Abstract:     A track for vehicles which is particularly adapted for amusement park rides having a plurality of banked curves. The track comprises a pair of track rails connected to a lower backbone pipe. In curved sections, the plane of the track rails extends at varying banked angles around the course line of the track. In such sections, the distances between the plane of the track rails and the backbone pipe varies in direct relationship to the bank angle of the curve. The distance between the plane of the track rails and the course line remains constant. The plane of the backbone pipe also remains parallel to the plane of the course line. The course line is preferably disposed a substantial distance above the plane of the track rails.

Show all 6 claims
I claim:     1. A track for vehicles comprising a pair of spaced parallel track rails connected to a backbone member disposed beneath said track rails, said track having a plurality of curved sections in which the plane of said track rails extends at varying bank angles around a course line coextensive with and at a constant perpendicular distance thereto, the distance between the plane of said track rails and said backbone member in said curved sections varying in direct relationship to the bank angle of the curve, while the vertical distance between two parallel planes containing, respectively, said backbone member and said course line remains constant.
