Abstract

This presentation proposes a new kind of a scissors technique, which is a framework structure comprising three or more primary constituent units, each including two rigid diagonal members constituting the diagonals of a quadrangular lateral face of a solid and coupled together for relative rotation about a first rotation axis passing through the intersection of the diagonals. The primary constituent units are coupled to one another via second and third rotation axes into a ring-like form. A more complicated framework structure can be obtained by using a plurality of these framework structures as secondary constituent units which are coupled to one another with a coupler or a primary constituent unit (scissors) used in common between adjacent ones of the secondary constituent units. Using complete pin joints composed by three axes in between scissors
