A ceiling fan hanger assembly includes a mount plate with a pair of plate extensions and a downrod having a pair of spaced downrod extensions. A connector bracket pivotally couples to the plate extensions to define a first pivot axis and pivotally couples to the downrod extensions to define a second pivot axis different than the first pivot axis.

A ceiling fan blade fastening structure includes a base and a fan blade. The base is fixed to a rotor of a motor of a ceiling fan. The base has a bottom wall and a peripheral wall. The peripheral wall has a slot. The bottom wall is provided with a guide rail portion adjacent to the slot. The bottom wall is provided with a bracket and a positioning block behind the guide rail portion. The fan blade has a tongue portion to be inserted into the slot and pressed against the positioning block, so as to position the fan blade. The tongue portion is provided with a stop block to be against the rear of the bracket, so that the fan blade is unable to be disengaged from the slot.

An air moving device includes a housing member, an impeller assembly, and a nozzle assembly. The nozzle assembly can include one or more angled vanes set an angle with respect to a central axis of the air moving device. The air moving device can output a column of moving air having an oblong and/or rectangular cross-section. A dispersion pattern of the column of moving air upon the floor of an enclosure in which the air moving device is installed can have an oblong and/or rectangular shape. The dimensions of the dispersion pattern may be varied by moving the air moving device toward or away from the floor, and/or by changing the angles of the stator vanes within the nozzle assembly.

A ceiling fan assembly can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can include a ceiling fan mount with a canopy. The canopy can be received by a mounting bracket to enclose the mounting hardware near the ceiling.

Embodiments of the present invention provide systems and methods for mounting an electrically-powered device to a ceiling or other supporting structure. The electrically-powered device can be, for example, a ceiling fan, a ceiling fan with a lighting fixture, or a lighting fixture.

A concealed office fan lamp is provided, which includes a stop device, a support and a fan blade. A lamp is arranged at the bottom of the support, a cavity is arranged in the support, the fan blade is electrically connected with a driving mechanism to make it rotatably arranged in the cavity, and the stop device is arranged on the support and/or the fan blade to detect the motion state of the fan blade. According to the motion state, the fan blade is stopped and hidden in the cavity. By providing a stop device on the fan lamp, the fan blade can be accurately stopped and hidden in the cavity, the person under the fan lamp cannot see the fan blade when the fan lamp stops working, making the fan lamp more beautiful as a whole.

A temperature destratification assembly can include an outer housing. An impeller can be positioned within the outer housing between the inlet and outlet of the outer housing. The impeller can have an impeller hub and a plurality of impeller blades extending radially outward from the impeller hub. The assembly can include an impeller motor configured to rotate the impeller blades about an axis of rotation. A stator can be positioned within the outer housing between the impeller and the outlet of the outer housing. The stator can include a plurality of vanes. The stator vanes can include an upstream edge at the upstream end of the stator, a first surface extending from the upstream edge to the downstream edge of the vane, and a second surface opposite the first surface and extending from the upstream edge to the downstream edge of vane. A plurality of the vanes can have a downstream edge at the outlet of the outer housing.

A ceiling fan having a dual redundant motor mounting assembly for suspending a motor comprising a downrod, a hollow motor shaft suspending the motor from the downrod, a retaining pin extending through the hollow motor shaft, and a retaining rod coupled to the retainer pin for redundantly suspending the motor.

A ceiling fan light kit and a ceiling fan connecting module are provided. The ceiling fan light kit includes the ceiling fan connecting module, a light board, and a light cover module. The ceiling fan connecting module includes a mounting plate and a base. The mounting plate has a plurality of arc holes, a plurality of rotary fixing structures, and a plurality of backstop structures, and a placing hole and a fixing hole are respectively formed at two ends of each of the arc holes. The mounting plate has one of the rotary fixing structures and one of the backstop structures that are spaced apart from one another formed at two sides of each of the arc holes. The base has a bottom plate, a cooling portion, and a plurality of dowels that are respectively disposed in the placing holes.

A fan blade apparatus for use in a high-volume, low-speed fan wherein the fan blade includes a body portion, a leading edge portion and a trailing portion. The fan blade coupled to an electric motor configured to rotate in an intended direction wherein the leading portion of the fan blade is at the forefront of the rotation of the blade. The leading edge portion of the fan blade includes a series of steps extending along the length of the leading edge. The stepped configuration creates turbulent air flow when the electric motor rotates in the intended direction.
