Structure of fastener

Abstract

A structure of a fastener is used in an article, such as a garment, a bag, and a shoe and includes a fastener. The fastener has a surface in which at least one hollow portion is formed. The hollow portion has a corner in which a narrow slot that is in communication with the hollow portion is formed. A string is received through the hollow portion and is, after subjected to length adjustment, pressed into the narrow slot so that narrow slot securely clamps the string. As such, the drawbacks and shortcomings of a conventionally used string buckle, such as structural instability, including slipping, vibrating, skewing, and loosening, being difficult to assemble, and having a high manufacturing cost, can be overcome. The fastener may additionally function as a rivet to be mounted to an article, such as a garment, a bag, and a shoe.

I claim: 
     
         1 . A structure of a fastener, comprising a fastener, the fastener having a surface in which at least one hollow portion is formed, the hollow portion having at least one corner in which a narrow slot in communication with the hollow portion is formed, whereby the narrow slot selectively receive and securely clamp a string therein. 
     
     
         2 . The structure of a fastener according to  claim 1 , wherein the fastener has a bottom on which a fixing ring is formed to project therefrom for being combinable with a bottom fixing ring to be riveted to an article, such as a garment, a bag, or a shoe. 
     
     
         3 . The structure of a fastener according to  claim 1 , wherein the hollow portion has a contour showing a pattern of a trademark. 
     
     
         4 . The structure of a fastener according to  claim 2 , wherein the hollow portion has a contour showing a pattern of a trademark. 
     
     
         5 . The structure of a fastener according to  claim 1 , wherein a non-hollowed portion has a portion having a contour showing a pattern of a trademark. 
     
     
         6 . The structure of a fastener according to  claim 2 , wherein a non-hollowed portion has a portion having a contour showing a pattern of a trademark. 
     
     
         7 . The structure of a fastener according to  claim 1 , wherein the surface of the fastener in which the hollow portion is formed is a front surface of the fastener that is easily visible. 
     
     
         8 . The structure of a fastener according to  claim 2 , wherein the surface of the fastener in which the hollow portion is formed is a front surface of the fastener that is easily visible. 
     
     
         9 . The structure of a fastener according to  claim 1 , wherein the surface of the fastener in which the hollow portion is formed is a side surface of the fastener that is easily visible. 
     
     
         10 . The structure of a fastener according to  claim 2 , wherein the surface of the fastener in which the hollow portion is formed is a side surface of the fastener that is easily visible.
