ABSTRACT:
A three wheeled roller skate includes unique features that enable safe and continuous use over rough or smooth terrain. A pair of rollers are situated below the skater's heel and a single roller is situated at the front, under the skater's toes. The single front roller is mounted on a rotational axis that is angled in relation to the axis for the rear wheels. The front roller includes a "toe-out" angle and an inside camber angle to assist tracking and maneuverability. The skate frame and rollers are also arranged to incline the skater's feet, with the toes lower than the heels in order to shift the center of gravity forward of the heels to add balance stability.
