Waist belt structured backpack

Abstract

The present invention relates to a backpack which is worn about the waist of a user, and it provides a backpack for preventing inconvenience in walking caused by sagging of a backpack due to articles therein by employing a pair of pulling means which simultaneously provide pulling power upward and crosswise on both sides of a lower part of the backpack such that the lower part of the backpack can be adhered to the waist more strongly.

What is claimed is:  
     
         1 . A waist belt structured backpack comprising: 
 a compartment which carries articles ( 1 );    a waist belt ( 3 ) having a buckle ( 2 ) which is united with both side ends of said compartment; and    an upper side pulling strap ( 4 ) connected through a buckle ( 5 ) which pulls an upper side of said compartment ( 1 ) toward a waist side, wherein said waist belt structured backpack is constructed by combining: 
 an upward-pulling member ( 6 ) and a transverse-pulling member ( 7 ) which are attached to a lower end of a side surface of said compartment ( 1 );  
 a joint strap ( 8 ) which is united with end parts of said upward-pulling member ( 6 ) and transverse-pulling member ( 7 ); and  
 a lower side pulling strap ( 10 ) capable of adjusting a degree of tension, of which one end is affixed to said waist belt ( 3 ) and another end is inserted into a strap-fastening element ( 9 ) of a joint strap ( 8 ).
