The outer ring is mounted on the frame for rotation about a first axis extending generally diametrically of the outer ring. The intermediate ring is mounted on the outer ring for rotation relative to the outer ring about a second axis extending generally diametrically of the intermediate ring. The inner ring is mounted on the intermediate ring for rotation relative to the intermediate ring about a third axis of rotation extending generally diametrically of the inner ring. Two of the axes of rotation of the rings are oriented obliquely with respect to the other of said axes of rotation.
