<p>A ball joint assembly comprising a base member (60), a spherical member (20), a ring of at least three rolling members (40) mounted around the spherical member (30) such that a point on a rolling surface of each of the least three rolling members (40) contacts a point on a first great circle (50) on the surface of the spherical member, the ring of rollers being freely rotatable around the axis of the first great circle, at least two capture rolling members (40), one capture rolling member being mounted such that a rolling surface of the one capture rolling member is in contact with a point on the surface of the spherical member (20) above the plane of the first great circle and another capture rolling member being mounted such that a rolling surface of the other roller member is in contact with a point below the plane of the first great circle.</p> |
