Abstract
Self-supporting structures and panels of diverse shapes are disclosed in which basic assemblies of crossed rod elements are employed to achieve the desired shape. Further, the crossing points of crossed rod elements in the structure involved may include limited sliding connections which effect transfer of collapsing force to other crossing points which are pivotally joined. An improved hub structure for pivotally joining ends of the rod elements at the outer and inner apical points is also disclosed.
