Slip-proof shoelace

Abstract

A slip-proof shoelace being characterized in that: a slip-proof member with a larger coefficient of friction (such as made of silicone, rubber or chemical plastic weaving fiber) is provided on a suitable length extending from each of two ends toward the other end of the shoelace. The slip-proof member can be an elastic sleeve with a smooth surface or a plurality of annular ribs, helical ribs or granules, extending from an end toward the other end of the shoelace, so that the shoelace forms an engaging action at the tying up area, and by the feature of having a larger coefficient of friction, the shoelace can be prevented from loosening and dropping.

1 . A slip-proof shoelace, wherein said shoelace with a large coefficient of friction member on a length extending from an end rearward of said shoelace.  
   
   
       2 . The slip-proof shoelace as claimed in  claim 1 , wherein said slip-proof member is made of silicone.  
   
   
       3 . The slip-proof shoelace as claimed in  claim 1 , wherein said slip-proof member is made of rubber.  
   
   
       4 . The slip-proof shoelace as claimed in  claim 1 , wherein said slip-proof member is made of chemical plastic weaving fiber.  
   
   
       5 . The slip-proof shoelace as claimed in  claim 1 , wherein said slip-proof member is an elastic sleeve with a smooth surface.  
   
   
       6 . The slip-proof shoelace as claimed in  claim 1 , wherein said slip-proof member has a plurality of annular ribs extending from an end toward the other end of said shoelace.  
   
   
       7 . The slip-proof shoelace as claimed in  claim 1 , wherein said slip-proof member has a plurality of helical ribs extending from an end toward the other end of said shoelace.  
   
   
       8 . The slip-proof shoelace as claimed in  claim 1 , wherein said slip-proof member has a plurality of granules extending from an end toward the other end of said shoelace.
