Description
Technical Field
The present invention relates to devices and methods for fan blades and more particularly to devices and methods for covering fan blades that allow the fan blades to be decorated to match a room decor, provides a protective washable cover which is easily removed and installed, provides a means for easily attaching fan blade balance weights and also includes a means for dispensing and distributing room deodorant.
Background Art
Fans and particularly, ceiling fans collect a large amount of dust on their blades and become soiled rapidly as a result of their constant use and rotation. Effective cleaning of fan blades is extremely difficult since very small dust particles become imbedded in the microscopic pores of the fan blade material. Additionally, the difficulty of cleaning ceiling fan blades is compounded since the fans are usually out of reach and the job must be done while dangerously standing on a step ladder or chair.
Another problem associated with ceiling fans is the difficulty of changing the fan's color, such as when a room is redecorated or painted. Usually the only option is to change the ceiling fan, purchase new blades, or disassemble the fan and paint the blades separately.
Still another problem associated with ceiling fans is the difficulty of properly balancing the fan blades so that the fan rotates smoothly at all speeds. Balancing problems can be exacerbated from weight added by painting the ceiling fan blades, clip on deodorant canisters or by adding decorative blade covers.
The present invention solves these problems while also allowing the ceiling fan blades to be employed as room deodorant dispensers and distributors. Deodorant dispensers for rooms are usually cryptically designed to disguise them as common everyday household items such as a toilet paper holder, night light, decorative table top item, and so on. Seeing a room deodorizer is undesirable. Furthermore, these devices are not particularly effective for distributing room deodorant throughout an entire room. A rotating ceiling fan makes an ideal room deodorant dispenser and distributor. Room deodorizers attached to ceiling fans have been patented by Murcin et al., U.S. Pat. No. 5,022,819. The Murcin device attaches an air freshener packet to an existing ceiling fan blade by use of spring loaded U shaped clips. Although, this device extremely useful it is not, and cannot, be incorporated as part of a decorative fan blade cover as the present invention and the Murcin device, can cause the fan to become unbalanced.
Prior devices have been patented which provide covers for ceiling fan blades including Prucha et al, U.S. Pat. No. 4,832,572 which claims an elongated sleeve with an elastic closure at an opened end securing the sleeve on the fan blade. Prucha is an extremely useful fan blade cover, however it cannot provide the multiple uses, such as balancing the fan, and dispensing and distributing room deodorant, as the present invention. Other prior devices relating to ceiling fan blades include a fan blade patented by Junkin, U.S. Pat. No. 5,110,261 comprising a rigid frame covered by a flexible weather resistant cover. McKnight, U.S. Pat. No. 4,753,573 discloses an elongated strip of porous filtering material attached to the top or bottom surfaces of a fan blade. Burt, U.S. Pat. No. 4,889,543 discloses an air filtering system to be interconnected to adjacent blades of a fan by fastening means. Although these devices solve particular problems associated with fans or provide added benefits for fans, the prior devices do not and cannot be adapted to include a fan blade cover which allows the fan blades to be decorated to match a room decor, easily removed for cleaning, while also providing a means for balancing the fan and a means for dispensing and distributing room deodorant.
General Summary Discussion of Invention
It is thus an object of the invention to provide a Fan Blade Cover that provides a protective, durable, easily removed and cleaned cover that allows ceiling fan blades to be cleaned while also providing a means for allowing the ceiling fan blade's color or pattern to be changed to match a room's decor.
It is a further object of the invention to provide a Fan Blade Cover that includes a means for balancing the fan, wherein the means includes a pocket formed on the top surface of the cover near the end of the fan blade which allows weights to be added or deleted from the fan blade as needed to effectively balance the fan.
It is a still further object of the invention to provide a Fan Blade Cover that provides a means for dispensing and distributing room deodorant wherein the means includes a vented deodorant pocket mounted on the bottom side of the blade cover for receiving a rechargeable deodorant canister, while the deodorant pocket and canister includes a visible deodorant depletion indicator, the positioning of the vented deodorant pocket allows air to waft through the pocket vents as the fan rotates thus distributing deodorant throughout the room.
Accordingly, Fan Blade Covers are provided which allows the cover to be easily removed and cleaned while the cover is also supplied in a number of colors and decorative patterns allowing the fan color to be changed to match the room decor as desired, the covers also provide a means for balancing the fan so that the fan rotates smoothly at all speeds wherein the balancing means includes a weight pocket positioned on the upper surface of the blade for receiving multiple weights, the cover also includes a means for dispensing and distributing deodorant wherein a vented deodorant canister pocket is provided on the bottom surface of the cover, while the deodorant pocket and canister also includes a visible deodorant depletion indicator, allowing the user to determine at a glance if the deodorant canister is empty.

Exemplary Mode for Carrying Out the Invention
It can be seen from the preceding description that the covers are made from durable washable material and are produced in a variety of colors, patterns and styles. The covers are constructed to resemble an elongated sleeve with one open end and the other end closed and shaped to resemble the end of a fan blade. The open end of the cover sleeve includes a means for securing the cover once the cover has been slipped over the fan blade. The covers are easily removed and installed which provides a safe means for cleaning ceiling fan blades since the usual method of cleaning fan blades requires a person to dangerously stand on a step ladder or chair. The material used to construct the covers should be machine washable and durable to withstand numerous machine washings. The covers include a means for balancing the fan by adding or deleting weights from a pocket positioned on the upper surface of the cover. The balancing means allows the fan to be balanced after attaching the covers which may be necessary since the covers add weight to the fan blades. The covers also include a means for dispensing and distributing deodorant throughout a room, wherein a vented pocket is positioned on the bottom surface of the cover which receives a deodorant canister, so that as the fan rotates moving air wafts through the vented pockets distributing scented air throughout the room. When the deodorant in the canister is depleted a visual deodorant depletion indicator alerts the user to add more scent to the canister.
FIG. 1 illustrates a typical ceiling fan 10 with four fan blades 12 and the positioning of the fan blade cover 20 over one of the fan blades while the fan balancing means 30 is positioned on the upper surface of the cover and the deodorant dispensing and distributing means 40 is positioned on the bottom surface of the cover 20.
The cover 20 is constructed to resemble a sleeve with a closed end 21 and an opened end 22 for slipping over the fan blade. The material used to construct the cover is preferable a washable fabric such as SPANDEX.sub..TM. which slips over the fan blade tightly. Other fabrics can also be used, such as cotton, nylon, and other synthetics, however the fabric used preferably does not shrink in normal machine washing and further is durable and has good dye retention. The fabric used may also include numerous colors, patterns and designs if desired so that covers can be chosen to match the room decor. The closed end of the cover 21 is secured by stitching while the open end 22 edges are also stitched to prevent fraying. The open end 22 also includes a means for securing the covers 20 on the fan blades. The securing means preferably includes two elongated fabric tabs 23 which extend from the cover bottom surface 24 and once the cover 20 is installed over a fan blade 12 the tabs wrap around the fan blade post end 13 and secure to the cover top surface 25 by use of VELCRO.sub..TM.. The cover open end 22 includes an indented section 26 which allows the cover 20 to be pulled up to the fan blade shaft 14. There may be other tab securing means other than VELCRO.sub..TM. such as buttons and snaps. The securing means is not seen on the typical ceiling fan since the tabs 23 are attached on the top surface 25 of the cover 20 and the top surface 25 faces the ceiling of the room where the fan is installed.
As illustrated in FIG. 3 the fan balancing means 30 includes a pocket 31 attached to the top surface 25 of the cover and formed as an integral part of the cover material. The pocket 31 includes an upper flap 32 and a lower flap 33 forming a space for receiving balancing weights 34. The flaps are preferably secured using VELCRO.sub..TM. 35, while other securing means may be employed such as snaps and buttons. The flaps 32 and 33 are orientated to form an opening for entering the pocket in a direction which does not allow the weights 34 to exit the pocket 31 when the fan is rotating and forcing the weights to sling to the end of the fan blade. Additionally, the dimensions of the pocket 31 allow a multiplicity of weights to be placed in the pocket. The weights 34 used are preferably flat lead weights and may be formed to fit within the pocket 31 or may be cut to reduce weight added in a given pocket. The fan is balanced after all the covers 20 have been placed on all the fan blades, and further after the deodorant means 40 is also installed and loaded with deodorant. Balancing is accomplished by adding or deleting weights on each fan blade as needed.
The deodorant dispensing and distributing means 40 includes a vented pocket 41 which is positioned on the bottom surface of the cover 24 and is constructed of preferably meshed material with numerous pores 45 which is sewed directly onto the cover 20. The vented pocket 41 is also equipped with a VELCRO.sub..TM. sealed flap 42 for sealing the vented pocket 41 after a deodorant canister 44 has been installed in the pocket 41. The deodorant canister 44 is a low profile oval plastic container with an interior reservoir 46 for storing scent. The interior is filled with absorbent material 47 which absorbs liquid scent and prevents the liquid scent from leaking from the canister inadvertently. The canister 44 is filled with liquid scent through filling aperture 48 which is located on the top of the canister 44. The liquid scent is wicked from the canister 44 through wick 49 which is in communication with the interior absorbent material 47 and while the other end of the wick is exposed to air which travels through the mesh material as the fan rotates. The wick 49 is preferably composed of felt material and may also be foam, spun cotton, or other material known to be highly absorbent. The absorbent material must also be inert to the liquid scent used. The canister 44 includes visual depletion indicators 50 which are visible from the bottom side 51 of the canister 44. There may be one or more visual depletion indicators. The depletion indicators change color or tint as the canister contents are depleted alerting the user of the fan and the covers that the deodorant should replenished. Liquid scent of any type may be used as long as the scent does not deteriorate the absorbent material.
