Abstract
Embodiments provide a counterbalancing lift mechanism for raising and lowering an electronic display. The lift mechanism includes a moving bracket in sliding engagement with a support bracket. As the moving bracket moves relative to the support bracket, a spring assembly deflects to provide a force to offset the weight of the load. A transition assembly manages the deflection of the spring assembly relative to movement of the moving bracket such that the necessary range of deflection is shorter than the moving bracket's desired range of travel. The lift mechanism also includes a cam assembly to convert the variable force from the spring assembly to a substantially constant force. In some cases the spring assembly, transition assembly, and cam assembly are all mounted to the moving bracket and move with the display. Methods for positioning an electronic display are also provided.
