Movable home with retractable structures

An expandable structure, comprising:

• a main structure;
• a front first side frame structure foldable against the main structure in a stowed state and openable to extend outward from the main structure in an expanded state;
• a rear first side frame structure foldable against the main structure in the stowed state and openable to extend outward from the main structure in the expanded state;
• a plurality of front wall panels stored in a stacked arrangement in a front wall panel box in the main structure, each of the plurality of front wall panels movable along tracks to provide a front wall in the front first side frame structure;
• a plurality of rear wall panels stored in a stacked arrangement in a rear wall panel box the main structure, each of the plurality of rear wall panels movable along tracks to provide a rear wall in the rear first side frame structure;
• and
• a plurality of floor panels, stored in a stacked arrangement in a floor panel box in the main structure, each of the plurality of floor panels movable along tracks to provide a floor spanning between the front first side frame structure and the rear first side frame structure when each are in the expanded state, wherein:
• the front wall panel box is located between a front face of the main structure and a front-most interior wall of the main structure;
• the rear wall panel box is located between a rear face of the main structure and a rear-most interior wall of the main structure;
• and
• the floor panel box is located below a floor of the main structure.

• a rear first side frame structure foldable against the main structure in the stowed state and openable to extend outward from the main structure in the expanded state;
• a plurality of front wall panels stored in a stacked arrangement in the main structure, each of the plurality of front wall panels movable along tracks to provide a front wall in the front first side frame structure;
• a plurality of rear wall panels stored in a stacked arrangement in the main structure, each of the plurality of rear wall panels movable along tracks to provide a rear wall in the rear first side frame structure;
• a retractable roof formed from a plurality of roof panels stored in the main structure when in the stowed state and deployable extend between the front first side frame structure and the rear first side frame structure to cover an expanded section formed in the expanded state;
• a plurality of floor panels, stored in a stacked arrangement in the main structure, each of the plurality of floor panels movable along tracks to provide a floor spanning between the front first side frame structure and the rear first side frame structure when each are in the expanded state;
• an outer wall disposed adjacent the main structure, inside each of the folded front and rear first side frame structures when in the stowed state;
• slots formed along each of the front and rear first side frame structures;
• and
• a ball screw rod disposed within each of the slots in each of the front and rear first side frame structures, wherein:
• the ball screw rod extends along the slot in each of the front and rear first side frame structures to terminate within the main structure;
• the ball screw rod is generally linear when the expandable structure is in the expanded state;
• and
• the ball screw rod is angled when the expandable structure is in the stowed state.
