(12) The abrasion sheet 110 of the abrasive hygiene apparatus, shown in FIG. 3, comprises a top surface 111 and a bottom surface (not shown). The top surface 111 further comprises a roughened texture pattern composed of raised geometric structures including, but not limited to, pyramidal, hemispheric, trapezoidal, or irregular polygonal structures. A person of ordinary skill in the art would understand that the texture pattern may comprise a randomized mixture, gradient, hierarchal, homogenous, or uniformly continuous configuration of geometric structures. A person skilled in the art would also appreciate that the various pattern configurations may be disposed upon multiple abrasion sheets, based on a desired result by a user or manufacturer.

(13) The abrasion sheet 110 is composed of a durable corrosion-resistant material, including but not limited to metal or metal alloy. The abrasion sheet is further configured to be non-pliable, promoting structural stability of the apparatus. A bottom surface (not shown) of the abrasion sheet 110 comprises at least one bracket member 115 extended from at least one edge of the abrasion sheet 110. At least one bracket member 115 projects first downward from the abrasion sheet 110 and then laterally towards a central planar axis of the abrasion sheet 117. The at least one bracket member 115 thus forms an attachment channel 118 with the abrasion sheet 110. The attachment channel 118 is configured to facilitate removable coupling of the abrasion sheet 110 to the frame 120.

(14) The frame 120 of the abrasive hygiene apparatus 100, shown in FIGS. 4-5, comprises a top and bottom surface similarly dimensioned to that of the abrasion sheet 110, but may be marginally larger or smaller in some dimensions to facilitate coupling capabilities. The frame 120 further comprises a plurality of grooves 123 disposed upon the top surface 121 and configured to facilitate decoupling of the abrasion sheet 110 from the frame 120. The frame further comprises at least one ridge structure 125 coupled to at least one edge of the frame. At least one ridge structure 125 projects perpendicularly from a surface of the frame 120, configured to retain the abrasion sheet 110 to the frame 120. At least one ridge structure 125 is further configured to form a gripping surface for a user during adjustment and use of the apparatus 100.

(15) The frame 120 is composed of an impact-resistant material, configured to absorb and withstand considerable amounts of impact forces and promote structural stability of the apparatus 100. Such substantial impact forces may include a downward or lateral force transferred by a foot of a user during use of the apparatus 100. A person skilled in the art would appreciate that suitable frame materials may include but are not limited to; polycarbonate (PC), polyphenylsulfone (PPSU), acrylonitrile butadiene styrene (ABS), or other durable thermoplastics.

(16) The abrasive hygiene apparatus 100 further comprises an engagement sheet 130, shown in FIG. 6, removably coupled to the bottom surface (not shown) of the frame 120. The engagement sheet 130 comprises a top and bottom surface of similar dimensions to the abrasion sheet 110 and is configured to facilitate grip between the abrasive hygiene apparatus 100 and another surface. The engagement sheet 130 may be composed of any durable material with enhanced frictional characteristics, including by not limited to, polyvinyl chloride, polybutadiene, or styrene-butadiene. In some embodiments of the invention, the engagement sheet 130 may include an anti-slip coating such as a polyurea, a polyaspartic, or a polymeric aggregate coating.

(17) In some embodiments of the invention, the abrasive hygiene apparatus 100 comprises a semi-circular slit disposed through both the engagement sheet 130 and the frame 120, configured to allow decoupling of an individual component from the rest of the assembled apparatus 100.

(18) In some embodiments of the invention, the abrasion sheet 110 may be removed from the apparatus 100 and replaced with an abrasion sheet comprising a different surface texture pattern configuration, depending on current needs of the user.

(19) In another embodiment of the invention, as shown in FIG. 7, the abrasion sheet 110 and the frame 120 may comprise a single structure 140, the top surface 121 of the frame 120 having a roughened texture pattern composed of raised geometric structures including, but not limited to, pyramidal, hemispheric, trapezoidal, or irregular polygonal structures. A person of ordinary skill in the art would understand that the texture pattern may comprise a randomized mixture, gradient, hierarchal, homogenous, or uniformly continuous configuration of geometric structures. The single structure 140 may be composed of a durable corrosion-resistant material, including but not limited to metal or metal alloy, and configured to be non-pliable, promoting structural stability of the apparatus.

(20) The single structure 140, as shown in FIG. 8, may further comprise at least one channel 145 disposed along at least one lateral surface. The at least one channel 145 is configured to facilitate user grip and allow a different abrasion sheet to be coupled thereto by engaging a bracket member 115 of the abrasion sheet 110 with the at least one channel 145 of the single structure 140. This configuration allows one abrasion sheet having a particular surface texture pattern to be used and stored atop a single structure having a different surface texture pattern to further allow user choice and interchangeability of multiple abrasion sheets with differing surface texture patterns.

(21) The method of using the abrasive hygiene apparatus 100 comprises a user first placing the fully assembled apparatus upon a desired operating surface, such as a floor, engaging the engagement sheet 130 with the surface. The user then places a bare foot on the top surface of the abrasion sheet 110 of the apparatus, engaging an epidermal surface of the foot with the roughened surface of the sheet 110. The user then moves the foot laterally in multiple directions, facilitating abrasive interaction between the foot and the abrasion sheet 110. This action facilitates callous removal, debris build-up removal, dry or cracked skin prevention, and skin exfoliation promotion.

(22) When finished, the user may disengage the foot from the apparatus. Next the user may then grip the ridge structures 125 of the frame 120 and remove the apparatus from the operating surface in preparation for cleaning or storage of the apparatus.

(23) To perform cleaning, maintenance, or component replacement of the apparatus, the user may first disengage the engagement mat 130 from the frame 120. The user then disengages the abrasion sheet 110 from the frame 120. Once each component of the apparatus is disengaged from one another, and the apparatus disassembled, the user may then perform the desired cleaning, maintenance, or replacement. To reassemble the apparatus, the user may perform the aforementioned steps in reverse order until the apparatus is complete again. The above described steps for cleaning, maintenance, or replacement may be performed by a user in any desired order such that the result is a fully assembled or fully disassembled apparatus.

(24) While the invention has been described with respect to various embodiments, it will be understood that the invention is capable of further modifications. This application is intended to cover any variations, uses, or adaptations of the invention generally following the principles of the invention, and includes such departures from the present disclosure within the known and customary practice in the art to which the invention pertains.
