A recently granted patent (Publication Number: US11879250B2) discloses a panel assembly designed for a suspended ceiling system. The assembly includes a ceiling panel with a groove on the rear surface, suspension bars that fit into the groove, and adjustable corner brackets that can be positioned along the corners of the panel. These corner brackets can be altered to change the angle between the first and second arm axes, ensuring a secure fit within the suspension bars. The design allows for flexibility in adjusting the angle within a specified range, preventing the angle from going below a minimum of approximately 30° or above a maximum of 220°. Additionally, the panel assembly features hook members that can be attached to the suspension bars to hang the panel from an overhead grid assembly.

The method of assembling the panel assembly involves adjusting the corner brackets to match the interior angle of the polygon-shaped groove on the ceiling panel and inserting them along with the suspension bars into the groove. The corner brackets can be modified to achieve the desired angle between the arm axes, ensuring a secure and stable installation. The method also includes attaching hook members to the suspension bars for hanging the panel assembly from the overhead grid assembly. Furthermore, the patent details the specific design of the corner brackets, with first and second arm components that can be adjusted to prevent the angle from exceeding the specified limits, providing a reliable and customizable solution for suspended ceiling systems.
