ABSTRACT:
A compound parallelogram four-bar linkage is provided wherein a first primary link is connected to a second primary link through connector links of substantially the same length and the pivotal angles of the first primary link and second primary link are maintained at substantially ninety degrees as movement is transferred from one primary link to the other so that the resonant frequency of the linkage does not vary and the linkage stiffness is independent of the angle of rotation.
