DETAILED DESCRIPTION

[0044] The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments or the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to make or use the embodiments of the disclosure and are not intended to limit the scope of the disclosure, which is defined by the claims. For purposes of description herein, the terms “upper”, “lower”, “left”, “rear”, “right”, “front”, “vertical”, “horizontal”, and derivatives thereof shall relate to the invention as oriented in FIG. 1. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

[0045] Referring now to FIGS. 1-6, there is illustrated an exemplary embodiment of a callus removal apparatus, generally designated 100, in accordance with aspects of the present invention. The illustrated callus removal apparatus 100 includes a main body 102, a callus scraping device 104, and a callus sanding device 106. The main body 102 has opposite first and second end portions 108, 110. Also, the main body 102 is hollow, made from a suitable plastic or metal, and of an elongated cylindrical shape for ease of gripping with one hand. The callus scraping device 106 is made of a suitable metal and fitted on the first end portion 108 of the main body 102. The callus sanding device 106, in part, is made of a suitable plastic or metal and fitted on the second end portion 110 of the main body 102.

[0046] More particularly, as best seen in FIGS. 4 and 6, the first end portion 108 of the main body 102 has an annular end face 112 and an annular ledge 114 on the inside of the first end portion, being spaced longitudinally along the first end portion 108 from the annular end face 112 and extending inwardly from the first end portion such that an annular recess 116 is formed on the inside of and about the first end portion 108 and extends longitudinally from the annular end face 112 to the annular ledge 114. As best seen in FIGS. 3 and 6, the second end portion 110 of the main body 102 has an annular end face 118 and an annular ledge 120 on the outside of the second end portion, being spaced longitudinally along the second end portion 110 from the annular end face 118 and extending outwardly from the second end portion such that an annular recess 122 is formed outside of and about the second end portion 110 and extends longitudinally from the annular end face 118 to the annular ledge 120.

[0047] The callus scraping device 104 basically includes a head 124 having an exterior face 126, and an array of spaced apart annular edges 128 exposed at the exterior face that form a plurality of spaced apart apertures 130 extending through the head 124. The exterior face 126 being of convex or dome shape and the spaced apart annular-shaped edges 128 being exposed at the exterior face of the head 124 renders the edges 128 in the exterior face 126 capable of contacting and removing pieces of a callus by gripping the main body 102 with one hand and moving and scraping its head 124, in any direction, across and in contact with a callus, such as shown in FIG. 8. In the one exemplary embodiment seen in FIGS. 1, 4 and 5, the spaced apart apertures 130 are aligned in a plurality of rows intersecting at and radiating outward from a central one of the apertures. Also, the dome-shaped head 124 with the annular edges 128 may be in the form of a cutting screen.

[0048] The head 124 of the callus scraping device 104 also has an interior face 132 and an annular peripheral rim portion 134 surrounding the exterior and interior faces 126, 132 and the plurality of spaced apart apertures 130 which extend between the exterior and interior faces of the head. The callus scraping device 104 also includes a connector 136 in the form of a plurality of legs 138 arranged spaced apart from one another in a circular row and fixedly attached to the interior face 132 of the head 124, inwardly of the annular peripheral rim portion 134 of the head and surrounding the plurality of spaced apart apertures 130, so as to extend away from the head. The legs 138 are made of a resilient springy material so that they will yield sufficiently inwardly to snugly fit within the first end portion 108 of the hollow main body 102 as at least one of the annular peripheral rim portion 134 of the head 124 makes contact with the annular end face 112 of the main body 102 or the connector 136 at a rear end thereof makes contact with the annular ledge 114 on the inside of the first end portion 108 of the main body.

[0049] The callus sanding device 106 basically includes a panel 140 having an exterior face 142, and a plurality of sanding particles 144 attached on the exterior face of the panel and exposed at the exterior thereof and thus capable of contacting, and removing pieces of, a callus by gripping the main body 102 with one hand and moving the panel 140 across and in contact with the callus, as shown in FIG. 7. The panel 140 with the sanding particles 144 may be in the form of a piece of 80 GHT sandpaper. Alternatively, the callus removal apparatus 100 may have a hollow end cap 146, with or without the sanding panel 140, fitted on and enclosing the second end portion 110 of the main body 102. The end cap 146 may also be detachable from the second end portion 110 of the main body 102 to remove callus pieces from the hollow main body.

[0050] The panel 140 of the callus sanding device 106 also has an interior face 148 and an annular peripheral rim portion 150 surrounding the exterior and interior faces 142, 148 and the plurality of sanding particles 144 on the exterior face. The callus sanding device 106 may also be joined with the hollow end cap 146 received in the annular recess 122 so as to snugly fit about the outside of the second end portion 110 of the main body 102 as at least one of the annular peripheral rim portion 150 of the panel 140 supported at one end 152 of the hollow end cap 146 makes contact with the annular end face 118 of the second end portion 110 of the main body 102 or an opposite end 154 of the hollow end cap 146 makes contact with the annular ledge 120 on the outside of the second end portion 110 of the main body 102. The main body 102 also has an annular groove 156 formed in the second end portion 110 and about the annular recess 122, and an O-ring 158 seated and compressed in the annular groove 156 when the hollow end cap 146 is snugly fitted along the annular recess 122 about the outside of the second end portion of the main body. The presence of the annular groove 156 and O-ring 158 enables ease of removal and replacement of the end cap 146 from and back on the second end portion 110 of the main body 102 of the callus removal apparatus 100.

[0051] The above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the invention. Many variations, combinations, modifications or equivalents may be substituted for elements thereof without departing from the scope of the invention. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all the embodiments falling within the scope of the appended claims.
