Abstract
By means of having taken advantage of certain physical properties of solids with a manufacturing process of incrementally deforming hollow links, there is produced new hollow simulated diamond cut multifaceted jewelry rope chain, which results in a product weighing up to 60% less than its solid counterpart, but which in its aesthetic looks is similar to solid diamond cut jewelry chains, and furthermore, with a hardness greater than the same hollow chain that has not gone through the process. This invention presents a new diamond cut chain, which costs a fraction of the price of a solid chain aesthetically similar, and in which the chain may vary in cross-section, such as forming a square or a hexagon.
Claims21
A jewelry rope chain made of a number of intertwined links forming a double helix and resembling a rope, comprising:
- a plurality of segmented hollow links, said links having an annular configuration interrupted by an inner gap extending along an inner circumference of said hollow links,
- each of said hollow links having an outer surface wall portion generally curved in cross section which is spaced apart from, and has a center opposite, said inner gap, and,
- each of said hollow links having further at least one flattened portion formed in said curved outer surface wall portion, said at least one flattened portion extending inwardly toward said inner gap from said outer surface wall portion, said at least one flattened portion adjacent to at least one further flattened portion.
A jewelry rope chain made of a number of intertwined links forming a double helix and resembling a rope, comprising:
- a plurality of segmented hollow links, each of said links having an annular configuration with an outer surface wall portion generally curved in cross section which is spaced apart from, and has a center opposite, an inner wall portion, each of said hollow links further having at least one flattened portion formed in said curved outer surface wall portion and extending inwardly toward said inner surface wall portion with respect to said outer surface wall portion, said at least one flattened portion adjacent to at least one further flattened portion .
A jewelry rope chain made of a number of intertwined links resembling a rope, comprising:
- a plurality of segmented hollow links, said links having an annular configuration interrupted by an inner gap extending along an inner circumference of said hollow links, and said hollow links having an outside exterior circumferential surface and an inside interior circumferential surface,
- each of said hollow links having an outer surface wall portion generally curved in cross section which is spaced apart from, and has a center opposite, said inner gap, and,
- each of said hollow links having further at least one flattened portion on an outside exterior circumferential surface of said curved outer surface wall portion, said at least one flattened portion on said outside exterior circumferential surface of said curved outer wall portion extending inwardly toward said inner gap with respect to said outer surface wall portion.
A jewelry rope chain made of a number intertwined links forming a double helix and resembling a rope, comprising:
- a plurality of segmented hollow links, each of said links having an annular configuration with an outer surface wall portion generally curved in cross section which is spaced apart from, and has a center opposite, an inner wall portion, each of said hollow links further having at least one flattened portion on an outside exterior circumferential surface of said curved outer surface wall portion and extending inwardly toward said inner surface wall portion from said outer surface wall portion.
A jewelry rope chain made of a plurality of intertwined and segmented hollow annular links, each hollow annular link being formed from a wall which is tubular in cross section, said wall having a predetermined outside tubular diameter a predetermined wall thickness, said jewelry chain comprising:
- on said tubular wall an outer surface wall portion generally curved in cross section which is spaced apart from, and has a center opposite, an inner wall portion, each of said hollow links further having at least one flattened portion on an outside surface of said curved outer surface wall portion and extending inwardly toward said inner surface wall portion from said outer surface wall portion;
- said flattened portion extending toward said inner wall portion at a distance exceeding said predetermined wall thickness.
