  • Patent number: 4060253
    Abstract: Angle pads are removably sandwiched between the truck assemblies and boards of skateboards. These pads have upper and lower surfaces with different interface angles with the respective truck assemblies and boards, that increase or decrease the pivot angle of the truck assemblies relative to the boards and thus selectively change the amount of board tilt required to provide a desired turning of the axles and wheels through the truck assemblies. Thus the angle pads allow selective changing of the magnitude of turning of either the front or rear truck assemblies and wheels to achieve exceptional turning ability or high speed stability.
