Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for automatically tying and separating a shoelace knot using a magnet,

The present invention relates to a shoelace knot automatic fastening and separating apparatus capable of automatically locking or unlocking a shoelace knot using a magnet, and more particularly, to a shoelace knot automatic fastening and separating apparatus that can easily hold a shoelace knot by using a pair of shoelace fasteners So that the shoes can be easily worn or taken off without manually tying or loosening the shoelace knot every time the shoe is worn. Also, the shoelace knot can be completely worn The present invention relates to a shoelace knot automatic fastening and separating apparatus using a magnet that enables a user to organize a shoelace knot.

In general, in the case of a sneaker or a shoe equipped with a shoelace, in order to wear or remove the shoe, a knot of a shoelace is knotted and a shoelace knot is worn to prevent the shoe from peeling off the wearer's foot after wearing It is safe and convenient. If the shoes are worn or walked without tie the knot of the shoelace, the shoe may easily peel off from the wearer's foot and the shoelace may be caught on the pedestrian's foot or the surrounding article, causing the pedestrian to fall or interfere with the walking It is possible.

However, since the above-described shoelace must be manually tied or loosened each time the shoe is worn or taken off, the time and effort required for the knot are required, which can lead to a lot of troubles in wearing the shoe, The tie knot is loosened while walking, and the shoelace may easily loosen. On the other hand, when the knot is tied too tightly, the shoelace knot tangles or can not be easily loosened if necessary.

In this regard, Korean Patent Application Laid-Open No. 20-2009-0006724 (published on July 21, 2009, hereinafter abbreviated as "Patent Document 1") describes the troubles of tying a knot by tying a shoe to a foot, There is known a technique relating to a shoelace knot apparatus for solving the problem of hanging out.

According to Patent Document 1, a portion for connecting the shoelace string to the shoelace knotting device and a portion for connecting the pair of shoelace knotting devices to which the shoelace string is connected are divided so that both the cost and the convenience can be satisfied at the same time.

In addition, in the Korean Registration Practice No. 20-0463860 (registered on November 23, 2012, hereinafter abbreviated as "Patent Document 2"), a shoelace string knot which can be more easily fastened and fixed without binding the shoelace string, Techniques relating to fastening devices are known.

According to Patent Document 2, a shoelace fastening member for use in tying strings of various shoes is provided, so that the shoelace can be easily and quickly fixed or loosened by a simple operation, so that it can be used more conveniently and practically.

However, according to the conventional techniques as described above, both the former and the latter are configured to fix or release the shoelace by using teeth or the like, so that the shoelace must be damaged as time goes by or the use becomes frequent In the latter case, since the knot is manually fixed or unlocked by using the sawtooth every time the shoe is worn or taken off, the disadvantage that the shoelace fastening is troublesome still remains there was.
