Abstract
A link chain has multiple individual chain links arranged in a repeating sequence. A first chain link has two shank portions connected by two arc portions which define an interior space. One or more dividing elements project inwardly from an inside surface of a shank portion and divide the interior space into two movement spaces. A second chain link has two shank portions connected by two arc portions which define a movement space within its interior. The second link is linked to the first link and movable within one of its two movement spaces. When a longitudinal axis of the second chain link is moved from an intended, substantially aligned position by less than 90 degrees, an outside of an arc portions of the second chain link that engages a movement space of the first chain link contacts the dividing element, and an inside of a shank portion of the second chain link contacts an arc portion of the first chain link.
