Abstract

A ceiling panel having an upper face, a lower face opposite the upper face, and first through fourth edges having a first edge portion adjacent the upper face and a second edge portion below the first edge portion. Each of the first and second edges may have a tongue and each of the third and fourth edges may have a groove. The first edge portion of each of the third and fourth edges may include a first flange having a distal surface. The first edge portion of each of the first and second edges may include a first recess having a first recess wall surface. The first flange may nest within the first recess of an identical adjacent ceiling panel with the distal surface of the first flange of the ceiling panel being spaced from the first recess wall surface of the first recess of the identical adjacent ceiling panel.

First claim

What is claimed is:

1. A ceiling system comprising:
one or more ceiling panels comprising:
an upper face;
a lower face opposite the upper face;
a first edge, a second edge, a third edge opposite the first edge, and a fourth edge opposite the second edge, wherein each of the first and second edges comprise a tongue having a distal surface, and each of the third and fourth edges comprise a groove having a groove wall surface;
wherein each of the first, second, third, and fourth edges comprise a first edge portion adjacent the upper face and a second edge portion below the first edge portion;
wherein the second edge portion of each of the first and second edges comprises the tongue and the second edge portion of each of the third and fourth edges comprises the groove;
wherein the first edge portion of each of the third and fourth edges comprises a first flange that terminates in a distal surface and the first edge portion of each of the first and second edges comprises a first recess comprising a first recess wall surface; and

wherein the first flange of a first one of the ceiling panels is configured to nest within the first recess of an adjacent one of the ceiling panels with the distal surface of the first flange of the first one of the ceiling panels being spaced from the first recess wall surface of the first recess of the adjacent one of the ceiling panels.

2. The ceiling system according to claim 1 further comprising:
the one or more ceiling panels further comprising:
each of the first, second, third, and fourth edges comprising a third edge portion adjacent the lower face, the second edge portion located between the first and third edge portions;
wherein the third edge portion of each of the first and second edges comprises a second recess comprising a second recess wall surface;
wherein the third edge portion of each of the third and fourth edges comprises a second flange that terminates in a distal surface; and

wherein when the first one of the ceiling panels is in an interlocked arrangement with the adjacent one of the ceiling panels, one of the second flanges of the first one of the ceiling panels nests within one of the second recesses of the adjacent one of the ceiling panels so that the distal surface of the one of the second flanges of the first one of the ceiling panels abuts the second recess wall surface of the one of the second recesses of the adjacent one of the ceiling panels.

3. The ceiling system according to claim 2 wherein for each of the one or more ceiling panels, the first recess has a first length measured from the first recess wall surface to the distal surface of the tongue and the first flange has a second length measured from the groove wall surface of the groove to the distal surface of the first flange, the first and second lengths being substantially the same.

4. The ceiling system according to claim 3 wherein for each of the one or more ceiling panels, the tongue has a third length measured from the second recess wall surface to the distal surface of the tongue and the groove has a fourth length measured from the distal surface of the second flange to the groove wall surface of the groove, the fourth length being greater than the third length.

5. The ceiling system according to claim 2 wherein when the first one of the ceiling panels is interlocked with the adjacent one of the ceiling panels, the second recess wall surface of the one of the second recesses of the adjacent one of the ceiling panels abuts against the distal surface of the one of the second flanges of the first one of the ceiling panels, the groove wall surface of the groove of the first one of the ceiling panels is spaced apart from the distal surface of the tongue of the adjacent one of the ceiling panels, and the distal surface of the first flange of the first one of the ceiling panels is spaced apart from the first recess wall surface of the first recess of the adjacent one of the ceiling panels.

6. The ceiling system according to claim 2 wherein for each of the one or more ceiling panels, the groove is defined by a lower flange surface of the first flange, an upper flange surface of the second flange, and the groove wall surface extending between the upper flange surface of the second flange and the lower flange surface of the first flange, and wherein the first flange has a first length measured from the groove wall surface to the distal surface of the first flange, the second flange has a second length measured from the groove wall surface to the distal surface of the second flange, and the first length is greater than the second length.

7. The ceiling system according to claim 1 wherein the ceiling panels are formed from a fibrous material.

8. The ceiling system according to claim 7 wherein the fibrous material is selected from mineral fiber, mineral wool, rock wool, stone wool, and combinations thereof.

9. A ceiling system comprising:
one or more ceiling panels comprising:
an upper face;
a lower face opposite the upper face;
a first edge, a second edge, a third edge opposite the first edge, and a fourth edge opposite the second edge, wherein each of the first and second edges comprise a tongue having a distal surface, and wherein each of the third and fourth edges comprise a groove having a groove wall surface;
wherein each of the first, second, third, and fourth edges comprise a first edge portion adjacent the upper face and a second edge portion below the first edge portion;
wherein the second edge portion of each of the first and second edges comprises the tongue and the second edge portion of each of the third and fourth edges comprises the groove;
wherein the first edge portion of each of the third and fourth edges comprises a first flange that terminates in a distal surface, the first flange having a first length measured from the groove wall surface to the distal surface of the flange;
wherein the first edge portion of each of the first and second edges comprises a first recess comprising a first recess wall surface, the first recess comprising a second length measured from the first recess wall surface to the distal surface of the tongue; and
wherein the first and second lengths are the same.

10. The ceiling system according to claim 9 further comprising:
the one or more ceiling panels further comprising:
each of the first, second, third, and fourth edges comprising a third edge portion adjacent the lower face, the second edge portion located between the first and third edge portions;
wherein the third edge portion of each of the first and second edges comprises a second recess comprising a second recess wall surface;
wherein the third edge portion of each of the third and fourth edges comprises a second flange that terminates in a distal surface; and

wherein the second flange of a first one of the ceiling panels is configured to nest within the second recess of an adjacent one of the ceiling panels such that the distal surface of the second flange of the one of the ceiling panels abuts the second recess wall surface of the second recess of the adjacent one of the ceiling panels.

11. The ceiling system according to claim 10 wherein the distal surface of the tongue of the adjacent one of the ceiling panels is configured to nest within the groove of the first one of the ceiling panels such that the distal surface of the tongue of the adjacent one of the ceiling panels is spaced apart from the groove wall surface of the groove of the first one of the ceiling panels by a first distance.

12. The ceiling system according to claim 11 wherein the distal surface of the first flange of the first one of the ceiling panels is configure
