Hydrodynamic pool brush

Abstract

An improved swimming pool brush employing a true wing shape. Consisting of a leading edge continuing to a wing surface that is decreasing in its radius, concave or continually converging toward its leading edge, terminating at the trailing edge. This decreasing radius will empart a greater down force as the liquid passes over the surface, urging the brush against the surface being cleaned. A plurality of slots are incorporated into the surface to allow water to pass through to the rear of the wing surface which acts to cancel out any drag producing low pressure areas. On the return stroke, these slots allow water to pass from back to front decreasing the drag on the brush for effortless retrieval.

I claim:  
     
         1 . A swimming pool brush that is originally constructed with a shape to force said brush bristles against a pool's inner surfaces using hydrodynamic principles with forward movement, comprising: 
 a. an inverted wing design.    b. an upwardly curving radius from the leading edge to the trailin edge.    c. brush head mounted:    d. a slot as a means for the wing to allow fluid flow through on forward movement whereby cancelling any drag producing low pressures behind said wing, additionally minimizing effort needed upon retrieval.    
     
     
         2 . The brush of  claim 1  wherein said radius is constant in degrees.  
     
     
         3 . The brush of  claim 1  wherein said radius is decreasing in degrees.  
     
     
         4 . The brush of  claim 1  wherein said inverted wing angle can be adjusted to create variable downforces.  
     
     
         5 . The brush of  claim 1  wherein said brush head has a plurality of slots.  
     
     
         6 . The brush of  claim 5  wherein said slots can be horizontal in orientation.  
     
     
         7 . The brush of  claim 5  wherein said slots can be vertical in orientation.  
     
     
         8 . The brush of  claim 1  wherein said wing can be separately constructed.  
     
     
         9 . The brush of  claim 8  wherein said wing can be secured to a swimming pool brush by fasteners.  
     
     
         10 . The brush of  claim 1  wherein said brush molded from the group consisting of plastics.  
     
     
         11 . The brush of  claim 1  wherein said brush can be stamped from the group consisting of non-corrosive metals.  
     
     
         12 . The brush of  claim 1  wherein said brush uses flexible materials.  
     
     
         13 . The brush of  claim 1  wherein said brush is constructed with a plurality of said wing design.
