Description

【0001】
【発明の属する技術分野】
本発明は、太陽熱を配管に集中させて、管内を流通する液体を温める装置において、その組み立てが簡単にでき、施工効率を向上させることができる太陽光反射装置に関する。
【0002】
【従来の技術】
従来より、太陽エネルギ、特に太陽光を利用した装置が種々開発されている。その太陽光により加熱するための装置は、特に多く開発され、利用されている。これらのなかで、太陽光を一点に集中させて、特定のものを加熱する装置が種々存在し、さらに管を設け、管内に液体を流通させつつ、管とともに内部の液体を加熱しようとするものが存在する。これらは、適宜の形状に湾曲させた反射板を管の周囲に配置し、その反射板に太陽光が反射して管に集中し易いようにしている。
【0003】
この種の太陽光反射装置では、その施工において、反射板の形状が太陽光を一点に集中させやすいようにするために、特殊な形状に形成されていることが多く、例えばインボリュート曲線や放物線等を適宜に織りまぜられた形状となっている。そのために、反射板を支持するスタンドもその形状を維持するようにするために、専用のものが使用されている。
【0004】
【特許文献1】
特開2001−221513
【0005】
【発明が解決しようとする課題】
ところで上記特許文献1では、部品の点数が多く施工工程が多く、そのために熟練した技術が必要であり、作業が面倒である。しかもスタンドは、反射板の形状を正確に保持しつつ、所定位置に設置することが必要である。しかし、スタンドと反射板とをボルト及びナット等の固着具を使用して、施工する場合に、現場で反射板に孔開け加工等が必要となり、その際に、反射板に傷を付けてしまうおそれもある。
【0006】
さらに反射板は長手方向に長尺な材質の場合には、その加工箇所も多くなり、一層面倒な施工となる。このように、反射板とスタンドとの組み立て構造は極めて複雑なものとなり、またその施工も困難且つ面倒となる。本発明の目的は、太陽光反射装置の施工の困難性を解決し、効率の良い施工を行うことにある。
【0007】
【課題を解決するための手段】
そこで、発明者は、上記課題を解決すべく鋭意,研究を重ねた結果、本発明を、断面左右対称且つ略W字形状に形成され,それぞれがインボリュート曲面に形成された反射本体部の長手方向に沿って適宜の間隔をおいて固定部挿入孔及び被係止貫通孔が形成された反射部材と、該反射部材の裏面側をその形状に沿って当接状態に支持する支持部と前記反射部材の固定部挿入孔に挿通して前記反射本体部の表面上に突出する固定部とを有する受け台と、前記反射部材上に架設される管部材とからなり、該管部材は前記固定部により反射本体部上に固定されると共に、前記反射部材の被係止貫通孔に前記係止部が挿入されて、該係止部は折り曲げ,捩じり変形又は嵌合にて前記反射部材は受け台に固定されてなることを特徴とする太陽光反射装置としたことにより、極めて簡易且つ迅速に太陽光反射装置を施工することができ、上記課題を解決したものである。
【0008】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて説明する。本発明は、主に、反射部材Aと、受け台Bと、管部材10及びフレームC等から構成されている。まず、前記反射部材Aは、図1(B),図2等に示すように、反射本体部1,固定部挿入孔2及び被係止貫通孔3とからなる。その反射本体部1は、その断面形状が略U字形状に形成されたものであるがさらに具体的には、断面略湾曲状とした2つの反射面板部1a,1aが左右対称に形成されたものである。それぞれの反射面板部1a,1aは、その断面形状が方物線,インボリュート曲線又はその形状を適宜に組み合わせた形状に形成され、後述する管部材10に対して太陽光が集中的に反射することができる形状に形成されている。
【0009】
具体的には、図3(A)に示すように、反射部材Aの幅方向(すなわち、該反射部材Aの長手方向に直交する断面)において、両反射面板部1a,1aが幅方向両側端より、その幅方向中心箇所に向かってインボリュート曲線又は放物線等の曲線に沿って曲面が形成されたものであり、そのインボリュート曲線とした面が反射部材Aの長手方向に沿って同一形状に連続形成されている。
【0010】
その2つの反射面板部1a,1aは、幅方向に沿って断面略W字形状となるように形成され、両反射面板部1a,1aの交わる部位、すなわち反射部材Aの幅方向中心箇所が上方に向かって突出形成される中央頂部1bが形成されている。該中央頂部1bは、小山形状部位であり前記反射本体部1が断面略W字形状に見えることもある。
【0011】
そして、通常では図1(B),(C),図2(B)及び図8(C)等に示すように、ひとつの反射部材Aには、2つの反射本体部1,1が備えられており、この反射部材Aが幅方向に沿って複数並設されるものである。その隣接する反射本体部1,1の一方の反射本体部1の外端頂部には、外方下向きに傾斜する小折返し片状の折返し連結部1cが形成されている。該折返し連結部1cが隣接する反射部材Aの反射本体部1の幅方向頂部に重合されるようにして反射部材A,A同士が連結されるものである。また、特に図示しないがひとつの反射部材Aには、前記反射本体部1が3以上形成されることもある。
【0012】
その反射面板部1a,1aがインボリュート曲線等の線形状に形成される場合には、前記中央頂部1b上に架設された管部材10の断面形状を直径Dなる円形とすると、前記反射面板部1a,1aは、前記管部材10の円形を基準(基礎円)にしたインボリュート曲線となる。即ち、管部材10の円形断面の周囲より仮想紐をほどいたときの紐端の軌跡である。そして、管部材10の円形に対して反時計回りに紐をほどいた軌跡に従って形成された反射面板部1a,1aは、前記管部材10の右側に位置する。そして、前記管部材10の円形に対して時計回りに紐をほどいた軌跡に従って形成された反射面板部1aは、前記管部材10の左側に位置する。両反射面板部1a,1aは、鏡面仕上げ材が施されている。
【0013】
その反射本体部1には、長手方向に沿って適宜の間隔をおいて固定部挿入孔2が形成されている〔図2(B)参照〕。該固定部挿入孔2は、線状,筋状或いはスリット形状に形成されたものであって、反射部材Aの長手方向に対して略直交する方向に略線状,筋状或いはスリット形状にして形成されている。その固定部挿入孔2は、具体的には後述する受け台Bの固定部6が遊挿する程度の大きさの貫通孔であり、その孔形状は、前記反射部材Aの長手方向に直交する方向に沿って略長方形状又は筋形状に形成されたものである。そして、前記固定部挿入孔2は、前記反射部材Aの幅方向略中央箇所で、且つ前記中央頂部1b箇所を通過するようにして形成される。
【0014】
また、前記反射部材Aには、被係止貫通孔3が形成されている。該被係止貫通孔3には、後述する受け台Bの係止部7が遊挿され、反射部材Aが受け台Bに前記係止部7とともに固定される役目をなす部位である。その被係止貫通孔3は、前記固定部挿入孔2に近接して形成されており、具体的には両反射面板部1a,1aにそれぞれ形成される。また、その被係止貫通孔3は、前記固定部挿入孔2に比較して短い線(筋,スリット)状の貫通孔として形成されている。
【0015】
次に、受け台Bは、前記反射部材Aを所定位置に設置する役目をなすものであり、図2(C)に示すように、支持部5,固定部6及び係止部7とから構成されている。そして、1つの受け台Bに対してその支持部5は、2つ形成されている〔図2(C)参照〕。両支持部5,5は、相互に平行に対向しており、その一方の支持部5には固定部6が形成され、他方の支持部5には係止部7が形成されている。
【0016】
それぞれの支持部5は、略垂直板状をなしており、その頂部端縁が支持頂部5aとなっており、前記反射部材Aは該支持頂部5aによって当接支持される。該支持頂部5aは、図1(B),(C)及び図3(B),図4等に示すように、前記反射部材Aの下面側に略当接状態に支持するものである。その支持頂部5aは、図3(A)に示すように、前記両反射面板部1a,1aの形状に沿って略均一に当接するように湾曲状の凹み部として形成され、前記反射部材Aの裏面側と当接し易い形状に形成されたものである。
【0017】
次に、固定部6は、管部材10を前記反射部材A上に固定する部位であって、複数のタイプが存在する。その第1タイプでは、図2(C),図3(A)に示すように、2つの挟持片6a,6aが形成されている。両挟持片6a,6a間の底部箇所は、管部材10の外周を安定した状態で支持することができるように、略半円形状の弧状支持底部6bとして形成されている。前記両挟持片6a,6aは、初期状態では、図1(C),図2(C)及び図3等に示すように、略垂直状に立ち上がり形成されている。そして、管部材10を両挟持片6a,6a間に配置した状態で、両挟持片6a,6aは、管部材10の外周に沿って折り曲げることができるようになっている〔図4(B)参照〕。この両挟持片6a,6aの折り曲げにて固定部6に管部材10を固定することができる。
【0018】
この両挟持片6a,6aの折り曲げは、金属の塑性変形によるもので、ハンマー等の工具を介して比較的容易に折り曲げることができる程度の外形に形成されている。また、両挟持片6a,6aを管部材10の外周に折り曲げたときには、図4(B)に示すように、その管部材10は前記弧状支持底部6bと両挟持片6a,6aにより管部材10の外周が包囲されるようになっている。すなわち、固定部6にて固定される管部材10の上方箇所では両挟持片6a,6aの上端が相互に重なり合うようになっている〔図1(B)参照〕。両挟持片6a,6aの先端箇所には相互に内方に向かってわずかに膨出する膨出部6a1 ,6a1 が形成され、挟持片6a,6aを折り曲げて後述する管部材10を固定するときに良好に馴染めるようにすることができる。
【0019】
次に、固定部6の第2タイプでは、図5に示すように、両挟持片6a,6aの上端に嵌合突起部6a2 ,6a2 が対向して形成されたものである。このタイプでは、管部材10が両嵌合突起部6a2 ,6a2 により嵌合固定されるもので、両挟持片6a,6aの上方より、管部材10を押し込むと、該管部材10が前記両嵌合突起部6a2 ,6a2 を介して両挟持片6a,6aが弾性的に押し拡げられ、管部材10が弧状支持底部6bに当接すると、両挟持片6a,6aは復元して、前記嵌合突起部6a2 ,6a2 が管部材10を固定することができる。その支持部5の下端には台座部8が形成され、該台座部8はボルト,ビス等の固着具を介して所定の設置場所に固定される。さらに固定部6の第3タイプでは、図6に示すように、前記管部材10を横方向より嵌合挿入して装着するものであり、前記嵌合突起部6a2 ,6a2 が上下方向に形成されている。
【0020】
次に、前記係止部7は、受け台Bに反射部材Aを固定する役目をなすものであり、図2(C)に示すように、前記支持部5の支持頂部5aに略突起片状に形成されたものである。この係止部7には、複数のタイプが存在し、その第1タイプとして、図7(A)に示すように、前記被係止貫通孔3に係止部7が挿入され、その挿入されたのち、図7(B)に示すように、前記係止部7が初期状態から略直角となるように捩じり、該係止部7が被係止貫通孔3より抜け出さないようにされたものである。その係止部7の捩じり加工は、ペンチ等の工具が使用される。前記係止部7は、前記両支持頂部5a,5aにそれぞれ形成されている。
【0021】
その係止部7の第2タイプとしては、図7(C)に示すように、前記被係止貫通孔3に挿入したのち、前記係止部7を反射部材Aの反射本体部1表面に向けて折り曲げるものである。その係止部7の第3タイプとしては、図7(D)に示すように、鉤形状に形成されたものが存在する。これは鉤形状又はフック形状としたものである。前記反射部材Aに形成される被係止貫通孔3は少し小さめに形成されたもので、係止部7の頭部箇所より狭く形成されている。
【0022】
そして、反射部材Aを受け台B方向に強く押しつけるようにすると、被係止貫通孔3に係止部7が圧入状態で押し込まれ、一旦,被係止貫通孔3に挿入すると、略嵌め殺し状態で係止部7が被係止貫通孔3から抜け出さない構造となる。この係止部7の第3タイプは、前述した第1タイプの係止部7のように被係止貫通孔3に挿入してから折り曲げたり或いは捩じれ変形させたりする必要がない。この受け台Bの支持部5は、幅方向に複数が連続している。この受け台Bの幅方向における支持部5の数は、後述するフレームCに装着される管部材10の装着数によって適宜に設定されるものである。
【0023】
次に、前記管部材10は、外径Dなる直径を有しており、また反射部材Aがインボリュート曲線の反射面板部1a,1aからなる場合には、その管部材10は両反射面板部1a,1aのインボリュート曲線の基準円となる。前記管部材10は、前記中央頂部1bの上方に位置して配置固定され、反射部材Aに差し込む太陽の反射光が管部材10の中心に向かって集中する。また、管部材10の外面は黒色となっていることが好ましい。
【0024】
この反射部材Aと受け台B及び管部材10は、図1(A),図8(A)に示すように、フレームCに収納されており、家屋の屋根,屋上等に装着されるものである。そのフレームCは、図8(B),(C)に示すように、フレーム本体部20と集光窓部21とから構成されたものであり、該集光窓部21は、集光板21aと窓枠部21bとから構成されたものである。前記フレーム本体部20は、底面部20a及び側部20bが断熱性を有する部材にて構成されることが好ましい。側部20bの断熱性を有する材質としては、合成樹脂などである。上記フレームCは横方向又は長手方向が約2m程度で、縦方向が約1m程度とした長方形であるが、そのサイズには特に限定されるものではない。
【0025】
そして、その集光板21aは、図8(B),(C)に示すように、2層式であり、その内部にクリプトンガスが充填されたもの等のように断熱性に優れたものが好適であり、且つ強化ガラスが使用されることが好ましい。またアクリル等を使用してもよい。その集光窓部21が窓枠部21b及びゴムパッキン及びビス等の固着具を介してフレーム本体部20に取り付けられる。そのフレーム本体部20の底面部20aには断熱板材22が敷設されている。該断熱板材22は合成樹脂等から形成されたものであり、この断熱板材22上に前記受け台Bが配置固着される。
【0026】
前記断熱板材22は、図8(C)に示すように、2枚重ねとしてフレーム本体部20の底面部20a上に敷設されるものであるが、その上方側の断熱板材22にはビス等の取付用固着具23が植設されており、この取付用固着具23によって前記受け台Bが固定されるものである。その取付用固着具23のビスは先端部が先鋭な円錐状のものが使用される。
【0027】
まず、複数の支持部5と固定部6とを備えた通し状の受け台Bが前記フレーム本体部20の底面部20aに敷設された断熱板材22上に、フレーム本体部20の幅方向に沿って配置され、取付用固着具23を介して固着される。また、その受け台Bは、前記フレーム本体部20の長手方向に沿って適宜の間隔をおいて配置される。実際には、上方に位置する断熱板材22が下方に位置する断熱板材22上に配置される前に、その断熱板材22に取付用固着具23を介して受け台Bが固着されるものである。
【0028】
そのフレーム本体部20に配置された複数の受け台B,B,‥の固定部6によって管部材10が固定されてゆく。前記管部材10は、その軸方向とフレームCの横方向(長手方向)とが一致するようにして配置され、そのフレーム本体部20の長手方向の端部箇所には屈曲管部材10aを介して平行に配列された管部材10,10同士が連結される。そして、フレーム本体部20の幅方向の両端に配置されている管部材10,10にはフレームCに装着されている給水管24と送出管25にそれぞれ連結されている。前記給水管24及び送出管25によって管部材10,10,‥内の熱せられた水が風呂,キッチン,洗面所等の温水が必要な箇所に供給される。
【0029】
次に、本発明における装置の組立について、説明すると、前記フレームCの底面部20aに断熱板材22が敷設され、該断熱板材22上に受け台Bが固着される。該受け台BはフレームCの長手方向に適宜の間隔をおいて配置されるものであるが、管部材10を安定した状態で支持することができる程度の間隔する。次に、反射部材Aが受け台B上に配置されるが、図3に示すように、反射部材Aの固定部挿入孔2に受け台Bの固定部6が挿通し、該固定部6が反射部材Aの反射本体部1上に突出するように設定される。次に、図4に示すように、管部材10が前記固定部6の挟持片6a,6a間に配置され、前記管部材10が両挟持片6a,6aにて挟持固定される。両挟持片6a,6aは管部材10を挟持した状態で折り曲げて管部材10を固定するものである。
【0030】
【発明の効果】
請求項1の発明は、断面左右対称且つ略W字形状に形成され,それぞれがインボリュート曲面に形成された反射本体部の長手方向に沿って適宜の間隔をおいて固定部挿入孔2及び被係止貫通孔3が形成された反射部材Aと、該反射部材Aの裏面側をその形状に沿って当接状態に支持する支持部5と前記反射部材Aの固定部挿入孔2に挿通して前記反射本体部1の表面上に突出する固定部6とを有する受け台Bと、前記反射部材A上に架設される管部材10とからなり、該管部材10は前記固定部6に設けた挟持片6aにより反射本体部1上に固定されると共に、前記反射部材Aの被係止貫通孔3に前記係止部7が挿入されて、該係止部7は折り曲げ,捩じり変形又は嵌合にて前記反射部材Aは受け台Bに固定されてなる太陽光反射装置としたことによりその組立が簡単にでき、施工効率を向上させることができる等の効果を奏する。
【0031】
上記効果を詳述すると、反射部材Aは、断面左右対称且つ略W字形状に形成され,それぞれがインボリュート曲面に形成された反射本体部1の長手方向に沿って適宜の間隔をおいて固定部挿入孔2が形成されている。また受け台Bは、前記反射部材Aの裏面側をその形状に沿って当接状態に支持する支持部5と前記反射部材Aの固定部挿入孔2に挿通して前記反射本体部1の表面上に突出する固定部6とを有している。前記固定部6は、前記反射部材A上に挿通して表面上に突出した状態で管部材10を固定するものである。
【0032】
このように、受け台Bは、支持部5と固定部6とを有しているので、管部材10を反射部材A上に装着するのに、ボルト,ナット等の固着具等は一切不要であり、現場において反射部材Aに加工を一切行う必要がなく、作業効率を向上させることができるものである。しかも、受け台Bは、支持部5と固定部6とを有しているので、反射部材Aが受け台Bによって支持されるようにするのと略同時に管部材10を反射部材Aの表面上に固定することができ、太陽光反射装置の組み立てを迅速且つ簡単にでき、ひいては施工効率を向上させることができるものである。
【0033】
請求項2の発明においては、請求項1において、前記受け台Bの支持部5の頂部から固定部6が一体的に形成されてなる太陽光反射装置としたことにより、支持部5と固定部6とが一体的に形成された構造となり、前記反射部材Aの固定部挿入孔2に固定部6を遊挿するのみで、支持部5の頂部箇所が反射部材Aの裏面側に当接して反射部材Aを支持することができ、さらに組立作業を効率的に行うことができる。
【0034】
請求項3の発明は、請求項1又は2において、前記受け台Bは2つの支持部5,5が形成され、その一方の支持部5に前記固定部6が形成され、他方の支持部5に係止部7が形成されてなる太陽光反射装置としたことにより、固定部6と係止部7とがそれぞれ異なる支持部5,5に形成され、前記固定部6と係止部7とが相互に異なる位置となる。それゆえに、前記係止部7の位置が前記固定部6の位置から離れた位置となり、その係止部7の捩じり又は曲げ作業が行いやすくなり、ひいては受け台Bと反射部材Aとの組立作業を行いやすくすることができるものである。
【0035】
請求項4の発明は、請求項1,2又は3において、前記挟持片6aは2つからなり、前記管部材10は両挟持片6a,6aにて挟持固定されてなる太陽光反射装置としたことにより、管部材10を固定部6に固定することが極めて簡単にできる。
【0036】
請求項5の発明は、請求項1,2,3又は4において、前記挟持片6a,6aは、折曲自在としてなる太陽光反射装置としたことにより、管部材10を挟持片6a,6a間に配置し、その管部材10の外周に巻き付けるようにして前記挟持片6a,6aを折り曲げることにより、管部材10は固定部6に極めて強固な状態で固定されるものである。
【0037】
請求項6の発明は、請求項4又は5において、前記両挟持片6a,6aにはそれぞれに嵌合突起部6a2 ,6a2 が対向して形成されてなる太陽光反射装置としたことにより、管部材10は両挟持片6a,6a間に配置するのみで、前記管部材10は前記嵌合突起部6a2 ,6a2 に嵌合固定され、極めて簡単に固定することができる。
