ABSTRACT:
An improved apparatus for supporting a frame for pivotation of the frame relative to a selected axis of pivotation. A plurality of connectors are attached to the frame at pivot support points on the frame, and the connectors are supported by a plurality of bearing posts that are arranged in a determined geometric relationship such that each connector is movable on its respective bearing post along an axis of travel, the axis of travel for each of the connectors passing through a common travel axis convergence point. The determined geometric relationship further directs the frame to have a positional reference mode in which all of the pivot support points are positioned on the circumference of a reference circle that intersects the axis of pivotation at an initial pivotation center, the initial pivotation center being located at one end of a reference diameter of the reference circle, and the travel axis convergence point being located at the other end of the reference diameter.
