Length adjustable binding strap

Abstract

A length adjustable binding strap includes a buckle having a threading space. A strap has a coupling part formed on a surface thereof. The strap has a first pull part and a second pull part at two ends thereof. The first pull part is threaded through the threading space of the buckle, and the strap wraps around two ends of the buckle. The coupling parts of the two ends of the strap are connected to each other. A binding space is formed by coiling the strap. The first pull part is pulled to adjust a length of the strap at the two ends of the buckle so as to adjust a size of the binding space.

What is claimed is: 
     
         1 . A length adjustable binding strap, comprising:
 a buckle ( 1 ) having a threading space ( 10 );   a strap ( 2 ) having a coupling part ( 20 ) formed on a surface thereof, the strap ( 2 ) having a first pull part ( 21 ) and a second pull part ( 22 ) at two ends thereof, the first pull part ( 21 ) threaded through the threading space ( 10 ) of the buckle ( 1 ), and the strap ( 2 ) wrapping around two ends of the buckle ( 1 ), the coupling parts ( 20 ) of the two ends of the strap ( 2 ) being connected to each other, a binding space ( 23 ) being formed by coiling the strap ( 2 ), and   wherein the first pull part ( 21 ) is pulled to adjust a length of the strap ( 2 ) at the two ends of the buckle ( 1 ) so as to adjust a size of the binding space ( 23 ).   
     
     
         2 . The length adjustable binding strap as claimed in  claim 1 , wherein the coupling part ( 20 ) is a hook-and-loop fastener. 
     
     
         3 . The length adjustable binding strap as claimed in  claim 1 , wherein the coupling part ( 20 ) is double-sided tape. 
     
     
         4 . The length adjustable binding strap as claimed in  claim 1 , wherein the buckle ( 1 ) includes three transverse bars so as to form a first hole ( 100 ), a second hole ( 101 ), and a third hole ( 102 ), the first, second and third holes ( 100 ,  101 ,  102 ) are located corresponding to the threading space ( 10 ). 
     
     
         5 . The length adjustable binding strap as claimed in  claim 4 , wherein the first pull part ( 21 ) of the strap ( 2 ) is threaded through the first hole ( 100 ) and the second hole ( 101 ) from one side of the buckle ( 1 ), then extended to a certain length before looping back to the buckle ( 1 ), and then passed through the third hole ( 102 ) to emerge from the other side of the buckle ( 1 ), exposing the first pull part ( 21 ) outside the buckle ( 1 ), the movable pulling of the first pull part ( 21 ) is movably pulled to adjust the length of the strap ( 2 ) at the two ends of the buckle ( 1 ), the strap ( 2 ) located close to the first hole ( 100 ) of the buckle ( 1 ) is bent to form a fixed part 
     
     
       ( 24 ) the fixed part ( 24 ) has a fixed hole ( 240 ). 
     
     
         6 . The length adjustable binding strap as claimed in  claim 5 , wherein the fixed part ( 24 ) is connected to a fixed hanging ring ( 3 ). 
     
     
         7 . The length adjustable binding strap as claimed in  claim 5 , wherein the fixed part ( 24 ) is connected to a rotating hanging ring ( 4 ). 
     
     
         8 . The length adjustable binding strap as claimed in  claim 5 , wherein the fixed part ( 24 ) is connected to a handle ( 5 ), the handle ( 5 ) has a non-slip part ( 50 ) on its surface. 
     
     
         9 . The length adjustable binding strap as claimed in  claim 1 , wherein when pulling the first pull part ( 21 ) to make the length of the strap ( 2 ) above the buckle ( 1 ) is longer than the length of the strap ( 2 ) below the buckle ( 1 ), the binding space ( 23 ) formed by the coiled strap ( 2 ) is defined as a first binding space ( 230 ). 
     
     
         10 . The length adjustable binding strap as claimed in  claim 1 , wherein when pulling the first pull part ( 21 ) to make the length of the strap ( 2 ) above the buckle ( 1 ) is the longest, and the length of the strap ( 2 ) below the buckle ( 1 ) is the shortest, the binding space ( 23 ) formed by the coiled strap ( 2 ) is defined as a second binding space ( 231 ), the second binding space ( 231 ) is larger than the first binding space ( 230 ).
