ABSTRACT:
A flexural pivot for transferring an input force through a lever to develop an output force. The flexural pivot has a housing with a horizontal support and a vertical support. A first rectangular bar has a first end attached to the horizontal support and a second end attached to the lever. A second rectangular bar has a first end attached to the vertical support and a second end attached to the lever. The second ends of the first and second rectangular bars are attached to the lever to establish a fulcrum. The first bar holds the fulcrum in a substantially fixed horizontal position and the second bar holds the fulcrum in a substantially fixed vertical position whenever an input force is applied to the lever while allowing the lever to pivot about the fulcrum as a function of the twisting moment in the first and second bars.
