We advance the study of collections of open linkages in 3-space that
may be interlocked in the sense that the linkages cannot be
separated without one bar crossing through another. We consider
chains of bars connected with rigid joints, revolute joints, or
universal joints and explore the smallest number of chains and bars
needed to achieve interlock. Whereas previous work used topological
invariants that applied to single or to closed chains, this work
relies on geometric invariants and concentrates on open chains.
