发明名称 Wheeled skate device
摘要 A wheeled skate device has a pair of large primary wheels coupled to a platform. The primary wheels rotate about primary axes of rotation in both forward and rearward directions. A binding can be disposed on the platform to secure the user's feet. The primary axes are located at a height above the platform or binding. The skate device can have a universal wheel coupled to the platform which rotates about a secondary axis of rotation. The universal wheel also pivots about a vertical pivot axis such that the universal wheel turns with the platform without sliding on the support surface. The wheels cooperatively operate in a travel mode and spinning mode.
