Structure of eyeleted string fastener

Abstract

An eyeleted string fastener includes a button base and a fastener. The button base has a bottom on which a hollow fitting cylinder is formed for riveting and thus attaching to an article, such as clothing, a bag, or a shoe. The fitting cylinder has a top rim that is expanded outward to form a stop ring. The stop ring has an outer circumferential edge from which a circumferential wall extends upward so that the circumferential wall forms therein a receiving compartment to receive the fastener therein. The fastener has a surface having a circumferential rim portion forming a pressing section that is depressible down for coupling to the button base. A hollowed portion is formed inboard and surrounded by the pressing section. The hollowed portion has a side in which a narrowed slot is formed.

I claim: 
     
         1 . An eyeleted string fastener, comprising a button base and a fastener and characterized in that
 the button base has a bottom on which a hollow fitting cylinder is formed, the fitting cylinder having a top rim that is expanded outward to form a stop ring, the stop ring having an outer circumferential edge from which a circumferential wall extends upward so as to form therein a receiving compartment; and   the fastener is receivable in the receiving compartment of the button base and has a surface having a circumferential rim portion forming a pressing section that is depressible down for coupling to the button base, a hollowed portion being formed inboard and surrounded by the pressing section, the hollowed portion having a side in which a narrowed slot is formed so that the narrowed slot is adapted to pinch and fasten a string, wherein the fastener is riveted and thus fixed to the button base by directly pressing down a top edge of the circumferential wall of the button base.   
     
     
         2 . The eyeleted string fastener according to  claim 1 , wherein the narrowed slot of the fastener is formed in communication with the hollowed portion. 
     
     
         3 . The eyeleted string fastener according to  claim 1 , wherein the fastener comprises a projection block formed beside the hollowed portion and the narrowed slot is formed in a side of the projection block that is opposite to the hollowed portion. 
     
     
         4 . An eyeleted string fastener, comprising a button base, a fastener, and a surface frame and characterized in that
 the button base has a bottom on which a hollow fitting cylinder is formed, the fitting cylinder having a top rim that is expanded outward to form a stop ring, the stop ring having an outer circumferential edge from which a circumferential wall extends upward so as to form forms therein a receiving compartment;   the fastener is receivable in the receiving compartment of the button base and has a surface having a circumferential rim portion forming a pressing section that is depressible down for coupling to the button base, a hollowed portion being formed inboard and surrounded by the pressing section, the hollowed portion having a side in which a narrowed slot is formed so that the narrowed slot is adapted to pinch and fasten a string; and   the surface frame is set on and covers the fastener so that a flange of the surface frame engages and presses down the pressing section of the fastener and the surface frame is located inboard the circumferential wall of the button base to be fixed by being riveted and pressed down by a top edge of the circumferential wall.   
     
     
         5 . The eyeleted string fastener according to  claim 4 , wherein the flange of the surface frame presses down the pressing section of the fastener and the surface frame is located outside the circumferential wall of the button base and is fixed by riveting the flange of the surface frame. 
     
     
         6 . The eyeleted string fastener according to  claim 4 , wherein the narrowed slot of the fastener is formed in communication with the hollowed portion. 
     
     
         7 . The eyeleted string fastener according to  claim 4 , wherein the fastener comprises a projection block formed beside the hollowed portion and the narrowed slot is formed in a side of the projection block that is opposite to the hollowed portion.
