c) an interior of the front section including two support brackets, a first support bracket bridging a bottom shell panel and a middle shell panel, and a second support bracket bridging the middle and a top shell panel, the first support bracket and the second support bracket each comprising a channel component, a glide component and a spring plunger, wherein the bottom shell panel is slidably-connected to the middle shell panel and the middle shell panel is slidable-connected to the top shell panel,
wherein the expandable frame is configured to expand and collapse the item of luggage to a minimum of two vertical positions.
12. The expandable and collapsible suitcase of claim 11 , wherein the two telescoping members each include a movable locking mechanism that is configured to lock and release at the three vertical positions, and wherein at least one of the horizontal supports includes a release point for the movable locking mechanism.
13. The expandable and collapsible luggage item of claim 11 , wherein at a maximum vertical position, a portion of a top shell panel of the front section overlaps with a portion of a middle shell panel of the front section, a portion of a top shell panel of the back section overlaps with a portion of a middle shell panel of the back section, a portion of a bottom shell panel of the front section overlaps with a portion of a middle shell panel of the front section, and a portion of a bottom shell panel of the back section overlaps with a portion of a middle shell panel of the back section.
14. The expandable and collapsible luggage item of claim 11 , wherein at a minimal vertical position, at least portions of all of the three slidably-connected shell panels of the front section overlap and at least portions of all of the three slidably-connected shell panels of the back section overlap.
15. The expandable and collapsible luggage item of claim 14 , wherein at the minimum vertical position a portion of a top shell panel of the front section is nested between a portion of a bottom shell panel and a middle shell panel of the front section, and wherein a portion of the top shell panel of the back section is nested between a portion of a bottom shell panel and a middle shell panel of the back section.
