[Technical field to which the device belongs]

 The present invention relates to a ring whose size can be adjusted.

[0002]

[Prior art]

 Heretofore, as a ring which can be adjusted in size of this kind or which has a rotation preventing function, for example, Japanese Utility Model Laid-Open No. 60-20818, Japanese Utility Model Laid-Open No. 61-18012, Japanese Utility Model Laid-Open No. 61-121119 are known. Some of them are provided with a slide portion so that the diameter of the ring can be adjusted, as described in the official gazettes, Japanese Utility Model Publication No. 62-164816 and Japanese Utility Model Publication No. 2-109415. In addition, there is also known one such as disclosed in Japanese Utility Model Laid-Open No. 63-124807, which is provided with a decorative band portion similar to a watch band so that fine size correction can be easily performed. Further, JP-A-60-18105, JP-A-1-34301, JP-A-57-85216, JP-A-59-21405, JP-A-62-177309, and JP-A-62-155610. No. 5/9314, etc., and as shown in FIG. 5, a size adjusting piece 12 formed on a curved surface along the inner peripheral surface of the ring portion 11 is provided so that the diameter of the ring can be adjusted. What has been developed is being developed.

[0003]

[Problems to be solved by the device]

 However, each of the above conventional examples has the following drawbacks.

[0006] The slide having a slide part so that the diameter of the ring can be adjusted has a drawback that the structure is complicated to be incorporated in a small structure such as a ring and it is difficult to hold the ring in a predetermined size.

In addition, in the case where the decorative band portion similar to the watch band is provided, the structure is too complicated in a small size such as a ring, and the connecting portion of the decorative band is easily soiled. In addition, there was a problem in that the design was also noticeable and the overall decorativeness was impaired.

Further, in the case where the ring diameter can be adjusted by providing the size adjusting piece formed on the curved surface along the inner peripheral surface of the ring, the detaching operation is troublesome and easy to be lost, and moreover, it is inserted into the finger. If it is attached before the operation, it will interfere with the operation of inserting the ring into the finger, and if it is attached after inserting it into the finger, the operation of attaching it to the ring will be troublesome.

Therefore, the inventor has previously described the utility model registration number No. 3015507, and as shown in FIG. 6, configures the ring main body 21 with the ring 22 and the base 23, and forms a curved surface along the inner peripheral surface of the ring 22. And an elastic size adjusting piece 24 whose one end is attached to the inner circumference of the ring 22 by a rotary shaft 25, and which is held along a groove 26 provided on the inner peripheral surface of the ring 22. In this case, we devised a ring that would be used with a normal ring size, and would be used with a size equal to or smaller than the normal ring size when it is inverted and held in a state of overhanging from the inner peripheral surface of the ring 22.

However, even in the ring of the present invention, it is necessary to axially attach one end of the elastic size adjusting piece 24 to the inner circumference of the ring 21, and in a small ring, the size is adjusted to the inner circumference of the ring 21 by the rotary shaft 25. The work of attaching the piece 24 is very troublesome, and a problem is likely to occur, and it is difficult to hold the size adjusting piece 24 in a predetermined position, which is difficult to handle.

The ring of the present invention eliminates the above-mentioned drawbacks of the conventional example, has a simple mechanism for holding the size adjustment piece in a predetermined position, and has an excellent decorativeness because it is easy to give a sense of unity as a whole, Moreover, the aim is to provide a ring with excellent commercial value that will not come off during use.

It is the main body. A size adjusting piece 6 having elasticity is attached to the inner peripheral surface of the ring of the ring body 1. This size adjusting piece 6 is basically a plate-like body, and one piece is formed into a concave shape along the inner peripheral surface of the ring to form a concave piece 7, and one end thereof is folded back to form a convex shape. The convex piece 8 is formed. The concave piece 7 of the size adjusting piece 6 is detachably housed in the groove 9 formed on the inner circumference of the ring.

As the material of the size adjusting piece 6, not only a metal plate to which elasticity is given by heat treatment or the like but also materials such as high-performance plastic, rubber having the same purpose, and hard rubber can be used. In this case, the material such as rubber or hard rubber may be a block body.

In the normal state, the size adjusting piece 6 is housed in the groove 9 formed with the concave piece 7 on the inner peripheral surface of the ring and is buried in the inner peripheral surface of the ring to affect the appearance and function of the ring. There is no such thing.

On the other hand, the convex piece 8 of the size adjusting piece 6 is held in a state of protruding in an arc shape from the inner peripheral surface of the ring. If this storage portion is tightly attached, or if it is prevented from coming off by the guide 10 provided in the groove 9, it can be held in a state of protruding in an arc shape from the inner peripheral surface of the ring, and the storage portion or guide. By press-fitting into 10, it becomes detachable.

When using the ring of the present invention, by pushing the finger into the ring against the elasticity of the convex piece 8 of the size adjusting piece 6, the finger is fitted regardless of the size or change of the size of the finger. Can be used in the state.

Therefore, for example, even when the knot portion of the finger is thicker than the other portions, the user can push the finger against the elasticity of the convex piece 8 of the size adjusting piece 6 and the size adjusting piece 6 will be pushed. Due to its elasticity, it can be easily put on the finger by retracting along the inner peripheral surface of the ring, and the convex piece 8 of the size adjusting piece 6 returns to its original position after the wearing and surely contacts the finger. The feeling of use is good, and the ring does not rotate around the finger during use.
