Abstract
Abstract The present invention is directed to an integrated ceiling system of the electrified hung ceiling type, characterized by ease of installation, flexibility, structural rigidity and aesthetic appearance. The ceiling includes longitudinally extending runners, transversely extending tile supports and locking struts which interfit between adjacent runners, rigidly coupling the same. A characterizing feature of the structure lies in the novel attachment elements which enable the parts to be accurately and easily integrated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
331 words
An electrified hung ceiling grid construction comprising, in combination, a plurality of horizontally disposed parallel runner members supported in coplanar alignment from a building structure, said runner members including a vertically directed mounting web and horizontally disposed tile support flanges, upper and lower spaced locking flanges in proximate spaced relation to and disposed on either side of said mounting web, said locking flanges and web defining vertically directed locking channels, a plurality of longitudinally spaced, transversely extending locator apertures formed in said mounting webs, cross strut means extending between adjacent runners and locking the same against relative transverse movement, said strut means including at their ends projecting tab members adapted to be inserted through said locator apertures, and adjacent the ends of said struts locking clip members including resilient locking means projecting beyond the upper and lower surfaces of said struts, said locking means being insertible into the space between said locking flanges and being extended into tightly wedged position within said locking channels responsive to rotation of said struts about their longitudinal axes, a plurality of tile support hangers extending between adjacent parallel runners, said support hangers including horizontally extending tile support ledges disposed in coplanar alignment with the tile support flanges of said runners, a plurality of alignment slots formed in said mounting webs of said runners, said slots being regularly spaced apart in accordance with the desired spacing of said hangers, complemental connector means on said hangers extending through said alignment slots and linking the distal ends of adjacent support hangers, said connector means including a finger on one said hanger slidably engaging a finger socket on the other said hanger, thus to permit relative horizontal movement between said adjacent hangers, the spacing between the clip members at opposite ends of said struts being coordinated with the length of said support hangers whereby, upon rotation of said struts into locking position, the ends of said ledges of said struts are tightly abutted against said flanges of said runners.
Claim 2
Dependent Claim
331 words
An electrified hung ceiling grid construction comprising, in combination, a plurality of horizontally disposed parallel runner members supported in coplanar alignment from a building structure, said runner members including a vertically directed mounting web and horizontally disposed tile support flanges, upper and lower spaced locking flanges in proximate spaced relation to and disposed on either side of said mounting web, said locking flanges and web defining vertically directed locking channels, a plurality of longitudinally spaced, transversely extending locator apertures formed in said mounting webs, cross strut means extending between adjacent runners and locking the same against relative transverse movement, said strut means including at their ends projecting tab members adapted to be inserted through said locator apertures, and adjacent the ends of said struts locking clip members including resilient locking means projecting beyond the upper and lower surfaces of said struts, said locking means being insertible into the space between said locking flanges and being extended into tightly wedged position within said locking channels responsive to rotation of said struts about their longitudinal axes, a plurality of tile support hangers extending between adjacent parallel runners, said support hangers including horizontally extending tile support ledges disposed in coplanar alignment with the tile support flanges of said runners, a plurality of alignment slots formed in said mounting webs of said runners, said slots being regularly spaced apart in accordance with the desired spacing of said hangers, complemental connector means on said hangers extending through said alignment slots and linking the distal ends of adjacent support hangers, said connector means including a finger on one said hanger slidably engaging a finger socket on the other said hanger, thus to permit relative horizontal movement between said adjacent hangers, the spacing between the clip members at opposite ends of said struts being coordinated with the length of said support hangers whereby, upon rotation of said struts into locking position, the ends of said ledges of said struts are tightly abutted against said flanges of said runners.
Claim 3
Dependent Claim
184 words
An electrified hung ceiling grid construction comprising, in combination, a plurality of horizontally disposed parallel runner members supported in coplanar alignment from a building structure, said runner members including a vertically directed mounting web and horizontally disposed tile support flanges, a plurality of regularly spaced apart alignment slots formed in said web, a plurality of tile support hangers extending between adjacent parallel runners, said support hangers including horizontally extending tile support ledges disposed in coplanar alignment with the tile support flanges of said runners, complemental connector means linking the distal ends of adjacent tile support hangers, said connector means extending through said alignment slots and providing a sliding connection between said adjacent hangers, and cross strut means extending between adjacent runners and locking the same against transverse movement, said cross strut means being insertible between adjacent runners and rotated into locking engagement with said runners, the length of said cross strut means and said hangers being coordinated to urge said ledges of said struts into tightly abutted engagement with said flanges of said runners responsive to rotation of said struts to said locking position.
Claim 4
Dependent Claim
184 words
An electrified hung ceiling grid construction comprising, in combination, a plurality of horizontally disposed parallel runner members supported in coplanar alignment from a building structure, said runner members including a vertically directed mounting web and horizontally disposed tile support flanges, a plurality of regularly spaced apart alignment slots formed in said web, a plurality of tile support hangers extending between adjacent parallel runners, said support hangers including horizontally extending tile support ledges disposed in coplanar alignment with the tile support flanges of said runners, complemental connector means linking the distal ends of adjacent tile support hangers, said connector means extending through said alignment slots and providing a sliding connection between said adjacent hangers, and cross strut means extending between adjacent runners and locking the same against transverse movement, said cross strut means being insertible between adjacent runners and rotated into locking engagement with said runners, the length of said cross strut means and said hangers being coordinated to urge said ledges of said struts into tightly abutted engagement with said flanges of said runners responsive to rotation of said struts to said locking position.
Claim 5
Dependent Claim
44 words
A device in accordance with claim 2 wherein said web includes spaced, transversely extending locator apertures and the ends of said cross strut means include projecting tabs adapted to be inserted through said apertures prior to rotation of said struts into said locking position.
