ABSTRACT:
An apparatus (10) includes first and second plates (44and84) extending parallel to each other and movable relative to each other. A locking mechanism (140) prevents movement between the first and second plates (44and84). The locking mechanism (140) has a first position applying a force to urge the first and second plates (44and84) toward each other to prevent movement between the first and second plates. The locking mechanism (140) has a second position to permit relative movement between the first and second plates (44and84). A surface treatment on one of the first and second plates (44and84) and between the first and second plates resists relative movement between the first and second plates when the locking mechanism (140) is in the first position. The surface treatment lubricates relative movement between the first and second plates (44and84) when the locking mechanism (140) is in the second position.
