Clip structure for a concealed grid structure of a suspended ceiling

Claim 2

A clip member for use in suspended ceiling structures utilizing panel-supporting grid runners of inverted T-shape in transverse cross-section, having a flat central vertical web portion terminating at its lower edge in oppositely directed outwardly extending flanges disposed in a common plane, adapted to receive and support the edge portions of cooperable ceiling panels, with such web portions terminating at its upper edge in a longitudinally extending bead having a transverse width greater than the thickness of said web to form a generally T-shaped upper edge portion, said clip member comprising a single piece of strip stock formed to provide an upper mounting structure and a lower runner-supporting structure integrally connected therewith, the runner-supporting structure comprising a pair of walls which are connected at their bottom edges, and extend upwardly therefrom in diverging directions with each wall having a notch therein of generally T-shaped configuration, aligned with one another, and each defining a relatively narrow leg portion having parallel edges spaced apart a distance slightly greater than the thickness of such a runner web, and opening in common at their connecting bottom edges, each notch, at the top thereof, having a relatively larger portion, communicating with said narrow leg portion, of a size to receive the bead of such a runner with such larger portion having a configuration generally complemental to the cross-sectional configuration of such a bead, said larger portion having bottom edge portions extending laterally outward from the respective vertical edges of said narrow portion, disposed to engage adjacent cooperable portions of such a bead for supporting the latter and thereby such a runner therefrom, with the latter adapted to be interlocked with the clip by insertion of the bead of such runner in said larger portion and said web in said narrow portion, and relative sliding movement between the clip and runner, said mounting structure comprising two mounting portions, each extending downwardly and outwardly from the upper free edge of a corresponding wall of said pair to form a clip of generally M-shape in transverse cross section, with each of said mounting portions adapted to engage respective cooperable upwardly facing means of a support member of inverted C-shaped configuration.

Claim 3

A clip member for use in suspended ceiling structures utilizing panel-supporting grid runners of inverted T-shape in transverse cross-section, having a flat central vertical web portion terminating at its lower edge in oppositely directed outwardly extending flanges disposed in a common plane, adapted to receive and support the edge portions of cooperable ceiling panels, with such web portions terminating at its upper edge in a longitudinally extending bead having a transverse width greater than the thickness of said web to form a generally T-shaped upper edge portion, said clip member comprising a single piece of strip stock formed to provide an upper mounting structure and a lower runner-supporting structure integrally connected therewith, the runner-supporting structure having notch means therein of generally T-shaped configuration, defining a relatively narrow leg portion having parallel edges spaced apart a distance slightly greater than the thickness of such a runner web, opening on the bottom edge portion of the clip, said notch means, at the top thereof, having a relatively larger portion, communicating with said narrow leg portion, of a size to receive the bead of such a runner with such larger portion having a configuration generally complemental to the cross-sectional configuration of such a bead, said larger portion having bottom edge portions extending laterally outward from the respective vertical edges of said narrow portion, disposed to engage adjacent cooperable portions of such a bead for supporting the latter and thereby such a runner therefrom, with the latter adapted to be interlocked with the clip by insertion of the bead of such runner in said larger portion and said web in said narrow portion, and relative sliding movement between the clip and runner, said mounting structure comprising a pair of mounting parts each generally inverted U-shape in transverse cross-section which are connected by an intermediate laterally extending connecting portion with the inner legs of the respective mounting portions adapted to engage the longitudinally extending free edge portions of a so-called hat-shaped channel member, for support therefrom, said runner-supporting structure extending downwardly from said mounting structure, said runner-supporting structure comprising a downwardly depending wall being formed from the stock of said laterally extending intermediate connection portion.

Claim 4

A clip member for use in suspended ceiling structures utilizing panel-supporting grid runners of inverted T-shape in transverse cross-section, having a flat central vertical web portion terminating at its lower edge in oppositely directed outwardly extending flanges disposed in a common plane, adapted to receive and support the edge portions of cooperable ceiling panels, with such web portions terminating at its upper edge in a longitudinally extending bead having a transverse width greater than the thickness of said web to form a generally T-shaped upper edge portion, said clip member comprising a single piece of strip stock formed to provide an upper mounting structure and a lower runner-supporting structure integrally connected therewith, the runner-supporting structure having notch means therein of generally T-shaped configuration, defining a relatively narrow leg portion having parallel edges spaced apart a distance slightly greater than the thickness of such a runner web, opening on the bottom edge portion of the clip, said notch means, at the top thereof, having a relatively larger portion, communicating with said narrow leg portion, of a size to receive the bead of such a runner with such larger portion having a configuration generally complemental to the cross-sectional configuration of such a bead, said larger portion having bottom edge portions extending laterally outward from the respective vertical edges of said narrow portion, disposed to engage adjacent cooperable portions of such a bead for supporting the latter and thereby such a runner therefrom, with the latter adapted to be interlocked with the clip by insertion of the bead of such runner in said larger portion and said web in said narrow portion, and relative sliding movement between the clip and runner, said mounting structure comprising a pair of mounting parts each generally inverted U-shape in transverse cross-section which are connected by an intermediate laterally extending connecting portion with the inner legs of the respective mounting portions adapted to engage the longitudinally extending free edge portions of a so-called hat-shaped channel member, for support therefrom, said runner-supporting structure extending downwardly from said mounting structure, said runner-supporting structure comprising a downwardly depending wall being formed from the stock of said laterally extending intermediate connection portion.

Claim 5

A clip according to claim 2, wherein said wall of the runner-supporting structure is disposed in the plane of the outer leg of one of said mounting portions.

Claim 6

A clip according to claim 2, wherein said runner-supporting structure comprises a pair of downwardly depending walls, each disposed in the plane of a respective outer leg of said mounting portions, said T-shaped notch means comprising a T-shaped notch in each of said downwardly depending walls, said notches being laterally aligned with the vertical portions thereof opening on the respective lower edges of the associated wall, for cooperable reception and support of the T-shaped edge portion of a runner to be suspended thereby.
