DETAILED DESCRIPTION
It should be understood at the outset that although an exemplary implementation of the present invention is illustrated within, the present invention may be implemented using any number of techniques, materials, designs, and configurations whether currently known or in existence. The present invention should in no way be limited to the exemplary implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein.
The athletic shoe (FIG. 19), as is true of most footwear, may be generally described as having the sole 4 and an upper part 5. The upper part may be constructed of virtually any material such as, for example, leather, plastic, or canvas. The sole may include three parts: an innersole or insole 6 a midsole 8; and an outer sole or outsole 4. The insole may provide added cushion and may or may not be removable. The outsole 4 will preferably be made of a durable material such as rubber, and may have a textured surface such as textured or raised bumps, to provide added traction. The midsole 8 will generally be constructed of a softer “cushiony” material and will generally be thicker than the insole and the outsole 4. In some embodiments, however, the sole 4 will comprise only one part, such as the leather sole of a loafer. In other embodiments, the sole may include a separate heel or wedge that elevates the rear portion of the footwear, such as the heel of a leather wingtip dress shoe or wedge. This heel or wedge 8 may be considered to be part of the heel portion of the sole. It should be understood that the present invention might be implemented in virtually any footwear, irrespective of the design or the make-up of the sole. Various styles of footwear and methods of making footwear are known in the art and are known by one of ordinary skill in the art.
In most footwear, including the athletic shoe (FIG. 19), the sole may also be divided into three portions or regions: (1) the heel portion, (2) an arch portion, and (3) a forefoot portion. It should be understood that 1) the heel portion, (2) an arch portion and (3) a forefoot portion of the sole are incapable of being exactly defined and located, and that such portions vary from one footwear type to another. Thus, the location, the boundaries between, and the size of the heel portion, the arch portion, and the forefoot portion of the sole are only rough approximations.
The wheel may be constructed or made of virtually any known or available material. Such as, for example, a urethane, a plastic, a polymer, a metal, an alloy, a wood, a rubber, a composite material, and the like. This may include, for example, aluminum, titanium, steel, and a resin. Preferably, the material will be durable, provide quiet performance, provide some traction on the surface and will provide a soft or cushioning feel.
The wheel and the wheels are illustrated as cylindrical wheels. These wheels, however, may be provided in virtually any available configuration. Further, one or more wheels may be positioned in a section of the board.
FIG. 1B further illustrates other elements of the wheel assembly that include a first member and a second member of a mounting structure that is used to removably couple with an axle 9. The axle 9 extends through the wheel 10 such that the wheel is rotatably coupled or mounted to the axle 9. This preferably involves the use of precision bearings 11, such as high performance precision bearings 11, provided in a recess 12, such as an annular recess 12, one side of the wheel. A first precision bearing 11 and a second precision bearing 11 may be ABEC grade precision bearings and are illustrated with hidden lines and positioned in the first recess 10 and second recess 12 of the wheel.
The axle 9 may be made of any material that provides suitable physical characteristics, such as strength and weight, to name a few. The axle 9 is preferably made of hardened steel, is cylindrical in shape, each end is rounded, and is removably or permanently coupled with a first member and a second member, respectively, of the mounting structure 13, 16. The removable or permanent coupling between each end of the axle and the first member and these members may be achieved by any known or available mechanism.
It should also be noted that because the weight of the user of the apparatus will exert a significant downward force and the ground or surface will exert an equal force upward, the axle 9, and, hence, the wheel 10 will generally be forced into place. Thus, the present invention does not require a large side force to keep the axle 9 and the wheel 10 in place.
FIG. 1B Shows a “c-clip” 14, slip ring 14, or ring clip 14 is positioned around, or nearly around, the axle 9 near the precision bearing 11. This serves to ensure that the precision bearing 11 remains in place in the recess of the wheel 12. The slip clip 14 or ring clip 14 will preferably be positioned on the axle 9 through a groove. Such as a radial groove or radial indentation, in the axle. It should be understood, however, that one of ordinary skill in the art may use any of a variety of other arrangements to ensure that the precision bearing 11 stays in position. In alternative embodiments, the precision bearing 11 may be eliminated or loose bearings may be used.
FIG. 1A is a perspective views of a wheel assembly that includes the wheel 10 rotatably mounted to the axle 9.
It should be understood that the axle 9 may couple to a member of a mounting structure using any available technique and in virtually an unlimited number of ways. For example, an axle may couple to the first member and the second member by way of a threaded axle and bolt. A mounting structure may move from a retracted position to an extended position through a spring arrangement.
FIG. 5A, 5B illustrates a method for use of the wheeled platform apparatus 30 on a surface by a user, wherein the user positions a first foot on the wheeled platform apparatus and moves on the surface in a first direction (i.e., rolling direction of the wheeled platform apparatus 30) by placing at least a portion of the second foot in contact with the surface and kicking or pushing the portion of the shoe to provide force in the first direction.
FIG. 6 illustrates a side perspective view of a wheeled platform apparatus according to one embodiment. The wheeled platform apparatus preferably includes a platform 22, 23, 24, which operates as a chassis, having a rear portion which may also be referred to as a back portion 22, a center portion which may also be referred to as a mid portion 23, a front portion 24, a top which may also be referred to as an upper surface 25, and a bottom surface 26.
In some embodiments, the platform may be made of metal, wood, bio fiber, plastic, polymer, ceramic, composite, acrylic, renewable, recycled, or other suitable materials capable for supporting a user's weight as intended or desired.

In other embodiments, the wheels may be positioned or configured in virtually any known or desired position, including both in the front section 24, side-by-side, inline. For example, when the first wheel 27 and the second wheel 28 are positioned adjacent to the bottom surface 26 of the platform in a manner such that both wheels reside below the area of contact between the wheeled platform apparatus and the user's foot, the user's safety and control of the wheeled platform apparatus is enhanced based at least partially upon the user's ability to steer the wheeled platform apparatus with one foot. Further, it should be understood that the wheeled platform apparatus may include wheels in addition to the first wheel 27 and the second wheel 28.
In other embodiments the first wheel 27 and/or the second wheel 28 may be permanently attached, removable, or retractable to the platform 30.
In other embodiments, the first wheel 27 and/or the second wheel 28 may be attached to the wheeled platform 30 apparatus by a friction fit, snap fit or other suitable fit including this as described above.
In other embodiments, the first wheel 27 and/or the second wheel 28 may be a wheel attached to a swivel capable of orienting in a full 360 degree spectrum on a vertical axis for directional rolling, also known as a caster wheel. Other types of wheels capable of orienting along at least a portion of a 360-degree spectrum may also be used. Such as a ball bearing or spherical trackball.
In yet other embodiments, the first wheel 27 and/or second wheel 28 may be illuminated, via one or more LEDs or other illuminating device, by battery power, induction power, or other suitable means for powering an illumination device.
In other embodiments, for example, positioning the user's footwear or bare foot primarily along the longitudinal centerline 29 of the platform 30 may occur at an angle less than plus or minus 45 degrees from the rolling direction or the longitudinal centerline 29 of the wheeled platform apparatus 30. Other angles are possible and in a manner of the user's preference.
The top surface 25 of the wheeled apparatus may be knurled or otherwise textured for enhancing grip with the user's foot or footwear, thereby enhancing control of the wheeled platform apparatus 30 by the user. Such enhanced control contributes to increased usability by the user for directional steering, performing stunts, maneuvers, and tricks with wheeled platform apparatus 30, and further enhances safety. In still other embodiments, the top surface 25 may have graphics or colors for enhancing aesthetic appeal.
In other embodiments, the top surface 25 may be made of or include a shock absorbing material. such as polymer, gel, rubber, foam or other substance, for providing shock absorption and/or suspension for the wheeled platform apparatus 30 and the user.
In yet other embodiments, the deck plate 25 may include a shock absorbing material. Such as gel, rubber, liquid, encapsulated pockets of gas, foam, or other suitable substance, capable of absorbing mechanical forces, shock and/or providing suspension for the wheeled platform apparatus 30 and the user.
In still other embodiments, a shock absorbing material such as gel, rubber, liquid, encapsulated pockets of gas, foam, or other suitable substance, may be partially or fully embedded within the top surface 25, or may be positioned adjacent to the top portion 25 for providing shock absorption and/or suspension for the wheeled platform apparatus 30 and the user.
In yet other embodiments, the platform may house illumination devices, such as LEDs or lights, for illuminating the wheeled platform apparatus 30. The illumination devices may be powered by battery power, solar power, or other suitable power means.
In yet other embodiments, the illumination devices may be powered by induction motors built into or in conjunction with the first or front wheel and/or the second or rear wheel.
