Abstract

A ceiling suspension system is disclosed and includes a plurality of grid members configured to form a grid for the ceiling suspension system, each grid member comprising a bulb, a web and a flange. The system also includes a plurality of wall support brackets configured to mount the grid to walls in a structure. Each wall support bracket comprises a vertical back, a lower flange at a lower end of the vertical back, and an upper flange at an upper end of the vertical back. Further, the upper flange is generally V-shaped when viewed longitudinally and each wall support bracket only one tab in the lower flange for each grid member. Moreover, the only one tab is configured to engage and retain the flange of a respective grid member, such that the respective grid member rests on the lower flange.

First claim

What is claimed is:

1. A ceiling suspension system, comprising:
a plurality of grid members, each grid member comprising a bulb, a web, and a flange; and
a plurality of wall support brackets, each wall support bracket comprising a vertical back, a lower flange at a lower end of the vertical back, and an upper flange at an upper end of the vertical back, wherein the upper flange comprises a generally V-shaped profile that extends to an apex towards the lower flange when viewed longitudinally, and wherein each wall support bracket comprises:
a plurality of tabs, each tab configured to engage and retain the flange of a grid member; and
a plurality of holes formed in the upper flange, each hole configured to engage and retain the bulb of a grid member.

2. The ceiling suspension system of claim 1 , wherein the vertical back and the lower flange of each of the plurality of wall support brackets are substantially perpendicular.

3. The ceiling suspension system of claim 1 , wherein a height between the apex of the upper flange and the lower flange is less than a height of the plurality of grid members.

4. The ceiling suspension system of claim 3 , wherein the upper flange is configured to deflect upwards to receive the plurality of grid members.

5. The ceiling suspension system of claim 1 , wherein the plurality of holes prevent rotation of the plurality of grid members.

6. The ceiling suspension system of claim 5 , wherein the plurality of grid members rests on the lower flange of the plurality of wall support brackets.

7. The ceiling suspension system of claim 6 , wherein each wall support bracket is retained between the lower flange and one of the plurality of holes in the upper flange.

8. The ceiling suspension system of claim 1 , wherein the plurality of tabs is formed using a cut portion of the vertical back of the plurality of wall support brackets.

9. The ceiling suspension system of claim 1 , wherein the plurality of tabs are inclined downward toward the lower flange.

10. The ceiling suspension system of claim 1 , wherein the plurality of tabs are substantially parallel to the lower flange.

11. The ceiling suspension system of claim 1 , wherein each of the plurality of tabs comprises a locking feature configured to engage and retain the flange of a respective grid member.

12. The ceiling suspension system of claim 11 , wherein the locking feature comprises a finger that extends downward toward the lower flange.

13. A ceiling suspension system, comprising:
a grid member comprising a bulb, a web, and a flange; and
a pair of opposing wall support brackets, each wall support bracket comprising a vertical back, a lower flange at a lower end of the vertical back, and an upper flange at an upper end of the vertical back, wherein the upper flange comprises a generally V-shaped profile that extends to an apex towards the lower flange when viewed longitudinally, and wherein each wall support bracket comprises:
at least one tab configured to engage and retain the flange of the grid member; and
at least one hole formed in the upper flange and configured to engage and retain the bulb of the grid member.

14. The ceiling suspension system of claim 13 , wherein the vertical back and the lower flange of each of the pair of opposing wall support brackets are substantially perpendicular.

15. The ceiling suspension system of claim 13 , wherein a height between the apex of the upper flange and the lower flange is less than a height of the grid member.

16. The ceiling suspension system of claim 15 , wherein a height of the vertical back of each of the pair of opposing wall support brackets is greater than a height of the grid member.

17. The ceiling suspension system of claim 15 , wherein the upper flange of each of the pair of opposing wall support brackets is configured to deflect upwards to receive the bulb of the grid member into the at least one hole of each of the pair of opposing wall support brackets.

18. The ceiling suspension system of claim 17 , wherein the at least one hole prevents rotation of the grid member.

19. The ceiling suspension system of claim 18 , wherein the grid member rests on the lower flange of the pair of wall support brackets.

20. The ceiling suspension system of claim 19 , wherein the grid member is retained between the lower flange and the at least one hole in the upper flange of each of the pair of opposing wall support brackets.
