DETAILED DESCRIPTION OF THE INVENTION

(7) All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

(8) The present invention is a foot and ankle strengthening device that is used to provide stimulus to muscles typically weakened in people who suffer from various foot and ankle problems, particularly plantar fasciitis. The present invention utilizes a pair of angled surfaces to reinforce healthy foot arches, and a block as the primary support. The present invention comprises a first foot-bracing platform 1, a second foot-bracing platform 5, a textured roller 6, and an elongated balance block 12, as seen in FIG. 1. The first foot-bracing platform 1 is a surface against which a user may place a foot for support and appropriate positioning. Similarly, the second foot-bracing platform 5 provides, in the preferred usage of the present invention, a surface for the user's opposite foot. The textured roller 6 is a generally cylindrical device that enables the user to apply targeted pressure to specific pieces of the user's foot or ankle. The elongated balance block 12 is a generally rectangular prism-shaped protrusion that, in the preferred usage of the present invention, provides the contact point with the ground.

(9) These components together enable the present invention to provide an appropriate muscular-skeletal stimulus for the user's ankles and feet. The first foot-bracing platform 1 and the second foot-bracing platform 5 each comprise a proximal edge 2 and a distal edge 3. The proximal edge 2 is the edge closest to the space between the first foot-bracing platform 1 and the second foot-bracing platform 5. The distal edge 3 is the edge furthest from the space between the first foot-bracing platform 1 and the second foot-bracing platform 5. The proximal edge 2 of the first foot-bracing platform 1 and the proximal edge 2 of the second foot-bracing platform 5 are positioned adjacent to each other. The first foot-bracing platform 1 and the second foot-bracing platform 5 are therefore positioned adjacent to each other, thus enabling the user to stand with feet positioned near each other.

(10) The textured roller 6 is rotatably mounted between the proximal edge 2 of the first foot-bracing platform 1 and the proximal edge 2 of the second foot-bracing platform 5. In this way, the textured roller 6 is positioned to be equally accessible for each of the user's feet. Further, this positioning provides the textured roller 6 support across the present invention, thus allowing the user to utilize the textured roller 6 for ankles and foot muscles while standing adjacent to the first foot-bracing platform 1 and the second foot-bracing platform 5. The elongated balance block 12 is mounted between the distal edge 3 of the first foot-bracing platform 1 and the distal edge 3 of the second foot-bracing platform 5, as seen in FIG. 2. Thus, the elongated balance block 12 is positioned to provide support across the present invention from the ground or other preferably flat surface upon which the present invention rests. Furthermore, the elongated balance block 12 is centrally positioned along the distal edge 3 of the first foot-bracing platform 1 and the distal edge 3 of the second foot-bracing platform 5. In this way, the elongated balance block 12 is positioned to provide unstable support. This is desirable, as instability requires the user to activate relevant core muscles to maintain balance.

(11) A sagittal plane 15 is positioned in between the first foot-bracing platform 1 and the second foot-bracing platform 5. The sagittal plane 15 is a geometric plane which divides the present invention roughly in half. The first foot-bracing platform 1 is oriented at a first interior acute angle 16 with the sagittal plane 15, as seen in FIG. 3. This arrangement ensures that the first foot-bracing platform 1 is at an angle appropriate for supporting the user's foot. Similarly, the second foot-bracing platform 5 is oriented at a second interior acute angle 17 with the sagittal plane 15. In this way, the second foot-bracing platform 5 is at an angle appropriate for supporting the user's foot opposite the first foot-bracing platform 1. The elongated balance block 12 is positioned normal to the sagittal plane 15. Thus, the elongated balance block 12 is arranged to provide instable support for the present invention.

(12) The user experience may improve through the inclusion of gripping features and mechanisms for the user's foot. To this end, the present invention further comprises a first textured layer 18, as seen in FIG. 4. The first textured layer 18 is a high-friction surface that may further include a variety of features, including, but not limited to, bumps, ridges, crevices, and more. The first textured layer 18 is connected across the first foot-bracing platform 1, opposite the elongated balance block 12. This arrangement provides a foot of the user with ample traction for remaining upon the first foot-bracing platform 1.

(13) Furthermore, the user may also benefit from the inclusion of assistive features for the other foot of the user. To this end, the present invention further comprises a second textured layer 19, as seen in FIG. 4. The second textured layer 19 is a high-friction surface that may further include a variety of features, including, but not limited to, bumps, ridges, crevices, and more. The second textured layer 19 is connected across the second foot-bracing platform 5, opposite the elongated balance block 12. This arrangement provides a foot of the user with ample traction for remaining upon the second foot-bracing platform 5.

(14) The textured roller 6 further benefits from employment of features that can improve the user's ability to interact with soft tissue in the user's feet and ankles. To this end, the present invention further comprises a plurality of grip-enhancing features 20, as seen in FIG. 6. The plurality of grip-enhancing features 20 is a set of shaped devices, including, but not limited to, bumps, ridges, and other such features that provide unique stimulus to muscular groups. The plurality of grip-enhancing features 20 is laterally connected around the textured roller 6. In this way, the user may control specific stimulus received by areas of the user's foot or ankle area while using the textured roller 6.

(15) The plurality of grip-enhancing features 20 is particularly effective in specific configurations. To this end, in an exemplary embodiment, each of the plurality of grip-enhancing features 20 is configured into a hexagonal prism, as seen in FIG. 6. This arrangement provides edges and crevices that are advantageous to providing useful acute pressure to specific foot and ankle areas.

(16) The textured roller 6, which can be utilized to apply acute or broad pressure to specific regions of the foot or ankle, is made more effective through the employment of components that enable thermal engagement of muscular groups, thus allowing for improved blood flow in areas of interest. To this end, the textured roller 6 comprises a thermally-conductive housing 7 and a thermally-resistive core 8, as seen in FIG. 5. The thermally-conductive housing 7 is a generally cylindrical component that is made of any of a variety of thermally-conductive materials, thus enabling rapid transition between low and high temperatures. The thermally-resistive core 8 is a preferably cylindrical device made of thermally-resistive materials capable of retaining temperature. The thermally-resistive core 8 is mounted within the thermally-conductive housing 7. This arrangement enables proximity between the thermally-conductive housing 7 and the thermally-resistive core 8. The thermally-resistive core 8 is in thermal communication with the thermally-conductive housing 7. This arrangement enables the thermally-resistive core 8 to transfer heat to the thermally-conductive housing 7. The connection between the thermally-resistive core 8 and the thermally-conductive housing 7 allows for the transfer of both high temperatures as well as low temperatures. In this way, the textured roller 6 can be used to apply hot or cold temperatures to target areas depending upon the environment in which the thermally-resistive core 8 is placed. Placing and leaving the thermally-resistive core 8 into a refrigerator or freezer allows the thermally-resistive core 8 to retain and transmit low temperatures, while storing the thermally-resistive core 8 in an oven or other high temperature space allows the thermally-resistive core 8 to transmit hot temperatures to the thermally-conductive housing 7.

(17) The elongated balance block 12 must be adequately shaped to provide the structural support required to stimulate the user's foot and ankle muscles appropriately. To achieve this, the elongated balance block 12 comprises a first block end 13 and a second block end 14, as seen in FIG. 3. The first block end 13 is the section of the elongated balance block 12 that receives pressure when the user shifts balance towards the first foot-bracing platform 1. Conversely, the second block end 14 is the section of the elongated balance block 12 that receives pressure when the user shifts balance towards the second foot-bracing platform 5. The first block end 13 is positioned offset from the distal edge 3 of the first foot-bracing platform 1. This arrangement allows the user to activate muscles required for balancing along the first block end 13. Similarly, the second block end 14 is positioned offset from the distal edge 3 of the second foot-bracing platform 5. This arrangement allows the user to activate muscles required for balancing along the second block end 14. The first block end 13 and the second block end 14 may be shaped to provide a more advantageous muscular stimulus. For example, the first block end 13 and the second block end 14 may be rounded, chamfered, ridged, bumped, or shaped in a variety of other ways.

(18) The textured roller 6 must be rotatably connected between the first foot-bracing platform 1 and the second foot-bracing platform 5 in order to ensure that the user may access the textured roller 6 to provide acute soft tissue activation. To achieve appropriate connection, the present invention further comprises a roller mount 21, as seen in FIG. 5. The roller mount 21 is at least one fixture capable of enabling a rotatable connection to the rest of the relatively stationary present invention. The roller mount 21 may include various structures for positioning the textured roller 6, as well as bearings, bushings, or other components capable of enabling rotatable connection to the present invention. The roller mount 21 is integrated in between the proximal edge 2 of the first foot-bracing platform 1 and the proximal edge 2 of the second foot-bracing platform 5. This positioning is optimal for enabling desirable mounting of the textured roller 6. The textured roller 6 is rotatably attached into the roller mount 21. This arrangement enables the textured roller 6 to rotate in position relative to the first foot-bracing platform 1 and the second foot-bracing platform 5.

(19) In an exemplary embodiment, the present invention is equipped to support and even partially suspend the textured roller 6 over the first foot-bracing platform 1 and the second foot-bracing platform 5. To achieve this, the textured roller 6 further comprises a first mounting protrusion 9, a second mounting protrusion 10, and a roller body 11, as seen in FIG. 1, as seen in FIG. 6. The first mounting protrusion 9 relates to a rigid structure that extends generally above the proximal edge 2 of the first foot-bracing platform 1 and the proximal edge 2 of the second foot-bracing platform 5. Similarly, the second mounting protrusion 10 relates to a rigid structure that extends generally above the proximal edge 2 of the first foot-bracing platform 1 and the proximal edge 2 of the second foot-bracing platform 5. The roller body 11 relates to the physical volume of space occupied by the textured roller 6. The first mounting protrusion 9 is terminally connected to the roller body 11. This allows the first mounting protrusion 9 to support the roller body 11 in position within or above the present invention. Similarly, the second mounting protrusion 10 is terminally connected to the roller body 11. This allows the second mounting protrusion 10 to support the roller body 11 in position within or above the present invention. The first mounting protrusion 9 and the second mounting protrusion 10 are rotatably engaged to the roller mount 21. This arrangement ensures that the roller body 11 is capable of rotating relative to the roller mount 21.

(20) The first interior acute angle 16 may be any angle that is acute between the sagittal plane 15 and a perpendicular plane; however, a particular range of angles is generally considered most effective at providing desired muscular activation. To this end, the first interior acute angle 16 is in a range between 70 arc degrees and 80 arc degrees, as seen in FIG. 3. This range ensures both effectiveness and comfort for the user during use. Similarly, the second interior acute angle 17 is in a range between 70 arc degrees and 80 arc degrees. Together, this arrangement of the first interior acute angle 16 and the second interior acute angle 17, particularly in the exemplary embodiment in which the first interior acute angle 16 and the second interior acute angle 17 are equivalent angles, facilitates muscular stimulation without overwhelming or overstressing joints and ligaments.

(21) The first foot-bracing platform 1 and the second foot-bracing platform 5 may function at a variety of different sizes; however, the first foot-bracing platform 1 and the second foot-bracing platform 5 are optimally of specific dimension ranges. To this end, the first foot-bracing platform 1 and the second foot-bracing platform 5 each comprise a platform body 4, as seen in FIG. 1. The platform body 4 is the physical volume of space occupied by each of the first foot-bracing platform 1 and the second foot-bracing platform 5. The width of the platform body 4 is preferably in a range between 6 inches (15.24 centimeters) to 12 inches (30.48 centimeters). This arrangement ensures ample breadth for the user's foot. Similarly, the length of the platform body 4 is preferably in a range between 12 inches (30.48 centimeters) to 18 inches (45.72 centimeters). In this way, the present invention has ample lateral space for feet of various sizes.

(22) Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
