Combination assembly of string and adjusting and fastening device

Abstract

A combination assembly includes a string and an adjusting and fastening device. The adjusting and fastening device is a hollow cube. The cube includes two lateral holes and a bottom formed respectively at two lateral sides thereof and a bottom side thereof for communication with inside space thereof and outside. The string is inserted through the lateral and bottom holes to be combined with the cube, having two ends exposed outside the bottom hole. While applied to a shoelace or a chinstrap or other condition requiring tightening/loosening, the combination assembly are good at length adjustment, fixture, and appearance of the string as well as convenient operation thereof.

1 . A combination assembly of a string and an adjusting and fastening device, wherein said adjusting and fastening device is a hollow cube having two lateral holes and a bottom hole respectively formed at two lateral sides thereof and a bottom side thereof for communication between inside space and outside, said string running through said bottom and lateral holes to have two ends exposed outside said bottom hole.  
   
   
       2 . The combination assembly as defined in  claim 1 , wherein said string is provided with a midsection fixed inside said adjusting and fastening device.  
   
   
       3 . The combination assembly as defined in  claim 2 , wherein said midsection of said string is adhesively fixed inside said adjusting and fastening device.  
   
   
       4 . The combination assembly as defined in  claim 1 , wherein said string includes a plurality of retaining portions formed at a predetermined position outside said adjusting and fastening device for preventing said string from pulling into said lateral holes.  
   
   
       5 . The combination assembly as defined in  claim 4 , wherein said retaining portions are formed by heating and hardening parts of said string.  
   
   
       6 . The combination assembly as defined in  claim 4 , wherein each of said retaining portions is formed by a jig clamping said string.  
   
   
       7 . The combination assembly as defined in  claim 1  further comprising a cram plate mounted inside said adjusting and fastening device for partitioning off said two lateral holes into two sections for oppressing said string running under said cram plate.
