Ergonomic handle for a fluid applicator spray gun

摘要

An ergonomic handle assembly can allow an operator to comfortably support weight of a fluid filled reservoir connected to a fluid applicator sprayer. Any combination of first, second and third shoulders can be formed on the handle assembly to provide increased support surface area in three dimensions with respect to a hand of an operator supporting the fluid applicator spray gun for distributing weight across both the palm and fingers through a proximal support surface of the first support shoulder, the distal support surface of the second support shoulder, and the proximal support surface of the third support shoulder. The increased support surface area can allow an operator to support and handle the fluid applicator spray gun with reduced gripping force when compared to existing fluid applicator spray guns. The reduced gripping force can reduce the likelihood of repetitive stress syndrome injuries to the hand and arm of an operator.

主权项

1. An ergonomic handle for a fluid applicator sprayer to be held in a hand of an operator, the ergonomic handle comprising:
an elongated body having a base portion forming a distal end of the handle, the elongated body extending from the distal end and terminating at a topmost point forming a proximal end of the handle; the elongated body including a contoured and convex external surface conforming to the hand of the operator; the elongated body having a first support shoulder with a proximal transverse surface and a distal transverse surface projecting transversely from the elongated body and located nearer to the proximal end of the elongated body 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 elongated body; a second support shoulder with a proximal lateral surface and a distal lateral surface projecting laterally from the elongated body and located nearer to the proximal end of the elongated body than the distal end, the second support shoulder located in an orientation opposite the first support shoulder, the second support shoulder located closer to the proximal end of the elongated body 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 elongated body.
