BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to scrubbing devices and, more particularly, to a portable, lightweight exfoliating apparatus adapted for stationary, callus-removal operation.
2. Description of the Related Art
Calluses and corns are areas of thick, hardened, dead skin. They form to protect the skin and body structure under the skin from pressure, friction, and injury. Calluses generally form on the palms of the hands or the soles of the feet when the epidermis thereof becomes partially keratinized due to repeated pressure or friction on an area of skin over time. The pressure causes the skin to die and form a hard, protective surface.
Calluses on the hands are often caused by the regular handling of an object that puts pressure on the hand, such as tools or sports equipment. Calluses and corns on the feet are often caused by pressure from footwear such as tight shoes, high-heeled shoes, loose shoes, and thin-sole shoes. Walking barefoot can also cause calluses. The outer edge of the big toe and the sides of the heel are the most common areas for callused feet.
Calluses and corns can cause discomfort and can also become painful. Thus, it is often necessary to periodically remove such calluses from the palms of the hands, elbows or soles of the feet. Traditionally, a pumice stone or a mechanical sander device have been employed for manually filing the calluses and corns in order to facilitate their removal. However, these conventional methods and apparatuses for callus removal require the use of ones hands and bending over. Furthermore, such methods and apparatuses are time consuming, laborious, inefficient, and often painful.
Accordingly, a need has arisen for a stationary, foot-operated exfoliating device adapted to allow for the removal of calluses in a manner which is quick, easy, efficient and painless. The development of the exfoliating apparatus fulfills this need.

Theapparatus10 comprises a base12 having at least oneleg14 depending from the underside of thebase12, and at least oneabrasive regions16 coupled to the topside of thebase12. Theapparatus10 may be placed or positioned so that the leg(s)14 are fixedly secured to a surface, thereby inhibiting movement of theapparatus10 during use. Once theapparatus10 is in position, a user may exfoliate his/her foot by passing the foot over the abrasive region(s)16 in a longitudinal path (forward and backward relative to the user's orientation), which may be repeated with additional abrasive region(s)16 of varying texture grade if so desired and if so provided.
It is envisioned that theapparatus10 may comprise a plurality of legs14 (as depicted inFIG. 1, with the legs denoted by14a,14b,14cand14d,respectively), and/or a plurality of abrasive regions16 (as depicted inFIG. 6, with the abrasive regions denoted by16a,16band16c,respectively).
The base12 may comprise a variety of shapes or forms, dimensions, materials, and combinations thereof. For instance, it is envisioned that the base12 may have an orthogonal, circular or elliptical shape, among other forms. The outer margin(s) of the base12 may have a beveled and/or rounded edge to decrease the likelihood of injury. It is further envisioned that the base12 may have a variety of dimensions, especially dimensions conducive for use within a tub or shower. In one embodiment, thebase12 comprises an orthogonal form having the dimensions 7″ (height)×9″ (width)×¼″ (thickness). The height, width and/or thickness may vary in accordance with tub or shower widths. It is further envisioned that the base12 may comprise a variety of materials, including a number of plastic materials, and including transparent or translucent materials, or non-corrosive metal materials, or combinations thereof. Additionally, it is also envisioned that the base12 may comprise a variety of aesthetics, including a variety of solid colors, clear or translucent, multi-color patterns, and indicium or indicia (including the use of licensed trademark(s)).
An underside of the base12 may also include apliable abutment boss40 suitably attached centrally thereto. During use of theapparatus10, thepliable abutment boss40 functions to provide centralized subjacent support to the base12 whenbase12 is secured to a selected surface.
The leg(s)14 may comprise a variety of devices. In one embodiment, the leg(s)14 may comprise a durable silicone or other plastic-basedsuction cup15, to which pressure may be applied to generate a secure seal between the stall surface and thesuction cup15. In another embodiment, the leg(s)14 may comprise a leg or post having an adhesive material affixed to the end engaging the stall surface. Eachleg14 is secured to the base via a threaded bolt or stud and a non-corrosive nut coupled thereto. It is envisioned that other similar devices and substitutes may be utilized to achieve the same effect and function without departing from the scope of the disclosure and the claims herein.
Referring now toFIGS. 2-7, theabrasive region16 is positioned along the topside of thebase12, thereby easily accessed by the user. Theabrasive region16 may comprise a single abrasive sheet of a particular texture grade (seeFIG. 5), a single abrasive sheet having a plurality of varying texture grades (seeFIG. 2), or a plurality of abrasive sheets of varying texture grades (seeFIG. 6 andFIG. 7, respectively), and is discussed in greater detail below. The abrasive region(s)16 may be coupled to thebase12 by a variety of means, including the use ofhook24 andloop26 material. For instance, and but one example of the possibilities available, a complementary set of hook and loop material strips18 and20, each having anadhesive agent28 along the backside of each protected by a removable protective backing, may be used so that one of either the hook or theloop material strip18 or20 is adhered to the base and the remaining one of either the hook or theloop material strip18 or20 is adhered to the underside of an abrasive sheet used as at least a portion of the abrasive region(s)16. In such a configuration, the complementary hook and loop material strips18 and20 may be coupled or interlocked so that subjacent material firmly (such as hook material adhered to the base) and securely maintains the superjacent material (such as loop material adhered to the underside of the abrasive sheet) into a fixed position during use. Additionally, in such a configuration, the abrasive sheet(s) of the abrasive region(s)16 is/are removable by separating thehook24 andloop26 material and substituting a new and/or different texture grade abrasive sheet as desired. It is envisioned that hook and loop material strips18 and20 may be oriented or sized so that the hook or loop material adhered to the underside of the abrasive sheet has an excess oroverhang22 relative to the hook or loop material adhered to the topside of thebase12. The excess oroverhang22 provides means for easy disposal and replacement of the exhausted abrasive sheet of the abrasive region(s)16, wherein the user grasps the excess oroverhang22 and separates the hook and loop material, thereby releasing the abrasive sheet from theabrasive region16. It is envisioned that each one of theabrasive regions16 utilizes a water-resistant paper base abrasive sheet so as to extend the life of the abrasive sheet(s) and the abrasive region(s)16 for use in a bath or shower.
In one embodiment, as described above, and as depicted inFIG. 5, theabrasive region16 comprises a single abrasive sheet having a single texture grade, which may comprise coarse, fine or intermediate textures, thereby giving the user flexibility in choice. In another embodiment, as described above, and as depicted inFIG. 6, theabrasive region16 comprises a single abrasive sheet having a plurality of texture grades sheets disposed thereon, and denoted byreference characters16a,16band16c,respectively. In such an embodiment, having at least two abrasive regions (and depicted as three regions), the user is given the opportunity to utilize more than one texture grade for treatment. It is envisioned that theabrasive regions16a,16band16cmay be separated by indicia for the user's convenience. In a related embodiment, theapparatus10 shown inFIG. 7 utilizes a plurality of distinctiveabrasive regions16, and illustrates threeabrasive regions16 utilizing three distinctive abrasive sheets (also usingreference characters16a,16band16c,respectively).
In the embodiments depicted inFIG. 6 andFIG. 7, it is envisioned that16amay comprise a coarse texture grade,16bmay comprise an intermediate texture grade, and16cmay comprise a fine texture grade. In this configuration, the most preferable sequence would begin with16a,then move to16b,and finish with16c.Thecoarse texture grade16ais utilized in removing the build-up of hard skin calluses. Theintermediate texture grade16bis utilized in softening the skin after the bulk of the callus(es) have been removed. Thefine texture grade16cis utilized for completely removing any rough portions or edges from the skin once the coarse and intermediate grades have been utilized.
Referring now toFIG. 8, theapparatus10 may further comprise an open-cell sponge attachment30. Theattachment30 may comprise a hook orloop material strip18 or20 applied to the underside of the attachment, the hook orloop material strip18 or20 complementary to the existing hook orloop material strip18 or20 applied to the topside of thebase12. Theattachment30 may be substituted for theabrasive region16, or one of theabrasive regions16a,16bor16cas depicted inFIG. 7, and utilized for the application of a lotion, oil, or topical medicine to the foot or feet. In such an application, the lotion, oil or topical medicine is placed onto the top surface of the sponge, and the user passes the foot or feet over the sponge in a manner similar to that utilized with regard to the abrasive region(s)16. As the foot or feet is/are passed over the sponge, the lotion, oil and/or medicine is transferred to the foot or feet.
Referring now toFIG. 9, theapparatus10 may further comprise an attachable anddetachable platform32 comprising abase34 of smaller dimension than thebase12 of theapparatus10. The base34 may comprise at least oneleg36 coupled to the underside of thebase34. A hook orloop material strip18 or20 is applied to the topside of thebase34, and complementary hook or lookmaterial strip18 or20 is applied to the underside of an abrasive sheet orregion38, wherein the hook and loop material strips18 and20 cooperatively couple the abrasive sheet orregion38 to thebase34.
Referring now toFIG. 10 andFIG. 11, theapparatus10 may further comprise a semicircular exfoliatingattachment50 defining an elongated configuration. Thesemicircular exfoliating attachment50 may comprise a hook orloop material strip18 or20 applied to the underside thereof, with the hook orloop material strip18 or20 complementary to the existing hook orloop material strip18 or20 applied to the topside of thebase12. Thesemicircular exfoliating attachment50 includes anabrasive region16 coupled to the outer externalcircumferential surface51 thereof. Theabrasive region16 may comprise a single abrasive sheet of a particular texture grade. Thesemicircular exfoliating attachment50 may be substituted for theabrasive region16, or one of theabrasive regions16a,16bor16cas depicted inFIG. 7, and is utilized for exfoliating particularly the arch and outer edges of the foot or feet.
It is envisioned that theapparatus10 may be retrofit to an existing tub or shower stall, or integral to a tub/shower stall. It is envisioned that the floor surface of the stall is the expected placement, although installation at other locations is envisioned, such as along the front wall just below the faucet, angled for ease of use. It is also envisioned that theapparatus10 may be installed in the floor of the tub or shower stall with a removable panel recessed just below the surface of the floor, and having a drain line running from recess into standard drain line of the tub or shower stall.
2. Operation of the Preferred EmbodimentTo use the present invention, user fixedly secures the exfoliatingapparatus10 via thesuction cups15 thereof at a desired location such as the floor surface of the tub/shower stall or along the front wall just below the faucet. User next exfoliates his/her foot, hand, or elbow by passing the foot, hand, or elbow over the abrasive region(s)16 in a longitudinal path, which may be repeated with additional abrasive region(s)16 of varying texture grade if so desired. More specifically, user slides his/her foot, hand, or elbow forward and backward relative to the user's orientation against thecoarse texture grade16afor removing the build-up of hard skin calluses.
