Variable shape frame using extendable arm
A variable shape frame includes: a plurality of extendable arms to form a frame; and a coupling mechanism that couples ends of adjoining extendable arms. Each extendable arm includes cross units having by two rigid members crossing in an X-shape and pivotally coupled by a middle coupling shaft, and an end coupling portion pivotally coupling ends of adjoining cross units. The end coupling portion includes inner and outer end coupling shafts. Each rigid member has a curved shape. The coupling mechanism includes first bent members each pivotally coupling the inner end coupling shaft of one extendable arm and the outer end coupling shaft of the other extendable arm, second bent members each pivotally coupling the outer end coupling shaft of the one extendable arm and the inner end coupling shaft of the other extendable arm, and bent portion coupling shafts each pivotally coupling the first and second bent members.
