Description

[0001] Automatic shoelace fastener [0002]

The present invention relates to a shoelace automatic tightening device. More particularly, the present invention relates to a shoelace automatic tightening device for tightening or loosening a shoelace string by a user's load.

Generally, when people are wearing shoes, they have tied the knot to the shoelace by hand. The work to tie the knots in this way requires a relatively delicate work, which is disadvantageous for the elderly, children, or persons with handicaps who are uncomfortable with their movements.

In addition, when there is a situation in which shoes must be removed urgently, there is a problem that shoes must be removed by unbending each knot.

In order to solve the above problems, a shoe having a slide fastener attached to the side of a shoe has been invented. However, the manufacturing process is complicated and water is absorbed by the sewing part of the slide fastener and the shoe upper. Is short and it is difficult to replace it at the time of breakage.

In order to solve these problems, a shoe with a shoelace fastening device such as the Korean Utility Model No. 1999-0002342 was invented. The 'shoe with the shoelace tightening device' is provided with a tightening device on the side of the shoe while the shoelace is tightened in advance, and a shoelace is connected to the end of the tightening protrusion which is an element of the tightening device, And the grip portion for tightening and tightening the fastening protrusion is tightened so as to prevent the shoelace string from being loosened by operating the pawl lever.

However, even in the case of such a conventional technique, there is a problem that the gripping state can be released by a phenomenon such as impact or engagement with the outside, so that the fastening state of the shoelace is loosened.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 10-2015-0032516, a shoelace winding reel, was invented. The 'shoelace winding reel' can easily tighten or loosen the shoelace simply by turning the dial by binding the shoe strap to the shoelace winding reel.

However, even in this conventional technique, in order to fasten the shoelace, the shoelace must be adjusted by bending the waist or lifting the leg. This method has a problem that it is difficult to use in the case of an elderly person or a handicapped who can not bend their back or lift their legs.
