  • Patent number: 6513815
    Abstract: An in-line roller skate propulsion device comprising a lever and a wheel frame having a top, a bottom, a plurality of wheel axle holes near the bottom, a pivot connection near the top for pivotally connecting the lever to the wheel frame, and a hole and shaft combination for connecting a resilient member. The lever's pivot connection is located forward of the center of the lever. As the lever rotates around its pivotal connection to the wheel frame, the resilient member is stretched. Upon release of the rotating force, the resilient member returns the lever to a point of contact with the wheel frame or a stopping piece attached thereto. This action allows a skater to achieve greater speeds than with regular in-line roller skates while exerting the same amount of energy.
