## Background
The present invention relates to lens polishers and more particularly pertains to contact lens treatment apparatuses which may be utilized for polishing and cleaning a pair of contact lenses.

2. Description of the Prior Art

The use of lens polishers is known in the prior art. More specifically, lens polishers heretofore devised and utilized for the purpose of polishing lenses are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

For example, a manually operable contact lens surface treatment apparatus is illustrated in U.S. Pat. No. 5,023,971 which may be utilized for performing such contact lens surface treatment procedures as polishing, cleaning, or lens modification.

A polishing solution recirculating system for use with a contact lens polishing machine may be seen in U.S. Pat. No. 3,782,042 wherein lenses held by separate holders are brought into contact with a wetted surface polishing element disposed on a rotating spindle.

Another patent of interest is U.S. Pat. No. 4,979,337 which discloses a polishing tool for contact lenses that comprises a base, and exteriorly convex resilient polishing head, and a polishing cloth that may be utilized by connecting it to a rotatable shaft and exposing the polishing tool to the interior of a contact lens.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a contact lens treatment apparatus in which an electric motor rotates a pair of polishing probes each of which includes a solution measuring and dispensing system that is integrally formed therein.

In this respect, the contact lens treatment apparatus according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of polishing and cleaning a pair of contact lenses.

In view of the foregoing disadvantages inherent in the known types of lens polishers now present in the prior art, the present invention provides a new contact lens treatment apparatus construction wherein the same can be utilized for polishing and cleaning a pair of contact lenses. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new contact lens treatment apparatus which has many of the advantages of the lens polishers mentioned heretofore and many novel features that result in a contact lens treatment apparatus which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art lens polishers, either alone or in any combination thereof.

To attain this, the present invention essentially comprises a contact lens treatment apparatus for polishing and cleaning a pair of contact lenses. The apparatus utilizes a pair of polishing probes to clean each contact lens within a liquid bath. A motor rotates the polishing probes and a fluid reservoir supplies a solution to the lenses. The polishing probes include a cleaning solution measuring and dispensing system integrally formed therein.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

With reference now to the drawings, and in particular to FIGS. 1-4 thereof, a new contact lens treatment apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, it will be noted that the contact lens treatment apparatus 10 comprises a body assembly 12 that includes a plurality of compartments which are integrally connected together. A motor compartment 14, a gear compartment 16, and a fluid compartment 18 are all integrally or otherwise connected together to form the body assembly 12 as shown in FIG. 1. In addition, a pair of lens containers 20, 22 are also integrally connected to the body assembly 12 and are closed by a pair of caps 28, 30 which, along with the lens containers 20, 22, may be constructed of any material, including transparent materials which allow a user to view an interior of the lens containers. A pair of probe shafts 24, 26 pass through apertures in both the gear compartment 16 and the pair of caps 28, 30. Each of the pair of probe shafts 24, 26 has a knob 32, 34 located at a first end and a probe 36, 38 at a second end of each respective probe shaft. Each of the probes 36, 38 is substantially hemispherically shaped and is comprised of any material which may be utilized for cleaning and polishing contact lenses such as cloth, foam materials, and the like The caps 28, 30 have threads located on an interior surface of each of the caps and may be threadably engaged to respective lens containers 20, 22 in a well understood manner. Each probe shaft 24, 26 further supports a coil spring 40, 42 thereon which are operable to bias each of the probes 36, 38 towards the lens containers 20, 22, respectively.

Located within the motor compartment 14 is an electric motor 44 that is mounted in a conventional manner with a motor shaft 46 projecting into the gear compartment 16. Also located within the motor compartment 14 in a juxtaposed relationship to the motor 44 is a plurality of batteries of conventional design which are operable to supply electrical power to the motor through a plurality of contacts 49. Adjacent the batteries 48 is a switch 50 which is electrically connected to the motor so that a user may operate the switch to interrupt a flow of electrical power to the motor in a well understood manner. The switch 50 is mounted to an interior wall of the motor compartment 14 in such a manner so as to allow a portion of the switch to project through an aperture (not labeled) in the motor compartment 14.

A motor gear 52 is fixedly secured to the motor shaft 46 in such a manner so as to provide a rotation of the motor gear upon a rotation of the motor shaft. The motor gear 52 is operable to engage a pair of shaft gears 54, 56 within the gear compartment 16. Each shaft gear 54, 56 contains a plurality of spline receiving journals located on an interior of the center axis. The spline receiving journals are operable to receive and engage the splines 57 that are present on each of the probe shafts 24, 26 as illustrated in FIG. 2. This arrangement allows a rotatable coupling between each of the shaft gears 54, 56 and the probe shafts 24, 26, respectively, while still allowing a sliding movement of the probe shafts.

The fluid compartment 18 includes a reservoir 58 for containing a cleaning fluid 60 therein and may also contain an unillustrated window through which a user may view a level of such cleaning fluid. The reservoir 58 is in fluid communication with both of the lens containers 20, 22, whereby the cleaning fluid 60 may travel through a channel 62 and into the lens containers. The fluid compartment 18 further comprises a hole 64 that allows for an addition of the cleaning fluid 60 or other cleaning product, such as an enzyme tablet and water, into the reservoir 58. A plug 66 may be removably secured within the hole 64 to contain the cleaning fluid 60 therein.

The contact lens treatment apparatus 10 may be utilized by placing each of a pair of contact lenses within each of the lens containers 20, 22. The contact lenses, when placed within the lens containers 20, 22 will reside upon respective lens rests 68, 70 within each of the lens containers, as best shown in FIGS. 3-4. The caps 28, 30 can then be used to seal their respective lens containers 20, 22 so as to prevent an escape of the cleaning fluid 60 therefrom. The reservoir 58 may then be filled with cleaning fluid 60 through the hole 64 in the fluid compartment 18. The motor may then be energized by an actuation of the switch 50 by a user. Upon an energization of the motor 44, the probe shafts 24, 26 will rotate their respective probes 36, 38 which will polish the lenses placed between the probes and the lens rests 68, 70. An unillustrated timer, also in electrical communication with the motor 44, may be selectively operated in a well understood manner to de-energize the motor after a predetermined amount of time has elapsed. Each contact lens may then be removed from the invention 10 by a use of a user's fingers, or alternatively, a contact lens applicator of conventional design may be utilized.

A second embodiment of the present invention which comprises substantially all of the features of the foregoing embodiment 10, and which is generally designated by the reference numeral 72, can be seen in FIGS. 5-6. The second embodiment 72 further comprises a pair of drains 74, 76 that are located on respective caps 28, 30 of the lens containers 20, 22. The drains 74, 76 are operable to allow cleaning fluid 60 to be expelled from each of the lens containers 20, 22, respectively. A drain tube 78 may be inserted into the drains 74, 76 to direct an exit of cleaning fluid 60 therefrom. The drains 74, 76 may be releasably sealed by a pair of closures 80, 82 located on the respective caps 28, 30, as illustrated in FIG. 5.

The drains 74, 76 are useful to allow a user to rinse the contact lenses within the lens containers 20, 22 without touching the lenses. An additional reservoir 84 is equipped with a nozzle 86 that allows fluid 60 contained within the additional reservoir to replenish any of the fluid in the reservoir 58 that may exit through the drains 74, 76.

Comprising all of the features and structure of the previous embodiments 10, 72 is a third embodiment which is generally designated by the reference numeral 90 and may be viewed in FIGS. 7-8. It can be shown that the third embodiment 90 further comprises a dispensing probe 92 which is substantially hemispherical shaped and which includes a plurality of dispensing holes 94 located proximate a perimeter edge 93 of the dispensing probe. The dispensing probe 92 further includes a probe cover 95 which covers and frictionally engages an open area of the dispensing probe 92. A solution 96 may be placed within the dispensing probe 92 and contained therein by the probe cover 94. Upon a rotation of the probe shaft 24, the solution 96 may be biased by centrifugal forces through the dispensing holes 94, thus applying the solution to a contact lens located therebeneath.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
