Abstract

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.
