Further, the second connection part 42 is connected to the second frame part 32 of the second solar panel 22. The configuration of the second connecting portion 42 is the same as that of the first connecting portion 41, and the description thereof is omitted.

図５は、第１連結部４１および第２連結部４２の斜視図である。図６は、第１連結部４１および第２連結部４２が連結される様子を示す図である。図７は、第１連結部４１および第２連結部４２の上面図である。図６に示すように、本実施形態の第１連結部４１および第２連結部４２は、それぞれ、第１貫通孔４１１および第２貫通孔４２２を有する。第１貫通孔４１１は、例えば、第１連結部４１のうち、第１枠部３１の開口部３５に挿入される端部とは異なる端部側に設けられる。また、第２貫通孔４２２は、例えば、第２連結部４２のうち、第２枠部３２の開口部３５に挿入される端部とは異なる端部側に設けられる。   FIG. 5 is a perspective view of the first connecting portion 41 and the second connecting portion 42. FIG. 6 is a diagram illustrating a state in which the first connecting portion 41 and the second connecting portion 42 are connected. FIG. 7 is a top view of the first connecting portion 41 and the second connecting portion 42. As shown in FIG. 6, the first connecting portion 41 and the second connecting portion 42 of the present embodiment have a first through hole 411 and a second through hole 422, respectively. The first through-hole 411 is provided, for example, on an end of the first connecting portion 41 that is different from an end inserted into the opening 35 of the first frame 31. The second through-hole 422 is provided, for example, on an end of the second connecting portion 42 that is different from an end inserted into the opening 35 of the second frame 32.

回動部５０は、第１連結部４１および第２連結部４２を回動可能に繋ぐ。図６および図７に示すように、本実施形態の回動部５０は、第１貫通孔４１１および第２貫通孔４２２を連通する軸部である。具体的には、第１連結部４１および第２連結部４２は、第１貫通孔４１１および第２貫通孔４２２が対向するように配置される。そして、回動部５０であるボルトの軸部は、第１貫通孔４１１および第２貫通孔４２２を連通する。これにより、第１連結部４１および第２連結部４２は、回動部５０であるボルトの軸部を中心に、回動可能に繋がれる。   The rotation unit 50 rotatably connects the first connection unit 41 and the second connection unit 42. As shown in FIGS. 6 and 7, the rotating part 50 of the present embodiment is a shaft part that connects the first through hole 411 and the second through hole 422. Specifically, the first connecting portion 41 and the second connecting portion 42 are arranged such that the first through hole 411 and the second through hole 422 face each other. Then, the shaft portion of the bolt, which is the rotating portion 50, communicates the first through hole 411 and the second through hole 422. Thus, the first connecting portion 41 and the second connecting portion 42 are rotatably connected around the shaft portion of the bolt, which is the rotating portion 50.

なお、本実施形態では、連結装置１０は、２つの第１連結部４１および２つの第２連結部４２を有する。そして、２つの第１連結部４１は、それぞれ、回動部５０によって、第２連結部４２と回動可能に繋がれる。しかしながら、第１枠部３１に連結される第１連結部４１および第２枠部３２に連結される第２連結部４２の数は、それぞれ１つであってもよく、３つ以上であってもよい。   In the present embodiment, the connection device 10 has two first connection portions 41 and two second connection portions 42. The two first connecting portions 41 are rotatably connected to the second connecting portion 42 by the turning portions 50, respectively. However, the number of the first connecting portions 41 connected to the first frame portion 31 and the number of the second connecting portions 42 connected to the second frame portion 32 may be one, three or more. Is also good.

保持部６０は、第１連結部４１および第２連結部４２を任意の角度にして回動部を保持する。図５〜図７に示すように、本実施形態の保持部６０は、ボルトの頭部およびナットにより構成される。そして、回動部５０であるボルトの軸部は、第１貫通孔４１１および第２貫通孔４２２に連通され、ナットに締め付けられる。これにより、保持部６０は、第１連結部４１および第２連結部４２を挟持する。すなわち、保持部６０であるボルトの頭部およびナットは、回動部５０であるボルトの軸部の両端側から、第１連結部４１および第２連結部４２を挟持する。これにより、回動された第１連結部４１および第２連結部４２は、保持される。   The holding section 60 holds the rotating section by setting the first connecting section 41 and the second connecting section 42 to arbitrary angles. As shown in FIGS. 5 to 7, the holding unit 60 of the present embodiment is configured by a head of a bolt and a nut. Then, the shaft portion of the bolt, which is the rotating portion 50, is communicated with the first through hole 411 and the second through hole 422, and is fastened to the nut. As a result, the holding section 60 sandwiches the first connecting section 41 and the second connecting section 42. That is, the head and the nut of the bolt that is the holding part 60 sandwich the first connecting part 41 and the second connecting part 42 from both ends of the shaft part of the bolt that is the rotating part 50. Thereby, the rotated first connection portion 41 and second connection portion 42 are held.

また、図６に示すように、本実施形態の第１連結部４１は、第２連結部４２と接触する第１接触面４３１を有する。また、第１貫通孔４１１は、第１接触面４３１を含む第１連結部４１の端部に形成される。そして、第１連結部４１の端部は、他の部分よりも厚みが薄く、かつ、円形状である。また、本実施形態の第２連結部４２は前記第１連結部４１と接触する第２接触面４３２を有する。そして、第２接触面４３２を含む第２連結部４２の端部は、他の部分よりも厚みが薄く、かつ、円形状である。これにより、第１連結部４１および第２連結部４２を、回動部５０により容易に回動させることができる。また、第１連結部４１と第２連結部４２とを、略同一直線上に延びるように接続できる。その結果、複数の太陽光パネルを容易に配列できる。なお、第１連結部４１および第２連結部４２の端部は、円形状とは異なる形状であってもよい。また、第１連結部４１および第２連結部４２の端部の厚みは、その他の部分の厚みと同一であってもよい。   As shown in FIG. 6, the first connecting portion 41 of the present embodiment has a first contact surface 431 that contacts the second connecting portion 42. In addition, the first through hole 411 is formed at an end of the first connecting portion 41 including the first contact surface 431. The end of the first connecting portion 41 is thinner than other portions and has a circular shape. In addition, the second connecting portion 42 of the present embodiment has a second contact surface 432 that contacts the first connecting portion 41. The end of the second connecting portion 42 including the second contact surface 432 is thinner than other portions and has a circular shape. Thereby, the first connecting portion 41 and the second connecting portion 42 can be easily rotated by the rotating portion 50. Further, the first connecting portion 41 and the second connecting portion 42 can be connected so as to extend substantially on the same straight line. As a result, a plurality of solar panels can be easily arranged. Note that the ends of the first connecting portion 41 and the second connecting portion 42 may have a shape different from a circular shape. Further, the thickness of the ends of the first connecting portion 41 and the second connecting portion 42 may be the same as the thickness of the other portions.

なお、本実施形態の第１連結部４１は、第１枠部と回動部５０との距離を調整する第１調整部４４１を有する。本実施形態の第１調整部４４１は、例えば、第１連結部４１の延びる長手方向（第１連結部４１が開口部３５に挿入される方向）に並べて設けられた複数の孔部である。また、第１調整部４４１である複数の孔部は、ネジ穴となっている。第１連結部４１が開口部３５内に挿入されると、第１枠部３１の外側から孔部８を介して、第１調整部４４１である孔部に対してボルトが挿入される。これにより、第１連結部４１は、第１枠部３１に固定される。   The first connecting portion 41 of the present embodiment has a first adjusting portion 441 that adjusts the distance between the first frame portion and the rotating portion 50. The first adjusting portion 441 of the present embodiment is, for example, a plurality of holes provided side by side in the longitudinal direction of the first connecting portion 41 (the direction in which the first connecting portion 41 is inserted into the opening 35). The plurality of holes serving as the first adjustment unit 441 are screw holes. When the first connecting portion 41 is inserted into the opening 35, a bolt is inserted into the hole as the first adjusting portion 441 from the outside of the first frame portion 31 via the hole 8. Thereby, the first connecting portion 41 is fixed to the first frame portion 31.

ここで、第１枠部３１と保持部６０との距離を長くする場合、第１調整部４４１である複数の孔部のうち、第１連結部４１のうち開口部３５に挿入される端部側の孔部にボルトを挿入する。一方で、第１枠部３１と保持部６０との距離を短くする場合、第１調整部４４１である複数の孔部のうち、保持部６０に近い孔部にボルトを挿入する。このように、第１調整部４４１を設けることで、第１枠部３１と回動部５０との距離を任意に調整することができる。その結果、より複雑な設置面に対しても、複数の太陽光パネルを連結しつつ設置することができる。   Here, when increasing the distance between the first frame portion 31 and the holding portion 60, the end portion of the first connecting portion 41 inserted into the opening 35 of the plurality of holes that are the first adjusting portion 441. Insert the bolt into the side hole. On the other hand, when shortening the distance between the first frame portion 31 and the holding portion 60, a bolt is inserted into a hole near the holding portion 60 among the plurality of holes serving as the first adjustment portion 441. Thus, by providing the first adjusting portion 441, the distance between the first frame portion 31 and the rotating portion 50 can be arbitrarily adjusted. As a result, it is possible to install a plurality of solar panels while connecting them to a more complicated installation surface.

また、本実施形態の第２連結部４２は、第２枠部と回動部５０との距離を調整する第２調整部４４２を有する。第２調整部４４２の構成については、第１調整部４４１と同様であるため、その説明を省略する。   The second connecting portion 42 of the present embodiment has a second adjusting portion 442 for adjusting the distance between the second frame portion and the rotating portion 50. The configuration of the second adjustment unit 442 is the same as that of the first adjustment unit 441, and a description thereof will be omitted.

また、本実施形態の第１枠部３１は、第１連結部４１を第１枠部３１に沿った方向に案内する第１ガイド部３１１を有する。図３に示すように、本実施形態の第１ガイド部３１１は、第１枠部３１の側壁から内側に向けて突出し、側壁に沿って延びる２つの凸部である。第１連結部４１は、開口部３５に挿入されると、第１ガイド部３１１である２つの凸部の間に配置される。そして、第１連結部４１は、第１ガイド部３１１である２つの凸部によって、上下方向の移動を規制されつつ、第１枠部３１に沿った方向に案内される。これにより、第１ガイド部３１１は、開口部３５に挿入された第１連結部４１が上下方向にずれることを抑制する。なお、上述したように、第１連結部４１の孔部と、第１枠部３１の孔部８とは、それぞれ対向するように配置され、第１枠部３１の外側からボルトが挿入される。このため、第１枠部３１が第１ガイド部３１１を備えることによって、第１連結部４１の孔部と、第１枠部３１の孔部８とを容易に位置合わせすることができる。その結果、第１連結部４１と第１枠部３１とを、より容易に接続させることができる。   Further, the first frame portion 31 of the present embodiment has a first guide portion 311 for guiding the first connecting portion 41 in a direction along the first frame portion 31.

The configuration of the second guide portion 322 is the same as that of the first guide portion 311, and thus description thereof is omitted.

上述したように、第１連結部４１および第２連結部４２は、回動部５０によって回動可能に繋がれる。このため、第１連結部４１および第２連結部４２の成す角度を、回動部５０を中心に任意に調整できる。そして、保持部６０は、当該角度を任意に調整した後に、第１連結部４１および第２連結部４２を保持する。これにより、保持部６０は、第１太陽光パネル２１および第２太陽光パネル２２の成す角度を任意の角度に調整しつつ、保持させることができる。その結果、本実施形態の連結装置１０によれば、複雑な形状の設置面に対しても、複数の太陽光パネルを連結しつつ設置することができる。   As described above, the first connecting portion 41 and the second connecting portion 42 are rotatably connected by the turning portion 50. For this reason, the angle formed by the first connecting portion 41 and the second connecting portion 42 can be arbitrarily adjusted about the rotating portion 50. Then, the holding unit 60 holds the first connection unit 41 and the second connection unit 42 after arbitrarily adjusting the angle. Accordingly, the holding unit 60 can hold the first solar panel 21 and the second solar panel 22 while adjusting the angle formed by the solar panel 21 to an arbitrary angle. As a result, according to the connection device 10 of the present embodiment, a plurality of solar panels can be connected and installed even on an installation surface having a complicated shape.
