Abstract:
The self-cleaning eyeglasses are an invention that provides an efficient and convenient means for cleaning the surface of lenses without removing the eyeglasses from the face of the wearer. In order to accomplish this the present invention includes a novel design for a housing shaped to seat a watch battery and formed within the frame of the eyeglasses. Also introduced by the present invention is a dual motor design wherein each motor is housed in the frames of the eyeglasses above the lenses of the eyeglasses. The motors rotate a shaft over a fixed acute angle. Attached to the shafts of the motors are wiper arms held flush to the surface of the lenses. Also housed within the frames is an On\Off switch. When the switch is activated the watch battery will supply current to the motors which will drive the shaft to sweep the wiper arms over the lenses.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an improvement in eyeglasses that enables the wearer to remove moisture or other detritus from the surface of lenses without removing said eyeglasses. The mechanisms employed by the present invention will accomplish this in a cost effective and efficient manner. 
     2. Description of the Prior Art 
     One of the greatest inconveniences related to the use of eyeglasses is the need for regular cleaning to maintain adequate vision. Most wearers will have to remove and clean their glasses several times a day. This is normally done with a cloth specially designed for cleaning lenses or by using one of several cleaning fluids on the market. This can be very inconvenient since the wearer has to carry one of these items with them. In addition, when weather conditions are poor, eyeglasses may need wiping so often that it would be impractical. For example, when it is raining the lenses will constantly be exposed to water and no amount of wiping by hand will afford the wearer clear vision for sustained time. This can render people with poor vision virtually helpless when exposed to such conditions. Thus a design that would incorporate a mechanism for cleaning lenses automatically while being worn would greatly improve the field of vision enhancing eyewear. 
     The most efficient mechanism for cleaning glass to maintain translucence is a wiper. Tins mechanism includes a malleable material such as rubber, mounted on an arm that is held so that the material is flush with the glass. The material is then swept across the surface of the glass removing any unwanted materials on the surface. While there are a variety of designs in the prior art, which attempt to make it possible for eyeglass wearers to use this mechanism, none of these designs are as efficient or convenient as the present invention. The present invention represents a novel design that will facilitate cost effective production. It will also allow the mechanism to be relatively inconspicuous. 
     U.S. Pat. No. 3,754,298 to Raymond Louis Menil is for a pair of glasses that incorporate wipers. The design for these glasses comprises a motor located at the center of the frames. This motor comprises a cam that drives a gear. As the gear rotates it shifts a top-mounting arm back and forth. There are wiper arms mounted at either end of the top-mounting arm, which sweep back and forth on a pivot as the mounting arm pushes them back and forth. The motor is wired to a battery that is stored at a location outside of the frames. This design requires a large cumbersome compartment located at the center of the glasses which would be highly unattractive. It is also awkward since the battery would have to be stored elsewhere. Furthermore the wipers mounted in the center of the lens will be highly visible. While this design may be appropriate for a novelty item, it would be highly impractical for everyday use. This design also incorporates several more moving parts then the present invention, which would increase risk of wear and tear as well as increase the cost of production. 
     The eyeglass wiper design in U.S. Pat. No. 4,342,128 to Thomas P. Doyle is for a wiper that is not attached to the eyeglasses at all. It is a squeegee-like wiper that is attached to a chain or thread and is worn by the user separate of the glasses. When the wearer wants to use the wiper to clean their glasses, they must grasp the wiper and manually swipe the wiper across the surface of the lenses. This is much more inconvenient then the internal wiper design of the present invention since the wearer would have to carry separate item. It also would not be practical if the wearer were involved in a task that required use of both hands. 
     U.S. Pat. No. 4,789,233 to Edna M. Arsenault is for a wiper mechanism that is entirely manually driven. The wearer grasps a knob located at the pivot point of the wiper so that the wearer can rotate the knob back and forth causing the wiper to sweep across the surface of the lenses. This once again would not be practical if the wearer needs to use both hands for other tasks. Furthermore this design would require noticeable knobs protruding in front of the glasses, which would be highly unattractive. 
     U.S. Pat. No. 5,755,524 is for a portable cleaning device that may be carried to clean eyeglasses. The inconvenience of having to carry an extra item is not alleviated by this device. While it employs wipers for its cleaning mechanism, these wipers are not incorporated in the design of eyeglasses. Nor are these wipers automated, requiring the manual movement of the wipers in the cleaning action of the device. 
     In U.S. Pat. No. 5,946,071 a pair of eyeglasses is disclosed that includes a mechanism for illumination. As with the present invention, the Feldman &#39;071 patent comprises a battery operated device. However, in the Feldman &#39;071 design the battery is stored on the arm of the eyeglasses rather then the lens frame. This design requires the wiring of the device to pass through the joint of the eyeglasses and will eventually lead to wear and tear on the wire. Also, the lighting mechanism does not incorporate a motor driven system as with the present invention. Nothing in the design of the Feldman &#39;072 patent will address the need for a cleaning mechanism; rather its sole purpose is to provide illumination. 
     U.S. Des. Pat. No. 421,040 to Joseph L. Berke is for a pair of glasses that incorporates arms that pivot from the center of the glasses and mount mirrors. The mirrors may be situated so that the wearer may see behind him while looking forward. The Berke &#39;040 design does disclose a pair of eyeglasses that incorporate a separate mechanism. This mechanism however is not designed for cleaning. Nor is this mechanism automated; rather the wearer must mechanically operate it. 
     Therefore a need exists for a novel and enhanced device for cleaning eyeglasses. Making this action automated would allow the wearer to maintain use of their hands in all conditions and eliminate the need for carrying extra items. In this respect, the eyewear with attached wiping apparatus according to the present invention substantially depart from the conventional concepts and designs of the prior art, and in doing so provide an apparatus primarily developed for the purpose of cleaning eyeglasses. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of devices for cleaning eyeglasses now present in the prior arts the present invention provides an improved combination of convenience and utility, and overcomes the abovementioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved design for eyewear with attached wiping apparatus which has all of the advantages of the prior art mentioned heretofore and many novel features that result in eyewear with attached wiping apparatus which are not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in combination thereof 
     In furtherance of this objective the eyewear with attached wiping apparatus comprise a power source. A connection from said power source to a motor mounted within said eyeglasses. An arm mounted at a right angle to the shaft of said motor is flush with the surface of the lens of said glasses. 
     The abovementioned power source may in addition be a battery, which may be stored in a compartment integral to said eyeglasses. Said compartment may in addition be located at the joint between the arms of said eyeglasses and the frame of said eyeglasses. 
     Said eyeglasses may in addition comprise a power switch intermediate to the connection between said motors and said battery so that the wearer may control the power access of the battery to the motor. 
     Another feature of the present invention is that said arms may be attached to said shaft of said motor at the outer corners of the frames of said eyeglasses.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings, and particularly to FIGS. 1-4, a preferred embodiment of the eyewear with attached wiping apparatus of the present invention is shown and generally designated by the reference numeral  10 . 
     In FIG. 1 is a lens frame  12  comprising a top beam  14 . Connected to the lower surface of said beam  14  is a first and a second curved member  16 , the ends of which are mounted to said beam  14 . Said beam  14  and said curved members  16  join to define openings  18 . Mounted within said opening are lenses  20 . Following the standard design for lens frames, the present invention comprises slits on the surface adjacent to said opening  18  so that said lenses  20  may be seated within said slits. The present invention further comprises a curved bar  22 , the ends of which are mounted between said curved members. When the self-cleaning glasses are worn said curved bar  22  rests on the wearer&#39;s nose preventing said eyeglasses  10  from sliding down. Attached to said lens frame  12  at the outer union of said curved members and said top beam is a cylindrical housing  24 . Mounted within said housing  24  is a wiper motor  26 . Said motor  26  may be one that comprises a shaft, said shaft being driven in a periodic rotational motion covering a fixed angle. An example of a motor that would produce this motion is the worm gear design of several single arm wiper motors on the market. Said cylindrical housing  24  is shaped to define a hole  28  on the front end of said housing. Said shaft passes through said hole  28  and protrudes on the face of the present invention Attached to said shaft is an arm  30  which may be made of plastic. Said arm  30  is held at a right angle to said shaft and adjacent to the top front surface of said lenses  20 . The angle of rotation of said shaft covers the angle required for said arm  30  to proceed from said top edge of said lenses  20  to traverse the entire surface of said lenses. In order to improve the cleaning action of said arm  30  various materials may be attached to said arm that will seal the gap between said arm and said lens  20  to prevent moisture from sliding through. Rubber or cloth would be examples of suitable material. Attached to the outer edge of said curved members are a first  32  and a second  34  eyeglass arm mount. Said mounts comprise a housing. Said mounts further comprise a pair of fingers  36 . Said fingers comprise a hole. The present invention also comprises a pair of eyeglass arms  38  of the standard design. This design comprises a curved member  40  at the end of said arms designed to rest on the wearer&#39;s ears. Attached to the other end of said arms  38  are three fingers  42 , which further comprise holes. When said arm fingers  42  and said mount fingers  36  are placed in an interlocking position, said holes in said fingers form a bore. The present invention further comprises an axle said axle passing through said bore. This design allows said eyeglass arms  38  to be rotated about said axle from a closed position to an open position for easy storage. The first of said arm mount housing  32  comprises a hole. Mounted within said housing is an On/Off switch  44 . Said button  44  is of the standard design allowing the wearer to control the flow of current in a simple DC current circuit. 
     In FIG. 2 the motion of said wiper arms  30  is illustrated. Said wiper arms  30  are attached to said motor shaft at a right angle. The resting position of said wiper arms  30  is at the top edge of said lenses  20 . Said motor shaft rotates over a fixed angle in a back and forth motion. Said fixed angle is of a magnitude so that said wiper arm  30  traverses the entire surface of said lens  20 , removing unwanted moisture or detritus from the surface of said lens. Said lens frame  12  comprises a pair of curved members  16  attached to said top beam  14  so as to define an opening  18  wherein said lenses  20  may be held. Said lens frame  12  comprises a slit adjacent to said opening  18  so that said lens  20  may be inserted into said slit and be held in place. Said lenses  20  may be prescription or tinted depending on the wearer&#39;s needs. Said motor shaft passes through a hole in said motor housing  24 . Said motor  26  is seated in said motor housing  24 . Said top beam is formed to comprise a passage  46 . Said passage  46  passes between said motor housings  24  and is connected to the interior compartment of said motor housings. Said curve members  16  are also formed to define a passage  48  passing from said motor housings  24  to the interior cavities of said arm mounts  32  and  34 . Housed in said first arm mount  32  is an On\Off switch  44  comprising an On\Off button passing through said hole in said first arm mount  32 . Housed in said second arm mount  34  is a disk shaped battery  50  of the typical watch battery design. Said housing  34  comprises a detachable cover  52  attached by a snap-on design. The present invention further comprises a first wire  54  attached to said On\Off switch  44  and attached to said motor  26  in said first motor mount  24 . A second wire  56  is attached to said motor  26  in said first motor mount  24  and said motor  26  in said second motor mount  24 . A third wire  58  is attached to said motor  26  in said second motor mount housing  24  and said battery in said second arm mount housing  34 . A fourth wire  60  is attached to said battery  50  and said second motor  26 . A fifth wire  62  is attached to said second motor  26  and said first motor  26  in said first motor housing  24 . A sixth wire  64  is attached to said first motor  26  and said On\Off switch  44 . The result is a complete circuit when said On\Off switch  44  is activated allowing said battery  50  to supply current to said first and second motors  26 . When the wearer wishes to clean her glasses  10 , she presses said button to close said circuit and supply current to said motors  26 . When the wearer wishes to stop said cleaning action, said button is again pressed to break said circuit. 
     The sectional view of FIG. 3 is a side view of the eyewear with attached wiping apparatus  10 . Said eyeglasses comprise a pair of arms  38 . Said arms comprises three fingers  42  that are formed too define a hole. Said arm fingers are interlocked with a pair of fingers  36  attached to said arm mount  32  and  34 . Said arm mount fingers  36  are formed to define a hole. Said holes are aligned to create a bore, which receives said axle and creates a hinge. Said arms  38  may be folded about said hinge to collapse said eyeglasses during storage. Said first arm mount  32  comprises a housing. Seated within said housing is an On\Off switch  44 . Said first arm mount  32  is shaped to define a hole accessing said housing. Said button for said On\Off switch  44  passes through said hole so that the wearer may press it to activate the cleaning process. Said first wire  54  and said sixth wire  64  pass from said On\Off switch  44  to said first motor  26 , supplying current. Said wires pass through said passage  48  formed in said curved members  16  between said arm mount housing  32  to said first motor housing  24 . Attached to said shaft of said first motor is a wiper arm  30  at a right angle. Said wiper is held flush with the surface of said lens  20  and is swept across the surface of said lens by said motor  26 . 
     The side perspective view in FIG. 4 illustrates an exploded view of the elements of said second arm mount housing  34 . The present invention comprises a second arm mount  34  attached to one of said curved members  16 . Said second arm mount  34  comprises a pair of fingers  36  and is formed to define a chamber  66  and an opening  68 . A standard disc shaped watch battery  50  is seated in said second arm mount  34  and a housing cover  70  is removably attached to said second arm mount  34 . The wearer may remove said cover  70  and insert said battery  50 . Said cover  70  is then replaced and holds said battery  50  in place. Said curved member  6  and said arm mount  34 are formed to define holes connecting said chamber of said housing to said passage  48  of said curved member. Seated in said hole is a connector  72 . Said connector  72  is attached to said third and fourth wires. When said On\Off switch  44  is pressed to activate the cleaning process said battery  50  supplies current to said wires which in turn relays said current to said first and second motors  26 . The present invention further comprises a pair of arms  38 . Said arms  38  comprise three fingers  42  which are interlocked with said pair of fingers  36  and hinged to allow the device to be folded for storage. 
     While a preferred embodiment of the eyewear with attached wiping apparatus  10  has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. 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. For example, any suitable rigid material may be used instead of the plastics that have been described. And although the design for eyeglasses has been described, there are slight variations, such as shape and size that would make the invention appropriate for other eyewear such as goggles. 
     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.
