Loose-leaf storage box

Abstract

A loose-leaf storage box comprising an upper and a lower housing openable and closable relative to each other and is connected by an elongate connecting piece. The connecting piece has thereon more than two integrally molded hooks perpendicular to the connecting piece and being in the shape of “U” each, one of the two vertical rod portions respectively on two ends of a transverse rod portion of each hook is connected with the connecting piece, while the other of the two vertical rod portions is not connected with the connecting piece to form an open end, the open end is able to be raised with a finger to form a notch for receiving loose-leaf collecting sleeves. An outer surface of the open end of the hook has a bottom bevel surface inclined downwards and inwards, so that holes on the loose-leaf collecting sleeves can be slipped over the hooks smoothly to be hooked and fixed.

1 . A loose-leaf storage box used for receiving loose-leaf collecting sleeves, said storage box comprises: 
 an upper and a lower housing adapted to opening and closing relative to each other;    a connecting piece having two lateral sides connected with inner sides of said upper and said lower housings;    at least two hooks perpendicular to and integrally molded with said connecting piece, said hooks each is formed near a surface of said connecting piece an openable hoop with two ends, one of said ends is integrally connected with said connecting piece, while the other end is not connected with but with its bottom end adjacent to said connecting piece to form an open end;    said loose-leaf collecting sleeves each has holes on one edge thereof at least corresponding by position to said hooks, each of said hooks is adapted to moving about an end thereof integrally connected with said connecting piece, thereby a bottom end of said open end is separated from said connecting piece to form a notch, and loose-leaf collecting sleeves thus are adapted to sliding into said notch to have holes of said loose-leaf collecting sleeves aligned with said hook; after releasing said force, a bottom end of said open end restores to a state being adjacent to said connecting piece, thus said loose-leaf collecting sleeves are fixed on said hook.    
   
   
       2 . The loose-leaf storage box as claimed in  claim 1 , wherein said hooks each is in the shape of “U”, and has a transverse rod portion, a first vertical rod portion and a second vertical rod portion on two ends of said transverse rod portion; said first vertical rod portion is integrally connected with and extending from said connecting piece to connect one of said two ends of said transverse rod portion; while said second vertical rod portion is extended down from the other end of said transverse rod portion, and has a bottom end which is adjacent to said connecting piece to form an open end; 
 each of said hooks is adapted to moving about a junction between said first vertical rod portion of said hook and said connecting piece when said hook is exerted with a raising force, thereby a bottom end of said second vertical rod portion is separated from said connecting piece to form a notch, and said loose-leaf collecting sleeves thus are adapted to moving to slide into said notch to have said holes of said loose-leaf collecting sleeves aligned with said second vertical rod portion; after releasing said force, said bottom end of said second vertical rod portion restores to said state being adjacent to said connecting piece, thus said loose-leaf collecting sleeves are fixed on said hooks.    
   
   
       3 . The loose-leaf storage box as claimed in  claim 2 , wherein an outer surface of said second vertical rod portion has a bottom bevel surface inclined downwards and inwards.  
   
   
       4 . The loose-leaf storage box as claimed in  claim 2 , wherein 
 said outer surface of said second vertical rod portion is adapted to being touched and raised with a finger, so that said bottom end of said second vertical rod portion of said hook is separated from said connecting piece to form said notch.    
   
   
       5 . The loose-leaf storage box as claimed in  claim 1 , wherein said hooks each is in the shape of a circular ring.
