上記従来の太陽電池モジュールの固定構造は、枠体の外側に係合溝部を有するものが対象であり、係合溝部を有しない枠体には、カバーを係合させることができないので、適用することができない。カバー下で見えにくく、かつ狭い隣接モジュール間の空間に手を差し入れて、ボルト、ナット及びカバーの結合作業を行わなければならないので、時間のかかる難作業となる。また、ナットが上方へ突出するので外観を損ねる難点がある。
したがって、この出願に係る発明は、上記のようなボルト、ナット及びカバーの結合作業を不要とし、表側からの施工のみで容易に太陽電池モジュールを固定できる、汎用性の高い新規の固定装置を提供することを目的としている。 The conventional solar cell module fixing structure described above is applicable to a structure having an engaging groove on the outside of the frame, and the cover cannot be engaged with a frame that does not have an engaging groove. I can't. Since it is difficult to see under the cover and a hand is inserted into the space between the narrow adjacent modules and the bolts, nuts, and cover must be joined, this is a time-consuming and difficult task. Further, since the nut protrudes upward, there is a problem that the appearance is impaired.
Therefore, the invention according to this application provides a new versatile fixing device that eliminates the need for the above-described bolt, nut, and cover connection operation and can easily fix the solar cell module only by construction from the front side. The purpose is to do.

図面を参照してこの発明の実施の形態を説明する。
本発明に係る太陽電池モジュールの固定装置が適用される太陽電池モジュール４０は、図２、図6に示すように、複数の太陽電池セルを搭載した矩形板状の本体４１と、それの四囲を囲む枠体４２とを具備する。枠体４２は、上部の内側に、本体４１の外周縁部を挟持する上下一対の挟持片４２ａ、４２ｂを有すると共に、下部に内向きフランジ４２ｃを具備する。ここで「上」とは、太陽電池モジュール本体４１の受光面側、「下」とはその反対側、すなわち屋根などの支持部材側を意味する。
太陽電池モジュールの固定装置は、太陽電池モジュール４０を支持部材Ｓ上に複数並べて固定するためのものであり、支持レール１と、この支持レール１に装着される固定金具組立体２とを具備する。図6に示すように、太陽電池モジュール４０は、それぞれ４つの固定金具組立体２により、２本の支持レール１上に固定される。
図１，２に示すように、支持レール１は、Ｃ形鋼材からなり、リップ１ａを上に向けて、支持部材Ｓ(図４〜５)上に複数が平行に、相互間隔を置いて固定される。図６に支持レール１を２本だけ示した。太陽電池モジュール４０の内向きフランジ４２ｃが、支持レール１のリップ１ａ上に載置される。
固定金具組立体２は、ベース部材３と、押さえ部材４と、板ばね５とを具備し、太陽電池モジュールの対向する枠体（横枠体）４２に対応する位置において、支持レール１の溝４内に装着される。
ベース部材３は、支持レールの溝１ｂ内においてウェブ１ｃ上に固定される本体
６と、ウェブ１ｃに対して垂直に起立するように固定される固定ボルト７と、これに螺合するナット８とを具備する。
ベース部材本体６は、底板部６ａと側板部６ｂとを具備する。底板部６ａは、支持レールのウェブ１ｃとの間で固定ボルト７の頭部を回転不可能に保持するボルト保持部６ｃと、固定ボルト７の軸を上方へ突出させるボルト孔６ｄを有する。側板部６ｂは、底板部６ａの両縁から直角に屈曲して、支持レールのフランジ１ｄの内側面に沿い、ねじ孔６ｅを有する。ベース部材３は、フランジ１ｄのボルト孔１ｅを貫通してねじ孔６ｅに螺合されるボルト９で支持レール１の所定位置に固定される。
押さえ部材４は、スライド板部１０と、これと一体の一対の係合部１１，１２とを具備し、支持レールの溝１ｂ内にあって、ベース部材３上に板ばね５を介して配置される。
スライド板部１０は、ボルト７を貫通させる長孔１０ａを有し、ベース部材３の底板部６ｃ上に重なる平板状であり、長孔１０ａの範囲で、待機位置（図３Ａ，図４Ａ）とセット位置（図３Ｂ，図４Ｂ）との間を支持レール１の延長方向に移動自在である。
係合部１１，１２は、スライド板部５の可動方向の両端部に位置して、支持レール１の溝外に延出し、太陽電池モジュール４０の内向きフランジ４２ｃに係合可能である。すなわち、係合部１１，１２は、それぞれスライド板部１０から直角に起立して支持レール１の溝外へ延出する起立板部１１ａ，１２ａと、この起立板部の上端からスライド板部１０と平行に、相対向する方向に延出する押圧片１１ｂ，１２ｂとを具備する。
しかして、押さえ部材４は、セット位置（図３Ｂ，図４Ｂ）において、固定ボルト７に螺合されるナット８の締め付けにより、押圧片１１ｂ，１２ｂと支持レールのリップ１ａとの間で、太陽電池モジュールの内向きフランジ４２ｃを挟んで固定する。
板ばね５は、ベース部材３と押さえ部材４との間に介設され、図３Ａ，図４Ａに示すように、押さえ部材４を弾性的に押し上げて、リップ１ｃと押圧片１１ｂ，１２ｂとの間を開いた解放位置に保持する。
すなわち、図１に示すように、板ばね５は、平板状の基板部５ａと、それの両端側に立ち上がる脚部５ｃとを有する。基板部５ａは、ベース部材３のボルト孔６ｄに対応して、ボルト７を貫通させるボルト孔５ｂを有する。脚部５ｃは、押さえ部材４を摺動自在に押し上げる。したがって、押さえ部材４は、ナット８が緩められた解放状態（図４Ａ，図５）において、脚部５ｃ上を待機位置（図３Ａ，図４Ａ）からセット位置（図３Ｂ，図４Ｂ）へ摺動し、またセット位置（図３Ｂ，図４Ｂ）において、ナット８の締め付けにより、板ばね５を圧縮して押圧片１１ｂとリップ１ｃとの間で太陽電池モジュールの内向きフランジ４２ｃを挟持することができる。
太陽電池モジュール４０は、この固定装置を用いて、図６に示すように支持レール１上に固定される。２つの太陽電池モジュール４０Ａ、４０Ｂを屋根等の支持部材上に取り付けるまでの工程を図７ないし図１０について説明する。なお、これらの図において、太陽電池モジュール４０は、その固定構造が明らかになるように、枠体４２のみで示している。
まず、最初の太陽電池モジュール４０Ａの取り付けについて、図７に示すように、４つの固定金具組立体２を一対の支持レール１上の所定位置に固定する。いずれの固定金具組立体２についても、ナット８が弛められ、押さえ部材４が解放位置（図４Ｂ）にある。図７において上方の固定金具組立体２Ａの押さえ部材４はセット位置に配置され、下方の固定金具組立体２Ｂの押さえ部材４は待機位置に配置される。
この状態で、図８に示すように、上方の固定金具組立体２Ａの係合部１２ｂ上に上縁部が被さるように、第１の太陽電池モジュール４０Ａをレール１上へ載置して、これを下方へスライドさせると、上方の枠体の内向きフランジ４２ｃが押圧片１２ｂとリップ１ａとの間に進入して係合部１２にくわえ込まれる。この状態で、ナット８を締め付けて、押圧片１２ｂとリップ１ａとの間に上枠の内向きフランジ４２ｃを挟持する。これで第１の太陽電池モジュール４０Ａの上枠が固定される（図３Ｂ、図４Ｂの状態）。
同時に、第１の太陽電池モジュール４０Ａの下縁部が、下方の固定金具組立体２Ｂの係合部１１上に被さるように、支持レール１上に置かれる。この状態で、固定金具組立体２Ｂの押さえ部材４の一部（図８における下方部分）は、太陽電池モジュール４０Ａの下方の枠体４２の外側（下方）に延出しており、押さえ部材４の係合部１１ｂは内向きフランジ４２ｃに係合していない。ボルト７、ナット８も太陽電池モジュール４０Ａの下方の枠体４２の外側にある（図３Ａ、図４Ａの状態）。
次いで、枠体４２の外側に延出している下方の固定金具組立体２Ｂの押さえ部材４を下方へ引いてスライドさせると、図９の状態となり、下方の枠体の内向きフランジ４２ｃに係合部１２が係合する。この状態で、ナット８を締め付けて、フランジ４２ｃを押圧片１２ｂとリップ１ａとの間に挟持する。これで第１の太陽電池モジュール４０Ａの固定が完了する。
次いで、図１０に示すように、第２の太陽電池モジュール４０Ｂの上縁部を下方の固定金具組立体２Ｂの係合部１２上に被さるように、支持レール１上に置き、順次上枠から下枠へと、第１の太陽電池モジュール４０Ａと同様に支持レール上に固定する。この工程の繰り返しで、次々に太陽電池モジュール４０を固定していく。以上すべての太陽電池モジュール４０の固定作業を上方から効率よく行うことができる。図６に示すように、固定ボルト７は、常に、支持レール１上に隣接配置される２つの太陽電池モジュール４０の相互間隔内に配置されるから、ナット８の締め付け操作は、この間隔の上方から難なく行うことができる。
なお、支持レール１は、個々の固定金具組立体２に対応する長さの短尺のものを、１枚の太陽電池モジュール４０について４つずつ、支持部材上に固定する形式でもよい。 Embodiments of the present invention will be described with reference to the drawings.

The board portion 5 a has bolt holes 5 b that allow the bolts 7 to pass therethrough corresponding to the bolt holes 6 d of the base member 3. The leg part 5c pushes up the pressing member 4 slidably. Therefore, the holding member 4 slides on the leg 5c from the standby position (FIGS. 3A and 4A) to the set position (FIGS. 3B and 4B) in the released state (FIGS. 4A and 5) in which the nut 8 is loosened. In the set position (FIG. 3B, FIG. 4B), the leaf spring 5 is compressed by tightening the nut 8 to sandwich the inward flange 42c of the solar cell module between the pressing piece 11b and the lip 1c. Can do.
Using this fixing device, the solar cell module 40 is fixed on the support rail 1 as shown in FIG. A process until two solar cell modules 40A and 40B are mounted on a support member such as a roof will be described with reference to FIGS. In these drawings, the solar cell module 40 is shown only by the frame body 42 so that the fixing structure becomes clear.
First, as shown in FIG. 7, with respect to the attachment of the first solar cell module 40 </ b> A, the four fixing bracket assemblies 2 are fixed at predetermined positions on the pair of support rails 1. In any of the fixing bracket assemblies 2, the nut 8 is loosened and the pressing member 4 is in the release position (FIG. 4B). In FIG. 7, the pressing member 4 of the upper fixing bracket assembly 2A is disposed at the set position, and the pressing member 4 of the lower fixing bracket assembly 2B is disposed at the standby position.
In this state, as shown in FIG. 8, the first solar cell module 40A is placed on the rail 1 so that the upper edge portion covers the engaging portion 12b of the upper fixing bracket assembly 2A. When this is slid downward, the inward flange 42c of the upper frame enters between the pressing piece 12b and the lip 1a and is held in the engaging portion 12. In this state, the nut 8 is tightened to hold the inward flange 42c of the upper frame between the pressing piece 12b and the lip 1a. Thus, the upper frame of the first solar cell module 40A is fixed (the state shown in FIGS. 3B and 4B).
At the same time, the lower edge portion of the first solar cell module 40A is placed on the support rail 1 so as to cover the engaging portion 11 of the lower fixture assembly 2B. In this state, a part of the pressing member 4 of the fixing bracket assembly 2B (the lower part in FIG. 8) extends to the outside (downward) of the frame 42 below the solar cell module 40A. The engaging portion 11b is not engaged with the inward flange 42c. The bolt 7 and the nut 8 are also outside the frame body 42 below the solar cell module 40A (the state shown in FIGS. 3A and 4A).
Next, when the holding member 4 of the lower fixing bracket assembly 2B extending outside the frame body 42 is pulled downward and slid, the state shown in FIG. 9 is obtained, and it engages with the inward flange 42c of the lower frame body. Part 12 engages. In this state, the nut 8 is tightened to hold the flange 42c between the pressing piece 12b and the lip 1a. This completes the fixing of the first solar cell module 40A.
Next, as shown in FIG. 10, the upper edge of the second solar cell module 40B is placed on the support rail 1 so as to cover the engaging portion 12 of the lower fixture assembly 2B, and sequentially from the upper frame. It fixes to a lower frame on a support rail similarly to 40 A of 1st solar cell modules. The solar cell modules 40 are fixed one after another by repeating this process. All the solar cell modules 40 can be fixed efficiently from above. As shown in FIG. 6, the fixing bolt 7 is always arranged within the mutual interval between the two solar cell modules 40 arranged adjacent to each other on the support rail 1, so that the tightening operation of the nut 8 is performed above this interval. Can be done without difficulty.
Note that the support rails 1 may be of a type in which a short length corresponding to each fixing bracket assembly 2 is fixed on the support member four by one for each solar cell module 40.
