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 an upper flange, a vertical back, and a lower flange having at least one tab configured to engage and retain the flange of each 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 , further comprising: a plurality of retaining features formed in the upper flange of each wall bracket, wherein each retaining feature engages and retains the bulb of a grid member.

4 . The ceiling suspension system of claim 3 , wherein the retaining features are configured to retain the bulb of each grid member on opposing sides of the bulb.

5 . The ceiling suspension system of claim 3 , wherein the retaining features prevent lateral movement of the grid members.

6 . The ceiling suspension system of claim 3 , wherein the retaining features prevent rotation of the grid members.

7 . The ceiling suspension system of claim 1 , wherein a portion of the upper flange of each wall support bracket extends downwardly.

8 . The ceiling suspension system of claim 7 , wherein a height between the portion of the upper flange of each wall support bracket that extends downwardly and the lower flange is less than a height of the grid members.

9 . The ceiling suspension system of claim 1 , wherein the grid members rest on the lower flange of the plurality of wall support brackets.

10 . The ceiling suspension system of claim 9 , wherein the grid members are retained between the upper flange and the lower flange of the wall support brackets.

11 . The ceiling suspension system of claim 1 , wherein the tabs are formed using cut portions of the plurality of wall support brackets.

12 . The ceiling suspension system of claim 1 , wherein the tabs are substantially parallel to the lower flange or inclined downward toward the lower flange.

13 . A method of installing a ceiling suspension system, comprising:
providing a wall support bracket having an upper flange, a vertical back, and a lower flange and a grid member having a bulb, a web and a flange; inserting the grid member into the wall support bracket between the upper flange and the lower flange; rotating the grid member until the bulb of the grid member engages a retaining feature formed in the upper flange; and further rotating the grid member until the flange of the grid member engages a tab formed in the lower flange.

14 . The method of claim 13 , wherein inserting the grid member into the wall support bracket comprises initially orienting the grid member at an angle relative to the wall support bracket.

15 . The method of claim 13 , wherein the bulb of the grid member is retained on opposing sides of the bulb.

16 . The method of claim 13 , wherein after rotating the grid member until the flange of the grid member engages a tab formed in the lower flange, the grid member is retained between the retaining feature and the lower flange.

17 . The method of claim 16 , wherein the tab in the lower flange is formed using cut portions of the plurality of wall support brackets.

18 . The method of claim 17 , wherein the grid member rests on the lower flange of the wall support bracket.

19 . The method of claim 13 , further comprising: providing a pair of opposing wall support brackets having an upper flange, a vertical back, and a lower flange; inserting the grid member into the wall support bracket between the upper flange and the lower flange; and rotating the grid member until the bulb of the grid member engages a retaining feature formed in the upper flange and until the flange of the grid member engages a tab formed in the lower flange.

20 . The method of claim 19 , wherein the pair of opposing wall supports mount the ceiling grid system to walls of a structure.
