  • REFERENCE TO MICROFICHE APPENDIX
  • Not applicable.
  • FIELD OF THE INVENTION
  • The invention relates generally to fans, and in particular to ceiling fans. The invention further relates to a ceiling fan blade attachment mechanism.
  • BACKGROUND OF THE INVENTION
  • A typical ceiling fan includes a down rod assembly suspended from the ceiling with a motor shaft which is connected to a lower portion of the down rod assembly. A motor body rotates about the motor shaft. A motor housing which surrounds the motor may be secured to either the motor shaft or the down rod assembly, which remain stationary. Blade mounting arms, also referred to as blade irons, are connected to the motor body and extend out of an opening of the motor housing or below the motor housing. A hub is attached to the motor shaft below the fan blades and blade irons.
  • A conventional ceiling fan blade typically consists of a solid unitary member of wood, metal or plastic, or a frame with a covering made of nylon or some other suitable material. In both cases, however, the blade is usually attached to the fan motor by means of a standardized mounting structure commonly referred to as the blade iron. The prior art provides numerous examples of fan blades that are attached to the fan motor with the aid of a blade iron. In a typical ceiling fan, the fan blade must first be attached to the blade iron, which in turn must be attached to the motor housing.
  • Conventional blade irons used in the art tend to be discrete structures that are separable from the fan blades and the fan housing. Typically, conventional blade irons are connected to their respective fan blades via their distal ends and are connected to the fan motor or motor housing via their proximal ends. Conventional blade irons are often decorative in nature and are used primarily to enhance the overall appearance of the ceiling fan rather than in a utilitarian role. In other words, conventional blade irons are not always critical to the operational ability of ceiling fans.
  • The use of a conventional blade iron to attach a fan blade to a fan motor can add to the cost of the fan's manufacture and make it more expensive for purchase by a consumer. In addition, the presence of a blade iron can add to the weight of a fan, and thereby make it less efficient from an energy consumption stand point. Additionally, it is a common commercial practice for ceiling fans to be shipped to the end user in an unassembled state. Therefore, a ceiling fan requires assembly prior to installation. This often challenging task can be made easier if the ceiling fan blades are capable of being easily connected to the rest of the ceiling fan unit. Furthermore, there are a variety of reasons for removing fan blades from the motor housing, for e.g., when the fan motor is in need of maintenance or repair, and when the motor housing and fan blades must be cleaned.
  • Accordingly, it would be desirable to have a ceiling fan blade attachment mechanism where the ceiling fan blades are capable of being connected to a fan motor by a mechanism that is easy and convenient to the consumer. It would also be desirable to have a ceiling fan blade attachment mechanism that provides an easy and convenient way to assemble and dissemble fan blades from the motor housing.
  • SUMMARY OF THE INVENTION
  • An embodiment of the invention provides a ceiling fan suspended by a down rod, the fan comprising a motor housing that rotates relative to the down rod, a plurality of fan blades, wherein each fan blade comprises a first attachment member, a second attachment member that is connected to the motor housing, wherein the second attachment member comprises a sleeve that is capable of receiving the first attachment member, and a mechanism for securing the first attachment member in the sleeve of the second attachment member.
  • Another embodiment of the invention is directed to a fan comprising a motor having a motor shaft and a motor body that rotates relative to the motor shaft, a motor housing rotatable with and connected to the motor body, an attachment member connected to the motor housing, wherein the attachment member comprises a slot, into which a fan blade is inserted and secured using an attachment mechanism.
  • An aspect of the invention is directed to a method of installing a fan blade, the method comprising aligning the fan blade with a sleeve in an attachment member, wherein the attachment member is connected to a motor housing, inserting the fan blade into the sleeve, and positioning the fan blade in the sleeve to allow an attachment mechanism to secure the fan blade in the sleeve when the fan blade is properly positioned in the sleeve.
  • Another embodiment of the invention is directed to a ceiling fan comprising a motor having a motor shaft and a motor housing that rotates relative to the motor shaft, the motor housing comprising a plurality of attachment members, and a plurality of fan blades, each blade secured to the motor housing via an attachment mechanism, wherein the attachment mechanism connects to one of the plurality of attachment members.
