Abstract
An improved expandable tote bag has an upper storage unit and a contractible central unit that is mounted above a lower storage base unit. The base unit includes a support assembly that can mount wheel assemblies for enabling the traveler to pull the luggage across the support surface. The upper storage unit and central unit can be pivoted to one side of the lower base unit to enable full access to items stored in the base unit.
Claims9
An expandable luggage bag comprising:
- a hollow base unit including a relatively rigid support assembly and a plurality of wheel assemblies mounted on the support assembly to enable operator transportation of the bag, the base unit including an integrally-molded shell member having a planar surface and a side flange;
- a central unit including a flexible cover member extending across the hollow base unit, thereby defining a bottom surface, and extending around the central unit, thereby defining a peripheral side of the central unit, the flexible cover member including a first zipper assembly vertically displaced around the peripheral side, such that the first zipper assembly, when opened, enables an expansion of the flexible cover member, increasing a storage capacity of the central unit and, when closed, enables a retraction of the flexible cover member with the peripheral side of the central unit folding inward, decreasing the storage capacity of the central unit;
- a storage unit connected to the central unit and integral with the flexible cover member, the flexible cover member having a closable opening extending across an upper portion of the storage unit;
- means for pivoting the central unit and storage unit to one side of the base unit to expose an opening in the hollow base unit for storage purposes;
- and
- a retainer member mounted on the shell member and extending upward to the central unit to form a semirigid internal side wall to the base unit to maintain its shape for storage purposes.

An expandable, vertically upright luggage bag comprising:
- a hollow base unit including a relatively rigid support assembly, a plurality of wheel assemblies mounted on the support assembly to enable operator transportation of the bag, and a relatively-sized side wall;
- a central unit including a flexible cover member extending across the hollow base unit, thereby defining a bottom surface and extending around the central unit, thereby defining a peripheral side of the central unit, the flexible cover member including a first zipper assembly vertically displaced around the peripheral side, such that the first zipper assembly, when opened, enables an expansion of the flexible cover member, increasing a storage capacity of the central unit and, when closed, enables a retraction of the flexible cover member with the peripheral side of the central unit folding inward, decreasing the storage capacity of the central unit, the bottom surface including a storage pouch of a dimension to retain a pair of shoes;
- a storage unit connected to the central unit and integral with the flexible cover member, the flexible cover member having a closable opening extending across an upper portion of the storage unit, the storage unit being larger than either the base unit or the central unit;
- and
- means for pivoting the central unit and storage unit to one side of the base unit to expose an opening in the hollow base unit for storage purposes, including a second zipper assembly extending between the base unit and the central unit.

- a storage unit connected to the central unit and integral with the flexible cover member, the flexible cover member having a closable opening extending across an upper portion of the storage unit;
- means for pivoting the central unit and storage unit to one side of the base unit to expose an opening in the hollow base unit for storage purposes, including a second zipper assembly extending between the base unit and the central unit;
- and
- a retainer member mounted on the shell member and extending upward to the central unit to form a semirigid internal side wall to the base unit.
