Abstract
An expandable home structure can expand outward from at least one side thereof to expand the living space once the home is delivered to a desired location. The expansion process includes raising two roof panels from a side edge of its main structure, where the roof panels follow a track so that an outer one of the two roof panels can, once fully raised, slide outward along front and rear walls of the expansion section so that the roof panels form a box gable roof structure over the expansion section.
Claims18
An expandable home comprising:
- a main section defining the expandable home in a folded configuration;
- front and rear expansion walls pivotable from a first side of the main section to form front and rear expansion walls of an expansion section when the expandable home is in an expanded configuration;
- and
- a roof structure disposed within the main section, adjacent the first side, when the expandable home is in the folded configuration, wherein:
- the roof structure is raisable upward through a roof portion of the main section when the expandable home is in the expanded configuration;
- the roof structure includes an inside roof panel and an outside roof panel, pivotably attached to each other along upper edges thereof;
- the outer roof panel is slidable along the front and rear expansion walls to form a box gable roof structure over the expansion section;
- a track formed in the front and rear expansion walls, wherein the outside roof panel is movable along the track to move into the expanded configuration;
- and
- inside and outside channels formed along an interior surface of each of a front wall and a rear wall of the main section, wherein the inside roof panel moves along the inside channel and the outside roof panel moves along the outside channel when the roof structure is raised out of the roof portion of the main section.

An expandable home comprising:
- a main section defining the expandable home in a folded configuration;
- front and rear expansion walls pivotable from a first side of the main section to form the front and rear expansion walls of an expansion section when the expandable home is in an expanded configuration;
- a track formed horizontally in the front and rear expansion walls;
- inside and outside channels formed along an interior surface of each of a front wall and a rear wall of the main section, wherein an inside roof panel moves along the inside channel and an outside roof panel moves along the outside channel when a roof structure is raised out of a roof portion of the main section;
- and
- the roof structure disposed within the main section, adjacent the first side, when the expandable home is in the folded configuration, wherein:
- the roof structure includes the inside roof panel and the outside roof panel, pivotably attached to each other along upper edges thereof;
- the inside roof panel is movable along the inside channel and the outside roof panel is movable along the outside channel to cause the roof structure to move upward through the roof portion of the main section when the expandable home is moved into the expanded configuration;
- the inside and outside channels are generally parallel with each other at a lower portion thereof;
- the outside channel angles away from the inside channel at an upper portion thereof;
- the inside channel terminates at a maximum height adjacent a top edge of the front and rear walls of the main section;
- the outside channel terminates at the maximum height at an access opening formed in the outer edge of the front and rear walls of the main section;
- and
- the access opening communicates with the track to permit the outside roof panel to move from the outside channel to the track.
