Ergonomic handle for a fluid applicator spray gun

In a fluid applicator sprayer having a handle to be held in a hand of an operator, the improvement of an ergonomic handle comprising:

• a removable overlay elongated body attachable to the handle of the fluid applicator sprayer, the removable overlay elongated body having a base portion forming a distal end of the handle, a first longitudinally extending side portion and a second longitudinally extending side portion extending from the base portion, a termination point of the longitudinally extending side portions forming a proximal end of the handle, the handle defining an internal aperture located between the side portions conforming to an external surface of the handle of the fluid applicator sprayer, the side portions having an external convex gripping surface contoured to conform with the hand of the operator, and the base portion defining a port allowing an air-hose coupling to extend therethrough;
• the removable overlay elongated body having a first support shoulder with a proximal transverse surface and a distal transverse surface projecting transversely from the first longitudinal extending side portion nearer to the proximal end of the handle than the distal end;
• the proximal transverse surface of the first support shoulder sized to completely support a thumb of the operator and projecting at or near perpendicular to a central axis of the removable overlay elongated body;
• a second support shoulder with a proximal lateral surface and a distal lateral surface projecting laterally from the second longitudinally extending side portion nearer to the proximal end of the handle than the distal end, the second support shoulder located closer to the proximal end of the handle than the first support shoulder;
• and
• the distal lateral surface of the second support shoulder sized to accommodate a substantial second portion of an upper index finger surface of the operator and projecting at or near perpendicular to the central axis of the removable overlay elongated body.

• and
• a third support shoulder with a proximal surface and a distal surface projecting radially outwardly from the second longitudinally extending side portion nearer to the distal end of the handle, the proximal surface of the third support shoulder sized to accommodate a substantial third portion of a lower pinky finger surface of the operator and projecting at or near perpendicular to the central axis of the removable overlay elongated body.
