ABSTRACT:
A flexible track consisting of a plurality of track sections extending laterally of the track, each track section being pivotably coupled to the adjacent track section in a central region, viewed laterally, thereof. The respective facing portions of each pair of adjacent track sections are shaped so as to define an essentially tapered gap on each side of the central region extending inwardly from the lateral periphery of each track section, the gap being widest at said lateral periphery. The top surface of each track section is formed of at least one portion projecting longitudinally of said track on one side thereof and a recess on the other side thereof shaped to receive the longitudinally projecting portion of the adjacent track section, the essentially tapered gap being defined at least in part between the projecting portions and the recesses. The top surface of each section is formed with at least one longitudinally extending slot aligned with the corresponding slot of the other track sections, an electrically conductive element capable of longitudinal extension and contraction during relative pivoting of adjacent track sections extends through the aligned slots and across the gaps.
