  • Patent number: 4155565
    Abstract: A skateboard capable of being adjusted for different weights and different desired ride characteristics without changing the distance between the fore and aft wheels. The truck assembly is mounted on an angled leaf spring and the leaf spring is slideably engaged against a pad having shoulder guides. The pad mounts against the skateboard and the leaf spring is attached to the pad. In one embodiment, the pad contains slots and is movable in a fore and aft direction to change the spring constant of the leaf spring holding the truck. The leaf spring is fixedly positioned to the skateboard and the pad is free to move in a fore and aft direction as a result of the slots thereby allowing the rider to change the effect of the spring and hence the angle to obtain different ride characteristics.
