Description

  The present invention relates to a shoelace winding device, and more particularly to a shoelace winding device that securely tightens a shoelace by a rotation method.

  Conventionally, many shoelace winding devices for facilitating the work of tightening shoelaces have been proposed.

  This type of conventional shoelace winding device includes, for example, a shoelace tying device (see, for example, Patent Document 1) in which a shoelace is clamped by a pawl and the shoelace is tied by a shoelace tying device. There is a shoe with a winding device having a winding device that winds up a shoelace through one lace hole (for example, see Patent Document 2).

Taiwan Patent No. I252741 JP 2004-135875 A

However, the conventional technique described in Patent Document 1 has the following three drawbacks.
First of all, when a user ties shoelaces, if they cannot pull up the two shoelaces with one hand and push down the shoelace tying device with the other hand, they cannot tie the shoelaces, It took time and effort. Therefore, it has been difficult for infants or persons with intellectual disabilities to tie shoelaces firmly.

  Second, because the end of the shoelace is not fixed in the shoelace tying device, the shoelace may come off the shoelace tying device when the shoelace is loosened. It took time and effort to get it through again.

  Thirdly, the shoelace is pinched by the pawl, but there is a drawback that the surface of the shoelace is damaged and the life of the shoelace is shortened.

  Moreover, since the conventional technology described in Patent Document 2 is configured to wind up two shoelaces from one direction by a winding device, the winding force is concentrated at one location of the winding device. It is difficult to wind the shoelaces smoothly, and it is difficult to securely tighten the shoelaces.

  Therefore, the present invention has been made in view of the above-mentioned problems, and the shoelace is reliably secured by a rotation method in which two shoelaces are wound using two string holes arranged on an extension line orthogonal to the rotation axis. An object of the present invention is to provide a shoelace winding device that can be tightened or loosened.

  In order to achieve the above-described object, a shoelace winding device of the present invention is a seat body having two string holes that communicate with the storage space and the inside and outside of the storage space and that are disposed on an extended line perpendicular to the rotation axis. A winding body that is disposed in the storage space, rotates around a central axis as the rotation axis, and winds or loosens the shoelace inserted from the lace hole around the winding portion, and the winding body On the same central axis as each other, and the opening has a receiving hole for mounting the locking block on the wall surface, and the locking block has a gear and receives the action of the elastic ring.
