  • Roller skate wheel
    Patent number: 5246238
    Abstract: A roller skate wheel is constructed for rolling in both the forward and lateral directions of the skate. A plurality of rollers are mounted on the wheel hub, each roller rotatable about an axis tangential to a circle on the wheel axis. The rollers conform to a second circle on the wheel axis for contact with a skating surface. Application of friction to the rollers controls the resistance to lateral rolling, thus providing a braking action to the skater.
