Cube white board eraser

Abstract

A method and apparatus for removal of dry ink dust and for conditioning of white boards, which includes a removable and selectively replaceable core that may optionally be treated with cleaning and anti-static compounds. The core may be a foam cube having six surfaces each individually capable of cleaning a whiteboard. The core being removable and reinsertable in a different orientation to provide a superior cleaning surface.

I claim:  
     
         1 . An eraser for cleaning white boards comprising: 
 a core having an exterior; and,    a plurality of substantially identically dimensioned cleaning surfaces that are substantially flat disposed on said exterior of said core.    
     
     
         2 . The eraser of  claim 1  further comprising: 
 a holder having a receiving portion dimensioned to allow selective removal and reinsertion of said core, wherein said holder exposes at least one cleaning surface of said core.  
 
     
     
         3 . The eraser of  claim 1  further comprising: 
 a scrapper.  
 
     
     
         4 . The eraser of  claim 2  further comprising: 
 a collector positioned to accept dust removed by said scrapper.  
 
     
     
         5 . The eraser of  claim 1  wherein the core is selected from the group consisting of foam, cork, felt, wood, plastic, cotton, synthetic fabric and a combination thereof.  
     
     
         6 . The eraser of  claim 4  wherein said core is an open celled foam.  
     
     
         7 . The eraser of  claim 1  wherein said core is a cube capable of having six cleaning surfaces.  
     
     
         8 . The eraser of  claim 1  further comprising: 
 a holding apparatus.  
 
     
     
         9 . The eraser of  claim 6  further comprising: 
 a whiteboard conditioning fluid impregnated into said open celled foam.  
 
     
     
         10 . An eraser for cleaning white boards comprising: 
 a holder having a receiving portion;    a removable core having an exterior dimensioned and selectably positionable to fit within said receiving portion of said holder; and,    a plurality of substantially identically dimensioned cleaning surfaces that are substantially flat disposed on said exterior of said core allowing for said selectable positioning of said removable core to provide a clean surface for ink removal.    
     
     
         11 . The eraser of  claim 10  further comprising: 
 a scrapper.  
 
     
     
         12 . The eraser of  claim 11  further comprising: 
 a collector positioned to accept dust removed by said scrapper.  
 
     
     
         13 . The eraser of  claim 10  wherein the core is selected from the group consisting of foam, cork, felt, wood, plastic, cotton, synthetic fabric and a combination thereof.  
     
     
         14 . The eraser of  claim 10  wherein said core and said cleaning surfaces is provided by a one piece foam cube.  
     
     
         15 . The eraser of  claim 14  wherein said foam has an open celled structure.  
     
     
         16 . The eraser of  claim 9  further comprising: 
 a holding apparatus.  
 
     
     
         16 . The eraser of  claim 15  wherein said holding apparatus is felt.  
     
     
         17 . The eraser of  claim 10  further comprising: 
 an antistatic compound impregnated within said cleaning surfaces.  
 
     
     
         18 . A method of erasing whiteboards comprising the steps of: 
 providing a holder having a receiving portion;    providing a three dimensional polygonal object having a plurality of sides, each side individually capable of cleaning a white board;    selecting a clean surface on said three dimensional polygon to clean a white board;    inserting an opposing face to said clean surface on said polygon into said holder that is dimensioned to accept said polygon while leaving a portion of the adjacent side of said polygon projected beyond said holder perimeter; and,    cleaning ink from whiteboard.    
     
     
         19 . The method of  claim 18  further comprising: 
 wiping said white board with said clean surface until saturated with dry ink;  
 removing said three dimensional polygonal object from said holder;  
 reinserting said three dimensional polygonal object having a clean surface exposed from said holder.  
 
     
     
         20 . The method of  claim 19  further comprising: 
 scrapping the dry ink from sides of said polygonal object with a scrapper within said holder.
