Handheld Rotary Wheel Cleaning Brush

Abstract

A handheld rotary bristle brush head especially useful for cleaning the detail on vehicle wheels, as well as being useful for cleaning larger surfaces on the wheels and the vehicle. The brush head has a block with a generally dome-shaped main body of bristles, and a distinct forward cluster of bristles extending axially forward of the main body of bristles from a rounded end of the block in a flared cone. The forward bristle cluster has a smaller diameter than the main body of bristles, and can accordingly be applied to a surface or recess to be cleaned independently of the main body of bristles. The density and angle of the forward cluster gives a more thorough cleaning in tight, hard-to-reach spaces. The main body of bristles remains useful for cleaning larger surfaces.

1 . In a rotary cleaning bristle brush head adapted to be driven by a handheld motor drive unit to clean a vehicle, the brush head having a block and a main body of bristles extending from the block in generally dome-shaped fashion, the improvement comprising:
 a forward bristle cluster extending from a rounded outer end of the block in a flared cone, the forward bristle cluster having a smaller diameter than a diameter of the main body of bristles and comprising bristle ends axially spaced forwardly and distinct from the main body of bristles on the block, such that the bristle ends of the forward bristle cluster can be applied to a surface or recess to be cleaned without placing the main body of bristles in contact with the surface.   
   
   
       2 . The brush head of  claim 1 , wherein the forward bristle cluster has a bristle density greater than a bristle density of the main body of bristles. 
   
   
       3 . The brush head of  claim 1 , wherein outer bristles in the forward bristle cluster are flared and inner bristles in the forward bristle cluster are axial. 
   
   
       4 . The brush head of  claim 1 , wherein an outer angle of the forward bristle cluster is a forward angle closer to the block axis than the angle of the nearest portion of the main body of bristles.
