Multiple overlapping method and apparatus of band or shoulder strap

Abstract

Disclosed herein is a multiple overlapping method and apparatus of a band or a shoulder strap by using a length-adjustment buckle and a fixing ring. A length of the band or the shoulder strap can be reduced to one-third or one-fourth of the longest length.

1 . A multiple overlapping method for adjusting a length of a band or a shoulder strap which includes a length-adjustment buckle having a main frame provided with a space and an auxiliary frame fixed to the main frame across the space of the main frame to divide the space into a first coupling space and a second coupling space, fixing rings provided with a space, and a string, comprising the steps of:
 connecting a first end of the string fixedly to one of the fixing rings;   passing a second end of the string through the first coupling space and the second coupling space of the length-adjustment buckle, the string hanging on the auxiliary frame of the length-adjustment buckle;   drawing the second end of the string up to the other fixing ring and passing the second end of the string through the space provided at the other fixing ring;   drawing the second end of the string up to the length-adjustment buckle and passing the second end of the string through the first coupling space and the second coupling space of the length-adjustment buckle, the string hanging in duplicate on the auxiliary frame of the length-adjustment buckle; and   drawing the second end of the string again up to the other fixing ring, passing the second end of the string through the space provided at the other fixing ring, and fixing the second end of the string to another portion of the string which comes into contact with the second end of the string.   
   
   
       2 . The method according to  claim 1 , wherein the second end of the string is fixed to another portion of the string contacting the second end by buttons which are detachably attached to each other. 
   
   
       3 . A multiple overlapping method for adjusting a length of a band or a shoulder strap which includes a length-adjustment buckle having a main frame provided with a space and an auxiliary frame fixed to the main frame across the space of the main frame to divide the space into a first coupling space and a second coupling space, fixing rings provided with a space, and a string, comprising the steps of:
 connecting a first end of the string fixedly to one of the fixing rings;   passing a second end of the string through the first coupling space and the second coupling space of the length-adjustment buckle, the string hanging on the auxiliary frame of the length-adjustment buckle;   drawing the second end of the string up to the other fixing ring and passing the second end of the string through the space provided at the other fixing ring;   drawing the second end of the string up to the length-adjustment buckle and passing the second end of the string through the first coupling space and the second coupling space of the length-adjustment buckle, the string hanging in duplicate on the auxiliary frame of the length-adjustment buckle;   drawing the second end of the string again up to the other fixing ring and passing the second end of the string through the space provided at the other fixing ring; and   drawing the second end of the string again up to the length-adjustment buckle, passing the second end of the string through the first coupling space and the second coupling space of the length-adjustment buckle, the string hanging in triplicate on the auxiliary frame of the length-adjustment buckle, and fixing the second end of the string to another portion of the string which comes into contact with the second end of the string.   
   
   
       4 . The method according to  claim 3 , wherein the second end of the string is fixed to another portion of the string contacting the second end by buttons which are detachably attached to each other. 
   
   
       5 . A multiple overlapping apparatus of a band or a shoulder strap having a string, being characterized in that:
 an end of the string is fixed to another portion of the string contacting the end of the string by buttons which are detachably attached to each other or velcro tapes.
