A rope chain is made from hollow rectangular links having a trapezoidal cross section. The wider parallel surface of the trapezoid is the outer periphery of the shaped link and is the primary surface of the finished rope chain. The narrower parallel surface of the trapezoidal shape, having a channel which forms a longitudinal seam running around the inside of the link, is an inside surface of the finished rope chain and is not visible in a finished chain. The other two sides of the trapezoid converge in symmetrical relationship to the parallel surfaces, and include an angle that approximately equals 360.degree. divided by the number of links required to form a single cycle of links in a double helix, as viewed in an end view of the rope chain. Adjacent links abut, planar surface to planar surface, and form a close fitting circle with a smooth external surface for the rope chain. |

The present invention(s) seeks to protect Applicant's link, link chain and methods of making, transforming and using such. The link, for use in series to form a multi-positionable link chain includes a through hole and a first and a second diagonal channel on a top and a bottom side running in opposite directions. Generally, the geometry of the links, and specifically, material removed from and/or sharpened edges of the through hole, the diagonal channels and/or corner portions of the modified rectangular solid links, is such to allow for relative rotation and/or multiple points of connection of adjacent links. The link chains of the present invention(s) are flexible in the length, width and height dimensions to allow adaptable transformation in a plurality of stable configurations. And they can include a clasp for ornamental and/or decorative use. |

A chain link of hollow construction and substantially uniform thickness, for intertwining with other chain links to form a jewelry chain, has a non-annular cross-section throughout the link with the cross-section being symmetric along a centerline plane through said cross-section. The cross-sectional shape of the link preferably has on each side of the centerline plane, at least two sides that meet at a point of inflection. On each side of the centerline plane, at least one side preferably converges toward said centerline plane. A reduction in manufacturing costs and precious metal used to form the links and therefore the chain is realized by using a non-annular cross-section having such constructional qualities. |
