    • Methods and apparatus for providing an adjustable balancing force are provided. This mechanism can be used as a lifting force, a counter balancing mechanism or as a horizontal or other force mechanism. The force can be designed to be constant or variable over the range of motion by properly calculating the shape of the cam member. A balancing mechanism in accordance with the present invention includes a wheel comprising a pulley member and a cam member. A first cable connects the cam member of the wheel to a energy source for biasing the wheel to rotate in a first direction. A second cable is connected to the pulley member of the wheel for communicating a balancing or load force to the wheel. In some useful embodiments of the present invention, the cam member is shaped and positioned so that a torque applied to the wheel by the first cable is substantially constant while a force applied to the wheel by the first cable varies.
    • 提供了提供可调平衡力的方法和装置。 该机构可用作提升力,反平衡机构或水平或其他力机构。 可以通过适当地计算凸轮构件的形状,将力设计成在运动范围内是恒定的或可变的。 根据本发明的平衡机构包括:轮,其包括滑轮构件和凸轮构件。 第一电缆将轮的凸轮构件连接到能量源,用于偏置车轮以沿第一方向旋转。 第二电缆连接到车轮的滑轮构件,以将平衡或负载力传递到车轮。 在本发明的一些有用的实施例中,凸轮构件被成形和定位成使得由第一电缆施加到车轮的扭矩基本上是恒定的,而由第一电缆施加到车轮的力变化。
