  • Patent number: 7874223
    Abstract: Constant force mechanisms and adjustable constant force mechanisms are described having two movable sliders constrained along two perpendicular axes and each abutting a resilient member. The mechanisms are adapted to produce an output force that is constant for a given input force. However, when an equilibrium position of one of the two resilient members is adjusted for a given mechanism, a different output force will result. Micro-compliant mechanisms are also described in which the resilient members may be made from one or more different elastomers.
