Description

FIELD OF THE INVENTION

This invention relates to an optics cleaning apparatus and method. In particular, in accordance with one embodiment, the invention relates, to an optics cleaning apparatus including a holder with a first end, a second end and an outer surface where the outer surface encloses an internal reservoir. A fluid applicator is connected with the first end and with the internal reservoir and a scrub pad is connected with the second end.

BACKGROUND OF THE INVENTION

A problem arises with regard to devices that include lenses. Devices such as safety glasses, eyeglasses, cameras, binoculars, rifle scopes, microscopes, telescopes, video lenses, computer and analog monitors, personal digital assistants (PDAs) and the like have lenses that must be kept clean in order to function at full capacity. Dirt, moisture, smears and or fogging, smudges, oil, and other debris present in the working environment of the device are a constant source of contamination and create an ongoing need for constant cleaning of the lens.
Prior art solutions range form using anything handy, shirt sleeves, tissue paper and such, to dedicated cleaning solutions and cloths. The problem with the prior art solutions are that the handy items may seriously compromise the lens, scratching or damaging it beyond usefulness. As the expense of the device increases the need for a proper, non-damaging solution to the problem increases such that users find themselves having to have a shelf load of cleaning supplies available when needed. Supplies required for a proper cleaning include a wide variety of devices and materials such as large particle dirt removers such as brushes and wipes. Also required are cleaning solutions, cleaning solution applicators and scrubbers, and cleaning and drying cloths that do not damage the lens. Such an assortment of materials is cumbersome and difficult to transport easily “in the field”, in particular, and as a result, lens care often reverts to what is handy. What is handy, though, risks seriously degrading the lens.
Thus, it is clear that a need exists for a fully self contained, optics maintenance apparatus and method for cleaning optics that enables a professional cleaning of a lens “in the field”, that is safe and easy to use and that is not cumbersome to carry or hard to maintain.
It, therefore, is an object of this invention to provide an apparatus and method for cleaning optics that is not cumbersome to carry, that is easy to maintain, that is safe and easy to use and that enables a professional lens cleaning wherever and whenever needed.

DETAILED DESCRIPTION OF THE INVENTION

The preferred embodiment of the present invention is illustrated by way of example in FIGS. 1-6. With specific reference to FIG. 1, an optics cleaning apparatus 10, according to one embodiment, includes a holder 12 with a first end 14 and a second end 16. Holder 12 may be any desired shape but is preferably tube like with a round outer surface 18 for example only and not by way of limitation. Holder 12 includes a hollow space created by outer surface 18. The hollow space on the inside of holder 12 serves as a reservoir 20 as more clearly shown in FIG. 5.
Holder 12 may be made of any desired material such as plastic or metal. Holder 12 may be in any dimension such as one-half inch to one inch in diameter and three to six inches in length, for example only. The point to be noted is that it is very compact and thus it is easy to store and transport. It will fit, for example, in a shirt pocket.
Fluid applicator 22 is connected with first end 14 of holder 12 and with reservoir 20. Thus, fluid applicator 22 is of sufficient length such that there is an exterior portion 24 and an interior portion 26 of fluid applicator 22 as more clearly shown in FIG. 5.
Fluid applicator 22 preferably may be made of any porous material now known or hereafter developed that absorbs and releases fluid. MAKA MARK™ by Chuck Moore of Elkton, Tenn. and SHARPIE™ Marker Pens are suitable and representative of the type and function of the applicator required by the invention. Fluid applicator 22, it should be understood, acts as a wick to transport fluid from the reservoir 20 to the exterior portion 24 of fluid applicator 22 as will be discussed more fully hereafter. It should be understood, however, that fluid applicator 22 may be a spray nozzle, as known in the art and not described more fully hereafter, connected with the reservoir 20 and still serve the required purpose of the invention.
Scrub pad 28 is connected with second end 16 of holder 12. Scrub pad 28 is made of any suitable material such as a micro fiber material such that use of the scrub pad in evenly spreading a fluid 30 onto a lens (not shown) and rubbing and scrubbing the lens does not scratch or damage the lens or any lens coatings that may be present. Any such material now know or hereafter developed is suitable.
Preferably, a fluid applicator cover 32 and a scrub pad cover 34 are provided as well. The covers ensure that dirt and debris are prevented from coming in contact with fluid applicator 22 and scrub pad 28 when they are not in use. Further, the covers connect with holder 12 to form a single sealed unit as shown in FIG. 3. This prevents the escape of fluid 30 when not in use, for example, and keeps the scrub pad 28 clean. Covers 32 and 34 may be press fit connected or screw thread connected with holder 12 or connected in any other effective manner.
Referring now to FIG. 2, buffing cloth 36 is illustrated. Buffing cloth 36 is preferably made of a micro fiber material that is absorbent and soft such that it will not damage lenses or lens coatings. Preferably buffing cloth 36 is of a size to fit within one of the covers 32 or 34. Applicant has found that extending scrub pad cover 34 a little provides space to include buffing cloth 36. Location in fluid applicator cover 32 is possible as well but it was found that the buffing cloth 36 would absorb fluid 30 from fluid applicator 22 and is not ideal.
In one aspect, Applicant has determined that adding a buffing cloth removal device 38 is very useful. Buffing cloth removal device 38 preferably is in the form of an extension or “rat tail” from the buffing cloth 36. In use, the buffing cloth 36 is stuffed into the end cap 34 with the removal device 38 pushed in last. When time comes to remove the buffing cloth 36 the user simply pulls on removal device 38 and the buffing cloth 36 is easily retrieved for use.
Referring now to FIG. 4 an exploded version of another embodiment of the optics cleaning apparatus 10 is illustrated in which like numbers are used to identify like parts as described above with regard to FIGS. 1 and 3.
Accordingly, optics cleaning apparatus 10 includes a holder 12, with a first end 14 and a second end 16 and an outer surface 18 enclosing a reservoir 20 (see FIG. 5). A fluid applicator 22 is provided that includes an exterior portion 24 and an interior portion 26. The interior portion 26 extends into reservoir 20, all as described above.
Further, however, in this embodiment, as shown in FIG. 5, reservoir 20 includes an absorbent cartridge 40. Fluid 30, such as lens cleaning and anti-fogging fluid as is known in the art, is introduced into reservoir 20 where it is absorbed by absorbent cartridge 40 and then slowly released or transferred to the interior portion 26 of fluid applicator 22. In use, the exterior portion 24 of fluid applicator 22 transfers fluid 30 to a lens as described above. A suitable cleaning and defogging fluid 30 is PARKER'S PERFECT™ by ParBur Labs of Hollister, Mo., for example only and not by way of limitation.
Absorbent cartridge 40 facilitates the uniform transfer of fluid 30 and continuously absorbs fluid 30 from reservoir 20. Importantly, according to this embodiment, second end 16 is removable such that fluid 30 may be added to reservoir 20 as needed. In the embodiment shown in FIG. 1, this means that scrub pad 28 is unscrewed or disconnected from second end 16 which exposes fluid reservoir 20 and allows fluid 30 to be added. After filling, the scrub pad 28 is reconnected with second end 16 and the optics cleaning device 10 is ready for continued use.
According to the embodiment shown in FIG. 4, a dust brush 42 is connected with second end 16 and the scrub pad 28 is connected to the holder 12 by connection with the dust brush 42 as shown. Dust brush 42 is a non-abrasive anti-static brush useful when needed to remove large dust and debris prior to application of cleaning fluid 30. A suitable brush is made by Gordon Brush Mfg. Co. of Commerce, Calif. that is made of goat hair, for example only and not by way of limitation.
Still referring to FIG. 4, this embodiment is a more rugged embodiment in that fluid applicator cover 32 and scrub pad cover 34 are connected with holder 12 by threaded engagements 44 as illustrated. Further, gaskets 46 are provided to ensure a closed and sealed environment when attached.
Likewise, dust brush 42 is connected with second end 16 with threaded engagements 44 in combination with gasket 46 to ensure that fluid 30 is prevented from leaking out of reservoir 20. Similarly, scrub pad 28, in this embodiment, is connected with holder 12 by connection with dust brush 42 by threaded engagements 44 and including sealing gasket 46 as illustrated.
Referring to FIG. 5, a partial section view of the invention of FIG. 3 is presented that illustrates the connection of the fluid applicator 22 with an absorbent cartridge 40 within the reservoir 20. Here, fluid 30 in the reservoir 20 is absorbed by absorbent cartridge 40 and, passes to interior portion 26 and then to exterior portion 24 of fluid applicator 22 as described above. It should be understood, of course, that absorbent cartridge 40 and fluid applicator 22 may be a single piece of material that is both absorbent and strong enough to serve as an applicator.
Referring to FIG. 6, the optics cleaning apparatus 10 is shown assembled with covers 32 and 34 in place. As assembled, optics cleaning apparatus 10 is a fully self contained optics cleaning kit that is easy to use and easy to carry. In this configuration, including the dust brush 42 attachment, the Applicant has determined that a functional device includes the dimensions of three-quarters of an inch to one and one-half inches in diameter and five to ten inches in length. Again, any suitable dimensions for the task that are functional are acceptable. Further, it should be understood that some or all of the listed elements of the invention are removable and replaceable. On the other hand, a simple version of the invention as shown, for example, in FIG. 1 may be designed to be used and thrown away.
In operation, a user carries optics cleaning apparatus 10 with him, in his shirt pocket, for example. When a lens on a device being used needs cleaning, the optics cleaning apparatus 10 is pulled out. First, in the version shown in FIG. 1, fluid applicator cover 32 is removed and fluid applicator 22 is used to apply fluid 30 to the lens. Fluid applicator cover 32 is replaced and scrub pad cover 34 is removed and scrub pad 28 is used to evenly distribute fluid 30 on the lens and to clean the lens with the fluid 30. Then, if present, buffing cloth 36 is removed with buffing cloth removal device 38 from scrub pad cover 34 and used to buff and dry the lens. Then the buffing cloth is stuffed into scrub pad cover 34 with the buffing cloth removal device 38 last and the cover is replaced. Optics cleaning apparatus 10 is now ready for reuse.
In the case where a user carries optics cleaning apparatus 10 in the version shown in FIG. 4, before applying the fluid 30, scrub pad cover 34 along with scrub pad 28 are unscrewed from holder 12. Dust brush 42 is then used to brush dust and debris from the lens. Then fluid 30 is applied. Scrub pad 28 is reconnected and used as described above. Then scrub pad cover 34 is reattached and the optics cleaning apparatus 10 is ready for use again.
Should fluid 30 run low, this version enables the user to add more fluid by removing dust brush 42 from the second end 16 of holder 12. This exposes reservoir 20 and, in this case absorbent cartridge 40. Fluid 30 is added, the apparatus reassembled and it is ready to go.
The description of the present embodiments of the invention has been presented for purposes of illustration, but is not intended to be exhaustive or to limit the invention to the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. As such, while the present invention has been disclosed in connection with an embodiment thereof, it should be understood that other embodiments may fall within the spirit and scope of the invention as defined by the following claims.
