Description

  The present invention relates to a metal ring to which a jewel is attached.

Conventionally, jewelry rings have been molded from metals such as gold, silver, and platinum.In addition, the pedestal is integrally formed on the ring body to show luxury, and the pedestal is made of diamond and opal. And the like are directly fitted and attached by bonding (for example, see Patent Document 1).
JP-A-9-51809 (page 2-3, FIG. 1)

  By the way, in a ring to which a jewel is attached as described above, when a bending force is applied to the ring main body, unnecessary stress is generated in the ring main body including the pedestal portion, and thus, for example, the pedestal portion is distorted and deformed. In some cases, the jewel may come off the pedestal or the jewel may crack. In particular, the case where gemstones are fitted and mounted in places other than the pedestal portion was serious. For this reason, at present, it is not possible to cope with the usual size adjustment for adjusting the inner diameter of the ring main body. Therefore, in such a case, a ring body having a size suitable for the size of the customer's finger is manufactured from the beginning, but the manufacturing requires not only a large number of days (for example, 40 days). However, there has been a problem that the manufacturing cost is high and cannot be reduced.

  Therefore, the present invention has been made to solve the above-mentioned problem, and the size of the ring main body is set so that even if the size is changed, the directly fitted jewel does not come off from the ring main body or the jewel is broken. It is an object of the present invention to provide a ring that can be repaired, the period of which can be shortened as compared with the related art, and the manufacturing cost can be reduced.

  In order to achieve this object, the ring according to the present invention is a ring that is mounted by directly fitting a jewel into a metal ring body, and has a flexible portion that is freely bent at a part of the ring body. The flexible portion is formed by connecting a plurality of ring units whose length can be freely adjusted in a chain shape.

  For example, when the inner diameter of the ring body is reduced by resizing, one of the plurality of ring units is cut in a direction orthogonal to the connection direction and a predetermined width is cut in the connection direction. Then, the two cut end faces are put together and brazed. When the inner diameter of the ring body is to be increased, one of the plurality of ring units is similarly cut in a direction perpendicular to the connecting direction, and a metal piece having a required width equivalent between the two cut end faces is similarly cut. And brazing.

  In any of the above cases, since the ring units whose length can be adjusted to be shorter or longer are connected in a chain shape, no bending force is applied to the ring main body. As a result, unnecessary stress is not generated in the ring main body including the pedestal portion, so that the mounted jewel does not come off or crack.

  In the ring according to the present invention, since the ring units whose length can be freely adjusted are connected in a chain shape, even if any of the ring units is shortened or lengthened, the bending force is applied to the ring body. Will not join. Therefore, even if the size is changed, unnecessary stress is not generated in the ring main body, so that the directly fitted jewel does not come off or the jewel is not broken. Thereby, the size of the ring main body can be changed. Further, there is an advantageous effect that the period can be shortened and the manufacturing cost can be reduced as compared with the related art.

  Hereinafter, embodiments of the ring according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the ring viewed from the front, and FIG. 2 is a perspective view of the ring viewed from the rear. This ring A is made of a metal ring main body 1, and three pedestals 2, 2, 2 are integrally formed on the upper part thereof so as to be located at the vertices of an equilateral triangle. Is mounted. Further, a semi-precious stone 3a such as white topaz is also attached to the shoulder 1a of the ring body 1.

  A mounting hole 4 is formed in each of the pedestals 2, and the jewel 3 is directly fitted into the mounting hole 4 and fixed. As shown in FIG. 3, the shoulder 1a is provided with a gap 5 extending vertically along the longitudinal direction thereof, and the semi-precious stone 3a is directly fitted and fixed to one side thereof. Most of these gems 3 and semi-precious stones 3a are fixed together with an adhesive. As the ring body 1, for example, a noble metal such as gold, silver, platinum, or an alloy of gold and silver is used. Further, as the jewel 3, various jewels such as diamond, emerald, sapphire, opal, and ruby are used.

  A flexible portion 6 is provided at a lower portion, which is a part of the ring main body 1, to bend freely over about a half circumference thereof. The flexible portion 6 is configured by connecting a plurality of short ring units 7a and 7b in a chain shape.

  More specifically, two ring units 7a, 7a are arranged at both ends 1b, 1b on the upper side of the ring main body 1, respectively, and the ring units 7a, 7a at the lower ends thereof are combined by one ring unit 7b. Connected. Each of the ring units 7a, 7b is made of the same material as the ring main body 1. As shown in FIG. 4, the two ring units 7a, 7a on both sides are each provided with a convex portion 8 at one end and a second end at the other end along the connecting direction. It is formed by providing a concave portion 9 into which the convex portion 8 can fit. Convex portions 8 are provided at both ends 1b, 1b of the ring main body 1. The central ring unit 7b has concave portions 9, 9 at both ends since the convex portions 8, 8 of the adjacent ring units 7a, 7a are located on both sides thereof.

  Pin holes 10 and 11 are formed on both sides of each of the convex portions 8 and each of the concave portions 9 so as to communicate with each other in a fitted state. The ring units 7a and 7b are flexibly connected by fitting the respective protrusions 8 into the respective recesses 9 and inserting the pins 12 into the respective pin holes 10 and 11. The connection structure of the ring units 7a and 7b is not limited to this method, and may have another configuration as long as it is freely bent. In addition, both ends of each of the pins 12 are originally provided integrally with each of the ring units 7a by brazing, and the end faces thereof are also erased cleanly.

  The ring A according to the present invention has the above configuration, and is used by being inserted into a finger as shown in FIG. In this case, since the flexible portion 6 bends freely, it fits well on the outer peripheral surface of the finger Y, has good fitting comfort, and does not feel cramped.

  When the ring A is fitted to the finger Y for a long time, and the size of the ring A is to be changed, the following procedure is performed. That is, when the finger Y becomes thinner and the inner diameter of the ring A becomes smaller, the ring unit 7b located at the center of the flexible portion 6 is cut in a direction orthogonal to the connecting direction as shown in FIG. Then, a predetermined width is cut in the connecting direction, and the cut end faces 13, 13 are joined and brazed. Thereby, the ring main body 1 having a required inner diameter can be formed. Thus, even if the ring unit 7b, which is a part of the flexible portion 6 formed in a chain shape, is shortened, unnecessary stress is not generated due to the bending force applied to the ring main body 1.

  Next, when the finger Y becomes thicker and the inner diameter of the ring A is increased, as shown in FIG. 6B, the ring unit 7b located at the center of the flexible portion 6 is moved in a direction orthogonal to the longitudinal direction. They are cut and brazed with metal pieces 15 of the same length interposed between the cut end faces 14 and 14. Thereby, the ring main body 1 having a required inner diameter can be formed. Also in this case, the bending force is not applied to the ring main body 1 in the same manner as described above, so that unnecessary stress does not occur.

  As described above, in the ring A according to the present invention, the inner diameter of the ring main body 1 can be adjusted to be small or large by cutting one of the ring units 7a and 7b. In addition, since unnecessary stress is not generated due to the bending force applied to the ring main body 1, the jewelry 3 and the semi-precious stone 3a which are directly fitted and fixed to the pedestal portion 2 and the shoulder portion 1a even when the size is adjusted are also there. It does not come off or break. Thereby, the ring main body 1 can be resized. In addition, this size change can be completed in about one week, for example.

  Alternatively, a plurality of rings A having different inner diameters of the ring main body 1 may be manufactured in advance in a stepwise manner, and the length of the ring units 7a and 7b may be adjusted according to the customer to finish the ring.

  In the present embodiment, five ring units 7a and 7b are arranged on the flexible portion 6 and the center ring unit 7b is cut off, but this is in consideration of the balance between the right and left sides in appearance. Therefore, if possible, the number of the ring units 7a, 7b is preferably an odd number of 5, 7, 9,..., But may be an even number if there is no problem. Further, the ring units 7a and 7b of the flexible portion 6 are made of the same material as the ring body 1, but may be made of a different material.
