System and method for a debris shield that attaches to a vacuum shroud for tile removal

Abstract

A debris shield for use in conjunction with a vacuum shroud. The vacuum shroud attachment ring is configured to couple to the vacuum shroud and align its openings with the air intake openings of the vacuum shroud. The interior structure of the invention is such that a hook like structure extends from the opening closest to the vacuum shrouds air intake opening and acts to trap and deflect debris forcing it back into the vacuum shroud. Around the hook like structure there is an air passage configured to provide a continuous airway from the opening nearest where the air intake opening of the vacuum shroud is around to the outer edge of the vacuum shroud attachment ring.

         8 . The vacuum shroud attachment of  claim 7  wherein:
 the exterior air passageway wall further comprises:
 a vertical portion extending away from the base; 
 a flat portion that is parallel to the base and coupled to a point of the vertical portion that is distal from the base, the flat portion; 
 a terminal portion affixed at a section of the flat portion most distal to an area it coupled to the vertical portion. 
 
 
     
     
         9 . The vacuum shroud attachment of  claim 7  wherein:
 the vacuum shroud attachment is configured to detachably couple to a vacuum shroud. 
 
     
     
         10 . The vacuum shroud attachment of  claim 7  wherein:
 the plurality of vertical air passageway walls is coupled to a plurality of teeth. 
 
     
     
         11 . The vacuum shroud attachment of  claim 10  wherein:
 the plurality of teeth is configured to maintain a structure that narrows the air intake openings. 
 
     
     
         12 . The vacuum shroud attachment of  claim 7  wherein:
 the vacuum shroud attachment is comprised of at least one of a nylon, plastic, metal, rubber, Styrofoam, wood, ceramic, stone, wax, paper, glass, ice. 
 
     
     
         13 . A vacuum shroud attachment comprising:
 an exterior air passageway wall;   an interior air passageway wall located beneath the exterior air passageway wall such that an air passageway is formed between the exterior air passageway wall and the interior air passageway wall, the interior air passageway wall comprising;
 a first vertical portion extending away from a base towards the exterior air passage wall; 
   an air passageway configured to exist between the interior air passageway wall and exterior air passageway wall configured to be in fluid communication between a plurality of air intake openings and a plurality of air exit openings dispersed along the base;   a plurality of vertical air passageway walls extending from the base to the exterior air passageway wall configured to divide the air passageway into a plurality of air passageway which are in fluid communication from the air intake openings to the air exit openings.   
     
     
         14 . The vacuum shroud attachment of  claim 7  wherein:
