A lever system deploys a pinion gear that engages a pinion gear receiving portion.
A handle is attached to the pinion gear to rotate the pinion gear between a retain
position and a release position. The pinion gear receiving portion is attached
to a first object and the pinion gear is pivotably mounted to a second object that
may be moved with respect to the first object. The design of the pinion gear receiving
portion and the pinion gear ensure linear travel of the second object as the pinion
gear is rotated between the retain position and the release position. Additionally,
the pinion gear and the receiving portion include contours that prevent relative
linear motion in all directions.
