Abstract
Abstract A building construction and method for transforming a large open space into a plurality of smaller rooms. A portable room module is folded into an essentially planar configuration for storage. The module is supported upon retractable wheels and accommodates movement from a storage location to a predetermined utility location within a larger room. In the utility location, the portable room module is expanded to room size and an elevated ceiling unit is lowered so as to rest upon the room module and form a ceiling unit therefor. Partially collapsible insulating material is situated at joints of the wall portions of the room module and also at the top and bottom of the wall portions so as to form an acoustic and hermetic seal when the module is unfolded and when the elevated ceiling unit comes to rest upon the wall panels. The weight of the ceiling unit simultaneously (a) displaces the wall panel vertically downward over the retractable wheels to secure the position of the wall panels and (b) compresses the insulating material at both the top and bottom of the wall panel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
A building structure comprising in combination: an assembly of generally vertically-oriented wall panels together forming the four walls of a room and serially joined together to accommodate (a) folding at least one of the wall panels upon the other into a storage configuration and (b) unfolding the wall panels into an enclosed room configuration, the assembly of wall panels comprising means facilitating displacement of the entire assembly from place to place at least when in the storage configuration; a ceiling unit suspended above the wall panel, the ceiling unit comprising means for selectively lowering at least part of the weight of the ceiling unit upon the unfolded assembly wall panels; and means interposed above and below the wall panels for forming a seal when the weight of the ceiling unit is brought to rest upon the wall panel assembly.
Claim 2
Dependent Claim
139 words
A building structure comprising in combination: an assembly of generally vertically-oriented wall panels together forming the four walls of a room and serially joined together to accommodate (a) folding at least one of the wall panels upon the other into a storage configuration and (b) unfolding the wall panels into an enclosed room configuration, the assembly of wall panels comprising means facilitating displacement of the entire assembly from place to place at least when in the storage configuration; a ceiling unit suspended above the wall panel, the ceiling unit comprising means for selectively lowering at least part of the weight of the ceiling unit upon the unfolded assembly wall panels; and means interposed above and below the wall panels for forming a seal when the weight of the ceiling unit is brought to rest upon the wall panel assembly.
Claim 3
Dependent Claim
58 words
A building structure as defined in claim 1 further comprising downwardly biased displaceable wheels providing facile movement of the wall panels acrossed floor surface, the displaceable wheels being selectively telescoped into the interior of the wall panel when the wall panel is downwardly displaced in response to the weight of the ceiling unit upon the wall panel assembly.
Claim 4
Dependent Claim
81 words
A building structure as defined in claim 1 wherein said assembly of wall panels comprises front and rear wall panels and side wall panels, said side wall panels being hinged in the vertical plane to permit the side wall panels to fold inwardly between the front and rear panels as the front and rear panels are brought together so that both front and rear wall panels and side wall panels, in the folded configuration, are each essentially parallel to the next.
Claim 5
Dependent Claim
37 words
A building structure as defined in claim 1 wherein said ceiling unit comprises means for vertically displacing the ceiling unit between a first elevated position and a second lowered position, engaging the unfolded assembly of wall panels.
Claim 6
Dependent Claim
37 words
A building structure as defined in claim 4 wherein said ceiling unit comprises an air delivery opening and a light source which, when the ceiling unit is in the lower, wall panel-engaging position, delivers air and light.
Claim 7
Dependent Claim
40 words
A building structure as defined in claim 1 wherein said seal forming means comprises a generally flexible tubular insulator having an axially aligned inwardly directed projection which prevents total collapse of the insulator when the insulator is compressed under pressure.
Claim 8
Dependent Claim
33 words
A building structure as defined in claim 1 further comprising displaceable wheel means spaced laterally away from the center of gravity of the at least partially folded assembly for stabilizing the folded assembly.
Claim 9
Dependent Claim
48 words
A building structure as defined in claim 7 wherein said means comprises an outwardly projecting leg and associated caster which, in a first position, stabilizes the folded assembly and, in a second position, is displaced into a plane essentially parallel with at least one of the wall panels.
Claim 10
Dependent Claim
37 words
A building structure as defined in claim 7 wherein said means comprises a spacing bar for laterally spacing at least two of the wall panels and associated displaceable wheels to lend stability to the partially folded assembly.
