We investigate when thick 3D polygonal chains are locked, i.e.,
have a disconnected configuration space. In particular, we show that thick
4-chains are never locked, and we exhibit a class of locked thick 5-chains
whose ratio of maximum edge length to minimum edge length is strictly less
than 3 (the best known ratio for nonthick chains).
