VARIABLE SHAPE FRAME AND VARIABLE SHAPE THREE-DIMENSIONAL STRUCTURE
A variable shape frame having a polygonal shape includes: extendable arms (A, B, C, D) forming each side of a polygonal frame; and corner members (10) located at at least two of the corners of the polygon. Each of the extendable arms includes a plurality of cross units (1) each formed by two rigid members (1a, lb) crossing each other in an X-shape and pivotally coupled by a middle coupling shaft (2), and an end coupling portion pivotally coupling ends of adjacent ones of the cross units. The end coupling portion includes inner end coupling shafts (3) located on the inner side of the polygonal frame and outer end coupling shafts (4) located on the outer side of the polygonal frame. Adjacent two of the extendable arms are pivotally coupled by a common one of the inner end coupling shafts (3) at every corner of the polygon. The corner member (10) includes a first guide portion (13) linearly guiding two or more of the inner end coupling shafts (3) of the first extendable arm (A) in the longitudinal direction of the side, and a second guide portion (14) linearly guiding two or more of the inner end coupling shafts (3) of the second extendable arm (B) in the longitudinal direction of the side.
