US 5,475,989 A · Foldable stiff metal chain necklace and bracelet

Abstract

According to the invention, a crimp and crease resistant metal chain necklace is provided which is composed of adjoining rigid metal chain segments preferably a flat stiff metal chain such as herringbone, serpentine or cobra chain made from a precious metal, preferably gold or silver. The ridged metal chain segments are of the type which are susceptible to crimping and creasing in ordinary usage and which cannot be folded without damaging the chain. The metal chain segments are interconnected by hinged connectors which are preferably integrally attached to such metal chain segments to provide a crimp and crease resistant chain which can be folded to a small size and preferably to about the length of the longest rigid metal chain segment. Preferably the hinged connector includes at least one rod about which the chain segments can pivot. Preferably the rod, is concealed within the necklace to give a smooth, flat appearance.

Dependent claims

A piece of jewelry comprising:

a. adjoining stiff metal chain segments that are susceptible to permanent creasing;
b. hinged connector means pivotly attaching each metal segment to the adjoining segment;
a first chain segment and a second chain segment adjoining said first chain segment;
said hinged connector means including a first and second pivot rod, said first pivot rod mounted to said first chain segment at one end thereof, said second pivot rod mounted to said second chain segment at the end adjoining said first chain segment so that the first chain segment can pivot about said first pivot rod independently of said second chain segment and said second pivot rod and vice versa;
whereby said jewelry can be folded at each hinged connector to a length approximately equal to the length of a longest chain segment without creasing the jewelry.

A necklace comprising:

a. at least three adjoining stiff metal chain segments that are susceptible to permanent creasing;
b. at least two hinged connector means pivotly attaching each metal chain segment to the adjoining segment;
c. each said hinged connector means including,
i. a first and second U-shaped keeper having a chain mounting end and a pivot rod attachment end;
ii. said first keeper affixed at said chain mounting end to a chain segment;
said second keeper affixed at said chain mounting end to a second chain segment, said second chain segment adjoining said first chain segment in said necklace;
iii. said first and second keeper having projecting legs separated by a hollow at said pivot rod attachment end;
iv. tubular keeper channels extending through said legs of said first and second keeper;
v. a coupling means having a first and second tubular coupling channels mounted in the hollow of both the first and second keeper;
vi. said first tubular coupling channel aligning with said tubular keeper channel in first said keeper;
said second tubular coupling channel aligning with said tubular keeper channel in said second keeper;
vii. a first pivot rod mounted through said first tubular coupling channel and said tubular keeper channels in said first keeper;
a second pivot rod mounted through said second tubular coupling channel and said tubular keeper channels in said second keeper;
whereby the adjoining metal segments are pivotly connected to one another so that said first chain segment pivots around said first pivot rod and said second chain segment pivots around said second pivot rod so that said necklace can be flatly folded at the hinged connector means to a length approximately equal to the length of a longest chain segment without creasing the necklace.
