Abstract
An articulating support arm includes a base, a first set of control arms having proximal ends and distal ends, with the proximal ends of the first set of control arms being pivotally connected to the base. The support arm further includes a second set of control arms having proximal ends and distal ends, with the proximal ends of the second set of control arms being disposed forward of and pivotally connected to the distal ends of the first set of control arms. The distal ends of the second set of control arms also are pivotally connected to a control head, and a locking assembly selectively prevents pivotal movement of the control arms, so as to provide vertical adjustment of the control head relative to the base.

An articulating support arm comprising:
- a base,
- a first set of control arms having proximal ends and distal ends;
- the proximal ends of the first set of control arms being pivotally connected to the base;
- a second set of control arms having proximal ends and distal ends;
- the proximal ends of the second set of control arms being disposed forward of and pivotally connected to the distal ends of the first set of control arms;
