About.

Shoes are, in a dictionary sense, collectively referred to as objects worn to protect the feet when standing or walking on the ground, and are classified in various ways according to their use, but most shoes are shoelaces designed to fit the feet of each individual worn. Is equipped.

Specifically, conventional shoes have an upper that is formed in a shape that wraps the wearer's feet and ankles at the top of the shoe, and a midsole that is formed on the lower side of the upper and absorbs the impact applied by the wearer's walking ( Midsol) and an outsole that is attached to the bottom of the midsole to contact the ground and prevents slipping and enables stable grounding.The upper skin is covered with a tongue that protects and prevents the instep from being pulled. In the front side of the tongue, eyelet stay, which is a reinforcing material in which a lace hole is formed, is provided, and a shoelace for adjusting the shoe to fit the foot is fastened to the lace hole.

Of course, the shoe should be selected in an appropriate size so as not to be peeled off during walking, but since it is standardized and manufactured to a specific length and width by a uniform mass production method, it is difficult for the foot width of the ready-made shoe to accurately match the foot width of the wearer.

Therefore, the wearer should wear shoes to enable safe and comfortable walking, and then properly pull and tighten the shoelaces to ensure close contact between his or her feet and shoes. After pulling and tightening the shoelaces by hand, a knot should be tied and fixed.

However, in order to pull the shoelace in line with the wearer's feet, a certain tension must be applied to the shoelace, and tying the knot on the shoelace requires a relatively delicate work, so it is suitable for the elderly, children, or people with disabilities with hand movements. There is a problem that it gives discomfort.

In order to solve this problem, Korean Utility Model No. 20-0158943 is a shoelace tightening device that can easily and quickly put on and take off shoes without loosening the knot of the shoelace by gently pushing and pulling the rotation lever of the tightening device. Although the technology related to the shoe attached with has been known, the tightening of the shoelace is possible only within the rotation distance of the rotating lever, so the tightening length is short and there is a limitation.
