A retractable handle assembly of luggage comprises a single handle rod extended upward from a center at a joining edge of a top and a rear of luggage and having an upper portion and a lower portion connected to the rear; and a handle grip extended at a predetermined range of angle about a horizontal plane from a top of the handle rod toward a side of the luggage being perpendicular to the top or the rear of luggage in a stand-up position. An orientation of a hand holding the handle grip is parallel to a moving direction of the luggage being towed for facilitating an exertion of user's force thereon, thereby lowering a center of gravity of luggage for saving labor.

Single handle rod based retractable handle assembly for wheeled luggage

A handle assembly having a single handle rod of wheeled luggage is provided. The handle grip is extended toward and proximate either side of luggage for ease of holding. Also, there is no interference of user's body with wheel while towing luggage. Moreover, the handle grip is capable of being disposed either parallel or perpendicular with respect to a straight line between wheels of the luggage by rotating either clockwise or counterclockwise for ease of being gripped by either hand which tows the luggage.
