Abstract
A display positioning apparatus is provided for lifting, supporting, and/or positioning a load, such as a display. The apparatus includes a support and a bracket adapted to couple to a display movably coupled to the support along a range of travel. A balance mechanism is operatively coupled to the bracket and support to counterbalance the bracket and display. In some cases the balance mechanism includes a torquing spring member operatively coupled with a cam member to provide a substantially constant counterbalancing force along the range of travel.
