Abstract
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.
Claims10
A luggage apparatus comprising:
- a bag frame;
- and
- a sub-frame, the sub-frame located below the bag frame;
- wherein the luggage apparatus is configured to move between an upright mode with the bag frame in a substantially upright orientation and a tilt mode with the bag frame on an angle relative to a vertical plane, wherein:
- in upright mode, the luggage apparatus center of gravity is generally inside a volume defined by the bag frame and wherein, in tilt mode, the luggage apparatus center of gravity is generally outside a volume defined by the bag frame, and,
- when the luggage apparatus is moved from an upright mode to a tilt mode, the luggage apparatus center of gravity moves backwards and when the luggage apparatus moves from a tilt mode to an upright mode, the center of gravity moves forwards;
- wherein the sub-frame attaches to the rear of the bag frame via at least one rear member that bridges the sub-frame to the rear of the bag frame;
- and
- wherein the rear member(s) are located flush with the bag frame when the luggage apparatus is in upright mode and the rear member(s) pivoting out from the bag frame when in tilt mode.
