Abstract
Abstract A ceiling assembly is provided wherein a support lattice defining a plurality of rectangular openings is suspended in a horizontal attitude below the roof of the building. A plurality of elongated sheets of ceiling material rest upon and are supported by the support lattice and each sheet extends across a plurality of the rectangular openings. The lattice is supported by wires suspended from the roof structure of the building, with the wires connected at points on the lattice arranged in rows across the lattice, and the sheets of material are placed upon the lattice in rolls and the rolls are unrolled between the suspension wires of the lattice.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
212 words
In a suspended ceiling assembly, a support lattice disposed in an approximately horizontal attitude comprising a plurality of first support bar members extending parallel to one another and equally spaced from one another and a plurality of second support bar members extending parallel to one another and equally spaced from one another and extending at right angles with respect to said first support bar members and defining with said first support bar members a plurality of rectangular openings, a plurality of sheets of elongated ceiling material supported by said support lattice, said sheets of ceiling material being oriented with their long dimensions extending approximately parallel to said first support bar members, said sheets of material being of a width sufficient to span the space between adjacent ones of said first support bar members and of a length sufficient to extend across several ones of said second support bar members so that the rectangular openings between said first and second support bar members are closed by said sheets of ceiling material, holes defined in both said first and second support bar members at their intersections with one another, and suspension means connected to said first and second support bar members at their holes for suspending the ceiling assembly from above the support lattice.
Claim 2
Dependent Claim
212 words
In a suspended ceiling assembly, a support lattice disposed in an approximately horizontal attitude comprising a plurality of first support bar members extending parallel to one another and equally spaced from one another and a plurality of second support bar members extending parallel to one another and equally spaced from one another and extending at right angles with respect to said first support bar members and defining with said first support bar members a plurality of rectangular openings, a plurality of sheets of elongated ceiling material supported by said support lattice, said sheets of ceiling material being oriented with their long dimensions extending approximately parallel to said first support bar members, said sheets of material being of a width sufficient to span the space between adjacent ones of said first support bar members and of a length sufficient to extend across several ones of said second support bar members so that the rectangular openings between said first and second support bar members are closed by said sheets of ceiling material, holes defined in both said first and second support bar members at their intersections with one another, and suspension means connected to said first and second support bar members at their holes for suspending the ceiling assembly from above the support lattice.
Claim 3
Dependent Claim
22 words
The suspended ceiling assembly of claim 1 and wherein said first and second support bar members comprise elongated metal straps under tension.
Claim 4
Dependent Claim
24 words
The suspended ceiling assembly of claim 1 and wherein said second support bar members cross over and rest upon said first support bar members.
Claim 5
Independent Claim
167 words
A method of forming a suspended ceiling in a building or the like comprising the steps of forming a support lattice from a supply of flat strap material defining holes at equally spaced intervals along its length by positioning a first plurality of lengths of strap material in spaced parallel relationship with respect to one another and a second plurality of lengths of strap material in spaced parallel relationship with respect to one another and in overlying intersecting relationship with respect to the first plurality of lengths of strap material with the holes of the first and second pluralities of lengths of strap material located at the overlying intersecting portions of the lengths of strap material, inserting connectors through the holes of the first and second pluralities of lengths of strap material at the intersections of the lengths of strap material, and placing rolls of ceiling material on the support lattice and unrolling the rolls of ceiling material across the support lattice between the rows of connectors.
Claim 6
Independent Claim
167 words
A method of forming a suspended ceiling in a building or the like comprising the steps of forming a support lattice from a supply of flat strap material defining holes at equally spaced intervals along its length by positioning a first plurality of lengths of strap material in spaced parallel relationship with respect to one another and a second plurality of lengths of strap material in spaced parallel relationship with respect to one another and in overlying intersecting relationship with respect to the first plurality of lengths of strap material with the holes of the first and second pluralities of lengths of strap material located at the overlying intersecting portions of the lengths of strap material, inserting connectors through the holes of the first and second pluralities of lengths of strap material at the intersections of the lengths of strap material, and placing rolls of ceiling material on the support lattice and unrolling the rolls of ceiling material across the support lattice between the rows of connectors.
Claim 7
Dependent Claim
28 words

Claim 8
Dependent Claim
219 words
A suspended ceiling assembly, a support lattice disposed in an approximately horizontal attitude comprising a first plurality of elongated resilient flat straps each extending parallel to one another and equally spaced from one another and a second plurality of elongated resilient flat straps each extending parallel to one another and equally spaced from one another and extending at right angles with respect to and overlying said first plurality of straps and defining with said first plurality of straps a plurality of rectangular openings, a plurality of sheets of elongated ceiling material supported by said support lattice, said sheets of ceiling material being oriented with their long dimensions extending parallel to each other and parallel to one of said first or second pluralities of straps, and sheets of material being of a width sufficient to span the space between adjacent ones of one of the first or second pluralities of straps and of a length sufficient to extend across several ones of the other of the first or second pluralities of straps so that the rectangular openings defined by said first and second pluralities of straps are closed by said sheets of ceiling material, and suspension means connected to said first and second pluralities of straps at their overlying portions for suspending the ceiling assembly from above the support lattice.
