    • 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.
    • 一种可变形状的框架包括:多个可延伸的臂(A,B,C,D),被布置成形成框架; 和联接机构(30),联接机构(30)联接相邻的可延伸臂的端部,使得相邻的可延伸臂能够一起移动。 每个可伸展臂包括交叉单元(20)和端部联接部分,每个交叉单元(20)由两个X形交叉的刚性构件(21,22)形成并且通​​过中间联接轴(23)可枢转地联接,所述端部联接部分可枢转地联接相邻 交叉单位。 端部联接部分包括内端联接轴(25)和外端联接轴(24)。 每个刚性构件具有弯曲的形状。 连结机构30包括:第一弯曲部件26,其分别枢轴连结一方的伸缩臂的内端连结轴和另一方的伸缩臂的外端连结轴;第二弯曲部件27, 所述一个可伸缩臂的一端连接轴和另一可伸缩臂的内端连接轴,以及各自枢转地连接第一和第二弯曲部件的弯曲部连接轴(28)。
