Various powered mobility systems for users are described. The powered mobility system can include at least one powered skate. The powered skate can include a platform, a plurality of wheels, and a motor assembly. The motor assembly can include a motor. The motor can be powered by a power supply. A motor control can be implemented to determine when power is supplied to the motor from the power supply.

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.

A self-propelled, one-wheeled vehicle may include a suspension system configured to provide arcuate, generally vertical motion of a board relative to an axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems may include a shock absorber and a swingarm that couple the wheel assembly to the board.

Provided is a ball skate sole structure which can be customized for each individual or each sport. This ball skate sole structure includes: a base plate having a plurality of first holes and a plurality of second holes; at least one ball roller member, the at least one ball roller member being disposed in the first hole selected from among the plurality of first holes; and at least one brake member, the at least one brake member being disposed in the second hole selected from among the plurality of second holes.

A truck and a skateboard assembly comprised of two trucks and a deck. The truck of the present invention has three rigid bodies and two degrees of freedom. The three rigid bodies comprise: (1) the deck and baseplate assembly for the skateboard assembly, or the baseplate assembly for the truck; (2) the hanger assembly; and (3) the floating kingpin assembly. The three rigid bodies are joined together by three spherical joints and elastomerically coupled and constrained by elastomeric components. The truck of the present invention provides the combined functionality of deep deck lean, improved steering control over a wider range of speed, improved speed stability, and improved suspension compared to existing skateboard trucks.

The invention relates to a skateboard-type vehicle (1) comprising a platform (2) to which a front wheel (9) support assembly (8) is connected, the front wheel being mounted so as to pivot about a pivot axis (C-C) which is inclined with respect to a mean plane (P2) of the ground (S), the projection of said pivot axis in a plane (P3) orthogonal to the mean plane of the ground forming, with the latter, a forwardly open angle (a) of between 65? and 85?, the front wheel being in contact with the mean plane of the ground at a contact point (17) offset towards the rear by a distance (d) of between 60 mm and 150 mm with respect to a point (18) of intersection of the pivot axis with the mean plane of the ground.

Exemplary embodiments are directed to a base plate for a skateboard that includes a body, and first and second pivot cups. The body includes a proximal end and a distal end. The first pivot cup extends from the body at or near the distal end. The second pivot cup is spaced from the first pivot cup and extends from the body at or near the proximal end. The second pivot cup defines an outer perimeter surface having an uninterrupted height. The second pivot cup includes an opening extending therethrough and surrounded by the outer perimeter surface of the second pivot cup. The second pivot cup includes one or more channels extending from the opening and through at least a portion of the second pivot cup. The one or more channels extend through at least the portion of the second pivot cup without extending through the outer perimeter surface.

Apparatus, systems, and methods in which a truck carrying member, for coupling a conventional truck to a skateboard, comprises a pivoting plate and optionally a base plate. For example, the base and pivoting plates are rotatably coupled at a pivot comprising an elastic flexible member that biases the pivoting plate to a default position (e.g., center of the base plate). Preferably, the base plate and pivoting plate each has a mounting surface and a pivoting surface that form an obtuse angle, such that the mounting surface of the pivoting surface extends downward. Another example of a pivoting plate comprises flexible members that allow the pivoting plate to tilt relative to the skateboard.

A skateboard includes a deck, one or more wheels, and a truck coupled to the deck and to the one or more wheels. The truck has a base plate for coupling to the deck, an axle for coupling to the one or more wheels, and a shaft secured to the base plate at one end, and to the axle at the other end. The shaft is capable of rotational movement with respect to the base plate about a first axis. The axle is capable of rotational movement with respect to the shaft about a second axis. First and second linkages extend from the base plate to the axle. The shaft and the first and second linkages work together to convert a leaning motion of the deck into a turning motion of the axle to control steering of the skateboard during use.

An inline skate includes a front wheel mount secured to a bottom of a skate boot; a front wheel rotatably secured to the front wheel mount; a rear wheel mount secured to the bottom of the skate boot; a rear wheel rotatably secured to the rear wheel mount; and a shock absorber disposed between the front wheel mount and the rear wheel mount and including two sets of a positioning member secured to the skate boot; a threaded adjustment member disposed through either the rear or front wheel mount; a first bifurcation element through a biasing member and having one end secured to the adjustment member and the other two ends secured to the biasing member; and a second bifurcation element through the biasing member and having one end secured to the positioning member and the other two ends secured to the biasing member.
