An apparatus comprising a platform; a plurality of trucks coupled to the platform; and a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation, wherein the roller assembly is configured for an elastic biasing, wherein the roller assembly is driven by a motor.

A snowboard carrying device that acts as handle by which a snowboard user can carry a snowboard. The snowboard carrying device extends between the boot bindings of a snowboard and does not require modification of the snowboard or boot bindings. The carrying device uses tension to maintain a tight configuration and therefore can remain on the snowboard while the user is snowboarding, avoiding the requirements associated with removal and storage of typical carrying devices.

An ergonomic and rider-friendly auto-balancing personal transportation device. The device may have a central wheel structure with one or more tires and deployable foot platforms located on both sides of the central wheel structure. The platforms may be linked to a handle, such that lifting the handle retracts the foot platforms and releasing the handle may deploy them. The tire size and platform size may be set so that the device is easy to step on to, and the distance to ground when dismounting is reduced. Dual tire and single wider tire embodiments. Embodiments that allow different or multiple rider orientations are also disclosed, as are other features and embodiments.

Some embodiments disclosed herein provide an apparatus for joining two skis to form a splitboard. The apparatus can comprise a first attachment portion configured to attach to a first ski and a second attachment portion configured to attach to a second ski. The first attachment portion and the second attachment portion can be configured to engage to prevent splitboard skis from moving up and down relative to each other, from moving apart in a direction perpendicular to a seam of the splitboard, from sliding relative to each other in a direction parallel to the seam, and from rotating about the seam of the splitboard.

A latching device that joins splitboard skis along lengthwise edges. The latching device can include a bracket assembly and a crossbar assembly. The bracket assembly can be secured to a first splitboard ski. The crossbar assembly can be secured to a second splitboard ski. The crossbar assembly can include a crossbar and a lever rotationally coupled to the crossbar. The bracket assembly can include a bracket. Rotating the lever can apply a compressive force between the lever and the inside edge of the bracket applying a holding force between the first splitboard ski and the second splitboard ski. With the splitboard skis disengaged, the bracket assembly and crossbar assembly can be stowed completely within their respective splitboard ski perimeter boundaries.

A personal transportation vehicle comprises a carrier, a control device, a first pair of wheels and a second pair of wheels, wherein the first pair of wheels are fixed in a direction and the second pair of wheels are mounted on swivels disposed below the carrier, each of the first pair of wheels and the second pair of wheels comprises a first wheel and a second wheel, and the first pair of wheels and the second pair of wheels are arranged aligned and parallel to each other below the carrier, a first controller, a first driving device for driving the first wheel of the first pair of wheels, a second controller and a second driving device for driving the second wheel of the first pair of wheels. The control device is configured to transmit signals to the first controller and the second controller to control the first driving device and the second driving device, such that the second pair of wheels are swiveled and driven by a difference between the rotational speeds of the first wheel and the second wheel of the first pair of wheels to determine a movement direction of the transportation vehicle.

This invention is directed toward a portable and easy to set up retractable cord system with means to allow athletes to move along specified routes and to form space indicators that show zone areas.

Skateboard having a board with a first platform and a second platform, fastenings fixed to the board, wheels rotatably mounted in the fastenings in order to move the board, a first frame-fixed to the first platform and a second frame fixed to the second platform, and connection means rotatably connecting the first frame to the second frame in such manner that the skateboard can be in an open position, in which the first platform and the second platform are aligned and coplanar, and in a closed position, in which the first platform and the second platform are parallel and disposed on different planes.

A foot-deck-based vehicle, a front wheel support, and at least one accessory therefor are provided. The foot-deck-based vehicle having a foot-deck with a front end, a rear end, and at least one rear wheel proximal to the rear end. The foot-deck-based vehicle has a front wheel support comprising a pair of wheel interfaces, each of which is couplable to a front wheel, a main body extending between the wheel interfaces and coupled to the foot-deck, and at least one recess in the main body. At least one accessory is snugly securable within the at least one recess of the front wheel support, wherein the main body has a first stiffness when the at least one accessory is removed from the at least one recess, and has a second stiffness that is greater than the first stiffness when the at least one accessory is snugly secured within the at least one recess, wherein the first stiffness and the second stiffness are resistances to bending under a bending load applied to the front wheel support through the foot-deck when the foot-deck supports a person.
