Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring size measuring instrument capable of easily and accurately measuring an optimal size of a ring desired to be worn.

[0002]

2. Description of the Related Art In recent years, in the jewelry industry, wedding rings, engagement rings and various other fashion rings have been remarkably increased. One of the features is the appearance of wide rings.

Conventionally, ring size measuring tools in Japan and around the world seem to fit from each of the number rings r having a width dimension of about 2 mm locked to a large ring R, as shown in FIG. The wearer's finger is selected and the measurement is performed.

The measurement site at this time is mainly the center of the proximal phalangeal joint and the proximal interphalangeal joint of the wearing finger, and an accurate numerical value may not be obtained with a measuring tool having a width of 2 mm.

[0004] It is common knowledge that the thickness of fingers varies slightly depending on physical condition and measurement time. In particular, women tend to declare the number of patterns as few as possible and purchase rings,
It is also a cause of trouble at the buyer and the dealer at a later date.

[0005]

SUMMARY OF THE INVENTION The present invention makes it possible to easily and accurately measure the optimal size of a ring to be worn,
A ring size measuring instrument is provided.

[0006]

In order to solve the above-mentioned problems, the present invention provides seven types of ring bodies having the same inner diameter and width dimensions of 1 mm to 5 mm, 10 mm and 20 mm, respectively.
It is a group and consists of a plurality of groups of different numbers with different inner diameters. It is easy to combine each ring body of 1 mm to 5 mm, 10 mm and 20 mm, and to provide a connecting or joining means that can freely contact and separate, and the material of the ring body is It was made less susceptible to climate, weather conditions, etc.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, wherein 1 is a group of ring bodies having the same inner diameter and different width dimensions, 1a is a 1 mm wide ring body made of ferrite magnet, and 2a is also a 2mm wide ring body. The ring body, 3a is a ring body of 3 mm width, 4a is a ring body of 4 mm width, 5a is a ring body of 5 mm width, 6a is a ring body of 10 mm width, and 7a is a ring body of 20 mm width.

Since the left side of each ring has magnetic properties of the south pole and the right side has magnetic properties of the north pole, the ring bodies 1a to 7a
Are connected integrally. (To make it easier to understand,
Each of the ring bodies 1a to 7a is shown separately.

Now, when measuring the inner diameter size of a 14 mm wide ring, the number of the size declared or stored by the purchaser (hereinafter referred to as the number), for example, if the number is 10, the number is 10 and before and after it. The ring body 4a and the ring body 6a are respectively extracted from the group of Nos. 9 and 11, and first, both the ring bodies 4a and 6a of No. 10 are combined. Then, it fits into the finger of the purchaser who wants to wear it and checks the fit. Next, wear the No. 9 and No. 11, compare and examine the three, and determine the optimal size. L is each ring body 1a-7
In the inner diameter of a, M is a number indicating the width dimension.

FIGS. 2 (a), 2 (b) and 2 (c) show other connecting means of each of the ring bodies 1a to 7a. The material is stainless steel.

An engagement notch 4 is provided on the right side of the top 2 and bottom 3 of the ring 1a, and a locking projection 5 is formed on the left side of the top 2 and bottom 3 of the adjacent ring 2a. An engagement notch 4 is provided on the right side surface, an engagement notch 4 is similarly provided on the right side surface from the ring body 3a to the ring body 6a, and only the locking projection 5 is provided on the left side surface of the ring body 7a. I have.

The ring bodies 1a to 7a can be easily separated by turning one of them clockwise and rotating the other counterclockwise. When connecting, the reverse may be performed.

FIGS. 3 (a), 3 (b) and 3 (c) are views showing other joining means of each of the ring bodies 1a to 7a, and are mainly suitable for a synthetic resin material.

A hemispherical recess 6 is provided on the right side of the top 2 and the bottom 3 of the ring body 1a, and a hemisphere slightly larger than the recess 6 is provided on the left side of the top 2 and the bottom 3 of the adjacent ring 2a. Are formed, and the ring body 6a is formed from the ring body 3a.
Similarly, a hemispherical concave portion 6 is formed on the right side, a hemispherical convex portion 7 is formed on the left side, and only a hemispherical convex portion 7 is formed on the left side of the ring body 7a.

To separate the ring bodies 1a to 7a, the right and left thumbs are placed near the top 2 of the ring body to be extracted and each hand is tilted to the back side. In the joining, the concave portion 6 and the convex portion 7 are made to correspond to each other and pressed from right and left.

[0017]

The present invention has the following effects because it is configured as described above.

Each of the ring bodies 1 a to 7 a having different width dimensions
Can be easily combined, so that the inner diameter of the same width as the ring to be worn can be accurately determined without being affected by physical condition, time, and the like, and troubles at a later date can be prevented.

The ring can be easily adapted to foreigners with long wearing parts (joint width), and the material of the ring is not affected by climate, weather conditions, etc., so that it can be used all over the world.

Each of the width dimensions is 1 mm to 5 mm and 10 mm.
Since the seven types of ring bodies 1a to 7a of mm and 20 mm are configured as one group, the dimension measurement of 1 mm to 45 mm is possible.

When the measuring instrument of the present invention is not used, it is conveniently stored in the case C for each group 1 as shown in FIG.
