Abstract
Abstract A modular construction unit for ceiling construction and having a unitary frame, ceiling fabric means supported by and incorporated in the frame, suspension attachment means defined by the frame, lighting fixture means attached to the frame and adapted to be supported thereby in position in the ceiling, and air handling means attached to said frame and adapted to be supported thereby when in position in the ceiling and electrical connection means and air handling connection means associated with the lighting fixture means and the air handling means for connection to services within the ceiling, and junction means formed on said frame means around the edges thereof for interfitting engagement with adjacent said units to form a complete ceiling.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
234 words
A modular ceiling construction unit for a ceiling construction of the type in which air handling and electrical supply facilities are concealed in the space between the ceiling and the building structure, said unit having an upper concealed side and a lower visible side, said construction unit comprising; unitary frame means; ceiling fabric means supported and incorporated in said frame means; suspension attachment means on said frame means; lighting fixture means attached to said frame means and supported thereby in position in said ceiling; electrical connection means connected to said lighting fixture means, and adapted to make electrical connection with an adjacent electrical supply within said space; air passage means formed in said construction unit for passage of air therethrough from one said side to the other thereof; air handling means attached to said frame means and supported thereby when said unit is in position in said ceiling and in communication with said air passage means; air handling connection means connected with said air handling means, and adapted to interconnect with air handling facilities adjacent to said unit within said space; junction means formed on said frame means around the edges thereof for interfitting engagement with adjacent said units to form a complete ceiling, and, access haTchway opening means defined in said unit, and closure means therefor whereby to permit access to the upper concealed side of said unit from the lower side thereof.
Claim 2
Dependent Claim
234 words
A modular ceiling construction unit for a ceiling construction of the type in which air handling and electrical supply facilities are concealed in the space between the ceiling and the building structure, said unit having an upper concealed side and a lower visible side, said construction unit comprising; unitary frame means; ceiling fabric means supported and incorporated in said frame means; suspension attachment means on said frame means; lighting fixture means attached to said frame means and supported thereby in position in said ceiling; electrical connection means connected to said lighting fixture means, and adapted to make electrical connection with an adjacent electrical supply within said space; air passage means formed in said construction unit for passage of air therethrough from one said side to the other thereof; air handling means attached to said frame means and supported thereby when said unit is in position in said ceiling and in communication with said air passage means; air handling connection means connected with said air handling means, and adapted to interconnect with air handling facilities adjacent to said unit within said space; junction means formed on said frame means around the edges thereof for interfitting engagement with adjacent said units to form a complete ceiling, and, access haTchway opening means defined in said unit, and closure means therefor whereby to permit access to the upper concealed side of said unit from the lower side thereof.
Claim 3
Dependent Claim
52 words
A modular ceiling construction unit as claimed in claim 1 wherein said frame means defines a recessed channel extending at least partially therearound, and wherein said air passage means includes slotted openings in said frame means opening into said recessed channel, and along at least part of the length of said channel.
Claim 4
Dependent Claim
40 words
A modular ceiling construction unit as claimed in claim 1 including edge flange means for interengagement with adjacent said flange means on adjacent said construction units for mutual interlocking supporting engagement between said units when in position in said ceiling.
Claim 5
Dependent Claim
83 words
A modular ceiling construction unit as claimed in claim 3 wherein said unit defines four sides, and including said edge flange means on all four sides thereof, arranged in pairs, one said pair of edge flange means being offset in a plane relative to the other said pair of edge flange means whereby the plane of one said pair is displaced vertically relative to the plane of the other said pair by an amount equal to about the thickness of said flange means.
Claim 6
Dependent Claim
30 words
A modular ceiling construction unit as claimed in claim 4 wherein said flange means define notched recesses at three corners, and wherein said flange means meet at a fourth corner.
Claim 7
Dependent Claim
34 words
A modular ceiling construction unit as claimed in claim 1 wherein said frame means and said ceiling fabric means are formed in one piece integrally with one another of a single sheet of material.
Claim 8
Dependent Claim
61 words
A modular ceiling construction unit as claimed in claim 1 including wall means traversing said frame side to side thereof, slotted opening means formed in at least some of said wall means, and forming said air passage means, and an air handling chamber, defining said air handling means, attached in registration with said slotted opening means for communication of air therethrough.
Claim 9
Dependent Claim
60 words
A modular ceiling construction unit as claimed in claim 1 including wall means traversing said frame means and defining a space therebetween, means for supporting a light trasnmitting panel member formed on said wall means, and a light transmitting member supported thereby, and said lighting fixture means being attached to said wall means in registration with said light transmitting panel.
Claim 10
Dependent Claim
70 words
A modular ceiling construction unit as claimed in claim 1 including means defining two channels spaced apart from one another and traversing said frame means, and attached thereto in mutually supporting relationship, slotted opening means within said channel means and forming said air passage means, said slotted opening means being recessed within and substantially obscured from view by said channel means, and including air deflector means within said channel means.
