Abstract

To provide a ring gauge for a ring which enables selection of an optimum size since it is difficult to measure the size of the ring at the proximal joint because it is difficult to pass through the second joint with a simple circular ring gauge for the ring. A part of a circular ring is provided with protruding parts 1(B) and 2(B) smaller than half of the circumference, or a shape 3(B) in which a part of the circle is cut off, and the second joint is passed through. Sometimes the protruding part or the cut part is turned sideways, and at the base part, the ring is rotated so that the protruding part or the cut part is on the back side of the hand or on the palm side. The circular part is attached to the finger to measure the optimum size of the finger. Then, the ring gauges of each number were made into a set. [Selection drawing] Fig. 1

Description

There is a standard for the size of the ring, for example, from 1 to 30 depending on the inner diameter.
No. 1 has a ring inner diameter of 13 mm, and No. 30 has a ring inner diameter of 22.66 mm. The inner diameter of the ring increases by 0.33 mm each time the number increases by one from No. 1. For example, the inner diameter of the ring for No. 4 is 14 mm. The present invention relates to a ring gauge for a ring (hereinafter referred to as a ring gauge), which is an instrument for measuring the optimal ring size.

Finger sizes vary from person to person, and various types of ring gauges have been proposed, which are devices that allow a person to select the optimum ring size for each person.

The idea of Patent Document 1 is that each number type ring is crimped with a pin on one side and has a structure that can be opened and closed on the other side. This is a ring size measuring tool that allows the user to select the optimal size.

The idea of Patent Document 2 is that a predetermined number of ring gauges of individual sizes are bound together, the ring gauges of each size are made of molded plastic products, and the sizes are indicated on the ring gauges of each size. is.

The device of Patent Document 3 has holes of each ring size in a template of a plastic molded product that serves as a base, and each size is displayed. Then, templates with different ring sizes are superimposed, fixed at the rotating shaft, and rotated in a fan shape.

The optimal ring is not determined solely by the diameter and circumference of the finger of the person who wears the ring, but factors such as the cross-sectional shape of the person's finger, the fleshiness of the finger, the thickness and hardness of the skin, etc. .
Therefore, it is best to select an optimal ring, including the feel of the finger when worn. For that reason, instead of simply measuring the diameter of the proximal segment with an opening and closing circular object, it is a good way to determine the size by actually fitting the actual ring or something similar to the proximal segment. is.

However, even if you try to determine the number (size) of the ring by simply fitting a circular ring, there is a difference between the proximal joint width and the proximal joint thickness of the second finger joint. It doesn't fit easily.
Therefore, there is a need for ring gauges of various sizes that can be easily passed through the second joint and that can be fitted to the proximal joint portion.
The present invention attempts to solve the problem.

When passing the second joint of the finger of the hand, in order to increase the inner diameter, the part that protrudes outward from the circular part of the ring gauge is turned sideways when viewed from the back of the hand, making it easier to pass through the wide finger part. , After passing through the second joint, rotate the proximal joint so that the outwardly protruding portion comes to the back side of the hand or the palm side so that it does not loosen at the circular part of the ring gauge. A part smaller than half of the circumference of the circular ring gauge protrudes outward so that it can be securely attached.

Alternatively, a circular part smaller than a semi-circumference may be cut out or substantially cut out.
Alternatively, a portion smaller than the semi-circumference of a circular part may be cut out, and both ends of the cut-out portion may be slightly opened. That is, the shape obtained by cutting a portion smaller than the semi-circumference of a circle, or the shape in which the end portion is opened slightly may be substantially the same shape. Or it may be good to close the end a little,

In the case of a shape with a part of the circumference cut off or a shape with both ends slightly open as described above, it is necessary to pay attention to the thickness and material selection so as not to deform when fitting the finger to determine the optimum size. good.
In each case, a set of ring gauges of various sizes (numbers) is used.

Moreover, it is preferable that the inner diameter of the circular portion, including the portion that protrudes outward, is 1.5 to 2.0 mm larger than the inner diameter of the circular portion.

As described above, it is known that the proximal joint width of the second finger joint viewed from the back side of the hand is greater than the joint thickness near the same position viewed from the side of the hand.
Therefore, when passing the second joint of the finger, a projecting part is provided to enlarge a part of the inner diameter of the ring gauge so that it is on the side of the finger so that it can be easily passed, and after passing it through, the proximal joint is passed. When attaching a ring gauge to the part of the ring, generally rotate the ring about 90 degrees so that the overhanging part comes to the back of the hand or the palm side, so that the overhanging part of the ring The non-circular part can be firmly attached to the base part without loosening. That way, you can choose the ring of optimal size.

The same object as described above can also be achieved by cutting a portion smaller than the semi-circumference of the circular portion instead of providing the projecting portion.
The same is true for the above cut shape with both ends slightly open. This makes it easier to pass through the second joint. In some cases, it may be possible to slightly close both ends of the cut shape.
And since a plurality of ring gauges of various sizes are paired together, it is possible to identify the optimum size ring.

Since the overhanging portion is smaller than half of the circumference, the area other than the overhanging portion is larger than half of the circumference, so that it can be firmly attached to the proximal joint portion.
This is the same even when the circular ring is partially cut off as described above.

In order to make it easier to pass the ring through the wide second joint of the finger, it is not necessary to provide a special mechanism for the ring, and only a projecting part is provided in a part of the circular part to increase the inner diameter of a part, or The object can be achieved very simply by forming a shape in which a part of the circular portion is cut off or a shape in which the ends are slightly opened or closed as described above.

The width of the proximal joint of the 2nd joint of the 4th finger seen from the back side of the hand is about 1.0 mm larger than the proximal joint thickness of the 2nd joint of the 4th finger seen from the side of the hand. There is research data that will be described later that it is an average, and considering the variation due to people and a slight margin, the inner diameter of the ring including the overhang is 1.5 than the inner diameter of the circular part not including the overhang. By enlarging it by about 2.0 mm, it is possible to achieve the purpose while maintaining a balance with the size of the circular portion without making the projecting portion unnecessarily large.
In addition, in the case of a ring gauge having a shape in which a part of a circle is cut off, or in which the shape is substantially the same, the object can be achieved with a simpler form.

When the ring gauge is to be removed, it can be easily removed by turning the protruding portion with a large inner diameter or the cut portion sideways and passing it through the second joint in the same manner as when fitting.
