BACKGROUND1. Field of the Invention
This invention relates to wheel boards and more particularly relates to placement and orientation of wheels on wheel board decks.
2. Description of the Related Art
Wheel boards having a variety of wheel configurations are known. These wheel boards have been in use for a century or more. The skateboard has become more or less popular during periods of recent decades. Advances in materials and technologies have provided a basis for improved wheels, bearings, and decks. For example, a variety of materials have been used to form decks having a range of flexibility characteristics.
More recently wheel boards have been formed with decks having one or more pieces and caster type wheels. Some boards have a combination of casters and fixed axle wheels. However, the effectiveness of the wheel combinations discovered in the prior art is not known. In particular, combination wheel type wheel boards are not currently in wide use.
SUMMARYThe present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available wheel board configurations and manufacturing techniques. Accordingly, the present invention has been developed to provide a wheeled apparatus, system, and method that overcome many or all of the shortcomings in the art. In particular, the wheeled apparatus of the present invention has one or more adjustment mechanisms for adjusting fixed axle positions of one or more centrally located wheels. A predetermined number and position of these wheels can thus remain fixed to achieve desired characteristics during use in one application or under certain conditions. Then the number and/or positions can be changed to achieve a different characteristic as desired.
In a simple form a wheeled apparatus in accordance with one embodiment of the invention includes a deck and a plurality of wheels connected to the deck. The wheels may be configured in a substantially diamond shape to support the deck and a weight of a user. The plurality of wheels in this configuration include a lower set of wheels with each wheel of the lower set being equipped with a castering mechanism to allow the wheels to rotate 360 degrees in a horizontal plane. The plurality of wheels also includes an adjustably supported raised set of wheels configured to allow the apparatus to tilt while the lower set of wheels support the deck and the user.
In another simple form, a wheeled apparatus system in accordance with an embodiment of the invention includes a wheeled sport deck having caster wheels supported at front and rear ends of the deck on a longitudinal fore and aft axis. In this embodiment, the wheeled apparatus system includes at least one adjustment mechanism. A set of laterally positioned central wheels is adjustably supported on the deck by the adjustment mechanism at a position along a length of the deck between the caster wheels.
In another simple form, a method of using a wheel board in accordance with another embodiment includes determining at least one target characteristic including at least one of a strength, stability, maneuverability, and wheel surface contact for a wheel board. The method also includes selectively adjusting at least one of a number of wheels and a position of the wheels to achieve the at least one target characteristic.

As shown in
In an embodiment of an apparatus 200c shown in
In one embodiment, the number of central axes 206/256 with wheels 202/252 is adjustable by the user. For example, in an embodiment of an apparatus 200d shown in
In one embodiment, the height difference 320 between the plane of the wheels 202 and the plate of the second set of wheels 204 is adjustable by the user. (See
For example, the embodiment of
In one embodiment, the second set of wheels 204 is equipped with a castering mechanism 212. The castering mechanism 212 allows the second set of wheels 204 to rotate or swivel 360 degrees in a generally horizontal plane. This gives the apparatus the highest range of motion possible. The horizontal plane rotation of the second set of wheels 204 allows the apparatus to turn at a higher turn angle than would be possible without the castering mechanism 212. The plane of swiveling or rotation may be canted slightly to provide increased stability or for other purposes. The turn angle may be expressed as an angle relative to the second axis 210. Achieving an angle of turn may be accomplished by causing angling of each of the second set of wheels 204 relative to the second axis 210.
In an example shown in
In one embodiment, the castering mechanisms 212 allow the apparatus to travel equally well in both directions along the second axis 210 rather than being unidirectional. This is because the second set of wheels 204 can rotate to accommodate or face the direction of the movement of the apparatus.
In the illustrated embodiments, the substantially diamond configuration of the wheels gives the apparatus stability. In one embodiment, the castering devices 212 on the wheels 204 at the front and rear positions of the diamond configuration are used in conjunction with the fixed wheels 202 at the lateral positions of the diamond configuration to help insure that the deck 100 will be stable in moving in a particular direction of motion while still allowing the apparatus to tilt in the direction perpendicular to the motion. The majority of the motion is in a direction parallel to the axis 210 because of the fixed wheels 202. This configuration gives a combination of stability and maneuverability that cannot be achieved through the use of castering wheels alone or fixed wheels alone.
In one embodiment, the position of the laterally extending central axis 206 along the second fore and aft extending axis 210 is adjustable by the user. The laterally extending central axis 206 may still intersect the fore and aft extending axis 210 at the midpoint of the laterally extending central axis 206, but the laterally extending central axis 206 may be moved to different positions along the fore and aft extending axis 210. For example, the user may move the laterally extending central axis 206 toward the forward facing wheel 204 to improve the stability of the apparatus for faster riding. The user may move the laterally extending central axis 206 toward the rear wheel 204 to facilitate sharper angled turning. This fore and aft adjustment may be facilitated, for example, by one or more through openings or a slot 220 extending along a length of the deck for adjustably supporting the wheels 202/252 (see
The wheel configurations of apparatuses 200a-d and 300 shown in
The operation of adjusting the wheel configuration may include adjusting a number of wheels and/or a position of the wheels to achieve the target characteristic(s). In one embodiment, selectively adjusting includes selectively adjusting a number of centrally positioned wheels that lie between a forward most wheel and a rearward most wheel, as indicated at 515. In a broad range the number of these centrally positioned wheels may be in a range from 1 to 17. In an intermediate range the number may be from 3 to 11. In a narrower range, the number of centrally positioned wheels may be from 5 to 7. An odd number of centrally positioned wheels may correspond to a configuration with a laterally centered wheel plus an even number of centrally and laterally positioned wheels 202, for example. In another embodiment, the operation of adjusting the number of centrally positioned wheels may include selectively adjusting a number of centrally and laterally g positioned wheels between the forward most and a rearward most wheel. The number of wheels may be any number within the ranges set forth above. In specific ranges these centrally and laterally positioned wheels may number from 4 to 8 in one range or from 2 to 4 in an alternative range.
The operation of adjusting the wheel configuration may include selectively adjusting a position of at least one centrally positioned wheel within an extent between the forward most wheel and the rearward most wheel, as indicated at 520 in
The operation of adjusting the wheel configuration may include adjusting a position of at least one centrally positioned wheel to have a lower extent in a higher plane than a lower extent of the forward most wheel and the rearward most wheel. For calculation purposes, it is to be understood that the lower extent of the forward most wheel and the rearward most wheel define a first lower plane 330, as shown in
Position adjustment of the centrally positioned wheels may be practically achieved by an alternative opposite relative movement of one or both of the forward most and rearward most wheels. That is, the adjustment mechanisms and adjustments may be applied to the front and rear wheels instead of the centrally positioned wheels to achieve a similar relative positioning.
In one embodiment incorporating solid deck configurations, the wheels 202 may be attached to a cross bar at a center of the deck in a fore and aft direction of the deck. The user may stand or sit on the deck. In another embodiment, two separate boards or decks may replace the solid deck configuration. Each deck may have one castering mechanism 212 and a caster wheel 204 attached thereto. The two decks may be attached together by a rod. Respective crossbars may be attached perpendicularly relative to the rod to support each of the two separate decks. The wheels 202 may be attached to the ends of the crossbars. In using the wheel board of this two-deck embodiment, the user stands with one foot on each deck. In another embodiment, the wheel configuration is attached to a small sized car body. In the car body embodiment, the user may sit in the car body and lean to shift weight and steer the car.
In one embodiment, the type and size of the wheels can be changed by the user. In one embodiment, the user attaches larger, off-road type wheels for increased traction and rougher terrain. In another embodiment, the user attaches smaller, harder wheels for street riding and increased speed.
It is to be understood that the term axis as used herein may be defined as including one or more axles that support wheels along a particular line. Thus, for example, the laterally extending axes may each include one or more laterally extending axles. Likewise, a fore and aft extending axis may include plural axles disposed on a fore and aft extending line.
It is to be understood that features of the various illustrated embodiments may be applied in any combination without departing from the spirit and scope of the invention. For example more than two wheels may be placed on any laterally extending axis 206 and the laterally extending axis 206 may be placed in a different vertical plane than the fore and aft extending axis 210.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
