Claim 6

The combination of claim 1 wherein: a first two of said members have vertical wall surface portions with flanges at end margins thereof turned back toward each other to form facing grooves on each of said members, and; the other two of said members have vertical wall surface portions with inwardly turned flanges at end margins thereof received in said grooves.

Claim 7

The combination of claim 1 wherein: each of said members has a vertical wall surface portion with a first inturned flange at the top margin thereof providing said panel support means and an upturned flange at the inner margin of said inturned flange providing said panel locating means, and a second inturned flange at the lower margin of said wall surface portion, and a third inturned flange at an end margin of said wall surface portion, and an outwardly turned flange beginning at the inner margin of said third flange and extending generally parallel to said third flange and providing an outwardly facing vertical groove to receive the vertical wall portion of another of said members at an unflanged end thereof.

Claim 8

The combination of claim 6 wherein the unflanged end of each of said members is received in the vertical groove in an adjacent one of said members and affixed thereto.

Claim 9

The combination of claim 6 wherein a panel rests on at least two of said wall members and between said upturned flanges to form a coffer.

Claim 10

The combination of claim 1 and further comprising: upstanding webs on said runners; a plurality of frames like said first frame, said frames being disposed in adjacent areas of said grid on opposite sides of said webs, a plurality of panels, each different one of said panels being mounted to a different one of said frames to form a coffer.

Claim 11

The combination of claim 9 wherein said frames are received entirely atop said suspended grid, the combination further comprising: a second suspended grid above the first mentioned grid, said wall members having upper flanges extending horizontally over portions of said second grid, and said panels being received on said wall members at said flanges.

Claim 12

A member for a coffered ceiling, said member comprising: a wall portion which is longer from end to end than it is high from the lower margin to the upper margin thereof; an upper flange inwardly turned at the upper margin of said wall portion; a lower flange inwardly turned at the lower margin of said wall portion; a third flange inwardly turned from one end margin of said wall portion, and; an outwardly turned flange beginning at the inner margin of said third flange and extending generally parallel to said third flange and providing an outwardly facing groove between said third flange and said outwardly turned flange.

Claim 13

A member for a coffered ceiling, said member comprising: a wall portion which is longer from end to end than it is high from the lower margin to the upper margin thereof; an upper flange inwardly turned at the upper margin of said wall portion; a lower flange inwardly turned at the lower margin of said wall portion; a third flange inwardly turned from one end margin of said wall portion, and; an outwardly turned flange beginning at the inner margin of said third flange and extending generally parallel to said third flange and providing an outwardly facing groove between said third flange and said outwardly turned flange.

Claim 14

The member of claim 11 wherein the other end margin of said wall portion is unflanged and receivable in a groove of another member like the member defined in claim 11.

Claim 15

The member of claim 11 and further comprising: a locator flange upwardly turned at the inner margin of said upper flange, said member terminating at the upper margin of said locator flange.

Claim 16

In a coffered ceiling, the combination comprising: a plurality of coffer frame forming members, each of said members having its ends joined with two others of said members to form a first coffer frame, at least two of said members having panel support means thereon adjacent an upper margin thereof; a suspended grid receiving said first frame thereon, said grid having a plurality of elongated horizontally extending main runners in parallel horizontally spaced relationship to each other and having a plurality of elongated horizontally extending cross runners in parallel horizontally spaced relationship to each other and intersecting said main runners, the runners of one of said pluralities of runners having outwardly extending shelves thereon, one of said members of said first frame being rested upon and supported by one of said shelves on one of said runners, and another of said members of said first frame being rested upon and supported by one of said shelves of another of said runners whereby said first coffer frame is supported on said grid; a plurality of coffer frames like said first frame, said frames being disposed in adjacent areas of said grid, each of said frames being supported on said shelves of said grid runners independently of each other of said frames.

Claim 17

In a coffered ceiling, the combination comprising: a plurality of coffer frame forming members, each of said members having its ends joined with two others of said members to form a first coffer frame, at least two of said members having panel support means thereon adjacent an upper margin thereof; a suspended grid receiving said first frame thereon, said grid having a plurality of elongated horizontally extending main runners in parallel horizontally spaced relationship to each other and having a plurality of elongated horizontally extending cross runners in parallel horizontally spaced relationship to each other and intersecting said main runners, the runners of one of said pluralities of runners having outwardly extending shelves thereon, one of said members of said first frame being rested upon and supported by one of said shelves on one of said runners, and another of said members of said first frame being rested upon and supported by one of said shelves of another of said runners whereby said first coffer frame is supported on said grid; a plurality of coffer frames like said first frame, said frames being disposed in adjacent areas of said grid, each of said frames being supported on said shelves of said grid runners independently of each other of said frames.
