Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/516,268, filed Nov. 3, 2003.
- 1. Field of the Invention
- The present invention relates generally to ceiling fans. More specifically, the invention is a suspended ceiling fan configured to attach to a track attached to a ceiling.
- 2. Description of the Related Art
- Traditional ceiling fans are good at providing an omnidirectional flow of moving air. The operator or user of traditional ceiling fans can only decide the operating status of the ceiling fan. For example, once the traditional ceiling fan is installed, the operator can switch the device on or off, and may be able to set the speed of the device, but the operator has little, if any, control over the direction of airflow produced by the device. Also, traditional ceiling fans are typically complex in construction and suffer from high loads, leading to stress on moving parts. In addition, traditional ceiling fans are designed to be located in one spot and cannot be moved to a different part of a ceiling. Thus, there is a need for a fan of simple construction that can be attached to a ceiling, which can be easily moved to a different location in a room by a user, and which can provide a sustained vectored flow of air that can be aimed at one spot, such as a person's face.
- U.S. application Ser. No. 2003/0082062, published May 1, 2003 and applied for by Chen, describes a multi-rotor ceiling fan comprising a ceiling fan body and a rack body. The ceiling fan body includes a rotatable disk suspended from a support rod. The rack includes a pair of rods extending from opposite sides of the disk, each pair of rods supporting a fan. The fans are positioned so that the airflow generated by the fans causes the disk to rotate. A plurality of electrical contacts about the periphery of the disk maintains electrical power through each pair of rods to drive the two fan motors.
- The Chen '062 device requires at least two rotor fans (and supporting rods) to operate. In addition, the separate rods supporting the rotor fans must be of sufficient strength and durability to support the dynamic weight of the rotor fans and to cope with the rotation forces imposed on the rack body. Further, a user cannot easily move the Chen '062 device to a different location. Still further, short of jamming the rack body the Chen '062 device is unable to produce a sustained flow of air directed at one spot such as a person's face. Also, the burden of requiring at least two rotor fans and sufficiently strong supporting rods adds considerably to the manufacturing cost of the Chen '062 device.
- U.S. Pat. No. 6,364,638, issued Apr. 2, 2002 to Liu, describes a ceiling fan structure that includes a central shaft, a rotary disk having a pivot disk and a pivot base, a support bracket having two pairs of support bars each secured to the pivot base and two locking rings each mounted between two support bars for securing a hanging fan, a conducting power set having a conducting bushing secured on the central shaft, a support base secured on the rotary disk, a plurality of conductors each secured on the support base and each electrically contacting with the conducting bushing for supplying electric power to the hanging fan, a rotation retaining set having a gear secured on the central shaft, a U-shaped support bracket secured on the rotary disk, a support axle mounted in the support bracket, a reduction gear mounted on the support axle and meshing with the gear, a rubbing block mounted on the support axle and urged between the reduction gear and the upper support plate of the support bracket, and a spring mounted on the support axle and having a first end urged on the reduction gear and a second end urged on the lower support plate of the support bracket. Like the Chen '062 device, the Liu '638 device is expensive to manufacture and is unable to produce a sustained flow of air directed at one spot such as a person's face. Further, the Liu '638 device cannot be easily moved to a different location.
- U.S. Pat. No. 5,222,864, issued Jun. 29, 1993 to Pearce, describes a ceiling fan that comprises an electric motor with separate stationary and rotating members. The Pearce '864 device is unable to produce a sustained flow of air directed at one spot such as a person's face and cannot be easily moved to a different location.
- None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. Thus a suspended ceiling fan solving the aforementioned problems is desired.
- The suspended ceiling fan generates a sustained flow of air, which can be aimed at one spot, such as a person's face. In one embodiment, the suspended ceiling fan comprises an elongated member, a track connector, a swivel, and a fan unit. The elongated member has first and second opposing ends. The track connector is attached to the first end, and is adapted for attachment to an existing track, such as a track lighting system, or other support for a suspended lighting system. In one mode of operation the connector snaps into the track. In another embodiment, the ceiling fan comprises an adjustable arm having a hinged joint. The fan may be moved along the track and pivoted on the swivel to direct airflow in any desired direction.
- Accordingly, it is a principal object of the invention to provide a suspended ceiling fan.
- It is another object of the invention to provide a suspended ceiling fan configured to attach to a track on a ceiling.
- It is a further object of the invention to provide a suspended ceiling fan that can be easily moved by a person to a different location.
