Accessory to clean and recondition the rubber profile of windscreen wiper blades

Abstract

Accessory to clean and recondition the rubber profile ( 12 ) of windscreen wiper arms ( 13 ) comprising a containing body ( 14 ) shaped substantially like an upside-down U, open on one side ( 14 a ) and housing scraping and/or abrasive means The scraping and/or abrasive means may consist of scraping blades or cylindrical milling wheels made to rotate by rubber rollers.

1 . Accessory to clean and recondition the rubber profile ( 12 ) of windscreen wiper arms ( 13 ), characterised in that it comprises a containing body ( 14 ) shaped substantially like an upside-down U, open on one side ( 14   a ) and housing scraping and/or abrasive means ( 2 ,  5 ,  6 ).  
     
     
         2 . Accessory as in    claim 1   , characterised in that the scraping and/or abrasive means consist of at least a row of blades ( 2 ) suitable to act on at least one side of the rubber profile ( 12 ) of the wiper arm ( 13 ).  
     
     
         3 . Accessory as in    claim 2   , characterised in that it has two opposite rows of blades ( 2 ) suitable to act simultaneously on both sides of the rubber profile ( 12 ).  
     
     
         4 . Accessory as in    claim 2    or    3   , characterised in that the blades ( 2 ) are arranged substantially orthogonal to the rubber profile ( 12 ) to be cleaned.  
     
     
         5 . Accessory as in    claim 2    or    3   , characterised in that the blades ( 2 ) are arranged in a herring-bone pattern with the respective ends ( 2   a ) of one row of blades ( 2 ) converging towards the ends ( 2   a ) of the opposite blades ( 2 ).  
     
     
         6 . Accessory as in any claim hereinbefore, characterised in that it comprises a plurality of blades ( 5 ) suitable to exert a scraping action on the outer edge ( 12   a ) of the rubber profile ( 12 ).  
     
     
         7 . Accessory as in    claim 1   , characterised in that the scraping and/or abrasive means consist of at least a pair of cylindrical milling wheels ( 6 ) elastically constrained together to exert a cleaning action on the sides of the rubber profile ( 12 ).  
     
     
         8 . Accessory as in    claim 7   , characterised in that the cylindrical milling wheels ( 6 ) are driven by contact with rubber rollers ( 7 ) made to rotate by the rubber profile ( 12 ) passing through said rollers ( 7 ).  
     
     
         9 . Accessory as in    claim 7   , characterised in that the cylindrical milling wheels ( 6 ) are inclined downwards with respect to the horizontal plane.  
     
     
         10 . Accessory as in    claim 1   , characterised in that it has at least on one side a funnel-shaped mouth ( 3 ) which facilitates the insertion of the rubber profile ( 12 ) inside the accessory ( 1 ).  
     
     
         11 . Accessory as in    claim 10   , characterised in that in correspondence with the mouth ( 3 ) it has bow-shaped guide means ( 9 ) which act as guides for the rubber profile ( 12 ).  
     
     
         12 . Accessory as in    claim 1   , characterised in that it has knurling ( 15 ) on the outer surface which facilitates gripping and manipulation.
