Lacing system for shoe

Abstract

A lacing system for a shoe is disclosed. The lacing system for a shoe, according to the present invention, is a lacing system utilized for tying purposes so as to be coupled to string lacing eyelets of a dress shoe or a sneaker such that a shoe is firmly worn on the foot, and the lacing system for a shoe comprises: a body having elasticity; and hook portions which are respectively formed on both end portions of the body, and which are fastened by being inserted into the string coupling holes. Accordingly, the hook portions formed on both ends of the elastic body are coupled by being inserted and hooked into the string lacing eyelets when a dress shoe or a sneaker is worn such that the body is firmly fastened so as to prevent untying.

What is claimed is: 
     
         1 . A footwear fastening structure configured such that it is tieably engaged in shoelace tying holes or eyelets of a shoe or a sports shoe 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 comprising:
 a main body 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, respectively, so as to be fixedly inserted into the shoelace tying holes in such a manner as to pass through the shoelace tying holes and then to be hooked in the shoelace tying holes.   
     
     
         2 . The footwear fastening structure according to  claim 1 , wherein each of the stopper units is made of a material the same as that of the main body or a material having a hardness higher than that of the main body. 
     
     
         3 . The footwear fastening structure according to  claim 1 , wherein each of the stopper units is formed in an arrow shape which is gradually tapered toward a distal end thereof to form a sharpened distal end, and has projections 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. 
     
     
         4 . The footwear fastening structure according to  claim 1 , a narrow portion is formed at the connection part between the main body and each of the stopper units, the narrow portion having a width that is smaller than that of the main body and is equal to or smaller than the inner diameter of each shoelace tying hole. 
     
     
         5 . The footwear fastening structure according to  claim 1 , a withdrawing tap is formed at the sharpened front end of each of the stopper units so as to have a predetermined length, the withdrawing tap being configured to be removed by cutting. 
     
     
         6 . The footwear fastening structure according to  claim 1 , wherein a cutting line is formed at the connecting part between the withdrawing tap and the stopper unit. 
     
     
         7 . The footwear fastening structure according to  claim 1 , wherein each of the stopping units is formed in any one shape selected from among a circular shape, an elliptical shape, a spade shape, and a heart shape. 
     
     
         8 . The footwear fastening structure according to  claim 1 , wherein each of the stopper units is formed in an arc shape at a front portion thereof, and is gradually tapered toward both side ends thereof to form sharpened hooks at both side ends thereof, a distance between the sharpened hooks being larger than a width of the main body. 
     
     
         9 . The footwear fastening structure according to  claim 8 , wherein a narrow portion is formed at the connection part between the main body and each of the stopper units, the narrow portion having a width that is smaller than that of the main body and is equal to or smaller than the inner diameter of each shoelace tying hole.
