ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a jewelry chain. More particularly, the present invention relates to an improved Jewelry chain.
2. Description of the Prior Art
Numerous innovations for chains have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.
A FIRST EXAMPLE, U.S. Pat. No. 1,655,763 to Fulford teaches an ornamental chain formed of a series of connected links, each having a body frame substantially heart-shaped in outline, and a head member including an integral bendable link-connecting hook-shaped neck portion extending upwardly from the plane of the bottom of the body frame, laterally extending wing portions on said head member arranged to extend across the frame opening to engage opposite sides thereof on bending of said neck portion, said neck portion being adapted to receive the body frame of an adjacent link and said wing portions acting to limit the movement of said received body frame about the neck portion.
A SECOND EXAMPLE, U.S. Pat. No. 2,007,445 to Goldenberg teaches an ornamental chain comprising a plurality of units of relatively soft metal, each unit consisting of horizontally convexo-concave body segments provided upon their forward ends with points and with abutments and at their rear ends with abutments, a cross bar connecting the forward abutments, a longitudinally disposed tongue between the segments adapted to receive the cross bar of an adjacent unit comprising an upwardly directed rear portion and a downwardly inclined forward portion, spacing bars connecting the rear abutments to the lower end of the rear portion of the tongue to loosely receive the points of an adjacent unit therebetween, and projections upon the segments fixed to the forward portion of the tongue.
A THIRD EXAMPLE, U.S. Pat. No. 5,636,506 to Yngvesson teaches a chain link and a method for the production thereof as well as a chain consisting of connected chain links and a connecting part for connecting chain links. The chain link consists of an endless elongated rod-like part which is characterized in that it is shaped as two pairs of loops and wherein the loops in each pair are substantially parallel and the pairs are arranged in two planes which are turned through 90 degrees with respect to each other. The connecting part consists of a semi-finished chain link and the chain consists of connected chain links as well as possibly connecting parts.
A FOURTH EXAMPLE, U.S. Pat. No. 5,664,410 to Nydick teaches a link and a chain formed therefrom, wherein the links comprise a shaft portion having first and second opposing ends defining therebetween a longitudinal axis for the link; an enlargement portion connected to the shaft portion at the first end, the enlargement portion having a width which is greater than a width of the shaft portion at the first end; and a mandorla shaped portion having first and second apertures therein, the mandorla shaped portion being connected to the shaft portion at the second end, and the apertures being shaped so as to prevent the enlargement portion from passing therethrough.
A FIFTH EXAMPLE, U.S. Pat. No. 6,055,802 to DiVietri teaches a chain
10
whose configuration can best be seen in
FIGS. 1-3
, and as such, will be discussed with reference thereto.
As shown in
FIG. 1
, the chain
10
is formed from a plurality of links
12
, each of which resembles a fish hook
14
and has a shank
16
with one end
18
thereof having a barbed hook
20
thereon and an opposite end
22
having an eyelet
24
thereon that engages the barbed hook
20
of an adjacent link
12
so as to form the chain
10
.
As shown in
FIG. 2
, the barbed hook
20
of each link
12
touches the shank
16
of an associated link
12
so as to be closed, except, as shown in
FIG. 1
, wherein the barbed hook
20
of one terminal link
12
does not touch the shank
16
so as to allow the barbed hook
20
of the one terminal link
12
to selectively disengage from the eyelet
24
of the other terminal link
12
so as to allow the chain
10
to be donned.
As shown in
FIG. 3
, the eyelet
24
of each link
12
lies in a first plane and the shank
16
and barbed hook
20
of each link
12
lie a second plane that is perpendicular to the first plane and which is flat, and as a result thereof, each link
12
does not lie flat on the skin of the user.
It is apparent that numerous innovations for chains have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, however, they would not be suitable for the purposes of the present invention as heretofore described.
SUMMARY OF THE INVENTION
ACCORDINGLY, AN OBJECT of the present invention is to provide an improved jewelry chain that avoids the disadvantages of the prior art.
ANOTHER OBJECT of the present invention is to provide an improved jewelry chain that is simple and inexpensive to manufacture.
STILL ANOTHER OBJECT of the present invention is to provide an improved jewelry chain that is simple to use.
BRIEFLY STATED, STILL YET ANOTHER OBJECT of the present invention is to provide an improved jewelry chain of a type having a plurality of links. Each link resembles a fish hook and has a shank with one end thereof having a barbed hook thereon and an opposite end thereof having an eyelet thereon which engages the barbed hook of an adjacent link. The eyelet lies in a first plane and the shank and barbed hook lie in a second plane that is perpendicular to the first plane. The improvements include the barbed hook not touching the shank, the eyelet being so sized so as not to allow the barbed hook of an adjacent link to pass therethrough, except for the eyelet of one terminal link being large enough to allow the barbed hook of the other terminal link to selectively disengage therefrom, and the second plane being arcuate so as to allow each link to lie flat on the skin of the user.
The novel features which are considered characteristic of the present invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the specific embodiments when read and understood in connection with the accompanying drawing.
