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 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.

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.

Mobility device with a unique wheel orientation system that allows it to switch between low-speed maneuverability and high-speed stability. The device has four wheels mounted at the corners of a rectangular platform. The wheels can rotate 90 degrees to change the direction of travel. This is achieved using a braking mechanism on each wheel that can be released to allow rotation or engaged to lock the wheel in place. By adjusting the brakes, the wheels can be oriented parallel to the long side of the platform for high-speed straight-line travel or parallel to the short side for low-speed turning in tight spaces.

Device to convert a regular skateboard into a four-wheel scooter by adding a handlebar/joystick that attaches to the skateboard deck. The handlebar can be easily removed and fixed to the skateboard using removable connections. This allows transforming a skateboard into a scooter by attaching the handlebar, and then easily removing it to convert back to a skateboard. The handlebar connects to the skateboard using a fixing piece on the deck and a removable connecting piece. This allows the handlebar to be removed for skateboard use, or attached for scooter use. It also has transport belts to move the skateboard/scooter horizontally when not in use.

Wheeled boards that can be converted to ride on land as a longboard. The boards are formed of flexible materials that allow strength to account for longer length; flexion, rebound, stability and vibration-damping. The boards are assembled of skateboard trucks and structural supports. The support structures are designed for shape-memory while having sufficient stiffness to prevent over-flexion at the middle of the board (bowing).
