A modular ramp system includes a ramp component and a connector releasably joined to the ramp component. The ramp component has first and second inclined surfaces and a connecting portion positioned between the first and second inclined surfaces. The connector has a bottom side formed with first and second coupling sections connectible to the connecting portion. The connector is positionable in a first position in which one of the first and second coupling sections is releasably joined to the connecting portion of the ramp component, and the other of the first and second coupling sections is adapted to releasably couple to a ramp or an external structure, and is positionable in a second position in which the first and second coupling sections are releasably joined to the connecting portion of the ramp component.

A modular field that includes a plurality of coplanar wall segments connected together by a plurality of stanchions and a plurality of corner stanchions to connect together wall segments oriented perpendicular to each other. The size of the modular field may be varied by the number and/or size of wall segments. Lights may be connected to the corner stanchions. One or more doors to allow ingress into the modular field may be connected to adjacent wall segments by the stanchions. Goals may be connected to wall segments at opposite sides of the modular field by the stanchions. The stanchions may include a base plate, a main support pole connected to the base plate, a channel receptacle connected to the base plate, a rear plate connected to the main support pole, a frame connected to the rear plate, a front plate, and a clamp connected to the main support pole.

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 foot-deck-based vehicle includes a support structure having a longitudinal axis, a first foot-deck portion, and a second foot-deck portion. Each of the first foot-deck portion and the second foot-deck portion have a foot support surface. The foot support surfaces of the first and second foot-deck portions are positioned to support first and second feet of a rider respectively. The foot-deck-based vehicle further includes at least one wheel that is rotationally connected to the support structure for rotation about a lateral axis. The first and second foot-deck portions are movably connected at least indirectly to each other and are movable between a use position and a stowage position.

A skating track, in particular of the skateboard ramp type, includes: a self-supporting carrier structure of rigid foam, able to rest on the ground; and a skating surface attached to the carrier structure. The carrier structure has mortises and tenons embedded in the mortises. The skating surface is fixed to the tenons, the tenons and the mortises coupling the skating surface on the carrier structure and holding it in position.

A user powered ride-on device and assemblies to facilitate ride-on device reconfiguration.

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.

The present application discloses a foldable three-wheeled scooter, including a front fork and a frame. A handle bar is provided at the upper end of the front fork, a front wheel is connected to lower end of the front fork by front wheel bracket, and a saddle is provided on the frame. A vertical first groove is provided at the front end of the frame, a horizontal second groove is provided at two sides of the frame, the front fork is embedded into the first groove and is movably connected to the frame by first pin shaft. The front fork is embedded into a first groove and is movably connected to the frame by a first pin shaft. A first folding mechanism is provided in the middle of the front fork.

A foldable longboard composed of a deck split in multiple sections connected on their lower surface with a folding assembly having an indivisible flexible element capable of bending near the interface between the different sections of the deck, allowing therefore said sections to be rotated in one direction to a folded position where the bottom surfaces of each section face each other, while inhibiting said sections to rotate in the other direction, against each other's top surface, when the longboard is in its elongated configuration.
