Description

【０００１】
【発明の属する技術分野】
本発明は蓄熱した熱を制御して放熱することにより床暖房する蓄熱床暖房パネルの構造に関するものである。
【０００２】
【従来の技術】
従来、床暖房装置は図１５に示すように構成されていた。大引１の上に合板２を貼り、合板２の上に大引１と直交するように複数本の根太３を敷設してあり、隣り合う根太３間にヒータ４と蓄熱材５を敷設してある。合板２の下面側には断熱材６を装着してあり、また根太３間の適所にも断熱材７を介装してある。また根太３間でヒータ４の端部に対応する位置には接続ボックス８を装着してあり、ヒータ４に給電する送り線１０を接続ボックス８に接続してある。根太３の部分では根太３に貫通するように穿孔した穴９に送り線１０を挿通してある。蓄熱材５の上には空気を出し入れすることにより膨張収縮する袋体よりなり且つ膨張収縮により蓄熱材５から放熱される放熱量を制御する放熱制御アクチュエータを積層してあり、放熱制御アクチュエータの上から根太３上に床面板を貼っている。
【０００３】
【発明が解決しようとする課題】
ところで、上記従来例では、根太３間に設置したヒータ４の電気接続は、根太３に穴９を開け、送り線１０を穴９に通して結線していたため、施工が大変面倒（根太３間が狭いので電気ドリルが入りにくく穴９が開けずらい）、根太３に大きな穴９をあけなればならないので、根太の強度が大幅に低下する等の問題点があった。また接続ボックス８がヒータ４または蓄熱材５等の近傍に設置されるため、接続ボックス（電気接続部）８の温度が高く、接点の酸化劣化が進みやすい。また床面板を貼った後は床面板を剥がさないとメンテナンスができないという問題もある。
【０００４】
本発明は叙述の点に鑑みてなされたものであって、ヒータに給電するための電気接続が容易にできる蓄熱床暖房パネルを提供することを課題とする。
【０００５】
【課題を解決するための手段】
上記課題を解決するため本発明の請求項１の蓄熱床暖房パネルは、ヒータ４の上に蓄熱材５を積層し、空気を出し入れすることにより膨張収縮する袋体よりなり且つ膨張収縮により蓄熱材５から放熱される放熱量を制御する放熱制御アクチュエータ１１を蓄熱材５の上に積層し、放熱制御アクチュエータ１１の上方に床面板１２を貼ってパネル化した蓄熱床暖房パネルであって、ヒータ４に給電するための横送り線１３や横接続コネクター１４を収める横接続用凹部１５ａと、放熱制御アクチュエータ１１に空気を供給し且つ空気を横に送るヘッダーダクト３６とをパネルの長手方向の一端側に並べて設けて成ることを特徴とする。ヒータ４と蓄熱材５と放熱制御アクチュエータ１１と床面板１２とを組み合わせてパネル化した蓄熱床暖房パネルであることにより床暖房装置の施工が容易にできる。ヒータ４に給電するための横送り線１３や横接続コネクター１４を収める横接続用凹部１５ａを床面板１２に設けたことにより、床面板１２に予め設けた横接続用凹部１５ａに横送り線１３や横接続コネクター１４を配置して電気的に接続できて電気接続の施工が容易になり、また従来のように根太３に穴をあけたりする必要がなくて根太３を傷付けるおそれがなくなり、さらに床面板１２の横接続用凹部１５ａに横接続コネクター１４を配置することにより、ヒータ４や蓄熱材５で横接続コネクター１４が加熱されにくくなり、横接続コネクター１４の接点の温度が下がるので接点の長寿命化が図れる。またヘッダーダクト３６にて放熱アクチュエータ１１へ供給する空気の配管が容易にできる。
【０００６】
また本発明の請求項２の蓄熱床暖房パネルは、ヒータ４の上に蓄熱材５を積層し、空気を出し入れすることにより膨張収縮する袋体よりなり且つ膨張収縮により蓄熱材５から放熱される放熱量を制御する放熱制御アクチュエータ１１を蓄熱材５の上に積層し、放熱制御アクチュエータ１１の上方に床面板１２を貼ってパネル化した蓄熱床暖房パネルであって、ヒータ４に給電するために縦送り線１６や縦接続コネクター１７を収める縦接続用凹部１５ｂと、放熱制御アクチュエータ１１に供給する空気を縦方向に送るために接続する空気ジョイントとをパネルの長手方向に端部に設けて成ることを特徴とする。ヒータ４と蓄熱材５と放熱制御アクチュエータ１１と床面板１２とを組み合わせてパネル化した蓄熱床暖房パネルであることにより床暖房装置の施工が容易にできる。ヒータ４に給電するための縦送り線１６や縦接続コネクター１７を収める縦接続用凹部１５ｂを床面板１２に設けたことにより、床面板１２に予め設けた縦接続用凹部１５ｂに縦送り線１６や縦接続コネクター１７を配置して電気的に接続できて電気接続の施工が容易になり、また従来のように根太３に穴をあけたりする必要がなくて根太３を傷付けるおそれがなくなり、さらに床面板１２の縦接続用凹部１５ｂに縦接続コネクター１７を配置することにより、ヒータ４や蓄熱材５で縦接続コネクター１７が加熱されにくくなり、縦接続コネクター１７の接点の温度が下がるので接点の長寿命化が図れる。また空気ジョイントにて放熱アクチュエータ１１へ供給する空気の配管が容易にできる。
【０００７】
また本発明の請求項３の蓄熱床暖房パネルは、請求項１または請求項２において、床面板１２の上面に横接続用凹部１５ａまたは縦接続用凹部１５ｂを設けたことを特徴とする。床面板１２の上から配線の施工ができて施工が容易にできる。
【０００８】
また本発明の請求項４の蓄熱床暖房パネルは、請求項１または請求項２において、床面板１２の下面に横接続用凹部１５ａまたは縦接続用凹部１５ｂを設けたことを特徴とする。横接続用凹部１５ａまたは縦接続用凹部１５ｂで配線の施工をした後、横接続用凹部１５ａまたは縦接続用凹部１５ｂの開口を蓋したりする必要がなくなる。
【０００９】
また本発明の請求項５の蓄熱床暖房パネルは、請求項１乃至請求項４のいずれかにおいて、床面板１２と略同厚の偏平な薄型の空気供給用のヘッダーダクト３６を床面板１２に埋設し、ヘッダーダクト３６を放熱制御アクチュエータ１１に接続して成ることを特徴とする。放熱制御アクチュエータ１１を駆動するための空気を供給する部分の施工が容易にできる。
【００１０】
また本発明の請求項６の蓄熱床暖房パネルは、請求項１乃至請求項４のいずれかにおいて、放熱制御アクチュエータ１１に空気を送り込むための送り込み口３８を放熱制御アクチュエータ１１の下面のシートに設けて成ることを特徴とする。放熱制御アクチュエータ１１の耐久性を向上できる。
【００１１】
また本発明の請求項７の蓄熱床暖房パネルは、請求項１乃至請求項６のいずれかにおいて、放熱制御アクチュエータ１１に空気を送るための空気経路を隣接する蓄熱床暖房パネル間では一方の蓄熱床暖房パネルの雄型空気ジョイント２４と他方の蓄熱床暖房パネルの雌型空気ジョイント２５とを嵌合することで接続する構造とし、雄型空気ジョイント２４の近傍に雄型空気ジョイント２４より突出する位置決め突起４０をパネル端面から突設すると共に雌型空気ジョイント２５の近傍のパネル端面に上記位置決め突起４０に嵌合する位置決め凹部４１を設けて成ることを特徴とする。雄型空気ジョイント２４と雌型空気ジョイント２５と嵌合するとき、位置決め突起４０と位置決め凹部４１との嵌合にて先に位置決めされるものであって、位置が合わないと雄型空気ジョイント２４と雌型空気ジョイント２５とが嵌合されないために雄型空気ジョイント２４がパネル端面に当たって破損するのを防止できる。
【００１２】
【発明の実施の形態】
蓄熱床暖房パネルＡは床に並べて敷設することにより床暖房装置を施工するものであり、図１に示すような横接続用蓄熱床暖房パネルＡ１と図４に示すような縦接続用蓄熱床暖房パネルＡ２とがある。この蓄熱床暖房パネルＡはヒータ４、蓄熱材５、放熱アクチュエータ１１、床面板１２を組み合わせてパネル化したものである。
【００１３】
本例の場合、潜熱蓄熱材のような蓄熱材５は蓄熱ボード２０の充填空間内に充填してある。蓄熱ボード２０は偏平な矩形箱状で内部が充填空間となった筐体２０ａの周縁に立ち上がり壁２０ｂを設けると共に立ち上がり壁２０ｂの上端に周縁の適所で取り付け片２０ｃを水平に突設して形成されている。かかる蓄熱ボード２０はポリプロピレンのような合成樹脂にて一体に形成されている。蓄熱ボード２０の筐体２０ａの下面には通電することより発熱するヒータ４を蓄熱ボード２０の下面の全面に亙って装着してある。かかるヒータ４を装着するとき、粘着したり、その他の機械的方法で固定したりしてある。
【００１４】
蓄熱ボード２０の筐体２０ａの上面上の立ち上がり壁２０ｂで囲まれる部分には放熱制御アクチュエータ１１を収納してあり、放熱制御アクチュエータ１１の上にアルミニウム箔２１を積層してあり、蓄熱ボード２０の立ち上がり壁２０ｂの上端の上には蓄熱ボード２０の上面の全面を覆うように合板のような床面板１２を配置してあり、取り付け片２０ｃを床面板１２にビス等で固定することにより、蓄熱ボード２０と床面板１２とを一体化してある。
【００１５】
上記放熱制御アクチュエータ１１は空気を出し入れすることにより膨張収縮する袋体よりなり且つ膨張収縮により蓄熱材５から放熱される放熱量を制御するものである。この放熱制御アクチュエータ１１の原理は本特許出願人が先に出願した特開平１１−３３７０９５号公報に開示される袋体と同じであるため詳しい説明は省略する。放熱制御アクチュエータ１１は矩形状の上シートと矩形状の下シートを重ね、周縁をヒートシールすることにより袋状に形成されている。かかる上シートは例えば厚さ２５μｍのＰＥＴシート、下シートは例えば厚さ３０μｍのＣＰＰシートである。
【００１６】
横接続用蓄熱床暖房パネルＡ１では放熱制御アクチュエータ１１の一端の上面にダクト接続用ジョイント２３を設けてあり、放熱制御アクチュエータ１１の他端に縦送り用の雄型空気ジョイント２４を設けてある。ダクト接続用ジョイント２３はプラスチック成形品等であり、後述するヘッダーダクト３６と接着等で接続できるようになっている。雄型空気ジョイント２４はポリプロピレンのようなプラスチック成形品であり、放熱制御アクチュエータ１１に熱融着等で取り付けてある。またこの雄型空気ジョイント２４は蓄熱ボード２０の立ち上がり壁２０ｂに挿通して外に突出させてある。縦接続用蓄熱床暖房パネルＡ２では放熱制御アクチュエータ１１の一端に縦送り用の雌型空気ジョイント２５を設けてあり、放熱制御アクチュエータ１１の他端に縦送り用の雄型空気ジョイント２４を設けてある。雌型空気ジョイント２５はポリプロピレンのようなプラスチック成形品であり、放熱制御アクチュエータ１１に熱融着等で取り付けてある。かかる雌型空気ジョイント２５と雄型空気ジョイント２４は蓄熱ボード２０の立ち上がり壁２０ｂに挿通して突出させてあり、雌型空気ジョイント２５は雄型空気ジョイント２４に嵌め込み等で着脱自在に接続できるようになっている。また縦方向の末端に位置する縦接続用蓄熱床暖房パネルＡ２では雌型空気ジョインド２５にエンドキャップ２６を着脱自在に取り付けて閉塞できるようになっている。
【００１７】
また床面板１２の上面に電気配線用の凹部１５が設けられるが、この凹部１５には横接続用凹部１５ａと縦接続用凹部１５ｂとがある。横接続用蓄熱床暖房パネルＡ１では床面板１２の一端に横接続用凹部１５ａを穿設してあり、床面板１２の他端に縦接続用凹部１５ｂを設けてある。この横接続用凹部１５ａの長手方向の中央には横接続コネクター１４を収納して設置してあり、この横接続コネクター１４とヒータ４とを接続してある。また横送り線１３は横接続用凹部１５ａに収納するように挿通してあり、横送り線１３の端部を横接続用コネクター１４に接続してある。この横送り線１３や横接続コネクター１４を横接続用凹部１５ａに収納した状態で横接続用凹部１５ａの上面開口に横接続部用蓋２７を着脱自在に被着して閉塞できるようになっている。また縦接続用凹部１５ｂは縦接続コネクター１７を収納して設置してあり、この縦接続コネクター１７に縦送り線１６を接続できるようになっている。この縦送り線１６や縦接続コネクター１７を収納した状態で縦接続用凹部１５ｂの上面開口に縦接続部用蓋２８を着脱自在に被着して閉塞できるようになっている。
【００１８】
縦接続用蓄熱床暖房パネルＡ２では床面板１２の一端及び他端に縦接続用凹部１５ｂを設けてある。一端の縦接続用凹部１５ｂには縦送り線１６を収納してあり、この縦送り線１６をヒータ４を接続してある。この縦送り線１６は引き出して隣接の縦接続コネクター１７に接続するためにコード長さに余裕を持たせてある。他端の縦接続用凹部１５ｂには縦接続コネクター１７を収納してあり、縦接続コネクター１７をヒータ４に接続してある。かかる両端の縦接続用凹部１５ｂの上面開口には縦接続部用蓋２８を着脱自在に被着して閉塞できるようになっている。横接続用蓄熱床暖房パネルＡ１の一端には放熱制御アクチュエータ１１に空気を供給するためのヘッダーダクト３６を設けられるが、このヘッダーダクト３６は床面板１２の厚さと略同じ厚さになっており、床面板１２に埋設するように床面板１２と一体に設けてある。ヘッダーダクト３６はアルミニウム等の押出成形品である。かかるヘッダーダクト３６は前述のようにダクト接続用ジョイント２３と接着等で接続してある。ヘッダーダクト３６の長手方向の端部はゴムシール部材２９を介して接続されるようにしてある。
【００１９】
上記のように構成せる横接続用蓄熱床暖房パネルＡ１や縦接続用蓄熱床暖房パネルＡ２を用いて図６に示すように施工される。横接続用蓄熱床暖房パネルＡ１は横方向に複数枚並べて敷設され、各横接続用蓄熱床パネルＡ１を親パネルとして縦方向に複数枚の縦接続用蓄熱床暖房パネルＡ２が並べて敷設される。建物の床には大引１の上に大引１と直交するように複数の根太３が等間隔に架設されているが、上記蓄熱床暖房パネルＡは各根太３間に嵌め込むように敷設される。蓄熱床暖房パネルＡを敷設したとき床面板１２の端縁が根太３の上に載設される。大引１間には断熱材６を装填してある。隣接する横接続用蓄熱床暖房パネルＡ間では隣り合う横接続用凹部１５ａが連通させられ、横接続用凹部１５ａに横送り線１３を挿通して収納され、横送り線１３の端部が横接続コネクター１４に接続され、横接続用凹部１５ａの上面の開口に横接続部用蓋２７が被着される。また隣接する横接続用蓄熱床暖房パネルＡ１間で隣接するヘッダダクト３６の端部同士が差し込み接続される。また横接続用蓄熱床暖房パネルＡ１と縦接続用蓄熱床暖房パネルＡ２とが隣接する部分や縦接続用蓄熱床暖房パネルＡ２が縦方向に隣接する部分では隣接する縦接続用凹部１５ｂ間で縦送り線１６の端部が縦接続コネクター１７に接続される。図６で符号Ｂに示す部分は縦送り線１６と縦接続コネクター１７の接続状態であり、符号Ｃに示す部分は未接続状態である。このように縦送り線１６と縦接続コネクター１７とを接続して縦接続用凹部１５ｂに収納した状態で縦接続用凹部１５ｂの上面開口に縦接続部用蓋２８が被着される。また横接続用蓄熱床暖房パネルＡ１と縦接続用蓄熱床暖房パネルＡ２とが隣接する部分や縦接続用蓄熱床暖房パネルＡ２が縦方向に隣接する部分では雌型空気ジョイント２５と雄型空気ジョイント２４とが差し込み接続される。また縦方向の末端に位置する縦接続用蓄熱床暖房パネルＡ２では雌型空気ジョイント２５にエンドキャップ２６が装着される。上記のように蓄熱床暖房パネルＡが敷設され、各蓄熱床暖房パネルＡのヒータ４に給電され、各蓄熱床暖房パネルＡの放熱制御アクチュエータ１１に空気が供給される。
【００２０】
また図７は他の例を示すものである。上記例では床面板１２の上面に横接続用凹部１５ａや縦接続用凹部１５ｂよりなる凹部１５を設けたが、本例の場合、床面板１２の下面側に横接続用凹部１５ａや縦接続用凹部１５ｂよりなる凹部１５を設けてある。本例の場合、床面板１２の端縁に近い部分で横接続用凹部１５ａに横接続コネクター１４を設置してあり、また横送り線１３のコード長には余裕を持たせてある。このように床面板１２の下面側に凹部１５を設けてあると、電気的接続の施工性は多少悪くなるが、凹部１５の開口を蓋で閉塞する必要がなくなる。上記のように横接続用蓄熱床暖房パネルＡ１の床面板１２の一端には床面板１２の厚さと略同じ厚さのヘッダーダクト３６が埋設するように取り付けられ、ヘッダーダクト３６と放熱制御アクチュエータ１１と接続してヘッダーダクト３６から放熱制御アクチュエータ１１に空気が供給されるようになっているが、このようにすると下記のように容易に施工できる。つまり、上記のようなヘッダーダクト３６を用いない場合、図１０に示すように根太３の下に空気配管３６′を通して空気配管３６′と放熱制御アクチュエータ１１とを接続しなければならない。この場合、根太３の下に空気配管３６′をくぐらせなければならなという問題や、部屋の隅等の火打ち３１のところでは空気配管３６′を通せなかったり、或いは通しにくい（火打ち３１の下をくぐらせなければならない）という問題があり、施工のしにくさがあると共に施工の信頼性を損なうという問題がある。しかし図８に示すようにヘッダーダクト３６を用いると、根太３より上で空気の送り経路を構成できるために施工がしやく、施工ミスを少なくできる。また火打ち３１のある部分でも無理な配管引き回しをせずに施工できる。
【００２１】
図９（ａ）はヘッダーダクト３６と放熱制御アクチュエータ１１とを接続する状態をさらに詳しく説明するものである。本例のヘッダーダクト３６は合成樹脂の押出成形品であり、例えば塩化ビニルにて形成されている。このヘッダーダクト３６の下面に連結穴３２を穿孔してあり、放熱制御アクチュエータ１１の上シート１１ａに連結穴３３を穿孔してある。そして連結穴３３の周囲に接着剤３４を塗布し、連結穴３２と連結穴３３を対応させるように上シート１１ａにヘッダーダクト３６を重ねて接着してある。かかる接着剤３４としては例えば変性オレフィン系接着剤がある。またヘッダーダクト３６の長手方向の端部同士は図８（ｂ）に示すようにゴムシール部材２９を介して接合される。ゴムシール部材２９は中央に突条２９ａを全周に亙って設け、突条２９ａを境にして左右にヘッダーダクト３６の内周に嵌合する嵌合部２９ｂを設けて形成されている。そして隣接するヘッダダクト３６の端部に嵌合部２９ｂを圧入することでゴムシール部材２９を介して気密的に接続してある。
【００２２】
また図１１は他の例を示すものである。本例は放熱制御アクチュエータ１１に空気配管から空気を送り込むための送り込み口３８を設ける例である。放熱アクチュエータ１１は上シート１１ａと下シート１１ｂとを重ねると共に周縁をヒートシールして形成されている。本例の場合、上シート１１ａと下シート１１ｂは例えば５０μｍのＰＥＴシートにて形成されている。送り込み口３８はポリプロピレン、ポリエチレン等の合成樹脂の成形品であり、送り込み口３８の鍔部３８ａを下シート１１ｂの下面で連結穴３３の周縁に当接し、熱融着または接着にて接合してある。接着するとき接着剤としては変性オレフィン系ホットメルト接着剤が好ましい。しかして空気を送ると図１１（ｂ）に示すように膨張する動作をし、空気を抜くと図１１（ｃ）に示すように収縮する逆動作をする。このように送り込み口３８を設けると、図１２のように周縁で上シート１１ａと下シート１１ｂとの間に設けるのに比べて下記のような利点がある。図１２に示すものの場合、上シート１１ａの周縁と下シート１１ｂの周縁との間の適宜の１箇所に送り込み口３８′を介装して融着したものであり、空気を送ると図１２（ｂ）に示すように膨張する動作をし、空気を抜くと図１２（ｃ）に示すように収縮する逆動作をする。かかるもののように放熱制御アクチュエータ１１の周縁に送り込み口３８′を融着して設けると、送り込み口３８′の周辺が皺になり、動作を繰り返す際に同じ場所に同じ形の皺があらわれるため、放熱制御アクチュエータ１１の素材の耐久性によくない影響を与えるという問題があり、また逆動作させる際には、送り込み口３８′の周辺は、重力が働いても完全には逆動作が完了せず（図１２（ｃ）の符号Ｄに示す部分が逆動作未完部分である）、部分的なロスが発生するという問題があり、耐久性、機能性を損なうという問題がある。しかし、図１１に示すように放熱制御アクチュエータ１１の下シート１１ｂの下面に送り込み口３８を設けると、放熱制御アクチュエータ１１に無用な皺ができず、素材の耐久性がよくなり、また逆動作させる場合、重力で完全に逆動作が完了し、所望の性能を発揮できる。
【００２３】
また図１３は他の例を示すものである。本例も上例と基本的に同じであり、異なる点だけを主に述べる。横接続用蓄熱床暖房パネルＡ１の一端の両側には放熱制御アクチュエータ１１と連通する雄型空気ジョイント２４及び雌型空気ジョイント２５が設けられており、雄型空気ジョイント２４や雌型空気ジョイント２５を介して放熱制御アクチュエータ１１に空気が供給できるようになっている。雄型空気ジョイント２４と雌型空気ジョイント２５とは差し込むことにより嵌合接続し得るようになっている。横接続用蓄熱床暖房パネルＡ１の他端にも放熱制御アクチュエータ１１と連通する縦送り用の雌型空気ジョイント２５を設けてある。縦接続用蓄熱床暖房パネルＡ２でも一端に放熱制御アクチュエータ１１と連通する縦送り用の雄型空気ジョイント２４を設けてあると共に他端に放熱制御アクチュエータ１１と連通する雌型空気ジョイント２５を設けてある。雌型空気ジョイント２５はパネル端面に臨ませてあり、雄型空気ジョイント２４はパネル端面から外に突出している。
【００２４】
上記のように構成せる横接続用蓄熱床暖房パネルＡ１や縦接続用蓄熱床暖房パネルＡ２は図６に敷設されるが、隣り合う横接続用蓄熱床暖房パネルＡ１，Ａ１間、隣り合う縦接続用蓄熱床暖房パネルＡ２，Ａ２間、隣り合う横接続用蓄熱床暖房パネルＡ１と縦接続用蓄熱床暖房パネルＡ２との間では空気の配管が雄型空気ジョイント２４と雌型空気ジョイント２５との嵌合接続で接続される。ところで、雄型空気ジョイント２４と雌型空気ジョイント２５とを嵌合接続するとき、図１４（ａ）のようにジョイントの位置がずれた場合、雄型空気ジョイント２４を破壊してしまいやすいという問題がある。そこで、本発明では次のように位置決め突起４０と位置決め凹部４１とよりなる位置決め手段を設けた。雄型空気ジョイント２４の近傍の両側にはパネル端面から突出するようにダボのような位置決め突起４０を突設してあり、雌型空気ジョイント２５の近傍の両側にはパネル端面から凹没するようにダボ穴のような位置決め凹部４１を設けてある。上記ダボのような位置決め突起４０は雄型空気ジョイント２４より外に突出するように突設してある。これにより、雄型空気ジョイント２４と雌型空気ジョイント２５とを嵌合接続するとき、位置決め突起４０と位置決め凹部４１とが対応する位置に合わさなければ図１４（ｂ）のように位置決め突起４０が対向するパネル端面に当たって雄型空気ジョイント２４と雌型空気ジョイント２５とを嵌合できなく、位置決め突起４０と位置決め凹部４１とが嵌合する位置に合わせたとき、位置決め突起４０と位置決め凹部４１の嵌合にて位置決めされると共に雄型空気ジョイント２４と雌型空気ジョイント２５とが合致して雄型空気ジョイント２４と雌型空気ジョイント２５が差し込みにて嵌合接続される。これにより雄型空気ジョイント２４と雌型空気ジョイント２５とを接続するとき雄型空気ジョイント２４が破壊されにくい。なお、本例では位置決め突起４０をダボとし、位置決め凹部４１をダボ穴とする例について述べたが、位置決め突起４０を雄実状とし、位置決め凹部４１を雌実状としてもよい。

In the case of the one shown in FIG. 12, it is fused at one appropriate location between the peripheral edge of the upper sheet 11a and the peripheral edge of the lower sheet 11b through the feed port 38 '. The operation of expanding as shown in FIG. 12B is performed, and the operation of contracting as shown in FIG. When the feed port 38 'is provided by fusing the peripheral edge of the heat radiation control actuator 11 like this, the periphery of the feed port 38' becomes wrinkled, and when the operation is repeated, wrinkles of the same shape appear in the same place. There is a problem that the durability of the material of the heat radiation control actuator 11 is adversely affected, and when the reverse operation is performed, the reverse operation is not completely completed around the feed port 38 'even if gravity acts. (The portion indicated by the symbol D in FIG. 12C is the portion where the reverse operation is not completed), there is a problem that a partial loss occurs, and there is a problem that durability and functionality are impaired. However, if the feed port 38 is provided on the lower surface of the lower sheet 11b of the heat radiation control actuator 11 as shown in FIG. 11, the heat radiation control actuator 11 does not wrinkle unnecessarily, the durability of the material is improved, and the operation is reversed. In this case, the reverse operation is completely completed by gravity, and the desired performance can be exhibited.
