Abstract: Quick attachable and detachable mounting arms for ceiling fans. A first version has flat headed fasteners initially attached to one end of mounting arms, with key-hole slots in the endshield of the ceiling fan motor. The user raises the mounting arm so that the flat headed fasteners fits through the larger openings in the keyhole slots and then pulls the mounting arm outward until the arm locks in place by the smaller opening portions of the keyhole slots. Rubber type gaskets and washers help lock and hold the mounting arms in place. The flat headed fasteners can also be located on the endshields with the keyhole slots on mounting arms. A second embodiment includes inwardly deformable springably snapable Fasteners that can be located on the ends of the mounting arms which can deform inwardly and expand after passing through slots on the endshield of the rotor. Alternatively, the fasteners can be located on the bottom of the endshield with the receiving slots on the ends of the mounting arms.

Abstract: Lamp devices, apparatus, methods of use, and methods of assembly which can be used with a single suspension lamp and/or with a plurality of suspension lamps. Each lamp can have a lamp seat mounted on a tubular member that is fixed to a main body. The lamp seat can be connected electrically to a circuit unit housed in the main body, and is mounted with a lamp bulb. A bowl-shaped upper lamp shade surrounds the lamp seat, is mounted on the tubular member, and is formed with heat-dissipating holes. A lower lamp shade is coupled detachably to a larger-diameter lower open end of the upper lamp shade, and cooperates with the upper lamp shade to define an accommodating space for receiving an assembly of the lamp seat and the lamp bulb. A bowl-shaped water-resistant cover is mounted on the tubular member, and is disposed above the upper lamp shade for covering the upper lamp shade.
