摘要
A luggage apparatus and method is described herein that introduce a separate wheeled sub-frame that mounts on the base of a luggage apparatus and which allows for dual mode use between an upright mode and a tilt mode. The geometry of the relationship between the bag frame and sub-frame of the luggage apparatus urges the beg to tilt and return upright. The luggage apparatus is securely supported about the sub-frame in both modes with a changing centre of gravity and can be pushed or pulled in either mode.
