US 12,741,579 B2 · Double decker expandable structure

Abstract

An expandable structure can expand to provide a second story and patio over the first story. The expandable structure can be provided as a recreational vehicle, for example. The second story can recess partially into the first story, while the walls of the second story can be formed in two portions that nest with each other, into the upper portion of the first story, when in the retracted state. During expansion, the second story floor can move upward, into its expanded state location, then the roof can lift, unnesting the walls of the second story to form the second story living space. The patio handrails can automatically deploy as the second story is opened. A sliding door, for example, can provide a passage from the second story living space to the patio.
