A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.

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 device developed specifically to perform adhesive sheet cutting operation, with one antiskid face (Sandpaper), which is applied over a Skateboard Shape upper face. It is a grip (E1), in which rear end a geometric volume (V1) is formed, which upper face (F1) is bent downward; and between bent face (F1) highest region and grip (E1) rear end upper corner is formed by a recess (R1) with C letter shape cross-section, and a knife end (N1) is slightly projected beyond recess (R1), limits, standing over bent face (F1) region.

A suspension system for a motorized or non-motorized roller board includes a truck center housing, a pair of truck wings disposed on opposing sides of the truck center housing, and a pair of wheels connected to the respective pair of truck wings. The truck center housing is configured to engage with a truck assembly coupled to a deck of the roller board. The truck center housing defines a pivot axle cavity that houses a pivot axle, a pivot axle shaft and a pair of torsional springs disposed on each side of the pivot axle coupled to the deck of the roller board. The pair of truck wings includes a front cavity that receives the corresponding torsional spring and a wheel shaft that couples with the pair of wheels. The pair of torsion springs dampen the load of the roller board when a force is exerted on the wheels.

A personal transport system is provided including, in an embodiment, an electrically powered vehicle, a companion remote control, and a companion mobile phone application. The vehicle includes an operator-supporting deck, one or more deck-mounted trucks, one or more axle-mounted wheels on each of the one or more trucks, one or more batteries, and a deck lighting system. The one or more batteries power a motor configured to drive the wheels by way of a pulley system, at least one battery of which is disposed under a battery enclosure. The battery enclosure has a first light indicator system, and the companion remote control has a second light indicator system, each of which is configured for communicating with the operator. The deck lighting system includes a light strip of light-emitting diodes disposed in a groove of the deck configured to change state to communicate with the operator or others sharing a road.

A method for manufacturing a skateboard, includes steps of: foaming an organic polymer material with steam with a temperature at a range of 160-180 C. to produce a foam board as the internal core board; sending the organic polymer material into an oven for heating to 190-210 C. to perform foam molding; cutting the foam board into an internal core layer; cutting the foam board into an upper surface layer and a lower surface layer; and then adhering the upper surface layer and the lower surface layer with the internal core layer together by EVA resin, and wrapping the internal core layer between the upper surface layer and the lower surface layer; printing a pattern layer on a surface of the plate body by laser printing; and casting a layer of the plastic film.

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.

The present disclosure relates to longboard-skateboards and longboard-skateboard conversion kits, and methods for converting a snowboard to a skateboard. A skateboard of exceptionally long length combining properties of a snowboard and a skateboard with additional support provides a unique ride. A longboard-skateboard conversion kit includes: a board from either a new or reclaimed source, skateboard truck assemblies, one or more support structure(s) made of one or more of various firm but flexible materials whose properties allow the support structure to rebound and return to a predetermined state or shape and having the necessary properties to provide added stability to a skateboard deck or snowboard's flexible nature in the form of suspension, thereby controlling the board's shape and deflecting the weight of the user operating the longboard-skateboard, and thereby equalizing the downward force put upon it and reducing unwanted vibrations from normal use on less than perfectly flat terrain.

A quick-release truck system includes a deck plate, a truck plate, and a locking mechanism for releasably locking the truck plate to the deck plate. The deck plate mounts to an underside of a deck of a rideable vehicle, and the truck plate mounts to, or is integrated into, an upper surface of a truck baseplate. The deck plate and the truck plate slidingly engage one another using vertically-staggered complementary coupling means. The coupling means may further be horizontally-staggered to create a tiered configuration. The coupling means include a combination of rails and grooves. Once fully engaged, the truck plate releasably locks to the deck plate. The deck plate and the truck plate may include cut-outs for weight reduction.

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.
