Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
199 words
A suspended ceiling structure closing a ceiling void in a building which comprises a plurality of coffered ceiling modules wherein each ceiling module is adapted to be selectively removably fitted with a lighting fixture whereby the lighting arrangement in said ceiling structure may be varied to provide lighting in some such modules, and no lighting in other such modules, each said module comprising; upwardly directed side walls, and a horizontal top wall, formed of sound attenuating material, and forming a hollow box-like structure having a downwardly directed open side; suspension means on each of said modules whereby each said module is independently suspended from above; ceiling panel support means extending outwardly along the lower edges of said box-like structure whereby ceiling panels are supported between adjacent modules; unobstructed opening means in said top wall of predetermined length and width communicating with said ceiling void for removably receiving a said lighting fixture therein from below; and said ceiling structure further comprising lighting fixtures of predetermined length. and width, dimensioned to fit within said opening means from below, any other of said opening means being closed by removable panel means whereby those modules without lighting fixtures will present a finished appearance.
Claim 2
Dependent Claim
