<p>A wheeled luggage case that is tilted for towing is provided with a retractable and, optionally, telescoping handle ( 4 ) assembly that is withdrawn from the interior of the case to an extended vertical position at the intersection of the top and rear walls, from which it is angularly rotated by the user to a position that minimizes the vertical force that is required to support the hand grip to comfortably tow the luggage. Preferred angular displacements for a wide range of users and loads positioned in and on the luggage case have been found to be at about 17° and 35° from the vertical position.</p> |
