Coiled hose and spray nozzle

Abstract

A system for providing water for watering gardens, particularly plants, and for washing objects includes tubing having a coiled section that automatically retracts into a small coil when not in use. The tubing may be connected to various sources of water and a nozzle provides an adjustable spray pattern. The tubing is preferably polyurethane for ease of use. CROSS REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of U.S. application Ser. No. 09/377,853, now U.S. Pat. No. 6,209,800, the disclosure of which is hereby incorporated by reference. U.S. Pat. No. 6,209,800 is in turn a continuation of U.S. Pat. No. 5,964,412.

I claim:  
     
         1 . A fluid delivery system comprising an elongate flexible tube, an adjustable spray nozzle at one end of said tube, and a connector to a source of pressurized fluid at the opposite end of said tube, wherein said flexible tube is formed in extendible and contractible helical coils having opposed ends, said tube being comprised of polyurethane having a durometer hardness measurement in the range of 85 to 98 Shore A, an inner diameter in a range of from 0.360 to 0.4 inch, and an outer diameter in a range of 0.510 to 0.560 inch and being formed in coils having an inner diameter in a range of from 1.75 to 2.5 inches, the tube being so formed that adjacent coils when in a contracted position are pressed against each other, and wherein said wand, spray nozzle, and tube are sized to produce an appropriate flow of water such that said spray nozzle is operative to spray water in a pattern defined by a user.  
     
     
         2 . The system of    claim 1   , wherein said tube is comprised of polyurethane having a durometer hardness measurement in a range of 90 to 97 Shore A.  
     
     
         3 . The system of    claim 1   , wherein said tube is comprised of polyurethane having a durometer hardness measurement of about 95 Shore A.  
     
     
         4 . The system of    claim 1   , wherein said tube has an inner diameter of about 0.370 inch and an outer diameter of about 0.520 inch.  
     
     
         5 . The system of    claim 1   , wherein said tube is formed in coils having an inner diameter of about two inches.  
     
     
         6 . The system of    claim 1   , wherein said tube has a selected contracted length and is manually extendable to a length at least 14 times said contracted length.  
     
     
         7 . The system of    claim 1    wherein said spray nozzle has a single outlet aperture having a diameter in the range of from 0.200 inch to 0.275 inch.  
     
     
         8 . The system of    claim 7    wherein said diameter is 0.235 inch.
