Convertible Skateboards for Multi-Mode Transport

Detachable skateboard truck assembly that can be easily added to a traditional skateboard to convert it into a high maneuverability surfskate. The assembly allows the skateboard to turn much tighter and with greater response than a standard truck. It uses an elastomeric element between the base and upper truck parts that compresses during turns to center the wheels. This eliminates the need for a centering spring and complex mechanisms. The truck can be attached to a skateboard using existing bolt holes, and the elastomeric element is enclosed in housings on both parts. A nut locks the truck together. This allows easy removal without disassembling the skateboard.

A foldable skateboard that can be compactly stored and transported by collapsing into a smaller size. The skateboard has a rear half and a front half connected by a butterfly hinge. Pulleys on the lower ends of the rear and front brackets allow the halves to be folded together. The hinge has leafs that pivot on pins. The rear half has a guide seat with a channel and a wheel. A bolt in the channel connects to a wire rope. The rear leaf has a hole matching the bolt. A return spring keeps the fold closed. The wire rope contacts the wheel when folded.

Personal mobility vehicles like skateboards and scooters with adjustable wheel positions to customize ride characteristics, enable tricks, replace worn parts, and upgrade features without tools. The vehicles have modular wheel assemblies that can be easily swapped between multiple fixed positions on the vehicle frame using complementary structures that tightly engage and prevent rotation when locked. A release feature allows repositioning without tools. The wheel assemblies can be swapped in and out of the frame to change the wheel placement.

Skateboard design that allows voluntary propulsion and turning without pushing. The skateboard has a front deck and rear deck connected by a pivoting connector with an elastic body. Stepping on both decks while twisting them in opposite directions causes the elastic body to compress and then expand, providing propulsion and turns. The elastic body has a groove with arched flesh sections that straighten as it compresses to prevent length reduction. This configuration allows the rider to voluntarily move the skateboard instead of just gliding.

Folding skateboard design that allows compact storage and easy transportation. The skateboard has a folding mechanism where the deck folds in half. The deck consists of two separate plate bodies that can pivot and lock together. This allows the deck to fold into a compact shape for carrying. The folding mechanism is secured by a locking assembly between the plate bodies. The skateboard also has a main support with a cylindrical main column and handle bar, and secondary bars between the handle bar and column. The handle bar has springs to provide tension. The deck attaches to the main support with a snap-in block that connects the deck to the column. This allows the deck to fold around the main support when collapsed.

A skateboard design that allows the rider to easily transform the direction of travel without lifting the board. The skateboard has separate front and rear wheel assemblies that can pivot laterally. This allows the rider to shift their weight to deform the frame and change the gap between the wheels on one side, causing the board to pivot and turn. It's like having independent steering on each end. This allows quicker, more agile turns compared to a traditional skateboard where the whole board has to be lifted and rotated.

A skateboard that provides greater freedom of movement, stability, and turning ability compared to conventional skateboards. The skateboard has a unique front truck design that allows the front wheels to pivot and move independently from the truck base. This allows the front wheels to freely move forward or backward relative to the truck, providing a wide range of dynamic movement from the front end of the skateboard. The rear truck is mounted to the board like a regular skateboard. This allows the skateboard to turn and carve like a surfboard by pivoting from the rear. The front truck's independent wheel movement enables turning and maneuverability without tilting the board. It also allows the skateboard to be pushed forward from a dead stop without pushing off the ground. The front truck's pivoting action captures the feel of a surfboard's keel, while the rear truck provides stability.

Foldable portable skateboard that can be compactly folded and carried in a backpack or waistband. The skateboard has a hinged two-part design where the movable section folds into the fixed section. The hinges allow the skateboard to collapse into a narrower shape for portability. The ends of the skateboard have removable wheel covers to prevent rotation when folded. This keeps the skateboard stable when open and allows it to roll normally. The foldable design allows the skateboard to be easily carried and stored in confined spaces.

Foldable skateboard that is compact, easy to carry, and prevents accidents when placed on the ground. The skateboard folds in half by pivoting the front and rear sections around a central connecting plate. This allows the skateboard to be collapsed into a shorter, narrower shape for storage and transportation. The folding mechanism uses bolts and shafts to securely connect the sections when folded. The folding skateboard takes up less space compared to a fully extended board, making it more convenient to carry and store. Additionally, the folding design prevents accidentally stepping on the skateboard since it is shorter and less likely to be left in the way.

A foldable, portable four-wheel skateboard that can be compactly carried when not in use. The skateboard has a main board with rotatable side plates that contain the wheels. The side plates can fold and stretch with straps to secure the skateboard. The main board folds by rotating knobs that wind a steel wire around them. This wire can be stretched to compress the skateboard. The folded skateboard has a silicone sleeve around the wire to protect hands. A sliding ball clamping mechanism prevents the side plates from bending. The skateboard can be easily carried by hand when folded.

Skateboard truck adapter that improves maneuverability and turning ability by adding a pivoting plate between the truck and the skateboard. The pivoting plate has a smaller pivot angle than the base plate, allowing the truck to turn more easily and rapidly. The plate also tilts on flexible members to absorb shock and dampen vibrations. This provides a smoother ride and more agile turning compared to using the truck directly on the skateboard. The adapter can be easily installed on existing trucks and decks.

A convertible skateboard/scooter that can be easily switched between skateboard and scooter mode. The skateboard has a pivotable bracket in the front that extends beyond the skateboard length. When folded down it creates a gap to grip the bracket. When folded up it locks into place to form a scooter handle.

Convertible skateboard/scooter device that can be easily converted between skateboard and scooter modes and is also easy to transport. The device has a pivotally mounted bracket on the front of the skateboard that is longer than the skateboard length. When folded, the bracket clears the rear of the skateboard and can be gripped for transportation. A locking mechanism fixes the bracket in the folded or extended positions. This allows converting between skateboard and scooter modes by pivoting the bracket. The clearance between the skateboard and bracket makes it easy to grip and carry the folded device.

A multifunctional skateboard that can convert between a regular skateboard and a self-propelled board like a hoverboard. The skateboard has two symmetrical halves that can slide and lock together. The lower ends of the halves have telescoping rails that connect to wheels. This allows the skateboard to be merged into a single board with regular skateboard wheels, or separated into two boards with wheels that can be adjusted for hoverboard-like propulsion using body motion.

A skateboard design that allows flipping the board to convert it for different riding styles and user preferences. The skateboard has a uniquely curved platform that is bent upwardly at one end and downwardly at the other. The trucks can be mounted on either end so that the board can be ridden with the curved end facing upward or downward, enabling different styles of riding depending on the user's preference.

Foldable skateboard that can be easily compacted for carrying and storage when not in use. The skateboard has a board surface with pulleys at the bottom. The board surface has a central section (first board surface) and left/right sections (second board surfaces). The left/right ends of the central section have grooves. The left/right sections have protrusions that fit into the grooves. These protrusions hinge with one end in the groove to allow folding of the skateboard.

A versatile skateboard that can switch between different styles like longboarding and cruising by adjusting the position of a middle plate using pivoting links. The skateboard has a front plate, front wheels, a rear plate, rear wheels, and connecting links. The middle plate pivots on the links to move between a first position where it connects the front and rear plates like a longboard, and a second position where it stacks on the front plate and rides like a cruiser. This allows the skateboard to adapt to different gameplay styles by changing the middle plate position.
