ABSTRACT:
An apparatus for causing relative movement of first and second structures about a pivot axis is disclosed wherein a rotatable, elongated member has first and second portions which respectively extend from the pivot axis toward the first and second structures. The second portion of the member extends rotatably within a housing which is also rotatable with respect to the second structure. The axis of rotation of the member second portion within the housing is skewed from the axis or rotation of its first portion relative to the first structure by an angle .theta. and is also skewed by an equal angle from the axis of rotation of the housing relative to the second structure. Simultaneous rotation of the housing and member in opposite rotational directions produces arcuate movement of the member first portion and the first structure, about the pivot axis, relative to the second structure.
