ABSTRACT:
Mechanical linkage comprising two pairs of flexure elements constrains the motion of a reference member to be along a reference axis even in the presence of applied moments. The linkage includes a pair of V-shaped flexure elements coupled at their vertex ends to the reference member at points along the reference axis. One of these flexure elements is coupled at its distal ends to a support member fixed with respect to the reference axis. The other of the V-shaped flexure elements is coupled at its distal ends to one of a pair of elongated flexure elements at a point between its two ends. The pair of elongated flexure elements are affixed at one end to the support member and at their other end are adjustably coupled to the support member. This arrangement permits "fine tuning" of the reference axis so that the linkage exhibits the desired high resistance to moments applied to the reference member.
