Abstract: A fan assembly according to which a block member is connected to a rotor end casing and an arm member having a blade connected thereto is mounted to the block member. One of the members has a radially extending slot formed therein and the other member has a mounting flange adapted to extend into the slot when the arm is moved radially outwardly relative to the block member to mount the arm to the block member without the need for additional components.
Abstract: A fan blade assembly and method according to which a mounting arm is provided and at least one clamping member extends from the arm. A blade has a portion engaging the arm, and a through opening for receiving the clamping member. The clamping member is movable to a clamping position to clamp the blade to the arm.
Abstract: A fan assembly and a method of assembling same according to which a mounting flange is provided on an arm to which a blade is connected and a slot is provided in the rotor end casing of the fan motor. The flange is inserted in the slot and a wedge is created between the flange and the surface of the end casing defining the slot to secure the arm, and therefore the blade to the end casing.
Abstract: A fan assembly and a method of assembling same according to which a mounting flange is provided on an arm to which a blade is connected and a slot is provided in a mounting ring. The flange extends in the slot, and a retainer engages the arm member. The retainer and the mounting ring are attached the end casing and a post is provided in the slot for extending in a bore formed in the flange.

Abstract: A ceiling fan assembly and method for assembling same in which a fan blade is placed over an arm having a post that extends in an opening in the blade. A fastener is attached to the post to secure the blade to the arm, and a flange on the arm is inserted in a slot in the rotor of the fan motor to retain the arm, and therefore, the blade, relative to the rotor.
Abstract: A one-piece injection molded arm and blade unit for a ceiling fan, or the like, in which a blade forms an extension of an arm. At least one web formed on the arm, and at least one other web is formed on the arm and extends at an angle to the first web. The webs serve to add strength to the unit to counteract the various stresses placed on the unit during operation.
