Abstract
Abstract A suspension system for flanged ceiling tiles and a method of supporting ceiling tiles are provided. Heretofore, flanged ceiling tiles have been affixed to furring strips and the like by stapling the flanges thereto. However, there has been no satisfactory means of suspending tiles of this type below an overhead ceiling structure. In accordance with the invention, an elongate supporting member for such tiles is designed to either suspend the tiles below an overhead ceiling structure or support them directly on an overhead ceiling structure. The supporting member includes an elongate channel having spaced, horizontallyextending flanges along one side thereof, the length of these flanges being less than the length of the tile flanges, with the spacing between the channel flanges preferably exceeding the length of the tile flanges. The supporting members are positioned relative to the ceiling structure so that the horizontallyextending flanges are directly opposite one another to support flanges of tiles extending between the members. These first supported tiles in turn, then support other tiles extending between the first ones.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A method of supporting ceiling tiles from an overhead structure, which ceiling tiles have outwardly-extending flanges on opposite edges and recesses extending between the flanges along the two other opposite edges, said method comprising positioning a first one of the tiles with the flanges supported on two horizontally-extending flanges of two elongate supporting members, inserting one of the flanges of a second tile in one of the recesses of the first tile, supporting a third one of the tiles with its flanges on another two horizontally-extending flanges of the two supporting members with the third tile being in the same plane as the first tile and spaced from the second tile, positioning the second tile in the same plane as the first and third tiles, and moving the third tile into contiguous relationship with the second tile, with the other flange of the second tile received in one of the recesses of the third tile.
Claim 2
Independent Claim
155 words
A method of supporting ceiling tiles from an overhead structure, which ceiling tiles have outwardly-extending flanges on opposite edges and recesses extending between the flanges along the two other opposite edges, said method comprising positioning a first one of the tiles with the flanges supported on two horizontally-extending flanges of two elongate supporting members, inserting one of the flanges of a second tile in one of the recesses of the first tile, supporting a third one of the tiles with its flanges on another two horizontally-extending flanges of the two supporting members with the third tile being in the same plane as the first tile and spaced from the second tile, positioning the second tile in the same plane as the first and third tiles, and moving the third tile into contiguous relationship with the second tile, with the other flange of the second tile received in one of the recesses of the third tile.
Claim 3
Dependent Claim
38 words
A method according to claim 1 characterized by placing a flange of a fourth tile in one of the recesses of the second tile with the fourth tile extending transversely to the row of the first three tiles.
Claim 4
Dependent Claim
221 words
A supporting system for ceiling tiles having outwardly-extending flanges along two opposite edges thereof, said system including a supporting member having side wall means, a plurality of spaced flanges extending outwardly in a common direction from a common edge of said wall means, said wall means having recesses along said common edge thereof between said flanges, said recesses having lengths exceeding the length of the tile flanges, a second supporting member having second side wall means, spaced second flanges extending outwardly in a common direction from a common edge of said second wall means, said second wall means having recesses along said common edge between said second flanges, said second recesses having lengths exceeding the length of the tile flanges, means for supporting said second supporting member in a position such that the flanges of said supporting members face another and are substantially directly opposite one another, a first ceiling tile having outwardly-extending flanges along two opposite edges thereof supported on directly opposite flanges of said first and second supporting members, a second tile having outwardly-extending flanges along two opposite edges thereof supported on directly opposite flanges of said first and second supporting members and spaced from said first tile, and a third tile having outwardly-extending flanges along two opposite edges thereof supported on edges of said first and second tiles.
Claim 5
Dependent Claim
221 words
A supporting system for ceiling tiles having outwardly-extending flanges along two opposite edges thereof, said system including a supporting member having side wall means, a plurality of spaced flanges extending outwardly in a common direction from a common edge of said wall means, said wall means having recesses along said common edge thereof between said flanges, said recesses having lengths exceeding the length of the tile flanges, a second supporting member having second side wall means, spaced second flanges extending outwardly in a common direction from a common edge of said second wall means, said second wall means having recesses along said common edge between said second flanges, said second recesses having lengths exceeding the length of the tile flanges, means for supporting said second supporting member in a position such that the flanges of said supporting members face another and are substantially directly opposite one another, a first ceiling tile having outwardly-extending flanges along two opposite edges thereof supported on directly opposite flanges of said first and second supporting members, a second tile having outwardly-extending flanges along two opposite edges thereof supported on directly opposite flanges of said first and second supporting members and spaced from said first tile, and a third tile having outwardly-extending flanges along two opposite edges thereof supported on edges of said first and second tiles.
Claim 6
Dependent Claim
33 words
A supporting system according to claim 3 characterized further by said supporting member having downwardly-extending flanges spaced from said spaced flanges and positioned to contact portions of the tiles near the tile flanges.
Claim 7
Dependent Claim
40 words
A supporting system according to claim 3 characterized by a fourth tile haVing an outwardly-extending flange extending through one of said recesses of one of said first and second supporting members and supported on an edge of said third tile.
