One may be formed of a magnetic material, and the other may be formed of a material that is attached to the magnet, such as metal.

Therefore, when the sliding part 30 is advanced to the tip of the support part 20, the first holding part 70 and the second holding part 80 are attached through magnetic force, and the sliding part 30 while wearing the shoe 1 ) can be prevented from being returned to the original position by the return unit 50 .

The connection part 40 may be formed in a string shape having a constant length.

The connection part 40 may be fixed in such a way that the central part is wound at least once on the front end of the sliding part 30 .

In this case, a binding hole 30a for fixing the connection part 40 may be formed in the sliding part 30 .

The binding hole 30a may be configured as a pair of two, and may be disposed to be spaced apart from each other on the front side of the sliding part 30 .

After winding while passing the connection part 40 through these binding holes 30a several times, tie a knot and fix it.

Accordingly, the connection part 40 is divided into two parts based on the fixed part.

The first prong 41 of the connecting portion 40 protrudes to the outside through the through hole 12b formed on the left side of the first upper 12 , and the second prong 42 is the right side of the first upper 12 . It protrudes to the outside through the through hole (12b) formed in the.

In addition, the first prong 41 protruding to the outside of the main body 10 is fixed to the left prong of the shoelace 16 located on the left side of the main body 10 , and the second prong 42 is the main body part 10 . It is fixed to the right prong of the shoelace 16 located on the right side of (10).

At this time, the shoelaces 16 are in contact with the outer surface of the first upper 12 in a loose state, respectively.

That is, a portion of the shoelace 16 is maintained in contact with both outer surfaces of the outer surface of the first upper 12 , respectively.

In one example, the shoelace 16 is, as shown in FIG. 9 , the first portion 16a passing through the binding means 12a-1 positioned in the third position and the binding means 12a-2 positioned in the fourth position. ) through the second portion 16b and the third portion 16c penetrating through the binding means 12a-3 located closest to the entrance and exit of the main body portion 10 is a portion of the first upper 12 . A first prong 41 and a second prong 42 are in contact with the outer surface, respectively, on both sides of the first upper 12 at the first portion 16a, the second portion 16b, and the third portion 16c. are jointly fixed

On the other hand, in the shoe 1 according to the exemplary embodiment of the present invention, the outer surface of the first upper 12 is covered by covering the shoelace 16 and the connection part 40 in contact with the outer surface of the first upper 12 as described above. It further includes a finishing part (not shown) fixed to the.

The finishing part may be formed of the same material as the first upper 12 , and various contents such as a logo, a pattern, a picture, etc. for improving the design of the shoe 1 may be printed on the surface.

One side of the return unit 50 is fixed to the stopper 100 or the limiting unit 60 and the other side is coupled to the sliding unit 30 .

The return part 50 may be formed of a material having elasticity, such as a rubber band or a coil spring.

Accordingly, the return unit 50 expands when the sliding unit 30 moves forward to impart a restoring force to the sliding unit 30 .

In this case, the separation operation of the first holding part 70 and the second holding part 80 may be performed by sweeping the sliding part 30 with a toe when the user takes off the shoe 1 .

When the first holding part 70 is spaced apart from the second holding part 80, the return part 50 returns to its original length due to the contraction action, and the sliding part 30 moves backward and is located on the upper surface of the stopper 100. .

A limiting part 60 for limiting the backward distance of the sliding part 30 is coupled to the upper surface of the support part 20 .

The limiting part 60 may be formed in a plate shape.

The limiting part 60 may be formed to cover about 1/2 or more of the total area of the support part 20 .

The limiting part 60 covers the entire fixing hole 24 and only a predetermined area of the sliding part 30 located in the rail groove 21 .

And, the front end of the limiter 60 faces the push piece 31 . Accordingly, the sliding part 30 is stopped when the push piece 31 is caught by the limiting part 60 while moving backward.

The stopper 100 may include a horizontal portion 101 and an inclined portion 102 that is inclined upwardly from one end of the horizontal portion 101 .

The stopper 100 is formed of an elastic material such as metal, plastic, synthetic resin, or the like.

The stopper 100 is disposed below the sliding part 30 on the fixing hole 24 .

When the sliding part 30 is moved backward, the inclined part 102 is pressed downward by the sliding part 30, and when the sliding part 30 is separated by the forward movement, the sliding part 30 is there by an elastic force. elevated to position.

In this case, the front end of the inclined portion 102 supports the rear end of the sliding portion 30, so that even if the return force of the return portion 50 is applied to the sliding portion 30, the sliding portion 30 does not move backward. let it do As a result, it is possible to prevent a phenomenon in which the push piece 31 presses the toes from occurring.

The separation part 110 is for releasing the support force of the inclined part 102 with respect to the support part 20 when the user wants to take off the shoe 1, is formed in a line shape, and is located on the inclined part 102 in the receiving space. is fixed

The separation portion 110 may be formed of the same material as the fishing line, and may be wound and fixed to the inclined portion 102 .

Although not shown in the drawings, a portion of the partition 110 may protrude through the second upper 14 , which is the rear surface of the main body 10 , to the outside.

Although not shown in the drawings, fixing means for fixing the spacer 110 protruding to the outside may be formed on the second upper 14 .

The fixing means may be formed in an approximately 'A'-shaped cross-sectional shape when the shoe 1 is viewed from a plane.

Therefore, it is sufficient to wind the spaced part 110 around the fixing means and fix it.

As another example, the spacer 110 may be implemented such that a portion protrudes through the bottom 11 to the outside.

Even when the spacer 110 passes through the bottom 11 as described above, the above-described fixing means may be formed on the second upper 14 .

In this case, a portion of the spacer 110 may be in contact with the bottom surface of the bottom portion 11 , and a portion may be bent upward to be fixed to the fixing means.

Next, the operation of the shoe according to an embodiment of the present invention and a unique effect appearing in the process will be described.

First, when the user pushes the push piece 31 with the toe while wearing the shoe 1 , the stopper 100 is located above the

The sliding part 30 is advanced, and thus the connection part 40 pulls the shoelace 16 while moving along the sliding part 30 .

That is, the portion of the connecting portion 40 protruding outside the main body 10 and connected to the shoelace 16 enters the receiving space of the main body 10 as much as the moving distance of the sliding unit 30, and the shoelace 16 ) by pulling, the shoelace 16 is tightened.

In addition, when the sliding part 30 is advanced, the return part 50 is expanded, and the inclined part 102 that has been pressed in the downward direction by the sliding part 30 is raised by the elastic force and restored to its original shape. It supports the end of the sliding part 30 , and the first holding part 70 has a second holding part 80 attached thereto so that the sliding part 30 does not move backward by the elastic force of the return part 50 .

And, after wearing the shoes (1), it is enough to fix the separation unit 110 to the fixing means.

On the other hand, if you want to take off the shoe (1), first pull the spaced portion 110 fixed to the fixing means so that the inclined portion 102 is lowered in a downwardly curved form.

In this case, the inclined part 102 and the sliding part 30 are alternated in the up and down directions, and the supporting force of the inclined part 102 with respect to the sliding part 30 is released.

In this state, when the shoe 1 is taken off while pushing the upper surface of the sliding unit 30 in the rear end direction of the support unit 20 with at least one toe, the first holding unit 70 is spaced apart from the second holding unit 80 . The action of the return unit 50 is immediately applied to the sliding unit 30 so that the sliding unit 30 is slid to the original position.

In addition, as the user raises the tongue 13 with the instep of the foot in the process of taking off the shoe 1 , the shoelace 16 located on the tongue 13 also works synergistically, and is connected to the shoelace 16 . The connection part 40 is drawn out a predetermined length from the receiving space.

Due to this, the tightening force of the shoelace 16 with respect to the first upper 12 is released, and as a result, the shoelace 16 is loosened, so that it is possible to easily take off the shoe 1 .

Those of ordinary skill in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential features thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
