However, it is difficult to implement the invention or to enter the market due to structural complexity, structural change of footwear, and cost increase.

The shoelace can be easily pulled outward at one end or both ends of the shoelace for the troubles of untangling and loosening the shoelace, inconvenience of loosening the shoelace,

The present invention solves the above-mentioned problem by a simple and functional clipping structure in which the shoelace release operation portion is folded by the thumb or index finger to release the shoelace fastening,

We have invented and proposed a shoelace clip which can be applied to a variety of shoes such as sneakers, shoes, casual shoes, military shoes, work shoes, hiking boots, .

In order to solve the above problems,

Two or more shoelace string insertion holes arranged side by side so that the distal ends of the shoelace strings are successively inserted and piled up in a ring shape and a pair of shoelace insertion holes provided on the movement path of the shoelace string inserted into the shoelace insertion hole when the end portion of the shoelace string is pulled An inverted displacement restricting jaw; A shoelace clip having a shoelace, a shoelace clip, and a shoelace clip, the shoelace clip being disengaged from the shoelace when the shoelace is pulled by a thumb or index finger.

In other words, the structure is such that the force balance and the releasing force are released by the mutual action reaction force and the frictional force between the tension of the shoelace and the inverse displacement prevention jaw, and the shoelace is pulled out by pulling one end or both ends of the shoelace, So that the shoelace unfastening operation portion is pulled upward or pulled out to release the shoelace fastening.

Referring to FIG. 5, a shoelace clip having a shoelace insertion hole, an inverted displacement preventing jaw, and a disengaging operation portion is provided on one side and a structure for fixing and attaching the other end side to the shoe body.

That is, the opposite side of the shoelace clip may be fixed to the shoe by various methods such as sewing using a band, re-betting, ultrasonic welding, integral member, and the like, Or a saw tooth structure.

The post-processing of the remaining shoelace may be carried out by using one or more secondary shoelace insertion holes 201 (see Fig. 2) as well as the method shown in 57d, 57e, 57f, 57g, 57h, 57i, , 202a, 202b, 203a, and 203b may be addressed and arranged as shown in 205 and 206 in FIG.

2A, slit-shaped openings 216 and 217 are provided on the side surfaces of the secondary shoelace insertion holes 215 and 217, so that the shoelace is inserted into the middle portion of the shoelace, As shown in Fig.

In addition, this shoelace clip can be fixed and attached to shoes in various ways. That is, it can be fixed and attached to the shoe body by various methods such as sewing, riveting, ultrasonic welding, and means for being integrally provided to a member constituting the shoe.

In addition, when the shoe clip clips are separated from the central portion of the shoelace clip in the case of climbing or mountain climbing, the convenience at the time of detaching and removing the shoe is improved. Preferably, the shoelace clip has a one-touch structure using the elasticity of the member, and the central portion of the shoelace clip can be configured to facilitate separation and fastening of the left and right sides thereof.

The shoelace clip is preferably provided with a shoelace guide jaw such that when the shoelace is close to a circular shape, the shoelace is restrained and guided so that the flow of the shoelace is restrained and guided.

In addition, the shoelace clip is formed of the same material and one piece.

That is, a simple structure composed of a uni-body leads to economic efficiency and productivity enhancement.

In addition, the shoelace clip is configured such that two or more shoelaces having different orientations can be inserted into the shoelace insertion holes so that the shoelace strap can be fastened in different directions (for example, around the foot and ankle) And may be configured to have different directions for easy release.

6, the shoelace clip is configured in the form of a lever having one end fixed in the fore-and-aft direction at an upper portion between the shoelace insertion holes made of a single shoelace;

One side may serve as the unfastening operation part and the other side may be fixed, bending-elastic flow, or hinge.

In this case, a single material or a one piece type is preferable, but it may be composed of two or three parts in order to improve design and operability.

The shoelace can be easily tied to one end or both ends of the shoelace by tilting the shoelace without the inconvenience of tie up the shoelace,

The shoelace unfastening operation portion is folded rearward by the thumb or index finger to release the shoelace fastening. This has the effect of improving convenience and aesthetic appearance at a low cost without changing the structure of the existing shoe.
