ABSTRACT:

The present invention relates to a new and improved construction for an expandable chain of particular use for costume jewelry.
BACKGROUND OF THE INVENTION
Chain constructions are utilized in the jewelry arts, both to support other jewelry objects, such as pendants, and as objects of body adornment themselves when formed into bracelets, rings and the like. Typically, the chains are non-extensible, and therefore must be carefully sized to meet the requirements of the wearer.
Tatoos, decorative ornamentation applied directly to the skin, often through a non-reversible process, represent a different methodology of body adornment. Because of the non-reversible nature of the tatoo application process, coupled with the time, cost and sometimes pain which is associated with the process, tatoos are often not considered by those who would otherwise be favorably disposed towards a product yielding such an appearance of adornment for themselves.
It is accordingly a purpose of the present invention to provide a jewelry chain construction which is of an extensible nature allowing jewelry items formed of the chain to conform to differently-sized portions of the body upon which the resulting jewelry item is applied.
It is a further purpose of the present invention to provide a jewelry chain construction which can be found in a variety of adornment objects, such as rings, bracelets and necklaces.
Another purpose of the present invention is to provide a jewelry chain construction which can simulate a tatoo-like design without in any way defacing the skin and which allows the design to be removed or relocated by the wearer as desired.
BRIEF DESCRIPTION OF THE INVENTION
In accordance with the foregoing and other objects and purposes, the jewelry chain construction of the present invention comprises interconnected lengths of a flexible chain-forming, generally inextensible monofilament material. Each length of the monofilament material may comprise one or more generally parallel individual monofilament elements formed into a series of loops, which may either be overlapping or spaced along the length of monofilament material. The loops of a first monofilament length encircle a second monofilament length at spaced locations, while the loops of the second monofilament length encircle the first monofilament length at spaced locations, yielding an extensible open multiple loop chain construction. The adjacent ends of the interconnected monofilament lengths may be joined together to prevent the chain construction from unraveling. The combination of the series of loose interconnected loops and the monofilament line material provides a chain construction which has resiliency which allows the construction to stretch along its longitudinal axis thus that, when the chain is formed into a closed construction, such as a bracelet, and placed on a limb, such as a wrist, a properly-sized looped chain construction fit firmly, but gently upon the wrist while displaying the loop structure. So displayed, the appearance of the construction can simulate a tatoo-like design, without any of the disadvantages associated with tatoos.
A plurality of chain constructions formed of first and second monofilament elements may be further interconnected along their respective lengths to create chain designs of differing widths. In addition, the formed loops may be of differing sizes along the monofilament lengths.
