Abstract
Abstract A ceiling hanger adapted to be removably installed on a horizontal supporting strip of a tile ceiling structure wherein tile panels are provided with edge portions resting on opposed edge portions of the supporting strip. The hanger includes a plate having a U-shaped end portion embracing one edge of the supporting strip, a midportion underlying the supporting strip, and a retaining clip embracing the opposite edge of the supporting strip and retaining the plate midportion juxtaposed to the underside of the supporting strip. The plate further includes a distal hanger portion which is bent downwardly about a connecting portion of the plate to provide a support such as for hanging an advertisement or the like from the ceiling supporting strip.

Total Claims: 17
Claim 1
Independent Claim
175 words
For use with a ceiling structure having a pair of flat ceiling panels having opposed edge portions carried on a horizontal supporting strip, an improved hanger comprising: a plate having a U-shaped end portion adapted to embrace one edge of the supporting strip, a midportion adapted to underlie the supporting strip when the turned end is disposed to embrace the one edge thereof, a distal hanger porton, and a bendable connecting portion connecting the hanger portion to said midportion; and a U-shaped retaining clip having a pair of spaced sidewalls and a bight portion connecting the sidewalls at one edge thereof, said bight portion being provided with a slot for extension of said plate hanger portion therethrough, said clip being adapted to embrace the edge of the supporting strip opposite said one edge to secure said midportion across the underside of the strip, said connecting portion being turned to cause said hanger portion to extend downwardly from said secured midportion and prevent movement of said clip away from its edge-embracing relationship with the supporting strip.
