Abstract
A pivot assembly including a rotating member, a mounting member for supporting the rotating member, and a pivotal interconnection for the members. The interconnection enables rotation about a pivot axis and inhibits translation of the rotating member relative to the mounting member along the pivot axis. There are also structure enabling tilting of the rotating member about a tilt axis transverse to the pivot axis, and gripping elements for inhibiting relative rotation about the pivot axis. The gripping elements increase grip between the adjacent sections when the rotating member is tilted about the tilt axis in a first direction, and decrease grip when the rotating member is tilted about the tilt axis in a second and opposite direction to enable rotation of the rotating member.
