发明名称 Quick install blade arms for ceiling fans
摘要 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. The different versions can include guide posts for allowing only one single fastener to be needed. A third embodiment allows the inwardly bendable snapable fasteners to be removable with screws.
