    • Embodiments provide a counterbalancing lift mechanism (100) for raising and lowering an electronic display. The lift mechanism includes a moving bracket (110) in sliding engagement with a support bracket (120). As the moving bracket moves relative to the support bracket, a spring assembly (130) deflects to provide a force to offset the weight of the load. A transition assembly (149) 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 (170) 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.
    • 实施例提供了用于升高和降低电子显示器的平衡提升机构(100)。 提升机构包括与支撑托架(120)滑动接合的移动支架(110)。 当移动支架相对于支撑托架移动时,弹簧组件(130)偏转以提供力以抵消负载的重量。 过渡组件(149)管理弹簧组件相对于移动支架的运动的偏转,使得必要的偏转范围比移动支架的期望行程范围短。 提升机构还包括凸轮组件(170),用于将来自弹簧组件的可变力转换成基本恒定的力。 在一些情况下,弹簧组件,过渡组件和凸轮组件都安装到移动支架上并与显示器一起移动。 还提供了用于定位电子显示器的方法。
