ABSTRACT:
An occupant propelled roundabout which includes a support base fixed to the ground in substantial upright orientation and having a rotatable hub attached at its upper end. This hub defines a rotational axis which is inclined with respect to a vertical reference. A support arm is attached to a rotating part of the hub and projects outward to attach at a platform provided to carry a user in sitting or standing position. The center of mass of the support arm and platform is offset from the rotational axis, which axis also intercepts a portion of the platform. The platform is attached in an acute inclined relationship with the rotational axis. An upstanding support member is attached at the platform and extends across the rotational axis. A gripping bar or seat member is positioned at the upper end of the upstanding support member to enable the user to partially counter balance against the weight of the platform during rotational motion. The gripping bar or seat may also include an upper platform to permit the user to sit therein, centering his weight near the rotational axis.
