Suspended ceiling systems having a plurality of l-shaped panels

Abstract

A ceiling system is provided for use in a building space. The ceiling system includes a grid system may extend to a plurality of walls and separates the building space into an occupiable space below the grid system and a plenum space above the grid system; and a plurality of ceiling tiles that are supported by the grid system. The grid system includes main beams connected to cross tees connected to right angle brackets with clips for easy installation.

What is claimed is: 
     
         1 . A ceiling system forming a grid for use in a building space having a plurality of walls, the ceiling system comprising:
 at least two main beams;   a first cross tee attached to: (1) the first main beam or a first cross-tee-spanning-a-first-and-second-main-beam at one end of the first cross tee and (2) a first bracket at the opposite end of the first cross tee;   a second cross tee attached to: (1) the first bracket at one end of the second cross tee and (2) a second bracket at the opposite end of the second cross tee;   a third cross tee attached to: (1) the second bracket at one end of the third cross tee and (2) the second main beam or a second cross-tee-spanning-a-first-and-second-main-beam at the opposite end of the third cross tee;   wherein both the first bracket and second bracket comprise:
 a first section comprising: a first vertical wall extending upward from a bottom flange, and 
 a second section comprising a second vertical wall extending upward from the bottom flange, 
 wherein the first section and second section are connected to each other at approximately a ninety-degree angle. 
   
     
     
         2 . The ceiling system of  claim 1 , wherein the first main beam and second main beam are parallel. 
     
     
         3 . The ceiling system of  claim 1 , wherein the grid forms an L-shaped opening adapted to receive at least one laid in ceiling tile. 
     
     
         4 . The ceiling system of  claim 3 , further includes a laid in ceiling tile. 
     
     
         5 . The ceiling system of  claim 4 , wherein the ceiling system includes two or more laid in ceiling tiles. 
     
     
         6 . The ceiling system of  claim 5  wherein the laid in ceiling tiles are L-shaped. 
     
     
         7 . A ceiling system forming a grid for use in a building space having a plurality of walls, the ceiling system comprising:
 at least two main beams;   a first cross tee attached to: (1) the first main beam or a first cross-tee-spanning-a-first-and-second-main-beam at one end of the first cross tee and (2) a first bracket at the opposite end of the first cross tee;   a second cross tee attached to: (1) the first bracket at one end of the second cross tee and (2) a third cross tee having two opposite ends connecting the first main beam to the second main beam wherein the second cross tee attaches to the third cross tee at a location between the two ends of the third cross tee or a first main beam;   wherein both the first bracket comprises:
 a first section comprising: a first vertical wall extending upward from a bottom flange, and 
 a second section comprising a second vertical wall extending upward from the bottom flange, 
 wherein the first section and second section are connected to each other at approximately a ninety-degree angle. 
   
     
     
         8 . The ceiling system of  claim 7 , wherein the first main beam and second main beam are parallel. 
     
     
         9 . The ceiling system of  claim 7 , wherein the grid forms an L-shaped opening adapted to receive at least one laid in ceiling tile. 
     
     
         10 . The ceiling system of  claim 9 , further includes a laid in ceiling tile. 
     
     
         11 . The ceiling system of  claim 10 , wherein the ceiling system includes two or more laid in ceiling tiles. 
     
     
         12 . The ceiling system of  claim 11  wherein the laid in ceiling tiles are L-shaped and a shape other than L-shaped. 
     
     
         13 . A ceiling system forming a grid for use in a building space having a plurality of walls, the ceiling system comprising:
 at least two main beams;   a first cross tee attached to: (1) the first main beam or a first cross-tee-spanning-a-first-and-second-main-beam at one end of the first cross tee and (2) a first bracket at the opposite end of the first cross tee;   a second cross tee attached to: (1) the first bracket at one end of the second cross tee and (2) a second bracket at the opposite end of the second cross tee;   a third cross tee attached to: (1) the second bracket at one end of the third cross tee and (2) the first main beam or the first cross-tee-spanning-a-first-and-second-main-beam at the opposite end of the third cross tee;   wherein both the first bracket and second bracket comprise:
 a first section comprising: a first vertical wall extending upward from a bottom flange, and 
 a second section comprising a second vertical wall extending upward from the bottom flange, 
 wherein the first section and second section are connected to each other at approximately a ninety-degree angle. 
   
     
     
         14 . The ceiling system of  claim 13 , wherein the first main beam and second main beam are parallel. 
     
     
         15 . The ceiling system of  claim 13 , wherein the grid forms a C-shaped opening adapted to receive at least one laid in ceiling tile. 
     
     
         16 . The ceiling system of  claim 15 , further includes a laid in ceiling tile. 
     
     
         17 . The ceiling system of  claim 16 , wherein the ceiling system includes two or more laid in ceiling tiles. 
     
     
         18 . The ceiling system of  claim 17  wherein the laid in ceiling tiles are C-shaped and a shape other than C-shaped.
