Lifting extension mount assembly for equipoising arms

A lifting extension mount assembly comprising:

• an extension mount component having a proximate end and a distal end and configured to be rigidly fixed to an object at its proximate end;
• a lifting segment having a proximate end and a distal end;
• the lifting segment attached at its proximate end to the distal end of the extension mount component at an extension mount component attachment point and pivotable with respect to the extension mount component at the attachment point in a vertical plane only;
• the lifting extension mount assembly attachable to a two-segment lifting arm;
• an angle-adjustment assembly to maintain substantially vertical lifting segment proximate and distal parallelogram sides in relation to an operator's preferred posture;
• wherein the arm-angle adjustment assembly comprises:
• a first rocker block pivotable about a first axis;
• a second rocker block pivotable about a second axis perpendicular to the first axis;
• first rocker block screws disposed through the first rocker block and by which the first rocker block can be adjusted about the first axis;
• and
• second rocker block screws disposed through the second rocker block and by which the second rocker block can be adjusted about the second axis.
