Swimming pool cleaning tool

Abstract

The present invention is a swimming tool cleaning tool that does not require the exertion of vertical force against the vertical surfaces of the swimming pool for effective cleaning. The person using the present invention only needs to push and pull on the cleaning tool to use it effectively to clean the swimming pool. The present invention has one or more movable blade in the shape of a foil pivotally attached to back of the cleaning pad that will pivot in the direction of the movement of the cleaning tool by utilizing hydrodynamics wherein the present invention will generate a vertical force on the cleaning pad forcing the cleaning pad against the surface regardless of the forward or backward movement of the cleaning tool. The present invention will direct the bulk of the hydrodynamic forces on the back of the cleaning pads. The present invention is especially efficient in quickly cleaning the bottom of a large swimming pool such as those used in public and commercial establishments.

What is claimed is:  
     
         1 . A swimming pool cleaning tool comprising: 
 a cleaning pad affixed to a pad holder with two ends;    a rudder is affixed at each of the two extremes on the other side of the pad holder opposite the cleaning pad;    one or more blade in the shape of a foil is pivotally attached to the back of the pad holder with a pivot attachment means;    wherein the blade will pivot toward the direction of the movement of the cleaning pad under water to generate a vertical downward force against the surface to be cleaned and will pivot to the other direction when the movement of the cleaning pad changes to the other direction while offering minimum tangential resistance and travels in a linear movement.    
     
     
         2 . A swimming pool cleaning tool as in  claim 1 , wherein each said pivot attachment means comprises of two parallel blade adjusters affixed to the back of the pad holder between the two rudders wherein each blade adjuster is in the shape of a semi-circle with a slot parallel to its circumference, two blade holders are affixed to the underside of the blade near the two extremes of the blades wherein the blade holders are pivotally attached with blade holding screws to the blade adjusters on the back of the pad holder, a pushing rod is rotably inserted through the blade holders and pivots within the slots in the blade adjusters, a pushing rod stopper is attached to each of the two ends of the pushing rod to retain the pushing rod within the pivot attachment means assembly, a rod connector in the general form of the letter “T” is affixed at the middle of the pushing rod between the two blades by two fasten screw, and a holding rod is pivotally attached to the rod connector with a master screw and oriented perpendicular to the pushing rod.  
     
     
         3 . A swimming pool cleaning tool comprising: 
 a cleaning pad affixed to a pad holder with two ends;    a rudder is affixed at each of the two extremes on the other side of the pad holder opposite the cleaning pad;    one or more blade in the shape of a foil is pivotally attached to the back of the pad holder with a pivot attachment means;    one or more ropes are attached to the pivot attachment means such that the swimming pool cleaning tool may be pulled by the ropes in opposite directions;    wherein the blade will pivot toward the direction of the movement of the cleaning pad under water to generate a vertical downward force against the surface to be cleaned and will pivot to the other direction when the movement of the cleaning pad changes to the other direction while offering minimum tangential resistance and travels in a linear movement.    
     
     
         4 . A swimming pool cleaning tool as in  claim 3 , wherein each said pivot attachment means comprises of two parallel blade adjusters affixed to the back of the pad holder between the two rudders wherein each blade adjuster is in the shape of a semi-circle with a slot parallel to its circumference, two blade holders are affixed to the underside of the blade near the two extremes of the blades wherein the blade holders are pivotally attached with blade holding screws to the blade adjusters on the back of the pad holder, a pushing rod is rotably inserted through the blade holders and pivots within the slots in the blade adjusters, a pushing rod stopper is attached to each of the two ends of the pushing rod to retain the pushing rod within the pivot attachment means assembly, a rod connector in the general form of the letter “T” is affixed at the middle of the pushing rod between the two blades by two fasten screw, and one or more ropes are attached to the rod connector to pull the swimming pool cleaning tool through water at the bottom of a large swimming pool.
