Abstract
An armrest adjusting mechanism is disclosed which includes a base plate mountable to an article of construction machinery and a first working plate movable relative to the base plate. First and second shafts are mounted to the first working plate. The first shaft is guided by first and second spherical bearings fixedly mounted to the base plate. The second shaft is guided by a third spherical bearing adjustably mounted to the base plate. The third spherical bearing is attached to a third shaft which is disposed normal to the first and second shafts. A cylindrical bearing guides the third shaft as it moves in response to misalignment between the first and second shafts. In a similar manner, fourth and fifth shafts are mounted to the first working plate. The fourth shaft is guided by fourth and fifth spherical bearings fixedly mounted to a second working plate. The fifth shaft is guided by a sixth spherical bearing adjustably mounted to the second working plate. The sixth spherical bearing is attached to a sixth shaft which is disposed normal to the fourth and fifth shafts. A second cylindrical bearing guides the sixth shaft as it moves in response to misalignment between the fourth and fifth shafts.
