A skateboard truck includes a metal bolt called a kingpin and a threaded fastener, called a hex nut, which when combined hold the two main components of a truck together: the baseplate, which is mounted to the bottom surface of the skateboard deck; and the turning part of the truck called the hanger, which is mounted onto the baseplate by means of the kingpin, and affixed tightly into the baseplate by means of a threaded hex nut. Two bushings placed along the shaft of the kingpin and on either side of a flange protruding from the hanger hold the hanger in place by the tightening of the kingpin into the threaded shaft nut fastener. The kingpin is oriented such that a threaded portion of the kingpin (on an end opposite a bolt head portion) is generally facing towards a bottom surface of the skateboard deck.

A human transportation device in the form of a variable length skateboard. The variable length skateboard provides a short embodiment allowing the rider greater handling and stopping ability and a long embodiment providing the rider with increased speed ability. The long and short embodiments can quickly and easily be transitioned between at any time or place by the insertion or extraction of at least one removable center deck section. The deck sections are coupled using thumb screw type fasteners and coupler plates thereby removing a need for tools to make the conversion between embodiments. The variable length skateboard provides its owner with multiple embodiments without having to purchase multiple skateboards.

An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a driver position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is note required. Rider weight activates the motors.

A skateboard truck mountable to a deck of a skateboard, the truck comprising a base plate including a storage cavity formed within the base plate for removably accommodating a storage drawer for storing small items. The storage cavity is arranged facing away from the skateboard deck when the truck is mounted onto the deck. The base plate can include a biasing member disposed at a distal end for propelling the storage drawer outwards from the storage cavity. The storage drawer can include a latch adapted to releasably engage with a drawer retention feature provided within the storage cavity, thus preventing the storage drawer from sliding out of the storage cavity. A release pin is provided within the base plate for releasably engaging the latch to dislodge the latch from the retention feature allowing the storage drawer to slide out from the storage cavity to gain access to the items.

A detachable modular electric skateboard which comprises a board body, wheel frames arranged at the bottom of the board body and provided with wheels driven by external force to travel together with the board body and the wheel frames, a traveling suspension part detachably installed at the end of the board body, and a power supply control part arranged at the bottom of the board body and provided with a detachably-installed battery assembly, and further discloses a remote control device for controlling the electric skateboard. Through the detachable traveling suspension part and the power supply control part, the advantages of existing electric skateboards and ordinary skateboards are integrated, a user can achieve the function switching according to requirements, and the detachable modular electric skateboard can replace daily vehicles driven by manpower and perfectly shows the recreational significance of ordinary skateboards serving as sports equipment.

A truck for a skateboard utilizes spherical balls mounted for rotation beneath the deck of the skateboard such that the balls are freely rotatable in a direction along the longitudinal axis and are less rotatable in a direction transverse to the axis such that the skateboard exhibits behavior expected from a snowboard in snow.

The present disclosure includes a transportation apparatus. The apparatus comprises: a surface to receive a plurality of forces at a plurality of locations thereon; a plurality of force sensors, attached to the surface, to provide information related to the plurality of forces; a plurality of wheels beneath the surface, each of the plurality of wheels being coupled with a motor; and a controller to: determine, based on the provided information, a first plurality of forces at the plurality of locations; determine, based on the first plurality of forces, a reference distribution associated with the plurality of locations; determine, based on the provided information, a second plurality of forces; determine a target speed and a target direction of the apparatus based on the reference distribution and the second plurality of forces; and provide one or more signals to the motors based on the target speed and the target direction.

The wheeled riding device employs a frame system mounted to the bottom of the deck, independent suspension links pivotally connect to the wheel assemblies enabling four wheel independent suspensions. A centrally mounted steering and suspension pivot, provides both steering control and suspension attachment for the shock and spring. The device is controlled by the rider using body movement, and a hand held remote when electrically driven. Whether manually or electrically propelled the invention brings improvements in both steering and ride stability while riding over adverse terrain.

A wheeled system for engagement with a surfboard is provided. Wheeled trucks are configured for removable engagement with a lower surface of a surfboard using mounting plates or recessed connections. The removable engagement of the trucks allow a rider to ride on support surfaces such as the sidewalk, and to remove the trucks to employ the surfboard in the water. The removable trucks may be retrofitted to existing surfboards with an elastic or mechanical engagement, or may be provided in combination with a surfboard.

A vehicle for the movement of a driver includes a rolling element, a carrier element supported by the rolling element, a drive arrangement supported by the carrier element and configured to drive the rolling element, and a control unit, by way of which the drive arrangement is steered in a desired travel direction depending on the inclination of the carrier element and the inclination direction of the carrier element. The vehicle is configured such that during operation of the vehicle, the driver stands freely and balances on the carrier element. In a particular embodiment, the rolling element rolling is a ball and the vehicle can be moved in any desired travel direction via the drive arrangement, with the driver being in contact with the vehicle exclusively by way of the driver's feet, and as the case may be, further by way of the driver's lower legs.
