Abstract
A rectangular ceiling tile to be supported in an exposed type suspended grid system of perpendicularly crossed girders of inverted T-profile. The tile includes a core containing fiber material with two opposite first edges, each forming a recess, and two opposite second edges each forming a recess. The tile forms a projecting, peripheral rim on a lower face of the tile. At least two edge support clips are provided. Each clip has one or more limbs that are inserted into or under a transverse edge surface of the core. Each clip has a magnetic member extending parallel to or coplanar with a major face of the core
Claims19
A rectangular ceiling tile to be supported in an exposed type suspended grid system of perpendicularly crossed girders of inverted T-profile, said tile comprising:
- a) a core containing fiber material with two opposite first edges, each forming a recess, and two opposite second edges each forming a recess, the tile forming a projecting, peripheral rim on a lower face thereof;
- and
- b) at least two edge support clips, each having one or more limbs that are inserted into or under a transverse edge surface of the core, and each having a magnetic member extending parallel to or coplanar with a major face of said core.
An edge support clip for ceiling tiles supported in an exposed type suspended grid system of perpendicularly crossed girders of inverted T-profile, said clip comprising:
- one or more limbs that can be inserted into or under a transverse edge of said ceiling tile;
- a web connected to the one or more limbs, the web having a protruding ledge, the protruding ledge including a magnetic member for attaching said tile to a flange of a ceiling suspension girder of inverted T-profile by magnetic attraction.
A method of installing a rectangular ceiling tile in an exposed type suspended grid system of perpendicularly crossed girders of inverted T-profile, said method comprising:
- a) providing a ceiling tile including a core containing fiber material with two opposite first edges each forming a stepped recess, and two opposite second edges each forming a stepped recess, the tile forming a projecting, peripheral rim along said first and second edges;
- b) inserting at least one edge support clip on each of said two opposite first edges, said clips each having one or more limbs that are inserted into or under a transverse edge surface of said core, and each having a protruding ledge, said protruding ledge of each of said clips extending parallel to or coplanar with a major face of the core, said protruding ledge of each of said clips including a magnetic member;
- c) contacting a surface of a first flange of said girders with the magnetic member of the at least one edge support clip of a first one of the first edges, so as to attach the first edge to the first flange by magnetic attraction;
- and
- d) contacting a surface of a second flange of said girders with the magnetic member of the at least one edge support clip of a second one of the first edges, so as to attach the second one of the first edges to the second flange by magnetic attraction, thereby suspending the ceiling tile.
