Abstract
Abstract A tire path, guidebeam, electric rail configuration for a guideway in a people mover system comprises a roadway structure having a pair of spaced tire paths forming a vehicle running surface. A guidebeam is disposed along a centerline between the tire paths to provide generally vertical guidance surfaces above the tire running surface for generally horizontal guidewheels on the vehicles. First and second electric rail units are substantially identically structure and extend along the roadway structure between the tire paths to provide conductive surfaces above the tire running surface for electric collection by brush assemblies on the vehicles. Together, the electric rail units have a predetermined number of electric rails to provide power and signal circuits for the vehicles. The first and second electric rail units are supported on opposite sides of the tire path centerline and at substantially equal distances from the centerline to enable turnaround vehicle operation. Further, the first electric rail unit includes three elongated and electrically isolated power rails and one elongated and electrically isolated signal rail, and the second electric rail unit includes one elongated and electrically isolated signal rail. Each of the electric rail units has mounting means for each of its rails, and the mounting means support the signal rails on the respective electric rail units substantially equidistantly from the tire path centerline and substantially equidistantly above the road surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
278 words
A tire path, guidebeam, electric rail configuration for a guideway in a people mover system employing a transit vehicle having load bearing tires, horizontal guide wheels and electric brush assemblies symmetrically disposed between the tires on opposite sides of the center line between the tires, comprising: a roadway structure having a pair of spaced tire paths forming spaced tire running surfaces for the tires of the vehicle; a guidebeam disposed substantially along a center line between said tire paths to provide generally vertical guidance surfaces above the tire running surfaces for the horizontal guide wheels of the vehicle; electric rail means having a predetermined number of electric rails to provide power and operating signals to the vehicle, said electric rail means comprising: p1 a first electric rail unit extending along said roadway structure between said tire paths and having a first number of electric rails above the tire running surfaces on one side of the center line between the tire paths for permitting electric collection by the brush assemblies on one side of the vehicle; and a second electric rail unit extending along said roadway structure between said tire paths and having a second number of electric rails above the tire running surface on the other side of the center line between the tire paths for permitting electric collection by the brush assemblies on the other side of the vehicle; wherein said electric rail units are symmetrically arranged with respect to the centerline between the two paths to enable operation of the vehicle when oriented in one direction on the roadway structure and when the vehicle is turned around on the roadway structure relative to the one direction.
Claim 2
Dependent Claim
278 words
A tire path, guidebeam, electric rail configuration for a guideway in a people mover system employing a transit vehicle having load bearing tires, horizontal guide wheels and electric brush assemblies symmetrically disposed between the tires on opposite sides of the center line between the tires, comprising: a roadway structure having a pair of spaced tire paths forming spaced tire running surfaces for the tires of the vehicle; a guidebeam disposed substantially along a center line between said tire paths to provide generally vertical guidance surfaces above the tire running surfaces for the horizontal guide wheels of the vehicle; electric rail means having a predetermined number of electric rails to provide power and operating signals to the vehicle, said electric rail means comprising: p1 a first electric rail unit extending along said roadway structure between said tire paths and having a first number of electric rails above the tire running surfaces on one side of the center line between the tire paths for permitting electric collection by the brush assemblies on one side of the vehicle; and a second electric rail unit extending along said roadway structure between said tire paths and having a second number of electric rails above the tire running surface on the other side of the center line between the tire paths for permitting electric collection by the brush assemblies on the other side of the vehicle; wherein said electric rail units are symmetrically arranged with respect to the centerline between the two paths to enable operation of the vehicle when oriented in one direction on the roadway structure and when the vehicle is turned around on the roadway structure relative to the one direction.
Claim 3
Dependent Claim
39 words
A guideway configuration as set forth in claim 1, wherein said first electric rail unit rail unit comprises three elongated and electrically isolated signal rail; and said second electric rail unit comprises one elongated and electrically isolated signal rail.
Claim 4
Dependent Claim
77 words
A guideway configuration as set forth in claim 2, wherein said signal rail on said first electric rail unit and said signal rail on said second electric rail unit have substantially identical structure and are symmetrically disposed relative to each other on opposite sides of the centerline between the tire running surfaces so that the two signal rails are substantially equidistant from the tire path center line and substantially the same distance above the tire running surfaces.
Claim 5
Dependent Claim
75 words
A guideway configuration as set forth in claim 3, wherein said first rail unit has a centerline and the power rails and signal rail thereof each have a centerline, and further including rail mounting means for mounting said first electric rail unit so that the four electric rails, consisting of the three power rails and the signal rail, are arranged with the rail centerlines being located outwardly and substantially equidistant from the rail unit centerline.
Claim 6
Dependent Claim
23 words
A guideway configuration as set forth in claim 1, wherein said first and second electric rail units are mounted independently of said guidebeam.
