【発明の属する技術分野】
本発明は、太陽電池付屋根瓦に関する。
【0002】
【従来の技術】
従来、住宅等の屋根に太陽電池を設置し、太陽光線の持つエネルギーを利用し、本来の電力消費を補って、消費電力を節約するための太陽電池の応用方法が種々考案されている。
上記のような太陽電池が応用された例としては、例えば、特開平4−28524号公報や特開平8−144440号公報に記載された太陽電池瓦等が挙げられる。
【0003】
上記前者の特開平4−28524号公報に記載された例は、屋根瓦の表面に太陽電池を受容し得る浅い凹部を設け、この凹部に表面を突出させて太陽電池を収納したものである。
【0004】
又、後者の特開平8−144440号公報に記載された太陽電池瓦は、セメント瓦基板上の段差部に、太陽電池がフレーム体に支持されて接着固定又は金具固定されたものである。
【0005】
【発明が解決しようとする課題】
しかしながら、上記前者の特開平4−28524号公報に記載された例の場合においては、瓦の上面より太陽電池が突出して設けられているため、この突出部に塵埃等が付着するといった問題がある。
【0006】
又、この瓦が葺設された状態では、太陽電池の突出状態が目立って、屋根の外観意匠上見栄えがよくないといった問題がある。
更に、施工時の人の載る荷重や、飛来物等の衝撃荷重を突出した太陽電池が最も受け易い構造となっているので、破損や強度上の問題が懸念される。
【0007】
又、後者の特開平8−144440号公報に記載された太陽電池瓦においては、この瓦が葺設された状態では、瓦の基板部が重ね合わされて、殆ど裏側に埋没されるので、上面が殆ど太陽電池で占有された状態となり、瓦の葺設工事に際して、屋根上に別途に歩行のための通路を確保する必要が生じるといった問題がある。
【0008】
本発明は、このような上記の問題点に着目してなされたものであり、その目的とするところは、これらの問題点を解消し、屋根の外観意匠性が優れ、上面に塵埃等が付着せず、葺設時の作業性がよく、又、上からの荷重による破損の危険性や強度上の問題がない太陽電池付屋根瓦を提供するものである。
【0009】
【課題を解決するための手段】

又、葺設後の外観意匠性がよいものとすることができる。
【0013】
且つ、葺設状態において、上記突出周縁の突き合わされた合計幅が、歩行可能な幅に形成されることにより、葺設作業時に太陽電池を避けて突出周縁に載って作業が行え、従来の屋根瓦と同等の作業性が確保され、作業効率を向上させることができる。
又、万が一太陽電池上に足がかかっても、その荷重の大部分は平瓦の突出周縁により負担されるので、太陽電池の損傷を防止することができる。
【0014】
更に、上記突出周縁と太陽電池との境界は段差があっても、雨水の流れ方向と一致しているので、常に雨水により流されるので塵埃等が付着する心配がない。
【0015】
請求項2記載の本発明の太陽電池付屋根瓦においては、葺設状態において、上記突出周縁の突き合わされた合計幅が、4〜15cmと十分な幅が確保されているので、太陽電池を避けて、作業者が懸念なく突出周縁に載って作業することが可能である。
【0016】
請求項3記載の本発明の太陽電池付屋根瓦においては、突出周縁の太陽電池の上面よりの突出高さが1〜5mmとなっているので、万が一太陽電池上に足がかかっても、その荷重の大部分を突出周縁により負担させることが可能で、太陽電池の損傷を防止することができる。
又、一方突出周縁の太陽電池の上面よりの突出高さが1〜5mmと少なく、段差が小さいので、屋根の外観意匠性が損なわれるようなことがなく、見栄えがよいものとすることができる。
【0017】
