A self-propelled, one-wheeled vehicle may include a suspension system configured to dampen up and down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems include a shock absorber, a rocker, a pushrod, bell cranks, and/or a swingarm that couple the axle to the board. The suspension system may be disposed completely below a foot deck of the vehicle.

An auto-balancing transportation device having a compact form. Left and right foot platform sections are coupled for fore-aft tilt angle movement relative to one another. Left and right wheels are provided under the respective foot platforms. With a rider's weight directed primarily downward onto the wheels and not onto the coupling structure, the coupling structure may have sufficient space to house the battery. In addition, more efficient and lighter weight supports and bearing arrangements may be used in the coupling structure. Various embodiments are disclosed.

A carbon fiber reinforced skateboard is formed of laminated wood layers having identified grain directions. Upper and lower wood layers will have a grain direction parallel to a long axis of the skateboard. The skateboard will have interspersed wood layers with identified grain directions perpendicular to the long axis. Carbon fiber reinforcing material is adhered to interior plies of the skateboard along the long axis. A central portion of the reinforcing material is adhered below a central vertical point of the skateboard between the skateboard trucks. Anterior and posterior portions of the reinforcing material are adhered above the central vertical point and are located around the attachment locations for the skateboard trucks. The reinforcing material is located to provide a strengthened spine for the skateboard. A first concavity is located between the skateboard trucks parallel to the long axis. Second and third concavities are located perpendicular to the long axis.

A gripping surface includes a plurality of projections extending away from the gripping surface and a plurality of voids between and defined by the projections. The gripping surface may be disposed on a support surface, such as a deck of a skateboard or a deck of a balance board. The projections may be formed by cutting the support surface with a router, such as a computer numerical control router. The projections may each comprise three or more angles surfaces, whereby angled surfaces of proximal projections are positioned at mirror angles of one another.

An athletic shoe configured for use in sports such as but not limited to floor hockey wherein the shoe of the present invention is operable to provide a rolling lateral movement for the wearer. The shoe of the present invention includes an upper bound to the sole wherein the sole includes sidewalls and a bottom surface. Formed in the bottom surface of the sole is the roller assembly. The roller assembly includes a cavity being defined by four walls. The cavity has a wheel member mounted therein on an axle that is mounted between the front wall and rear wall of the cavity. The mounting of the axle provides the lateral rolling motion. The wheel member is movable between a first position and a second position. In the second position a portion of the wheel member extends beyond the bottom surface of the sole.

A system, method, and apparatus for replicating the experience of snow skiing on dry land using a roller land ski with an ability to move and stop consistent with mechanics of an actual snow ski. Each land ski includes a rigid platform with a binding for engagement with a specialized boot, a pair of biased omnidirectional casters supporting said rigid platform, but mounted to a top surface of said platform, and a pair of trucks with a plurality of wheels along its curved axles. A pair of specialized boots constructed out of flexible lightweight material with a stiff support structure to fortify a user's foot and ankle from the forces created by the land ski are included in this system. The method includes calibration and selection of materials for both the board and boot in order to achieve the desired experience.

A Single-foot Skateboard. The Skateboard has interchangeable components in order to reduce spare part inventory. The footboard of the Skateboard is reversible.

A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information. The vehicle may have a secondary battery chargeable via a three-pin charging port including an input pin, a ground pin, and an identification pin configured to receive an expected identification signal from an external charging circuit.

A multi-degree of freedom ice skate post that connects an ice skate blade to the sole of an ice-skating boot generally comprises a plurality of adjustable elements that include a pronate/supinate platform, a bi-directional module and a side/side module. In some configurations, the pronate/supinate platform is configured to move the ice skate blade in a pronate and supinate direction. In some configurations the pronate supinate platform is connected with the bi-directional module providing movement of the ice skate blade in the fore and aft position. In some configurations the side/side module is connected with the bi-directional module providing movement in a side by side direction. Additional configurations can include vertical adjustments as well.

Methods and apparatus are discussed for an electric powered personal transportation vehicle with electric motors powered by one or more batteries. A set of universal battery mounting hole locations and a reserved space for one or more battery housings exist on a board for the personal transportation vehicle. The reserved space on the board for the one or more battery housings that house one or more battery packs is set to not interfere with an operation of the motors or the wheels. A first battery pack containing the one or more batteries differs in at least one of i) a different amp-hour capacity, ii) a different length, width, or height, and iii) a different shape than another battery pack designed to be physically contained in the one or more battery housings and electrically connect with corresponding electrical connections in the one or more battery housings.
