SHAPE VARIABLE FRAME BODY AND SHAPE VARIABLE SOLID STRUCTURE
PROBLEM TO BE SOLVED: To provide a shape variable frame body and a shape variable solid structure of which shape can be changed in response to a telescopic action of telescopic arms.SOLUTION: A shape variable frame comprises telescopic arms A, B, C and D constituting each side of polygonal frame and corner members 10 located in at least two corners of the polygonal frame. Each of the telescopic arms includes several cross units 1 having two rigid members crossed in an X-shape form that are pivotally connected through central connecting shafts 2 and the end part connecting portions rotatably connecting the end portions of the adjoining cross units 1. The end part connecting portions include inside end connecting shafts 3 located inside the frame and outside end connecting shafts 4 located outside. The corner members 10 have the first guiding portions 13 for use in guiding the several inside end connecting shafts 3 of the first telescopic arms A in a straight-line manner along a length direction of the side, and the second guiding portions 14 for use in guiding several inside end connecting shafts 3 of the second telescopic arms B in a straight-line manner along a side length direction.SELECTED DRAWING: Figure 1
【課題】伸縮アームの伸縮動作に応じて形状を変えることのできる形状可変枠体および形状可変立体構造物を提供する。【解決手段】形状可変枠体は、多角形の枠体の各辺を構成する伸縮アームＡ，Ｂ，Ｃ，Ｄと、多角形の少なくとも２つのコーナー部に位置するコーナー部材１０とを備え、各伸縮アームは、Ｘ字状に交差させた２個の剛性部材を中央連結軸２を介して回動可能に連結した複数のクロスユニット１と、隣接するクロスユニット１の端部同士を回動可能に連結する端部連結部とを含み、端部連結部は、枠体の内側に位置する内側端連結軸３と、外側に位置する外側端連結軸４とを含み、コーナー部材１０は、第１伸縮アームＡの複数の内側端連結軸３を辺の長さ方向に沿って直線的に案内する第１案内部１３と、第２伸縮アームＢの複数の内側端連結軸３を辺の長さ方向に沿って直線的に案内する第２案内部１４とを有する。【選択図】図１
