Lace buckle

Abstract

A structure of a lace buckle is disclosed. The lace buckle comprises a case having a pair of projected blocks at a base., an upper lid, attached to one slide of the case through and attachment part, which can be flipped through 180° to engageably coupling onto the case, wherein two oblique elastic slip lock arms extend vertically from a inner surface from a central region of the upper lid, projecting inwardly into the case. The two elastic slip lock arms will resiliently press against a lace from the top, while the two projected blocks of the case press against the lace from the bottom side, thus the lace is prevented from dislodging from the case, and remain secured in position. Thus the two ends of the lace can be secured in between two elastic slip lock arms of the upper lid and the two projected blocks of the case.

What the claimed is:  
     
         1 . A lace buckle for shoes, bags, and garments, for securing a lace, comprising: 
 a hollow case, having an open top, a side hole on two side wall of the case,    wherein said two side wall are located opposite to each other; 
 two distal ends of a lace inserted into two side holes of the case; and  
 an upper lid, integrally attached to one side of the open top, comprising two oblique elastic slip lock arms extending vertically from a inner surface of the upper lid, wherein said elastic slip lock arms face each other, and face a central vertical plane of the case, flipped through 180° to engageably couple with the case through a coupling means, wherein each of said elastic slip lock arms presses resiliently against each of said lace from a top side for securing said lace in position.  
   
     
     
         2 . The lace buckle according to  claim 1 , wherein the case further comprises at least two projected blocks projecting from a bottom inner side, wherein said projected blocks are positioned alternate to said elastic slip lock arms in conjunction with said elastic slip lock arms secure the lace.  
     
     
         3 . The lace buckle according to  claim 1 , wherein each distal part of said two elastic slip lock arms further comprises a gear-like structure, preventing said lace from being slipped off or pulled out of the case.  
     
     
         4 . The lace buckle according to  claim 1 , wherein the shape of said gear-like structure of each of said elastic slip lock arms is a thorny-wheel shape.  
     
     
         5 . The lace buckle according to  claim 1 , wherein the upper lid comprises a plurality of slip lock elements extending vertically from along a perimeter of the upper lid on a side, and in a central region of each slip lock element comprises a slot for engaging with case.  
     
     
         6 . The lace buckle according to  claim 5 , wherein a hook is disposed on the vertical side wall of the case at a position corresponding to each of said slip lock element of the upper lid, for engageably coupling with the slip lock elements of the upper lid.  
     
     
         7 . The lace buckle according to  claim 1 , wherein the case further comprises a U-shaped element disposed on a outer surface of the case for securing the case in position.  
     
     
         8 . The lace buckle according to  claim 7 , wherein U-shaped element is secured to a surface of a substrate through knitted belt.
