Abstract
Abstract A suspended ceiling for a building which includes a plurality of modules, each including a frame, the frame being arranged in a common horizontally extending plane. At least certain of the frame carry elongated lamp fixtures which are supported by the fixed ceiling and above the frame sections. Sound absorbing light-reflecting panels have their lower ends carried by the said certain frames. These panels extend upwardly and terminate substantially at the light emitting surface of the lamp fixtures. Two of these panels are elongated, and, depending upon the width of the light fixtures, relative to the width of the module, the two panels are disposed at angles between approximately 158* and 163* with respect to the plane of the light emitting surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
A suspended ceiling for a building, comprising in combination: A. a frame; B. means for supporting the frame within the building; C. a unitary structure including: 1. a lighting fixture having: a. means forming a horizontally extending, light-emitting surface, b. panel-supporting means on opposite sides of the means (C) (1) a); 2. a support for removably supporting the unitary structure on the frame; D. a plurality of removable acoustic, light-reflecting panels, each having one edge supported by the frame and the other edge supported by the means (C) (1) (a).
Claim 2
Dependent Claim

Claim 3
Dependent Claim
38 words
a support for removably supporting the unitary structure on the frame; D. a plurality of removable acoustic, light-reflecting panels, each having one edge supported by the frame and the other edge supported by the means (C) (1) (a).
Claim 4
Dependent Claim
38 words
a support for removably supporting the unitary structure on the frame; D. a plurality of removable acoustic, light-reflecting panels, each having one edge supported by the frame and the other edge supported by the means (C) (1) (a).
Claim 5
Dependent Claim
63 words
A suspended ceiling as defined in claim 1 characterized in that the light-emitting surface and the panel-supporting means are disposed above the bottom of the frame and that the first mentioned edges of the panels are disposed at a lower level than the second mentioned edges, whereby the panels are disposed at obtuse angles with respect to the plane of the light-emitting surface.
Claim 6
Dependent Claim
28 words
A suspended ceiling as defined in claim 2, characterized in that the second mentioned edges of the panels terminate substantially at the same level as the light-emitting surface.
Claim 7
Dependent Claim
39 words
A suspended ceiling as defined in claim 1, characterized in that the frame includes: A. 1 two parallelly disposed runners; and further characterized in that the support (C) (2) of the unitary structure is removably supported by the runners.
Claim 8
Dependent Claim
40 words
A suspended ceiling as defined in claim 4, characterized in that the support (C) (2) of the unitary structure comprises at least one runner disposed transversely of the first mentioned runners and in notched relationship with the first mentioned runners.
Claim 9
Dependent Claim
128 words
A suspended ceiling as defined in claim 1, characterized in that the frame includes: A. 1 a pair of parallelly disposed runners, said runners extending horizontally and in coextensive relationship, 2 a second pair of parallelly disposed runners, said latter pair of runners extending horizontally and in coextensive relationship with the first mentioned runners, said second pair of runners with the first mentioned pair, 3 means connecting the second pair of runners with the first mentioned pairs, 4 a third pair of parallelly disposed runners, said latter pair of runners extending horizontally and transversely with respect to and supportEd by the second pair of runners; and further characterized in that the support (C) (2) of the unitary structure is removably supported by the first mentioned pair of runners.
Claim 10
Dependent Claim
143 words
A suspended ceiling as defined in claim 1, characterized in that the frame includes: A. 1 a pair of parallelly disposed runners, said runners extending horizontally and in coextensive relationship, 2 a second pair of parallelly disposed runners, said latter pair of runners extending horizontally and in coextensive relationship with the first mentioned runners, said second pair of runners being disposed below the first mentioned pair, 3 means connecting the second pair of runners with the first mentioned pairs, 4 a third pair of parallelly disposed runners, said latter pair of runners extending horizontally and transversely with respect to and supported by the second pair of runners; and further characterized in that the support (C) (2) of the unitary structure comprises a pair of runners for supporting the unitary structure, said latter pair of runners being disposed transversely of the first mentioned runners.
Claim 11
Dependent Claim
26 words
A suspended ceiling as defined in claim 6, characterized in that the first mentioned edges of the panels are removably supported by the third mentioned runners.
Claim 12
Dependent Claim
28 words
A suspended ceiling as defined in claim 8, characterized in that the panel supporting means (C) (1) (b) lie in substantially the same plane as the light-emitting surface.
