Description

[Detailed Description of the Invention] This invention relates to an adjustment tool used to adjust a wrist band body such as a watch band or bracelet to match the thickness of the user's arm.

If a watch band or bracelet is too long, it will be uncomfortable to use, and if it is too short, it will become unwearable. Therefore, it is necessary to cut the watch band or bracelet accurately to the required length, but it is difficult to set the cutting length accurately. It is extremely difficult and requires skill.

This is because not only does each band have different flexibility, but they also include rigid parts like the watch body, so the degree of adhesion to the wrist varies slightly depending on the band, so it is difficult to simply unfold the band. If you only decide the length based on the length, you will not be able to create a band that is comfortable to use.

Up until now, the user had to keep the user waiting, cut the band on the spot, try it on their arm, and check the fit, and then repeat the process, or they could keep the item and wait for the required length. The reality is that we have to cut the parts to the right angle and readjust the parts that are not well-fitted, and it takes a lot of effort and time until we can use them again.

In view of the current situation, this invention enables the length of a watch band, etc. to be adjusted accurately using a tool with a simple structure.The details of the invention will be explained based on an example shown in the drawings as follows.

The main body 1 is a truncated cone with an oval or elliptical cross section, and is usually made of wood material.

The cross-sectional shape of the main body 1 approximates the cross-sectional shape of an arm.
Therefore, the shape may be similar to an ellipse or an ellipse.

A scale 2 is provided on the circumferential surface of the main body 1 along the height direction.

This scale 2 corresponds to the scale 4 of a tape measure body 3 that is separate from the main body 1, and the thickness of the arm measured with the tape measure body 3 is expressed by the thickness of the corresponding scale 2 on the body 1. It looks like this.

The tape measure body 3 is used as a set with the main body 1, and is provided with a stopper 5 and a hole 6 for the hook, imitating a watch band.

In addition to a standard length unit such as cm, a unique length unit may be set and used for the scale 4 of the tape measure body 3.

This device has the above-mentioned structure, and in use, the measuring tape 3 is wrapped around the user's arm and the thickness of the arm is measured while checking the degree of adhesion and feeling of use.

After that, cut the watch band B or bracelet and fit the band body made into a small diameter into the main body 1, and adjust the band body so that the main body 1 is at the position of the scale 2 corresponding to the scale 4 measured with the tape measure body 3. Make small adjustments to the length.

The degree of fit and adhesion of the band body to the main body 1 is extremely low compared to when it is fitted on the arm, so by cutting and adjusting the band body according to the scale 2 of the main body 1, the feeling of use of the band body can be improved. Can be adjusted to the appropriate length.

In this way, according to this invention, if you first measure the thickness of the user's arm with a tape measure, you can adjust the length of the watch band etc. to the appropriate length by simply fitting the watch band etc. to the main body and adjusting it. There is no need to make customers wait for a long time or readjust the length many times as in the past, simplifying adjustment work and improving service to users.

What's more, the tape measure has a hole in the stopper and the hook is very low on the watch band, so by fitting it onto your wrist and securing it with the stopper, you can get the same feeling of use as a watch band. Therefore, the watch band can be adjusted to a length that is extremely comfortable to use.

Furthermore, since the shape of the main body is similar to that of the arm, it is possible to set a length that fits well on the arm from this point of view as well.
