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 bag 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.
Claims20
A luggage apparatus comprising a bag frame and sub-frame, the luggage apparatus 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, the sub-frame and bag frame geometry defined by only three pivot axes, rotation about the three pivot axes moving the bag frame between the upright mode and tilt modes, wherein the three pivot axes define a generally triangular shape formed by the pivot axes, which are in an approximately right angle shape when the luggage apparatus is in an upright mode and, the triangular shape formed by the pivot axes has an approximately acute angle shape when the luggage apparatus is in a tilt mode.
A luggage apparatus comprising a bag frame and sub-frame, the luggage apparatus 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, the sub-frame and bag frame geometry defined by only three pivot axes, rotation about the three pivot axes moving the bag frame between the upright mode and tilt modes;
- and
- 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, the rear member(s) being 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.
