A wheel core assembly for a recreational device such as a skateboard is provided. The orientation of the wheel core assembly can be readily reversed to allow use of both sides of a wheel such as e.g., a side-set wheel. The position of an outer bearing and a spacer can be readily switched to either side of an internal chamber thereby allowing the user to select the orientation of the wheel on an axle. The outer bearing and spacer can be configured for ready removal and installation without the use of special purpose tools.

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.

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.

An apparatus that secures a skateboard platform to a snow ski with a base that has a sliding member and stationary member. An adjustment mechanism urges the sliding member to move toward or away from the stationary member. A stabilizer is movable toward and way from the sliding member via a guide path in the base. The stabilizer has two components that move one inside the other to lengthen or shorten a distance between their respective ends. The sliding member has a protruding portion that fits into a front snow ski binding. The stationary member snaps into the rear snow ski binding. The front binding is sandwiched between the stabilizer and the sliding member.

A sports board comprises, at a minimum, a top layer, a bottom layer, and a core in between them. A structural element with puzzle piece shape fits into a correspondingly shaped seat formed by the core, in between the top and bottom layers. The shape of the structural element prevents the structural element from being dislodged by shock forces frequently associated with use of the board. Machined or molded features are provided that penetrate or partially penetrate the structural element. These features, which are filled or included with resin, adhesive or another chemical bonding agent, resist horizontal shearing between the structural element, the core, and the top and bottom layers. A leading portion of the structural element protrudes out from in between the top and bottom layers, forming a bumper that acts as the first point of contact between the board and the ground or an obstacle.

A skateboard-deck wall hanger includes a base that has a central portion and a plurality of legs connected to and extending away from the central portion. Each leg of the plurality of legs is oriented to extend toward a wall when the base is mounted on the wall. The skateboard-deck wall hanger also includes four posts to be inserted into four respective holes on a skateboard deck. The four posts extend outward from the base and have a spacing that corresponds to a spacing of the four holes. The four posts are oriented to extend away from the wall when the base is mounted on the wall.

A trick scooter comprising a base plate, a support member, comprising a first end and a second end, a handle, comprising a first end and a second end, wherein the handle is attached to the second end of the support member. Furthermore, the base plate is manufactured of elastic and flexible material. Such a trick scooter is advantageous as it is lightweight, easy and safe to handle and does not damage the surroundings or cause injury to people nearby.

A skateboard truck mounting apparatus is provided. The skateboard truck mounting apparatus includes a rigid body, having a first hole and a second hole, where the holes are configured to interface with the holes on a skateboard deck. Both the first hole and the second hole are equipped with self-locking mechanisms.

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 shaft nut assembly permanently affixed within the baseplate. 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 structural element (10) for forming a panel, with an upper plane (12) and lower plane (14) which are parallel and deformed along their plane at intervals by pods (16) which extrude toward the opposing plane with their internal faces mating to one another.
