Abstract

Abstract A one-piece panel clip is provided which is adapted to support a plurality of elongate ceiling panels so as to form a ceiling construction. The panel clip comprises a planar support strip which mates with the under surface of a ceiling support rail and includes a series of bendable tabs spaced along each side thereof for securing the panel clip to the support rail. Depending downwardly from the elongate support strip are panel hanging portions which are formed integrally with the support strip and which are used to support the ceiling panels, the panel hanging portions being shaped to engage longitudinal flanges formed on opposite sides of the ceiling panels.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 153 words
In combination with a support rail for supporting ceiling panels, a one-piece panel clip for supporting a plurality of elongate panels, said panel clip comprising: a central, elongate strip which engages the bottom surface of the support rail along the length of the support rail; means, comprising at least three bendable tabs formed integrally with said strip and located in spaced relationship along both sides of said strip, for resiliently holding said elongate strip in a mating position along the bottom surface of the support rail; and means, compising at least three evenly spaced panel hanging portions formed integrally with said strip and extending outwardly from both of the sides of said strip, for supporting a plurality of elongate ceiling panels, said clip being made of a material with a melting point substantially below that of the support rail such that said clip, upon exposure to fire, will disengage from the support rail.
Claim 2
Dependent Claim 153 words
In combination with a support rail for supporting ceiling panels, a one-piece panel clip for supporting a plurality of elongate panels, said panel clip comprising: a central, elongate strip which engages the bottom surface of the support rail along the length of the support rail; means, comprising at least three bendable tabs formed integrally with said strip and located in spaced relationship along both sides of said strip, for resiliently holding said elongate strip in a mating position along the bottom surface of the support rail; and means, compising at least three evenly spaced panel hanging portions formed integrally with said strip and extending outwardly from both of the sides of said strip, for supporting a plurality of elongate ceiling panels, said clip being made of a material with a melting point substantially below that of the support rail such that said clip, upon exposure to fire, will disengage from the support rail.
Claim 3
Dependent Claim 42 words
A panel clip as claimed in claim 1 wherein said hanging portions are provided as opposed pairs on each side of said elongate strip, are cut out from said strip and are disposed centrally of alternate ones of said panel hanging portions.
Claim 4
Dependent Claim 27 words
A panel clip as claimed in claim 1 wherein said bendable tabs are provided in an alternating, longitudinal spaced pattern on each side of said elongate strip.
Claim 5
Dependent Claim 24 words
A panel clip as claimed in claim 2 wherein said bendable tabs are provided as opposed pairs on each side of said elongate strip.
Claim 6
Dependent Claim 35 words
A panel clip as claimed in claim 1 wherein said hanging portions, in use, depend downwardly from said strip and comprise laterally extending flanges for engaging reciprocally shaped, longitudinally extending flanges of the elongate panels.
Claim 7
Dependent Claim 171 words
A ceiling assembly comprising: a plurality of spaced, parallel, elongate rails; means for suspending said rail, substantially in a common plane, from a superjacent structure; an array of elongate panels disposed in horizontal plane and extending in spaced parallel relation to each other beneath, and transversely of, said rails: a plurality of fusible, one-piece panel clips with a melting point substantially below the melting point of said rails supporting said panels from said rails such that said clips, upon exposure to fire, will disengage from the support rail, each said panel clip comprising a central, elongate, generally planar strip which engages the underside of a said rail, at least three bendable tabs, formed integrally with said strip and located on opposite sides of said strip, for resiliently holding said elongate strip in mating relationship with said rail, and at least three evenly spaced panel hanging portions formed integrally with said strip on opposite sides thereof and depending downwardly from opposite sides of said strip, for supporting said array of elongate panels.
Claim 8
Dependent Claim 171 words
A ceiling assembly comprising: a plurality of spaced, parallel, elongate rails; means for suspending said rail, substantially in a common plane, from a superjacent structure; an array of elongate panels disposed in horizontal plane and extending in spaced parallel relation to each other beneath, and transversely of, said rails: a plurality of fusible, one-piece panel clips with a melting point substantially below the melting point of said rails supporting said panels from said rails such that said clips, upon exposure to fire, will disengage from the support rail, each said panel clip comprising a central, elongate, generally planar strip which engages the underside of a said rail, at least three bendable tabs, formed integrally with said strip and located on opposite sides of said strip, for resiliently holding said elongate strip in mating relationship with said rail, and at least three evenly spaced panel hanging portions formed integrally with said strip on opposite sides thereof and depending downwardly from opposite sides of said strip, for supporting said array of elongate panels.
Claim 9
Dependent Claim 34 words
A ceiling assembly as claimed in claim 6 wherein said bendable tabs are provided in an alternating longitudinally spaced pattern on each side of said elongate strip and are cut out from said strip.
Claim 10
Dependent Claim 24 words
A ceiling assembly as claimed in claim 5 wherein said bendable tabs are provided as opposed pairs on each side of said elongate strip.
Claim 11
Dependent Claim 24 words
A ceiling assembly as claimed in claim 5 wherein said hanging portions are provided as opposed pairs on each side of said elongate strip.
