A suspended ceiling system having a trim strip and ceiling runners. A trim connector fastens the trim strip to the ceiling runners. The trim connector being a two part structure is fastened to the trim strip by a releasable fastening action. One of the two parts of the trim connector is also fastened to the ceiling runner.

Runner-trim connector

The universal attachment clip will act as an attachment device for attaching micro cornice trim to each of the major grid systems. The clip will allow attachment and registration of each of the micro cornice trim profiles to 9/16', 15/15', or bolt-slot grid. The registration of the micro cornice profiles to the grid can be at different angular positions.

Micro cornice universal attachment clip

A combination is disclosed wherein an inverted T-shaped ceiling runner is connected to a decorative element by a connector. The decorative element has parallel grooves into which an upper portion of the connector can be positioned in the grooves to hold the connector relative the decorative element. A lower portion of the connector extends down to the inverted T-shaped ceiling runner and is fastened to the vertical web thereof to position and hold the decorative element in a fixed relationship to the inverted T-shaped ceiling runner.

Connector

A clip for retaining a metal ceiling panel in position relative a ceiling runner. The clip will fasten to the horizontal flange of a ceiling runner or the lower end of the wall molding supporting a cut edge of a metal ceiling panel adjacent a wall structure.

Ceiling clip

The safety mechanism will act to provide a security device which will prevent a kerfed ceiling panel from falling to the floor if the panel is disengaged from the grid system due to improper installation, seismic event, or other reasons. The mechanism is designed to use a retractable hook structure which moves from an inactive position prior to installing the ceiling tile to an active position where the hooked mechanism will be able to engage the vertical web of the runner of the grid system to prevent a disengaged ceiling panel from falling out of the grid system to the floor of a room.
