Scraper attachment for vacuum cleaners

Abstract

A device for attachment to a vacuum cleaner to combine the steps of scraping articles from a surface and removing the resulting debris. The device includes a first end which attaches to a vacuum cleaner. The second end of the device has a substantially rectangular shape. A slot is formed beneath the second end near the opening of the device. The slot has a first width slightly greater than the width of the safety end of a scraping blade. The slot also has a second width slightly greater than the width of scraping portion of the scraping blade. A scraping blade is inserted into the slot so that the scraping edge of the blade extends just in front of the opening of the second end of the device. Articles can then be removed from a surface by the blade. The debris which the results is sucked up through the second end and into the tank of a vacuum cleaner.

         6 . The attachment device of  claim 1  wherein said attachment device includes: 
 an adapter for allowing said attachment device to be used on different types of vacuum cleaners.  
 
     
     
         7 . The attachment device of  claim 1  wherein said first opening includes: a cylindrical shape.  
     
     
         8 . The attachment device of  claim 1  wherein said second opening includes: 
 a rectangular shape.  
 
     
     
         9 . The attachment device of  claim 1  wherein said attachment device includes: 
 means for changing the size of said second opening.  
 
     
     
         10 . An attachment device for a vacuum cleaner for scraping and removing articles from a surface, said attachment device comprising: 
 a body member;    a cylindrical shaped portion on a first end of said body member for attachment to a vacuum cleaner;    a substantially rectangular shaped portion on a second end of said body member opposite said first end;    an opening extending through said body member from said first end to said second end; and    means for holding a scraping blade having a scraping edge near said second end.    
     
     
         11 . The attachment device of  claim 10  wherein said means for holding a scraping blade having a scraping edge includes: 
 a clamp for clamping a scraping blade.  
 
     
     
         12 . The attachment device of  claim 10  wherein said means for holding a scraping blade further includes: 
 means for holding a scraping blade having a scraping edge and a second edge having a thicker dimension.  
 
     
     
         13 . The attachment device of  claim 12  wherein said means for holding a scraping blade includes: 
 a slot formed near said second opening having a width slightly larger than the width of the second edge of the scraping blade; and  
 a reduced width portion in said slot having a width slight larger than the width of scraping edge of the scraping blade.  
 
     
     
         14 . The attachment device of  claim 10  wherein said means for holding a scraping blade includes: 
 means for adjusting the angle of the scraping blade to said second opening.  
 
     
     
         15 . The attachment device of  claim 14  wherein said means for adjusting the angle of the scraping blade relative to said second opening includes: 
 a screw mounted in said means for holding a scraping blade and in contact with the scraping blade wherein movement of said screw causes the angle of the scraping blade to change relative to said second opening.  
 
     
     
         16 . The attachment device of  claim 10  wherein said attachment device further includes: 
 means for adapting said first opening to attach to various types of vacuum cleaners.  
 
     
     
         17 . The attachment device of  claim 10  wherein said body member further includes: 
 means for changing the size of the opening of said second end.  
 
     
     
         18 . An attachment device for a vacuum cleaner for scraping and removing articles from a surface, said attachment device comprising: 
 a body member;    a cylindrical shaped portion on a first end of said body member for attachment to a vacuum cleaner;    a substantially rectangular shaped portion on a second end of said body member opposite said first end;    an opening extending through said body member from said first end to said second end; and    a slot having a width slight larger than the width of a first end of a scraping blade formed in said second end beneath said opening in said second end; and    a reduced width portion having a width slightly larger than the width of a second end of the scraping blade formed in said slot near said opening in said second end.
