Abstract:
1. An apparatus usable to support a computer display device, the apparatus comprising: a base having a bottom portion and an attached elevated support member; a display arm having a first end that is pivotally connected to the elevated support member; a counterweight arm that is separate and distinct from the display arm and having a first end that is pivotally connected to the elevated support member at a different location from where the display arm is pivotally connected to the elevated support member so that when the display arm is pivoted about the base, the counterweight arm pivots about the base to counterbalance a mass associated with at least the display arm thereby maintaining a center of mass of the apparatus over the base and minimizing a likelihood that the apparatus becomes unbalanced; a cam assembly that includes a first cam and a second cam, each cam being attached to the elevated support member at the different locations along the elevated support member, the first cam being further attached to the first end of the display arm, and the second cam being further attached to the first end of the counterweight arm; and a cable that is wrapped around the first cam and the second cam such that the counterweight arm and the display arm are indirectly coupled through the cam assembly and cable, such that a pivotal rotation of the display arm causes the counterweight arm to also pivotally rotate.
