Description

CROSS-REFERENCE TO RELATED APPLICATION

This Application is a Section 371 National Stage Application of International Application No. PCT/KR2014/006984, filed on Jul. 30, 2014, the contents of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present invention relates to a footwear fastening structure. More particularly, the present invention relates to a footwear fastening structure which is used in replacement of a shoelace of shoes or footwear, eliminates the necessity for tying or untying a shoelace, and prevents the shoelace from being loosened, thereby improving an convenience in use.

BACKGROUND ART

In general, a shoelace member mostly has a circular or elliptical cross-section and is woven in a straight line.
Such a conventional shoelace member entails a problem in that after the shoelace member is tied or knotted, it is easily untied or loosened of itself due to shaking caused by motion of a user's ankle while he or she is walking.
Numerous prior arts have been proposed in an attempt to prevent the shoelace member from being easily untied. As one example, Korean Utility Model Laid-Open Publication No. 96-19744 (hereinafter, referred to as “prior art 1”) discloses a shoelace member that is not easily untied.
The prior art 1, however, encounters a problem in that the shoelace member has a plurality of resin projections attached to the top and bottom surfaces thereof at its entirety, thus making it difficult to manufacture and increasing the manufacturing cost.
Besides the above prior art 1, various prior arts have been proposed in an attempt to prevent the shoelace member from being easily loosened. For example, Korean Utility Model Registration No. 0451160 (discloses (hereinafter, referred to as “prior art 2”) discloses a device for preventing a shoelace knot from being untied.
The prior art 2 will be described hereinafter. The device of the prior art 2 includes: a shoelace knot loosing-preventive member 21 that is securely fixed at both ends to the top surface of a shoe tongue 11 of a shoe or footwear in the longitudinal direction of the shoe so as to allow a knot of the shoelace tightened on the shoe to be brought into close contact with the shoe tongue to prevent the shoelace knot from being untied due to motion of a user's ankle; a shoelace fixing member 22 fixed to the top surface of the shoe tongue, the shoelace fixing member having an insertion groove for allowing the shoelace knot loosing-preventive member to be inserted thereto in a transverse direction and an elastic member for securely fixing the shoelace knot loosing-preventive member inserted into the insertion groove using an elastic force; and a button member 23 coupled to the upper portion of the shoelace fixing member so that when the button member is pressed downwardly, the elastic member is pressurized to cause the shoelace knot loosing-preventive member to be released from its fixed state.
However, the prior arts 1 and 2 still involve problems in that since a shoelace loosing-preventive structure for tying the shoelace member is complicated, the number of the manufacturing processes is increased, and in that it is required that the shoelace should be tieably engaged in all the shoelace tying holes or eyelets and then be lastly knotted, thus making the knotting process inconvenient.

Also, the following terms particularly defined in consideration of the configuration and function of the present invention may vary according to an intention of a user or an operator or according to custom. Therefore, definition of such terms should be made based on overall contents of the specification.

First Embodiment

FIG. 1 is a perspective view showing a footwear fastening structure according to an embodiment of the present invention, FIG. 2 is a view showing an example of the stepwise application of a footwear fastening structure according to an embodiment of the present invention to a shoe, FIG. 3 is a perspective view showing a shoe to which a footwear fastening structure according to an embodiment of the present invention is applied, and FIG. 4 is a top plan view showing a footwear fastening structure according to another embodiment of the present invention.
As shown in FIGS. 1 to 4, a footwear fastening structure A1 according to the present invention is configured such that it is tieably engaged in shoelace tying holes or eyelets 110 of a shoe or a sports shoe 100 so as to fasten the shoe or the sports shoe tightly on a user's foot when he or she wears the shoe. The footwear fastening structure includes a main body 2 having a predetermined length and flexibility, the main body being formed in a wide flat plate shape, and a pair of opposed stopper units formed at both ends of the main body 2, respectively, so as to be fixedly inserted into the shoelace tying holes 110 in such a manner as to pass through the shoelace tying holes and then to be hooked in the shoelace tying holes.
The main body 2 is formed in a wide flat plate shape having a predetermined length using a material harmless to the human body and having flexibility.
In addition, a distance between the shoelace tying holes 110 formed at both sides of an upper of the shoe is typically determined substantially uniformly and is increased gradually as it goes toward the ankle from the top side of the foot. Thus, in view of this, the main body 2 is manufactured uniformly of various kinds, from a short one to a long one.
The shoelace tying holes 110 are formed by perforating both sides of an upper of a shoe symmetrically so that a shoelace can be tieably engaged in the shoelace tying holes. Rivets may be fixedly engaged h the shoelace tying holes 110 to improve durability.
A pair of opposed stopper units 4 is formed at both ends of the main body 2, and can be made of a material the same as that of the main body 2 or a material having, a hardness higher than that of the main body 2.
Thus, the main body 2 is made of rubber or silicone having flexibility, but the stopper units 4 are made of a rigid synthetic resin material. As such, the footwear fastening structure is formed by subjecting dissimilar materials to a composite molding process.
The stopper unit 4 is formed in any one shape selected from among a circular shape, an elliptical shape, a spade shape, a heart shape, and an arrow shape.
Preferably, the stopper unit 4 is formed in an arrow shape which is gradually tapered toward a distal end thereof to form a sharpened distal end, and has projections 42 formed at both side ends thereof in such a manner that a distance between the both projections is larger than the inner diameter of each shoelace tying hole 110 as shown in the drawings.
Preferably, a narrow portion 22 is formed at the connection part between the main body 2 and each of the stopper units 4. In this case, the narrow portion has a width that is smaller than that of the main body 2 and is equal to or smaller than the inner diameter of each shoelace tying hole 110.
Thus, the stopper unit 4 passes through the shoelace tying hole 110, and then is hookedly fit into the inner circumferential surface of the shoelace tying hole 110.
A withdrawing tap 6 is formed at the sharpened front end of each of the stopper units 4 so as to have a predetermined length so that a user easily pulls the withdrawing tap outwardly with his or her fingers.
In other words, when the user pulls the withdrawing tap 6 outwardly while gripping the withdrawing tap with his or her fingers, the stopper unit 4 can rapidly pass through the shoelace tying hole 110.
After the stopper unit 4 passes through the shoelace tying hole 110, the withdrawing tap 6 is removed by cutting. In this case, the withdrawing tap 6 is cut out by a knife or scissors.
In addition, a cutting line (not shown) may be formed at the connecting part between the withdrawing tap 6 and the stopper unit 4. The cutting line is formed by perforating the connection part between the withdrawing tap 6 and the stopper unit 4 in a dotted line shape so that the cutting line is easily cut out. Therefore, when the withdrawing tap 6 is forcibly pulled from one side to the other side, the cutting line is cut out so that the withdrawing tap can be easily removed even without a separate cutting tool.
A use example of the footwear fastening structure according to an embodiment of the present invention as constructed above will be described hereinafter.
First, a user passes the withdrawing tap 6 of the stopper unit 4 through the shoelace tying hole 110 and then forcibly pulls the withdrawing tap 6 outwardly while gripping it with his or her fingers so as to allow the stopper unit to completely pass through the shoelace tying hole 110 so that the narrow portion 22 is hookedly fit into the shoelace tying hole 110.
The stopper unit 4 at an opposite side is also caused to pass through and to be engaged in the shoelace tying hole 110 in the above-mentioned manner.
Then, the withdrawing tap 6 is cut out to be removed.
When the stopper unit 4 passes through the shoelace tying hole 110, the projections 42 formed at both side ends of the stopper unit 4 is hooked on the outer circumferential edge of the shoelace tying hole 110. Thus, although a force pulling the main body 2 outwardly (i.e., a force with which the top side of the foot pushes the main body 2 when a user is walking or running) is exerted onto the stopper unit 4, the stopper units 4 at both sides of the upper of the shoe is maintained in a fixed state so that the stopper units 4 do not easily escape from the shoelace tying holes 110 but can be stably maintained in a tied state.

Second Embodiment

Meanwhile, FIG. 5 is a perspective view showing a footwear fastening structure according to another embodiment of the present invention, and FIG. 6 is a partial top plan view showing a footwear fastening structure according to another embodiment of the present invention.

The footwear fastening structure includes: a main body 2 b having a predetermined length and flexibility, the main body being formed in a wide flat plate shape, and a pair of opposed stopper units 4 b formed at both ends of the main body 2 b, respectively, so as to be fixedly inserted into the shoelace tying holes 110 in such a manner as to pass through the shoelace tying holes 110 and then to be hooked in the shoelace tying holes.
Each of the stopper units 5 b is formed in an arc shape at a front portion thereof, and is gradually tapered toward both side ends thereof to form sharpened hooks 43 b at both side ends thereof, and a distance between the sharpened hooks 43 b is larger than a width of the main body 2 b.
A narrow portion 22 b is formed at the connection part between the main body 2 b and each of the stopper units 4 b. In this case, the narrow portion 22 b has a width that is smaller than that of the main body 2 b and is equal to or smaller than the inner diameter of each shoelace tying hole 110.
Herein, a core material (not shown) may be embedded in the connection part between the main body 2 b and the stopper unit 4 b to reinforce the strength of the footwear fastening structure to prevent the connection part from being torn out.
A use example of the footwear fastening structure according to another embodiment of the present invention as constructed above will be described hereinafter.
First, when a user forms the sharpened hooks 43 b at both side ends of the stopper unit 4 in a roll shape by slightly folding the hooks 43 b inwardly, and then passes the roiled hooks 43 b through the shoelace tying hole 110, the narrow portion 22 b is hookedly fit into the shoelace tying hole 110 and the rolled hooks 43 b simultaneously returns to its original state to cause the rolled hooks 43 b to be unfolded so that the hooks 43 b can be hooked in the shoelace tying hole 110 so to be maintained in a hooked state.
