发明名称 Blade spreading assembly for quick ceiling fan installation
摘要 A blade spreading assembly for quick ceiling fan installation is disclosed. The blade spreadingassembly comprises a fan rotor bracket attached to the fan rotor and operatively coupled to an arm which connects to fan blade. The assembly allows the attached fan blade to collapse for storage and shipment and spread for operation. Since the blades are pre-attached by the manufacturer, the user is only required to unpack the ceiling fan from the shipment box and hang the fan up at a desired location and have the fan blades spread out with a simple single push. The fan blades can likewise be collapsed for storage with relative ease.
