Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
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.
Claim 2
Dependent Claim
103 words
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.
Claim 3
Dependent Claim
31 words
The structure described in claim 1, in which said backbone member lies in a substantially flat plane substantially parallel said course line, to avoid bending said backbone member into compound curves.
Claim 4
Dependent Claim
54 words
The structure described in claim 2, wherein said course line is disposed a substantial distance above the plane of said track rails and defined by a point within a vehicle on said rails located so as to minimize lateral acceleration of passengers in said vehicles due to angular acceleration about the bank angle axis.
Claim 5
Dependent Claim
46 words
The structure described in claim 1, and a plurality of support members extending between said backbone member and said track rails, the lengths of said support members increasing as the bank angle increases, to provide greater beam depth and strength in areas of increased centrifugal force.
Claim 6
Dependent Claim
24 words
The structure described in claim 4, said support members being formed in pre-determined lengths to minimize layout computations and speed construction of said track.
Claim 7
Dependent Claim
29 words
The track of claim 1 wherein said plane of said track rails is banked at angles to provide rolling of a vehicle traversing said tracks about said course line.
