Guy wire connector for ceiling fan

An apparatus for connecting one or more guy wires to a down rod, the connector having first and second separable portions which form an aperture for receiving the down rod. At least one of the first or second portions includes at least one passage adapted for releasably receiving a portion of the guy wire. The guy wire may include an anchor, and the passage for receiving the guy wire may be adapted for capturing the anchor so as to preclude movement of the guy wire in a radial direction.

Ceiling fan with mounting plate

A ceiling fan assembly having a motor with a rotor and a stator, at least one blade operably coupled to the stator, a motor shaft extending from the stator and having an internal wire passage and a wire opening in a side of the motor shaft, with the wire opening providing access to the internal wire passage, a control mounting plate having a motor shaft opening through which the motor shaft extends and an electronic control unit carried by a side of the control mounting plate.

Ceiling fan mounting assembly

A ceiling fan assembly or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can further include a hanger ball with an indexing pin. The ball hanger can be received by a mounting bracket so that, via an alignment guide, the indexing pin of the hanger ball aligns with an indexing groove on the mounting bracket.

A ceiling fan structure includes a mounting bracket, a hanging plate, a coupling, and a motor. The mounting bracket is fixed to a ceiling. The hanging plate has a top fixed to the mounting bracket. The top is formed with a recessed accommodating groove for accommodating a first electronic component. The coupling is connected to a bottom of the accommodating groove and extends downward. The coupling is connected with a support plate extending horizontally. The support plate is configured to support a second electronic component. The internal space of the ceiling fan structure is properly planned so that the components of the ceiling fan structure can be reasonably configured, so as to improve the efficiency of assembly.

Extractor fan assembly with clamshell hub

An extractor fan assembly for an extractor of a sugarcane harvester comprises a motor, fan blades, and a clamshell hub. The motor comprises an output that rotates about an axis of rotation. The clamshell hub comprises a base and clamp jaws. The base is coupled to the output for rotation therewith about the axis of rotation. The clamp jaws are positioned angularly about the axis of rotation. Each clamp jaw is fastened to and cooperates with the base to clamp a respective fan blade of the fan blades therebetween to position the fan blades angularly about the axis of rotation.

A ceiling fan mount assembly having a downrod assembly with a downrod and a motor assembly comprising motor and including a motor shaft. The ceiling fan mount assembly further includes a downrod plate coupled to the downrod and a shaft coupler coupled to the motor shaft and coupled to the downrod plate, whereby coupling the downrod plate to the shaft coupler suspends the motor from the downrod.

Variable pitch vane control ring bush retention foil and turbojet containing same
20180003193 · 2018-01-04 ·

A flexible metal foil can be fixed on the inside part of a variable pitch vane control ring of a turbojet compressor, so as to close all through holes in which lever pins and their surrounding bushes are housed. As a result, the foil can retain the shank of the bush if the bush breaks. The use of such foil does not impose the development of a new model of control ring and its impact on the mass is small enough so that it does not affect engine performances. Therefore it avoids problems related to the breakage of bushes without having to make major changes to the existing system.

WEARABLE BLOWER AND ASSEMBLY
20180000014 · 2018-01-04 ·

An assembly including a wearable blower having a fan, a motor, an air duct having a duct housing thereof, a handle attached to the duct housing, and a hanger disposed on the duct housing. The hanger has an attachment part attached to the duct housing and adjacent to the handle and a hanger part connected to the attachment part for holding an accessory attached to the blower. The hanger part rotates with respect to the duct housing at a first hanging position whereat the hanger part is unfolded with an opening mouth for holding the accessory of the blower and the hanger part rotates with respect to the duct housing at a second folded position. Thus, the arrangement of the hanger can help the user to hold the accessory of the blower at the work states.
