Abstract
A non-back-bending chain having a plurality of links wherein said links include a rounded portion, a right flat portion, a bottom portion, and a left flat portion. The rounded portion allows the chain to bend or coil in one direction. The flat portions, when in contact, prevent the chain from bending in the opposite direction. Therefore, a chain that can be used to both “push” and “pull” is provided. Further, the chain can be used to provide a rigid extension that can be used to support a force even when only supported by one end. The chain can be retracted for storage and bunched or coiled.
