Claim 14:
15. A support stand for an electronic device, the support stand comprising:
an arm assembly including:
a device attachment structure having a first attachment point and a second attachment point;
a support structure having a third attachment point and a fourth attachment point;
a first arm pivotally connected to the first attachment point and the third attachment point; and
a second arm pivotally connected to the second attachment point and the fourth attachment point; and

a counterbalance mechanism including:
a spring having a first end and a second end, wherein the spring comprises a compression spring;
a retainer pivotally connected to the arm assembly at a first pivot point and engaging the first end of the spring, the retainer enclosing the spring; and
a rod connecting the second end of the spring to the arm assembly at a second pivot point, the first pivot point being spaced apart from the second pivot point, the rod engaging the second end of the spring;

wherein rotation of the arm assembly about the third and fourth attachment points in a first rotational direction stores energy in the spring via movement of the rod relative to the retainer.
