Squeegee for curved surfaces

Abstract

A T-shaped squeegee for any smooth surface, contoured or flat, comprises a thin elastic cleaning element with two parallel cleaning edges, a supporting curved and protruding rigid blade that can produce continuously varied curvature by changing the angle of attack, a handle, and holder that connect the blade and the handle. This combination of thin elastic cleaning element with channel shaped cross-section and contour matching ability of the blade provides sufficiently high contact pressure on a wide curve for removing tightly adhered dirt, efficiently.

1 . A cleaning device for a smooth contoured or flat surface comprising: 
 a T-shaped blade having a curved face, a mounting tab at the bottom and a wide protruding topside with a pair of narrow ends,    an elastic cleaning element having means for mounting on said blade securely and covering said topside to provide a pair of parallel protruding arc-shaped cleaning edges,    a handle, and    a connecting means between said mounting tab and said handle.    
   
   
       2 . The cleaning device of  claim 1  wherein said blade is a metal plate with uniform thickness.  
   
   
       3 . The cleaning device of  claim 1  wherein said blade is an injection molded plastics.  
   
   
       4 . The cleaning device of  claim 1  wherein said tab is a substantially rectangular and uniform in thickness.  
   
   
       5 . The cleaning device of  claim 1  wherein said element is a strip with rectangular exterior surfaces, slightly thicker than said blade and slightly shorter than the width of said topside of said blade.  
   
   
       6 . The cleaning device of  claim 1  wherein said mounting means is a T-shaped cavity in said elastic element  
   
   
       7 . The cleaning device of  claim 1  wherein said connecting means is a pinched metal tubing having a substantially rectangular opening for said mounting tab at one end and a round opening for said handle at the opposite end.  
   
   
       8 . The cleaning device of  claim 7  wherein said handle has a pair of bevels on one end that mate with a pair of slanted inside faces of said tubing.
