  • Patent number: 4497521
    Abstract: The invention relates to a ground engaging member for use in hand or gravity powered vehicles such as hand-trucks, trolleys, push-chairs, bicycles, roller-skates, bobcats, grass-skis and amphibious craft and the like, made of a moulded plastics ball. Incorporated in the ball-like member are two diametrically opposite sockets each accommodating a bearing. Each bearing is arranged to accomodate a vehicle axle assembly. The bearing housing and the socket are correspondingly tapered inwardly so that the bearing housing may be pushed into the socket until it is gripped fully by the walls of the socket, and the socket depth is arranged to be greater than the length of the bearing housing.
