Description

【０００１】
【発明の属する技術分野】
本発明は、窓ガラスの内側（内気側）又は窓ガラスの内側（内気側）と外側（外気側）との両側に取り付けて結露を防止する窓ガラスの結露防止構造に関するものである。
【０００２】
【従来の技術】
従来、窓ガラスの結露防止構造としては、例えば、特開平６−２１０８０４号公報に記載のものが知られている。
【０００３】
【発明が解決しようとする課題】
この特開平６−２１０８０４号公報に記載の結露防止構造は、ガラス繊維や不織布等の基材に吸水性ポリマーを重合固着させて構成の結露防止シートを窓ガラスに取り付け、吸水性ポリマーにより水や水蒸気を吸収するようにしたものである。
【０００４】
ところで、この結露防止用シートを透明・非透明の窓ガラスに取り付けた場合には、窓ガラスが遮蔽状態となって室内を暗くして雰囲気を損ない、外観体裁上においても好ましい状態ではない。
【０００５】
又、この結露防止用シートは、結露した水分を吸水性ポリマーによって吸収するに止まり、結露自体の発生（外気と内気との温度差）を防止するものではない。
【０００６】
本発明は、このような従来における吸水性ポリマーを利用した結露防止技術の問題点を解決するためになされたもので、その目的とするところは、透明性において窓ガラスと一体感を有して窓ガラスの本来的機能を損なうことなく、結露自体の発生を防止することができる窓ガラスの結露防止構造を提供することにある。

【００１１】
【発明の実施の形態】
本発明の実施の形態について図面を参照し、その作用と共に説明する。
【００１２】
本発明に係る窓ガラスの結露防止構造は、窓ガラスの内側（内気側）又は内側（内気側）と外側（外気側）の両側に結露防止パネル部材を取り付けて、外気が室内に入るのを遮断し、外気と内気との温度差（１０〜１５℃）から生じる結露を防止するものであって、図１は本発明に係る結露防止構造の一例での窓ガラス内側から見た一部省略の正面図、図２は一部を省略して示す図１の部分拡大図、図３は図１の３−３線に沿った部分拡大断面図、図４は図１の４−４線に沿った部分拡大断面図、図５は結露防止パネル部材の一例を示す一部省略の正面図、図６は図５の６−６線に沿った部分拡大断面図、図７は図５の７−７線に沿った部分拡大断面図、図８は両面粘着テープの一例を示す一部省略の概略平面図、図９は図８の９−９線に沿った拡大断面図、図１０は両面粘着テープの他例を示す一部省略の概略平面図、図１１は図１０の１１−１１線に沿った拡大断面図、図１２は本発明に係る窓ガラスの結露防止構造の他例を示す一部省略の概略正面図で、窓ガラス内側の結露防止パネル部材は図面の表示を簡潔にする目的で図示を省略してある。図１３は本発明に係る窓ガラスの結露防止構造の他例を示す一部省略の部分拡大断面、図１４は本発明に係る窓ガラスの結露防止構造において用いられる結露防止パネル部材の更なる他例を示す一部省略の部分平面図、図１５は図１４の部分拡大断面図である。
【００１３】
図１において、窓枠を省略して示す窓ガラス２０の内側（内気側）面の周囲に両面粘着テープを介して結露防止パネル部材が取り付けられている。
【００１４】
結露防止パネル部材３０は透明性・耐候性・耐熱性に優れ、燃えても自消性を有する等の特性を持ったポリカーボネート材から成る板状体であって、取り付けられる窓ガラス２０の大きさよりもやや小さい相似形を有している。
【００１５】
この結露防止パネル部材３０は、その相対向するパネル面部３１、３２間が、適宜数の仕切部３３を介して一定方向に等間隔で中空部３４が形成され、かつ各中空部の両端開口部が熱シール等により密閉シール部３５とされて、各中空部３４内の空気が動かないようにされている。
【００１６】
このように構成された結露防止パネル部材３０は、それ自体で冷気域を小さくして結露を防止する機能がある。
【００１７】
即ち、外気と接する建築物の窓ガラス側や壁面側等が寒く感じることはそこに冷気域があるからであって、結露防止パネル部材３０は、このような冷気域を小さくする効果があり、冷気域が小さくなるということは、冷たい外気が室内に入るのを遮断して内外気の温度差を小さくすることであって、これにより結露が防止されることになる。
【００１８】
冷気域は、結露防止パネル部材３０の全体の厚みＤが厚ければ厚い程、又パネル面部３１、３２の厚みｄが厚ければ厚い程、各中空部３４内の空気が動かないため、冷気域は小さくなって結露防止効果は顕著となる。
【００１９】
因みに、結露防止パネル部材３０は、その全体の厚さＤが３〜９mm、パネル面部３１、３２の厚さｄが０．３〜０．５mmのものが好ましい。
【００２０】
結露防止パネル部材３０を取り付けている両面粘着テープ４０は、図８から図１１に例示されているように、耐候性に優れ、かつ引っ張った場合に千切れることなく容易に伸長するゴム製基材４１の両面に粘着剤層４２とポリエステル等の樹脂材から成るメッシュ状剥離補助部材４３及び剥離紙４４が積層加工され、適宜の厚さを有して構成されている。
【００２１】
そして、両面粘着テープ４０は、その一方の粘着剤層４２がメッシュ状剥離補助部材４３を介して結露防止パネル部材３０の周縁（四辺）にそれぞれ分離し、かつ各隅部においては、縦横の両面粘着テープ４０の各端部が当接して恰も一体的に粘着されたような態様をもって粘着されるとともに、図１及び図２に示されているように、各縦横それぞれの両面粘着テープ４０におけるゴム製基材４１だけが結露防止パネル部材３０のパネル面部３１（３２）よりも僅かに外側に出た状態をもって取り付けられ、これらの出ているゴム製基材４１の端部４１ａが、後述する結露防止バネル部材３０を窓ガラス２０より剥がす際の摘み部分となっている。
【００２２】
次いで、窓ガラス２０の内側（内気側）に、結露防止パネル部材３０が両面粘着テープ４０における他方の粘着剤層４２とメッシュ状剥離補助部材４３を介し、かつ窓ガラス面と結露防止パネル部材３０のパネル面部３２との間に空間部５０を形成して粘着密閉される。
【００２３】
この窓ガラス２０への粘着取り付けにおいて、結露防止パネル部材３０はポリカーボネイト製であって、伸縮が小さく、寸法安定性があるが、さらなる安定性の観点から、伸縮により結露防止パネル部材３０が窓ガラス２０から外れないようにするため、窓ガラス２０の周囲に遊び幅２１をとって取り付け施工される。
【００２４】
窓ガラス２０の内側（内気側）に結露防止パネル部材３０が取り付けられた状態において、外気は結露防止パネル部材３０における各中空部３４内の動かない空気層と、窓ガラス２０と結露防止パネル部材３０との空間部５０内の動かない空気層とにより遮断されて、室内には伝わらず、冷気域が小さくなって（外気と内気との温度差が小さくなる）結露が防止される。
【００２５】
結露防止パネル部材３０を窓ガラス２０より剥がす必要が生じた場合には、各両面粘着テープ４０におけるゴム製基材４１の端部４１ａを持って外方に引っ張れば、ゴム製基材４１が容易に伸長して、テープ幅が次第に狭くなり、かつ結露防止パネル部材３０及び窓ガラス２０との粘着面は、各メッシュ状剥離補助部材４３の網目から出ている粘着剤をもって粘着されていて粘着面積は小さくなっているから、メッシュ状剥離補助部材４３の作用により窓ガラス２０から結露防止パネル部材３０を容易に剥がすことができる。
【００２６】
両面粘着テープは、図８及び図９に示された両面粘着テープ４０に代えて図１０及び図１１に示された相間剥離テープとして構成された両面粘着テープ６０を用いることもできる。
【００２７】
両面粘着テープ６０は、一対のテープ体６１により相間剥離用のメッシュ状剥離補助部材６６がサンドイッチ状に挟まれ、その一方の端部６６ａが一対のテープ体６１の端よりもやや突出させて構成されている。
【００２８】
一対のテープ体６１は、ゴム製基材６２の両面に粘着剤層６３が設けられ、それぞれ外側に向いた粘着剤層６３上にはメッシュ状剥離補助部材６４と剥離紙６５が積層されて形成され、内側に向いたそれぞれの粘着剤層６３が相間剥離用のメッシュ状剥離補助部材６６の両面に粘着されて相間剥離の両面粘着テープ６０とされている。
【００２９】
この両面粘着テープ６０による結露防止パネル部材３０の取り付けは、特に図示しないが、一方のテープ体６１における粘着剤層６３が前記両面粘着テープ４０による場合と同様にして結露防止パネル部材３０の周囲に粘着され、次いで、他方のテープ体６１における粘着剤層６３が窓ガラス２０の内側（内気側）に空間部５０を形成して粘着密閉される。
【００３０】
結露防止パネル部材３０を窓ガラス２０より剥がす必要が生じた場合には、各両面粘着テープ６０における相間剥離用のメッシュ状剥離補助部材６６の端部６６ａだけを持って外方に引っ張れば、一対のテープ体６１は腹割れ状態となって窓ガラス２０から結露防止パネル部材３０は分離される。しかる後、窓ガラス２０と結露防止パネル部材３０に粘着しているそれぞれのテープ体６１を除去すればよい。
【００３１】
図１２及び図１３は、本発明に係る窓ガラスの結露防止構造の他例であって、本例は、窓ガラスの内側（内気側）と外側（外気側）との両面に結露防止パネル部材がそれぞれ粘着されることにより、特に寒さの強い寒冷地において、高い結露防止効果が得られるものである。
【００３２】
図１２は、窓ガラス２０の内側の結露防止パネル部材３０は図面の表示を簡潔にする目的で図示を省略してある。
【００３３】
この図１２において、窓ガラス２０の外側（外気側）には結露防止パネル部材７０が両面粘着テープ４０（又は両面粘着テープ６０）を介し、かつ空間部５０を有して粘着密閉されている。
【００３４】
結露防止パネル部材７０は、ポリカーボネイト材から成る柔らかなフィルム状であって、構成上においては、前記板状の結露防止パネル部材３０と同じであり、ただ硬い板状体か、柔らかなフィルム状体かの相違のみである。
【００３５】
よって、構成についての説明は省略する。又、この結露防止パネル部材７０の両面粘着テープ４０（又は両面粘着テープ６０）による窓ガラス２０の外側（外気側）への取り付け、又は取り外しは前記結露防止パネル部材３０による場合と同じであるため、その詳細な説明は省略する。
【００３６】
ただ、窓ガラス２０の外側（外気側）に取り付けられる結露防止パネル部材が、板状体でなくフィルム状の結露防止パネル部材７０とされているのは、外部の強風等で飛ばされたとしても、板状体とは異なって危険ではないからである。
【００３７】
結露防止パネル部材７０は、前記のように窓ガラス２０の外側（外気側）の四辺に空間部５０を形成して粘着されるが、更に外部の強風等で飛ばされないようにするため、図１２に概略的に示されているように、結露防止パネル部材７０の一方の端７０ａは窓枠２２と構造物８０の端面とで内側（内気側）に挟み込まれて取り付けられている。
【００３８】
図１４及び図１５は、本発明に係る窓ガラスの結露防止構造において用いられる結露防止パネル部材の更なる他例を示したもので、この結露防止パネル部材８０は、全体がポリエチレン等の透明樹脂材から成り、表裏２枚のシート８１、８２と該シート８１、８２間に挟まれ高周波シールされて空気が密閉された気泡状部８４が規則的に又は不規則的に形成された中間シート８３から構成の空気を含んだ樹脂製気泡シート状体であって、シート８１、８２の表面には特に図示しないが、梨地模様、レース模様等の意匠がエンボス加工により施されている。
【００３９】
この結露防止パネル部材８０は、特に図示しないが、前記結露防止パネル部材３０、７０と同様にして、窓ガラス２０の内側（内気側）に、又は内側（内気側）と外側（外気側）との両側に前記同様にして、両面粘着テープ４０、６０を介し、かつ窓ガラス２０との間に空間部５０を設けて粘着密閉して取り付けられ、内側（内気側）又は内外両側の結露防止パネル部材８０における気泡状部８４内の動かない空気層と、内外それぞれの結露防止パネル部材８０と窓ガラス２０との空間部５０内の動かない空気層とにより外気は遮断されて、室内には伝わらず、冷気域が小さくなって（外気と内気との温度差が小さくなる）結露が防止される。
【００４０】
なお、梨地模様やレース模様等の意匠がエンボス加工さた本結露防止パネル部材８０によれば、室内雰囲気を高め得る。
【００４１】
【発明の効果】
しかして本発明によれば、従来のよな室内を暗くして雰囲気を損なうということはなくなって、透明性において窓ガラスと一体感を有して違和感がなく、窓ガラスの本来的機能を損なうことなく、結露自体の発生を防止することができる。
【００４２】
又、外気は内外に取り付けられた結露防止パネル部材における中空部内の動かない空気層と、窓ガラスと各結露防止パネル部材との空間部内の動かない空気層との二重乃至四重の空気層により遮断されて、室内には伝わらず、結露防止効果が格段と向上する。
【０４３】
又、従来のような吸水性ポリマーを使用する必要がないから、多量の水や水蒸気を吸収したときに吸水性ポリマーの脱落や移動がなく、室内等の環境向上に寄与し得る。

[0013]
In FIG. 1, a dew condensation prevention panel member is attached to the periphery of the inside (inside air side) surface of the window glass 20 with the window frame omitted.
[0014]
The anti-condensation panel member 30 is a plate-like body made of a polycarbonate material having characteristics such as excellent transparency, weather resistance, heat resistance, and self-extinguishing characteristics even when burned. It has a slightly smaller similar shape.
[0015]
In the dew condensation prevention panel member 30, hollow portions 34 are formed at equal intervals in a fixed direction between the opposing panel surface portions 31, 32 via an appropriate number of partition portions 33, and opening portions at both ends of each hollow portion Is formed into a hermetic seal portion 35 by heat sealing or the like so that air in each hollow portion 34 does not move.
[0016]
The dew condensation prevention panel member 30 configured in this way has a function of reducing the cold air region by itself and preventing dew condensation.
[0017]
That is, because the window glass side and the wall surface side of the building in contact with the outside air feel cold because there is a cold air region there, the dew condensation prevention panel member 30 has the effect of reducing such a cold air region, The fact that the cold air region is reduced means that the cold outdoor air is prevented from entering the room and the temperature difference between the internal and external air is reduced, thereby preventing condensation.
[0018]
In the cool air region, the thicker the entire thickness D of the dew condensation prevention panel member 30 is, and the thicker the thickness d of the panel surface portions 31 and 32 is, the more the air in each hollow portion 34 is moved. The area becomes smaller and the dew condensation prevention effect becomes remarkable.
[0019]
Incidentally, it is preferable that the dew prevention panel member 30 has a total thickness D of 3 to 9 mm and a thickness d of the panel surface portions 31 and 32 of 0.3 to 0.5 mm.
[0020]
As illustrated in FIGS. 8 to 11, the double-sided adhesive tape 40 to which the dew condensation prevention panel member 30 is attached is excellent in weather resistance and easily stretches without being broken when pulled. An adhesive layer 42 and a mesh-like peeling auxiliary member 43 made of a resin material such as polyester and a release paper 44 are laminated on both surfaces of 41, and have an appropriate thickness.
[0021]
The double-sided pressure-sensitive adhesive tape 40 has one pressure-sensitive adhesive layer 42 separated into the peripheral edge (four sides) of the dew condensation prevention panel member 30 via the mesh-like peeling auxiliary member 43, and at each corner, both vertical and horizontal surfaces. Each end of the adhesive tape 40 abuts and adheres in such a manner that the heel is also integrally adhered, and as shown in FIGS. 1 and 2, the rubber in the double-sided adhesive tape 40 in each of the vertical and horizontal directions. Only the base material 41 is attached with a state of slightly protruding outside the panel surface portion 31 (32) of the dew condensation prevention panel member 30, and the end 41a of the rubber base material 41 that comes out is dew condensation described later. This is a knob portion when the prevention panel member 30 is peeled off from the window glass 20.
[0022]
Next, on the inner side (inside air side) of the window glass 20, the dew condensation prevention panel member 30 passes through the other adhesive layer 42 and the mesh-like peeling auxiliary member 43 in the double-sided pressure-sensitive adhesive tape 40, and the window glass surface and the dew condensation prevention panel member 30. A space portion 50 is formed between the panel surface portion 32 and the panel surface portion 32 so as to be adhesively sealed.
[0023]
In this adhesive attachment to the window glass 20, the dew condensation prevention panel member 30 is made of polycarbonate and has a small expansion and contraction and dimensional stability. However, from the viewpoint of further stability, the dew condensation prevention panel member 30 is made into a window glass by expansion and contraction. In order not to be detached from 20, a play width 21 is provided around the window glass 20 for installation.
[0024]
In a state in which the dew condensation prevention panel member 30 is attached to the inside (inside air side) of the window glass 20, the outside air is a non-moving air layer in each hollow portion 34 in the dew condensation prevention panel member 30, and the window glass 20 and the dew condensation prevention panel member. This is blocked by the non-moving air layer in the space 50 and 30 and is not transmitted to the room, and the cold air region becomes small (the temperature difference between the outside air and the inside air becomes small), thereby preventing condensation.
[0025]
When it is necessary to peel off the dew condensation prevention panel member 30 from the window glass 20, the rubber base material 41 can be easily formed by holding the end 41 a of the rubber base material 41 in each double-sided adhesive tape 40 and pulling it outward. And the adhesive width between the dew condensation prevention panel member 30 and the window glass 20 is adhered with an adhesive coming out from the mesh of each mesh-like peeling assisting member 43, and the adhesive area is reduced. Therefore, the dew condensation prevention panel member 30 can be easily peeled from the window glass 20 by the action of the mesh-like peeling auxiliary member 43.
[0026]
As the double-sided pressure-sensitive adhesive tape, the double-sided pressure-sensitive adhesive tape 60 configured as the interphase peeling tape shown in FIGS. 10 and 11 can be used instead of the double-sided pressure-sensitive adhesive tape 40 shown in FIGS. 8 and 9.
[0027]
The double-sided pressure-sensitive adhesive tape 60 includes a pair of tape bodies 61 in which a mesh-like peeling auxiliary member 66 for interphase peeling is sandwiched, and one end portion 66 a slightly protrudes from the ends of the pair of tape bodies 61. Has been.
[0028]
The pair of tape bodies 61 is formed by providing a pressure-sensitive adhesive layer 63 on both sides of a rubber base material 62 and laminating a mesh-like peeling auxiliary member 64 and a release paper 65 on each pressure-sensitive adhesive layer 63 facing outward. Then, the respective adhesive layers 63 facing inward are adhered to both surfaces of a mesh-like peeling auxiliary member 66 for phase separation, thereby forming a double-sided pressure-sensitive adhesive tape 60 for phase separation.
[0029]
The attachment of the dew condensation prevention panel member 30 by the double-sided adhesive tape 60 is not particularly shown, but the adhesive layer 63 in one tape body 61 is disposed around the dew condensation prevention panel member 30 in the same manner as in the case of the double-sided adhesive tape 40. Next, the pressure-sensitive adhesive layer 63 in the other tape body 61 is adhesively sealed by forming a space 50 inside the window glass 20 (inside air).
[0030]
When it is necessary to peel off the dew condensation prevention panel member 30 from the window glass 20, if only the end 66a of the mesh-like peeling auxiliary member 66 for phase separation in each double-sided adhesive tape 60 is pulled outward, a pair The tape body 61 becomes a belly cracked state, and the dew condensation prevention panel member 30 is separated from the window glass 20. Thereafter, the tape bodies 61 adhered to the window glass 20 and the dew condensation prevention panel member 30 may be removed.
[0031]
12 and 13 show another example of the window glass dew condensation prevention structure according to the present invention. In this example, the dew condensation prevention panel member is provided on both the inside (inside air side) and outside (outside air side) of the window glass. By adhering to each other, a high dew condensation prevention effect can be obtained particularly in cold regions where the cold is strong.
[0032]
In FIG. 12, the dew condensation prevention panel member 30 inside the window glass 20 is not shown for the purpose of simplifying the display of the drawing.
[0033]
In FIG. 12, a dew condensation prevention panel member 70 is adhesively sealed to the outside (outside air side) of the window glass 20 with a space 50 through a double-sided adhesive tape 40 (or a double-sided adhesive tape 60).
[0034]
The dew condensation prevention panel member 70 is in the form of a soft film made of a polycarbonate material, and is structurally the same as the plate shaped dew condensation prevention panel member 30 and is merely a hard plate or soft film. It is only the difference.
[0035]
Therefore, the description about a structure is abbreviate | omitted. Further, the attachment or detachment of the dew condensation prevention panel member 70 to the outside (outside air side) of the window glass 20 with the double-sided pressure-sensitive adhesive tape 40 (or the double-sided pressure-sensitive adhesive tape 60) is the same as the case of the dew condensation prevention panel member 30. Detailed description thereof will be omitted.
[0036]
However, the condensation prevention panel member attached to the outside (outside air side) of the window glass 20 is not a plate-like body but a film-like condensation prevention panel member 70 even if it is blown off by an external strong wind or the like. This is because, unlike a plate-like body, it is not dangerous.
[0037]
As described above, the dew condensation prevention panel member 70 is adhered by forming the space portions 50 on the four sides on the outer side (outside air side) of the window glass 20, but in order not to be blown away by a strong external wind or the like, FIG. As shown schematically in FIG. 1, one end 70 a of the dew condensation prevention panel member 70 is sandwiched and attached to the inside (inside air side) between the window frame 22 and the end face of the structure 80.
[0038]
14 and 15 show still another example of the dew condensation prevention panel member used in the window glass dew condensation prevention structure according to the present invention. The dew condensation prevention panel member 80 is entirely made of a transparent resin such as polyethylene. An intermediate sheet 83 made of a material and having two or more sheets 81 and 82 and a cell-like portion 84 sandwiched between the sheets 81 and 82 and sealed with air by high frequency sealing is formed regularly or irregularly. The air bubble is made of resin and contains air bubbles, and the surface of the sheets 81 and 82 is not particularly shown but has a design such as a satin pattern or a lace pattern by embossing.
[0039]
Although not specifically illustrated, the dew condensation prevention panel member 80 is formed on the inside (inside air side) or inside (inside air side) and outside (outside air side) of the window glass 20 in the same manner as the dew condensation prevention panel members 30 and 70. In the same manner as described above, the anti-condensation panels on both the inner side (inside air side) and the inner and outer sides are attached with the space 50 provided between the window glass 20 via the double-sided adhesive tapes 40 and 60 in the same manner as described above. The outside air is blocked by the non-moving air layer in the bubble portion 84 of the member 80 and the non-moving air layer in the space portion 50 between the inside and outside dew condensation prevention panel member 80 and the window glass 20, and is transmitted to the room. Therefore, the cold air region becomes small (the temperature difference between the outside air and the inside air becomes small), and condensation is prevented.
[0040]
In addition, according to this dew condensation prevention panel member 80 embossed with a design such as a satin pattern or a lace pattern, the indoor atmosphere can be enhanced.
[0041]
【The invention's effect】
Thus, according to the present invention, the conventional room is not darkened and the atmosphere is not impaired, the transparency has a sense of unity with the window glass, and there is no sense of incongruity, and the original function of the window glass is impaired. Therefore, the occurrence of condensation itself can be prevented.
[0042]
The outside air is a double or quadruple air layer composed of a non-moving air layer in the hollow portion of the dew condensation preventing panel member attached inside and outside and a non-moving air layer in the space between the window glass and each dew condensation preventing panel member. Is prevented from being transmitted to the room, and the effect of preventing condensation is greatly improved.
[043]
Further, since it is not necessary to use a conventional water-absorbing polymer, the water-absorbing polymer does not fall off or move when a large amount of water or water vapor is absorbed, which can contribute to the improvement of the environment such as a room.
