Variable shape three-dimensional structure using extendable arm
A variable shape three-dimensional structure includes: an upper frame; a lower frame; and a longitudinal coupling member that couples the upper and lower frames. Each of the frames includes cross units and an end coupling portion. Each cross unit is formed by two rigid members crossing each other and pivotally coupled together. The end coupling portion pivotally couples the ends of the rigid members of the cross units. The longitudinal coupling member includes a bent unit comprising a first and second bent rigid members, and a bent portion coupling shaft. The first and second bent rigid members are bent in a V-shape. The bent portion coupling shaft pivotally couples the bent portions of the first and second bent rigid members. The upper end of the bent unit is coupled to the upper frame and the lower end of the bent unit is coupled to the lower frame.
