Abstract
A display positioning apparatus is provided for lifting, supporting, and/or positioning a load, such as a display. The apparatus includes a base and a lift arm adapted to couple to a display, the lift arm pivotally coupled to the base providing a range of travel. A balance mechanism is operatively coupled to the lift arm and the base to counterbalance the lift arm and display. In some cases the balance mechanism includes a torquing spring member to counterbalance the lift arm and an attached display along the range of travel.
