Movable partition wall

A demountable partition assembly comprising

• a. a ceiling runner rigidly attached to an upper supporting surface, said ceiling runner including a base, a pair of downwardly extending outer legs, and a pair of outwardly and downwardly inclined inner legs, each outer leg and adjacent inner leg defining a space therebetween;
• b. a pair of wall panels at either side of said partition assembly and forming the exposed wall surfaces thereof, the upper end of each panel being removably positioned in said ceiling runner, said panels being spaced and thereby providing a substantially open area therebetween for accommodating wiring, piping and the like;
• c. a floor runner comprising a base, a pair of outer legs, and a pair of outwardly and upwardly inclined inner legs, the upper portion of each outer leg and the adjacent inner leg defining a space therebetween, said ceiling and floor runners being spaced so as to exceed in dimension the vertical dimension of said wall panels whereby said panels when installed can first be raised upwardly in said ceiling runner and thereafter lowered so that the bottom edges of said panels engage said base of said floor runner,
• d. means for supporting and laterally stabilizing said floor runner and thus said partition wall from a supporting surface, said supporting means serving as the sole support for said partition assembly, and
• e. a door and mounting means therefor in said partition assembly, said mounting means including a door header having projecting portions received in said spaces between said outer and inner legs of said ceiling runner, and means for securing said header to said ceiling runner, and door jamb means at either side of the door opening rigidly interconnected to the adjoining wall panels.

• d. means for supporting and laterally stabilizing said floor runner and thus said partition wall from a supporting surface, said supporting means serving as the sole support for said partition assembly, and
• e. a window and mounting frame therefor disposed along said wall, said mounting frame including a window header having projecting portions received in the spaces between said outer and inner legs of said ceiling runner, and means for securing said window header to said ceiling runner, a window base formed with projections extending into the spaces defined by said outer and inner legs of said floor runner, and means for securing said window base to said floor runner, and window jamb members disposed at either side of the window opening, said window jamb members being rigidly interconnected to said adjoining wall panels.

A demountable partition assembly comprising

• a. a celing runner rigidly attached to the upper supporting surface for the partition assembly, said ceiling runner being formed with a base and downwardly extending outer legs;
• b. a pair of wall panels at either side of said partition assembly and forming the exposed wall surfaces thereof, said panels being spaced and thereby providing a substantially open area therebetween for accommodating wiring, piping and the like, each of said panels being formed with grooves in the top and bottom edges thereof, said outer legs of said ceiling runner extending into said grooves in the top edges of said panels when the latter are mounted, and
• c. a floor runner formed with a generally horizontal base and outer legs extending upwardly and downwardly at the outer edges of said base, said outer legs of said floor runner extending into the grooves in the bottom edges of said panels when the latter are mounted, the bases of said ceiling and floor runners being spaced so as to exceed in dimension the vertical dimension of said wall panels whereby said panels when installed can first be raised upwardly by virtue of said slots toward the base of said ceiling runner and thereafter lowered so that the bottom edges of said panels engage said base of said floor runner, and
• d. means for supporting and laterally stabilizing said floor runner and thus said partition wall from a supporting surface, said supporting means serving as the sole support for said partition assembly, said means for supporting and laterally stabilizing said floor runner and thus said partition walls comprising a leveling block disposed within the downwardly extending outer legs of said floor runner, and a floor strip positioned within said outer legs below said leveling block, said floor strip being spaced from the supporting surface for the partition assembly by nail means extending downwardly through said floor strip into engagement with said supporting surface, whereby said floor strip and thus said partition assembly can be installed over carpet without significant damage thereto, downwardly extending portions of said outer legs of said floor runner terminating adjacent the upper surface of the carpet whereby said outer legs function as finish trim members.
