Abstract: An assembly of a blade assembly bracket and a blade of a ceiling fan includes a blade assembly bracket, an adaptor, and a fan blade. The adaptor is pivoted to the blade assembly bracket, and the fan blade is pivoted to the adaptor. When the adaptor is pivoted relative to the blade assembly bracket, the adaptor can drive the rotatable holder simultaneously to switch a position of the fan blade between an initial position and a rotational position, so as to change an inclination angle of the fan blade, and make the fan blade unfold outwardly. When the operation of the ceil fan is stopped, the adaptor is operated reversely to make the fan blade fold from the outwardly-unfolded state.

Abstract: A ceiling fan with an oscillating mechanism includes a clutch member for adjusting the angle of oscillation according to a user's need. When the motor is actuated, the rotating torque induced by the motor and the transmission mechanism is less than the rotational resistance of the clutch member such that the motor may drive the fan to oscillate. Further, when the user applies an external rotational force greater than the rotational resistance of the clutch member, the user can swing the fan to any angle as desired without rotating or shifting other members except the fan and the fan suspension tube. In this manner, undesired damage of the mechanism or motor due to inappropriately applied external force can be avoided efficiently.

Abstract: A ceiling fan lighting system includes a fan assembly, a light assembly and a lift mechanism. The fan assembly includes a motor and a plurality of fan blades being operationally coupled to the motor to permit rotation of the fan blades when the motor is supplied with power. The light assembly is coupled to the fan assembly and has at least one light source and a lamp shade enclosing the light source. Moreover, the lift mechanism is configured to move the light assembly in a vertical plane with respect to the fan assembly in order to have the lamp shade of the light assembly enclose or disclose the fan blades of the fan assembly.

Abstract: A blade structure and ceiling fan having the same are disclosed. The blade structure includes a blade root, a blade tip, and a first vertex and a second vertex between the blade root and the blade tip. The blade bends from blade root to the first vertex, the blade tip and then bends from the blade tip to the second vertex and back to the blade root to form a hollow structure. The ceiling fan with the blade structure not only provides air modulating function but also has unique modeling.

Abstract: A fan device having simultaneously foldable blades includes a rotatable driving unit. A plurality of supporting frames extend outwardly from the driving unit, each supporting frame has a pivot mounted on one end thereof. A plurality of shells are respectively mounted on the supporting frames, each shell has a center hole defined therein. A plurality of blades are respectively disposed on the shells. Each blade has an assembling portion disposed thereon. Each assembling portion has a through hole defined therein. A plurality of coupling rods respectively positioned between every two adjacent shells. When the driving unit rotates, the shells synchronously rotate and driving the coupling rods to be moved for simultaneously driving the blades to retractably fold/unfold.

Abstract: A cooling fan structure includes a driving device having a rotatable section disposed therein for providing a rotatable effect. The rotatable section has a first end longitudinally extending to a top of the driving device and a second end longitudinally extending to a bottom of the driving device. A set of fan blades is radially mounted to the rotatable section of the driving device and driven by the rotatable section. Each fan blade has an inner end. The inner end has a first connection and a second connection respectively extending therefrom. The first connection of each fan blade is connected to the first end of the rotatable section. The second connection of each fan blade is connected to the second end of the rotatable section.

Abstract: A blade assembly for a ceiling fan includes a mounting arm, a bearing, a cover, a spiral spring, a blade, and three screws. The mounting arm has a plate. The plate has a boss. The boss has a split. The bearing is sleeved on the boss. The cover has a stub. The stub has a receiving recess for receiving the bearing. The cover has a through hole for passing the boss. The cover has three bosses. The spiral spring has one end sleeved on the boss of the cover and the other end engaged with the split. The blade has three mounting holes and corresponding to the boss of the cover. The three screws pass through the mounting holes and fasten with the bosses of the cover.

Abstract: An advertising ceiling fan includes a motor seat, a plurality of blade support brackets, and a plurality of support tubes. Each of the blade support brackets is secured with a sleeve having two through holes. Each of the support tubes has one end formed with two positioning holes each aligning with a respective through hole. Each of the support tubes includes two elastic members each having a first end formed with a protruding stub extended through a respective one of the two positioning holes and a respective one of the two through holes. Thus, the support tube is mounted on and detached from the respective blade support bracket easily and conveniently, thereby facilitating quick replacement of the advertising paper.

Abstract: A ceiling fan housing assembly includes an upper casing mounted on the top of a motor, a fastener mounted on the bottom of the motor and a lower casing attached to the fastener. The fastener includes an annular flange laterally extending from the fastener and multiple equally spaced threaded holes defined in the annular flange. A bracket extends from the flange and a reversing switch is mounted on a free end of the bracket. The reversing switch has a switch bar that extends through the housing assembly. The lower casing abuts the upper casing to form a chamber to hold the motor. The lower casing includes multiple equally spaced through holes defined in the bottom of the lower casing, and a slot is defined in of the lower casing to allow the switch bar of the reversing switch to extend through the lower casing.
