  • Patent number: 6889947
    Abstract: Article holder (10) comprises seat member (12) shaped to receive article, gate member (20) hingedly coupled to seat member (12), gate member (20) shaped to cooperate with seat member (12) in closed position so as to grasp article, rotatable handle (22) connected with gate member (20) so as to move gate member (20) between open position and closed position as handle (22) is rotated. Handle (22) has locking means (34, 36, 37, 38) for locking handle (22) when handle (22) is rotated to lock position, wherein handle (22) must be over rotated further than position where gate member (20) is closed to be positioned in lock position. Over rotation causes compressive gripping force to gate member (20) such that gate member (20) continues to grasp article while handle (22) is in lock position.
