Document Type and Number:
Japanese Patent JP6391125
Kind Code:
B2
Abstract:
A variable shape frame includes: a plurality of extendable arms (A,B,C,D) arranged to form a frame; and a coupling mechanism (30) that couples ends of adjoining ones of the extendable arms so that the adjoining extendable arms can move together. Each extendable arm includes cross units (20) each formed by two rigid members (21,22) crossing in an X-shape and pivotally coupled by a middle coupling shaft (23), and an end coupling portion pivotally coupling ends of adjoining ones of the cross units. The end coupling portion includes inner end coupling shafts (25) and outer end coupling shafts (24). Each rigid member has a curved shape. The coupling mechanism (30) includes first bent members (26) each pivotally coupling the inner end coupling shaft of one of the extendable arms and the outer end coupling shaft of the other extendable arm, second bent members (27) each pivotally coupling the outer end coupling shaft of the one of the extendable arms and the inner end coupling shaft of the other extendable arm, and bent portion coupling shafts (28) each pivotally coupling the first and second bent members.
