Abstract
A first biasing element is positioned between an opening unit and a first frame for urging the opening unit downward. A lateral pivot combines the first biasing element to the first frame to allow for lateral movement in a horizontal plane of the opening unit. A first resilient device is positioned between the closing unit and the first frame to allow for lateral movement about a vertical axis of the closing unit and to urge the closing unit back to a neutral position. A second resilient device is positioned between the closing unit and the first frame to allow for vertical movement about a horizontal axis and to urge the closing unit back to a neutral position.
