PIVOT CHAIN END FOR JEWELRY

Abstract

A pivot chain end for a jewelry is provided in the present embodiment. The pivot chain end has a 360 degree linking mechanism for chains having jewelry items which helps in arresting the improper fall issue of the necklace when worn by a wearer. The pivot chain end includes an O ring which is circular in shape linked with a back chain having an abutted cylindrical portion with a through hole and a metal disc having three flat flanks and one curved ridged side, wherein the metal disc allows the screw to pass through within the disc and connect the O ring, through a partially threaded body on the screw, thereby securing the metal disc with the O ring and enabling the O ring to freely rotate 360 degree axially as per movement of the back chain.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The embodiments herein will be better understood from the following detailed description with reference to the drawings, in which:

[0011] FIG. 1 illustrates a typical arrangement of a necklace having a rigid O ring which links back chain and jewelry items according to an embodiment mentioned herein;

[0012] FIG. 2 illustrates a 360 degree pivot end for jewelry which keeps jewelry items still even when back chain is rotated according to an embodiment mentioned herein;

[0013] FIG. 3 illustrates an exploded view of the 360 degree pivot end according to an embodiment mentioned herein; and

[0014] FIG. 4 illustrates a different linkage components forming the 360 degree pivot end according to one example embodiment mentioned herein.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0015] As mentioned, there remains a need for a mechanism or technique to provide a 360 degree linking mechanism for chains with jewelry items which helps in arresting the improper fall issue of the necklace when worn by a wearer. The technique should also provide to make the rotation easy to move even after long use. This should also prevent dust from going inside the mechanism during wearing of the necklace.

[0016] The present embodiments herein provides a 360 degree linking mechanism for chains with jewelry items which helps in arresting the improper fall issue of the necklace when worn by the wearer. This linking mechanism will Keep necklace part still as only the chain movement will be there, when the wearer face is turned. A small golden ball or cylindrical head is tied/linked between the chain and stud part which allows to rotate 360 degree comfortably. After lot of pull test we have finally reached to conclusion that the strength is enough to lift up to 1.5 Kg. Referring now to FIG. 1 through 4 to describe the various embodiments of the present invention.

[0017] FIG. 1 illustrates a typical arrangement of a necklace 10 having a rigid O ring which links back chain and jewelry items according to an embodiment mentioned herein. The necklace 10 consists of a front casting 11 which contains the precious stones and motifs and a gold chain called back chain 14 which needs to be fastened at the back using a clasp or a hook. The back chain and the front casting of the necklace are traditionally soldered together directly or by using a O-ring 12. Since this joint is stiff, whenever there is a movement of the casting, the O ring pushes the chain, which then twists resulting in uneven fall and sparkle of diamonds getting affected.

[0018] Now, the solution of preventing an uneven fall is depicted in FIG. 2 illustrating a 360 degree pivot end 100 for jewelry which keeps jewelry items 104 still even when back chain 102 is rotated according to an embodiment mentioned herein. Here, O ring will link with the back chain is capable of rotating freely 360 degree along an axis thus resulting in neckwear to adopt as per the collar bone and gravity balance of necklace fall this would prevent the uneven fall issue faced by the wearer of the necklace.

[0019] FIG. 3 illustrates an exploded view of the 360 degree pivot end 100 according to an embodiment mentioned herein. The pivot chain end 100 includes an O ring 106, a metal disc 108 and a bottom screw. In an embodiment, The metal disc 108 may preferably be made from gold or plated with gold. All the components may be made from any other metals like gold, silver, platinum, etc. but not limited to the embodiments mentioned herein.

[0020] In an embodiment, the metal disc may be specially treated with chemicals to provide a smooth surface of the metal disc which will allow low friction while rotation of the O ring and the screw. Here the O ring 106 may be circular in shape. In an example embodiment, the O ring may be of any other shape like rectangle, square, triangle, etc. but not limited to the embodiments mentioned herein. In an embodiment, the O ring 106 is linked with a back chain 102

[0021] FIG. 4 illustrates a different linkage components forming the 360 degree pivot end 100 according to one example embodiment mentioned herein. Here, an abutted cylindrical portion 106A is provided in the O ring which is having a through hole 106B. In an embodiment, the hole 106B may be threaded to accommodate a bottom screw 110 having a cylindrical head 110A.

[0022] In an embodiment, the screw may be partially threaded 110 C on body 110B of the screw in order to secure any article within the body of the screw. The metal disc 108 includes a three flat flanks 108A and one curved ridged side 108B. In an embodiment, the metal disc allows the screw 110 to pass through within the disc such that the cylindrical head of the screw rests within larger hole 108C of the metal disc on one side, the body 110B of the screw passing to other side from a smaller hole 108D connecting the O ring.

[0023] In an embodiment, the partially threaded body 110 C facilitates securing the metal disc with the O ring and enabling the O ring to freely rotate 360 degree axially as per movement of the back chain 102.

[0024] In one embodiment, one side of the metal disc may be welded with the chain 102 containing the jewelry 104. Here the metal disc may be made of any metal used in jewelry or otherwise. The O ring and the metal disc has a gap 112 in between them to allow the O ring to freely rotate 360 degree along the axis as per movement of the back chain with minimum friction.

[0025] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope.
