Description

Wristband Having Variable Compression Structure

The present invention relates to a wristband, and more particularly, to a wristband including a variable compression structure capable of changing the degree of support of a wrist according to a user's intention.

In general, a wristband is worn on the wrist to fix the wrist or to protect the wrist when performing an exercise that requires a lot of wrist use or when the wrist is injured.

For this purpose, a conventional wristband is generally composed of a band body having a constant width and surrounding the wrist, and a pair of Velcro tapes respectively attached to both ends of the band body.

Such a conventional wristband is attached to the wrist by pulling and winding the other end while pressing one end of the band body against the joint of the wrist, and then overlapping the Velcro tapes at both ends of the band body.

However, in the conventional wristband, since the band body is placed on the joint of the wrist and pressed, the Velcro tapes at both ends of the band body overlap each other and are worn by pulling the other end, so it is difficult to wear with one hand and is difficult to use. there is

In addition, in the case of a conventional wristband, most of the band main body only serves to simply press the wrist or absorb external shock to some extent when worn.

On the other hand, recently, as interest in human health has increased along with the trend of well-being, interest in exercise such as aerobic, etc., which can be provided with strong power, has increased.

In particular, during aerobic exercise, weights are used on the arms to increase muscle strength and exercise effects by lifting dumbbells or wearing sandbags on the wrists.

However, in the case of aerobics using dumbbells, since the exercise must be performed while holding the dumbbells, the range of motion is limited, or in some cases, side effects such as missing dumbbells resulting in injury or calluses on the palms are caused. .

In addition, when performing aerobics by wearing a sandbag, sweat generated during exercise is not properly absorbed by the sandbag, resulting in considerable inconvenience such as damage to the skin of the wrist.

In order to solve this problem, as shown in FIG. 1, a wristband 10 including a cylindrical band body 11 in which an absorbent bag 15 accommodating a moisture absorbent is partitioned by sewing and an elastic band 21 has been developed

However, the wristband 10 according to the prior art shown in FIG. 1 has a problem in that it cannot change the thickness of the wearer's wrist and the degree of pressure desired by the wearer.

Therefore, there is a need for a technique capable of solving the above-mentioned problems according to the prior art.
