Claim 12:
13. A variable shape structure comprising:
a first bend member having a first central coupling point, a first one-end coupling point, and a first other-end coupling point that are arranged so as to form a V shape with a fixed bend angle;
a second bend member having a second central coupling point, a second one-end coupling point, and a second other-end coupling point that are arranged so as to form a V shape with a fixed bend angle, the second central coupling point being pivotally coupled to the first central coupling point of the first bend member;
a third bend member having a third central coupling point, a third one-end coupling point, and a third other-end coupling point that are arranged so as to form a V shape with a fixed bend angle, at least one of the third one-end coupling point and the third other-end coupling point being coupled to one of the first one-end coupling point and the first other-end coupling point of the first bend member, wherein
the structure forms a panel by coupling together a plurality of extendable arms that are adjacent in an X direction and a Y direction, wherein
the second bend member is adjacent to the first bend member in the Y direction, wherein
the third bend member is adjacent to the first bend member in the X direction, the third one-end coupling point being pivotally coupled to the first one-end coupling point of the first bend member,
the structure further comprising:
a fourth bend member having a fourth central coupling point, a fourth one-end coupling point, and a fourth other-end coupling point that are arranged so as to form a V shape with a fixed bend angle, the fourth bend member being adjacent to the second bend member in the X direction, the fourth one-end coupling point being pivotally coupled to the second one-end coupling point of the second bend member, the fourth central coupling point being pivotally coupled to the third central coupling point of the third bend member, wherein
the first, second, third and fourth bend members each comprise linearly contiguous cross units to make up an extendable arm of the plurality of extendable arms, and wherein
each of the cross units comprises a first linear member, a second linear member crossing the first linear member, and a pivot shaft via which the first linear member and the second linear member are pivotally coupled together at an intersection.
