Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A track structure designed for bearing and guiding movable bodies by means of an elevated bearing track surface fast with at least one guiding upright and borne by a web assembly which is formed of a continuous succession of generally cylindrical tubular elements and which is supported on spaced pylons above the ground, wherein the improvement comprises: a multiplicity of generally planar solid strutting bracket members interposed between said bearing track surface and said web assembly and spaced along the span thereof, said bracket members being of generally triangular shape and having a substantially rectilinear flared end adjacent said bearing track surface and extending crosswise thereof and a substantially circular tapered end adjacent said web assembly and encompassing the same; and support means for said web assembly on said pylons, spaced from said bracket members and comprising a baseplate fitted on top of each pylon, and a strut section fast with both said baseplate and said web assembly.
Claim 2
Dependent Claim
158 words
A track structure designed for bearing and guiding movable bodies by means of an elevated bearing track surface fast with at least one guiding upright and borne by a web assembly which is formed of a continuous succession of generally cylindrical tubular elements and which is supported on spaced pylons above the ground, wherein the improvement comprises: a multiplicity of generally planar solid strutting bracket members interposed between said bearing track surface and said web assembly and spaced along the span thereof, said bracket members being of generally triangular shape and having a substantially rectilinear flared end adjacent said bearing track surface and extending crosswise thereof and a substantially circular tapered end adjacent said web assembly and encompassing the same; and support means for said web assembly on said pylons, spaced from said bracket members and comprising a baseplate fitted on top of each pylon, and a strut section fast with both said baseplate and said web assembly.
