Description

架台構造及び構造体Mounting structure and structure
　本発明は折り畳み自在の架台構造に関する。より詳しくは、構造物、建築物、遊具、家具に適用できる、４角形以上の２Ｎ（偶数）角形に展開される折り畳み自在の架台構造に関する。 The present invention relates to a foldable gantry structure. More specifically, the present invention relates to a foldable gantry structure that can be applied to a structure, a building, a playground equipment, or furniture, and that is expanded into a 2N (even number) square of four or more squares.
　従来、構造物、建築物等を支持するため、折り畳み自在な架台構造が知られている。折り畳み自在の架台構造は、たとえば構造物を凹凸や起伏のある不整地に一時的に設置する場合であっても、平坦に整地する必要がなく、自然環境保護の観点からも好ましく、また災害時の仮設住宅用の床構造としても利用可能であり、非常に注目されている。 Conventionally, a foldable gantry structure is known to support structures, buildings, and the like. The foldable gantry structure is preferable from the viewpoint of protecting the natural environment, and it is not necessary to level the ground even when the structure is temporarily installed on uneven or uneven terrain. It can also be used as a floor structure for temporary housing, and has attracted much attention.
　特許文献１には、３本の棒状部材からなる角錐立体形状の、上部フレームと下部フレームを組み合わせ、平坦な支持板を載置できる架台構造が提案されている。そして、折り畳み自在な架台構造は、構造物や、建築物等の支持だけを目的とするものではない。 Patent Document 1 proposes a gantry structure in which a flat support plate can be placed by combining an upper frame and a lower frame in a three-dimensional pyramid shape composed of three rod-shaped members. The foldable gantry structure is not intended only for supporting structures and buildings.
　特許文献２には、トランポリン等の遊具や運動器具において、跳躍部の構造が提案されている。さらに、特許文献３には、宇宙空間で使用される宇宙構造物が提案されている。この他にも、折り畳み自在な架台構造はテント等にも幅広く利用できる。 Patent Document 2 proposes a structure of a jumping portion in play equipment such as trampolines and exercise equipment. Furthermore, Patent Document 3 proposes a space structure used in outer space. In addition, the foldable base structure can be widely used for tents and the like.

　このように、広い分野に利用できる折り畳み式架台構造は、展開時に高重量の載置物を安定して支持でき、且つコンパクトに折り畳みできることに関して、益々高い性能が要求されている。しかしながら、特許文献１は、３本の棒状部材により支持板を３点支持する構造であり、必ずしも載置された支持板が十分に安定しているとは言えない。 As described above, the foldable gantry structure that can be used in a wide range of fields is required to have higher performance with respect to being able to stably support a heavy load when deployed and to be folded compactly. However, Patent Document 1 has a structure in which a support plate is supported at three points by three rod-shaped members, and it cannot be said that the placed support plate is sufficiently stable.
　また、特許文献２に提案された技術では、跳躍部を３つ折り程度に折り畳んで収容したに過ぎず、コンパクトな折り畳みとは言い難い。さらに、特許文献３は、無重力空間での利用を想定する構造であり、高重量を支持し得る高い剛性を有する構造とも言い難い。 Also, with the technique proposed in Patent Document 2, the jumping portion is only folded and accommodated in about three folds, and it is difficult to say that the folding is compact. Furthermore, Patent Document 3 is a structure that is supposed to be used in a weightless space, and it is difficult to say that the structure has high rigidity that can support high weight.
　本発明の目的は、上記事情に鑑み、４角形以上の２Ｎ角形に展開される折り畳み自在な架台構造において、展開状態の安定支持及び高い剛性と、折り畳み時のコンパクト性の両方を実現することである。 In view of the above circumstances, an object of the present invention is to realize both a stable support in a deployed state and high rigidity, and compactness at the time of folding in a foldable gantry structure that is developed into a 2N square or more square. is there.

It is arranged at each vertex of the 2N square and connects two adjacent housings at this vertex so that the housing can be rotated around an orthogonal axis perpendicular to both axes of the two housings. In addition, the connecting means for holding the ends of the two casings and the respective casings are divided so as to be rotatable about the axis of the casing relative to each other in a part of the length of the casing. It is possible to fold it into a columnar body as a whole by rotating the housing around the axis and pivoting the housing around the orthogonal axis so as to minimize the angle formed by two adjacent housings.

　第１軸心ＡＸ１は、上杆体２１０の中心を通る長尺方向に延びる上杆体２１０の中心軸である。上杆体２１０は長尺な柱状体であり、その長さは略等しい。上杆体２１０の長さ及び太さは、宇宙構造物、遊具、家具等の用途に応じて変更されるものであり、特に限定されない。 The first axis AX1 is the central axis of the upper casing 210 extending in the longitudinal direction passing through the center of the upper casing 210. The upper casing 210 is a long columnar body, and its length is substantially equal. The length and thickness of the upper casing 210 are not particularly limited, and are changed according to the use such as a space structure, play equipment, furniture, and the like.
　第１軸心ＡＸ１と直交する断面において、上杆体２１０は円形状を有する。上杆体２１０の断面形状は、限定されるものではなく、たとえば楕円形や矩形でもよい。上杆体２１０は、中実でもよく、たとえばパイプのように中空でもよい。上杆体２１０の材質は、剛性を有するものであれば限定されるものではなく、たとえば金属でもよく、木材や樹脂等でもよい。 In the cross section orthogonal to the first axis AX1, the upper casing 210 has a circular shape. The cross-sectional shape of the upper casing 210 is not limited and may be, for example, an ellipse or a rectangle. The upper casing 210 may be solid, and may be hollow like a pipe, for example. The material of the upper casing 210 is not limited as long as it has rigidity, and may be, for example, metal, wood, resin, or the like.
　第１連結手段２２０は正６角形の各頂点に１つ置きに配置される。第１連結手段２２０は、連結保持する上杆体２１０が直交軸ＡＸ２回りに回転自在となるように、一端部２１１を連結保持する。直交軸ＡＸ２は、連結保持する上杆体２１０の第１軸心ＡＸ１の両方と直交する軸である。 The first connecting means 220 is arranged at every other vertex of the regular hexagon.

　そして、上部構造２００は、第１連結手段２２０により、上杆体２１０を直交軸ＡＸ２回りに回転させ、上杆体２１０を互いに近接させつつ、回転手段２４０により、上杆体２１０を第１軸心ＡＸ１の回りに回転させながら折り畳むことにより、１本の柱状体に折り畳まれる。 The upper structure 200 rotates the upper casing 210 around the orthogonal axis AX2 by the first connecting means 220 and moves the upper casing 210 to the first axis AX1 by the rotating means 240 while bringing the upper casing 210 close to each other. By folding it around, it is folded into a single columnar body.
　上杆体２１０の正６角形の内側への折り畳みと、上杆体２１０を互いに近接させつつ第１軸心ＡＸ１回りに回転させながらの折り畳みとは、同時に行ってもよい。上部構造２００は、第１軸心ＡＸ１、直交軸ＡＸ２及び対角軸ＡＸ３の各軸回り以外の回転はしない。これにより、正６角形の展開形状、１本の柱状体である折り畳み形状、及びその途中形状以外の形状となることが制限される。 The folding of the upper casing 210 inside the regular hexagon and the folding while rotating the upper casing 210 around the first axis AX1 while being close to each other may be performed simultaneously. The upper structure 200 does not rotate except around the first axis AX1, the orthogonal axis AX2, and the diagonal axis AX3. This restricts the shape to be a shape other than a regular hexagonal unfolded shape, a folded shape that is a single columnar body, and an intermediate shape.
　第１の実施形態である架台構造１００において、上部構造２００の展開形状は正６角形に限定されるものではない。したがって、上部構造２００の展開形状は、たとえば正８角形、正１２角形でもよく、正２Ｎ角形（Ｎは３以上の整数）であればよい。 In the gantry structure 100 according to the first embodiment, the developed shape of the upper structure 200 is not limited to a regular hexagon. Therefore, the developed shape of the upper structure 200 may be, for example, a regular octagon or a regular dodecagon, and may be a regular 2N square (N is an integer of 3 or more).
　そして、展開形状が正２Ｎ角形（Ｎは３以上の整数）である場合、第１の実施形態の上部構造２００は、２Ｎ本の上杆体、Ｎ個の第１連結手段２２０、Ｎ個の第２連結手段２３０、２Ｎ個の回転手段２４０を備えればよい。 When the developed shape is a regular 2N square (N is an integer of 3 or more), the upper structure 200 of the first embodiment includes 2N upper casings, N first connecting means 220, and N first coupling means. Two connecting means 230 and 2N rotating means 240 may be provided.
　また、架台構造１００は、図１８に示すように、上部構造２００を覆う、正６角形と略同形の柔軟なシート２５０を備えてもよい。シート２５０の素材は、可撓性を有するものであれば限定されるものではく、たとえば布地や、ナイロンやビニール等の樹脂でもよい。また、シート２５０はメッシュを有するものでもよい。 Further, as shown in FIG. 18, the gantry structure 100 may include a flexible sheet 250 that covers the upper structure 200 and has substantially the same shape as a regular hexagon. The material of the sheet 250 is not limited as long as it has flexibility, and may be a fabric, a resin such as nylon or vinyl, for example. The sheet 250 may have a mesh.
　シート２５０は、展開状態において、正６角形の内側を覆うように、上杆体２１０に取り付けられる。シート２５０の各辺は、正６角形の辺と一致するように、上杆体２１０に固定される。シート２５０の固定方法は、ロープ、紐材、面ファスナ等の公知な方法でよい。 The sheet 250 is attached to the upper casing 210 so as to cover the inside of the regular hexagon in the unfolded state. Each side of the sheet 250 is fixed to the upper casing 210 so as to coincide with a regular hexagonal side. A fixing method of the sheet 250 may be a known method such as a rope, a string material, and a hook-and-loop fastener.
　また、上部構造２００の展開形状が正２Ｎ角形（Ｎは３以上の整数）である場合、シートの形状も正２Ｎ角形（Ｎは３以上の整数）とすればよい。上部構造２００は、高重量の部材等を載置させる場合、シート２５０の代わりに、金属や木材等の高い剛性を有する平板を支持板としてもよい。 Further, when the developed shape of the upper structure 200 is a regular 2N square (N is an integer of 3 or more), the shape of the sheet may be a regular 2N square (N is an integer of 3 or more). In the case of placing a heavy member or the like, the upper structure 200 may be a flat plate having high rigidity such as metal or wood instead of the sheet 250.
　上杆体２１０は、第１軸心方向ＡＸ１に伸縮自在であることが望ましい。展開中又は折り畳み中に、上杆体２１０を第１軸心方向ＡＸ１に収縮させることで、シート２５０の張力による各回転の抑制を低減できる。さらに、展開後に上杆体２１０を第１軸心方向ＡＸ１に伸展させることで、シート２５０に十分な張力を付与することもできる。具体的に、上杆体２１０は、第１軸心方向ＡＸ１に最大全長に対して３～１０パーセント程度伸縮自在であることが望ましい。 It is desirable that the upper casing 210 can be expanded and contracted in the first axial direction AX1. During expansion or folding, the upper casing 210 is contracted in the first axial direction AX1, so that suppression of each rotation due to the tension of the sheet 250 can be reduced. Furthermore, sufficient tension can be applied to the sheet 250 by extending the upper casing 210 in the first axial direction AX1 after deployment. Specifically, it is desirable that the upper casing 210 can expand and contract about 3 to 10 percent with respect to the maximum total length in the first axial direction AX1.
　再び図１～図８を参照して、中間構造３００について説明する。中間構造３００は、第１連結手段２２０及び第２連結手段２３０に、一端部３１１が回転自在に連結保持される６本の中間杆体３１０と、中間杆体３１０の他端部３１２を集束させて回転自在に連結保持する第３連結手段３２０とを備える。 The intermediate structure 300 will be described with reference to FIGS. 1 to 8 again. The intermediate structure 300 is rotated by focusing the six intermediate housings 310 whose one end portions 311 are rotatably connected and held on the first connecting device 220 and the second connecting device 230 and the other end portions 312 of the intermediate housing 310. And third connecting means 320 for freely connecting and holding.
　中間構造３００は、第３連結手段３２０を用いずに、他端部３１２同士を回転自在に直接的に連結保持してもよい。上部構造の展開形状が正２Ｎ角形（Ｎは３以上の整数）である場合、中間構造は、２Ｎ本の中間杆体３１０と、１個の第３連結手段３２０とを備えればよい。中間杆体３１０は、第１連結手段２２０に連結するＮ本のみ、又は第２連結手段２３０と連結するＮ本のみにしてもよい。 The intermediate structure 300 may connect and hold the other end portions 312 directly and rotatably without using the third connecting means 320. When the developed shape of the superstructure is a regular 2N square (N is an integer of 3 or more), the intermediate structure may include 2N intermediate housings 310 and one third connecting means 320. The intermediate casing 310 may include only N links connected to the first connecting means 220 or only N links connected to the second connecting means 230.
　中間杆体３１０は長尺な柱状体である。また、中間杆体３１０は略等しい長さを有する。中間杆体３１０の長さは、上杆体２１０と同様に、特に限定されるものではない。中間杆体３１０の軸心と直交する断面において、中間杆体３１０は円形状である。中間杆体３１０の軸心とは中間杆体３１０の長尺方向に延びる中心軸である。 The intermediate housing 310 is a long columnar body. Further, the intermediate casing 310 has substantially the same length. The length of the intermediate casing 310 is not particularly limited as is the case with the upper casing 210. In the cross section orthogonal to the axis of the intermediate casing 310, the intermediate casing 310 has a circular shape. The axis of the intermediate casing 310 is a central axis extending in the longitudinal direction of the intermediate casing 310.
　中間杆体３１０の断面形状は、上杆体２１０と同様に、特に限定されるものではなく、楕円形状や矩形形状でもよい。中間杆体３１０は、中実でもよく、パイプのような中空でもよい。中間杆体３１０の材質は、剛性を有するものであれば限定されるものではなく、たとえば金属でもよく、木材や樹脂等でもよい。 The cross-sectional shape of the intermediate casing 310 is not particularly limited, as with the upper casing 210, and may be an elliptical shape or a rectangular shape. The intermediate housing 310 may be solid or hollow such as a pipe. The material of the intermediate casing 310 is not limited as long as it has rigidity, and may be, for example, metal, wood, resin, or the like.
　中間杆体３１０は、上杆体２１０よりも長いことが望ましい。これにより、第３連結手段３２０は正６角形の中心を通る法線上に位置する。そして、架台構造１００は、展開状態において正６角形の下方に、上杆体２１０及び中間杆体３１０からなる６つのトラス構造を構成できる。上部構造の展開形状が正２Ｎ角形（Ｎは３以上の整数）である場合、架台構造は２Ｎ個（Ｎは３以上の整数）のトラス構造を有し剛性を高められる。 The intermediate casing 310 is preferably longer than the upper casing 210. Thereby, the 3rd connection means 320 is located on the normal line which passes along the center of a regular hexagon. The gantry structure 100 can constitute six truss structures including the upper casing 210 and the intermediate casing 310 below the regular hexagon in the unfolded state. When the developed shape of the superstructure is a regular 2N square (N is an integer of 3 or more), the gantry structure has 2N truss structures (N is an integer of 3 or more), and the rigidity is increased.
　６本の中間杆体３１０のうち、３本の中間杆体３１０の一端部３１１は、第１連結手段２２０に着脱自在に連結保持される。残りの３本の中間杆体３１０の一端部３１１は、第２連結手段２３０に着脱自在に連結保持される。他端部３１２は、第３連結手段３２０に放射状に等角度で連結保持される。 Among the six intermediate casings 310, one end portions 311 of the three intermediate casings 310 are detachably connected to the first connecting means 220. One end portion 311 of the remaining three intermediate casings 310 is detachably connected to the second connecting means 230. The other end 312 is connected and held radially to the third connecting means 320 at an equal angle.
　第１連結手段２２０及び第２連結手段２３０において、一端部３１１は中間杆体３１０の軸心と直交する回転軸の回りに回転自在である。また、第３連結手段３２０において、他端部３１２は中間杆体３１０の軸心と直交する回転軸の回りに回転自在である。 In the first connecting means 220 and the second connecting means 230, the one end 311 is rotatable around a rotation axis orthogonal to the axis of the intermediate casing 310. In the third connecting means 320, the other end 312 is rotatable around a rotation axis that is orthogonal to the axis of the intermediate housing 310.
　中間構造３００は、第１連結手段２２０から一端部３１１を着脱し、その後、上部構造２００を折り畳むことにより、その折り畳みに追従して、第２連結手段２３０に連結した中間杆体３１０が正６角形の内側に向かって互いに近接するように折り畳まれる。 In the intermediate structure 300, one end 311 is attached to and detached from the first connecting means 220, and then the upper structure 200 is folded, so that the intermediate casing 310 connected to the second connecting means 230 follows the folding, and is a regular hexagon. Folded close to each other toward the inside.
　そして、第１連結手段２２０より着脱された中間杆体３１０を正６角形の内側に向かって互いに近接するように折り畳むことにより、中間構造３００も上部構造２００と一緒に１本の柱状態に折り畳みできる。 Then, the intermediate structure 300 can be folded together with the upper structure 200 into a single pillar state by folding the intermediate casing 310 detached from the first connecting means 220 so as to be close to each other toward the inside of the regular hexagon. .
　下部構造４００について説明する。下部構造４００は、６本の下杆体４１０と、下杆体４１０と第３連結手段３２０とを結合する線材４２０とを備える。下杆体４１０の一端部４１１は中間杆体３１０と回転自在に連結されている。また、下杆体４１０の他端部４１２は、線材４２０に結合され地上に設置される。 The lower structure 400 will be described. The lower structure 400 includes six lower casings 410 and a wire rod 420 that couples the lower casings 410 and the third connecting means 320. One end 411 of the lower casing 410 is rotatably connected to the intermediate casing 310. Further, the other end portion 412 of the lower casing 410 is coupled to the wire 420 and installed on the ground.
　下杆体４１０の本数は、特に限定されるものではないが、架台構造１００を安定させるため、３本以上であることが望ましい。下杆体４１０は、地上に向けて斜め下方に延び、且つ等間隔に配置されていることが望ましい。線材４２０は、剛性を有するものであれば限定されず、たとえばワイヤやロープ等であってもよい。また、下杆体４１０は伸縮自在に調整可能である。これにより、起伏が激しい不整地であっても、架台構造１００を安定して設置できる。 The number of the lower casing 410 is not particularly limited, but is preferably three or more in order to stabilize the gantry structure 100. The lower casing 410 desirably extends obliquely downward toward the ground and is arranged at equal intervals. The wire 420 is not limited as long as it has rigidity, and may be, for example, a wire or a rope. Further, the lower casing 410 can be adjusted to be extendable. Thereby, the gantry structure 100 can be stably installed even on rough terrain.
　折り畳み時において、下杆体４１０は、中間杆体３１０に近接するように折り畳まれ、線材４２０も追従して撓むため、下部構造４００も、上部構造２００及び中間構造３００と一緒に１本の柱状態に折り畳みできる。 At the time of folding, the lower casing 410 is folded so as to be close to the intermediate casing 310, and the wire 420 also follows and bends. Therefore, the lower structure 400 is also in a single column state together with the upper structure 200 and the intermediate structure 300. Can be folded into
　第１連結手段２２０による、一端部２１１及び他端部３１２との連結構造について説明する。図１９Ａは、架台構造１００の第１連結手段２２０の付近を拡大した斜視図である。 A connection structure between the first end 211 and the other end 312 by the first connecting means 220 will be described. FIG. 19A is an enlarged perspective view of the vicinity of the first connecting means 220 of the gantry structure 100.
　第１連結手段２２０は、同一部品である２つの第１本体２２０Ａを螺子等の公知手段により組み合わせた構造である。図１９Ｂは、第１本体２２０Ａの片方のみを図示した分解斜視図である。 The first connecting means 220 has a structure in which two first main bodies 220A which are the same parts are combined by a known means such as a screw. FIG. 19B is an exploded perspective view illustrating only one side of the first main body 220A.
　第１本体２２０Ａは一端部２１１を収容する第１切欠部２２１を左右両側に有する。第１切欠部２２１の底面には、直交軸ＡＸ２方向に延びる、円柱形状の凸部２２１Ａが突設されている。 The first main body 220A has first cutout portions 221 for accommodating the one end portions 211 on both the left and right sides. On the bottom surface of the first cutout portion 221, a cylindrical convex portion 221 </ b> A extending in the direction of the orthogonal axis AX <b> 2 protrudes.
　一端部２１１は半円形の先端を有している。当該半円の中心には、凸部２２１Ａと略同径の貫通孔２１１Ａが形成されている。また、第１切欠部２２１は、一端部２１１の先端径と等しい曲率半径を有する曲側面２２１Ｂ、曲側面２２１Ｂの両側から連続する平坦な平側面２２１Ｃを有している。 The one end 211 has a semicircular tip. At the center of the semicircle, a through-hole 211A having the same diameter as the convex portion 221A is formed. The first cutout 221 has a curved side 221B having a radius of curvature equal to the tip diameter of the one end 211, and a flat flat side 221C continuous from both sides of the curved side 221B.
　一端部２１１は、凸部２２１Ａを貫通孔２１１Ａに嵌め合せることにより、第１連結手段２２０に対して回転自在である。一端部２１１が摺動できる程度に、凸部２２１Ａと貫通孔２１１Ａとはクリアランスを有し、曲側面２２１Ｂと一端部２１１もクリアランスを有している。 The one end portion 211 is rotatable with respect to the first connecting means 220 by fitting the convex portion 221A into the through hole 211A. The convex portion 221A and the through hole 211A have a clearance so that the one end portion 211 can slide, and the curved side surface 221B and the one end portion 211 also have a clearance.
　一端部２１１は、平側面２２１Ｃと当接することにより、折り畳み時の回転角度が制限される。一端部２１１は、外側の平側面２２１Ｃと当接することにより、展開時の回転角度が制限される。一端部２１１は直交軸ＡＸ２回りの回転角度は制限されている。 The one end portion 211 is in contact with the flat side surface 221C, so that the rotation angle at the time of folding is limited. The one end portion 211 is in contact with the outer flat side surface 221C, so that the rotation angle at the time of deployment is limited. The rotation angle of the one end 211 around the orthogonal axis AX2 is limited.
　平側面２２１Ｃは、折り畳み時に第１軸心ＡＸ１同士が互いに平行となるように形成されている。平側面２２１Ｃは、展開時に第１軸心ＡＸ１同士が互いに１２０度の角度をなすように形成されている。上部構造の展開形状が正２Ｎ角形（Ｎは３以上の整数）である場合、平側面２２１Ｃは、展開時に第１軸心ＡＸ１同士が互いに、（１８０－３６０／２Ｎ）度の角度をなすように形成すればよい。 The flat side surface 221C is formed such that the first axial centers AX1 are parallel to each other when folded. The flat side surface 221C is formed such that the first axes AX1 form an angle of 120 degrees with each other when deployed. When the developed shape of the superstructure is a regular 2N square (N is an integer of 3 or more), the flat side surface 221C has an angle of (180-360 / 2N) degrees between the first axial centers AX1 when deployed. What is necessary is just to form.
　第１連結手段２２０は、一端部２１１の直交軸ＡＸ２の回りの回転をロックする第１ロック機構を有してもよい。第１ロック機構は、第１本体２２０Ａと一端部２１１とをピン等で結合する公知な機構でよい。 The first connecting means 220 may have a first lock mechanism that locks the rotation of the one end 211 around the orthogonal axis AX2. The first lock mechanism may be a known mechanism that couples the first main body 220A and the one end 211 with a pin or the like.
　図１９Ａ及び図１９Ｂにおいて、中間杆体３１０の一端部３１１は図示を省略している。図１９Ａ及び図１９Ｂにおいて、一端部３１１は第２軸心ＡＸ４のみを図示する。第２軸心ＡＸ４は、中間杆体３１０の長尺方向に延びる中心軸である。 19A and 19B, one end portion 311 of the intermediate casing 310 is not shown. In FIG. 19A and FIG. 19B, the one end portion 311 illustrates only the second axis AX4. The second axis AX4 is a central axis extending in the longitudinal direction of the intermediate casing 310.
　第１本体２２０Ａには、左右の第１切欠部２２１の間に、不図示の一端部３１１を収容する第１中間切欠部２２２を有する。また、不図示の一端部３１１は、第２軸心ＡＸ４と直交する段付き円柱状である。 The first main body 220 </ b> A has a first intermediate notch portion 222 that houses one end 311 (not shown) between the left and right first notch portions 221. Further, one end 311 (not shown) has a stepped columnar shape orthogonal to the second axis AX4.
　第１中間切欠部２２２は、不図示の一端部３１１と略同径の曲率半径である内周面を有する。不図示の一端部３１１は第１中間切欠部２２２内で摺動可能である。これにより、不図示の一端部３１１は、第１連結手段２２０に対して、回転軸ＡＸ５の回りに回転自在である。回転軸ＡＸ５は第２軸心ＡＸ４と直交する軸である。 The first intermediate notch portion 222 has an inner peripheral surface having a radius of curvature substantially the same as that of the not-shown one end portion 311. One end 311 (not shown) is slidable in the first intermediate notch 222. Thereby, the one end portion 311 (not shown) is rotatable around the rotation axis AX5 with respect to the first connecting means 220. The rotation axis AX5 is an axis orthogonal to the second axis AX4.
　第１の実施形態において、一端部２１１側を孔構造とし、第１本体２２０Ａ側を突起構造としたが、一端部２１１を突起構造、第１本体２２０Ａを孔構造としてもよい。同様に、第１本体２２０Ａ側を孔構造、一端部３１１側を突起構造としたが、第１本体２２０Ａ側を突起構造、一端部３１１側を孔構造としてもよい。 In the first embodiment, the one end 211 side has a hole structure and the first main body 220A side has a protruding structure, but the one end 211 may have a protruding structure and the first main body 220A may have a hole structure. Similarly, although the first body 220A side has a hole structure and the one end 311 side has a protruding structure, the first body 220A side may have a protruding structure and the one end 311 side have a hole structure.
　第１の実施形態において、回転手段２４０は、一端部２１１を上杆体２１０の本体に対して第１軸心ＡＸ１の回りに回転可能とする機構である。回転手段２４０は、一端部２１１側に第１軸心ＡＸ１方向の突起あるいは窪み、本体側に第１軸心ＡＸ１方向の窪みあるいは突起からなる公知な機構でよい。なお、回転手段２４０は、第１切欠部２２１を有する部分を第１軸心ＡＸ１方向に回転できるように、第１本体２２０Ａを分割して構成してもよい。 In the first embodiment, the rotating means 240 is a mechanism that allows the one end 211 to rotate around the first axis AX1 with respect to the main body of the upper casing 210. The rotating means 240 may be a known mechanism having a projection or depression in the direction of the first axis AX1 on the one end 211 side and a depression or projection in the direction of the first axis AX1 on the main body side. The rotating means 240 may be configured by dividing the first main body 220A so that the portion having the first notch 221 can be rotated in the direction of the first axis AX1.
　第２連結手段２３０による、他端部２１２及び一端部３１１との連結構造について説明する。図２０Ａは、架台構造１００の第２連結手段２３０の付近を拡大した斜視図である。 A connection structure between the other end portion 212 and the one end portion 311 by the second connecting means 230 will be described. FIG. 20A is an enlarged perspective view of the vicinity of the second connecting means 230 of the gantry structure 100.
　第２連結手段２３０は、同一部品である２つの第２本体２３０Ａを螺子等の公知手段により組み合わせた構造である。図２０Ａは、第２本体２３０Ａの片方のみを図示した分解斜視図である。 The second connecting means 230 has a structure in which two second bodies 230A which are the same parts are combined by a known means such as a screw. FIG. 20A is an exploded perspective view illustrating only one side of the second main body 230A.
　第２本体２３０Ａは他端部２１２を収容する第２切欠部２３１を左右両側に有する。他端部２１２は第１軸心ＡＸ１と３０度の角度をなす、段付きの円柱状である。そして、第２切欠部２３１も、展開状態において第１軸心ＡＸ１と３０度の角度をなすように対角軸ＡＸ３方向に形成されている。 The second main body 230A has second cutout portions 231 for accommodating the other end portion 212 on both the left and right sides. The other end 212 has a stepped columnar shape that forms an angle of 30 degrees with the first axis AX1. The second notch 231 is also formed in the direction of the diagonal axis AX3 so as to form an angle of 30 degrees with the first axis AX1 in the deployed state.
　他端部２１２は、第２連結手段２３０により、展開状態から上杆体２１０が正６角形の内側となるまで、対角軸ＡＸ３回りに１８０度回転できる。そして、他端部２１２は、展開した位置及び１８０度回転して位置で対角軸ＡＸ３回りの回転が制限されることが望ましい。他端部２１２は、他端部２１２の外周面上に凸部を設け、展開した位置及び１８０度回転して位置で凸部が第２本体２３０Ａと当接することにより、対角軸ＡＸ３回りの角度が制限してもよい。 The other end portion 212 can be rotated 180 degrees around the diagonal axis AX3 by the second connecting means 230 until the upper casing 210 is inside the regular hexagon from the deployed state. And it is desirable that the other end portion 212 is rotated by 180 degrees and the rotation about the diagonal axis AX3 is limited at the position where the other end portion 212 is rotated. The other end portion 212 is provided with a convex portion on the outer peripheral surface of the other end portion 212, rotated by 180 degrees, and the convex portion comes into contact with the second main body 230A at the position, thereby rotating around the diagonal axis AX3. The angle may be limited.
　第１連結手段２２０又は第２連結手段２３０の少なくともいずれかにおいて、展開位置及び折り畳み位置の、一端部２１１の直交軸ＡＸ２回りの回転角度又は他端部２１２の対角軸ＡＸ３回りの回転角度を制限することにより、上部構造２００の展開及び折り畳みの各形状を正確に再現できる。 In at least one of the first connecting means 220 and the second connecting means 230, the rotation angle of the one end portion 211 around the orthogonal axis AX2 or the rotation angle around the diagonal axis AX3 of the other end portion 212 at the deployed position and the folded position is set. By restricting, each shape of expansion and folding of the superstructure 200 can be accurately reproduced.
　上部構造の展開形状が正２Ｎ角形（Ｎは３以上の整数）である場合、他端部２１２は第１軸心ＡＸ１と（１８０／２Ｎ）度の角度をなせばよい。また、第２切欠部２３１も、第１軸心ＡＸ１と（１８０／２Ｎ）度の角度をなす対角軸ＡＸ３の方向に形成すればよい。 When the developed shape of the superstructure is a regular 2N square (N is an integer of 3 or more), the other end 212 may form an angle of (180 / 2N) degrees with the first axis AX1. The second cutout 231 may also be formed in the direction of the diagonal axis AX3 that forms an angle of (180 / 2N) degrees with the first axis AX1.
　第２切欠部２３１は、他端部２１２と略同径の曲率半径を有する内曲面を有している。他端部２１２ができる程度に、第２切欠部２３１と他端部２１２はクリアランスを有している。 The second cutout portion 231 has an inner curved surface having a radius of curvature substantially the same diameter as the other end portion 212. The second notch 231 and the other end 212 have a clearance to the extent that the other end 212 can be formed.

　次に本発明に係る第２の実施形態の架台構造１０１について以下図面を用いて詳細に説明する。図２５は、上部構造２０１からなる架台構造１０１の展開状態及び折り畳み状態をそれぞれ示す図、図２６は、図２５の架台構造の展開及び折り畳みの途中を示す図である。なお、図２６は、説明の便宜上、各部品の構成を簡略化している。 Next, the gantry structure 101 according to the second embodiment of the present invention will be described in detail with reference to the drawings. FIG. 25 is a diagram showing the unfolded state and the folded state of the gantry structure 101 formed of the upper structure 201, and FIG. 26 is a diagram showing the middle of the unfolding and folding of the gantry structure of FIG. In FIG. 26, for convenience of explanation, the configuration of each component is simplified.
　架台構造１０１は、第１の実施形態の架台構造１００と同様に、上部構造２０１、上部構造２０１の下方で上部構造２０１を支持する中間構造３００、中間構造３００と連結し地上に設置される下部構造４００とを備えていてもよい。また、架台構造１０１は、図２５に示すように、上部構造２０１を直接地上に設置して、上部構造２０１のみを架台構造としてもよい。また、架台構造１０１は、第１の実施形態の図１０と同様に、宇宙空間や、水や油等の液体空間において、上部構造２０１と中間構造３００とを架台構造としてもよい。 The gantry structure 101 is similar to the gantry structure 100 of the first embodiment. The upper structure 201, the intermediate structure 300 that supports the upper structure 201 below the upper structure 201, and the lower structure that is connected to the intermediate structure 300 and installed on the ground. Structure 400 may be provided. In addition, as shown in FIG. 25, the gantry structure 101 may be configured such that the upper structure 201 is directly installed on the ground and only the upper structure 201 is a gantry structure. Further, the gantry structure 101 may have the gantry structure of the upper structure 201 and the intermediate structure 300 in the outer space or a liquid space such as water or oil, as in FIG. 10 of the first embodiment.
　主に図２５，図２６を参照して、上部構造２０１を説明する。なお図２５、図２６の上部構造２０１は、第１の実施形態の図９の上部構造２００の第２連結手段２３０を第１連結手段２２０に変更したものであり、同様の箇所について同じ符号を付与する。なお第１連結手段２２０は本発明の連結手段に相当する。 The upper structure 201 will be described mainly with reference to FIGS. The upper structure 201 in FIGS. 25 and 26 is obtained by changing the second connecting means 230 of the upper structure 200 in FIG. 9 of the first embodiment to the first connecting means 220, and the same reference numerals are used for the same portions. Give. The first connecting means 220 corresponds to the connecting means of the present invention.
　上部構造２０１は、６本の上杆体を連結して平板状の正６角形をなすように展開されており、６本の上杆体２１０と、正６角形の各頂点に配置され、頂点において隣接する２本の上杆体２１０の一端部２１１同士を連結保持する６個の第１連結手段２２０と、上杆体２１０を第１軸心ＡＸ１の回りに回転自在にさせる６個の回転手段２４０とを備える。 The upper structure 201 is developed to connect six upper casings to form a flat regular hexagon, and is arranged at each of the six upper casings 210 and the apexes of the regular hexagon, and adjacent to each other at the apexes. Six first connecting means 220 for connecting and holding one end portions 211 of the two upper casings 210 and six rotating means 240 for allowing the upper casing 210 to rotate about the first axis AX1. Prepare.
　第１軸心ＡＸ１は、上杆体２１０の中心を通る長尺方向に延びる上杆体２１０の中心軸である。上杆体２１０は長尺な柱状体であり、その長さは略等しい。上杆体２１０の長さ及び太さは、宇宙構造物、遊具、家具等の用途に応じて変更されるものであり、特に限定されない。 The first axis AX1 is the central axis of the upper casing 210 extending in the longitudinal direction passing through the center of the upper casing 210. The upper casing 210 is a long columnar body, and its length is substantially equal. The length and thickness of the upper casing 210 are not particularly limited, and are changed according to the use such as a space structure, play equipment, furniture, and the like.
　第１軸心ＡＸ１と直交する断面において、上杆体２１０は円形状を有する。上杆体２１０の断面形状は、限定されるものではなく、たとえば楕円形や矩形でもよい。上杆体２１０は、中実でもよく、たとえばパイプのように中空でもよい。上杆体２１０の材質は、剛性を有するものであれば限定されるものではなく、たとえば金属でもよく、木材や樹脂等でもよい。 In the cross section orthogonal to the first axis AX1, the upper casing 210 has a circular shape. The cross-sectional shape of the upper casing 210 is not limited and may be, for example, an ellipse or a rectangle. The upper casing 210 may be solid, and may be hollow like a pipe, for example. The material of the upper casing 210 is not limited as long as it has rigidity, and may be, for example, metal, wood, resin, or the like.
　第１連結手段２２０は正６角形の各頂点に配置される。第１連結手段２２０は、連結保持する上杆体２１０が直交軸ＡＸ２回りに回転自在となるように、一端部２１１を連結保持する。直交軸ＡＸ２は、連結保持する上杆体２１０の第１軸心ＡＸ１の両方と直交する軸である。隣接する２本の上杆体２１０が直交軸ＡＸ２回りに回転自在となることにより、隣接する２本の上杆体２１０は、この２本の上杆体２１０がなす角度を最小（略０度）にする方向及び最大（略１２０度）にする方向に移動可能となる。 The first connecting means 220 is arranged at each vertex of the regular hexagon. The first connecting means 220 connects and holds the one end portion 211 so that the upper casing 210 to be connected and held can rotate about the orthogonal axis AX2. The orthogonal axis AX2 is an axis orthogonal to both the first axis AX1 of the upper casing 210 that is connected and held. Since the two adjacent upper casings 210 are rotatable around the orthogonal axis AX2, the two adjacent upper casings 210 minimize the angle formed by the two upper casings 210 (approximately 0 degrees). It becomes possible to move in the direction and the direction that makes the maximum (approximately 120 degrees).
　回転手段２４０は、一端部２１１の近傍で、上杆体２１０の本体を第１軸心ＡＸ１の回りに回転自在にする。すなわち回転手段２４０は、第１連結手段２２０を上杆体２１０の本体に対して第１軸心ＡＸ１の回りに回転可能とする機構であり、第１の実施形態の回転手段２４０と同じものである。なお、第２の実施形態においては、第１の実施形態と同様に、各上杆体２１０の本体を、この上杆体２１０の両端部２１１を保持する２つの第１連結手段２２０の両方に対して第１軸心ＡＸ１回りに回転可能な構成、すなわち各上杆体２１０の両端部２１１の近傍に回転手段２４０を有する構成としたが、本発明においては、各上杆体２１０の本体を、この上杆体２１０の両端部２１１を保持する２つの第１連結手段２２０の少なくとも一方に対して第１軸心ＡＸ１回りに回転可能な構成であればよく、たとえば、上杆体２１０の一方の端部（一端部）２１１の近傍のみが回転手段２４０を有する構成としてもよい。 The rotating means 240 makes the main body of the upper casing 210 rotatable around the first axis AX1 in the vicinity of the one end 211. That is, the rotating means 240 is a mechanism that allows the first connecting means 220 to rotate about the first axis AX1 with respect to the main body of the upper casing 210, and is the same as the rotating means 240 of the first embodiment. . In the second embodiment, as in the first embodiment, the main body of each upper housing 210 is connected to both of the two first connecting means 220 that hold both end portions 211 of the upper housing 210. Although it is set as the structure which can rotate to the surroundings of 1st axis AX1, ie, the structure which has the rotation means 240 in the vicinity of the both ends 211 of each upper casing 210, in this invention, the main body of each upper casing 210 is this upper casing. Any structure that can rotate around the first axis AX1 with respect to at least one of the two first connecting means 220 holding the two end portions 211 of the 210 may be used. For example, one end portion (one end portion) of the upper casing 210 may be used. ) Only the vicinity of 211 may have the rotating means 240.
　上部構造２０１は、図２５の上図に示す展開状態から、回転手段２４０により、上杆体２１０を第１軸心ＡＸ１回りに回転させながら、第１連結手段２２０により、隣接する２本の上杆体２１０のなす角度が最小になるように、上杆体２１０を直交軸ＡＸ２回りに枢動すると、第１連結手段２２０が１つ置きに起こされた第２６図に示す状態になる。 The upper structure 201 has two adjacent upper casings by the first connecting means 220 while rotating the upper casing 210 around the first axis AX1 by the rotating means 240 from the expanded state shown in the upper diagram of FIG. When the upper casing 210 is pivoted about the orthogonal axis AX2 so that the angle formed by 210 is minimized, the state shown in FIG. 26 is obtained in which every other first connecting means 220 is raised.
　そして、上部構造２０１は、図２６の状態より、上杆体２１０同士をさらに近づけ、最終的には、１つ置きの３つの第１連結手段２２０をそれぞれ近接させることにより、全体として１本の柱状体に折り畳まれ、図２５の下図に示す折り畳み状態になる。 Then, the upper structure 201 further brings the upper casings 210 closer to each other than in the state of FIG. 26, and finally makes every other three first connecting means 220 close to each other, so that one columnar shape as a whole. Folded to the body, the folded state shown in the lower part of FIG.
　なお、上部構造２０１は、第１軸心ＡＸ１及び直交軸ＡＸ２の各軸回り以外に上杆体２１０を回転させる構造を有しない。これにより、正６角形の展開形状、１本の柱状体である折り畳み形状、及びその途中形状からなる所定形状以外の形状を有することが制限される。 In addition, the upper structure 201 does not have a structure for rotating the upper casing 210 other than around the first axis AX1 and the orthogonal axis AX2. This restricts having a regular hexagonal unfolded shape, a folded shape that is a single columnar body, and a shape other than a predetermined shape consisting of a halfway shape.
　また、架台構造１０１は、図２７に示すように、上部構造２０１を覆う、正６角形と略同形の柔軟なシート２５０を備えてもよい。シート２５０の素材は、可撓性を有するものであれば限定されるものではく、たとえば布地や、ナイロンやビニール等の樹脂でもよい。また、シート２５０はメッシュを有するものでもよい。 Further, as shown in FIG. 27, the gantry structure 101 may include a flexible sheet 250 that covers the upper structure 201 and has substantially the same shape as a regular hexagon. The material of the sheet 250 is not limited as long as it has flexibility, and may be a fabric, a resin such as nylon or vinyl, for example. The sheet 250 may have a mesh.
　シート２５０は、展開状態において、正６角形の内側を覆うように、上杆体２１０に取り付けられる。シート２５０の各辺は、各上杆体２１０が、各々の軸心回りに回転可能であるように上杆体２１０に懸架される。各上杆体２１０が、各々の軸心回りに回転可能であれば、シート２５０の各辺が上杆体２５０に直接固定されていてもよいし、シート２５０の各辺が各々筒部を有し、この筒部に上杆体２１０を挿通させるようにしてもよいし、シート２５０の各辺と上杆体２１０とがたとえばロープ、紐材、面ファスナ等の別の部材によって結ばれていてもよいし、公知な方法でよい。なお、シート２５０は、可撓性を有しているので、上杆体２１０に取り付けられた状態で、上部構造２０１を折り畳んだり、展開させたりすることができる。そして、上部構造２０１が折り畳まれた状態（図２５の下図参照）及び折り畳み又は展開の途中の状態（図２６参照）のときには、シート２５０には張力が付与されず、上部構造２０１の展開動作に伴い、シート２５０に張力が徐々に付与され、展開状態（図２５の上図参照）になったときには、大きな荷重にも撓まず平面を維持するに十分な張力がシート２５０に付与される。 The sheet 250 is attached to the upper casing 210 so as to cover the inside of the regular hexagon in the unfolded state. Each side of the seat 250 is suspended from the upper casing 210 so that each upper casing 210 can rotate around its respective axis. As long as each upper casing 210 is rotatable around its respective axis, each side of the sheet 250 may be directly fixed to the upper casing 250, and each side of the sheet 250 has a cylindrical portion, The upper casing 210 may be inserted through the cylindrical portion, or each side of the sheet 250 and the upper casing 210 may be connected by another member such as a rope, a string member, a hook-and-loop fastener, A known method may be used. Since the sheet 250 has flexibility, the upper structure 201 can be folded or unfolded while being attached to the upper casing 210. When the upper structure 201 is folded (see the lower diagram in FIG. 25) and in the middle of folding or unfolding (see FIG. 26), no tension is applied to the sheet 250, and the upper structure 201 is unfolded. Accordingly, when the tension is gradually applied to the sheet 250 and the sheet 250 is in a developed state (see the upper diagram of FIG. 25), sufficient tension is applied to the sheet 250 to maintain a flat surface without being bent even by a large load.
　また、上部構造の展開形状が２Ｎ角形（Ｎは２以上の整数）である場合、シートの形状も２Ｎ角形（Ｎは２以上の整数）とすればよい。上部構造２００は、高重量の部材等を載置させる場合、シート２５０の代わりに、金属や木材等の高い剛性を有する平板を支持板としてもよい。 Further, when the developed shape of the superstructure is a 2N square (N is an integer of 2 or more), the shape of the sheet may be a 2N square (N is an integer of 2 or more). In the case of placing a heavy member or the like, the upper structure 200 may be a flat plate having high rigidity such as metal or wood instead of the sheet 250.
　上杆体２１０は、第１軸心方向ＡＸ１に伸縮自在であることが望ましい。展開中又は折り畳み中に、上杆体２１０を第１軸心方向ＡＸ１に収縮させることで、シート２５０の張力による各回転の抑制を低減できる。さらに、展開後に上杆体２１０を第１軸心方向ＡＸ１に伸展させることで、シート２５０に十分な張力を付与することもできる。具体的に、上杆体２１０は、第１軸心方向ＡＸ１に最大全長に対して３～１０パーセント程度伸縮自在であることが望ましい。 It is desirable that the upper casing 210 can be expanded and contracted in the first axial direction AX1. During expansion or folding, the upper casing 210 is contracted in the first axial direction AX1, so that suppression of each rotation due to the tension of the sheet 250 can be reduced. Furthermore, sufficient tension can be applied to the sheet 250 by extending the upper casing 210 in the first axial direction AX1 after deployment. Specifically, it is desirable that the upper casing 210 can expand and contract about 3 to 10 percent with respect to the maximum total length in the first axial direction AX1.
　なお、第２の実施形態の第１連結手段２２０は、上述したような構成としたが、直交軸ＡＸ２回りに上杆体２１０が回転自在となるように、隣接する２本の上杆体２１０の一端部２１１同士を保持することができれば、他の構成であってもよい。ここで図２８に第２の実施形態の第１連結手段２２０－２の付近を拡大した斜視図を示す。 In addition, although the 1st connection means 220 of 2nd Embodiment set it as the above-mentioned structure, one end of two adjacent upper casings 210 so that the upper casing 210 could rotate around the orthogonal axis AX2. Any other configuration may be used as long as the units 211 can be held. Here, FIG. 28 shows an enlarged perspective view of the vicinity of the first connecting means 220-2 of the second embodiment.
　第１連結手段２２０－２は、図２８に示すように、同一部品である２つの第１本体２２０Ｂを組み合わせた構造である。第１本体２２０Ｂは上杆体２１０の一端部２１１が固定される角状部２２３と、この角状部２２３の略半分の厚さに形成され、角状部２２３から延びる円形部２２４とを備える。円形部２２４は略中央に孔２２５を有しており、この孔２２５の中心が直交軸ＡＸ２と略一致するように構成される。 As shown in FIG. 28, the first connecting means 220-2 has a structure in which two first main bodies 220B that are the same parts are combined. The first main body 220 </ b> B includes a rectangular portion 223 to which one end portion 211 of the upper casing 210 is fixed, and a circular portion 224 that is formed to have a thickness that is substantially half of the rectangular portion 223 and extends from the rectangular portion 223. The circular portion 224 has a hole 225 at substantially the center, and the center of the hole 225 is configured to substantially coincide with the orthogonal axis AX2.
　なお第２の実施形態の第１連結手段２２０－２を採用するときには、上杆体２１０の一端部２１１は上杆体２１０の本体と同じように、第１軸心ＡＸ１と直交する断面の形状が円形状の円柱体とする。なお一端部２１１の形状は、円柱体に限られるものではなく、円筒状であっても角柱状であってもよい。 When the first connecting means 220-2 of the second embodiment is adopted, the one end portion 211 of the upper casing 210 has a circular cross section perpendicular to the first axis AX1, like the main body of the upper casing 210. A cylindrical body having a shape. Note that the shape of the one end portion 211 is not limited to a cylindrical body, and may be cylindrical or prismatic.
　角状部２２３には、一端部２１１が固定される端面に一端部２１１が嵌合する凹部が形成されており、この凹部に一端部２１１が嵌合することにより第１本体２２０Ｂが一端部２１１を保持する。 The rectangular portion 223 is formed with a concave portion in which the one end portion 211 is fitted to an end surface to which the one end portion 211 is fixed, and the first main body 220B is fitted to the one end portion 211 by fitting the one end portion 211 into the concave portion. Hold.
　上記のように構成された第１本体２２０Ｂの円形部２２４を重ね合わせ、重ね合わせた２つの円形部２２４の孔２２５に不図示のピンを挿入する。なおピンの両端には、円形部２２４がピンから抜け出さないように抜け止めを取り付けておく。このとき抜け止めは、２つの第１本体２２０Ｂが互いに摺動できる程度にピンの軸方向にクリアランスを有しておく。また、同様にピンと孔２２５とも、２つの第１本体２２０Ｂが互いに摺動できる程度にクリアランスを有するように形成されている。 The circular portions 224 of the first main body 220B configured as described above are overlapped, and pins (not shown) are inserted into the holes 225 of the two overlapped circular portions 224. Note that a stopper is attached to both ends of the pin so that the circular portion 224 does not come out of the pin. At this time, the retainer has a clearance in the axial direction of the pin so that the two first main bodies 220B can slide relative to each other. Similarly, the pin and the hole 225 are formed to have a clearance so that the two first main bodies 220B can slide with respect to each other.
　第２の実施形態の変形例として、上述した構成の第１連結手段２２０－２を採用してよい。第１連結手段２２０－２を用いても、隣接する２つの上杆体２１０のなす角度を最小（略０度）にする方向及び最大（略１２０度）にする方向に移動可能とすることができる。 As a modification of the second embodiment, the first connecting means 220-2 having the above-described configuration may be employed. Even when the first connecting means 220-2 is used, it is possible to move in the direction in which the angle formed by the two adjacent upper casings 210 is minimum (approximately 0 degrees) and maximum (approximately 120 degrees). .
　また、第２の実施形態においては、上部構造２０１が回転手段２４０を備えるものとしたが、これに限定されない。ここで、本発明に係る第３の実施形態の架台構造１０２について以下図面を用いて詳細に説明する。図２９は、架台構造１０２の展開及び折り畳みの途中を示す図である。なお、本実施形態の架台構造１０２の展開状態及び折り畳み状態の形状については、上杆体の形状以外は図２５に図示して説明した形状と同じであるため、ここでの図示は省略する。また図２９は図２６と同様に、説明の便宜上、各部品の構成を簡略化している。 In the second embodiment, the upper structure 201 includes the rotating means 240, but the present invention is not limited to this. Here, the gantry structure 102 according to the third embodiment of the present invention will be described in detail with reference to the drawings. FIG. 29 is a diagram showing the middle of the deployment and folding of the gantry structure 102. The shape of the gantry structure 102 of the present embodiment in the expanded state and the folded state is the same as the shape illustrated in FIG. 25 except for the shape of the upper housing, and is not shown here. Also, in FIG. 29, as in FIG. 26, the configuration of each component is simplified for convenience of explanation.
　また、架台構造１０２は、上記架台構造１０１と同様に、上部構造２０２に設けられる支柱構造８００（後述する）や、上部構造２０２、上部構造２０２の下方で上部構造２０２を支持する中間構造３００、中間構造３００と連結し地上に設置される下部構造４００とを備えていてもよいし、上部構造２０２を直接地上に設置して、上部構造２０２のみを架台構造としてもよい。また、架台構造１０２は、上述した実施形態の図１０と同様に、宇宙空間や、水や油等の液体空間において、上部構造２０２と中間構造３００とを架台構造としてもよい。 Similarly to the gantry structure 101, the gantry structure 102 includes a support structure 800 (described later) provided in the upper structure 202, an upper structure 202, an intermediate structure 300 that supports the upper structure 202 below the upper structure 202, The lower structure 400 connected to the intermediate structure 300 and installed on the ground may be provided, or the upper structure 202 may be installed directly on the ground, and only the upper structure 202 may be a gantry structure. Further, in the gantry structure 102, the upper structure 202 and the intermediate structure 300 may be a gantry structure in outer space or a liquid space such as water or oil, as in FIG. 10 of the above-described embodiment.
　第３の実施形態においては、上杆体の第１軸心ＡＸ１と直交する断面の形状を円形状としたが、第３の実施形態の上杆体は４角形とする。第３の実施形態の上部構造２０２は、第２の実施形態の上部構造２０１と同様に、６本の上杆体２１０－２を連結して平板状の正６角形をなすように展開されており、６本の上杆体２１０－２と、正６角形の各頂点に配置され、頂点において隣接する２本の上杆体２１０－２の一端部２１１同士を連結保持する６個の第１連結手段２２０とを備える。上杆体２１０－２は長尺な柱状体であり、その長さは略等しい。なお上杆体２１０－２の長さ及び太さは、宇宙構造物、遊具、家具等の用途に応じて変更されるものであり、特に限定されない。第１の連結手段２２０は、第１及び第２の実施形態と同じものを使用することができる。 In the third embodiment, the shape of the cross section orthogonal to the first axis AX1 of the upper housing is a circular shape, but the upper housing of the third embodiment is a quadrangular shape. Similar to the upper structure 201 of the second embodiment, the upper structure 202 of the third embodiment is unfolded to connect the six upper casings 210-2 to form a flat regular hexagon. , Six upper casings 210-2 and six first connecting means 220 which are arranged at the apexes of the regular hexagon and which connect and hold one end portions 211 of the two upper casings 210-2 adjacent to each other at the apexes. With. The upper casing 210-2 is a long columnar body, and its length is substantially equal. Note that the length and thickness of the upper casing 210-2 are not particularly limited, and are changed according to the use of the space structure, playground equipment, furniture, and the like. As the first connecting means 220, the same one as in the first and second embodiments can be used.
　第３の実施形態の上杆体２１０－２は、図２９に示すように、第１軸心ＡＸ１と直交する断面の形状が４角形であり、上杆体２１０－２の第１軸心ＡＸ１方向の略中央において第１上杆体２１０Ａと第２上杆体２１０Ｂとに分割されている。第１上杆体２１０Ａと第２上杆体２１０Ｂの第１連結手段２２０側に位置する端部がそれぞれ上述した一端部２１１に相当する。なお、第３の実施形態においては、第２の実施形態の回転手段２４０は備えていないので、一端部２１１と、第１上杆体２１０Ａ又は第２上杆体２１０Ｂとは、たとえば一端部２１１側に第１軸心ＡＸ１方向の突起あるいは窪み、第１上杆体２１０Ａ又は第２上杆体２１０Ｂの本体側に第１軸心ＡＸ１方向の窪みあるいは突起を設け、窪みに突起を嵌合して固定してもよいし、公知な機構によって固定することができる。なお一端部２１１と第１上杆体２１０Ａ又は第２上杆体２１０Ｂは一体的に成形されていてもよい。 As shown in FIG. 29, the upper casing 210-2 of the third embodiment has a quadrangular cross-sectional shape perpendicular to the first axis AX1, and the upper casing 210-2 has a shape in the direction of the first axis AX1. It is divided into a first upper housing 210A and a second upper housing 210B at substantially the center. The ends of the first upper casing 210A and the second upper casing 210B located on the first connecting means 220 side correspond to the one end 211 described above. In the third embodiment, since the rotation means 240 of the second embodiment is not provided, the one end 211 and the first upper casing 210A or the second upper casing 210B are, for example, on the one end 211 side. A projection or depression in the direction of the first axis AX1, and a depression or projection in the direction of the first axis AX1 is provided on the main body side of the first upper casing 210A or the second upper casing 210B, and the projection is fitted and fixed in the depression. Alternatively, it can be fixed by a known mechanism. The one end 211 and the first upper casing 210A or the second upper casing 210B may be integrally formed.
　また、第１上杆体２１０Ａと第２上杆体２１０Ｂとは、互いに対向する端面に不図示の円筒状の突起あるいは円筒状の窪みを有し、突起を窪みに嵌め合わせることにより、第１上杆体２１０Ａと第２上杆体２１０Ｂとを互いに対して相対的に第１軸心ＡＸ１周りに回転自在にしている。なお上記突起と窪みは、第１上杆体２１０Ａと第２上杆体２１０Ｂとが摺動できる程度にクリアランスを有している。なお第１上杆体２１０Ａと第２上杆体２１０Ｂとの接続方法については、これに限られず、たとえば第１上杆体２１０Ａと第２上杆体２１０Ｂとが、互いに対向する端面に円筒状の窪みを有し、この両方の窪みに円柱状のピン（図示せず）を挿通することにより、第１上杆体２１０Ａと第２上杆体２１０Ｂとを回転自在に接続してもよい。この場合、ピンと窪みとは、第１上杆体２１０Ａと第２上杆体２１０Ｂとが摺動できる程度にクリアランスを有している。 Further, the first upper casing 210A and the second upper casing 210B have cylindrical projections or cylindrical depressions (not shown) on the end surfaces facing each other, and the projections are fitted into the depressions, whereby the first upper casing is fitted. 210A and the second upper casing 210B are relatively rotatable around the first axis AX1 relative to each other. The protrusions and the recesses have a clearance that allows the first upper casing 210A and the second upper casing 210B to slide. Note that the connection method between the first upper housing 210A and the second upper housing 210B is not limited to this. For example, the first upper housing 210A and the second upper housing 210B have cylindrical recesses on the end surfaces facing each other. Then, the first upper housing 210A and the second upper housing 210B may be rotatably connected by inserting a cylindrical pin (not shown) into both of these recesses. In this case, the pin and the recess have a clearance so that the first upper housing 210A and the second upper housing 210B can slide.
　また、第３の実施形態においては、上杆体２１０－２を第１上杆体２１０Ａと第２上杆体２１０Ｂとに分割する位置を、第１軸心ＡＸ１方向の略中央としたが、本発明はこれに限定されるものではく、第１上杆体２１０Ａと第２上杆体２１０Ｂとが互いに対して相対的に回転可能であれば、いずれの箇所において分割してもよい。また、本実施形態においては、上杆体２１０－２を第１上杆体２１０Ａと第２上杆体２１０Ｂの２つに分割したが、３つ以上の複数に分割することができる。 Further, in the third embodiment, the position at which the upper casing 210-2 is divided into the first upper casing 210A and the second upper casing 210B is set to the approximate center in the direction of the first axis AX1. However, the present invention is not limited to this, and the first upper housing 210A and the second upper housing 210B may be divided at any location as long as the first upper housing 210A and the second upper housing 210B can rotate relative to each other. In the present embodiment, the upper casing 210-2 is divided into two parts, the first upper casing 210A and the second upper casing 210B, but it can be divided into three or more.
　上部構造２０２は、展開状態（図２５の上図を参照）から、第１上杆体２１０Ａと第２上杆体２１０Ｂとを互いに対して相対的に第１軸心ＡＸ１回りに回転させながら、すなわち第１上杆体２１０Ａと第２上杆体２１０Ｂとが対向する面において、互いの断面の矩形状が一致した状態から一致しない、ずれた状態になるように回転させながら、第１連結手段２２０により、隣接する２本の上杆体２１０－２のなす角度が最小になるように、上杆体２１０－２を直交軸ＡＸ２回りに枢動すると、第１連結手段２２０が１つ置きに起こされた図２９に示す状態になる。 The upper structure 202 is rotated from the developed state (see the upper drawing of FIG. 25) while rotating the first upper casing 210A and the second upper casing 210B relative to each other around the first axis AX1, that is, On the surface where the first upper casing 210A and the second upper casing 210B face each other, the first connecting means 220 adjoins each other while rotating so that the rectangular shapes of the cross-sections do not coincide with each other and are shifted from each other. When the upper casing 210-2 is pivoted about the orthogonal axis AX2 so that the angle formed by the two upper casings 210-2 is minimized, the first connecting means 220 is raised every other one in FIG. It will be in the state shown.
　そして、上部構造２０２は、図２９の状態より、上杆体２１０－２同士をさらに近づけ、最終的には、１つ置きの３つの第１連結手段２２０をそれぞれ近接させることにより、全体として１本の柱状体に折り畳まれ、図２５の下図に示す折り畳み状態になる。 Then, the upper structure 202 brings the upper casings 210-2 closer to each other than in the state of FIG. 29, and finally, every other three first connecting means 220 are brought close to each other, so that one upper structure 202 as a whole. The columnar body is folded into a folded state shown in the lower diagram of FIG.
　なお上部構造２０２は、第１軸心ＡＸ１及び直交軸ＡＸ２の各軸回り以外に上杆体２１０－２を回転させる構造を有しない。これにより、正６角形の展開形状、１本の柱状体である折り畳み形状、及びその途中形状からなる所定形状以外の形状を有することが制限される。 Note that the upper structure 202 does not have a structure for rotating the upper casing 210-2 other than about the first axis AX1 and the orthogonal axis AX2. This restricts having a regular hexagonal unfolded shape, a folded shape that is a single columnar body, and a shape other than a predetermined shape consisting of a halfway shape.
　なお、第３の実施形態では、第１軸心ＡＸ１と直交する断面において、第１上杆体２１０Ａと第２上杆体２１０Ｂとは４角形状を有するものとしたが、第１上杆体２１０Ａと第２上杆体２１０Ｂの断面形状は、限定されるものではなく、たとえば楕円形や円形でもよい。また第１上杆体２１０Ａと第２上杆体２１０Ｂは、中実でもよく、たとえばパイプのように中空でもよい。第１上杆体２１０Ａと第２上杆体２１０Ｂの材質は、剛性を有するものであれば限定されるものではなく、たとえば金属でもよく、木材や樹脂等でもよい。 In the third embodiment, the first upper casing 210A and the second upper casing 210B have a quadrangular shape in the cross section orthogonal to the first axis AX1, but the first upper casing 210A and the first upper casing 210A The cross-sectional shape of the two upper casing 210B is not limited, and may be, for example, an ellipse or a circle. Further, the first upper casing 210A and the second upper casing 210B may be solid, for example, may be hollow like a pipe. The material of the first upper casing 210A and the second upper casing 210B is not limited as long as it has rigidity, and may be, for example, metal, wood, resin, or the like.
　上述した架台構造１０１は、構造物、建築物、人、動物、物品等を載置できる上部構造２０１と、上部構造２０１に設けられる支柱構造８００とを備えていてもよい。次に図３０～図３４を参照して、支柱構造８００について説明する。 The above-described gantry structure 101 may include an upper structure 201 on which a structure, a building, a person, an animal, an article, or the like can be placed, and a support structure 800 provided on the upper structure 201. Next, the column structure 800 will be described with reference to FIGS.
　第３の実施形態の支柱構造８００は、第３の実施形態の上部構造２０２に取り付けられるものとするが、第１及び第２の実施形態の上部構造２００，２０１に取り付けることもできる。支柱構造８００は、図３０に示すように、下端が第１連結手段２２０に回転自在に連結保持され、上端が正６角形の内方へ折り曲げ可能に立設された６本の上部杆体８１０と、上端が第１連結手段２２０に回転自在に連結保持され、下端が正６角形の内方へ折り曲げ可能に立設された６本の下部杆体８２０と、上部杆体８１０の上端と下部杆体８２０の下端との間を結ぶ１本の線材８３０を備えている。第１連結手段２２０と、上部杆体８１０の下端及び下部杆体８２０の上端とは、たとえばヒンジやピン等を用いた公知の機構を使用して連結することができる。 The column structure 800 of the third embodiment is attached to the upper structure 202 of the third embodiment, but can also be attached to the upper structures 200 and 201 of the first and second embodiments. As shown in FIG. 30, the column structure 800 includes six upper casings 810 that have lower ends rotatably connected to the first connecting means 220, and whose upper ends are erected in a regular hexagonal inward direction. The six lower housings 820, the upper ends of which are rotatably connected to the first connecting means 220 and the lower ends thereof are foldable inwardly into a regular hexagon, and the upper ends of the upper housing 810 and the lower housing 820 One wire 830 that connects the lower end is provided. The first connecting means 220 and the lower end of the upper casing 810 and the upper end of the lower casing 820 can be connected using a known mechanism using, for example, a hinge or a pin.
　上部杆体８１０及び下部杆体８２０は長尺な柱状体である。また、上部杆体８１０及び下部杆体８２０は略等しい長さを有する。上部杆体８１０及び下部杆体８２０の長さは、上杆体２１０と同様に、特に限定されるものではない。上部杆体８１０及び下部杆体８２０はそれぞれ、各々の軸心と直交する断面において、矩形状である。 The upper housing 810 and the lower housing 820 are long columnar bodies. Further, the upper casing 810 and the lower casing 820 have substantially the same length. The lengths of the upper casing 810 and the lower casing 820 are not particularly limited, like the upper casing 210. Each of the upper housing 810 and the lower housing 820 has a rectangular shape in a cross section orthogonal to each axis.
　なお上部杆体８１０及び下部杆体８２０の断面形状は、上杆体２１０と同様に、特に限定されるものではなく、楕円形状や円形状でもよい。上部杆体８１０及び下部杆体８２０は、中実でもよく、パイプのような中空でもよい。上部杆体８１０及び下部杆体８２０の材質は、剛性を有するものであれば限定されるものではなく、たとえば金属でもよく、木材や樹脂等でもよい。線材８３０は、剛性を有するものであれば限定されず、たとえばワイヤやロープ等であってもよい。 It should be noted that the cross-sectional shapes of the upper casing 810 and the lower casing 820 are not particularly limited, as with the upper casing 210, and may be elliptical or circular. The upper housing 810 and the lower housing 820 may be solid or hollow such as a pipe. The material of the upper casing 810 and the lower casing 820 is not limited as long as it has rigidity. For example, it may be metal, wood, resin, or the like. The wire 830 is not limited as long as it has rigidity, and may be, for example, a wire or a rope.
　第１連結手段２２０において、上部杆体８１０の下端は上部杆体８１０の軸心と直交する回転軸の回りに回転自在であり、下部杆体８２０の上端は下部杆体８２０の軸心と直交する回転軸の回りに回転自在である。 In the first connecting means 220, the lower end of the upper casing 810 is rotatable about a rotation axis orthogonal to the axis of the upper casing 810, and the upper end of the lower casing 820 is a rotation axis orthogonal to the axis of the lower casing 820. It can rotate freely.
　また、線材８３０には、線材８３０にテンションを付与するテンション付与手段として、テンションレバー８４０が設けられている。テンションレバー８４０は、図３０及び図３１Ａに示すように、一端８４１が上部杆体８１０の下端部の外向部に、上部構造２０２の正６角形の面に平行で、かつ正６角形の中心と上部杆体８１０の上記下端部の外向部を結ぶ線に垂直な軸に軸支され、他端８４２が線材８３０の中心部に摺動自在に係合されている。すなわち、テンションレバー８４０は、他端８４２が上部構造２０２の正６角形の外方において上下方向に移動可能に構成されている。なお本実施形態では、テンションレバー８４０の一端８４１が、上部杆体８１０の下端部の外向面に設けられているが、本発明はこれに限定されず、第１連結手段２２０の外向部に回転自在に軸支されていてもよいし、下部杆体８２０の上端部の外向部に回転自在に軸支されていてもよい。また、テンションレバー８４０は、第１連結手段２２０の近傍に設けられることが好ましく、具体的には上部杆体８１０の下端部から下部杆体８２０の上端部の範囲は、上部杆体８１０の上端から２／３の位置から第１連結手段２２０を含めて下部杆体８２０の下端から２／３までの位置とすることが好ましい。 Also, the wire rod 830 is provided with a tension lever 840 as tension applying means for applying tension to the wire rod 830. As shown in FIGS. 30 and 31A, the tension lever 840 has one end 841 at the outward portion of the lower end of the upper housing 810, parallel to the regular hexagonal surface of the upper structure 202, and the center and upper portion of the regular hexagon. The other end 842 is slidably engaged with the central portion of the wire rod 830 and is supported by an axis perpendicular to the line connecting the outward portions of the lower end portion of the casing 810. That is, the tension lever 840 is configured such that the other end 842 can move in the vertical direction outside the regular hexagon of the upper structure 202. In this embodiment, one end 841 of the tension lever 840 is provided on the outward surface of the lower end portion of the upper housing 810. However, the present invention is not limited to this, and the end lever 84 is rotatable to the outward portion of the first connecting means 220. It may be pivotally supported on the outer surface of the lower housing 820 or may be rotatably supported on the outward portion of the upper end portion of the lower housing 820. The tension lever 840 is preferably provided in the vicinity of the first connecting means 220. Specifically, the range from the lower end of the upper casing 810 to the upper end of the lower casing 820 is 2/2 from the upper end of the upper casing 810. It is preferable that the position including the first connecting means 220 is set to a position from the lower end of the lower housing 820 to 2/3 from the position 3.
　テンションレバー８４０は、図３１Ｂに示すように、他端８４２が下方向に押し込まれていない状態、すなわちテンションレバー８４０が他端８４２を上方にして斜めに位置しているときには、線材８３０にはテンションが付与されず、線材８３０は撓んだ状態となっている。このとき、上部杆体８１０と下部杆体８２０は、第１連結手段２２０に対して回転自在な状態であり、上部構造２０２の正６角形の内側へ折り畳むことができる。 As shown in FIG. 31B, the tension lever 840 has a tension applied to the wire 830 when the other end 842 is not pushed downward, that is, when the tension lever 840 is positioned obliquely with the other end 842 upward. Is not applied, and the wire 830 is bent. At this time, the upper housing 810 and the lower housing 820 are rotatable with respect to the first connecting means 220 and can be folded inside the regular hexagon of the upper structure 202.
　そしてテンションレバー８４０は、図３１Ａに示すように、テンションレバー８４０の他端８４２が下方向に押し込まれて、テンションレバー８４０が上部構造２０２の正６角形の面に略平行な位置、つまり略水平に位置したときに、他端８４２に係合された線材８３０にテンションが付与される。テンションレバー８４０によって線材８３０にテンションが付与された状態においては、線材８３０によって上部杆体８１０の上端と下部杆体８２０の下端は上部構造２０２の正６角形の外方に向けて引っ張られているので、上部杆体８１０と下部杆体８２０は、第１連結手段２２０に対して回転不可能な状態となり、位置が強固に固定される。 31A, the other end 842 of the tension lever 840 is pushed downward, and the tension lever 840 is positioned substantially parallel to the regular hexagonal surface of the upper structure 202, that is, substantially horizontal. When the wire rod 830 is positioned on the wire 830, tension is applied to the wire 830 engaged with the other end 842. In a state where the tension is applied to the wire 830 by the tension lever 840, the upper end of the upper housing 810 and the lower end of the lower housing 820 are pulled by the wire 830 toward the outside of the regular hexagon of the upper structure 202. The upper housing 810 and the lower housing 820 are in a non-rotatable state with respect to the first connecting means 220, and the positions are firmly fixed.
　上部杆体８１０は、図３１Ａに示す、線材８３０にテンションが付与された状態においては、その上端を上部構造２０２の正６角形の外側に位置させて、上方へ移動するにしたがって６本の上部杆体８１０が開いた状態となる。これにより、上部構造２０２にシート２５０を設けたときに、シート２５０上の空間を広くできる。また、上部杆体８１０の上端を覆うように屋根用シート（図３３参照）を設けたときには、シート２５０上の空間に雨が吹き込み難くなる。下部杆体８２０は、地上に向けてまっすぐ下方に延びている。 In the state where tension is applied to the wire rod 830 shown in FIG. 31A, the upper casing 810 has six upper casings as its upper end is positioned outside the regular hexagon of the upper structure 202 and moves upward. 810 is in an open state. Thereby, when the sheet 250 is provided in the upper structure 202, the space on the sheet 250 can be widened. Further, when a roof sheet (see FIG. 33) is provided so as to cover the upper end of the upper casing 810, it is difficult for rain to blow into the space on the sheet 250. The lower housing 820 extends straight downward toward the ground.
　テンションレバー８４０によって線材８３０にテンションが付与された状態、すなわち図３１Ａに示す状態においては、正６角形の各々の頂点において、上部杆体８１０、下部杆体８２０、テンションレバー及び線材８３０によって、２つのトラス構造を構成することができるので、上部杆体８１０と下部杆体８２０すなわち架台構造１０２の剛性を高められる。 In a state where the tension is applied to the wire 830 by the tension lever 840, that is, the state shown in FIG. 31A, two truss are formed by the upper housing 810, the lower housing 820, the tension lever, and the wire 830 at each vertex of the regular hexagon. Since the structure can be configured, the rigidity of the upper casing 810 and the lower casing 820, that is, the gantry structure 102 can be increased.
　また、支柱構造８００は、６本の上部杆体８１０の各々において、上部杆体８１０の上端とこの上部杆体８１０に隣接する２本の上杆体２１０－２すなわち左右の上杆体２１０－２の中間部をそれぞれ結ぶ上線材８５０Ａと、６本の下部杆体８２０の各々において、下部杆体８２０の下端とこの下部杆体８２０に隣接する２本の上杆体２１０－２すなわち左右の上杆体２１０－２の中間部をそれぞれ結ぶ下線材８５０Ｂを備えている。上線材８５０Ａと下線材８５０Ｂとが、本発明における第２の線材に相当する。 Further, in each of the six upper housings 810, the support structure 800 includes an upper end of the upper housing 810 and an intermediate portion between the two upper housings 210-2 adjacent to the upper housing 810, that is, the left and right upper housings 210-2. In each of the upper wire rod 850A and each of the six lower casings 820, the lower end of the lower casing 820 and the two upper casings 210-2 adjacent to the lower casing 820, that is, the middle portion of the left and right upper casings 210-2 are connected. Each has an underwire 850B to be tied. The upper wire 850A and the lower wire 850B correspond to the second wire in the present invention.
　上線材８５０Ａと下線材８５０Ｂは、上部杆体８１０の上端、下部杆体８２０の下端及び上杆体２１０－２の中間部に、たとえば丸環等の部材を固設して結ぶことにより固定してもよいし、適宜公知の固定方法を使用できる。また、上線材８５０Ａと下線材８５０Ｂは、図３０に示すように、テンションレバー８４０によって線材８３０にテンションが付与されている状態において、テンションが付与される長さに構成されている。つまり図３１Ｂに示す線材８３０にテンションが付与されていない状態すなわち上部杆体８１０や下部杆体８２０が完全に立ち上がっていない状態においては、上線材８５０Ａと下線材８５０Ｂは、テンションが付与されておらず撓んだ状態になっている。上線材８５０Ａと下線材８５０Ｂは、剛性を有するものであれば限定されず、たとえばワイヤやロープ等であってもよい。 The upper wire member 850A and the lower wire member 850B may be fixed by fixing a member such as a round ring to the upper end of the upper case 810, the lower end of the lower case 820, and the middle part of the upper case 210-2. And a well-known fixing method can be used suitably. Further, as shown in FIG. 30, the upper wire 850A and the lower wire 850B are configured to have a length to which tension is applied in a state where tension is applied to the wire 830 by the tension lever 840. That is, in a state where no tension is applied to the wire 830 shown in FIG. 31B, that is, in a state where the upper housing 810 and the lower housing 820 are not fully raised, the upper wire 850A and the lower wire 850B are not applied with tension and are bent. It is in a state of being stuck. The upper wire 850A and the lower wire 850B are not limited as long as they have rigidity, and may be, for example, a wire or a rope.
　支柱構造８００において、上線材８５０Ａと下線材８５０Ｂとを設けることにより、テンションレバー８４０によって線材８３０にテンションが付与された状態、すなわち図３１Ａに示す状態においては、正６角形の各々の頂点において、上部杆体８１０、下部杆体８２０、テンションレバー及び線材８３０による２つのトラス構造に加えてさらに４つのトラス構造を構成することができるので、上部杆体８１０と下部杆体８２０すなわち架台構造１０２の剛性をさらに高められる。 In the strut structure 800, by providing the upper wire 850A and the lower wire 850B, in the state where tension is applied to the wire 830 by the tension lever 840, that is, in the state shown in FIG. 31A, at each vertex of the regular hexagon, In addition to the two truss structures formed by the upper casing 810, the lower casing 820, the tension lever and the wire rod 830, four more truss structures can be formed, so that the rigidity of the upper casing 810 and the lower casing 820, that is, the gantry structure 102 is further increased. It is done.
　なお第３の実施形態において、上線材８５０Ａ及び下線材８５０Ｂは上杆体２１０－２の中間部に連結したが、特に限定されない。上線材８５０Ａが連結されている上部杆体８１０が連結された第１連結手段２２０から隣の連結手段までの間の１／３の位置から隣の連結手段に至るまでの間であればいずれの箇所に連結してもよい。特に、上線材８５０Ａは、上部構造２０２にシート２５０が設けられているとき等に、上線材８５０Ａが人の出入りの邪魔になり難いので、出入り口を大きくとるために上記１／３の位置に連結することが好ましい。 In the third embodiment, the upper wire member 850A and the lower wire member 850B are connected to the middle portion of the upper housing 210-2, but are not particularly limited. Any location from the 1/3 position between the first connecting means 220 to which the upper housing 810 to which the upper wire 850A is connected to the adjacent connecting means to the adjacent connecting means is reached. You may connect to. In particular, the upper wire 850A is connected to the above-mentioned position 1/3 in order to make the doorway larger because the upper wire 850A is unlikely to obstruct people when the upper structure 202 is provided with a sheet 250. It is preferable to do.
　上記のように構成された支柱構造８００は、テンションレバー８４０によって線材８３０にテンションを付与しない状態、すなわち図３１Ｂに示す状態において、上部杆体８１０及び下部杆体８２０をそれぞれ上部構造８２０の正６角形の内側へ折り曲げた後で、上部構造２０２を折り畳むことにより、図２９に示す第１連結手段２２０に追従して、この第１連結手段２２０に連結された上部杆体８１０及び下部杆体８２０がこの第１連結手段２２０を支点にして回動することにより、上部杆体８１０及び下部杆体８２０が上杆体２１０－２全体に近接していき、上線材８５０Ａ及び下線材８５０Ｂも、上部杆体８１０及び下部杆体８２０の回動に追従して撓むので、最終的には上部構造２０２と一緒に１本の柱状態に折り畳みできる。 The strut structure 800 configured as described above is a regular hexagonal shape of the upper structure 820 in the state in which no tension is applied to the wire 830 by the tension lever 840, that is, in the state shown in FIG. 31B. After folding inward, the upper structure 202 is folded to follow the first connecting means 220 shown in FIG. 29 so that the upper casing 810 and the lower casing 820 connected to the first connecting means 220 are connected to the first connecting means 220. By rotating with the connecting means 220 as a fulcrum, the upper housing 810 and the lower housing 820 are brought close to the entire upper housing 210-2, and the upper wire 850A and the lower wire 850B are also connected to the upper housing 810 and the lower housing 820. Since it bends following the rotation, it can finally be folded together with the upper structure 202 into a single column.
　本発明においては、上記架台構造１０２にさらに上述した中間構造３００を設けることができる。ここで本発明に係る第４の実施形態の架台構造１０３について図面を参照して説明する。図３２に、中間構造３００を備えた架台構造１０３を右斜め上方から見た斜視図、図３３に中間構造３００、シート２５０及び屋根用シート８７０を備えた架台構造１０３を右斜め上方から見た斜視図をそれぞれ示す。なお本実施形態において上部構造２０２はシート２５０が設けられたものとする。 In the present invention, the above-described intermediate structure 300 can be further provided on the gantry structure 102. Here, a gantry structure 103 according to a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 32 is a perspective view of the gantry structure 103 including the intermediate structure 300 as viewed from the upper right, and FIG. 33 illustrates the gantry structure 103 including the intermediate structure 300, the seat 250, and the roof sheet 870 as viewed from the upper right. A perspective view is shown respectively. In the present embodiment, the upper structure 202 is provided with a sheet 250.
　架台構造１０３は、図３２、図３３に示すように、上部構造２０２、支柱構造８００、中間構造３００、シート２５０、ポール８６０及び屋根用シート８７０とを備えている。架台構造１０３は、図３２に示すように、第１連結手段２２０に一端部３１１が回転自在に連結保持される６本の中間杆体３１０と、中間杆体３１０の他端部３１２を集束させて回転自在に連結保持する第３連結手段３２０とを備えてなる中間構造３００を備えている。なお中間構造３００については上述した実施形態の架台構造１００に設けられるものと同様の構造であるため、ここでの詳細な説明は省略する。 The gantry structure 103 includes an upper structure 202, a support structure 800, an intermediate structure 300, a seat 250, a pole 860, and a roof sheet 870, as shown in FIGS. 32 and 33. As shown in FIG. 32, the gantry structure 103 rotates by focusing the six intermediate housings 310 whose one end portions 311 are rotatably connected to the first connecting means 220 and the other end portions 312 of the intermediate housing 310. An intermediate structure 300 including third connecting means 320 that is freely connected and held is provided. Since the intermediate structure 300 is the same structure as that provided in the gantry structure 100 of the above-described embodiment, detailed description thereof is omitted here.
　中間構造３００の第３連結手段３２０は円形状であり、円形の上面にポール８６０が取外し可能に取り付けられる。ポール８６０は、図３２に示すように、上部杆体８１０の長さよりも長く構成されており、図３３に示すように、ポール８６０の上端には、屋根用シート８７０が被される。ポール８６０は、シート２５０の略中央に設けられた不図示の孔を貫通して上方に延びており、この孔はポール８６０が倒れるのを防止している。なお孔とポール８６０との間は、ポール８６０が孔から抜け出すことが可能な程度のクリアランスを有している。 The third connecting means 320 of the intermediate structure 300 has a circular shape, and the pole 860 is detachably attached to the circular upper surface. The pole 860 is configured to be longer than the length of the upper casing 810 as shown in FIG. 32, and the roof sheet 870 is covered on the upper end of the pole 860 as shown in FIG. The pole 860 extends upward through a hole (not shown) provided substantially at the center of the seat 250, and this hole prevents the pole 860 from falling down. Note that there is a clearance between the hole and the pole 860 so that the pole 860 can come out of the hole.
　屋根用シート８７０は、上部杆体８１０の上端で形成される正６角形よりも大きい正６角形で構成されており、図３３に示すように、屋根用シート８７０の中央部がポール８６０の上端に被さり、屋根用シート８７０の縁部は上部杆体８１０の上端に覆い被さっている。なお屋根用シート８７０の素材は、可撓性を有するものであれば限定されるものではく、たとえば布地や、ナイロンやビニール等の樹脂でもよいが、防水加工が施されていることが望ましい。また屋根用シート８７０は、ポール８６０や上部杆体８１０の上端に取外し可能に、たとえばロープ等を使用して固定されていてもよいし、単に被せておいてもよいし、用途によって適宜変更することができる。 The roof sheet 870 is formed in a regular hexagon that is larger than the regular hexagon formed at the upper end of the upper casing 810, and the center of the roof sheet 870 is located at the upper end of the pole 860 as shown in FIG. 33. The edge of the roof sheet 870 covers the upper end of the upper casing 810. The material of the roof sheet 870 is not limited as long as it has flexibility. For example, it may be a cloth or a resin such as nylon or vinyl, but is preferably waterproofed. Further, the roof sheet 870 may be fixed to the upper ends of the pole 860 and the upper housing 810, for example, may be fixed using a rope or the like, or may be simply covered, or may be appropriately changed depending on the application. Can do.
　屋根用シート８７０は可撓性を有しているので、取り付けたままの状態で架台構造１０２を折り畳んだり展開したりすることができる。ポール８６０は、架台構造１０２を折り畳むときには、先に取り外される。また架台構造１０２を折り畳んだ状態から展開するときには、展開した状態になった後に、ポール８６０を取り付ける。なおポール８６０に、各種照明器具やテーブル等を取り付けて使用することができる。また、図示は省略するが、架台構造１０３の上部構造２０２の上方の側面、すなわち上部杆体８１０が構成する周面に、側面シートを設けることができる。側面シートは、上部杆体８１０に取外し可能に懸架されていることが好ましい。側面シートの素材は、特に限定されるものではなく、たとえば布地や、ナイロンやビニール等の樹脂でもよい。また側面シートは特に可撓性を有するものに限定されるものではなく、板状のもので構成してもよい。架台構造１０３を屋外で使用する場合には、防水加工が施されていることが望ましい。側面シートも取り付けたまま架台構造２を折り畳んだり展開したりすることが出来る。 Since the roof sheet 870 is flexible, the gantry structure 102 can be folded and unfolded while attached. The pole 860 is removed first when the gantry structure 102 is folded. Further, when the gantry structure 102 is expanded from the folded state, the pole 860 is attached after the expanded state. Note that various kinds of lighting fixtures, tables, and the like can be attached to the pole 860 for use. Although illustration is omitted, a side sheet can be provided on the side surface above the upper structure 202 of the gantry structure 103, that is, on the peripheral surface formed by the upper housing 810. The side sheet is preferably detachably suspended from the upper housing 810. The material of the side sheet is not particularly limited, and may be, for example, a cloth or a resin such as nylon or vinyl. Further, the side sheet is not particularly limited to one having flexibility, and may be constituted by a plate-like one. When the gantry structure 103 is used outdoors, it is desirable that the waterproof structure is applied. The gantry structure 2 can be folded or unfolded with the side sheets attached.
　なお架台構造１０３は、６本の下杆体４１０と、下杆体４１０と第３連結手段３２０とを結合する線材４２０とを備えることができる。線材４２０は、上述した下部構造４００で使用する線材４２０と同じ構成のものを使用することができ、剛性を有するものであれば限定されず、たとえばワイヤやロープ等であってもよい。なお折り畳み時において、下部杆体８２０は中間杆体３１０に近接するように折り畳まれ、線材４２０も追従して撓む。 Note that the gantry structure 103 can include six lower casings 410 and a wire rod 420 that connects the lower casings 410 and the third connecting means 320. The wire 420 can be the same as the wire 420 used in the lower structure 400 described above, and is not limited as long as it has rigidity, and may be a wire, a rope, or the like. At the time of folding, the lower casing 820 is folded so as to be close to the intermediate casing 310, and the wire 420 is also bent following the bending.
　本発明において、上部杆体８１０及び下部杆体８２０の本数は、特に限定されるものではないが、架台構造１０２、１０３を安定させるため、３本以上であることが望ましい。上部杆体８１０は、天上に向けて斜め上方に延び、且つ等間隔に配置されていることが望ましい。また、下部杆体８２０は伸縮自在に調整可能とすることができる。ここで図３４に、伸縮調整機構を有する下部杆体９００の斜視図を示す。図３４の左図は縮んだ状態、右図は伸びた状態をそれぞれ示す。 In the present invention, the number of the upper housing 810 and the lower housing 820 is not particularly limited, but is preferably 3 or more in order to stabilize the gantry structures 102 and 103. It is desirable that the upper casing 810 extends obliquely upward toward the top and is arranged at equal intervals. In addition, the lower housing 820 can be adjusted to be extendable. Here, FIG. 34 shows a perspective view of a lower casing 900 having an expansion / contraction adjustment mechanism. The left figure of FIG. 34 shows the contracted state, and the right figure shows the extended state.
　下部杆体９００は、上端が第１連結手段２２０に連結され、下端に矩形状の固定板８２１を有する下部杆体本体８２０－２と、上下端に矩形状の可動板９１０を有し、この２枚の可動板９１０に固設される２本の可動棒９２０を有する伸縮可動部９３０とを備えている。下部杆体本体８２０－２の固定板８２１には、後述するロープ９４０が挿通する挿通孔８２１ａが設けられており、下部杆体本体８２０－２の上側には、ロープ９４０を係止するための係止部８２２が設けられている。係止部８２２は、ロープ９４０が挿通する挿通路８２３を有し、この挿通路８２３の内面には複数の凹凸が設けられており、この凹凸による摩擦力によってロープ９４０を係止している。なお係止部８２２の構造については、ロープ９４０を確実に係止できる構造であれば特に限定されるものではなく、公知の構造を使用することができる。 The lower casing 900 has a lower casing body 820-2 having an upper end connected to the first connecting means 220 and having a rectangular fixed plate 821 at the lower end, and a rectangular movable plate 910 at the upper and lower ends. And a telescopic movable portion 930 having two movable rods 920 fixed to the movable plate 910. The fixing plate 821 of the lower casing main body 820-2 is provided with an insertion hole 821a through which a rope 940, which will be described later, is inserted, and a locking for locking the rope 940 is provided above the lower casing main body 820-2. A portion 822 is provided. The locking portion 822 has an insertion path 823 through which the rope 940 is inserted, and a plurality of irregularities are provided on the inner surface of the insertion path 823, and the rope 940 is locked by a frictional force caused by the irregularities. The structure of the locking portion 822 is not particularly limited as long as it can reliably lock the rope 940, and a known structure can be used.
　ロープ９４０は、固定板８２１の挿通孔８２１ａを挿通し、その先端は２つの可動板９１０のうち上方に位置する可動板９１０に固定されている。固定方法としては、たとえば可動板９１０に丸環等を固設して、ロープ９４０を結んでもよいし、公知の方法を使用できる。 The rope 940 is inserted through the insertion hole 821a of the fixed plate 821, and the tip thereof is fixed to the movable plate 910 located above the two movable plates 910. As a fixing method, for example, a round ring or the like may be fixed to the movable plate 910 and the rope 940 may be tied, or a known method can be used.
　上記のように構成された下部杆体９００は、図３４の左図に示す縮んだ状態で、ロープ９４０を矢印Ｐ１の方向に引っ張ることにより、ロープ９４０の先端に固定された上側の可動板９１０が矢印Ｐ２の方向すなわち下方向に引っ張られて移動することにより、伸縮可動部９３０全体が、図３４の右図に示すように下方向へ移動し、下部杆体９００が伸びた状態となる。この状態でロープ９４０を係止部８２２で固定することにより、下部杆体９００は伸びた状態に保持される。 The lower casing 900 configured as described above has the upper movable plate 910 fixed to the tip of the rope 940 by pulling the rope 940 in the direction of arrow P1 in the contracted state shown in the left diagram of FIG. By moving by pulling and moving in the direction of the arrow P2, that is, in the downward direction, the entire telescopic movable portion 930 moves downward as shown in the right diagram of FIG. 34, and the lower casing 900 is extended. In this state, by fixing the rope 940 with the locking portion 822, the lower housing 900 is held in an extended state.
　また下部杆体９００を図３４の右図に示す伸びた状態から、縮んだ状態にするには、係止部８２２によるロープ９４０の係止を解除し、たとえば人の手によって下方の可動板９１０を上方へ押し込むことにより、図３４の左図に示す縮んだ状態になる。そして、縮んだ状態でロープ９４０を係止部８２２で固定することにより、下部杆体９００は縮んだ状態に保持される。このように下部杆体９００が伸縮機能を備えることにより、起伏が激しい不整地であっても、架台構造１０２を安定して設置できる。なお下部杆体の伸縮機能については、これに限定されず、公知の機構を使用することができる。 In order to change the lower casing 900 from the extended state shown in the right diagram of FIG. 34 to the contracted state, the locking of the rope 940 by the locking portion 822 is released, and the lower movable plate 910 is moved by a human hand, for example. By pushing upward, the compressed state shown in the left diagram of FIG. 34 is obtained. And by fixing the rope 940 with the latching | locking part 822 in the contracted state, the lower housing 900 is hold | maintained in the contracted state. Since the lower casing 900 has an expansion / contraction function in this way, the gantry structure 102 can be stably installed even on rough terrain. In addition, about the expansion-contraction function of a lower housing, it is not limited to this, A well-known mechanism can be used.
　次に本発明に係る第５の実施形態の架台構造１０４について以下図面を用いて詳細に説明する。図３５は、４角形の上部構造２０４からなる架台構造１０４の展開及び折り畳みを示す図である。なお上述した実施形態の架台構造１０１、１０２、１０３と同様の構成については同じ符号を使用して説明は省略する。 Next, the gantry structure 104 according to the fifth embodiment of the present invention will be described in detail with reference to the drawings. FIG. 35 is a diagram showing the unfolding and folding of the gantry structure 104 including the quadrangular upper structure 204. In addition, about the structure similar to the gantry structure 101,102,103 of embodiment mentioned above, description is abbreviate | omitted using the same code | symbol.
　本実施形態の架台構造１０４は、上記架台構造１０１、１０２、１０３と同様に、上部構造２０４に設けられる支柱構造８００や、上部構造２０４、上部構造２０４の下方で上部構造２０４を支持する中間構造３００、中間構造３００と連結し地上に設置される下部構造４００とを備えていてもよいし、上部構造２０４を直接地上に設置して、上部構造２０４のみを架台構造としてもよい。また、架台構造１０４は、上述した実施形態の図１０と同様に、宇宙空間や、水や油等の液体空間において、上部構造２０４と中間構造３００とを架台構造としてもよい。 The gantry structure 104 according to the present embodiment is similar to the gantry structures 101, 102, and 103, and includes a support structure 800 provided in the upper structure 204, and an intermediate structure that supports the upper structure 204 below the upper structure 204 and the upper structure 204. 300 and the lower structure 400 connected to the intermediate structure 300 and installed on the ground, or the upper structure 204 may be installed directly on the ground, and only the upper structure 204 may be a gantry structure. In addition, in the gantry structure 104, the upper structure 204 and the intermediate structure 300 may be a gantry structure in outer space or a liquid space such as water or oil, as in FIG. 10 of the above-described embodiment.
　架台構造１０４の上部構造２０４は、４本の上杆体２１０－２を連結して平板状の正方形をなすように展開されており、４本の上杆体２１０－２と、正方形の各頂点に配置され、頂点において隣接する２本の上杆体２１０－２の一端部２１１同士を連結保持する４個の第１連結手段２２０を備える。 The upper structure 204 of the gantry structure 104 is expanded so as to form a flat square by connecting the four upper casings 210-2, and is arranged at the apexes of the four upper casings 210-2. In addition, four first connecting means 220 for connecting and holding one end portions 211 of two upper casings 210-2 adjacent to each other at the apex are provided.
　上部構造２０４は、図３５の上図に示す展開状態から、第１上杆体２１０Ａと第２上杆体２１０Ｂとを互いに対して相対的に第１軸心ＡＸ１回りに回転させながら、すなわち第１上杆体２１０Ａと第２上杆体２１０Ｂとが対向する面において、互いの断面の矩形状が一致した状態から一致しない、ずれた状態になるように回転させながら、隣接する２本の上杆体２１０－２のなす角度が最小になるように、上杆体２１０－２を直交軸ＡＸ２回りに枢動すると、第１連結手段２２０が１つ置きに起こされた図３５の中図に示す状態になる。 The upper structure 204 is rotated from the unfolded state shown in the upper diagram of FIG. 35 while rotating the first upper casing 210A and the second upper casing 210B relative to each other around the first axis AX1, that is, the first upper Two adjacent upper casings 210-2 are rotated while rotating so that the rectangular shapes of the cross-sections do not coincide with each other on the surface where the casing 210A and the second upper casing 210B face each other. When the upper casing 210-2 is pivoted about the orthogonal axis AX2 so that the angle between the first connecting means 220 is raised every other one, the state shown in the middle figure of FIG. 35 is obtained.
　そして、上部構造２０４は、図３５の中図の状態より、上杆体２１０－２同士をさらに近づけ、最終的には、向かい合う２つの第１連結手段２２０をそれぞれ近接させることにより、全体として１本の柱状体に折り畳まれ、図３５の下図に示す折り畳み状態になる。 Then, the upper structure 204 has one upper member 210-2 as a whole by bringing the upper casings 210-2 closer to each other and finally bringing the two first coupling means 220 facing each other closer to each other than the state of the middle diagram of FIG. Is folded into a columnar body, and the folded state shown in the lower part of FIG. 35 is obtained.
　なお、上部構造２０４は、第１軸心ＡＸ１及び直交軸ＡＸ２の各軸回り以外に上杆体２１０－２を回転させる構造を有しない。これにより、正方形の展開形状、１本の柱状体である折り畳み形状、及びその途中形状からなる所定形状以外の形状を有することが制限される。 Note that the upper structure 204 does not have a structure for rotating the upper casing 210-2 other than about the first axis AX1 and the orthogonal axis AX2. Accordingly, it is limited to have a shape other than a predetermined shape including a square developed shape, a folded shape which is a single columnar body, and a shape in the middle of the folded shape.
　なお本発明の架台構造においては、上杆体２１０－２が等長であればよく、上部構造の展開形状は正方形に限定されるものではない。したがって、上部構造の展開形状は、たとえばひし形であってもよいし、２Ｎ角形（Ｎは２以上の整数）であればよい。 In the gantry structure of the present invention, it is sufficient that the upper casing 210-2 has an equal length, and the developed shape of the upper structure is not limited to a square. Accordingly, the developed shape of the superstructure may be, for example, a rhombus or a 2N square (N is an integer of 2 or more).
　そして、展開形状が２Ｎ角形（Ｎは２以上の整数）である場合、本発明の上部構造は、２Ｎ本の上杆体、２Ｎ個の第１連結手段２２０、２Ｎ個の回転手段２４０を備えればよい。なお上杆体が第１上杆体２１０Ａと第２上杆体２１０Ｂとに分割された上杆体２１０－２を使用する場合には、上記回転手段２４０は必要ない。 When the developed shape is a 2N square (N is an integer greater than or equal to 2), the superstructure of the present invention includes 2N upper casings, 2N first connecting means 220, and 2N rotating means 240. That's fine. If the upper casing 210-2 is divided into the first upper casing 210A and the second upper casing 210B, the rotating means 240 is not necessary.
　また、上部構造の展開形状が２Ｎ角形（Ｎは２以上の整数）である場合、シートの形状も２Ｎ角形（Ｎは２以上の整数）とすればよい。上部構造は、高重量の部材等を載置させる場合、シート２５０の代わりに、金属や木材等の高い剛性を有する平板を支持板としてもよい。 Further, when the developed shape of the superstructure is a 2N square (N is an integer of 2 or more), the shape of the sheet may be a 2N square (N is an integer of 2 or more). In the superstructure, when a heavy member or the like is placed, a flat plate having high rigidity such as metal or wood may be used as the support plate instead of the sheet 250.
　次に本発明の架台構造を２つ備えて構成された構造体１０００について、以下図面を用いて詳細に説明する。図３６は、構造体１０００の斜視図である。なお本実施形態の構造体１０００は、上述した第２の架台構造１０１のシート２５０を備えた態様のものを使用したが、本発明はこれに限られるものではなく、架台構造１００、第３の架台構造１０２、第４の架台構造１０３、第５の架台構造１０４を用いてもよいし、シート２５０を備えていない架台構造を使用することもできる。 Next, a structure 1000 configured with two gantry structures of the present invention will be described in detail with reference to the drawings. FIG. 36 is a perspective view of the structure 1000. Note that the structure 1000 of the present embodiment is the one provided with the sheet 250 of the second gantry structure 101 described above, but the present invention is not limited to this, and the gantry structure 100, the third structure The gantry structure 102, the fourth gantry structure 103, and the fifth gantry structure 104 may be used, or a gantry structure that does not include the seat 250 may be used.
　構造体１０００は、図３６に示すように、上部構造２０１からなる架台構造１０１を、正６角形を含む平面に垂直な方向に間隔をおいて２つ、すなわち上下に２つ備えている。また、上下の架台構造１０１の正６角形の各頂点に取外し可能に連結固定する支柱１００１を６本備えている。本実施形態においては、支柱１００１は第１連結手段２２０に連結固定されている。 36. As shown in FIG. 36, the structure body 1000 includes two gantry structures 101 made of the upper structure 201 at intervals in a direction perpendicular to a plane including a regular hexagon, that is, two above and below. In addition, six support columns 1001 that are detachably connected and fixed to the respective apexes of the regular hexagon of the upper and lower frame structure 101 are provided. In this embodiment, the support column 1001 is connected and fixed to the first connecting means 220.
　支柱１００１は、その両端をそれぞれ上下に位置する架台構造１０１の第１連結手段２２０に取外し可能に連結固定されており、図３６に示す組み立てた状態では、支柱１００１によって２つの架台構造１０１の正６角形が強固に固定されているので、支柱１００１により架台構造１０１を安定且つ高い剛性で支持することができる。また支柱１００１の両端を２つの架台構造１０１の第１連結手段２２０からそれぞれ取外した後で、２つの架台構造１０１を上述したようにして１本の柱状に折り畳むことにより、コンパクトに収納した状態での持ち運びが可能となる。 The support column 1001 is detachably connected and fixed to the first connection means 220 of the gantry structure 101 whose both ends are vertically positioned. In the assembled state shown in FIG. Since the hexagon is firmly fixed, the gantry structure 101 can be supported stably and with high rigidity by the support column 1001. In addition, after removing both ends of the column 1001 from the first connecting means 220 of the two frame structures 101, the two frame structures 101 are folded into one column as described above, so that the column 100 can be stored compactly. Can be carried around.
