## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention, in general relates to pediatrics and, more particularly, to a device for use in a shower that is adapted for cleaning and abrading the skin on a foot.
The foot is a neglected portion for most people. It is generally difficult to clean when a person is in the shower. The person has to stand on one leg, which is dangerous, while cleaning the opposite foot or the person is required to bend down while standing under the shower. Many people lack flexibility to bend down and reach their feet. Consequently, people often omit washing their feet or if they do, they perform only a cursory cleansing.
These problems are especially difficult for people who suffer from disorders such as obesity, back problems, or other handicaps.
The foot is also prone to many dermatologic problems as well. People develop athlete's foot (one of many possible fungal infections), corns, calluses, and the like. Many people neglect treating these disorders for similar reasons as mentioned above.
People who suffer from athlete's foot know how severely their feet can itch. Minor abrasion of the affected area can alleviate itching while helping to remove layers of dead skin and promote the efficacy of certain athlete's foot medications that are topically applied. People with calluses on their feet know how difficult it is to bend down and use a hand held tool to abrade away their calluses.
Psoriasis and eczema sufferers also similarly benefit from abrading some of the dead skin off of the affected areas before applying any medication to the area.
It is also desirable to be able to massage a foot. This is well known to relax and calm a person.
Accordingly, there exists today a need for an apparatus and method for cleaning the feet of a user during the normal course of taking a shower that helps ameliorate the aforementioned difficulties while abrading dead skin and massaging the foot.
Clearly, such an apparatus and method would be useful and desirable.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawing FIGURE is shown, a foot cleansing device and method, identified in general by the reference numeral 10.
A container 12 is placed on the floor 14 of a bathtub or shower stall where a person taking a shower would normally stand. The container 12 includes feet 16 that elevate a bottom of the container above the floor 14 sufficient to allow water coming from a shower 18 to drain through a plurality of openings 20 that are provided in the bottom of the container 12.
A fine first screen netting 22 is disposed on the bottom of the container 12. The first screen netting 22 is formed of any preferred mesh material, including nylon or galvanized screening material, cheese cloth, or any other desired material.
As shown in the FIGURE, the first screen netting 22 is elevated above the bottom. This is only for purpose of improving clarity as to the layers of components that are disposed within the container 12. The first screen netting 22 is preferably adhered directly to the bottom of the container 12 so that it covers all of the openings 20. The remaining components rest directly upon those that are underneath.
The first screen netting 22 prevents larger debris that may wash of a foot 24 of a user from passing through the openings 20 in the bottom of the container 12 and possibly clogging a drain (not shown). It also prevents any of a variety of abrasive materials 26 that may migrate to the bottom of the container 12 from passing through the openings 20 and clogging the drain. The abrasive materials 26 are discussed in greater detail hereinafter.
A section of foam 28 is surrounded by a second screen netting 30. The second netting 30 is similar to the first netting 22, however it fully surrounds the foam 28. It is described in greater detail hereinafter.
The foam 28 and the second netting 30 are disposed on the bottom of the container 12 directly on top of the first screen netting 22. The foam 28 preferably includes a type of foam commonly referred to as “egg crate” foam and is oriented so the points of the foam 28 are disposed upward. The foam 28 provides compression that adapts the foot cleansing device and method 10 to match the shape and contour of the foot 24.
A lining 32 of artificial grass turf (as is commonly used as a carpeting material for exterior porches, decks, or stairs) is disposed over the foam 28 and up and over the sides and a surrounding lip 34 of the container 12. The lining 32 is secured the container by a series of cords 36 that pass through both the lining 32 and the sides of the container 12. Of course many other methods for attaching the lining 32 are anticipated, for example, VELCRO, or other types of fasteners may be used.
The abrasive materials 26 are placed on top of the lining 32. Any preferred material may be used for the abrasive materials 26 from fine sand to courser grades of sand to large and highly abrasive materials, for example, gravel's, including epoxy coated aquarium gravel.
The abrasive materials 26 may be changed as the foot 24 adapts as well. For example, a user may at first have a tender underside 24a of his foot 24. He or she may begin by using a fine grade of “play box” sand for a period of time. Then, as the foot 24 acclimates, a courser grade of sand may be used and the process repeated as often as desired. In this manner, the underside 24a of the foot 24 is trained to tolerate standing on coarser materials.
The abrasive materials 26 are also varied to suit the intended purpose of the foot cleansing device and method 10. For example, to simply automatically cleanse the foot 24, the finer grades of sand are typically used for the abrasive materials 26. Prior to taking the shower 18, a soap 38 is optionally poured into the container 12 on top of the abrasive materials 26.
The user stands in the container 12 and takes the shower 18 in a normal fashion, washing their body while shifting the position of each foot 24 slightly and also shifting their weight from foot 24 to foot 24 as they flex and move during the course of the shower 18, as is common.
The sand (as the abrasive material 26) works its way up between the toes of the foot 24, cleaning and finely abrading these oft neglected body parts. The foam 28 cooperates with the lining 32 during the shower 18. The foot 24 sinks into the foam 28 which stretches the lining 32 in various places.
The result is that the lining 32 forces some of the abrasive materials 26 into contact with a side 24b of the foot 24, thereby automatically cleaning both the underside 24a and the side 24b of the foot 24.
If the user desires, he or she may actually rub the underside 24a or the sides 24b or both of the foot 24 against the lining 32 on the sides of the container 12.
While other materials can be used for the lining 32, the artificial grass turf provides advantages in that it (along the sides of the container 12) also helps to cleanse and massage the foot 24 while retaining the bulk of the abrasive material 26 on top and in between the “blades” on top. This (the blades of artificial grass) prevent excessive shifting of the abrasive material 26 from occurring.
The lining 32 also permits the water from the shower 18 to pass through itself (the plane of the lining 32) and reach the lower level (bottom) of the container 12 where it drains out through the openings 20. In this manner, the lining 32 acts as an upper level screen that retains the overwhelming bulk of the abrasive materials 26 on top while allowing water to pass through. The soap 28 is similarly washed away during each shower 18 thereby leaving the foot cleansing device and method 10 clean and ready for the next usage.
The soap 38 can include bath oils or bath crystals, as desired. When the user is done with the shower 18, each foot 24 has been automatically cleaned without requiring any additional time. Also, there is no need for the user to raise one leg for cleaning of the foot 24 dangerously high while attempting to balance for a long period of time upon the other. Each foot 24 smells fresh, is clean, and has had some of the dead skin removed when the shower 18 is complete.
The process of taking the shower 18 while standing in the container 12 causes the lining 32 to stretch and relax as described hereinabove from normal weight shifting and normal slight movements of each foot 24 while the foam 28 compresses and expands periodically as well. During these changes, the abrasive materials 26 contact the foot 24 in different areas and at varying pressures.
The effect transcends that of a mere automatic washing of the foot 24 and provides an experience that includes a massaging of the foot 24. The essence of a foot massage is to provide varying pressures of contact to various areas of the foot 24, which the foot cleansing device and method 10 provides. Not only does the user benefit from a thorough cleansing of the foot 24, the user also receives a foot massage every time he or she takes the shower 18.
Removal of dead skin has also been accomplished which promotes healthy feet while possibly decreasing the chances of contracting an athlete's foot fungal infection. If such an infection already exists, the foot cleansing device and method 10 promotes healing and aids in the absorption and resultant efficacy of medications that can then be applied.
If desired, coarser or more abrasive substances can then be substituted for the abrasive materials 26 or they can be progressively added to the current abrasive materials 26, as desired. More abrasive substances are especially useful for use as the abrasive materials 26 in removing dead and scaling skin, such as occurs with psoriasis, eczema, and other similar disorders. There is virtually no limit to what can be used for the abrasive materials 26 as long as it is retained in the container 12.
Most materials selected as the abrasive materials 26 are given preference if they tend not to adhere to the skin of the foot 24. This ensures that the abrasive materials 26 remain in the container 12 and are not transported out when the person leaves the shower 18 area. The user may also elect to slightly raise the foot 24 for a short period of time and allow water coming from the shower 18 to rinse any remaining abrasive material 26 off of the foot 24 and back into the container 12 before exiting.
Water from the shower 18 flows through the lining 32, around and through the foam 28, and out through the openings 20 in the bottom of the container 12 while maintaining the abrasive materials 26 in the container 12 on top of the lining 32. If any of the abrasive materials 26 pass through the lining 32 they are prevented from embedding in the foam 28 by the second netting 30 and from passing out through the openings 20 by the first netting 22. It is not desirable to have the abrasive materials 26 clog a shower stall or bath tub drain.
Periodically, the cords 36 are loosened and the abrasive materials 26 and the lining 32 and the foam 28 are removed for rinsing and drying. They are either then reused or replaced, when required.
The invention has been shown, described, and illustrated in substantial detail with reference to the presently preferred embodiment. It will be understood by those skilled in this art that other and further changes and modifications may be made without departing from the spirit and scope of the invention which is defined by the claims appended hereto.
