Speed sand 90 systems

Abstract

Speed Sand 90 is a device designed to quickly and efficiently create accurate ninety-degree angles while sanding new drywall. The device may be modular and/or a non-modular. The non-modular version may comprise two main parts: a replacement pad and a tool portion (a perpendicularly-angled mounting beam and manipulator securer). The replacement pad may be a ninety-degree sponge with two aggregated sides. The tool portion of the device may comprise plastic or other suitable durable material. A universal ball joint, designed to accept any standard corner flushing handle, can be located at the center-back portion of the tool. The replacement pad may attach to the perpendicularly-angled mounting beam with adhesive material. The modular version may comprise slidably-removably-attachable wings having leading and trailing edges providing that the sanding device can be efficiently and effectively used in conjunction with an abrasive sponge to sand inside corners.

         5 . The drywall corner sanding assembly of  claim 1  wherein said drywall corner sanding assembly comprises plastic. 
     
     
         6 . The drywall corner sanding assembly of  claim 1  wherein said universal ball joint is designed to accept at least one OEM corner flushing handle. 
     
     
         7 . The drywall corner sanding assembly of  claim 1  wherein said perpendicularly-angled mounting beam receives said replacement abrasive pad using a fastener. 
     
     
         8 . The drywall corner sanding assembly of  claim 7  wherein said fastener comprises at least one adhesive. 
     
     
         9 . The drywall corner sanding assembly of  claim 7  wherein said fastener comprises hook and loop fasteners. 
     
     
         10 . The drywall corner sanding assembly of  claim 3  wherein said ninety degree sponge with two aggregated surfaces comprises a flexible porous interior. 
     
     
         11 . The drywall corner sanding assembly of  claim 3  wherein said ninety degree sponge with two aggregated surfaces comprises a semi-flexible exterior. 
     
     
         12 . The drywall corner sanding assembly of  claim 3  wherein said ninety degree sponge with two aggregated surfaces is manipulatable such that simultaneous abrasive removal of excess drywall compound from both said first side adjacent and said second side adjacent said interior corner occurs when used. 
     
     
         13 . The drywall corner sanding assembly of  claim 12  wherein said ninety degree sponge with two aggregated surfaces is manipulatable such that abrasive removal of said excess drywall compound from said first side adjacent of said interior corner occurs. 
     
     
         14 . The drywall corner sanding assembly of  claim 12  wherein said ninety degree sponge with two aggregated surfaces is manipulatable such that abrasive removal of said excess drywall compound from said second side adjacent of said interior corner occurs. 
     
     
         15 . The drywall corner sanding assembly of  claim 12  wherein said ninety degree sponge with two aggregated surfaces is manipulatable such that simultaneous abrasive removal of said excess drywall compound from said interior corner does not cause gouging in either of said first side adjacent and said second side adjacent said interior corner. 
     
     
         16 . The drywall corner sanding assembly of  claim 1  wherein said interior corner comprises a ninety degree angle. 
     
     
         17 . The drywall corner sanding assembly of  claim 1  further comprising a slider-biasing-clip for engaging said attachable manipulator pole. 
     
     
         18 . The drywall corner sanding assembly of  claim 1  wherein said manipulator securer comprises a wedge profile, an opposed-facing inner slider track wherein a slider-biasing-clip can be moved to biasingly engage and/or disengage from said attachable manipulator pole. 
     
     
         19 . A drywall corner sanding assembly for use on interior corners comprising:
 a modular beam having,
 a first wing, 
 a second wing, and 
 a center portion; 
 a sponge approximately 7″ long, having as a width along an abrasive side of about 4″, and approximately ¾″ thick, said sponge angle forms a right angle one-piece L-construction, said abrasive forming a coating on an outside of said sponge and said abrasive is continuous; 
   wherein said first wing and said second wing slidingly removably attach to said center portion to form said modular beam;   wherein said modular beam has leading and trailing edges;   wherein said modular beam tapers from about 100 degrees to about 90 degrees along its length, defining said leading edge and said trailing edge such that sanding pressure is displaced through said first wing and said second wing and said center portion according to said sanding pressure applied on said leading edge and said trailing edges;   wherein said modular beam is designed to fit on a standard flusher handle;   wherein said modular beam provides a surface to support said sponge for use on interior corners during sanding activities.   
     
     
         20 . A method for using a drywall corner sanding assembly on interior corners comprising the steps of:
 attaching a replacement abrasive pad comprising an L-shaped sponge via a fastener to a surface of a perpendicularly-angled mounting beam via adhesive, and/or hook and loop fasteners;   inserting an attachable manipulator pole into a manipulator securer located on a back portion of said perpendicularly-angled mounting beam;   sliding a slider-biasing-clip in a track on said manipulator securer to biasingly engage to said attachable manipulator pole; and   sanding an interior corner of drywall such that simultaneous abrasive removal of excess drywall compound from both a first side adjacent and a second side adjacent said interior corner occurs when used and does not cause gouging in either of said first side adjacent and said second side adjacent said interior corner.
