Drywall Sander

Abstract

A sanding tool including a blade and a handle, the blade having first and second opposing faces. An attachment layer removably secures to the sanding tool at the opposing faces, thereby to provide opposing abrasive layers on opposing sides of the blade. The shape of the blade, with a wider yet thinner top end, and a reduced thickness from a bottom side thereof to a top edge thereof, reduces hand strain when sanding drywall, and also helps to assure uniform sanding and avoidance of hand injury when sanding corners, in a cost-effective manner.

We claim: 
     
         1 . A drywall sander comprising:
 a substantially rigid blade having a first face and a second face, a top edge, and a bottom side;   a substantially elongated handle extending from the bottom side of the blade; and   an abrasive layer, wherein the abrasive layer covers a first portion on the first face of the blade, extends over the top edge, and covers a second portion on the second face of the blade.   
     
     
         2 . The drywall sander of  claim 1  further comprising:
 a substantially thin backing layer, wherein the backing layer is positioned between the blade and the abrasive layer on both the first face and the second face of the blade. 
 
     
     
         3 . The drywall sander of  claim 1 , wherein the width of the blade decreases from the top edge to the bottom side. 
     
     
         4 . The drywall sander of  claim 1 , wherein the abrasive layer is sandpaper. 
     
     
         5 . The drywall sander of  claim 2 , wherein the backing layer further comprises a buffer layer of foam. 
     
     
         6 . The drywall sander of  claim 2 , wherein the blade decreases in thickness from the bottom side to the top edge. 
     
     
         7 . An attachment for a drywall sander comprising:
 an abrasive layer;   a backing layer supporting the abrasive layer;   a substantially central fold, wherein the fold establishes a first fold side and a second fold side; and   an attachment associated with the backing layer, whereby the attachment may be positioned on a substantially flat and substantially rigid surface having a first face, a second face, and a top edge such that the first fold side is positioned over a first portion of the first face of the surface, the second fold side is positioned over a second portion of the second face of the surface, and the fold is positioned substantially over the top edge of the surface, and wherein the attachment is positioned such that the backing layer may be releasably attached to the first and second faces so as to substantially expose the abrasive layer in opposite directions.   
     
     
         8 . The drywall sander attachment of  claim 7 , wherein the abrasive layer and the backing layer comprise sandpaper. 
     
     
         9 . The drywall sander attachment of  claim 7 , wherein the backing layer comprises a layer of foam. 
     
     
         10 . The drywall sander attachment of  claim 9  wherein the blade decreases in thickness from the bottom side to the top edge. 
     
     
         11 . The drywall sander attachment of  claim 10  wherein, on each side thereof, the shape of the abrasive layer is specific to a designated region of the blade.
