Manual swimming pool cleaning apparatus employing a plurality of water jets

Abstract

A swimming pool cleaning apparatus comprises a number of joined sections of tubing or pipe in a generally T-shaped configuration. The pipe is preferably PVC pipe. The preferred embodiment comprises an elongated hollow pipe section referred to herein as the head. The head is preferably about 28 inches in length, although lengths of about 20 inches to about 40 inches have been shown to be suitable as well. The PVC pipe used in the preferred embodiment is standard half-inch PVC pipe, but other size PVC may also be suitable. The head pipe has a plurality of aligned 1/16 inch diameter holes drilled through the pipe along its length. In the preferred embodiment, these holes are drilled at different angles relative to the longitudinal axis of the head. One or two of these holes are drilled to be perpendicular to the head axis while holes to either side of the perpendicular holes are drilled to have an angular offset of about 5° from hole to adjacent hole. This offset provides a more effective cleaning pattern.

1 . A swimming pool cleaning apparatus comprising:
 a water jet head in the form of a pipe having a plurality of water exit holes for propelling water under pressure toward underwater pool surfaces;   a pole stub extending from said head for attachment of said apparatus to a pool cleaning pole; and   a hose connector in fluid communication with said head exit holes and adapted to receive the end of a hose for delivering water under pressure to said head for propulsion through said exit holes.   
     
     
         2 . The pool cleaning apparatus recited in  claim 1  wherein said water jet head comprises an elongated pipe having a tee connection along the length of said pipe. 
     
     
         3 . The pool cleaning apparatus recited in  claim 1  wherein said water jet head is made of a length of PVC pipe. 
     
     
         4 . The pool cleaning apparatus recited in  claim 1  wherein said water jet head is made of plastic pipe and wherein said water exit holes are formed by drilling holes in the pipe. 
     
     
         5 . The pool cleaning apparatus recited in  claim 1  wherein said. plurality of water exit holes comprise a series of drilled holes along a linear path on said head, the respective drill axes of said holes being angled at selected directions relative to said head for providing a pattern of water jets. 
     
     
         6 . The pool cleaning apparatus recited in  claim 1  wherein said plurality of exit holes comprises at least one drilled hole having an axis that is perpendicular to said head, the axes of the remaining exit holes being at 5° angular increments relative to said at least one perpendicular drilled hole. 
     
     
         7 . The pool cleaning apparatus recited in  claim 1  further comprising mating rotatable flanges connecting said pole stub to said head for angular adjustment of said head relative to said pole. 
     
     
         8 . A swimming pool cleaning apparatus comprising:
 a length of capped pipe having a series of holes at selected intervals forming water jet orifices for cleaning underwater surfaces of a swimming pool; said pipe having a tee connected along its length for receiving a water hose delivering pressurized water to said series of holes; and a stub extending from said tee for connection to a pole for holding said pipe under the surface of said pool.   
     
     
         9 . The swimming pool cleaning apparatus recited in  claim 8  wherein said length of capped pipe is made of polyvinyl carbonate. 
     
     
         10 . The swimming pool cleaning apparatus recited in  claim 9  wherein said series of holes comprises a plurality of drilled holes having different axial directions to form a selected pattern of water jets. 
     
     
         11 . The swimming pool cleaning apparatus recited in  claim 10  wherein said axial directions of said drilled holes differ from one another by at least 5°. 
     
     
         12 . The swimming pool cleaning apparatus recited in  claim 8  further comprising mating adjustment flanges interconnecting said stub and said tee for adjusting the angular orientation between said pipe and said pole.
