Abstract
Abstract A mobile home having wall members hingedly mounted to the structure for allowing the members to assume an outwardly extending angularly oriented position. Floor extensions are moved for connection with wall members to form additional living space. Telescoping braces are connected to the lower wall members and engage the ground thereby stabilizing the structure.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
An expandable building structure comprising: a fixed support frame having side walls and transverse end walls; hinge means attached to the side walls of the frame; at least one foldable roof section mounted to the hinge means for pivotally moving about a horizontal axis, fixed relative to the frame, from a horizontal position with respect to the frame to an angularly oriented position with respect to the frame; at least one foldable vertical side wall section mounted to hinge means for pivotally moving about a horizontal axis, fixed relative to the frame, from a vertical position with respect to the frame to a downwardly coextensive angularly oriented position with respect to the roof section; a main floor attached to the frame; and floor extension means connected to the main floor by floor mounted hinge means for pivotally moving about a horizontal axis, fixed relative to the frame, from juxtaposition with the main floor to a laterally coplanar extended position with respect to the main floor; whereby the sidewall section and the roof section form an inclined sidewall of an A-frame structure.
