Extendable and retractable luggage

Telescoping luggage adapted for travel on an aircraft, the telescoping luggage comprising:

• a housing including an opening defining an inner perimeter which forms a first compartment therein for storage, the housing including an open lower end;
• and
• a module movably connected to the housing, the module including an opening therethrough which defines an inner perimeter which forms a second compartment therein for storage, the first compartment and the second compartment in moveable cooperation to expand and retract, the first compartment configured to permit at least a portion of the module to fit within the inner perimeter and a portion of the first compartment of the housing when the module is in a retracted position, the module configured to move to within the housing to extend outward away from the portion of the housing in an extended position,
• wherein the housing and the module are in an axial alignment, such that the telescoping extended position and the retracted position of the module within the housing is maintained in the axial alignment,
• wherein a portion of the module and a portion of the housing overlap each other and connect together when in the extended position, and when the module is retracted within the portion of the housing, a frame at a lower end of the module is positioned against a rim of the housing to form the retracted position,
• wherein the housing and the module are each formed from a material that forms a solid hard-shell structure that resists deformation,
• wherein the portion of the module includes a first margin and the portion of the housing includes a second margin, and the first margin and the second margin overlap each other and connect together in the extended position, and wherein when the first margin and the second margin are released from their connection, the module is moved into the housing, and the second margin of the housing overlaps a third margin of the module and abuts the frame to provide the retracted position,
• wherein the first margin is positioned near to a rim of the lower end of the housing, wherein the second margin is positioned near to a rim of the upper end of the module, and wherein the third margin is positioned near the frame of the module, and
• wherein the second margin of the housing and the frame at a lower end of the module each include a portion of a clasp assembly that, when the second margin of the housing overlaps the third margin of the module and abuts the frame of the module, each portion of the clasp assembly is positioned to connect together to hold the housing and module in the retracted position.
