COVER FOR CEILING FAN BLADES AND MiOTOR HOUSING
BACKGROUND OF THE INVENTION
Field of the invention
This invention relates generally to ceiling fans but more particularly to
removable
covers for blades and motor housing.
Background
Ceiling fans are very useful and practical to have as they procure air
circulation and an
appreciated cool breeze on a hot day or night. Unfortunately, the top side of
the blades
of those fans tend to accumulate a lot of dust, especially when they are not
used over
long periods of time. In situations where a ceiling fan is located in or near
a kitchen,
airborne grease or oil, such as produced when cooking, can settle onto the top
of the
blades and the dust that follows will stick on that greasy surface and
compound the
problem.
Cleaning those blades is not the most appreciated of chores so, in order to
facilitate
this, a number of inventors have come up with the concept of removable,
washable
cover liners for ceiling fan blades. Unfortunately, in some cases., it appears
that fitting
those covers over the blades is as unpleasant an activity as cleaning them.

A second application found for ceiling fan blades is to use the rotating
action of the
blades as a vehicle to move air filters or deodorizers to clean or deodorize
the room.
Given that a rotating ceiling fan tends to stir up airborne particles, it is
only normal that
adding filters to blades would catch even more airborne particles. However,
the way
these filters are implemented on the blades of the prior art makes them bulky
or, when
put perpendicular to the flat of the blade, tends to reduce aerodynamic
characteristics
of the blades and potentially adds strain on the motor, which could result in
its
shortened lifespan.
Given these drawbacks, it is easy to understand that there is still room for
an improved
system for covering ceiling fan blades which doubles as an air filter.
SUMMARY OF THE INVENTION
One object of the present invention is to provide for removable covers for
ceiling fan
blades.
A second object of the present invention is to provide for removable covers
for ceiling
fan motor housing and ceiling connector parts.
A third object of the present invention is to provide a filtering system
incorporated with
the blade covers.

A final object of the present invention is to provide a set of disposable
blade covers
that obviate the need for washing them.
In order to do so, the invention has blade covering material all the way up to
the stem
and on the backside of the blade covering material is a zipper to allow one to
install
said sleeve of blade covering material. Other improvements such as a ceiling
cover
cap snapped onto an existing cover by way of tabs; and the ceiling connector
covering
material being wrapped around and secured using hook and pile fasteners.
The foregoing and other objects, features, and advantages of this invention
will
become more readily apparent from the following detailed description of a
preferred
embodiment with reference to the accompanying drawings, wherein the preferred
embodiment of the invention is shown and described, by way of examples. As
will be
realized, the invention is capable of other and different embodiments, and its
several
details are capable of modifications in various obvious respects, all without
departing
from the invention. Accordingly, the drawings and description are to be
regarded as
illustrative in nature, and not as restrictive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 A cover for ceiling fan blades and motor (10) is seen as installed on a
typical
ceiling fan (12). A typical ceiling fan (12) having blades (14), a motor
housing (16} and
a ceiling connector (18).
FIG. 2 The front view of a blade (14) shows how a sleeve of blade covering
material
(20) can cover an entire blade (14) all the way up to the stem (22).
FIG. 3a On the backside of a blade (14) the sleeve of blade covering material
(20) has
a zipper (24) which allows one to install the sleeve of blade covering
material (20)
much like one puts on a pair of pants.
FIG. 3b The zipper (24) incorporates a hook and pile fastener onto which is
releasably

attached a piece of disposable air cleaning material (26). The air cleaning
material (26)
can use adhesive properties to trap airborne dust or else, it can use known
properties
that some type of material have to attract and called dust particles by way of
ionisation
through static electricity which is enhanced by the moving blades (14).
FIG. 4ab In order to cover the motor housing (16) and the ceiling connector
(18), a
ceiling cover cap (28) is snapped onto the existing cover (30) by way of tabs
(32) as
well as by reusing a screw (34) that usually connects the cover (30). (7nce
this ceiling
cover (28) is in place, the ceiling connector covering material (36) is
wrapped around
and secured using hook and pile fasteners.
FIG. 5ab In order to cover the motor (16), two pieces are necessary: a
circumferencial
piece of fabric (38) having rubber bands (40) which is held snugly around the
motor
housing (16) and an underside cover (42) which is slipped underneath the
circumferential piece of fabric (38).
