Description

【０００１】
【発明の属する技術分野】本発明は、平板状の太陽電池板等を屋根に取り付ける枠部材に関する。
【０００２】
【従来の技術】従来の太陽電池板取り付け用枠部材は、例えば、図１１に示すように、基礎枠部材１にボルト６とナット７で載置固定される両側にコの字状の係止部３１１をもつ枠本体３００と蓋部材３１２とからなる。太陽電池板２００はその側端部が係止部３１１に挿入されて取り付けられる。
【０００３】
【発明が解決しようとする課題】しかしながら、上記従来の枠部材は、形状が複雑で、ロール成形等で作ることができず高価である。また、厚さが異なる太陽電池板毎に係止部の寸法が異なるため、太陽電池板のメーカ毎に係止部寸法の異なる枠本体が必要になるといった問題があった。
【０００４】本発明は上記従来の枠部材の問題に鑑みてなされたものであり、厚さが異なる太陽電池板を取り付けることができるフレキシブルな枠部材を提供することを目的とする。
【０００５】本発明の別の目的は、ロール成形などで簡単に製造することができる枠本体からなる枠部材を提供することである。
【０００６】
【課題を解決するための手段】本発明の太陽電池板取り付け用枠部材は、屋根上に固定された架台の一部を形成する互いに間隔を隔てて設けられた複数個の基礎枠部材に載置固定され、背向する左右両側面に係止片をもつ平板状の太陽電池板を屋根に取り付ける太陽電池板取り付け用枠部材であって、断面形状で、前記基礎枠部材の上面に固定される所定幅の基底部と、該基底部の両端側にそれぞれ一体的に形成され上方に延びる所定高さの一対の立壁部と、各該立壁部の上端に一体的に形成され該基底部と平行に先端が互いに近づくように延び両先端間に所定幅の中央開口を区画する一対の縁部とを有する枠本体と、それぞれ該縁部の下端面に当接する係合片を両側部の下方にもち、かつ中央部に係止穴をもつ該中央開口より上方に所定高さ立ち上がる係合駒と、該太陽電池板の側端部の下面が該枠本体の該縁部の上面に当接されて載置された該太陽電池板の該係止片と係止する係止側端部をもつ長尺状の押さえ部と、該押さえ部と該枠本体の該中央開口より立ち上がる該係合駒の該係止穴に係止され該押さえ部と該枠本体の該縁部とで該太陽電池板の該側端部を挟持する係止部材と、をもつ。
【０００７】押さえ部と枠本体の中央開口より立ち上がる係合駒の係止穴に係止される係止部材で、押さえ部と枠本体の縁部とで挟持される太陽電池板の側端部を係止するので、厚みの異なる太陽電池板を取り付けることができる。
【０００８】枠本体は、さらに、基底部の両端側にそれぞれ一体的に形成され該基底部と平行に延びる鍔部をもつものとすることができる。
【０００９】枠部材の基礎枠部材への固定は、鍔部が無いと、枠本体の基底部と基礎枠部材をボルトなどで固定する必要がある。その際、ボルトを枠本体の中央開口から導入する必要があり、作業性が悪い。鍔部があると、鍔部と基礎枠部材をねじ釘や押さえ金具とボルトなどを使って固定することができるので、固定の作業性がよい。
【００１０】係合駒は、さらに、両側部の上方に枠本体の縁部の上面に当接載置される太陽電池板の側端面と当接して位置決めする突き出し部をもつものとすることができる。
【００１１】太陽電池板には係止片を上方にもつものと、下方にもつものがあるが、係合駒が両側部の上方に突き出し部をもつので、太陽電池板が係止片を上方にもつ場合でも、太陽電池板の側端面が突き出し部に当接して位置決めされる。
【００１２】さらに、係合駒はその両側部の下方に枠本体の縁部と嵌合される凹部をもつものとすることができる。
【００１３】係合駒が凹部で枠本体の縁部と嵌合されるので、枠本体に係合駒を取り付ける際、係合駒が落ち込むことが無く、枠本体の長手方向に移動することができ、作業性がよくなる。
【００１４】枠本体は、さらに、各縁部の端部からそれぞれ一体的に上方に延びる所定高さの第２立壁部と各第２立壁部の上端よりそれぞれ互いに背向するように反対側に延び、縁部の上面に当接載置される太陽電池板の側端面と当接して位置決めする衝突縁部をもつものとすることができる。
【００１５】枠本体が衝突縁部をもつので、太陽電池板が係止片を上方にもつ場合でも、太陽電池板の側端面が衝突縁部に当接して位置決めされる。
【００１６】係合駒は、さらに、その両側部の下端に下方に延びて枠本体の基底部に当接する爪部をもつものとすること、あるいは、さらに、各係合片の両端側にそれぞれ一体的に形成され下方に延びて枠本体の基底部に当接する脚部をもつものとすることもできる。
【００１７】係合駒の爪部あるいは脚部が、枠本体の基底部に当接するで、枠本体に係合駒を取り付ける際、係合駒が落ち込むことが無く、枠本体の長手方向に移動することができ、作業性がよくなる。
【００１８】また、押さえ部は係止側端部を複数もつものとすることができる。
【００１９】複数の係止側端部が太陽電池板の係止片と咬合するので太陽電池板を確実に取り付けることができる。
【００２０】押さえ部は、左右の一端部に太陽電池板の係止片と係止する係止側端部をもち、他端部に下方に延びる垂直片をもち、その垂直片の途中に突起座が内側に向けて形成されているものとすることができる。
【００２１】突起座が枠本体の衝突縁部とあるいは係合駒の突き出し部と当接するので、片側に太陽電池板を取り付ける場合でも確実に係止することができる。
【００２２】また、枠部材は、さらに、押さえ部の垂直片の内側に一端を接し、他端を外側に向け略直角に曲げた後下方に略直角に曲げた、枠本体及び係合駒を覆う長尺状のカバーを有するものとすることができる。
【００２３】カバーを有するので、太陽電池板取り付け端面部の雨じまいと美観を良くすることができる。
【００２４】枠部材は、さらに、枠本体の基底部と基礎枠部材の間に挟持される断面がＬ字状のトレーを有するものとすることができる。
【００２５】トレーと枠本体の立壁部との間に形成される空間を太陽電池板の出力ケーブル収納スペースとすることで、従来垂れ下がりがちなケーブルの収納を容易に且つ安定して行うことができる。
【００２６】押さえ部は中央部に貫通穴をもち、係止部材は、該貫通穴に挿入されるボルトであり、係合駒の係止穴を該ボルトのねじ穴とすることもできる。
【００２７】押さえ部の貫通穴からボルトを挿入して係合駒のねじ穴にねじ込むことで、押さえ部と枠本体の縁部とで太陽電池板の側端部を容易に狭持することができる。
【００２８】また、係合駒は、係合片と中央部をもち、該中央部の中央に貫通する係止穴をもつ駒本体と、該駒本体の該係止穴に挿着された中央凸部をもつナットとからなるようにすることもできる。
【００２９】駒本体の係止穴をねじ穴にする必要が無く、駒本体を薄板材で一体成形することができる。
【００３０】
【発明の実施の形態】枠本体は、基礎枠部材の上面に固定される所定幅の基底部と、その基底部の両端側にそれぞれ一体的に形成され上方に延びる所定高さの一対の立壁部と、各立壁部の上端に一体的に形成され基底部と平行に先端が互いに近づくように延び両先端間に所定幅の中央開口を区画する一対の縁部とを有する。
【００３１】この枠本体は、長尺の箱形材の上面中央を所定幅切り取ることによって製作される。長尺の板材をロール成形等で成形することでも製作される。
【００３２】基底部は、通常Ｍ１０前後のボルトとナットで基礎枠部材に固定されるが、ねじ釘で固定される方が好ましい。ボルトとナットで固定する場合は基礎枠部材と基底部にバカ穴をあけて、その穴の位置を一致させてボルトを挿入する必要があるのに対して、ねじ釘で固定する場合は、位置合わせなどが不要で作業性がよい。ねじ釘で固定する場合、基礎枠部材と枠本体の基底部との間に両面粘着ゴムシートを介在させるとよい。枠本体の基礎枠部材への固定をより確実に行うことができる。
【００３３】太陽電池板のケーブルの収納と取り回しを確実にするための枠本体の基底部と基礎枠部材の間に挟持される断面がＬ字状のトレーの代わりに、基底部にケーブル挿入穴をあけて、ケーブルを枠本体の中に収納するようにしてもよい。
【００３４】中央開口の所定幅は、前記Ｍ１０前後のボルトが挿入できる必要があり、２５ｍｍ程度に設定されるとよい。
【００３５】枠本体は、さらに、各縁部の端部からそれぞれ一体的に上方に延びる所定高さの第２立壁部と各第２立壁部の上端よりそれぞれ互いに背向するように反対側に延び、縁部の上面に当接載置される太陽電池板の側端面と当接して位置決めする衝突縁部を持つものとすることができる。
【００３６】この枠本体は、長尺の凸形材の上部を切断して第２立壁部とし、その第２立壁部の上端を外側に曲げて衝突縁部とするように製作される。あるいは、この枠本体も長尺の板材をロール成形等で成形することで製作してもよい。
【００３７】第２立壁部の所定高さは、衝突縁部が太陽電池板の係止片が下方にある場合は係止片の上になるように、係止片が上方にある場合は係止片の下になるように設定され、且つ、衝突縁部の延び長さは、係止片の突き出し長さより短く設定される。このように設定されるので、太陽電池板が係止片を下方にもつ場合は、係止片の端部が第２立壁部に当接して位置決めされ、太陽電池板が係止片を上方に持つ場合は、太陽電池板の側端面が衝突縁部に当接して位置決めされる。
【００３８】枠本体は、さらに、基底部の両端側にそれぞれ一体的に形成され該基底部と平行に延びる鍔部をもつものとすることができる。
【００３９】この枠本体も長尺の板材をロール成形等で成形することで製作される。
【００４０】係合駒は、枠本体の縁部の下端面に当接する係合片を両側部の下方に有し、枠本体の中央開口より所定高さ立ち上がる両側部の上方に係止穴を持つ上面を有する。
【００４１】係止穴は、通常Ｍ８前後のボルトを係止するねじ穴が好ましい。バカ穴では、ナットを必要とし、作業性が悪くなる。
【００４２】係合駒は、係合片と中央部をもち、その中央部の中央に貫通する係止穴をもつ駒本体と、該駒本体の該係止穴に挿着された中央凸部をもつナットとからなるようにしてもよい。
【００４３】係合駒は、さらに、両側部の上方に枠本体の縁部の上面に当接載置される太陽電池板の側端面と当接して位置決めする突き出し部を持つものとすることができる。
【００４４】枠本体の中央開口より立ち上がる所定高さは、突き出し部が太陽電池板の係止片が下方にある場合は係止片の上になるように、係止片が上方にある場合は係止片の下になるように設定され、且つ、突き出し部の突き出し長さは、係止片の突き出し長さより短く設定される。このように設定されるので、太陽電池板が係止片を下方にもつ場合は、係止片の端部が両側部に当接して位置決めされ、太陽電池板が係止片を上方に持つ場合は、太陽電池板の側端面が突き出し部に当接して位置決めされる。
【００４５】突き出し部は、両側部の上方の係止穴をもつ上面の側端部に形成されることが好ましい。前記所定高さの設定がし易くなる。
【００４６】係合駒は、板材を展開図に切断し、上面と両側部の付け根部でコの字状に曲げることで作られる。
【００４７】長尺状の押さえ部は、長手方向に一定間隔でバカ穴をもつようにするとよい。このバカ穴に係止部材としてのボルトを挿入して、ボルトの下端を係合駒の係止穴に係止することで、容易に厚さの異なる太陽電池板を取り付けることができる。また、このバカ穴は、長手方向に長い長穴が好ましい。係合駒の係止穴との位置合わせが容易になり作業性が向上する。
【００４８】本発明の枠部材は、屋根上に設置され雨ざらしされるので、防錆に優れたステンレス材で製作されることが好ましい。
【００４９】
【実施例】実施例１．図１は本発明の一実施例の枠部材の正面図、図２は同じくその部分斜視図、図３は同じくその部分展開図である。
【００５０】本実施例の太陽電池板取り付け用枠部材３は、厚さが３０〜５０ｍｍの範囲にある太陽電池板を取り付けるように設定されたもので、図１、図２に示すように、基礎枠部材１の上面に固定される幅６５ｍｍの基底部１１と、その基底部１１の両端側にそれぞれ一体的に形成され上方に延びる高さ１５ｍｍの一対の立壁部１２と、各立壁部１２の上端に一体的に形成され基底部１１と平行に先端が互いに近づくように延び両先端間に幅２５ｍｍの中央開口を区画する一対の縁部１３とを持つ枠本体１０と、それぞれ縁部１３の下端面に当接する係合片２１を両側部の下方に持ち、かつ中央開口より上方に高さ２７ｍｍ立ち上がった上面の中央部にＭ８の係止ねじ穴２２を持つ係合駒２０と、太陽電池板２の側端部の下面が枠本体１０の縁部１３の上面に当接されて載置された太陽電池板２の係止片２８と係止する長さ３６ｍｍの係止側端部３１と長手方向に一定間隔に開けられたＭ８ボルトを挿入する貫通穴３２とを持つ長尺状の押さえ部３０と、押さえ部３０と枠本体１０の中央開口より立ち上がる係合駒２０の係止ねじ穴２２に係止され押さえ部３０と枠本体１０の縁部１３とで太陽電池板２の側端部を挟持する係止部材としてのＭ８のボルト４０と、を有する。
【００５１】本実施例の枠部材３は、上記のように、太陽電池板２を枠本体１０と押さえ部３０で挟持するので、厚みの異なる太陽電池板を取り付けることができる。
【００５２】また、本実施例の枠部材３は、枠本体１０の基底部１１と基礎枠部材１の間に挟持される断面がＬ字状のトレー１１０を有し、トレー１１０と枠本体１０の立壁部１２との間に形成される空間を太陽電池板２の出力ケーブル２９の収納スペースとしている。これにより、従来垂れ下がりがちなケーブルの収納を容易に且つ安定して行うことができる。
【００５３】係合駒２０は、中央開口より２７ｍｍ立ち上がった上面の側端部に枠本体１０の縁部１３の上面に当接載置される太陽電池板２の側端面と当接して位置決めする突き出し部２３を持っており、その突き出し部２３の突き出し長さが５ｍｍと係止片の突き出し長さ１０ｍｍより短く設定されているので、太陽電池板２が係止片２８を下方にもつ場合は、図１のように、係止片２８の端部が係合駒２０の両側部に当接して位置決めされ、押さえ部３０の係止側端部３１が、係合駒２０の突き出し部２３と太陽電池板２の側端面の間を通り係止片２８と係止する。太陽電池板２が係止片２８を上方に持つ場合は、係止側端部３１の短い押さえ部３０を用いることで、太陽電池板２の側端面が係合駒２０の突き出し部２３に当接して位置決めされる。
【００５４】係合駒２０は、さらに、両側部の下方に枠本体１０の縁部１３と嵌合される凹部２４をもつ。これにより、枠本体１０に係合駒２０を取り付ける際、係合駒２０が落ち込むことが無く、枠本体１０の長手方向に移動することができ、作業性がよくなる。
【００５５】枠本体１０は断面形状が単純なため、長尺の板材を例えばロール成形することで簡単に安く作製することができ、係合駒２０も図３に示すように、一枚の板材をレーザ切断等で展開図形に切り出し、点線で直角に曲げ加工することで簡単に作製することができる。
【００５６】実施例２．図４は、本発明の実施例２の枠部材３’の正面図、図５は同じくその部分斜視図である。本実施例の枠本体６０は、実施例１の枠本体１０の一態様であって、各縁部６３の端部からそれぞれ一体的に上方に延びる高さ２７ｍｍの第２立壁部６４と各第２立壁部６４の上端よりそれぞれ互いに背向するように反対側に５ｍｍ延び、縁部６３の上面に当接載置される太陽電池板２’の側端面と当接して位置決めする衝突縁部６５を持つ。
【００５７】係合駒７０も実施例１の係合駒２０の一態様であって、枠本体６０の中央開口より１７ｍｍ立ち上がった上面の中央部にＭ８の係止ねじ穴７２を、両側部に縁部６３の下端面に当接する係合片７１を、それぞれ持ち、さらに、両側部の下端に下方に延びて枠本体６０の基底部６１に当接する爪部７５を持つ。
【００５８】本実施例では、係合駒７０の係止ねじ穴７２を持つ上面の高さが１７ｍｍであるのに対して、枠本体６０の衝突縁部６５の高さが２７ｍｍであり、衝突縁部６５の突き出し長さが５ｍｍと係止片の突き出し長さ７ｍｍより短く設定されているので、太陽電池板２’が係止片２８’を下方にもつ場合は、係止片２８’の端部が第２立壁部６４に当接して位置決めされ、押さえ部８０の図示しない長い係止側端部８１が、衝突縁部６５と太陽電池板２’の側端面の間を通り係止片２８’を係止する。太陽電池板２’が図４に示すように、係止片２８’を上方に持つ場合は、太陽電池板２’の側端面が衝突縁部６５に当接して位置決めされる。
【００５９】係合駒７０は、爪部７５を持つので、枠本体６０に係合駒７０を取り付ける際、係合駒７０が落ち込むことが無く、枠本体６０の長手方向に移動することができ、作業性がよくなる。
【００６０】押さえ部８０も実施例１の押さえ部３０の一態様であって、両側部に各々二つの長さ５ｍｍの係止側端部８１を持ち、太陽電池板２’の係止片２８’と咬合している。これにより、太陽電池板２’が枠部材３から外れることが無く、太陽電池板の取付がより確実になる。
【００６１】実施例３．図６は、本発明の実施例３の枠部材３”の正面図である。本実施例の枠部材３”は、実施例２の枠部材３’と同じで、取り付けられる太陽電池板が異なるだけである。すなわち、太陽電池板２”は上方に係止片２８”を持つが、この係止片２８”は図６に示すように、突き出し長さが１２ｍｍと長く、実施例２の係止片２８’と異なる。係止片２８”が長く突き出していても、押さえ部８０が両側部に各々二つの係止側端部８１を持っているので、その係止側端部８１が係止片２８”と咬合して太陽電池板２”を確実に取り付けることができる。
【００６２】実施例４．図７は、本発明の実施例４の枠部材３４の正面図、図８は同じくその部分斜視図、図９は同じくその部分断面図である。
【００６３】本実施例の枠本体６０’は、実施例３の枠本体６０の一態様であって、基底部６１の両端側に基底部６１と平行な鍔部６６をもち、金具１２０とねじ釘１２１とで基礎枠部材１に固定されている。
【００６４】係合駒７０’も実施例３の係合駒７０の一態様であって、枠本体６０’の中央開口より立ち上がった中央部の中央には貫通する係止穴７２’を、両側部には縁部６３の下端面に当接する係合片７１’を、それぞれもち、さらに、その係合片７１’の両端側に、下方に延びて架台本体６０’の基底部６１に当接する脚部７６をもつ駒本体７０１と、係止穴７２’に挿着された中央凸部７７をもつナット７０２とからなる。
【００６５】本実施例では架台本体６０’の基礎枠部材１への取付を鍔部６６を介して外側から行うことができるので、鍔部のない基礎枠部材の取付より作業性がよい。また、駒本体７０１の係止穴７２’には凸部７７をもつナット７０２が挿着されているので、押さえ部８０の貫通穴８２から挿入される係止部材としてのボルト９０を螺合し易い。
【００６６】実施例５．図１０は、本発明の実施例５の枠部材３３の正面図、図１１は同じくその部分斜視図、図１２は同じくその部分平面図である。本実施例の枠部材３３は、実施例２の枠本体６０及び係合駒７０と、左右の一端部に太陽電池板２’の係止片２８’と係止する長さ５ｍｍの係止側端部８１’をもち、他端部に下方に延びる垂直片８２’をもち、その垂直片８２’の途中に枠本体６０の衝突縁部６５に当接する突起座８３’が内側に向けて形成されている押さえ部８０’と、押さえ部８０’の垂直片８２’の内側に一端を接し、他端を外側に向け略直角に曲げた後下方に略直角に曲げた、枠本体６０と係合駒７０を覆う長尺状のカバー１００と、を有している。枠本体６２の基底部６１の下面と基礎枠部材１’の上面との間には、両面粘着シート１３０が介挿され、ねじ釘１２１’で枠本体６０が基礎枠部材１’に固定されている。枠本体６０の基底部６１にはケーブル挿入穴６７が所定間隔であけられており、その挿入穴６７には基底部６１の下面に接着された片面粘着シート１３１のイで切り抜かれロで折り曲げられたリップが挿入されている。そして、その挿入穴６７を介して太陽電池板２’の出力ケーブル２９’が枠本体６０の中に収納され取り回されている。
