaylighting device 100 according to the present embodiment. 2 is a schematic sectional view taken along line II-II in FIG. As shown in FIG. 1, the daylighting device 100 includes a daylighting film 105 that emits light as outgoing light 104 by changing the angle of incident light 103 entering from the panel 101.
図１に本実施の形態における採光装置１００を示す。また図２は、図１のＩＩ－ＩＩの概略断面図である。図１に示すように採光装置１００は、パネル１０１から入光する入射光１０３の角度を変えて出射光１０４として出光する採光フィルム１０５を備える。 [First Embodiment]
FIG. 1 shows a
室外からの入射光１０３は、パネル１０１の室内側に設置された採光装置１００によって室内への出射光１０４として出射される。パネル１０１は、例えば建物や乗り物の窓などに使用される透光性を有する板状のガラスや樹脂などである。またパネル１０１は、パネル１０１の全周に設けられパネル１０１の開閉を可能とするサッシなどの枠１０２によって支えられる。
The incident light 103 from the outside is emitted as the emitted light 104 to the room by the daylighting device 100 installed on the indoor side of the panel 101. The panel 101 is, for example, translucent plate-shaped glass or resin used for windows of buildings or vehicles. Further, the panel 101 is supported by a frame 102 such as a sash provided around the entire circumference of the panel 101 and capable of opening and closing the panel 101.
採光装置１００は、少なくとも採光フィルム１０５の上辺の一部を含む端部に取り付けられ、採光フィルム１０５の端部を覆って保護する端部保護部材１０６，１０８を備える。また採光装置１００は、端部保護部材１０６，１０８に取り付けられ、端部保護部材１０６，１０８をパネル１０１に貼り付ける両面粘着剤２０３，２０４を備える。
The lighting device 100 includes end protection members 106 and 108 that are attached to an end portion including at least a part of the upper side of the lighting film 105 and cover and protect the end portion of the lighting film 105. Further, the daylighting device 100 includes double- sided adhesives 203 and 204 attached to the end protection members 106 and 108 and sticking the end protection members 106 and 108 to the panel 101.
また端部保護部材１０６，１０８に設けられた溝２１１，２１２に採光フィルム１０５は挿入される。採光フィルム１０５は、入光する入射光１０３の角度を変えて出射光１０４とするプリズム層と、剛性を担保するためなどに図示せぬ基材とを備えている。
Further, the daylighting film 105 is inserted into the grooves 211 and 212 provided in the end protection members 106 and 108. The daylighting film 105 includes a prism layer that changes the angle of the incident light 103 that enters to be the emitted light 104, and a base material (not shown) for ensuring rigidity.
採光フィルム１０５には、設置される際の鉛直方向の上側に孔１０７Ａ，１０７Ｂ，１０７Ｃ（１０７）が設けられている。また端部保護部材１０６には、孔１０７Ａ，１０７Ｂ，１０７Ｃに対応する突部２０２Ａ，２０２Ｂ，２０２Ｃ（２０２）が設けられている。なお突部２０２Ａ，２０２Ｂに関しては図示していない。
-The daylighting film 105 is provided with holes 107A, 107B, 107C (107) on the upper side in the vertical direction when the film is installed. Further, the end protection member 106 is provided with projections 202A, 202B, 202C (202) corresponding to the holes 107A, 107B, 107C. The projections 202A and 202B are not shown.
図１において端部保護部材１０６は採光フィルム１０５の上辺の全体を覆っているが、端部保護部材１０６は採光フィルム１０５の上辺の一部を覆っていればよいものとする。同様に図１において端部保護部材１０８は採光フィルム１０５の下辺の全体を覆っているが、端部保護部材１０８は採光フィルム１０５の下辺の一部を覆っていればよいものとする。
In FIG. 1, the edge protection member 106 covers the entire upper side of the daylighting film 105, but the edge protection member 106 may cover a part of the upper side of the daylighting film 105. Similarly, in FIG. 1, the edge protection member 108 covers the entire lower side of the daylighting film 105, but it is sufficient that the edge protection member 108 covers a part of the lower side of the daylighting film 105.
端部保護部材１０６は、採光装置１００がパネル１０１に貼り付けられた状態においてパネル１０１側となる端部保護部材１０６Ａと、室内側となる端部保護部材１０６Ｂとに分離する。例えば突部２０２は端部保護部材１０６Ａに設けられ、端部保護部材１０６Ｂには突部２０２に対応する孔部又は凹部が設けられる場合、端部保護部材１０６Ａは端部保護部材１０６Ｂを固定することができる。なお端部保護部材１０６Ｂの外周につめ部が設けられていて、端部保護部材１０６Ｂは端部保護部材１０６Ａにはめ込むようにして固定されてもよい。
The end protection member 106 is separated into an end protection member 106A on the panel 101 side and an end protection member 106B on the indoor side when the lighting device 100 is attached to the panel 101. For example, when the projection 202 is provided on the end protection member 106A and the end protection member 106B is provided with a hole or a recess corresponding to the projection 202, the end protection member 106A fixes the end protection member 106B. be able to. A pawl may be provided on the outer periphery of the end protection member 106B, and the end protection member 106B may be fixed by being fitted into the end protection member 106A.
端部保護部材１０６が端部保護部材１０６Ａ，１０６Ｂに分離可能であるため、採光装置１００がパネル１０１に設置される際に、端部保護部材１０６Ａが両面粘着剤２０３によって固定されうる。これにより、パネル１０１に対する採光装置１００の設置位置が決められる。
Since the end protection member 106 can be separated into the end protection members 106A and 106B, the end protection member 106A can be fixed by the double-sided adhesive 203 when the daylighting device 100 is installed on the panel 101. Thereby, the installation position of the daylighting device 100 with respect to the panel 101 is determined.
採光装置１００がパネル１０１に設置される詳細な手順としては、端部保護部材１０６Ａがパネル１０１に固定された後、端部保護部材１０８が両面粘着剤２０４によってパネル１０１に固定される。次に孔１０７と突部２０２とがそれぞれ迎合することで採光フィルム１０５が端部保護部材１０６Ａに支持される。この場合は端部保護部材１０６の内側に設けられた突部２０２が採光フィルム１０５を支持する支持部となる。なお支持部を内側に設け、支持部を隠すことで採光装置１００の外観を整え、採光装置１００を設置した場合にもパネル１０１の外観を損ねにくくすることができる。
As a detailed procedure for installing the lighting device 100 on the panel 101, after the end protection member 106A is fixed to the panel 101, the end protection member 108 is fixed to the panel 101 by the double-sided adhesive 204. Next, the hole 107 and the protrusion 202 are brought into contact with each other, so that the daylighting film 105 is supported by the end protection member 106A. In this case, the protrusion 202 provided inside the end protection member 106 serves as a support portion that supports the daylighting film 105. It should be noted that by providing the support portion inside and hiding the support portion, the appearance of the daylighting device 100 can be adjusted, and even when the daylighting device 100 is installed, the appearance of the panel 101 can be less likely to be damaged.
なお採光フィルム１０５が端部保護部材１０６Ａに支持される際、端部保護部材１０８に採光フィルム１０５を挿入するために採光フィルム１０５を曲げる必要がある。次に端部保護部材１０６Ｂに設けられた突部２０２に対応する孔部又は凹部と、突部２０２とが迎合することで端部保護部材１０６Ｂが端部保護部材１０６Ａに固定される。
When the daylighting film 105 is supported by the edge protection member 106A, it is necessary to bend the daylighting film 105 in order to insert the daylighting film 105 into the edge protection member 108. Next, the hole or recess corresponding to the projection 202 provided on the end protection member 106B and the projection 202 come into contact with each other, whereby the end protection member 106B is fixed to the end protection member 106A.
以上のように本実施の形態における採光装置１００では、端部保護部材１０６，１０８を両面粘着剤２０３，２０４によって、枠１０２ではなくパネル１０１に貼り付けるため、パネル１０１の可動性を損なわせにくい。
As described above, in the daylighting device 100 according to the present embodiment, since the edge protection members 106 and 108 are attached to the panel 101 instead of the frame 102 by the double- sided adhesives 203 and 204, the mobility of the panel 101 is unlikely to be impaired. ..
例えば、採光装置１００が、枠１０２の前面（図１における手前側の面）や側面（図１における上下左右の面）に、採光装置１００を枠１０２に取り付けるための取り付け部材によって固定すると、取り付け部材が、枠１０２から突出する。
For example, when the lighting device 100 is fixed to the front surface (front surface in FIG. 1) or the side surfaces (upper, left, right surfaces in FIG. 1) of the frame 102 by a mounting member for mounting the lighting device 100 to the frame 102, the mounting is performed. The member projects from the frame 102.
このため、パネル１０１を移動させる際に、枠１０２から突出した取り付け部材が、枠１０２の周囲の部材と干渉し、パネル１０１の可動性を損なわせるおそれがある。これに対して、端部保護部材１０６，１０８を両面粘着剤２０３，２０４によって、枠１０２ではなくパネル１０１に貼り付けるため、採光装置１００の一部が枠１０２から突出することを抑制でき、パネル１０１の可動性の低下を抑制できる。
Therefore, when the panel 101 is moved, the mounting member protruding from the frame 102 may interfere with the members around the frame 102 and impair the mobility of the panel 101. On the other hand, since the end protection members 106 and 108 are attached to the panel 101 instead of the frame 102 by the double- sided adhesives 203 and 204, it is possible to prevent a part of the lighting device 100 from protruding from the frame 102, and It is possible to suppress a decrease in the mobility of 101.
また採光装置１００では、端部保護部材１０６のみがパネル１０１に貼り付けられ、採光装置１００とパネル１０１との接触箇所が限定され、パネル１０１への負荷が抑制されるため、採光装置１００とパネル１０１とを容易に着脱が可能となる。
Further, in the daylighting device 100, only the end protection member 106 is attached to the panel 101, the contact portion between the daylighting device 100 and the panel 101 is limited, and the load on the panel 101 is suppressed. 101 can be easily attached and detached.
また採光装置１００では、採光フィルム１０５が端部保護部材１０６によって支持されるため、採光装置１００をパネル１０１と同程度の大きさとしやすいため、複数個の採光装置１００をパネル１０１に敷き詰めなければいけない場合が少なくなる。このため、採光装置１００をパネル１０１に設置した場合においても、パネル１０１の外観や意匠性を保ちやすくなる。
Further, in the daylighting device 100, since the daylighting film 105 is supported by the end protection member 106, it is easy to make the daylighting device 100 as large as the panel 101. Therefore, a plurality of daylighting devices 100 must be spread over the panel 101. There are few cases. Therefore, even when the lighting device 100 is installed on the panel 101, the appearance and design of the panel 101 can be easily maintained.
また採光フィルム１０５に両面粘着剤２０３，２０４を直接貼り付けないため、採光フィルム１０５の熱収縮や熱膨張によって採光装置１００がパネル１０１から剥がれてしまう懸念をしなくてよい。採光フィルム１０５の熱収縮や熱膨張を考慮しなくてよいため、採光装置１００を所定の大きさ以上としやすくなる。
Further, since the double- sided adhesives 203 and 204 are not directly attached to the daylighting film 105, there is no need to worry that the daylighting device 100 may be peeled off from the panel 101 due to heat shrinkage or thermal expansion of the daylighting film 105. Since it is not necessary to consider the heat shrinkage and the thermal expansion of the daylighting film 105, it is easy to make the daylighting device 100 larger than a predetermined size.
採光フィルム１０５の熱収縮や熱膨張を考慮しなくてよいため、例えば採光装置１００の幅を１．８ｍ以上とすることが容易となる。
Since it is not necessary to consider the thermal contraction and thermal expansion of the daylighting film 105, it becomes easy to set the width of the daylighting device 100 to be 1.8 m or more, for example.
昼夜の温度差を３０℃とし、採光フィルム１０５の素材をポリエステルフィルム（以下、これをＰＥＴフィルムと呼んでもよい）とし、パネル１０１の素材をガラスとした場合、幅１．８ｍ当たりの採光フィルム１０５の熱収縮や熱膨張は１ｍｍを超え、パネル１０１との熱膨張や熱収縮の差も０．５ｍｍを超える。なおＰＥＴフィルムの熱膨張率２．０（１０－５／℃）であり、ガラスの熱膨張率の約２倍であるとしている。
When the temperature difference between day and night is 30° C., the material of the daylighting film 105 is a polyester film (hereinafter, this may be referred to as PET film), and the material of the panel 101 is glass, the daylighting film 105 per width of 1.8 m. The thermal contraction and the thermal expansion of the panel 101 exceed 1 mm, and the difference in the thermal expansion and the thermal contraction with the panel 101 also exceeds 0.5 mm. The coefficient of thermal expansion of the PET film is 2.0 (10 −5 /° C.), which is about twice the coefficient of thermal expansion of glass.
例えば採光フィルム１０５を直接パネル１０１に貼り付ける場合に採光フィルム１０５を薄くすると採光フィルム１０５の熱膨張や熱収縮によって、採光フィルム１０５がパネル１０１から剥がれたり採光フィルム１０５が撓んだりしてしまう。これに対して本願発明の採光装置で１００では採光フィルム１０５に両面粘着剤２０３，２０４を直接貼り付けないため、採光装置１００を所定の大きさ以上とした場合も採光フィルム１０５がパネル１０１から剥がれたり、採光フィルム１０５が歪んだりしにくい。
For example, when the daylighting film 105 is directly attached to the panel 101, if the daylighting film 105 is made thin, the daylighting film 105 may be peeled off from the panel 101 or the daylighting film 105 may be bent due to thermal expansion or contraction of the daylighting film 105. On the other hand, in the daylighting device 100 of the present invention, since the double- sided adhesives 203 and 204 are not directly attached to the daylighting film 105, the daylighting film 105 is peeled off from the panel 101 even when the daylighting device 100 has a predetermined size or more. It is difficult for the lighting film 105 to be distorted.
また採光装置１００の一部である端部保護部材１０６Ａのみで採光装置１００がパネル１０１に設置される位置が決められるため、採光装置１００は意図されたように容易にパネル１０１に設置されることができる。
Further, since the position where the daylighting device 100 is installed on the panel 101 is determined only by the end protection member 106A which is a part of the daylighting device 100, the daylighting device 100 can be easily installed on the panel 101 as intended. You can
なお端部保護部材１０８は端部保護部材１０６と同様にパネル１０１に貼り付ける側と室内側とで分離できてもよく、先にパネル１０１に貼り付ける側を貼り付けてもよい。このため分離できる場合は採光フィルム１０５が端部保護部材１０６Ａに支持される際、端部保護部材１０８に採光フィルム１０５を挿入するために採光フィルム１０５が曲げられる必要がなくなる。
Like the end protection member 106, the end protection member 108 may be separated into the side to be attached to the panel 101 and the indoor side, or the side to be attached to the panel 101 may be attached first. For this reason, when the daylighting film 105 is separable, it is not necessary to bend the daylighting film 105 to insert the daylighting film 105 into the end part protection member 108 when the daylighting film 105 is supported by the end part protection member 106A.
端部保護部材１０８を分離可能とする場合、端部保護部材１０６と同様に端部保護部材１０８に支持部として突部を設け、採光フィルム１０５の設置される際の鉛直方向の下側に突部と対応する孔を設けてもよい。この場合、端部保護部材１０６に加えて端部保護部材１０８でも採光フィルム１０５を鉛直方向の下側で支持ため、端部保護部材１０８に突部を設けない場合と比較して、端部保護部材１０６，１０８が採光フィルム１０５をしっかり支持することができる。
When the end protection member 108 is separable, a projection is provided as a support portion on the end protection member 108 as with the end protection member 106, and the projection is provided on the lower side in the vertical direction when the daylighting film 105 is installed. You may provide the hole corresponding to a part. In this case, in addition to the end protection member 106, the end protection member 108 also supports the daylighting film 105 on the lower side in the vertical direction, so that the end protection member 108 is protected from the end portion as compared with the case where no projection is provided. The members 106 and 108 can firmly support the daylighting film 105.
なお端部保護部材１０８に支持部を設ける場合は端部保護部材１０６に支持部を設けなくてもよい。これは、端部保護部材１０８に設けられた支持部によって採光フィルム１０５の幅方向の動きを制限でき、端部保護部材１０６によって採光フィルム１０５の厚さ方向の動きを制限できればよいためである。端部保護部材１０８に支持部を設け、端部保護部材１０６に支持部を設けない場合も端部保護部材１０８に支持部を設けず、端部保護部材１０６に支持部を設けた場合同様に採光フィルムを支持することができる。
When the support portion is provided on the end protection member 108, the support portion need not be provided on the end protection member 106. This is because the support portion provided on the end protection member 108 can limit the movement of the daylighting film 105 in the width direction, and the end protection member 106 can limit the movement of the daylighting film 105 in the thickness direction. Even when the end protection member 108 is provided with the support portion and the end protection member 106 is not provided with the support portion, the end protection member 108 is not provided with the support portion and the end protection member 106 is provided with the support portion. A daylighting film can be supported.
端部保護部材１０６，１０８と採光フィルム１０５の端部との間には空隙部２１３，２１４が設けられており、採光フィルム１０５が膨張した際にも、採光フィルム１０５がゆがまないようにすることができる。
Voids 213 and 214 are provided between the end protection members 106 and 108 and the ends of the daylighting film 105, so that the daylighting film 105 is not distorted even when the daylighting film 105 expands. You can
具体的には空隙部２１３は採光フィルム１０５の上端部と、端部保護部材１０６との間に形成され、空隙部２１４は採光フィルム１０５の下端部と、端部保護部材１０８との間に形成される。
Specifically, the void portion 213 is formed between the upper end portion of the daylighting film 105 and the end portion protection member 106, and the void portion 214 is formed between the lower end portion of the daylighting film 105 and the end portion protection member 108. To be done.
また端部保護部材１０６Ａの内面と、端部保護部材１０６Ｂの内面との間の距離は、採光フィルム１０５の厚み寸法よりも大きい。また突部２０２から端部保護部材１０６Ｂの内側下面（フィルム厚さ方向に延出する部分の下面）までの距離は、採光フィルム１０５の上端から孔１０７までの距離よりも大きい。
The distance between the inner surface of the end protection member 106A and the inner surface of the end protection member 106B is larger than the thickness dimension of the daylighting film 105. Further, the distance from the protrusion 202 to the inner lower surface of the end protection member 106B (the lower surface of the portion extending in the film thickness direction) is larger than the distance from the upper end of the daylighting film 105 to the hole 107.
なおゴムなどの弾性を有する素材からなる弾性シーリング材２０１がパネル１０１と枠１０２との隙間を埋めていてもよい。また図示していないが、引き違い窓などのように枠１０２の外側には外枠が設けられていてもよく、枠１０２と外枠との間にパネル１０１を開閉するための機構が設けられていてもよい。
An elastic sealing material 201 made of an elastic material such as rubber may fill the gap between the panel 101 and the frame 102. Although not shown, an outer frame may be provided outside the frame 102 such as a sliding window, and a mechanism for opening and closing the panel 101 is provided between the frame 102 and the outer frame. May be.
端部保護部材１０６，１０８の厚さと両面粘着剤２０３，２０４の厚さとの和ｔ２は、パネル１０１の外側から、パネル１０１の全周に設けられパネル１０１を支えるパネルの開閉のための枠１０２の外側までの厚さｔ１よりも小さい。なお例えば厚さｔ１は５ｍｍ～１０ｍｍ程度とする。このため、採光装置１００は引き違い窓などに適用された場合も枠１０２の可動性を確保することが可能となる。
The sum t2 of the thicknesses of the end protection members 106 and 108 and the thicknesses of the double- sided adhesives 203 and 204 is the frame 102 for opening and closing the panel which is provided on the entire circumference of the panel 101 from the outside of the panel 101 and supports the panel 101. Is smaller than the thickness t1 to the outside. The thickness t1 is, for example, about 5 mm to 10 mm. Therefore, the lighting device 100 can ensure the movability of the frame 102 even when applied to a sliding window or the like.
両面粘着剤２０３は、端部保護部材１０６の端部保護部材１０６がパネル１０１と対面する面の全面に付着している。同様に両面粘着剤２０４は、端部保護部材１０８の端部保護部材１０６がパネル１０１と対面する面の全面に付着している。なお本実施の形態においては、上述のように端部保護部材１０６によって採光フィルム１０５は支持されるため、端部保護部材１０８はなくてもよい。
The double-sided adhesive 203 is attached to the entire surface of the end protection member 106 facing the panel 101. Similarly, the double-sided pressure-sensitive adhesive 204 is attached to the entire surface of the end protection member 108 of the end protection member 108 facing the panel 101. In this embodiment, since the daylighting film 105 is supported by the end protection member 106 as described above, the end protection member 108 may be omitted.
端部保護部材１０８が設けられる場合は、採光フィルム１０５の上辺に設けられた端部保護部材１０６と対応するように採光フィルム１０５の下辺に設けられ、端部保護部材１０６が採光フィルム１０５を支持できなくなった場合に代わりに支持するようにする。なお端部保護部材１０６，１０８は採光フィルム１０５を支持するという観点から採光フィルム１０５と同じ幅程度であることが望ましく、孔１０７及び突部２０２は少なくとも両端と中央部に設けられることが望ましい。
When the edge protection member 108 is provided, it is provided on the lower side of the daylighting film 105 so as to correspond to the edge protection member 106 provided on the upper side of the daylighting film 105, and the edge part protection member 106 supports the daylighting film 105. If you can't do it, support it instead. The edge protection members 106 and 108 preferably have the same width as that of the daylighting film 105 from the viewpoint of supporting the daylighting film 105, and the holes 107 and the protrusions 202 are preferably provided at least at both ends and the center.
なお孔１０７及び突部２０２は、２０ｃｍ程度の所定の間隔ごとに設けられることがより望ましい。孔１０７及び突部２０２を所定の間隔ごとに設けることで、採光フィルム１０５に熱膨張や熱収縮が発生した際に採光フィルム１０５の熱膨張や熱収縮を等しく分散することができ、採光フィルム１０５の撓みを抑制することができる。
It is more desirable that the holes 107 and the protrusions 202 are provided at predetermined intervals of about 20 cm. By providing the holes 107 and the protrusions 202 at predetermined intervals, it is possible to evenly disperse the thermal expansion and contraction of the daylighting film 105 when the daylighting film 105 undergoes thermal expansion and contraction. Can be suppressed.
このように採光装置１００とパネル１０１とが対面する面の全面には両面粘着剤２０３，２０４を付着せずに、パネル１０１の端部に設けられた端部保護部材１０６，１０８がパネル１０１と対面する面のみに両面粘着剤２０３，２０４を付着することで、付着面積を低減させることができ、採光装置１００をパネル１０１から容易に剥がすことができる。
In this way, the double- sided adhesives 203 and 204 are not attached to the entire surfaces where the daylighting device 100 and the panel 101 face each other, and the end protection members 106 and 108 provided at the end portions of the panel 101 are connected to the panel 101. By attaching the double- sided adhesives 203 and 204 only to the facing surfaces, the attachment area can be reduced and the daylighting device 100 can be easily peeled off from the panel 101.
また上述の付着面積の低減により、パネル１０１から採光装置１００を剥がす際に両面粘着剤２０３，２０４の一部がパネル１０１に残りづらくすることができるためパネル１０１への負荷が少なくすることができる。
Further, due to the reduction of the adhesion area, it is possible to make it difficult for some of the double- sided adhesives 203 and 204 to remain on the panel 101 when the lighting device 100 is peeled off from the panel 101, so that the load on the panel 101 can be reduced. ..
また採光フィルム１０５は端部保護部材１０６に支持されるのみで固定されていないため、採光フィルム１０５と端部保護部材１０６との熱膨張率の差による影響を抑制することができる。このため、例えば、採光フィルム１０５が膨張や収縮した際に端部保護部材１０６へは影響が及ばず、採光フィルム１０５の影響で端部保護部材１０６が変形することはない。また採光フィルム１０５の影響で端部保護部材１０６が変形することはないため、端部保護部材１０６の変形による応力で両面粘着剤２０３が剥がれることがない。
Further, since the daylighting film 105 is supported only by the end protection member 106 but not fixed, it is possible to suppress the influence of the difference in the coefficient of thermal expansion between the daylighting film 105 and the end protection member 106. Therefore, for example, when the daylighting film 105 expands or contracts, the end protection member 106 is not affected, and the endlight protection film 106 does not deform due to the influence of the daylighting film 105. Further, since the edge protection member 106 is not deformed by the influence of the daylighting film 105, the double-sided adhesive 203 is not peeled off due to the stress due to the deformation of the edge protection member 106.
さらに両面粘着剤２０３は、粘着性を有する粘着材料２０５，２０７と剛性を有する基材２０６からなり、粘着材料２０５は、端部保護部材１０６と基材２０６とを付着し、粘着材料２０７は基材２０６とパネル１０１とを付着する。同様に両面粘着剤２０４は、粘着性を有する粘着材料２０８，２１０と剛性を有する基材２０９からなり、粘着材料２０８は、端部保護部材１０８と基材２０９とを付着し、粘着材料２１０は基材２０９とパネル１０１とを付着する。
Further, the double-sided adhesive 203 is composed of adhesive materials 205 and 207 having adhesiveness and a base material 206 having rigidity. The adhesive material 205 adheres the end protection member 106 and the base material 206, and the adhesive material 207 is a base material. The material 206 and the panel 101 are attached. Similarly, the double-sided pressure-sensitive adhesive 204 includes pressure-sensitive adhesive materials 208 and 210 and a rigid base material 209. The adhesive material 208 adheres the end protection member 108 and the base material 209, and the adhesive material 210 is The base material 209 and the panel 101 are attached.
両面粘着剤２０３，２０４においては、入射光１０３側（パネル１０１側）の粘着材料２０７，２１０の剥離強度及びせん断接着強度の少なくとも１つ（以下、これを粘着強度と呼んでもよい）が出射光１０４側（端部保護部材１０６，１０８側）の粘着材料２０５，２０８よりも低い。このため、採光装置１００をパネル１０１から簡単に剥がすことができ、かつ、パネル１０１から剥がされる際に採光装置１００は端部保護部材１０６，１０８と両面粘着剤２０３，２０４との付着を維持することができる。
In the double- sided adhesives 203 and 204, at least one of the peeling strength and the shear adhesive strength of the adhesive materials 207 and 210 on the incident light 103 side (panel 101 side) (hereinafter, this may be referred to as adhesive strength) is emitted light. It is lower than the pressure-sensitive adhesive materials 205 and 208 on the 104 side ( end protection members 106 and 108 side). Therefore, the lighting device 100 can be easily peeled off from the panel 101, and when the lighting device 100 is peeled off from the panel 101, the lighting device 100 maintains the adhesion between the end protection members 106 and 108 and the double- sided adhesives 203 and 204. be able to.
粘着材料２０５，２０８は、例えばアクリル系の粘着材料で、９０°剥離試験での評価結果として剥離強度が２Ｎ／ｃｍ以上、せん断接着強度が１Ｎ／ｃｍ２以上とする。また粘着材料２０７，２１０は、例えばアクリル系やシリコーン系の粘着材料で、９０°剥離試験での評価結果として剥離強度が２Ｎ／ｃｍ以下、せん断接着強度が１Ｎ／ｃｍ２以上とし、自己吸着性粘着剤などとする。
The adhesive materials 205 and 208 are, for example, acrylic adhesive materials, and have a peel strength of 2 N/cm or more and a shear adhesive strength of 1 N/cm 2 or more as an evaluation result in a 90° peel test. The adhesive materials 207 and 210 are, for example, acrylic or silicone adhesive materials, and have a peel strength of 2 N/cm or less and a shear adhesive strength of 1 N/cm 2 or more as a result of evaluation in a 90° peel test, and have self-adhesiveness. Use as an adhesive.
なお本実施の形態の両面粘着剤２０３，２０４には、粘着材料２０５，２０８と粘着材料２０７，２１０との間に両面粘着剤２０３，２０４の剛性を高くするために基材２０６，２０９が設けられている。両面粘着剤２０３，２０４の剛性は、基材２０６，２０９の厚さや基材２０６，２０９の材料を変更することで調節する。両面粘着剤２０３，２０４の剛性は、採光装置１００をパネル１０１から剥がしやすくするような所定の値以上とする。
The double- sided adhesives 203 and 204 of this embodiment are provided with base materials 206 and 209 between the adhesive materials 205 and 208 and the adhesive materials 207 and 210 in order to increase the rigidity of the double- sided adhesives 203 and 204. Has been. The rigidity of the double- sided adhesives 203 and 204 is adjusted by changing the thickness of the base materials 206 and 209 and the material of the base materials 206 and 209. The rigidity of the double- sided adhesives 203 and 204 is set to a predetermined value or more so that the lighting device 100 can be easily peeled off from the panel 101.
なお端部保護部材１０６が所定値以上の剛性であり、端部保護部材１０６が採光フィルム１０５の重量に耐え採光フィルム１０５を支持するのに十分な剛性を有する場合、粘着材料２０５と粘着材料２０７とを直接結合してもよい。
When the edge protection member 106 has a rigidity of a predetermined value or more and the edge protection member 106 has sufficient rigidity to support the weight of the daylighting film 105 and support the daylighting film 105, the adhesive material 205 and the adhesive material 207 are included. You may directly combine and.
例えば端部保護部材１０６を１ｃｍ幅、厚さ５０μｍのＰＥＴフィルムとしとした場合、端部保護部材１０６は採光フィルム１０５の重量に耐え、採光フィルム１０５を支持するのに十分な剛性を有するといえる。
For example, when the edge protection member 106 is a PET film having a width of 1 cm and a thickness of 50 μm, the edge protection member 106 can bear the weight of the daylighting film 105 and has sufficient rigidity to support the daylighting film 105. ..
なおここで剛性とは曲げ剛性を指し、曲げ剛性は曲げ剛性（ＥＩ）＝ヤング率（Ｅ）×断面二次モーメント（Ｉ）の式であらわされる物性値であり、ヤング率は材料に特有の値、断面二次モーメントは断面形状に依存する値である。断面が幅ｂ、厚さｈの対象物の場合、断面二次モーメントはＩ= ｂｈ３／１２で求められる。ＰＥＴフィルムのヤング率は材料によって多少異なるが、３～４ＧＰａというのが一般的な値である。
Here, the rigidity means bending rigidity, and the bending rigidity is a physical property value expressed by the formula of bending rigidity (EI)=Young's modulus (E)×second moment of area (I), and Young's modulus is peculiar to the material. The value and the moment of inertia of area are values that depend on the cross-sectional shape. In the case of an object whose cross section is width b and thickness h, the moment of inertia of area is calculated by I=bh 3 /12. Although the Young's modulus of the PET film is slightly different depending on the material, it is generally 3 to 4 GPa.
粘着材料２０５と粘着材料２０７とを直接結合した場合も採光装置１００からのパネル１０１の剥がしやすさは両面粘着剤２０３に基材２０６を設けられた場合と変わらない。なお、端部保護部材１０８に付着させる両面粘着剤２０４についても同様に基材２０９を設けずに粘着材料２０８と粘着材料２１０とを直接結合してもよい。
Even when the adhesive material 205 and the adhesive material 207 are directly bonded, the ease of peeling the panel 101 from the lighting device 100 is the same as when the base material 206 is provided on the double-sided adhesive 203. Regarding the double-sided pressure-sensitive adhesive 204 attached to the end protection member 108, the pressure-sensitive adhesive material 208 and the pressure-sensitive adhesive material 210 may be directly bonded without providing the base material 209.
なお、保護部材１０６等の構成は、図３（Ａ）（Ｂ）（Ｃ）に示す第１の実施の形態による別の採光装置の拡大図に示すようにしてもよい。図３（Ａ）に示すようにすべての突部２０２に採光フィルム１０５の厚さと同程度よりも厚さが少し厚く断面が矩形で、突部２０２の幅方向に延伸する切かけ部３０１を設けてもよい。
The configuration of the protection member 106 and the like may be as shown in an enlarged view of another lighting device according to the first embodiment shown in FIGS. 3(A), (B), and (C). As shown in FIG. 3A, all the protrusions 202 are provided with a notch 301 that is slightly thicker than the thickness of the daylighting film 105 and has a rectangular cross section and extends in the width direction of the protrusions 202. May be.
切かけ部３０１は採光フィルム１０５の厚さ方向の動きを制限するため、切かけ部３０１を設けない場合に比べ採光フィルム１０５のへ端部保護部材１０６の支持を強くし、採光フィルム１０５のぐらつきを押さえることができる。
Since the notch portion 301 restricts the movement of the daylighting film 105 in the thickness direction, the edge protection member 106 of the daylighting film 105 is more strongly supported than when the notch portion 301 is not provided, and the wobbling of the daylighting film 105 is prevented. Can be held down.
また図３（Ｂ）に示すようにすべての突部２０２に採光フィルム１０５の厚さと同程度よりも厚さが少し厚く断面が三角形で突部２０２の幅方向に延伸する切かけ部３０２を設けてもよい。
Further, as shown in FIG. 3B, all the projections 202 are provided with a cut portion 302 having a slightly thicker thickness than that of the daylighting film 105 and a triangular cross section and extending in the width direction of the projection 202. May be.
切かけ部３０２は採光フィルム１０５が自重で食い込めば食い込むほど、採光フィルム１０５の厚さ方向の動きを制限する。このため切かけ部３０１を設けた場合に比べて、より採光フィルム１０５のへ端部保護部材１０６の支持を強くし、採光フィルム１０５のぐらつきを押さえることができる。
The notch 302 limits the movement of the lighting film 105 in the thickness direction as the lighting film 105 bites under its own weight. Therefore, as compared with the case where the notch 301 is provided, the edge protection member 106 of the daylighting film 105 is more strongly supported, and the wobbling of the daylighting film 105 can be suppressed.
また本実施の形態の採光装置１００においては図３（Ｃ）に示す孔１０７を設けない採光フィルム３０５のようにすることもできる。この場合、採光フィルム３０５の上辺に設置する端部保護部材３０３の内側に採光フィルム３０５を支持する支持部としてクリップ部３０４が設けられる必要がある。例えばクリップ部３０４は、１つ以上であればよく、例えば幅方向に３つ設けられる。
In addition, in the daylighting device 100 of the present embodiment, a daylighting film 305 without the hole 107 shown in FIG. 3C may be used. In this case, the clip portion 304 needs to be provided as a support portion that supports the daylighting film 305 inside the end protection member 303 installed on the upper side of the daylighting film 305. For example, the number of the clip portions 304 may be one or more, and for example, three clip portions 304 are provided in the width direction.
クリップ部３０４は、端部保護部材３０３のパネル側の内面に、端部保護部材３０３の内面に対向する面（対向面）に向かって突出して設けられ、採光フィルム１０５の厚さ方向に弾性変形可能である。
The clip portion 304 is provided on the panel-side inner surface of the end protection member 303 so as to project toward the surface (opposing surface) facing the inner surface of the end protection member 303, and elastically deforms in the thickness direction of the daylighting film 105. It is possible.
クリップ部３０４は、端部保護部材３０３の対向面３０３Ｂに採光フィルム１０５を採光フィルム１０５の厚さ方向に押圧することで採光フィルムを支持し鉛直方向下向きに採光フィルム１０５が落下するのを防ぐ。採光装置１００にクリップ部３０４が設けられた場合も、採光装置１００に突部２０２が設けられている場合と同様の効果が得られる。
The clip portion 304 supports the daylighting film 105 by pressing the daylighting film 105 in the thickness direction of the daylighting film 105 against the facing surface 303B of the end protection member 303, and prevents the daylighting film 105 from dropping vertically downward. Even when the clip part 304 is provided in the daylighting device 100, the same effect as when the projecting part 202 is provided in the daylighting device 100 is obtained.
またクリップ部３０４が設けられる場合は、採光装置１００が設置される際に端部保護部材３０３を分離することなく採光フィルム１０５が設置できるため、端部保護部材３０３は分離可能でなくてよい。
Further, when the clip portion 304 is provided, since the lighting film 105 can be installed without separating the end protection member 303 when the lighting device 100 is installed, the end protection member 303 does not have to be separable.
なお本実施の形態の採光装置１００においては、端部保護部材１０６，１０８をパネル１０１に固定しなくてもよく、枠１０２の可動性を確保できる場合であれば、端部保護部材１０６，１０８を枠１０２の鉛直方向に設けられている面に固定してもよい。端部保護部材１０６，１０８を枠１０２の鉛直方向に設けられている面に固定しても枠１０２の可動性を確保できる場合の一例としては、引き違い窓ではなく外倒し窓などに採光装置１００を適用する場合が挙げられる。
In the daylighting device 100 of the present embodiment, the end protection members 106 and 108 do not have to be fixed to the panel 101, and if the movability of the frame 102 can be ensured, the end protection members 106 and 108 are provided. May be fixed to the surface of the frame 102 provided in the vertical direction. As an example of the case where the movability of the frame 102 can be ensured even if the end protection members 106 and 108 are fixed to the surface provided in the vertical direction of the frame 102, a daylighting device is used not on the sliding window but on the outside window or the like. The case where 100 is applied is mentioned.
［第２の実施の形態］
第１の実施の形態においては、採光フィルム１０５，３０５の上辺に設けられた端部保護部材１０６，３０３に設けられた支持部で採光フィルム１０５を主に支持する場合について述べた。これに対して本実施の形態では、主に、採光フィルム４０５の下辺に設けられた端部保護部材４０２によって採光フィルム４０５を主に支持している点が第１の実施の形態と異なる。 [Second Embodiment]
In the first embodiment, the case where thedaylighting film 105 is mainly supported by the supporting portions provided on the end protection members 106 and 303 provided on the upper sides of the daylighting films 105 and 305 has been described. On the other hand, the present embodiment differs from the first embodiment mainly in that the daylighting film 405 is mainly supported by the end protection member 402 provided on the lower side of the daylighting film 405.
第１の実施の形態においては、採光フィルム１０５，３０５の上辺に設けられた端部保護部材１０６，３０３に設けられた支持部で採光フィルム１０５を主に支持する場合について述べた。これに対して本実施の形態では、主に、採光フィルム４０５の下辺に設けられた端部保護部材４０２によって採光フィルム４０５を主に支持している点が第１の実施の形態と異なる。 [Second Embodiment]
In the first embodiment, the case where the
図４は、本実施の形態における採光装置４００を示す。また図５は、図４のＶ－Ｖの概略断面図である。図４、図５に示すように本実施の形態における採光装置４００においては、採光フィルム４０５の下辺に設けられた端部保護部材４０２によって採光フィルム４０５を主に支持している。
FIG. 4 shows a daylighting device 400 according to the present embodiment. FIG. 5 is a schematic sectional view taken along line VV of FIG. As shown in FIGS. 4 and 5, in the daylighting device 400 of the present embodiment, the daylighting film 405 is mainly supported by the end protection member 402 provided on the lower side of the daylighting film 405.
図４に示すように採光装置４００は、パネル１０１から入光する入射光１０３の角度を変えて出射光１０４として出光する採光フィルム４０５を備える。室外からの入射光１０３は、パネル１０１の室内側に設置された採光装置４００によってされた室内への出射光１０４として出射される。
As shown in FIG. 4, the daylighting device 400 includes a daylighting film 405 that changes the angle of the incident light 103 entering from the panel 101 and emits it as outgoing light 104. The incident light 103 from the outside is emitted as the emitted light 104 to the room by the lighting device 400 installed on the indoor side of the panel 101.
採光装置４００は、採光フィルム４０５の端部の全周を覆って保護する端部保護部材４０１，４０２，４０３，４０４を備える。また採光装置４００は、端部保護部材４０１，４０２に取り付けられ、端部保護部材４０１，４０２をパネル１０１に貼り付ける両面粘着剤５０１，５０２を備える。図示していないが端部保護部材４０３，４０４も同様に両面粘着剤によってパネル１０１に貼り付けられている。
The lighting device 400 includes end protection members 401, 402, 403, and 404 that cover and protect the entire circumference of the end of the lighting film 405. Further, the daylighting device 400 includes double- sided adhesives 501 and 502 attached to the end protection members 401 and 402 and attaching the end protection members 401 and 402 to the panel 101. Although not shown, the end protection members 403 and 404 are similarly attached to the panel 101 with a double-sided adhesive.
端部保護部材４０１，４０２，４０３，４０４をパネル１０１に貼り付ける両面粘着剤５０１，５０２などは、第１の実施の形態の両面粘着剤２０３，２０４と同様とするためここでは説明を省略する。
Since the double- sided adhesives 501, 502 and the like for attaching the end protection members 401, 402, 403, 404 to the panel 101 are the same as the double- sided adhesives 203, 204 of the first embodiment, description thereof will be omitted here. ..
また端部保護部材４０１，４０２の厚さと両面粘着剤５０１，５０２の厚さとの和ｔ３を厚さｔ１よりも小さくことで採光装置４００は引き違い窓などに適用することができる。
Further, by making the sum t3 of the thickness of the end protection members 401 and 402 and the thickness of the double- sided adhesives 501 and 502 smaller than the thickness t1, the lighting device 400 can be applied to a sliding window or the like.
端部保護部材４０１，４０３，４０４と採光フィルム４０５の端部との間には空隙部が設けられており、採光フィルム４０５が膨張した際にも、採光フィルム１０５がゆがまないようにすることができる。具体的には、端部保護部材４０１と端部保護部材４０２のそれぞれの内面の間の寸法は、採光フィルム４０５の鉛直方向における寸法よりも大きい。
A gap is provided between the end protection members 401, 403, 404 and the end of the daylighting film 405 so that the daylighting film 105 is not distorted even when the daylighting film 405 expands. it can. Specifically, the dimension between the inner surfaces of the end protection member 401 and the end protection member 402 is larger than the dimension of the daylighting film 405 in the vertical direction.

Further, in the lighting device 600, the corner protection members 605, 606, 607, 608 cover a part of the outer circumference of the end protection members 601, 602, 603, 604.
図６に示すように採光装置６００は、パネル１０１から入光する入射光１０３の角度を変えて出射光１０４として出光する採光フィルム４０５を備える。室外からの入射光１０３は、パネル１０１の室内側に設置された採光装置６００によってされた室内への出射光１０４として出射される。
As shown in FIG. 6, the daylighting device 600 includes a daylighting film 405 that changes the angle of the incident light 103 entering from the panel 101 and emits it as outgoing light 104. The incident light 103 from the outside is emitted as the emitted light 104 to the room by the lighting device 600 installed on the indoor side of the panel 101.
採光装置６００は、採光フィルム４０５の端部を覆って保護する端部保護部材６０１，６０２，６０３，６０４を備える。また採光装置６００は、端部保護部材６０１，６０２に取り付けられ、端部保護部材６０１，６０２をパネル１０１に貼り付ける両面粘着剤７０１，７０２を備える。図示していないが端部保護部材６０３，６０４も同様に両面粘着剤によってパネル１０１に貼り付けられている。
The daylighting device 600 includes end protection members 601, 602, 603, 604 that cover and protect the ends of the daylighting film 405. Further, the lighting device 600 includes double- sided adhesives 701 and 702 that are attached to the end protection members 601 and 602 and that attach the end protection members 601 and 602 to the panel 101. Although not shown, the end protection members 603 and 604 are similarly attached to the panel 101 with a double-sided adhesive.
採光装置６００は、端部保護部材６０１，６０２，６０３，６０４のさらに外周の採光フィルム４０５の隅部を覆って保護する隅部保護部材６０５，６０６，６０７，６０８を備える。また採光装置６００は、隅部保護部材６０６，６０８に取り付けられ、隅部保護部材６０６，６０８をパネル１０１に貼り付ける両面粘着剤７０３，７０４を備える。図示していないが隅部保護部材６０５，６０７も同様に両面粘着剤によってパネル１０１に貼り付けられている。
The daylighting device 600 includes corner protection members 605, 606, 607, 608 that cover and protect the corners of the daylighting film 405 on the outer periphery of the end protection members 601, 602, 603, 604. Further, the lighting device 600 includes double- sided adhesives 703 and 704 attached to the corner protection members 606 and 608 and attaching the corner protection members 606 and 608 to the panel 101. Although not shown, the corner protection members 605 and 607 are similarly attached to the panel 101 with a double-sided adhesive.
端部保護部材６０１，６０２，６０３，６０４及び隅部保護部材６０５，６０６，６０７，６０８をパネル１０１に貼り付ける両面粘着剤７０１，７０２，７０３，７０４などは、第１の実施の形態の両面粘着剤２０３，２０４と同様とし、ここでは説明を省略する。
The double-sided pressure- sensitive adhesives 701, 702, 703, 704 for attaching the edge protection members 601, 602, 603, 604 and the corner protection members 605, 606, 607, 608 to the panel 101 are the double-sided adhesives of the first embodiment. It is similar to the adhesives 203 and 204, and the description thereof is omitted here.
なお両面粘着剤７０３，７０４などのパネル１０１との粘着強度は、両面粘着剤７０１，７０２などのパネル１０１との粘着強度よりも強いことが望ましい。また両面粘着剤７０１，７０２などは採光装置６００をパネル１０１に着脱可能とする観点から自己吸着性粘着剤であることが望ましいが、両面粘着剤７０３，７０４などはパネル１０１との粘着面積が少ないため自己吸着性粘着剤でなくてもよい。
The adhesive strength of the double- sided adhesive 703, 704 or the like with the panel 101 is preferably stronger than the adhesive strength of the double- sided adhesive 701, 702 or the like with the panel 101. Further, the double- sided adhesives 701, 702 and the like are preferably self-adhesive adhesives from the viewpoint that the daylighting device 600 can be attached to and detached from the panel 101, but the double- sided adhesives 703, 704, etc. have a small adhesive area with the panel 101. Therefore, it does not need to be a self-adhesive adhesive.
言い換えると両面粘着剤７０１，７０２などがパネル１０１から剥がれるまでの時間（以下、これを故障モードと呼んでもよい）と両面粘着剤７０３，７０４など故障モードを変えることが望ましい。
In other words, it is desirable to change the time until the double- sided adhesive 701, 702 or the like is peeled from the panel 101 (hereinafter, this may be referred to as a failure mode) and the failure mode such as the double- sided adhesive 703, 704.
例えば両面粘着剤７０２と両面粘着剤７０４との故障モードが異なれば、両面粘着剤７０２が剥がれ端部保護部材６０２が採光フィルム４０５を支持できなくなってしまっても、両面粘着剤７０４によって粘着された隅部保護部材６０８が採光フィルム４０５を支持するため、採光フィルム４０５は落下しない。
For example, if the failure modes of the double-sided adhesive 702 and the double-sided adhesive 704 are different, even if the double-sided adhesive 702 is peeled off and the edge protection member 602 cannot support the daylighting film 405, the double-sided adhesive 704 is applied. Since the corner protection member 608 supports the daylighting film 405, the daylighting film 405 does not fall.
このように例えば両面粘着剤７０２と両面粘着剤７０４との故障モードとを変えることで、採光フィルム４０５の落下を未然に防ぐことができる。また採光フィルム４０５が落下せずに両面粘着剤７０２が剥がれている場合、少なくとも両面粘着剤７０２を交換しなければならない事がわかり、採光装置６００の交換時期の目安を使用者が知ることができる。
By thus changing the failure mode of the double-sided adhesive 702 and the double-sided adhesive 704, for example, the fall of the daylighting film 405 can be prevented. Moreover, when the double-sided adhesive 702 is peeled off without dropping the daylighting film 405, it is understood that at least the double-sided adhesive 702 must be replaced, and the user can know the standard of the replacement time of the daylighting device 600. ..
また端部保護部材６０１，６０３，６０４と採光フィルム４０５の端部との間には空隙部が設けられており、採光フィルム４０５が膨張した際にも、採光フィルム１０５がゆがまないようにすることができる。なお端部保護部材４０２は採光フィルム４０５を支持するため、端部保護部材６０２と採光フィルム４０５の端部との間には空隙部が設けられない。
In addition, a gap is provided between the end protection members 601, 603, 604 and the end of the daylighting film 405 so that the daylighting film 105 is not distorted even when the daylighting film 405 expands. You can Since the edge protection member 402 supports the daylighting film 405, no space is provided between the edge protection member 602 and the edge of the daylighting film 405.
また採光装置６００を設置した状態でパネル１０１の外観を保つために、端部保護部材６０１，６０２，６０３，６０４及び隅部保護部材６０５，６０６，６０７，６０８は採光フィルム４０５の外周を覆うようにすることが好ましい。またこの場合は採光フィルム４０５のそれぞれの辺において、隅部保護部材６０５，６０６，６０７，６０８は端部保護部材６０１，６０２，６０３，６０４の一部を覆うようにする。
Further, in order to maintain the appearance of the panel 101 with the lighting device 600 installed, the end protection members 601, 602, 603, 604 and the corner protection members 605, 606, 607, 608 cover the outer circumference of the lighting film 405. Is preferred. Further, in this case, the corner protection members 605, 606, 607, 608 are arranged to cover a part of the end protection members 601, 602, 603, 604 on each side of the daylighting film 405.
また端部保護部材６０１，６０２の厚さと両面粘着剤７０１，７０２の厚さとの和ｔ４は、隅部保護部材６０６，６０８の厚さと両面粘着剤７０３，７０４の厚さとの和ｔ５より小さい。
Further, the sum t4 of the thickness of the edge protection members 601 and 602 and the thickness of the double- sided adhesives 701 and 702 is smaller than the sum t5 of the thicknesses of the corner protection members 606 and 608 and the double- sided adhesives 703 and 704.
和ｔ４を和ｔ５より小さくすることで隅部保護部材６０５，６０６，６０７，６０８は端部保護部材６０１，６０２，６０３，６０４の一部を覆うようにすることができる。厚さｔ１より和ｔ５を小さくすることで採光装置４００は引き違い窓などに適用することができる。
By making the sum t4 smaller than the sum t5, the corner protection members 605, 606, 607, 608 can cover a part of the end protection members 601, 602, 603, 604. By making the sum t5 smaller than the thickness t1, the lighting device 400 can be applied to a sliding window or the like.
