Automatic eyewear cleaner
Abstract
An automatic eyeglass cleaner is provided in accordance with the
invention. A specially formulated cleaning and conditioning
solution is also provided for use with the automatic cleaner. A
tank in the automatic cleaner is filled with the cleaning and
conditioning solution; the eyeglass is folded up and clipped to the
bottom of the open lid of the cleaner, then the lid is closed to
lower the eyeglass into the solution. The cleaning cycle starts
with the push of a button and the eyeglass is agitated in the
solution. The cleaning cycle stops automatically after a pre-set
time, the lid pops up and any excess solution is shaken off the
eyeglass by the cleaner leaving a thin film on the lenses. A
microfiber cloth is used to give the lenses a final touch-up that
helps fill in microscopic scratches.

Description
PRIORITY CLAIM
[0001] This application is a continuation of U.S. patent
application Ser. No. 10/761,839, filed Jan. 21, 2004 entitled
"Automatic Eyewear Cleaner" (Attorney Docket No. SHPR-01404US1),
which claims priority to U.S. Provisional Application No.
60/490,671, filed Jul. 29, 2003 entitled "Automatic Eyewear
Cleaner" (Attorney Docket No. SHPR-01404US0), both of which
applications are hereby incorporated by reference.
FIELD OF THE INVENTION
[0002] The present invention is directed to a system and method for
cleaning eyewear.
BACKGROUND OF THE INVENTION
[0003] Whether they are for vision correction, vision protection or
simply used as a fashion accessory, eyewear has long been a
popular, if not indispensable, personal accessory. There are
specialty eyewear which includes a wide range of eyeglasses and
sunglasses that are designed for a specific purpose, such as
computer use, driving, work, hobbies, eye protection and more. A
huge variety of frames are available for prescription eyeglasses or
sunglasses. Not only are there many different shapes and colors in
eyeglass frames, but advances in technology have also brought a
variety of new materials, for both the frames and the lens, which
makes eyeglasses more durable, lightweight and comfortable.
Eyeglass frames are now created from high-tech materials such as
titanium and memory metals, while the lens are now thinner and
lighter than ever before, even for high prescriptions. Lens
coatings, including scratch-resistant coatings, ultraviolet
treatments, anti-reflective coatings and mirror coatings, are
commonly added to the lens to enhance their performance and
appearance.
[0004] These high-tech frames and coated lens are expensive and are
worth protecting. Unfortunately, the lens (even scratch-resistant
coatings are not scratch-proof) can easily be damaged by casual
cleanings by the wearer, leaving the lens with a unsightly
scratched surface that can hinder vision. As any eyewear user
knows, eyewear can require cleaning with just a short time of wear.
Because of the eyewear's close contact to the wearer, body oils,
sweat, grime and dead skin cells gets trapped in the lens and frame
and accumulate in little time. Dust, dirt and fingerprints on the
lens add to this unwanted mess. Further, the metal finish of frames
can corrode and become discolored from prolonged exposure to sweat,
which is acidic in nature.
[0005] Wiping the eyewear with tissue paper or the corner of a
shirt is a common practice for many eyeglass wearers. However,
ordinary tissue paper and many types of cloths are highly abrasive
because of their coarse fibers. Wiping the lens with these often
lead to irreparable damage to the coating. Small, hard particles
such as sand may also be deposited on the lens, and a simple wiping
may be akin to polishing the lens with sandpaper.
[0006] Non-abrasive Micro-fiber Towels, with each strand of fiber
being made of hundreds of micro-fibers (on the scale of 90,000
micro-fibers per sq. inch) have been gaining popularity in eyeglass
care. These micro-fibers act to attract and hold dirt and grime,
and can retain up to seven times its weight. The cloth used in
micro-fiber towels is made of a matrix of polyester and polyamide
weaved in such a way as to create a "dinginess" that picks up dirt.
However, these towels are unable to reach tiny nooks and crannies
of the eyeglass frame, and do not counteract the acidic corrosion
of sweat. Further, because the cloths trap and hold grime, they get
dirty very quickly and lose their effectiveness without frequent
laundering.
[0007] Ultrasonic cleaners, such as the one taught in U.S. Pat. No.
4,114,194, have long been known in the field of professional
jewelers and optometrists. The ability of a liquid when
ultrasonically agitated to penetrate small spaces and, by
cavitation, to remove foreign matter from solid objects has led to
the wide use of ultrasonic cleaners in laboratories and industry.
However, it is discovered that the use of ultrasonics tends to
break down and remove the coating on the lens.
[0008] U.S. Pat. No. 5,988,910 teaches an eyeglass cleaning
apparatus with a pair of lens engaging rollers made of soft web
material mounted on a handle. A lens is passed between the rollers
and the rollers are rotated to clean the lens simultaneous on both
sides. The handle includes a pump for spraying cleaning solution on
the lens prior to operation. This device cleans only one lens at a
time, and requires constant movement by the user to cover all
corners of a lens. Further, it is not designed specifically with
cleaning the frame in mind.
SUMMARY OF THE INVENTION
[0009] An automatic, motorized eyewear cleaner is provided in
accordance with an embodiment of the invention. The cleaner can
clean practically any pair of eyeglasses by agitating them in a
specially formulated cleaning solution, and then automatically
drying them. The entire process from start to finish should take
only about one minute.
[0010] It is, therefore, an object of this invention to provide an
automatic device that can effectively and safely clean all manner
of eyewear, regardless of whether the frame is plastic or metal,
whether the lens are glass or plastic, or whether the lenses are
coated or not. The device should be able to clean most shapes and
sizes of frames and lens.
[0011] It is a related object of this invention to provide an
automatic device that is small and compact, yet can receive and
clean virtually all available eyewear.
[0012] It is a related object of this invention to provide a
specially formulated solution for use in conjunction with the
automatic device that is safe to materials and coatings used in
eyewear that would dissolve dirt and grime on the eyewear and leave
a chemical coat that fills in micro-scratches on the lens.
[0013] A further object is to have this chemical coat be
anti-static to act as a repellent to dust particles.
[0014] A related object is to have the solution make the eyewear
feel cool and refreshing to the wearer when they are put on after
cleaning.
[0015] Another related object is for the solution to counteract the
effects of corrosion caused by sweat.
[0016] It is another object of this invention to provide an
automatic device that can effectively clean eyewear in the
specially formulated solution and then substantially dry the
eyewear, in sixty seconds or less.
[0017] It is a further object of the invention to provide an
automatic device that is easy to operate and to maintain.
[0018] A related object of the invention to provide a device that
is economical to operate, even with frequent use.
[0019] Another object of the invention is to provide a pleasing
display of lights while the eyeglass is being cleaned.
[0020] The above and related objects are addressed by embodiments
of the instant invention. In the following discussion, the terms
eyeglasses, eyewear, glasses will have the same meaning, and refer
to a common configuration comprising a frame, lens, nose rests,
hinges, and ear pieces.

DETAILED DESCRIPTION OF THE INVENTION
[0029] An automatic eyeglass cleaner is provided in accordance with
an embodiment of the invention. A specially formulated cleaning and
conditioning solution is also provided for use with the automatic
cleaner. A tank in the automatic cleaner is filled with the
cleaning and conditioning solution; the eyewear is folded up and
clipped to the bottom of the open lid of the cleaner, then the lid
is closed to lower the eyewear into the solution. The cleaning
cycle starts with the push of a button and the eyewear is agitated
in the solution. The cleaning cycle stops automatically after a
pre-set time, the lid pops up and any excess solution is shaken off
the eyewear by the cleaner leaving a thin film on the lenses. A
microfiber cloth is used to polish the lenses a quick final
touch-up that helps fill in microscopic scratches. The whole
process from start to finish should take only about one minute.
[0030] In FIG. 1, the exterior of an automatic eyewear cleaner
("cleaner") 10 is shown. In the illustrated embodiment, the cleaner
10 has a generally oval configuration. However, any configuration,
which is pleasing in appearance, would be suitable. The cleaner has
a lid 11 which pivotally opens upwards. The lid 11 covers the
removable solution tank 13 into which the cleaning and conditioning
solution is filled. In the embodiment shown, the tank fits in the
general profile of the cleaner when installed. The tank is made to
be removable from the cleaner for easy cleaning and disposal of
spent cleaning solution. The housing of the cleaner 14 houses the
electronics and motor, and has operating controls 15. The controls
shown, in the form of buttons 15a and 15b, opens the lid, and turns
the cleaner on and off.
[0031] FIG. 2 shows the cleaner, from a different angle, with its
lid 11 open and showing the removable tank 13 underneath. The tank
slides out in the direction of arrow 21. A small storage
compartment 13a can be made integral with the tank. An exemplary
pair of eyeglasses 23 is shown in this diagram. A removable holder
clip 24 for clipping the eyeglasses 23 is removeably attached to a
receptacle 25 on an agitator arm 26. The lid, shown here in its
open configuration, should become (and remain) fully open at an
angle sufficient for easy attachment and detachment of the clip and
eyeglasses, with the tank filled and attached to the cleaner. The
lid should remain open even with the full weight of the clip and
eyeglasses attached to it, until the user presses down on the lid
to close it. During the drying cycle, the lid opens, and raises the
glasses above the solution, until the user is ready to retrieve
them. The lid opening and closing mechanism and the agitator arm is
described further below.
[0032] Fill lines on the tank show a recommended minimum fill level
and maximum fill level the solution should be filled to. A minimum
level 28a is set so that the solution will cover the entire
eyeglasses when the lid is closed to lower the eyeglasses into the
solution tank. The maximum fill level 28b shows the maximum amount
of solution that should be filled, in order to avoid spillage and
splattering when the device is in operation and when the filled
solution tank is removed for disposal of spent solution. A cover 81
(see FIG. 8) can also be used to seal the tank so the solution
would not spill during transportation to and from a sink.
[0033] In FIG. 3a, a removable holding clip is shown in its closed
configuration. The clip is ordinarily held shut by a spring 30, and
opens when pressure is applied to the handles 31a, 31b. When in the
open position shown in FIG. 3b, the clip can receive a pair of
eyeglasses by positioning the clip over the nose bridge of a folded
pair of eyeglasses. When pressure is removed, the clips close and
hold the eyeglasses through retention means, such as rows of rubber
teeth shown as 32a and 32b. The clip has a finger grip area 34 on
the lower handle 31a to facilitate easy loading and unloading of
the clip into the cleaner without applying pressure to both
handles, which would open the clip and release the glasses.
[0034] In a preferred embodiment of the invention, a magnet and
metal combination is used to attach the clip (and the glasses held
by the clip) to the receptacle on the agitator arm to allow for
easy placement of the eyeglasses into the cleaner. A magnet or
metal piece 33a is made integral with an attachment part 33 on the
clip, with a corresponding magnet or metal piece on a receptacle
integral with the agitator arm. The clip will be magnetically drawn
to the receptacle when in proximity to it, and the shape of the
receptacle, which matches the attachment means on the clip, will
ensure a secure fit. The magnet should be of sufficient strength to
hold the clip loaded with eyeglasses throughout the cleaning and
drying cycles, until the user removes the clip by simply pulling on
it to disengage the magnet.
[0035] FIG. 4 shows a front view of the cleaner, with the solution
tank removed and the cleaner lid not shown. Slots 41 slidably
receive matching parts on the tank to ensure the tank is properly
seated when loaded into the cleaner. The clip 24 is shown
magnetically secured to the receptacle 25. The receptacle is
integral with the agitator arm 26, which extends into the cleaner
housing 14 and forms a motor housing 27 for the motor 28 (described
in detail below).
[0036] FIG. 5 shows a cut-away view of the cleaner housing from the
back. The arm is aligned but not connected to the cleaner lid, with
both being pivotally mounted along the same axis, 51. The arm is
designed to be separate from the lid so that when the lid is closed
and the agitator arm is vibrated to agitate the eyeglasses in
solution, the vibrations passing directly to the lid is minimized.
The cleaner, thus, remains relatively stable on a flat surface as
it is operated, because the vibrations from the agitation is kept
internal to the cleaner.
[0037] Refer now to FIG. 6, which shows in isolation the mechanical
parts of the cleaner, and FIG. 7, which shows a cross-section of
the unit. Direction arrow 60 in both diagrams designate the front
of the unit. The cleaner lid 11 is pivotally mounted at 62 on two
damper torsional springs 63, with the torsional springs secured
with screws 64 onto the cleaner housing along axis 51 (see FIG. 6).
The torsional springs exert tension to hold the lid in its open
position. A part of the lid aft of the axis 51 extends inside the
housing and forms a curved surface 11b, which slopes downwards. The
lid pivots around axis 51 as the lid is raised and lowered, and the
curved surface moves in opposite relationship with the front of the
lid. When the front of the lid is pushed down to close the lid, the
curved surface pivot upwards and its end clicks onto a
spring-loaded catch 70 and the lid is held closed (see FIG. 7). A
raised rubber divot 61a on the agitator arm, mounted forward of
axis 51, pushes down on the arm as the lid is closed and lowers the
clip and the eyeglasses (not shown) into the solution tank. Button
15a, which is depressed to open the lid, is integral with a
push-rod 15 which extends downwards to come in contact with the
catch. Depressing button 15a pushes down on the rod, which would
release the catch and allow curved surface 11c to pivot downwards
(from the tension exerted by the damper torsional springs 62), thus
raising the front of the lid. As the lid opens, it exerts pressure
on raised rubber divot 61b on the agitator arm positioned aft of
the axis 51, and raises the agitator arm to lift the eyewear out of
the solution. In order to eliminate splatter as the eyewear is
lifted, the damper torsional springs can be immersed in thick
viscosity lubrication so that when the lid opens, it does so
gradually.
[0038] As mentioned above, the agitator arm 26 extends into the
cleaner housing 14 and is integral with a motor housing 27, which
holds the motor 28. The motor housing and motor is positioned aft
of axis 51. Refer to FIG. 5, when the agitator arm pivots around
axis 51 as it is raised and lowered, the motor, being held by motor
housing 27, moves in opposite relationship to the front receptacle
end of the arm. Refer to FIG. 7, the motor, held by the motor
housing, remains integral with the agitator arm at all times,
whether the agitator arm is raised or lowered.
[0039] In a preferred embodiment, the motor is powered by common DC
batteries 71 which are inserted into the cleaner housing 14 through
a door on the bottom. Referring back to FIG. 5, the motor rotates a
shaft 54 which extends out of the sides of the motor, and onto
which weights 55 are eccentrically mounted on each side. When the
motor is turned on, strong, rhythmic vibrations are produced by the
weights rotating off-center at high speed. The vibrations are
directly transferred through the motor housing and onto the
agitator arm, including the front receptacle. When the clip and
eyeglasses are loaded onto the receptacle, they are vibrated as
well. In a preferred embodiment, the motor should operate at about
1300 rpm, which is well below ultrasonic range, but still
sufficient to produce strong agitation when the eyeglasses are in
the cleaning solution, and sufficient to substantially shake dry
the eyeglasses when they are raised from the solution. In a
preferred embodiment of the invention, during the cleaning and
drying cycles just described, the motor continues to operate
uninterrupted at the same speed, with the difference being whether
the front of the agitator arm is lowered or raised.
[0040] Once the lid is closed to lower the eyeglasses into the
solution tank, the user depresses button 15a to begin the automatic
cleaning procedure. Referring back to FIG. 6, button 15a depresses
an electrical contact 67 to activate electronic timing circuitry
67, turning on the motor. In an alternative embodiment, a
mechanical or electromechanical timer can also be used. During the
cleaning cycle, the motor operates for a preset amount of time and
agitates the glasses in the solution. In a preferred embodiment,
the cleaning cycles lasts about 40-50 seconds, which is sufficient
time for the cleaning and condition solution to substantially
dissolve and/or remove the dirt and grime from the frame and lens.
At the expiration of this amount of time, the timing circuit begins
the drying cycle and triggers an electromagnet 81 located in the
housing, which attracts a metal piece 70a integral with the
releasable catch 70. This pulls the catch backwards towards the
electromagnet and releases the curved end 11b of the lid, and the
front of the lid is raised due to the tension exerted by the
torsion springs. As discussed previously, the agitator arm (and the
clip with eyeglasses attached to it) is raised out of the solution
by the opening lid. The lid pivots around axis 51 until the front
of the lid is stopped by edge 14a, with the lid remaining in its
fully open configuration and the glasses held above the solution
tank. The agitator arm continues to vibrate in this raised
position, and the wet eyeglass is shaken substantially dry.
Solution dripping from the eyeglasses is collected by the solution
tank and can be re-used in future cleanings. In a preferred
embodiment, the drying cycle lasts about 10-20 seconds, after which
the timing circuit turns the motor off. Note that from the
beginning of the cleaning cycle to the end of the drying cycle, the
motor remains running uninterrupted.
[0041] In another embodiment of the invention, the electronic
timing circuitry can also control the timing of LCD or LED lights
45 (see FIG. 4) positioned in the housing behind the solution tank
and shine through the solution to create a pleasing lightshow. In
this embodiment, the cleaner should be made of a transparent or
translucent material for the light to shine through.
[0042] In a preferred embodiment, the novel cleaning and
conditioning solution for use with the automatic eyeglass cleaner
described above is comprised of deionized water, Berol 226,
Triethanolamine 99, Hydroxymethylglycinate, Isopropyl Alcohol,
Sorbitan Mono-oleate, acid blue 9 and Polydimethylsiloxane
Emulsion. See Table 1 for the percentage by weight of each
ingredient in a preferred embodiment.

[0043] Berol SA is a blend of a nonionic and cationic surfactant
optimized for use in water based degreasing cleaners. It is
efficient for cleaning organic soils, such as grease and oil.
Triethanolamine 99% is formed from the reaction of ethylene oxide
and ammonia. It is miscible with water and alcohol and makes the
solution alkaline, and improved grease removal and the
compatibility of the ingredients. A biocide, the aqueous solution
of Sodium Hydroxymethylglycinate is derived from Glycine--a
naturally occurring amino acid. It has broad spectrum antimicrobial
activity and is effective against bacteria and fungi. Isopropyl
Alcohol, also known as IPA, 2-propanol and isopropanol, is a
colorless clear liquid with a pleasant odor. It is a good
dehydrating agent and disinfectant. Sorbitan Mono-oleate is a light
amber-color surfactant that is used as an nonionic lipophilic
surface active agent. It is an emulsion stabilizer. The aqueous
emulsion of polydimethylsiloxane is an anti-fogging agent and gives
the eyewear a slick feel. It is a relatively inert, and is easy to
dilute and disperse and is effective over a wide range of
temperature and pH conditions. Acid Blue 9, also known as Brilliant
Blue FCF, C.I. Acid Blue 9, diammonium salt, C.I. Acid Blue 9, and
disodium salt, is a widely used food dye. It comes in a
reddish-violet powder or granules with metallic luster.
[0044] The solution is manufactured by adding the above ingredients
in the following order: deionized water, Berol 226, Triethanolamine
99, Hydroxymethylglycinate, Isopropyl Alcohol, Sorbitan
Mono-oleate. The mixture is mixed until all the ingredients are
dissolved and uniform. Next, 1% Acid Blue 9 is added to the
solution and mixed. Polydimethylsiloxane emulsion is then added
while the solution continues to be mixed, and the solution should
be mixed for at least another fifteen (15) minutes to obtain the
final solution in concentrate form having a pH of 9.2-10.2 and a
specific gravity of 1.018-1.024 (gm/ml). The concentrate is to be
diluted approximately 1:32 with ordinary tap water to obtain a
cleaning solution for use in the cleaner.
[0045] The cleaning solution has the properties of being able to
emulsify and dissolve body oils, dirt and grime deposited on the
frame and lens. Further, the solution will form a thin film on
surfaces it comes into contact with, especially the lens of the
eyeglasses. This film can fill in micro-cracks and scratches on the
surface of the lens and coating, and helps in restoring the surface
of the lens.
[0046] After the drying cycle is complete, the frame and lens of
the glasses should be substantially dry, with the thin film of
silicone deposited on the lens. The user reaches into the open lid,
and grabs the clip with his fingers. A simple pull will disengage
the magnet holding the clip to the receptacle on the agitator arm,
and the loaded clip is removed from the cleaner. The handles of the
clip are depressed to release the eyeglasses. Finally, a
micro-fiber cloth is used to briefly polish and dry the lens, a
quick final touch-up that helps the silicon fill in microscopic
scratches. The sparkling-clean glasses are now ready to wear.
[0047] It will be appreciated that the instant specification,
