Abstract
Abstract A window system for demountable walls is disclosed which eliminates the necessity of custom-sizing of windows to compensate for variations in floor-to-ceiling spacing. The window system provides jacking means mounted on the lower window frame member which are operable to adjust the height of the window from the floor to compensate for variations in floor-to-ceiling spacing. A floor trim assembly includes cover plates which extend up and over the lower framing member and jacking system to obscure both from view. Such cover plates rest on the floor to provide a uniform height lower window trim that follows the floor line. A baseboard and upper trim system extends uniformly along the window and adjacent wall panels to provide an integrated window and wall system. The side framing members connect to sheet metal wall studs for additional strength and enclose the adjacent stud in instances in which windows are mounted adjacent to each other. The system allows the use of standard size, preglazed windows, but also allows field glazing when required.

Claim 1
Independent Claim
171 words
A demountable partition system extending between a floor and a ceiling, comprising floor and ceiling tracks respectively mounted on said floor and ceiling, studs extending between said tracks, wall panels supported by said tracks and studsk, and a floor-to-ceiling window providing top, side, and bottom framing means, said side framing means connecting with adjacent studs and partially enclosing said adjacent studs, said connection causing said adjacent studs to strengthen said side framing means, said top framing means connected with and being supported by said ceiling track, said bottom framing means including adjusting means for adjusting the height of said window with respect to said floor, and base trim following said floor and removably connected to said bottom framing means, said base trim enclosing and obscuring said adjusting means and accommodating variations in spacing between said bottom framing means and said floor by providing a uniform spacing between said floor and the lower edge of the exposed portion of glass even when said bottom framing means is inclined relative to said floor.
Claim 2
Dependent Claim
171 words
A demountable partition system extending between a floor and a ceiling, comprising floor and ceiling tracks respectively mounted on said floor and ceiling, studs extending between said tracks, wall panels supported by said tracks and studsk, and a floor-to-ceiling window providing top, side, and bottom framing means, said side framing means connecting with adjacent studs and partially enclosing said adjacent studs, said connection causing said adjacent studs to strengthen said side framing means, said top framing means connected with and being supported by said ceiling track, said bottom framing means including adjusting means for adjusting the height of said window with respect to said floor, and base trim following said floor and removably connected to said bottom framing means, said base trim enclosing and obscuring said adjusting means and accommodating variations in spacing between said bottom framing means and said floor by providing a uniform spacing between said floor and the lower edge of the exposed portion of glass even when said bottom framing means is inclined relative to said floor.
Claim 3
Dependent Claim
63 words
A demountable partition system as set forth in claim 1, wherein said ceiling track is a downwardly open channel, and said top framing means is structured to snap into said ceiling track channel and be substantially entirely positioned within said channel, said channel also receiving the upper ends of said panels and providing a uniform trim along both said panels and said window.
Claim 4
Dependent Claim
29 words
A demountable partition system as set forth in claim 2, wherein said base trim includes a baseboard providing a uniform trim extending along both said panels and said window.
Claim 5
Dependent Claim
45 words
A demountable partition system as set forth in claim 1, wherein said connection between said side framing means and said studs is provided by mounting clips mounted at intervals along said studs which provide latching means which connect with associated of said side framing means.
Claim 6
Dependent Claim
210 words
A window system for demountable walls in which said demountable walls include floor and ceiling tracks, and metal studs adapted to extend between said tracks and cooperate therewith to support wall panels, comprising a floor-to-ceiling window, bottom framing means glazed to the lower edge of said window, jacking means mounted on said framing means operable to engage said floor track and adjusting the height of said framing means relative to said floor track through a range of adjustments, and base trim means adapted to rest on the floor and removably connect to said bottom framing means in any position within said range of adjustment, said base trim means extending over said bottom framing means and said jacking means to a position adjacent said window to enclose and obscure said bottom framing means along with said jacking means, said base trim means including a cover member adapted to rest on said floor and enclose and obscure the connection between said bottom framing means and said base trim means, said base trim means providing a uniform width along the length thereof so that when said window is installed the lower edge thereof appears to be uniformly spaced from said floor even when said bottom framing means is inclined relative to said floor.
Claim 7
Dependent Claim
210 words
A window system for demountable walls in which said demountable walls include floor and ceiling tracks, and metal studs adapted to extend between said tracks and cooperate therewith to support wall panels, comprising a floor-to-ceiling window, bottom framing means glazed to the lower edge of said window, jacking means mounted on said framing means operable to engage said floor track and adjusting the height of said framing means relative to said floor track through a range of adjustments, and base trim means adapted to rest on the floor and removably connect to said bottom framing means in any position within said range of adjustment, said base trim means extending over said bottom framing means and said jacking means to a position adjacent said window to enclose and obscure said bottom framing means along with said jacking means, said base trim means including a cover member adapted to rest on said floor and enclose and obscure the connection between said bottom framing means and said base trim means, said base trim means providing a uniform width along the length thereof so that when said window is installed the lower edge thereof appears to be uniformly spaced from said floor even when said bottom framing means is inclined relative to said floor.
