Abstract: A spiral ramp for toy vehicles includes a vertical center pole supported by a base having a receiving socket for the lower end of the pole and a plurality of radially extending feet. A plurality of support clamps are arranged at different positions along the center pole and receive the upper ends of a corresponding plurality of downwardly angled support arms. A plurality of curved track segments are serially joined to form a spiral ramp which is supported by the attachment of the lower ends of the support arms to selected ones of the curved track segments. The height and character of the spiral ramp thus formed is adjustable by moving the plurality of support clamps upon the center pole and adjusting the angle defined by the support arms extending therefrom.
