A hinge assembly is designed to reduce the number of details in the hinge assembly and to simplify the construction of the hinge assembly. The hinge assembly includes an arm having a length with a pivot post on a first end of the arm and an arm lock on an opposite second end of the arm. An internally screw threaded hole extends through the arm block. The plate is attached to the second end of the arm. The plate has a plate surface configured for attachment to a ceiling panel and an opposite adjustment surface. A ridge extends across the adjustment surface and a slot extends through the ridge. The arm block is positioned adjacent the ridge with the internally screw threaded hole of the arm block aligned with the slot through the ridge. An externally screw threaded rod extends through the slot and is screw threaded into the internally screw threaded hole through the arm block. The externally screw threaded rod is turned in opposite directions to alternatively lock the arm to the plate, and release the arm from the plate for adjustable positioning of the plate relative to the arm.
