Abrasive cleaning device

Abstract

A cleaning element ( 36 ) for a cement floor surface mounted to a housing ( 32 ). Each cleaning element has a flat flexible abrasive surface ( 39 ) that is transversely positioned to the direction of motion to provide flex during cleaning of a cement floor surface.

1 . An abrasive cleaning device comprising: 
 a housing    a plurality of cleaning strips having a front abrasive face with a width and length;    said cleaning strips mounted to said housing such that the front abrasive face is aligned substantially transverse to the normal direction of motion of said housing;    said cleaning strips having a substrate and an abrasive material at the surface of said cleaning strips and secured to said substrate; and    the length of said cleaning strips being substantially greater than its thickness to provide flexibility of said cleaning strips.    
   
   
       2 . An abrasive cleaning device as defined in  claim 1  further comprising: 
 said abrasive material being hard abrasive particles being embedded in said substrate; and    said substrate is a plastic matrix.    
   
   
       3 . An abrasive cleaning device as defined in  claim 2  further comprising: 
 said plastic matrix being a high temperature plastic.    
   
   
       4 . An abrasive cleaning device as defined in  claim 1  further comprising: 
 said housing being a rotatable pad made for rotation about a central point; and    said cleaning strips having its front abrasive faces substantially radially aligned with the center of said pad.    
   
   
       5 . An abrasive cleaning device as defined in  claim 1  further comprising: 
 said housing being tubular and made for rotation about its major axis; and    said cleaning strips extend radially from said housing with the front abrasive faces co-aligned with the major axis.

       14 . An abrasive cleaning device comprising: 
 a housing;    a plurality of cleaning strips having a substrate with a mounting end mounted to said housing and a distal end with an abrasive material at the surface of said substrate and secured to said substrate;    the length of said cleaning strips being substantially greater than its thickness to provide flexibility of said cleaning strips; and    said cleaning strips in cross-section having a major axis and a minor axis with one of said axes positioned to be transverse to the normal motion of said housing.    
   
   
       15 . An abrasive cleaning device as defined in  claim 14  further comprising: 
 said major axis being positioned transversely to the normal motion of said housing.    
   
   
       16 . An abrasive cleaning device as defined in  claim 15  further comprising: 
 said housing being a rotatable pad made for rotation about a central point; and    said cleaning strips having their respective major axis substantially radially aligned with the center of said pad.    
   
   
       17 . An abrasive cleaning device as defined in  claim 16  further comprising: 
 said abrasive material comprising diamond particles having a brazed connection with said substrate.    
   
   
       18 . An abrasive cleaning device as defined in  claim 15  further comprising: 
 said abrasive material comprising diamond particles having a brazed connection with said substrate.    
   
   
       19 . An abrasive cleaning device as defined in  claim 18  further comprising: 
 said substrate being a metallic material    
   
   
       20 . An abrasive cleaning device as defined in  claim 15  further comprising: 
 said cleaning strips having a major and minor axis greater than 1/8 inch such that it is larger than the diameter of cement pores.    
   
   
       21 . An abrasive cleaning device for a concrete surface comprising: 
 a brush with a plurality of resiliently flexible bristles having a major and minor axis larger than the pores of said concrete;    said brush having a scrub working surface with abrasive particles affixed thereto;    said brush having a flat edge at its distal end to scrape away dirt and residue; and    said brush providing a replenished scrub working surface as worn abrasive particles abrade from the scrub working surface and as the scrub working surface abrades away for honing the concrete surface.

       23 . (canceled)  
   
   
       24 . An abrasive cleaning device as defined in  claim 1  further comprising: 
 said front abrasive faces being substantially flat.    
   
   
       25 . An abrasive cleaning device as defined in  claim 15  further comprising: 
 said front abrasive faces being substantially flat.    
   
   
       26 . An abrasive cleaning device as defined in  claim 21  further comprising: 
 said scrub working surface being substantially flat and substantially transverse to the normal direction of motion of said cleaning device.    
   
   
       27 . An abrasive cleaning device as defined in  claim 1  further comprising:
