Abstract

A hand tool ( 10 ) for shaping joint compound ( 64 ) applied to a wall including a substantially rigid blade ( 12 ) having a handle ( 14 ), and wherein the blade ( 12 ) has a 5 preselected non-adjustable curvature ( 12 ).

Claims

exact text as granted — not AI-modified
1 . A hand tool for shaping joint compound applied to a wall comprising:
 a handle;   a blade supported on said handle;   a reinforcing member, attached to said blade, wherein said reinforcing member holds said blade at a pre-selected fixed curvature having a radius in a range of 100-300 inches.   
     
     
         2 . The hand tool of  claim 1 , wherein said curvature is substantially constant from a front edge of the blade to a back edge of the blade. 
     
     
         3 . The hand tool of  claim 1 , wherein said reinforcing member comprises a base and a pair of ribs extending outward therefrom relative to said blade. 
     
     
         4 . The hand tool of  claim 1 , wherein the blade curvature has a substantially constant radius from one side edge of the blade to the other side edge of the blade. 
     
     
         5 . A hand tool for shaping joint compound applied to a wall comprising:
 a blade which has a preselected non-adjustable curvature, wherein said blade is rigid such that it does not deform under forces applied during the shaping of joint compound and said pre-selected curvature is maintained during shaping; and   a handle attached and a said blade.   
     
     
         6 . The hand tool of  claim 5 , wherein said curvature is substantially constant from said front edge of the blade to a back edge of said blade. 
     
     
         7 . The hand tool of  claim 5 , further comprising a reinforcing member engaging said blade, wherein said reinforcing member comprises a base and a pair of ribs extending laterally therefrom. 
     
     
         8 . The hand tool of  claim 5 , wherein said pre-selected curvature has a radius in a range of 100 to 300 inches. 
     
     
         9 . The hand tool of  claim 5 , further comprising a reinforcing member extending from one side edge to an opposite side edge of said blade, said reinforcing member being located at a rear edge of said blade, and wherein said handle is attached to said reinforcing member and extends upward and rearward from said reinforcing member. 
     
     
         10 . The hand tool of  claim 9 , wherein said reinforcing member extends parallel to a front edge of said blade and is offset.
