Abstract

A portable accordion file organizer including rectangular front and back panels, accordion walls connecting opposite sides and the bottom of the front and back panels, and N sequential divider panels P n secured to the accordion walls between the front and back panels. Each divider panel has a height greater than the height of the divider panel in front of it and less than the height of the divider panel behind it. The divider panels also each have a cutout section in its top edge wherein the cutout sections of adjacent divider panels are laterally spaced from one another on alternating sides of the center of the divider panel, and have a height which is substantially at least the difference in the height of adjacent divider panels.

1 . A portable accordion file organizer, comprising: 
 a generally rectangular front panel;    a generally rectangular back panel;    accordion walls connecting opposite sides and the bottom of said front and back panels;    N sequential divider panels P n  secured to said accordion walls between said front and back panels;    wherein 
 each divider panel has a height greater than the height of the divider panel in front of it and less than the height of the divider panel behind it, and  
 said divider panels each have a cutout section in its top edge wherein said cutout sections of adjacent divider panels are laterally spaced from one another.  
   
   
   
       2 . The accordion file organizer of  claim 1 , wherein said cutout sections have a height which is substantially at least the difference in the height of adjacent divider panels.  
   
   
       3 . The accordion file organizer of  claim 1 , wherein said divider panels are secured to said accordion walls at substantially equal spacing.  
   
   
       4 . The accordion file organizer of  claim 1 , wherein said cutout sections are positioned on alternating sides of the center of the divider panel top edge on alternate of the sequential divider panels.  
   
   
       5 . The accordion file organizer of  claim 1 , further comprising a cover flap secured to the top edge of the back panel.  
   
   
       6 . A portable accordion file organizer, comprising: 
 a generally rectangular front panel;    a generally rectangular back panel;    accordion walls connecting opposite sides and the bottom of said front and back panels;    N sequential divider panels P n  secured to said accordion walls between said 
 front and back panels, wherein  
 n is an integer from 1 to N,  
 divider panel P 1  is the frontmost divider panel,  
 divider panel P N  is the backmost divider panel,  
 each divider panel P n  has a height h n =h+nD; and D>0;  
   wherein each divider panel has a topmost edge which is substantially straight with a notched section having a bottom edge spaced at least about D below said topmost edge.    
   
   
       7 . The accordion file organizer of  claim 6 , wherein said divider panels are secured to said accordion walls at substantially equal spacing.  
   
   
       8 . The accordion file organizer of  claim 6 , wherein said front panel has a height H F , where h>H F .  
   
   
       9 . The accordion file organizer of  claim 6 , wherein said notched sections are positioned on alternating sides of the center of the divider panel topmost edge on alternate of the sequential divider panels.  
   
   
       10 . The accordion file organizer of  claim 6 , further comprising a cover flap secured to the top edge of the back panel.
