Patent Application
20070095104
The present invention relates to rings, and in particular to a ring device, wherein the assembly work can be performed easily and quickly. The ring is a metal ring. The pins clamp the jewel. No claws are used so that the ring will not hurt the clothes or other objects.
Referring to
However in assembling the prior art ring 1, the jewel 12 is placed upon the seat 11 and then the claws 110 serve to clamp the jewel 12. The machining work is tedious and time-consumed. Thereby the claws 110 easily crack clothes or other objects. Thereby the claws 110 deform and become loose as the jewel 12 is released. Moreover in the machining process of bending the claws 110 for clamping the jewel, it is possible that the claws 12 will crack or hurt the jewel 12.
Accordingly, the primary object of the present invention is to provide a ring device, wherein the assembly work can be performed easily and quickly. The ring is a metal ring. The pins clamp the jewel. No claws are used so that the ring will not hurt the clothes or other objects.
To achieve above objects, the present invention provides a ring device which is made of metal. The ring device comprises a ring body; two clamping pins extending from the ring body; a surface of the pin facing the pin having a first groove and a surface of the other pin facing the pin having a second groove; the ends of the pins expanding outwards so as to form with a clamping portion; a jewel placed in the clamping portion to be clamped by the two pins; edges of the jewel embedding into the first and second grooves to be fixed therein.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to FIGS. 3 to 6, the ring device of the present invention has the following components.
A metal ring body 2 has two clamping pins 20, 21. A surface of the pin 20 facing the pin 21 has a groove 200 and a surface of the pin 21 facing the pin 20 has a groove 210. The ends of the pins 20, 21 expand outwards so as to form with a clamping portion 22. A jewel 3 is placed in the clamping portion 22 to be clamped by the two pins 20, 21. Edges of the jewel 3 embed into the groove 200, 210 to be fixed therein.
In assembly, referring to FIGS. 3 to 6, a fixture compresses the ring 2 inwards so that the two pins 20, 21 expand outwards. Then the jewel 3 is placed in the clamping portion 22 so that the edges 30 of the jewel 3 are received into the grooves 200, 210 of the pins 20, 21. Then the fixture is released. Therefore, by the resilient force of the ring 2, the two pins 20, 21 will restore to clamp the positioning portion 22 of the jewel 3.
Advantages of the present invention will be described here. In assembling the jewel, the fixture clamps the ring from the two outer sides of the ring so that the pins expand outwards, and thus the edges of jewel can slide into the grooves 200, 210. The assembly work can be performed easily and quickly.
The ring is a metal ring. The pins clamp the jewel. No claws are used so that the ring will not hurt the clothes or other objects.
Furthermore, by sliding the edges of the jewels into the grooves, the assembly work is easy and quickly.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
