发明名称 Combination sleigh and wagon
摘要 A combination sleigh and wagon in which, in summertime, the device serves as a wagon while in wintertime the detachable wheels are removed and the device serves as a sleigh in the snow. The central single front wheel of the vehicle is partially rotatable about an axis for steering purposes, while the runners also serve for steering in wintertime by the provision of structure to laterally incline the front portions of the two parallel runners. Thus the front portions of the two runners may be manually angularly oriented relative to the longitudinal axis of the vehicle for steering purposes, while the balance of each runner remains parallel to the longitudinal axis of the vehicle. In general, the runners are disposed along each edge of the body or platform of the device, parallel with the longitudinal axis of the device. More than two runners may be provided in some cases, as for a very wide vehicle. The vehicle also includes at least two other rotatable wheels mounted at the rear of the vehicle.
