ABSTRACT:
An ergonomic hand held paint spray gun which reduces operator fatigue and stress. The handle of spray gun has an ergonomically designed shape and the size of the handle may be changed through the use of different size handle covers. The spray gun has a plurality of triggers arranged to be operated by different fingers and to facilitate operation when the gun is held in different orientations to reduce fatigue and operating frequency stress on an operator's fingers. Some of the triggers operate low force valves which supply pilot air to a pilot valve which opens the fluid and air valves. The paint and air hoses may be attached to alternate locations on the gun to reduce hand and wrist fatigue when painting predominantly vertical surfaces or predominantly horizontal surfaces. A junction box may be located in the paint and air hoses to allow connection of lighter weight hoses to the gun. The junction box is located to be held in the operator's free hand and an optional trigger valve may be located on the junction box for supplying pilot air to remotely trigger the fluid and air valves in the gun. For operating an HVLP gun, a pressure regulator may be located in the junction box to drop high pressure air to the high volume low pressure air flow required by the gun.
