BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring size bar for measuring the size of a ring.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view showing a conventional ring-size bar. Referring to FIG. 5, a conventional ring size bar 1 is formed of metal, and a grip portion 3 and a scale bar portion 2 are integrally formed. The scale bar 2 is at the base 2a
Is formed in a tapered shape whose diameter decreases toward the tip 2b. A scale 2c for measuring the size of the ring is formed as a groove on the peripheral surface of the scale bar portion 2.

In order to measure the size of a ring using such a ring size bar 1, the tip 2 b of a scale bar 2 is required.
Then, the ring portion of the ring is inserted, and the ring portion of the ring is moved to the base portion 2a side, and the inner surface of the ring portion and the scale bar portion 2 are moved.
Stop at the position where it comes into contact with the peripheral surface of. Scale 2 at this position
Read the size of the ring using c. like this,
The cross section of the scale bar portion 2 of the conventional ring size bar has a circular shape, and when the ring portion of the ring has a circular shape, there is no problem in the measurement method using such a ring size bar.

[0004]

However, if the ring is fitted on the finger for many years, the shape of the ring portion of the ring may be deformed and may not be circular, for example, elliptical. When the size of the ring is changed, it may be difficult to change the size of the ring in a circular shape. In this case, the shape of the ring is deformed. FIG. 6 is a side view for explaining such size correction. Referring to FIG. 6, a jewel 5 is attached to the ring portion 4,
The upper part of the ring part 4 to which the jewel 5 is attached is rarely modified when the ring is modified. In most cases, the lower part of the ring part 4 remote from the jewel 5 is modified to modify the ring. Therefore, when increasing the ring size, the size is corrected by lengthening the lower part of the ring portion 4. For this reason, only the lower part of the ring part 4 becomes long as shown by the chain line in FIG.
The entire shape of the ring portion 4 is no longer a circular shape but a shape close to an elliptical shape.

[0005] As described above, when the size of the ring portion of a ring deformed into an elliptical shape or the like due to long-term use or size correction is measured with a conventional ring size rod as shown in FIG. As shown in FIG. 7, the shortest diameter portion of the ring portion 4 stops at a position where it contacts the scale bar portion 2. For this reason, when measuring the size of the ring portion of the deformed ring with such a conventional ring size bar, the shortest diameter of the ring portion is measured.

[0006] However, the finger itself has elasticity as a whole, and when the ring is put on, the finger is slightly deformed along the shape of the ring. Therefore, whether or not the size of the ring portion of the ring fits the finger is a matter of the length of the inner circumference of the ring portion of the ring, and cannot be determined from the measured value of the shortest diameter of the ring portion of the ring. Therefore, when measuring the size of a ring using a conventional ring size bar, even if the ring portion of the ring of the specified size is too loose when fitted to a finger, the problem is that it does not fit. Occurred. Therefore, the conventional ring size bar has a problem that the size of a resized ring or the size of a ring that has been used and deformed for many years cannot be measured with practical accuracy.

Further, since the conventional ring-size bar is made of metal, there is a problem that the inner surface of the ring portion of the ring and the surface of the ring-size bar rub against each other during measurement, thereby damaging the inner surface of the ring portion of the ring. Furthermore, when measuring the size of such a ring, the jewel part of the ring may rub against the surface of the ring-size bar. For this reason, in the case of fragile jewels such as emeralds and Mexican opals, there has been a serious problem that the jewels are damaged. Also, when an impact is applied to a jewel by a ring-size bar, the jewel may be chipped or broken.

An object of the present invention is to solve such a conventional problem, and to measure an accurate size of a ring of a ring which has been deformed due to resizing or long-term use as the length of the inner peripheral surface of the ring. It is an object of the present invention to provide a ring-size stick that can be used and does not damage a ring portion of a ring, a jewel, or the like.

[0009]

The ring size bar of the present invention is a ring size bar for measuring a ring size.
So that the diameter decreases from one end to the other.
And the inner surface of the ring portion of the ring
Substantially change the length of the outer peripheral surface to conform to the shape
Without deforming the shape of its outer peripheral surface without
The length of the peripheral surface of the cylindrical elastic body
Scale to measure ring size along hand direction
It is characterized by being provided.

The material of the elastic body used in the present invention is preferably rubber or plastic. Also, a laminated paper or a cardboard obtained by laminating a plastic film or the like can be used. As a preferable degree of elasticity of the elastic body, it is preferable that the elastic body exhibits the same degree of elasticity as a finger when formed into a cylindrical body with an appropriate thickness. In this regard, urethane rubber is particularly preferable. For example, using urethane rubber, the thickness 1
３3 mm, particularly preferably about 2 mm, has a rigidity enough to support the entire cylindrical elastic body,
In addition, it is possible to exhibit elasticity capable of appropriately deforming according to the shape of the inner circumference of the ring of the ring.

[0011]

The present inventor has made various studies in view of the above-mentioned conventional problems, and as a result of using the elastic body as a material and forming it into a tubular shape, the rigidity is such that the entire body can be supported and the ring is deformed according to the ring portion of the ring. The present inventors have found that a ring-size rod having elasticity as much as possible can be obtained, and have reached the present invention.

In the present invention, since the tubular elastic body is used, the ring portion of the ring is inserted into the tubular elastic body. If the ring portion of the ring is deformed, the ring portion of the ring is fitted. The part of the cylindrical elastic body that is deformed according to the shape of the ring part, and the ring part is moved to the large diameter side until the surface of the cylindrical elastic body is exactly along the inner surface of the ring part,
The ring size according to the length of the inner peripheral surface of the ring portion can be measured.

One feature of the present invention is that a cylindrical elastic body is used. In other words, even if it is an elastic body that can be easily deformed, for example, if a sponge is used, when the ring of the ring is inserted and deformed, the length of the peripheral surface also changes due to the deformation. As a result, an accurate size cannot be measured. In addition, since the elastic body is used as the material in the present invention, the inner peripheral surface of the ring is not damaged when the size of the ring is measured by inserting the ring into the cylindrical elastic body. Also, it does not damage the jewels.

FIG. 1 is a perspective view showing a ring-size bar according to an embodiment of the present invention. Referring to FIG. 1, a ring-size bar 11 of this embodiment includes a grip portion 13 and a scale bar portion 12. The scale bar portion 12 has a base portion 12
It is formed of a tapered cylindrical urethane rubber whose diameter decreases from a to the tip 12b.
The grip portion 13 may be formed integrally with the scale bar portion 12, or may be formed from a separate component.

A scale 12c is formed on the peripheral surface of the scale bar 12 along the longitudinal direction. The scale 12c may be one written on the scale bar 12 by printing or the like, or one having a scale carved on the scale bar 12 and the surface, and is not particularly limited. The thickness of the cylindrical elastic body of the scale rod portion 12 is about 2 mm in this embodiment. The scale 12c has a size 28 in the vicinity of the base 12a and a size 1 in the vicinity of the tip 12b, and scales are formed for each scale from size 28 to size 1. In this example, size 2
The length from 8 to 1 is about 20 cm.

FIG. 2 is a sectional view taken along the line AA shown in FIG. As shown in FIG. 2, the scale bar portion 12
It has a circular shape when no force is applied from the outside. When the ring portion of the ring deformed into an elliptical shape is inserted into the scale bar portion from the tip portion 12b and moved toward the root portion 12a, as shown in FIG. The scale bar portion 12 is deformed in a shape along the shape. FIG. 3 shows a state in which the scale bar portion 12 is deformed along the inner peripheral shape of the ring portion 4 as described above. Further, the ring portion 4 may be moved to an appropriate position while forcibly performing such deformation of the scale bar portion 12 with a finger or the like.

The ring size bar of this embodiment can also be used to measure the ring portion of an undeformed circular ring. FIG. 4 is a cross-sectional view showing a state where such a circular ring portion 5 is fitted to the scale bar portion 12. By using the ring size bar of this embodiment, the scale bar portion 12 can be deformed according to the shape of the inner peripheral surface of the ring portion of the ring, and the scale bar having an outer periphery corresponding to the length of the inner peripheral surface of the ring portion of the ring. It can be moved to the position of the part 12. For this reason, the size according to the length of the inner peripheral surface of the ring portion of the ring can be measured. In addition, since the ring size bar of this embodiment is formed of urethane rubber, when measuring the ring size of the ring, the inner peripheral surface of the ring portion of the ring and jewels are not damaged.

[0018]

[Effect of the Invention] Since the ring size bar of the present invention uses a tapered cylindrical elastic body, even if the size of the ring portion of the ring is deformed due to long-term use or size correction, the inner circumference of the ring is not affected. An accurate size according to the length of the surface can be measured. Therefore, the use of the ring size bar of the present invention can solve the problem that even if the same size is used, the finger does not or does not fit. In addition, since the ring size bar of the present invention is made of a cylindrical elastic body, there is no possibility of damaging the ring portion of the ring when measuring the size, unlike the conventional ring size bar. There is no danger of damaging the jewelry.
