Abstract: The present invention provides an expansion system for luggage comprising an upper frame, a lower frame, an expandable section attached between the upper and lower frames, and expansion mechanisms. Each expansion mechanism comprises an upper member attached to the upper frame, a lower member attached to the lower frame and two arms, wherein each arm is pivotally connected to the upper member at one end and is pivotally and slideably connected to the lower member at the other end.

Abstract: A stabilizing mechanism is provided in an expandable travel bag to maintain the bag in the expanded condition. The stabilizer comprises a tongue secured to one of a pair of coincident frame members which mates with a receiver secured to the other frame member. The facing edges of the coincident frame members are joined by an expansion ring which is extended when the tongue is secured in the receiver and collapsed when the tongue and receiver are disconnected.

Abstract: Zipper closures, luggage locks attached to zipper closures and retractable handles on travel bags are protected by covers which conceal such luggage hardware when in the closed or retracted position. The protective covers are in the form of rectangular flaps or the like which have one edge secured to the bag and aligned so that the flap is extendable over and attached or attachable to the bag on the opposite side of the zipper or handle so that the luggage hardware is covered and protected during transit.

Abstract: A rigid frame travel bag equipped with wheels and a retractable handle is formed with a rigid frame assembly which includes a front panel, a rear panel and a shell in the form of a C-shaped bottom panel. The rigid frame members are constructed of extruded plastic material such as acrylonitrile-butadiene-styrene copolymer (ABS) or polyvinyl chloride (PVC). For increased strength and reduced weight, each panel is formed with longitudinally extending cells defined by longitudinally extending ribs. The front and rear panels are attached to the C-shaped bottom panel by integrally formed connecting flanges which extend in overlapping engagement with the inside surfaces of end panel portions extending from the bottom panel. The front and rear panels are also attached to and stabilized on one of the end panel portions by wheel assembly support plates.

Abstract: Wheeled luggage apparatus having a pair of independent wheel assemblies is formed with a frame having first, second, third and fourth sidewalls. A first notch (which extends from edge to interior side surfaces of the first and second sidewalls) and a second notch (which extends from edge to interior side surfaces of the second and third sidewalls) are formed in the frame. First and second wheel assemblies, each fully independent from the other, are mounted to the frame of the wheeled luggage apparatus. Each of the independent wheel assemblies is comprised of first and second subassemblies. Each of the first subassemblies are comprised of a central wheel well and first and second flanges while each of the second subassemblies are comprised of a central portion and first and second flanges.
