Description

【0001】
【発明の属する技術分野】
本発明は、太陽電池パネルを屋根に固定している太陽電池装置に関する。
【0002】
【従来の技術】
太陽電池パネルは、屋根にしっかりと固定する必要がある。台風等の強風で太陽電池パネルが移動しないように固定するためである。このことを実現することを目的として、太陽電池パネルを屋根に固定する構造が、以下の参考文献1と2に記載される。
【0003】
【特許文献1】
特開平11−247387号公報
【特許文献2】
特開平7−202242号公報
【0004】
参考文献1の公報には、図1に示す構造で太陽電池パネル1を屋根11に固定する構造が記載され、参考文献2の公報には、図2に示す構造で太陽電池パネル1を屋根11に固定する構造が記載される。これ等の太陽電池装置は、屋根11に固定される固定具2と、この固定具2の連結溝2Aに連結している頭付ボルト3と、頭付ボルト3を貫通孔4Aに挿通している押さえ具4と、押さえ具4の係止部4Bをスライド溝1Aに案内している太陽電池パネル1とを備える。この太陽電池装置は、頭付ボルト3にねじ込むナット7で押さえ具4を固定具2に連結して、頭付ボルト3でもって太陽電池パネル1を屋根11に固定している固定具2に連結している。
【0005】
【発明が解決しようとする課題】
これ等の公報に記載される太陽電池装置は、屋根に固定している固定具を太陽電池パネルの周縁に沿って細長い形状としているので、固定具が長くなる欠点がある。また、固定具を太陽電池パネルの周縁に沿って正確な位置に固定する必要がある。この弊害は、本出願人が検討したところ、未発売で、未発表の図3と図4に示すように、短い固定具2を、太陽電池パネル1に周縁に対して交差する姿勢で屋根に固定して解消できる。(図3、図4は、太陽電池パネル1、固定具2の位置関係を示すための上から見た概略図である。)この取付構造は、頭付ボルトを太陽電池パネルの周縁に直交する方向に移動でき、また、押さえ具を太陽電池パネルのスライド溝に沿って移動できるので、頭付ボルトを太陽電池パネルの周縁に対して縦横の両方向に移動して、屋根に固定できる。このため、固定具を正確に位置決めしないで屋根に簡単に能率よく固定できる特長がある。また、固定具を短くできるので、固定具を安価にできる特長もある。
【0006】
ただ、この構造で太陽電池パネルを屋根に固定すると、頭付ボルトが固定具の端部に移動して、しっかりと固定できないことがある。頭付ボルトを連結溝2Aに沿って自由に移動できるからである。また、固定具2に設けている連結溝2Aの開口端面が外部に表出するので、たとえば、着色したアルミニウムの引き抜き材を所定の長さに切断して製造される固定具の場合、着色されない切断面が外部に表出してしまう。金属の切断面は、屋根の色とは極めて異なる色であるから、これが目だって屋根を美しい色彩にできなくなる欠点がある。
【0007】
本発明は、このような欠点を解決することを目的に開発されたものである。本発明の重要な目的は、安価で短い固定具を使用して、簡単かつ容易に、しかもしっかりと太陽電池パネルを屋根に固定できる太陽電池装置を提供することにある。
また、本発明の他の大切な目的は、固定具にアルミニウムの引き抜き材を使用して、切断面を屋根に適合する色にすることも可能である太陽電池装置を提供することにある。
【0008】
【課題を解決するための手段】
本発明の太陽電池装置は、屋根11に固定される固定具2と、この固定具2に頭部3Aを連結している頭付ボルト3と、この頭付ボルト3を貫通させる貫通孔4Aを開口すると共に、この貫通孔4Aに挿通される頭付ボルト3を介して固定具2に連結される押さえ具4と、この押さえ具4に設けている係止部4Bを案内するスライド溝1Aを周縁に有する太陽電池パネル1とを備える。固定具2は、頭付ボルト3の頭部3Aを係止するように開口部を狭くしている連結溝2Aを有する。この連結溝2Aは、固定具2の端部まで延長されて端部で開口されて、連結溝2Aの開口部から頭付ボルト3の頭部3Aを連結溝2Aに案内できる構造としている。この太陽電池装置は、固定具2の連結溝2Aに頭付ボルト3の頭部3Aを案内し、この頭付ボルト3でもって押さえ具4を屋根11に固定している固定具2に連結して太陽電池パネル1を屋根11に固定している。さらに、本発明の太陽電池装置は、固定具2と太陽電池パネル1との間にスペーサー5を挟着している。このスペーサー5は、固定具2と太陽電池パネル1との間に挟着される上面カバー部5Aと、固定具2の連結溝2Aの開口端面2aをカバーする端面カバー部5Bとを有し、上面カバー部5Aには連結溝2Aの全長よりも短いボルト孔5aを設けている。太陽電池装置は、固定具2に連結している頭付ボルト3を、スペーサー5のボルト孔5aに挿通して、頭付ボルト3が押さえ具4を介して太陽電池パネル1を固定具2に連結している。
【0009】
スペーサー5は、太陽電池パネル1のリード線を挿通する支持孔5bを設けることができる。さらに、スペーサー5は、上面カバー部5Aに端面カバー部5Bと位置決め凸部9とを設けて、位置決め凸部9と端面カバー部5Bとの間に固定具2を配置することができる。
【0010】
固定具2は、アルミニウムの引き抜き材とすることができる。さらに、固定具2は、連結溝2Aを太陽電池パネル1の側縁に対して直交する姿勢で屋根11に固定することができる。
【0011】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。ただし、以下に示す実施例は、本発明の技術思想を具体化するための太陽電池装置を例示するものであって、本発明は太陽電池装置を以下のものに特定しない。
【0012】
さらに、この明細書は、特許請求の範囲を理解しやすいように、実施例に示される部材に対応する番号を、「特許請求の範囲の欄」、および「課題を解決するための手段の欄」に示される部材に付記している。ただ、特許請求の範囲に示される部材を、実施例の部材に特定するものでは決してない。
【0013】
図5ないし図10に示す太陽電池装置は、屋根11に固定される固定具2と、この固定具2に頭部3Aを連結している頭付ボルト3と、この頭付ボルト3を貫通させる貫通孔4Aを開口しており、この貫通孔4Aに挿通される頭付ボルト3を介して固定具2に連結される押さえ具4と、この押さえ具4に設けている係止部4Bを案内するスライド溝1Aを周縁に有する太陽電池パネル1とを備えている。
【0014】
固定具2は、アルミニウムの引き抜き材を、たとえば5cm〜20cmの長さに切断したもので、断面中央に連結溝2Aを、両側にはサイド溝2Bを設けている。固定具2は、連結溝2Aの延在する方向を、屋根11の傾斜方向(図5に矢印で示す)と一致させる状態で屋根11に固定している。連結溝2Aは、頭付ボルト3の頭部3Aを抜けないように連結するために開口部を狭くしている。図の連結溝2Aは、開口部に互いに内側に突出するリブを設けて、開口部を狭くしている。図示しないが、連結溝は、対向する側面を傾斜面として、開口部を狭くすることもできる。連結溝2Aは、固定具2の端部まで延長されて端部で開口して、連結溝2Aの開口部から頭付ボルト3の頭部3Aを案内できる構造としており、挿入された頭付ボルト3の頭部3Aは連結溝2A内で回転できない寸法となっている。
【0015】
サイド溝2Bは、断面形状をコ字状としている。サイド溝2Bの底に円形に貫通する止孔2bを開口している。止孔2bは、固定具2の複数ヶ所に設けられて、ここに入れる止ビス6で固定具2をしっかりと屋根11に固定する。図の固定具2は、各々のサイド溝2Bに複数の止孔2bを設けている。止孔2bにねじ込まれる止ビス6は、頭部6Aがサイド溝2Bの内部にあって、固定具2の上面から突出することがない。ただ、固定具には必ずしもサイド溝を設ける必要はない。止孔の上面開口部を太くして、太い部分に止ビスの頭部を入れて、頭部が固定具の表面から突出しない構造にできるからである。止ビス6は、止孔2bから屋根11の野地板や瓦等の屋根材にねじ込まれて、固定具2を屋根11にしっかりと固定する。
【0016】
アルミニウムの引き抜き材である固定具2は、塗装した後に所定の長さに切断して製造される。塗装後に切断されるので、連結溝2Aの開口端面2aはアルミニウムの金属地肌が表出している。上面と下面と両側面は、屋根材に適合するように、黒色や焦げ茶色等の暗色に着色されている。ただ、本発明の太陽電池装置は、固定具を必ずしもアルミニウムの引き抜き材とする必要はない。固定具は、鉄、銅、ステンレス等の金属板をプレス加工し、あるいはアルミニウムを鋳造し、あるいは耐候性のプラスチックを成形して製造することもできる。
【0017】
図5に示すように、複数枚の太陽電池パネル1を屋根11に固定している太陽電池装置は、太陽電池パネル1の境界を連結する固定具2に、連結溝2Aが延在する方向に長くした形状の中間固定具2Mを利用して、2枚の太陽電池パネル1をしっかりと固定できる。なお、図5は、太陽電池装置を設置する途中を示しており、この構造は、上述の図4における太陽電池パネル1及び固定具2の位置関係と同様である。長い中間固定具2Mは、隣接する太陽電池パネル1を固定位置の調整幅を広くできると共に、図11に示すように、多数の止ビス6を使用して広い面積で屋根にしっかりと固定できる。この中間固定具2Mは、隣接する2枚の太陽電池パネル1をしっかりと固定できる。ただ、中間固定具2Mは、図6と図7に示すように太陽電池パネル1の外側外周縁を固定する固定具2と同じものを使用して、隣接する太陽電池パネル1を固定することもできる。また、図5、図11において確認できるように、板状スペーサー5Mを、太陽電池パネル1と、中間固定具2Mとの間に設けている。そして、このような固定具2は、上述の図3の配置位置においても、利用することができる。また、図3においては、固定具2を、連結溝2Aの延在方向が屋根の傾斜方向(図3に矢印で示す)と直角に交差するようにも配置している。このような固定具2、中間固定具2Mの各々は、屋根上の平面状鋼板上、或いは、一枚のスレート瓦上に設置されることになる。
【0018】
固定具2は、連結溝2Aが太陽電池パネル1のスライド溝1Aに交差するように、好ましくは直交する姿勢で屋根に固定される。とくに、最も下段に固定される太陽電池パネル1の下縁を固定する固定具2は、太陽電池パネル1のスライド溝1Aと連結溝2Aとが交差、好ましくは直交する姿勢で固定される。ただ、本発明の太陽電池装置は、必ずしも全ての固定具2を、連結溝2Aが太陽電池パネル1のスライド溝1Aと直交する姿勢で固定する必要はなく、たとえば、固定具2の連結溝2Aがスライド溝1Aと平行な姿勢となるように固定することもできる。この状態で固定される固定具2は、太陽電池パネル1を固定する位置をスライド溝1Aと直交する方向には移動できないので、この固定具2で太陽電池パネル1を最初に固定して位置決めし、その後、連結溝2Aをスライド溝1Aに対して交差する方向に配置している固定具2に固定するのがよい。
【0019】
押さえ具4は、ステンレス等の金属板を断面コ字状にプレス加工して、両側に係止部4Bを設けている。両側の係止部4Bは、図9の断面図に示すように、両端部分でスライド溝1Aの底に点接触するように、下縁をアーチ形状としている。この押さえ具4は、太陽電池パネル1のスライド溝1Aを係止部4Bの2点で押圧して、固定具2に固定する。押さえ具4は、頭付ボルト3を貫通させる貫通孔4Aを中央に設けている。この押さえ具4は、貫通孔4Aに頭付ボルト3を挿通し、頭付ボルト3にナット7をねじ込んでナット7で固定具2に固定される。貫通孔4Aは、コ字状に折曲している平面部分の中央に設けている。
【0020】
太陽電池パネル1は、光を受光して発電する多数の板状太陽電池1Bを封止した構造のパネル状本体を有し、その外周に外枠を備える構造であって、周縁に沿って断面L字状のスライド溝1Aを設けている。太陽電池パネル1は、電力取り出し用のリード線(図示せず)を接続している。このリード線は、固定具2で支持された太陽電池パネル1の下面、すなわち太陽電池パネル1と屋根との間に配線される。
【0021】
次に、本発明の特徴であるスペーサー5について、詳細に説明する。
スペーサー5は、金属板板をプレス加工して製作される。スペーサー5は、表面を黒や焦げ茶色等の暗色に着色している。スペーサー5と固定具2は、好ましくは同じ色、たとえば黒色に着色される。固定具2と同色のスペーサー5は、固定具2の開口端面2aを目だたないようにカバーできる。スペーサーは、必ずしも金属板で製作する必要はなく、硬質のプラスチックを成形して製造することもできる。スペーサー5及びスペーサー5Mを利用することにより、必要に応じて、これらを複数枚利用して、屋根のスレート瓦等上に設けられた固定具2上のスペーサー5及びスペーサー5Mの上面の高さを調整することができ、太陽電池パネル1を安定して設置することができる。
【0022】
スペーサー5は、図8と図10に示すように、全体の断面形状をL字状としている。スペーサー5は、固定具2と太陽電池パネル1との間に挟着される上面カバー部5Aと、固定具2の連結溝2Aの開口端面2aをカバーする端面カバー部5Bとを備える。上面カバー部5Aは、挿通する頭付ボルト3を所定の位置に配置するために、スリット状のボルト孔5aを開口している。ボルト孔5aは、固定具2の連結溝2Aの全長、いいかえると固定具2の全長よりも短くしている。スリット状のボルト孔5aは、頭付ボルト3をスリットに沿って移動できるので、頭付ボルト3の位置を調整しながら、頭付ボルト3を決められた範囲に固定する。ボルト孔5aは、必ずしもスリット状とする必要はなく、頭付ボルト3を挿通できる丸孔や多角形の孔とすることもできる。
【0023】
図の太陽電池装置は、頭付ボルト3を固定具2に中間ナット8で固定している。すなわち、頭付ボルト3には、頭付ボルト3を固定具2に固定する中間ナット8と、押さえ具4を固定するナット7を二重にねじ込んでいる。この取付構造は、中間ナット8で頭付ボルト3を固定具2に固定して、この頭付ボルト3に押さえ具4を固定できる特長がある。中間ナット8は、頭付ボルト3を完全に固定具2に固定する必要はない。押さえ具4を固定するために頭付ボルト3にねじ込むナット7を完全に締め込んで、頭付ボルト3を固定具2に移動しないように固定できるからである。さらに、中間ナット8は必ずしも使用する必要はない。それは、押さえ具4を固定するために頭付ボルト3の先端部分にねじ込まれるナット7が、押さえ具4と頭付ボルト3の両方を固定具2に固定するからである。すなわち、ナット7が押さえ具4を締め付けると、頭付ボルト3は頭部3Aがナット7に引っ張られて、連結溝2Aの開口部にしっかりとずれないように連結される。
【0024】
スペーサー5に開口しているボルト孔5aは、頭付ボルト3のネジ部3Bを挿通するので、頭付ボルト3の外径よりも大きい。スペーサー5は、ボルト孔5aを中間ナット8よりも大きく開口している。図10に示すスリット状のボルト孔5aは、スリット幅を中間ナット8の外径よりも大きくしている。このスペーサー5は、中間ナット8で固定具2に固定されない。太陽電池パネル1と固定具2とに挟着して固定される。この構造のスペーサー5は、太陽電池パネル1を仮り止めする状態、いいかえると、押さえ具4を固定するナット7を完全に締め込まない状態で、図8の矢印Aで示す方向に押圧し、あるいは叩き、鎖線で示す位置から実線で示す位置へ、すなわち、スペーサー5の端面カバー部5Bが固定具2の開口端面2aから離れた位置から、端面カバー部5Bを開口端面2aに当接させる位置まで移動できる。このとき、頭付ボルト3が鎖線で示すように、連結溝2Aの端部にあると、スペーサー5が頭付ボルト3を押して、実線で示す位置に移動させる。このため、スペーサー5を移動させて、頭付ボルト3を固定具2の所定の範囲に移動できる。ただ、スペーサー5を中間ナット8で固定具2に軽く固定している状態においても、スペーサー5を鎖線で示す位置から実線位置に移動できる。このため、スペーサーのボルト孔は、必ずしも中間ナットの外径よりも小さくする必要はない。ボルト孔は、頭付ボルトを挿通できて、中間ナットを通過できない大きさとすることもできる。この構造は、中間ナットが完全にスペーサーを固定具に固定しない状態として、スペーサーを鎖線位置から実線位置に移動させる。
【0025】
図10と図11に示すスペーサー5及びスペーサー5Mは、太陽電池パネル1のリード線を挿通する支持孔5bを設けている。リード線は、この支持孔5bに結束材で連結されて、移動しないように配線される。
【0026】
さらに、スペーサー5は、図12の側面図に示すように、上面カバー部5Aに端面カバー部5Bと位置決め凸部9とを設けて、位置決め凸部9と端面カバー部5Bとの間に固定具2を配置することもできる。
【0027】
また、図13に示す太陽電池装置は、太陽電池パネル1の前縁、すなわち屋根に固定する状態で特に目だつ下端縁を、前縁カバー10でカバーしている。前縁カバー10は、アルミニウムの引き抜き材、あるいはプラスチックを成形して製作され、断面形状が一様となっている。前縁カバー10は、屋根に固定して目だたないように、黒や焦げ茶等の暗色に着色している。前縁カバー10は、前面と上面とを後方に向かって上り勾配の傾斜面10Bとし、背面には、押さえ具4の係止部4Bに押圧されて固定される縦溝10Aを設けている。前縁カバー10は、固定具2の上に載せられ、縦溝10Aに押さえ具4の係止部4Bを入れて、押さえ具4で固定具2に固定される。この構造は、太陽電池パネル1を固定する押さえ具4で、前縁カバー10も固定できる。
【0028】
以上の構造の太陽電池装置は、以下の工程で屋根に固定される。
(1) 屋根の所定の位置に固定具2が固定される。固定具2は、止ビス6を介して屋根に固定される。ただ、本発明の太陽電池装置は、固定具2を屋根に固定する構造を特定するものではなく、固定具2を接着して屋根に固定し、あるいは接着と止ビス6の両方で屋根に固定することもできる。固定具2を所定の位置に固定するために、屋根に墨だしして、印を付け、墨出しされた印にしたがって、固定具2を屋根に固定する。本発明の太陽電池装置は、固定具2を固定する位置が多少ずれても、太陽電池パネル1を固定できるので、墨出しには高い精度が要求されない。
【0029】
(2) 固定具2の連結溝2Aに頭付ボルト3の頭部3Aを入れ、頭付ボルト3を中間ナット8で所定の位置に連結する。中間ナット8は、完全に頭付ボルト3を固定する必要はなく、頭付ボルト3を仮止めする程度でよい。
【0030】
(3) スペーサー5を固定具2に積層する。スペーサー5は、端面カバー部5Bが屋根の下側(=軒先側)となるように、固定具2にセットされる。さらに、スペーサー5は、ボルト孔5aに頭付ボルト3を入れて、固定具2の上にセットされる。
【0031】
(4) 太陽電池パネル1をスペーサー5の上に載せ、押さえ具4を頭付ボルト3のネジ部3Bに挿通し、押さえ具4の上にナット7をねじ込んで、太陽電池パネル1を仮止めする。このとき、押さえ具4を固定するナット7を、完全に締め付けせず、太陽電池パネル1を移動できるように軽く固定具2に仮止めする。太陽電池パネル1は、複数の固定具2と押さえ具4とナット7で固定具2に固定されるので、太陽電池パネル1を固定する全てのナット7を軽く締め付けする。
【0032】
その後、図8のように、太陽電池パネル1、スペーサー5が所定の位置であることを確認できたら、全てのナット7を完全に締め付けて、押さえ具4で太陽電池パネル1を移動しないように固定する。
また、太陽電池パネル1、スペーサー5が所定の位置でないときは、図8のように、鎖線の状態にあるスペーサー5を、軒下側から固定具2の軒下側の開口端面2aに向けて押すことより、スペーサー5のボルト孔5aが移動するので、頭付ボルト3が、固定具2の連結溝2Aの延在する方向における略中央に移動することになる。従って、頭付ボルト8が、図8の鎖線のように固定具2の軒下側の開口端面2a付近、固定具2の棟側の開口端部2a付近に位置することがなく、中央付近に位置させることができる。この状態で、全てのナット7を完全に締め付けて、押さえ具4で太陽電池パネル1を移動しないように固定する。
【0033】
(5) 図13と図14に示すように、前縁カバー10を固定する太陽電池装置は、太陽電池パネル1の前縁を固定する押さえ具4で前縁カバー10を固定する。
【0034】
【発明の効果】
本発明の太陽電池装置は、安価で短い固定具を使用して、簡単かつ容易に、しかもしっかりと太陽電池パネルを屋根に固定できる特長がある。それは、本発明の太陽電池装置が、屋根に固定される固定具と太陽電池パネルとの間にスペーサーを配設しており、このスペーサーに連結溝の全長よりも短いボルト孔を設けて、固定具に連結している頭付ボルトをボルト孔に挿通しており、この頭付ボルトを介して押さえ具で太陽電池パネルを固定具に連結しているからである。このように、固定具と太陽電池パネルとの間にスペーサーを挟着して、このスペーサーに設けたボルト孔に頭付ボルトを挿通する構造は、ボルト孔で頭付ボルトの移動を抑制して、頭付ボルトが固定具の端部に移動するのを有効に防止できる。したがって、本発明の太陽電池装置は、短くて安価な固定具を使用して、しっかりと太陽電池パネルを屋根に固定できる。
【0035】
さらに、本発明の太陽電池装置は、固定具と太陽電池パネルとの間に挟着されるスペーサーに、固定具の連結溝の開口端面をカバーする端面カバー部を設けているので、この端面カバー部で固定具の開口端面をカバーして、切断面が外部に表出するのを防止できる特長もある。このことは、固定具にアルミニウムの引き抜き材を使用して、固定具を短く切断しながら、切断面を端面カバー部でカバーして、屋根に適合する色彩として美しい外観とすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a solar cell device that fixes a solar cell panel to a roof.
[0002]
[Prior art]
Solar panels need to be firmly fixed to the roof. This is for fixing the solar cell panel so as not to move by a strong wind such as a typhoon. For the purpose of realizing this, structures for fixing a solar cell panel to a roof are described in References 1 and 2 below.
[0003]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 11-247487 [Patent Document 2]
JP-A-7-202242
The publication of Reference 1 describes a structure for fixing the solar cell panel 1 to the roof 11 with the structure shown in FIG. 1, and the publication of Reference 2 discloses that the solar cell panel 1 is attached to the roof 11 with the structure shown in FIG. Is described. In these solar cell devices, a fixing tool 2 fixed to a roof 11, a head bolt 3 connected to a connecting groove 2A of the fixing tool 2, and a head bolt 3 inserted through a through hole 4A. And a solar cell panel 1 that guides the locking portion 4B of the pressing member 4 to the slide groove 1A. In this solar cell device, the holding member 4 is connected to the fixing member 2 with a nut 7 screwed into the head bolt 3, and the solar cell panel 1 is connected to the fixing member 2 fixing the solar cell panel 1 to the roof 11 with the head bolt 3. are doing.
[0005]
[Problems to be solved by the invention]
The solar cell devices described in these publications have a drawback in that the fixing device fixed to the roof is elongated along the periphery of the solar cell panel, so that the fixing device becomes long. In addition, it is necessary to fix the fixture at an accurate position along the periphery of the solar cell panel. As a result of examination by the present applicant, as shown in FIGS. 3 and 4, which have not been released yet, the short fixture 2 is attached to the solar cell panel 1 on the roof in a posture intersecting with the periphery. It can be fixed and eliminated. (FIGS. 3 and 4 are schematic diagrams viewed from above to show the positional relationship between the solar cell panel 1 and the fixture 2). In this mounting structure, the headed bolt is perpendicular to the periphery of the solar cell panel. Since the retainer can be moved along the slide groove of the solar cell panel, the headed bolt can be moved in both the vertical and horizontal directions with respect to the periphery of the solar cell panel and fixed to the roof. Therefore, there is a feature that the fixture can be easily and efficiently fixed to the roof without accurately positioning the fixture. Also, since the fixture can be shortened, there is also a feature that the fixture can be inexpensive.
[0006]
However, when the solar cell panel is fixed to the roof with this structure, the head bolt may move to the end of the fixing tool and may not be fixed firmly. This is because the headed bolt can be freely moved along the connection groove 2A. Further, since the opening end face of the connecting groove 2A provided in the fixing tool 2 is exposed to the outside, for example, in the case of a fixing tool manufactured by cutting a colored aluminum drawn material into a predetermined length, the fixing tool is not colored. The cut surface is exposed to the outside. Since the cut surface of the metal is very different from the color of the roof, there is a disadvantage that this makes it impossible to make the roof beautifully colored.
[0007]
The present invention has been developed to solve such disadvantages. An important object of the present invention is to provide a solar cell device that can easily and easily and firmly fix a solar cell panel to a roof using an inexpensive and short fixing tool.
Another important object of the present invention is to provide a solar cell device that can be cut into a color that matches the roof by using a drawn-out member of aluminum for the fixture.
[0008]

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the following examples illustrate a solar cell device for embodying the technical idea of the present invention, and the present invention does not specify the solar cell device as follows.
[0012]
Further, in this specification, in order to make it easy to understand the claims, the numbers corresponding to the members shown in the embodiments are referred to as “claims” and “means for solving the problems”. Are added to the members indicated by "." However, the members described in the claims are not limited to the members of the embodiments.
[0013]
The solar cell device shown in FIGS. 5 to 10 has a fixture 2 fixed to a roof 11, a headed bolt 3 connecting a head 3A to the fixture 2, and the headed bolt 3 is passed through. A through-hole 4A is opened, and guides a holding member 4 connected to the fixture 2 via a headed bolt 3 inserted into the through-hole 4A and a locking portion 4B provided on the holding member 4. And a solar cell panel 1 having a sliding groove 1 </ b> A on its periphery.
[0014]
The fixture 2 is obtained by cutting a drawn aluminum material into a length of, for example, 5 cm to 20 cm, and has a connecting groove 2A at the center of the cross section and side grooves 2B on both sides. The fixture 2 is fixed to the roof 11 in a state where the direction in which the connecting groove 2A extends matches the inclination direction of the roof 11 (indicated by an arrow in FIG. 5). The opening of the connection groove 2A is narrowed to connect the head 3A of the headed bolt 3 so as not to come off. In the illustrated connection groove 2A, ribs projecting inward from each other are provided in the opening to narrow the opening. Although not shown, the opening of the connecting groove may be narrowed with the side surface facing the inclined surface. The connecting groove 2A extends to the end of the fixture 2 and opens at the end so that the head 3A of the headed bolt 3 can be guided from the opening of the connecting groove 2A. The head 3A has a size that cannot be rotated in the connection groove 2A.
[0015]
The side groove 2B has a U-shaped cross section. A circular stop hole 2b is opened in the bottom of the side groove 2B. The fixing holes 2b are provided at a plurality of positions of the fixing tool 2, and the fixing tool 2 is firmly fixed to the roof 11 with fixing screws 6 inserted therein. The fixture 2 shown has a plurality of stop holes 2b in each side groove 2B. The stop screw 6 screwed into the stop hole 2b has the head 6A inside the side groove 2B and does not protrude from the upper surface of the fixture 2. However, it is not always necessary to provide a side groove in the fixture. This is because the upper surface opening of the stopper hole is made thicker, and the head of the stopper screw is inserted into the thicker part, so that the head does not protrude from the surface of the fixing tool. The stop screw 6 is screwed into the roof material such as a roof plate or a tile of the roof 11 from the stop hole 2b, and fixes the fixture 2 to the roof 11 firmly.
[0016]
The fixture 2, which is a drawn aluminum material, is manufactured by coating and then cutting to a predetermined length. Since the connection groove 2A is cut after the coating, the opening end face 2a of the connection groove 2A has a metal surface of aluminum exposed. The upper surface, the lower surface, and both side surfaces are colored dark, such as black or dark brown, so as to be compatible with the roofing material. However, in the solar cell device of the present invention, the fixture does not necessarily need to be a drawn aluminum material. The fixture may be manufactured by pressing a metal plate such as iron, copper, or stainless steel, casting aluminum, or molding a weather-resistant plastic.
[0017]
As shown in FIG. 5, a solar cell device in which a plurality of solar cell panels 1 are fixed to a roof 11 has a fixing tool 2 that connects boundaries of the solar cell panels 1 in a direction in which a connecting groove 2 </ b> A extends. The two solar cell panels 1 can be firmly fixed using the elongated intermediate fixture 2M. FIG. 5 shows a process of installing the solar cell device, and the structure is the same as the positional relationship between the solar cell panel 1 and the fixture 2 in FIG. 4 described above. The long intermediate fixing tool 2M can increase the adjustment width of the fixing position of the adjacent solar cell panel 1 and, as shown in FIG. 11, can firmly fix the solar cell panel 1 to the roof with a large area using a large number of fixing screws 6. This intermediate fixture 2M can firmly fix two adjacent solar cell panels 1. However, as shown in FIG. 6 and FIG. 7, the intermediate fixture 2 </ b> M may use the same fixture 2 that fixes the outer peripheral edge of the solar cell panel 1 to fix the adjacent solar cell panel 1. it can. In addition, as can be seen in FIGS. 5 and 11, the plate-shaped spacer 5M is provided between the solar cell panel 1 and the intermediate fixture 2M. And such a fixing tool 2 can be used also in the arrangement position of FIG. 3 described above. In addition, in FIG. 3, the fixture 2 is also arranged such that the extending direction of the connecting groove 2 </ b> A intersects at right angles to the roof inclination direction (indicated by an arrow in FIG. 3). Each of such a fixture 2 and an intermediate fixture 2M is installed on a flat steel plate on a roof or on a single slate tile.
[0018]
The fixture 2 is fixed to the roof, preferably in an orthogonal posture, so that the connection groove 2A intersects the slide groove 1A of the solar cell panel 1. In particular, the fixing device 2 for fixing the lower edge of the solar cell panel 1 fixed to the lowermost stage is fixed such that the slide groove 1A and the connection groove 2A of the solar cell panel 1 intersect, preferably orthogonally. However, in the solar cell device of the present invention, it is not always necessary to fix all the fixing tools 2 in such a manner that the connecting grooves 2A are orthogonal to the slide grooves 1A of the solar cell panel 1. For example, the connecting grooves 2A of the fixing tools 2 are not required. Can be fixed so as to be in a posture parallel to the slide groove 1A. Since the fixing device 2 fixed in this state cannot move the position where the solar cell panel 1 is fixed in the direction orthogonal to the slide groove 1A, the solar cell panel 1 is first fixed and positioned by the fixing device 2. After that, it is preferable that the connecting groove 2A is fixed to the fixing tool 2 arranged in a direction crossing the slide groove 1A.
[0019]
The presser 4 is formed by pressing a metal plate such as stainless steel into a U-shaped cross section, and has locking portions 4B on both sides. As shown in the cross-sectional view of FIG. 9, the locking portions 4B on both sides have lower edges in an arch shape so that both ends are in point contact with the bottom of the slide groove 1A. The presser 4 presses the slide groove 1 </ b> A of the solar cell panel 1 at two points of the locking portion 4 </ b> B, and fixes it to the fixture 2. The presser 4 has a through hole 4 </ b> A through which the headed bolt 3 penetrates. The holding member 4 is fixed to the fixing member 2 by inserting the head bolt 3 into the through hole 4 </ b> A, screwing the nut 7 into the head bolt 3, and using the nut 7. The through hole 4A is provided at the center of the plane portion bent in a U-shape.
[0020]
The solar cell panel 1 has a panel-shaped main body having a structure in which a large number of plate-shaped solar cells 1B that receive light and generate power are sealed, and has a structure including an outer frame on an outer periphery thereof, and has a cross section along a peripheral edge. An L-shaped slide groove 1A is provided. The solar cell panel 1 is connected to a lead wire (not shown) for extracting power. The lead wires are wired on the lower surface of the solar cell panel 1 supported by the fixture 2, that is, between the solar cell panel 1 and the roof.
[0021]
Next, the spacer 5 which is a feature of the present invention will be described in detail.
The spacer 5 is manufactured by pressing a metal plate. The surface of the spacer 5 is colored dark, such as black or dark brown. The spacer 5 and the fixture 2 are preferably colored the same color, for example, black. The spacer 5 of the same color as the fixing tool 2 can cover the opening end face 2a of the fixing tool 2 so as not to be noticeable. The spacer does not necessarily need to be made of a metal plate, but can be made by molding a hard plastic. By using the spacers 5 and the spacers 5M, the height of the upper surfaces of the spacers 5 and the spacers 5M on the fixtures 2 provided on the slate roof tiles or the like can be adjusted by using a plurality of the spacers if necessary. It can be adjusted and the solar cell panel 1 can be stably installed.
[0022]
The spacer 5 has an L-shaped cross section as a whole, as shown in FIGS. The spacer 5 includes an upper surface cover portion 5A sandwiched between the fixing device 2 and the solar cell panel 1, and an end surface cover portion 5B that covers the opening end surface 2a of the connection groove 2A of the fixing device 2. The top cover 5A has a slit-shaped bolt hole 5a in order to arrange the headed bolt 3 to be inserted at a predetermined position. The bolt hole 5a is shorter than the entire length of the connecting groove 2A of the fixture 2, in other words, shorter than the entire length of the fixture 2. Since the slit-shaped bolt hole 5a can move the headed bolt 3 along the slit, the headed bolt 3 is fixed in a predetermined range while adjusting the position of the headed bolt 3. The bolt hole 5a does not necessarily need to be formed in a slit shape, and may be a round hole or a polygonal hole through which the headed bolt 3 can be inserted.
[0023]
In the illustrated solar cell device, the headed bolt 3 is fixed to the fixture 2 with an intermediate nut 8. That is, the intermediate nut 8 for fixing the headed bolt 3 to the fixture 2 and the nut 7 for fixing the holding member 4 are doubly screwed into the headed bolt 3. This mounting structure has a feature that the headed bolt 3 is fixed to the fixture 2 with the intermediate nut 8, and the holding member 4 can be fixed to the headed bolt 3. The intermediate nut 8 does not need to completely fix the headed bolt 3 to the fixture 2. This is because the nut 7 screwed into the head bolt 3 to fix the holding member 4 can be completely tightened, and the head bolt 3 can be fixed to the fixing member 2 so as not to move. Further, the intermediate nut 8 need not always be used. This is because the nut 7 screwed into the tip of the headed bolt 3 to fix the holder 4 fixes both the holder 4 and the headed bolt 3 to the fixture 2. That is, when the nut 7 tightens the holding member 4, the head bolt 3A is pulled by the nut 7 so that the head bolt 3 is connected to the opening of the connection groove 2A so as not to be firmly displaced.
[0024]
The bolt hole 5 a opened in the spacer 5 is larger than the outer diameter of the headed bolt 3 because the screw portion 3 </ b> B of the headed bolt 3 is inserted therethrough. The spacer 5 has a bolt hole 5 a that is larger than the intermediate nut 8. The slit-shaped bolt hole 5 a shown in FIG. 10 has a slit width larger than the outer diameter of the intermediate nut 8. This spacer 5 is not fixed to the fixture 2 by the intermediate nut 8. It is sandwiched and fixed between the solar cell panel 1 and the fixture 2. The spacer 5 having this structure is pressed in the direction shown by the arrow A in FIG. 8 in a state where the solar cell panel 1 is temporarily fixed, in other words, in a state where the nut 7 for fixing the presser 4 is not completely tightened. Tapping, from the position shown by the chain line to the position shown by the solid line, that is, from the position where the end face cover 5B of the spacer 5 is separated from the opening end face 2a of the fixture 2, to the position where the end face cover 5B abuts on the opening end face 2a. You can move. At this time, when the headed bolt 3 is at the end of the connection groove 2A as shown by the chain line, the spacer 5 pushes the headed bolt 3 to move it to the position shown by the solid line. For this reason, the headed bolt 3 can be moved to a predetermined range of the fixture 2 by moving the spacer 5. However, even in a state where the spacer 5 is lightly fixed to the fixture 2 with the intermediate nut 8, the spacer 5 can be moved from the position indicated by the chain line to the position indicated by the solid line. For this reason, the bolt hole of the spacer does not necessarily need to be smaller than the outer diameter of the intermediate nut. The bolt hole can be sized so that the headed bolt can be inserted and cannot pass through the intermediate nut. This structure moves the spacer from the dashed line position to the solid line position, with the intermediate nut not completely securing the spacer to the fixture.
[0025]
The spacer 5 and the spacer 5M shown in FIGS. 10 and 11 are provided with a support hole 5b through which the lead wire of the solar cell panel 1 is inserted. The lead wire is connected to the support hole 5b with a binding material and wired so as not to move.
[0026]
Further, as shown in the side view of FIG. 12, the spacer 5 is provided with an end face cover 5B and a positioning protrusion 9 on the upper surface cover 5A, and a fixing tool is provided between the positioning protrusion 9 and the end face cover 5B. 2 can also be arranged.
[0027]
Further, in the solar cell device shown in FIG. 13, the front edge of the solar cell panel 1, that is, the lower edge particularly prominent when fixed to the roof, is covered with the front edge cover 10. The leading edge cover 10 is manufactured by molding a drawn aluminum material or plastic, and has a uniform cross-sectional shape. The front edge cover 10 is colored dark, such as black or dark brown, so as to be fixed to the roof and not stand out. The front edge cover 10 has a front surface and an upper surface formed as an inclined surface 10B having an upward slope toward the rear, and a rear surface provided with a vertical groove 10A which is pressed and fixed by the locking portion 4B of the holding member 4. The front edge cover 10 is placed on the fixing tool 2, the locking portion 4 </ b> B of the pressing tool 4 is inserted into the vertical groove 10 </ b> A, and is fixed to the fixing tool 2 with the pressing tool 4. In this structure, the front edge cover 10 can also be fixed by the holding member 4 for fixing the solar cell panel 1.
[0028]
The solar cell device having the above structure is fixed to the roof in the following steps.
(1) The fixture 2 is fixed at a predetermined position on the roof. The fixing tool 2 is fixed to the roof via a retaining screw 6. However, the solar cell device of the present invention does not specify the structure for fixing the fixing tool 2 to the roof, but fixes the fixing tool 2 to the roof by bonding, or fixes the fixing tool 2 to the roof using both the adhesive and the fixing screw 6. You can also. In order to fix the fixing device 2 at a predetermined position, the roof is inked and marked, and the fixing device 2 is fixed to the roof according to the marked mark. The solar cell device of the present invention can fix the solar cell panel 1 even if the position for fixing the fixing tool 2 is slightly shifted, so that high accuracy is not required for blackout.
[0029]
(2) The head 3A of the head bolt 3 is inserted into the connection groove 2A of the fixture 2, and the head bolt 3 is connected to a predetermined position with the intermediate nut 8. The intermediate nut 8 does not need to completely fix the headed bolt 3, but only needs to temporarily fix the headed bolt 3.
[0030]
(3) The spacer 5 is laminated on the fixture 2. The spacer 5 is set on the fixture 2 such that the end face cover 5B is located below the roof (= eave side). Further, the spacer 5 is set on the fixture 2 by inserting the headed bolt 3 into the bolt hole 5a.
[0031]
(4) The solar cell panel 1 is placed on the spacer 5, the holding member 4 is inserted into the screw portion 3 </ b> B of the headed bolt 3, and the nut 7 is screwed on the holding member 4 to temporarily fix the solar cell panel 1. I do. At this time, the nut 7 for fixing the holding member 4 is not completely tightened, but is temporarily fixed to the fixing member 2 lightly so that the solar cell panel 1 can be moved. Since the solar cell panel 1 is fixed to the fixing tool 2 with the plurality of fixing tools 2, the holding tools 4 and the nuts 7, all the nuts 7 fixing the solar cell panel 1 are lightly tightened.
[0032]
Thereafter, as shown in FIG. 8, when it is confirmed that the solar cell panel 1 and the spacer 5 are at predetermined positions, all the nuts 7 are completely tightened so that the holding member 4 does not move the solar cell panel 1. Fix it.
When the solar cell panel 1 and the spacer 5 are not at the predetermined positions, as shown in FIG. 8, the spacer 5 in the state of the chain line is pushed from the underside of the eaves toward the opening end face 2 a on the underside of the fixture 2. Since the bolt hole 5a of the spacer 5 moves, the headed bolt 3 moves to substantially the center in the direction in which the connecting groove 2A of the fixing tool 2 extends. Therefore, the headed bolt 8 is not located near the opening end face 2a below the eaves of the fixture 2 or near the ridge-side opening end 2a of the fixture 2 as shown by the chain line in FIG. Can be done. In this state, all the nuts 7 are completely tightened, and the holding member 4 fixes the solar cell panel 1 so as not to move.
[0033]
(5) As shown in FIGS. 13 and 14, in the solar cell device for fixing the front edge cover 10, the front edge cover 10 is fixed by the holding member 4 for fixing the front edge of the solar cell panel 1.
[0034]
【The invention's effect】
The solar cell device according to the present invention has a feature that the solar cell panel can be easily and easily and firmly fixed to the roof by using an inexpensive and short fixing tool. That is, in the solar cell device of the present invention, a spacer is provided between the fixing device fixed to the roof and the solar cell panel, and a bolt hole shorter than the entire length of the connecting groove is provided in the spacer to fix the spacer. This is because the head bolt connected to the fixture is inserted into the bolt hole, and the solar cell panel is connected to the fixture with the holding tool via the head bolt. Thus, the structure in which the spacer is sandwiched between the fixture and the solar cell panel, and the headed bolt is inserted into the bolt hole provided in the spacer, the movement of the headed bolt is suppressed by the bolt hole.
