Armboard assembly

摘要

The illustrative armboard assembly includes a lockable first joint coupling an armboard to a support arm, a lockable second joint coupling the support arm to a mounting post and a lockable third joint coupling the mounting post to a mounting rail. The first joint is configured to permit movement of the armboard along the support arm and configured to permit movement of the armboard relative to the support arm about a first plurality of axes. The second joint is configured to permit movement of the support arm relative to the mounting post about a second plurality of axes. The third joint is configured to position the mounting post in a selected vertical position relative to the mounting rail and in a selected longitudinal position along the mounting rail.
