发明名称 HILL RACE TRACK
摘要 A roadway for toy vehicles which provides a tall, winding, mountain-like road with two parallel tracks, which can be stored in a box of limited height, comprising a rigid lower member forming lower portions of the tracks and a flexible upper member forming upper portions of the tracks. The upper member can be placed in a substantially flat configuration for storage, or can be placed in a largely helical configuration and supported on top of the lower member to form the upper portion of the roadway. A starting gate at the upper end of the roadway can be used to start a pair of vehicles, or can be swung out of the way to allow moving vehicles received from previous track regions to move into the mountain-like roadway without hindrance.
