EXTENDABLE ARM, VARIABLE SHAPE FRAME, AND VARIABLE SHAPE THREE-DIMENSIONAL STRUCTURE
An extendable arm is comprised of a plurality of cross units arranged in one direction with adjacent ones of the cross units being pivotally coupled at their ends via end coupling shafts. Each of the cross units is comprised of first and second rigid members crossing each other in an X shape and pivotally coupled at their intersection via a middle coupling shaft. The extendable arm includes an engaging protrusion and an engaging recess which move toward each other as the extendable arm extends and fit together when the extendable arm extends to a predetermined length.
