[Industrial applications]

 The present invention relates to a size-adjustable ring that does not require a troublesome size adjustment of the ring, can be easily fitted over the joint part of the finger, and can be fitted exactly in the finger.

[0002]

[Prior art]

 Heretofore, as rings capable of adjusting the size of this kind, there are Japanese Utility Model Laid-Open Nos. 57-37318, 60-20818, 60-20819 and 61-61. Some of the inventions described in Japanese Patent No. 18012, Japanese Utility Model Laid-Open No. 61-112119, Japanese Utility Model Laid-Open No. 62-164816, and Japanese Utility Model Laid-Open No. 4-104912 make the ring part expandable and contractible.

Further, a well-known ring portion has an open end portion, and the interval between the open end portions can be adjusted, or the open portion such as the device disclosed in Japanese Utility Model Laid-Open No. 60-13016 is used. There is a ring connected by an elastic body.

Further, JP-A-59-21405, JP-A-60-18105, JP-A-1-34301, JP-A-57-172516, JP-A-63-27119, and JP-A-63-27119. A ring in which an adjusting member is fitted to the inner circumference of the ring portion so that the diameter thereof can be adjusted is also devised, as in the invention described in Kaihei 5-65214.

Although not a ring whose size can be adjusted, a ring in which the inner diameter of the ring is uneven so that it can be adapted to fingers of a plurality of sizes is also disclosed in Japanese Unexamined Patent Publication No. 1-320005. It is described in JP-A-57-47916, JP-A-61-105011, and the like.

[0006]

However, in the conventional example in which the ring part can be expanded and contracted, since the ring part is partially opened and the open end is crossed, the width or width at that part is crossed. There was a drawback that the ring portion was deformed in the thickness direction, causing a feeling of discomfort when it was visually or worn.

In addition, the size of the known ring portion having an open end portion and the gap between the open end portions being adjustable, and the ring having the open portion connected by an elastic body can be adjusted. Although it has the advantage of having it, it has the drawback that it gets out of shape or, in extreme cases, falls off when worn.

Further, in a ring in which an adjusting member is fitted to the inner circumference of the ring portion so that its diameter can be adjusted, it is necessary to prepare a plurality of adjusting members of different sizes to be attached to the ring portion. Since the size is small, it is troublesome to handle and it is easy to lose. There was also the drawback that it took a lot of time to attach it to the ring.

A ring in which the inner diameter of the ring portion is uneven so that it can be adapted to fingers of multiple sizes is not a fundamental solution, and it still has a drawback of causing discomfort in appearance and wearing. there were.

The present invention solves the above-mentioned drawbacks of the conventional example, and there is almost no discomfort at the time of appearance or mounting, and it can be mounted securely, and it is easy to handle and the adjustment work of the ring part is quick. The aim is to provide a ring that can be adjusted in size.

[0011]

[Means for Solving the Problems]

 In other words, the size-adjustable ring of the present invention partially opens the part of the ring portion that constitutes the ring, which substantially contacts the back surface of the finger, and has a screw part at one of the open ends and an insertion rod at the other end. The threaded portion and the insertion rod are connected by a connecting member provided with a threaded portion and a holding portion that engage with the threaded portion and the insertion rod, respectively, and the threaded portion of this connecting member is rotated. The size of the ring portion can be adjusted by adjusting the distance between the open ends.

Further, the size-adjustable ring of the present invention is also characterized in that the connecting member is provided with the screw portion and the holding portion in series in the above.

Further, the size-adjustable ring of the present invention is also characterized in that the connecting member is provided with the screw portion and the holding portion in parallel.

[0014]

[Action]

 The size-adjustable ring of this invention has the above-mentioned structure, so that it hardly feels uncomfortable when it is worn or worn, and it can be worn securely, and it is easy to handle and the ring can be adjusted quickly. Now you can do it.

[0015] Furthermore, even when the finger is worn over the joint of the finger, the size can be adjusted before and after the joint so that the finger can be easily worn.

Further, since the threaded portion to be formed need only be formed in one direction, the connecting member can be manufactured at low cost, and the product can be provided at low cost.

[0017]

【Example】

 An embodiment of a size-adjustable ring of the present invention will be described in detail below with reference to the drawings.

1 to 3, reference numeral 1 denotes a ring, which is composed of a pedestal 2 to which a jewel 3 is attached and ring portions 4 extending from both ends thereof. Then, a part of the ring portion 4 constituting the ring 1 that substantially contacts the back surface of the finger is partially opened, and the open end thereof is connected by the connecting member 5.

A screw portion 6 is provided at one opening end of the connecting member 5. A shaft cylinder 7 is provided at the other open end. A threaded portion 8 that engages with the threaded portion 6 is formed at one open end of the ring portion 4, and a support shaft 9 that engages with the barrel 7 is provided at the other open end of the ring portion 4. Is forming.

The connecting member 5 can be surely connected to the ring portion 4 by being fitted and attached to the open end of the ring portion 4.

Therefore, when the connecting member 5 is rotated, the screw portion 8 engages with the screw portion 6 and moves forward and backward. At that time, the shaft cylinder 7 freely rotates around the support shaft 9 and does not hinder the rotation of the screw portions 6 and 8. In this way, the length of the engaging portion between the screw portion 6 and the screw portion 8 changes, so that the diameter of the ring portion 4, that is, the size of the ring 1 can be easily adjusted.

Of course, it is desirable that the size can be adjusted at intervals of No. 1 or No. 2 at the most. The problem of making it easier occurs.

4 to 7 show another embodiment of the size-adjustable ring 11 of the present invention. FIG. 4 shows the case where the connecting member 15 is used in the vertical position of the ring portion 14, and FIG. 5 shows the case where the connecting member 15 is used in the vertical position of the ring portion 14.

In either case, the internal structure is formed as shown in FIGS. 6 and 7. That is, the connecting member 15 is composed of a threaded portion 16 provided at one opening end and a shaft cylinder 17 provided in parallel with the threaded portion 16 at the other opening end. The screw portion 16 is held in a holding frame 21 which is integral with the shaft cylinder 17, and is rotated in a state of being housed in the holding frame 21 by turning a knob 22 formed on the outer periphery by knurling or the like. Has become.

A screw portion 18 that engages with the screw portion 16 is formed at one open end of the ring portion 14, and a support pin 19 that engages with the shaft cylinder 17 has the other open end of the ring portion 14. Is formed in the part.

The connecting member 15 can be surely connected to the ring portion 14 by being fitted and attached to the open end portion of the ring portion 14.

Then, when the threaded portion 16 of the connecting member 15 is rotated, the threaded portion 18 engages with the threaded portion 16 and moves back and forth. At this time, the shaft cylinder 17 freely rotates around the support pins and does not hinder the rotation of the screw portions 16 and 18. In this way, the length of the engaging portion between the screw portion 16 and the screw portion 18 changes, so that the diameter of the ring portion 14, that is, the size of the ring 11 can be easily adjusted.

[Effect of device]

 The size-adjustable ring of this invention has the above-mentioned structure, so that it hardly feels uncomfortable when it is worn or worn, and it can be worn securely, and it is easy to handle and the ring can be adjusted quickly. Now you can do it.

Further, even when it is attached to the finger beyond the joint of the finger, it can be easily attached by adjusting the size before and after the joint.

Further, since the screw portion to be formed need only be in one direction, the connecting member can be manufactured at low cost, and the product can be provided at low cost.
