High-pressure paint sprayer wand
First Claim
Patent Images
1. A high-pressure paint sprayer wand comprising:
- (a) a flexible high-pressure line having a spray gun coupling at one end for coupling to a high-pressure spray gun and a nozzle coupling at the other end for coupling to a paint spray head;
(b) a generally cylindrical sheath having a larger internal diameter than the external diameter of said line and extending around at least a portion of the length of said high-pressure line;
(c) said sheath comprising a bendable shape-retaining conduit having substantially no memory such that it remains in a curved shape into which it is bent until it is rebent into a subsequent configuration; and
,(d) said couplings comprising threaded fittings having rigid line ferrules engaging over the respective ends of said line, and said sheath having a sheath ferrule at each end which is crimped over the respective line ferrules to hold the respective ends of said conduit and line together.

Abstract
A wand is used to attach to the output of a high-pressure spray gun, with the nozzle or sprayer connected to the other end of the wand. The wand has the characteristics of containing the high-pressure delivered by the spray gun at about 3000 PSI in an internal high-pressure, highly flexible line, which is captured within an external, bendable sheath which retains the shape into which it is bent, so that paint may be more conveniently sprayed in corners and out-of-the-way places.
